Description

  The present invention relates to a finger plug prevention tool for preventing finger padding at a connecting portion of a folding door, and a folding door provided with the same.

The folding door is used as, for example, a storage space such as a closet, a storage cabinet such as a cabinet, an opening / closing door of a room, or a sliding wall (opening / closing wall) for partitioning a room. 2. Description of the Related Art A member in which a hinge pin of a member is used as a folding fulcrum and connected so as to be foldable around the folding fulcrum is known.
In the folded door as described above, a plurality of door plates are arranged side by side in a straight line. Moreover, when opening the folding door, a handle or the like is slid along the guide rail or the like to make a transition (opening) to an open state, and the door plate is moved in a direction perpendicular to the guide rail. A plurality of door plates are folded so that the connecting portion protrudes to be in an open state.
When closing the folding door that is in the open state, a handle or the like is slid along the guide rail to move to the closed state (closed movement), but it is formed between the connected door plates. In a state where the connecting angle (opening angle) is a certain degree (for example, about 80 ° to 100 ° or more), by pushing the vicinity of the connecting portion protruding as described above of the folding door toward the guide rail side The folding door can be closed.

By the way, as for the folding door, although each doorplate is connected by connection members, such as a hinge, as mentioned above, a slight clearance gap is formed between the end surfaces by the side of the connection part of each doorplate. The gap is relatively small, for example, about 0.7 mm to 1.3 mm in a state where the folding door is completely opened and closed, although it depends on the shape and arrangement of the connecting member. However, when shifting from the open state to the closed state, especially in a state in which closing is possible even by pushing the vicinity of the connecting portion as described above, a gap of, for example, about 4.0 mm to 5.0 mm at the maximum. Is formed.
Although this gap is not a gap where an adult's fingers are pinched, there is a risk that an infant or the like may pinch fingers in the gap. Such a gap can be reduced to some extent by, for example, embedding a hinge on the mounting surface side (for example, the back side) of the door plate, and the pinching (fingering) of fingers in the gap can be reduced temporarily.

As another structure for preventing the finger padding in the gap as described above, for example, chamfering the end surface of the connecting portion side of the door plate, or so that finger padding does not occur between the end surfaces of the parts not connected by a hinge or the like. A large gap or a soft member interposed between the end faces has been proposed (for example, Patent Document 1 below).
In each of these structures, it is difficult to completely prevent fingering at the connecting portion of the folding door, and the appearance is not good.

Moreover, in the following patent document 2, in the folding door which consists of several doors (doorboard) connected so that folding is possible by connection members, such as a hinge, folding of the folding door of any one of the connected doors is carried out. In some cases, a folding door connecting portion structure has been proposed in which a band-like member is fixed to the connecting side end of the surface facing the other door.
The belt-like member is fixed along the vertical direction on the back side of the end of one of the two connected doors and on a portion where no hinge is arranged. Moreover, this strip | belt-shaped member makes a protrusion semicircular, and makes the radius the same diameter as the operating radius of a hinge.
According to this, when opening and closing the door, the edge of the door always comes into contact with the outer periphery of the protruding portion, and the gap in the connecting portion of the door is blocked by the protruding portion of the band-shaped member, It is described that there is no gap when the folding door is opened and closed, and finger padding can be prevented.
Japanese Utility Model Publication No. 63-23482 (see FIG. 2) JP 2004-68375 A (see FIGS. 3 to 5)

According to the folding door connecting portion structure described in Patent Document 2, when the folding door is opened and closed, finger padding in the gap between the connecting portion side end surfaces of the door plate formed by the connecting member as described above is performed. Prevention is possible.
However, not only the gap formed by the connecting member as described above, but also a space that is expanded and contracted between the connecting portion side end faces as the folding door is opened and closed is formed between the connecting portion side end surfaces of the plurality of door plates. Is done. In the folding door connecting portion structure described in Patent Document 2, consideration has not been given to finger padding in the space expanded and contracted as described above, and further improvement has been desired. That is, in the folding door connecting portion structure described in Patent Document 2, if a finger is present in the space when the folding door is closed, the width between the end faces is reduced with the transition to the closed state. Therefore, there is a risk that fingers are caught between the end faces.

Moreover, in the connection part structure of the folding door described in the said patent document 2, since the said strip | belt-shaped member is located in the back side in the state by which the folding door was completely closed, in the state seen from the front side, There is no such thing as disturbing aesthetics.
However, in this case, when the belt-like member is in the open state, the hinge is exposed at a location where the belt-like member is not fixed, and coupled with the exposure of the belt-like member, the hinge and the belt are formed at the connecting portion. There was also a problem that the members were exposed alternately and the appearance was poor.

  The present invention has been made in view of the above circumstances, and a finger-clogging prevention device that can prevent a finger from being caught in a gap or a space formed in a connecting portion of the folding door without impairing the aesthetics of the folding door, and It aims at providing the folding door provided with this.

  In order to achieve the above-mentioned object, the finger-clogging prevention device according to the present invention is a finger-clogging prevention device for preventing finger-clogging at a connecting portion of a folding door in which a plurality of door plates are foldably connected around a folding fulcrum. And a bar-like member interposed along the vertical direction in the connecting portion of the folding door, and a support means for movably supporting the bar-like member, the support means supporting the bar-like member on the folding fulcrum side. An urging member urging toward the urging member, and a pair of support bases that are connected to the urging member and are respectively attached to both end surfaces on the connecting portion side of the plurality of door plates. With the opening and closing of the folding door, when the folding door is closed, the space between the end faces on the connection part side of the plurality of door plates is moved in a direction away from the folding fulcrum, while when the folding door is opened, the folding fulcrum is moved to the folding fulcrum. Front in the direction of approach Characterized in that it is structured to move the space between coupling part-side end face.

  In the finger clogging prevention device according to the present invention, the side surface portion on the folding fulcrum side of the rod-shaped member is formed in a convex curved surface shape, and the side surface portion abuts on the end surface on the connection portion side and the connection portion. It is good also as a structure which moves the space between side end surfaces.

  In order to achieve the above object, the folding door according to the present invention is a folding door in which a plurality of door plates are connected so as to be foldable around a folding fulcrum, and is interposed along the vertical direction at a connecting portion of the folding door. And a supporting means for movably supporting the rod-shaped member, the supporting means biasing the rod-shaped member toward the folding fulcrum side, and the biasing member And a pair of support bases respectively attached to both end faces of the plurality of door plates on the connecting part side, and the folding member is opened when the folding door is opened and closed. The space between the connecting portion side end faces of the plurality of door plates is moved in a direction away from the door, and at the time of opening, the space between the connecting portion side end faces is moved in a direction approaching the folding fulcrum. Features.

  In the folding door according to the present invention, the side surface portion on the folding fulcrum side of the folding member is a convex curved surface, and the side surface portion is in contact with the end surface on the connection portion side, and between the end surfaces on the connection portion side. It is good also as a structure which moves this space.

In the folding door according to the present invention, a chamfered portion is formed on each of the connecting portion side end surfaces of the plurality of door plates, and the bar-like member is chamfered with the folding door closed. It is good also as a structure in which at least one part is accommodated between parts.
In the folding door according to the present invention, the rod-shaped member may be substantially the same length as the vertical length of the folding door.

The following effects can be obtained by using the fingernail preventer according to the present invention for a folding door.
That is, since the bar-shaped member is interposed along the vertical direction in the connecting portion of the folding door, the gap between the door plates is concealed by the bar-shaped member. Therefore, it is possible to improve the aesthetics of the folding door and to prevent finger filling in the gap. The length of such a bar-shaped member may be at least as high as the reach of an infant or the like in accordance with the height of the infant or the like, but over the substantially entire length of the folding door in the vertical direction. If the length is interposed, the bar-like member conceals the gap between the door plates over the entire length in the vertical direction, and the aesthetics can be further improved.

  In addition, the bar-shaped member of the anti-clogging tool moves along the space between the end faces of the plurality of door plates in the direction away from the folding fulcrum when the folding door is closed as the folding door is opened and closed. When the folding door is opened, the space between the end faces on the connection part side is moved in a direction approaching the folding fulcrum. Therefore, when the folding door shifts from the open state to the closed state, the bar-shaped member moves as described above in the space formed between the connecting portion side end faces of the door plate, and thus fingers exist in the space. Even in the state, by moving the rod-shaped member in the direction away from the folding fulcrum, fingers are prevented from being pushed out of the space, thereby preventing the fingers from being stuffed.

In the finger clogging prevention device according to the present invention, the side surface portion on the folding fulcrum side of the bar-shaped member is formed in a convex curved surface shape, and the side surface portion abuts on the end surface on the connection portion side, so If it is made the structure which moves the space between, there exist the following effects.
That is, in the state where the finger clogging prevention tool is used for a folding door, the side surface portion of the rod-shaped member that is a convex curved surface moves in contact with the connecting portion side end surface, so that each connecting portion side end surface of the door plate, A gap is not formed between the rod-shaped member and finger filling can be reliably prevented.

In the finger clogging prevention device according to the present invention, as the support means, a biasing member that biases the bar-shaped member toward the folding fulcrum side, and a support base that is connected to the biasing member and attached to the folding door When the rod-shaped member moves, it moves in contact with the end face of each connecting portion of the door plate. Therefore, it is possible to reliably prevent finger jamming.
In the said structure, you may make it make the movement to the direction away from the folding fulcrum of a rod-shaped member by another means. Alternatively, if a rod-shaped member having a convex curved surface at the folding fulcrum side as described above is adopted, the rod-shaped member is connected to the door plate that gradually narrows as the folding door is closed. In the above-mentioned space between the part side end surfaces, the movement in the direction away from the folding fulcrum is performed against the urging force toward the folding fulcrum side by the urging member so that the convex curved surface of the side surface part follows each of the end surfaces. Made smooth.

  Moreover, in the fingernail preventer provided with the support base, if the support base is a pair of support bases that are respectively attached to both end surfaces on the connecting part side of the plurality of door plates, the folding door to be attached is For example, the support base can be easily attached to the folding door from the near side by opening it halfway or opening it and exposing the both end faces on the connecting portion side to the near side. Further, in the state where the folding door is closed, the support base is in a state of being accommodated between each end face of the adjacent door plate, for example, compared with the support base attached to the back side of the door plate, The aesthetics on the back side of the folding door can be improved.

In addition, the folding door according to the present invention includes a bar-like member interposed along a vertical direction at a connecting portion of the folding door, and a support unit that supports the bar-like member so as to be movable. In addition, when the folding door is opened and closed, the bar-shaped member moves in the space between the end faces of the plurality of door plates in the direction away from the folding fulcrum when the folding door is opened, while the folding fulcrum is opened when the folding door is opened. It is set as the structure which moves the space between the said connection part side end surfaces in the direction which approaches.
Therefore, according to the folding door which concerns on this invention, while being able to improve the aesthetics of the said folding door similarly to the effect which the said finger padding prevention tool show | plays, the finger padding in the connection part of the said folding door can be prevented.

In the folding door according to the present invention, the side surface portion on the folding fulcrum side of the folding member is a convex curved surface, and the side surface portion is in contact with the end surface on the connection portion side and between the end surfaces on the connection portion side. If it is set as the structure which moves space, the finger filling in the connection part of the said folding door can be prevented reliably like the above.
In the folding door according to the present invention, as the support means, a biasing member that biases the rod-shaped member toward the folding fulcrum side, and a support base that is connected to the biasing member and attached to the folding door. If provided, similarly to the above, it is possible to reliably prevent finger filling at the connecting portion of the folding door.
Further, in the folding door provided with the support base, if the support base is a pair of support bases respectively attached to both end surfaces on the connection portion side of the plurality of door plates, the folding door is connected to the folding door from the front side as described above. While being able to attach easily, the aesthetics of the back side of a folding door can be improved.

  In the folding door according to the present invention, a chamfered portion is formed on each connecting portion side end surface of the plurality of door plates, and the chamfered portion of the door plate in the state where the folding door is closed. If at least a part of the structure is accommodated in between, the protruding amount of the rod-shaped member at the connecting portion is reduced, and the folding door is excellent in aesthetics.

  In the folding door according to the present invention, if the rod-shaped member is substantially the same as the vertical length of the folding door, the rod-shaped member conceals the gap between the door plates over the entire length in the vertical direction. As a result, aesthetics can be improved.

4 (a) and 4 (b) both show the same folding door, (a) is a partially broken schematic front view seen from Y1 in FIG. 1, and (b) is one seen from Y2 in FIG. FIG.

In each of the following reference examples and embodiments, the surface side provided with the operation tool such as the handle of the folding door in the installed state, that is, the direction in which the connecting portion of the door plate is orthogonal to the guide rail when folded. The space side that protrudes toward the front side is referred to as the front side, and the opposite is assumed to be the back side. That is, when each folding door is constructed as an open / close door for a storage space such as a closet as in each reference example and each embodiment described later, the folding door faces the folding door on the indoor space (residential space) side. The space where the user who opens and closes the door is the front side, and the storage space side is the back side.

As shown in FIG. 1, the folding door 10 according to this reference example is roughly composed of two door plates 11 and 13, a connecting member 15 that connects the door plates 11 and 13 in a foldable manner, and the connecting member 15. And the finger plug prevention tool 20 provided in the connection part cp of the door plates 11 and 13 connected by.
In the present reference example , the folding door 10 has two sets of openings op formed in the inner wall 1 that partitions the interior space (residential space) LS of the building and the storage space SS, as shown in FIG. An open / close door for a closet that is closed or opened by the folding doors 10 and 10 is configured.

Each of the folding doors 10 is arranged in a four-sided frame (upper frame (not shown), lower frame 2, vertical frames 3 and 3) provided in the opening op, and an upper rail (not shown) and lower frame of the upper frame. 2 is supported by the lower rail 2a so as to be freely opened and closed.
One of the two door plates 11 and 13 is a fixed door plate 11 that is not slidable, and the other is a movable door plate 13 that is slidable. That is, the pivot 11a of the door plate 11 is supported by the upper and lower frames 2 in the vicinity of the vertical frame 3 so as to be rotatable and non-slidable. The pivot 13a of the door plate 13 is supported by the upper rail and the lower rail 2a. The upper frame and the lower frame 2 are supported so as to be slidable and rotatable. A configuration that enables sliding of these door plates may employ a known runner (such as a rolling element or a traveling body) or a pivot.
In the figure, reference numeral 16 denotes a handle (handle) as an operation tool provided on the door plate 13. The fixed door plate 11 may also be configured to be slidable.

Further, the end faces 12 and 14 on the connecting part cp side of the door plates 11 and 13 are chamfered parts 12a and 14a whose front side parts are formed by C chamfering or the like. The shape of these chamfered portions 12a and 14a is such that the folding door 10 is closed and the chamfered portions 12a and 14a are opposed to each other, and expands toward the front side (the interior space LS side) in plan view. Has been.
In this reference example , the connecting member 15 is a hinge 15 having a hinge pin 15a and a pair of attachment hoods 15b and 15b that can be folded around the hinge pin 15a as a fulcrum. That is, in the present reference example , the hinge pin 15a constitutes the folding fulcrum of the door plates 11 and 13.
As shown in FIG. 4 (b), the hinge 15 is fixed to the back surface of the door plates 11 and 13 in the vicinity of the connecting portion cp by fixing the attachment honey 15b and 15b with wood screws or the like. . A plurality (three in the illustrated example) of hinges 15 are provided at appropriate positions along the vertical direction of the connecting portion cp.

In the folding door 10 having the above-described configuration, the state in which the two door plates 11 and 13 are arranged side by side as in the folding door 10 located on the left side in FIG. Like the folding door 10 that is positioned, the state in which the two door plates 11 and 13 are folded toward the front side (direction perpendicular to the upper rail and the lower rail 2a) so that the connecting portion cp protrudes is an open state. Is done.
Further, the state in which the folding door 10 located on the right side in FIG. 1 is indicated by a two-dot chain line is in the middle of the transition from the closed state to the open state (opening) or from the open state to the closed state (closed motion). ) And a closed state are shown.
The folding door 10 is opened and closed by the handle 16, and the angle θ (opening angle θ) formed by the back surfaces of the connected door plates 11 and 13 at the closing time is, for example, 80 In a state where the angle is about 100 ° or more, the folding door 10 can be closed and closed by pushing the vicinity of the connecting portion cp of the folding door 10 from the front side (the indoor space LS side) toward the back side (the storage space SS side) ( Hereinafter, it is referred to as “pressing closing movement”.

As described above, when the folding door 10 is opened and closed, between the connecting portion side end surfaces 12 and 14 of the door plates 11 and 13, as will be described later, as the folding door 10 is opened and closed, enlargement and reduction are performed. A fan-shaped space fs (see also FIGS. 2 and 3) is formed.
In the fan-shaped space fs that is expanded and contracted as the folding door 10 is opened and closed, the bar-shaped member 21 of the finger plug prevention tool 20 that moves toward the back side and the near side when the folding door 10 is opened and closed is interposed. .

As shown in the enlarged view in the alternate long and short dash line in FIG. 1, the finger clogging prevention device 20 is generally interposed in the connecting portion cp of the folding door 10 along the vertical direction, and on the front side of the hinge 15. An interposed rod-shaped member 21 and support means 24 that movably supports the rod-shaped member 21 are provided.
In the present reference example , the rod-like member 21 has a long hollow cylindrical shape as shown in the figure, and both the front side portion 22 and the back side portion 23 of the rod-like member 21 have a convex curved shape. ing.
That is, in this reference example , the bar-like member 21 has a convex curved surface at the back side portion 23 which is a side portion on the hinge pin 15a side.

The shape of the back side portion 23 having the convex curved surface shape is not limited to that having a semicircular cross section as shown in the figure. For example, until the back side 23 is completely closed from the state of the opening angle θ that enables the pressing and closing, the end surfaces 12 and 14 of the door plates 11 and 13 (the chamfers 12a and 14a are also chamfered). It is good also as a shape which always contacts | abuts.
Further, as shown in FIG. 4A, the rod-shaped member 21 has substantially the same length as the vertical length of the folding door 10.

Further, the horizontal width of the rod-shaped member 21 is a gap formed between the end faces 12 and 14 (between the rear side edges of the end faces 12 and 14) in a state where the maximum width is as shown in FIG. It is at least larger than the width of g. Moreover, in this reference example , the horizontal width of the rod-shaped member 21 is substantially the same as the width between the chamfered portions 12a and 14a (between the front side edges of the chamfered portions 12a and 14a) in a state where the folding door 10 is closed. It is set to a width or a slightly larger width.
As described later, the shape and size of the bar-shaped member 21 described above are biased toward the back side by a bar-shaped rubber body (biasing member) 25 and the connection of the door plates 11 and 13 accompanying the closing movement of the folding door 10. What is necessary is just to design suitably according to the thickness of the doorplates 11 and 13, the shape of a chamfering part, etc. so that the movement of the said rod-shaped member 21 made by the proximity | contact action of the part side end surfaces 12 and 14 may be attained.

  By forming the bar-shaped member 21 as described above and forming the chamfered portions 12a and 14a on the door plates 11 and 13, as shown in FIG. Has a structure in which approximately half is accommodated in the space between the chamfered portions 12a and 14a. Thereby, the protrusion amount to the near side of the rod-shaped member 21 becomes smaller than, for example, a folding door in which a chamfered shape is not formed on each connecting portion side end surface of the door plate, and the aesthetics of the folding door 10 are improved. Be improved.

The rod-shaped member 21 may be made of, for example, a metal material or a hard synthetic resin material.
The metal material may be any material such as steel, carbon steel, stainless steel, aluminum, aluminum alloy, etc., but may be made of aluminum that is relatively light and inexpensive compared to steel materials. By being made of an aluminum material in this way, the color tone becomes silver, and the aesthetic appearance is excellent in a state of being arranged between the door plates 11 and 13.

The support means 24 always urges the bar-shaped member 21 toward the back side (hinge pin 15a side) from a state where at least pressing and closing is possible until the folding door 10 is closed and closed. And a fixed rubber plate (support base) 27 connected to the rod-shaped rubber body 25 and attached to the folding door 10.
As shown in FIG. 4B, a plurality (three in the illustrated example) of the support means 24 are provided at appropriate positions along the vertical direction of the connecting portion cp.
The rod-like rubber body 25 is inserted into an insertion hole or the like provided in the back side portion 23 of the rod-like member 21, and its base end portion is fixed to the rod-like member 21 and extends in a rod shape toward the back side. The other end is inserted into the insertion hole of the fixed rubber plate 27 and fixed by the stopper 26.

In the state where the folding door 10 can be pressed and closed (see FIG. 2A), the rod-like rubber body 25 is at least in the natural length state so that the back side portion 23 of the rod-like member 21 is connected to each door plate 11. , 13 has a length that can be brought into contact with each of the end faces 12, 14. Further, the bar-like rubber body 25 can support the bar-like member 21 in a state where it is moved to the front side as will be described later in a state in which the folding door 10 is completely closed (see FIG. 3B). In addition, it is possible to extend with the elastic deformation.
The fixed rubber plate 27 is bridged across the gap g, and is fixed to the back surface of the door plates 11 and 13 in the vicinity of the connecting portion cp by fixing tools 28 and 28 such as wood screws (FIG. 2). And also FIG. 3). The support base connected to the rod-shaped rubber body 25 is not limited to the fixed rubber plate 27 as described above, and any support base that can support the rod-shaped rubber body 25 and can be attached to the folding door 10 is used. It may be anything. Further, the shape of the rod-shaped rubber body 25 is not limited to a rod shape, and may be a thin plate shape that can be inserted into the gap g.

  According to the finger clogging prevention device 20 having the above configuration, it can be retrofitted to the existing folding door 10. For example, the rod-like member 21 to which the rod-like rubber body 25 is attached is interposed on the front side of the hinge 15 of the folding door 10, the rod-like rubber body 25 is inserted into the gap g, and the other end portion of the rod-like rubber body 25 is inserted. Is inserted into the insertion hole of the fixed rubber plate 27 and fixed by the stopper 26. Next, the fixed rubber plate 27 may be attached to the existing folding door 10 by fixing the fixed rubber plate 27 to the back surfaces of the door plates 11 and 13 with the fastening devices 28 and 28.

Next, based on FIG.2 and FIG.3, the finger-clogging prevention structure of the said folding door 10 at the time of closing and opening of the folding door 10 is demonstrated.
First, as shown in FIG. 2 (a), in a state where pressing and closing are possible, the bar-like member 21 has its back side portion 23 in the vicinity of the back side of each end face 12, 14 of each door plate 11, 13. The rod-shaped rubber body 25 is brought into contact with and extended with a natural length or elastic deformation.
From the above state, the front side surfaces of the door plates 11 and 13 in the vicinity of the connecting portion cp of the folding door 10 are pushed toward the back side, or the folding door 10 is slid by holding the handle 16 to FIG. As shown, the fan-shaped space fs formed between the end faces 12 and 14 of the door plates 11 and 13 gradually decreases with the closing movement. Thus, as the space fs becomes smaller, the end surfaces 12 and 14 of the door plates 11 and 13 gradually approach each other. Along with this proximity, the rod-like member 21 resists the biasing force toward the back side of the rod-like rubber body 25 so that the back side portion 23 having a convex curved surface slides on the end surfaces 12 and 14, The space fs between the end faces 12 and 14 moves toward the front side. That is, the rod-shaped member 21 moves in a direction away from the hinge pin 15a.

When further closing is performed from the above state, as shown in FIG. 3A, the bar-like member 21 is moved forward between the chamfered portions 12a and 14a of the end surfaces 12 and 14 of the door plates 11 and 13, as described above. Move towards the side.
Further, when the door is further closed from the above state, as shown in FIG. 3B, the folding door 10 is completely closed. In this state, the rod-shaped member 21 is supported by the rod-shaped rubber body 25 in a state where substantially the entire back side portion 23 is accommodated in a space formed between the chamfered portions 12 a and 14 a of the door plates 11 and 13. ing.
That is, as described above, the finger clogging prevention device 20 has a structure in which the rod-like member 21 protrudes to the near side as the folding door 10 is moved away from the hinge pin 15a.

On the other hand, when opening the folding door 10 from the state shown in FIG. 3B in which the folding door 10 is completely closed, the handle 16 (see FIG. 1) is directed toward the door plate 11 side on the front side and the fixed side. Opening is done by pulling.
When the folding door 10 is opened, the bar-shaped member 21 is always moved from the closed state to the state in which the bar-shaped rubber body 25 can be at least pressed and closed by the bar-shaped rubber body 25. Since it is urged | biased toward the side, between each chamfering part 12a and 14a of each end surface 12 and 14 of each doorplate 11 and 13 (refer Fig.3 (a)), and each end surface 12 and 14 of each doorplate 11 and 13 The space (see FIGS. 2B and 2A) is sequentially moved toward the back side. That is, it moves in a direction approaching the hinge pin 15a.
In the state where the folding door 10 is completely opened from the state shown in FIG. 2A, the rear side portion 23 of the rod-shaped member 21 is a hinge pin of the hinge 15 as shown in the enlarged view in the dashed line in FIG. The contact to 15a is restricted and the movement to the back side is regulated. In addition, it is good not to restrict | limit to the hinge pin 15a in the state open | released completely in this way, but to contact | abut to the back side vicinity of each end surface 12 and 14 of each doorplate 11 and 13.

As described above, according to the folding door 10 provided with the finger clogging prevention device 20 according to the present reference example , the rod-shaped member 21 is interposed on the front side of the hinge 15 along the connecting portion cp of the folding door 10 in the vertical direction. Therefore, when viewed from the front side, the bar-shaped member 21 conceals the gap g between the door plates 11 and 13 and also conceals the hinge 15. Therefore, the aesthetics of the folding door 10 can be effectively improved and finger filling in the gap g can be prevented.
In particular, in the present reference example , the length of the bar-shaped member 21 is a length that is interposed over substantially the entire length of the folding door 10 in the vertical direction, and therefore the gap g between the door plates 11 and 13 is formed by the bar-shaped member 21. And all of the hinges 15 are concealed, and the aesthetics are further improved.

Further, as described above, the bar-shaped member 21 of the finger clogging prevention device 20 opens the space fs between the end surfaces 12 and 14 of the door plates 11 and 13 when the folding door 10 is closed as the folding door 10 is opened and closed. While moving toward the side, when the folding door 10 is opened, the space fs between the end surfaces 12 and 14 is moved toward the back side. Therefore, when the folding door 10 is closed, the bar-shaped member 21 moves toward the front side in the fan-shaped space fs formed between the end surfaces 12 and 14 of the door plates 11 and 13. Even in the state where fingers are present in fs, the fingers are prevented from being stuffed by causing the fingers to be ejected from the space fs by the movement of the rod-shaped member 21 toward the front side.
In other words, in the case where such a rod-shaped member 21 is not provided, as the space fs becomes narrower with the closing movement, the end surfaces on the connecting portion side of the door plates come closer to each other, and fingers are moved to this space when closing. If present, there is a risk that fingers will be pinched, but according to this reference example , such fear can be prevented.

Further, in the present reference example , the bar-like member 21 has the back side portion 23 of each door plate 11, 13 until the folding door 10 is closed and closed from a state where at least pressing and closing is possible. Since it is configured to abut on each end surface 12, 14 and move toward the near side and the back side as described above, between each end surface 12, 14 of each door plate 11, 13 and the rod-shaped member 21. No gaps are formed in the finger, and it is possible to reliably prevent finger filling.
Further, the movement of the bar-shaped member 21 toward the front side and the back side is caused by the biasing of the bar-shaped rubber body 25 toward the back side and the end surfaces 12, 14 of the door plates 11, 13 accompanying the closing movement of the folding door 10. Since it is set as the structure made by a proximity | contact action, the structure of the finger clogging prevention tool 20 can be made into a simple structure.

Moreover, although the said 1st, 2nd embodiment and the 6th reference example have illustrated the aspect which provided the long hole into which an upper and lower end pin part of a rod-shaped member is respectively inserted in the upper and lower support plates, for example, a pin It is good also as an aspect that a rod-shaped member moves and is supported so that it may slide to a lower support plate as a rod-shaped member which is not provided with a part, and as a flat lower support plate which does not form a long hole.

Or in the said 1st, 2nd embodiment and a 6th reference example , you may comprise a support means only by what supports the above-mentioned intermediate part. Even in the case where the supporting means is constituted only by the one that supports the intermediate part in this way, each rod-like shape can be obtained by strengthening the urging force of the spiral spring (spring) constituting the string-like rubber body or the winding body. Support of the member is possible. In the case of the string-like rubber body, it can be supported by being hooked on the small-diameter step portion of the rod-like member. In the case of the winding body, the winding body is fixedly supported in the mounting recess. Therefore, the bar-like member can be supported by the string-like member connected to the winding body.

Further, the first and second at least either one of the upper and lower support plates 37 and 38 explained in the embodiment and the sixth reference example, the first reference example to finger packed preventer according to a fifth reference example You may make it apply to. In this case, each rod-shaped member included in each finger clogging prevention tool may be appropriately modified and applied.

In each of the above reference examples and embodiments, as a means for supporting the finger clogging prevention device, the bar-like member is always attached to the back surface from a state where at least pressing and closing is possible until the folding door is closed and closed. Although the supporting means provided with the urging member urging toward the side and the supporting base connected to the urging member and attached to the folding door is illustrated, the present invention is not limited to this, and each of the rod-shaped members described above As described above, the folding door may be supported so as to be movable toward the back side and the near side. For example, instead of the urging member as described above, a mode in which the rod-like member is always attracted toward the back side by a magnetic attraction force may be employed.

Alternatively, as the folding door is opened and closed, the means for moving the rod-like member to the back side and the near side may be made by other mechanical / electrical means in addition to the biasing member. For example, mechanical means (mechanical actuators) such as gears, cams, link mechanisms, and cylinders, electrical means (electric actuators) such as solenoids and motors, or combinations of these mechanical means and electrical means Thus, the bar-shaped member may be moved to the back side and the near side as the folding door is opened and closed.
Further, when such a bar-shaped member is moved, in each of the reference examples and the embodiments described above, the back side portion of the bar-shaped member is at the connecting portion side of the door plate at least until it is closed from a state in which pressing and closing is possible. Although the aspect which contacts and moves to an end surface is illustrated, it is not restricted to such an aspect, It is good also as an aspect which the back side part of this rod-shaped member moves close to the connection part side end surface of a doorplate.

Further, in each of the above reference examples and each embodiment, each folding door is shown as an example applied to an open / close door for a closet, but is not limited thereto, for example, a storage cabinet such as a cabinet, an open / close door of various rooms, or It can also be applied as a slide wall (opening / closing wall) for partitioning a room.
Furthermore, in each of the above reference examples and each embodiment, the two door plates constituting the folding door are exemplified as two door plates, but may be composed of three or more door plates. In this case, you may make it provide each above-mentioned finger prevention tool at least in the connection part which protrudes in the direction orthogonal to the sliding direction of a doorplate at the time of opening and closing of a folding door.
Further, the connecting member for connecting the door plates is not limited to the hinge, and any member may be used as long as the door plates are connected to each other so as to be foldable around the folding fulcrum. The folding fulcrum may be a virtual fulcrum formed when each door plate is folded.
Furthermore, in each said reference example and each embodiment, although what chamfered part was formed in the connection part side end surface of each doorplate is illustrated, it is good also as that in which the chamfered part is not formed. In this case, in the state where the folding door is closed, each bar-like member is in a mode in which substantially the whole is projected to the front side in a plan view.

Furthermore, the shape of the rod-shaped member provided in the finger clogging prevention tool is not limited to the above-described shape, and may be another shape. For example, the cross-sectional shape may be an oval shape, an oval shape, a flat plate shape, and the like, and in a state where the folding door is closed, a substantially entire structure of the rod-shaped member is not accommodated between the chamfered portions and exposed to the front side. It is good also as a thing.
Moreover, in each said reference example and each embodiment, in the state by which each folding door was open | released completely, although the state which is not open | released until each back surface of an adjacent doorplate becomes substantially parallel is illustrated, Needless to say, each finger-clogging prevention device can be attached to a device that is opened until it becomes substantially parallel .
