Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a rectangular screen door frame,
In particular, it relates to a structure of a door-plate-shaped storage screen door which is mainly composed of a rectangular screen door frame used for a pulling sash.

[0002]

2. Description of the Related Art Conventionally, a screen used for a sash frame around an opening of a building or the like, in particular, a sliding sash frame (hereinafter simply referred to as a sash frame) is a square screen sash frame. It is one in which the four edges of the mesh net are fixed and stretched (hereinafter referred to as "door plate mesh door"). On the mesh door sash forming the above mesh door sash frame, the lower horizontal frame is on the sash frame, and the lower mesh door rail. It is generally mounted slidably. In addition to this door-plate type mesh door, a mesh roll that elastically winds the mesh so that it can be expanded, stretched or closed is stored in the storage case, and if necessary, mesh-shaped from the storage case. A roll screen door formed by pulling out the net and stretching the net against the sash frame to form a screen door, or providing a separate frame outside the sash frame, and folding the net with respect to the separate frame, There is a pleated screen door that can be opened and stored, and a screen screen is formed if necessary.

[0003]

However, among the above-mentioned conventional screen doors, the so-called door-plate screen doors are always mounted on the screen door rails of the sash frame, so that they are always exposed to the air polluted by exhaust gas or the like. , The net itself is very easily polluted, and it is necessary to remove the door plate mesh door before cleaning, the cleaning work is complicated, and there is a danger if the screen door is installed at a high place. Becomes Further, since the door plate-shaped screen door is always mounted on the screen door rail of the sash frame, the net of the door plate-shaped screen door obstructs the field of vision of the human and gives a very annoying impression to the user.

Further, since the door plate type mesh door itself is simply slidably attached to the sash frame, the door plate type mesh door is constantly agitated by a strong wind such as a typhoon, and the screen door sash which constitutes this mesh door. Since the frame is made of a thin screen door sash frame for the purpose of reducing the weight, the screen door sash frame itself has low strength and is easily deformed, and the door plate screen door itself can be easily removed from the sash frame. It may fall out. In addition, since the commercially available door-plate mesh doors are pre-manufactured integrally with each other according to the predetermined sash frame, they must be transported as they are during transportation, and the efficiency of transporting the door-plate mesh doors is extremely high. There is a problem that it decreases.

Therefore, in order to solve the drawbacks of the door-plate type mesh door, a roll mesh door or a pleated mesh door in which a mesh mesh is expanded and stretched with respect to the sash frame is also proposed and implemented. ing. However, in the above-mentioned roll screen door, in order to cover the opening of the sash frame, it is necessary to dispose two left and right roll screen doors on the vertical frame that constitutes the sash frame. If the mesh net is expanded and stretched over the sash frame with more irregularities, a gap will be created at the upper and lower edges of the mesh net, and the insect repellent effect will be reduced. It is also necessary to attach a separate guide rail to the frame. Therefore, providing two roll screen doors on the left and right, or attaching a separate guide rail to the sash frame in order to enhance the insect repellent effect of the mesh screen has the drawback of increasing the product cost.

Generally, in a roll screen door, a storage case for winding and storing the net and a moving rod fixed to one edge of the net pull each other through the net. When the expanded and stretched net receives wind pressure, the excess length of the net remaining on the winding shaft in the storage case is pulled out by the wind pressure and expanded and stretched. The net is curved, and a large gap is generated between the upper and lower edges of the net and the upper and lower frames of the sash, resulting in impaired hermeticity and loss of insect repellent action. Furthermore, since the mesh net is always pulled in the direction of the take-up axis by the torsion spring provided on the take-up shaft, if the moving rod for expanding and stretching the mesh net is tried to be securely fixed, This fixing device becomes complicated and may cause a failure or a product cost.

On the other hand, in the pleat screen door, it is necessary to install a separate frame on the outside of the sash frame, which also has the drawback of increasing the manufacturing cost. However, there is a drawback in that the sealing property of the screen door is likely to be impaired when it is damaged.

Since aluminum structural members are used for the structural members such as the roll screen door, when the roll screen door is attached to the sash frame, the structural members such as the roll screen door and the sash frame and the sash window are installed. There is a problem in that the colors are not the same as those of the members and the like, which is not preferable in terms of appearance design. However, since the manufacturing method and manufacturing process are significantly different between the roll screens and the sash frames, the sash manufacturer outsources the roll screens to a screen door specialist, or purchases the roll screen doors that the screen door manufacturer manufactures independently. It is the actual situation. Since the manufacturers of the roll screen and the sash frame are different in this way, even if the designated color is arranged in advance so that the roll screen and the sash frame have the same color, a subtle color difference cannot be prevented. In some cases, it was necessary to replace the installed roll screen doors or the like due to the difference in color. For this reason, aluminum structural members used for roll screen doors are manufactured by an aluminum sash maker and then distributed to screen door specialists.However, management costs and transportation costs increase as the variety of color types increases. In addition, it was also a cause of delayed delivery.

Therefore, the present invention is intended to improve the problems and drawbacks of the above-mentioned conventional ones, and can sufficiently cope with various kinds of sash frames without lowering the appearance, while reducing the manufacturing cost. The present invention aims to provide a door-plate-shaped storage screen door that can improve versatility.

[0010]

To this end, for example, a door-plate-shaped storage screen door has an upper horizontal frame and a lower horizontal frame having opposed U-shaped sliding grooves, and a vertical frame having storage pockets. And a rectangular screen door frame having a vertical frame with a U-shaped cross section that opens on the side facing the storage pocket, and sliding of the upper and lower horizontal frames of the rectangular screen door frame. A vertical moving rod that is slidable while fitting the upper and lower ends into the groove, and a roll screen door cassette that is removable from the vertical frame of the rectangular screen door frame in its storage pocket. The screen door cassette has one end attached to a take-up shaft which is rotatably held up and down by a bracket and urged in a winding direction by a spring, and the other end to a screen retainer hoop which is detachable in a vertically moving rod. Draw out a mesh net that is joined to each other Net roll formed by winding a resident,
And a storage case that rotatably holds this mesh roll via a bracket, and a roll screen door cassette is stored and fixed in a storage pocket provided in the vertical frame of the rectangular screen door frame. The upper and lower moving rods that are integrated with the above-mentioned mesh retainer hoop are pulled out along the sliding grooves of the upper horizontal frame and the lower horizontal frame that face each other, and the mesh net that forms the mesh roll is pulled out from the mesh roll. It is formed by sliding while being engaged and fixed to the vertical groove in the vertical frame of the door end.

More specifically, the mesh holding hoop joined to the other end of the mesh mesh forming the mesh roll held in the storage case of the roll mesh door cassette has a flat shape in cross section, While forming the jaw part on one end side, the mesh net is joined to the other end side or the other end side by folding back the mesh net, while opening on the side facing the storage case to form the net holding hoop. A lip portion projecting inward is formed on the opening side of the accommodation pocket inside the vertically moving rod to be accommodated, and the mesh holding hoop is inserted into the accommodation pocket of the vertically moving rod and at the same time with respect to the lip portion. By engaging the jaws of the mesh retainer hoop and bringing the other end of the mesh retainer hoop into contact with the inner wall of the storage pocket by the biasing force in the winding direction of the winding shaft, the mesh retainer hoop is inserted. Me A mesh roll formed by winding a mesh net and a vertically movable rod are integrally and detachably connected to each other. Further, in addition, the mesh roll is engaged with the vertical groove in the vertical frame of the door end. , In a longitudinally moving rod for accommodating a net-pressing hoop having a flat cross section in its accommodation pocket,
A step portion is formed on the same side in the indoor / outdoor direction as the lip portion into which the jaw portion of the mesh holding hoop is fitted, and at the opening side of the vertical groove in the door end vertical frame with which the vertical moving rod engages, the inward direction. A step portion of the vertically movable rod having a meshing hoop accommodated in a storage pocket provided therein, and an engagement protrusion in a vertical groove in the vertical frame of the door end are engaged with each other. By bringing together, the tip end side of the vertical movement rod is brought into contact with the inner wall of the vertical groove in the vertical frame of the door tip by an urging force in the winding direction to the winding shaft via the mesh holding hoop,
The mesh-like mesh can be stretched freely from the mesh roll to the vertical frame of the door end through the mesh retainer hoop and the vertical moving rod.

In addition, a support shaft integrally supporting the take-up shaft at the upper and lower ends of the take-up shaft for winding the mesh net is fixed to brackets fixed to the upper and lower ends of the storage case. In contrast, the mesh net appears or disappears by holding it together with the elastic body in the long hole formed in the direction in which the mesh net appears, or in the storage pocket provided on the vertical frame of the storage case of the roll screen door cassette. It is fixed slidably in the direction, and the rod that can be retracted by elastic body installed in the pusher provided at each end of the upper and lower horizontal frames is brought into contact with the storage case that stores the net roll. By letting
The support shaft or the entire storage case including the support shaft is urged in the direction in which the mesh net is retracted.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION As described above, a roll screen door cassette, which is a separate body, is stored and fixed in a storage pocket provided in the vertical frame of a rectangular screen door frame. Since the upper and lower edges of the net can be expanded and stretched while being housed in the sliding grooves of the upper and lower horizontal frames, the drawbacks of conventional mesh-like nets, which are present in conventional door plate mesh doors, are eliminated. In addition, it facilitates inspection and replacement of the net. In addition, it can be manufactured at a lower cost than conventional roll screens and pleated screens, and the roll screen door cassette is stored in a storage pocket provided in the vertical frame, and the screen retainer hoop is also installed in the vertical movement rod. Therefore, even if a roll screen door cassette is manufactured separately by a screen door specialist, the color difference between the aluminum sash material and the sash frame forming the roll screen door cassette does not pose a problem in appearance. . Furthermore, the upper and lower edges of the mesh net that will be expanded and stretched on the rectangular screen door frame slide on the vertical moving rod and closely contact the inner wall surface in the sliding groove of the lower horizontal frame. Since it is housed while being housed, the insect repellent effect can be enhanced.

In addition, a mesh retainer hoop joined to a mesh mesh forming a mesh roll held in the storage case of the roll mesh door cassette is provided in the winding direction applied to the winding shaft of the mesh roll. Utilizing the urging force, in the accommodation pocket inside the vertically movable rod, by rotating around the engagement point between the jaw of the mesh holding hoop and the lip of the accommodation pocket,
Since it can be fixed by being brought into contact with the inner wall surface of the storage pocket, the mesh holding hoop and the vertically movable rod can be detachably connected with a simple structure. In addition, a vertical moving rod for accommodating the mesh retainer hoop is attached to the winding shaft of the mesh roll in the same manner as described above, centering on the engagement point between the stepped portion and the engagement protrusion in the vertical groove of the door frame vertical frame. It can be fixed by rotating it via the mesh retainer hoop using the biasing force in the winding direction and abutting against the inner wall surface in the vertical groove to fix it. Can be

Further, when the mesh net is first stretched by pressing the support shaft integrally supporting the take-up shaft or the storage case including the support shaft in the direction in which the mesh net is retracted. Even if the size is not enough, the winding shaft of the mesh roll is moved by strongly sliding the vertical movement rod integrated with the mesh roll via the mesh presser hoop, and the vertical movement rod is connected to the vertical frame of the door tip. Can be engaged and fixed. Moreover, the mesh net expanded and stretched on the rectangular screen door frame is urged in the winding direction by the spring with respect to the winding shaft,
Since the mesh-like net is pushed more strongly in the retracting direction with respect to the support shaft or the storage case including the support shaft, the upper and lower edges of the mesh-like net are the sliding grooves of the upper and lower horizontal frames. It adheres strongly to the inside and further enhances the insect repellent effect.

Then, the tip of the vertical movement rod (5) is rotated by the torsion spring to the winding shaft (10). Is rotated in the counterclockwise direction about the engagement point between the stepped portion (34) and the engagement protrusion (7 ″) by the tensile force of the mesh net (11) caused by being biased in the winding direction. However, since the opening width of the vertical groove (7 ') of the door-end vertical frame (7) is narrow, it comes into contact with the inner wall surface of the vertical groove (7'). That is, the vertically movable rod (5) is a mesh holding hoop (12).
Similarly, by utilizing the tensile force of the mesh net (11), the engagement point between the step portion (34) and the engagement protrusion (7 ″), the tip of the vertical movement rod (5) and the vertical groove (7 ′). ), The mesh-like net (11) is wound tightly through the net-pressing hoop (12) and the vertical moving rod (5). The mesh-shaped net (11) can be stretched freely from the net roll (9) to be formed up to the door end vertical frame (7) (see FIG. 2).

Further, the support shaft (13) for axially supporting the take-up shaft (10) for winding the mesh net (11) at the upper and lower ends thereof has a square shaft portion (1) at its end portion.
3 '), and the upper and lower brackets (15) (16) that rotatably hold the winding shaft (10),
The long holes (1
5 ') is bored, and the angular shaft portion (13') is inserted into the elongated hole (15 ') of the mesh net (11) into the net roll (9) by the compression spring (17). It is slidably fitted while being pressed (see FIG. 4).

The upper and lower horizontal frames (3) and (4) of the rectangular screen door frame (2) constituting the door plate-shaped storage screen door (1) are mounted on the sash frame (21) and the lower screen door rail (22). (23) steady rest (24) and sliding shoe (2)
5) is slidably mounted through (see FIG. 5). Therefore, the rectangular screen door frame (2) enables the door plate-shaped storage screen door (1) to be installed at a required position in the sash frame (21). At this time, the polyester tape (18) is provided on the upper and lower edges of the mesh net (11) which is to be expanded and stretched on the rectangular screen door frame (1).
Since the strength of the mesh net is increased, the upper and lower edges (11 ′) and (11 ″) of the mesh net (11) will not be affected by the wind pressure from the out-of-plane direction. The inner wall surfaces of the sliding grooves (3 ′) and (4 ′) in the lower horizontal frames (3) and (4) are in close contact with each other and do not deviate.

Since the door plate-shaped storage screen door (1) according to the embodiment of the present invention has the above-mentioned structure, when the door plate-shaped storage screen door (1) is used, the roll screen door cassette (6) is stored. The vertical moving rod (5) integrally connected to the other end of the net roll (9) held in the case (14) through the net presser hoop (12) joined to the rectangular net door frame (2). A net roll that is rotatably held in the storage case (14) by sliding along the sliding grooves (3 ′) and (4 ′) of the upper and lower horizontal frames (3) and (4). The mesh net (11) is pulled out from (9). Further, the vertical moving rod (5) is slid along the sliding grooves (3 ′) (4 ′) of the upper and lower horizontal frames (3) and (4) to store and fix the storage case (14). This is to reach the inside of the vertical groove (7 ') in the door end vertical frame (7) facing the vertical frame (8). At this time, the vertical moving rod (5) has its upper and lower ends at the upper side, and the sliding grooves (3 ') of the lower horizontal frames (3) and (4).
Since it slides while being fitted in (4 '), it can only slide by the above-mentioned sliding grooves (3') and (4 '), but the vertical direction of the door end vertical frame (7). Within the groove (7 '), there is no restriction due to the sliding grooves (3') and (4 ') of the upper and lower horizontal frames (3) and (4). Then, with respect to the winding shaft (10) of the net roll (9) integrally connected via the net presser hoop (12), a torsion spring (not shown) causes the net roll (9) to wind. Since the mesh-like net (11) is applied with a tensile force because the biasing force is applied, the step portion (34) of the vertical movement rod (5) is connected to the vertical groove (7) of the door end vertical frame (7). Engaging projections (7 ") provided in 7 ')
And the vertical movement rod (5) is engaged with the stepped portion (34).
And the engaging protrusion (7 ") are automatically rotated counterclockwise around the engaging point, and the tip of the vertical moving rod (5) is aligned with the vertical groove (7 ') of the door vertical frame (7). Since it is fixed by abutting against the inner wall surface, it is integrally engaged and fixed in the vertical groove (7 ') in the door frame vertical frame (7). By engaging and fixing the door end vertical frame (7) in the vertical groove (7 ′), the upper and lower edges (11 ′) (11 ″) of the rectangular screen door frame (2) are placed on the upper and lower horizontal frames. (3) The mesh net (1) is housed in the sliding grooves (3 ′) and (4 ′) of (4).
5) can be expanded and stretched to form the door-plate-shaped storage screen door (1) according to the embodiment of the present invention.

At that time, the winding shaft (10) for winding the mesh net (11) is passed through the supporting shaft (13) of the winding shaft (10).
Since the mesh net (11) is slidable while being pushed in the direction in which it enters the net roll (9), there is some error in the dimensions of the mesh net (11), and the square net door frame. Even if the opening width is shorter than the opening width of (2), the compression spring (17) is strongly moved by strongly sliding the vertical movement rod (5).
Is compressed and the winding shaft (10) moves, and the vertical movement rod (5) and the vertical groove (7 ') of the vertical frame (7) of the door can be engaged and fixed. Furthermore, spread over the entire surface of the rectangular screen door frame (2),
The stretched mesh net (11) is pulled by the urging force of a torsion spring (not shown), and the winding shaft (10) is wound by the compression spring (17). Since the mesh net (11) is urged in the direction of immersion into the net roll (9) (that is, the same direction as the direction pulled by the biasing force of the torsion spring), it is expanded and stretched. The mesh-like net (11) present is more strongly strained, and together with the polyester tape (18) attached to the upper and lower edges (11 ') (11 ") of the mesh-like net (11),
It strongly adheres to the inner wall surfaces of the sliding grooves (3 ′) (4 ′) of the lower horizontal frames (3) and (4) to remarkably improve the insect repellent effect of the door-plate-shaped storage screen door (1) according to the embodiment of the present invention. At the same time, the anti-plane pressure resistance can be improved.

The storage case (14) of the roll screen door cassette (6) and the mesh holding hoop (12) joined to the other end of the mesh net (11) are both storage pockets () of the vertical frame (8). 8 ') and the storage pocket (5') of the vertical movement rod (5), respectively, so that the storage case (14) and the mesh holding hoop (12) cannot be seen from the outside. The problem of color difference with the sash frame (21), the rectangular screen frame (2), etc. does not occur. Since the rectangular screen door frame (2) and the roll screen door cassette (6) that can be freely attached to and detached from the vertical frame (8) forming the rectangular screen door frame (2) are separate bodies, the rectangular screen door Retrofitting can be easily performed only by attaching the roll screen door cassette (6) to the frame (2), and replacement and inspection of the screen roll (9) can be easily performed.

When it is not necessary to expand or stretch the mesh net (11) in the door-plate-shaped storage screen door (1) according to the embodiment of the present invention, the door end vertical frame (7) is While rotating the vertical moving rod (5) that is engaged and fixed in the vertical groove (7 ') counterclockwise, the step (34) of the vertical moving rod (5) and the door tip are rotated. If the vertical groove (7 ') of the vertical frame (7) is disengaged from the engaging protrusion (7 "), then the tensile force of the torsion spring (not shown) against the mesh net (11) causes The vertical moving rod (5) slides toward the storage case (14) along the sliding grooves (3 ′) (4 ′) of the upper and lower horizontal frames (3) and (4) to form a rectangular screen frame (2). ) Expanded and stretched over the entire mesh (1)

6) is formed by pushing the rod (20) in the direction in which the mesh net (11) is retracted into the net roll (9). As a result, even if there is some error in the size of the mesh net (11) and it is shorter than the opening width of the rectangular screen door frame (2), it is possible to strongly slide the vertical moving rod (5). The compression spring (17 ') is compressed and the storage case (14) itself moves, so that the vertical movement rod (5) and the vertical groove (7') of the door frame (7) can be engaged and fixed. Becomes Further, the mesh net (11) which is spread and stretched over the entire surface of the rectangular screen door frame (2) is pulled by an urging force of a torsion spring (not shown) and is wound. The storage case (14) holding the winding shaft (10) is pulled by the compression spring (17 ') in the direction in which the mesh net (11) is retracted into the net roll (9) (that is, pulled by the biasing force of the torsion spring). (The same direction as the specified direction)
Since the mesh net (11) is expanded and stretched, the mesh net (11) is further strongly tensioned, and the mesh net (11) has upper and lower edges (11 ') (11 "). Together with the attached polyester tape (18),
It strongly adheres to the inner wall surfaces of the sliding grooves (3 ′) and (4 ′) of the upper and lower horizontal frames (3) and (4), and remarkably exhibits the insect repellent action of the door-plate-shaped storage screen door (1) according to the embodiment of the present invention. In addition to the improvement, the anti-plane pressure resistance performance can be improved.
