Description

The present invention relates to a structure for removably attaching a shelf to a mounting surface such as a wall surface.

Traditionally, a widely used method for attaching shelves to a wall is to directly fix the shelf to the wall with screws, but this method makes it difficult to clean the bottom (back side) of the shelf and the gap between the shelf and the wall. Particularly in the case of shelves installed at a low position, about knee height, it was necessary to take a posture of bending forward to see the underside.

Therefore, in order to facilitate cleaning of the shelf body and the mounting surface, a structure is used in which the shelf is detachably attached using hooks.

Patent Document 1 includes a hook having a large diameter head and a small diameter shaft, and a guide groove that engages with the shaft of the hook, and the guide groove has an opening at one end and a shaft at the other end. The structure allows the shelf to be slid and removed using the abutting part that the shelf touches and one or more bent parts between the abutting part and the opening, making it difficult to fall even if the shelf is accidentally hit. , and a removable engagement method is disclosed.

Furthermore, in Patent Document 2, after the support body is engaged with a slit opening downward in the back surface of the shelf body, a locking member is provided on the shelf body to prevent the support body from separating from the slit. A method is disclosed that reliably prevents a shelf from falling off even if some unintended force is applied during use.

If a structure is used in which the guide groove formed on the back surface of the shelf engages with the shaft of the hook, the shelf can be attached and removed, but there is no means to suppress the upward movement of the shelf, and the shelf easily lifts up. Therefore, if your hand or foot inadvertently hits the shelf while trying to pick up an item placed on the top of the shelf, the shelf may shake, the item on the shelf may topple or fall, or the shelf itself may be damaged. There were problems such as it coming off and falling.

In the structure described in Patent Document 1, one end of the guide groove having a bent part is opened, and the strength of the engaging part is reduced, so that application to washstands, counters, etc. that are subject to relatively heavy loads can be avoided. There were problems such as:
Furthermore, the guide groove with the bent part requires the shelf to be moved diagonally horizontally when it is installed or removed, and if it is installed close to the corner of the room or if other parts are installed adjacent to the shelf, the installation or removal will not be possible. There were problems such as being unable to do so and limiting the installation location.

In addition, in the structure described in Patent Document 2, a lock member is used to prevent the shelf from falling off, but it is complicated to lock and release the lock member when attaching and detaching, and there is a risk of the shelf falling off due to forgetting to lock it. There was a problem.
Furthermore, the locking member and its surroundings have a complicated and uneven shape, which causes dirt to easily adhere to the locking member, resulting in poor cleaning performance.

The present invention has been made in view of the above-mentioned conventional problems, and allows a shelf to be attached and detached by a simple method while ensuring sufficient attachment strength, and also allows for a shelf to be attached and removed even when unintentional force is applied. To provide a removable shelf mounting structure that does not easily fall off and has excellent shelf cleanability.

The present invention has the following configuration as a means for solving the above problems.
(1) The shelf mounting structure according to the present invention includes a shelf having a plurality of pothole-shaped engagement portions provided on a back plate , and a plurality of locking members fixed to a wall surface, and the shelf has a plurality of locking members fixed to a wall surface. A shelf mounting structure in which the engaging portion is engaged with a locking member so that the shelf can be attached to and detached from a wall surface, the locking member having a head and a shaft portion having a smaller diameter than the head. , a locking member having a through hole penetrating the center portion of the head and the shaft portion, having a fixing member that can be inserted into the through hole and attachable to the wall surface; The end-side pothole provided at the left and right ends has a large diameter part and a small diameter part, and the opening width dimension of the connecting end of the large diameter part and the small diameter part is equal to the shaft part of the locking member . A central pothole hole having a large diameter portion and a small diameter portion is formed between the end pothole holes at the left and right ends of the back plate; The inner diameter of the small diameter portion of the center potbelly hole is larger than the inner diameter of the small diameter portion of the hole, and the connection between the large diameter portion and the small diameter portion of the center potbelly hole is larger than the opening width dimension of the end pothole. It is characterized by an enlarged opening width at the end .

(2) In the shelf mounting structure according to the present invention, the shelf includes a shelf body, a front plate protruding from the front side of the shelf body toward the back side of the shelf body, and the shelf body. The main body includes side plates protruding toward the back side of the shelf body on both side sides, and a back plate protruding toward the back side of the shelf body on the back side of the shelf body, It is characterized in that a plurality of potbellied hole-shaped engaging portions are provided through the back plate .

( 3 ) In the shelf mounting structure according to the present invention, in the shelf mounting structure according to (2) , the side cross section of the shelf is approximately U-shaped, and the shelf is parallel to the thickness direction of the shelf. A length dimension of the front plate parallel to the thickness direction of the shelf is relatively small with respect to a back dimension.

(4) In the shelf mounting structure according to the present invention, in the shelf mounting structure according to any one of (1) to (3), an R-shaped portion is provided on the outer peripheral edge of the back plate that comes into contact with the wall surface. It is characterized by

(5) In the shelf mounting structure according to the present invention, in the shelf mounting structure according to any one of (1) to (4), the rear side of the shelf that contacts the wall surface, The present invention is characterized in that a recessed portion recessed in a direction away from the wall surface is provided at a position surrounding the outer peripheral edge.
(6) In the shelf mounting structure according to the present invention, in the shelf mounting structure according to any one of (1) to (5), the rear surface of the back plate has an intersection angle of more than 90° with respect to the upper surface of the shelf. and a downward slope toward the wall surface is provided to the upper surface of the shelf when the shelf is attached to the wall surface.

According to the present invention, the shelf can be removably attached to the wall surface by engaging the locking member attached to the wall surface with the pothole hole on the back surface of the shelf. In addition, the end-side pothole holes provided at the left and right ends of the shelf have a holding part where the opening width dimension at the connecting end of the large diameter part and the small diameter part is narrower than the outer diameter of the small diameter part, so the size of the potbellied hole is The shelf can be installed by simply aligning the locking member with the diameter part, inserting the shelf, pushing down the shelf, and inserting the shaft of the locking member into the small diameter part of the end-side pothole through the clamping part. is completed.
Since the clamping part prevents the shaft of the locking member inserted into the small diameter part of the end-side potbellied hole from coming off, the locking member is prevented from coming off from the small-diameter part of the end-side potbellied hole, which prevents accidents during use. It is possible to prevent the shelf from easily falling off with a moderate amount of force.

A shelf is constructed by integrating a front plate, a side plate, and a back plate into a shelf body, and the shelf body is reinforced by the front plate, side plates, and back plate, thereby improving the rigidity of the shelf. In this configuration, the potbelly holes formed to penetrate the back plate are opened on the inside of the back plate, but the existence of the potbell holes hardly causes a decrease in the rigidity of the shelf. It is possible to provide a configuration that contributes to suppressing the deformation of.

When securing a wide shelf or mounting strength, it can be handled by providing one or more locking members and an engaging portion in the center. Here, by forming both the small diameter part and the clamping part of the center-side bellows hole larger than the small-diameter part and the clamping part of the end-side bellows hole at the left and right ends, the mounting height and pitch of the locking member can be adjusted slightly. The shelves can be attached and detached by absorbing any misalignment.
By making the inner diameter and opening width of the small diameter part of the center pothole hole larger than the corresponding part of the end pothole hole, either the left or right end pothole hole of the shelf can be engaged with the locking member first. When the remaining bellows holes are engaged with the locking member and the shelf is engaged while being subtly moved diagonally in the vertical, horizontal and horizontal directions, the center-side bellows hole has the effect of having a clearance effect to prevent collisions.

By making the dimension of the back surface parallel to the thickness direction of the shelf larger than the dimension of the front surface in the same direction, it is possible to hide the locking member and the pothole hole with the shelf and make it invisible from diagonally above the front side when in use. It can be used as a shelf without damaging the appearance. Additionally, this configuration allows the area of the back side of the shelf that is in contact with the wall to be increased, which improves the mounting stability of the shelf and prevents the shelf from coming off easily even if an unexpected force is applied to the tip of the shelf. It can be done.
Furthermore, by sloping the top surface of the shelf downward toward the wall, drainage of the top surface of the shelf can be improved, and if you lower your line of sight to approximately the same height as the top surface of the shelf, you can easily see the locking member and the pothole. Since the presence of the pothole can be made visible to the user, the user can be made aware of the release of the locking member through the pothole, and the shelf can be easily attached and detached.

In addition, in order to prevent the shelves from wobbling, etc., when attaching and detaching the shelves, the back of the shelves and the wall are in close contact with each other, so by forming an R-shaped part on the outer periphery of the back, there is no possibility of scratches between the shelves and the wall due to the attaching and detaching operations. The occurrence can be suppressed.

Furthermore, by providing a recess that is recessed in the direction away from the wall surface so as to surround the outer periphery of the pothole, the occurrence of scratches between the outer edge of the engaging part and the wall surface, where stress is most concentrated during attachment/detachment operations, is suppressed. be able to.

Hereinafter, the details of the present invention will be explained by citing embodiments of the present invention.
As shown in FIGS. 1 and 6, the shelf 1 of this embodiment has a locking member 2 fixed to a wall surface 310, and a pothole provided on the back surface 110 of the shelf 1 as shown in FIGS. 2 to 4. By engaging the shaped engagement portion 150, it is detachably attached to the wall surface 310.
In the embodiment shown in the figure, the shelf 1 includes a flat shelf main body 10 that is supported horizontally in a nearly horizontal state, and a front end of the shelf main body 10 that faces downward (the back side of the shelf main body 10 A front plate 11 that is integrally hung down (facing the shelf body 10), a side plate 12 that is integrally hung downward (facing the back side of the shelf body 10) on both sides of the shelf body 10, and a shelf board It consists of a back plate 13 that is integrally extended toward the rear end of the main body 10 facing downward (facing the back side of the shelf main body 10).

The thickness of the front plate 11, the side plate 12, and the back plate 13 are formed to be approximately equal to the thickness of the shelf body 10, and the length of the front plate 11 parallel to the thickness direction (vertical direction) of the shelf body 10 is The length (height) and the length (height) of the side plate 12 are formed to be equal. Further, the length (height) of the back plate 13 parallel to the thickness direction of the shelf body 10 is approximately twice as long (high) as the length (height) of the front plate 11 in the same direction. .

As an example, the shelf 1 is composed of a molded product in which a shelf main body 10, a front plate 11, side plates 12, 12, and a back plate 13 are integrally molded with resin.
The shelf 1 is constructed by integrating the front plate 11, the side plates 12, 12, and the back plate 13 into the shelf body 10, and the shelf body 10 is reinforced by the front plate 11, the side plates 12, 12, and the back plate 13. The rigidity of the shelf 1 is improved by making it a molded product.

The shelf 1 can be removed from the wall surface 310 by disengaging from the potbell-shaped engaging portion 150, so when cleaning the area where the back surface 110 of the shelf 1 and the wall surface 310 are in contact, the shelf 1 must be removed. Can be easily removed and cleaned. In addition, the potbell-shaped engaging portion 150 is opened on the inside of the back plate 13 that constitutes the back surface 110 of the shelf 1, thereby suppressing a decrease in the rigidity of the engaging portion 150 and ensuring the mounting strength of the shelf 1. and deformation can be suppressed.

As shown in FIGS. 2 and 7, the end-side potholes 151 provided at the left and right ends of the back plate 13 consist of a lower large-diameter portion 152 and an upper small-diameter portion 153. Further, a holding part 154 is provided in which the opening width dimension at the connecting end of the large diameter part 152 and the small diameter part 153 of the end-side pothole 151 is narrower than the outer diameter dimension of the small diameter part 153. With this structure, as shown in the order of FIGS. 4(A) to 4(B), the locking member 2 is inserted into the large diameter part 152, the shelf 1 is pushed down, and the small diameter part of the end-side pothole 151 is inserted. 153, the shelf 1 can be detachably attached to the locking member 2.
Note that the width of the holding part 154 is smaller than the outer diameter of the shaft part 220 of the locking member 2, which will be explained below, so that the shaft part 220 is prevented from coming off from the small diameter part 153 during use. It is possible to prevent the shelf 1 from falling off due to careless force during cleaning.

As shown in an enlarged view in FIG. 9, the locking member 2 includes a head 210 and a shaft portion 220 having a smaller diameter than the head 210, and has a through hole 230 passing through the center of the head 210 and the shaft portion 220. Furthermore, it has a fixing member (screw) 240 that is inserted into the through hole 230 and fixed to the wall surface 310.
The outer diameter of the large diameter portion 152 of the end pothole 151 is larger than the outer diameter of the head 210 of the locking member 2, and the outer diameter of the small diameter portion 153 of the end pothole 151 is larger than the outer diameter of the head 210 of the locking member 2. The outer diameter of the shaft portion 220 is smaller than the outer diameter of the shaft portion 220, and larger than the outer diameter of the shaft portion 220.

Further, as shown in FIGS. 2, 3(A), and 7(B), two center-side pothole holes 155 are formed at the widthwise (horizontal) center side of the back plate 13. The end-side pothole holes 151 are formed at both ends of the back plate 13, while the two center-side pothole holes 155 are formed in the back plate 13 so as to be spaced apart from each other. Each potbell hole is formed in the back plate 13 so that the distance between the two center pothole holes 155 and the distance between the end pothole holes 151 adjacent to both sides of the center pothole hole 155 are approximately equal.

The center pothole 155 consists of a large diameter portion 156 and a small diameter portion 157. The inner diameter of the large diameter portion 156 of the center pothole 155 is equal to the inner diameter of the large diameter portion 152 of the end pothole 151, but the inner diameter of the small diameter portion 157 of the center pothole 155 is equal to the inner diameter of the large diameter portion 152 of the end pothole 151. The inner diameter of the small diameter portion 153 of the pothole 151 is made slightly larger. Furthermore, with respect to the opening width dimension H1 of the holding portion 154 formed at the connecting end of the large diameter portion 152 and the small diameter portion 153 of the end pothole 151, the large diameter portion 156 and the small diameter portion 157 of the center pothole 155 are The opening width dimension H2 of the connecting portion is formed slightly larger. As an example, as shown in FIG. 7(B), the opening width dimension H2 of the connecting portion of the central pothole 155 is formed to be the same as the inner diameter of the small diameter portion 157.

In the back plate 13, the four pothole holes 151, 155, 155, 151 are horizontally aligned and formed at approximately the same height position on the back plate 13, but the vertical height positions of the respective parts of these potbelly holes are slightly different.
A common feature of the back plate 13 is that the inner bottoms of the large diameter portions 152, 156, 156, 152 of the four pothole holes 151, 155, 155, 151 are arranged at the same height from the lower end thereof. Since the inner diameters of the large diameter portion 152 of the end pothole 151 and the large diameter portion 156 of the center pothole 155 are the same, the height positions of the large diameter portions of both pothole holes are at the same height relative to the back plate 13. It is located in
However, since the small diameter portion 157 of the center pothole 155 has a larger inner diameter than the small diameter portion 153 of the end pothole 151, the inner diameter of the small diameter portion 157 of the center pothole 155 is larger than that of the small diameter portion 153 of the end pothole 151. A distance H4 from the lower end of the back plate 13 to the inner upper end of the small diameter portion 157 of the center pothole 155 is slightly larger than a distance H3 to the inner upper end of the small diameter portion 153.

By making the inner diameter of the small diameter portion 157 of the center potbelly hole 155 and the opening width dimension H2 of the connecting portion larger than the inner diameter of the corresponding portion of the end potbelly hole 151, the height of the position at which the locking member 2 is attached can be increased. Even if a slight deviation occurs in the pitch, it can be absorbed and the shelf 1 can be easily and reliably attached and detached, and the workability when attaching the shelf 1 can be improved.
Note that the same effect can be obtained by making only the inner diameter of the small diameter portion 157 of the center pothole 155 larger.

In the above configuration, the four pothole holes 151, 155, 155, and 151 formed to penetrate the back plate 13 are opened inside the back plate 13, but the front plate 11 and the side plate 12, 12 and the back plate 13 are integrally molded to form a rigid body, so the presence of the potbellied holes 151, 155, 155, 151 hardly causes a decrease in the rigidity of the shelf 1. Therefore, it is possible to provide a configuration that contributes to securing the mounting strength of the shelf 1 and suppressing deformation of the shelf 1.

Furthermore, as shown in FIG. 10, it is better to move the locking members 2 on either the left or right ends of the shelf 1 as a fulcrum and move the other one upward than to remove the shelf 1 by moving the shelf 1 upward in parallel. force can be reduced.

Furthermore, when the shelf 1 is slightly rotated in the direction shown by the arrow in FIG. Since the shelf 1 can be rotated smoothly, the shelf 1 can be attached and detached smoothly.
That is, by making the inner diameter and opening width of the small diameter portion 157 of the center pothole 155 larger than the corresponding portion of the end pothole 151, the pothole 151 on either the left or right end of the shelf 1 can be opened first. When engaging the locking member 2, engaging the remaining pothole with the locking member, and engaging the shelf 1 while subtly moving diagonally in the up, down, left and right directions, the clearance effect to prevent collision is achieved by using the center side bellows. The hole 155 has the same effect. Furthermore, when the engagement is released, the center pothole 155 also has a clearance effect to prevent contact.

This effect is achieved not only because the outer shape of the small diameter portion 157 of the center pothole 155 is larger than the outer diameter of the small diameter portion 153 of the end pothole 151 as shown in FIG. It is also effective that the distance H4 from the lower end of the back plate 13 to the inner upper end of the small diameter portion 157 of the center side bellows hole 155 is slightly larger than the distance H3 from the inner upper end of the small diameter portion 153 of the side bellows hole 151. Demonstrated.

As shown in FIGS. 2 and 3(B), the top surface 130 of the shelf 1 is directed from the front surface 120 to the back surface 110. In other words, by providing a drainage slope that slopes downward toward the wall surface 310, articles can be prevented from falling toward the user (front surface 120 side), and hot water can be prevented from splashing onto the user.

As shown in FIGS. 1, 2, and 6, by providing a drainage channel 111 on the right end side of the upper surface 130 through which small objects are washed away with hot water or the like and fall, the effect of flowing out small objects can be further enhanced.
The recess 131 is a recess-shaped recess that is approximately rectangular in plan view and is lowered one step lower than the other part of the upper surface 130, and extends from a position slightly further back than the front plate 11 in the shelf main body 10 to the most extreme position of the shelf main body 10. It is formed to reach deep inside. The width of the recess 131 is approximately a fraction of the width of the shelf body 10. A drainage channel 111 is formed by forming a vertical groove on the surface of the back plate 13 so as to be located at the center of the innermost part of the depression 131.
Therefore, the hot water in the depression 131 is guided to the drainage channel 111 by the above-mentioned downward slope, and is quickly discharged from the shelf 1.

As shown in the installation state reference diagram in FIG. 8, the hanging dimension of the front surface 120 is made smaller than the hanging dimension of the back surface 110, so that the user can see the locking member 2 and the Since the engaging portion 150 is not visually observed, the beauty of the shelf 1 is not spoiled from the perspective of normal use.
Further, as shown in FIG. 5, when the user lowers his/her posture and lowers his/her line of sight to approximately the same height as the top surface 130 of the shelf 1, the presence of the locking member 2 and the engaging portion 150 can be visually confirmed through the front plate 11. This makes it possible to easily confirm the mounting/detaching position of the shelf 1.
The reason why the user can visually see the presence of the locking member 2 and the engaging part 150 from a lowered position is that the shelf main body 10 is sloped downward toward the wall surface 310, and the lower end of the front plate 11 is This is because it is arranged slightly above the fixed position of the locking member 2 and the engaging part 150.

As shown in FIG. 8 as an example, the shelf 1 of this embodiment is removably attached to a wall surface 310 above a floor 330 provided in a bathroom 3, slightly above the mounting position of a faucet 340. There is. This mounting position is a position similar to the upper surface position of the bathtub 320 equipped with the apron 350, or a position that can be reached while sitting on the float, and is generally at a height of about 40 to 70 cm from the bathroom floor.
If the shelf 1 is removably installed in this position, in order for the user to remove the shelf 1, it is best if the user is aware of the existence of the pothole holes 151 and 155 and the engagement structure with the locking member 2. However, if the user does not know how to remove the shelf 1, the user needs to look down into the engaging portion 150 to understand how to remove the shelf 1.

Therefore, as shown in FIG. 5, it is necessary to look down near the lower end of the front plate 11 and look into the engaging portion. Here, the shelf board main body 10 is given a downward slope toward the wall surface 310, and when looking at the fixed position of the locking member 2 and the engaging part 150 from the lower end position of the front plate 11, the engaging part 150 is visually observed. What you can do is important. If the shelf 1 is at a height of about 25 cm from the bathroom floor, lowering the line of sight as shown in Figure 5 is the limit for a user of normal height, and it is impossible to lower the line of sight any further. difficult to do.

The state shown in FIG. 3A is what the user sees when viewing the engaging portion 150 from a low line of sight as shown in FIG. 5 . In the state shown in FIG. 3(A), the locking members 2 are individually inserted into the small diameter portions 153, 157, 157, and 153 of the four pothole holes 151, 155, 155, and 151, and the shelf 1 is locked. The user can visually recognize the status.
Although the user cannot directly see the shaft portion 220 of the locking member 2, the user can see through the head portion 210 of the locking member 2 and gradually Since the existence of the narrowing part can be recognized and the large diameter parts 152, 156, 156, 152 of the potbellied holes are larger than the head 210 of the locking member 2, the shelf board 1 can be slid upward. It can be recognized that the shelf board 1 can be removed by moving it.

Therefore, even if the user does not know how to remove the shelf 1, by lowering his/her line of sight as shown in FIG. 5, the user can easily recognize how to remove the shelf 1.
This recognition is possible because the head 210 does not hide the gradually narrowing upper portions of the large diameter portions 152, 156, 156, 152 of the potbellied holes. In order to obtain this effect, the outer diameter of the head 210 is larger than the outer diameter of the small diameter portions 153, 157 of the pothole, but it It is preferable that the size is large enough not to hide the gradually narrowing portion.

The shelf 1 and wall surface 310 are attached and detached by pushing down or pushing up while keeping them in close contact with the wall surface 310, as shown in FIGS. By forming the rounded portion 170 around the entire outer periphery of the back surface 110, it is possible to suppress the occurrence of scratches on the back surface 110 of the shelf 1 due to attachment/detachment operations.
As shown in FIG. 6, it is preferable to form R-shaped portions 170 at both corners of the wall surface 310 in plan view.

Furthermore, as shown in FIGS. 2 and 7, by providing a recess 180 in the back surface 110 that is recessed in a direction away from the wall surface 310 so as to surround the outer periphery of the engaging portion 150, stress is minimized during the attachment/detachment operation. It is possible to suppress the occurrence of scratches between the outer edge of the engaging portion 150 and the wall surface 310, which are concentrated.
For example, when the shelf 1 is repeatedly attached and detached, the head 210 of the locking member 2 repeatedly interferes with the surrounding portions of the pothole holes 151 and 155 to align the shelf 1, but the portion where the head 210 interferes is inside the recess 180, so scratches due to interference are limited to the inside of the recess 180. Therefore, scratches on the back surface 110 side of the shelf 1 are not noticeable.
