Description

Wall-mounted furniture fall prevention structure

[0001] The present invention relates to an improvement in the support structure of wall-hung furniture, and more specifically to a fall prevention structure for wall-hung furniture that allows the hooks on the wall surface to be seen, improves the workability of the installation process, makes it easy to attach and detach stoppers, and restricts the wall-hung furniture from floating up, thereby reliably preventing it from falling off.

[0002] As is well known, storage furniture designs include not only floor-standing types but also wall-mounted types (wall-mounted furniture) that are supported in a state where they are extended out to the side from a wall.

[0003] 2. Description of the Related Art Conventionally, as a structure for supporting wall-mounted furniture, a structure has been disclosed in which a hook is fixed to a wall surface and the furniture is hung on the hook (see, for example, Patent Document 1).

[0004] However, when installing furniture on a wall, it is necessary to align the hooks fixed to the wall with the fixtures on the furniture, but because the back of the furniture is a blind spot, the installation work inevitably has to be done by feel and intuition, making the installation work tedious.In addition, if the furniture is not properly hooked and the worker lets go, it may fall, damaging the furniture or injuring the worker.

[0005] Additionally, safety measures must be taken to prevent furniture from falling off even if it is subjected to upward lifting forces due to vibrations such as earthquakes. However, hammering pins into the wall after the furniture has been installed is a difficult task and poses a risk of injury.

[0007] The present invention was made in consideration of the above-mentioned problems with conventional support structures for wall-hung furniture, and its purpose is to provide a fall prevention structure for wall-hung furniture that allows the hooks on the wall to be seen, improves the workability of the installation process, makes it easy to attach and detach the stoppers, and restricts the wall-hung furniture from floating up, thereby reliably preventing it from falling.

[0008] The means adopted by the present inventor to solve the above technical problems will be described below with reference to the accompanying drawings.

[0009] That is, the present invention is a fall prevention structure for wall-hung furniture that is supported in a state where it is extended out to the side from a wall W, and includes: a hook 2 having a claw portion 21 protruding vertically upwards fixed to the wall W by a fixing device 22; a hanging device 3 is arranged on the back panel 1 of the wall-hung furniture on the side facing the wall, and this hanging device 3 and the claw portion 21 of the hook 2 can be engaged; a through hole 11 is formed in the back panel 1 near the location where the hanging device 3 is arranged, and an elastically deformable stopper 4 can be fitted inside this through hole 11; When the hanging device 3 and the claw portion 21 of the hook 2 are engaged, the protruding portion 41 of the stopper 4 is inserted into the gap between the head portion 23 of the fixing device 22 and the underside of the through-hole 11 of the back panel 1, thereby restricting the back panel 1 of the wall-hung furniture from rising up and preventing it from falling off. This technical means has been adopted to complete a falling-off prevention structure for wall-hung furniture.

[0010] Furthermore, in order to solve the above-mentioned problems, the present invention can also adopt, in addition to the above-mentioned means, if necessary, a technical means in which the stopper 4 is formed into a bent plate shape in which a pair of tapered, expanding surface portions 42 are connected by a connecting portion 43, so that it can be fitted into the inside of the through hole 11 of the back plate 1 in a biased state.

[0011] Furthermore, in order to solve the above problems, the present invention can also employ, in addition to the above means, a technical means, if necessary, in which an anti-slip portion 44 is formed on the surface of the face portion 42 of the stopper 4, and this anti-slip portion 44 presses against the inner surface of the through hole 11, thereby preventing lateral displacement.

[0012] Furthermore, in order to solve the above problems, the present invention can also adopt, in addition to the above means, a technical means in which a notch 12 is formed around the periphery of the through hole 11 of the back plate 1, and the stopper 4 can be pinched and operated by inserting a fingertip into this notch 12, if necessary.

[0013] In the present invention, a hook with a claw portion protruding vertically upward is fixed to a wall surface, while a hanging device is arranged on the side of the back panel of the wall-hung furniture facing the wall surface so that the hanging device can be engaged with the claw portion of the hook, and a through hole is formed in the back panel so that an elastically deformable stopper can be fitted inside the through hole, and when the hanging device and the claw portion of the hook are engaged, the protruding portion of the stopper is inserted into the gap between the head of the fixing device and the underside of the through hole in the back panel.This makes the hook on the wall visible, improving the ease of installation, and the stopper can be easily attached and detached, preventing the wall-hung furniture from floating up and reliably preventing it from falling off, and therefore has excellent industrial value.

[0015] An embodiment of the present invention will be described with reference to Figures 1 to 10. In the figures, reference numeral 1 denotes a back panel of wall-mounted furniture, reference numeral 2 denotes a hook, reference numeral 3 denotes a hanging device, and reference numeral 4 denotes a stopper.

[0016] The present invention provides a fall prevention structure for wall-mounted furniture that is supported in a state where it is extended out to the side of a wall W. To construct the structure, first, a hook 2 having a claw 21 protruding vertically upward is fixed to the wall W with a fastener 22. In this embodiment, as shown in Figure 1, the hook 2 can be formed by bending a metal plate and forming the claw 21 integrally therewith. The fastener 22 can be a pin or screw having a head 23, which can be driven into the wall W to fasten the hook 2.

[0017] Furthermore, a hanging device 3 is provided on the back panel 1 of the wall-mounted furniture on the side facing the wall. In this embodiment, the hanging device 3 is fixed to a recess formed by hollowing out the surface of the back panel 1 to a predetermined depth. The number of hanging devices 3 provided can be increased or decreased depending on the size and weight of the wall-mounted furniture. The enlarged views of Figures 2 and 3 show the back panel 1 with the hanging device 3 fixed thereto as seen from the side facing the wall, while the enlarged view of Figure 4 shows the back panel 1 as seen through the back panel 1 toward the wall W. In this embodiment, the hanging device 3 is a longitudinal metal plate whose main body is bent into a predetermined shape so that it is positioned in the gap between the back panel 1 and the wall W without interfering with the gap, and can be fixed to the back panel 1 with fasteners 31 such as pins or screws.

[0018] The hook 3 can be engaged with the claw portion 21 of the hook 2. A through hole 11 is formed in the back panel 1 near the location where the hook 3 is to be disposed. In this embodiment, the through hole 11 is formed in a rectangular shape.

[0019] In a specific installation method, first, the back panel 1 is lifted up, the through-holes 11 are aligned with the hooks 2, the back panel 1 is brought close to the wall W, and the hooks 3 are inserted from above between the wall W and the claws 21 to place the back panel 1 (see FIG. 5). At this time, the position of the fasteners 22 fixed to the wall W can be visually checked through the through-holes 11, allowing the fastening work to be carried out reliably (see FIG. 6).

[0020] An elastically deformable stopper 4 can be fitted into the through hole 11. In this embodiment, the stopper 4 can be formed in a folded plate shape with a pair of tapered, expanding surfaces 42 connected by a connecting portion 43 (see FIG. 7). The stopper 4 can be manufactured at low cost by extrusion molding PVC (polyvinyl chloride) resin into the desired cross-sectional shape. This configuration allows the stopper 4 to be fitted into the through hole 11 of the back panel 1 in a biased state, making it difficult for the stopper 4 to come loose.

[0021] Furthermore, in this embodiment, a non-slip portion 44 can be formed on the surface of the face portion 42 of the stopper 4, and this non-slip portion 44 is pressed against the inner surface of the through-hole 11 to prevent lateral displacement. For example, a protrusion or an adhesive sheet can be used as the non-slip portion 44, but in this embodiment, a convex strip can be formed in a direction perpendicular to the insertion / removal direction, and further, the cross-sectional shape of this convex strip can be made tapered so that it is easy to insert in the insertion direction and difficult to remove in the removal direction.

[0022] Furthermore, in this embodiment, a notch 12 is formed around the periphery of the through hole 11 of the back panel 1, so that the stopper 4 can be pinched and operated by inserting the fingertips into this notch 12, thereby improving the workability of attaching and detaching the stopper 4.

[0023] 8, when the hanging device 3 and the claw portion 21 of the hook 2 are engaged, the protrusion 41 of the stopper 4 is inserted into the gap between the head 23 of the fixing device 22 and the underside of the through-hole 11 of the back panel 1 (see FIGS. 9 and 10). With this configuration, the presence of the protrusion 41 prevents the back panel of the wall-mounted furniture from rising up and falling off.

[0024] The present invention is generally configured as described above, but is in no way limited to the illustrated embodiment, and various modifications are possible within the scope of the claims. For example, the shapes and materials used of the hook 2, the latch 3, and the stopper 4 can be modified as appropriate, and they may be molded as a single piece or formed by joining separate parts, and these remain within the technical scope of the present invention.
