Description

[Technical Field]

[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. [Background technology]

[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 the wall.

[0003] BACKGROUND 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. [Prior art documents] [Patent documents]

[Figure 10] 1 is a front view showing a fall-off prevention structure according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0015] An embodiment of the present invention will be described with reference to Figures 1 to 10. In the figures, reference numeral 1 denotes the 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-hung furniture that is supported in a state where it is extended out to the side from a wall W. In constructing the structure, first, a hook 2 having a claw 21 protruding vertically upward is fixed to the wall W by a fastener 22. In this embodiment, as shown in Fig. 1, a hook 2 can be used in which a metal plate is bent to form the claw 21 as an integral part. The fastener 22 can be a pin or screw having a head 23, which can be driven into the wall W to fix 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. Note that 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] This fastener 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 fastener 3 is to be disposed. In this embodiment, this through hole 11 is formed in a rectangular shape.

[0019] In a specific installation method, first, with the back panel 1 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 hanging device 3 is inserted from above between the wall W and the claws 21 to place it (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 hooking work to be performed reliably (see FIG. 6).

[0020] An elastically deformable stopper 4 can be fitted inside this through hole 11. In this embodiment, the stopper 4 can be formed in the shape of a bent plate having a pair of tapered surface portions 42 connected by a connecting portion 43 (see FIG. 7). A specific method for manufacturing the stopper 4 is to extrude PVC (polyvinyl chloride) resin into a desired designed cross-sectional shape, thereby enabling low-cost production. With this configuration, the stopper 4 can be fitted inside the through hole 11 of the back plate 1 in a biased state, making it difficult for the stopper 4 to come off.

[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, thereby preventing 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 with each other, 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-hung furniture from rising up and falling off.

[0024] The present invention is generally configured as described above, but the present invention is by no means 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 integrally molded or formed by joining separate parts, and these remain within the technical scope of the present invention.
