Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for attaching a cover plate to furniture.

[Problems that conventional technologies and ideas try to solve]

In office furniture, etc., the framework of the furniture body is constructed from steel plates, etc., and a cover plate made of synthetic resin, etc. is attached to the outer plate.As a means of attaching the cover plate, conventionally,
The cover plate is screwed to the outer plate, or a through hole is bored in the outer plate of the furniture, and a hook-shaped locking body is protruded from the back of the cover plate, and this hook-shaped lock is used. The body is dropped into the hole and engaged.

However, while the former method of screwing has the advantage of being able to be installed without wobbling, it is difficult to screw in and has poor workability, and it also has problems in that the screw head is exposed to the outside and the appearance deteriorates. Ta.
On the other hand, with the latter attachment means using a hook-shaped locking body, the locking body can be installed by simply inserting the locking body into the through hole and then sliding the cover plate, so the installation work can be performed extremely easily. In order to easily insert the locking body into the through-hole, the width of the locking body must be made smaller than the width of the through-hole, which poses a problem in that the cover plate shakes after installation.

In this invention, the cover plate is attached to the outer panel of the furniture.
The purpose of this is to enable one-touch installation without wobbling.

[Means to solve the problem]

In order to achieve this objective, in the present invention, a through hole is bored in the outer panel of the furniture, and a hook-shaped hook is provided on the back side of the cover plate attached to the surface of the outer panel to be inserted and locked into the through hole. A locking body is provided protrudingly, and the contact surfaces between the base of the locking body and the through hole are each formed in a V-shape,
Further, one of the locking body and the outer surface plate has an engagement protrusion, and the other has an engagement hole into which the engagement protrusion fits when the locking body is locked in the through hole. It has a perforated structure.

[Operations and effects of the invention] In this configuration, in order to attach the cover plate to the outer surface plate, insert the locking body into the through hole, and then hold the cover plate until the locking body comes into contact with the inner surface of the through hole. All you have to do is slide it, and in that state, the outer plate will be held between the locking body and the cover plate, and
Engagement protrusions formed on the locking body and the outer plate fit into the engagement holes, and the cover plate is irremovably attached to the outer plate.

In that case, since the contact surface between the base of the locking body and the through hole is formed in a V-shape, even if the width of the locking body is smaller than the width of the through hole, the cover plate can be slid. Accordingly, the locking body is accurately positioned by receiving a guiding action with respect to the through hole, and since the locking body is engaged with the outer plate in the positioned state, the cover plate can be There is no wobbling in the direction.

Therefore, according to the present invention, even if the width of the locking body is smaller than the width of the through hole, it is possible to prevent the locking body from shifting within the through hole, so that the cover plate can be attached with one touch. Moreover, it has the effect of being able to be installed without wobbling or deteriorating the appearance.

In addition, by forming the base of the locking body in a V-shape, the rigidity of the locking body is improved, so that the locking body can be molded integrally with the cover plate and the locking body from synthetic resin. Even when the stopper is formed relatively thin, it has the effect of reliably preventing the stopper from being damaged or deformed.

〔Example〕

Next, an embodiment in which the present invention is applied to a side cover of a wiring box in a desk will be explained based on the drawings.
It shows a double-barreled steel desk that connects the left and right sides.
Each of the top plates 2 is supported by legs 3 erected on both left and right sides and a sleeve cabinet 4 installed in the center, and between the backs of the left and right legs 3 and the backs of the sleeve cabinets 4, there are A rear curtain plate 5 is installed, and a rectangular parallelepiped-shaped wiring box 6 is installed on the back side of each rear curtain plate 5.
It is attached so that its upper surface is flush with the upper surface of the top plate 2.

The rear curtain plate 5 is attached so that a gap of an appropriate size (H) is created between its upper end and the top plate 2, and the cord A can be freely drawn out into and out of the desk 1 through the gap. In addition, a receiving gutter 7 having a U-shaped cross section is detachably attached to the upper front surface of the rear curtain plate 5. The receiving gutter 7 is attached by locking an upward hook 8 provided on the back side of the gutter to a locking portion 9 of the rear curtain plate 5, and also has hooks on both front and rear edges of the receiving gutter 6. In this method, flexible fin pieces 10 and 11 made of synthetic resin or the like are provided so as to project upward so that their upper ends are in contact with the lower surface of the top plate 2, and these fin pieces 10 and 11 are deformed to receive the code A. He is trying to insert it into the front or back of the gutter 6.

The wiring box 6 has its top and back surfaces largely open, and has a top cover 12 and a back cover 13 removably attached thereto, and a side cover 14 made of synthetic resin is attached to the outer surface of its side plate 6c. On the other hand, on the back side of the front plate 6a, there are multiple shelves 15 for storing various cords A and various devices, and furthermore, on the lower surface of both left and right ends of the wiring box 6, there are pipe-shaped legs with adjuster stars 17. Pillar 1
6 is fixed.

The wiring box 6 has an engaging hook 19 protruding forward from holes 18 bored at both left and right ends of the front plate 6a, and the tip of the engaging hook 19 is inserted into the rear curtain plate 5 of the desk 1. By locking the upper end and pulling the engaging hook 19 into the wiring box 6 by screwing in the screw 20 screwed into the base end of the engaging hook 19, the wiring box 6 is brought into close contact with the desk 1. It can be installed by

In addition, the code|symbol 21 is a reinforcing plate, and the 4th -
Reference numeral 22 shown in FIG. 5 is a cushion material attached to the front surface of the wiring box 6, and this cushion material 22 is brought into contact with the back surface of the leg body 3 or the back surface of the sleeve cabinet 4.

The inside of the pillar 16 and the inside of the wiring box 6 are as follows:
Cap 2 drilled into the bottom plate 6c of the wiring box 6
A vertical groove 25 is cut out on one side of the pillar 16 and is closed with a removable lid 26, and a cord is inserted at the lower end of the lid 26. Edge members 2 are installed in 27 holes.
8, and a cap 29 is attached to the edge member 28 so as to be freely inserted and removed, so that the cord A rising from the floor can be inserted into the wiring box 6 from the inside of the pillar 16.

In addition, grooves for cord insertion are cut in both end edges of each of the upper covers 12, and edge caps 30 made of synthetic resin are attached.

A U-shaped cutout groove 31 is cut out in the upper part of the side plate 6b of the wiring box 6, and a V-shaped lower surface 32a is formed in the upper and lower intermediate parts and the lower part of the side plate 6b. Drilling a hole 32,
Further, an engaging protrusion 33 is formed by cutting and raising the engaging protrusion 33 inward slightly below each through hole 32 .

On the other hand, on the back surface of the side cover 14, a downward hook-shaped locking body 34 is provided protruding from the upper and lower middle portions and the lower portion thereof, and the locking body 34 is inserted into the through hole 32 of the side plate 6b and is locked. By forming the base portion 34a of the locking body 34 into a V-shape when viewed from the back side of the side cover 14, the base portion 34a
a is in close contact with the lower surface 32a of the through hole 32, and the vertical piece 34b of the locking body 34 is configured to fit into the engaging protrusion 32 when the locking body 34 is locked in the through hole 32. An engagement hole 35 is bored.

Further, a vertical upward open groove 36 is cut and formed in the upper part of the side cover 14, and engaging protrusions 37 are formed on both inner surfaces of the upward open groove 36, and a pair of upper and lower side caps 38, 39, the cord A can be inserted from the side of the wiring box 6. In this case, by forming a notch 39a on the outer surface of the upper end of the lower side cap 39, it is possible to hook the upper side cap 38 with a finger and pull it up. By stopping the groove 30a halfway, the lower side cap 30 is prevented from falling even after being removed.

In the above configuration, the side cover 14 is connected to the side plate 6.
To attach the locking body 34 to the side plate 6b, insert the locking body 34 into each through hole 32, and then slide the side cover 14 downward while keeping it in close contact with the side plate 6b, so that the base 34a of the locking body 34 The engagement protrusion 33 fits into the engagement hole 35 while in contact with the lower surface of the through hole 32,
The side cover 14 is attached so that it cannot be removed.

At this time, since the bottom surface of the base 34a of the locking body 34 and the bottom surface of the through hole 32 are each formed in a V-shape, the locking body 34 is tightly fitted to the bottom surface of the through hole 32 by the guide action. However, since the locking body 34 does not shift in the front-rear direction, even if the width dimension (l1) of the locking body 34 is smaller than the width dimension (l2) of the through hole 32, in other words, Even if the locking body 34 is easily inserted into the through hole 32,
The side cover 34 can be attached to the side plate 6b without wobbling.

Further, when the side cover 14 is integrally molded with synthetic resin, the wall thickness of the locking body 34 must be made thin due to the need for die cutting after molding, but the base portion 34a of the locking body 34 is Since the shape improves the rigidity against bending force, even if the locking body 34 is formed thin,
Damage or deformation of the locking body 34 can be reliably prevented. In this case, in order to prevent the side cover 14 from slipping off, an engagement hole 35 is bored in the side plate 6b of the wiring box 6, and the vertical piece 34 of the locking body 34
An engaging protrusion 33 may be provided on b.

When attaching the top cover 12, as shown in FIG. 10, the front and rear support pieces 40 of the wiring box 6 are tilted upward, and the lower ends 30a of the edge caps 30 of the top cover 14 are fitted therein. In this way, when devices such as OA equipment are placed on the top cover 12, the load can be supported intensively at the base end of the support piece 40, so that the support piece 40 In addition to reducing bending deformation, the edge cap 30 acts as a buffer between the top cover 12 and the support piece 40, so it is also possible to prevent rubbing noise from occurring when the top cover 12 or the support piece 40 bends and deforms.

The above embodiment was applied to a side cover of a wiring box in a desk, but the present invention
Needless to say, this method can be applied generally when attaching a cover plate to the surface of furniture.
