Description

[Detailed Description of the Invention] This invention relates to a drawer for furniture used in desks, chests of drawers, cabinets, etc.

BACKGROUND OF THE INVENTION Conventionally, assembling drawers have been known in which the parts of the drawer can be stored and transported in a disassembled state, and then assembled and used as necessary when attached to furniture. For example, Utility Model Publication No. 52-46270,
This is as seen in Utility Model Publication No. 54-2184, Utility Model Publication No. 53-21301, etc. This kind of assembly-type drawer is also advantageous in that it is possible to construct a set of drawers of various sizes by using some of the parts in common and replacing other parts. be. For example, by using the same front and rear panels and replacing the left and right side panels and bottom plate, drawers of various lengths can be made, which is advantageous in terms of parts manufacturing and management costs.

However, in conventional assembly-type drawers of this type, in addition to the essential components of the front and rear panels, left and right panels, and the bottom panel, separate joining parts for assembly are required, which is difficult to manage. In addition, the assembly operation is generally relatively cumbersome, and there are some concerns about its robustness in the assembled state.Furthermore, in order to make assembly possible, the front panel is often made of synthetic resin. This requires a separate decorative mirror panel or wooden decorative panel for the front panel, which not only requires time and effort to install, but also increases the number of parts, leading to increased costs. The dot was hot.

This idea solves the problems mentioned above, that is, the five front and rear, left and right four face plates and the bottom plate.
By combining the dotted parts, it is possible to construct a set that can be assembled freely, and the assembly operation is extremely simple. Moreover, the front panel itself can be constructed from a single wooden board. The object of the present invention is to provide an assembly type drawer with a simple structure.

The structure of this invention will be explained below with reference to the illustrated embodiment.

Reference numeral 1 denotes a front plate made of a wood board, 2 a rear plate made of synthetic resin, 3 and 4 left and right side plates also made of synthetic resin, and 5 a bottom plate made of plywood or the like.

Then, by fitting the peripheral edge of the bottom plate 5 into the groove 6 provided continuously at the lower part of the inner surface of each of the face plates 1, 2, 3, and 4, the adjacent face plates are joined to each other. , the whole can be constructed into an integrated drawer.

Therefore, the joining structure will be explained as follows.

First, the front plate 1 and the left and right side plates 3 and 4 are attached to synthetic resin fastening bodies 8 fixed to the inner surfaces of both ends of the front plate 1 with mounting screws 7. , 4, by forcibly fitting the engagement holes 9 provided in the outer bent edges 3a, 4a of the front ends of the fastening body 8, which is divided into at least two halves, into a tapered engagement shape. The circumferential edge of the engagement hole 9 is tightly engaged with and joined to an engagement step 11 provided on the outer periphery of the base of the retaining pawl 10 .

More specifically, the locking body 8 has locking claws 10, 10, as shown in detail in FIGS. 2 to 5.
It integrally has a mounting cylinder part 16 with a height slightly lower than the claw in the inner center part, and a mounting screw 7 is attached to this mounting cylinder part.
A pair of upper and lower plates are attached to both ends of the inner surface of the front plate 1 by penetrating them. Therefore, after the fastening body 8 is in the above-mentioned mounting state, the engaging holes 9 formed in the outward bent edges 3a, 4a of the side plates 3, 4 are strongly pressed against it, and the engaging claws 10 are elastically pressed. The bent edges 3a, 4a are bent under the engaging step portion 11 by causing deformation.
By tightly engaging the rear surfaces of the front plate 1 and the left and right side plates 3 and 4, the front plate 1 and the left and right side plates 3, 4 can be joined together inseparably from now on. In order to easily carry out this joining operation, as shown in FIG. It is better to perform the operation.
In this case, as shown in FIG.
Since the elastic deformation of 0 and 10 is performed without being hindered by the screw head 7a, the fitting operation can be performed easily. Therefore, if the mounting screw 7 is tightened again after this fitting and the head 7a is positioned between the tips of the locking claws 10, 10, the inward deflection of the locking claw 10 will be prevented by the head 7a. It is possible to prevent bending and maintain the bonded state reliably.

In addition, the rear plate 2 and the left and right side plates 3, 4 are as follows:
It is joined with the following structure.

That is, as shown in FIGS. 6 to 8, there is a rear stopper 12 formed in an inwardly bent shape at the rear end of the side plates 3, 4, and a rear stopper 12 of the same side plates 3, 4 at a position in front of the rear stopper 12. Between the front stopper 13, which has a substantially triangular cross-section and protrudes inward toward the rear end, which is protruded from the middle of the height of the inner surface,
A pair of upper and lower slit-shaped notches 15 are provided on the rear bent edges 2a at both ends of the rear plate 2, on a pair of locking pieces 14, 14 having an L-shaped cross section and facing each other vertically. 15, the rear bent edge 2 is fitted between the stoppers 12 and 13.
A is placed in a sandwiched state and joined.

In the above, when assembling the drawer, first the rear plate 2 is joined to the left and right side plates 3 and 4, and then the bottom plate 5 is fitted into the groove 6 from the front end side of the side plates 3 and 4 and slid to a predetermined position. , Finally, firmly press the front plate 1 against the front ends of the left and right side plates 3 and 4,
If necessary, it can be assembled by forcibly fitting the fastening body 8 into the engagement hole 9 by tapping.

As mentioned above, this idea is easy to store and transport parts because it is an assembly type, and because some parts are interchangeable, other parts can be used in common, and parts of different lengths and widths can be used. Not only can the ivy drawer be assembled, but in particular, only the five-point members of the front plate 1, the rear plate 2, the left and right side plates 3, 4, and the bottom plate 5, to which the fastening body 8 is attached in advance, can be assembled. By assembling a set, a single drawer that can be assembled can be provided, and there is no need for separate mounting screws or joint parts, which is very advantageous in terms of production management, and it is easy to assemble small parts. There is no fear that assembly will be impossible due to shortage. Furthermore, since the front plate 1 allows the side plates 3 and 4 to be joined by screwing the fixing body 8 thereto, the front plate can be manufactured from a wooden board without any problems. Therefore, it is not necessary to separately attach a decorative plate or mirror plate to the synthetic resin front plate as in the conventional case, and the number of parts can be reduced to simplify the structure and reduce costs. Furthermore, through the above-described assembly operation, it can be assembled extremely easily without any difficulty especially in fitting the bottom plate 5, and in the assembled state, all the joints are sufficiently strong and sturdy. can be configured.
