Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plastic assembly structure having a structure in which a shelf plate and a back plate are assembled between a pair of side plates, such as a cabinet, storage furniture, and a desk.
[0002]
[Prior art]
Conventionally, a plastic cabinet is constituted by members such as a top plate, a bottom plate, a left side plate, a right side plate, a back plate, and a shelf plate, and the cabinet is constituted by assembling the respective members.
[0003]
[Problems to be solved by the invention]
Conventionally, in this type of cabinet, each member is configured separately, and the number of parts for configuring the cabinet is very large, and the number of molding steps and the assembly of the cabinet are complicated It was.
[0004]
For this reason, it may be possible to reduce the number of parts by forming a plurality of members in one piece. For example, when the shelf and back plate constituting the cabinet are formed integrally, the assembly shape is fixed in a substantially vertical direction. Therefore, the member in which the shelf board and the back board are integrally formed becomes very bulky. Furthermore, when the panel-like members arranged in such a vertical direction are integrally formed by a molding method such as blow molding, it is difficult to uniformly form the thickness of the members depending on the shape. There are problems such as reduced moldability.
[0005]
Therefore, the present invention connects the back plate to the shelf plate integrally through a thin hinge , holds the shelf plate between the pair of side plates in an unfolded state, inserts it from the back side , and assembles the hinge. By folding the back plate at a right angle and holding the back plate at a right angle upward with respect to the shelf plate and assembling between the pair of side plates, the exterior body is composed of the pair of side plates and the top plate. be constituted, its exterior body can be easily assembled shelves insert Runode holds the back plate have open at both sides of the front and back in the deployed state, it the shelf plate from the rear side, moreover Runode assembled between shelves assembled pair of after having held in the right angle back plate upward relative to the shelf plate by bending at a right angle to the hinge upwards to the rear plate, the back plate after assembly of the shelves To provide a plastic assembly structure that can be easily assembled. The it is an object of the present invention.
[0006]

[0012]
1 to 6, reference numeral 1 denotes a shelf box. The exterior body 2 of the shelf-equipped box 1 has a form in which the front surface, the back surface, and the bottom surface are opened by the pair of side plates 3 and 3 and the top plate 4. And the upper and lower two shelf boards 5 and 5 are assembled | attached to the exterior body 2, and the back was closed by the back boards 6 and 6 integrally connected with the shelf boards 5 and 5 and the thin hinge mentioned later. A box with shelves is configured. The pair of side plates 3, 3, the top plate 4, the shelf plates 5, 5 and the back plates 6, 6 are made of plastic having a hollow double wall structure.
[0013]
The two upper and lower shelf plates 5 and 5 have the same configuration, and a back plate 6 is integrally connected to the rear end portion of the shelf plate 5 via a thin hinge 7, and in the illustrated embodiment, Is formed with a protrusion 8 that restricts bending of the hinge 7 only to one side with respect to the shelf plate 5.
[0014]
Support shafts 9 are respectively provided at both ends of the shelf plate 5 and the back plate 6, and the recesses 10 are formed in portions corresponding to the shelf plates 5 of the pair of side plates 3 and 3 and the support shaft 9 of the back plate 6. And has a structure in which the shelf board 5 and the back board 6 are assembled to the pair of side plates 3 and 3. The support shafts 9 provided at both ends of the shelf plate 5 and the back plate 6 are provided at least at the hinge side portion of the shelf plate 5 or the back plate 6 and at the portions on the opposite side of the hinge side of the shelf plate 5 and the back plate 6. In the illustrated embodiment, the shelves 5 are provided at the opposite ends of the shelf 5 on the hinge side, at the opposite ends of the back plate 6 on the hinge side, and on the opposite side of the hinge side. , 3 are also formed so as to correspond thereto. On the shelf board 5 of the hollow double wall structure, a concave rib 11 for reinforcement is formed from the back side.
[0015]
The shelf plate 5 and the back plate 6 integrally connected thereto by the thin-walled hinge 7 are blow-molded as shown in FIG. 7, but the thin-walled hinge 7 is compressed by the hinge forming portions of the molds 12 and 12. Formed.
[0016]
In order to assemble the upper and lower shelf plates 5, 5 and the back plate 6 to the exterior body 2 constituted by the pair of side plates 3, 3 and the top plate 4, the back plate 6 is in an unfolded state with respect to the shelf plate 5. The shelf plate 5 is inserted from the back side of the exterior body 2 and the support shaft 9 on the opposite side of the hinge side is fitted into the corresponding recess 10 of the pair of side plates 3 and 3, and then the back plate 6 a corresponding recess 10 of the hinge side of the support shaft 9 a pair of side walls 3, 3 of the back plate 6 to hold the state at right angles upwardly with respect to the shelf plate 5 bent at a right angle to the hinge 7 upwards And the supporting shaft 9 on the opposite side of the hinge side is fitted into the corresponding recesses of the pair of side walls 3 and 3 to complete the assembly. Since the shelf plate 5 is provided with a projection 8 on the hinge side for restricting the hinge 7 to be folded only in one direction with respect to the shelf plate 5, the back plate 6 can be bent opposite to the shelf plate 5. It is regulated and there is no risk of incorrect assembly.
[0017]
In the form shown in FIGS. 8 to 10, the front-rear width of the shelf board 5 and the back board 6 is configured to be the same as the front-rear width of the exterior body 2. Therefore, for example, as shown in FIG. 8 and FIG. 9, except for the uppermost shelf 5, the other shelf 5 is formed to have a wide depth so that the back plate 6 is flush with the uppermost shelf. It is possible to construct a box 1 with shelves that is rich in various forms such as different shelf boards 5 and narrowing the depth into a shelf shape and forming a back plate 6 in a rising shape. In the shelf-equipped box 1 according to this embodiment, the exterior body 2 is constituted by a pair of side walls 3 and 3, a top plate 4 and a bottom plate 13.
[0018]
【The invention's effect】
According the present invention, integrally connected to the back plate on the shelf plate through a thin hinge, assembly is inserted from the rear side holding the shelf board between a pair of side plates of the back plate in the deployed state, and a hinge upwards The exterior body is composed of a pair of side plates and a top plate by folding the back plate at a right angle and holding the back plate at a right angle upward with respect to the shelf plate and assembling between the pair of side plates. also, the exterior body can be easily assembled shelves insert Runode holds the back plate have open at both sides of the front and back in the deployed state, it the shelf plate from the rear side, moreover shelf assembled Runode assembled between side plates assembled pair of after having held in the right angle back plate upward relative to the shelf plate by bending at a right angle to the hinge upwardly after the plate, after assembly of the shelves back plate It is possible to obtain a plastic assembly structure that can be easily That.
