Description

[Detailed Description of the Invention] The present invention relates to the structure of a mounting device for a top plate or a bottom plate in an assembled shelf.

When attaching the top plate or base plate of a metal plate assembly shelf to the corner posts of the shelf without using bolts or screws, attach both left and right horizontal arms of the T-shaped locking body to the corner of the top plate or base plate. While in contact with the inner surface of the side plate, the vertical leg of the T-shaped locking body having an L-shaped cross section is fitted into a pair of locking pawls formed on the inner surface of the corner post, which also has an L-shaped cross section, and is locked. There was one that did this (Utility Model Publication No. 50-6903). However, in this case, the locking body becomes bulky when being transported or packaged. In order to solve this problem, a device was devised in which the top plate, etc. could be attached to the corner pillars via a pair of left and right flat locking bodies in an upside-down L-shape (Utility Model Publication No. 56-8509);
Both this and the prior art mentioned above are installed with the vertical side plates of the top or bottom plate sandwiched between the locking body and the corner post, so during the assembly process, the locking body and There was a drawback that the mounting condition with the top plate etc. was unstable. The present invention is an improvement on the above-mentioned prior art, and allows the locking body to be firmly attached to the top plate or the bottom plate in advance, and also prevents the locking body from becoming bulky when disassembled.

Next, the present invention will be explained based on illustrated embodiments.
1 is configured such that each corner of a top plate 2 and a base plate 3, which are rectangular in plan view, are detachably attached to each corner post 6 via a pair of left and right locking bodies 4, 4, each having an upside-down L-shape. This is an assembly shelf made of metal plates.

The base 6' of each corner post 6 is formed into a W-shaped cross section by bending the corner angles of left and right outer plates disposed at right angles to each other by 90 degrees, and the left and right ends of the base 6' are L. The inner plate portions 7, 7 are bent inward in a letter shape, respectively.
A U-shaped locking groove 8 is formed at an appropriate pitch P in both inner side plate portions 7, 7, respectively.

In addition, at the upper and lower parts of the W-shaped cross-sectional base 6' of each corner post 6, there is provided an appropriate space l at the upper and lower corners of the base 6' at locations corresponding to the attachment points of the top plate 2 and the base plate 3. After making two horizontal cutting lines separated by ₁ , a pair of sheath-like locking parts 9, 9, which open vertically and are formed by bulging in the direction of the inner surface of the base, are spaced vertically by an appropriate distance l ₂ . establish. Therefore, the vertical opening in each locking portion 9 is formed in a W-shape in plan view.

The top plate 2 and the base plate 3 each have a rectangular shape in plan view,
The vertical side plate 10 is bent downward around the vertical side plate 10,
10, and the corner portions at the ends of both vertical side plates 10, 10 form cutout openings 11 for attaching and detaching a pair of left and right locking bodies 4, 4, which will be described later, to the top plate 2, etc. It has been done. In addition, both the vertical side plates 1
0 and 10 are provided with a pair of left and right vertical cutting lines, and a pair of left and right sheath-like locking parts 12 and 12 are formed by bulging inward of the vertical side plate 10 between the two cutting lines.
spaced apart by an appropriate distance of l ₃ . The horizontal sheath-like locking parts 12, 12 are formed to be narrower in the upper and lower directions as they move away from the corners of the top plate 2, etc. (inward), and the gap with the inner surface of the vertical side plate 10 is narrower. Form it so that it becomes smaller.

The locking bodies 4, 4 used as a pair of left and right are the vertical legs 1.
3 and a horizontal arm 14, with an upside-down L-shape and left-right symmetrical shape, and both vertical legs 13, 13 are formed in a U-shape in cross section so that they can come into contact with the inner surface of the base 6', which has a W-shaped cross section. A horizontal arm 14, which is integrally extended by bending an upper portion of one side of each vertical leg 13, is formed into a flat shape so as to be able to contact the inner surface of the vertical side plate 10 of the top plate or the bottom plate.

Each of the horizontal arms 14 has the top plate 2 or the bottom plate 3.
Horizontal tongue pieces 15, 15 which can be engaged with the pair of left and right transverse sheath-like locking parts 12, 12 are provided so that their free ends face in the same direction as the free ends of each horizontal arm 14. Further, each tongue piece 15 is formed into a tapered shape so as to become narrower toward the free end. At this time, in this embodiment, one tongue piece 15 is provided to protrude into a slot 16 bored in the middle of the horizontal arm 14, and the other tongue piece 15 is provided to protrude from the free end of the horizontal arm 14. However, both tongue pieces 1
Both 5 and 15 may be provided so as to protrude into the opening 16.

A pair of upper and lower downward locking claws 17 are provided at the midway point in the vertical direction and at the lower end of each vertical leg 13, and are capable of being dropped and locked into the pair of upper and lower sheath-shaped locking portions 9, 9 of the base portion 6'. 17 are provided spaced apart by a dimension l ₂ . At this time, the upper downward locking pawl 17 is formed by cutting out one side of the vertical leg 13 opposite to the protrusion of the horizontal arm 14 in an L-shape.

Note that the mounting brackets 18 shown in FIG.
has a cross-sectional shape that can come into contact with the left and right inner plates 7, 7 of the corner post 6, and a pair of left and right downward hook-shaped locking claws 19, 19 are cut and formed on the outer surface thereof. The locking claws 19, 19 are dropped into the left and right locking grooves 8, 8 in the corner post 6 and are locked therein, while a pair of left and right upward locking claws 20,
20 is bent and formed, and both upward locking claws 20,
20 is inserted into the lower surface groove 21 of the intermediate shelf board 5 to support the intermediate shelf board 5 (see FIGS. 6 and 7).

With this configuration, for example, in order to attach the top plate 2 to the corner post 6, as shown by the arrow in FIG. 11 along the inner surface of the vertical side plate 10, and each horizontal tongue piece 15 provided on the horizontal arm 14 is inserted into the horizontal single sheath-like locking part 12, each locking body 4 will have its vertical leg 13 on the top. It can be locked while protruding downward from the two corners of the plate. In this state, the upper and lower locking claws 17, 17 of both the left and right vertical legs 13, 13,
Since the lower downward locking claws 17, 17 are respectively arranged in a W-shape in plan view, these are connected to the upper and lower opening W-shaped locking portions 9, 9 in plan view of the corner post 6.
It would be better to include each of them.

In this way, the present invention is designed to removably attach a rectangular top plate or base plate in a plan view to the inside of the base of a corner post of an assembly shelf with a W-shaped cross section via a pair of left and right locking bodies in an upside-down L-shape. A flat horizontal arm extends along the inside of the vertical side plate of the top plate or the bottom plate at the top of the vertical leg having a U-shaped cross section of each of the locking bodies, and each horizontal arm has a flat horizontal arm attached to the top plate or the bottom plate. Since we have provided a tongue piece that can be locked on the inside of the vertical side plate when it is inserted into the inside of the vertical side plate from the corner notch opening of the base plate, both the left and right locking bodies can be installed separately on the top plate etc. in advance, and the attached state The locking body is strong and does not wobble vertically against the top plate, etc. A pair of upper and lower locking portions are formed at the base of the corner pillar and have a W-shape in plan view and are bulged inward and open in the vertical direction. Since a pair of upper and lower downward locking claws are provided that can be dropped and locked into both W-shaped locking parts when viewed from above, it is only necessary to attach the locking body, which has been previously attached to the top plate, etc., to the corner post. ,
Assembly work is also extremely easy. Furthermore, since each locking body has an upside-down L-shape and is flat, it does not take up much bulk when being transported or packaged during disassembly. In addition, the horizontal arms of each locking body are locked to the inside of the vertical side panels such as the top plate, and the vertical legs are locked to the inside of the base of the corner pillars, so there is nothing protruding outside during assembly, which improves the appearance of the assembled shelf. It has an effect that can be
