Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shelf board mounting device in an assembled shelf.

[Conventional technology]

As is well known, in an assembled shelf made of metal plates, a top plate, a base plate, and an intermediate shelf plate are generally attached via corner posts erected at the four corners.

Japanese Patent Publication No. 41-7628 and Japanese Utility Model Publication No. 49-3244 disclose that the left and right side plates of each corner post are attached to the inside of each corner post as a means of attaching a shelf board through a corner post formed in an L-shaped cross section. Fold it back in the same direction to form an inner plate, place clamping plates in the gap between this side plate and the inner plate, and on the inner surface of the side wall at the corner of the shelf board, and fasten both clamping plates with bolts. Accordingly, they proposed a device in which the side wall of the shelf board and the inner board of the corner post are clamped and fixed.

[Problem that the invention attempts to solve]

With this configuration, the corner of the shelf board can be mounted so as to be surrounded by the side plate of the corner post, and even if the corner post has an L-shaped cross section, the locking member and the locking slot can be attached to the corner post. Since it is not exposed to the outside, it is possible to improve the appearance and use space effectively, but the conventional technology has problems in terms of assembly workability and assembly strength.

In other words, in the above-mentioned conventional technology, the shelf board cannot be temporarily fixed to the corner post, and the shelf board and the pair of clamping pieces must be bolted together while maintaining their height positions. Since the bolts are screwed in within the protruding height of the side wall of the shelf board, the work of installing the shelf board is troublesome, and the bolts are installed at the height of the side wall of the shelf board. Therefore, the pair of clamping pieces could only be fastened together with one bolt, resulting in insufficient mounting strength of the shelf board.

The purpose of the present invention is to make it possible to firmly and easily attach shelf boards and the like.

[Means for solving problems]

In order to achieve this purpose, in the present invention, corner posts with an L-shaped cross section are erected at the four corners, and shelf boards that are rectangular in plan view are arranged in areas surrounded by these corner posts. , an inner plate extending inward at an appropriate interval from each side plate is integrally connected to the side edges of the left and right side plates of the corner post, and is locked to the left and right inner plates at appropriate intervals above and below. A slot is bored, and a side wall is provided near the corner of the shelf plate to contact the outer surface of the inner plate of the corner post, and a pair of left and right sides in an upside-down L-shape consisting of a horizontal arm and a vertical leg are provided. A locking body is disposed such that its horizontal arm runs along the inner surface of the side wall of the shelf board, and its vertical leg runs along the outer surface of each inner board of the corner post, so that each horizontal arm of the locking body The locking members are removably engaged with the side wall, and a pair of upper and lower locking claws protruding from the vertical legs of each locking body are locked in the locking slots of the inner plate, and An insert plate made of a metal plate and bent into a truncated chevron shape is inserted between the side plate and the inner plate, and the insert plate is inserted into the locking pawl inserted into the locking slot. The overlapping portions formed by bending the side edges of the vertical legs of the left and right locking bodies are integrally bolted to the left and right intermediate portions of the insertion plates.

〔Example〕

Next, an embodiment of the present invention will be described based on the drawings. In the drawing, reference numeral 1 indicates an assembly shelf made of metal plate;
The assembly shelf 1 consists of corner posts 6 with an L-shaped cross section installed upright at the four corners, a top plate 2 fixed to the top end of each corner post 6, a base plate 3 fixed to the bottom end of the corner posts 6, and a top plate 3 fixed to the bottom end of each corner post 6. It consists of an intermediate shelf board (not shown) installed between the board 2 and the main board 3.

The side edges of the left and right side plates of the corner post 6 are integrally connected with inner plates 7 that extend parallel to the left and right side plates with an appropriate gap between them, and both inner plates 7 include:
Rectangular locking slots 8 are bored at appropriate pitches P and P in the upper and lower sides, respectively. The top plate 2 and the base plate 3 are attached to the upper and lower ends of each corner pillar 6 by a pair of left and right metal plate locking bodies formed in an inverted L shape, as described in detail below. 4 and an interpolated plate 5 inserted between the side plate and the inner plate 7 of the corner post 6.

Incidentally, since the top plate 2, the base plate 3, and the intermediate shelf board are attached by exactly the same means, the case of attaching the top plate 2 as an example of the shelf board will be described below.

Each of the locking bodies 4 includes a vertical leg 9 extending along the outer surface of the inner plate 7 of the corner post 6, and a horizontal arm 11 extending along the inner surface of the downward side wall 16 of the top plate 2, and has left and right locking bodies. vertical leg 9 in body 4
Overlapping portions 10 are formed by bending the proximal end portions so as to overlap each other, and each overlapping portion 10 is provided with three upper and lower through holes 20 concentrically formed therein. In this case, the abutting portion of the vertical leg 9 with the inner plate 7 has a dimension S shorter than the width of the inner plate 7, and the vertical width h of the horizontal arm 11 is set to the downward side wall of the top plate 2. It is smaller than the vertical width h' of 16.

The vertical leg 9 of the locking body 4 includes:
A pair of upper and lower locking claws 12 are provided outwardly projecting at a vertical interval that is an integral multiple of the upper and lower pitch P of the locking slot 8, and both of these locking claws 12 are inserted into the locking slot 8 of the inner plate 7. On the other hand, a window 13 is bored in at least one place in the horizontal arm 11, and a locking tongue piece 14 extending toward the corner of the top plate 2 is cut and raised outward in the window 13. This locking tongue piece 14 is fitted into an engaging protrusion 18 that bulges inwardly on the downward side wall 16 of the top plate 2. In this case, the lower locking piece 1
4 is formed in a tapered shape so that the vertical width becomes narrower toward the tip.

Reference numeral 15 denotes a flange formed by bending the end of the horizontal arm 11.

Near the corner of the side wall 16 of the top plate 2,
A pull-out window 17 is provided, and the upper locking claw 12 of the locking body 4 is inserted into the inner plate 7 through the pull-out window 17.
It is designed to fit into the locking groove hole 8 at the uppermost stage. Further, the locking protrusion 18 formed on the side wall 16 of the top plate 2 is formed so that the vertical width becomes smaller as it goes toward the corner of the top plate 2, so that the locking tongue piece 14 does not play. I try to fit it in without sticking.

The inserting plate 5 is formed by bending a metal plate into a □crest-shaped cross section, and by orthogonalizing the left and right side plates, the side plate is brought into close contact with the inner surface of the inner plate 7, and Tap holes 20 are bored in the left and right intermediate portions at the same vertical pitch as the through holes 21 of the overlapping portion 10 of the locking body 4. In this case, the thickness of the insert plate 5 is set so that it is supported by the lower locking pawl 12 of the locking body 4, and when in this supported state, each tap hole 20
is each through hole 21 of the overlapping part 10 in the locking body 4
is set to match. In addition, the interpolation plate 5
A notch 19 is formed at the upper corner of the left and right side plates, and the dimension l from the notch 19 to the lower end is
By making the spacing l' between the locking claws 12 on the locking body 4 substantially the same, the upper locking claws 12 on the locking body 4 can fit into the locking slot 8 without being obstructed by the insert plate 5. I try to fit into it.

In the above configuration, in order to attach the top plate 2 to the corner post 6, first align the horizontal arms 11 of the locking body 4 with each side wall 16 near the corner of the top plate 2,
By aligning the locking tongue piece 14 of the horizontal arm 11 with the engagement protrusion 18 of the side wall 16, and hitting the collar 15 from the side to shift the locking body 4 toward the corner of the top plate 2. , the upper locking claw 12 is made to protrude outward from the extraction window 17, and the locking tongue piece 14 is moved to the engagement protrusion 18.
to engage. As a result, both locking bodies 14 are attached to the top plate 2, and the overlapping portions 10 of the vertical legs 9 overlap each other (in the embodiment, the left locking body 4 in FIGS. 2 to 4 is attached first). Then, by attaching the locking body 4 on the right side, the overlapping portions 10 are overlapped with each other).

Next, the left and right sides of the corner post 6 and the inner side plate 7
Insert the insert plate 5 into the gap between the left and right locking bodies 4 while holding the insert plate 5 at a predetermined height position.
The upper and lower locking claws 12 are dropped into the locking slots 8 of the inner plate 7 and engaged. As a result, the insert plate 5 is supported by the lower locking claws 12 and cannot fall, and the top plate 2 is temporarily fixed to the corner post 6. Therefore, the vertical legs 9 of both locking bodies 4
A bolt 22 is screwed into the tap hole 20 of the inserting plate 5 through the through hole 21 of the overlapping part 10, and the inner plate 7 and the side wall 16 of the top plate 2 are integrally sandwiched.

In this way, the top plate 2 can be temporarily fixed to the corner post 6, and the insert plate 5 is locked in a predetermined position so that it cannot fall in the temporarily fixed state. Since the vertical legs 9 of the stopper 4 extend below the top plate 2 and the bolts 22 can be easily screwed in, the assembly shelf 1 can be easily assembled. Further, since the vertical legs 9 of the locking body 4 extend downward and the locking body 4 and the insert plate 5 can be fastened together with a plurality of bolts 22, the inner plate 7 and the side wall 16 of the top plate 2 can be fastened together. The tightening force can be increased, and the top plate 2 can be firmly fixed to the corner post 6.

Note that the upper locking claw 12 of the upper and lower locking claws 12 provided on the locking body 4 may be positioned below the lower end surface of the horizontal arm 11, and in this case, the top plate 2
The opening 17 in the side wall 16 becomes unnecessary. Further, as in the embodiment, when the locking tongue piece 14 of the locking body 4 is extended toward the corner of the top plate 2 and engaged with the engagement protrusion 18 of the top plate 2, the bolt 22 is Since the top plate 2 is pulled by the corner post 6 as it is screwed in,
This has the advantage of further improving the mounting strength.

The above explanation has been given for the case where the top plate 2 is attached to the upper end of the corner post 6, but it goes without saying that the attachment of other shelves such as the base plate 3 or the intermediate shelf plates can also be carried out in exactly the same manner as described above.

[Functions and effects of the idea]

The present invention is constructed as described above, and in order to attach the shelf board to the corner post, each of the left and right locking bodies is locked to the inner surface of the side wall near the corner of the shelf board, and the vertical legs of the locking bodies are are placed one on top of the other, and the locking pawl formed on the vertical leg of the locking body is dropped into the locking slot of the inner plate of the corner post to engage, and then the locking claw is inserted into the gap between the left and right side plates and the inner plate of the corner post. Insert the inner plate, and while maintaining its height position, engage the locking pawl of the locking body with the locking slot of the inner plate. This results in
The shelf board is temporarily fixed to the corner post, and the insert board is held at a predetermined height position so that it cannot fall. The inside plate will be stuck. Therefore, if the vertical legs, overlapping parts, and insert plates of both left and right locking bodies are integrally bolted together, the side wall of the shelf board and the inner board of the corner post will be sandwiched, and the shelf board will be attached to the corner post. It will be done.

Therefore, according to the present invention, the shelf board can be temporarily fixed to the corner post, the insert board is supported at a predetermined position in the temporarily fixed state so that it cannot fall, and the vertical legs of the locking body are fixed to the shelf. Since the bolts extend below the plate and can be easily fastened with bolts, the assembly shelf can be easily assembled.

In addition, since the vertical legs of the locking body extend downward, the locking body and the insert plate can be fastened together with multiple bolts, and the horizontal arms of the locking body extend long. Since the contact area between the shelf board and the side wall of the shelf board can be increased, it also has the effect of firmly fixing the shelf board to the corner post.
