Description

[Detailed description of the invention] [Field of industrial application] The present invention is a shelf that is relatively light relative to the left and right support members, such as when installing a shelf board between the right side panels of the main body of a tabletop cabinet or letter case. The present invention relates to a shelf support member suitable for mounting.

[Conventional technology and its problems]

When mounting shelves on furniture etc. so that the height can be adjusted, generally, two rows of locking grooves are drilled in the inner surfaces of the left and right side panels of the furniture body, and the shelves are locked in the locking grooves. It is well known that the four corners of the shelf board are supported by support members.

However, if the four corners of the shelf are simply supported from below, the weight of the shelf will be too high, such as a tabletop cabinet used for organizing slips in an office, patient tickets and medical records in a hospital, etc. In the case of lightweight ones, there was a drawback that the shelves could fall off if an object or hand touched the underside of the shelf when taking things in or out. In addition, when simply supporting a shelf board, supports for supporting the shelf board must be provided at two locations on the left and right inside surfaces of the cabinet body, at the front and back, so it is necessary to lock the supports to the cabinet body as well. Since means for this purpose must be provided at two locations, one at the front and one at the rear, there is also a problem in that the structure becomes complicated and manufacturing costs increase.

On the other hand, in Japanese Utility Model Publication No. 51-34419, a pair of upper and lower flanges are provided protruding from a bracket that engages and disengages from the support column, and the back part of the shelf board can be freely inserted between these upper and lower flanges, and the upper and lower flanges are By making the protruding dimension of the upper flange shorter than the protruding dimension of the lower flange, and configuring the shelf so that the upper surface of the shelf comes into contact with the upper flange at a portion closer to the back than the part supported by the lower flange. , a device for supporting a shelf board that horizontally supports the shelf board is disclosed. According to this device, the shelf board can be supported by only supporting the back side of the shelf board in two places, and the cabinet can be easily supported. If applied to shelf support means, the structure can be simplified.

Therefore, in the bracket in this publication, the back side of the shelf board is simply inserted between the upper and lower flanges, and the center of gravity of the shelf board and the abutment part of the upper bracket are placed on opposite sides of the front and back with the support part of the lower bracket sandwiched between them. The shelves are held horizontally by being positioned at The problem was that it could easily fall off.

An object of the present invention is to provide a shelf support member that can stably support a shelf board by only supporting the shelf board at one location at each end on the left and right sides of the shelf board.

[Means for solving problems]

That is, the present invention is a shelf support member for mounting a shelf board having downwardly bent pieces on the left and right side edges between left and right support members such as left and right side boards of a cabinet main body, the shelf support member comprising: , a vertical board disposed along the inner surface of the support member, a lower horizontal piece bent and formed at the upper end of the vertical board to support the lower surface of the shelf board, and a lower horizontal piece in contact with the upper surface of the shelf board. and an upper horizontal piece bent at the upper end of the vertical board so as to be in contact with the support member, and the vertical board is provided with a locking means for non-rotatably locking the support member, while the upper and lower horizontal pieces are formed so as to be shifted in the front-back direction so as not to overlap in a plan view, and a connecting portion for the lower horizontal piece of the vertical board and a connecting portion for the upper horizontal piece are bent downwardly at the connecting portions of the shelf board. It has a structure in which the pieces are separated into two forks when viewed from the front so that they can be held from the inside and outside.

[Functions and effects of the idea]

With this configuration, the lower horizontal piece supports the shelf from below, and the upper horizontal piece comes into contact with the top surface of the shelf to prevent the shelf from rotating. It will be mounted between the left and right support members at the left and right side ends, and the lower vertical piece of the shelf board will be held between the connecting part of the vertical board to the upper horizontal piece and the connecting part of the lower horizontal piece. become.

Therefore, according to the present invention, the shelf board can be mounted between the supporting members by only supporting one location at each of the left and right ends of the shelf board, thereby simplifying the structure for supporting the shelf in a cabinet or the like.

When the shelf board is supported at its left and right ends, if the upper and lower horizontal pieces overlap in plan view, the support point by the lower horizontal piece and the abutment part by the upper support piece will be close to each other. Therefore, the weight of the shelf board acts as a large moment at the contact points with the upper and lower horizontal pieces, making it easy for the shelf board to bend or deform. However, in the present invention, the upper and lower horizontal pieces are shifted in the front-back direction. As a result, the distance between the support part of the shelf board by the lower horizontal piece and the contact part of the shelf board by the upper horizontal part increases, and the weight of the shelf board is applied around the contact part with the upper horizontal part by the principle of leverage. This results in a reduction in the occurrence of large effects, and it is possible to prevent or reduce deflection and deformation of the shelf board.

In addition, since the downwardly bent piece of the shelf board is inserted between the connecting part of the upper horizontal piece and the connecting part of the lower horizontal piece of the vertical board, the shelf board is prevented from shifting in the left and right direction. The stability of the shelf board can be improved.

〔Example〕

Next, an embodiment in which the present invention is applied to a tabletop cabinet will be described based on the drawings.
has a door 2 on the front that can be rotated horizontally,
The cabinet body is made of a thin metal plate in which the front portions of the left and right side plates are formed hollow with an outer plate and an inner plate 3', and the inner plate 3' is folded inward at its front edge into a substantially U-shaped cross section. By bending, the protruding corner parts 4, 4 for reinforcement are formed, and the inner plate 3', which is an example of a support member for supporting the shelf board, is formed on the back side of the protruding corner part 4. , a locking groove hole 5 for locking a shelf support member 6, which will be described in detail later.
are perforated along the vertical direction at a constant pitch P.

Reference numeral 6 indicates a shelf support member for mounting the shelf board 12 having downwardly bent pieces 12' formed on the left and right side edges between the left and right inner plates 3', 3'. The shelf support member 6
The vertical substrate 13 is disposed along the inner plate 3', and the upper and lower horizontal pieces 7 are bent and formed on the upper edge of the vertical substrate 13 so that the upper and lower levels are different.
8, and a locking pawl 10, which is an example of an engaging means for engaging and disengaging from the locking slot 5, is provided on the front edge of the vertical substrate 13, and comes into contact with the rear surface 4' of the protruding corner portion 4. By forming the protrusions 11 in such a manner as to be appropriately spaced vertically, the shelf support member 6 is locked to the inner plate 3' in a state where it cannot be rotated laterally.

At this time, the upper and lower horizontal pieces 7 and 8 are provided by shifting back and forth so that the upper horizontal piece 7 is on the front side and the lower horizontal piece 8 is on the back side, and the upper and lower horizontal pieces 7 and 8 are
The shelf board 1 is inserted between the shelves so that the shelf board 12 can be inserted freely.
2, and the connecting portion 9 of the vertical substrate 13 with the lower horizontal piece 8 is pulled up inside the cabinet body 1 by the dimension S. By separately forming the connecting portion 9 for the lower horizontal piece 8 and the connecting portion for the upper horizontal piece 7 so as to have a bifurcated shape when viewed from the front, the downward vertical piece 1 of the shelf board 12 is connected to both connecting portions.
2' is formed so that it can be held from the front and back.

Note that the front edge of the shelf board 12 is folded back in a substantially U-shape.

In the above configuration, in order to mount the shelf board 12 inside the cabinet main body 1, first, the locking claws 1 of the left and right shelf support members 6, 6, which are formed symmetrically with each other, are
0 into the locking slots 5, respectively, to lock the shelf support members 6, 6 to the inner plate 3',
Next, the shelf board 12 may be placed in a horizontal state or in a diagonally downward position, and its left and right ends may be inserted between the upper and lower horizontal pieces 7 and 8 of the corner shelf support member 6.

In this mounted state, the shelf board 12 is supported by the lower support piece 8 on one side, and a moment of rotation is generated due to its own weight, but its center of gravity is lower than the lower horizontal piece 8. is located on the back side of the cabinet body 1, while the part closer to the front end than the lower support piece 8 is in contact with the upper horizontal piece 7 from above.
The shelf board 12 is held in a horizontal state by being sandwiched from above and below by the upper and lower horizontal pieces 7 and 8.

When the right and left ends of the shelf board 12 are supported, the upper and lower horizontal pieces 7,
8 are overlapped in a plan view, the weight of the shelf board 12 and the load of the articles placed on it will be applied as a large moment to the part of the shelf board 12 where it contacts the upper and lower horizontal pieces 7 and 8 due to the lever principle. However, in the present invention, the upper and lower horizontal pieces 7 and 8 are formed to be shifted in the front-rear direction. Since the distance between the shelf board 12 and the abutting part becomes larger, the influence of the shelf board 12's own weight on the periphery of the clamping part by the upper and lower horizontal pieces 7 and 8 is reduced due to the lever principle, and the shelf board 12 is prevented from bending or deforming. can be prevented or reduced.

In addition, by separately forming the connecting portion for the upper horizontal piece 7 and the connecting portion 9 for the upper horizontal piece 8 in the vertical board 13 into two fork shapes when viewed from the front, the downwardly bent portion of the shelf board 12 can be bent at both connecting portions. Since the shelf board 12' is held between the inside and the outside, the shelf board 12 is prevented from shifting in the left-right direction, and its stability is improved.

Note that the shelf support member 6 may be secured to the rear end of the cabinet body 1 instead of the front end; however, if it is secured to the front end as in the embodiment, it will not engage with the front end of the shelf board 12. When an upward force is applied from below on the shelf board 12, the upward movement of the shelf board 12 is regulated by the upper horizontal piece 7, so objects and hands do not come into contact with the lower surface of the front end of the shelf board 12 when putting in and taking out documents, etc. Even if you win, shelf board 12
This will surely prevent unexpected rotation.

Further, as a means for unrotatably locking the inner plate 3', locking pawls 10 may be formed at the top and bottom as shown in FIG. 6, but as shown in FIGS. If it is formed, it is not necessary to form the locking pawl 10 in accordance with the drilling pitch P of the locking slot 5, so that the shelf support member 6 can be manufactured more easily. In this case, the entire front end surface of the shelf support member 6 may be brought into contact with the back surface 4' of the projecting corner 4.

Further, although only two upper and lower horizontal pieces 7 and 8 were provided in the front and rear, three or more pieces may be provided with the upper and lower horizontal pieces 7 and 8 shifted from each other in the front-back direction. Furthermore, the forms of the locking means, the vertical substrate, and the upper and lower horizontal pieces are not limited to those in the embodiments, and it goes without saying that they can be modified into various forms. First, it can be applied to general shelf devices that support the left and right end portions of shelf boards.
