FIG. 1 is a cross-sectional view of a main part of a shelf device to which a shelf board support structure according to this embodiment is applied. In this figure, a shelf device 10 includes a pair of left and right side plates 11 and 11 arranged in parallel with each other, and the side plates 1.
It is configured by including a shelf plate 12 laid between the two in a substantially horizontal posture, a back plate 13 arranged between the rear ends of the side plates 11 and 11, and a base (not shown).

On the inner surface side of the side plate 11, there are formed recesses 15 as engaging parts at predetermined intervals along the vertical direction. By engaging the recesses 15 with the shelf plate 12 side, the shelves are closed. The board 12 can be bridged.

The shelf plate 12 is formed of a steel material as a molding material. As shown in an inverted state in FIG. 2, the shelf plate 12 includes a mounting surface portion 20 having a substantially rectangular shape in plan view,
A front end face 21 and a rear end face 22 which are located in substantially vertical planes from both front and rear ends of the mounting surface portion 20, and each of the front and rear end faces 2
Reinforcing surfaces 21A and 22A that are bent inward from the lower ends (upper ends in FIG. 2) of 1, 22 and a total of four holding cylinders 24 formed on the lower surface of the mounting surface portion 20 are configured. There is. The holding cylinders 24 are arranged in two rows in a straight line along the left-right direction at two positions in the front and rear of the mounting surface section 20, and a space between the holding cylinders 24 in each row is a shaft member described later. It is configured as an operation fee 26 of. The left-right width of the shelf plate 12 is set to be slightly smaller than the inner dimension between the side plates 11, and when the shelf plate 12 is laid between the side plates 11, the side end surface of the shelf plate 12 is It is provided so that there is almost no gap between it and the inner surface of the side plate 11.

As shown in FIG. 1, a shaft member 30 is inserted into the holding cylinder 24. This shaft member 30
Is set such that its axial length is slightly longer than the dimension connecting the inner surfaces of the side plates 11, 11 and slightly protrudes from both end surfaces of the shelf plate 12, whereby both end portions 3 of the shaft member 30 are provided.
OA can enter into the recess 15 and engage with it. The shaft member 30 is exposed in the region of the operation allowance 26 in a state where the shaft member 30 is inserted into the holding cylinder 24, and the exposed portion is gripped to apply an external force such as pulling, thereby forcibly deforming partially. With this, both end portions 30A protruding from the outer end of the holding cylinder 24 can be retracted into the holding cylinder 24 and the engagement with the recess 15 can be released.

At two axial positions of the shaft member 30,
A flange member 31 is provided as a stopper that engages with the inner end of the holding cylinder 24. This flange member 31
Is detachably attached to the shaft member 30, and when the shaft member 30 is inserted into the holding cylinder 24, the operation allowance 2
It is mounted around the axis of the shaft member 30 in six areas. Further, the flange member 31 is provided so as to be immovable in the axial direction with respect to the shaft member 30 via means such as welding at a position where both ends 30A of the shaft member 30 equally project from the outer ends of the left and right holding cylinders 24. .

Next, the operation of this embodiment will be described with reference to FIG.

When the shelf plate 12 is hung between the side plates 11,
First, the portion of the shaft member 30 exposed in the region of the operation allowance 26 is gripped and a pulling force is applied. As a result, both ends 30A of the shaft member 30 retreat inward from the outer end of the holding cylinder 24 in accordance with the amount of flexural deformation of the region receiving the tensile force. Then, while keeping this state, the shelf plate 12 is pushed between the side plates 11 to bring the rear end surface of the shelf plate 12 into contact with the front surface of the back plate 13. In this state, when the pulling force on the shaft member 30 is released, the shaft member 30 tries to extend to the initial linear shape, but in the state where the outer end of the holding cylinder 24 does not coincide with the position of the recess 15. The respective end portions 30A of the shaft member 30 come into contact with the inner surface of the side plate 11 to be in a state in which the extension is restricted. Therefore, when the shelf plate 12 is vertically moved substantially horizontally toward the height position where the shelf plate 12 is to be installed, and when the outer end of the holding cylinder 24 is aligned with the recess 15, the initial axial line shape of the shaft member 30 is obtained. By the returning action of the shaft member 30
OA will enter the recess 15 and engage with it.

When carrying out the step change work of the shelf plate 12, the exposed portion of the shaft member 30 is pulled out without pulling out the shelf plate 12 from between the side plates 11, and the engagement state between the shaft member 30 and the recess 15 is released. Meanwhile, the shaft member 30 may be moved up or down to extend the shaft member 30 again at a desired height position.

Therefore, according to such an embodiment, there is an effect that it is possible to extremely easily and quickly carry out the work of hanging the shelf 12 between the side plates 11 and the work of changing the stage. Further, since the left and right width of the shelf board 12 is set to a dimension that causes almost no gap with respect to the inner dimension of the side board 11,
It is also possible to prevent the shaft member 30 from being inadvertently bent due to the weight of the shelf plate 12 and the weight of the article placed thereon.

In the above embodiment, the case where the shelf plate 12 is made of steel is shown and described.
The present invention can also be applied to wooden shelves. For example, as shown in FIG. 4, a single wooden shelf board 40 is provided, through holes 41 extending in the left-right direction are provided at two front and rear positions of the shelf board 40, and the shaft member 42 is inserted into the through hole 41. can do. At this time, a cross-shaped notch 43 for opening the through-hole 41 to the outside is provided in the central region along each through-hole 41, and the shaft member 42 can be partially exposed by using the notch 43 as an operating allowance. It is provided. Here, in FIG. 4, the first notch 43 in the direction along the through hole 41.
A is an area that allows bending deformation when pulling out the shaft member 42, and the second cutout portion 43B formed in a direction substantially orthogonal to the first cutout portion 43A holds the shaft member 42 with a finger. It is organized as an area. In this modification, in addition to the through hole 41, a groove may be provided to allow the shaft member 42 to be received, and a member for closing a part of the groove may be provided on the lower surface of the shelf board 40. is there. Also, the through hole 42
Alternatively, the shaft member 42 may be provided in a dovetail groove shape so as to hold the shaft member 42. Further, the through hole 42 is provided with a concave groove in two plate-like members, and these plate-like members may be combined with each other. It can also be formed by.

Also according to such a modified example, it is possible to efficiently carry out the 40 bridge work or the shelf change work of the shelves substantially in the same working procedure as the above embodiment.

The engaging portion in the present invention is the recess 15
The present invention is not limited to the above, but may be formed by a hole penetrating the inside and outside of the side plate 12. Further, two holding cylinders 24 are arranged in each row, but three or more holding cylinders 24 may be arranged on the same line as long as the operation allowance described above can be formed.
However, in order to facilitate the molding, the constitution of the above-described embodiment in which two pieces are set is advantageous. Further, the stopper is not limited to the flange member 31, and may be provided with a protrusion or the like that can be engaged with the inner end of the holding cylinder 24.
