  EMBODIMENT OF THE INVENTION The form for implementing the tray which concerns on this invention, and its storage shelf is demonstrated below based on an Example.

  FIG. 1 is a plan view of a tray 1 according to the present invention used by students to store gym clothes, for example, in a school, etc. FIG. 2 is an enlarged longitudinal sectional view taken along line II-II in FIG. FIG. 4 is an enlarged longitudinal sectional view taken along line III-III, and FIG. 4 is a perspective view. For convenience, in the following description, the front-rear direction refers to FIG. That is, the upper part of FIG. 1 is described as the front, the lower part as the rear, the left as the left, and the right as the right.

  The tray 1 has a substantially square box shape in plan view including a bottom plate 2 and front and rear and left and right side plates 3 and 4, and an article storage space having an open top surface is formed inside. In addition, a large number of long holes 5 are formed in the bottom plate 2 in order to improve air permeability.

  An outward flange 6 having a substantially inverted L-shaped cross section that is continuous with each other is integrally connected to the upper edges of the front and rear side plates 3 and 4. An inward protruding portion 7 is formed at the center of the front and rear side plates 3 and 3, and an indented recess 8 is formed on the outer surface facing the protruding portion 7 (see FIG. 4). ). When stacking the trays 1, the recesses 8 of the upper tray 1 are fitted into the protrusions 7 of the lower tray 1 from above. In order to facilitate this fitting, the widths of the protruding portion 7 and the recessed portion 8 are gradually reduced upward.

  In the left and right side plates 4 and 4, grip holes 9 and 9 are formed in the central upper portion immediately below the outward flange 6. The front, rear, left and right side plates 3, 4 are slightly inclined so as to gradually expand upward so that the upper and lower trays can be nested.

  The front and rear left and right side plates 3 and 4 are attached to the center portion in the vertical direction of the inner surface including the protrusion 7 in the front and rear side plates 3 and 3 and the inner surface of the center portion in the vertical direction in the left and right side plates 4 and 4. The inner surface of the front, rear, left and right side plates 3 and 4 is bent inward so that the width dimension of the lower half is slightly smaller than that of the upper half. The stop portion 10 is formed to be continuous at the same height.

  As shown in FIG. 5, when the upper and lower trays 1 are stacked in the same direction, the lower half of the upper tray 1 is fitted to the upper half of the lower tray 1 so that The lower ends of the left and right side plates 3 and 4 are locked to the first locking steps 10 of the front and rear side plates 3 and 4 of the lower tray 1. At this time, in order to prevent the upper and lower trays 1 from coming into close contact with each other and facilitate insertion and removal, the width dimension between the inner surfaces of the upper half portions of the front and rear side plates 3 and 4 is set to the front and rear left and right sides. The width dimension between the outer surfaces of the lower half portions of the face plates 3 and 4 is slightly larger.

  As shown in FIGS. 3 and 4, the inner surfaces of the upper end portions of the left and right side plates 4, 4 are bent outwardly at portions other than both ends in the longitudinal direction so that the outer side which is long in the front-rear direction is removed. Oriented second locking step portions 11 and 11 are formed. As shown in FIGS. 2 and 3, the dimension L1 between the outer surfaces of the lower half portions of the left and right side plates 3 and 3 excluding the recesses 8 is the second locking step portion of the front and rear side plates 4 and 4. 11 is slightly smaller than the dimension L2 between the opposing surfaces above 11.

  Next, the usage method of the tray 1 of the above-mentioned Example is demonstrated. As shown in FIGS. 4 to 6, when the tray 1 is not used, the upper and lower trays 1 are set in the same direction, that is, in this example, the protruding portions 7 of the upper and lower trays 1 and the handle holes are in the same direction. Are stacked in the upper half of the front and rear side plates 3 and 4 in the lower tray 1 so that the lower half of the front and rear side plates 3 and 4 in the upper tray 1 are nested. The lower ends of the side plates 3 and 4 of the upper tray 1 are brought into contact with and locked with the inwardly facing first locking step 10 of the tray 1. Thus, by stacking the lower half portions of the plurality of trays 1 in a nested manner, the stacking dimensions of the trays 1 are reduced, and the plurality of trays 1 can be efficiently stored.

  On the other hand, when the tray 1 is used, that is, when an article is accommodated in the tray 1, a plurality of upper and lower trays 1 are alternately stacked at 90 degrees different directions as shown in FIG. Then, the lower ends of the side plates 3 before and after the upper tray 1 are fitted to the upper ends of the left and right side plates 4 of the lower tray 1, and the lower ends of the upper tray 1 and the lower tray 1 2 is locked to the locking step 11. As a result, a large space is formed between the opposing surfaces of the bottom plate 2 in the upper and lower trays 1, and articles stored in the lower tray 1 are prevented from being pressed by the bottom plate 2 of the upper tray 1. Since the upper and lower trays 1 are positioned and stacked, there is no possibility of being displaced due to displacement.

  As described above, in the tray 1 of the above-described embodiment, when the tray 1 is not used, a plurality of trays 1 can be nested and stacked in the same direction, so that the stacking dimensions can be reduced and efficiently stored. In addition, when the tray 1 is used, a plurality of upper and lower trays 1 are alternately stacked at 90 degrees, so that the lower tray 1 can be placed between the opposing surfaces of the bottom plate 2 in the upper and lower trays 1. Since a space that does not press the accommodated articles is formed, and the upper and lower trays 1 are not displaced, the user-friendly tray 1 can be provided.

  Further, an inward first locking step portion 10 is provided on the inner surface of the center portion in the vertical direction of the front, rear, left and right side plates 3, 4, and an upper tray directed in the same direction is provided on the first locking step portion 10. Since the lower ends of the front, rear, left and right side plates 3, 4 are in contact with each other, it is possible to prevent the upper and lower trays 1 from being deeply fitted to each other and stacked, so that the upper and lower trays 1 can be easily separated. .

  FIG. 8 is a front view of a storage shelf used in a school or the like for storing the tray of the above-described embodiment. The storage shelf 12 has a vertically long box shape with an open front, and a storage space S for the tray 1 is formed between the left and right side plates 13 and 13 and the intermediate side plate 14 at the center.
