Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray for storing documents, and more particularly, to a tray in which a document placed in an upright position falls on the bottom of the tray. This is a tray suitable for use when performing work by a sorting machine at a post office, for example. In this specification, the term “tray” is used as a concept that includes not only a dish-shaped container but also all other containers that can store and store documents, such as a drawer such as a desk or a cabinet. . 2. Description of the Related Art At present, a postal code system is adopted for postal matter, and the postal code written on the postal matter is read and sorted by a sorting machine. From 1998, a seven-digit postal code has been adopted, and the delivery bureau is scheduled to pass through the sorting machine twice to arrange the mail in the order along the delivery route actually followed by the delivery staff. In this case, it is necessary to keep the mail that has been subjected to the first sorting operation without breaking the sorted condition for the second sorting operation, and temporarily store it in a tray for each sorting operation. It will be. At that time, in order to use the space efficiently, it is convenient to arrange a large number of trays on the shelf vertically and horizontally, but in that case, the upper part of a certain tray is placed on another shelf. It will be blocked by the tray and you will not be able to enter mail from the top of the tray. Accordingly, the tray is opened forward, inserted from the front of the tray, and placed sequentially from the rear of the tray. At that time, if the postal matter falls in the tray, it is difficult to put in the next portion, and it is also difficult to take it out when taking out. [0003] A container for storing documents, such as a drawer of a desk, a cabinet, etc., stores a document or a file in which the document is closed.
There is a type in which the container is stored in an upright state, instead of being stacked on the bottom of the container. In this case, if the amount of documents stored in the container space is small, the documents fall down without standing in the container. In order to prevent this, for example, a slit is formed in the side wall of the drawer, and a partition plate having an ear fitting into the slit is attached to prevent a document or file from falling over by the partition plate. are doing. [0005] However, in this configuration, it takes a lot of cost to process the parts, and sometimes it is necessary to change the mounting position of the partition plate. Furthermore, this type of arrangement cannot be employed in the above-described front-sided mail storage tray. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and can prevent a document or a file stored therein from falling down.
An object is to provide a tray for storing documents that can be manufactured at low cost. [0007] In order to solve the above-mentioned problems, in the document storage tray according to the present invention, a plurality of convex strips extending in the front-rear direction of the tray are provided on the inner surface side of the bottom plate. G
It was formed at intervals in the left and right direction of the leh. At the top of each of the convex strips, a tray
Multiple notches at the same position,
The key is engraved. [0009] The cross section of the notch has a substantially “レ” shape.
And the inner side of the vertical part of the “レ” is behind the tray.
It faces the wall. Hereinafter, specific embodiments of the present invention will be described with reference to the drawings, but the scope of the present invention is not limited to the embodiments described below. FIG. 1 shows a state in which a plurality of trays 10 according to a first embodiment of the present invention are arranged on a shelf for use in performing postal sorting work. FIG. 2 is a side view of FIG. Reference numeral 1 denotes a shelf, which is composed of five upper and lower shelves 2A, 2B, 2C, 2D, and 2
E, each shelf is partitioned into a plurality of tray storage sections 2A1, 2A2, 2A3, etc. by partitions 3A, 3B, 3C, etc., and a tray 10 is stored in each of them. FIG. 3 is a plan view of the tray 10, and FIG.
FIG. 4 is a sectional view taken along line 4-4 in FIG. The tray 10 has a bottom plate 12. The shape of the bottom plate 12 is a rectangle slightly longer in the front-rear direction of the tray 10. A front wall 14 and a rear wall 16 are erected from a front edge and a rear edge of the bottom plate 12.
Further, a right side wall 18 and a left side wall 20 are erected from the right edge and the left edge of the bottom plate 12. The right and left side walls 18, 20 and the rear wall 16 are at the same height, but the height of the front wall 14 is lower than those, and the front side of the tray 10 is open. Therefore, even if the trays 10 are arranged vertically on the shelf 1 as shown in FIGS. 1 and 2, mail can be inserted from the front side of the trays 10. Both the front and rear walls and the left and right side walls are provided with a small taper, and are slightly inclined outward as going upward. Therefore, the other trays can be nested and stored on one tray, and the storage space of the tray when not in use can be reduced. In addition, a shallow dent 24 having a predetermined length 1 is formed at the same position in the upper and lower edges 22 of the right and left side walls 18 and 20 in the front-rear direction of the tray. 20 is slightly larger than the width b between the outer surfaces at the bottom. Further, the lower edges of the right and left legs 30, 32 formed in the front leg 26, the rear leg 28, the right leg 30, and the left leg 32 which are formed at a short height on the lower surface side of the bottom plate 12 and are continuous with each other. 34, a shallow depression 36 having a predetermined length L is formed at the same position in the front-rear direction of the tray, and the length L of the depression is determined by the width B between the outer surfaces of the upper end portions of the right and left side walls 18 and 20 of the tray 10. It is slightly larger. Therefore, one tray can be stably stacked on another tray with the other tray oriented in a direction perpendicular to the tray.
Even if mail pieces are stacked in the tray 10, the mail pieces inside will not be damaged. On the inner surface side of the bottom plate 12 of the tray 10, a plurality of convex protrusions, that is, convex stripes 38 extending in the front-rear direction of the tray 10 at predetermined intervals in the left-right direction of the tray 10 are formed. As shown in FIG. 5, the ridge 38 has a circular cross section. However, the shape is not necessarily limited to this shape. For example, the cross-sectional shape may be rectangular. Notches 40 are formed in the plurality of ridges 38 at predetermined intervals in the front-rear direction of the tray 10 and at the same position in the front-rear direction of the tray 10. That is, the notches 40 formed in the respective ridges 38 are formed on the same straight line extending in the left-right direction of the tray 10. FIG. 6 is an enlarged sectional view of a portion H in FIG. As is clear from the drawing, the cross section of the notch 40 has a substantially “レ” shape, and the inner surface 42 of the straight portion thereof is the tray 10.
Facing the rear wall 16. The inner surface 42 of the straight portion
Has a slight taper so that its upper edge approaches the front wall 14. When mail items are sequentially put into the tray 10 configured as described above from the back, the last mail item T1 becomes
The upper end of the postal matter Tm is tilted in a state of being in contact with the inner surface of the rear wall 16, and if that is the case, it slips on the bottom plate 12 and falls down. It fits into the cutout 40 made in the shape of a circle and prevents slipping, so that it does not fall down. Further, some forward mails Tn fit into the notches 40 in a line in front of them. Normally, mail items are put together in the tray 10 at a time, approximately 80 mails at a time.
Inside, thereby preventing it from falling over. In addition, when taking out, contrary to the case of putting in, it takes out sequentially from the near side of the tray 10. At this time, at the center in the left-right direction of the rear wall 16, at least a recessed portion 43 from which the finger can be inserted is formed from the upper edge to a predetermined position below, so that the postal matter placed in the rearmost portion is formed. Can be easily taken out. In the present embodiment, the cutouts 40 are not continuous in the left-right direction of the tray 10, but the plurality of cutouts 40 arranged in the left-right direction constitute a single groove. In this embodiment, the tray 10 is made of a transparent plastic material, so that the remaining mail can be checked from the outside, which is convenient. Although not shown in the drawings, in another embodiment, the convex ridges 38 provided in the first embodiment are not provided, and the cross section of the letter "L" is directly formed on the flat inner surface of the bottom plate 12. Alternatively, a “V” -shaped groove extending in the left-right direction of the tray 10 may be formed. Naturally, in this case, the groove is formed in a continuous shape, unlike the notch 40 in the first embodiment. In still another embodiment, instead of the notch 40 or the groove in the first embodiment,
It is also possible to employ a convex strip formed on the inner surface of the bottom plate 12 and extending in the left-right direction of the tray 10 at a predetermined interval in the front-rear direction of the tray 10. In that case, the ridge may have a continuous shape, but may be formed in a discontinuous state like the notch 40 in the first embodiment. As is apparent from the above description, the shape of the notch 40 or the groove, and further, the shape of the convex strip are not limited to those described above. Any shape can be used as long as it can contact the lower edge of the mail and prevent the mail from slipping beyond that position. The tray used for storing and storing mail has been described above as an example, but the present invention is applicable to other documents such as a drawer of a desk or a cabinet, and further to general containers for storing and storing files in which documents are closed. Clearly, it is possible. As described above, according to the present invention,
A locking portion is formed on the bottom plate of the tray to abut the lower edge of a document or file placed in an upright position and to prevent the lower edge from moving beyond that position, so that the document can be prevented from falling down . In addition, unlike the conventional configuration using a partition plate or the like, by opening the front side, documents can be taken in and out not only from above the tray but also from the front side to the innermost part of the tray. Therefore, it is very convenient when the sorting work is performed by arranging the trays in an overlapping manner, such as a mail sorting operation. In addition, it can be molded integrally with plastic and can be manufactured at low cost.
