JPH0998846A - Bendable tray - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily confirm and take out a document or the like stored inside by partly bending down the drawn part of a tray. SOLUTION: A tray 1 is formed out of a deep part 2 parallel to a desk 10 and a front part 3 bent to incline downward. The deep part 2 and the front part 3 are jointed to each other via hinges on the reverse side of the tray 1, and a bend restriction member 5 is laid for preventing the occurrence of the excessive bend of the tray 1. Furthermore, the tray 1 is provided with a means whenever necessary for allowing the front part 3 to be bent and normally keeping parallelism with the deep part 2, so as to function as a general-purpose tray. This means is formed, for example, out of a recessed member 17 and a projected member 18 coupled to each other extending over the side 20 of the deep part 2 and the side 21 of the front part 3, and then either of the recessed member 17 or the projected member 18 is pressed to the other through the action of an elastic force. Furthermore, the bend restriction member 5 is formed, for example, out of hardware 25 having one end rotatably engaged with one of the sides 20 and 21 of the deep part 2 and front part 3, and a limiting member coupled to the hardware 25 for limiting the slide motion thereof.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvements in desk drawers, document cases such as letter cases, and other similar relatively thin drawer trays.

[0002]

2. Description of the Related Art A so-called drawer type tray for the purpose of storing a desk drawer, letter case, other documents, etc. is generally a box shape with an open top and flat sides and bottom, depending on the purpose of use. The roller is arranged on the outer surface so that it can be smoothly taken in and out.
As a special mode, there is a structure in which when the tray is pulled out, the front part descends obliquely downward and the whole tray is held in an inclined state.

[0003]

As a way of using the tray, it is frequently used to drop one or two documents into the tray as they are, and the work of taking out the documents is also frequently done. It is difficult to take out a single-leaf document from a tray having a flat bottom surface, and the document is often damaged. Similarly, if a thick document is on the bottom of the tray, it is difficult to take out.

[0004]

According to the present invention, a drawer of a desk, a letter case, or other similar tray is constructed so that it can be bent downward at a predetermined position when the tray is pulled out. Solved the problem.

[0005]

Embodiments will be described in detail based on illustrated embodiments. In the figure, reference numeral 1 denotes a tray, which is composed of an inner portion 2 parallel to the desk 10 and a front portion 3 which is bent and inclined downward. The back portion 2 and the front portion 3 are connected to each other by a hinge 4 on the back surface of the tray 1, and a bending limiting member 5 is arranged so as not to cause excessive bending. The tray 1 is provided with means for allowing the front portion 3 to bend as necessary and normally forming a parallel with the back portion 2 to function as a general tray.

An example of such means is one in which curved spring steel 6 is fitted to holding members 13, 14, 15, 16 fixed to the back surfaces 11, 12 of the tray 1 as shown in FIG. Alternatively, as shown in FIG. 4, the side surface 20 and the front portion 3 of the inner portion 2
The concave member 17 and the convex member 18 which are engaged with each other over the side surface 21 of the concave member 17 and the convex member 18 may be configured to be pressed against the other member by the elastic force.

Further, as shown in FIG. 2, for example, the bending restricting member 5 is formed by connecting the cord members 24 to the piece members 22 and 23 fixed to the side surfaces 20 and 21 of the back portion 2 and the front portion 3 of the tray 1, respectively.
Through which the cord member 24 is penetrated and both ends of the cord member 24 are formed thick so as not to fall off from the piece members 22 and 23, or as shown in FIG. 6, one end is a side surface of the back portion 2 and the front portion 3 of the tray 1. Two
Metal fitting 25 rotatably locked to either 0 or 21
A structure other than that shown in the drawings is also applicable as long as it has a structure capable of achieving an equivalent function, such as a structure that is configured by a restriction member 26 that engages with the metal fitting 25 and restricts sliding of the metal fitting 25.

FIG. 5 shows another embodiment, in which the locking member 27 formed of synthetic resin or the like and the elastic pressure member 28 are provided on the side surfaces 20 and 21 of the back portion 2 and the front portion 3 of the tray 1, respectively. The engaging member 27 is provided with a concave portion 30 at a predetermined position, and a protrusion 32 is formed in the front portion of the concave portion 30, while the elastic pressure member 28 is provided with a convex portion 31 that engages with the concave portion 30. A protrusion 33 that abuts the protrusion 32 is formed in the front portion of the protrusion 31. When this is arranged as shown in the drawing, when the front portion 3 of the tray 1 is pulled out and pressed downward, the concave portion 30 and the convex portion 31 which have been engaged until then are disengaged, and the elastic pressure member 28 is locked by the locking member 27. The slide of the elastic member 28 is restricted by the abutment of the protrusion 32 and the protrusion 33, and the slide of the elastic member 28 does not slide any more, and the front portion 3 of the tray 1 is bent at a predetermined angle. After use, when the front portion 3 of the tray 1 is pulled up, the elastic member 28 slides and the concave portion 30 and the convex portion 31 engage with each other to lock the front portion 3. With this configuration, the tray 1 described above
It is not necessary to dispose the spring steel 6 on the back surfaces 11 and 12 of the above.

In addition to the above, if the tray 1 is provided with a mechanism for allowing the refraction and a mechanism for restricting the refraction, the same function as described above can be exhibited, and various modifications are possible. Needless to say.

[0010]

As described above in detail, according to the present invention, a tray or a drawer or a part having a similar function is bent downward to bend a portion of a document or the like stored therein. It is very effective because it can be easily confirmed and taken out.
