DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawer for a multi-drawer storage case.

[0002]

2. Description of the Related Art Conventionally, this type of product is disclosed in Japanese Utility Model Application Laid-Open No.
No. 87539 and Japanese Utility Model Publication No. 7-19301 are known, but the following function is imposed on the surface of the roll (8) in Japanese Utility Model Publication No. 7-19301 [A], due to friction with the upper drawer bottom plate (24). The rotation of the roll (8) must be ensured, and the floating document must be handled below the arm A (1) and the arm B (2) [B]. Stop the reverse rotation of the roll (8). When pulling out the drawer, an opposing action is required that the frictional resistance with the upper drawer bottom plate (24) must be minimized. However, the function of [A] is sufficiently fulfilled by the mechanism of Japanese Utility Model 7-19301. For this purpose, the spring action of the arms A (1) and B (2) should be increased. However, when the action [B] is performed, the frictional resistance becomes too large and the upper drawer (24) is lifted up. Pull it out The Migihitsuji result, contrary to the arm A (1), if less frictional resistance to weak spring action of B (2) is responsible for [A] results not fulfill the well.

[0003]

In such a conventional structure, it is very difficult to fix the roll (8) to the upper drawer (24), and the rotation of the roll (8) reduces the frictional resistance of the claw (3). There is not enough available and the handling of documents is also insufficient. The present invention has been made in view of the above circumstances, and the structure of the roll (8) and the transformation of the arms A (1) and B (2) solve this conflicting effect and prevent the document from falling backward. It is a thing that was made.

[0004]

Means for Solving the Problems In order to solve the above-mentioned problems, the following description will be made with reference to FIGS. 1 to 5 corresponding to the present invention. 1. Integrated molding with arm bodies A (4) and B (5). The slide bearings A (12) and B (13) with long holes are attached to the plates C (8) and D (9)
The arm A is not parallel to the upper end line “BB line” of (5).

A rubber plate (32) having a protruding (37) is formed, and the distance between the catchers A (33) to E (37) is high only in the rotation direction of the roll A (25). In order to form the contact point with the upper drawer as a point with a diameter of 0.5 mm or less, and to reduce the frictional resistance when the rotation of the roll A (25) is stopped, a rubber plate (3
2) In order to complete a complete design at a ratio of 1.0 to 2.2 or more in the vertical and horizontal composition ratio of 2), it is formed independently and has a low density in the horizontal direction. 1. The fixing position of the roll A (25) with respect to the drawer is performed by sandwiching the rear side plate of the drawer between the body (18) and the presser (20) to form the adjuster A (21), B (22). ), The height can be adjusted by the combination of the C (23) and the stopper (24). We take technical means to say.

[0005]

When the present invention is mounted on the rear side plate of the drawer, the roll A (25) and the shaft A (2) are brought into close contact with the upper drawer by the spring action of the arms A (1) and B (2).
6) and B (27) are moved to the left ends of the slide bearings A (12) and B (13) by the contact friction by the action of inserting the drawer, and the roll A '(25') and the shaft B '(2) are moved.

A state of high adhesion due to the spring action of (2) is formed, and a rubber point with flexibility is formed, and the points are defined as A (33) and B only in the rotation direction of the roll A (25). (34),
The roll A '(25') is smoothly rotated by continuing the high density in the order of C (35), D (36) and E (37). Conversely, in the operation of pulling out the drawer, the roll A (25) and the shafts A (26) and B (27) rely on the contact friction between the upper drawer and the catchers A (33) to B (37) for the slide bearings A (12), B (13) is moved to the right end (see FIG. 2) and slide bearing A
(12), arms A (1) and B by the mechanism of (13)
By the return of the spring action of (2), the state of low adhesion is brought about, and a reverse rotation (right rotation) is attempted.
Since the shafts A (26) and B (27) fixed to 5) have pins A (30) and B (31) on both sides, the pins A (30) and B (31) are stoppers. A (1
4) When the drawer is pulled out while the rotation of the roll A (25) is stopped, the catcher A (33) in contact with the upper drawer stops when the roll A (25) stops rotating.
The contacts A to E (37) have one or two complete designs due to the stop of the rotation of the roll A (25), and the laterally low-density catchers A (33) to E (37). 37)
With this structure, the frictional resistance can be very small. Thus, the slide bearings A (12) and B (13)
Interaction of the mechanism of the above with the structure of the roll A (25),
When the rotation of the roll A '(25') is necessary, the arm A
(1) It is contradictory to realize reliable rotation even when the spring action of B (2) is weak, and to minimize the frictional resistance when pulling out the drawer while stopping reverse rotation of roll A (25). The action is solved, and the catcher A (33) ~
The uneven shape of the surface of the roll A (25) having the E (37) is such that the leading end of the document floating in the drawer easily enters the recess and that the roll A '(25') rotates reliably. Accordingly, the document is handled and guided below the arms A (1) and B (2), thereby preventing the document from falling backward.

And the shaft A (26) and the shaft B (27) each having the pins A (30) and B (31) on one side and the shaft keys A (28) and B (29) on the other. With the key A (28) and the shaft key B (29) inside, they are inserted from the holes A (10) and B (11) and fixed to the roll A (25) (see FIG. 4).
(10) and B (11) have covers A (16) and B (1
7) Attach. FIG. 2 shows the plate B (7) in FIG.
FIG. 4 is a partial cross-sectional view of the crushing, in which the positions of the roll A (25) and the shaft B (27) in the solid line are the roll A;
The state where the reverse rotation of (25) is stopped is shown, and the roll A '(25') and the shaft B '(27') indicated by the dotted lines show the rotation state of the roll A (25) necessary for inserting the drawer. Show. The slide bearing B (13) having a long hole for the shaft B '(27') to move while rotating is provided with a roll A '(25') and a roll A (25) with respect to the upper drawer.
In order to change the degree of adhesion, the upper end line "BB line" of the arm body B (5) is not made parallel to the arm B (2), and the gap on the side of the arm B (2) is made large. )
During rotation, the roll A '(25') is formed so as to be sufficiently exposed from the left ends of the plates C (7) and D (9) and the upper end of the arm body B (5), and the reverse of the roll A (25). Stopper B held on plates B (7) and D (9) right next to slide bearing B (13) to stop rotation
By forming (15) and providing a pin B (31) at the end of the shaft B (27) fixed to the roll A (25), the rotational position of the shaft B (27) can be changed to the slide bearing B (13). Pin B (31) when moved to the right end of
And the stopper B (15) are brought into contact with each other, so that the rotation of the roll A (25) is stopped. Although not shown, the auxiliary mechanism of the arm body A (4) and the mechanism of the shaft A (26) have the same structure. (See FIG. 4). The degree of adhesion at the point of contact between the upper drawer and the catchers A (33) to E (37) depends on the structure of the slide bearings A (12) and B (13), and the right end of the long hole is The space between the upper drawer and the left end is wider than that of the upper drawer, and the roll A (2
When the rotation of 5) is required, the arm A is moved to the left end by the contact friction (the state of the roll A ').
(1) The degree of adhesion can be increased by the action of the spring of B (2). Conversely, when it is desired to stop the rotation of the roll A (25), the degree of adhesion can be reduced by moving it to the right end by contact friction. FIG. 3 is a cross-sectional view taken along the line AA in FIG. 1 and shows a mechanism for adjusting the height of the rear side plate of the drawer and the roll A (25), and the fixing position of the roll A (25) is an adjuster. Up and down adjustments can be made centering around the case where the stopper (24) is inserted and fixed in the B (22), so that it can be used for various types of storages with different distances from the upper drawer. To do. The structure is a stopper (2
4) Adjusters A (21) to C which are formed to have a length longer than the thickness of the body (18) and are provided on both sides of the body (18)
Insert the holder (1) in front of any of (23).
9) The body (18) and the presser ((20)) are partly protruded to the protruding stopper (24).
The height of the roll A (25) is determined by applying the upper end of the rear side plate sandwiched between the upper drawer and the roll A (2).
5) Adjust the degree of close contact with. FIG. 4 is a fragmentary sectional view of the roll A (25), shafts A (26), B (27) and slide bearings A (12), B (13) in FIG. Shows a simple structure. FIG. 5 is an enlarged plan view of the rubber plate (32) in the roll A (25), showing the vertical and horizontal densities and configurations of the catchers A (33) to E (37), and showing the relationship with FIG. A (33) to the catcher A '(33') in the vertical (rotational direction of the roll A) interval and the catcher A (3
3) The horizontal (roll A width direction) interval from the catcher A ″ (33 ″) to the catcher A ″ (33 ″) is set to a ratio of 1.0 to 2.2 or more, and the catchers A (33), B (34), C
(35), D (36), E (37) The tip spacing in the rotation direction of each is set to 0.5 mm or less in the actual product, so that the independent cone-shaped catchers A (33) to E (33) to E
(37) and high-density catchers A (33) to E (37) in the rotation direction of the roll A (25) are formed,
A low-density configuration was formed in the lateral direction. Therefore, the catchers A (33) to E (37) are formed as rubber points (cone vertices) having flexibility, and the catchers A (33) to E (37) are formed by the roll A (25). It is possible to ensure smooth and reliable rotation of the roll A (25), which is necessary when a drawer is inserted, by forming the point close to a line by continuously connecting the rollers at a high density only with respect to the rotation. Regarding the frictional resistance when the rotation of A (25) is stopped, the upper drawer may be used depending on the structure in which the rotation of the roll A (25) is stopped and the low density catchers A (33) to E (37) are arranged in the lateral direction. The contact (1) has one or two points (vertices of a cone) in one complete design, and the total contact area of the roll A (25) is extremely small, so that the frictional resistance can be reduced.
In addition, since the catchers A (33) to E (37) are formed as independent independent projections on the rubber plate (32), a large number of irregularities are formed on the surface of the roll A (25). By rotating the unevenness together with the roll A '(25'), the leading end of the document floating in the drawer can be reliably guided to the lower side of the handling arms A (1) and B (2).

[0007]

According to the present invention, the drawer can be easily attached to the drawer because of the above structure, the rotation of the roll A '(25') can be reliably obtained when the drawer is inserted, and the drawer can be pulled out. Since the frictional resistance with the upper drawer is extremely small, the method of use is arbitrary, and the feeling of use is not changed at all. It is complete and can prevent falling backwards.
