Description

[Detailed description of the invention] Industrial field of application The present application relates to a storage device for storing, for example, floppy disks, which is configured in multiple units by assembling unit storage bodies in which drawers can be pulled out and horizontally increased and decreased. Regarding furniture.

Prior Art and Problems Conventionally, a unit storage unit in which a drawer can be pulled out using a guide rail is assembled so that it can be increased or decreased in the horizontal direction, and is used to construct a multiple unit storage unit with a relatively long depth, such as a floppy disk. Storage furniture for storage is well known.

However, in this configuration, if, for example, one drawer is pulled out and another drawer is pulled out, the center of gravity of the entire storage furniture moves forward, and there is a risk that it may fall over.

Purpose, Examples, and Effects of the Invention Therefore, the present application locks the drawer of the other unit storage unit so that it cannot be pulled out when the drawer of one adjacent unit storage unit is in the drawn state. The defect has been improved, and the example will be described in detail with reference to the drawings below.
This is a known unit storage body in which a drawer 3 is housed in a drawer 3 that can be freely drawn out via a suspension rail 2, and a flat horizontal hole 4 is opened at the lower front position of the side wall of the casing 1. The suspension rail 2 and the drawer 3 also include a horizontal hole 5 that matches the horizontal hole 4 when the drawer 3 is housed in the housing 1, and an engagement hole having a V-shaped planar shape. 6 are provided respectively. 7 is a vertical reinforcing rib provided on the inner surface of the side wall of the housing 1; 8 is a roller that guides the sliding movement of the suspension rail 2;
is slidably supported on the suspension rail 2. Reference numeral 9 designates a protrusion protruding from the front lower part of the side surface of the drawer 3 to face the lower surface of the suspension rail 2 in order to form the engagement hole 6, and 10 represents a mirror plate of the drawer 3.

B is a lock portion that freely moves laterally within each of the horizontal holes 4 and 5 and the engagement hole 6 across the adjacent units when the unit storage body A configured as described above is assembled in the horizontal direction. Thin cam portions 12 are provided at both ends of a thick central portion 11 that moves within the horizontal holes 4 and 5 between adjacent ones, and which relatively engage with the engaging holes 6 between the adjacent ones.
12 is extended, and its entire length is such that when one cam part 12 is fully engaged with the engagement hole 6 of one unit storage body A, the other cam part 12 is connected to the other unit storage body A. The unit storage body is configured such that it escapes from the engagement hole 6 of the body A and the horizontal hole 5 of the suspension rail 2, and its tip comes into contact with the outer surface of the rail 2, and if the unit storage body does not have the suspension rail 2. When the target is the drawer 3, the tip of the other cam portion 8 is set to come into contact with the outer surface of the drawer 3.

That is, FIGS. 2 and 3 show the engagement hole 6 in the unit storage body in the left position and the horizontal hole 5 in the suspension rail 2.
The figure shows a state in which the left end cam portion 12 of the lock piece B has escaped from the lock piece B, and the right end cam portion 12 is engaged with the engagement hole 6 in the unit storage body at the right position. Position unit storage drawer 3
The drawer 3 of the unit storage body in the right position is restrained by the lock piece B.

In other words, when the drawer 3 in the left position is pulled out, the horizontal hole 5 in the left position and the engagement hole 6 are out of alignment with the horizontal hole 4 provided in the housing 1, so that the drawer 3 in the right position is pulled out. When an attempt is made to pull it out, the lock piece B is
A leftward lateral force is applied to the lock piece B.
The left end of the drawer 3 abuts against the outer surface of the suspension rail 2 at the left position or the outer surface of the drawer 3, preventing its leftward movement, and therefore the drawer of the drawer 3 at the right position is locked by the lock piece B.

From this state, when drawing out the drawer 3 at the right position, the drawer 3 at the left position is fully accommodated within the housing 1. Then, as shown in FIGS. 2 and 3 again, the horizontal holes and the engagement holes are aligned horizontally, and from this state the drawer 3 in the right position is pulled out. Then, lock piece B
Due to the action of the oblique edge of the cam portion 12 and the oblique edge of the engagement hole 6, a leftward lateral force is applied to the lock piece B, and the right end cam portion 12 escapes from the engagement hole 6, and then Suspension rail 2 is removed when drawer 3 is pulled out.
When the cam portion 12 moves toward the front, the cam portion 12
further escapes through the horizontal hole 5. On the other hand, as the lock piece B moves to the left, its left end cam portion 12 engages with the engagement hole 6 of the drawer 3 in the left position, and as a result, the drawer 3 in the left position cannot be pulled out.

Effects of the invention Since the present application is constructed as described above, there is no risk that storage furniture will fall down due to multiple drawers being pulled out at the same time in adjacent unit storage units, and it can be used safely. According to the above, when assembling a lock piece into a unit storage body, it is sufficient to insert the lock piece from the side into a horizontal hole opened on the side of the housing, so it is easy to assemble and use the lock piece. It has advantages such as being extremely convenient when increasing or decreasing the number of unit storage bodies depending on the aspect, and having an extremely simple structure.

[Brief explanation of the drawing]

The drawings show an embodiment of the present application, and FIG. 1 is a side view of the unit storage body with the drawer pulled out, FIG. 4 is a plan view of the lock piece. In the figure, A is a unit storage body, 1 is a housing, 2 is a suspension rail, 3 is a drawer, 4 and 5 are horizontal holes, 6 is an engagement hole, B is a lock piece, 11 is a thick center part, 12
is the cam part.
