DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an overall view of the workstation 10.

The workstation 10 is housed in a box 12. The box 12 has a drawer 30 for storing the keyboard 14. The state drawn by a solid line indicates a state where the drawer 30 is opened, and the state drawn by a two-dot chain line indicates a state where the drawer 30 is closed.

In the box 12, a computer main body 16 is provided.
And the display 18 are stored. The printer 20 is mounted on the upper part of the box 12 as indicated by a two-dot chain line.

FIG. 2 shows a drawer 3 provided with a lock device 50.
0 is shown in a perspective view. The drawer 30 is the front wall 3
2, the side walls 34, 34, the rear wall 36, and the bottom plate 38 are formed in a box shape. Side walls 34, 3 of drawer 30
Rails 34a, 34a (only one is shown) are attached to the outer surface of each of the four along the longitudinal direction of the side wall 34. Each side wall 34 has a through hole 34b through which a lock piece 56 of the lock device 50 protrudes and retracts, as described later. Reference numeral 40 denotes a drawer storage frame for storing the drawer 30. The drawer storage frame 40 has a channel shape. Both sides frame 4 of drawer storage frame 40
Guide rails 44, 44 for guiding the rails 34a, 34a are provided inside the rails 2, 42. In each side frame 42, a plurality of through holes 46, 46 are formed in a row along the longitudinal direction of the side frame 42 so as to correspond to the through holes 34b.

The lock device 50 is provided along the bottom plate 38 of the drawer 30. This locking device 50
An operation lever 52 extending in the longitudinal direction of the drawer 30, a pair of left and right L-shaped links 54, 54, and the L-shaped links 54, 5
4 and left and right lock pieces 56, 56.

The operating lever 52 has a handle 5 at its tip.
2a. The bottom plate 38 near the handle 52a
Although not shown, it is hollowed out so that the operation lever 52 can be operated.

Each end of one leg 54a of each L-shaped link 54 is connected with a rear end of the operating lever 52 by a connecting pin 54c. Each distal end of the other leg 54b is connected to each base end of the lock pieces 56,56. Each of the L-shaped links 54 is provided with support pins 55, 55.
Is supported so as to be rotatable around the center.

Each lock piece 56 is fixed to the fixed guide plate 5 so as to pass through a guide hole 60 formed in the fixed guide plate 58.
8 supported. The fixed guide plate 58 is connected to the drawer 30.
Is fixed to the bottom plate 38. Each lock piece 56 has a head portion 56a, and has a mushroom shape as a whole (see FIG. 3). Compression coil springs 62, 62 are interposed between the head 56a of each lock piece 56 and the fixed guide plate 58. Therefore, the lock piece 56
Are always urged to project outward with respect to the fixed guide plate 58.

FIGS. 3 and 4 are enlarged plan views of the lock device 50, showing the operation of the lock device 50. FIG.

In FIG. 3, the lock piece 56 is urged by a resilient force of the compression coil spring 62 so as to protrude beyond the side wall 34 of the drawer. The resilient force of the compression coil spring 62 causes the head 5 of the lock piece 56 to move.
The lock pieces 56a enter the receiving holes 46 formed in the side frames 42 of the drawer storage frame 40 (see FIG. 2).
And the side frame 42 are engaged. Therefore, drawer 30
(See FIG. 2) is locked with respect to the drawer storage frame 40.

Referring to FIG. 4, the handle 52 shown in FIG.
When "a" is pulled forward, the operation lever 52 is pulled in the direction of the arrow. Then, the left and right L-shaped rings 54, 54 rotate around the respective support pins 55, 55. By the rotation of the L-shaped links 54, 54, the distal ends of the other legs 54b, 54b are respectively compressed by the compression coil spring 6
They rotate inward, respectively, against the resilience of 2,62.
By the inward rotation of the other legs 54b, 54b, the lock pieces 56, 56 connected thereto move inward of the drawer 30 (see FIG. 2), respectively, and the heads of the lock pieces 56, 56 are moved. The distal ends of the portions 56a, 56a come out of the receiving holes 46 formed in the side frames 42, 42 of the drawer storage frame 40 (see FIG. 2), and engage with the lock pieces 56, 56 and the side frames 42, 42. The lock is released and the locked state is released. In this state, the drawer 30 is
0, the drawer 30 can be moved back and forth. That is, the handle 5 shown in FIG.
The lock state of the drawer 30 is easily released by the one-touch operation of pulling the 2a forward.

When the drawer 30 is moved back and forth in the state where the lock of the drawer 30 is released, and the hand is released from the handle 52a at an arbitrary position, the lock pieces 56, 56 are resilient by the compression coil springs 62, 62. It moves outward by the action of the force, and as shown in FIG. 3, the tip portions of the heads 56a, 56a fit into the receiving holes 46, 46 of the side frames 42, 42, and the drawer 30 is locked.

FIG. 5 shows another example of the locking device, in which a detent (hereinafter referred to as “ball tightening”) 70 using a metal ball is attached to the side wall 34 of the drawer 30. The structure of the ball clamp 70 is shown in detail in FIG.

Referring to FIG. 6, ball tightening 70 includes a cylinder 72, a steel ball 74 housed in cylinder 72, and a compression ball interposed between ball 74 and the bottom of cylinder 72. It consists of a spring 76. The ball 74 is always urged in the opening direction of the cylinder 72 by the elastic force of the compression spring 76. The ball tightening 70 is mounted on the side wall 34 via the mounting plate 77 so that the ball 74 faces outward of the side wall 34. As shown in FIG. 5, the side frame 42 of the drawer storage frame 40 has a plurality of receiving holes 78 that engage with the balls 74 of the ball tightening 70 along the longitudinal direction of the side frame 42.

FIG. 6A shows a state in which the ball 74 of the ball clamp 70 is engaged with the receiving hole 78 formed in the side frame 42 of the drawer storage frame 40. Therefore, the drawer 30 is locked in the drawer storage frame 40.

When the drawer 30 is pulled in the arrow direction shown in FIG. 6B from the locked state of the drawer 30,
The ball 74 of the ball tightening 70 is pressed by the side frame 42 and retracts inward of the cylinder 72 against the elastic force of the compression spring 76. When the drawer 30 is further pulled, the ball 74 is moved to the receiving hole 7 adjacent to the receiving hole 78 with which the ball has been engaged.
8 and engages with the adjacent receiving hole 78 by the elastic force of the compression spring 76. Drawer 30
The drawer 30 can be locked at any position with respect to the drawer storage frame 40 with one touch by moving the drawer 30 back and forth.

FIG. 7 shows still another example of the lock device. The lock device of this embodiment uses a push bolt type latch lock 80. This latch lock 80 is attached to the near side of the side frame 42 of the drawer storage frame 40. The latch lock 80 includes a cylinder 82, a bolt 84, a knob 85 provided at a base end of the bolt 84, a lock rod 86 which is a distal end of the bolt 84, and a not-shown inside the cylinder 82. A latch mechanism for holding the bolt 84 and a release button 87 for releasing the latch mechanism. This latch lock 80 pushes a knob 85 so that a lock rod 86 protrudes as shown by a chain line.
By pressing the release button 87 from above, the lock rod 86
Is retracted as shown by the solid line.

A plurality of receiving holes 88 are formed in the side wall 34 of the drawer 30 so as to correspond to the height position of the lock rod 86 along the longitudinal direction.

In order to move the drawer 30 back and forth to lock it at an arbitrary position with respect to the drawer storage frame 40, first, the release button 87 is pressed and the lock rod 86 is retracted.
The engagement between the lock rod 86 and the receiving hole 88 formed in the side wall 34 is released. Thereafter, the knob 85 is pushed at a desired position before and after the drawer 30 to engage the lock rod 86 with the desired receiving hole 88. Thus, the latch lock 80
By operating the knob 85 and the release button 87, the drawer 30 can be easily locked at a desired position.

[0030]

As described above, the keyboard storage drawer of the present invention is provided with a lock device which can lock and unlock at a desired position with a single touch. This has the advantage that the position can be fixed at a position that is easy to operate, and the keyboard operation can be performed stably.
