[0002]

2. Description of the Related Art As disclosed in Japanese Utility Model Registration No. 3038926, in a conventional fastener device, an operation lever rotates up and down in a plane perpendicular to the front surface of one tightened member. I have.

However, in the conventional fastener device in which the operation lever rotates up and down as described above, it is necessary to secure a sufficient space in the space on the front side of the operation lever to allow the operation lever to rotate up and down. In some cases, such a space cannot be ensured depending on a mounting target of the fastener device or a use location.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to change the rotation direction of the operation lever to establish a temporary lock even if only a small space is secured in the front space of the operation lever. Can,
An object of the present invention is to provide a space-saving fastener device.

A fastener device according to the present invention will be described below with reference to the accompanying drawings. In the fastener device according to the present invention, a slider is provided on the front side of a base plate 2 fixed to the front side of one tightened member 1. The plate 3 is slidably fitted in the vertical direction, the upper end of the operating lever 4 is overlapped on the front side of the slider plate 3, and the operating lever 4 is moved by the shaft pin 5 passing through the vertical escape slot 20 of the slider plate 3. A box which is pivotally connected to the base plate 2 and rotatably connects the base end portion of the joint plate 7 to the bearing plate portion 23 connected to the upper portion of the slider plate 3 by the shaft pin 6 so as to be rotatable. The lower half of the catch rod 9 is movably penetrated through the hook 8 in the vertical direction, and the compression coil spring 16
As a result, the hook rod 9 is moved and urged in a direction of being drawn into the box portion 8, and is inserted into the receiving groove 13 a of the hook plate 13 of the metal receiving body 12 fixed to the front surface of the other tightened body 11. A lock hook portion 10 engaging the back side of the hook portion 13 is continuously provided at the upper end of the hook 9, a cam slot 14 intersecting with the escape slot 20 is provided on the slider plate 3 in the left-right direction, and a shaft is provided on the operation lever 4. The drive pin 15 is fixedly provided at a position away from the pin 5, and the drive pin 15 is fitted into the cam slot 14.

The hook rod 9 and the joint plate 7 are connected to the shaft pin 6.
And the hook rod 9 is inserted into the receiving groove portion 13a of the latch plate portion 13 of the metal receiving plate 12, and then the operation lever 4 is rotated about the shaft pin 5 in parallel with the front surface of the one clamped body 1. When it is rotated in a plane, the drive pin 15 fixed to the operation lever 4 pushes the inner wall surface of the cam slot 14 of the slider plate 3, so that the slider plate slides downward along the base plate 2, and the joint The plate 7 and the hook rod 9 are drawn toward one of the tightened bodies 1. At this time, the shaft pin 5 of the operation lever 4 apparently moves in the escape slot 20 of the slider plate 3.

A locking hook 10 at the tip of the hook rod 9
When the rotation of the operation lever 4 is continued even after the contact of the operating lever 4 with the back surface of the retaining plate portion 13, the movement of the retaining rod 9 is stopped, and only the joint plate 7 is further drawn toward the tightened body 1 side. Therefore, the compression coil spring 16 in the box portion 8 of the joint plate 7 is compressed, and the locking hook portion 10 is tightly engaged with the back surface of the locking plate portion 13, thereby tightening the two tightened members 1, 11. A temporary lock is established.

To release the tightening temporary lock, the operation lever 4 may be rotated in a direction opposite to the above. By this reverse rotation operation, the drive pin 15 pushes the inner wall surface on the opposite side of the cam slot 14, so that the slider plate 3
The joint plate 7 and the catch rod 9 connected to the slider plate 3 move upward along the
Pushed up to one side. As a result, the engagement between the locking hook portion 10 and the locking plate portion 13 is released, and the locking hook portion 10 moves to a position sufficiently distant from the metal plate 12,
The joint plate 7 and the hooking rod 7 can be raised and rotated about the shaft pin 6 in a plane perpendicular to the front surface of the tightened body 1. Since the hook rod can be detached from the receiving groove 13a of the hook plate 13 by the upright rotation,
The tightening temporary lock of the two tightened bodies 1 and 11 is released.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated embodiment, a base plate 2 is shown.
Is fixed to the front surface of one of the clamped bodies 1 by screws 21, and the metal receiving plate 12 is fixed to the other clamped body 11 by screws 22.
It is fixed to the front of. Guide plates 3 a are bent at the left and right ends of the slide plate 3, and the two guide plates 3 a are in contact with the left and right end surfaces of the base plate 2. The cam slot 14 of the slide plate 3 is provided symmetrically in a cross shape so as to cross the lower end of the escape slot 20, and the drive pin 15 of the operation lever 4 is provided directly below the shaft pin 5. . Therefore, regardless of whether the operation lever 4 is turned clockwise or counterclockwise, the slide plate 3 can be driven up and down. The rotation direction can be arbitrarily selected according to the restriction on the space to be mounted, and the usability is good.

The bearing plate portion 23 of the slide plate 3 is formed in a pair of right and left U-shapes, and the shaft pin 6 crossing in the left and right direction is fixed. The lower end 7a of the joint plate 7 is bent in a U-shape so as to wind the shaft pin 6. Openings 8a and 8b through which hook rods 9 are movably provided are provided in the upper frame wall and the lower frame wall of the box portion 8 of the joint plate 7. The lower end of the catch rod 9 has a flange 9a and a screw shaft 9b.
Is formed, and a nut 24 that cannot pass through the opening 8b is fitted to the screw shaft 9b. The compression coil spring 16 is inserted between the upper frame wall of the box 8 and the flange 9a. The hooking rod 9 is bent in a V-shape near the middle portion, and the locking hook portion 10 is formed in a T-shape.

The base plate 2 is provided with a shaft hole 18 into which the shaft pin 5 of the operation lever 4 is inserted. On the front side of the base plate 2, a semicircular ridge 19 centered on the shaft hole 18 is provided. It is formed. The edge surface of the semicircular raised portion 19 is a guide surface on which the drive pin 15 slides, so that stable rotation of the operation lever 4 is ensured. The lower end 20a of the escape slot 20 of the slide plate 3 is provided so as to penetrate the cam slot 14. When the tightening temporary lock is established, the driving pin 15 engages with the slot lower end 20a. The tablets are to be kept stable.

[0012]

As described above, in the fastener device of the present invention, the cam slot 14 is provided in the slider plate 3 in the left-right direction so as to intersect with the escape slot 20 of the shaft pin 5, and the operation lever 4 is separated from the shaft pin 5. The drive pin 15 is fixedly mounted at the position, the drive pin 15 is fitted into the cam slot 14, and the operation lever 4 is rotated about the shaft pin 5 in a plane parallel to the front surface of the tightened body 1, whereby the drive pin 15 is rotated. Since the slider plate 3 is slid in the vertical direction by pressing the inner wall surface of the cam slot 14 with 15, only a small space is left on the front side of the operation lever unlike the conventional device in which the operation lever rotates up and down. It can be used effectively even where there is no mounting.
