Hereinafter, embodiments of the tilt hinge with a lock function according to the present invention will be described with reference to the drawings.

1 and 2, 1 is a main body of an OA device such as a copying machine, 2 is a panel, 3 is a hinge fixing bracket attached to the main body 1 of the OA device, 4 is a hinge movable bracket attached to the panel 2, 5 is a tilt hinge, 6 is a hinge shaft, 7 is a ratchet tooth, 8 is a ratchet claw, 9 is a transmission mechanism, and 10 is an operation plate.

  The side plate 3a on one side of the hinge fixing bracket 3 and the side plate 4a on one side of the hinge movable bracket 4 are overlapped with each other and supported by a tilt hinge 5 with a predetermined friction torque. On the other hand, the other side plate 3 b on the other side of the hinge fixing bracket 3 and the other side plate 4 b on the other side of the hinge movable bracket 4 are overlapped with each other and supported by the hinge shaft 6.

The ratchet teeth 7 are integrally attached to the other side plate 3 b of the hinge fixing bracket 3 via the hinge shaft 6. The ratchet teeth 7 are formed in a so-called sawtooth shape. (See Figure 3)

As apparent from FIG. 3, the ratchet teeth 7 are selectively engaged with the ratchet teeth 7. The ratchet pawl 8 can be rotated around a shaft 8a. The shaft 8a is fixed to the side plate 4b on the other side of the hinge movable bracket 4. Therefore, the ratchet pawl 8 rotates around the hinge shaft 6, that is, along the ratchet teeth 7 as the panel 2 tilts.

The transmission mechanism 9 includes a passive member 9a, a transmission rod 9b, an operating member 9c, and a connecting rod 9d. A passive member 9a and an operating member 9c are integrally attached to both ends of the transmission rod 9. The actuating member 9c is connected to the ratchet claw 8 through the connecting rod 9d, and the ratchet claw 8 can be operated from the ratchet teeth 7 detachably as the operating member 9c rotates. It is like that.

As is clear from FIG. 2A, the passive member 9a is in contact with an operating rod 10a projecting from the operation plate 10. Therefore, the passive member 9a rotates with the movement of the operation plate 10 in the direction of arrow A, that is, the movement of the operating rod 10a in the direction of arrow A, and the operating member 9c rotates through the transmission rod 9b. Move.

As is clear from FIG. 3, a compression coil spring 11 is interposed between the operation plate 10 and the panel 2.

  Since the tilt hinge with a lock function of the present embodiment is configured as described above, when the operation plate 10 is positioned in the arrow B direction by the compression coil spring 11, as shown in FIG. Since the ratchet pawl 8 is engaged with the ratchet teeth 7 via 9, the panel 2 is in a locked state.

In this locked state, when the panel 2 is lifted in the direction of the arrow L and an attempt is made to rotate counterclockwise around the hinge shaft 6 in FIG. 3, the ratchet pawl 8 is disengaged from the ratchet teeth 7, The above rotation is possible. In other words, the ratchet pawl 8 can be rotated in one direction (one-way) by the saw-toothed ratchet teeth 7, and this rotatable direction is prevented by gravity and stable unless the panel 2 is lifted.

  Next, as shown in FIG. 4, when the operation plate 10 is pulled in the direction of arrow A against the compression coil spring 11, the ratchet pawl 8 is detached from the ratchet teeth 7 via the transmission mechanism 9. The locked state is released. In this state, the panel 2 is supported by hand, and can be lowered as it is. Of course, it is also possible to lift the panel 2 upward.

FIG. 5 shows another embodiment of the tilt hinge with a lock function according to the present invention. The main body 1 of the OA apparatus, the panel 2, the hinge fixing bracket 3, the side plates 3a and 3b, the hinge movable bracket 4, the side plate 4a and the like. 4b, the tilt hinge 5, the hinge shaft 6, the transmission mechanism 9, the passive member 9a, the transmission rod 9b, the operation member 9c, the operation plate 10, and the compression coil spring 11 have the same or substantially the same shape and function as the members of the first embodiment.

In FIG. 5, 12 is a roller clutch, which is usually an inner ring (not shown) fitted and fixed to the hinge shaft 6 and an outer ring 12 fixed to the side plate 4b on the other side of the hinge movable bracket 4. A roller (may be a ball: not shown) accommodated between the inner ring and the outer ring 12, a cage for holding the roller, and a cam surface and a recess formed in the outer ring 12 (or the inner ring). And a spring for urging the roller toward the cam surface, and the rotation of the outer ring 12 in one direction (one-way) or two directions (two-way) can be locked. Since the present invention is not a roller clutch invention, any conventional structure may be used.

In FIG. 5, 13 is an operating rod, which is a member for releasing the lock by releasing the engagement of the roller with the cam surface. Therefore, as shown in FIG. 6A, when the operation plate 10 is pulled in the direction of the arrow A, the lock is released by the operation rod 13 via the transmission mechanism 9. On the other hand, as shown in FIG. 6B, when the pulling operation of the operation plate 10 is released and the operation plate 10 is moved in the arrow B direction by the compression coil spring 11, the operation rod 13 is transmitted via the transmission mechanism 9.
