説明すると次の通りである。[Detailed Description of the Invention] The present invention relates to an operating lever mechanism for unlocking a telescopic member, that is, a gas spring, which is used to elastically move a movable member as appropriate in, for example, a bed, furniture, or various other devices. In contrast to the conventional mechanism in which the lock could be released only when the operating lever was rotated in one predetermined direction, the present invention allows the lock to be released regardless of the direction of rotation. This further improves operability. The present invention will be described in detail below based on examples.

It is divided by an operating piston 6 provided with an oil flow passage 5, an operating rod 7 is connected to the operating piston 6, and the oil flow passage 5 is connected to a lock valve 8.
When the lock valve 8 is in the open state, the lock valve 8 is released from the lock and the actuating rod 7 is elastically movable in the extending direction, and when the lock valve 8 is in the closed state, it is in the locked state. That is. The lock release rod 9 of the lock valve 8 is provided coaxially with the actuation rod 7, and a mounting frame B having a side plate portion 10 for holding the actuation lever 11 is attached to the end of the actuation rod 7, and the actuation lever 11 or A pair of protrusions 12, 12' are provided on one side of the side plate portion 10 and extend forward and backward in the length direction of the actuating lever 11, and each of the pair of protrusions 12, 12' is provided on the other side. By providing fitting holes 13, 13' that are movable in the rotational direction with 12' as a fulcrum, and fitting the pair of protrusions 12, 12' into the fitting holes 13, 13', the actuating lever 11 Side plate part 1

ができる。 However, in the state shown in FIG.
When an operating force is applied to move one end a to the left, the operating lever 11 rotates clockwise around the protrusion 12 on the one end a side as a fulcrum, as shown in FIG. Push the lock release rod 9. Furthermore, when one end a of the actuating lever 11 is moved to the right in the state shown in FIG. The lock release rod 9 is also rotated counterclockwise by the pushing part 15.
Push. In this way, the present invention uses the operating lever 11.
The lock release rod 9 can be pushed by rotating it in any direction. When the lock release rod 9 is pushed in this manner, the lock valve 8 is opened as shown in FIG. 4c, allowing oil to flow freely through the oil flow passage 5, and the operating piston 6 becomes movable.
Therefore, the actuating rod 7 is telescopic with respect to the cylinder 2, and the actuating rod 7 can be elastically extended or shortened against the elastic movement to move the actuating rod 7 as appropriate connected to the mounting frame 10. The member can be moved.
次に作動レバー１１から操作力を取り去ると、

る。 Next, when the operating force is removed from the operating lever 11,
The actuating lever 11 is biased by the spring 14 and returns to its original position as shown in FIG. 1, and the lock valve 8 also returns to its original closed state, so that the actuating rod 7 becomes unable to extend or contract again and fixes the moving member. It can be a state.

の他、各種装置に適用し得ることは勿論である。 FIG. 5 shows an example in which the mechanism of the present invention is applied to a mechanism for lifting and lowering the back plate of a bed, and this mechanism connects the mounting frame 10 to a mounting rod 17 provided on the underside of the back plate 16. together with the mounting piece 1 on the cylinder 2 side.
8 is connected to the mounting rod 20 of the floor plate support frame 19, and the operating lever 11 is connected to an operating lever 21 rotatably provided on the side near the head of the back plate 16, and the connecting arm 22, the connecting rod 23, etc. are operated. They are connected via a force transmission mechanism. In this configuration, when changing the back plate 16 from a horizontal state to an inclined state, or from an inclined state to a horizontal state, an operating force is applied to the operating lever 11 by rotating the operating lever 21 to close the lock valve. 8 must be opened, but the direction of the force will be more natural if the operating lever 21 is rotated in the same direction as the back plate 16 as shown by the arrow in the figure. and easy to operate. However, in the conventional gas spring, the lock can be released only when the operating lever is rotated in one predetermined direction, and therefore the operating lever cannot be operated in this manner. In contrast, in the present invention, as described above, the lock can be released by rotating the operating lever 11 either clockwise or counterclockwise, so the operating lever 21 can be moved in a direction that is easy to operate at all times. A major feature is that it can be manipulated. In addition, the operating lever 11
In addition to a configuration in which the rotation is performed by the operating lever 21 via an operating force transmission mechanism as in the illustrated example, the above feature is also exhibited in a configuration in which the operating lever 11 itself is rotated by operating it. Of course. It goes without saying that the present invention can be applied to various devices in addition to the above-mentioned mechanism for raising and lowering the floorboard of the bed.
