Claims

[Claims for Utility Model Registration] (1) A lock/release device that locks when pressed once and releases when pressed again, has a hollow cylindrical body and a cut provided on the outer periphery of the body. A swinging piece that is swingably supported in the notch with a rotating shaft as a fulcrum, a sliding projection provided on the swinging piece facing inward of the main body, and a hollow cylindrical shape that slides back and forth within the main body. a cam plate that slides left and right on the slider and has a cam that is combined with the sliding protrusion, and is attached between a spring seat provided on the main body and a spring seat provided on the slider. Consists of a compression spring,
Slopes are provided in the same direction at the front and rear of the sliding protrusion, and the cam is provided with a substantially heart-shaped central protuberance and edge portion having a contour that contacts the outer periphery of the sliding protrusion to determine a course. A circulation passage is formed, and the upper surface of the circulation passage is formed by combining a slope and a step, and the repulsive force of the compression spring exerts a rotational force on the swinging piece about the rotation axis as a fulcrum. The locking/releasing device is configured such that the sliding projection can slide on the upper surface of the circulation path of the cam while being pressed, and is formed so as to emit a falling sound when the sliding projection passes through the stepped portion. (2) The cam guides the sliding protrusion, which advances longitudinally on the circulation passage, to one side edge of the circulation passage, so that the cam has a direction of the slope of the sliding protrusion and an inclined portion that first contacts the sliding protrusion during the locking operation. the central raised part formed in the same direction as the central raised part, and the sliding protrusion that is located between the central raised part and the one side edge and touches the entire bottom surface of the advancing sliding protrusion so that its bottom surface does not exceed the top surface of the central raised part. In order to float to a higher height, there is an upward slope toward the receiving direction of the sliding protrusion, and the front edge of the guide slope is formed in the front end of the central raised part and consists of two peaks and one valley in a sawtooth shape. A first surface cam with a trapezoidal profile that ends on an extension line toward one side edge of the guide slope near one side edge, and a first surface cam with a trapezoidal outline that is adjacent to the front end of the first cam and is connected to the guide slope near the one side edge and one side edge. 2. The locking/releasing device according to claim 1, further comprising a second surface cam bent in an L-shape that widens toward the front and is lower than the height of the first cam.
