Claims

[Scope of utility model registration request]

(1) The axle of the wheel and the rib, which extends in the radial direction of the wheel and is provided on the side surface of the wheel and is formed so that relatively protruding protruding parts and other non-protruding parts are distributed in the radial direction, When the engaging shafts arranged in parallel move in the radial direction of the wheel, and as a result of this movement take a position facing the protruding part, the wheel comes to a stopped state, and when it takes a position facing the non-protruding part. In a wheel stop device that allows wheel rotation, the rib and the engagement shaft are provided in relation to left and right wheels, respectively, and each of the engagement shafts is biased by a spring in a direction that brings the wheel to a stop state. and are configured to be connected to each other by wires to interlock, and a direction changing means is provided in the middle of the interlocking path by the wires for directing the operating direction of each tip of the wires in the same direction, thereby A wheel stopping device characterized in that when one engagement shaft moves in the radial direction of the wheel, the other engagement shaft moves B in the same radial direction of the wheel.

(2) In one wheel stopping device, a fixture is fixedly provided on the bearing side of the wheel, and the fixture is located on the fixture at a position corresponding to a protruding portion and a non-protruding portion of the rib, respectively. First and second engaging recesses are formed for receiving and positioning the retaining shaft, and the direction in which the elongated hole extends is formed by the combination of the guide elongated hole and the guide shaft that fits into the elongated hole. displacement and said guide shaft)
An operating member that can freely rotate is held, and the engagement shaft is held at one end of the operating member, and displacement of the operating member in the direction in which the elongated hole extends causes the engagement shaft to move to the second position. When the operating member moves in and out of the first or second engagement recess and rotates around the guide shaft, the engagement shaft moves between the first and second engagement recesses, and the engagement shaft moves in and out of the first or second engagement recess. is the first
When the engagement shaft engages with the second engagement recess, the engagement shaft engages with the protruding portion of the rib to maintain the wheel stopped state, and when the engagement shaft engages with the second engagement recess, the The engaging shaft faces the non-projecting portion of the rib but does not engage, resulting in the wheel rotation permissible state, and the direction changing means is provided on the fixture. The wheel stop device according to claim 1, which is a pulley around which the wire is wound.

(3) The direction changing means includes a rotatably provided disk, and two points in the middle of the wire are connected to two points on the disk that are substantially diametrically opposed to each other. A wheel stop device according to scope 1.
