Claims

[Scope of Claim for Utility Model Registration] (1) In a rail switching device in which stationary rails are connected by rotating rails at intersections to form a continuous rail, a shaft is erected at the intersection of the rails, The center of the rotating rail is supported on the lower end of the shaft, and the center of the rotating plate is fixed on the upper end, and the middle of the lever is mounted on a pivot located directly above the stationary rail, and the lever is inserted into the lower end of the shaft. Attach a cam follower that engages with a moving trolley, etc., connect the upper end of the lever and the pivot point on the outer periphery of the rotating plate with a rod, and insert a coil spring between the spring set pin on the outer periphery of the rotating plate and the frame. The setting pin crosses the neutral line of the coil spring just before the cam follower is disengaged from the trolley, etc., and then the spring's elastic force moves the rotation rail to the fixed mounting position of the coil spring and the pivot joint. An automatic cross rail switching device characterized by having a fixed position such that the rails are rotated to a connecting position. (2) The intersecting rail automatic switching device according to claim (1), wherein one set of a pivot, a lever with a cam follower, a pivot joint, and a rod is arranged directly above the stationary rail of each intersecting rail. (3) One set of a pivot, a lever with a cam follower, a pivot joint, and a rod are arranged directly above both parts of the fixed rail that form a continuous rail to be connected, and one set of the 2. The cross rail automatic switching device according to claim 1, wherein when one cam follower is in a position where it engages with the trolley, the other cam follower is in a position where it does not engage.
