Claims

[Scope of utility model registration request]

In a safety device for a lane in which wheels run on horizontally installed rails, a weight at the lower end and a fan-shaped plate cam at the upper end are integrally connected via a connecting member and are arranged above the central axis of the wheels. a pendulum pivotally connected to the shaft support member of the wheel at the center of the plate cam so as to be able to swing freely on a plane perpendicular to the central axis of the wheel, with one end of the pendulum pivoted to the shaft support member of the wheel on a plane perpendicular to the central axis of the wheel; a spring that is locked at the upper end to keep the pendulum vertical; and a wedge at the lower end that can fit into the gap between the rail and the wheel at a position symmetrical to the vertical center plane of the wheel; a pair of arms that are connected by a link and whose middle portions are connected to the shaft supporting member below the plate cam so as to be able to swing freely on a plane perpendicular to the central axis of the wheel, and whose lower portions can be approached and separated; , a spring that is locked at one end to each of the pair of arms and biases the lower portions of the arms toward each other; and a roller that is detachably engaged with the plate cam and rotatably supported on the upper end. a roller support arm having a lower portion fixed to one of the pair of arms and separating the lower portions of the pair of arms from each other when the roller is in contact with a cam surface of the plate cam; A safety device for a running lane, comprising a vertical movement limiting member whose upper part is fixed to the shaft support member and whose lower part faces the lower surface of the running surface of the rail with a slight gap.
