Claims

[Claims for Utility Model Registration] 1. A pair of X-shaped parallel telescoping mechanisms are rotatably attached to the left and right sides of a base frame, with one lower end rotatably attached to the other end of the base frame. The end is slidable along the base frame, and a platform is placed on top of the X-shaped parallel telescoping mechanism, and one end of the upper side of the X-shaped parallel telescoping mechanism is rotated to the end of the back surface of the platform. In addition to being freely pivotable, the other end of the upper side of the X-shaped parallel telescoping mechanism is slidably provided on the back surface of the other end side, and the X-shaped parallel telescoping mechanism is opened and closed by a drive means to raise and lower the platform. In the elevator that
a rack member provided to the upper edge of the base frame between the other lower end of the X-shaped parallel expansion and contraction mechanism and the base frame;
A locking mechanism is provided to lock the rack member, and a locking member is attached to the other lower end of the X-shaped parallel telescoping mechanism, and the locking mechanism is configured to perform a parallel crank movement with respect to the rack member. A push-up bar is provided that allows the locking mechanism to be unlocked by pushing up the locking member and moving it away from the rack, and the push-up bar is stopped at a lock release position where the locking member moves away from the rack. In addition to providing a stopper, the push-up bar is in a position where the push-up bar releases the locking mechanism,
Just before the platform reaches its lowest position, it comes into contact with the outer periphery of the wheel provided at the other lower end of the X-type parallel telescoping mechanism above the axle, and in the position where the push-up bar is located at the top dead center, Similarly, a safety device for an elevator is characterized in that a contact element is attached to a portion of the outer periphery of the wheel that comes into contact with a portion below the upper end of the wheel. 2. The safety of the elevator as set forth in claim 1 of the utility model registration claim, wherein the contact is a single plate-shaped body whose tip abuts against the outer periphery of the wheel within a range directly above and directly beside the axle. Device.
