Abstract
A glass door leaf for elevator shaft and car doors has a glass pane connected at its lower edge with a guide shoe plate and at its upper edge with a hanger bracket. Eccentric pins with guide shoes are attached to the guide shoe plate and enter into a threshold profile for the sliding guidance of the glass door leaf at its lower end along the displacement path of the door. The glass pane is retained at the lower end between a lower base strip and a glass-retaining strip of the guide shoe plate and retained at the upper end between an upper base strip and the hanger bracket. Rubber bushings extend through apertures formed in the glass pane and encompass fastening nuts which are inserted from the elevator shaft side and are connected with welding pins attached to the base strips. A carrier holds a guide rail which extends along the displacement path and engages rollers which carry the glass door leaf and are mounted on the hanger bracket. A raised collar formed on each roller edge assures a secure guidance and prevents the glass door leaf from jumping off the guide rail.
