ABSTRACT:
An elevator connection (22) is provided for joining an elevator car (10) to a hydraulic piston (20) which raises and lowers the elevator car (10). Misalignment between the hydraulic piston (20) and guide rails (14) of an elevator shaft (12) is accommodated by a washer assembly (28) and cushion assembly (30) disposed between a stud bolt (32) and the top of the hydraulic piston (20). Washer assembly (28) includes an elastomeric disc (34) together with springs (36) which enclose a tubular washer (42) having a convex lower end surface. Cushion assembly (30) comprises an elastomeric disc (46) with springs (48) on either side thereof and enclosing a wobble tube (54) having convex end surfaces (56, 58). The elevator car (10) is held securely to the hydraulic piston (20) but is permitted to offset slightly from the piston (20) and tilt to accommodate misalignment of elevator guide rails (14) with the hydraulic piston (20).
