Abstract
A device for securing an end on a load bearing member in an elevator system includes a socket portion and a wedge portion. The socket and wedge preferably are made from an extruded piece of metal or a formed piece of sheet metal material. A brace member secures the wedge within the socket portion to maintain the wedge, and the corresponding portion of the load bearing member in place within the socket portion. The preferred arrangement includes friction enhancing surfaces on the corresponding portions of the socket and the wedge to facilitate maintaining the load bearing member in place.
Claims26
A device for securing an end of an elongated load bearing member in an elevator system, comprising:
- a socket portion having oppositely facing engaging surfaces inside the socket portion;
- a wedge portion that is at least partially received within the socket portion such that a portion of the elongated load bearing member is received between the engaging surfaces of the socket portion and the wedge portion;
- and
- at least one brace member that secures the wedge portion within the socket portion where the brace member has an engaging surface on an inside of the brace member and the socket portion includes a cooperating engaging surface on an outside of the socket portion for holding a section of the load bearing member between the socket portion outside engaging surface and the brace member inside engaging surface.
