Elevator load bearing termination assembly with gripping inserts
First Claim
1. A device for securing an end of an elongated load bearing member in an elevator system, comprising:
- a first socket portion;
a second socket portion that is secured to the first socket portion;
a wedge that is at least partially received between the socket portions such that some of the elongated load bearing member is received between the socket portions and the wedge;
a first insert member that is at least partially received between the first socket portion and the wedge such that a corresponding portion of the load bearing member is secured between the wedge and the first insert member; and
a second insert member that is at least partially received within the second socket portion such that another portion of the load bearing member is secured between the wedge and the second insert member, the insert members having an alignment surface that faces opposite a load bearing member engaging surface and that directly engages and cooperates with a corresponding alignment surface on the respective socket portions such that the insert members automatically move into an alignment with the wedge that provides a uniform distribution of pressure on the corresponding portions of the load bearing member.

Abstract
A device for securing an end on a load bearing member in an elevator system includes a socket, a wedge and at least one insert member. The socket at least partially receives the insert member and wedge to maintain the end of the load bearing member in position. The preferred arrangement includes two insert members that engage the load bearing member on opposite sides of the wedge such that the load bearing member is gripped between the wedge and the insert members. The insert members and the socket preferably include contoured surfaces that facilitate arranging the engaging surfaces on the inserts in a parallel alignment to most evenly distribute pressure on the load bearing member.

5. A device for securing an end of an elongated load bearing member in an elevator system, comprising:
-
a socket;
a wedge that is at least partially received within the socket such that a first portion of the elongated load bearing member is received between the socket and the wedge; and
at least one insert member that is at least partially received within the socket such that a second portion of the load bearing member is secured between the wedge and the insert member, the insert member having an engaging surface that engages one side of the second portion of the load bearing member and an oppositely facing contoured surface that is received directly against a correspondingly contoured surface on the socket with a clearance between the socket and the insert member that allows the insert member to move laterally relative to a length of the second portion of the load bearing member in a manner that positions the insert member in alignment with the wedge. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method of securing an end of an elongated load bearing member in an elevator system using a socket, at least one insert and a wedge, comprising the steps of:
-
positioning a portion of the load bearing member about an exterior surface on at least a portion of the wedge;
positioning only one side of the insert against a portion of the load bearing member such that the portion of the load bearing member is positioned between the wedge and the insert, including positioning one insert against the load bearing member on one side of the wedge and a second insert against the load bearing member on an opposite side of the wedge; and
placing at least a portion of the wedge and at least a portion of the insert within the socket such that an oppositely facing side of the insert directly engages a corresponding surface on the socket and the insert becomes aligned with the wedge and such that the load bearing member is maintained in a selected position relative to the socket and wedge. - View Dependent Claims (21, 22)

23. A device for securing an end of an elongated load bearing member in an elevator system, comprising:
-
a socket;
a wedge that is at least partially received within the socket such that some of the elongated load bearing member is received between the socket and the wedge;
at least one insert member that is at least partially received within the socket between the socket and a surface on a corresponding portion of the load bearing member such that the corresponding portion of the load bearing member is secured between the wedge and the insert member; and
at least one holding member that cooperates with the insert member to maintain the insert member in a first position within the socket, the insert member having a boss with an opening and the holding member having a stem portion that is received at least partially within the boss opening and wherein the socket includes an opening through which at least a portion of the boss extends when the insert is held in the first position within the socket.

24. A device for securing an end of an elongated load bearing member in an elevator system, comprising:
-
a socket;
a wedge that is at least partially received within the socket such that a first portion of the elongated load bearing member is received between the socket and the wedge; and
at least one insert member that is at least partially received within the socket such that a second portion of the load bearing member is secured between the wedge and the insert member, the insert member having an engaging surface that engages one side of the second portion of the load bearing member, the engaging surface having grooves aligned perpendicular to a length of the second portion of the load bearing member, and an oppositely facing contoured surface that is at least partially rounded and has a radius of curvature that is perpendicular to the length of the second portion of the load bearing member, the contoured surface is received directly against a correspondingly contoured surface on the socket in a manner that positions the insert member in alignment with the wedge.
