Abstract

A socket device (10) for securing an end of a load bearing member (22) includes first socket members (26a and 26b) and second socket members (28a and 28b) that are distinct, separate pieces of material. The second socket members (28a and 28b) are spaced apart from each other at a desired angle and rigidly secured on one side to one of the first socket members (26a) and on another side to the other first socket member (26b) to form the socket (24). A disclosed example includes cooperating tabs (38) and recesses or openings (34) for securing the socket members together in a rigidly fixed alignment.

Claims

1. A socket for securing an end of an elongated load bearing member comprising:

two first socket members each comprising a separate and distinct piece that at least partially form a socket; and

two second socket members each comprising a separate and distinct piece, the second socket members are spaced apart from each other for receiving a load-bearing member between the second socket members, and each second socket member is rigidly fixed to at least one of the two first socket members.

2. The socket device as recited in claim 1, wherein each of the two first socket members are rigidly fixed to each of the two second socket members.

3. The socket device as recited in claim 2, wherein the two first socket members are parallel to each other.

4. The socket device as recited in claim 1, wherein the two second socket members are perpendicular to the at least one of the two first socket members.

5. The socket device as recited in claim 1, wherein the two first socket members each comprise a locking feature and the two second socket members each comprise a corresponding locking feature to secure the two second socket members to the two first socket members.

6. The socket device as recited in claim 5, wherein the locking feature comprises at least one recess that extends at least partially into each of the two first socket members and the corresponding locking features comprise at least one tab that extends from each of the two second socket members and is received at least partially within the recesses.

7. The socket device as recited in claim 6, wherein the recesses of at least one of the two first socket members comprise first openings arranged along a first plane and second openings arranged along a second plane and that is transverse to the first axis.

8. The socket device as recited in claim 7, wherein the first plane and the second plane form an angle of about 15°

.

9. The socket device as recited in claim 7, comprising a wedge for insertion between the second socket members, the wedge having an associated wedge angle that is different from an angle between the first plane and the second plane

10. The socket device as recited in claim 9, wherein the wedge angle is greater than the angle between the first plane and the second plane.

11. The socket device as recited in claim 10, wherein the wedge angle is ½

°

greater than the angle between the first plane and the second plane.

12. The socket device as recited in claim 6, wherein the recesses each include an opening having a peripheral surface and the tabs include beveled ends that form channels with the peripheral surfaces.

13. The socket device as recited in claim 12, comprising a welded connection at the channels.

14. The socket device as recited in claim 6, wherein at least one of the tabs comprise a rectangular protrusion.

15. The socket device as recited in claim 1, wherein the two first socket members include a connector opening that receives at least a portion of a connector member for connecting the socket to a support.

16. The socket device as recited in claim 15, wherein the connector opening includes a peripheral surface and the connector member includes a beveled end that forms a channel with the peripheral surface.

17. The socket device as recited in claim 1, comprising fasteners that secure the first socket members and the second socket members together.

18. The socket device as recited in claim 17, wherein the fasteners extend at least partially into one of the two second socket members.

19. The socket device as recited in claim 18, wherein the fasteners extend entirely through the one of the two second socket members.

20. A method of making a socket for use in an elevator system using two first socket members that at least partially form the socket, and two second socket members, wherein the first socket members and second socket members are all separate, distinct pieces, comprising:

rigidly fixing each of the two second socket members to each of the two first socket members to at least partially form a socket between the two second socket members.

21. The method as recited in claim 20, including inserting a plurality of tabs that extend from the two first socket members or the two second socket members into a corresponding plurality of recesses in the other of the two first socket members or the two second socket members to rigidly secure the two first socket members and the two second socket members together.

22. The method as recited in claim 21, including welding together the plurality of tabs and the corresponding plurality of recesses.

23. The method as recited in claim 21, including inserting a positioning member between the second socket members to achieve a spacing between the second socket members that is equal to a combined size of a wedge and a load-bearing member.

24. The method as recited in claim 23, comprising achieving a desired alignment of the second socket members corresponding to a configuration of the positioning member.

25. The method as recited in claim 23, including clamping the positioning member between the second socket members.

26. The method as recited in claim 21, including inserting first tabs of the plurality of tabs that extend from each of the two second locking members into first recesses of the plurality of recesses within the two first socket members.

27. The method as recited in claim 20, including rigidly fixing the two second socket members at an angle relative to each other and perpendicular to the two first socket members.

28. A socket made by the method recited in claim 20, wherein the two first socket members and the two second socket members comprise at least four distinct, separate pieces, the two second socket members are spaced apart from each other for receiving a load-bearing member between the two second socket members, and each of the two second socket members is rigidly fixed to each of the two first socket members.
