Abstract

An elevator cab generally comprises a platform and a series of wall panels that make up the cab walls. A fastening assembly, used to connect the wall panels with the platform, comprises a stud and a retainer clip. The stud is connected to the wall panels and the retainer clip is connected with the platform. Furthermore, the stud and retainer clip engage without the use of tools in a manner that securely fastens the wall panels to the platform to thereby construct portions of the elevator cab.

Claims

1. An elevator car comprising:

(a) a platform comprising a plurality of holes;

(b) at least one wall, wherein the at least one wall connects to the platform;

(c) a male fastening member having an engaging portion; and

(d) a female fastening member comprising

(i) an aperture, wherein the aperture is oriented coaxially to one of the plurality of holes of the platform, and

(ii) a resilient engaging member, wherein the resilient engaging member defines the aperture, wherein the engaging member is configured to resiliently engage the engaging portion of the male fastening member to connect the at least one wall to the platform.

2. The apparatus of claim 1, wherein the female fastening member further comprises a slot, wherein the slot further defines the resilient engaging member.

3. The apparatus of claim 2, wherein the slot is tangentially positioned relative to the aperture.

4. The apparatus of claim 2, wherein the slot is orthogonally positioned relative to the aperture.

5. The apparatus of claim 1, wherein the male fastening member is secured to the at least one wall

6. The apparatus of claim 1, wherein the female fastening member is attached to the platform.

7. The apparatus of claim 1, wherein the plurality of holes are circular.

8. The apparatus of claim 7, wherein the holes are near a perimeter of the platform.

9. The apparatus of claim 1, wherein the male fastening member comprises an attachment portion and a collar, wherein the attachment portion and the collar form an interference fitting between the male fastening member and the at least one wall.

10. The apparatus of claim 1, wherein the engaging portion of the male fastening member is threaded.

11. The apparatus of claim 1, wherein the engaging portion of the male fastening member is generally smooth.

12. The apparatus of claim 1, wherein the engaging member is oriented substantially perpendicular relative to the male fastening member.

13. An elevator car fastening assembly comprising:

(a) a clip, wherein the clip is securely fastened to a platform of the elevator car, the clip comprising;

(i) at least one resilient tab, and

(ii) an aperture, wherein, the aperture is defined by the at least one resilient tab, and wherein the aperture is coaxially aligned with an opening in the platform; and

(b) at least one wall assembly comprising;

(i) a wall portion, and

(ii) a fastening member, having an end, wherein the end is locked in place by the at least one resilient tab when the fastening member is inserted into the aperture of the clip.

14. The apparatus of claim 13, wherein the fastening member further comprises at least one slot, wherein the slot further defines the resilient tab.

15. The apparatus of claim 14, wherein the slot is tangentially positioned relative to the aperture.

16. The apparatus of claim 14, wherein the slot is orthogonally positioned relative to the aperture.

17. The apparatus of claim 13, wherein the at least one wall is connectable to the platform during an installation without the use of tools.

18. The apparatus of claim 13, wherein the end of the fastening member is threaded.

19. The apparatus of claim 13, wherein the end of the fastening member is generally smooth.

20. A method of installing an elevator wall onto an elevator platform comprising:

(a) attaching a fastening member to the elevator wall with an engaging member of the fastening member protruding from the elevator wall;

(b) aligning a clip onto the elevator platform, wherein the clip has an aperture defined by at least two engaging members, wherein the elevator platform has a plurality of openings, wherein the clip is coaxially aligned with at least one of the openings on the elevator platform; and

(c) inserting the engaging member protruding from the wall into the coaxially aligned aperture and opening thereby resiliently locking the elevator wall to the elevator platform.
