Abstract

A bracket for attaching a lifting/lowering device to a support member of a safety structure, the bracket including: a body configured to at least partially contact or envelop a support member of a safety structure, wherein at least one surface of the body has at least one cut-out that includes at least one shaped end for contacting a support member pin inserted into the support member of the safety structure, and wherein the body includes at least one surface for mounting or securing the bracket to a lifting/lowering device. A bracket and lifting/lowering device assembly and method of installation are also disclosed.

First claim

What is claimed is:

1. A bracket for attaching a device to a support member of a safety structure, the bracket comprising:
a body configured to at least partially contact or envelop a support member of a safety structure, the body comprising at least one surface for securing the bracket to the device,
wherein at least one surface of the body has at least one cut-out that includes an upper shaped end and a lower shaped end, at least one of the upper shaped end and the lower shaped end configured for contacting a support member pin inserted into the support member of the safety structure,
wherein the at least one cut-out has an open end on a peripheral edge of the at least one surface of the body such that the support member pin is insertable through the open end and into one of the upper shaped end and the lower shaped end, and
wherein the bracket is configured to slide upwardly on the support member to position the support member pin at least partially in the lower shaped end of the at least one cut-out.

2. The bracket of claim 1 , wherein the body has at least two surfaces configured to contact the support member of the safety structure.

3. The bracket of claim 1 , wherein the body is shaped to substantially conform to at least a portion of the shape of the support member of the safety structure.

4. The bracket of claim 1 , wherein the at least one cut-out is positioned substantially centrally on the peripheral edge of the at least one surface of the body.

5. The bracket of claim 1 , wherein at least one of the upper shaped end and the lower shaped end is rounded.

6. A bracket and device assembly for use with a safety structure, comprising:
a bracket comprising a body configured to at least partially contact or envelop a support member of a safety structure, wherein at least one surface of the body has at least one cut-out that includes an upper shaped end and a lower shaped end, at least one of the upper shaped end and the lower shaped end configured for contacting a support member pin inserted into the support member of the safety structure, wherein the at least one cut-out has an open end on a peripheral edge of the at least one surface of the body such that the support member pin is insertable through the open end and into one of the upper shape end and the lower shaped end, the body comprising at least one surface for securing the bracket to a device;
the device; and
the support member of the safety structure;
wherein the support member includes at least two segments arranged telescopically together and secured together by inserting a support member pin into mounting holes of the segments, and
wherein the bracket slides upwardly on the support member to position the support member pin at least partially in the lower shaped end of the at least one cut-out.

7. The bracket and device assembly of claim 6 , wherein the body has at least two surfaces configured to contact the support member of the safety structure.

8. The bracket and device assembly of claim 6 , wherein the body is shaped to substantially conform to at least a portion of the shape of the support member of the safety structure.

9. The bracket and device assembly of claim 6 , wherein the at least one cut-out is positioned substantially centrally on the peripheral edge of the at least one surface of the body.

10. The bracket and device assembly of claim 6 , wherein at least one of the upper shaped end and the lower shaped end is rounded.

11. The bracket and device assembly of claim 6 , wherein the support member pin includes an attachment member for securing the support member pin to the support member of the safety structure.

12. A method of installing a bracket and device assembly on a support member of a safety structure, comprising:
(i) installing at least a portion of a support member pin into a mounting hole of a support member of a safety structure;
(ii) mounting a bracket and device assembly to the support member; wherein the bracket and device assembly comprises:
a bracket comprising a body configured to at least partially contact or envelop a support member of a safety structure, wherein at least one surface of the body has at least one cut-out that includes an upper shaped end and a lower shaped end, at least one of the upper shaped end and the lower shaped end configured for contacting or surrounding at least a portion of a support member pin inserted into the support member of the safety structure, wherein the at least one cut-out has an open end on a peripheral edge of the at least one surface of the body such that the support member pin is insertable through the open end and into the shaped end, and wherein the body comprises at least one surface for securing the bracket to a device;
the device; and
the support member of the safety structure, wherein the support member includes at least two segments arranged telescopically;
(iii) sliding the bracket and device assembly upwardly on the support member to allow the support member pin to slide at least partially into the lower shaped end of the at least one cut-out of the bracket; and
(iv) further inserting the support member pin through at least one mounting hole of the support member and a hole on a portion of the device.

13. The method of claim 12 , wherein the body has at least two surfaces configured to contact the support member of the safety structure.

14. The method of claim 12 , wherein the body is shaped to substantially conform to at least a portion of the shape of the support member of the safety structure.

15. The method of claim 12 , wherein the at least one cut-out is positioned substantially centrally on the peripheral edge of the at least one surface of the body.

16. The method of claim 12 , wherein at least one of the upper shaped end and the lower shaped end is rounded.

17. The method of claim 12 , wherein the support member pin includes an attachment member for securing the support member pin to the support member of the safety structure.
