Abstract

Ladder components, such as braces, as well as ladders and methods of manufacturing ladders are provided. In one embodiment, a ladder brace is provided which extends between a rail and a cross member (e.g., a rung or a cross-brace). The ladder brace may include a first connecting portion associated with the rail, a second connecting portion associated with the cross member, and a strut portion extending between the first and second connecting portions. At least one of the first connecting portion and the second connecting portion is configured to completely encircle its associated component (e.g., either the rail or the cross member, respectively).

First claim

What is claimed is:

1. A ladder comprising:
a first rail, a second rail spaced apart from the first rail, and at least one member extending between and coupled to the first rail and the second rail;
a first foot coupled to a lowermost portion of the first rail;
a brace having a first connecting portion coupled with the first rail, a second connecting portion coupled with the at least one member, and a strut portion extending between, and connected to, the first connecting portion and the second connecting portion, wherein the first connecting portion includes a tubular configuration that encircles a portion of the first rail at a location between the first foot and the at least one member;
wherein the brace, including the first connecting portion, the second connecting portion and the strut, is formed as a unitary member; and
wherein the first connecting portion is not fastened to the first rail by mechanical fastener or by adhesive.

2. The ladder of claim 1 , wherein the second connecting portion includes a tubular configuration that encircles a portion of the at least one member.

3. The ladder of claim 2 , wherein the first connecting portion maintains a sliding relationship with first rail and wherein the second connecting portion maintains a sliding relationship with the at least one member.

4. The ladder of claim 2 , wherein the second connecting portion is not fastened to the at least one member by mechanical fastener or by adhesive.

5. The ladder of claim 1 , wherein the at least one member includes a ladder rung.

6. The ladder of claim 1 , wherein the at least one member includes a cross-member.

7. The ladder of claim 1 , wherein the second connecting portion includes at least one flange, wherein the at least one flange is coupled with the at least one member.

8. The ladder of claim 7 , further comprising a mechanical fastener coupling the at least one flange with the at least one member.

9. The ladder of claim 1 , wherein the first connecting portion maintains a sliding relationship with first rail.

10. The ladder of claim 1 , wherein the tubular configuration conformally engages the exterior surface of the first rail.

11. The ladder of claim 1 , wherein the first rail exhibits a C-shaped cross-sectional profile having a web member and two flange members, and wherein the first connecting portion includes an abutting projection that extends into contact with the web member.

12. The ladder of claim 1 , further comprising:
a second foot coupled to a lowermost portion of the second rail;
a second brace having:
a first connecting portion coupled with the second rail,
a second connecting portion coupled with the lowermost rung, and
a strut portion extending between, and connected to, the first connecting portion and the second connecting portion, wherein the first connecting portion includes a tubular configuration that encircles a portion of the second rail at a location between the second foot and the at least one member.
