A ladder stabilizer is provided, comprising an extension bar portion, a main arm portion, a brace bar portion, teeth strips, and levers. The extension bar portion is enclosed by an outer wall surface, an inner wall surface, and two side wall surfaces, and having upper and lower end portions. The main arm portion has upper and lower end portions configured for a telescopic connection. The brace bar portion has first and second end portions, and the first end portion is connected to the side portion at a lower position, and the second end portion is connected to the extension bar portion at a middle position. The teeth strips are fixed to lower portions of the two side wall surfaces of the main arm portion. Each lever has latching and releasing ends, installed on the two side wall surfaces of the extension bar through two spring-loaded hinges.

The invention provides a tripod assembly comprising a plurality of legs, a central support member, and a central post. Each of the legs is pivotably coupled to the central support member. The central support member surrounds the central post. A plurality of columns is disposed in a nested arrangement for relative axial movement in a telescopic fashion along an axis of the plurality of columns between a fully-extended position and a collapsed position. The columns are received in the central post when the columns are in the collapsed position. A first end of a connecting rod is coupled to one of the columns. A bracket assembly is coupled to a second end of the connecting rod and is configured to receive a rung of a ladder therein. A bracket member is coupled to an uppermost column and includes a channel configured to receive a second rung of the ladder therein.

A multipurpose ladder having a first inner section. The ladder has a first articulated hinge and a second articulated hinge. The ladder has a second inner section. The ladder has a first outer section. The ladder has a first locking bar. The ladder has a second outer section. The multipurpose ladder may have a plurality of brackets disposed about outer rails of the outer sections. The brackets provide support to each of the outer rails and strengthens them against bending forces so the rails can be thinner and of lighter weight. The ladder may have an ANSI duty rating of 1A or an ANSI duty rating of 1AA. A method for using a multipurpose ladder. A method for producing a multipurpose ladder.

A ladder stabilizer for step ladders and extension ladders. The ladder stabilizer is collapsible for storage. Additionally, the ladder stabilizer includes legs that are adjustable in length and pivotally secured to a rigid lateral support. The rigid lateral support also carries a step plate secured by a hinge to the lateral support. The step plate provides the point of engagement between the ladder stabilizer and a rung of the ladder.

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).

A ladder includes a ladder stabilization apparatus which includes implements for providing sideways support, front-back support, and a bridge to rest the ladder on a structure to be climbed, such that the ladder is stable when a user climbs the ladder facing away from the structure, and the bridge allows the user to climb out of the ladder on to the structure through the bridge. The bridge also allows the user to climb on to the ladder facing from the structure, facing away from the structure, while the ladder is stable when the user climbs down while acing away from the structure.

Provided is ladder having an extension leg movable longitudinally in first and second directions opposite one another, and a stabilizer arm pivotably coupled to and movable with the extension leg. The stabilizer arm is pivotable about an axis perpendicular to the first and second directions such that the stabilizer arm is rotated relative to the extension leg to contact a surface to stabilize the ladder in a sideways direction perpendicular to the first and second directions.
