摘要： The ladder convertible to a scaffold is a self-standing ladder that is able to convert into a scaffold. The self-standing ladder is constructed of two ladder members that are able to attach to and pivot with respect to one another via a removable cap. The two ladder members also attach to one another via a foldable platform, which provides support when the two ladder members are pivoted away from one another in a self-standing configuration. The two ladder members may be disconnected to one another, and held in parallel arrangement with respect to one another via the foldable platform. The foldable platform is able to span a scaffold length between the two ladder members in order to form a scaffold. A pair of guar members attach to the two ladder members to provide guide rails on opposing sides of the scaffold.

摘要： Improvements to the leg extension of an adjustable ladder leveler and, more generally, improvements to ladder legs. A shoe with a claw that folds to be parallel to the ladder leg and then slides upward with respect to the leg thereby becoming locked into position so that it cannot move away from being parallel so long as weight is applied on the ladder. If the shoe is on an extension, as the shoe slides up, it engages a safety bar that prevents release of the extension.

摘要： A ladder upon which a user climbs having a first rail. The ladder having a second rail. The ladder having rungs attached to the first and second rails upon which the user steps. The ladder having a first leveler attached to the first rail. The first leveler having a foot peg and a latch. When the user presses on the foot peg and the latch with the user's foot when the leveler is in an extended state, the first leveler moves into a retracted state. The ladder having a second leveler attached to the second rail. A method for a user to use a ladder. The method has the step of the user pushing with the user's foot against a foot peg and latch of a first leveler to cause the first leveler to move to a retracted state relative to a first rail of the ladder in which the first leveler is. There is the step of the user pushing only against the foot peg but not the latch with the user's foot when the leveler is in the retracted state causing the first leveler to move to an extended state relative to the first rail and be maintained in the extended state. A leveler which positively prevents inadvertent retraction of the leveler from an extended state to a retracted state. A ladder having a module with a first and second ladder leveler.

摘要： Ladders, ladder components, adjustment mechanisms and related methods are provided herein. In one embodiment, a ladder may include an adjustment mechanism for adjusting, for example, a leveler, a stabilizer, or any two relatively displaceable components of the ladder. The adjustment mechanism may include an actuating mechanism having a first structure and a second structure slidably disposed adjacent the first structure, the second structure having a plurality of engagement surfaces. A body is coupled with the first structure. At least two engagement pins are slidably displaceable relative to the body, wherein the plurality of engagement surfaces and the at least two engagement pins are arranged such that only a single engagement pin of the at least two engagement pins is in abutting engagement with an engagement surface of the plurality of engagement surfaces at one time. At least one biasing member is configured to bias the at least two engagement pins towards engagement with the engagement surfaces.

摘要： A stabilized ladder assembly stabilizes a ladder by providing support on both sides of the ladder. The assembly includes a ladder having a first front side rail, a second front side rail, a first support leg, a second support leg and a plurality of rungs coupled to and extending between the first and second front side rails. A pair of support bars is provided. One of the support bars is coupled to and extends between the first front side rail and the first support leg. One of the support bars is coupled to and extends between the second front side rail and the second support leg. A cross member is coupled to and extends between the support bars. A pair of base supports is provided and each is configured to contact a ground surface. Each of the base supports is coupled to and extends downwardly from the cross member.

摘要： An assembled ladder is formed by coupling a top ladder segment, a plurality of middle ladder segments, and a plurality of bottom ladder segments together. The bottom ladder segments include a ladder body, support frame assemblies, ancillary frames, adjustable support pads, and adjustable coupling members. The support frame assemblies are respectively set at two sides of the ladder body. The ancillary frames are mounted to the support frame assembly. The adjustable support pads are screwed to the ancillary frames. The adjustable coupling members have an end coupled to the support frame assemblies and are partially received in the receiving space. With the adjustable coupling members fixing the support frame assemblies, the ancillary frames are expanded. Through adjustment made with the adjustable support pads, the ladder can be set more stably to achieve safety and convenience of use.

摘要： An automatic locking system for a self-adjustable leveling ladder engages when the ladder is placed on the ground and disengages when the ladder is lifted off the ground. The automatic locking system includes a clamping mechanism, a first support, and a second support. The clamping mechanism includes a first member, a second member, a central pivot, a pair of key plates, and a cross rail. The first support pivotally connects to the first member, and the second support pivotally connects to the second member. The first member hingedly connects to the second member by the central pivot, which allows the key plates to grasp the cross rail if the first support and the second support are pressed against the ground. The first member and the second member are able to slide along the cross rail, which properly adjusts the first support and the second support for an uneven ground surface.
