Abstract: A step unit including a vertical frame and a plurality of linkages pivotally attached at different heights to the vertical frame by one end of each of the linkages, to provide lateral rotation to the linkages. A leg frame, with at least one leg, is pivotally attached to the opposite end of each linkage whereby laterally translating the leg frame simultaneously pivots the linkages from a first, vertical position to at least one second, horizontal position.

Abstract: The device is composed of a structure that comprises four inter-hinged modules (1-2-3-4), which enables multiple mounting possibilities thereof. Each module is formed of two essentially straight lateral bars (15-15?) that incorporate a pair of inwardly curved sections (17), which act as links between the two lateral bars in such a way that the end of each module ends in a pair of legs in the form of forks (18), which in turn end either in support legs (19) of the device, or in a hinging means (16), it having been provided that a series of adjustable and non-essential crossbars (20-20?-20?) are subject to being inserted into place in a center of the frame defined by the lateral bars (15-15?). The device is complemented by a series of accessories that make it possible to significantly increase the diverse types of exercises that may be carried out with the same.

Abstract: Ladders, ladder components and related methods are provided. In some embodiments, adjustable stepladders are provided which include locking mechanisms that enable height adjustment of the ladder through application of a force towards the rails of the ladder. In other embodiments, spreader mechanisms are provided with cross bracing located and configured to provide additional stability to the ladder while also incorporating a handle that enables efficient collapsing of the ladder while reducing the potential of pinching ones hands or fingers. In another embodiment, a device is provided for selective coupling with the ladder that includes a support or safety rail and an adjustable tray. The device may be coupled with the ladder in a number of different positions including a stowed position. In another embodiment, a hinge assembly is provided having a magnetic component configured to be magnetically coupled with and temporarily store an object on the ladder.

Abstract: A step unit includes right and left step frames and two steps coupled to the right and left step frames.

Abstract: A stepladder includes a longer inclined frame provided with steps coupled to a shorter stabilizer frame provided with rungs for movement relative to the longer inclined frame between an expanded use position and a collapsed storage position. The stepladder also includes a top-step lock to lock the top step in a fixed position relative to the two frames.

Abstract: A ladder comprises a foldable frame, a leg spreader, and a leg brace. The leg brace biases leg units of the frame toward one another to stiffen the frame in response to spreading of the leg units away from one another to an unfolded position by the leg spreader.

Abstract: A ladder safety crosspiece for inhibiting the diagonal movement of opposite (diagonal) legs of opposing rails of a stepladder. The crosspiece has a pair of crossing pliable stabilizers which extend between these diagonal legs, are taut as the side spacers of the ladder are locked, and which fold out of the way when the side spacers of the ladder are not locked and the ladder is folded.

Abstract: First and second ladder sections are each molded of a rigid plastics material, and each ladder section includes parallel spaced elongated leg portions integrally connected by two parallel spaced step portions. The ladder sections are pivotally connected by pins extending through overlapping laterally projecting ears and move between a collapsed position with the ladder sections adjacent and an extended aligned position where the second ladder section is supported by the first ladder section. The leg portions of the second ladder section define longitudinally extending cavities which receive corresponding elongated arms pivotal to generally horizontal positions adapted for seating on a motor vehicle tire. The arms also releasably connect with the leg portions of the first ladder section to position the ladder sections in the form of a short A-shaped step ladder.

Abstract: A platform stool is provided including a frame having a front leg and a rear leg. The front leg is pivotably coupled to the rear leg for movement about a leg pivot axis between an opened position and a closed position. The platform stool includes a multi-part platform including a front section pivotably coupled to the front leg and a rear section pivotably coupled to the rear leg, each of the front and rear sections having a top surface. A platform support linkage couples the front section to the rear section for movement about a platform pivot axis between a platform-forming position wherein the top surface of the front section and the top surface of the rear section are aligned in substantially coplanar relation to form a platform and a platform-collapsing position wherein the top surface of the front section faces away from the rear leg and the top surface of the rear section faces away from the front leg.

Abstract: A ladder conversion kit for converting an extension ladder into a stepladder. The kit includes one or more pairs of support braces for holding the two ladder elements together to form the stepladder. In a first embodiment, there is a top pedestal unit with a supporting surface and four sleeves with clamps that hold the pedestal onto the side rails of the ladder elements. In a second embodiment, the pedestal has four slots in the supporting surface, through which the upper ends of the side rails fit, and bungee straps are attached to the supporting surface and hook onto rungs of the ladder elements. In a third embodiment, there is no pedestal, and the ladder elements are held together solely by the support braces. The support braces may clamp onto the side rails or rungs of the ladder elements, or, if the rungs are hollow, they may be attached to rods inserted through the rungs.

Abstract: Combination step, stair well and extension ladders are characterized by a single bracket member by which a bucket rack and the top rear section are pivoted to the front step section, the bucket rack is supported by telescoping channel members, spring-biased hooks are pivoted on the top rear section to make locking engagement with the top step of the ladder's front step section and snap pin units are carried by brackets on the lower rear section to interlock with holes in the sides of the top rear section to adjust the length of the ladder when it is in the extension ladder configuration.
