Abstract: 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.

Abstract: A rigid structure such as a ladder is disclosed having rotating hinges that allow the ladder to fold up and/or be disassembled and assembled. The hinge or hinges can be provided between ladder sections with one ladder section having a male hinge element, and another having a female hinge element. A cam element provided with the female hinge element can be moved between an unlocked position in which the ladder sections can rotate with respect to each other, and a locked position in which the structure is rigid.

Abstract: The utility model provides a thick-plate hinge for ladder jointing, comprising an inner plate and outer plates that are rotatably connected to each other; the thick-plate hinge further comprises a positioning shaft sleeve designed to lock up and position the inner plate and outer plates, the outer plate is provided with a stop stub designed to limit the relative rotation angle of the inner plate, the inner plate is provided with a slot designed to stop the stop stub. Compared to the prior art, when the thick-plate hinge for ladder jointing provided in the utility model is used on a ladder, the ladder will have improved bearing performance, and will be safer and more reliable. In addition, the present utility model is simple in structure, easy to manufacture, and low in cost.

Abstract: A foldable ladder has a first ladder portion and a second ladder portion hingedly attached to the first ladder portion by a pair of hinge mechanisms. Each hinge mechanism adapted to lock the first and second ladder portions such that the first ladder portion and the second ladder portion form an angle therebetween. The hinge mechanism has a shifting mechanism and a ladder angle selector coupled thereto to allow manual selection of the angle between the first and second ladder portions, and a locking pin to lock the first and second ladder portions at an angular 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: A locking mechanism for selectively securing and unsecuring the linkage of individual ladder sections of a telescopic ladder. The locking mechanism is shifted into a locked position by pivoting a lever toward a first rotational trajectory, urging a track follower in a first direction along a guiding track, and linearly displacing at least one securing rod into an aperture through multiple ladder sections, securing the linkage of the ladder sections. A lever-securing mechanism form-fittingly secures the lever within a bridge element of the locking mechanism when in a locked position. The locking mechanism is shifted into an unlocked position by pivoting the lever toward a second rotational trajectory opposite the first rotational trajectory, urging the track follower in an opposite direction along the guiding track, and linearly displacing the securing rods out from the aperture through the multiple ladder sections, unsecuring the linkage of the ladder sections.
