摘要： A foldable stairway ladder for use in accessing items includes a structure that can be conveniently folded to reduce the amount of space taken up by ladder when not in use. The ladder consists of a stairway section connected to a platform, in turn rotatably connected to a support. The foldable ladder is also provided with a manually operable folding system adapted to fold the stairway section and support relative to each other. Additionally, the support may have a member capable of extending the length of the support, thus facilitating the ease by which a use can fold the stairway ladder.

摘要： The adjustable height workhorse is a height adjustable workspace for allowing a worker to easily hang sheet rock on walls at elevated heights. The workhorse provides a platform supported by a frame having a plurality of vertical posts and a plurality of horizontal height adjustment bars. The frame is positioned on a base board. A plurality of wheels is disposed underneath of the base board. The wheels allow the workhorse to be repositioned while the worker is on the platform. The height adjustment bars are mounted on either side of the frame. The bars are positioned at varying heights so that the worker may adjust the height of the platform. The platform is disposed across the frame and is supported by the height adjusting bars. The platform is of suitable size to support a worker and the worker's sheet rock material while providing enough room for the worker to operate.

摘要： A combination hand truck, dolly and step ladder device includes a hand truck frame and a step ladder frame that are pivotally attached to one another and can be fixed at selective angles with respect to each other to form a hand truck, a dolly and a step ladder. In a step ladder configuration, the top step of a step assembly is secured to a cross member of the hand truck frame so as to lock the hand truck frame and the step ladder frame into a substantially fixed relationship to one another. In a dolly configuration, the hand truck frame becomes the handle for the dolly, and is held in place by a support bar that pivotally attaches to the hand truck frame and secures to the step ladder frame.

摘要： A cart and ladder combination includes a plurality of bars such that a first bar and a second bar are defined. A first coupler is adapted for releasably coupling the first and second bars together in a spaced relationship to each other. A second coupler is adapted for releasably coupling the first and second bars together in a spaced relationship to each other. A wheel assembly is removably attached to the first ends of the first and second bars. A cord member is selectively strung between the first and second bars. The second end of the first bar may be selectively attached to the first end of the second bar to form a ladder.

摘要： A wheeled dolly or support for a ladder is made in two pieces, including a base plate that permanently affixes to an outside surface of a rail of a ladder, and a frame that is removably mounted on the base plate. The frame carries wheels that will support the ladder when the ladder is placed on edge and one end of the ladder is lifted. The frame normally is near a base end of the ladder. The frame that holds the wheels can be removed when desired for storage, or for use in a location where the wheels may restrict clearance around the ladder.

摘要： A highly mobile support cart for automotive service personnel presents an elevated support platform over the engine compartment of a vehicle undergoing service. The wheeled frame, ideally supported by a smooth, concrete surface, comprises a rigid, transverse base from which rigid, elongated rails outwardly diverge. The frame mounts an extensible, slightly inclined ladder that supports the work platform. The frame rails and base are equipped with suitable caster wheel assemblies for locomotion. The divergent, reinforced frame design enhances stability and structural integrity. The extensible ladder transported by the frame projects upwardly from the rear. The ladder comprises a lower half pivoted to the frame that telescopingly receives a sliding upper half. Registered locking orifices are pinned by a spring biased clip system to lock the ladder halves against axial displacement. The locking clip comprises a generally C-shaped clasp that is yieldably, spring biased to a locking position. One end of the clasp penetrates aligned locking orifices in the ladder. Ladder orientation is established by a pivotal support brace angularly extending between the frame rails and the ladder. The brace terminates in a lower, transverse foot adapted to be cradled between aligned notches defined in supporting receptacle structure mounted on the frame rails.

摘要： The invention provides a movable ladder support device, and a ladder which includes that support device. The support device includes a rotatable member such as a wheel housed within the U-shaped section of the support device. The support device is attached to the rail of a ladder. The support device enables the ladder to be vertically repositioned against the surface of an inclined wall without the need to first remove the ladder from the surface.

摘要： A foldable portable tree stand is comprised of top and bottom ladder sections hinged to each other, a platform rotatably connected to the top ladder section, and double-angle beams pivotally connected to the platform. When the ladder sections are unfolded, the double-angle beams are retained to the top ladder section to support the platform in a working position. A front guard is slidable within the top ladder section to provide a front railing for the platform. Side guards are slidable within the front guard to provide side railings for the platform. Legs are independently slidable within the bottom ladder section to enable the tree stand to accommodate uneven ground. The top ladder section is swingable to overlie the bottom ladder section. The platform can then rotate to a folded position overlying the top ladder section. The double-angle beams are pivotable to a storage mode between wheels mounted to the bottom ladder section. The double-angle beams are further pivotable to a transport mode whereat they are held to the bottom ladder section and serve as handles for transporting the tree stand over the ground.
