摘要： A collapsible stair with foldable ramp can include a first step, and a second step nestable within the first step such that when the collapsible stair is in a closed position the second step is aligned with the first step and when the collapsible stair is in an open position a lateral offset between the second step and the first step is increased. A third step can be nestable within the first step such that when the collapsible stair is in a closed position the third step is aligned with the second step and is in an open position a lateral offset between the third step and the second step is increased. A ramp can be rotatably coupled to the first step to rotate from a stair position to a ramp position, wherein the ramp position comprises the second step and the third step being covered by the ramp.

摘要： A height adjustable loading ramp installed at a tail of a car, for loading or unloading goods, includes: a slope plane and a supporter. The two ends of the slope plane are respectively supported on the ground and the supporter. The supporter includes: two supporting legs adjustable in length, a beam horizontally provided between lower portions of the two supporting legs, wheels for making the loading ramp move conveniently, and a scissor jack for adjusting the height. The scissor jack includes: four scissor jack arms equal in length, and an adjusting-locking device for adjusting and locking the height of the height adjustable loading ramp. In addition, the supporting leg comprises an auxiliary fixing unit for fixing the relative position between the upper and the lower supporting legs and providing an extra security protection, in such a manner that the height of the height adjustable loading ramp is locked.

摘要： An operable ramp is moveable between a raised (step) position and a lowered (ramp) position. The operable ramp includes a first panel rotatably coupled about a first axis, the first axis that moves back and forth as the operable ramp reciprocates between the raised and lowered positions. A second panel is rotatably coupled to the first panel and extends downward from the first panel in the raised position. The second panel also rotates about a fixed second axis. The first and second panels cooperate to provide an inclined surface when the operable ramp is in the lowered position. A linkage selectively rotates the first panel about the first axis. The operable ramp further includes a third panel rotatable about a fixed third axis. The third provides a surface between the first panel and a fixed panel when the operable ramp is in the raised position.

摘要： A portable modular pedestrian ramp comprises a plurality of modular ramp units. Each of the modular ramp units comprises a pair of side edge plates each having inwardly facing sides to which opposite ends of decking are attached. The side edge plates of at least some of the modular ramp units have opposite ends thereof that are releasably connectable to one another by self-locking connectors to provide different ramp lengths without the need for any tools or fasteners to join the modular ramp units together or disassemble the modular ramp units for transportation and storage.

摘要： An operable ramp is moveable between a stowed position and a deployed position. The operable ramp includes a support element and an inner ramp rotatable at a first end about a first axis. The operable ramp further includes an outer ramp rotatably coupled to a second end of the inner ramp about a second axis. The outer ramp has a first cam follower that engages a slot formed in the support element. A drive assembly selectively rotates the inner ramp relative to the outer ramp, such that rotation of the inner ramp in a first direction moves the second axis from a raised position to a lowered position. The operable ramp forms a step in the stowed position, and the outer ramp and the inner ramp form an inclined transition between a first surface and a second surface when the operable ramp is in the deployed position.

摘要： An adjustable, modular handicap-access-ramp system enables transport of wheelchairs and temporarily or permanently physically handicapped individuals and no-step access thereof into and out of a structure. The system comprises a plurality of core modules and at least one additional module adapted to be combined with each other and the core modules to configure a customized ramp. At least one combined locating and support pin is adapted to connect to each other those of the core and additional modules disposed adjacent to each other. At least one substantially infinitely adjustable column assembly allows movement of predetermined core and additional modules up or down and to a desired angle. At least one connector allows attachment to each other of adjacent core and additional modules that require a change in grade with respect to each other.

摘要： A ramp is assembled from first and second boards such that the first and second boards are foldable relative to one another. Rail assemblies comprising first and second channels are fastened along opposing sides of the boards. First and second hinge members, fastened to the sides of the first and second channels, pivotally couple the channels. Two central hinge members are mounted on the boards respectively to pivotally couple the boards at a central location between the opposing sides of the boards. An auxiliary hinge member is supported on the bottom of the first channels to provided added support to the pivotal coupling between the first and second channels. The auxiliary hinge member and the central hinge members are interchangeable with one another.

摘要： Methods and systems for stairways or other walkways supported at only one end provide a plurality of stair treads are attached to a support beam, a pair of mounting brackets disposed at either side of a support beam bottom end rotatably connected to the support beam by a pivot bolt, the mounting brackets connected to a base, the base connected to a load bearing structure. A support bolt is disposed through the mounting brackets and below a bottom surface of the support beam. Locking means pivotally connected to the support beam engage a base mounting plate and restrain the stairway from at least one of pivoting upward about the pivot bolt or pivoting downward about the pivot bolt. Operative loads transfer from the support beam into the support brackets through the pivot bolt and support bolt and through the base into the load bearing structure.
