Retractable stairs and cord assembly
A ladder assembly is described. The ladder assembly includes a frame, a door, a ladder and a cord manipulation assembly. The frame at least partially surrounds a first opening. The door is movably connected to the frame. The door is configured to cover at least a portion of the first opening of the frame, the door defines a second opening. The ladder is connected to at least one of the frame and the door. The ladder has a first side rail, a second side rail spaced a distance apart laterally from the first side rail, and a plurality of rungs extending between the first and second side rails. The ladder is configured to be at least partially positioned within the first opening of the frame. The cord manipulation assembly is positioned between a pair of adjacently disposed rungs of the ladder. The cord manipulation assembly has a power source connector, a reel adapted to support a cord, a motor operatively connected to the reel and the power source connector, and a remote control transceiver assembly operatively connected to the motor and the power source connector.
FOLDABLE STAIR ASSEMBLY
A foldable stair assembly and emergency escape stairway kit. The foldable stair assembly includes a first tread section hingedly attached on a first end to a first end of a second tread section. Each of the first tread section and second tread section includes two or more treads attached to left and right rails. A mounting bracket is attached to on a distal end of the left and right rails of the second tread section. Flexible straps are attached to distal ends of the left and right rails of the first tread section.
Stairs and Platform System for Mobile Elevated Shelter
A shelter includes a body having a wall. A stairs and platform system is connected adjacent the wall of the shelter. The stairs and platform system includes a platform and a stair assembly. The platform includes: (i) first and second spaced-apart side rails and a platform floor located between the first and second side rails; and (ii) first and second platform handrail assemblies respectively located on opposite first and second lateral sides of the platform. The stair assembly is connected to the platform to provide access to the platform and is movable relative to the platform from a first operative position in which the stair assembly projects outwardly away from the platform to a second stowed position in which the stair assembly is retracted relative to the platform and at least part of the stair assembly is supported adjacent the platform. The first and second platform handrail assemblies are each selectively configurable to be in: (i) an operative position in which the first and second platform handrail assemblies project respectively upwardly from the opposite first and second lateral sides of the platform; and (ii) a stowed position in which the first and second platform handrail assemblies engage both the platform and the stair assembly to capture and retain the stair assembly in its stowed position.
Lateral folding units
A lateral folding step unit and/or desk 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. At least one of the linkages has a receiving surface to serve as a step, a shelf and/or as a work surface.
INSULATION HATCH WITH A SPACER AND ATTIC STAIRS WITH THE INSULATION HATCH
Insulation hatch for attic stairs constructed out of rigid layer (12), protective layer (11) and insulation layer (13) wherein insulation layer (13) is located between rigid layer (12) and protective layer (11) and insulation hatch layers are connected to each other and in protective layer (11) and in insulation layer (13) there is at least one spacer (4) for taking on the load exerted on the insulation hatch, in particular during transport, and the subject-matter of the invention also comprises attic stairs with the said insulation hatch.
