The pet bed and step system has multiple components that may be used separately or in combination to provide a raised pet bed having steps or stairs leading to the pet bed. The pet bed and step system includes a foldable base that may be used by itself as a pet bed, or with the rear portion folded up to form a two-step assembly. A step assembly may be mounted on the base and releasably secured thereto by releasable fasteners, such as a zipper, hook-and-loop, or snap fasteners. The step assembly includes at least one intermediate step and a top step, the top step being configured as a luxury pet bed, having a U-shaped bolster around a portion of its periphery and a cushioned pad removably attached to its top surface.

The stair system is made of a deck plate attached to an existing structure (such as a deck) and to the top end of a pair of stringer beams. A base plate is attached to the bottom end of the pair of stringer beams. Next a plurality of steps are attached to the pair of stringer beams, the steps being comprised of a tread assembly, a pair of tread brackets and at least one intermediate support bracket. The steps can be integrally formed or made of modular components which are connected together to form the step. Finally, the decking material is attached to the step.

A prefabricated concrete form with vertical spacers between fill forming cladding with cut-outs in the spacers having horizontal rebar received therethrough and received therein. Stand-offs are provided between the vertical spacers with vertical rebar received on the stand-offs. In one version, the stand-offs are attached to the horizontal rebar. In other versions, the stand-offs are attached to the spacers. A cut-out is formed in one of the claddings to form an auxiliary fill space on the outside of the cladding, which when filled with concrete, upon hardening, forms a ledge for supporting a stair structure.

A prefabricated stair modular assembly mold comprises a base, a step standard module, an upside module of a lower platform, an underside rotating module of a lower platform, an upside module of an upper platform, an underside rotating module of an upper platform, an underside common module, and an underside adjustment modules. Prefabricated stair molds of different dimensions are formed by means of locating holes provided in the assembling modules, and are then fixed by means of sliding holes at two ends. Further disclosed is a mounting method for said assembly mold. Said assembly mold has high positioning accuracy, and small accumulated error, improving the mounting efficiency of the prefabricated staircase mold.

A retractable staircase having a first side stringer and a second substantially parallel side stringer connected to a plurality of steps. The first side stringer is fixedly attached to a wall and the second side stringer is pivotally movable about the first side stringer between an extended position, where the steps lie substantially horizontally between the stringers, and a retracted position where the steps lie substantially vertically between the stringers. The retractable staircase also includes a collapsible handrail and a gate that are interconnected with the side stringers and the pivoting steps so that when one of them is moved, the other two move substantially simultaneously.

A seat for a stair lift includes a horizontal seat, a vertical back rest, and two arm rests. Each arm rest is connected to the seat by a support bracket, and each arm rest is pivotable between folded-down and a folded-up positions. The arm rest is pivotably connected about a pivot axis to the support bracket and to a carrying beam having upper and lower sides. The upper side supports an arm of the sitting person. The arm rest is designed such that lower and upper tangents of the carrying beam extend at the same side of the pivot axis. The lower tangent is at a radial distance from the pivot axis, such that in the folded-up position the carrying beam extends from the vertical plane through the pivot axis in the vertical space behind the vertical plane towards and beyond the back side edge of the seat part.

A pet staircase may be formed by joining modular units to each other in succession and that overlie a household staircase. They are retained in position over the household staircase. Each modular unit has stairs and/or ramps. The treads may be adjusted so that they all are parallel to each other and extend horizontally.

A method of increasing usable space in a parking lot. A support assembly and an access system are erected. A module is placed on the support assembly in one piece or section-by-section. There is an accessible volume of space below the module that is sufficient to allow an automobile to park in a parking space below the module or to allow an automobile to drive in a drive aisle below the module. The module is removably connected to the support assembly. The module may include a frame and a covering coupled to the frame. The support assembly may include portions positioned between adjacent parking spaces of the parking lot. One portion of the support assembly may be positioned on one side of a drive aisle with another portion of the support assembly positioned on the opposite side of the drive aisle.
