Abstract: A lift assembly is provided. In one embodiment, the lift assembly may be used to raise and lower a bed, such as in a recreational vehicle. The lift may include a platform assembly which is movable between upper and lower positions. The lower position may be located in a lower horizontal plane than the upper position. The lift assembly may further include at least one movable member connected to the platform assembly and which may be activated to perform functions selected from the group consisting of raising the platform assembly, lowering the platform assembly, and combinations thereof. The lift assembly may also include means for positioning the platform assembly in the lower horizontal plane. In some embodiments, the means may be a cradle, while in other embodiments, the means may be a latch. The assembly may include a plurality of movable members which are activated by an electric motor.

Abstract: A non-slip surface is provided comprising a surface having at least one arcuate lug, said arcuate lug comprising a raised center portion and raised and twisted side portions for preventing slippage. Additionally, a process is provided comprising the steps of cutting an arc into a surface, raising and twisting said arc in relation to said surface by bending said surface along a secant perpendicular to a line connecting the midpoint of said arc and the secant, creating at least one arcuate lug in said surface.
