    Abstract: The arched multi-segmented ramp assembly of the present invention has the advantageous qualities of being portable, lightweight, easily deployable and storable. Identical step links have keystone-shaped sides that abut adjacent members and are joined one to the other by knuckle-like hinges, both of which structural features impart to the unrolled assembly a gently arcuate contour, thereby enhancing the ramp's strength to weight characteristics compared to ramps of the prior art. The hinge connections further permit the ramp to be rolled up for easy transport and storage. Because of its modular design, the arched ramp may be assembled using varying numbers of component step-links, thus providing a user with the flexibility to form a ramp assembly with lengths suitable for different particular applications.

  • Patent number: 5634440
    Abstract: A convertible step and ramp combination having a frame (15, 16) with removable steps (19, 23) which may be converted into a ramp (19, 23). The three steps have attached hangers (20) which rest on rods (10, 12) extending between frame while in step mode. Conversion to ramp mode is done by loosening wing nuts (18) and removing three steps, then placing steps at an angle by repositioning three hangers on wooden dowel (14) and rod (11). The step and ramp combination is independent of any other supporting structure and may be used for ascension and descent from a variety of higher surfaces. The steps and convertible ramp are covered with a non-slippage material for traction. The ability to chose between the step or ramp feature allows pets of various physical conditions to safely ascend and descend from higher surfaces.
