  • 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.
