Patent ID: 8534234

Claim:
A reversible pet spiral staircase, comprising: a. a self-supporting reversible bottom tread storage platform member having an upper surface and a lower surface, wherein said self-supporting reversible bottom tread storage platform member is non-fixedly attached to a structure and capable of independent support; b. a center leg support member, which may be vertically reconfigured by assembling said center leg support member from a plurality of center leg support member segments, thereby allowing the height of said reversible pet spiral staircase from the ground to the top of said reversible pet spiral staircase to be adjustable; c. a plurality of tread platform members, elevated above said self-supporting reversible bottom storage platform member, which are positioned in an upwardly helical path relative to said center leg support member; d. a plurality of outer leg support members, which provide support to said tread platform members; e. a helical skirt board railing member that supports said tread platform members and traverses the perimeter of said reversible pet spiral staircase; f. a first recess member located on said upper surface of said self-supporting reversible bottom tread storage platform member, and a second recess member located on said lower surface of said self-supporting reversible bottom tread storage platform member directly underneath said first recess member, such that turning over said self-supporting reversible bottom tread storage platform member allows said reversible pet spiral staircase to be assembled in either a left-hand spiral configuration or a right-hand spiral configuration; and g. a first traction member removably inserted into the upward facing first or second recess member of the self-supporting reversible bottom tread storage platform defining the first step of the reversible pet spiral staircase.
