A portable cane seat, comprised of:
- a shaft, said shaft having a top end and a bottom end and comprising a hollow cylinder having an elongated longitudinal axis and being made from a lightweight and stiff material, said shaft is approximately one inch in diameter and three feet in length along its elongated longitudinal axis, and further wherein, said shaft is divided into two equal sections at manufacture to allow a telescopic mid-section assembly to be inserted into a hollow cavity on eahc adjoining end of said sections and a simple spring loaded mechanism allowing one to unlock the telescopic mid-section assembly to allow the user to extend and retract the length of said cane seat as desired;
- a pivoting handle said pivoting handle being located on said top end of said shaft via a hinge;
- a retractable seat assembly, said retractable seat assembly for providing a surface for sitting and normally stowed beneath said pivoting handle within a hollow cavity in said top end of said shaft, wherein said retractable seat assembly comprises an upper shaft, said upper shaft constructed from a strong, lightweight metal and having an upper end, a lower end, an elongated longitudinal axis, and a generally cylindrical shape, and wherein said upper shaft is fluted on two sides so that a spline section with a linearly elongated rectangular cross section is formed along the elongated longitudinal axis of said upper shaft, wherein said retractable seat assembly further comprises a plurality of four articulating seat rods, said plurality of four articulating seat rods extending radially from said spline and pivotally connected at one end to said spline via a flared pin interference fitted in an aperture formed near the top of said spline, wherein said retractable seat assembly further comprises a plurality of two articulating seat rod cross members, wherein each of said articulating seat rod cross members link together a pair of said articulating seat rods via a flared pin interference fitted in an aperture in said seat rod and a retaining clip, wherein said retractable seat assembly further comprises a fabric seat cover, said fabric seat cover being fastened around one of said seat rod cross members by sewing or stapling on one edge of said seat cover and sewn into an opposing edge of said seat cover are small hooks of sufficient radius to grab and hold said opposing seat rod cross member thereby suspending said seat cover between said seat rod cross members, wherein two of the plurality of four seat rods are attached on one side of said upper shaft and the remaining two of the plurality of four seat rods are located on an opposite side of said upper shaft;
- a means for deploying and retracting said retractable seat assembly from within said hollow cavity in said top end of said shaft;
- a base assembly, said base assembly located on said bottom end of said shaft for supporting said cane seat in a vertical orientation on a horizontal surface;
- and
- a means for deploying and retracting said base assembly from within a hollow cavity at the bottom end of said shaft.
