Step canes for assisting a person in walking up and down stairs comprising an elongated and rigid cane for supporting the attitude of a user, the cane having a tip end adapted to contact a walking surface, a handle end adapted to provide a user a firm grip, and a downwardly extending intermediate portion therebetween; a platform rotatably coupled to the intermediate portion of the cane, the platform operable in an extended position to allow a user to walk up and down stairs and in a retracted position to allow a user to walk on a generally level surface; and a controller mechanism coupled between the cane and platform to place the platform in either the extended or retracted position.

A new and improved step cane for assisting a person in walking up and down stairs comprising, in combination: a rigid and hollow cane for supporting the attitude of a user, the cane having a tip end, a handle end, and a downwardly extending intermediate portion therebetween, the tip end to contact a walking surface, the handle end to provide a user a firm grip, and the intermediate portion having a releasing aperture, a lifting aperture, a coupling aperture, and an extending aperture disposed thereon, the releasing aperture disposed near the handle end, the lifting aperture disposed below the releasing aperture, the coupling aperture disposed below the lifting aperture and further including a clip spring coupled thereto, and the extending aperture disposed below the coupling aperture; a platform rotatably coupled to the cane between the tip end and the extending aperture, the platform operable in an extended position to allow a user to walk up and down stairs and in a retracted position to allow a user to walk on a generally level surface, the platform further comprising: a rigid and essentially rectangular plate having an upper surface and a lower surface, the plate oriented horizontally when in the extended position and oriented vertically when in the retracted position; a first support leg and a second support leg attached to the lower surface of the plate and extending downward to contact the walking surface when the plate is in the extended position, with the tip end of the cane and the two support legs defining a tripod for supporting the plate; a first hinge and a second hinge, the first hinge connected between the first support leg and tip end of the cane, the second hinge connected between the second support leg and tip end of the cane, the hinges operable in unison to position the plate in either the extended or retracted position; and a mounting bracket coupled to the plate, the bracket having a hole disposed thereon to receive a cable; a control mechanism coupled between the cane and platform to place the platform in either the extended or retracted position, the control mechanism further comprising: an elongated lift lever having a first end, second end, and intermediate portion therebetween, the first end rotatably coupled to the cane above the lifting aperture, the second end having a handle formed thereon, and the intermediate portion having a hole disposed thereon adapted to receive a cable; a lifting cable placed within the intermediate portion of the cane and having one end disposed through the extending aperture and coupled to the hole of the mounting bracket and the other end disposed through the lifting aperture and coupled to the hole of the lift lever, whereby rotating the handle of the lift lever upwards moves the platform to the retracted position and rotating the handle downwards moves the platform to the extended position; an elongated release lever having a first end, a second end, and intermediate portion therebetween, the first end having a hole formed thereon and disposed within the cane, the intermediate portion extending from the first end through the releasing aperture to the second end, the second end having a handle formed thereon; a release detent having a first end, a second end, and an intermediate portion therebetween, the first end having a hole formed thereon and disposed within the cane, the intermediate portion coupled to the lifting cable and extending from the first end through the coupling aperture to the second end, the second end having a hook formed thereon; and a releasing cable placed within the intermediate portion of the cane and having one end coupled to the hole of the release detent and the other end coupled to the hole of the release lever, whereby when the platform is in the extended position, rotating the handle of the release lever downward engages the hook with the clip spring to lock platform in place, and rotating the handle downwards disengages the hook with the clip spring to unlock the platform, thus enabling the platform to be placed in the retracted position with the lift lever.
