Abstract:
1. A sit down and stand up full step walker comprising: a support frame; roller means mounted on said support frame for contacting a ground surface and rolling the frame; a support lever extending between the support frame and a front body support post and connected rotationally at one end to the post and connected rotationally at the other end to the support frame; a front body support mounted on the front body support post by a swivel joint so that the front body support can be tilted and can be adjustably positioned along the front body support post up or down, said front body support having a front planar surface; a seat having a front end and a back end for supporting a user, said seat mounted on a seat support extension connected to the front body support post and wherein the front of the seat is positioned in a direction facing the front body support and the support frame so that the seat positions the user to face the walker to enable the user's body to push the walker in front of the user and wherein the seat can be adjustably positioned along the seat support extension closer toward or further away from the front body support and wherein the seat is adjustably tilted downward so that the user supported by the seat will be wedged between the seat and front body support with the user's abdominal region in contact with the front body support; a position stabilizing arm positioned at an elevation higher than the support lever and parallel to the support lever, said arm extending between the front body support post and support frame and being rotationally connected at one end to the post and rotationally connected at the other end to the support frame so that the seat and front body support are maintained at a constant angle with respect to a flat ground surface as the position stabilizing arm and support lever move rotationally about the support frame and post; adjustable body weight support spring means rotationally connected on the support frame for applying a full or partial weight-bearing supporting force to the support lever so that the seat, front body support and user are able to move up or down responsive to the variable force supplied by the user as the user walks, stands or sits; a control lever mounted on the adjustable body weight support spring means so that upon movement of the control lever an off center circular disk is turned which releases a gas control pin to limit the movement of a pressurized gas within the adjustable body weight support spring means so that the movement of the seat and front body support can be locked at variable fixed elevations including a sitting height position to allow a user to enter or exit the walker from a sitting position and hold the seat, front body support and user in a continuous sitting position without the application of the user's body weight force or force by another person and so that upon further movement of the control lever the off center circular disk is turned to activate the gas control pin to release the movement of the pressurized gas within the adjustable body weight support spring means so that the seat, front body support and user are released from a sitting position or fixed elevation to a standing or walking position supported by the adjustable full or partial body weight support spring means.
