A sit down and stand up walker for assisting a user during walking and when not walking in a standing, partially standing or
sitting positions with partial or full
weight bearing support and with means to change from standing, partially standing to
sitting positions with partial
weight bearing support to a fixed elevation with full
weight bearing support in any varied or
repeated sequence. The partial or full weight bearing means supports a seat
assembly which includes a seat and front body support with adjustable positioning to provide pelvic stability. The angle of the seat
assembly relative to a flat ground surface is maintained at any elevation of the seat
assembly between a standing and sitting position. The weight bearing means is responsive to the variable force supplied by the user as the user walks, stands or sits allowing the seat assembly to move up or down. The weight bearing means in a preferred embodiment is an enclosed
gas spring cylinder with
piston rod that can be locked at differing elevations or released to respond to a user's
body force as the user walks, stands or sits. The walker is intended to be moved without the user's hands holding onto the frame thereby promoting a
normal gait and posture. The walker enables the user to expend less energy as the body's center of gravity with partial or full weight bearing support rises and falls with each stride. The walker facilitates transfers from a sitting to
standing positions and vice versa by the user independently without the intervention of caregivers.
