ABSTRACT:
A portable folding grab bar device for aiding a person to stand from a seated position having four primary components, a base, a support column which pivots with respect to the base, a pivot mechanism, and a handle which the user grabs to rise from a seated position. The support column pivots with respect to the base to enhance portability. The base is designed for the user to stand upon while the handle is grasped, thus the users own body weight is used to stabilize the device in use. The device is constructed from lightweight materials to further enhance portability. The pivot mechanism is designed to prevent over rotation of the support column and to remain rigid and stable after extended use. The pivot mechanism includes a sliding locking block and is inexpensive to manufacture. The handle has a variable extension member so the height of the handle from the base may be varied to suit the users height or reach.
