Abstract
The device is a rehabilitation device which aids the user is both sitting and standing.
It consists of a frame constructed of tubular metal with wheels at the front and feet at the back The upper portion of the frame is articulated-it is able to move in an arch motion around the lower half of the frame, thus giving the device two modes:
up and down. The upper portion is affixed to the lower by means of two parallel arms on either side which function as a means to keep the upper frame parallel to the ground throughout the movement. Two pneumatic pistons are affixed at either side, from the lower frame to one of the parallel arms and both pistons are controlled by means of a cable and hand lever. The user is able to rest their weight on the upper portion of the frame, holding onto handles and resting their forearms on the frame. The upper frame moves with them through sitting and standing motions, providing a guide for the movement, support, as well as dampening the downward force when sitting and providing upward force when standing. When the user is standing the device functions as a typical walker, providing support as the user walks.

Description
Specification = This invention relates to a mobility device that uses the dampening and lifting properties of pneumatic pistons to aid the user is both sitting and standing.
= It is common for mobility aids such as walkers and rollators to have wheels and be constructed out of tubular metal frames that provide support for the user when walking upright. However none of these devices address the issue of aiding the user in obtaining standing position or allowing the user to be supported when sitting back down. The mechanical device being employed is pneumatic pistons, such as those use in the hatch of a car to perform a similar operation. Devices which do not support the use through sitting and standing motions leave them at risk of fall during these transition or they must rely on a caregiver to aid in these transfers, possibly putting them at risk of back injury.
= I have found that with the use of simple mechanical devices such as parallel arms on either side of the frame it was possible to have an articulated element of frame that could move in an arch motion around the bottom frame, thus following the users motion when sitting and standing. I also found that by employing pneumatic pistons attached to the bottom frame and back parallel arm, that could be activated or locked by the user's control, their sitting motion could be dampened and their standing motion could be aided.
= In drawings that illustrate embodiments of this invention (in both 'up' and 'down' functions,) Figure 1 is an elevation partly in section. Figure 2 is a side view, Figure 3 is a top view, Figure 4 is a front view. Figure 5 is a diagram of the articulated element with the relative scale of a user. Figure 6 is an image detailing all individual elements of the design.
= The device illustrated in Figure 6 comprises of a lower frame 1 which has front wheels 2. Attached to the frame on either side are two parallel arms 3 which are also affixed to the upper portion of frame 4 that includes hand grips 5, and forearm rests. Two pneumatic pistons 6 are attached to either side of the lower frame and the rear parallel arm on either side. The pistons are both controlled by means of a cables 7 which converge at a covered junction to one cable which releases or contracts the cable by means of a hand lever 8 which is attached to one hand grip of the upper frame.
= In order to operate the device from standing to sitting positions, the user must pull the hand lever and shift their center of gravity backward as one does when sitting down normally. Pulling the hand lever pulls the cable allowing the pistons to engage and allowing the upper frame to move backward in an arch motion around the lower portion of frame. The user moves with this movement and is supported throughout the motion to their seat. When the user is seated on a chair or bed they my release the upper frame and hand lever, which will cause the cables to relax, thus locking the position of the pistons and frame. When the user operates the device from sitting to standing positions the user must lean their center of gravity forward as one does when standing up normally. Once the user has grasped the handle and their upper body is supported by resting their forearms on the upper portion of frame they may pull the hand lever, thus pulling the cable and activating the pistons, which will expand and raise the upper potion of the frame in an arch motion around the lower portion of frame. The user is aided and guided throughout the movement.

Claims (4)
1. A manually operated device which uses stored and released energy in pneumatic pistons by mean of an arch motion between two frames (upper and lower) affixed two each other with parallel arms on either side to aid the user is both sitting and standing.
2. A device as defined in claim 1 which aids the user in sitting by supporting their weight throughout the downward motion and dampening the ascend.
