Abstract
The Platform-Lift Walker is a walker featuring a vertical driving platform that can lift objects from the ground while the user is standing. Similarly, the Platform-Lift Walker can lower objects to the ground while the user is standing. The Platform-Lift Walker offers users with balance or bending mobility issues an alternative to commercially available picker or grabber devices that are often difficult to use or unable to lift heavier objects. The Platform-Lift Walker includes a walker, a lifting mechanism, and a platform.
Claims19
A lifting aide device that allows the lifting of objects to and from the ground, the lifting aide device comprising:
- (a) a walker, the walker comprising:
- (i) a frame;
- (ii) a first handle and a second handle;
- (iii) two or more of wheels;
- (iv) two or more wheel locking systems, each wheel locking system comprising:
- (1) a lever;
- (2) a cable;
- (3) a brake;
- (v) where the two or more wheels are operatively connected to the frame,
- (vi) where the first handle and the second handle are attached to the frame,
- (vii) where the lever of each wheel locking system is attached to one of the handles,
- (viii) where the brake of each wheel locking system is operatively connected to one of the wheels;
- (b) a platform;
- (c) a lifting mechanism, the lifting mechanism comprising:
- (i) one or more means for driving the platform along vertically;
- (ii) a prime mover;
- (iii) an energy storage device;
- (iv) a controller;
- (v) a plurality of sensors;
- (vi) where the prime mover is operatively connected to at least one of the means for driving the platform along vertically and to the energy storage device,
- (vii) where the controller is operatively connected to the prime mover, the energy storage device, and the plurality of sensors,
- (d) where one or more sensors are attached to each of the one or more means for driving the platform along vertically,
- (e) where the lifting mechanism is attached to the frame of the walker,
- (f) where the platform is rotatably attached to the one or more means for driving the platform along vertically.
