Abstract
A foldable rolling walker having a high crossbar for easier walking convenience, height adjustable handles centered over offset wheels for greater stability, lockable pivoting front wheels and reversible brakes. The overall design is compact, lightweight and very stable. The walker includes a seat removably mounted between the side frames of the walker by collar clamps secured to the frame of the walker.
Claims10
A rolling walker comprising:
- (a) a horizontal cross-brace;
- (b) side frames pivotally mounted at each end of the horizontal cross-brace, each side frame having a front leg, a rear leg and a horizontal element interconnecting the front and rear legs at the top thereof;
- (c) a wheel mounted adjacent the bottom of each rear leg supporting the rear end of the walker;
- (d) a wheel mounted at the bottom of each front leg for supporting the front end of the walker, said wheel being offset forward of the pivot axis of each side frame;
- (e) a hand support having a free end and a fixed end mounted on and extending upwardly from the horizontal element of each side frame such that a handgrip mounted adjacent the free end of the support is positioned substantially midway between the front and rear wheels for supporting a person so that the person's weight is centered substantially equally between the front and rear wheels;
- (f) said front wheels being normally axially pivotable such that the walker may be pushed in different directions;
- and
- (g) a locking lever operatively associated with each front wheel which is movable between a locked position which maintains each front wheel in an aligned front to rear non-pivoting position and an unlocked position wherein each wheel is freely pivotable about its mounting axis.

- (e) a hand support having a free end and a fixed end mounted on and extending upwardly from the horizontal element of said side frame, such that a handgrip mounted adjacent to the free end of the support is positioned substantially midway between the front and rear wheels for supporting a person so that the person's weight is centered substantially equally between the first and rear wheels;
- (f) hand brake lever means pivotally attached to the hand supports;
- (g) at least one wheel engaging element mounted on the side frame in braking relationship to a rear wheel;
- (h) means interconnecting the hand brake lever means and the wheel engaging element whereby operation of the hand brake lever means produces braking of said wheel;
- and
- (i) means of changing the orientation of the wheel engaging means to convert the walker between a brake normally ON mode and brake normally OFF mode of operation.
