Each modular hinge has a bearing housing with bearing recesses, two bearing bodies, each bearing body being received in a respective recess. Each bearing body is interengagable with a respective front or rear leg, and, a transverse assembly bar is connected to the hinge mounting and secures the hinges in spaced apart side by side relation. Also disclosed is a brake locking system for an in-line two part brake handle, and a multi-use seat for a walker.
Claims16
A walking aid for physically challenged persons having two front and back leg assemblies, each leg assembly having a front leg extending forwardly and downwardly and a rear leg extending rearwardly and downwardly and wheel means at lower ends of the legs and comprising;
- hinge means at upper ends of each of said leg assemblies for swinging thereof, each hinge means having;
- bearing housing means for respective said hinge means each bearing housing means defining respective front and rear semi-circular bearing recesses, spaced apart from one another and defining separate axes of rotation, and pairs of respective front and rear bearing body means, each said bearing body means being received in a respective said bearing recess;
- connection means on each said bearing body means, interengagable with respective said front and rear legs;
- a pair of upwardly extending steering arm means, connected with respective front legs, and,
- transverse assembly bar means, defining two ends, a said end being connected to a respective one of said hinge means, thereby mounting and securing said hinge means in spaced apart side by side relation.
A walking aid having a braking means and comprising;
- walking handles of two part in line construction, said handles in turn comprising;
- a first handle part being rigid;
- a second handle part of each handle being an endwise in line extension of said first handle part and being moveable relative to said first handle part to apply said braking means, and,
- brake locking means on said first handle part of at least one of said walking handles, said brake locking means being moveable to lock said moveable second handle part of said at least one walking handle for locking said braking means when they are applied, and being manually releasable.
A walking aid for physically challenged persons comprising;
- two front and back leg assemblies, each leg assembly having a front leg extending forwardly and a rear leg extending rearwardly and wheel means at lower ends of the legs;
- front and rear hinge means at upper ends of said leg assemblies;
- bearing housing means in each hinge means defining two generally semi-circular bearing recesses, spaced apart from one another and defining separate axes of rotation;
- releasable connection means on each said hinge means, interengagable with respective said front and rear legs;
- a pair of upwardly extending steering arm means, releasably connected to said front hinge means, and,
- transverse bar means, defining two ends, respective said ends being releasably connected to a respective said hinge means, thereby mounting and securing said hinge means in spaced apart side by side relation.
