Abstract
A bi-axial ball tip for use with a mobility cane. The bi-axial ball tip includes an omni ball, at least two mirrored brackets, and a grip. The mirrored brackets form a chamber to accommodate part of the omni ball, allowing the omni ball to rotate around a horizontal axis inside the chamber. The rotation of the omni ball when the ball engages a ground surface and is provided to aid visually impaired people. The grip connects the mirrored brackets in a manner such that the mirrored brackets and the omni ball, together, rotate around a vertical axis which is orthogonal to the horizontal axis.
Claims8
A mobility cane comprising:
- a mobility cane stick adapted to be held at an inclined angle relative to the ground by a user;
- and
- a bi-axial ball tip engaged with the mobility cane stick, said bi-axial ball tip comprising:
- an omni ball having a ground-contacting exterior surface which is generally spherical in configuration;
- at least two mirrored brackets;
- and
- a grip;
- wherein each of the mirrored brackets has an upper part and a bottom part;
- wherein when the upper parts of the mirrored brackets are matched together, they form a tube;
- wherein a vertical axle is placed in the upper parts of the mirrored brackets within the formed tube;
- wherein the vertical axle is inserted into an aperture defined in a top of a bearing and a bolt is threaded through the aperture defined in the bearing and into a bottom of the vertical axle;
- wherein the bottom parts of the mirrored brackets have arcuate surfaces which form a chamber to accommodate part of the omni ball rotating inside, allowing the omni ball to roll across the ground while rotating around a horizontal axis inside the chamber;
- and
- wherein the grip connects the mirrored brackets in a manner that the mirrored brackets and the omni ball together rotate around a vertical axis which is orthogonal to the horizontal axis;
- and
- wherein the mobility cane is movable in a lateral direction relative to a motion of the user while the omni ball is in contact with the ground.
