Compact cantilevered ambulatory assistive device

摘要

The Compact Cantilevered Ambulatory Assistive Device is intended to give physical support to persons having diminished abilities to walk, stand from a sitting position or to be seated from a standing position or maintain their balance. The design of the Compact Cantilevered Ambulatory Assistive Device supplies an upward force to the user through the Elongated Cantilevered Handles when transitioning from a sitting position to standing and provides stable support to the user when going from standing to a sitting position. The device maintains a stable support for the user by keeping the center of gravity of the device below the center of mass of the user, while walking, standing or transitioning from standing to sitting or from sitting to standing through the incorporation of cantilevered multi-wheeled bogie assemblies with the of the device's vertical support frames, the bogie assembly wheels being of such small diameters as to move without impediment under obstructions such as furniture, fixtures or seating.

主权项

1. An assistive device, utilized by a user having diminished abilities to walk, stand, maintain balance while standing or during the act of sitting or standing, comprising:
a) a right hand and a left hand structure; b) where in the left and right hand structure held in union with a bearing surface so as to provide rotational movement around the common longitudinal axis of the right hand and left hand structures; c) the right hand and left hand structures having horizontal and vertical struts as to provide an elevated platform with restrictive side access, partial front access and open rear access; d) a mechanism coincident to the rear face of the right hand and left hand structures being movable in the vertical plane further being retained in its vertical path by guides and concurrently held in parallel alignment with the apex of the right hand and left hand structures; e) said mechanism movable in the vertical plane having a means of restricting movement of the mechanism in an upward or downward vertical direction; f) said mechanism movable in the vertical plane having a means of supplying force in the upward direction between said mechanism and the right hand and left hand structures; g) the forward bottom face of each right hand and left hand structure having affixed a swivel wheel, the vertical axis of the swivel wheel being offset and perpendicular from the axis of rotation of the swivel wheel; h) the rear bottom face of the right hand and left hand structure being joined independently with a cantilevered bogie structure comprised of multiple wheels mounted in-line with the axis of rotation being perpendicular to the mechanism; i) the rear most bogie wheel of the device having a wheel center of rotation located vertical and beyond the rear most edge of the mechanism movable in the vertical plane of both the right hand and left hand structures; j) the bogie wheels having such diameters as to allow the bogie structure to move unobstructed under objects of limited clearance between the object's base and the rolling surface; k) and the bogie structure further having a means for limiting wheel movement to stop or redirect the assistive device.
