20140262575 | MOTION ASSISTANCE SYSTEM FOR WHEELCHAIRS - The presently disclosure describes a motion assistance system for a wheelchair, for example, a powered drive wheel system that can continually drive a wheelchair in a circular or elliptical path. The motion assistance system comprises a mounting mechanism attachable to one or more structural elements of the wheelchair, and a drive linkage pivotable with respect to the mounting mechanism. A drive wheel can be mounted to an end of the drive linkage such that the drive wheel contacts the ground when installed on the wheelchair. The drive wheel comprises a plurality of lateral rollers positioned radially about the circumference of the power drive wheel. The lateral rollers can rotate about an axis tangential to the circumference of the drive wheel in order to facilitate driving the wheelchair in a radial direction. | 09-18-2014 |
20100148466 | Power-Supplemented Manual Height-Adjusting Wheelchair - A wheelchair having a lower frame with drive wheels and forwardly extending arms with casters and an upper frame with a seat and backrest. Linkage assemblies on opposing sides pivotably attach at a first end to the lower frame and at a second end to the upper frame. Power cylinders attached on opposing sides are extendable between the upper frame and the lower frame and are lockable from moving from a selected position. When unlocked, the power cylinders apply a supplemental force in association with a force applied by a user on the drive wheels for moving the upper frame relative to the lower frame guided by the linkage assembly. A method of adjusting the seat height of a wheelchair is disclosed. | 06-17-2010 |
20090320307 | LINEAR MEASUREMENT APPARATUS AND METHOD - A linear measurement device for measuring a wheelchair user for fitting a wheelchair, with a measuring bar having with a scale and a fixed locater attached at a first end. A second locator opposing the first locater moves on the measuring bar to a selected position for determining a distance measurement relative to the fixed locator for fitting the wheelchair user to the wheelchair. A method of measuring for wheelchair fitting with a linear measurement apparatus is disclosed. | 12-31-2009 |
20090314054 | WHEELCHAIR BALANCE TOOL AND METHOD - A balance tool for evaluating weight distribution of a wheelchair positioned on an elongated platform with a support extending from a lower surface and a linear scale, a measuring bar slideably movable relative to the linear scale for making measurements of horizontal distances between a center of mass and the center of the front wheels and the rear wheels, for determining the relative weight carried by the wheels and for adjusting the position of the wheels to have the rear wheels carry a substantial majority of the weight. A method of adjusting the balance of a wheelchair is disclosed. | 12-24-2009 |
