Patent attributes
Wheelchair hand rim device comprised of a heat conducting tubular hand rim and a continuous circumferential elastomeric interface that has a cross-sectional contour comprised of an outwardly extending horizontal member having a proximal end coupled to an outboard side of a wheel rim transitioning into a downwardly depending member terminating to a distal end coupled to an inboard upper portion of the tubular hand rim such that a majority of the tubular hand rim is exposed and devoid of the elastomeric interface. When braking, a user only uses the heat conducting tubular hand rim. When pushing, the user grips across both the tubular hand rim and the contoured elastomeric interface, which deforms to fit the hand, thereby providing improved comfort, frictional coupling, and impact attenuation.
