ABSTRACT:
A wrist support for use with electronic computing devices includes a plurality of rollers rotatably attached to roller supports, which are attached to a base. The rollers are positioned arcuately within the roller supports having a center roller positioned at a slightly higher elevation as compared to adjacent rollers. The rollers have protuberances at each end for engagement with holes in the roller supports for enabling the rollers to rotate about an axis. The rollers may also be inclined at a first angle extending from an inner roller support toward an end roller support and at a second angle extending from the inner roller support toward the other end roller support. Pads are attached to the base for enabling the base to flex and provide a cushion between the base and a support surface. Spacers are attached to the base so that the rollers contact the spacers instead of contacting the base. The wrist support may additionally include a pivot attached to the base and to a support for enabling the base and rollers to pivot about the support for use with a computer mouse. Alternatively, the wrist support may include an expandable member attached to a two piece base for enabling a person to adjust the space between adjacent sets of rollers.
