A folding handle device is disclosed, mountable to an article to be carried, having a rotatable U-shaped handle with leg members adaptable to pivotally receive a mounting shaft, each leg member having a base having planar surfaces in which the handle be held upright or folded. The device further includes two mounting shafts rotatably mounted to the handle through apertures in a planar mounting surface and are retained in place by a nut. A spring between the nut and the bottom side of the mounting surface bias the mounting shaft away from the bottom side of the planar mounting surface. The handle is adapted to facilitate axial movement of the shafts relative to and perpendicular to the planar mounting surface as the handle is rotated between the upright and folded positions, wherein when the handle is either in the upright position or folded position, the spring is under a compressive load, and during the transition from the upright to folded positions and the transition from folded to upright positions, the spring is under a greater compressive load than that when the handle is in the upright position or folded position.

[ We claim:] [1.] A folding handle device, mountable to an article to be carried, the article having a generally planar mounting surface having top and bottom sides, the folding handle comprising:(a) a rotatable U-shaped handle having two leg members and a spanning member connecting the leg members, each leg member having a means adaptable to pivotally receive a mounting shaft, each leg member having a base having planar surfaces that enable the base to sit flush against the planar mounting surface in a plurality of positions, including a position in which the handle is upright and including a position in which the handle is folded parallel to the mounting surface;(b) two mounting shafts, each having a pivot end and a retaining end, each mounting shaft rotatably mounted to a base of the handle at the pivot end of the mounting shaft;(c) the retaining ends of the mounting shafts mounted through apertures in the planar mounting surface such that the handle is on the top side of the mounting surface and the retaining ends of the mounting shafts protrude through the bottom side of the mounting surface and retained in place by a retaining means to captivate the handle to the planar mounting surface;(d) biasing means between the retaining ends of the mounting shafts and the bottom side of the mounting surface, to bias the retaining ends of the mounting shaft away from the bottom side of the planar mounting surface; and(e) the handle adapted to facilitate axial movement of the shafts relative to and perpendicular to the planar mounting surface as the handle is rotated between the upright and folded positions, wherein when the handle is either in the upright position or folded position, the biasing means is under a compressive load, and during the transition from the upright to folded positions and the transition from folded to upright positions, the biasing means is under a greater compressive load than that when the handle is in the upright position or folded position.
