Abstract:
1. A support apparatus for supporting a tool on an object, the tool configured to provide a pushing force on the support apparatus when the tool is activated, said support apparatus comprising a frame and a retainer on the frame for retaining the support apparatus on the object, the tool being attached to the support apparatus and the support apparatus configured to be supported against the object without any clamping action when the tool is not activated, wherein the retainer comprises an upper and a lower support claw, the upper support claw defining a configuration with two rails spaced apart from each other, the rails of the upper support claw defining a first contact region spaced apart from a second contact region, the first contact region including two contacting edges and the second contact region including two contacting edges, the lower support claw defining a configuration with two rails spaced apart from each other, the rails of the lower support claw defining a third contact region spaced apart from a fourth contact region, the third contact region including two contacting edges and the fourth contact region including two contacting edges, the rails of the upper support claw defining a mouth that opens toward a mouth defined by the rails of the lower support claw, at least one of the first and second contact regions of the upper support claw configured to contact the object and at least one of the third and fourth contact regions of the lower support claw configured to contact the object, the first and second contact regions of the upper support claw and the third and fourth contact regions of the lower support claw being non-rotationally disposed with respect to the frame, wherein the claws are operable at a plurality of orientations with respect to the object and a curved bearing region for the tool, the bearing region being adjacent and and parallel to the upper support claw, the frame including the upper and the lower support claws forming a C-shape, wherein the upper and lower support claws are configured to cant with respect to a portion of the object located between the two support claws during the activation of the tool such that a clamping effect is caused by diametrically opposed contact regions of the upper and lower support claws on the object when the tool is activated.
