Abstract: A rail mounting system for mounting accessory items to truck bed sidewall includes a rail having a horizontal portion and a vertical portion adapted to respectively engage horizontal and vertical sidewalls of a truck bed. The rail further includes an angled extension extending nonorthogonally from the vertical portion and defining at least one opening therethrough. The rail further includes a bearing surface extending from the angled extension at a substantially orthogonal angle. A clamp is provided to hold the rail in position and includes on one end a clamping surface and on the other end a bearing surface engageable with the rail bearing surface. A fastener passes through the opening in the rail and attaches to the clamp. Upon tightening the fastener, the clamp slides along the rail bearing surface towards the angled extension. The nonorthogonal angle of the angled extension allows the clamp to exert either a vertical force, a horizontal force, or both on the truck bed sidewall.

Abstract: An adjustable clamp with an attached retaining ring is disclosed. The clamp is formed from two extrusions, an L-shpaed extrusion which includes a groove for receiving the retaining ring along with one portion of a hinge structure, and a U-shaped extrusion which includes a mating portion of a hinge structure. The retaining ring is seated in the groove or channel of the L-shaped extrusion and the edges or lips of the channel crimped closed to capture the retaining ring. The two extrusions are hingedly joined and then a bolt passed through one and into the other to form the clamp.

Abstract: A device for mounting a downrigger to a sidewall portion of a boat includes a base having a generally flat planar surface for receiving and supporting the downrigger and a clamping arrangement including a pair of spaced apart C-clamps joined by a transverse tightening member which C-clamps are removably fastenable to a sidewall portion of a boat for fastening the base to the boat. A preferably adjustable structure couples the base and clamping arrangement or base support together at selected relative angular orientations thereby allowing mounting on virtually any current open side wall style boat while also allowing the downrigger to be optimally inclined to the water line as selected by the user.

Abstract: An adjustable clamp is formed of two extrusions pivotally joined together by retaining structures consisting of a web and bead extruded as part of one of the extrusions and a channel extruded as part of the other extrusion and having sufficient cross-sectional size to receive the bead longitudinally. Edge portions of the channel define a gap wider than the web but narrower than the bead to allow limited pivotal movement of one extrusion relative to the other about an axis in the channel and to prevent the bead from slipping transversely out of the channel. One extrusion has a body portion with an arm extending from the body portion and a pressure pad on the arm. The other extrusion has a generally U-shaped configuration consisting of a bight and two sides, one of which has an edge with an extruded pressure pad thereon facing the pressure pad on the arm. The other side, which is adjacent the pivot axis defined by the bead and the channel, is juxtaposed with respect to the body portion of the othe extrusion.
