Abstract: A one-piece molded retainer clip is mountable onto any desired surface. The retainer clip includes a back wall for mounting to the surface and a raised front wall having a mounting button access slot formed therein. A clip finger having a resilient end portion extends from the back wall into the access slot to bear against the mounting button when inserted therein. The access slot has a pair of guide walls and overlying wall portions to engage and retain a flange of the mounting button. The clip finger preferably is biased against the mounting button and can include a projection for engagement with the mounting button or an electrical ground or a resilient biasing member.

Abstract: A rail clamp is provided comprising a pair of substantially identical opposing side pieces or members in which the side members have a means for slidably interlocking with one another at one end of the side members, a semicircular portion located in in approximately the middle of each side member, a hole for fastening the two side members together after they have interlocked around a rail, and a hole for mounting auxiliary equipment to the rail clamp. The interlocking end comprises a hooking end and a receiving end such that the hooking end of the first side member can slidably interlock with the receiving end of the opposing side member. The hooking end has a hooking lip which forms a hooking channel and the receiving end has a receiving lip which forms a receiving channel such that the hooking lip slides into the receiving channel and the receiving lip slides into the hooking channel when the two opposing side members are brought into a face-to-face relationship.

Abstract: A boats hardware system--especially, although not exclusively designed for pleasure boating--involves massive clamping parts fashioned from a plastic, which is light enough to float. The parts are shaped and proportioned to fit over and be clamped to a rail of a boat. Clamping is preferably accomplished by large head nuts which may be fully tightened responsive to finger pressure. A rubber or other friction forming plug or screw head may be used to increase the friction or immobilize the clamp on the boat rail so that it will not turn about the rail. For convenience of description the term "anti-torque" is used hereinafter to mean this non-turning immobilization. The various parts may be used together in different combinations to make a system which easily fits into place, even when bulky items are installed by one person. An important advantage of the invention is its ability to be mounted on a boat without requiring either an undue amount of time or any special tools.
