Abstract: Interlocking clips are provided to assemble structures without the need for conventional fasteners. Structures such as fences, which may be assembled in situ, include the cooperating clips designed to provide a controlled amount of “play” between the pickets and rails of the fence to enable adjustment when racking the fences to accommodate sloping terrain. The clips are provided to interlock rails to cross members. The clips are preferably formed of a single sheet of a springy metallic material. The clips may be advantageously used to couple other types of apparatus.

Abstract: A method of adjusting an adjustable self closing hinge and the hinge which comprises providing an adjustable, self closing hinge. The hinge includes a tube with a hollow interior portion of circular cross section, a first end portion and a second end portion. A spring is disposed in the tube along its axis and has a spring end extending toward the first end portion and a second secured spring end extending toward the second end portion. A depression is provided at the first end portion of the tube extending into the hollow portion and a rotatable member is disposed within the hollow portion at the first end portion thereof and rotatable therein for adjusting the torque of the spring. The rotatable member is secured to the first spring end and has a flat wall portion at the end portion of the rotatable member opposing the spring and parallel to the axis, the wall and the rotatable member together forming a seat in the rotatable member.

Abstract: A method of making an assemblable fence and the fence which includes a plurality of spaced apart pickets, each picket having an aperture therein facing in the same direction, an insert having an edge with a single or plurality of spaced apart fingers disposed along the edge, the spacing between the fingers being the same as the spacing between the center portions of the pickets and a substantially U-shaped rail having an intermediate portion and a pair of spaced apart portions extending from the intermediate portion. The insert is placed between the rail and the pickets so that the fingers are aligned with the apertures and above the apertures in the pickets. The rail and fingers are then moved toward the apertures until the fingers enter and are locked in the apertures. In one embodiment, the step of moving the rail and the fingers further includes continuing to move the rail and the fingers in the same direction after entry of the fingers into the apertures to provide the locking.
