  • Patent number: 6375166
    Abstract: A fenced assembled from a plurality of pickets and at least one insert and at least one rail. The insert is laid across the pickets which are preferably arranged in spaced-parallel fashion. A piercing tool pierces through the insert and an associated picket, causing at least one tab of the insert, formed by the piercing action, to extend into the picket. The channel-shaped rail slides over the insert so that an integrated hook rib shape-fittingly moves into a gap between two integral legs provided near one end of the insert to lock the rail and insert to one another. The rail, in the locked position, substantially completely covers the insert, providing fence having an aesthetically appealing outer appearance.

  • Patent number: 5660378
    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.

  • Patent number: 4182087
    Abstract: A swimming pool of circular or oval shape constructed of interleaved extruded aluminum panels with water containing liner secured thereto wherein hoop stresses in the pool walls from the water pressure are withstood along the panels and the joints therebetween. The pool walls are constructed from a plurality of interleaved extruded aluminum panels which are constructed so that when a pair of adjacent panels are positioned relative to each other in a first predetermined position, the male and female joint portions can be slid, one within the other with sufficient extra space or play to allow easy insertion and assembly. However, when the two adjacent panels are then rotated to a different angle relative to each other, the play or additional space is taken up and the adjacent panels become locked together in an essentially unitary construction.
