Swimming pool

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. This is accomplished by providing a cam surface on one of the joint portions and a cam follower on the other of the joint portions so that, upon rotation of the panels relative to each other, the cam follower will ride up on the cam and take up any of the slack or tolerance in the joints. The panels are locked in the non-slack position after assembly. The joints are preferably positioned so that the joint portions other than the cam and cam follower portion, are substantially symmetrical on each side of each panel axis.
