Abstract:

A longitudinal receptor construction for insertion into a channel or opening and for holding a desired element is provided. The receptor has an inverted L-shape cross section in which a horizontal leg is advantageously suited for retrofit usage in an existing groove or channel opening and has locking features which afford substantially improved capability for holding the receptor and the element inserted into the receptor. The groove into which the receptor is positioned may be the groove contiguous to a swimming pool coping and may be the same groove devised for and used to hold another element such as the peripheral bead of a swimming pool liner. Sufficient gripping force by the horizontal receptor leg in the locking groove or channel is provided by the receptor leg configuration which prevents dislodging of the receptor leg by forces pulling on the receptor or other member which may be present in the opening. Advantageously the receptor may be used on an existing pool coping which has a channel or groove into which the peripheral bead of a vinyl liner which covers the swimming pool bottom is positioned. The securing leg of the receptor of the invention is of slender construction and contoured that it can be accommodated, together with the bead of the swimming pool liner, within a conventional pre-existing channel or groove such as that in the upper inner wall or coping of a swimming pool which houses the bead of a pool liner.
