Abstract:
1. In a fluid coupler for coupling a male end into a female end, said coupler comprising a main housing having a first male end for connecting to a female end of a mating element, and a second female end having a main wall consisting of an inner circular wall portion interiorly of which is defined a hollow interior for receiving therein a threaded mating male end having a series of sloping threads, and a sealing washer operatively associated with said second female end for providing a fluid seal, the improvement comprising: a mounting element for engaging with the sloping threads of a mating male end inserted in said second female end; said mounting element comprising a pair of spaced-apart fork elements, each said fork element having an elongated interior surface facing the elongated interior surface of the other said fork element; at least one sloping elongated linear thread element formed in each said elongated interior surface for engaging with the sloping threads of a mating male end inserted in said second female end and on opposite sides thereof; said main wall of said second female end comprising a pair of diametrically-opposed channels for sliding therethrough said pair of spaced-apart fork elements, a respective said fork element being slidingly received in a respective one of said pair of diametrically-opposed channels; said main housing further comprising a pair of diametrically-opposed, interior cutout portions that cooperate with the hollow interior of said pair of diametrically-opposed channels and with said hollow interior of said second female end, a respective one of said pair of diametrically-opposed, interior cutout portions being associated with a respective one of said diametrically-opposed channels, said pair of diametrically-opposed, interior cutout portions exposing said at least one sloping elongated linear thread element of each of said pair of fork elements to said hollow interior of said second female end; said interior cutout portions being arcuate-cutout sections of said inner circular wall portion of said second female end, each said interior cutout portion extending arcuately such that a portion of a respective said at least one sloping elongated linear thread element projects interiorly and radially inwardly through a respective said interior cutout portion into the interior of said second female end; each said fork element comprising a first end and a second cantilevered end; each said at least one elongated linear thread element sloping downwardly in a direction from said second cantilevered end toward said first end; said elongated linear thread elements being capable of wedging a male end inserted in said second female end as said fork elements are slid in said channels.
