Abstract
A coupler for coupling a male end of a hose to a female end of a faucet or another hose. In the first embodiment, the female end of the coupler is mechanically locked in sealing engagement with a male end by simply translation thereof by means of wedges and an outer retaining sleeve. In a second embodiment, hydraulic pressure provides the final seal, with the female end being a spring split-ring locked and compressed by means of an outer locking sleeve, which outer locking sleeve is released by squeezing it in order to deform it. A third embodiment combines the first and second embodiments.
Claims16
A coupler having a female-end for connection to a male-end of an element, comprising:
- a main frame;
- a collet means mounted for translational slidable movement by said main frame, said collet means comprising flexible engaging means for engaging a cooperating portion of a male-portion of an element;
- an outer retaining member mounted for translational sliding by said main frame, said outer retaining member being at least partially telescopingly movable about said collet means for preventing said flexible engaging means from disengaging with the male-portion of an element, and comprising first engaging means;
- an inner retaining means mounted by said main frame for relative translational sliding motion with respect to said outer retaining member, and comprising second cooperating means, said inner retaining means capable of retaining said outer retaining member in a retained position via said first and second cooperating means;
- means for translating said flexible engaging means of said collet means;
- said means for translating comprising third cooperating means in operative association with said collet means and said outer retaining member for alternatively moving said collet means in a first direction and in a second direction.

In a coupler having a female-end for connection to a male-end of an element, comprising:
- a main body portion;
- collet means mounted for translational slidable movement relative to said main body portion, said collet means comprising flexible engaging means for engaging a portion of a male-portion of an element;
- an outer retaining member mounted for translational sliding relative to said main frame and also relative to said collet means, said outer retaining member being at least partially telescopingly movable about said collet for preventing said flexible engaging means from disengaging with the male-portion of an element, and comprising first engaging means;
- retaining means capable of holding said outer retaining member in a locking position;
- and
- intermediate means for slidably moving said flexible engaging means of said collet means toward and away from said main body portion;
- said means for moving comprising wedge means having a first wedge-surface, a second wedge-surface and a third wedge-surface;
- said main body portion comprising a first canted-surface means for contact with said first wedge surface of said wedge means for movement of said wedge means therealong;
- said outer retaining member comprising a second canted-surface means for contact with said second wedge-surface of said wedge-means;
- and said collet means comprising engaging surface means for contact with said third wedge-surface;
- said wedge means causing said collet means to move relative to said main body portion by said contacting third wedge-surface and said engaging surface means when said retaining member is moved relative to said collet means by contact of said second canted-surface means with said second wedge-surface of said wedge-means.

A method of coupling a male-end of an element, comprising:
- (a) inserting a male-end into a flexible, floating collet member having mating engaging means for the male-end;
- (b) said step (a) comprising pushing the male-end thereagainst to cause the engaging means of the collet member to initially engage with the male-end inserted therein and for translationally moving the collet member a first lateral distance by contact of the collet means against a limit-stop;
- (c) after said step (b), allowing the collet member additional translational lateral movement;
- (d) said step (c) sealing the male-end against the sealing member;
- (e) said step (c) comprising moving the limit stop a distance that allows said additional translational lateral movement.

- an outer retaining member mounted for translational sliding relative to said main frame and also relative to said collet means, said outer retaining member being at least partially telescopingly movable about said collet for preventing said flexible engaging means from disengaging with the male-portion of an element, and comprising first engaging means;
- retaining means capable of holding said outer retaining member in a locking position;
- and
- intermediate means for slidably moving said flexible engaging means of said collet means toward and away from said main body portion;
- said outer retaining member comprising a first cooperating means;
- said retaining means being mounted by said main body portion for relative sliding motion in said outer retaining member, and comprising second cooperating means;
- said retaining means comprising a compressible member capable of holding said outer retaining member in a locking position via said first and second cooperating means;
- each of said first cooperating means and said second cooperating means comprising means for compressing said retaining means, and further comprising cooperating locking means for locking said outer retaining member in a position relative to said compressible member for keeping said compressible member in a compressed state.

In a coupler having a female-end for connection to a male-end of an element, comprising:
- a main body portion;
- collet means mounted for translational slidable movement relative to said main body portion, said collet means comprising flexible engaging means for engaging a portion of a male-portion of an element;
- an outer retaining member mounted for translational sliding relative to said main frame and also relative to said collet means, said outer retaining member being at least partially telescopingly movable about said collet for preventing said flexible engaging means from disengaging with the male-portion of an element, and comprising first engaging means;
- retaining means capable of holding said outer retaining member in a locking position;
- and
- intermediate means for slidably moving said flexible engaging means of said collet means toward and away from said main body portion;
- said retaining means comprising a compressible member having a first end-portion and a second end-portion;
- said collet means being capable of abutting contact with said second end-portion of said compressible member;
- said outer retaining member having means for compressing said compressible member when said outer retaining member is moved in the direction of said collet means, whereby when said compressible member is compressed, said collet means is allowed movement by said means for moving in a direction toward said main body portion to thereby secure a male-end held in said flexible engaging means.
