Abstract

A connector (1) for flexible fluid lines, such as garden water hoses, comprising a universal body member (3) which is common to all interconnecting components of the system, wherein there is a twist-together, twist-apart bayonet connection between component parts (1 and 7), wherein the locking lug (14) of the first component (1) engages a groove in the inner coupling member (8) of the second component (7), and the locking lug (14) of the second component (7) engages a groove in the inner coupling member (5) of the first component (1).

Claims

1. A connector for a flexible fluid line, comprising

a first universal body member having a passageway extending axially therethrough from one end to an opposite, outer end thereof, an inner coupling member coaxially disposed and fixed within said first universal body member having a passageway extending axially therethrough from one end to an opposite, outer end thereof, and a locking lug depending from a peripheral edge of the outer end of the first universal body member and having an inwardly directing flange about its outer end adapted to connect said first universal body member end to end with a second universal body member;

and

a second universal body member with an inner coupling member coaxially disposed therein and with a locking lug depending from adjacent a peripheral edge of the second universal body member interfacing with the first universal body member, wherein the first and second universal body members are mutually rotatable relative to one another to effect a bayonet-type coupling wherein the locking lug depending from the first universal body member is located in a peripheral groove formed in a side edge of the inner coupling member of the second universal body member, and wherein the locking lug depending from the second universal body member is located in a peripheral groove formed in a side edge of the inner coupling member of the first universal body member, whereby the outer end of the inner coupling member of the first universal body member interfaces and sealingly engages the outer end of the inner coupling member of the second universal body member.

2. A connector for a flexible fluid line as claimed in claim 1, in the form of a hose-end connector for attachment to a water tap or water cock.

3. A connector for a flexible fluid line as claimed in claim 1, in the form of a hose-end connector for attachment to an accessory attachment.

4. A connector for a flexible fluid line as claimed in claim 1, in the form of a coupling for interconnecting two flexible fluid lines or hoses.

5. A connector for a flexible fluid line as claimed in claim 1, wherein opposed O-rings;

are provided in the outer ends of the interfacing inner coupling members for sealing engagement therebetween.

6. A connector for a flexible fluid line according to any one of the preceding claims comprising part of a garden hose watering system.

7. The connector of claim 1, wherein the inner coupling members are snap-fitted into the respective first and second universal body members.

8. The connector of claim 7, wherein the universal body member passageways at the one end is threaded.

9. The connector of claim 8, wherein the inner coupling member has a hose connector portion disposed toward the one end which is adapted to engage the interior of a hose, and wherein the universal body member further comprises:

(a) a hose clamp collar threadedly disposed in the universal body member passageway and extending a predetermined distance out the one end, which is adapted for being disposed around the exterior of the hose, and (b) a hoselock circlip disposed in the universal body member passageway for sealing engagement between the hose clamp collar and a hose.

10. The connector of claim 8, further comprising a washer disposed in the universal body member passageway at the one end which abuts the inner coupling member.
