Hose coupling
First Claim
1. A hose coupling comprising at least two axially interconnectable members, including at least one male and at least one female portion, and having therein retaining means for releasably interconnecting at least one pair of said members, comprising in combination:
- a plug portion (1, 56,
63) having a shank region (14) therealong and a circumferential groove (15) in the latter; and
a connector portion (2) axially interconnectable with said plug portion, and having at least one recess (23) therein, said plug and said connector portions having a substantially common longitudinal axis when interconnected, each said at least one recess including a cavity;
a corresponding number of pivotally supported claws (20) in the latter, that constitute part of said retaining means, said claws each having a generally lengthwise axis oriented substantially transversally to said substantially common longitudinal axis, and being adapted to engage said groove when said plug and said connector portions are interconnected, each said claws including at one end a foot (21) mounted in said cavity and at the other end shoulder regions (26) and curved stop noses (32);
said connector portion including a tubular main body portion (19) having through slots (25) at one end and edges (31) at another end, said shoulder regions (26) protruding through said slots for engagement with said circumferential groove, said noses (32) resting against said edges; and
a single manually operable pressure member (33) slightly protruding from said connector portion and having a generally lengthwise axis oriented substantially transversally to said substantially common longitudinal axis and to the axis of said claws, the axis of said claws and said single manually operable member being normal to each other, said pressure member including means acting on said noses for releasing upon operation the interconnection between said plug and said connector portions, by moving said claws out of the engagement with said groove.

Abstract
Hose coupling of the kind having at least two axially interconnectable members, with retaining means for releasably interconnecting at least one pair of the members, comprising a plug portion and a connector portion, and a manually operable pressure member slightly protruding from the connector portion for releasing the interconnection between the plug and the connector portions; wherein the plug portion has a shank region with a circumferential groove therein; while the connector portion has at least one recess therein, with a corresponding number of claws in the latter, that are part of the retaining means, adapted to engage the groove in the shank region of the plug portion. The invention also relates to a handle-shaped embodiment of the plug portion, and to a distribution box that can have several outlet branches. Any of the inventive members of the hose coupling may have a hose clamp attached thereto, leading to an external consumer point.
