Patent application .

Hose quick connect strap ;? ;

In patent application P 16 25 042.0 of the same applicant has proposed a quick coupling for Kohr- and hoses that guarantees cost, a particularly appropriate use for simple, reliable operation and low Services Process · _Λ gBjtäkilaixiB ± x. ]) These properties are brought about by a construction in which the nut piece has a locking ring, while the plug contains the actuating slide for opening and closing the coupling. Such an arrangement is particularly advantageous if the Lutterstäck are attached to the stationary line part (eg Y / water tap) and the plug is attached to the movable line part (eg water hose). It can also be used as a wiinuohonaword to attach the plug to the filed I ¹ eiJL and the nut piece to the respective cable. «^

In this case, it is appropriate with regard to ease of use to provide the piece with Hutter deci Eetäti & ungaschieber. This is achieved by the solution described below, which moreover offers the same Vortdile as a quick coupling according to the above-cited approach.

Install the connector and place it in a closed position can hold. The slide is designed as a üin ^ ", dor Slid over the piece of food and locked in place so that it cannot be leashed wlvd. With SohrtttfflUohen he embraces the antaproohonde Tolle Tongues in such a way that they are spread unct out of the connector groove be released, if you pull it in the direction facing away from the stooker. The inclined surfaces can be ic the rest are basically on the slide, on the tongues or on both parts. Suspension of the tongues and inclined surfaces cause the slide to return after pressing nelbut returns to its original position. The tongues are spread apart before they snap into place by the corresponding Place conical connector. The seal is achieved by an O-Hing (or /. Cuff) on the mandrel stacker and a sealing surface in the liner or vice versa.

When joining the nut piece and plug, the Soil not actuated to earth. At the loaon of the connection becomes "the mother piece and thus the movable line The slide is detected and removed from the plug. The actuation therefore takes place in the same direction as the movable one Line is removed from the coupling.
