DIPL-JNG.CURT WALLACH DIPL-ING. GONTHER KOCH DR.TINO HA (BACH MUNCHING 23 times 1969 UNIHZBCHfN, H 8? 2 - W / Κβ Wolf Devices GmbH., Betzdorf / Sleg Plug-in coupling for hoses, in particular garden hoses

The invention relates to a plug-in coupling for Hoses, which is particularly advantageous for garden hoses and is characterized by its simple structure and by characterized by their ease of use. The coupling can also be designed so that it can be used for hoses of various diameters.

An embodiment of the invention is based on the Drawing described. In the drawing show:

Fig. 1 is a half shown in longitudinal section coupling according to the invention in the assembled, but not yet locked state,

Flg. 2 the same coupling in the assembled state, but shortly before the final locking; the locked position can be seen from Fig. 2a,

3 shows the same coupling during the release of the coupling parts shortly before unlocking,

Pig. 4 the same coupling while releasing the coupling parts, at the moment of unlocking,

Fig. 5 is a section along the line V-V of Pig. I.

As can be seen from the drawing, the hose ends 7 and 8 are each pushed onto a cylindrical inner part 1 and 6, which are designed conically at their outer ends for this purpose. At their other, cylindrically designed parts, the two parts interlock, namely the cylindrical extension I ^{1 can be} displaced in the cylindrical extension 6 ', a sealing ring 16 providing the required seal.

The hose end 7 is on the conical extension of the inner part 1 by an annular sleeve 2, the hose end 8 on the conical extension 6 clamped by a sleeve 5, which is used to distinguish it from the ring sleeve 2 in the following as a locking sleeve 5 is designated.

On the ring sleeve 2, an outer sleeve 3 is slidably mounted, which is under the pressure of an inserted helical spring 15 in the in Pig. 1 position shown is moved, in which the inner collar 18 of the sleeve 3 against an outer collar 17 of the ring socket 2 comes to rest. In order to be able to place the sleeve 3 on the ring sleeve 2, as in the section after Pig. 5 it can be seen, in the collar 18 distributed on the circumference grooves and provided in the collar 17 corresponding cams, see above that the sleeve 3 can be pushed onto the sleeve 2 in a certain mutual rotation of the parts 2 and 3. Then both parts are twisted against each other a little.

In the other direction, the helical spring I5 serves as a stop for the sleeve 3, as shown in FIG.

Grooves are also provided on the collar I7, distributed around the circumference, in which several, in the example shown, eight locking fingers 4 are inserted, which are displaceable in the longitudinal direction and in one end position the position according to FIG. 1, in the other end position the position according to Fig. 4 take. At their free ends, the fingers have 4 locking claws which, with their inclined surfaces, have corresponding locking fingers 5 ^! work together, which are provided on the locking sleeve 5.

In order to bring about the locking, the two coupling parts are shifted against each other by hand, the fingers 4, which at their rear end lie against a collar surface 9 of the ring sleeve 2, bend elastically upwards, as shown in FIG. By virtue of their elastic spring force, as shown in FIG. 2a, the claws of the fingers 4 then grip the corresponding claws of the fingers 5 ¹ , the fingers 4 moving relative to the ring sleeve 2 into the position shown in FIG. 2a, in which they come to rest on a stop surface 10. In this position, the inwardly protruding peripheral surface 11 of the outer sleeve 3 is located above the surface 12 of the locking claws of the fingers 4, so that they cannot move outward and the engagement of the two-sided claws 4 or 5 ^{1 is} locked (Fig. 2a) .

To release the lock, the outer sleeve 3, as in Pig. 3 shows a small piece on the ring socket 2 shifted upwards, the compressed helical spring acting as a stop for the collar l8 and the annular surface 11 now-

more the locking claws of the pinger 4 releases. at further displacement of the outer sleeve 3 (outward), the pingers 4 are held by the stop 10 so that, as shown in Fig. 4, the fingers 4 can move outwards and finally the coupling parts in turn not assume more locked position according to Fig. 1, from which they can be completely pulled apart.
