Swivel pipe outlet for fittings

The inflation relates to a rotatable in the connection piece a valve body held swivel spout for fittings. The aim of the innovation is that Swivel tube or the like without using additional fasteners such as union nuts. and in particular, easier and more reliable Y / iron to attach in the connection piece.

Accordingly, the novelty is essentially seen in the fact that in the fastening end of the swivel tube a tube-like Connector inserted with a laterally protruding pin and through its bayonet-like Engaging in corresponding grooves in the connecting piece is rotatably coupled to this A particularly expedient embodiment consists in the fact that for the engagement of the coupling pin in the connecting piece "an annular Turning as well as a subsequent additional turning that is limited in the circumferential direction is provided, the end faces of which each have a stop for the introduced therein and the swivel area; of Form Hohrauslaufes limiting coupling pin. the annular recess can be connected to the additional recess in a suitable manner, and e.g. as just one

Over half the circumference extending parallel groove or as a widening of the recess be trained.

In addition to the advantages already mentioned, the installation work can be carried out in a very short time In economic terms, a significant cost saving achieved and at the same time when using Risk of damage to chrome-plated parts that exist with tools is avoided.

In the drawing, the innovation is shown in two exemplary embodiments. Show it

1 is a valve body, in the connecting piece 2 of which a swivel tube 3 is rotatably held. To this end is a sleeve-shaped in the fastening end of the tube 3 Connector 4 used, the annular grooves 5 for receiving sealing rings 6 and on which the Swivel tube 3 adjacent end part with a laterally

is provided on the jacket surface protruding pin 7 (see. Pig. 2 and 3).

The connecting piece receiving the connecting piece 4 has a connecting piece which is used to engage the coupling pin 7 annular hat 10, to which one is attached in the front End face of the connecting piece 2 opening and for inserting the pin 7 serving longitudinal groove 12 connects. The coupling pin 7 can instead of a one-piece design also consist of a pin screwed radially into the connector. In this embodiment, a simple insertion and removal of the achieved with the connecting piece 4 provided pivot tube 3 in the manner of a bayonet lock, wherein the Tube 3 is rotatable through 360 °.

In the example shown in Pig. 4 to 6, the Rohrschwenkbereieh limited to only about 180.

In this case, the pin 14 of the connecting piece 4 is initially in / relatively wide annular through a longitudinal groove 15 Notch 16 introduced (see dash-dotted position I in Pig. 4), in which the tube 3 can be rotated without restriction can. To limit the rotary movement to about 180, the recess 16 is in the direction of the -a ^ BF-nozzle opening with an additional recess 17, which however only extends over approximately half the circumference provided (see Pig. 5). The one parallel to the nozzle axis

lying end faces 18,19 of the recess 17 each form a stop for the pin 14 »if this jau-aacfrgS by a small rotation (angle χ in Pig. 5) removed from the area of the longitudinal groove 15 first in the dash-dotted line Position II (Pig.4) and then by one opposite to the direction of insertion of the pipe 3 pull exerted in the limited indentation 17 in the dot-dash position III (Pig. 4 and 5) is brought in.

In this position, both the rotation of the swivel tube 3 limited to about 180 ° but also the pipe 3 itself secured against being pulled out of the socket 2. The backup can optionally be supported by a spring supported in the nozzle 2, which the inserted pipe end into the limited recess 17 presses in. If necessary, the pipe 3 can be removed from the socket 2 again in a simple manner be removed, in ^ by the pin 14 by a in the direction of insertion pressure exerted on the pipe end 4

which is introduced into the Kiögrort / 16 and then through a corresponding Rotation is brought to position I (Fig. 4), which is coaxial with the insertion groove 15.

Of course the firing is not on the one shown Examples are limited, for example, instead of the inserted sleeve, the swivel tube itself can have annular indentations 5 and / and a radially inserted pin being.

Claims (2)

P.A.2O2 92WU. Protection claims 1) Swivel pipe outlet for fittings, marked thereby, that in the fastening end of the pivot tube (3) a tubular connecting piece (4) with a laterally protruding Pin (7,14) inserted and, through its bayonet-like engagement, in corresponding grooves (10; 16,17) is rotatably coupled to the connecting piece (2). 2) swivel spout according to claim 1, characterized in that that for engagement of the coupling pin (Η) in the connection piece (2) an annular Einareiiung (16) and one with this connected, but in the circumferential direction "limited additional recess (17) is provided, the end faces of which (18,19) one stop each for the recess (17) form introduced coupling pins (14).
