Spray hose

The invention relates to a spray hose with several channels and over the length of the channels, spray slots that open under pressure and at the ends of the spray hose attached fittings.

Such spray hoses are used for the purpose of sprinkling or watering and are connected to a pressurized water hose or to a pressurized water hose Water pipe connected. The fact that the water supply in the spray hose to several channels, preferably three Channels is divided, a relatively even pressure distribution seen over the length of the spray hose can be achieved because the spray slides of the individual channels are arranged in different areas.

Since the spray hose is essentially "flat" in cross-section due to the juxtaposed channels, means must be used the fittings attached to the ends of the spray hose create a transition to those with a round cross-section Water pipes or water hoses can be reached. For this it is known to use the separators in which to attach the Cut through the end area of the spray hose provided for the armature and a round inner sleeve in this area insert so that the area with the severed webs to a circular cylinder enclosing the inner sleeve The middle section is widened. This section then goes in a transition area from "round" to the flat shape of the spray hose.

An outer sleeve with an annular cylinder-shaped area and flattened areas designed to match the transition area encloses the fastening area from the outside. The hose is firmly attached between the inner sleeve and the outer sleeve, for example by inserting the hose between the brass inner and outer Outer sleeve is pressed in.

The disadvantage here is that the fitting cannot be installed by laypeople, but rather only in the factory. As a result, the user cannot shorten spray hoses. But Dits is often desirable because Spray hoses should often be used in narrow, angled small areas, front gardens or the like ..

The invention is based on the object of creating a spray hose of the type mentioned with a fitting, which Even laypeople can easily cut it to an individual length, i.e. shorten it.

According to the invention, this object is achieved in that the fittings have plug-in nipples corresponding to the number of channels with inner channels, and the outer diameter of the nipple at least the inner diameter of the channels

• corresponds, and the plug-in nipples together on one as well Muzzle plate having through openings are attached, and the insertion area of a clamping device is enclosed. The advantage here is that the separating webs between the channels are not cut out in the end regions will need, but the Einstecknippsl inserted into the channels and through the clamping device acting from the outside to be held

A particularly good mounting and a particularly good sealing effect are achieved if the plug-in nipples protrude in a ring shape Have areas. In a further embodiment of the invention, the plug-in nipples are of different lengths. The ring-shaped formed areas are arranged at different points. This ensures that plugging in the Plug-in nipple is possible without mutual hindrance from the annular protruding areas.

According to a preferred embodiment of the invention it is provided that the clamping device as a slotted ring with external thread and with the number of channels corresponding, is formed in the position of use against the insertion area abutting recesses, and a screw sleeve with on the Has external thread screw-on internal thread, and the screw sleeve is designed in the manner of a union nut and has an annular shoulder intended to rest against a protruding web of the orifice plate and a hose connection part. The hose connection part is designed in an expedient embodiment as a plug connection part, so that a direct The fitting can be attached to conventional plastic water pipe systems.

The invention is explained below with reference to the in the drawing illustrated embodiment explained in more detail. Show it:

1 shows a schematic perspective illustration of a spray hose with a fitting arranged at one end, to which a connector can be connected;

FIG. 2 is a view corresponding to FIG. 1, in which the parts of the fitting are shown separately.

A spray hose denoted overall by 1 has three channels 2, 3, 4 which are separated from one another by separating webs 5, 6 are. The channels have spray slots (not shown) which open under pressure and which extend in sections over the length of the hose are distributed over the individual channels. At the end of the spray hose is a fitting designated as a whole with 7 appropriate. The fitting has a Mündungsplattc ö with a protruding web 9. Plug-in nipples 10, 11, 12 are located on the side of the mouth plate 8 opposite the web 9 arranged of different lengths, their spacing and outer diameter corresponds at least to the inner diameter of the channels 2, 3, 4. The push-in nipples are at their front ends conically tapered and have inner channels which in through openings 13, 14, 15 of the orifice plate 8 flow out. The plug-in nipples are still with. annular protruding areas 16, 17, 18 are provided.

In the position of use, the nipples 10, 11, 12 are inserted into the channels 2, 3, 4 in such a way that the mouth plate 8 lies in the front end area of the spray hose 1. Then the hose area pushed onto the plug-in nipple is locked from the outside by means of a clamping device. This clamping device is in the exemplary embodiment shown as a slotted ring 19 with a slightly tapered external thread 20, a slot 21 and a Flange part 22 is formed. Furthermore, the part 19 has on the inside recesses 23, 24, 25, the number of which corresponds to the number of Corresponds to channels 2, 3, 4 and whose shape is matched to the design of the upper side of the sole. On the recesses 23, 24, 25 opposite side of the slot 21, no recesses are provided in the embodiment shown, because the spray hose shown is continuously flat on the underside.

The screw sleeve also has a Hose connection part 30 designed as a plug connection part.

The fitting enables quick coupling with known plastic coupling systems.

The fitting 7 can easily be assembled or disassembled even by laypeople. For shortening a spray hose the screw sleeve 28 is unscrewed in the direction of arrow A.

The slotted ring 19 is then inserted into the position shown in FIG.

2 position shown pushed and then the muzzle plate 8 with the push-in nipples 10 to 12 pulled out of the hose channels in the direction of arrow B. The spray hose 1 can now be shortened to the desired length.

The assembly is then carried out in reverse order.
