Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Further advantages and embodiments arise from the attached drawings.

(2) The drawings show:

(3) FIG. 1 a diagrammatic, detailed depiction of an apparatus for spreading fluids;

(4) FIG. 2 an exploded view of the apparatus shown in FIG. 1; and

(5) FIG. 3-5 three depictions of a fixing device.

DETAILED DESCRIPTION OF THE INVENTION

(6) FIG. 1 shows a partial, sectional depiction of an apparatus 1 according to the invention. This has a tubular body 6 which serves to conduct a fluid, for example a pesticide. This tubular body 6 has a side opening 62 through which a fluid medium can pass into an outlet device, designated as a whole with numeral 4. Reference sign L designates a longitudinal direction of the tubular body.

(7) The outlet device described in more detail below comprises a spring device 18 which may for example preload a nonreturn valve. In this way, it is possible that fluid can only emerge from the outlet device above a specific pressure.

(8) FIG. 2 shows an exploded depiction of the apparatus shown in FIG. 1, it is clear that the outlet device has a clamping mechanism which allows the outlet device 4 to be clamped to the tubular body 6. To this end, the clamping mechanism comprises a first clamping part 42a and a second clamping part 42b. These may be arranged around the tubular body 6 and screwed together so that as a whole the outlet device 4 is attached to the rod-like body 6. The first clamping body 42a has a recess 38, and the second clamping body 42b has a recess 36, which together at least partially surround the tubular body 6. Reference sign 32 designates seats for the screw bodies which may be introduced from the outside in order to screw the two clamping bodies 42a and 42b together.

(9) Reference sign 34 designates a contact portion which in a mounted state presses against the tubular body 6. Reference sign 64 designates a sealing device by means of which a seal may be created between the clamping body 42a and the tubular body 6. Reference sign 54 designates a carrier which serves to receive a nozzle device 46 and an auxiliary nozzle portion 52. Reference sign 56 designates a seat in which the nozzle device 46 may be inserted.

(10) FIGS. 3 to 5 show the fixing mechanism by which the apparatus may be arranged on a vehicle. A carrier 12 is provided, which for example can be bolted to a region of the vehicle. Reference sign 20 designates a holding device which serves to hold the tubular body 6. To this end, this holding device has a sleeve 22 which is suitable and intended for receiving the tubular body 6. The tubular body may be inserted in this sleeve and be screwed thereto, e.g. via a screw connection 23. It would however also be possible for the tubular body to be pressed into or engage in the sleeve 22.

(11) Reference sign 2 designates a supply line via which a fluid medium may be supplied to the tubular body 6. Reference sign 16 designates reinforcing webs. Reference sign 26 designates a pivot element for pivoting the holding device 20 relative to the carrier 12. A flexible body such as a hose 70 is arranged between the connection and the tubular body to conduct the fluid.

(12) Reference sign 14 designates an elongate protrusion which is formed integrally on the holding device 20 and which, in a predefined pivot position, can be guided through an opening or receiving groove 12a formed in the carrier 12.

(13) FIG. 5 shows an exploded view, wherein again the carrier 12 is depicted and also a receiving groove 12a in order to receive the element 16 in a pivotable manner. In the position shown in FIG. 5, the protrusion 14 and the receiving groove 12a run parallel to each other, so that in this position the holding device 20 may be removed from the carrier. The protrusion 14 is preferably arranged on a circular bolt.

(14) The position shown in FIG. 5 is therefore a position which is not assumed in a working operation of the apparatus according to the invention. The user may however pivot the tubular body into the position shown in FIG. 5 and then remove the holding device 20 from the carrier 12.

(15) Alternatively, as shown in FIG. 2, the outlet device may comprise a second sleeve, nozzle device and auxiliary nozzle portion.

(16) The applicant reserves the right to claim all features disclosed in the application documents as essential to the invention where novel individually or in combination relative to the prior art. It is furthermore pointed out that in the individual figures, features have been described which may be advantageous in themselves. The person skilled in the art will immediately gather that a specific feature described in one figure may also be advantageous without the transfer of further features this figure. The person skilled in the art will furthermore gather that advantages may result from a combination of several features shown in individual or in different figures.
