This object is achieved by a foot having the features of claim 1, wherein the foot according to the invention comprises: a cup-shaped receiving region for the telescopic lance, which is adaptable to different sizes of the telescopic lance, a, in particular cylindrical, connecting region, the at least one lateral recess for the implementation a fluid supply line, and a, in particular dome or hemispherical, end portion, which is designed for setting up the foot on the floor.

Due to the spatial separation of the areas for producing the ground contact and for carrying out the fluid supply line a risk of kinking the line is prevented in the foot according to the invention. In addition, the end can be made of a material that prevents damage, noise and shock.

The present invention also relates to an arrangement which comprises a telescopic lance which can be coupled to a device for cleaning and / or processing objects by means of a fluid, and a foot according to the invention.

Further embodiments and advantages of the invention are also set forth in the dependent claims, the description and the drawings.

The invention will now be described by way of example with reference to the drawings. Show it:

1a schematically an embodiment of a foot according to the invention with a recorded portion of a telescopic lance, and

1b schematically a telescopic lance with a foot according to the invention.

In the 1a shown embodiment of the foot according to the invention 10 includes a sleeve-shaped receiving area 12 for a telescopic lance 14 , a cylindrical connection area 16 and an end area 18 ,

The end area 18 is hemispherical or dome-shaped and, in particular 1b can be removed to set up the foot 10 provided on the floor.

The end region is preferred 18 made of an elastic material, in particular rubber, so that due to the elasticity of the material, the risk of damage, noise and shock is reduced.

Except the end area 18 can also other areas of the foot of an elastic material such. B. rubber be made. In particular, the entire foot could be 10 be made in one piece from such a material.

The end region is preferred 18 from a separate, with the connection area 16 formed coupling member, wherein the coupling can be carried out particularly preferably by plugging together. This allows a particularly simple assembly of the foot.

The connection area 16 has an elongated recess extending parallel to its longitudinal axis 20 through which a fluid supply line 22 is guided. The shape of the recess 20 is basically arbitrary. The administration 22 serves to a working fluid (especially water) from a fluid source, not shown, for. As a high pressure cleaner, through the lance 14 through a processing device, also not shown, for. As a cleaning brush assembly to supply, during operation at the upper end of the telescopic lance 14 is appropriate. The recess 20 or one possibly additionally in the connection area 16 trained further recess may also serve to another supply line, for. B. an electrical Connecting cable to supply the processing device.

The recording area 12 is due to the size of the telescopic lance 14 adapted, ie dimensioned such that the lowest, the largest diameter portion of the lance 14 in the recording area 12 is inserted, and in particular substantially fit or clamping, so that the foot even when lifting the lance 14 is held securely. In addition, fastening means may be provided. It is Z. B. also possible to screw the foot to the section of the lance.

Such an adaptation of the receiving area 14 to the size and in particular to the diameter of the telescopic lance 14 For example, by one or more, in the 1a not shown, cup or sleeve-shaped inserts are achieved, which can be removed for resizing. In an alternative embodiment, the receiving area 12 before the first use by a single, irreversible machining to the diameter of the male section of the telescopic lance 14 customized. For this purpose, for example, within the receiving area 12 Material z. B. in the form of a lattice-like, integral plastic insert or in general, however, be provided as any concretely designed ribbing. By partially removing this material, for example, by milling, turning or drilling, the inner diameter of the receiving area 12 before the first use in a simple manner to the size of the respective telescopic lance 14 be adjusted.

The receiving area is preferred 12 and the connection area 16 formed integrally with each other and formed by a plastic part produced by injection molding. As a result, the foot can be easily and inexpensively manufactured in particular in large quantities. In particular, the above-mentioned size-adjusting integral insert may be used in the manufacture of the receiving area 12 and the connection area 16 be formed with the integral one-piece component.

This plastic injection molded part then needs before delivery only with the end 18 provided and to the size of the respective lance 14 be adapted in the manner explained above.

The use of the foot according to the invention and the arrangement according to the invention are not limited to telescopic lances and supply lines for a fluid. Also not variable in length, basically serving any purpose, in particular elongated objects can be provided with the foot according to the invention and supported on the ground. The recess may also serve to perform one or more other supply lines.

The end can be used as a lid for a z. B. be provided in the connection area provided storage space, which is accessible when removed end. For example, accessories can be accommodated in the foot in this way so that they are not lost and always available.

Furthermore, it is possible to use the foot in addition, namely as a carrier for z. B. information varying from customer to customer. In particular, the foot can be used as an advertising medium. For example, a manufacturer of the foot may offer individualized feet to his various dealers, each bearing the logo and / or the name of the particular dealer. In this way, the fact can be exploited that in practice often the telescopic lances themselves do not come as an information carrier in question, since the material from which these lances are usually made as a permanent support for z. B. image or font prints is unsuitable.

So z. B. be provided for the foot of a modular structure such that for use as a carrier for information to be varied as needed at least one component is interchangeable. For example, for each customer of the manufacturer of the foot, a specially designed or printed end area or connection area can be selected so as to achieve the desired individualization. It can, for. B. also be only the connection area itself, which has the modular structure and z. B. consists of several rings or sleeves, of which at least one is interchangeable and thus can be selected customer-specific.

Alternatively or additionally, a region may be provided on or in the foot, which is designed to accommodate, in particular, a replaceable receptacle of at least one separate information carrier. So z. B. may be provided in the form of a pocket receptacle into which a suitably sized, flexible or flexible card can be inserted, which serves as an information carrier. A sleeve forming the receiving area of the foot for the lance can, for. B. be provided with a extending over a certain region of the circumference opening through which a z. B. inserted information carrier as through a window is visible. The insertion can take place in the axial direction on the receiving side between the radial, provided with the "window" outer wall of the receiving area and serving for resizing to a respective telescopic lance material ribbing or grid structure
