Description

The invention relates to a device for applying flowable media an area according to the preamble of independent claim 1.

Such a device is known from document US-A-4152084.

In the prior art, this is the case with cleaning and maintenance measures Detergent, disinfectant or care product from an appropriate Product containers directly on the preferably smooth, flat or slightly inclined surface, for example, poured the floor. The agent can also be in a container be diluted and poured onto the floor as a diluted application solution become. An example of the previous way of working is given here Dispersion application briefly described.

To fill up the dispersion, the worker has to change constantly bend deeply to pour the dispersion onto the floor and your torso Tilt strongly forward and twist at the same time to make the product even to distribute. With this procedure, only a sub-area of the Area to be worked on until the filled amount is processed. Frequently this work was also carried out by two people, one of whom was the dispersion on the area to be processed and the other the dispersion equally distributed. In any case, there is a constant, time consuming and tiresome change between the different work processes. On continuous work, which is an essential requirement for the constant quality of the order is not possible. Are known in State of the art application devices in which the media in the containers pressurized and led out of the container. The Flow rate and flow rate are affected and during pressure reduction reduced in the container so that a longer continuous and even, effortless work is not possible.

Devices described in the introduction are also known in the prior art, for example in DE 39 05 760 A1. The containers are on the stem of the Wiping or application device attached. So it is possible, at least to alleviate some of the difficulties of the described procedure. However, at the same time the handling of the wiping or application device becomes complete considerably more difficult because the attachment of the container to the handle is very difficult unfavorable and constantly changing balance of gravity conditions. In addition, the size and shape of the container is strong with this attachment limited or restricted and changing and refilling or refilling the Container very cumbersome and difficult, so that the use of commercial Container is hardly possible or only with great difficulty.

The invention is based on the technical problem described above Develop the device so that the disadvantages avoided and simple and an inexpensive way to continuously process as large as possible Surface enabling device is created.

This problem is solved by the features of the characterizing part of independent claim 1 solved.

This device has the advantage that even larger amounts of the to be applied flowable media can be carried by the operator since their Arrangement on the back of the operator to do the work when applying not hindered or impaired and therefore larger areas be continuously and seamlessly processed by an operator can. It is also advantageous that the container can be easily readjusted or can be refilled without the hose adapter from the Outlet opening would have to be removed. Furthermore, it is advantageous possible, at the end of a processing section the rest of the to leave used medium in the container when the outlet opening after Removing the hose adapter is closed by a cover.

In the proposed device, two different types of containers can be used to be used. For this purpose, the Container coupling elements on the quick coupling device of the Mounting plate are matched. In another embodiment, those are based on the Quick coupling device of the mounting plate coordinated Coupling elements provided on a container receptacle. In this Containers can be used with standard product containers and thus carried on the back of the operator with the aid of the receptacle become. If the container has the coupling elements, it is as Universal container in which the appropriate media from the commercially available product containers.

An embodiment in which the hose adapter is a is particularly advantageous locking system matched to the connecting piece of the outlet opening, for example, has a screw or bayonet lock. Will be expedient the closure system designed so that it is commercially available on the closure Container fits so that the same hose adapter both on the outlet opening of the universal container as well as on the outlet opening of the product container can be put on. The hose adapter advantageously has a Venting element on, so that the container is not a separate venting device needed for pressure equalization and the container at the end of the Processing process after removing the hose adapter directly in pressure-balanced state closed again by the cap can be.

In an advantageous embodiment, the universal container has a Filling opening in the shape and / or size for the filling of the media is suitable without a funnel or similar means and which by a Closing lid is closable. This makes it possible to read the medium Refill consumption of the originally filled amount without the container need to change or the hose adapter or the line to Remove continuation of the medium to the line outlet. As a result of that Universal container and container holder both identical coupling elements have that matched to the quick coupling device of the mounting plate are, it is also possible to quickly and easily use the universal container against one Exchange container holder with standard product containers and vice versa.

In a special embodiment, the universal container has a Level marker on the level for a solvent, for example Water, indicating that the amount of solvent corresponding to this level is to be dimensioned so that it with a predetermined amount of concentrate, the one for the respective medium prescribed and advantageous concentration or Dilution guaranteed. This makes it possible for the operator to Example of water-soluble concentrates only the corresponding one Basic concentrate quantity in a dosing cartridge or another Dosing container must be carried and then on everyone in the object to be processed existing water connection a new tank filling in the desired Can prepare concentration. If the refill cartridge or another Dosing containers have a special closure, a separate one Connection device for this closure conveniently in Cap of the filling opening provided.

So that the product or medium does not flow out of the pipe outlet if the drop height is too great or if the distance from the is too short overlapping the working area with the wiping or application device is the Outlet opening in one on the product or medium and its consistency coordinated distance above the surface.

The metering valve for regulating the flow of the product is expediently between Hose quick coupling and the outlet of the line on or at the wiper or Application device arranged so that after removing the line or of the hose from the hose adapter the amount still in the pipe the desired flow rate can be applied. It is advantageous if the hose quick coupling has a run-on protection that for example spring-loaded or by a ball or the connection in some other way closes to the container so that even without actuating the shut-off device after removing the hose / or the pipe no more product from the Container flows.

The proposed device enables simple and ergonomic Favorable handling for a wide range of applications with high Area performance and low consumption of product / media. Product loss will largely avoided because standard product containers are used can and when changing containers or cleaning the device only small Product residues (disposal) are incurred because product residues are usually sealed containers can remain.
