Device with rotating spacer for applying paints to flat objects with the aid of a spray gun or a sprayer.

The innovation relates to a device with a rotating Spacers for applying varnishes, paints, mineral coatings, impregnating agents, etc. to flat Objects such as masonry, building walls, roof gables, Holaver cladding, containers for liquids, silos, etc. with the help a spray gun or sprayer.

When painting with common tools or spray guns, especially on wall and ceiling surfaces high buildings, containers and other structures, one is almost always forced to either use a ladder, or to use scaffolding to reach those areas of the surface that are exposed from the ground or another location (e.g. balconies, Terraces etc.) are no longer accessible

Working with ladders is not only time consuming because after every work step on a certain, relatively small area is the work step for adjusting or moving the ladder has to be interrupted, in many cases a sufficient paint quality is no longer given because the worker is forced to take care of his own safety. Because «working on ladders is always dangerous, besides that Eebr high areas with a simple leaning or step ladder usually not be reached.

The construction of scaffolding for painting work on large-area objects is only possible with high "personnel ·" and high costs. In addition, special measures are required for QerUste rielfaoh, which concern the protection of streets and sidewalks.

Paa working with useful tools (brush, paint application roller) with the help of extension handles only possible to a limited extent, since with increasing length of the extension handle a controlled tool guidance is no longer given. Eb also lacks that to achieve an equal Hessigon, Working pressure required on all sides with a coat of paint.

The innovation is based on the previously discussed economic, qualitative and safety-related deficiencies in the production of paints on surfaces, that are not accessible from the ground or another fixed given location.

The solution to the problem is that a spray gun or a spray device known or any Design by means of a holder at the end of a telescopically extendable or bayonet-like extendable handlebar is attached. With the help of a rotating spacer attached to the bracket below the nozzle the spray gun or the spray device for flat paint application by moving the handle up and down over the guide the object to be treated in a controlled manner. The rotating spacer rests on during the work process the object surface. In a lateral direction, it is offset in strips or in a zigzag course.

The usual paint application roller has proven to be a particularly suitable rotating spacer in the sense of the innovation.

The rotating spacer, whose axis of rotation is perpendicular to the DU axis, is on the bracket for the spray gun (or spray device) e.g. in a tubular chair or another suitable fastening mechanism in the direction of the object surface, so that it can be moved and locked without stopping. This allows the distance between the nozzle and the object surface, depending on the consistency of the coating material, or depending on the type of Push in the inserted nozzle so that the spray cone is free can unfold. So that the spray cone is always perpendicular to this When the object surface hits, the holder for the Sprltapieto-Ioj is adjustable on the upper end of the handle.

The rotating spacer whose axis of rotation is in norwiler Working position is horizontal and thus, as seen by the operator, a right angle with the handle «! Form-t, can be rotated as desired in the fastening mechanism (propeller-like), i.e. any angle can be used between the axis of rotation and the handle. This setting option also allows you to hold the Support stem to leave the axis of rotation of the rotating spacer in a horizontal position. This enables the operator to take up a position to the side and still the device described sank vertically move up and down

In this special case, but also with normal handling, the support pressure of the spacer prevents the entire device from sliding sideways.

If the rotating spacer is designed as a paint application roller, any paint that may run off is blocked by the Role picked up and evenly distributed again. Spray material that drips off the nozzle is also caught by the roller or fed to the roller via a drip tray for further distribution.

An electrical or mechanical switching device that can be worn at the end of the handle or on the body of the operator allows the application of paint to be switched on and off, such as

the work technique requires "

In many cases it is necessary to clean the surface of dust, soot or other dirt before applying paint, or alta * loosely adhering: remove paint residues. With the innovation, this work can also be performed. Instead of Spray gun (or sprayer) are then nozzles or Nozzles from steam jet devices, high pressure cleaners or other suitable cleaning devices «»! attached · The workflow is the same: as described for the paint application.

The new device has the consequence that perpendicular «or at an angle flat objects, even those of considerable height, from the ground or another fixed location, can be processed by just one person with precise tool guidance without ladders and scaffolding.

An exemplary embodiment of the innovation is shown in FIGS. 1-3

the operator can use the spray gun at will from the 'ground' on and off.

With differently designed spray guns or spray devices he follows switching on and off analogously, e.g. by regulating the compressed air supply by means of a tap.

In the event that the distance (e) of the nozzle (23) τοη the object surface (11) is smaller than the diameter (d) of the spacer roller (5), any paint dripping from the nozzle (23) is directly from the roll (5) picked up and spread over the surface.

The construction shown in Fig. 1 adapts to the variable distances (e) automatically.

Fig. 2 shows the device at. normal working conditions viewed perpendicular to the object surface (top view). The extendable holding handle (7) is held vertically by the operator in a top view. The axis of rotation (5 ') of the rotating spacer (5) is horizontal. The angle ( β ) between the axis of rotation (5 ') and the holding stem (7) is 90 in this case. The; Working direction (AE) runs vertically.

In Fig. 3, the device position is shown with the operator at the side. The inclination of the hold. Stems (7) is necessary, for example, if the operator cannot take a position directly under the surface to be worked due to obstacles or other reasons. In this case, the extended stem ( ² O of the rotating spacer (5) in the holder (2) is rotated so that the working position of the axis of rotation (5 ') of the spacer roller (5) is horizontal. Thus, the working direction (AR) also remains in this special case vertically.

is, especially since the most diverse forms of such systems are available from the Harkt.

The innovation can also be used to clean surfaces that normally can only be reached with ladders or from scaffolding, regardless of whether the cleaning is carried out in the Is or is not related to a subsequent coat of paint. The spray gun or sprayer is then cleaned by a cleaning device commercial type (steam jet, liquid high pressure sandblasting compressed air device etc.) replaced. It goes without saying that the above for the order The descriptions given for paints also apply in full to the cleaning of flat objects «.
