"Device especially for" cleaning window panels ¹¹

The invention relates particularly to an apparatus for cleaning window shades with a housing structure, which are arranged opposite one another at a distance from one another Nozzles for spraying cleaning fluids, cleaning elements arranged at a distance from one another and a support for holding a screen in an extended position, which of the cleaning elements is to be processed, the housing structure and the carrier being arranged for two relative movements,

so that the aperture between the spray dots and the in Rhythmic elements arranged at a distance from one another Can be moved.

The invention particularly relates to an apparatus sua cleaning τοη window blinds such as window blinds or the like.

Usually the sub cleaning procedure is such Blinds "if mere dedusting is not sufficient" so that they are either washed in situ, which is an unsatisfactory process, or that the bezels are removed to put them in place remove, in which they τοη can be hand washed and hung to dry. This last one Procedure has the consequence that the diaphragms from the pensters are removed for a considerable period of time, which is undesirable and generally unacceptable, The subject of the present invention is a simple but effective device for washing window shades, which accelerates the Wasoh process and considerably reduces the time in which the diaphragm must be away from the window.

Another object of the invention is such a device, which in a fora on a vehicle, For example, it can be placed on a trailer so that it can be accessed by the user on the property of the customer can be brought to be used there.

In the broadest sense and in one embodiment of the invention, the device for the described comprises Purpose a free-standing structure, which is spaced apart, opposing nozzles for spraying water and / or a cleaning liquid, rotatable, spaced apart, swingable or reciprocating cleaning elements and a support frame for holding a panel comprises in the extended position so that the latter can be processed by the cleaning elements of this structure can. The screen support can be moved between the nozzles and the cleaning elements, or vice versa the structure carrying the nozzles and the cleaning elements can be moved over the panel support.

Preferably the device comprises a series of nozzles for spraying water or water and a cleaning mixture on each side of a 'cover, two rotatable

209836/0121

or reciprocable brush elements and one Series τοη nozzles for «dispensing jets of rinsing water» welohee if necessary an addition to support of drying may have. There may also be a device for directing drying air the aperture be included.

The carrier can be arranged on wheels and between the cleaning device of the device of Moved manually, mechanically, electrically or hydraulically will.

The invention is explained in more detail below using an exemplary embodiment with reference to the accompanying drawing.

In the drawing show x

Pig. 1 is a front view of the device according to the invention,

Fig. 2 is a plan view of the device,

3 shows a side view of a support frame for one of the device according to FIGS. 1 and 2

209836/0121

cleansing blend,
Fig. 4 is a top view of the yard η naoh Pig. 3.

Overt reference to Pig. 1 and 2 are in the housing structure 2 shows which front swing door 3 and rear Sohwenktüren 4 includes. The hinges for the doors 3 and 4 are labeled accordingly old 3a and 4a.

On the bottom of the housing structure 2 are containers 5, 6 to absorb cleaning fluids (for example Water) is provided, these containers being connected to each other through a balancing line 7 and to the inlet of a Pump 8 connected by means of a line 9. This pump 8 is driven by a drive unit (for example an electric motor or a gear) 10 driven. The outlet of the pump 8 is connected to a pipeline 11 shown in broken lines. This conduit 11 is arranged to have a series of opposing, inwardly directed Spray nozzles 12 and upper, downwardly geriohteten nozzles 13 can feed. On vertical shafts 20,21 are rotatable Brushes 22,23 arranged, which are driven by electric motors and gears 24,25 via drive chains 26 and 27.

209836/0121

be practiced. This electric drive device 24, 25 and the drive chains 26, 27 are arranged in watertight containers 28, 29.

The free edges of doors 3 and 4 are at a distance from each other arranged to allow a passage of the panel support, which is described below and »it is provided with scraper brushes 30, 31. These scraper brushes or elements 92, 33 are also arranged above and below the housing 2, the brushes 32 being continuations of the brushes 30, 31. the However, brushes 33 extend from the rear to the front of the housing and serve to return cleaning fluid, which runs off the brushes 22, 23, namely back into the containers 5 »6 via openings provided.

The housing 2 has pins 35 on each side so that it can be pivoted on suitable support bearings of a vehicle, for example a trailer vehicle, stored can be so that it is in a horizontal position during transport from one job to another can be swiveled. Also a connection 36 is provided to the containers 5 and 6 to an additional Connect the supply of cleaning fluid.

Referring to Figs. 2 and 3, the carrier comprises for an aperture to be treated is generally rectangular Frame, which consists of two vertical supports 40, 41, which are connected to one another by an upper panel support rail 42 and a lower rail 43 are connected. The lower rail 43 is provided with shafts 44, 45 for Ground wheels 46 are provided. Adjustable on the vertical supports 40, 41 by means of a clamping device 47 is a Rail 48 arranged to clamp a panel hanging from rail 42. Bayonet slots 49 are provided in this upper rail 42 to releasably receive bolts (not shown) to the upper part to attach a cover X to the sole.

The upper sole 42 has an inverted U-shape Cross-section and is two-way adapting to panels of different widths on the vertical supports 40, 41 connected by means of bolts 50 which pass through one of a large number of spaced apart openings 51, which are provided in this rail 42. The tensioning rail 48 and the lower rail are tubular, each formed in two sections that telescope with an inner rod are engaged, as is the case in Pig. 3 is indicated by dashed lines.

209836/0121

In use, a panel to be treated is, for example a window blind stretched on the support frame, it is attached to the upper rail 42 and to the tensioning rail 48 and its slats provided in close position are. The support frame is then placed between the opposed nozzles 12 and brushes 22, 25 of the housing 2 moves. If desired, rails can be provided be to guide the support frame as it moves. The arrangement of the nozzles 12 and the brushes 2 ?, 23 is so that the diaphragm during its movement with respect to the device initially initially with water and / or Detergent is moistened, then exposed to the rotary brushes, which are also exposed to water and / or detergent are sprayed by the nozzles 13 and then exposed to a rinsing jet. The brushes 30, 31, 32 and 33 prevent the jet from exiting the housing 2.

It can be seen that such cleaning is complete and a relatively short time compared to cleaning using conventional methods.

It should be emphasized that means may be provided to prevent drainage of the liquid, they to collect, circulate and, if desired, to filter.
