2 Claims. (Cl. 134-200) This invention relates to pressure spray washing equipment and more particularly to a shield for the washing and cleaning of Venetian blinds and similar articles.

It is an object of the present invention to provide a pressure spray enclosure which provides means for enclosing an articles to be washed and which includes access means for permitting the handling of the article contained therein.

It is another object of the present invention to provide an enclosure of the above type wherein a fiuiddrain is also associated with the interior of the closure to facilitate the removal of excess cleaning and drying fluids.

Other objects of the invention are to provide a pressure spray booth for the washing and drying of Venetian blinds and other articles bearing the above objects in mind which is of simple construction, has a minimum number of parts, is inexpensive to manufacture and efficient in operation.

For other objects and for a better understanding of the invention, reference may be *had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure 1 is a perspective view of a preferred embodiment of the present invention shown in operative use with a window mounted Venetian blind;

I Figure 2 is an enlarged transverse cross sectional view taken along line 22 of Figure 1;

Figure 3 is an enlarged fragmentary cross sectional view taken along line 33 of Figure 1;

Figure 4 is an enlarged perspective view of a support bracket shown in Figure 1; and

Figure 5 is a perspective view of a modified form of the present invention.

Referring now more in detail to the drawing, and more particularly to Figures 1 to 4 thereof, a pressure spray booth made in accordance with a preferred form of the present invention is shown to be in the form of a cubicle type housing of a type that is adapted to enclose a Venetian blind 11 that is operatively supported within a window frame 12. This housing is closed on all sides and is provided with an open top 13, whereby the housing may he slipped upwardly about the blind 11 and secured to the top thereof by means of pivotally mounted hooks 14. As is more clearly shown in Figure 2, these hooks 14 are rotatably supported upon longitudinally extending support rods 15 that are fastened to the upper sides of the housing. The front side of the housing is provided with a vertically extending slide fastener 16 that may be used, if necessary, to gain access to the interior of the housing.

ice

bands 18 at their inner end and which are secured at their outer end to the front side, such as by'rivets 19. An auxiliary access sleeve 21 is provided adjacent to the lower corner of the housing and is provided with a similar elastic band 22 at its inner end. The bottom wall 24 is inclined downwardly and is provided with an outlet hose 25.

In using this cubicle, it is slipped upwardly over the mounted blind and the hooks 14 are received within slots 28 at each end of a pair of curved metal bars 27 that are supported directly on top of the blind. A spray nozzle, or similar apparatus, is inserted through the auxiliary access sleeve 21 so that it may be grasped by the hands that are extended through the pair of sleeves 17, whereby the blind 11 may be thoroughly washed in a somewhat conventional manner, except that all fluids are confined within the cubicle and may be removed through the drain hose 25. The cubicle is supported upon the blind so that the back wall thereof is closer to the blind than the front wall, whereby the back wall tends to provide a continuous rebounding pressure spray which further enhances the cleaning operation.

Referring now to Figure 5 of the drawing, a cubicle in the form of an enclosure 30, made in accordance with a modified form of the present invention is shown to be provided with an elastic band 31 that is adapted to encircle a human head, so as to confine the hair within the enclosure. A pair of sleeves 32 extend inwardly to pro vide access to the interior of the enclosure, through which an operators hands may be extended so that the hair may be washed. A drain hose 36 adjacent to the bottom end of the enclosure permits excess fluid to be drawn off.

It will be recognized that the principles of this invention may be applied to various cleaning operations. As

such, the parts may be preferably constructed of any flexible type material, such as transparent plastic, whereby the cleaning operation may be observed at all times. The access sleeves may also be used to receive and discharge a pressurized flow of air to facilitate the drying operation, and the drain hose may merely extend to a sink drain or may be provided with vacuum pressure to positively draw off the cleaning fluid.

Therefore, while various changes may be made in the detail construction, it will be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

What I claim as new and desire to protect by Letters Patent of the United States is:

l. A pressure spray booth comprising, an open ended flexible transparent enclosure collapsible upon all sides thereof, flexible means for removably securing said enclosure by its open end about an article to be cleaned and to an independent support carried by said article, access means carried by said enclosure communicating with the interior thereof comprising a pair of adjacent spaced apart sleeves extending into the interior of said enclosure through which the arms of the operator can 'be extended to the interior of the enclosure, said sleeves being open at their outer ends and closed at their inner ends by yieldable elastic means when extended over the arms of the operator, further flexible water tight access means in the enclosure wall for releasably receiving a spray nozzle in a location thereon so as to be reached by the operator when the arms are extended into the interior of the enclosure through the sleeves and a fluid drain carried by said enclosure for carrying fluid outwardly from the interior of said enclosure, said fluid drain comprising an outlet adjacent to a lower portion of said enclosure.

2. The combination according to claim 1, wherein said removably flexible securing means includes support hooks carried by the enclosure Wall in the opening thereof and a pair of rigid arcuate bars adapted to be supported upon the top of a Venetian blind supported at the top of a window opening and adapted to overlie longi- 4 sides thereof and having slots adapted to removably receive said hooks.
