Application July 19, 1948, Serial No. 39,457
The present invention relates to so-called household cleaning implements and has more particular reference to a novel and improved cleaning device which lends itself for effective scrubbing and cleaning of flat smooth surfaces such as found on glass door panels, window panes, painted walls, floors, Windshields, glass show cases and so on and so forth It will be seen, as the introductory statement of the invention explains, that I am aware that there are many and varied types and forms of household cleaning devices for general utility purposes and that it is common to provide a rectangular sponge rubber or equivalent block having handle means and that it is also common practice to employ in conjunction therewith a rubber wiper or squeegee to permit the brushing, scrubbing and wiping steps to be satisfactorily attained. In carrying out the principles of the present invention I provide a cleaning device which is the utmost in simplicity of construction in that it is compact and susceptible of ready manufacture, assembling and sale and is susceptible of attaining the wanted ends with certainty and expediency.
More specifically, novelty is predicated on a backing plate provided with a rigidly attached handle, a rubber or equivalent block fastened on the backing plate, and a simple squeegee on the backing plate with edge portions of the rubber wiper strips projecting beyond the adjacent edge portion of the pad or block.
Other objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.
In the drawings:
Figure 1 is a perspective view of a hand-used cleaning device constructed in accordance with the principles of the present invention;
Figure 2 is a longitudinal sectional view taken centrally through the structure seen in Figure 1;
Figure 3 is a fragmentary view showing, somewhat diagrammatically, the structural elements utilized by me;
Figure 4 is a perspective view of the backing plate.
Referring now to the drawings by reference numerals and lead lines, it will be seen that the cleaning pad, which is used for brushing, scrubbing and other similar tasks, is a sponge rubber or equivalent block 6 of general rectangular form. Said pad may, of course, be made of synthetic or plastic stock or may be a common sponge.
The backing plate 1 isof an area considerably less than the area of the pad and is provided with spaced holes 8' to accommodate fasteners, hereinafter referredto. The pad 6 is glued or otherwise fastened to the backing plate I so that the principal marginal edge portions of the pad project beyond corresponding edge portions of said plate. l l
Numeral 9 denotes a hollow handle which has a head H3 riveted or otherwise secured to the central portion of the backing plate. The offset end of the handle is attached to the plate so as to provide for satisfactory leverage and use. Also, the handle is preferably hollow to provide a socket as shown in Figure 2 which may be emplo'yed to take care of an extension handle ll,
seen in dotted lines.
The numerals l2 designate elongated dupli-- cated strips of rubber or equivalent material. These are su-- perposed upon each other and also superim-- posed upon an edge portion of the backing plateand are secured thereto by an elongated cleat orstrip I3 held in place by rivets, screws, or the-: like 14. The strips l2 project beyond the forward edge of the block and function as a squee which constitute flexible wipers.
gee, as is obvious.
Briefly reviewing the subject matter it will; be seen that it is characterized by a block-like compressible pad of sponge rubber or equivalent material suitable for brushing, scrubbing and cleaning purposes, the same being attached to a flat, primarily rectangular backing plate, the backing plate serving as a mount or base for rubber strips, said rubber strips coacting with a retaining cleat in defining a convenient squeegee. The squeegee is in a plane with the backing plate and projects beyond the adjacent forward or outer edge of the pad. The handle 9 may be used in a manner evident from the drawings or it may be employed as a socket for an extension handle II as indicated by the dotted lines. It is at a satisfactory angle in relation to the pad, backing plate and squeegee to permit said parts to be effectively handled.
The cleaning device is compact, complete in all respects, eliminates splashing, dripping and spattering which is so common when an ordinary bristle brush or the like is used for cleaning purposes. The handle is attached at the correct angle for use of either the pad or the squeegee means. The pad and squeegee units will fit in corners without smearing or splashing the surfaces adjoining the surfaces which are, at the time, being cleaned.
The device may be constructed in such sizes as to adapt it for industrial as well as household purposes and requirements. It will be found handy and useful when employed in and around automotive service stations in that it will handily 5 serve in cleaning Windshields, washing cars, and for other chores. In the ofiice it may be used to assist in cleaning and conditioning linoleums and similarly covered floors.
It is thgught that persgns skilled irr theart to t 1 which theinvention relates willjibeeablea-ttolobtaine a clear understanding of the invention after considering the description in connection with tha drawings. Therefore, a more lengthy descrip tion is regarded as unnecessary. 15
