Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved squeegee with a pump supplied sponge embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The present invention, the squeegee with a pump supplied sponge 10, is comprised of a plurality of components. Such components in their broadest context include a handle 12, a pump 14, an extension rod 18 and a cleaning head 20. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.
More specifically, the handle 12 is fabricated of sturdy lightweight plastic. It is formed in a cylindrical configuration with a flat inboard end 24 and a flat outboard end 26. The handle has an inboard region 28, an outboard region 30, an upper surface 32 and a lower surface 34. The cylindrical configuration of the handle provides a comfortable gripping surface for the user. Note FIGS. 2 and 3.
The handle has a generally rectangular shaped projection 38 which extends upwardly from its upper surface adjacent to the inboard end. The projection has a generally semicircular shaped bore 40 extending therein. The bore enables the user to comfortably position his thumb within its interior. The contoured design of the bore and projection enables the user to comfortably activate the trigger when pumping is required. Note FIGS. 1 and 6.
A pump 14 is positioned within the hollow interior of the handle below the bore. The pump is shaped in a generally cylindrical configuration with apertures 42, 44 extending through its lower extent at diametrically opposing sides. The apertures in the pump include one-way valves positioned therein. The one-way valves only permit the flow of fluid in an inboard direction. Note FIGS. 4 and 5.
The uppermost extent of the pump has a cover 46 positioned on it. The cover has an aperture 48 extending through its center point. A planar circular disc shaped plunger 50 is positioned within the cylindrical pump. A shaft 52 is affixed to the plunger and extends upwardly and through the aperture in the cover of the pump. The uppermost extent of the shaft includes a planar circular shaped trigger 54. The shaft and trigger are positioned in the cylindrically shaped bore. A resilient tension spring 58 being formed of looped metal wire positioned around the shaft below the trigger. The trigger is adapted to be depressed by the user. The resilient spring forces the trigger back to its original position when released. Note FIGS. 4, 5 and 6.
The user activates the pump by depressing the trigger thereby forcing the plunger downward. This action causes movement of fluid from the pump to the extension shaft of the apparatus. This action also forces the valve between the reservoir and the pump to be forced shut. When the user releases the trigger, the suction causes the movement of fluid from the reservoir into the pump. This action also causes the valve between the pump and extension rod to be forced shut. Note FIGS. 4 and 5.
The upper surface of the outboard of portion of the handle includes a small cylindrically shaped collar 60 with a plurality of external screw threads. A fill cap 62 is coupled to the collar. The hollow interior of the outboard region of the handle is formed as a generally cylindrical shaped reservoir 64. The reservoir is adapted to retain cleaning fluid in the operative orientation. The fill cap is easily removed when refilling of the reservoir is required. In an alternative embodiment of the apparatus the handle is fabricated of clear plastic so the user can easily determine the cleaning fluid level at any point in time. Note FIGS. 1, 4 and 5.
The reservoir communicates with the pump by means of a cylindrical one-way shaped valve 66. The valve is positioned in an aperture of the pump. The valve allows one way flow of cleaning fluid into the pump when the trigger is released by the user. The diametrically opposing side of the pump has a second one-way valve 68 adapted to permit the flow of cleaning fluid from the pump to the inboard region of the handle. The configuration of the pump permits the user to easily perform the alternating compression and suction strokes. Note FIGS. 1 and 6.
The inboard end of the handle has a hollow cylindrical shaped member 72 extending perpendicular therefrom. The member has coupling means 74 at its free end. An extension rod 18 is formed in a hollow cylindrical configuration with two open ends. A first end 76 includes a coupling means and adapted to be coupled to the cylindrical member on the inboard end of the handle. The sturdy construction of the extension rod permits the user to apply significant force to the apparatus when cleaning a subject surface. Note FIGS. 1-3.
A cleaning head 20 includes a cylindrically shaped plug 78 which is adapted to be positioned securely within the extension rod. Note FIG. 6. The plug has three axially positioned apertures 80 extending therethrough. The plug creates a virtually airtight seal within the extension rod. Three rigid hoses 82, 84 are formed in a hollow cylindrical configuration. A first and second hose 82 are formed in an generally L-shaped orientation and positioned in two of the apertures in the plug. A third hose is formed in a linear configuration and positioned between the first and second hoses. When the user activates the pump cleaning fluid is forced through the cylindrical member and extension rod. The fluid is then forced through the apertures in the plug and into the hoses. Note FIGS. 4 and 6.
A holder 86 is fabricated of plastic and formed in a generally rectangular configuration with a hollow interior. The holder 86 has slots 90, 92 in two opposing ends. The hoses are positioned in the hollow interior of the holder. A rubber squeegee 94 is formed in curved planar rectangular configuration. The squeegee is positioned in a rectangular slot of the apparatus. The squeegee is fabricated of sturdy weather-resistant rubber to enhance its strength and durability. The squeegee enables the user to remove dirt and fluid from the subject after the sponge has been applied. The squeegee is particularly effective when used on glass surfaces. Note FIGS. 1, 3 and 6.
A sponge 96 is formed in a rectangular configuration and includes a small projection 98 which extends from one of its ends. The projection of the sponge is positioned in the second slot adjacent to the free ends of the hoses. The hoses have a slight curve at their free ends to direct fluid flow into the sponge. When the pump is activated by the user the fluid ultimately is directed into the sponge. When the sponge is treated with the fluid the user applies the sponge to the subject surface. The abrasive properties of the sponge, coupled with the chemical properties of the cleaning fluid, permit the user to easily clean a wide variety of subject surfaces, particularly glass. The squeegee is used to remove any remaining excess fluid. Note FIGS. 1 and 6.
The squeegee with a pump supplied sponge is a hand tool with a rubber blade, commonly called a squeegee. It is used like a windshield wiper to clean a variety of surfaces, particularly glass, after cleaning fluid has been applied with the sponge of the apparatus.
While hand squeegees are readily available, this unit is distinguished from the others because it has its own supply of cleaning liquid. The cleaning fluid is retained within the handle mounted reservoir of the apparatus. The handle is made of plastic which can be clear to check the fluid level. A trigger protrudes from the apparatus to pump the liquid into the sponge on the cleaning head of the apparatus. The pump is a spring loaded cylinder with valves which draw the fluid in when the compression spring pushes the shaft upward. A trigger on the handle forces the cleaning liquid through a plurality of rigid tubes and into the sponge. The squeegee can be made in various sizes, one of which may be eight inches wide, with a twenty two inch long handle.
After the sponge is filled by virtue of the pumping action, the glass is wiped with the sponge to remove dirt. The squeegee is then used to scrape the liquid from the glass in the usual manner and with the usual efficiency.
Different size reservoirs are available. One size holds eighteen ounces of fluid. A larger size has a capacity of twenty six ounces. This device could also be made in the form of a pistol.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
