The present invention relates to an apparatus for polishing and cleaning surfaces, and more specifically to a device capable of dispensing a polishing and cleaning composition and wiping the composition onto the surface simultaneously.
Numerous devices have been developed over the years for dispensing a cleaning or polishing solution and simultaneously applying or wiping the solution off of the surface. The majority of these devices take the form of a mechanism that selectively dispenses an amount of a cleaning and/or polishing solution into a solution or fluid applying member when an actuator, such as an actuating button is pressed. The solution is dispensed directly into the solution applying member, e.g., a sponge, so that the solution disperses throughout the solution applying member for application to the surface.
However, on most occasions the cleaning solution is dispensed into the applying member approximately at the center of the applying member, meaning that a significant amount of the solution must be dispensed into the applying member for the solution to disperse to an applying edge or surface of the applying member. On many occasions, the amount of solution required to be dispensed into the applying member sufficiently to wet the applying member to enable the solution to be applied from the member to a surface is greater than the amount of solution that is applied to the surface. This can result in a situation where a large amount of solution that is utilized in wetting the applying member is wasted, as the solution normally evaporates out of the applying member when the device is not in use.
In order to overcome these shortcomings, other types of cleaning devices have been developed which are capable of spraying a desired amount of a cleaning solution onto the surface for further application to the surface by the applying member of the device. One such device is disclosed in U.S. Pat. No. 2,147,769 in which a spraying mechanism is located on the device to dispense a cleaning or polishing solution either through an opening in a polishing member, or in front of one side of the polishing member. In this manner, the amount of the solution dispensed is controlled in a manner such that the entire amount of solution that is dispensed is almost completely applied to the surface, without wasting any significant amount of the cleaning solution.
Other prior art devices have been also developed which incorporate both of the spraying and diffusion of mechanisms for applying the cleaning and/or polishing solution to a specified surface. For example, in U.S. Pat. No. 5,846,011, a bottle is disclosed including a sponge-like applying member disposed at a dispensing end of the bottle. The applying member is selectively connectable with a first fluid conduit leading into the bottle and through which a cleaning solution can be dispensed into the applying member for dispersion through the member and subsequent application to the surface. Alternatively, the dispensing end also includes a spray nozzle disposed adjacent the applying member that can be activated by retracting the dispensing end into the bottle and rotating the dispensing end to place the spray nozzle in fluid communication with a second fluid conduit.
However, these and other prior art devices for dispensing and applying a cleaning or polishing solution onto a surface have certain shortcomings that prevent the solution from being applied to a surface in a manner that allows for quick and easy application of the solution to the surface with a minimum usage of the solution in order to significantly reduce any wasting of the solution. Thus, it is desirable to develop a cleaning and polishing device that allows for the application of a cleaning or polishing solution to a surface in a manner that allows the solution to be easily applied to the surface with a minimum waste or evaporation of the solution. Also, it is desirable to be able to apply the solution and wipe the surface with only one hand, such that the individual can use the other hand to move objects on the surface, avoiding the cleaner getting onto the hands of the individual.
It is a primary object of the present invention to provide a cleaning device including a dispensing mechanism that allows for dispensing of a cleaning or polishing solution from the device either through or to one side of a solution applying member disposed on the device. The dispensing mechanism includes a rotatable valve capable of selectively enabling the solution to be dispensed from the device by the actuation of the mechanism through either a spray nozzle disposed on the device or through the dispersion of the solution through the applying member. The dispensed solution is provided from a solution reservoir or container that is releasably connectable to the device. The container enables the solution to be withdrawn as desired from the container through the use of the dispensing mechanism until the total amount of solution within the container is depleted, at which time the container can be easily disengaged from the device for disposal, and a full replacement container can be secured to the device for continued usage of the device.
According to another aspect of the present invention, the applying member is releasably engageable with a handle for the device such that the applying member can be replaced as it becomes progressively more soiled after a number of uses. The applying member is designed to enable the solution to be quickly and evenly dispersed from the dispensing mechanism through the applying member for even application of the solution to the surface. Further, the applying member can also include a movable outer member attached to the applying member opposite the handle that enhances the ability of the applying member in cleaning and polishing the surface on which the device is utilized.
According to still another aspect of the present invention, the device is provided with a simplified construction allowing for easy construction and assembly of the device, including the selective dispensing mechanism and the disposable solution applying member, to greatly reduce the time and cost associated with manufacturing and assembling the device.
Numerous other aspects, features and advantages of the present invention will be made apparent from the following detailed description taken together with the drawing figures.

An inner end 40 of the housing 42 includes a container engaging member 44 having a sleeve 46 formed therein but directly engages an outlet 48 of the solution container 50. The outlet 48 is releasably engaged within the sleeve 46 in a fluid-tight manner which allows a polishing or cleaning solution 52 held within the container 50 to be dispensed through the outlet 48 into the solution inlet 38. In preferred embodiments, this is accomplished by forming the outlet 48 with an open end directly engageable with the sleeve 46, or by forming a rupturable plenum (not shown) over the outlet 48 that can be punctured by the solution inlet 38 on engagement of the outlet 48 within the sleeve 46, among other suitable mechanisms, such as a one way valve that opens upon engagement with the container 50.
Once the solution 52 has been completely dispensed from the container 50, the outlet 48 is disengaged from the sleeve 46 such that the entire container 50 can be removed from within the container housing 42 for replacement with a full container 50.
The second-way valve 34 is also positioned in fluid communication with the button 26 spaced from the one-way valve 32 and allows for fluid flow from the space between the button 28 and valve 34 through the valve 34. Opposite the button 36, the valve 34 is connected to a flexible conduit 54, formed similarly to conduit 36, that extends towards the forward end 14 of the handle 12. The conduit 54 is engaged opposite the one-way valve 34 with an inlet 56 of a cylindrical housing 58. The housing 58 extends between the sections 18 and 20 of the handle 12 and holds a cylindrical, hollow rotatable valve 60 therein. The rotatable valve 60 is rotatable within the housing 58 by the operation of a handle 62 extending outwardly from the housing 58 and disposed on the exterior of the handle 12 adjacent section 20 that is engaged with the rotatable valve 60.
The inlet 56 disposed on the housing 58 is spaced ninety (90) degrees from each of a first outlet 64 and a second outlet 66 that are disposed on the housing 58 directly opposite one another. The first outlet 64 is connected to a conduit 68, formed of a flexible material similar to the conduits 36 and 54 described previously, that extends from the first valve outlet 64 to a spray nozzle 70 having nozzle openings 71 extending therethrough that is disposed on the exterior of the forward end 14 of the handle 12. The nozzle 70 can have any number of openings 71 and can also be movable to direct the solution 52 where desired. The nozzle 70 may also be adjustable to alter the form of the solution 52 being dispensed from the nozzle 70, such as between one or more streams or a fine mist.
The second outlet 66 is in fluid communication with a conduit 72, formed of a flexible material similar to conduits 36, 54 and 68, described previously, that is connected opposite the second outlet 66 to a fluid dispersion outlet 74. The rotatable valve 60 includes a pair of apertures 75 spaced ninety (90) degrees from one another. When the valve 60 is rotated using the handle 62, the apertures 75 can be moved between the configuration in
The fluid dispersion outlet 74 extends generally downwardly from the handle 12 into a gap 76 formed between the handle 12 and a solution applying member 78. The solution applying member 78 is releasably attachable to the handle 12 and includes an attaching member 80 releasably securable to the handle 12, an absorbent member 82 secured to the attaching member 80, and a solution applying and cleaning member 84 attached to the absorbent member 82 opposite the attaching member 80.
The attaching member 80 can be formed of any suitable and easily releasable mechanism, such as a hook and loop mechanism, or a snap closing, among others. In a preferred embodiment, the attaching member 80 is formed of a generally rigid material, such as a plastic material, and includes an upwardly extending collar 86 secured to, or integrally formed at one end with a base 88, and having a number of inwardly extending tabs 90 spaced from the base 88. The tabs 90 are slidably and releasably engageable within a pair of notches 92 formed adjacent the forward end 14 of each section 18 and 20. The tabs 90 are biased into engagement with the notches 92 by the structure of the attaching member 80, which deflects outwardly when initially engaged with the handle 12 into the contact of the tabs 90 with the handle 12. As the attaching member 80 is moved further along the notches 92, the tabs 90 are then urged into each of the notches 92 due to the resiliency of the material forming the attaching member 80 to secure the tabs 90 within the notches 92, and the solution applying member 78 to the handle 12. The attaching member 80 also allows the solution applying member 78 to be removed from the forward end 14 of the handle 12 by urging the attaching member 80 away from the notches 92 in order to overcome the bias urging the tabs 90 into the notches 92 and slide the tabs 90 out of the aligned notches 92.
The base 88 is also formed with a rearwardly extending flange 94 that, when the attaching member 80 is engaged with the forward end 14 of the handle 12, is positioned immediately rearwardly of the forward end 14 to function as an additional securing mechanism for the attaching member 80. Furthermore, the base 88 also includes a central opening 96 that forms the gap 76 between the fluid dispersion outlet 74 and the solution applying member 78 when the attaching member 80 is engaged with the forward end 14 of the handle 12.
The absorbent member 82 secured to the attaching member 80 can be formed of any suitable, fluid-absorbent material, and preferably an open cell sponge material, such as various natural and synthetic sponge materials, including, but not limited to, cellulosic sponge material and polyurethane open celled foamed material. The material forming the absorbent member 82 is capable of retaining the solution 52 dispensed from the container 50 through the device 10 and applying the solution 52 to a surface (not shown) to be polished or cleaned utilizing the solution 52. The absorbent member 82 can be utilized alone, or in conjunction with a separate cleaning member 84 releasably attachable to a lower surface 85 of the absorbent member 82 opposite the attaching member 80. The cleaning member 84 is formed of a cloth-like material, such as a non-woven cloth, including, but not limited to, composite non-woven cloths formed of cellulosic fibers, rayon fibers, polypropylene fibers and polyester fibers, that is capable of absorbing the solution 52 dispensed from the container 50, and also capable of picking up dust, dirt or other debris on the surface on which the device 10 is being utilized. The cleaning member 84 is releasably securable to the absorbent member 82 by any suitable means, such as by a low-tack adhesive, or a hook and loop fastener, among others.

When utilizing the device 10 to clean and polish a surface, initially the container 50 including the solution 52 is engaged within the container housing 42 to provide a supply of the solution 52 to the device 10. Depending upon the particular mode of operation desired for the device 10, the valve 60 is rotated within the housing 58 to align the valve apertures 75 with the inlet 56 and either the first outlet 64 for dispensing the solution 52 through the openings 71 in nozzle 70 in front of the solution applying member 78, or with the second outlet 66 for dispensing the solution 52 onto the absorbent member 82. The button 26 is then initially depressed to create a vacuum within the button 26, and subsequently released to draw an amount of the solution 52 from the container 50 through the conduit 36 and one-way valve 32 into the button 26. A subsequent depressing of the button 26 urges the solution 52 contained in the button 26 through the one-way valve 34 and conduit 54 to the housing 58, while also drawing additional solution from the container 50 into the button 26. Depending on the position of the valve 60 within the housing 58, the solution 52 flows either to the nozzle 70 or to the dispersion outlet 74 for the desired manner of application of the solution 52 to the surface.
