This application is related to provisional application Ser. No. 60/782,461, filed on Mar. 15, 2006, and entitled “Method and Apparatus for Applying a Floor Product Solution”, which is herein incorporated by reference.
The present invention relates generally to a method and apparatus for applying a liquid product to a floor. In particular, the invention relates to applying a thickened liquid floor product to a floor.
A variety of liquid products are applied onto the surface of a floor to provide proper care. One such product is a stripper that removes floor finish already applied on the floor. Such strippers typically have a low viscosity, e.g. 200 cps or less. Traditional floor strippers are applied and distributed on the floor surface with a conventional string mop and bucket. While effective, the use of mops in the stripping process has several undesirable outcomes, including placing stripper on surfaces perpendicular to the floor, such as walls and baseboards, and extensive clean-up time required to rinse residual stripper solution from the mop.
Additional issues associated with applying stripper onto a floor using a conventional mop occur when applying thickened strippers. Thickened strippers typically have a viscosity between approximately 300 and approximately 1,000 cps and provide advantages over lower viscosity strippers. Because such thickened stripper products do not readily flow, they are not as easily applied using a string mop. For instance, mop lines are easily visible on the floor and the areas where the stripper is more thinly applied do not strip as effectively. Additionally, because thickened strippers are typically more viscous, it is difficult to get the thickened stripper into tight spaces such as corners and edges using a conventional mop, without getting the thickened stripper on vertical surfaces such as baseboards and walls. Applying thickened strippers with a string mop is also an ergonomic challenge. If a string mop is utilized, the mop becomes quite heavy and can weigh up to 20 pounds when wet. Further, there is a significant amount of “mop drag” and the mop is only able to dispense approximately three pounds of the thickened stripper before it is necessary to dip the string mop back into the bucket to obtain more thickened stripper.
There is thus a need in the art for an applicator that overcomes the extensive clean-up time, undesirable placement of stripper, ergonomic issues, and leveling problems associated with string mop applications.
In a first embodiment, an applicator tool for applying a liquid onto a surface of a floor includes an applicator and a handle connected to the applicator. The applicator includes a housing having a bottom surface and a plurality of sidewalls. The bottom surface is connected to the sidewalls to define a reservoir. The bottom surface has at least one opening in fluid for substantially continuously dispensing the liquid.
In another embodiment, a method of dispensing a liquid product onto a surface includes filling a reservoir of an applicator with liquid product, moving the applicator across the surface, and continuously dispensing the liquid product from the applicator. The applicator has an open top surface, a bottom surface, and at least one opening formed in the bottom surface. The liquid product is dispensed through the opening in the bottom surface of the applicator.
In another embodiment, the invention is an applicator tool for applying a liquid product onto a floor. The applicator tool includes an applicator, a handle connectable to the applicator, and a spreading mechanism. The applicator has a substantially planar bottom surface that includes at least one opening for continuously dispensing the liquid product. The spreading mechanism is formed of a flexible material connected to the bottom surface of the applicator and spaces the bottom surface of the applicator from the floor.
Handle 12 has first end 20 for gripping and second end 22 pivotally connected to applicator 14 at pivot joint 24. Handle 12 may have a bend 12a between first and second ends 20 and 22 to allow a more ergonomically correct grip of tool 10. Handle 12 may be separate or an integral portion of tool 10 and may be formed by any means known in the art. In an exemplary embodiment, handle 12 has approximately 360 degrees of movement for easier application of liquid product 16.
Applicator 14 generally includes housing 26 that forms reservoir 28 having an open top 30. In operation, when applicator tool 10 is to be used, tool 10 is lifted at first end 20 of handle 12 to submerge applicator 14 into bucket 18. When applicator 14 is submerged within bucket 18, liquid product 16 housed in bucket 18 is allowed to enter reservoir 28 of applicator 14 through open top 30. Housing 26 may be formed of materials including, but not limited to: a polymer or stainless steel. In an exemplary embodiment, housing 26 is approximately 12 inches by approximately 8.5 inches by approximately 2.5 inches. However, applicator 14 may vary in size as long as it is adapted and configured to fit into the standard size mop bucket 18.
Bottom wall 32a of housing 26 includes top surface 34, bottom surface 36 (shown in
First and second mounting members 40a and 40b are attached to top surface 34 of bottom wall 32a and function as a fastening mechanism to attach second end 22 of handle 12 to applicator 14. First and second mounting members 40a and 40b are positioned substantially equidistant from each of walls 32b-32e to ensure the widest range of motion for handle 12. To attach handle 12 to first and second mounting members 40a and 40b, second end 22 of handle 12 engages sleeve 42, which is attached to connector 44. Connector 44 is pivotally attached to first and second mounting members 40a and 40b such that handle 12 can move toward front wall 32b and rear wall 32c. In addition, handle 12 is rotatably secured within sleeve 42, allowing handle 12 to pivot towards first side wall 32d and second side wall 32e and rotate with respect to housing 26. This connection allows for approximately 360 degrees of movement, although it is understood that other suitable connections may also be utilized. As previously mentioned, rear wall 32c includes notch 32f sized and positioned such that when tool 10 is lifted, handle 12 settles in notch 32f in rear wall 32c. First and second mounting members 40a and 40b are offset such that when tool 10 is lifted straight upward, tool 10 tilts so that handle 12 rests in notch 32f of rear wall 32c. This feature is important as it “locks” handle 12 in place and prevents liquid product 16 from spilling over walls 32b-32e of tool 10.
Liquid product 16 (shown in
In operation, protrusions 48 contact the floor such that bottom wall 32a of housing 26 is spaced from the floor by protrusions 48. Projections 48 are raised a height H from the floor. Height H determines the thickness that liquid product 16 is applied to the floor as applicator 14 is moved back and forth along the floor. However, height H may vary depending upon the actual stripper, the type of liquid product being used, or roughness of the surface being treated. Height H may also be varied by changing the thickness, height, or flexibility of projections 48.
In operation, protrusions 50 contact the floor such that bottom wall 32a of housing 26 is spaced from the floor by protrusions 50. The next surface up vertically from the floor is elongate raised member 54. Elongate raised member 54 is raised a height H1 from the floor. Height H1 determines the thickness that liquid product 16 is applied to the floor as applicator 14 is moved back and forth along the floor. In an exemplary embodiment, height H1 is between approximately ⅛ inches and approximately ¼ inches for a thickened stripper having a viscosity of between approximately 300 cps and approximately 1,000 cps. However, height H1 may vary depending upon the actual stripper, the type of liquid product being used, or roughness of the surface being treated.
In operation, projections 68 bend and maintain bottom wall 32a of applicator 14 from the floor as applicator 14 is moved along the floor. The thickness of liquid product 16 being dispensed onto the floor is determined by the distance, or height H3, from base 66 to the support provided by projections 68. Height H3 may be varied by changing the thickness, height, or flexibility of projections 68.
Referring back to
Each spreading mechanism 46, 46a, 46b, or 46c provides a more even distribution of liquid product 16, especially a thickened floor stripper, onto the floor. In all embodiments of spreading mechanism 46, 46a, 46b, and 46c, liquid product 16 is dispensed through holes 38. The spreading and leveling action is slightly different with respect to each spreading mechanism 46, 46a, 46b, or 46c. When the first embodiment of spreading mechanism 46 is used, applicator 14 is held off of the floor by protrusions 46 and the thickness of liquid product 16 being applied is controlled by the difference in height H between protrusions 46 and the floor. With respect to the second embodiment of the spreading mechanism 46a, when applicator 14 is placed on the floor, applicator 14 is held off of the floor by protrusions 50 and the thickness of liquid product 16 being applied is controlled by the difference in height H1 between protrusions 50 and elongate raised member 54. With respect to the third embodiment of spreading mechanism 46b, when applicator 14 is placed on the floor, projections 60 and 62 bend and the thickness of liquid product 16 being dispensed will be controlled by the difference in height H2 between projections 60 and 62 and the floor. With respect to the fourth embodiment of spreading mechanism 46c, when applicator 14 is placed on the floor, projections 68 bend over, as shown in
Spreading mechanisms 46, 46a, 46b, or 46c are textile free and utilize spreaders that are also textile free, although a textile such as a microfiber may also be used. Projections 48 of the first embodiment of spreading mechanism 46; projections 50 and elongate raised member 54 of the second embodiment of spreading mechanism 46a; base 56 and central protrusions 60 and finger-like projections 62 of the third embodiment of spreading mechanism 46b; and base 66 and projections 68 of the fourth embodiment of spreading mechanism 46c are all textile free (or a microfiber) and substantially non-absorbent. They are typically made from a suitable polymer as previously discussed. Elongate raised member 54, projections/protrusions 48, 50, 60, 62, and 68 are relatively soft, lightweight, and easy to clean.
Spreading mechanism 46, 46a, 46b, or 46c may also be used without a reservoir 28. In such instances, liquid product 16 may be placed on the floor. In such instances, liquid product 16 may be placed on the floor by any means known in the art, including, but not limited to: pouring liquid product 16 from a bottle or throwing liquid product 16 from bucket 18. Alternatively, there may not be any holes or openings at the bottom of reservoir 28. In such instances, reservoir 28 may be emptied by tipping applicator 14 to dispense liquid product 16 out of open top 30 of reservoir 28. It is also understood that instead of filling reservoir 28 by immersing it in bucket 18, reservoir 28 may be filled by other methods, such as by pouring liquid product 16 from a bottle or container into reservoir 28 through an appropriate opening. Also, reservoir 28 may be a snap-on with the snap-on being brought to a location where it is filled and then brought back and placed on handle 12.
A first mounting member 116a is connected to first dividing member 110a and a second mounting member 116b is connected to second dividing member 110b. Mounting members 116a and 116b are mirror images of each other. For simplicity, only first mounting member 116a will be described in more detail, although it should be understood that second mounting member 116b has the same features as first mounting member 116a. Although first mounting member 116a has the same features as first mounting member 116a. Although first mounting member 116a is depicted as being a two-piece injected molded part, any suitable construction may be utilized. First mounting member 116 generally includes a U-shaped protrusion 118a and a bore 120a. U-shaped protrusion 118a is matched to a U-shaped opening to connect the two injection molded parts of second mounting member 116b. Again, the construction may be any suitable construction. A yoke member 122 has a pin 124 (shown in
Bottom wall 104a of applicator 102 includes holes 134 that allow reservoir 108 to be in communication with the floor. Similar to the first embodiment of applicator 14, holes 134 are generally equally spaced from one another and extend through bottom wall 104a. In an exemplary embodiment, holes 134 are approximately 0.25 inches in diameter and are spaced approximately 1 inch from one another. The size and number of holes 134 may vary depending upon the viscosity of liquid product 16 in reservoir 108 and the rate at which it is desired to dispense liquid product 16. Also, although
The second embodiment of applicator 102 may use first, second, third, or fourth embodiments of spreading mechanism 46, 46a, 46b, or 46c (shown and described in
The applicator tool generally includes an applicator and a handle rotatably connectable to the applicator. The applicator has a spreading mechanism that is beneficial in more evenly spreading a liquid product on the floor by reducing the surface area of the applicator that is in contact with the floor, thus reducing surface drag during application. The spreading mechanism of the applicator is particularly useful for evenly spreading a thickened liquid product, i.e., having a viscosity of from approximately 300 to approximately 1,000 cps. The spreading mechanism provides an even distribution of the liquid product on the floor. The spreading mechanism may be either permanently or removably attached to a bottom surface of the applicator. Projections space the bottom surface of the applicator from the floor and spreads the liquid product. Because the applicator is textile free, it will not absorb any of the liquid product, allowing the applicator to spread the liquid product across the floor more evenly. The applicator may also be constructed of natural and synthetic polymers or of a textile-based product such as a microfiber.
Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
