DETAILED DESCRIPTION




The present invention relates to cleaning various surfaces by employing a tacky surface or sheet on a series of rollers. Some known devices for cleaning surfaces, such as floors, utilize a single roll of perforated sheets having a tacky surface. One problem that arises with these devices is the repeated need for tearing or cutting away the tacky sheets once those sheets become soiled. Furthermore, removing the soiled sheets requires that the user's hands come in contact with the dirt and/or other debris attached to the tacky surface. Also, known tacky roll devices can not work effectively on many surfaces, such as thickly piled carpet, grooved wood floors, grout-separated tile floors, mortar-jointed brick floors, etc., because the known tacky roll devices have little, if any ability to penetrate cracks, crevasses, and deeper layers of carpet, etc.





FIG. 1

is a side view of an exemplary embodiment of a rolling cleaning system


100


of the present invention. Rolling cleaning system


100


can include two large internal rollers


105


,


110


for storing and/or dispensing a continuous long sheet


115


having at least one tacky surface. Tacky sheet


115


can be, by way of example only, plastic or paper coated with an acrylic based adhesive with sufficient tack as to be useful in removing dirt and/or debris from a variety of surfaces. The tack can range between any two integer values in the numerical range of 50 to 500 g/25 mm, with a preferred range of tack between 200 to 300 g/25 mm.




Tacky sheet


115


can be rolled across the floor or surface via four contact rollers


120


,


125


,


130


,


135


. These contact rollers can be constructed from, for example, plastic, rubber, foam rubber, and/or metal, etc. A take-up roller


140


can be used to create a space for the introduction of a brush


145


, and/or to remove slack from tacky sheet


115


. Brush


145


can have stiff bristles, which can be constructed from, for example, nylon, plastic, natural fiber, animal hair, and/or metal, etc. The height of brush


145


can be adjusted by raising or lowering handle


150


, which can be attached to shaft


155


, which can connect brush


145


to a housing


170


.




A large handle


160


can be used to push rolling cleaning system


100


across the floor or whatever surface is to be cleaned. Handle


160


can be pivotably, rotatably, and/or swivelably mounted on a pivot or pin


165


, in a manner well known in the art, to allow rolling cleaning system


100


to be pushed from either direction. By allowing rolling cleaning system


100


to be rolled in either direction, tacky sheet


115


can be dispensed or wound on either internal roller


105


,


110


depending upon the direction rolling cleaning system


100


is being pushed or pulled across the floor. Rolling cleaning system


100


can be at least partially surrounded by enclosure


170


, which can be constructed of, for example, plastic and/or metal.




Internal rollers


105


,


110


can be constructed of, for example, plastic and/or metal, and can be rotationally spring-loaded and/or clutched, e.g., akin to a window blind, to maintain tension in tacky sheet


115


and/or to facilitate the retrieval and/or advancement thereof. Tacky sheet


115


can be provided on, for example, one or two rollers sleeves (not shown) that can be placed onto or over one or both of internal rollers


105


,


110


. A roller sleeve can be constructed of, for example, cardboard, plastic, and/or metal. To avoid rotational slippage between the sleeve and the roller, the sleeves could be, for example, wider than the tacky sheet and secured to the roller with end caps, clamps or rubber bands.




After several uses, tacky sheet


115


can be completely wound back onto a roller sleeve and discarded. This can be accomplished by rolling the rolling cleaning system


100


in the same direction until tacky sheet


115


has completely spooled onto one roller sleeve. Also, this can be accomplished by way of a spring loaded auto advance (not shown) that can be manually activated. The auto-advance can be accomplished pushing a button on the handle or the base of the cleaning system that locks the roller with the sleeve that has the unused portion of the tacky sheet, at the same time this button would release the clamping force on the sleeve on this roller, allowing the sleeve to slip and rotate or slip around the roller (much like a roll of paper towels on a fixed post), as the spring forces in the opposing roller advances the tacky sheet forward and onto the unlocked roller. Further, advancing the adhesive sheet onto the roller sleeve can be accomplished by using an electric motor (not shown). The motor could be attached to one of the roller, preferable the roller without the unused reserve portion of tacky sheet. Again by pushing a button the roller with the tacky sheet would be locked, the clamp that holds the sleeve onto this roller would be released, allowing the sleeve to rotate or slip about the roller. The motor on the opposing roller would then turn this roller and advance the tacky sheet forward and onto the motorized roller. The roller sleeve could advance when the user, for example, pushes a button, turns a knob, and/or squeezes a lever, etc. The electric motor can receive power by either plugging the rolling cleaning system


100


into a power outlet, or by charging a battery to be used by the rolling cleaning system


100


.





FIG. 2

is a side view of an exemplary selection of surfaces that can be cleaned using certain embodiments of the present invention. Surface


200


represents a very smooth and/or flat surface, such as tightly-joined hardwood or marble flooring, certain types of vinyl flooring, smoothly painted drywall, or even smooth concrete. Such surfaces would most likely not require the brush


145


illustrated in FIG.


1


.




Surface


210


represents a much rougher surface, such as worn concrete, black top, or a heavily textured fabric. Such surfaces would likely be cleaned more effectively with the brush illustrated in

FIG. 1

in the down position.




Surface


220


represents a grouted tile or brick flooring surface, or a grooved fabric such as corduroy, that would benefit from use of the brush to removed dirt and debris from the grooves or grout lines.




Surface


230


represents a carpeted or heavily napped surface that would also be cleaned more effectively with the brush in

FIG. 1

in the down position. While these examples illustrate a wide range of surfaces, other surfaces may also be cleaned with the present invention, including, for example, any or nearly any type of flooring, wall, and/or ceiling surface, and/or any or nearly any type of fabric.




In situations where the fabric is part of a garment or small item of furniture, an embodiment of the present invention could be rather small, perhaps less than a few inches wide. In the case of cleaning floors, an embodiment of the present invention could be twelve or more inches wide. In industrial applications, an embodiment of the present invention can be several feet wide. For use outdoors, such as on concrete, asphalt, or artificial surfaces, e.g., Astroturf, an embodiment of the present invention can be up to many yards wide.





FIG. 3

is a side view of an exemplary embodiment of a rolling cleaning system


300


of the present invention. Instead of the brush shown in

FIG. 1

, a sponge


305


can be placed between internal rollers


310


,


315


. Shaft


320


can connect sponge


305


to the rest of the assembly and/or to the housing


307


, and can contain a tube


320


that feeds cleaning solution from a reservoir


325


into the sponge


305


. The action of sliding sponge


305


across the floor can draw the cleaning solution down tube


320


. Reservoir


325


can be attached to handle


330


and/or to the housing and can contain a cap


335


that can be removed to add cleaning solution and/or water to reservoir


325


.




Tacky sheet


340


can be coated with a tacky adhesive that is effective when wet, such as, for example, an adhesive selected from a group consisting of: natural rubber in the presence of a plasticizer mixed with a hydrocolloid gum, synthetic rubber in the presence of a plasticizer mixed with a hydrocolloid gum, or polymeric adhesives consisting of co-polymers of 2-amino ethyl ethacrylate, and n-butyl methacrylate.




Another possible adhesive system would include a single blended adhesive with wet and dry properties. One class of materials, for example, could include the blending of certain hydrocolloid gums (e.g., gaur gum, locust bean gum, etc.) with certain pressure sensitive adhesive systems to improve tack of the moistened adhesive. Since these materials have a large capacity for absorbing moisture, they should provide good wet adhesive or tackiness. Possible pressure sensitive adhesives include many synthetic and natural rubbers in the presence of plasticizers, such as, polyisobutylenes, natural rubber, silicone rubbers, acrylonitrile rubbers, polyurathane rubbers, butyl rubber elastomer, etc. Such mixtures can be further enhanced by the introduction of natural and artificial fibrous materials, such as wood cellulose, cotton, or Dacrun. The introduction of these fibrous materials helps to improve the cohesive forces of the adhesive system.





FIG. 4

is a side view of an exemplary embodiment of a rolling cleaning system


400


of the present invention. This embodiment is similar to the exemplary embodiments illustrated in FIG.


1


and

FIG. 3

, except that neither a brush nor a sponge is provided. Instead, in this exemplary embodiment, rolling cleaning system


400


can have a center roller


410


that serves as a means of removing slack in tacky sheet


420


as tacky sheet


420


slides across the surface or floor being cleaned. Such a device could be particularly useful on smooth surfaces. Further, rolling cleaning system


400


could be useful on non-smooth surfaces if rollers


430


,


440


,


450


,


460


are coated and/or constructed from a compressible foam rubber or other substance that would allow tacky sheet


420


to be pushed into crevices of an uneven surface, such as shown in element


210


of FIG.


2


.





FIG. 5

is a side view of an exemplary embodiment of a rolling cleaning system


500


of the present invention. In this embodiment, cleaning device


500


has a set of contact rollers


510


,


520


,


530


,


540


that allows the tacky sheet


550


to be rolled across the surface rather than slid across the surface as in the earlier embodiments. In some embodiments, contact rollers


510


,


520


,


530


, and/or


540


can be rotationally fixed, thereby serving as guides for tacky sheet


550


. In other embodiments, contact rollers


510


,


520


,


530


, and/or


540


can freely rotate. Such a roller action may improve the effectiveness of the tacky surface in its ability to lift dirt and/or debris from a surface. Brushes


560


,


570


,


580


are located between contact rollers


510


,


520


,


530


,


540


to loosen and/or remove debris that is on the surface and/or in cracks or crevices.





FIG. 6

is a side view of an exemplary embodiment of a rolling cleaning system


600


of the present invention. In this embodiment, instead of the brush shown in

FIG. 5

, a sponge


605


is placed between rollers


610


,


615


. The shaft


620


that connects sponge


605


to the rest of the assembly and/or to the housing


607


contains a tube and/or channel (not shown) that feeds and/or wicks cleaning solution from a reservoir


625


into sponge


605


. Alternatively, the action of sliding sponge


605


across the floor can draw the cleaning solution down the tube. Reservoir


625


is attached to the handle


630


and contains a cap


635


that can be removed to add cleaning solution and/or water to the reservoir. In this embodiment, tacky sheet


640


will be coated on at least its cleaning side with a tacky adhesive that is effective when wet, and possibly on the non-cleaning side with a waterproof or water resistant coating.





FIG. 7

is a side view of an exemplary embodiment of a rolling cleaning system


700


of the present invention. Rolling cleaning system


700


is similar in certain respects to rolling cleaning systems


500


and


600


of

FIGS. 5 and 6

respectively, except that rolling cleaning system


700


does not include a brush or a sponge. Rolling cleaning system


700


has a set of contact rollers


710


,


720


,


730


,


740


that can assist in keeping tacky sheet


780


in contact with the surface to be cleaned, and can help with advancing tacky sheet


780


as rolling cleaning system


700


is moved across that surface. Several take-up rollers


750


,


760


,


770


, which can be spring-loaded in the up-down direction (as determined by the operation of system


700


on a floor), can provide a means of removing any slack that arises in tacky sheet


780


.





FIG. 8

is a side view of an exemplary embodiment of a rolling cleaning system


800


of the present invention. In this embodiment, contact rollers


810


,


820




850


, and


860


assist with keeping tacky sheet


830


in contact with the surface to be cleaned. External contact rollers


810


,


820


are smaller than internal contact rollers


850


,


860


, so that rolling cleaning system


800


can reach under counters and other places that would be hard to reach if all four contact rollers were the same size. Also, adjustable brush


840


can be located between internal contact rollers


850


,


860


.





FIG. 9

is a side view of an exemplary embodiment of a rolling cleaning system


900


of the present invention. In this cleaning device, a sponge


905


is placed between the two internal contact rollers


910


,


915


instead of the brush shown in FIG.


8


. Shaft


920


can connect sponge


905


to the rest of rolling cleaning system


900


. Cleaning solution can flow from reservoir


925


into sponge


905


via a fluidly-coupled channel or tube (not shown) in shaft


920


. The action of sliding sponge


905


across the surface to be cleaned can draw the cleaning solution down the tube. Reservoir


925


is attached to handle


930


and contains a cap


935


that can be removed to add cleaning solution or water to reservoir


925


.





FIG. 10

is a side view of an exemplary embodiment of a rolling cleaning system


1000


of the present invention. This embodiment is similar to those described in

FIGS. 8 and 9

. In this embodiment, cleaning device


1000


has smaller external contact rollers


1010


,


1020


on either end, but does not contain a brush or a sponge.




Although the embodiments described in

FIGS. 1 through 10

contain multiple rollers in contact with the surface to be cleaned, fewer rollers are possible, in fact only one roller could be used in the simplest device. Thus, although not every possible combination of rollers, brushes, and sponges is illustrated herein, the general scope of the present invention includes such variations of the embodiments described herein.





FIG. 11

is a side view of an exemplary embodiment of a rolling cleaning system


1100


of the present invention. In this embodiment, the cleaning device


1100


contains a tacky sheet


1105


that can be advanced or dispensed from one of two sheet rollers


1110


,


1115


depending upon the direction in which the device is rolled across the surface. Tacky sheet


1105


can be held in contact with the surface to be cleaned by two external contact rollers


1120


,


1125


. Two brush rollers


1130


,


1135


are also attached to the base of the rolling cleaning device


1100


on either side of a collection pan


1140


. Brush rollers


1130


,


1135


can pick up dirt and/or debris from the surface. That dirt and/or debris can then attach itself to the tacky surface of sheet


1105


. Alternatively, or in combination, brush rollers


1130


,


1135


can drop the dirt and/or debris into collection pan


1140


.




Tacky sheet


1105


can be guided along a flat planar guide


1155


inside device


1100


by two small guide rollers


1145


,


1150


. As tacky sheet


1105


slides across guide


1155


, tacky sheet


1105


can come in contact with a sheet brush


1160


that can remove any large pieces of loosely attached debris, whereby that debris can be deposited on collection pan


1140


.




Device


1100


can have a handle


1165


, as in previous embodiments, which can be flipped about a pivot or pin


1170


to change the direction of the device. As in previously-described embodiments, certain components of device


1100


, such as rollers


1110


,


1115


,


1120


,


1125


,


1130


,


1135


,


1145


, and/or


1150


, tacky sheet


1105


, collection pan


1140


, and/or brush


1160


, can also be at least partially enclosed in a case, chassis, or housing


1175


made from, by way of example only, plastic or metal. External contact rollers


1120


,


1125


, and brush rollers


1130


,


1135


, can be constructed of plastic, rubber, or other suitable material.





FIG. 12

is a side view of an exemplary embodiment of a rolling cleaning system


1200


of the present invention, which is similar in certain respects to the embodiment illustrated in FIG.


11


. In this embodiment, however, device


1200


has two additional external contact rollers


1210


,


1220


instead of two brush rollers. External contact rollers


1210


,


1220


can allow more surface area of tacky sheet


1230


to come in contact with the surface to be cleaned at any given instant.





FIG. 13

is a side view of an exemplary embodiment of a rolling cleaning system


1300


of the present invention. Device


1300


has two external contact rollers


1305


,


1310


that can help move tacky sheet


1315


across the surface to be cleaned. Tacky sheet


1315


can be advanced onto or removed from one of the two larger sheet rollers


1320


,


1325


inside device


1300


, depending on the direction device


1300


is moving across the surface.




When device


1300


is moved in the direction of the arrow shown in

FIG. 13

, friction between tacky sheet


1315


and the surface to be cleaned causes tacky sheet


1315


to move opposite to the direction of the arrow. Friction between tacky sheet


1315


and drive roller


1330


causes drive roller


1330


to rotate in the clockwise direction. By virtue of the contact between drive roller


1330


and driven roller


1335


, driven roller


1335


rotates in the counter-clockwise direction. Since driven roller


1335


is in contact with sheet roller


1320


, this contact causes sheet roller


1320


to rotate in the clockwise direction which has the effect of pulling tacky sheet


1315


onto sheet roller


1320


. As the diameter of sheet roller


1320


increases due to the accumulation of tacky sheet


1315


therearound, driven roller


1335


stays in contact with sheet roller


1320


by pivoting further up into the housing. The continuous tacky sheet can be spooled onto sheet roller


1325


and off of sheet roller


1320


by reversing the direction device


1300


is moving across the floor. This is done by moving handle


1340


to the right and swiveling handle


1340


about a linkage


1345


that causes the drive roller


1330


and driven roller


1335


to pivot about a pivot point


1350


. When this happens the whole process is reversed and tacky sheet


1315


is now wound onto sheet roller


1325


.





FIGS. 14A

, B, and C illustrate the advancement of material from one roller to the other.




In

FIG. 14A

, the rolling cleaning device


1400


is shown with most of the tacky sheet


1440


spooled up and onto the front roller


1420


, with very little tacky sheet spooled onto the rear roller


1430


. The handle


1410


is tilted to the left and the device is pushed across the surface to the right.




In

FIG. 14B

, the rolling cleaning device is shown after the device as been roller predominately to the right, and as a result most of the material has been advanced from the front roller


1420


to the rear roller


1430


. At this point the handle


1410


would be pivoted in the direction of the arrow in FIG.


14


B.





FIG. 14C

now illustrates the rolling cleaning device with handle


1410


tilted to the right and the device ready to be rolled predominately in the opposite direction with what was the rear roller


1430


, now being the front roller, with most of the tacky sheet spooled up and onto it, and with what once was the front roller


1420


, now being the rear roller, with little if any tacky sheet spooled there upon.




Still other advantages and embodiments of the invention will become readily apparent to those skilled in this art from the above-recited detailed description and provided drawings. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature, and not as restrictive.
