Description




BACKGROUND AND DISCUSSION OF THE INVENTION




The present invention relates to a floor mat. More specifically, the invention provides a floor mat that includes a cleanable portion. The floor mat may also include a water dissipation component, a water absorbing component, a cushioning component, customized graphics, a transparent cleanable portion, a tacky surface on the cleanable portion, an antibacterial composition, an antifungal composition, and a fragrance. The cleanable portion may be erodible and may include a plurality of cleanable reusable layers. If a tacky surface is included in the floor mat, an anti-slip feature may be associated with the tacky surface to help prevent slipping on a possibly wet tacky surface. Additionally, a sensor system may be included in the floor mat to assist a user in identifying when the floor mat may require cleaning.




Floor mats are known for cleaning the soles of a person's shoes who is about to enter a particular area or room. One problem with floor mats in general is how to keep the floor mat sufficiently clean such that it may perform its function of cleaning the person's shoes when, by its very nature, it is purposefully dirtied when performing its function.




Known floor mats may be comprised of a single, unitary piece of material. Whereas these single structure floor mats may be kept clean by, for example, washing the floor mat, it may be required that the entire floor mat be removed from its location for washing and thus, the floor mat is not available where desired while the entire mat is being cleaned. Alternatively, even if the mat can be cleaned in-place, which may not be a possibility if it is located in, for example, a carpeted area, it may be inconvenient to clean the mat in-place.




U.S. Pat. No. 3,785,102 to Amos discloses a throw-away pad comprising a plurality of stacked disposable sheets where, when a particular sheet is dirtied, the dirty sheet is removed and disposed of. The next sheet that is exposed after the dirty sheet is discarded is clean and thus, a clean surface is again available. However, there may be problems with comprising the floor mat of disposable sheets. Disposing of each dirty sheet may be uneconomical since each sheet is discarded after it becomes dirty. Additionally, after some finite number of sheets are disposed of, no sheets will remain and thus no effective cleaning surface is available.




U.S. Pat. No. 3,785,102 to Amos also discloses that an adhesive can be provided on each sheet's top surface to improve its ability to remove dirt from a person's shoes. However, again, these sheets are not cleanable and therefore are not reusable.




U.S. Pat. No. 3,717,897 to Amos et al. discloses a pad for cleaning shoes and wheels. The pad includes a thin water-washable adhesive covering its upper surface for removing dirt from shoes and wheels. Whereas the '897 patent discloses a pad with a water-washable adhesive upper surface, the pad is not known for use in domestic or office-type applications. As stated in the '897 patent, the pad is placed at an entrance doorway leading into a clean room.




Tacky floor mats are by far more popular for utilization in indoor environments that are far removed from exterior outside entrances, such as for clean rooms that are well-within the interior of the building in which they are used, e.g., hospital rooms, computer chip manufacturing spaces, and gymnasiums. Thus, tacky floor mats are not known for use in areas that are adjacent to entrances that lead from the outdoor environment for cleaning the soles of a person's shoes prior to entry into the interior of a building, such as for example in an entry foyer or on an outdoor porch.




Tacky floor mats are not known for use in domestic or office-type applications, e.g., home or business office use, because of several known deficiencies. One of these deficiencies is that their tacky surface will not be as effective if it becomes wet. Therefore, if the tacky surface floor mat was utilized in an outdoor environment, such as the outdoor porch mentioned above, or in an indoor environment that is adjacent to or near an outdoor entrance, such as an entry foyer of a home or business, for cleaning a person's shoes prior to further entering the home or business, the mat is likely to become wet and therefore not effective. The mat could become wet from, for example, the moisture in the atmosphere or from moisture carried on the soles of the person's shoes who steps on the mat. Additionally, if the tacky surface becomes wet it may become slippery and thus cause a hazard for the person who steps on it.




Additional deficiencies with using known tacky floor mats for home or office-type applications as discussed above is their likelihood of becoming trip hazards and their lack of aesthetic appeal. In the '897 patent, because the pad is designed for use in clean room environments, it is adhesively adhered to the passageway floor in front of the entrance doorway. This may be satisfactory for retaining the mat in-place in clean room-type of applications, however, if it was attempted to use the '897 pad on a carpeted floor, the pad would not properly adhere to the carpet and thus a trip hazard would be present. This could result in significant liability issues. The '897 pad does not have sufficient mass for it to remain in-place without utilizing an adhesive. Regarding aesthetics, because tacky floor mats are known only for their functional characteristics, and thus for use only in “clean room”-type applications, they are not aesthetically pleasing. Therefore, for at least the above reasons, tacky floor mats are not known for use in home or office-type applications.




Additional drawbacks with known floor mats exist that are directed to issues of customization for a particular purchaser and a lack of additional cleaning properties. A floor mat may be the first object that a visitor to a particular home or business encounters. As such, the owner of the home or business may want to utilize the floor mat to graphically convey an initial greeting or message to the visitor. Whereas floor mats are known that may include a greeting on them, it is not currently known to allow for a particular purchaser to customize the displayed graphic so that the message is tailored to convey a particular message desired by the purchaser. For example, on Halloween the purchaser may want the floor mat to display a “Happy Halloween” message. In another situation, the purchaser may want to greet a particular visitor with a message such as “Hello, Joe”. Currently, it is not known to provide a floor mat where an individual can customize the floor mat to display a particular message that they want to convey and in certain circumstances even change the floor mat's message they want to convey.




An additional problem with known floor mats, as mentioned above, is that they are limited in their ability to clean the soles of a person's shoes. Whereas known floor mats may be capable of removing dirt particles from the shoe's soles, they are not able to disinfect the soles nor provide a scent to the soles to assist in masking any unpleasant odors that may be associated with the shoes.




An additional drawback with known floor mats, even if they are cleanable, is that they do not assist a user in determining when the floor mat may require cleaning. Generally, the owner or custodian of the floor mat does not continuously or regularly monitor the condition of the floor mat with respect to cleanliness. Therefore, the floor mat could require cleaning, and because the owner is not consciously monitoring the condition of the floor mat, there could be a significant period of time before the owner realizes that the floor mat requires cleaning. Therefore, it would be desirable to assist the owner/custodian of the floor mat in determining when the floor mat requires cleaning.




Therefore, it would be desirable to provide an advanced floor mat that could address deficiencies that exist with currently known floor mats. The advanced floor mat of the present invention overcomes deficiencies in the prior art and may include a base portion which incorporates a cleanable portion that is adapted to be removably received within the floor mat. The floor mat may also include features such as a water dissipation capability, a water absorbing capability, a cushioning capability, customized graphics, a transparent portion, a tacky surface on the cleanable portion, an antibacterial composition, an antifungal composition, and a fragrance. The cleanable portion may include the features of being erodible and containing a plurality of cleanable reusable layers. If a tacky surface is included in the floor mat, an anti-slip feature may be associated with the tacky surface to help prevent slipping on a possibly wet tacky surface. Additionally, a sensor system may be included in the floor mat to assist a user in identifying when the floor mat may require cleaning. Other features will be apparent from the detailed description which follows.

DETAILED DESCRIPTION





FIG. 1

illustrates a first embodiment for a floor mat


100


in accordance with the principles of the present invention. As can be seen in

FIG. 1

, floor mat


100


includes a base portion


200


and a cleanable insert portion


300


. As will be further described later in this specification, in this embodiment, cleanable portion


300


is received within base portion


200


and is removable from base portion


200


.





FIG. 2

illustrates an exploded, perspective view of the floor mat of FIG.


1


. As can be seen in

FIG. 2

, base portion


200


is formed as a generally flat, planar member and defines a recess


210


within the top surface of base portion


200


. Base portion


200


provides sufficient weight and mass for supporting cleanable insert portion


300


and maintaining the floor mat's positioning on the surface on which it is placed. Base portion


200


may include, as will be discussed below, a water dissipation capability, a water absorption capability, and a cushioning capability and may be comprised of materials such as polyurethane, polyisoprene and other cross-linked elastomeric materials, such as nylon-6, molded or woven to form a porous structure. Recess


210


can be configured in any of a variety of geometric configurations, however, in the present embodiment, recess


210


is configured in a rectangular shape. Recess


210


has a length L


1


and a width W


1


. The depth of recess


210


is such that it is able to receive within it cleanable insert portion


300


such that when cleanable insert portion


300


is received within recess


210


, the top surface of cleanable insert portion


300


lies generally in the same plane as the top surface of base portion


200


.




The top surface of base portion


200


may be colored with any color depending upon the desires of a particular purchaser, however, it is preferable that a color be utilized that will minimize the visibility of any dirt that is accumulated by base portion


200


. For example, it may be desirable that darker colors be utilized for the top surface of base portion


200


rather than lighter colors. However, again, any particular color may be utilized for base portion


200


, and particularly the top surface of base portion


200


, depending upon the particular desires of an individual. Additionally, the base portion


200


may be either translucent or opaque.




As can be seen in

FIG. 2

, the surface of base portion


200


which defines the bottom of recess


210


may include graphics


220


on that surface. In the illustrated embodiment, the graphics include pictorial representations of flowers and a text message which spells out the word “WELCOME”. The present invention is not limited to any particular graphic within recess


210


and the present invention may include any of a variety of different forms of graphics.




Graphics


220


may be modified, and thus customized, by an individual after the floor mat has been purchased by the owner. The owner may customize the mat at their home or office and, thus, a graphic that may be appropriate for a particular situation may be modified by the individual for display in another situation. For example, the graphic may display a message stating “Happy Halloween” for Halloween and may be modified to display “Happy Holidays” during the winter holiday season. Thus, as can be understood, the graphics are modifiable by a user and thus, may be customized for the particular desires of a particular user.




As stated above, the present invention is not limited to any particular form for graphics


220


. The graphics


220


can be customized by a user to include any of a variety of different colors, pictures, messages, or other representations that the user may want to display. In addition, the visible intensity of a color(s) can be modified. For example, a color that glows at night could be included in graphics


220


for an occasion such as Halloween.




Any of a variety of different types of structures or methods may be practiced in the present invention for modifying graphics


220


of floor mat


100


and the present invention is not limited to any particular methodology or structure for modifying graphics


220


. Additionally, all of the various embodiments contemplated for providing a modifiable graphic display in the floor mat of the present invention can be incorporated in either, or both, of the base portion or the insert portion. For example, the graphics may consist of pre-formed messages or art forms which may be adhered to either the surface which defines the bottom of recess


210


, such as by using an adhesive or fastener assembly, e.g., a hook and loop assembly, or to the underside of insert portion


300


such that, when insert portion


300


is placed within base portion


200


, the graphics would be visible through a transparent insert portion.




Alternatively, a variety of different graphics may be stored within floor mat


100


such that a user is able to selectively uncover a particular graphic for display while the other available graphics remain covered within floor mat


100


. This type of selectability is known in other mediums where selectivity between a variety of different graphics within a common display panel is desired. For example, advertising bulletin boards at sporting events are able to selectively display a first particular message during a first particular period of time and display a second message during a second period of time on the same bulletin board.




A third possible alternative is to provide a modifiable display on the floor mat. The display surface can be associated with either the base portion or the insert portion, e.g., on either the bottom surface of recess


210


or attached to the bottom of insert portion


300


. A display could be included on the front of the floor mat, on the back of the mat such that it is viewable through a transparent portion of the mat, embedded in the mat, attached to the mat, or integrally formed in the mat. For example, the display could be comprised of a small, thin box of graphics that could attach to a tacky portion and/or a base portion or any other component part of the floor mat. However it is associated with the floor mat, a user may design and display their customized graphic and may subsequently modify that graphic such that it is replaced with another graphic. A display surface such as an erasable writing board could be utilized for this purpose.




It is also contemplated that a modifiable electronic display surface could be provided, such as, for example, a liquid crystal display. The display could be connected to a computer and a computer generated image could be displayed on the display. Thus, the image displayed on the display could be modified by generating a different computer image and displaying that computer image on the display. The display could be associated with base portion


200


, such as included within recess


210


, or could be included on a bottom surface, facing upward, of insert portion


300


. Alternatively, the display could be integrally formed with either of the base portion or the insert portion. The modifiable display could utilize a plurality of different graphics that can be displayed in any of a variety of manners on the display. For example, the graphics could be displayed in a generally fixed position on the display or could scroll across the display, with both exemplary methodologies displaying multiple graphics either individually or in combination.




Other alternatives for modifying the graphics


220


of floor mat


100


include using light emitting polymers to create, and thus change, graphics


220


. The light emitting polymers can be either applied to, attached to, or woven into the floor mat. The light emitting polymers may be utilized on any portion of floor mat


100


, for example, on either the base portion or the insert portion, or on any other portion of the different embodiments for the floor mat. Light emitting polymers are known and described in U.S. Pat. Nos. 5,945,502, 5,869,350, and 5,571,626, which are incorporated herein by reference in their entirety.




Other options for a display are to use electronic ink or electric paper. Electric paper is available from Xerox and is described in U.S. Pat. Nos. 5,723,204, 5,604,027, 4,126,854, and 4,143,103, which are incorporated herein by reference in their entirety. Electric paper employs thousands of tiny, electrically charged beads, called Gyricon, each about the width of a human hair, to create pixels. The two-tone beads are embedded inside a liquid-filled plastic sheeting that forms the surface of the paper. Each bead, half-black, half-white, gyrates in response to an electric field. Whether the beads are black- or white-side up determines the image. Because there's no need to refresh the image, and because the screen isn't backlit, electric paper uses only a fraction of the power used by conventional electronic displays. Electromagnetic styluses and printer-like devices can be used for getting images onto the paper.




Electronic ink is available from E Ink Corp., at 45 Spinelli Pl., Cambridge, Mass. 02138. Electronic ink uses a microencapsulated micromechanical display system. Tiny microcapsules are captured between two sheets of plastic to create pixels. Alternatively, the capsules may be sprayed on a surface. The result is a flexible display material. The tiny capsules are transparent and contain a mixture of dark ink and white paint chips. An electric charge is passed through the capsules. Depending on the electrostatic charge, the paint chips float at the top or rest on the bottom of each capsule. When the paint chips float at the top, the surface appears white. When they rest at the bottom, and thus under the ink, the surface appears black. Each of the two states is stable: black or white. A transparent electromagnetic grid laid over the sheet's surface controls the shape of the image. The display may be wirelessly connected to, for example, a computer and thus, the World Wide Web by utilizing, for example, a Motorola paging system. Text on all displays, if multiple displays are used, can be changed at once by a single editor, through a Web page.




Again, a display which could utilize any of the methods discussed above for modifying the display, could be associated with any portion of the floor mat, such as base portion


200


within recess


210


or on a bottom surface, facing upward, of insert portion


300


. Alternatively, the display could be integrally formed with either of the base portion or the insert portion. The display could be utilized in any of the embodiments disclosed herein for the floor mat of the present invention, including a floor mat that includes a tacky surface and a non-tacky floor mat embodiment.




In further describing base portion


200


, as mentioned above, base portion


200


may also include both a water dissipation component and a cushioning component. The water dissipation component provides for transferring moisture from the soles of a person's shoes that is standing on floor mat


100


to reduce the degree of moisture transferred to cleanable insert portion


300


and the cushioning component provides for conforming the floor mat


100


to the shape of the person's soles such that a greater amount of the debris on the person's soles may be removed by floor mat


100


. The present invention is not limited to any particular structure or material for the water dissipation component and the cushioning component. For example, the water dissipation component may be comprised of any of a wide variety of known materials, such as polyamides, vinylics, and polyisoprene. It is desirable, but not required, that the water dissipation component dissipate or move the water and not retain the water. Thus, porous materials, and not hydrophilic materials, are desired. The cushioning component may be comprised of any of a variety of cushioning components to include, for example, foam rubber.





FIG. 2

also further illustrates cleanable insert portion


300


. As can be seen, cleanable insert portion


300


has a geometric shape which is complementary in size and form to the recess


210


that is formed within base portion


200


. As such, cleanable insert portion


300


is able to be received securely within recess


210


. Thus, cleanable insert portion


300


has a length L


2


which is just slightly smaller than the length L


1


of recess


210


. Likewise, cleanable insert portion


300


has a width W


2


which is also just slightly smaller than width W


1


of recess


210


.




On the bottom side


310


of cleanable insert portion


300


, i.e., that surface which contacts the surface which defines the bottom of recess


210


, an attachment mechanism may be provided such that cleanable insert portion


300


may be removably attached to base portion


200


within recess


210


. Any of a variety of different attachment mechanisms may be provided on the bottom surface of cleanable insert portion


300


to include, for example, a hook and loop fastener assembly or an adhesive. Regardless of the particular securement mechanism used to removably attach cleanable insert portion


300


to base portion


200


, in this embodiment, cleanable insert portion


300


may be removed from base portion


200


such that it may be cleaned by a user and, after cleaning, be reinserted within recess


210


such that a clean surface is now provided for floor mat


100


.




As stated above, cleanable insert portion


300


may be formed from a transparent material such as hydrophilic aliphatic acrylic polymers and copolymers incorporating acrylic acid, hydroxy ethyl methacrylate, and glycerin monomethacrylate. Forming cleanable insert portion


300


of a transparent material would allow an individual to view the customized graphics that may be provided within floor mat


100


, as discussed previously. Alternatively, the insert portion


300


could be opaque.




Additionally, the top side of cleanable insert portion


300


may include a tacky surface. The tacky surface would provide for assisting in removing debris from the soles of a person's shoes that is standing on cleanable insert portion


300


. When the top tacky surface of cleanable insert portion


300


is dirtied to such an extent that the user desires to clean insert portion


300


, in this embodiment, the user removes insert portion


300


from base portion


200


and cleans insert portion


300


to remove the accumulated debris. The insert portion


300


is then reinserted into base portion


200


.




The tacky surface that is provided on the top side of cleanable insert portion


300


could be comprised of any of a variety of materials, such as polyvinyl chlorides combined with a suitable plasticizer, plasticized neoprene, polysulfides, and polyurethanes. Additionally, acrylics, such as butyl acrylate and many of its homologues, may be utilized. Again, the present invention is not limited to any particular material. The tacky surface may be formed, generally, from any adhesive material. The only consideration, in this embodiment, is that the surface should maintain its tacky characteristic even after repeated cleaning cycles.




The present invention is not limited to any particular methodology for cleaning insert portion


300


. Insert portion


300


may be cleaned by any of a variety of methods depending upon a particular material composition for insert portion


300


. For example, insert portion


300


may be cleaned by placing insert portion within a washing machine and washing insert portion


300


or insert portion


300


may be cleaned by scrubbing insert portion


300


with a scrub brush and soap and water or with a cleaning agent such as “Spic 'N Span”.




Additionally, the insert portion


300


could be cleaned by utilizing a roller that also includes a tacky surface around the circumference of the roller. The tacky surface of the roller is comprised of a stronger adhesive than that of the tacky insert portion such that, as the tacky surface of the roller is rolled over the tacky surface of the insert portion, any dirt and debris on the tacky insert portion will be drawn off of the tacky insert portion and will adhere to the roller. In this manner, a roller with a tacky surface could be utilized to clean the tacky insert portion.




Again, however, the present invention is not limited to any particular methodology or cleaning agent for cleaning insert portion


300


and any cleaning methodology or agent compatible with the composition of insert portion


300


is contemplated.




Floor mat


100


may also include additional features for assisting in the cleaning of the soles of a person standing on floor mat


100


. For example, base portion


200


and/or insert portion


300


may include an antibacterial composition and an antifungal composition. Antibacterial compositions such as anthraquinone derivatives of polyethylene glycol mono- and di-methacrylate could be utilized. Thus, floor mat


100


would be bacteriacidal. The antibacterial feature would be particularly desirable because the floor mat would be able to both clean structural debris from the soles of the person's shoes and remove any potentially harmful bacteria from the person's soles as well.




Additionally, in order to further provide for a desirable sole surface prior to entering a particular area, floor mat


100


could also be provided with a fragrance. Flavones such as tricyclic molecules with aromatic substitution or organic ethers, e.g., limonoic acid, could be utilized. The fragrance is transferred from floor mat


100


to the soles of the person's shoes such that any undesirable odors are favorably masked by the fragrance.




The present invention is not only limited to utilizing an antibacterial composition, an antifungal composition, and/or a fragrance in floor mat


100


. Rather, floor mat


100


could also incorporate a variety of other substances that would assist in cleaning the soles of a person's shoes.




Any variety of structures or methods could be utilized for associating an antibacterial composition, an antifungal composition, a fragrance, or any other composition, with floor mat


100


. The substances could be applied as releasable, or dissipatable, coatings to floor mat


100


or could be releasably embedded as, for example, pellets within the structure of floor mat


100


such that as pressure is applied to floor mat


100


the substances are dispensed to the soles of the person's shoes.





FIG. 3

illustrates an alternative embodiment for floor mat


100


. In

FIG. 3

, it is illustrated that base portion


200


may include separate layers for a water dissipation component


230


and a cushioning component


240


. Water dissipation component


230


, in this embodiment, is disposed on a top side of the cushioning component


240


. However, the present invention is not limited to this particular embodiment for water dissipation component


230


and cushioning component


240


. For example, a single hybrid structure could be utilized for base portion


200


that would include the material properties to provide for both water dissipation and conforming structure.




Alternatively,

FIG. 4

illustrates that the floor mat may include both a water dissipation component, or wicking layer, and a water absorbtion layer. In

FIG. 4

, floor mat


400


includes wicking layer


410


and water absorption layer


420


. The wicking layer


410


could be comprised of polyproplene or olefins, or any other suitable material that has the properties of moving the water from the surface of floor mat


400


. The water absorption layer


420


is disposed underneath the wicking layer


410


and absorbs any water that passes through the wicking layer


410


. The water absorption layer


420


could be periodically removed and dried, such as by example only, in a drying machine.




Of course, a wicking layer


410


may be used either with or without a water absorption layer


420


and a cushioning layer, as described previously in other embodiments, and the water absorption layer


420


could be used with or without a wicking layer


410


and a cushioning layer. Additionally, both the wicking layer and/or the absorption layer and/or the cushioning layer could be used with or without a tacky portion.




Returning to

FIG. 3

,

FIG. 3

also illustrates an alternative embodiment for insert portion


300


. Whereas the previously disclosed embodiment for insert portion


300


was discussed as a single structural member that could include a tacky surface on a top side thereof, the embodiment of

FIG. 3

for insert portion


300


is comprised of a plurality of layers. As can be seen, layers


301


-


305


, comprise insert portion


300


. Each of the layers may include a tacky surface on a top side thereof, as was described previously for insert portion


300


. In use, a top-most layer, e.g., layer


301


, may be removed from its adjacent lower layer, e.g., layer


302


, and may be independently cleaned. After cleaning, the layer may be reinstalled within recess


210


on top of the exposed layer of insert portion


300


. In this manner, insert portion


300


may be cleaned by removing a top-most layer, cleaning that layer, and reinstalling that layer within recess


210


. Whereas each layer is described as being independently cleanable, it is not required that each individual layer be cleanable. Each layer may be formed of materials as described previously when discussing the embodiment of

FIGS. 1 and 2

for the insert portion.




Other alternative embodiments for insert portion


300


are contemplated. For example, whereas the previously disclosed embodiments discussed insert portion


300


as being comprised of one or more layers with a tacky surface on a top side of the layer(s), it is not required that insert portion


300


be formed with only a tacky surface on a top side thereof. More specifically, an alternative embodiment for insert portion


300


could include forming insert portion


300


as a single structural member from a material which is tacky in composition throughout the entire cross-section of the material. A material such as a blend of a noncross-linked hydrophilic thermoplastic, preferably a polyethylene glycol diacrylate with n not exceeding 15, and a hydrophobic material, such as a polyvinyl neoprene chloride, could be utilized for the insert portion of this embodiment. By forming insert portion


300


from a uniform, tacky material, the insert portion


300


does not necessarily have to be removed from recess


210


of base portion


200


to be cleaned. Insert portion


300


could be cleaned in this alternative embodiment by eroding the top surface of the insert portion as a result of use of the insert portion. Thus, by providing an erodible insert portion, the insert portion may be cleaned by the erosion of its top surface as the insert portion is used within floor mat


100


.




As insert portion


300


erodes, the exposed surface of insert portion


300


continues to be tacky in composition because of its uniform cross-section. As the exposed tacky surface erodes, the dirt captured by the exposed tacky surface will dissipate as a result of the erosion and thus, the erosion of the insert portion itself provides for a cleanable insert portion.




Alternatively, even with a uniform cross-section of a tacky substance for insert portion


300


, the user may remove insert portion


300


from recess


210


and separately clean insert portion


300


. Thus, the user is not required to rely solely on the erodible characteristic of insert portion


300


for cleaning of insert portion


300


; rather, the user may utilize the erodible cleaning feature of the insert portion in combination with a separate cleaning step of removing the insert portion from the base portion and independently cleaning the insert portion.




As discussed above, insert portion


300


may be comprised of a variety of materials, including materials such as tacky plastics, paper, or adhesives that can be cleanable and may or may not be erodible and reusable. If paper is utilized, the insert portion may be formed as a single structural member or as a plurality of layers, as discussed previously. Additionally, the paper may include a tacky surface on a top-side thereof. The paper may be translucent, opaque, or colored, and may include a graphic display thereon.




As discussed earlier, it is desirable, but not required, that the floor mat contain a water dissipation and/or absorption capability. This capability is desired to help prevent the tacky surface of the insert portion from becoming excessively wet and, thus, slippery. Whereas it has been discussed that, in order to help prevent a user from slipping on the tacky surface of the insert portion, a water dissipation and/or absorbing capability could be included in the floor mat to reduce the degree of moisture on the tacky surface, this is not the only structure contemplated for preventing the tacky insert portion from becoming slippery. Alternatively, the tacky insert portion itself could be formed to help prevent slipping.

FIGS. 5-12

illustrate alternative embodiments for tacky insert portion


300


.

FIG. 5

illustrates tacky insert portion


300


as including a grid pattern


320


of channels


322


that could be comprised of a non-tacky material. The channels could be either raised from the surface of insert portion


300


or could lie co-planar with the top surface of the insert portion. By forming the channels of a non-tacky material, even if the tacky material of insert portion


300


became wet, a user would be assisted in not slipping on the slippery, wet tacky surface of the insert portion by the presence of the non-tacky surfaces which do not become slippery when wet.





FIGS. 6 and 7

illustrate another alternative embodiment for tacky insert portion


300


which includes anti-slip particles


324


, e.g., silicon or sand particles, which extend above the top surface


330


of the tacky insert portion. It is desirable that the anti-slip particles be comprised of a material that does not become slippery when wet and that they be exposed from the tacky surface, however, it is not required. Even if the anti-slip particles are embedded within the tacky surface, their extension above the top surface


330


of the tacky insert portion will provide a physical frictional restraint against slipping for the soles of a person's shoes who is standing on the floor mat.




Whereas

FIG. 5

illustrates tacky insert portion


300


as including a grid pattern


320


of channels


322


that could be comprised of a non-tacky material and

FIGS. 6 and 7

illustrate another alternative embodiment for tacky insert portion


300


which includes anti-slip particles


324


which extend above the top surface


330


of the tacky insert portion, it is not required that these two alternative embodiments contain features that are mutually exclusive. For example, it is contemplated that tacky insert portion


300


could include both a grid pattern of non-tacky channels and anti-slip particles, which is not illustrated specifically in the Figures but which can be easily understood.




Another alternative for providing a slip-resistant tacky portion is to include a plurality of anti-slip members, or treads or nipples, that extend up through and slightly above the surface of the tacky portion. As can be seen in

FIG. 8

, in this embodiment, tacky portion


300


is inserted within a base portion, which may be a water absorbent border


500


, and includes a plurality of apertures


342


within it. Each of a plurality of treads


344


, which may extend upward from a base disposed underneath tacky portion


300


, extend up through one of the plurality of apertures


342


. A top-most end of each tread extends above a top-most surface


340


of tacky portion


300


. As a person steps onto tacky portion


300


, the quantity and positioning of the treads


344


is such that the tacky portion is able to remove debris from the person's shoes and the treads


344


, at least one of which is stepped upon by the person, prevents slipping of the person on the tacky portion


300


should the tacky portion


300


become slippery when wet. The treads


344


may compress when stepped upon such that the top-most end of the tread is co-planar with the top-most surface


340


of the tacky portion


300


. In this manner, the tread will contact the person's shoes to prevent slipping but yet not hinder contact between the person's shoes and the tacky surface of the mat, which enhances the cleaning of the person's shoes. Therefore, there is a relationship between the distance that the tread extends above the top-most surface of the tacky portion and the compressibility of the tread; a relationship which provides the functionality discussed above.




The treads may be configured in any shape and size. Additionally, the treads may be comprised of any material which is slip-resistant when wet, such as, for example, rubber or plastics. The treads may include grooves within them to further assist in preventing a person from slipping on the tacky portion.





FIGS. 9 and 10

illustrate additional alternative embodiments for both the tacky insert portion


300


and the base portion


200


that help to prevent slipping on a potentially wet tacky portion. As can be seen in

FIG. 9

, and as discussed previously, tacky insert portion


300


is comprised of a plurality of layers


301


,


302


, and


303


. Whereas only three layers are illustrated, it can be understood that any number of layers can be utilized in the present invention. As can be seen, tacky layers


301


-


303


each contain a plurality of integrally formed raised portions


300


A. These raised portions can help to prevent a person from slipping on the tacky portion by providing increased friction between the top surface of the tacky layer, due to the raised portions, and the person's shoes. Thus, these raised portions can substantially reduce the potential for slipping on the tacky portion if it becomes wet.




The raised portion


300


A can be formed in each layer in a variety of ways and the present invention is not limited to any particular method. One method for forming the raised portions is to assemble the layers into a pad of layers and then insert the entire pad into a machine press. One face of the press is flat and the other face, i.e., that face that is facing the non-tacky, or underside, of the layers, contains an array of bosses or bumps. When the pad is pressed in the machine press, all of the tacky layers become embossed with the pattern on the press face, causing the raised portions, or embossed portions, in each tacky layer of the pad. Thus, each embossed portion is integrally formed in each layer and is comprised of an indentation on the underside, or non-tacky side, of each layer and a raised portion on the upperside, or tacky side, of each layer.




As can be understood, in the method as described above for forming the raised portions, the raised portions of each layer are aligned with the raised portions of each other layer. It is desirable, but not required, that the raised portions of each layer are aligned so that their shape may be easily maintained when the layers are stacked one upon another.




As can be seen in

FIG. 10

, base portion


200


may also be formed to be complementary to the embossed layers. The surface


200


A that defines a bottom of the recess of base portion


200


, which receives within it the tacky layers


300


, can be formed with raised portions


200


B. These raised portions are positioned so that they are aligned with the raised portions in the tacky layers. Thus, the raised portions


200


B on surface


200


A are positioned within the indentations in the lower-most tacky layer when the layers are inserted into the recess in the base portion. As can be understood, these raised portions help to retain and maintain the raised portions in the tacky layer(s), particularly when only the lower-most layer(s) remain in the floor mat. However, it is not required that the base portion be formed with raised portions in practicing the present invention. The layers may be formed with raised portions whether or not the base portion includes complementary raised portions.




In another alternative embodiment for a tacky portion, the tacky portion could also include a water dissipating capability. The tacky portion could be comprised of a hydrophobic porous structure which would assist in dissipating water from the surface of the tacky portion.





FIGS. 11 and 12

illustrate alternative embodiments for the floor mat of the present invention that provide a water dissipating capability for the tacky portion. As will be discussed, the embodiment of

FIG. 11

also helps to prevent a person from slipping on a potentially wet tacky portion.





FIG. 11

illustrates an embodiment for tacky portion


300


where the tacky layers


301


and


302


of the tacky portion define a plurality of apertures


300


C therein. The apertures of each layer are aligned with the apertures of each other layer. Thus, because of the aligned apertures in the layers, the tacky portion is able to drain surface water from the top-most surface of the tacky portion, or from the soles of a person's shoes that is standing on the tacky portion, through the apertures and to the base portion, within which the layers may be positioned. The base portion, as discussed previously, may include a water dissipation component and/or a water absorbing component which would move and/or absorb the surface water drained from the tacky portion through the apertures.




The apertures would also provide for helping to prevent slipping on a wet surface of the layers, not only by draining surface water from the surface, but by also providing for enhanced frictional contact between the shoes of the person stepping on the layer and the layer itself. The apertures provide for discontinuities in the surface of the layer which would enhance the frictional contact between the person's shoes and the layer. The edges of the surface of the layer which define the apertures would provide for this enhanced contact. The person's shoes would engage with the edges, thus enhancing frictional contact for the shoes. Additionally, the apertures would act as a suction on the bottoms of the person's shoes, e.g., like suction cups. This suction caused by the apertures on the person's shoes would also help to prevent slippage on the surface of the layer.





FIG. 12

illustrates another embodiment for the floor mat of the present invention that also provides a water dissipating capability for the tacky portion. As can be seen, tacky portion


300


includes layers


301


and


302


. Base portion


200


defines a recess where layers


301


and


302


are disposed within the recess. A surface of the base portion that defines a bottom of the recess includes a raised portion


200


C at or near a center position within the recess. Thus, the raised portion


200


C of the base portion forms a raised portion in each of the layers. As can be understood, the raised portion formed in the layers acts to dissipate surface water on the layers from the layers. The surface water will drain off of the layers under the force of gravity due to the raised portion.




Again, any number of layers may be included in tacky portion


300


in the embodiments of

FIGS. 11 and 12

.




It is also contemplated that a water absorbing powder, such as a talcum powder, could be provided in the present invention. The powder could either be integrated into the floor mat or be separately associated with the floor mat. The talcum powder would remove moisture from the soles of a person's shoes when the person stepped into the powder and the tacky insert portion could then remove the powder from the person's soles, in addition to any dirt on the soles, when the person next steps on the tacky insert portion.




The present invention also provides an apparatus and method for determining when the tacky portion, or a layer in the tacky portion, should be removed for cleaning. Since the tacky portion assists in removing dirt from the soles of the person's shoes that steps on the tacky portion, the tacky portion, or a layer thereof, will become dirty after some number of persons step on the it, assuming that any particular person's shoes are not exceptionally dirty. Therefore, it would be desirable to assist a person in deciding when to remove a dirty tacky portion for cleaning. Again, as discussed above, this determination can be made after a certain number of persons step on the mat. Thus, an embodiment of the present invention as illustrated in

FIG. 13

includes a sensor system


700


that detects the presence of a person on the floor mat


100


. The sensor system


700


may detect the presence of a person on base portion


200


and/or tacky portion


300


. Since it is assumed that a person who steps on base portion


200


will also step on tacky portion


300


, sensing the person's presence on either portion is sufficient for practicing the present invention.




Sensor system


700


includes a sensor


710


and a display device


720


, e.g., an LED, coupled to sensor


710


and disposed on mat


100


such that it can be viewed. A power source, such as a battery, may be included on an underside of the floor mat. As mentioned above, sensor


710


senses the presence of a person on mat


100


, e.g., in this embodiment on tacky portion


300


. The sensor can detect the person's presence by utilizing any of a variety of apparatuses and methods and can include sensing the pressure applied to the mat by the weight of the person standing on the mat or by sensing the motion across the surface of the mat by the movements of the person. Thus, pressure sensors and motion detectors may be utilized in the present invention. Sensor system


700


also determines the number of persons that have stepped on the mat


100


by counting the number of sensed presences. After the number of presences equals a defined number of presences, a signal is provided to display device


720


, e.g., illuminating the LED, which indicates that the tacky portion should be removed for cleaning. The present invention is not limited to removing the tacky portion at any particular number of sensed presences and the number may be adjusted based on the particular environmental conditions in which the mat is utilized. Of course, as can be understood, after the dirty tacky portion or layer is removed and/or cleaned the sensor system can be reset to begin counting the total number of presences on the newly cleaned or exposed layer.




Alarm device


720


can provide either a visual, audible, or vibratory signal and the present invention is not limited to providing any particular type of signal. For example, a visual signal could consist of a light that is illuminated when the floor mat should be cleaned and that is not illuminated when the floor mat does not require cleaning. Alternatively, the light could be continuously illuminated in one of a plurality of different colors, with each color signifying a different state of cleanliness for the floor mat. For example, a green light could signify that the mat does not need cleaning. A yellow light could indicate the mat is reaching a state of dirtiness that will soon require cleaning. A red light, which could blink on and off, could signify that it is time to clean the floor mat.




The sensor system of the present invention may be utilized with any of the embodiments disclosed for the cleanable portion, which may or may not be an insert and may or may not include layers and a tacky surface(s), and the base portion.




Whereas cleanable portion


300


has been discussed as an insert portion, it is not required that cleanable portion


300


be inserted into floor mat


100


. There exists many alternative possibilities for associating cleanable portion


300


with floor mat


100


. For example, cleanable portion


300


could be placed on top of base portion


200


or could be positioned adjacent to base portion


200


. The present invention is not limited to inserting any of the embodiments for cleanable portion


300


within base portion


200


.




For example,

FIG. 14

illustrates a tacky portion


300


and a non-tacky portion


200


, which may include a water dissipation component, a water absorbing component, and a cushioning component, as discussed previously, that are separable. As can be seen in

FIG. 14

, tacky portion


300


may be bordered within a border


500


, which may be water absorbent, water dissipative, and include a cushioning component, and may include a plurality of apertures


342


and treads


344


within it. Tacky portion


300


can include any of the embodiments previously discussed. An attachment layer


600


is positioned on an underside of both border


500


of tacky portion


300


and non-tacky portion


200


. The border


500


and/or non-tacky portion


200


may be releasably attached to attachment layer


600


. Thus, through attachment layer


600


, border


500


, and therefore tacky portion


300


, and non-tacky portion


200


are releasably attachable to each other. In this manner, it is possible to, for example, position non-tacky portion


200


outside of a person's home on the front porch and tacky portion


300


within the person's home.




Attachment layer


600


can be any of a variety of materials. All that is required is that the attachment layer be able to releasable join one portion of the floor mat to a second portion of the floor mat. For example, a hook and loop fastener assembly, e.g., Velcro®, can be used with one portion of the assembly on the attachment layer and the other portion on the underside of the first portion of the floor mat and the second portion of the floor mat. Alternatively, an adhesive can be utilized to releasably join the two portions of the floor mat to the attachment layer. Additionally, snaps, including any type of male/female connector, may be used to join the two portions to the attachment layer.





FIG. 15

illustrates a first process step in utilizing an embodiment of the floor mat


100


of the present invention. As was described previously, an embodiment of floor mat


100


includes a base portion


200


and an insert portion


300


. As can be seen in

FIG. 15

, and as was also discussed previously, a different graphic display


220


is present in the embodiment of

FIG. 15

than was illustrated in the embodiment of

FIGS. 1 and 2

. Thus,

FIG. 15

displays a “Hello” message with “smiley face” representations in the graphic


220


.




As can be seen in

FIG. 15

, in utilizing an embodiment of the present invention, a user would first step upon base portion


200


. As discussed earlier, base portion


200


may include a water dissipating and/or absorbing component and is thus able to assist in removing any moisture from the soles of the person's shoes. As was also discussed earlier, because base portion


200


, in one embodiment, also includes a cushioning component, base portion


200


conforms to the person's soles when the person steps upon base portion


200


. Whereas not illustrated in

FIG. 15

, as discussed previously, an antibacterial composition, an antifungal composition, a fragrance, or any other cleaning substance may also be associated with floor mat


100


and applied to the soles of the person's shoes when the person applies pressure to floor mat


100


.




As can be seen in

FIG. 16

, the second process step in utilizing the present invention includes the person stepping onto insert portion


300


of floor mat


100


. As discussed previously, insert portion


300


may include a tacky surface on a top side thereof for assisting in removing debris from the soles of the person's shoes. Additionally, antibacterial compositions, antifungal compositions, fragrances, or other cleaning compositions may also be included within insert portion


300


for dispensing to the soles of the person's shoes.




After the person steps onto insert portion


300


, the user then steps off of floor mat


100


. As described previously, floor mat


100


may be cleaned after an accumulation of dirt on insert portion


300


by any of the methods described previously. Insert portion


300


may be removed from base portion


200


and cleaned, a layer may be removed from insert portion


300


to be cleaned or discarded, or insert portion


300


may be cleaned through erosion of insert portion


300


. The present invention is not limited to any particular methodology for cleaning insert portion


300


of floor mat


100


.





FIGS. 17-22

illustrate further alternative embodiments for the floor mat of the present invention. As can be seen in

FIG. 17

, in this embodiment for the floor mat, floor mat


1700


includes a cleanable portion


1710


and a plurality of base portions


1720


A-D. As can be seen, cleanable portion


1710


is positioned within one of base portions


1720


A-D. In this manner, the floor mat


1700


can be customized for a particular user by interchanging the cleanable portion


1710


with one of a variety of base portions


1720


A-D. The base portions


1720


A-D can be formed in any of a variety of physical configurations and can include any of a variety of themes, graphics, or colors. Thus, a common cleanable portion


1710


may be utilized with a variety of base portions


1720


A-D.





FIGS. 18-20

illustrate another alternative embodiment for a Door mat


1800


in accordance with the principles of the present invention. As can be seen in

FIG. 18

, floor mat


1800


also includes a cleanable portion


1810


and a base portion


1820


. As discussed previously, cleanable portion


1810


is received within base portion


1820


. In this embodiment, cleanable portion


1810


is comprised of a single sheet


1810


A. The single sheet


1810


A may be tacky on a top-side thereof and may include apertures therein to receive anti-slip nipples though it, as was also discussed previously. The single sheet


1810


A, in this embodiment, may be removed and replaced with another sheet when dirty.





FIG. 19

illustrates that a plurality of sheets


1810


B-D, may be attached to each other and rolled into a roll


1830


of sheets. The sheets can be joined to each other at a perforated joint to provide for ease in separating a sheet from the roll of sheets. As can be understood, a sheet may be separated from the roll of remaining sheets and may be then inserted into base portion


1820


.





FIG. 20

illustrates that the roll of sheets


1830


may be stored in a storage device


1840


, such as, for example, by mounting the roll of sheets


1830


on a cabinet door, which may be located in proximity to the floor mat. In this manner, replacements sheets are easily organized and stored for use.




Alternatively, instead of organizing the sheets in a roll and storing the roll in a cabinet, the sheets could be folder one upon another such that they form a flat package. The package of sheets could then be stored underneath of the floor mat


1800


where individual sheets could be removed from the package and from under the floor mat, when needed, similar to the way a Kleenex® tissue is dispensed.





FIG. 21

illustrates another alternative embodiment for a floor mat in accordance with the present invention. Floor mat


2100


also includes a cleanable/scrapable portion


2110


and a base portion


2120


. In this embodiment, cleanable portion


2110


is formed, as discussed previously in this application, as a single structural member from a material which is tacky in composition throughout the entire cross-section of the material. As was also discussed previously, by forming portion


2110


from a uniform, tacky material, the portion


2110


does not necessarily have to be removed from the base portion


2120


to be cleaned. However, in the embodiment previously discussed, the cleanable portion


2110


could be cleaned by eroding the top surface of the insert portion as a result of use of the insert portion. In the embodiment of

FIG. 21

, the cleanable portion is cleaned by scraping off a top surface of approximately 2-3 microns from the cleanable portion


2110


by utilizing a scraper


2130


.




Scraper


2130


can include any of a variety of structures, however, all that is required is that the scraper be capable of removing a top surface from cleanable portion


2110


. For example, any type of scraping surface can be utilized in scraper


2130


, such as, for example, a dull knife, a razor, or a plane.




Scraper


2130


is movable on tracks


2140


,


2145


. Tracks


2140


,


2145


are adjacent to cleanable portion


2110


and base portion


2120


. Scraper


2130


may include wheels or other structures, e.g., pins, which are received within complementary structures, e.g., grooves, in tracks


2140


,


2145


. Thus, scraper


2130


is movable across cleanable portion


2110


on tracks


2140


,


2145


. The scraper


2130


may only include a scraping surface on the portion of scraper


2130


that is movable across cleanable portion


2110


. Additionally, it is not required that two tracks be utilized. The scraper could be movable within a single track.




Scraper


2130


may be moved by any of a variety of methods, including using the foot of a user to engage with the scraper to move the scraper on the tracks.




Floor mat


2100


also includes a catch basin


2150


that may be included at one or both ends of tracks


2140


,


2145


. Catch basin(s)


2150


includes a recess into which is deposited the shavings from cleanable portion


2110


after scraper


2130


scrapes the cleanable portion. Scraper


2130


moves the shavings off of the cleanable portion and into the catch basin


2150


. The shavings from the cleanable portion deposited into the catch basin may be removed from the catch basin in any of a variety of ways, including, for example, by vacuuming the shavings from the catch basin or removing a detachable catch basin, throwing away the contents from the catch basin, and reinstalling the catch basin.




As can be understood, as the cleanable portion is shaved, the scraper is commensurately lowered on tracks


2140


,


2145


such that the surface of the scraper that engages with the cleanable portion remains engaged with the cleanable portion. As such, for example, the scraper may be mounted on a ratchet mechanism such that, as the scraper is moved across a complete width of the floor mat, the scraper actuates the ratchet such that the ratchet lowers the scraper. Alternatively, the scraper could remain in the same relative position with respect to the tracks and the tracks could be ratcheted lower with respect to the base portion and cleanable portion. Additionally, the blade surface of the scraper could be lowered with respect to the scraper's structure such that the blade is moved relative to the cleanable portion and the base portion but the scraper remains in the same relative position with respect to the tracks and the cleanable portion and the base portion.




Additionally, it is not required that a base portion be utilized in the embodiment for floor mat


2100


. The cleanable portion alone can be utilized with the tracks adjacent the cleanable portion and the scraper movable on the tracks. A catch basin(s) could still be utilized. As such,

FIG. 22

illustrates an embodiment for floor mat


2200


that includes a cleanable portion


2210


without use of a base portion. Cleanable portion


2210


is adjacent to tracks


2240


,


2245


. Scraper


2230


is movable on tracks


2240


,


2245


. A catch basin


2250


may be included at one or both ends of tracks


2240


,


2245
