Universal mat with removable strips

Abstract
A rubber or plastic floor mat has a series of parallel upper ribs (130) on its upper surface which define slots (110) in which respective strips (10) or carpeting or the like are removably held. The strips are retained along their lengths by retaining means which run continually or continuously along the slots. The strip retainers include hook-and-loop fastening (e.g., VELCRO), and/or overhanging edges above the strip edges, preferably formed in one-piece fashion along the side of the upper ribs adjacent the slots. The overhangs may be interrupted, e.g., crenelated as seen from above, and may include bevels.
Description




FIELD OF THE INVENTION




The present invention relates to floor mats.




REVIEW OF THE RELATED TECHNOLOGY




In the past, floor mats were made for specific purposes. Mats were made for entrance ways, commercial kitchen fatigue mats, oil resistance, snow and water removal, etc. Most of the above uses required specific mat constructions to perform whatever use was required. Sometimes it took more than one supplier to provide all of the requirements. If one mat supplier tried to cover the field, the investment in machinery, people, and skills made it very expensive to react to the demand. Warehousing alone was expensive in order to have the specific purpose product on demand.




Known floor mats, for example as shown in U.S. Pat. Nos. 3,703,059 and 4,796,399 to Kessler et al, include a framework formed of crossing ribs attached to one another at the crossing points. The ribs are usually made of plastic and are either welded together or are integrally molded in one piece. The ribs cross at right angles, with the lower tier of ribs resting on the floor.




Mats of the type shown in Kessler USP '399 have included carpet strips held between pairs of adjacent upper ribs. The carpet strips are typically formed with a thermoplastic backing from which bundles of fibers extend. The plastic backing of the strip is adhered to the top sides of the lower ribs where it passes over them, or is attached by clips.




These mats have many advantages for use where people's shoes may be quite muddy or wet, and also provide anti-fatigue support. The areas between the carpet strips let water drain down into the space between the lower tier of ribs on the floor, keeping the carpeting relatively dry and avoiding puddling on the carpet itself. The mats are low in cost as compared to carpeting.




It would be a tremendous advantage if a mat could be provided which could be stocked in an intermediate condition and then finished when the requirements from the field were requested. But this is not possible with the previously known mats in which the carpet strips are substantially permanently fixed, i.e. are either not removable at all without destroying the mat or are removable only with considerable difficulty. This means that the carpet strips cannot be taken out easily for cleaning or replacement, and they cannot be placed in arbitrary patterns of color or type to match particular applications, and they cannot be replaced by other types of strips, e.g. abrasive strips, slit tire casing strips, hardwood flooring strips, decorative vinyl or other types of flooring strips, etc., depending on the purchaser's requirements or wishes.




SUMMARY OF THE INVENTION




Accordingly, the present invention has an object, among others, to overcome deficiencies in the prior art such as noted above.




The present invention thus provides a backing framework for a floor mat having anti-fatigue properties and also having slots in which various types of strips can be fastened, making the strips removable and replaceable.




In a first embodiment of the present invention, the edge of the carpet strip or other surfacing strip protrudes slightly and fits into side grooves which partly define the slit, which is preferably formed between the upper surfaces of the lower ribs and an overhanging edge running alongside of the upper ribs on each side of the carpet strip.




A similar embodiment is described and illustrated in prior provisional application Ser. No. 60/079,120, filed Mar. 23, 1998. Unlike the embodiment illustrated in Ser. No. 60/079,120, the overhanging edge or protrusion is interrupted or tooth-like, i.e. there are interruptions of the overhanging edge along the direction of the strip. The overhanging edge, when viewed from above, has a generally crenelated or square-wave shape.




Preferably, the shape of the overhanging edge is also different from that shown in application Ser. No. 079,120. In the '120 application the cross section of the overhang, taken on a plane perpendicular to the extension of the strips, is triangular. In the present invention the preferred shape of the corresponding cross section is a rectangle, optionally with the lower corner beveled on the side facing the strip. Most preferably, it comprises an extension of the upper ribs of the mat running in the same direction as the strips and edges.




In a second embodiment, the carpet strip and the bottom of the slot are lined with many upstanding hook-like projections of the type which appear in hook-and-loop fastening strips, such as the type sold under the name VELCRO, which projections adhere the bottoms of the strips to the slots. The hooks are preferably formed on the upper surface of a plastic strip and the strip is adhered to the bottom of the slot of the backing framework. The loop material, which can simply be cloth, forms (or is adhered to) the bottom of the carpet strip. Thus, the carpet strips can be simply peeled out of the slots when they require replacement or cleaning. Since the hook material is covered at all times during use, the hooks are not damaged and remain usable for a long time.




The invention contemplates all combinations of the features of the two embodiments discussed above (and also all those of application Ser. No. 60/079,120), for example a combination of the overhanging edge or protrusion with the hook-and-loop fastening.




The strips can be arranged in arbitrary patterns of color, texture, or material. Also, various types of inserts with loop material adhered to the bottom thereof can be used in various combinations. For example, in place of the usual plastic/fiber bundle carpet strips, wooden strips can be used; this will greatly increase the attractiveness of the mat. Strips can be easily changed to suit various conditions.




The lower ribs can optionally be made thinner under the carpet strips. The backing or framework is much less stiff across the strip insertion direction and provides good anti-fatigue properties.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




The reference numerals follow those of provisional application Ser. No. 60/079,120.





FIG. 1

shows a carpet strip


10


with a rigid or semi-rigid backing strip


12


made of plastic or rubber. The strip


10


has two opposed edges


14


and a central area


16


with embedded carpet fibers


18


.




The strip


10


slides into a slot


110


of a backing or framework


100


as indicated by the dashed lines. The edges


14


are held in side grooves defined by overhangs or protrusion portions


132


extending into the slot


110


from a pair of adjacent but separated upper ribs


130


.




The framework


100


has two major structural parts, the parallel upper ribs


130


running in one direction and lower ribs


150


running in a transverse direction to the upper ribs


130


, preferably at 90° from one another. The lower surfaces of the lower ribs


150


rest on the floor (not shown) and the upper surfaces of the upper ribs


130


are at the walk-on surface level. The framework


100


is preferably molded of semi-rigid plastic or rubber as one unit, but the upper ribs


130


and the lower ribs


150


can also be welded or otherwise fastened together from discrete elongated (e.g. extruded) stock to make up the framework. The preferred stock pieces are of plastic, e.g. PVC, polyester, nylon, polyolefin, TPR, urethane, or any other plastic, with a rectangular cross-section, and may be hollow (e.g. round, partly curved or square-section tubing).




In the preferred embodiment the space at the bottom of the slot


110


is reinforced with braces


137


which run between lower ribs


150


, parallel to the upper ribs


130


. These preferably have a lesser cross-sectional area than the ribs


130


.




The braces


137


are placed close to the protrusion portions


132


so that the edges


114


of the strip


10


are firmly held, in the vertical direction, between the braces


137


and the protrusion portions


132


.




Molded-in blocks


139


may bridge between the braces


137


. Extending from the floor level to the bottom of the slot


110


, they provide additional support when someone walks on the carpet strip


10


after it is inserted into the slot


110


. Similar support may be provided by posts


135


extending to the floor level from the undersides of the upper ribs


130


where they span across a gap between two lower ribs


150


.




The end opening


111


of the slot


110


is open to receive the carpet strip


10


. At the other end of the mat (not shown in

FIG. 1

) the lower portion of the end corresponding to opening


111


is blocked, up to the height of the top of the inserted backing strip


12


, by a molded-in slot end stop wall. The stop wall may optionally extend upward to the upper surface of the upper ribs


130


. With the slot end stop wall, the inserted end of the strip


10


cannot pass out of the slot


110


past the other side (not shown) of the mat framework


100


. This makes strip alignment during insertion easier and prevents the strips from working out in at least one direction.




Unlike the embodiment illustrated in Ser. No. 60/079,120, the embodiment of

FIG. 1

has interruptions in the protrusion portions


132


, so that viewed from above it appears to be crenelated on either side of the slot.




The protrusion portions


132


may be of any cross-sectional shape, as viewed along the length of the slot


110


. Preferably, they are rectangular as shown. Different portions may be of different shapes. One of the preferred embodiments is shown in FIG.


4


. The protrusion portions may have any width in the horizontal direction perpendicular to the extension of the strip. Preferably they extend, horizontally into the slot


110


, not quite to the nearest edge of the adjacent brace


137


. This leaves a small gap between the overhang or protrusion


132


and the brace


137


, through which the floor may be seen when the strips


10


are absent. This gap provides clearance for downward-extending portions of a clip


30


, as discussed below.





FIG. 4

shows a portion of the mat


100


as seen looking along the slot


110


. The overhanging edge or protrusion


132


includes a bevel


133


, and lacks the square lower corner which is shown in FIG.


1


and is indicated in

FIG. 4

by dashed lines.




Preferably, as shown in

FIG. 1

, the length of each protrusion portion


312


is roughly equal to the spacing of the lower ribs


150


, but the portions


132


may be of any fixed length, of variable length, of random length, of lengths according to a mathematical pattern, and so on.




Preferably also the interruptions, where any protrusion portion


132


is lacking, coincide with the lower ribs


150


. They may be of any length, but preferably are at least as long as the width of the lower ribs


150


. Thus, the protrusions preferably are not staggered in the preferred and illustrated embodiment. The present invention contemplates any shapes, spacing, or other characteristic of the protrusion portions


132


.




The crenelated protrusion portions


132


allow the carpet strip to be more easily inserted and removed. If the strip


10


, and/or its edges


14


, are not excessively stiff then the strip


10


can be inserted from above. If the portions of the protrusion portion


132


are staggered, insertion may be easier. The present invention also contemplates strips


10


with crenelated edges, whereby the strip


10


may be more easily inserted from above and then slid along the slot


110


to lock in place.





FIG. 2

shows a second preferred embodiment of the present invention. The mat framework


100


is similar to that of

FIG. 1

except that the protrusion portions


132


are preferably omitted. The upper surface of the mat, which ends up under the strip


10


, is preferably bridged over between the braces


137


to form a wider surface


138


on which may be spread an adhesive A (indicated by stippling). The blocks


139


, though not shown in

FIG. 2

, may optionally be retained. The structure may be like that of

FIG. 1

except that a thin (e.g. 2 mm or {fraction (1/16)} inch) layer bridges between the various stiffening members. The structure including the area


138


is preferably one-piece, for example, all molded at once of plastic.




The layer of adhesive A of any type for holding in place a strip of hook material


20


having hooks


23


on one side. The underside of the strip of-hook material


20


may also (or alternatively) be covered with the same adhesive A as on the surface


138


(or a different adhesive), for the purpose of permanently or semi-permanently attaching the strip


20


in the bottom of the slot


110


. In

FIG. 2

the strip


20


, which is preferably flexible and formed integrally of plastic, is shown outside the slot


110


for clarity, but the present invention contemplates that the mat includes strips


20


in each slot


110


. The strip


20


is shown fastened in place in FIG.


3


.




Alternatively, the upper surface of the braces


137


and blocks


139


may include hooks molded or formed directly into the preferably plastic material of the mat


100


, or hooks inserted into the slot surface in the manner of toothbrush bristles. The mat


100


may omit the lower ribs


150


.





FIG. 2

also shows a carpet strip


10


which includes on a lower side, opposite the carpet fibers


18


, a strip


13


of loop material, felt, or other stuff that the hooks


23


can grip. The grip strip


13


is preferably fastened to the strip


10


by adhesive A. Preferably, an additional intermediate layer


11


of foam rubber or the like is fastened between the grip strip


13


and the carpeting


18


. The intermediate layer may provide resilience, liquid absorption, additional carpet strip height, and so on.




When laid onto the hook strip


20


, the carpet strip


10


will immediately hold firmly to the mat framework


100


because of its grip strip


13


. The adhesive A or other fastening means preferably holds the strip


20


to the mat


100


with strength greater than the strength of hook-and-loop fasteners, so the flexible carpet strip


10


can be removed simply by peeling up one end and pulling it.

FIG. 3

shows the carpet strip held in the slot


110


of the mat


100


.





FIG. 3

is a cross-sectional view taken transverse to the upper ribs


130


and through the length of one of the lower ribs


150


(not shown in FIG.


3


).

FIG. 3

alternatively represents a mat lacking the crossed-beam construction with lower ribs


150


, i.e.

FIG. 3

might represent a uniform cross-section of an alternate embodiment of the mat


100


.





FIG. 2

shows two embodiments of a clip


30


in broken view or partial view, with one embodiment on the left and one on the right. The clip


30


prevents unintended pulling-up of the ends of the carpet strip


10


, using a hold-down crosspiece


31


which bridges over the carpet strip


10


. The best place for the clip


30


is near the end of the strip. In one embodiment both ends of the clip


30


include the puncturing arrow


33


shown on just the left end of the illustrated clip of

FIG. 2. A

mating stop or washer


35


is optionally provided to cooperate with the arrow


33


. After the strip


10


is in place, the clip


30


is pressed downward until the arrows


33


penetrate the strip


10


. Then the stops


35


can be forced over the arrows


33


from the underside of the mat


100


. The arrows


33


may pass through the mat in the small gap between the overhang or protrusion


132


and the brace


137


, or, some other space. Optionally, the arrows may also penetrate the mat.





FIG. 5

shows an slightly different embodiment of the stop


35


, a “Tinnerman clip”


35


′, which combines the two stops


35


into a single elongated piece with two holes. is also pressed over the arrows


33


. The Tinnerman clip


35


′ bridges over the undersides of the braces


137


, locking the strip


10


against the braces


137


and into the slot


110


. The washers


35


perform similarly.




Alternatively, the braces


137


may include holes for the arrows


33


. Another other means of fastening the clips is within the scope of the invention.




The other embodiment of the clip


30


has two downward extensions


37


of the crosspiece


31


and two inward extensions


39


(only one of each is shown in

FIG. 2

, on the broken right side of the clip


30


;

FIG. 3

shows a complete clip


30


with two downward extensions


37


, one on either side. The inward extensions


39


are not visible in FIG.


3


). The inward extensions


39


optionally snap under the surface


138


of the mat


100


, or the braces


137


, locking the strip


10


in place. The inward extensions


39


may also be crimped into place or formed by bending the downward extensions


37


inward after they are inserted past the undersurface of the mat


100


, and over the undersides of the braces


137


. The clip


30


may be of any material.





FIG. 3

shows the clip


30


its mounted position as described above. The clips


30


may be removed prior to removing the strip


10


.




As long as the removable strip


10


is even moderately flexible, it will be possible to peel it out of a slot


110


for cleaning or any other reason once the clips


30


are removed. The present invention therefore provides great flexibility in using the mat for different functions in a variety of situations. Besides carpet, the strips


10


can include any other flexible material (or more rigid materials, especially if they are notched perpendicular to their length in the embodiment of FIG.


1


); they may include abrasive strips, and may alternate strips of different materials. The mat may be provided in lengths of 4 to 8 ft. to adequately brush the shoe bottom dry. Where appearance is more important, decorative strips can be used, e.g. strips with slots, decorative vinyl strips, etc.; or any combination of the above strips can be used to achieve a particular objective.




The mats may also be assembled in sections, as is disclosed in U.S. Pat. Nos. 5,958,538 and 5,882,764, the contents of which are entirely incorporated herein by reference. Preferred dimensions of the sections are 18″ by 24″ or 26″, which can be assembled into sizes such as 3 feet square, 4 feet square, 4 feet by 4 and ½ feet, or 6 feet by 3 feet.




Instead of the adhesive or adhesives A disclosed above, the various parts of the present invention may be attached with fasteners (e.g. rivets or staples), may be welded together (e.g. ultrasonic welding), or may be fastened by any other means.




An alternative construction contemplates reversing the hooks and loop or felt, so that the mat or backing


100


would include the loop layer and not the hook layer.




Any sort of elongated strip retainer or means for removably holding the strips


10


in the mat


100


is within the scope of the invention, and not just the preferred embodiments of elongated retainers including the protrusions


132


, the hook-and-loop fastening system, and combinations of those.




The present invention differs from previous inventions in that the strips


10


can be inserted into the slots


110


and also removed from above the mat


100


, by pressing or pulling. In the embodiment in which the overhanging edge or protrusion


132


includes a bevel


133


, the strip


10


requires less force to be removed than inserted when the bevel


133


is on the inside lower corner, as illustrated in the drawing. This is useful because less force can be applied in pulling (e.g., with fingers) than in inserting (e.g., by leaning on an stick). (If the bevel is alternatively on the inside upper corner—this is not illustrated—then the strip


10


will be relatively more difficult to remove and easier to insert.)




The framework


100


is considered to be a “flow-through mat” configuration because ribs


130


and


150


define a plurality of openings


200


that allow water and debris to fall through framework


100


. The invention also provides drain openings


202


that allow water to drain from slots


110


.




The foregoing description of the specific embodiments will so fully reveal the general nature of the invention that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without undue experimentation and without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. The means and materials for carrying out various disclosed functions may take a variety of alternative forms without departing from the invention.
