Definitions

  • ABSTRACT A foot grille, grating, mat, or the like comprises parallel, closely spaced bars, each of which has a shallow channel that has overhanging lips and receives and captures a replaceable carpet strip. Each carpet strip has a semi-rigid backing that imparts sufficient stiffness to the carpet to prevent it from pulling out of the bar channel.
  • This invention relates to grilles, gratings, mats and the like of the type used, for example, in building entrances for dirt removal from the footwear of persons entering the building.
  • any entrance foot grille or mat should have several important attributes. It should provide a surface that is effective in dislodging dirt from the footwear of persons treading upon it. It should be capable of retaining dirt dislodged from the footwear for subsequent removal. It should be relatively easy to clean, preferably with a self-cleaningaction on at least the surface that is walked upon.
  • the materials from which the mats or grilles are made should be capable of withstanding to the greatest degree possible the environmental conditions in which the mats or grilles are used, such as the abrading action of beingwalked upon, water, materials commonly present with water and dirt that may be carried on the footwear of persons treading.
  • rigid metal grilles are usually durable and resistant to conditions in the environment, and have a self-cleaning action, insofar as dirt removed from footwear falls into the spaces between the grille bars.
  • the hard surface of the metal grille bars usually provides only limited cleaning effectiveness.
  • pile fabrics such as carpets or fiber mats, are usually very effective in cleaning footwear, but tend to be less durable and subject to rapid wear.
  • the assignee of the present application has for some time manufactured and sold a form of rigid metal foot grille having closely-spaced interconnected metalbars.
  • the tops of the bars are provided with surfaces of various materials and forms that enhance cleaning effectiveness, durability, or attractiveness, such as plastic wearing surfaces, an abrasive material surface, a serrating of the material of the bars and the like.
  • These grilles have been widely accepted and have provided excellent service. Reference may be made to US. Pat. No. 3,383,822 for a complete description of such foot grilles.
  • grille of the type described in the abovementioned patent has surfaces on the tops of the bars constituted by strips of carpet permanently installed in shallow channels by an adhesive.
  • the pile material of the carpet is very effective in cleaning footwear, can be matched for color and carpet material to carpeting within the building in which the grille is used, and has various other advantages.
  • the carpet materials are subject to wearing out relatively quickly, and inasmuch as the carpet material is permanently glued in place on the bars, the useful life of the grille can be somewhat limited, especially when used in a high traffic area, such as the entrance to a store or an office building.
  • a novel and improved foot grating, grille, .mat or the like that is durable, highly effectivein cleaning the footwear of persons treadingelements it, is easy to clean and has, in particular, the advantage of embodying replaceable pile surface elements which enable the grille to provide virtually unlimited] service life.
  • the pile fabric element can be quickly and easily removed and replaced by new, elements.
  • a foot grille, grating, mator the like in accordance with the invention, comprises a multiplicity ofspaced-apart, elongated bars of uniform cross-section along. their .length.
  • Each of the bars includes, in cross-section, an essentially flat base portion, a flange portionalong each side of and extending up wardly from the base portion to form a shallow channel, and a lip portion extending along and inwardly from the upper edge of eachflange. portion.
  • the flanges and lips along each sideof theflat base of each bar define marginal slots along each side of the bar that receive and capture an elongated strip of pile fabric material.
  • Each pile fabric strip has an essentially flat base strip of semi-rigid material that impartssufficient stiffness to the pile fabric material to provide a dimensional and geometric stability to the pile fabric that enables the pile fabric strip to be firmly retained and'captured within the bar channel, eachmarginal edge of the pile fabric strip being firmly received and captured in-the slotsalong each side of the bar.
  • the semi-rigid base strip therefore, prevents the pile fabric from pulling out of the shallow slot and thus allows the strip to be installed and retained in place without the use of any adhesive, fasteners or any other means, apart from the capturing. of the marginal portions within the side slots on the bars.
  • Fasteners may, however, be used at the ends of the strips, or a peripheral frame or end frames provided, to prevent the strips from sliding lengthwise.
  • the bars andthe pile fabric strips of a foot grille, grating or mat may be made of variousmaterials
  • a preferred grating, grille or mat embodies bars formed, such as by extrusion from aluminum or a highrperformance, rigid plastic, to the desired cross-section and pile fabrics with piles of synthetic material, such as acrylic, nylon, polypropylene or other polymeric materials known to be appropriate for pile fabrics.
  • the pile fabric strips may be a conventional, commercially available carpet material. Indeed, the same carpet material that is used within the building where the grille or mat is installed can be used for the pile strips of the mat or grille.
  • the semi-rigid base of each Strip may be a pre-formed strip of a semi-rigid material adhered to the back face of the preformed carpet with a suitable adhesive, or a suitable backing layer of a semi-rigid material, such as a polymeric material, may be applied by spraying, extrusion or other suitable coating process to the back face of the pre-formed carpet.
  • the bottom surface of the base strip may have a dimpled or waffle pattern or texture to provide s suction action for improved resistance to pull-out of the carpet strip.
  • This type of pile fabric or carpet has, because of its construction, particularly good properties for use as the pile fabric strips in foot grilles and mats of the invention.
  • the strips can readily be cut from a web of the carpet material to precise dimensions with almost no risk of the pile tearing loose from the backing, even along the extreme edges of the cut material. It is also possible to provide a routed edge along the pile face of the carpet in which substantially all of the pile material is cut away, leaving a thin layer of the polymeric material and the fabric backing of the carpet that is captured under or within the marginal slot along each side of the grille or mat bar.
  • this type of pile fabric also permits the production of a carpet material in which the polymeric material layer by which the pile is joined to a backing is relatively stiff and can be considered as the semi-rigid base member that is important in providing sufficient rigidity in the pile fabric strip to prevent it from pulling out of the bar channel. Very good results are also obtained, however, by adhering a separate, preformed base strip of semirigid material on the back of a pre-formed conventional carpet material, either Milstar or some other carpet material of similar construction.
  • a relatively thin grille, grating or mat is obtained by uniting bars having the replaceable pile fabric strips with connector members in the form of relatively thin strips extending generally transversely of the bars and joined to the bottoms of the bars.
  • the connector strips are formed of a flexible material, such as an elastomeric, polymeric material, for example, a synthetic rubber or flexible plastic, or a fabric.
  • the use of flexible connector members in a thin form of mat permits the mat to be rolled up for storage or for cleaning the floor surface under the mat.
  • a thin form of grille or mat can be mounted in a shallow recess or pit in a floor or can be placed directly on any desired surface.
  • the bars and the connector members can be used to unite the bars to the members.
  • most materials useful for the connector members can be securely united to metal or plastic bars with an epoxy or other high-peel strength adhesive; thermoplastic bars can be united to thermoplastic connector members by ultrasonic welding.
  • a foot grille, grating or mat, according to the invention offers numerous advantages. As already mentioned, the most important advantages is that the pile fabric strips can easily be replaced when they become worn or unsightly for one reason or another. The pile fabric material provides very effective cleaning of the footwear of persons entering the building.
  • gratings and mats have a self-cleaning action, in that dirt scraped off footwear treading upon them tends to fall down between the bars and onto the floor or into a pit in which the mat or grille is installed.
  • the pile fabric provides a very attractive surface that can be colormatched to suit the environment.
  • the construction permits assembling strips of different colored pile materials or pile materials of different designs into the mat or grille to provide a desired design, emblem, numbering or lettering; in this respect it is very easy to provide a custom installation by appropriate changes in the pile material.
  • FIG. 1 is an end view in section of a portion of an exemplary grille taken generally transversely across the grille bars;
  • FIG. 2 is an end view in section of a portion of a bar of the grille in FIG. 1, the view being on a larger scale than FIG. 1;
  • FIG. 3 is an end view in cross-section of a bar having a different form of pile fabric strip installed in it, the view being also on a larger scale than FIG. 1;
  • FIG. 4 is an end view in cross-section of a portion of an exemplary thin form of mat taken generally transversely across the bars;
  • FIG. 5 is a side view in cross-section of a portion of the mat of FIG. 4, the view being taken generally along the lines 55 in FIG. 4 and in the direction of the arrows.
  • the grille comprises a multiplicity of closely spaced, parallel grille bars joined together into a rigid grille unit by connector rods 12.
  • the bars 10 are preferably continuous extrusions of uniform cross-section and formed from aluminum, brass, plastic or other suitable material and then cut to the desired length.
  • Each of the grille bars includes, in cross-section, a web portion 14, the central part of which is of reduced thickness, relative to the upper and lower parts, to provide concavities 15 in each face.
  • the web portion of each bar is formed with a series of spaced-apart, key-like holes 16 that gener ally match the cross-section shape of the connector rods 12.
  • Each connector rod (several are used to join the grille into a grille assembly) has, in cross-section, a circular center section (reference numeral 17 in FIG. 1, as viewed in elevation) and two flanges 18 and 20 extending from diametrically opposite points on the circular center section 17 and aligned on a plane that includes the axis of the center section 17.
  • the two flanges l8 and 20 of the connector rod 12 are formed with slots 22 located on centers equal to the desired center-to-center spacing between the grille bars 10.
  • the grille is assembled by inserting the connector rods 12 through the matching key-like holes 16 in the grille bars.
  • the holes 16 in the grille bars are oriented so that the rods are inserted through the bars with the flanges of the rods in a horizontal plane.
  • each connector rod is rotated about its longitudinal axis to bring the two flanges 18 and 20 on each rod 12 into a generally vertical plane, as illustrated in FIG. 1.
  • the dimensions of the slots 22 in the lengthwise direction of the connector rods 12 are slightly less than the dimensions at the corresponding locations of the web portions 14 of each grille bar. Accordingly, the web portions of the several grille bars become wedged or clampled between the opposite edges of each slot 22, and because of the dimensional relationship between the width of the slot and the thickness of the web portion where the slot walls engage the web portion of each grille bar, there is a firm frictional engagement between them which connects the bars into a strong, rigid grille structure.
  • Each grille bar 10 has, in cross-section, a flange portion 24 at the bottom of the web portion 14 and an upper portion located at the top of the web portion.
  • the upper portion is composed'of a substantially flat base portion 26 (see FIG. 2), a flange portion 28 extending upwardly from each side of the base 26 and fonning a shallow channel in the top portion of the bar, and a lip portion 30 at the top of each flange portion and extending inwardly toward the center of the bar.
  • Each flange portion 28, lip portion 30 and the marginal portion of the base portion 26 define a continuous longitudinal slot 32 at each side of the shallow channel presented by the top portion of each bar, such channel having a top opening of substantial width represented by the distance between the innermost extremities of the lip portions 30.
  • the shallow channel of the upper portion of each grille bar 10 receives a pile fabric strip 34 that constitutes the tread surface of the grille.
  • the pile fabric strip may be of various materials, but preferably is a carpet of synthetic material having a base 36 of semi-rigid material to impart stiffness to the carpet.
  • the pile fabric strip 34 in the embodiment shown in the drawing comprises a strip of carpet 38 of a type having a pile-40 of generally U-shaped loops of yarn adhered to a fabric backing 42 by a layer of a polymeric material 44 that has been formed in situ on the faric and into which the loops have been pressed during the process of manufacture.
  • this particular type of carpet provides the important advantage of being substantially free of any tendency for tearing away of the pile, in other words, an overall secure bond between the pile and the backing, it is appropriate to consider the carpet construction in some detail.
  • a carpet of this type is made by coating the backing fabric 42 with a layer of a plastisol of a polymeric material, such as polyvinylchloride, in semi-liquid or paste from and then appropriately forming and pushing the yarn loops into the plastisol coating.
  • the plastisol layer is then fused and then cooled to solidify it, and the result is a layer of plastic material that is firmly adhered to the backing and in which the pile loops are embedded with the base portions encapsulated in the layer of plastic.
  • carpet materials of this type have recently become available commercially.
  • the pile fabric strips 34 of the grille illustrated in the drawings are made sufficiently stiff to retain them in the bar channels by laminating to the carpet strip 38 a base strip 36 with an appropriate adhesive.
  • the base strip 36 is made of an appropriate semi-rigid material, advantageously a plastic, such as a medium density polyvinylchloride.
  • the strip 36 is of uniform thickness entirely across its width.
  • the pile fabric strip 34a in the embodiment of FIG. 3 is similar to that of the embodiment of FIG. 2, except that the base strip 36a has flanges 41 formed along its sides to provide a shallow recess in which the carpet material 38a is received.
  • the base strip 36a has flanges 41 formed along its sides to provide a shallow recess in which the carpet material 38a is received.
  • the strips can be made by laminating a sheet of carpet material to a sheet of the base strip material and then sawing or otherwise appropriately cutting the composite sheet into stripsof appropriate widths.
  • the strips of carpet are cut out separately, and the pre-formed base strips 36a are laminated to the individual carpet strips.
  • the upper side edges of the carpet strips are routed away to remove the pile and part of the plastic layer and thereby to leave a small lateral projection 46 along each edge of the carpet strip 38constituted by a portion of the layer 44 of plastic material of the carpet, the fabric backing 42, and the side marginal portions of the base strip 36.
  • Each of the side projections 46 has a thickness substantially equal to the vertical dimension of the slot 32 at the edges of the top portion of each bar 10, and the transverse dimension between the extremities of the two projections 46 is substantially equal or just slightly less than that dimension measured horizontally between the inner faces of the flange portions28, that is, the bases of the slots 32. Consequently, the projections 46 of the pile fabric strips 34 are received and captured within the channel at the top portion of each grille bar 10.
  • FIG. 3 also involves a similar receiving and capturing of the pile fabric strip 34a in the channel of the bar 10.
  • the width of the carpet strip 38a is substantially equal to the dimension of the top opening between the innermost extremities of the lip portions 30 of the bars 10.
  • the semi-rigid base strip 36a is dimensioned to fit firmly within the channel with the side marginal portions received and captured in the. slots 32 at each side of the bar 10. Consequently, both embodiments achieve the same result, but in a slightly different manner.
  • FIGS. 4 and 5 of the drawings illustrate a relatively thin mat having bars 50 that are substantially identical in cross-sectional shape to the top portions of the bars 10 of the grille illustrated in FIG. 1 except that the bottom surface 52 of the base portion 54 of each bar 50 is substantially flat.
  • Each bar 50 receives a replaceable pile fabric strip 56 composed of a pre-formed carpet of the type described above and illustrated in FIGS. 2 and 3.
  • the pile fabric strip 56 has a coating 60 of a polymeric material applied to the under side of the carpet strip 58.
  • an epoxy resin compound is sprayed onto the fabric backing of the carpet strip.
  • the epoxy resin Upon setting, the epoxy resin imparts substantial stiffness, that is, geometric and dimensional stability, to the pile fabric strip 56 that prevents the pile fabric strip from pulling out of the shallow channel in the bar 50.
  • substantial stiffness that is, geometric and dimensional stability
  • the bars 50 and pile fabric strip 56 in the em bodiments of FIGS. 4 and 5 are identical to the embodiments of FIG. 1 and therefore need not be described here in detail.
  • the bars 50 are united into a mat by spaced-apart, relatively thin strips 62 of a flexible material that extend transversely to the bars and across a suitable number of bars to provide a mat of the desired width.
  • the embodiment employs strips of about, say, one-eighth inch to three-fourths inch thick and from about three-fourths inch to 1% inches wide of neoprene synthetic rubber reinforced with longitudinally extending cords 64 that impart longitudinal stability to the strips.
  • the thickness of the strips may be varied to provide a mat of the desired thickness. If the mat is to be placed directly on a floor surface, then very thin strips would be used. If a pit or recess is available in the floor, relatively thicker strips may be employed.
  • the strips 62 are joined to the bottom surface of the bars by an epoxy or other appropriate adhesive, and very good bonds between the strips and the bars can be obtained with proper precautions in cleaning the bars.
  • the bottoms of the bars may be roughened or serrated to assist in forming a strong connection, but several high-peel strength adhesives are available that permit the required bond to be achieved without roughening or serration of the bars.
  • the strips may be cast in situ across the bottom surfaces of the bars and thereby be united and bonded directly to the bars. The width of the strips and the spacing lengthwise of the bars between the strips can be varied in accordance with the strength requirements.
  • each strip permits a stronger adhesive bond between the bars and the strips to be achieved; a greater overall strength in the mat is attained by spacing the strips relatively closely, say, on 4 inch centers.
  • the strips can be color-matched to the pile fabric. Rubber or plastic connector strips 62 provide a desirable moderate resiliency and good nonslip properties to the mat.
