Definitions

  • This invention relates to a door mat.
  • this invention relates to the heavy-duty molded door mats which have usuallyhitherto been made of rubber and which have the function of removing gross adherent mud or slush before the user enters a building.
  • the present invention consists in a door mat a portion of which is provided with a raised rim to define a shallow container for water, and having upwardly extending flexible members within the rim so as to protrude above the water level.
  • the mat according to the invention will be supplied with water within the rim so that when mud is removed from the shoe by moving the shoe to and fro against the upstanding flexible members (such as spikes or ribs) within the rim the mud is softened and washed from the tops of these points or ribs by the water. Since the upstanding portions will generally be flexible, they will bend into and out of the water as the mat is used and this will in effect wash them clean and ensure that they are continuously useful for their cleaning function.
  • the upstanding flexible members such as spikes or ribs
  • the mat will usually be provided with upwardly extending flexible members over the whole or the greater part of its surface, and the rim defining the area for containing water will surround some but not all of these flexible members. In this way gross adherent material can be removed outside of the rim and the region within the rim, provided with water, can be used for cleaning the remaining mud from the shoe more effectively.
  • the flexible members can be ribs extending transversely to the direction of movement of the foot (and accordingly generally longitudinal, referred to the usual shape of door mats) or may be upwardly extending spikes or nodules.
  • the flexible members may be arranged in a regular or a random pattern.
  • ribs may be integral parallel unbroken upstanding ribs or may be arranged as short aligned ribs in parallel rows.
  • spikes are used, they can be arranged in a generally hexagonal pattern for ease in molding.
  • the mat may if desired have an upwardly extending rim extending all the way around the periphery in addition to the rim extending around the area suitable for containing water.
  • a preferred design of mat has in addition to the area for containing water and to other areas containing upwardly extending flexible members such as spikes or ribs, one or more relatively plain areas so that theuser can stand on such area with one foot while mo'ving the other foot and without permanently deforming any spikes or ribs. If necessary the area to be stood on can be suitably marked or indicated.
  • Another optional but advantageous feature according to the present invention is to have the back of the mat provided with score lines or crease lines whereby it can be folded to a smaller size for transport and cleaning.
  • score lines or crease lines can be provided extending across the back of the mat behind the rim which defines the water-containing area.
  • the mat can have a variety of shapes and still fall within the invention, it is generally envisaged for it to be between 2 and 4 feet long and between 9 and 18 inches wide.
  • the overall thickness of the mat that is to say the thickness of the base plus the height of the upwardly extending portions, will generally be from to 2 inches.
  • these numerical limitations do not affect the broad scope of the invention as defined above.
  • FIG. 1 is a general diagrammatic plan view of a mat according to the invention
  • FIG. 2a is a similarly diagrammatic plan view of an alternative embodiment of a mat according to the invention.
  • FIG. 2b is a section through the mat of FIG. 2a in the longitudinal direction
  • FIG. 3 is a diagrammatic plan view of a further embodiment of a mat according to the invention.
  • a door mat is composed of molded rubber or synthetic elastomeric composition and consists of a flat base 1 from which a plurality of spikes 2 extend upwards.
  • a rim 3 extends all the way around a central portion of the mat, and within the rim a further array of spikes 4 extends upwards. (It will of course be apparent that the spikes shown should extend over the whole of the relevant areas).
  • the upstanding rim 3 defines a tray for holding a supply of water, usually in such a way that the spikes protrude from the water but can be deformed to pass into it when the mat is in use.
  • the spikes 2 and 4 and the rim 3 all extend to the same height.
  • FIG. 2a a generally similar arrangement is shown, except that an upwardly extending rim 5 extends around the whole mat and, by virtue of two cross members 6, defines the central area for holding water.
  • the spikes 2 and 4 are replaced by ribs 7 and/or 8 as shown. (It will be apparent that these ribs and the spikes 4 as shown in FIG. 2a extend over the whole of their relevant areas, and that the exact configuration of the ribs is optional).
  • flexible ribs could replace the spikes 4 within the water-holding area defined by the rim 5 and the cross-members 6.
  • FIG. 2b is a cross-section through FIG. 2a. It will be apparent from FIGv 21) how the various ribs and spikes extend to the same general level as the surrounding rim 5 and cross-members 6. Moreover, it will be clear that the rim 5 and cross-members 6, as well as the spikes 4, are upwardly tapered so that the mat can be readily molded and removed from the mold, while still providing ribs of a suitable strength and flexibility. Moreover, in FIG. 2b the arrows 14 indicate a suitable location for a fold line extending across the mat on the back thereof so that the end portions can be folded around the central portion when it is desired to transport the mat.
  • FIG. 3 again shows an embodiment of a mat according to the invention in which there is surrounding rib 5 and various integral cross-members 9, 10, l1 and 12 defining various compartments.
  • the central compartment 13 is intended to contain water and again it is provided with spikes 4 as shown in the preceding embodiments.
  • the spikes 2, which are outside of the central water holding compartment, are less deformable than the spikes 4.
