BACKGROUND FIELD OF INVENTION

[0003] This invention relates to a small carpet runner adapted to be installed on stair steps, separately on each step, especially stairs located inside of a house. In general inside the house the stairway is covered with carpet for ornamental, flexibility and thermal insulation. The carpet on the steps become worn away more quickly than the carpet in the house and also dirties much easily. The area where the carpet is worn out and become dirty is located in the center of the stairs. The cleaning and changing of the carpet on the steps is very expensive and many times the new carpet doesn't match the old carpet in the house. The tendency is to install a narrow piece of carpet runner, made from plastic or tread, as one unit body from the top to the bottom of the stairs fixed by stair rods or screws, but it brings into existence undesirable dispersion.

SUMMARY OF THE INVENTION

[0004] It is the principal object of the invention to provide a stair steps gripper witch can protect the carpet on the steps and provide an anti-skid cushioned surface with an excellent flexibility and ornamental effect. This is generally achieved by covering a piece of semi-rigid plastic material, provided with short spikes on one side, with an antiskid and cushion material, having ornamental properties. Another purpose of this invention is to provide a stair steps gripper witch can be very easy installed on each step of the stair, witch is clear of the undesirable dispersion. Using this invention will prevent the carpet wear out, dirt on the steps and injury, due to skidding, is reduced to minimum.

DETAILED DESCRIPTION OF THE INVENTION

[0051] Description—FIGS. 1, 2, 3 and 4—Preferred Embodiment

[0052] A preferred embodiment of the stair steps gripper of the present invention is illustrated in FIG. 1. The invention has a base 60 made from semi-rigid plastic material with short but relatively sharp spikes 54 on its lower surface for penetrating into an underlying carpet 68. The vinyl plastic used to fabricate the base 60 is semi-rigid, liquid-impervious, plastic material having a predetermined durometer rating on a Rockwell C scale sufficiently high to provide enough rigidity for the base 60. The base 60 can be cut in any predetermined lengths and widths at a cutting station during the fabrication process as the formed roll leaves the forming stations. However, the base 60 can consist of any other material that can satisfy the condition of rigidity on a Rockwell C scale like polyethylene, polypropylene, vinyl, nylon, various impregnated or laminated fibrous materials, various plasticized materials, cardboard, paper, etc. The thickness of the base 60 can be typically 2 mm to 4 mm and the overall dimensions depends of the applications. The color of the base 60 can be clear, semi-transparent or colored plastic to give ornamental variations to the carpet 68. The outer four corners of the base 60 are typically beveled or rounded to avoid snagging and personal injury. The base 60 can be cut in various shapes for example rectangular, trapezoidal, circular, semi-circular, elliptic, semi-elliptic, etc. The runner 51, shown partially peeled back, is a common carpet, a short or deep pile carpet, a foot cloth or felt and can be cut in the same various shapes like the gripper. The edges of the runner 51 are protected against frying by surging 53, or covering the edges with a plastic sheet, a cloth, etc. The overall dimensions of the runner 51 can be smaller equal or bigger than the size of the base 60 because the same invention can be used to hold in place a foot cloth or a small decorative rug on the carpet. The connection between the base 60 and the runner 51 is made by an adhesive 52 witch enables the base 60 and the runner 51 to form the stair steps gripper. The adhesive 52 can be a latex adhesive, synthetic resin, adhesive tape with a good adherence and flexibility to plastic and carpet. FIG. 2 show a view in detail along its cross-section 2-2 of the front edge 56 for the base 60. The base 60 is provided on the upper surface with rigidity serrations 55 to increase rigidity and on the lower surface spikes 54 designed to secure the base 60 on the carpet 68. FIG. 3 show the preferred embodiment for the base 60 and a view in detail along its longitudinal cross-section 4-4 characterized in that the walking zone on the center has the same thickness like the edge zone.

The modified embodiment has a base 60 without spikes on the lower surface. The stair steps gripper can be attached in the back of each step with screws through the holes 62, from the base 60, and the L-shape fixture 59. FIG. 8A is a view in detail along its cross-section 8-8 (FIG. 7) characterized in that the base 60 have a strait edge 56 in the front and holes 62 in the back. To increase the anti-skid effect the lower surface (FIG. 8B) can be covered with rubber or another material with anti-skid properties 61. FIG. 9 is a view in detail along its cross-section 9-9 (FIG. 7) of the L-shape fixture 59.

FIG. 11A is a view in detail along its longitudinal cross-section 11-11 characterized in that the walking zone in the center have the same thickness like the edge zone. FIG. 11B is a modified version of the section 11-11 characterized in that the edge zones have a greater thickness than the central walking zone.

[0057] FIGS. 12 and 13 show a modified embodiment of FIG. 7, with the runner 51 partially peeled back, which is provided with a curved edge 57 and anti-skid serrations 58 in the front.

FIG. 15B is a modified version of the section in FIG. 15A characterized in a covered lower surface with an anti-skid material 61 to increase the anti-skid effect. FIG. 16 is a view in detail along its cross-section 16-16 of the U-shape fixture 63.

[0059] FIGS. 17, 18A, 18B, 18C and 19 show a modified embodiment of FIG. 12, with the runner partially peeled back, which is provided with a double edge 64, a U-shape fixture 63 in the back and a edge cover 65 in the front. FIG. 18A is a view in detail along its cross section 18-18 which is provided with a curved edge 56, in the front, and anti-skid material 61, on the lower surface. FIG. 18B is a modified version of the section in FIG. 18A characterized in a S-shape edge 66, in the front. FIG. 18C is a modified version of the section in FIG. 18A characterized in a L-shape edge 67, in the front. FIG. 19 is a view in detail along its cross-section 19-19 of the edge cover 65.
