Description

BACKGROUND

Field

Embodiments are related in general to floor mats and, in particular, protective floor mats with improved rigidity and non-slip backing for use in automobiles.

Description of Related Art

Protective floor mats are generally used in automobiles to protect the interior carpeted surface of an automobile, such as the carpeted flooring. The floor mats are placed on top of a carpeted surface on the floor of the automobile to protect the carpeted floor surface from stains, dirt, and wear. Some protective floor mats known in the art have the tendency to bend or curl over time after normal use due to their lack of rigidity. Bending or curling of the protective floor mat is a potential problem that may present a hazard for the driver of the automobile if any portion of the protective floor mat obstructs a brake pedal or accelerator of the automobile. Some protective floor mats known in the art have the tendency to slip or slide laterally on top of the floor of an automobile. Sliding of the protective floor mat, especially if it also has a tendency to bend or curl, could obstruct the brake pedal or accelerator.

SUMMARY OF THE INVENTION

Presented herein is an improved protective floor mat, and in particular, a protective floor mat for use in automobiles. The present invention relates to a protective floor mat with increased rigidity to prevent bending or curling of the floor mat. The present invention also includes a non-slip surface or backing to prevent the floor mat from laterally sliding or shifting from its intended position.

DETAILED DESCRIPTION

Several embodiments with reference to the appended drawings are now explained. Whenever the shapes, relative positions and other aspects of the parts described in the embodiments are not clearly defined, the scope of embodiments is not limited only to the parts shown, which are meant merely for the purpose of illustration. Also, while numerous details are set forth, it is understood that some embodiments may be practiced without these details.

FIG. 1 is a perspective view of a floor mat 100. The floor mat 100 is preferably formed in a rectangular or square planar shape, but it may be generally formed in any appropriate planar shape suitable for use as an automobile floor mat. The floor mat 100 includes a top surface 101 that may optionally include a friction surface 102. The friction surface 102 may include a series of ridges, lines, bumps, nubs, or the like, to increase friction of the top surface 101 so that a driver who steps on the floor mat 100 does not slip. In the embodiment shown in FIG. 1, the friction surface 102 includes a series of raised linear lines 103 that are parallel to each other. In this embodiment, an outer border 104 of the top surface 101 of the floor mat 100 surrounds the friction surface 102.

FIG. 2 is a perspective view of a bottom surface 105 of the floor mat 100 shown in FIG. 1 in an upside-down position. FIG. 3 is a top view of the bottom surface 105 of the floor mat 100 shown in FIG. 1 in an upside-down position. FIG. 4 shows a magnified perspective view of the bottom surface 105 of the floor mat 100 shown in FIG. 2. The bottom surface 105 includes an interior cavity 106 that is defined by a surrounding wall 107 and an interior base surface 108. Within the interior cavity 106, a first set of a plurality of interior walls 109 extends from one end of the surrounding wall 107 to the other end and extends vertically from the interior base surface 108. In this embodiment, the first set of the plurality of interior walls 109 are parallel to each other. A second set of a plurality of interior walls 110 extends from one end of the surrounding wall 107 to the other end and extends vertically from the interior base surface 108. The second set of the plurality of interior walls 110 are parallel to each other. The first set of the plurality of interior walls 109 intersect with the second set of the plurality of interior walls 110 at a plurality of intersections 111. In this embodiment, the first set of the plurality of interior walls 109 perpendicularly intersects with the second set of the plurality of interior walls 110 at 90 degree angles. In another embodiment, the first set of the plurality of interior walls 109 and the second set of the plurality of interior walls 110 may intersect at greater than or less than 90 degrees.

FIG. 5 shows a magnified front perspective view of one of the plurality of intersections 111, which is a close-up view of one of the intersections 111 in FIG. 2 (shown in a circle in broken lines). FIG. 6 shows a magnified rear perspective view of the one of the plurality of intersections 111. In this embodiment, a one of a plurality of nubs 112 are positioned at each one of the plurality of intersections 111. In another embodiment, some intersections 111 may lack a nub 112. In this embodiment, each one of the plurality of nubs 112 may have an overall shape of an angled tooth. The nub 112 may include a long nub portion 112a and a short nub portion 112b as shown in FIGS. 5 and 6. The long nub portion 112a may extend from the interior ceiling 108 and beyond a height of one of the first set of the plurality of interior walls 109. As shown in FIGS. 5 and 6, the first set of the plurality of interior walls 109 and the second set of the plurality of interior walls 110 have greater width at the base of the wall relative to the width at the top of the wall.

FIG. 7 shows a magnified top view of one of the plurality of intersections 111. FIG. 8 shows a magnified front view of one of the plurality of intersections 111. As shown in FIGS. 7 and 8, the long nub portion 112a may have a contour shape of an angled tooth that extends beyond the thickness of a width of the interior wall 109. FIG. 9 shows a magnified rear view of one of the plurality of intersections 111. As shown in FIG. 9, the short nub portion 112b may also have a contour shape of a bottom portion of the angled tooth that extends beyond the thickness of the width of the interior wall 109. In this embodiment, the short nub portion 112b may extend from the interior ceiling 108, but not beyond the height of one of the plurality of interior walls 109. FIG. 10 shows a magnified side view of one of the plurality of intersections 111. As shown in FIG. 10, one of the second set of the plurality of interior walls 110 may be positioned in between the long nub portion 112a and the short nub portion 112b. The long nub portion 112a and the short nub portion 112b may be separated by one of the second set of the plurality of interior walls 110.

In one embodiment, the plurality of nubs 112 may be on the same plane or common plane as the first set of the plurality of interior walls 109. Just as the first set of the plurality of interior walls 109 are parallel to each other, the plurality of nubs 112 may be parallel to each other as well. In another embodiment, the plurality of nubs 112 may be on the same plane or common plane as the second set of the plurality of interior walls 110.

The plurality of nubs 112 may be asymmetrically shaped. In this embodiment, the plurality of nubs 112 may have the shape of an angled tooth. In another embodiment, the plurality of nubs 112 may be symmetrically shaped in a straight tooth configuration. The shape of the plurality of nubs 112 may vary widely, as long as they may provide sufficient friction when in contact with the floor of the automobile so that the floor mat 100 does not slip or shift from its intended position. For example, the plurality of nubs 112 may be cylinders, a series of loops, hooks, or cleats.

As shown in FIG. 2, the plurality of nubs 112 may extend beyond a height of the outer border 104 and a height of the surrounding wall 107. In FIG. 2, the height of the outer border 104 and the height of the surrounding wall 107 may be the same height. This may further increase friction in situations where the floor mat 100 is placed on carpeted flooring of an automobile because it allows the plurality of nubs 112 to dig deeper into the carpeting flooring. In one embodiment, the surrounding wall 107 may extend below the height of the outer border 104. In another embodiment, the surrounding wall 107 does not extend below the height of the outer border 104.

In one embodiment, the floor mat 100 may be made of rubber polymer, vinyl polymer, PVC, polyurethane, foam rubber, recycled rubber, natural rubber, synthetic rubber, silicone, thermoplastics, and other polymers. In a preferred embodiment, the floormat 100 may be made through injection molding techniques as known in the art.
