The present invention relates generally to automotive accessories, and more specifically to a vehicle traction mat that is placed under the drive wheels of a vehicle to provide extra traction in mud, snow, sand, or other surfaces which cause reduced traction.
As vehicles are driven in various road conditions such as mud, snow, or sand, the possibility of the vehicle being stuck increases. This is due to the reduced traction of the road. Often vehicle tires may be stuck in potholes, or ruts which are long deep tracks made by the repeated passage of the wheels of vehicles. To enable a stuck vehicle to be driven out of a rut or a pothole, for example, motorists have typically placed miscellaneous objects under the rotating tires of drive wheels, such as sand, salt, floor mats, wooden boards, and pieces of carpeting. Such objects are typically ineffective, and in some cases hazardous, as they may get caught by the rotating tire and simply fly away thus potentially injuring bystanders.
Vehicle traction mats have been known for many years and are used to provide additional traction to a rotating tire to extricate a stuck vehicle from snow, mud, sand, or any other slippery road condition. They provide an advantage in time and costs savings to stranded motorists who would otherwise have to wait for an emergency service provider truck for winching the stranded vehicle back to the roadway, and pay for that service. Some prior art mats use metal studs to engage the snow, or mud surface. Such vehicle traction mats are hard to handle and pose a risk of injury to the hands. Other vehicle traction mats rely on pins that are captivated therein, but such vehicle traction mats are complicated to make, and the pins may sometimes break off.
In one aspect of the present invention, there is provided a vehicle traction mat, comprising a generally planar main mat segment having a tire-facing surface and a road-facing surface. A plurality of spaced-apart knobs are formed on the road-facing surface, for providing traction between the vehicle traction mat and a road surface. A plurality of spaced apart knob-cleats are formed on the top surface of at least some of the plurality of spaced-apart knobs formed on the road-facing surface, for providing additional traction between the vehicle traction mat and the road surface.
The vehicle traction mat may further comprise a plurality of spaced-apart surface cleats formed on the tire-facing surface for providing traction between the vehicle traction mat and a vehicle tire.
The vehicle traction mat may further comprise a plurality of spaced-apart cleats formed on the road-facing surface and located between the spaced-apart knobs, for providing additional traction between the vehicle traction mat and the road surface.
The vehicle traction mat may further comprise a plurality of spaced-apart knobs formed on the tire-facing surface of the main mat segment, and a plurality of spaced-apart knob cleats formed on a top surface of at least some of the plurality of spaced-apart knobs formed on the tire-facing surface, for providing additional traction between the vehicle traction mat and a vehicle tire.
The vehicle traction mat may further comprise a plurality of spaced-apart cleats formed on the tire-facing surface and located between the spaced-apart knobs formed on the tire-facing surface, for providing further traction between the vehicle traction mat and the vehicle tire.
The vehicle traction mat may further comprise at least one other planar mat segment foldably connected at an edge thereof to an edge of the main mat segment via connecting means.
The main mat segment and the at least one other mat segment may have similar knob and cleat configurations on corresponding surfaces thereof.
The knobs on the road-facing surface of the other mat segment may fit between the knobs on the road-facing surface of the main mat segment when the other mat segment is folded into the main mat segment.
The knobs on the road-facing surface of the other mat segment may be offset by a different distance from the connecting means, than the knobs on the road-facing surface of the main mat segment are.
The connecting means may comprise a traverse strip of material having a reduced thickness, or a hinge.
The main mat segment, and the at least one other mat segment may have similar dimensions for an optimal overall size of the traction mat when folded onto one another in a fully folded position.
The at least one other mat segment may comprise two edge mat segments each foldably connected to the main mat segment by means of a first and a second connecting means.
The two edge mat segments may be equal in size and may each have a length that is less than or equal to half the length of the main mat segment, such that the area of the vehicle traction mat in a fully folded position is the substantially same as the area of the main mat segment.
The at least one other mat may comprise a plurality of mat edges foldably connected to the main mat segment via a plurality of connecting means.
The main mat segment and the at least one other mat segment may be generally rectangular in shape.
The main mat segment may be made of resilient material.
The knobs formed on the road-facing surface of the main mat segment may have a cylindrical shape
The knobs formed on the road-facing surface of the main mat segment may be uniformly spaced, or closely spaced in a center region of the main mat segment and widely spaced at the edges thereof.

Embodiments will now be described, by way of example only, and not limitation. With reference to
In one embodiment, shown in
In one embodiment, shown in
In one embodiment, the tire-facing surface 124 of main mat segment 120 is provided with a plurality of knobs 150 and knob cleats 160, similar to surface 122 shown in
In another embodiment, the tire-facing surface 124 of main mat segment 120 is identical to the road-facing surface 122 shown in
In another embodiment (not shown), the vehicle traction mat's surfaces 122 and 124 both have knobs, knob cleats, and cleats, but with different dimensions and distributions. For example, the surface 124 may be provided with a larger number of smaller knobs, while surface 122 may be provided with a smaller number of larger knobs. Different knob configurations may be suitable for different types of terrain. Advantageously, the traction mat may be suitable for different surfaces (mud, sand snow, or ice) depending on which surface (122 or 124) is used as a road-facing surface.
Another vehicle traction mat 200 is described with reference to
With reference to
The vehicle traction mat 200 may have a rough tire-facing surface 124 similar to that of
To fold vehicle traction mat 200, the other mat segment 110 is folded around the connecting means 130 towards the main mat segment 120 with the road-facing surface 112 coming in proximity with road-facing surface 122. To further optimize the size of the folded traction mat 200, the knobs 150 on surface 112 and the knobs 150 on surface 122 are positioned to be interleaved with one another. For example, knobs 150 of surface 122 may have spaces therebetween suitable for receiving knobs 150 of surface 112 when mat segment 110 is folded towards main mat segment 120. Additionally knobs 150 on surface 112 may be offset by a distance d1 from the center line of the connecting means, while knobs 150 on surface 122 may be offset by a distance d2 from the center line of the connecting means. The two distances d1 and d2 are different such that knobs 150 from surface 122 fit into spaces formed by knobs 150 on surface 112, and vice versa. Alternatively, knobs 150 may be staggered on the surfaces 112 and 122 so as to allow knobs 150 on surface 112 to fit in spaces between knobs 150 on surface 122, and vice versa. Accordingly, the overall thickness of the fully folded vehicle traction mat 200 is optimized for easy storage.
While the surface configuration for both the main mat segment 120 and the other mat segment 110 are shown to be similar, other embodiments where the main and other segments may be of different configurations are contemplated. For example, the dimensions and/or distribution of the knobs 150 on the road-facing surface 122 may be different than that of road-facing surface 112. This may be useful, for example, if the vehicle is stuck in a large pothole where the bottom surface of the pothole has a surface with different properties from the sidewalls of the pothole, then a one mat segment is placed at the bottom while the other rests on the sidewalls for optimal traction.
Vehicle traction mat 300 is shown to have a generally rectangular shape; however, other generally planar shapes are also contemplated. For example, main mat segment 120 may be rectangular, while edge mat segments 110 may be semi-circular, semi-elliptical, triangular, or trapezoidal. In some embodiments, the tire-facing surfaces (124, 114) are rough. In other embodiments, the tire-facing surfaces (124, 114) have spaced-apart surface cleats 140 to provide traction between a rotating vehicle tire (not shown) and the traction mat 300. The road-facing surfaces (122, 112) may be provided with knobs 150. As discussed earlier, knobs 150 may have the shape of a prism with a triangular, rectangular, square, or trapezoidal cross section. Knob cleats 160 provide extra traction to the mat with respect to the road surface. In another embodiment, the road-facing surfaces (122, 112) of the vehicle traction mat 300 may be provided with surface cleats 140 formed in spaces between knobs 150. In yet another embodiment, the tire-facing surfaces (124, 114) of vehicle traction mat 300 may be provided with knobs 150 and cleats 160 for providing additional traction between a rotating vehicle tire and the tire-facing surface. In the embodiment shown in the accompanying figures, vehicle traction mat 300 has identical surfaces, each provided with surface cleats 140, knobs 150, and knob-cleats 160. However, as previously discussed, the knobs 150 may have different sizes and spacing for each of the tire-facing and the road-facing surfaces.
Although the figures depict the knobs 150 and cleats 140 to be evenly spaced, they may be scattered around the surface of mats 100, 200, or 300 in an uneven manner, or in a staggered pattern. While the knobs are shown to be organized in straight rows along the surface of the mats, this is not necessary as many arrangements are contemplated. The spacing between knobs 150 is chosen to prevent packed snow or mud from being stuck therein thus reducing traction. In a preferred embodiment a 15-25 mm spacing between knobs 150 is contemplated. The height of knobs 150 may be in the range of 5-15 mm, but other ranges are also contemplated depending on the expected road surface condition. The diameter or side of the knobs may be in the range of 10-30 mm but other dimensions are also contemplated depending, in part on the shape of the knobs, and the terrain or road surface condition. Different size and spacing ranges are contemplated based on various considerations such as tire size, vehicle weight, and desired storage size requirements. The higher knobs 150 are, for example, the more space the mats 200, and 300 will take up when folded. In some embodiments, knobs 150 may be staggered on the surface of vehicle traction mat 100 such that knobs 150 from the edge mats 110 would fit into the spaces between knobs 150 on the main mat segment 120, when edge mat segments 110 are folded towards main mat segment 120. As a result, the effective thickness of the folded vehicle traction mat 100 is reduced. Main mat segment 120 and edge mat segments 110 may be dimensioned for optimal size when vehicle traction mat 300 is folded. For example, as best seen in
The above-described embodiments are intended to be examples of the present invention and alterations and modifications may be effected thereto, by those of skill in the art, without departing from the scope of the invention that is defined solely by the claims appended hereto.
