Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
134 words
A traction mat for vehicles, for obtaining increased traction on a road bed, said traction mat comprising; a flexible sheet member of generally rectangular shape having two ends and of predetermined thickness; sleeve means formed integrally with said sheet member at spaced intervals therealong having a length greater than the thickness of said sheet member, and extending from said sheet member along axes angled relative to the plane of said shEet member, said sleeve means being closed at one end and open at the other whereby to define blind ended socket-like openings extending from the open end of said sleeve means into said sheet member, and, metallic stud means secured within said sleeve means, having inner ends seating on said closed ends of said sleeves and outer ends extending from the open ends thereof.
Claim 2
Dependent Claim
134 words
A traction mat for vehicles, for obtaining increased traction on a road bed, said traction mat comprising; a flexible sheet member of generally rectangular shape having two ends and of predetermined thickness; sleeve means formed integrally with said sheet member at spaced intervals therealong having a length greater than the thickness of said sheet member, and extending from said sheet member along axes angled relative to the plane of said shEet member, said sleeve means being closed at one end and open at the other whereby to define blind ended socket-like openings extending from the open end of said sleeve means into said sheet member, and, metallic stud means secured within said sleeve means, having inner ends seating on said closed ends of said sleeves and outer ends extending from the open ends thereof.
Claim 3
Dependent Claim
63 words
The traction mat as claimed in claim 1 wherein said sleeve means extend from both the upper and lower sides of said sheet member, the upper said end being closed and the lower said end being open whereby to define a continuous socket for a said stud extending through said sheet member from the lower side thereof and closed at its upper end.
Claim 4
Dependent Claim
24 words
The traction mat as claimed in claim 1 wherein said sheet member around each said sleeve means is formed integrally with an increased thickness.
Claim 5
Dependent Claim
31 words
The traction mat as claimed in claim 1 including rib members formed along at least one end of said traction mat across the upper surface thereof, for engagement by said vehicle.
Claim 6
Dependent Claim
47 words
The traction mat as claimed in claim 1 including serrations formed along the upper surface of said sheet member at one end thereof and corresponding serrations formed across the lower surface of said sheet member at the other end thereof whereby successive said mats can be interlocked.
Claim 7
Dependent Claim
17 words
The traction mat as claimed in claim 1 including reinforcing rib means formed around said sleeve means.
Claim 8
Dependent Claim
