Abstract

The invention consists of a plurality of hinged panels including side rails where the panels on each end are shorter in length than the panels between them. The panel on one end is shorter in length than the panel on the other end. Both end panels are tapered in thickness and in with. The top surface is covered with projects forming rectangular cavities with the top of the long sides higher at the ends than in the mid-section. The bottom surface includes fasteners for removably attaching cleats for gripping slippery surfaces. A variety of cleats are proposed for securing the mat under different conditions. Bracing arms are provided to support the mat in an upright position when it is used as a highway warning marker. The mat is brightly colored for daytime use and the side rails and bracing arms are covered with light reflective material for use during the hours of darkness. The panels are so hinged that one half will fold over the remaining half without interference for storage.

Claims4

Dependent claims

A vehicle traction mat comprising:

a substantially rectangular body formed of a single row of hinged panel segments for providing the body with articulated adjustability;
the panel segments at each end of the mat are shorter in length than the panel segments between the end panel segments;
one of the end panel segments is shorter in length than the opposed end panel segment;
the end panel segments are reduced in thickness from an articulated end to a distal end;
the end panel segments are reduced in width from the articulated end to the distal end;
the panel segments are so connected that one half of the mat is capable of folding over a remaining half without interference;
a plurality of raised rectangular projections having a high coefficient of friction extending from an upper surface of each panel segment for frictional engagement with a vehicle tire;
said raised projections form a cavity;
the top of a long side of the raised projections are high at an end and depressed in a top mid-section;
parallel tire rails extending above and below the panel segments for providing strength to the panel segments;
a plurality of fastener means, affixed to a bottom surface of each panel segment;
a plurality of cleat means adapted to releasably engage said fastener means for securing the panel segments on a slippery or unstable surface;
and bracing arms attached to a mid-point of the mat for supporting the mat in an upright position;
and
the side rails and bracing arms are covered with light reflecting material.
