Abstract

A skid protecting device for use in combination with vehicle tires, according to which in distribution over the tire circumference there are provided holders with a plurality of gripping profiles which are arranged transverse to and in covering engagement with gripping profiles which are adapted by way of tensioning members to be connected to the outsides of the holder. The arrangement comprises at least one chain net of interengaging chain links which is located on one lateral surface of the tire. This at least one chain net has one rim portion provided with serially arranged connecting links arranged in spaced relationship to each other for connection to the holders, whereas an oppositely located other rim portion is provided with a tensioning or tightening strand extending along the last mentioned other rim portion.

Claims

1. In combination with an anti-skid chain system for a vehicle tire having an axis and tire flanks as well as a circumferential running surface therewith and which provides holding means distributed over the circumference of the tire and securely anchored to the running surface of the tire, a plurality of approximately U-formed gripping profiles extending transverse to the running surface as well as projecting laterally thereof and connected to the holding means adjacent to the tire flanks, said profiles being securely anchored in the running surface whereby fastening of the gripping profiles with the holding means occurs along the circumferential direction of the tire by chain net means having improvement therewith which comprises a tension plate means including outer longitudinal edging and a ring means welded thereto at right angles to the tire axis for the chain net means provided with a plurality of annular members, two web links embodied as hook members engaged in each ring means and located at essentially right angles to the tire flank as well as being parts of said chain net means covering the tire flank with the ring members being essentially parallel to the tire flank, adjoining pairs of hook members in tire peripheral direction being connected by one ring means, and tensioning means engaging and extending through said annular members and operable to tension said chain net means and also provided with said web links engaged with said ring means, said chain net means forming a tight mesh network substantially covering the tire flanks, said ring means and said annular members having essentially equal measurements and being equal to each other in number.

2. A combination according to claim 1, in which said ring means projects over and beyond said pertaining tension plate means thereof.

3. A combination according to claim 2, in which outer diameter of said ring means is smaller than length of said tension plate means in circumferential direction of the tire and greater than spacing of middle axes of threaded bores in said tension plate means adjoining each other in tire peripheral direction.

4. A combination according to claim 3, in which fastening screws are provided to interconnect gripping profiles and holding means, said screws being spaced circumferentially an amount less than outer diameter of said ring means.

5. A combination according to claim 4, in which thickness of said ring means is smaller than thickness of said tensioning plate means, said ring means being offset from said tensioning plate means.
