Abstract

Abstract The disclosure herein discloses a grip for a vehicle tire which consists of an elongated body having an inclined ramp portion, a nose portion and two parallel sidewalls tapering to the nose portion; a first series of transverse projections spaced longitudinally along the upper face of the ramp portion and a series of teeth provided longitudinally along the lower edge of each sidewall provide traction between tire and an icy surface. A second series of longitudinally spaced transverse projections along the under face of the ramp portion provides additional gripping action. For use in deep snow, however, the grip is engagedly combined with a similarly-shaped elongated body, the latter serving as the tire-engaging part of the combined device and the grip serving only as the snow traction part thereof.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 149 words
An ice and snow grip for a tire on a motor vehicle, comprising: an elongated body including an inclined ramp portion, a nose portion at the lower end of said ramp portion for insertion under said tire and two parallel sidewalls downwaRdly extending at opposite sides of said ramp portion and tapering to said nose portion, said ramp portion having tire-receiving upper face and an under face, a first series of transverse tire-gripping projections spaced longitudinally along said upper face, a series of ground-engaging teeth defined longitudinally along the lower edge of each said sidewall, a second series of transverse projections spaced longitudinally along said under face for further gripping in snow and ice, and a slide movably mounted to an end wall opposite to said nose portion, a series of teeth being provided at the lower edge of said slide for further gripping action in snow and ice.
Claim 2
Dependent Claim 149 words
An ice and snow grip for a tire on a motor vehicle, comprising: an elongated body including an inclined ramp portion, a nose portion at the lower end of said ramp portion for insertion under said tire and two parallel sidewalls downwaRdly extending at opposite sides of said ramp portion and tapering to said nose portion, said ramp portion having tire-receiving upper face and an under face, a first series of transverse tire-gripping projections spaced longitudinally along said upper face, a series of ground-engaging teeth defined longitudinally along the lower edge of each said sidewall, a second series of transverse projections spaced longitudinally along said under face for further gripping in snow and ice, and a slide movably mounted to an end wall opposite to said nose portion, a series of teeth being provided at the lower edge of said slide for further gripping action in snow and ice.
Claim 3
Dependent Claim 56 words
A grip as defined in claim 1 wherein said ramp portion sidewalls are free of teeth along the lower edge thereof from said wall portion to the first tooth for a length greater than the distance of said nose portion to first of said series of transverse tire gripping projections spaced longitudinally along said upper face.
Claim 4
Dependent Claim 28 words
A grip device as defined in claim 1, wherein said transverse projections of said second series extend from one sidewall to the opposite sidewall of said elongated body.
Claim 5
Dependent Claim 31 words
A grip device as defined in claim 1, wherein said projections of said first series are upright abutments disposed perpendicularly to the plane of said upper face of said ramp portion.
Claim 6
Dependent Claim 22 words
A grip device as defined in claim 1, wherein said nose portion has an upturned extremity for easy insertion beneath said tire.
Claim 7
Dependent Claim 23 words
A grip device as defined in claim 5, wherein said extremity has a concave upper surface for further gripping engagement with said tire.
Claim 8
Dependent Claim 25 words
A grip device as defined in claim 1, wherein said slide has a downwardly and rearwardly inclined upper edge extending away from said ramp portion.
Claim 9
Dependent Claim 205 words
An ice and snow grip for a tire on a motor vehicle comprising: an elongated body including a ramp portion, a nose portion at one end of said ramp portion and two parallel sidewalls extending at opposite sides of said ramp portion and tapering to said nose portion, a first series of transverse projections spaced longitudinally along one face of said ramp portion, a series of teeth defined longitudinally along the free edge of each said sidewall, a second series of transverse projections spaced longitudinally along the opposite face of said ramp portion, a second elongate body received in an area defined by said sidewalls, said opposite face and an end wall opposite said nose portion, said second elongated body having an inclined ramp, a nose at the lower end of said ramp and two parallel sidewalls downwardly extending at opposite sides of said ramp and tapering to said nose, said ramp of said second elongated body having a tire-receiving upper wall and a series of transverse tiregripping projections spaced longitudinally along said upper wall, and each sidewall of said second elongated body having a series of notches longitudinally spaced at the lower edge thereof for correspondingly receiving said transverse projections of said second series.
Claim 10
Dependent Claim 205 words
An ice and snow grip for a tire on a motor vehicle comprising: an elongated body including a ramp portion, a nose portion at one end of said ramp portion and two parallel sidewalls extending at opposite sides of said ramp portion and tapering to said nose portion, a first series of transverse projections spaced longitudinally along one face of said ramp portion, a series of teeth defined longitudinally along the free edge of each said sidewall, a second series of transverse projections spaced longitudinally along the opposite face of said ramp portion, a second elongate body received in an area defined by said sidewalls, said opposite face and an end wall opposite said nose portion, said second elongated body having an inclined ramp, a nose at the lower end of said ramp and two parallel sidewalls downwardly extending at opposite sides of said ramp and tapering to said nose, said ramp of said second elongated body having a tire-receiving upper wall and a series of transverse tiregripping projections spaced longitudinally along said upper wall, and each sidewall of said second elongated body having a series of notches longitudinally spaced at the lower edge thereof for correspondingly receiving said transverse projections of said second series.
Claim 11
Dependent Claim 53 words
A grip device as defined in claim 8, further comprising means for locking said second elongated body in assembly with said first-mentioned elongated body whereby the ramp portion of said first elongated body serves as a traction device in snow and the ramp of said second elongated body serves as a tire-gripping member.
Claim 12
Dependent Claim 28 words
A grip device as defined in claim 9, said ramp having an extension overhanging a toothed slide movably mounted to said end wall of said first elongated body.
