Abstract
Abstract A tire encircling track for increasing the grip of a motor vehicle tire on a road surface comprising a pair of molded flexible rim portions interconnected by transversely extending rib portions to form an adjustable track adapted to encircle a motor vehicle tire. An adjustable self-locking connecting means for holding the ends of the track together and for holding the track itself on the motor vehicle tire is also provided. An additional restraint is provided to hold the track on the vehicle tire prior to locking of the connecting means. In another embodiment, the entire track is molded as a single flexible unit.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
147 words
A traction increasing over-tire for a vehicle tire which in use envelopes the peripheral tread and side wall portions of said vehicle tire, said over-tire comprising: a pair of flexible rim forming members of sufficient length to be wrapped circumferentially around the vehicle tire so as to occupy positions at least partially outwardly adjacent side wall portions of such vehicle tire, said rim forming members being molded from a durable pressure and abrasive force withstandinG material, each to coil towards a circular shape corresponding in diameter to its position on the vehicle tire; traction bar means interconnected between said rim forming members and in use extending transversely across the tread portion of the vehicle tire; and connector means for securing said over-tire on said vehicle tire by connecting together opposite end portions of the rim forming members after the traction tire is installed on the vehicle tire.
Claim 2
Dependent Claim
147 words
A traction increasing over-tire for a vehicle tire which in use envelopes the peripheral tread and side wall portions of said vehicle tire, said over-tire comprising: a pair of flexible rim forming members of sufficient length to be wrapped circumferentially around the vehicle tire so as to occupy positions at least partially outwardly adjacent side wall portions of such vehicle tire, said rim forming members being molded from a durable pressure and abrasive force withstandinG material, each to coil towards a circular shape corresponding in diameter to its position on the vehicle tire; traction bar means interconnected between said rim forming members and in use extending transversely across the tread portion of the vehicle tire; and connector means for securing said over-tire on said vehicle tire by connecting together opposite end portions of the rim forming members after the traction tire is installed on the vehicle tire.
Claim 3
Dependent Claim
73 words
The over-tire of claim 1, wherein said rim forming members have continuous hoop forming portions which in use are outwardly adjacent the edges of the vehicle tire formed where the side wall portions join the tread portion of the vehicle tire, and side portions which in use are outwardly adjacent the side wall portions of the vehicle tire, said side portions being radially slotted to increase the flexibility of the rim forming members.
Claim 4
Dependent Claim
31 words
The over-tire of claim 1, wherein said transversely extending traction bar means each includes a centrally disposed longitudinal pin connecting it to the hoop forming portions of the rim forming members.
Claim 5
Dependent Claim
17 words
The over-tire of claim 1, wherein the transversely extending traction bar means are each adjustable in length.
Claim 6
Dependent Claim
53 words
The over-tire of claim 1, wherein said connector means comprises complementary members at the opposite ends of the rim forming members having interlocking means which are automatically lockable into engagement by the vehicle tire rolling thereover once the over-tire has been draped circumferentially about the vehicle tire and its two ends brought together.
Claim 7
Dependent Claim
48 words
The over-tire of claim 1, wherein said connector means includes first interlocking portions holding the end portions of the rim forming members in fixed relation to each other, and second locking portions adapted to maintain said first portions in interlocked relationship during normal rotation of the vehicle tire.
Claim 8
Dependent Claim
28 words
The over-tire of claim 6, wherein said first interlocking portions comprise sets of interlocking teeth, and said second locking portions comprise oppositely extending retractable tongues and cooperating slots.
Claim 9
Dependent Claim
31 words
The over-tire of claim 1, further including a restraint extending between opposite end portions of the over-tire to hold same on said vehicle tire prior to engagement of said connector means.
