Abstract
Abstract A resilient guard rail assembly for use on one or both sides of a go-cart track, at dangerous curves or embankments to inhibit a go-cart from overrunning the track; said guard rail assembly including vehicle tires disposed in a tread to tread relationship with one side-wall of each tire engaging a surface, such as, the upper surface of the track. This guard rail assembly comprises a substantially continuous, ribbon-like, flexible, resilient rail section yieldingly spaced from a stationary anchor by a deformable vehicle tire which deforms or has a tendency to flex sideways, thereby absorbing substantially all of the energy transferred thereto incident to a collision thereagainst by a rapidly moving go-cart, whereby there is substantially no damage to the go-cart or the driver thereof.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
189 words
A safety apparatus to be utilized on a go-cart track, with said apparatus structurally fabricated as a guard rail assembly which is so constructed and arranged to attenuate the impact energy imparted thereto when a rapidly moving go-cart collides thereagainst, in combination comprising: at least two vehicle tires disposed in a tread to tread relationship along at least one side and substantially following the geometric configuration of a go-cart track, each tire having a substantially cylindrical outer wall defined by the tread portion thereof, with a pair of opposed, spaced apart, substantially convex side-walls connected to opposite sides of the tread portion, with each side-wall extending between said tread portion and a substantially circular bead portion of the tire; a substantially continuous, flexible, ribbon-like guard rail means having a portion disposed in a side by side relationship with a segment of the outer tread surface of each tire, said guard rail means including means for securing the ribbon-like guard rail to each tire, with said flexible guard rail extending substantially uninterruptedly from one tire to an adjacent tire; and each tire being fixedly secured to a stationary anchor means.
Claim 2
Dependent Claim
189 words
A safety apparatus to be utilized on a go-cart track, with said apparatus structurally fabricated as a guard rail assembly which is so constructed and arranged to attenuate the impact energy imparted thereto when a rapidly moving go-cart collides thereagainst, in combination comprising: at least two vehicle tires disposed in a tread to tread relationship along at least one side and substantially following the geometric configuration of a go-cart track, each tire having a substantially cylindrical outer wall defined by the tread portion thereof, with a pair of opposed, spaced apart, substantially convex side-walls connected to opposite sides of the tread portion, with each side-wall extending between said tread portion and a substantially circular bead portion of the tire; a substantially continuous, flexible, ribbon-like guard rail means having a portion disposed in a side by side relationship with a segment of the outer tread surface of each tire, said guard rail means including means for securing the ribbon-like guard rail to each tire, with said flexible guard rail extending substantially uninterruptedly from one tire to an adjacent tire; and each tire being fixedly secured to a stationary anchor means.
Claim 3
Dependent Claim
59 words
The guard rail assembly recited in claim 1, wherein the substantially continuous, flexible ribbon-like guard rail means includes means for fixedly securing said guard rail to a segment of the outer tread surface of each tire, with said flexible guard rail extending substantially uninterruptedly from the segment of one tire to at least another segment of an adjacent tire.
Claim 4
Dependent Claim
85 words
The guard rail assembly recited in claim 2, wherein the means for securing the guard rail to the segment of the outer tread surface of each tire includes said outer tread surface defining a first opening extending therethrough, with the flexible, ribbon-like guard rail defining another opening extending therethrough, said openings disposed in opposed, axially aligned relationship and fastener means extending into and through both openings for fixedly securing the flexible, ribbon-like guard rail to the segment of the outer tread surface of each tire.
Claim 5
Dependent Claim
29 words
The guard rail assembly recited in claim 1, further including means for reinforcing the interior of each tire opposite the segment of the outer tread surface of each tire.
Claim 6
Dependent Claim
25 words
The guard rail assembly recited in claim 4, wherein the reinforcing means comprises a rectangular structural plate member having a length greater than its width.
Claim 7
Dependent Claim
27 words
The guard rail assembly recited in claim 3, further including reinforcing means to strengthen each tire opposite the segment of the outer tread surface of each tire.
Claim 8
Dependent Claim
21 words
The guard rail assembly recited in claim 1, further including reinforcing means to strengthen each tire opposite the stationary anchor means.
Claim 9
Dependent Claim
36 words
The guard rail assembly recited in claim 6, wherein, the reinforcing means comprises a reinforcing plate means disposed within the interior of each tire and opposite the segment of the outer tread surface of each tire.
Claim 10
Dependent Claim
64 words
The guard rail assembly recited in claim 8, wherein the reinforcing plate means defines an opening extending therethrough with said opening disposed in axially aligned relationship with the first opening and said another opening, with said fastener means extending into and through all three openings for fixedly securing the flexible, ribbon-like guard rail to the segment of the outer tread surface of each tire.
Claim 11
Dependent Claim
48 words
The guard rail assembly recited in claim 7, wherein the reinforcing means comprises a reinforcing plate means disposed within the interior of each tire adjacent the stationary anchor means; and fastener means so constructed and arranged to fixedly secure said reinforcing plate means to the stationary anchor means.
Claim 12
Dependent Claim
160 words
A safety apparatus to be utilized on a go-cart track, with said apparatus structurally fabricated as a guard rail assembly which is so constructed and arranged to attenuate the impact energyimparted thereto when a rapidly moving go-cart collides thereagainst, in combination comprising: at least two vehicle tires disposed in a tread to tread relationship along at least one side and substantially following the geometric configuration of a go-cart track. a substantially continuous, flexible, ribbon-like guard rail means having a portion disposed in a side by side relationship with a segment of the outer tread surface of each tire; means for securing the ribbon-like guard rail to each tire, with said flexible guard rail extending substantially uninterruptedly from one tire to an adjacent tire; means for reinforcing each tire adjacent said segment of the outer tread surface of each tire; each tire being fixedly secured to a stationary anchor means; and means for reinforcing each tire adjacent the stationary anchor means.
