Device for thwarting vehicular stunts
This invention relates to a selective tire-impairment device attachable to a roadway surface. The device can include a lateral surface having a piercing element. The piercing element can be oriented downward to selectively impair a sidewall of a tire traveling laterally without affecting a tire traveling in a typical forward direction. The piercing element can severely damage a tire of a vehicle performing a stunt, commonly referred to as a doughnut, due to the lateral direction of travel of a tire during the stunt.
1. A car tire-impairment device, comprising:
a construct having a lateral surface, the construct made to withstand the flow of car traffic on a roadway;
a car tire piercing element extending out from the lateral surface, the car tire piercing element having a longitudinal axis extending out from the lateral surface and a lateral axis that is perpendicular to the longitudinal axis, the car tire piercing element being oriented downward and extending out from the lateral surface at an angle, wherein the car tire piercing element is configured to impair a sidewall of a car tire upon contact along the lateral axis with the sidewall of the car tire and allows the car tire to traverse, both forward and backward in direction along the longitudinal axis, over the car tire piercing element without impairing the car tire based on a combination of the downward orientation and a circular shape of the car tire.
2. The device of claim 1 , wherein the construct further comprises:
a bottom surface adapted for coupling the construct to a surface of a paved roadway;
a top surface having essentially a same shape as the bottom surface but of proportionately smaller dimensions; and
additional lateral surfaces, wherein all lateral surfaces connect the bottom surface to the top surface at an inward facing acute angle relative to the bottom surface.
3. The device of claim 1 , further comprising:
a second car tire piercing element extending out from a second lateral surface, the second car tire piercing element being oriented downward to impair a sidewall of a car tire.
4. The device of claim 1 , wherein the construct has a truncated rectangular pyramid shape.
5. The device of claim 4 , wherein the truncated rectangular pyramid shape is a truncated square pyramid.
6. The device of claim 5 , wherein the truncated square pyramid has a vertical height from about 1 inch to about 3 inches.
7. The device of claim 6 , additionally comprising three more lateral surfaces, wherein each of the lateral surfaces of the truncated square pyramid has an angle of inclination of about 25° to about 60° relative to a bottom surface of the construct.
8. The device of claim 1 ,
wherein the construct comprises a bottom surface, wherein the bottom surface is scored and is affixed to a roadway surface with an adhesive material.
9. The device of claim 1 ,
wherein the construct comprises a bottom surface, wherein an elongate spike extends outward from the bottom surface, the spike being inserted into a hole drilled into a roadway surface and being affixed therein with an adhesive material.
10. The device of claim 9 , wherein the hole comprises a pilot hole drilled into the roadway surface and wherein the elongate spike is threaded and is screwed into the pilot hole.
11. The device of claim 1 , wherein the construct comprises a polymer, a composite, a metal, or any combination thereof.
12. The device of claim 1 , wherein the piercing element is serrated.
13. The device of claim 1 , wherein at least one surface of the device has a reflective characteristic.
14. A car tire-impairment device, comprising:
a construct comprising a top surface, a bottom surface, and lateral surfaces connecting the bottom surface to the top surface at an inward facing acute angle relative to the bottom surface, the bottom surface being configured for coupling the construct to a surface of a paved roadway, the top surface having essentially a same shape as the bottom surface but of proportionately smaller dimensions, and the construct being made to withstand car traffic of the roadway;
a first car tire piercing element affixed to a first lateral surface of the lateral surfaces and a second car tire piercing element affixed to a second lateral surface of the lateral surface, the first piercing element and the second piercing element each being oriented downward, wherein the first piercing element is affixed to the first lateral surface at an angle and the second piercing element is affixed to the second lateral surface at an angle, wherein the first piercing element and the second piercing element impair a sidewall of a tire traveling laterally to the first piercing element or the second piercing element and allow the tire to travel forward or backward longitudinally over the first piercing element or the second piercing element without impairing the tire based on a combination of the downward orientation and a circular shape of the car tire.
