Check-point vehicle tire puncturing and deflating assembly

Abstract

This invention relates generally to devices that are used by law enforcement agencies and others for intentionally puncturing the rubber tires of a motor vehicle. More particularly, this invention relates to an assembly that can be placed in front of or in back of one or more tires of a stationary vehicle for the purpose of deploying one or more spikes from the assembly in the event the vehicle is moved. It also relates to a vehicle tire puncturing and deflating spike assembly that is compact, that protects the spikes and the person carrying them during storage and otherwise, and that is quickly and easily used in the field.

1 . A tire puncturing spike retainer assembly comprising:
 a longitudinally extending slide base;   a plurality of spikes; and   a spike holder, the spike holder being operable to hold said plurality of spikes and being permitted to slide longitudinally along the slide base.   
   
   
       2 . The tire puncturing spike retainer assembly of  claim 1  wherein the slide base further includes an anchor plate, the anchor plate being provided such that it is possible to anchor the slide base to a surface beneath the slide base. 
   
   
       3 . The tire puncturing spike retainer assembly of  claim 1  wherein the spike holder further comprises a push plate at one end of the spike holder for pushing the spike holder longitudinally along the slide base. 
   
   
       4 . The tire puncturing spike retainer assembly of  claim 1  wherein the spike holder further comprises a means for pulling the spike holder longitudinally along the slide base. 
   
   
       5 . The tire puncturing spike retainer assembly of  claim 1  wherein the longitudinally extending slide base is the shape of an isosceles trapezoid, the shorter parallel end of the isosceles trapezoid being the bottom of the longitudinally extending slide base and the longer parallel end being the top of the slide base and wherein the spike holder has a bottom surface comprising a longitudinally extending trapezoidal aperture defined within it, the trapezoidal aperture being designed to accept the trapezoidal slide base such that the spike holder is permitted to slide longitudinally along the spike base. 
   
   
       6 . The tire puncturing spike retainer of  claim 5  wherein a plurality of slide bases are used and the spike holder has a corresponding number of apertures configured to accept each slide base. 
   
   
       7 . The tire puncturing spike retainer assembly of  claim 1  wherein the longitudinally extending slide base is the shape of a “T”, and wherein the spike holder has a bottom surface comprising a T-shaped aperture defined within it, the T-shaped aperture being configured to accept the T-shaped slide base such the spike holder is permitted to slide longitudinally along the spike base. 
   
   
       8 . The tire puncturing and spike retainer assembly of  claim 1  wherein the spike holder further comprises a top surface having two opposing ramp portions that extend downwardly from the top surface. 
   
   
       9 . A tire puncturing spike retainer assembly comprising:
 a longitudinally extending slide base in the shape of an isosceles trapezoid, the shorter parallel end of the isosceles trapezoid being the bottom of the longitudinally extending slide base and the longer parallel end being the top of the slide base;   a plurality of spikes; and   a spike holder, the spike holder having an upper portion being operable to hold the plurality of spikes and a lower portion having a longitudinally extending trapezoidal aperture defined within it, the trapezoidal aperture being configured to accept the trapezoidal slide base such that the spike holder is permitted to slide longitudinally along the spike base.   
   
   
       10 . The tire puncturing spike retainer assembly of  claim 9  wherein the spike holder further comprises a means for pushing the spike holder along the slide base and a means for pulling the spike holder along the slide base.
