A compact tire deflator is disclosed in one preferred embodiment of the present invention as comprising a compact housing member having a first panel pivotally disposed in relation to a second opposing panel by means of a pivotol engagement. In structure, the housing member comprises an internal surface area being sufficient for housing at least one spike mounting assembly further disposed in pivotal relation to the pivotal engagement. Preferably, the mounting assembly is formed having one or more hollow spikes removably disposed in relation to a compression sleeve which operably engages the bottom end of the hollow spike for introduction within a spike seat. A structural stop is preferably formed in relation to the first and second panels of the housing member and the spike mounting assembly to provide a means for maintaining the first and second panels at an angular disposition to the spike mounting assembly when the compact tire deflator is disposed in an open position. In this regard, the disposition of the first and second panels of the housing member provides a means for actuating a rocking motion when a pneumatic tire rolls on or over the first panel or the second panel, whereby the housing member cants towards the rolling tire thus directing the tip of one or more hollow spikes into the tire to allow the air retained therein to vent at a controlled rate of deflation.

Compact tire deflator

An improved vehicle tire deflator that is a foldable and can be deployed by pushing it or pulling it to an extended attitude across at least one full traffic lane. The deflator includes a plurality of rocker arms that are each pivotally coupled to base supports, forming a frame that is collapsible and when extended, includes a stop arrangement for holding the rocker arms apart. The rocker arms each include a plurality of actuators that incorporate spaced center holed and countersunk spike base bosses, each boss to accommodate an end of a hollow spike and attached resilient grommet fitted therein. When a tire rolls onto a rocker arm actuator, that rocker arm is canted towards the rolling tire tread, directing a hollow spike sharp and into the tire tread to lodge therein as the tire continues to roll over the actuator, the resilient grommet absorbing forces as are exerted by the tire rolling over the hollow spike pointed end and the hollow spike is pulled out from its spike base boss seat and travels fully into the tire, allowing air from within that tire to vent therethrough. Alternatively, for penetrating a steel belted tire, or the like, an insert that is formed of a hard steel, or the like, and has a pointed end can be fitted longitudinally into and maintained in which hollow spike, the insert pointed end to extend beyond the hollow spike pointed end to first contact the tread of a tire rolling thereover.

Vehicle tire deflator

A vehicle tire deflator comprising a foldable and extendible frame with one or more rocker arms releasably carrying hollow spikes and having rocker arm actuators attached to the rocker arms to pivot said arms to position the spikes to enter a tire rolling over the deflator and to hold the rocker arm in position as the spike is withdrawn from the rocker arm.
