ABSTRACT:
An emergency brake device for stopping the rear wheels of a vehicle comprises a wedge assembly including a frame and a resilient wedge carried by the frame operably secured to the underside of the vehicle. The wedge assembly is movable from a stored position to an operative position such that the wedge is disposed between the rear wheel and the ground thereby to stop the vehicle. The wedge is substantially triangular formed by an inclined arcuate surface for engaging against the wheel and horizontal and vertical planar surfaces. The arcuate surface and the vertical planar surface terminate into a longitudinal projection portion at an upper end portion of the wedge adapted to engage the wheel when the wedge assembly is in the operative position. The wedge assembly has a flap secured to the wedge such that its trailing end portion extends beyond an end portion of the wedge and is adapted to be disposed underneath the wheel, thereby to pull the wedge horizontally, and its leading end portion is secured to the vertical planar surface of the wedge thereby to pull the wedge downwardly.
