Antislipping device for cars in a stationary state

Claim 1

An antislipping device for vehicles in a stationary state, comprising: means for detecting the rotation of one or more wheels of said vehicle and outputing a signal indicating whether or not said wheels are in a state of rotation; means for detecting when an accelerator pedal of said vehicle is moved past a predetermined position and outputing a signal indicating the same; means for holding a brake pedal of said vehicle in a braked position after said brake pedal has been moved into a braked position, comprising; a retainer plate integrally formed with said brake pedal, having a plurality of aligned holes, each of said holes being provided with a taper on one inner side wall; a longitudinal housing having a cavity therein and being provided with an opening at one end portion and a through hole at the other end portion, said housing being mounted in proximity to said retainer plate so as to place said through hole opposite said retainer plate; a slide bolt slidably mounted within said housing so as to be able to extrude out of said housing through said through hole for a predetermined length and penetrate one of said holes in said retainer plate and also be able to retreat into said housing; a cover that covers said opening of said housing; means for urging said slide bolt to extrude from said through hole for a predetermined length so as to cause said slide bolt to penetrate one of said holes in said retainer plate, said tapers on said inner wall of said holes being configured so as to force said slide bolt, against said urging means, to retreat into said housing when said brake pedal is moved into a position corresponding to a greater degree of braking; electromagnetic means for forcing said slide bolt against said urging means so as to retreat into said housing in response to a control signal from a control means; control means electrically connected with said rotational detecting means, said accelerator detecting means and said holding means, for receiving said signals from said detecting means and outputing a control signal to said holding means so as to cause said electromagnetic means to force said slide bolt to retreat into said housing when either said wheels are in a state of rotation or said accelerator pedal is moved past a predetermined position.
