Abstract:
1. A shift lever device adapted for use in a vehicle with an activation mechanism generating a vehicle activation signal, a transmission having a plurality of shift ranges including a P shift range, a R shift range, an N shift range, a 3 D shift range and a vehicle speed sensor generating a vehicle speed signal, said shift lever device comprising, in combination: a brake activation device; a shift lever connected to the transmission, the shift lever being operated in a longitudinal and transverse direction of the vehicle so as to be selectively moved to any one of the plurality of shift ranges to shift-operate the transmission; a brake sensor connected to the brake activation device, the brake sensor generating a brake-indicating signal in response to sensing operation of the brake activation device; a stop device adjacent to the shift lever, the stop device in one condition preventing the movement of the shifter lever from the P shift range and in a second condition permitting movement of the shift lever from the P shift range to one of the N shift range, the R shift range and the 3 D shift range; a solenoid device connected to the stop device, the solenoid device moving the stop device so as to permit movement of the shift device between the one condition and the second condition; a biasing member urging the stop device toward the one condition; an electric controller device connected to the solenoid device, the brake activation device, the activation mechanism and the vehicle speed sensor, the controller device in response to the brake-indicating signal, the activation signal and the vehicle speed signal sends a signal to operate the solenoid device so as to move the stop device from the one condition to the second condition in order to release the shift lever from the P shift range and to permit the shift lever to be selectively moved to one of the R shift range, the N shift range and the 3D shift range; and a guide block attached to the solenoid device, the biasing member being disposed between the solenoid device and the guide block, the biasing member urging the guide block away from the solenoid device.
