Transmission shifter with park lock
First Claim
1. An automotive transmission shifter and park lock comprising:
- a base adapted for mounting in an automotive vehicle;
a shift lever translatable with respect to said base;
a park lock hook pivotably mounted on said shift lever;
means for engaging said lock hook and thus preventing translation of said shift lever out of the park position;
means for spring biasing said pivotable lock hook out of engagement with said means for engaging; and
means for connecting said lock hook to an ignition switch locked park lock member, whereby once the park lock member is locked stationary said lock hook is pivoted into engagement with said means for engaging by translation of said shift lever out of the park position.

Abstract
An automotive transmission shifter and park lock is disclosed which includes a base for mounting the shifter in an automotive vehicle. A shift lever is pivotable with respect to the base and a park lock hook is pivotally mounted on the shift lever. The base includes means for engaging the park lock hook comprising an aperture disposed in the base. The park lock hook is normally spring biased upwardly out of engagement with the aperture disposed on the base. Means for connecting the lock hook to an ignition switch locked park lock cable is provided whereby once the park lock cable is locked stationary by the ignition switch, the park lock hook is automatically pivoted into engagement with the aperture in the base upon an attempt to pivot the shift lever out of the park position. This hook-type lockout of the present invention generates the principal lockout forces in the shifter itself and the shifter and hook are sufficiently sturdy to prevent distortion and insure that the vehicle transmission cannot be moved from the park position once the ignition is turned off.

14. An automotive automatic transmission shifter and park lock comprising:
-
a base adapted for mounting in an automotive vehicle; a shift lever pivotable about said base; means for connecting said shift lever to a transmission shift cable; an arcuate array of detent engaging means disposed on said base; a spring based manually actuated detent disposed on said shift lever, said detent being spring biased into engagement with said arcuate array of detent engaging means, said detent engaging means thereby defining transmission gear shift positions; a park lock hook pivotally mounted on said shift lever; means for engaging said lock hook and thus preventing pivoting of said shift lever out of the park position, said means for engaging being disposed on said base; means for spring biasing said pivotable lock hook out of engagement with said means for engaging; and means for connecting said lock hook to an ignition switch locked park lock cable, whereby once the park lock cable is locked stationary said lock hook is pivoted into engagement with said means for engaging by pivoting of said shift lever out of the park position. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. An automotive transmission shifter and park lock comprising:
-
a base adapted for mounting in an automotive vehicle; a shift lever translatable with respect to said base; park lock means for defining a stop when actuated which limits translation of said shift lever relative to said base to prevent removal of said shift lever from the park position, said park lock means being disposed on said shift lever in said transmission shifter so that all significant park lock forces are generated in said transmission shifter; means for actuating said park lock means when the vehicle engine is turned off; and said park lock means comprising a pivotable stop member, said stop member being pivotable in a first direction into engagement with said base to limit translation of said shift lever relative to said base and said stop member being pivotable in a second direction to permit translation of said shift lever relative to said base. - View Dependent Claims (31, 32, 33, 34, 35, 36)
