Device for locking shift lever of automatic transmission
First Claim
1. A shift lever locking device for locking an automatic transmission lever which is capable of being selectively moved to and set in one of a plurality of shift position including at least one non-driving position, said device comprising:
- a detent pin provided on said shift lever and designed to be moved in one direction in response to pressing of a button provided on said lever;
a detent plate capable of selectively latching said shift lever in cooperation with said detent pin and having a locking recess capable of receiving said detent pin when said detent pin is moved in the other direction after said shift lever is set in said non-driving position;
a movable member independent of said shift lever and said detent pin and capable of engagement with said detent pin at least when said detent pin is being brought into engagement with said locking recess and movable between a lock position where it engages with said detent pin so as to prevent said detent pin from moving and an unlock position where it is disengageable from said detent pin to allow said detent pin to move, said movable member including a first lever engageable at one end with said detent pin and a second lever pivotably connected at one end with the other end of said first lever, the other end of said second lever being pivoted on said detent plate; and
a lock member independent of said shift lever and said detent pin and movable between a first position where it retains said movable member against movement from said lock position and a second position for movement of said movable member to said unlock position and capable of being moved from said first position to said second position when a predetermined condition is met while said shift lever has been set in said non-driving position.

Abstract
An automatic shift lever locking device is capable of locking the shift of an automatic transmission in a specific non-driving shift position against movement from this position unless a predetermined condition is met. The device has a detent pin provided on the shift lever and movable in response to pressing of a push button on the shift lever, a movable member engageable with the detent pin, and a lock member engageable with the movable member so as to prevent the detent pin from moving out of a lock position thereby to maintain the shift lever locked in the non-driving position. Therefore, when the shift lever is not locked, the manual force exerted by the driver on the push button is not transmitted to the lock members and other parts mechanically or electrically connected to the lock member.

15. A shift lever locking device for locking an automatic transmission shift lever which has a lever portion and a knob on one end of said lever portion and which is capable of being selectively moved to and set in one of a plurality of shift positions including at least one non-driving position, said device comprising:
-
a detent pin provided on said lever portion of said shift lever and designed to be moved in one direction in response to pressing of a button provided on said knob of said shift lever; a detent plate capable of cooperating with said detent pin when said detent pin has been moved in the other direction by imparting to the operator a manual sensation in response to the movement of said shift lever that indicates said shift lever has become latched in one of said shift positions, said detent plate having a locking recess capable of receiving said detent pin when said detent pin is moved in the other direction after said shift lever is set in said non-driving position; a movable member independent of said shift lever and said detent pin, and capable of engagement with said detent pin at least when said detent pin is being brought into engagement with said locking recess and movable between a lock position where it engages with said detent pin so as to prevent said detent pin from moving and an unlock position where it is disengageable from said detent pin to allow said detent pin to move, said movable member including a first lever engageable at one end with said detent pin and a second lever pivotably connected at one end with the other end of said first lever, the other end of said second lever being pivoted on said detent plate; and a lock member independent of said shift lever and said detent pin and movable between a first position where it retains said movable member against movement from said lock position and a second position for movement of said movable member to said unlock position and capable of being moved from said first position to said second position when a predetermined condition is met while said shift lever has been set in said non-driving position. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
