System for preventing inadvertent locking of a vehicle door
View Patent ↗A lock mechanism ( 20 ) for a door comprising: a door handle ( 110 ) manually movable from a rest position to an activated position; a first bias spring ( 170 ) biasing the door handle to automatically return to the rest position; a lock button ( 210 ) movable from an unlocked position to a locked position, wherein when the lock button is in the locked position an associated door lock is locked, thereby preventing the door from being opened and when the lock button is in an unlocked position the door lock is capable of being opened by the door handle when it is moved to the activated position, whereby a quick release of the door handle from its activated position initiates movement of the lock button from the unlocked position to the locked position; the lock mechanism further includes a lever assembly comprising: a programmed lever ( 300, 302 ) for blocking the lock button from moving to its locked position in response to the quick release of the door handle, wherein when the lock button is in the locked position an associated door lock mechanism is locked thereby preventing the door from being opened at least from the exterior of the vehicle and wherein the lock button is configured such that when it is in an unlocked position the lock button is capable of inadvertently being moved to its locked position by at least the operation of the door handle.
1. A door lock mechanism for a door comprising:
a door handle configured to be moved from a rest position to an activated position by a user thereof;
a first bias spring biasing the door handle to return to the rest position;
a lock button movable at least from an unlocked position to a locked position, wherein when the lock button is in the locked position an associated door lock mechanism is locked thereby preventing the door from being opened at least from an exterior of a vehicle and wherein the lock button is configured such that when it is in an unlocked position the lock button is capable of being moved to its locked position by at least the operation of the door handle;
the lock mechanism and lock button being configured such that a release of the door handle under certain conditions from its activated position initiates movement of the lock button to its locked position;
the lock mechanism further includes a lever assembly for blocking the lock button from moving to the locked position of the lock button in response to a return movement of the door handle from its actuated position to its rest position
wherein the lock mechanism further includes bias means for selectively biasing the lever assembly to move toward a blocking position.
2. The lock mechanism as defined in claim 1 including stop means for preventing the lever assembly from rotating beyond a desired blocking position.
3. A door lock mechanism for a door comprising:
a door handle configured to be moved from a rest position to an activated position by a user thereof;
a first bias spring biasing the door handle to return to the rest position;
a lock button movable at least from an unlocked position to a locked position, wherein when the lock button is in the locked position an associated door lock mechanism is locked thereby preventing the door from being opened at least from an exterior of a vehicle and wherein the lock button is configured such that when it is in an unlocked position the lock button is capable of inadvertently being moved to its locked position by the operation of the door handle;
the lock mechanism and lock button being configured such that a release of the door handle under certain conditions from its activated position initiates movement of the lock button to its locked position;
the lock mechanism further includes a lever assembly for blocking the lock button from moving to the locked position of the lock button in response to a return movement of the door handle from its actuated position to its rest position;
wherein the door handle is configured to rotate about a first axis and wherein the lever means is configured to rotate about a second axis, wherein the second axis is substantially perpendicular to the first axis.
4. The lock mechanism as defined in claim 3 wherein the lock button is configured to rotate about a third axis, the third axis being generally parallel to the first axis.
5. The look mechanism as defined in claim 3 including stop means for preventing the lever assembly from rotating beyond a desired blocking position.
6. A door lock mechanism for a door comprising:
a door handle configured to be moved from a rest position to an activated position by a user thereof;
a first bias spring biasing the door handle to return to the rest position;
a lock button movable at least from an unlocked position to a locked position, wherein when the lock button Is in me locked position an associated door lock mechanism is locked thereby preventing the door from being opened at least from an exterior of a vehicle and wherein the lock button is configured such that when it is in an unlocked position the lock button is capable of being moved to its locked position by at least the operation of the door handle;
the lock mechanism and lock button being configured such that a release of the door handle under certain conditions from its activated position initiates movement of the lock button to its locked position;
the lock mechanism further includes a lever assembly for blocking the lock button from moving to the locked position of the lock button in response to a return movement of the door handle from its actuated position to its rest position
wherein the door handle is configured to rotate about a first axis and wherein the lever means is configured to rotate about a second axis, wherein the second axis is perpendicular to the first axis.
7. The lock mechanism as defined in claim 6 including stop means for preventing the lever assembly from rotating beyond a desired blocking position.
8. A door lock mechanism for a door comprising:
a door handle configured to be moved from a rest position to an activated position by a user thereof;
a first bias spring biasing the door handle to return to the rest position;
a lock button movable at least from an unlocked position to a locked position, wherein when the lock button is in the locked position an associated door lock mechanism is locked thereby preventing the door from being opened at least from an exterior of a vehicle and wherein the lock button is configured such that when it is in an unlocked position the lock button is capable of being moved to its locked position by at least the operation of the door handle;
the lock mechanism and lock button being configured such that a release of the door handle under certain conditions from its activated position initiates movement of the lock button to its locked position;
the lock mechanism further includes a lever assembly for blocking the lock button from moving to the locked position of the lock button in response to a return movement of the door handle from its actuated position to its rest position
including sequencing means for moving the lever assembly to a position remote from the lock button.
9. The lock mechanism as defined in claim 8 wherein the lever assembly sequencing means is configured to be moved to the remote position as the door handle returns to its rest position.
10. The lock mechanism as defined in claim 8 further including a lock button bias means for biasing the lock button toward the lock position.
11. The lock mechanism as defined in claim 10 including stop means for preventing the lever assembly from rotating beyond a desired blocking position.
12. The lock mechanism as defined in claim 8 including stop means for preventing the lever assembly from rotating beyond a desired blocking position.
