Vehicle door closer device
A vehicle door closer device comprises a latch that is capable of engaging with a striker of a vehicle body; a ratchet that is capable of engaging with the latch; and a release-canceling mechanism that comprises a first release-output lever, a second release-output lever and a canceling lever. A locking knob is operated, and the canceling lever disconnects a motion transmitting path between the first release-output lever and the second release-output lever thereby enabling the ratchet to engage with the latch, so that a vehicle door can be closed.
1. A vehicle door closer device comprising:
a latch that is capable of engaging with a striker;
a ratchet that is capable of engaging with the latch;
a motor;
a reduction mechanism which steps down rotation speed of the motor, motion by the motor being transmitted to the ratchet via the reduction mechanism and a motion-transmitting path to move the ratchet from an engagement position where the ratchet engages with the latch to a released position where the ratchet disengages from the latch, the reduction mechanism having a rotary member;
a release-canceling mechanism disconnecting the motion-transmitting path to enable the ratchet to return to the engagement position, the release-canceling mechanism comprising a first release-output lever configured to come in contact with the rotary member of the reduction mechanism to move the ratchet to the released position, a second release output lever connected to the ratchet directly or indirectly and a cancelling lever operable from a connected position connecting the motion-transmitting path and a disconnected position disconnecting the motion-transmitting path; and
a locking knob connected to the canceling lever,
wherein the second release-output lever can transmit the motion that comes from the reduction mechanism via the first release lever to the ratchet to move the ratchet to the released position when the canceling lever is in the connected position, and
wherein the locking knob is operated whereby the canceling lever disconnects the motion-transmitting path between the first release-output lever and the second release-output lever when the canceling lever is in the disconnected position.
2. The vehicle door closer device of claim 1 , further comprising a floating pin which moves with the canceling lever to the disconnected position to disconnect the motion-transmitting path between the first release-output lever and the second release-output lever.
3. The vehicle door closer device of claim 1 wherein the reduction mechanism comprises a planet gear mechanism.
4. The vehicle door closer device of claim 3 wherein the rotary member comprises a sun gear of the planetary gear mechanism.
5. The vehicle door closer device of claim 1 wherein the device is used in a sliding door.
6. A vehicle door closer device comprising:
a latch that is capable of engaging with a striker;
a ratchet that is capable of engaging with the latch;
a motor;
a reduction mechanism which steps down rotation speed of the motor, motion by a motor being transmitted to the ratchet via the reduction mechanism and a motion-transmitting path to move the ratchet from an engagement position where the ratchet engages with the latch to a released position where the ratchet disengages from the latch, the reduction mechanism having a rotary member;
a release-canceling mechanism disconnecting the motion-transmitting path to enable the ratchet to return to the engagement position, the release-canceling mechanism comprising a first release-output lever configured to come in contact with the rotary member of the reduction mechanism to move the ratchet to the released position, a second release output lever connected to the ratchet directly or indirectly and a cancelling lever operable from a connected position connecting the motion-transmitting path and a disconnected position disconnecting the motion-transmitting path, and
a moving member directly or indirectly connected to the canceling lever so that the moving member moves together with opening and closing of the door;
wherein the second release-output lever can transmit the motion that comes from the reduction mechanism via the first release lever to the ratchet to move the ratchet to the released position when the canceling lever is in the connected position, and
wherein the moving member is operated whereby the canceling lever disconnects the motion-transmitting path between the first release-output lever and the second release-output lever when the canceling lever is in the disconnected position.
7. The vehicle door closer device of claim 6 , further comprising a floating pin which moves with the canceling lever to the disconnected position to disconnect the motion-transmitting path between the first release-output lever and the second release-output lever.
8. The vehicle door closer device of claim 6 wherein the reduction mechanism comprises a planet gear mechanism.
9. The vehicle door closer device of claim 8 wherein the rotary member comprises a sun gear of the planetary gear mechanism.
10. The vehicle door closer device of claim 6 wherein the device is used in a sliding door.
