[Industrial application fields]
The present invention relates to a door closer device that automatically closes a door in a non-complete (half) closed state to a full (full) closed state.
[0002]
[Prior art]
The complete (full) closed state of the vehicle side door is obtained by engaging a striker, which is a member on the vehicle side of the vehicle, with a latch that constitutes a part of a door lock device equipped on the side door. As shown in FIG. 6, the latch 1 is rotatable around the pin 2 and is always forced in one direction under the biasing force of the spring 3. The latch 1 includes an engagement groove 5 that receives the striker 4, a first claw portion 6 that is provided around the engagement groove 5 to create a door fully (full) closed state, and a second claw portion that creates a door incomplete (half) closed state. 7, and the protrusion 9 of the pole 8 can be freely engaged with both the claw portions 6 and 7.
[0003]
The pole 8 is rotatable around a pin 9 ′ and is always forced in the direction of the latch 1 by a spring 10. The pole 8 can be rotated counterclockwise by the movement of the pin 11 ′ of the open lift lever of the door lock device.
In the door open (open) state, the engagement groove 5 is directed rightward as viewed in FIG. 6, and the protrusion 9 of the pole 8 contacts the outer peripheral surface of the latch 1. When the door is closed, the striker 4 enters the engagement groove 5 to forcibly rotate the latch 1 counterclockwise, and the protrusion 9 engages with the second claw 7 to cause the door to be incomplete. A (half) closed state, that is, an incomplete (half) latched state, is created, and by further closing operation of the door, the protrusion 9 is engaged with the first claw portion 6, and the door is fully closed (that is, full) ) Create a latch state (state shown in FIG. 6).
[0004]
In the above-described door closing operation, when the operation force is weak, for example, the protrusion 9 of the pole 8 is engaged with the second claw portion 6 and the door is closed in an incomplete (half) closed state. May end. Therefore, a door in an incomplete (half) state is automatically closed using a door closer mechanism.
Examples of this type of door closer are disclosed in Japanese Patent Laid-Open Nos. 2-96079 and 6-50045.
[0005]
[Problems to be solved by the invention]
The door closer mechanism has a configuration in which a latch lever that rotates a rotating shaft of a latch is brought into contact with an active latch that is fixed to an active lever that is raised and lowered by an electric motor, and the latch lever is rotated according to the movement of the active latch. Is adopted. When an incomplete (half) closed state of the door is detected, the electric motor operates the active lever, and this movement is transmitted to the latch lever through the active latch, and the latch is incomplete as the latch lever rotates. It is automatically moved from a position corresponding to the (half) closed state (non-complete (half) latched state) to a position corresponding to the door fully (full) closed state (complete (full) latched state).
[0006]
However, sometimes, objects such as clothes and baggage are sandwiched between the door and the body during the door closing operation, and the door is changed from the open state to the incomplete (half) closed state. In this case, it is necessary to cancel the door closing operation by the door closer.
[0007]
Therefore, an object of the present invention is to solve the above-described cancellation reliably.
[0008]
[Means for Solving the Problems]
In the present invention, for the cancel operation described above, an active pawl or cancel lever that restricts the movement of the active latch in one direction is basically interposed between the active latch that can contact the latch lever and the active lever. And adopting a technical means for allowing the cancel lever to release the restriction of the one-way movement of the active latch.
Specifically, the present invention selects a first position where the door can be opened with respect to the vehicle body side member, a second position where the door is not fully closed, and a third position where the door is fully closed. A latch that takes one of the above, a pole that maintains any of the above-mentioned positions of the latch, an electric motor that operates by detecting the incompletely closed state of the door, an active lever that moves along a fixed linear locus by the output of the electric motor, An active latch that is rotatably supported, a cancel lever that is capable of restricting the rotation of the active latch in one direction and is rotatably supported by the active lever, and a free end that is fixed to the latch and faces the active latch and a latch lever, active latch by one-way rotation of active latch is restricted to take latches latch lever third position By the rotation of the cancel lever causes the urchin rotated to provide a latch of the latch lever by regulating the direction of rotation of the active latch is released door closing device for canceling the rotation that takes the third position.

DETAILED DESCRIPTION OF THE INVENTION
Please refer to FIG. 1 and FIG. The latch lever 12 is fixed to the pin 2 of the latch 1, the pin 9 ′ of the pole 8 is inserted into the mounting holes 14, 15 of the open lift lever 11 and the open lever 13 of the door lock device, and the pin 11 ′ of the lift lever 11 is mounted. Insert into the hole 16 of the pole 8. In response to the movement of the lift lever 11 that is operated in response to the opening / closing operation of the door, the pin 11 'rotates the pole 8 clockwise about the pin 9' (as viewed in FIG. 6). The contact with the claw portions 6 and 7 is released. That is, when the open lever 13 is rotatable in the A or B direction (door opening direction) and is rotated in the B direction in the example of FIG. 1, the lift lever 11 is rotated in the B direction, and the claw 17 is moved. Rotate in the C direction, push down the pin 11 ', then rotate the pole 8 in the D direction, release the protrusion 9 from the claw portions 6 and 7, and create an unlatched (latch release) state that allows the door to open.
[0010]
The free end of the latch lever 12 is opposed to the pawl 19 of the active latch 18 that has received the biasing force of the spring. The L-shaped active latch 18 is rotatably pinned with respect to the active lever 20, and causes the active lever 20, that is, the cancel lever 21 that receives the biasing force of the spring, to be pinned to the active lever 20. The active pole or cancel lever 21 is substantially V-shaped, and the first arm 22 is in contact with the free end 23 of the active latch 18 and has a long second arm 24. The contact between the free end 23 and the first arm 22 prevents the active latch 18 from rotating counterclockwise as viewed in FIG.
[0011]
After the door closing operation is completed, when the pole switch 25 (see FIG. 1) detects the door incomplete (half) closed state, the electric motor (M) operates, rotates its output lever 26, and turns the active lever 20 on. As shown in FIG. 2, it is moved downward. As a result, the pawl 19 of the active latch 18 abuts against the free end of the latch lever 12 and the latch lever 12 rotates in the direction E (as viewed in FIG. 2). ) Automatically move from latched position to full (full) latched position.
When the active latch 18 is brought into contact with the latch lever 12, the free end 23 of the active latch 18 comes into contact with the active pole, that is, the first arm 22 of the cancel lever 21, and the active latch 18 is counterclockwise (see FIG. 2). Therefore, the latch lever 12 can be turned in the E direction. The active latch 18 can be freely rotated in the clockwise direction.
[0012]
If the door is closed from the open state to the incomplete (half) closed state with an object such as clothes or baggage between the door and the body during the door closing operation, it is necessary to cancel the door closing operation by the door closer is there.
When an object is sandwiched between doors, when the door is opened by operating the handle, the intermediate lever 27 rotates counterclockwise as viewed in FIG. Therefore, the open lever 13 rotates in the F direction (corresponding to the B direction in FIG. 1), and the same operation as the door opening operation described in connection with FIG. 1 is obtained. This movement of the intermediate lever 27 causes the free end 28 of the intermediate lever 27 to abut against the second arm 24 of the active pole 21 and move the active pole 21 to the position indicated by the solid line in FIG. As a result, the engagement between the first arm 22 of the active pole 21 and the free end 23 of the active latch 18 is released, and the active latch 18 enters a free rotating state.
[0013]
Under such a state, when the pole switch 25 detects a door incomplete (half) closed state, the electric motor (M) pushes down the active lever 20 and the active latch 18 as described with reference to FIG. However, since the engagement between the first arm 22 of the active pole 21 and the free end 23 of the active latch 18 is released, the active latch 18 freely rotates even if the claw 19 abuts against the latch lever 12, There is no rotation of the latch lever 12. Thus, there is no transition from the incomplete (half) closed state of the door to the fully (full) closed state, and the door is opened.
[0014]
In the above-described operation, the free end of the latch lever 12 is positioned below the claw 19 of the active latch 18 as shown in FIG. 4, and the latch lever 12 is rotated or the active pole 21 is rotated counterclockwise. When this occurs, the active latch 18 can be rotated counterclockwise. However, when the door is opened during the canceling operation, sometimes the free latch of the latch lever 12 is positioned above the claw 19 in the positional relationship shown in FIG. In this case, by the door closing operation, the latch lever 12 is rotated counterclockwise by the latch 1, the claw 19 of the active latch 18 is brought into contact with the free end of the latch lever 12, and the active latch 18 is moved clockwise as viewed in FIG. 5. Rotate freely to obtain the normal state of FIG.
This abnormality avoidance can be obtained by allowing the active latch 18 to freely rotate clockwise as seen in FIGS.
In order to avoid this abnormal state, as shown in FIGS . 1 and 3 , a side surface that is a free end of the latch lever 12 and is in contact with the claw portion 19 of the active latch 18 is made an inclined surface 29. As shown in FIG. 5 , the latch lever 12 is rotated counterclockwise by the door closing operation described above to freely rotate the active latch 18, but the inclined surface 29 is in contact with both slips at the contact portion. The stroke is reduced, and the latch lever 12 can be quickly returned to the normal position.
