Other features and advantages of the invention will become apparent from the following detailed description for understanding the invention with reference to the accompanying drawings.

FIG. 1 represents an automobile door leaf 10 pivotally attached to a door frame 12 and shown in a door open position.

FIG. 2 includes a bolt 16 forming a latch and cooperating with a striker 18 attached to the door frame 12, a drive lever 20 of the bolt 16, and a blocking claw 22 of the bolt 16. The door closing device 14 shown in the above is equipped.

The door opening position shown in FIG. 2 corresponding to the door opening position of the door leaf 10, the door closing position called the door closing position in the first notch shown in FIG. 3 corresponding to the partially closing position of the door leaf 10, and the complete door leaf 10. In the second notch shown in FIG. 4, which corresponds to the door closing position, the bolt 16 can be pivotally moved around the lateral turning axis A to the fixed portion of the door leaf 10 called the frame, between the door closing position and the door closing position. It is attached to.

The bolt 16 defines a first stop notch 24 that cooperates with the claw 22 when the bolt 16 occupies a closed door position in the first notch.

Similarly, the bolt 16 defines a second stop notch 26 that cooperates with the claw 22 when the bolt 16 occupies a closed door position in the second notch.

In order to achieve this purpose, between the blocking position where the claw 22 opposes the turning of the bolt 16 from one of the closing positions to the opening position and the non-blocking position where the claw 22 releases the bolt 16. The claw 22 is pivotally attached to the frame around the horizontal axis B.

The claw 22 is elastically urged toward its blocking position by a return spring (not shown).

Further, in the case of door opening control, the claw 22 is pivoted to a driver 28 driven by an actuator (not shown) for releasing the latch so that the claw 22 can be driven to the non-blocking position of the bolt 16. It is fixed so that it can move.

The drive lever 20 of the bolt 16 is pivotally attached to the frame of the first section 30, the second section 34 connected to the drive cable 36, and the door leaf 10 forming the fork 32 for driving the bolt 16. It has a central section 38.

The fork 32 of the drive lever 20 includes a first branch 40 and a second branch 42.

The drive lever 20 is pivotally attached to the frame around the horizontal axis C.

Complementarily, the bolt 16 includes a finger 44 that normally extends radially with respect to the swivel axis A of the bolt 16, and when the bolt 16 moves from the open door position to the closed door position at the first notch, the bolt 16 forks. By pushing the first branch 40 of 32, the bolt 16 turns the drive lever 20 counterclockwise.

Therefore, when the bolt 16 occupies the closed door position in the first notch shown in FIG. 3, the finger 44 of the bolt 16 engages the fork 32.

Further, the second branch 42 of the fork 32 of the drive lever 20 is arranged so as to drive the bolt 16 from the closed position in the first notch to the closed position in the second notch via the finger 44.

The drive lever 20 is associated with a spring (not shown) that elastically biases the drive lever 20 in the clockwise direction.

On the contrary, the drive cable 36 extends from the output end 46 connected to the drive lever 20 of the bolt 16 to the input end 48 connected to the actuator 50 so that the drive lever 20 can turn counterclockwise. ing.

Therefore, by pulling the drive cable 36, the bolt 16 can be driven from the closed position in the first notch to the closed position in the second notch.

The assembly formed by the actuator 50, the drive cable 36, and the drive lever 20 of the bolt 16 constitutes a door leaf closing support device.

The actuator 50 is, for example, an assembly including a motor and a speed reducer, and can apply tension to the input end 48 of the drive cable 36.

Further, the door closing device 14 according to the present invention includes a clutch releasing member 52 forming a lever and a control element 54 of the clutch releasing member 52.

The clutch disengagement member 52 extends from a first portion 56 pivotally attached to the frame around the horizontal axis D to a first input sheath stop 60 or a second free portion 58 that supports the input sheath joint. There is.

The second output sheath stop portion 62 is attached to the actuator 50 fixed to the frame.

The curved sheath 64 accommodating the drive cable 36 extends between the first input sheath stop portion 60 and the second output sheath stop portion 62.

The clutch disengagement member 52 is designed to maintain the force transmission state shown in FIGS. 2 to 4 and the clutch disengagement state shown in FIG.

In the force transmission state, the clutch release member 52 is substantially prevented from pivoting on the frame, so that the drive cable 36 can transmit tension to the drive lever 20 to displacement drive the bolt 16. it can.

In the clutch release state, the clutch release member 52 can freely rotate with respect to the frame, and as a result, the first input sheath stop portion 60 is also in a free state. Therefore, the drive cable 36 cannot transmit sufficient tension to the drive lever 20 to displace the bolt 16.

Therefore, the clutch release member 52 has a force transmission position corresponding to the position taken by the clutch release member 52 in the force transmission state and a clutch release position corresponding to the position taken by the clutch release member 52 in the clutch release state at the end of the stroke. Between, it is pivotally attached to the frame.

The clutch release member 52 is elastically urged toward its transmission position by an elastic urging element (not shown).

Further, the door closing device 14 includes a joint 65 that is integral with the frame and is arranged to limit the stroke of the clutch release member at the force transmission position against the elastic urging element of the clutch release member. ..

In fact, when the input sheath stop and the output sheath stop are fixed to the wired sheath, the sheath receives a force proportional to the force transmitted by the drive cable at the position of the input sheath stop.

The force received by the sheath is distributed to each sheath stop by the path of the drive cable. This phenomenon applies only to non-linear or curved sheath pathways.

Conversely, if there is an input sheath stop fixed to a wired sheath and a free output sheath stop, the free output sheath stop is displaced by the action of the applied force and the force in the drive cable output. Is transmitted to the free output sheath stop so that the drive cable no longer transmits any force beyond the sheath.

The control element 54 is pivotally attached to the frame around the horizontal axis E.

Further, the control element 54 includes a blocking surface 66 that normally extends tangentially to the swivel axis E of the control element 54 and supports a support surface 68 formed on the clutch release member 52. There is.

To change the state of the clutch release member 52, the control element 54 is pivotally mounted between the blocking positions shown in FIGS. 2-4. Here, the blocking surface 66 of the control element 54 is in contact with the supporting surface 68 of the clutch releasing member 52.

In the non-blocking position shown in FIG. 5, the blocking surface 66 of the control element 54 is no longer facing the support surface 68 of the clutch releasing member 52 in order to release the clutch releasing member 52.

Further, the control element 54 has an arm 70 connected to a door opening transmission element (not shown) of the door leaf by, for example, a cable, so that when the door leaf is opened, the control element 54 is connected to the door leaf opening transmission element (not shown). It drives from its blocking position to its non-blocking position.

In fact, the control element 54 is connected to the claw 22 by a cable (not shown) so that the latch can be opened by releasing the bolt 16, and the control lever 54 is a different type of latch. It is urged throughout the opening, in particular the mechanical opening through the handle or the assistive opening through the gear motor.

In the operation example of the door closing device 14 according to the present invention, firstly, the door closing control supported by the actuator 50 without the request for priority door opening is supported by the actuator 50 interrupted by the priority door opening control. The closed door control that has been performed will be described below.

The actuator 50 is used to switch from the closed position in the first notch shown in FIG. 3 corresponding to the partially closed position of the door leaf 10 to the closed position in the second notch shown in FIG. 4 corresponding to the completely closed position of the door leaf 10. Apply tension to the drive cable 36. This force is transmitted to the drive lever 20 of the bolt 16 via the clutch release member 52 whose turning is blocked by the control element 54 that occupies the blocking position.

Note that in this configuration, when a force is applied by the drive cable 36, the clutch release member 52 turns toward the control element 54 and fills the gap J shown in FIG.

The gap J has a function of avoiding permanent friction between the clutch releasing member 52 and the control element 54, and the control element freely turns when the control element is swiveled to open the latch. It can be so.

Further, the gap J allows the control element 54 to return to the initial position without interfering with the clutch releasing member 52.

In the case of priority opening control, for example, when the user activates the handle of the door leaf 10 in the above-mentioned door closing support step in order to release the hand trapped in the door gap, the control element 54 moves from the blocking position to the non-blocking position. Drive up to.

Therefore, the control element 54 frees the "paused" clutch release member 52. As a result, when tension is applied to the drive cable 36 by the actuator 50, the sheath 64 contracts, the output sheath stop portion 60 transmits this force to the clutch release member 52, and the clutch release member 52 is shown in FIG. Turns and drives toward the clutch release position. Here, the drive lever 20 of the bolt 16 remains stationary.

Even when the door leaf closing support process is started, the door closing device 14 according to the present invention releases the clutch releasing member 52 to prevent the drive lever 20 of the bolt 16 from operating, thereby interrupting the door leaf closing support process. Please note that you can.

Opening a door takes precedence over closing a door.

Advantageously, the door closing device 14 according to the present invention does not require a specific clutch disengaging mechanism installed between the drive cable and the bolt.

The clutch release or clutch engagement of the clutch release member 52 uses a control lever 54, which is used in many types of latches to control the opening and closing of the door.

Therefore, the door closing device 14 according to the present invention has an advantage that only a single clutch releasing member 52 is required regardless of the presence or absence of a latch opening / closing request.

The embodiments of the present invention are described as non-limiting.

It should be understood that the clutch release lever can be pivotally and slidably attached to the frame.

Similarly, simply moving the mechanical components is included in the present invention, for example, the input sheath stop can be paused instead of the output sheath stop.

Finally, the door closing device according to the invention is suitable for all types of door leaf latches with cable closing control.
