Description

The present invention relates to a door closer mechanism.

A mechanical mechanism generates switching power to switch the latch mechanism so that the door in the half-door state is automatically closed to the fully closed state, and the door is held in the half-door state to the fully closed state. There is a door closer mechanism that allows the door closer (for example, Patent Document 1).

In Patent Document 1, the switching power is stored in conjunction with the opening operation of the door, and the switching power is released in conjunction with the switching of the latch mechanism so as to hold the door in the half-door state with the closing operation of the door. A door closer mechanism provided with an assisting mechanism is disclosed. This assisting mechanism uses the elastic force of the coil spring as the switching power.

Specifically, the coil spring is compressed in conjunction with the opening operation of the door. When the door being opened reaches a certain degree of door opening, the coil spring is fixed in the compressed state until the latch mechanism is switched so as to hold the door in the half-door state.

Further, when the coil spring is fixed in the compressed state, the fixing of the coil spring is released in conjunction with the switching of the latch mechanism so as to hold the door in the half-door state. As a result, the coil spring is restored from the compressed state, and in conjunction with this restoration, the latch mechanism is switched so as to hold the door from the half-door state to the fully closed state. Therefore, the door in the half-door state is automatically closed until it is fully closed.

Special Fair 4-66982 Gazette

In the door closer mechanism described in Patent Document 1, when the coil spring is compressed, the compressed state of the coil spring cannot be fixed unless the door during the opening operation reaches a certain door opening degree or more. There is. In other words, before the door being opened reaches a certain door opening, even if the coil spring is compressed, it immediately tries to restore it, and the switching power stored by the compression of the coil spring closes the door. It may act to make it work.

The present invention has been made in view of such circumstances, and an object of the present invention is a door closer capable of suppressing the switching power stored in conjunction with the opening operation of the door from acting to close the door. It is to provide a mechanism.

The door closer mechanism that solves the above problems includes a first lever that rotates in conjunction with the opening / closing operation of the door, a second lever that rotates in conjunction with the first lever when pressed against the door, and a door. By elastically deforming in conjunction with the rotation of the second lever based on the opening operation, the latch mechanism is switched so as to hold the door from the half-door state to the fully closed state as the door closes. In conjunction with the switching of the latch mechanism and the elastic member that generates the switching power, which is the power for the purpose, from the opening operation of the door to the switching of the latch mechanism so as to hold the door in the half-door state. During that time, by engaging with the second lever, the elastic member is elastically deformed to store the switching power, while allowing the storage operation which is the operation of the second lever and restricting the return operation with respect to the storage operation. The operation of the second lever to release the stored switching power by disengaging the engagement with the second lever in conjunction with the switching of the latch mechanism so as to hold the door in the half-door state. A third lever that allows the release operation, and a fourth lever that operates in conjunction with the release operation of the second lever and transmits the stored switching power to the latch mechanism are provided. The first lever has a load applying structure that gives a change in load to the opening / closing operation when it rotates in conjunction with the opening / closing operation of the door.

According to the above configuration, when the second lever operates for storing power during the opening operation of the door, the return operation for the stored power operation is restricted. In this case, the return operation with respect to the power storage operation of the second lever is regulated regardless of the opening degree of the door during the opening operation. As a result, even if the door being opened is stopped in the middle while the switching power is stored, the second lever acts on the door being opened by returning the switching power stored up to that point. It can be held without causing it. Therefore, it is possible to prevent the switching power stored in conjunction with the opening operation of the door from acting to close the door.

In the case of this configuration, during the power storage operation, when the door is opened, a force for rotating the first lever (second lever), which is a force for elastically deforming the elastic member so as to store the switching power, is applied. It becomes possible to use it as a load acting on the door, that is, an operating force. Such a load acts as an axial torque at the center of rotation, which is a fulcrum of the first lever, in order to rotate the first lever. That is, as a load, the first lever presses the second lever from the elastic modulus of the elastic member, the arrangement of the first lever and the second lever, and the rotation centers of the first lever and the fulcrum of the second lever. A load of any magnitude can be set based on the ratio of each moment arm, which is the normal distance to the vector of the force acting on the site. As a result, the function of setting the load (operating force) to an arbitrary size can be added to the door closer mechanism.

Further, during the opening operation of the door, a change in load is given by the load applying structure of the first lever with respect to the opening operation, so that the load (operating force) can be set to an arbitrary size. It is possible to generate a sense of moderation in the opening operation of the door. This also applies when the door is closed. This makes it possible to add a function of generating a sense of moderation in the opening / closing operation of the door to the door closer mechanism. For example, when a door check mechanism is provided at the mounting destination of the door closer mechanism, the door check mechanism and the load applying structure of the first lever can be used together to freely design a sense of moderation in the opening / closing operation of the door. The degree can be increased. Further, even when the door check mechanism is not provided at the mounting destination of the door closer mechanism, the load applying structure of the first lever can generate a sense of moderation in the opening / closing operation of the door.

In the door closer mechanism for solving the above problems, the second lever is configured to slide on the first lever while the door is opened after storing the switching power by the storing force operation. Therefore, it is preferable that the load applying structure is formed by an uneven shape provided on a sliding portion which is a portion on the first lever on which the second lever slides.

According to the above configuration, after the switching power is stored by the power storage operation, the sliding resistance generated by the second lever sliding on the first lever is applied to the load when the door is opened, that is, It can be used as an operating force. Then, during the opening operation of the door, a change in the load is given by the uneven shape of the sliding portion of the first lever with respect to the opening operation. Therefore, the door opening operation is performed while the sliding resistance is applied. It is possible to preferably generate a feeling of moderation in. This also applies when the door is closed.

The door closer mechanism for solving the above problems further includes an initial position defining structure for defining the initial position where the door is the position of the first lever in the fully closed state, and the initial position defining structure is the door. It is preferable that the initial position can be adjusted so as to change the amount of rotation of the first lever until the load is changed based on the opening / closing operation of the lever.

According to the above configuration, for example, when the door is mounted on a vehicle, the amount of rotation of the first lever until the load is changed based on the opening / closing operation of the door is variable according to the vehicle model and specifications of the vehicle. Can be made to. That is, by adjusting the initial position of the first lever by the initial position defining structure, it is possible to correspond to a plurality of vehicle models and specifications, and the door closer mechanism can be applied among a plurality of vehicle models and specifications. Will be able to. In this case, it is effective in increasing the versatility of the door closer mechanism.

In the door closer mechanism for solving the above problems, it is preferable to further include a fully open position defining structure for defining the fully open position which is the position of the first lever when the door is in the fully open state.

According to the above configuration, a function as a stopper for stopping the door in the fully opened state can be added to the door closer mechanism. For example, when a door check mechanism is provided at the mounting destination of the door closer mechanism, the load generated when the door is stopped in the fully open state is distributed by using the door check mechanism and the fully open position defining structure together. The door check mechanism can be made smaller and lighter. Further, even when the door check mechanism is not provided at the mounting destination of the door closer mechanism, the door can be stopped in the fully open state by the fully open position defining structure.

In the door closer mechanism for solving the above problem, the fully open position defining structure can adjust the fully open position so that the amount of rotation of the first lever from the fully closed state to the fully open state of the door is variable. It is preferable that it is configured in.

According to the above configuration, for example, when the door is mounted on a vehicle, the amount of rotation of the first lever from the fully closed state to the fully open state of the door can be changed according to the vehicle model and specifications of the vehicle. .. That is, by adjusting the fully open position of the first lever by the fully open position defining structure, it is possible to correspond to a plurality of vehicle models and specifications, and the door closer mechanism can be applied among a plurality of vehicle models and specifications. Will be able to. In this case, it is effective in increasing the versatility of the door closer mechanism.

In the door closer mechanism for solving the above problems, the door is a vehicle door that opens and closes while being supported by the body of the vehicle, and the first lever rotates in conjunction with the opening and closing operation of the vehicle door. A check provided on the body of the vehicle and configured to be accessible to the inside of the vehicle door through a door check provided on the vehicle door may be connected via a cable. It is preferable that the lever is connected to the body of the vehicle via a cable so as to rotate in conjunction with the opening / closing operation of the vehicle door.

For example, when a check and a door check, that is, a door check mechanism is provided in the vehicle, a synergistic effect can be obtained by using the door check mechanism and the function of the door closer mechanism together as described above, and the vehicle door can be obtained. It is effective for improving the operability of the opening and closing operation of. Further, even when the check and the door check, that is, the door check mechanism is not provided in the vehicle, the same effect (function) as when the door check mechanism is provided can be obtained as described above. It is effective in reducing the number of parts while improving the operability of opening and closing the vehicle door.

According to the present invention, it is possible to prevent the switching power stored in conjunction with the opening operation of the door from acting to close the door.

(First Embodiment)
Hereinafter, the first embodiment of the door closer mechanism will be described.
As shown in FIG. 1, an opening 2a is provided on the side surface of the body 2 of the vehicle 1. A swing-type vehicle door (hereinafter referred to as “swing door”) 10 is provided in the opening 2a (in the fully closed state in FIG. 1). The swing door 10 is supported by the body 2 by a hinge 11 provided in front of the opening 2a in the front-rear direction L. In the swing door 10, a door operation unit 3 operated to open and close the swing door 10 is provided outside the inner / outer direction W. The swing door 10 opens and closes with respect to the vehicle 1 by operating the door operation unit 3 and rotating outward in the inward / outward direction W of the opening 2a with the hinge 11 as a fulcrum.

In the body 2, a long check 4 is connected to a region in the vicinity where the hinge 11 is provided. In check 4, the base end portion 4a on the body 2 side rotates in conjunction with the opening / closing operation of the swing door 10. Further, the check 4 is configured so as to be able to enter the inside of the swing door 10 through the door check 5 provided at the front end portion 10a of the swing door 10. The check 4 and the door check 5 constitute a door check mechanism DC having a function of generating a stepwise sense of moderation when the swing door 10 is opened and closed and a function of a stopper for stopping the swing door 10 in the fully opened state.

In the swing door 10, a door inner panel 12 is provided inside the inner / outer direction W. A door trim 12a is provided inside the door inner panel 12 in the inner / outer direction W. In the check 4, the door inner panel 12 swings around the base end portion 4a in conjunction with the opening / closing operation of the swing door 10 inside the door inner panel 12 on the side opposite to the side where the door trim 12a is provided. Inside the door check 5, it moves relative to the door check 5 in the longitudinal direction.

Specifically, when the swing door 10 is opened, the check 4 operates so as to escape from the inside of the door inner panel 12 through the door check 5. In this case, the tip end portion 4b, which is the opposite end portion of the base end portion 4a of the check 4, operates so as to approach the front end portion 10a of the swing door 10 in the direction of approaching the door check 5.

On the other hand, when the swing door 10 is closed, the check 4 operates so as to enter the inside of the door inner panel 12 through the door check 5. In this case, the tip portion 4b of the check 4 operates so as to approach the rear end portion 10b of the swing door 10 in the direction away from the door check 5.

As shown in FIG. 2, the check 4 is provided with a pair of upper and lower valley MDs (4c, 4d, 4e) when viewed from the inside / outside direction W (three in this embodiment). The valley portions 4c, 4d, and 4e are provided at predetermined intervals along the longitudinal direction of the check 4. By sandwiching any pair of valley MDs from above and below in the door check 5, the load changes when the check 4 enters or exits the swing door 10 through the door check 5 from the inside. A pair of giving rollers 5a are built in. As a result, in the door check mechanism DC, when the load is changed to the check 4 by the door check 5, the swing door 10 is slightly held so as to generate a gradual sense of moderation in the corresponding state (opening). Will be done.

As shown in FIGS. 1 and 2, the positional relationship between the check 4 and the door check 5 is such that when the door check 5 is closest to the base end portion 4a of the check 4, the swing door 10 is fully closed (fully closed). Opening (zero degree)). On the other hand, regarding the positional relationship between the check 4 and the door check 5, the check 4 is pulled out from the inside of the swing door 10 through the door check 5, and the valley portion 4c provided on the most proximal end portion 4a side of the check 4 is provided. When the roller 5a of the door check 5 sandwiches the door check 5, the swing door 10 is slightly held in the half-open 1 state (first stage opening hf1). Further, regarding the positional relationship between the check 4 and the door check 5, the check 4 further pulls out from the inside of the swing door 10 through the door check 5, and the valley 4d provided adjacent to the valley 4c of the check 4 is doord. When the roller 5a of the check 5 is sandwiched, the swing door 10 is slightly held in the half-open 2 state (second stage opening hf2). Then, as for the positional relationship between the check 4 and the door check 5, the check 4 pulls out from the inside of the swing door 10 through the door check 5, and the valley portion 4e provided on the most tip portion 4b side of the check 4 is the door check 5 When the roller 5a is sandwiched, the swing door 10 is slightly held in the fully opened state (fully opened opening degree fl). These are the same when the check 4 enters the inside of the swing door 10 through the door check 5.

The tip portion 4b of the check 4 is provided with a block-shaped end portion 4f that projects vertically with respect to the check 4 when viewed from the inside / outside direction W. When the roller 5a of the door check 5 sandwiches the valley portion 4e provided on the most tip portion 4b side of the check 4 into the end portion 4f, the door check 5 abuts on the inside of the swing door 10 beyond that. Restrict the movement of check 4 in the direction of pulling out from. As a result, in the door check mechanism DC, when the door check 5 restricts the movement of the check 4 in the direction of pulling out from the inside of the swing door 10, the swing door 10 is stopped in the fully open state (fully open opening fla). ..

Returning to the description of FIG. 1, the door lock device 13 is mounted inside the door inner panel 12 in addition to a regulator, a motor, glass, and the like related to a well-known power window device (not shown). The door lock device 13 includes a lock mechanism 14 and a door closer mechanism 15 which is an assist mechanism for applying switching power as power to the lock mechanism 14 (latch mechanism 20 described later). The lock mechanism 14 and the door closer mechanism 15 are located inside the door inner panel 12 in a direction orthogonal to the front-rear direction L along the panel rear end portion 12b, which is a portion of the swing door 10 on the rear end portion 10b side. They are arranged side by side in a certain vertical direction (in FIG. 1, the front and back directions of the paper surface). In particular, the door closer mechanism 15 is arranged on the lower side (in FIG. 1, behind the paper surface) with respect to the lock mechanism 14 in a manner of avoiding the regulator, the motor, the glass, etc. related to the power window device.

Inside the door inner panel 12, the check 4 and the door closer mechanism 15 are connected via a check cable C1, and the door closer mechanism 15 is configured to operate in conjunction with the opening / closing operation of the swing door 10. There is. Further, the lock mechanism 14 and the door closer mechanism 15 are connected via two cables, a release cable C2 and a close cable C3, and are configured to operate in conjunction with each other.

In the present embodiment, the door closer mechanism 15 is connected to the check 4 via the check cable C1. As a result, in the present embodiment, the door closer mechanism 15 operates in conjunction with the opening / closing operation of the swing door 10, and the lock mechanism 14 and the door closer mechanism 15 operate in conjunction with each other. It is completed only inside. That is, in the present embodiment, the mountability of the lock mechanism 14 and the door closer mechanism 15 is enhanced. The cables C1 to C3 are locked inside the door inner panel 12 by a clip or the like (not shown) so as not to interfere with the interlocking operation of the cables C1 to C3.

Next, the configuration of the lock mechanism 14 and the door closer mechanism 15 will be described in detail.
As shown in FIGS. 1 and 3, the locking mechanism 14 includes a latching mechanism 20 that engages (engages) with a striker 6 provided on the body 2 to hold the swing door 10 against the body 2. There is. The latch mechanism 20 operates based on the operation of the door operation unit 3, and when the door operation unit 3 is operated, the latch mechanism 20 is disengaged from the striker 6 and the swing door 10 is opened.

As shown in FIG. 3, the latch mechanism 20 includes a base plate 21 having a slit-shaped striker entry / exit groove 21a. A latch 22 that is rotatably supported, a pole 23 that is rotatably supported and regulates the rotation of the latch 22, and a lock lever 24 that rotates the latch 22 are attached to the base plate 21. .. The latch 22 and the pole 23 are attached at positions that sandwich the striker entry / exit groove 21a in the groove width direction (vertical direction in FIG. 3). The lock lever 24 is attached at a position opposite to the pole 23 sandwiching the latch 22.

The latch 22 has a substantially flat outer shape having a striker engaging groove 22a that opens on the outer peripheral surface thereof. Further, the latch 22 is rotationally urged in the counterclockwise direction in each drawing by a torsion coil spring (not shown). Further, the latch 22 rotates the latch 22 at a position (unlatch position) where the open end of the striker engagement groove 22a faces the striker entry / exit groove 21a by contacting a stopper portion (not shown) provided on the base plate 21. Rotation based on the urging force of the urging torsion coil spring is regulated. As a result, the latch mechanism 20 is configured such that the striker 6 that has entered the striker entry / exit groove 21a engages with the striker engagement groove 22a of the latch 22.

The pole 23 is rotationally urged in the clockwise direction in each drawing by a torsion coil spring (not shown). The pole 23 is provided with an engaging portion 23a that moves in a direction close to the outer peripheral surface of the latch 22 by rotation based on the urging force of the torsion coil spring that urges the pole 23 to rotate. The pole 23 is configured such that the engaging portion 23a engages with the outer peripheral surface of the latch 22 in a state where the striker 6 is engaged with the striker engaging groove 22a. As a result, the latch mechanism 20 can hold the state in which the striker 6 is engaged with the striker engagement groove 22a of the latch 22. In the present embodiment, the counterclockwise direction and the clockwise direction coincide with each other in the drawings. Therefore, in the following description, when indicating the rotation direction of various constituent members, it is simply described as "counterclockwise direction" or "clockwise direction".

More specifically, the striker 6 that has entered the striker inlet / outlet groove 21a from the unlatch position shown in FIG. 4A engages with the striker engagement groove 22a to press the latch 22 while inside the striker inlet / outlet groove 21a. Relatively moves toward the back side (from right side to left side in FIG. 4A). As a result, the latch 22 rotates in the clockwise direction against the urging force of the torsion coil spring that urges the latch 22 to rotate.

At this time, the engaging portion 23a of the pole 23 is apparently in contact with the latch 22 in a state of being pressed against the outer peripheral surface of the latch 22 based on the urging force of the torsion coil spring that rotationally urges the pole 23. It slides on the outer peripheral surface of 22. As a result, the rotation of the latch 22 is restricted by engaging the engaging portion 23a of the pole 23 with the first engaging portion 22b provided on the outer peripheral surface of the latch 22.

As shown in FIG. 4B, the first engaging portion 22b of the latch 22 is provided on the open end of the striker engaging groove 22a, that is, the side wall surface on the side where the striker 6 is pressed by engaging. There is. As a result, the striker 6 is attached to the latch 22 by restricting the rotation in the direction in which the striker 6 is discharged from the striker engagement groove 22a, which is the biasing direction by the torsion coil spring that rotationally biases the latch 22. It is configured to hold the engaged state. The state of the latch mechanism 20 at this time is the half-latch state, and the state of the swing door 10 at this time is the half-door state.

Returning to the description of FIG. 3, the lock lever 24 is rotationally urged in the clockwise direction by a torsion coil spring (not shown). The connection portion 24a of the lock lever 24 passes through the locking portion 21b provided on the base plate 21 and is conducted so as to wrap around the outer circumference of the lock lever 24 in the direction in which the lock lever 24 is rotationally urged. The tip C3a of the cable C3 is fixed by a screw or the like. When the close cable C3 is pulled, the lock lever 24 rotates in the counterclockwise direction against the torsion coil spring that urges the lock lever 24 to rotate. At this time, the lock lever 24 is configured to press the lever portion 22c provided on the outer peripheral surface of the latch 22 to switch the latch mechanism 20 to the full latch state (close operation).

That is, from the position corresponding to the half-latch state shown in FIG. 4B, the latch 22 resists the urging force of the torsion coil spring that rotates and urges the latch 22 by being pressed by the lock lever 24. Then, it is configured to rotate in the clockwise direction.

At this time, as shown in FIG. 4C, the engaging portion 23a of the pole 23 rotates the latch 22 by engaging with the second engaging portion 22d formed on the peripheral surface of the latch 22. It is configured to regulate the rotation of the latch 22 based on the urging force of the urging torsion coil spring. As a result, the striker engagement of the latch 22 is restricted by restricting the rotation in the direction in which the striker 6 is discharged from the striker engagement groove 22a, which is the biasing direction by the torsion coil spring that rotationally biases the latch 22. The striker 6 engaged with the groove 22a is constrained so as not to be relatively movable. The state of the latch mechanism 20 at this time is the full latch state, and the state of the swing door 10 at this time is the fully closed state.

Then, as shown in FIG. 3, the door closer mechanism 15 is configured to generate a switching power as a force for pulling in the closing cable C3, that is, a power for the lock lever 24 to perform the closing operation through the operation linked to the check cable C1. Has been done.

The tip C1a of the check cable C1 which is conducted through a clip (not shown) provided inside the door inner panel 12 is fixed to the end portion 4f (tip portion 4b) of the check 4 by a screw or the like. There is.

Further, the door closer mechanism 15 includes a regulation mechanism 17 that operates in conjunction with the state of the latch mechanism 20 by being connected to the latch 22 of the latch mechanism 20 via the release cable C2. As will be described in detail later, this embodiment comprises a release lever 34, which is a third lever that can mesh with the spring lever 32 of the power mechanism 16 and rotates in conjunction with the release cable C2 as the regulation mechanism 17. An example is shown. The tip C2a of the release cable C2, which is conducted through the locking portion 21b provided on the base plate 21, is fixed to the connecting portion 22e provided on the lever portion 22c of the latch 22 by a screw or the like.

Further, the door closer mechanism 15 operates in conjunction with the power mechanism 16 and the regulation mechanism 17, and operates so as to transmit the operation to the lock lever 24 of the latch mechanism 20 connected via the close cable C3. A transmission mechanism 18 is provided.

Specifically, as shown in FIGS. 5 and 6, the door closer mechanism 15 includes a mounting base 30 having a mounting surface 30a for mounting various components. A check lever 31 is rotatably attached to the attachment surface 30a via a support member 41.

Further, the spring lever 32 is rotatably attached to the mounting surface 30a via the support member 42 so as to have a rotating track that overlaps a part of the rotating track of the check lever 31.

Further, a mounting base 30 is sandwiched between the mounting back surface 30b on the back side of the mounting surface 30a and the spring lever 32, and one end on the outer peripheral side is fixed to the mounting base 30 and one end on the inner peripheral side is fixed to the support member 42. In this state, a spiral spring (so-called spiral spring) 33 is attached.

Further, the release lever 34 is rotatably attached to the attachment surface 30a via the support member 44 so as to have a rotation trajectory that overlaps a part of the rotation trajectory of the spring lever 32.

Further, a passive lever 35 is attached to the attachment surface 30a via a spring lever 32. That is, the passive lever 35 is rotatably attached to the spring lever 32 via the support member 45.

Further, the latch lever 36 is rotatably attached to the attachment surface 30a via the support member 46 so as to have a rotation trajectory that overlaps a part of the rotation trajectory of the passive lever 35.
The check lever 31 is rotationally urged in the counterclockwise direction by the torsion coil spring 51 fitted into the support member 41. The check lever 31 is provided with a cable groove 31a having a depth in the radial direction thereof. The cable groove 31a is continuously provided in a part of the outer peripheral surface of the check lever 31 in the circumferential direction. The check cable C1 is conducted through the cable groove 31a.

The check cable C1 passes through the locking portion 30c provided on the mounting base 30 and is conducted so as to wrap around the outer circumference of the check lever 31 in the direction in which the check lever 31 is rotationally urged. The check cable C1 has a connection portion 31b provided at the end where the other end C1b (the end opposite to the tip C1a connected to the end portion 4f of the check 4) wraps around the outer circumference of the check lever 31 by a screw or the like. It is fixed. When the check cable C1 is pulled, the check lever 31 rotates clockwise against the urging force based on the torsion coil spring 51. At this time, the check lever 31 is rotated by the pressing portion 31c provided so as to face the connecting portion 31b in its circumferential direction by pressing the spring lever 32 on which the rotation trajectories partially overlap.

The sliding portion 31d is provided with a plurality of recesses md (31e, 31f) having recesses inside the check lever 31 in the radial direction (two in the present embodiment). The recesses 31e and 31f are provided at predetermined intervals along the circumferential direction of the sliding portion 31d. Among the valley MDs provided in the check 4, the predetermined intervals are the valley 4c provided on the most proximal end 4a side of the check 4 and the valley 4d provided adjacent to the valley 4c. It matches the predetermined interval with.

In the check lever 31, the initial contact portion 31g provided on the opposite side of the pressing portion 31c in the circumferential direction abuts on the positioning portion Sa provided on the mounting base 30 so as to project toward the mounting surface 30a. As a result, the rotation of the torsion coil spring 51 based on the urging force is regulated. When the swing door 10 is fully closed, the initial contact portion 31g comes into contact with the positioning portion Sa to restrict the rotation of the check lever 31 based on the further urging force of the torsion coil spring 51. To do. The position of the check lever 31 in this case is defined as the initial position when the swing door 10 is fully closed. That is, the position defining unit Sa constitutes an initial position defining structure SR that defines the initial position of the check lever 31.

In the present embodiment, the position defining portion Sa moves in the through hole Sb provided so as to extend along the rotation trajectory in a state of overlapping the rotation trajectory of the check lever 31, thereby causing the check lever 31 to move. The initial position of is adjustable. This adjustment is performed by varying the position of the position defining portion Sa in the through hole Sb, for example, by providing an adjusting screw (adjusting screw) on the mounting back surface 30b. As a result, the amount of rotation of the check lever 31 until the spring lever 32 sliding on the sliding portion 31d reaches the recess md (31e, 31f) based on the opening / closing operation of the swing door 10 can be changed. .. When the check lever 31 is in the initial position, the door check 5 has the maximum amount of rotation until the spring lever 32 reaches the recess 31e provided on the pressing portion 31c side of the check lever 31 with respect to the base end portion 4a of the check 4. It coincides with the interval from the close state until the roller 5a of the door check 5 sandwiches the valley portion 4c provided on the most proximal end portion 4a side of the check 4. Further, when the check lever 31 is in the initial position, the amount of rotation until the spring lever 32 reaches the recess 31f provided adjacent to the recess 31e of the check lever 31 is door checked with respect to the base end portion 4a of the check 4. It coincides with the interval from the state in which 5 is closest to the time when the roller 5a of the door check 5 sandwiches the valley portion 4d provided adjacent to the valley portion 4c of the check 4.

Further, the check lever 31 is provided on the mounting base 30 so that the fully open contact portion 31h provided so as to protrude outward in the radial direction in the vicinity of the connecting portion 31b in the circumferential direction protrudes toward the mounting surface 30a. The rotation of the torsion coil spring 51 against the urging force is regulated by abutting against the position defining portion Ea. When the swing door 10 is in the fully open state, the fully open contact portion 31h abuts on the position defining portion Ea to restrict the rotation of the check lever 31 against the further urging force of the torsion coil spring 51. To do. The position of the check lever 31 in this case is defined as the fully open position when the swing door 10 is fully open. That is, the position defining unit Ea constitutes a fully open position defining structure ER that defines the fully open position of the check lever 31.

In the present embodiment, the position defining portion Ea moves in the through hole Eb provided so as to extend along the rotating track in a state adjacent to the rotating track of the check lever 31, thereby moving the check lever 31. It is configured so that the fully open position of is adjustable. This adjustment is performed by varying the position of the position defining portion Ea in the through hole Eb, for example, by providing an adjusting screw (adjusting screw) on the mounting back surface 30b. As a result, the amount of rotation of the check lever 31 from the fully closed state to the fully open state of the swing door 10 can be changed. When the check lever 31 is in the initial position, the amount of rotation to the fully open position is the valley portion provided on the most tip portion 4b side of the check 4 from the state where the door check 5 is closest to the base end portion 4a of the check 4. It coincides with the interval until the roller 5a of the door check 5 sandwiches the 4e, that is, until the door check 5 comes into contact with the end portion 4f of the check 4.

Further, the spring lever 32 is configured so that the support member 42 rotates integrally when rotating on the mounting surface 30a, and one end on the inner peripheral side is fixed to the support member 42. It is rotationally urged in the clockwise direction by the spiral spring 33.

The spring lever 32 is provided with a gear portion 32a extending in a fan shape from substantially the center thereof. On the outer peripheral surface of the gear portion 32a, teeth 32b to which the release lever 34 can be engaged are provided. When the spring lever 32 tries to rotate in the clockwise direction due to the urging force of the spiral spring 33, the teeth 32b are rotated by the release lever 34, which partially overlaps the rotation trajectories, meshing with the release lever 34. It is tilted in a predetermined direction so that the movement is regulated. In this predetermined direction, when the spring lever 32 tries to rotate in the counterclockwise direction against the urging force based on the spiral spring 33, even if the release lever 34 whose rotation trajectories partially overlap is engaged, the release is concerned. This is the direction in which the lever 34 can get over the teeth 32b. The teeth 32b are provided on the outer peripheral surface of the gear portion 32a so as to have a range larger than the range (rotation amount) in which the rotation trajectories of the check lever 31 and the spring lever 32 overlap.

Further, the spring lever 32 is provided with an arm portion 32c extending from substantially the center thereof toward the check lever 31 side in a direction different from that of the gear portion 32a. At the tip of the arm portion 32c, a pressed portion 32d protruding from a surface opposite to the mounting surface 30a is provided. The pressed portion 32d is a portion pressed by the pressing portion 31c of the check lever 31 on which the rotation trajectories partially overlap. When the pressed portion 32d is pressed, the spring lever 32 rotates in the counterclockwise direction against the urging force based on the spiral spring 33. At this time, the spring lever 32 is elastically deformed so as to wind up the spiral spring 33 and bend (shrink) in the radial direction by rotating the support member 42, and after being deformed by a predetermined amount, the pressed portion 32d Is configured to slide on the sliding portion 31d of the check lever 31.

Further, the release lever 34 is rotationally urged in the counterclockwise direction by the torsion coil spring 54 fitted in the support member 44. The release lever 34 is provided with a claw-shaped pawl portion 34a as a meshing portion that can mesh with the gear portion 32a of the spring lever 32. The pawl portion 34a meshes with the gear portion 32a in which the rotation trajectories partially overlap by the urging force based on the torsion coil spring 54, so that the spring lever 32 rotates in the clockwise direction. In this case, the rotation is restricted by biting into the tooth 32b. On the other hand, when the spring lever 32 tries to rotate counterclockwise, the pawl portion 34a is allowed to rotate over the teeth 32b. That is, the gear portion 32a and the pawl portion 34a mesh with each other to allow the spring lever 32 to rotate in one direction (counterclockwise direction), and in the opposite direction (clockwise direction). It constitutes a ratchet mechanism RS that regulates rotation to the gear.

In the release lever 34, the other end C2b of the release cable C2 (which is conducted to the connecting portion 34b provided at the end opposite to the pawl portion 34a through the locking portion 30d provided on the mounting base 30) The tip on the opposite side of the tip C2a connected to the lever portion 22c of the latch 22) is fixed by a screw or the like. When the release cable C2 is pulled, the release lever 34 rotates clockwise against the urging force based on the torsion coil spring 54. As a result, the pawl portion 34a is disengaged from the gear portion 32a on which the rotation trajectories partially overlap so as to disengage, and the restriction on the clockwise rotation of the spring lever 32 is released.

Further, the passive lever 35 is attached to a lever mounting portion 32e extending in a direction different from the gear portion 32a and the arm portion 32c from substantially the center of the spring lever 32 so that it can rotate integrally with the spring lever 32. There is. The passive lever 35 is rotationally urged in the counterclockwise direction by a torsion coil spring 55 fitted in the support member 45. The passive lever 35 abuts on the regulation piece 32f provided at the base end of the arm portion 32c of the spring lever 32, so that the rotation based on the urging force of the torsion coil spring 55 is restricted. .. By rotating integrally with the spring lever 32, the passive lever 35 has a pressing piece 35a provided so as to extend in a piece shape from the surface opposite to the mounting surface 30a, and the rotation trajectory is set. It is configured to press and rotate the partially overlapping latch lever 36.

Further, the latch lever 36 is rotationally urged in the clockwise direction by a closed cable C3 connected to a connecting portion 36a provided at a position separated from a portion supported by the supporting member 46. At the connecting portion 36a, the other end C3b (the tip on the opposite side of the tip C3a connected to the lock lever 24) of the closed cable C3 which is conducted through the locking portion 30e provided on the mounting base 30 is screwed or the like. Is fixed by.

The latch lever 36 is provided with a protruding portion 36b protruding from a surface opposite to the mounting surface 30a. The protruding portion 36b is provided at a portion different from the connecting portion 36a in a state of being separated from the portion supported by the support member 46. The protruding portion 36b is a portion pressed by the pressing piece 35a of the passive lever 35 on which the rotation trajectories partially overlap. When the protrusion 36b is pressed, the latch lever 36 rotates counterclockwise against the pulling force of the closed cable C3. At this time, the latch lever 36 is configured to rotate the lock lever 24 of the latch mechanism 20 in the counterclockwise direction by pulling in the close cable C3.

Next, the operation of the door lock device 13 linked to the opening / closing operation of the swing door 10 will be described focusing on the operations of the latch mechanism 20 and the door closer mechanism 15.
The state shown in FIG. 7A is the fully closed state of the swing door 10, that is, the initial state of the door closer mechanism 15 in the fully latched state of the latch mechanism 20 (the state shown in FIGS. 3 and 4C). Check 4 is a state in which the tip portion 4b enters the inside of the door inner panel 12 most, and the tip portion 4b enters the inner part of the inside of the door inner panel 12 (rearward in the front-rear direction L) most.

Specifically, the check cable C1 is not pulled by the check 4, and the check lever 31 is rotationally urged in the counterclockwise direction by the urging force of the torsion coil spring 51 to make initial contact. This is the initial position where the portion 31g abuts on the positioning portion Sa. That is, the spring lever 32 is not pressed by the check lever 31 (the pressing portion 31c and the pressed portion 32d are in light contact (or no contact)), and the spring lever 32 is the urging force of the spiral spring 33. Therefore, it is in a state of being rotationally urged in the clockwise direction. The spiral spring 33 is in a state where the amount of bending deformation in the radial direction is minimal (or zero). Further, the release cable C2 is pulled by the latch 22, and the release lever 34 is rotationally urged in the clockwise direction against the urging force based on the torsion coil spring 54. .. The passive lever 35 is in a state of being in contact with the regulation piece 32f, and is in a state of being rotationally urged in the counterclockwise direction by the urging force of the torsion coil spring 55. Further, the closed cable C3 is pulled by the lock lever 24, and the latch lever 36 is rotationally urged in the clockwise direction by the closed cable C3.

Subsequently, when the latch mechanism 20 disengages from the striker 6 based on the operation of the door operating unit 3 (state shown in FIG. 4A) and the swing door 10 is opened, the swing door 10 is opened. The front end portion 4b of the check 4 operates so as to move away from the rear end portion 10b of the swing door 10, that is, the door closer mechanism 15, according to the opening degree of the check 4.

That is, in FIG. 7A, as shown by the arrow A, the check cable C1 is pulled by the check 4 in conjunction with the swing door 10 being opened from the fully closed state. In the latch mechanism 20, the latch 22 is switched to the unlatch position by rotating the latch 22 in the counterclockwise direction from the position in the full latch state. In conjunction with this, the release cable C2 is loosened by the latch 22. The state in which the closed cable C3 is pulled by the lock lever 24 is maintained.

Similarly, as indicated by the arrow A, the release lever 34 is rotated counterclockwise by the urging force of the torsion coil spring 54 in conjunction with the loosening of the release cable C2, and the pawl portion 34a is moved. It operates so as to mesh with the gear portion 32a (tooth portion 32b) located on the rotary track RT4.

Similarly, as indicated by the arrow A, in conjunction with the check cable C1 being pulled by the check 4, the check lever 31 rotates clockwise against the urging force based on the torsion coil spring 51. .. As a result, the pressing portion 31c operates so as to press the pressed portion 32d located on the rotation track RT1. In conjunction with this, the spring lever 32 rotates counterclockwise against the urging force based on the spiral spring 33 while pushing away the pawl portion 34a located on the rotation trajectory RT2 by the gear portion 32a. To do. On the other hand, in the spring lever 32, the pawl portion 34a located on the rotation track RT2 bites into the gear portion 32a, and the rotation in the clockwise direction due to the urging force of the spiral spring 33 is restricted. In conjunction with this, the release lever 34 repeats the operation of the pawl portion 34a moving back and forth between the rotation orbits RT4 along the outer circumference of the gear portion 32a.

The spiral spring 33 elastically deforms so as to bend in the radial direction in conjunction with the rotation of the spring lever 32 in the counterclockwise direction. In conjunction with the increase in the amount of rotation of the spring lever 32, the spiral spring 33 elastically deforms so as to increase the amount of deflection in the radial direction, that is, to increase the elastic force. This elastic force serves as a switching power, and the spiral spring 33 is configured to increase the elastic force and store the switching power by elastically deforming so as to increase the amount of deflection in the radial direction. At this time, since the rotation of the spring lever 32 in the clockwise direction is restricted, the spiral spring 33 is restricted from being restored (returned) from the state of being bent in the radial direction.

In this way, in conjunction with the pulling of the check cable C1 by the check 4, the spring lever 32 operates to store the switching power so as to store the switching power. During the power storage operation, the release lever 34 operates in conjunction with the loosening of the release cable C2, so that the spring lever 32 operates so as to restore the spiral spring 33 from the bent state. The return movement to is regulated.

In the present embodiment, the force for rotating the check lever 31 (spring lever 32), which is the force for storing the switching power, acts as a load for opening the swing door 10, that is, an operating force. This load acts as a shaft torque of the support member 41 which is the center of rotation of the check lever 31. This shaft torque is proportional to the shaft torque based on the elastic modulus of the spiral spring 33 acting on the support member 42 which is the center of rotation of the spring lever 32 when the spiral spring 33 is flexed in the radial direction.

Specifically, as shown in FIG. 7A, when the force acting on the pressing portion 31c of the check lever 31 (the pressed portion 32d of the spring lever 32) is represented by the force vector V, the check lever 31 and the spring lever Each moment arm, which is the length of the normal to the force vector V at 32, can be represented by the arm lengths ra and rb. In this case, the load is the shaft torque obtained by multiplying the shaft torque acting on the support member 42 by the ratio (ra / rb) of the arm length rb to the arm length ra. The direction and size of the force vector V changes according to the arrangement of the check lever 31 and the spring lever 32 (for example, the set angle).

In FIG. 7A, as shown by an arrow A, the passive lever 35 rotates integrally with the spring lever 32 in conjunction with the rotation of the spring lever 32 in the counterclockwise direction. At this time, the pressing piece 35a comes into contact with the protruding portion 36b located on the rotating track RT5, but the passive lever 35 rotates clockwise against the urging force based on the torsion coil spring 55. It passes while (rotating relative to the spring lever 32). This is because the urging force based on the torsion coil spring 55 that rotates and urges the lock lever 24 is set larger than the urging force based on the torsion coil spring 55. After the pressing piece 35a passes through the protruding portion 36b located on the rotating track RT5, the passive lever 35 is in contact with the regulation piece 32f, and is counterclockwise due to the urging force of the torsion coil spring 55. It returns to the state of being urged to rotate in the direction.

Subsequently, as shown in FIG. 7B, when the opening degree of the swing door 10 during the opening operation reaches a certain level or more, the pressed portion 32d does not exist on the rotation trajectory RT1 of the pressing portion 31c. The check lever 31 swings the spring lever 32 and cannot press it. The opening degree above a certain level is set at a relatively early stage of the opening operation of the swing door 10, and the swing door 10 is fully opened before the first stage opening hf1 in the half-opened 1 state. The opening is sufficiently small compared to the opening at the time.

As shown by the arrow B in FIG. 7B, the check lever 31 is urged based on the torsion coil spring 51 in conjunction with the swing door 10 being further opened from the front of the half-open 1 state. It rotates clockwise against the counterclockwise direction. At this time, the spring lever 32 slides on the sliding portion 31d via the pressed portion 32d. That is, the check lever 31 rotates in the clockwise direction against the sliding resistance generated between the sliding portion 31d and the pressed portion 32d.

On the other hand, regardless of the rotation of the check lever 31, the spring lever 32 is maintained in a state in which the release lever 34 regulates the clockwise rotation due to the urging force of the spiral spring 33. At this time, the spiral spring 33 is in the most flexed state in the radial direction, and the state in which restoration from the bent state is restricted is maintained.

In this way, when the check lever 31 swings the spring lever 32 and cannot press the spring lever 32 in conjunction with the pulling of the check cable C1 by the check 4, the spring lever 32 is configured to complete the storage of the switching power. ing.

Then, as shown in FIG. 8A, the check lever 31 resists the urging force based on the torsion coil spring 51 in conjunction with the swing door 10 being opened to the half-open 1 state. Rotate clockwise. At this time, the load when the check lever 31 rotates clockwise or counterclockwise by fitting the pressed portion 32d into the recess 31e provided on the pressing portion 31c side on the sliding portion 31d. Change will be given. When the pressed portion 32d is fitted into the recess 31e, the swing door 10 is slightly held in the half-open 1 state (first step opening hf1). This is the same even when the pressed portion 32d is fitted into the recess 31e by closing the swing door 10. Then, as shown by the arrow C, in conjunction with the swing door 10 being further opened from the half-open 1 state, the check lever 31 resists the load applied by the pressed portion 32d being fitted into the recess 31e. Then, it rotates clockwise.

Subsequently, when the swing door 10 is opened to the half-open 2 state, the check lever 31 is clocked by fitting the pressed portion 32d into the recess 31f provided adjacent to the recess 31e on the sliding portion 31d. A change in load is given when rotating in a clockwise direction or a counterclockwise direction. When the pressed portion 32d is fitted into the recess 31f, the swing door 10 is slightly held in the half-open 2 state (2 cross-sectional opening hf2). This is the same even when the pressed portion 32d is fitted into the recess 31f by closing the swing door 10. Then, in conjunction with the swing door 10 being further opened from the half-open 2 state, the check lever 31 clockwise counterclockwise against the load applied by the pressed portion 32d being fitted into the recess 31e. Rotate.

As a result, when the load is changed to the check lever 31 (spring lever 32) by the load applying structure LG, the swing door 10 is slightly adjusted to generate a gradual sense of moderation in the corresponding state (opening). Is held in.

After that, as shown in FIG. 8B, when the swing door 10 is opened to the fully opened state, the check lever 31 resists the urging force based on the torsion coil spring 51 in conjunction with the opening operation. Then, the fully open contact portion 31h rotates clockwise until it comes into contact with the position defining portion Ea.

Subsequently, as shown by an arrow D in FIG. 8B, when the swing door 10 is closed from the fully open state, the tip portion 4b of the check 4 is moved to the swing door 10 according to the opening degree of the swing door 10. It operates so as to approach the rear end portion 10b, that is, the door closer mechanism 15. That is, the check cable C1 is loosened by the check 4. In conjunction with this, the check lever 31 rotates in the counterclockwise direction by the urging force of the torsion coil spring 51.

Then, the latch mechanism 20 engages with the striker 6 (the state shown in FIG. 4B), and the latch 22 rotates clockwise from the unlatch position to switch the latch 22 to the half-latch state position. .. That is, the release cable C2 is pulled by the latch 22. At this time, the swing door 10 is closed to the half-door state.

As shown by the arrow D in FIG. 8B, the release lever 34 rotates clockwise against the urging force of the torsion coil spring 54 in conjunction with the pulling of the release cable C2 by the latch 22. Rotate in the direction. As a result, the pawl portion 34a is separated from the gear portion 32a (tooth portion 32b) located on the rotation track RT4. In conjunction with this, the spiral spring 33 starts the restoration from the state of being bent in the radial direction, thereby elastically deforming so as to be bent in the radial direction, and releases the switching power stored (held). In conjunction with this, the spring lever 32 and the passive lever 35 rotate integrally in the clockwise direction. As a result, the pressing piece 35a comes into contact with the protruding portion 36b located on the rotating track RT5.

In this way, in conjunction with the pulling of the release cable C2 by the latch 22, the spring lever 32 releases the stored switching power so as to release it.
That is, as shown in FIG. 9A, when the swing door 10 is closed to the half-door state, the check lever 31 is moved by the urging force of the torsion coil spring 51 in conjunction with the closing operation. The initial contact portion 31g rotates counterclockwise to the initial position where the initial contact portion 31g abuts on the positioning portion Sa. At this time, in conjunction with the release operation of the spring lever 32, the pressing piece 35a is restricted from rotating based on the urging force of the torsion coil spring 55 by the passive lever 35 coming into contact with the regulation piece 32f. In this state, the protruding portion 36b located on the rotating track RT5 is pressed.

As shown by the arrow E in FIG. 9A, the latch lever 36 counterclockwise against the force of pulling the closed cable C3 by the lock lever 24 in conjunction with the pressing of the protruding portion 36b. It rotates in the clockwise direction. That is, the latch lever 36 pulls in the closed cable C3. This is because, as the spiral spring 33, the elastic force in the most flexed state in the radial direction is set to be larger than the urging force based on the torsion coil spring that rotationally urges the lock lever 24. Is the reason.

Similarly, as indicated by the arrow E, in conjunction with the latch lever 36 pulling in the closed cable C3, the lock lever 24 counterclockwise against the urging force of the torsion coil spring that urges the latch lever 36 to rotate. It rotates in the clockwise direction and presses the lever portion 22c of the latch 22. In conjunction with this, the latch 22 rotates clockwise to switch from the half-latch state position to the full-latch state position. That is, the latch mechanism 20 is switched to the full latch state, and the swing door 10 is automatically fully closed.

In this way, in conjunction with the release operation of the spring lever 32, the passive lever 35 and the latch lever 36 transmit the switching power stored by the spring lever 32 in the storage operation to the latch mechanism 20. Operate.

After that, as shown by the arrow F in FIG. 9B, the protruding portion 36b does not exist on the rotation trajectory RT5 of the pressing piece 35a, and the passive lever 35 swings the latch lever 36 and cannot press it. In conjunction with this, the lock lever 24 rotates clockwise due to the urging force of the torsion coil spring that urges the lock lever 24 to rotate. That is, the lock lever 24 pulls the closed cable C3. In conjunction with this, the latch lever 36 rotates in the clockwise direction. That is, the door closer mechanism 15 is in the initial state.

According to the present embodiment described above, the following effects are obtained.
(1) According to the present embodiment, when the spring lever 32 performs the accumulating operation during the opening operation of the swing door 10, the return operation with respect to the accumulating operation is restricted. In this case, the return operation of the spring lever 32 with respect to the storage operation is regulated regardless of the opening degree of the swing door 10 during the opening operation.

For example, if the swing door 10 in the open operation is stopped in the middle, the check cable C1 is not pulled by the check 4. At this time, the release lever 34 operates so as to mesh with the spring lever 32, so that the spring lever 32 rotates in the clockwise direction, that is, the spiral spring 33 is restored (returned) from the radial direction. Operation is regulated.

As a result, even if the swing door 10 in the open operation is stopped in the middle of the spring lever 32 in the state where the switching power is stored, the switching power stored up to that point is returned to the swing in the open operation. It can be held without acting on the door 10. Therefore, it is possible to prevent the switching power stored in conjunction with the opening operation of the swing door 10 from acting to close the swing door 10.

In the case of this configuration, during the power storage operation, the force for rotating the check lever 31 (spring lever 32), which is the force for flexing the spiral spring 33 in the radial direction so as to store the switching power, is applied to the swing door 10. Can be used as a load for opening the door, that is, as an operating force. Such a load acts as a shaft torque of the support member 41 of the check lever 31. That is, as a load, a force of an arbitrary magnitude is set based on the elastic modulus of the spiral spring 33, the arrangement of the check lever 31 and the spring lever 32, and the ratio of the respective moment arms of the check lever 31 and the spring lever 32. can do. As a result, the function of setting the load (operating force) to an arbitrary size can be added to the door closer mechanism 15.

Further, during the opening operation of the swing door 10, a change in the load is given by the load applying structure LG (recessed md) of the check lever 31 with respect to the opening operation, so that the load (operating force) can be adjusted to the above-mentioned arbitrary size. In the setting, it is possible to generate a sense of moderation in the opening operation of the swing door 10. This also applies when the swing door 10 is closed. As a result, the function of generating a sense of moderation in the opening / closing operation of the swing door 10 can be added to the door closer mechanism 15. Therefore, when the door check mechanism DC is provided in the vehicle 1 as in the present embodiment, the swing door 10 can be opened and closed by using the door check mechanism DC and the load applying structure LG of the check lever 31 together. It is possible to increase the degree of freedom in designing a sense of moderation in operation.

(2) In the present embodiment, when increasing the load for opening the swing door 10, for example, the arm length rb, which is the moment arm of the spring lever 32, can be set short. As a synergistic effect in this case, the door closer mechanism 15 can be configured so that the check lever 31 and the spring lever 32 are arranged closer to each other, which is effective in reducing the size of the door closer mechanism 15.

(3) In the present embodiment, after the switching power is stored by the accumulating operation of the spring lever 32, the pressed portion 32d of the spring lever 32 slides on the sliding portion 31d of the check lever 31. The dynamic resistance can be used as a load for opening the swing door 10, that is, an operating force. Then, during the opening operation of the swing door 10, a change in load is given by the uneven shape (recessed md) of the sliding portion 31d of the check lever 31 with respect to the opening operation, so that the sliding resistance is applied. Among them, a feeling of moderation in the opening operation of the swing door 10 can be preferably generated. This also applies when the swing door 10 is closed.
