Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door checker for restricting opening / closing movement of a door.

[0002]

2. Description of the Related Art Generally, a door of an automobile is provided with a door checker for applying appropriate braking to the opening / closing motion and providing a moderation feeling at a predetermined opening angle. As a conventional door checker, for example, as shown in FIG. 5, one end is pivotally attached to the vehicle body, the other end is projected into the inside of the door, and at least two projections 41 are provided on the arm 42 and the arm 42. The guide member 43 is provided on the door side so as to exert a pressure contact force on the guide member 42, and has a resistance force when the protrusion 41 passes through the hole 44 of the guide member 43 so as to obtain a moderation feeling. Are known. According to this, the protrusion 4
1 has a chevron shape, the guide member 43 slides on the slope of the protrusion 41 when the hand is released from the door while the inner periphery of the hole 44 of the guide member 43 is in contact with the slope of the protrusion 41. Since an attempt is made to stop at the bottom of the valley 45 between the protrusions 41, the opening angle at which a feeling of moderation is obtained is limited, and the door cannot be held stationary at an arbitrary opening angle. for that reason,
For example, if the vehicle body is tilted due to the inclination of the road surface or a gust of wind blows, the check function will not work and the door will open unexpectedly, so the door will be released from the occupant's hand and the door on the road structure. Occasionally something like that would happen.

To deal with such inconvenience,
Japanese Unexamined Patent Publication No. 58-80079 discloses a door lock in which an electromagnetic device capable of locking a door at an arbitrary opening angle is provided, and a lock / unlock state is selected by a switch controlling operation of the electromagnetic device. A device has been proposed.

[0004]

However, according to the structure of the present invention, the door cannot be unlocked unless the electromagnetic device is demagnetized, so that the unlocking operation must be performed even when the door is closed. The door closing operation is generally performed simply by pulling the armrest, and it is unnatural that a special operation must be performed even when the door is closed, not when the door is opened. Although there are many familiar factors in such operability, it is not hard to imagine that the above-mentioned configuration would give a great discomfort to the door operation.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems of the prior art and to provide a vehicle door checker configured to be able to stand still at an arbitrary opening angle without impairing operability. It was devised in.

[0006]

In order to achieve such an object, according to the present invention, one end is connected to a vehicle body and the other end is projected into the door so that the door is opened from the inside of the door. In a vehicle door checker provided with a connecting means to be pulled out and a braking means for restricting the pulling-out operation of the connecting means from the inside of the door, when the door handle is opened, the braking action is released in both open and close directions. Therefore, in order to normally restrain the opening movement but not the closing movement, the braking means is provided with a selecting means that is interlocked with the door handle.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows a door around a vehicle to which a door checker constructed according to the present invention is applied. In the figure, a door 1 for opening and closing a side opening of a vehicle body is a pillar 2
It is pivotally attached to the rear end surface of the rear end via a hinge 3. A door checker 4 according to the present invention is provided between the rear end surface of the pillar 2 and the front end surface of the door 1. Further, the inner surface of the door 1 is provided with a door inner handle 5 for releasing a latch mechanism for holding a closed state and a silcon knob 6 for locking the door 1 by invalidating the door opening operation by the door handle. Has been.

As shown in FIGS. 2 and 3, the door checker 4 has one end pivotally attached to the pillar 2 and the other end protruding from the inside of the door 1 made of a metal plate. 1 and a braking means 8 provided inside the door 1 so as to restrict the relative movement between the door 1 and the door 1. At the other end of the arm 7, there is provided a stopper 10 that abuts against the outer surface of the housing 9 of the braking mechanism 8 and defines the opening limit of the door 1.

The braking mechanism 8 is provided in the housing 9 so as to sandwich both upper and lower surfaces of the arm 7, and a slider member 11 slidingly contacting the lower surface of the arm 7 and a pressing force for exerting a pressure contact force on the upper surface of the arm 7. Ball 12 (or roller)
It consists of A tapered surface 13 is formed inside the housing 9 so that a gap between the upper surface of the arm 7 and the upper surface of the arm 7 is narrowed toward the pillar 2 side. It is placed in the gap between the upper surface. The ball 12 has a tapered surface 1
The coil spring 14 elastically urges the coil spring 3 so as to bite between the arm 3 and the upper surface of the arm 7.

A releasing member 16 having a tapered surface 15 is provided between the member 1a forming the front end surface of the door 1 and the ball 12. The release member 16 is connected to the door inner handle 5 via a link rod 17 and a bell crank 18, and when the door inner handle 5 is pulled to perform a door opening operation, the tapered surface 1 is formed in the housing 9 of the braking mechanism 8.
5, the ball 12 is pushed back by the tapered surface 15 against the elastic force of the coil spring 14. Also, when the door inner handle 5 is released, the door inner handle 5 returns to its original position by the action of the return spring incorporated in the door inner handle 5, and accordingly the taper surface 15 is separated from the ball 12. To move to.

Next, an operating procedure of the above-mentioned device of the present invention will be described. When the door inner handle 5 is pulled, the link rod 17 moves in the direction shown by the arrow F1 in FIG. 2, and the release member 16 also moves in the same direction as the arrow F2. Then, the tapered surface 15 enters the housing 9 of the braking mechanism 8. As a result, the release member 16 separates the ball 12 from the tapered surface 13 of the braking mechanism 8 and releases the pressure contact force with respect to the arm 7. Therefore, in this state, resistance does not act on the door 1 in both directions of opening and closing.

When the door inner handle 5 is released and the door inner handle 5 returns to its original position, the link rod 17 moves in the direction opposite to the above, and the release member 1 accordingly.
6 moves in the direction in which it is pulled out from the housing 9 to release the regulation on the ball 12. Then, the ball 12 is pressed by the action of the coil spring 14 into the gap between the tapered surface 13 and the upper surface of the arm 7, and when the door 1 is opened, the ball 12 is dragged by the arm 7 and moves in the direction of cutting into the tapered surface 13. .
Due to the wedge effect at this time, a braking force is applied to the movement of the arm 7 in the direction to be pulled out from the door 1, and the door opening movement is restricted.

On the contrary, when the door 1 is closed, the arm 7 moves in the direction of entering the door 1, and the ball 12 moves in the direction of being pushed out from the tapered surface 13 accordingly. Therefore, the door 1 can be closed without resistance.

If the description is repeated according to the state of actual use, the door inner handle 5 is pulled when the door is opened.
The ball 12 is held at a position away from the tapered surface 13, and the door 1 can be opened and closed without resistance. Door 1
When the door is released from the door inner handle 5 when the desired opening has been reached, the ball 12 bites into the tapered surface 13 in the opening direction and resistance to the movement of the arm 7 is added, so that it cannot be opened further. . However, in the door closing direction, the ball 12 separates from the tapered surface 13, so that no resistance acts and the ball 12 can be closed freely.

A flexible belt is used in place of the arm 7 made of a metal plate, and an elliptical or egg-shaped rotating cam is used in place of the ball 12 and the tapered surface 13. The belt is always held between the slider and the slider member 11, and the door inner handle 5
The pulling cam may be configured to rotate in such a direction as to release the clamping force on the belt when is pulled.

Next, another embodiment of the device of the present invention will be described. As shown in FIG. 4, the door checker 21 of the present embodiment.
Is a wire 23 having one end connected to the end face of the pillar 2 and wound around a sheave 22 pivotally attached to the inside of the door 1 and the other end connected to the sheave 22, and is integrated with the sheave 22. And a disc 25 having a gear tooth profile 24 on its outer peripheral surface
And a braking member 26 pivotally attached to the inside of the door 1 so that it can be engaged with and disengaged from the gear tooth profile 24 of the disc 25. And, in the vicinity of the wire feeding hole 27 on the end face of the door,
The guide sheave 2 prevents the wire 23 from interfering with the feeding hole 27 and at the same time defines the bending radius of the wire 23.
8 are provided.

The braking member 26 has one end connected to the door inner handle 5 via a link rod 29.
When the door inner handle 5 is in the original position, the tooth profile 30 formed on the other end side meshes with the gear tooth profile 24 of the disc 25,
When the door inner handle 5 is pulled to open the door, the disk 2
The tooth profile 30 is separated from the gear tooth profile 24 of FIG.

The sheave 22 and the circular plate 25 are pivotally supported by the fixed shaft 31, and one end is engaged with the fixed shaft 31 and the other end is engaged with the sheave 22, and the wire 23 is wound by the torsion coil spring 32. Bounce is urged in the direction of taking.

The braking member 26 is preferably elastically urged in the engaging direction by the torsion coil spring 33 so that the door inner handle 5 is securely engaged with the gear tooth profile 24 when the door inner handle 5 is in the original position. .

Next, the operating procedure of this embodiment will be described. When the door inner handle 5 is pulled, the tooth profile 30 of the braking member 26 is separated from the gear tooth profile 24 of the disc 25 (position indicated by an imaginary line). Therefore, when the door 1 is opened while the door inner handle 5 is pulled, the door end surface is opened. The wire 23 is pulled as is separated from the pillar 2. Then, the sheave 22 and the disk 25 are rotated in the direction of arrow R against the elastic force of the torsion coil spring 32, and the wire 23 wound around the sheave 22 is paid out.

The door inner handle 5 at any door opening angle
When the hand is released from, the link rod 29 moves in the direction of arrow F3 to rotate the braking member 26 in the direction of arrow F4.
The tooth profile 30 meshes with the gear tooth profile 24 to stop the rotation of the sheave 22. As a result, the wire 23 is not extended from the sheave 22, and the door 1 cannot be opened any further.

Even if the door 1 is closed from this state, the sheave 2
Although 2 is still stopped, the wire 23 is loosened, so that no door closing resistance occurs. And the loose wire 23
When the door inner handle 5 is pulled in the next door opening operation, the tooth profile 24 of the disc 25 is changed to the tooth profile 3 of the braking member 26.
0 is separated and the sheave 22 is moved by the action of the torsion coil spring 32.
As it rotates, it is wound around the sheave 22 again.

Here, the relationship between the center of rotation of the braking member 26 and the position of the meshing portion of the gear tooth profile 24 is determined so that a tension force is generated in the rotational direction (R) of the disc 25. The braking member 26 is less likely to be repelled by the rotation of the disk 25, and the certainty of engagement between the gear tooth profile 24 and the tooth profile 30 is enhanced.

In the above embodiment, the relationship between the disc 25 and the braking member 26 is the meshing of the gear tooth profile 24 and the tooth profile 30, but even if the contact portion between the disc 25 and the braking member 26 is frictionally engaged, Depending on how the angle of the contact point between the rotation center of the braking member 26 and the disc 25 is set, a sufficient braking force can be obtained by biting due to the leading effect.

Although the above description has been made only for the case where the door inner handle 5 is used to perform the door opening operation, other door opening operation means can be connected to the link rod 17 (29).
It is also possible to configure so that the same effect can be obtained for the operation of the door outer handle.

[0027]

As described above, according to the present invention, the braking force is not applied to the door checker by the opening operation of the door handle, and the braking force is immediately applied to the door checker when the hand is released from the door handle. Therefore, the stationary opening angle of the door can be set steplessly, and even if the occupant releases the door due to a gust of wind, for example, the door will stop immediately, so that the door will hit the road structure. You can open the door to the occurrence of such troubles. Moreover, when the door is closed, no resistance is applied regardless of the operating condition of the door handle, so the door can be closed freely.
