You. That is, opposing operation load characteristics are required when the door is opened and when the door is closed.

On the other hand, in the above-described two conventional vehicle door check devices 100 and 130, only one type of check pattern 122 for determining the door opening / closing operation load and, consequently, the door opening / closing operation feeling is set. Therefore, the check pattern 122 is set by selecting one of the operation load characteristics when the door is opened and the operation load characteristics when the door is closed. This means that the realization of the operation load characteristic not selected is abandoned.

The present invention has been made in consideration of the above-described circumstances, and has as its object to provide a vehicle door check device that can provide a good operation load characteristic and an operation feeling both when the door is opened and when the door is closed.

[0014]

According to a first aspect of the present invention, a check pattern comprising a plurality of concave and convex surfaces is formed at an intermediate portion in the longitudinal direction at one end in the longitudinal direction so as to be relatively rotatable with the vehicle body. Door check case provided with a long check arm and a moving body that is provided on the door hinge side of the vehicle door and traces the check arm check pattern as the door opens and closes, thereby increasing or decreasing the door opening / closing operation load. An assembly part comprising: a first door opening check pattern and a door opening door exhibiting mutually different operation load characteristics at a middle part in a longitudinal direction of the check arm. A second check pattern for closing is set.

According to a second aspect of the present invention, there is provided a vehicle door check device according to the first aspect, wherein the first check pattern and the second check pattern are arranged side by side, and both of them are doors. It is characterized in that it is connected to each other at three switching surfaces corresponding to each of when the door is fully opened, when the door is half-opened, and when the door is fully closed.

According to a third aspect of the present invention, there is provided a vehicle door check device according to the second aspect, wherein the movable body is switched from the first check pattern to the second check pattern and the movable body is switched. The switching from the second check pattern to the first check pattern is performed by using movements in opposite directions acting on the door check case Assy portion and the check arm when the door is opened and closed.

According to a fourth aspect of the present invention, in the vehicle door check device according to any one of the first to third aspects, the movable body includes a ball rolling on a check pattern. It is characterized by comprising.

According to the first aspect of the present invention, when the door opening / closing operation of the vehicle door is performed, the moving body provided in the door check case Assy portion is formed at the longitudinal middle portion of the check arm. Trace over the check pattern. The check pattern includes a plurality of uneven surfaces, and the moving object traces the plurality of uneven surfaces to increase or decrease the door opening / closing operation load.

Here, in the present invention, two types of check patterns are set. In other words, according to the present invention, two types of the check arm include a first check pattern in which the moving object traces when the door is opened and a second check pattern in which the moving object traces when the door is closed. Check pattern is set. In addition, the first check pattern and the second check pattern exhibit different operation load characteristics. Therefore, the operation load characteristics required when the door is opened can be realized by the first check pattern, and the operation load characteristics required when the door is closed can be realized by the second check pattern.

According to the second aspect of the present invention, the first check pattern and the second check pattern described above are arranged side by side, and they are respectively provided when the door is fully opened, when the door is half-opened, and when the door is fully closed. Since the three switching surfaces are connected to each other, for example, when the vehicle door is fully opened and then fully closed, the moving body moves from the corresponding switching surface when the door is fully closed to the first check pattern side. Move to the first
After tracing over the check pattern, move to the second check pattern side at the switching surface corresponding to when the door is fully opened,
It traces over the second check pattern and returns to the original position.

As described above, in the present invention, the first door opening door is opened.
Since the check pattern and the second check pattern for closing the door are arranged side by side, and they are connected to each other at three switching surfaces corresponding to each of when the door is fully opened, when the door is partially opened, and when the door is fully closed, The size of the check arm, especially in the width direction, can be avoided.

According to the third aspect of the present invention, the switching of the moving object from the first check pattern to the second check pattern and the second check pattern to the first check pattern are performed at the three switching surfaces. The switching to is performed by using movements in opposite directions acting on the door check case Assy portion and the check arm when the door is opened and closed. Specifically, when the door is open, the door check case Assy portion provided on the door hinge side of the vehicle door moves to the outside of the vehicle compartment, whereas the check arm attempts to stay at that position. When viewed from the side of the check case assembly section, the check arm is relatively swung toward the vehicle interior. Conversely, when the door is closed, the door check case Assy moves toward the vehicle interior, whereas the check arm tries to stay at that position. Is relatively swung to the outside of the cabin. This itself is similarly applied to a conventional vehicle door check device. However, in the present invention, the relative movement is used to switch between the first check pattern and the second check pattern of the moving object. It is intended to be performed. Therefore, the switching between the first check pattern and the second check pattern of the moving object can be performed without adding any special configuration.

According to the fourth aspect of the present invention, since the above-mentioned moving body includes the ball rolling on the check pattern, a smooth movement of the moving body can be secured. In particular, in relation to the second and third aspects of the present invention, it is necessary for the moving body to move in the direction crossing the juxtaposed first check pattern and the second check pattern. Since the rolling can also be performed in the direction, the mutual transfer operation can be performed extremely smoothly.

Side).

In the above configuration, the shoe 26, the check ball 28, and the compression coil spring 30 correspond to the "moving body" in the present invention.

Next, the operation and effect of this embodiment will be described.

First, the opening and closing operation of the side door 32 and the accompanying movement of the door check case assembly 14 and the check arm 12 will be described.

As shown in FIG. 3, when the side door 32 is opened, the door check case Assy portion 14 fixed to the side door 32 moves outside the vehicle cabin around the arm rotation center line P (arrow A in FIG. 3). Direction side). At this time, since the check arm 12 attempts to keep the same state, when viewed from the door check case Assy portion 14, the check arm 12 relatively swings toward the vehicle interior (the direction of the arrow C in the figure). Will be done.

Conversely, when the side door 32 is closed, the door check case Assy portion 14 fixed to the side door 32 turns around the arm rotation center line P toward the vehicle interior (in the direction of arrow B in FIG. 3). Is done. At this time, in order to keep the check arm 12 as it is, when the check arm 12 is viewed from the door check case Assy portion 14, the check arm 12 relatively swings toward the outside of the vehicle compartment (in the direction of the arrow D in the figure). Will be done.

To summarize the correlation between the door opening / closing operation and the movement of each part described above, when the side door 32 is opened, the door check case Assy part 14 turns to the outside of the passenger compartment, and the check arm 12 swings to the inside of the passenger compartment. Can be On the other hand, when the side door 32 is closed, the door check case Assy 1
4 turns to the inside of the cabin, and the check arm 12 is swung to the outside of the cabin. That is, door check case Assy part 1
4 and the check arm 12 tend to move in mutually opposite directions.

Next, based on the relative movement, the check ball 28 is moved to the check pattern 4 according to the door opening / closing operation.
2 will be described.

FIG. 7 shows where the check ball 28 is on the check pattern 42 in accordance with the door opening / closing operation. As shown in this figure, when the side door 32 is in the fully closed state, the check ball 28 of the door check case Assy portion 14 is located on the first switching surface 56. From this state, the side door 32
Is released, the check arm 12 is swung toward the vehicle interior according to the above-described relative movement. For this reason, the check ball 28 is the first ball set outside the cabin.
First gentle slope 4 of first raised portion 48 of check pattern 44
8A, and moves up and down while rolling on the first raised portion 48 in the direction of arrow E in the same figure to reach the second switching surface 58 corresponding to the door half-open state. Thereafter, when the side door 32 is further opened from the half-open state of the door, the check ball 28 is moved to the second raised portion 50 of the first check pattern 44.
Ascends and descends while rolling up, and reaches the third switching surface 60 corresponding to the fully opened state of the door.

Looking at the above-mentioned door operation load characteristics when the door is opened, the characteristics are as shown in a graph X in FIG. That is, when the side door 32 starts to be opened, the check ball 28 rolls on the long first gentle slope 48A of the first raised portion 48, so that the operation load is relatively low. The low operation load means that the side door 32 can be opened smoothly. Therefore, according to the present embodiment, when the door is opened, the side door 32 can be smoothly opened, and a good operation feeling can be obtained.

After the one-cushion is placed in the half-open state of the door, the check ball 28 rolls on the second raised portion 50, so that the operation load is slightly increased, and the occupant needs to open the side door 32 fully. To inform.

On the other hand, when the side door 32 in the fully opened state is closed, the check arm 12 is swung to the outside of the vehicle according to the above-described relative movement. For this reason, the check ball 28 held on the third switching surface 60 rides on the third gentle slope 52A of the third ridge 52 of the second check pattern 46 set on the vehicle interior side, and the third ridge is formed. The roller 52 moves up and down on the portion 52 while rolling in the direction of arrow F in FIG. Thereafter, when the side door 32 is further closed from the door half-open state, the check ball 28 moves up and down while rolling on the fourth raised portion 54 of the second check pattern 46, and the first cut corresponding to the door fully closed state. Replacement surface 5
Reach 6.

Looking at the above-mentioned door operation load characteristics when the door is closed, the characteristics are as shown in a graph Y in FIG. That is, when the side door 32 starts to be closed, the check ball 28 rolls on the long third gentle slope 52A of the third raised portion 52, so that the operation load is relatively low, and the operation to start closing smoothly is performed. It can be carried out. When the closing of the side door 32 is approaching, the check ball 28 rolls at an accelerated speed on the short fourth steep slope 54 </ b> C of the fourth raised portion 54, so that the side door 32 can be closed vigorously. In other words, as the check ball 28 descends on the steep fourth steep slope 54C, it is possible to obtain assisting force when the occupant fully closes the side door 32. Therefore, according to the present embodiment, when the door is closed, the side door 32 can be firmly closed, and a good operation feeling can be obtained. In particular, a problem that the side door 32 is difficult to close has been pointed out in a vehicle in which the side door 32 is large in spite of a small cabin space. However, according to the present embodiment, the side door 32 of such a vehicle has been pointed out. There is also an advantage that the difficulty of closing can be reduced.

In the case where the side door 32 is temporarily opened from the fully closed state to the half open state again to be fully closed again, the check ball 28 rides over the first raised portion 48 of the first check pattern 44 and the second After arriving at the switching surface 58, it crosses over the fourth raised portion 54 of the second check pattern 46 and returns to the first switching surface 56.

As described above, in the present embodiment, the two types of check patterns (that is, the door open state) are tuned so that the check arm 12 that determines the operation load characteristic at the time of opening and closing the door exhibits the optimum operation load characteristic. The first for time
Since the check pattern 44 and the second check pattern 46) for when the door is closed are set, a good operation load characteristic and an operation feeling can be obtained both when the door is opened and when the door is closed.

In this embodiment, the check arm 1
After the first check pattern 44 and the second check pattern 46 are arranged side by side in the middle part in the longitudinal direction of No. 2, the first check pattern 44 and the second check pattern 46 correspond to the first time when the door is fully closed, the time when the door is half open, and the time when the door is fully open.
Since the switching surface 56, the second switching surface 58, and the third switching surface 60 are connected to each other, the check arm 12
In particular, it is possible to avoid enlargement in the width direction. As a result, according to the present embodiment, the compact check arm 12 can obtain good operation load characteristics when opening and closing the door, and furthermore, an operation feeling.

Further, in this embodiment, when the door is opened and closed, the door check case assembly 14 and the check arm 1 are checked.
The change of the check ball 28 from the first check pattern 44 to the second check pattern 46 performed on the first switching surface 56 to the third switching surface 60 using the movement in the opposite direction acting on the second switching pattern 56. (Transfer) and switching (transfer) from the second check pattern 46 to the first check pattern 44 are performed, so that the first check pattern 44 of the check ball 28 can be provided without adding any special configuration. In addition, switching (switching) between the second check patterns 46 can be performed. As a result, according to the present embodiment, the structure of the vehicle door check device 10 does not become complicated.

In this embodiment, the pair of shoes 26
, The check ball 28 is held, and the check ball 28 rolls on the check pattern 42, so that a smooth movement of the shoe 26 can be secured. In particular, in the present embodiment, it is necessary that the shoe 26 also move in the direction crossing the first check pattern 44 and the second check pattern 46 on the first switching surface 56 to the third switching surface 60. Since the check ball 28 can roll in any direction, it is possible to perform the inter-switching operation extremely smoothly.

In this embodiment, the check arm 1
2, the first check pattern 44 and the second check pattern 46 are formed on the upper and lower surfaces, respectively.
It is also possible to adopt a configuration in which the first check pattern and the second check pattern are respectively formed on both side surfaces of the check arm. In this case, the door check case Assy
The pair of shoes and balls of the section are arranged in the door thickness direction with the check arm interposed therebetween, but can be installed if the door thickness of the side door is appropriate.

Further, in the present embodiment, the configuration in which the check ball 28 is rotatably held by the shoe 26 is adopted, but the present invention is not limited to this, and another configuration may be adopted. For example,
A configuration in which the pattern contact portion of the shoe is formed in a spherical shape (the shoe in this case is broadly understood as a “sliding body”) may be employed.
