DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling structure of a vehicle door handle device capable of adjusting a handle design surface.

[0002]

2. Description of the Related Art In a door handle device provided inside a door of an automobile, a door handle for releasing (unlatching) a latch device on the door side when the door is opened, and a lock handle for preventing unlatch by unlatch operation of the door handle. Are provided in a common handle case.

Conventionally, there is a door handle device as described above, which is configured as shown in FIG. In general, a door handle device is provided at a position on the vehicle front side of the door where the occupant can easily operate the door handle device. A handle case 1 of the door handle device has a door handle 2 and a lock handle 3 in front and rear directions of the drawing, respectively. They are pivoted independently and pivotally coaxially with one another. A door latch device 5 is fixed to the rear end of the door panel 4, and a first and second levers 6, 7 rotatably supported on a base 5a of the latch device 5, respectively.
The door handle 2 and the first lever 6 are connected via the first rod 8 and the lock handle 3 and the second
The levers 7 are connected via second rods 9 respectively.

In the above-described door handle device, since there is a dimensional error between the members, when the door handle device is mounted on the door panel, both design surfaces 2a, 3a (3a) of the door handle 2 and the lock handle 3 are provided. It is necessary to make it adjustable so that the surface exposed on the indoor side) can be designed.

For example, in general, the door handle 2 is spring-biased toward the stowed position so that the door handle 2 is naturally returned into the handle case 1 by rotating the door handle 2 in a direction in which the door handle 2 is pulled out and then releasing the hand. On the other hand, the lock handle 3 is rotatable between two positions of lock and unlock. Therefore, since the door handle 2 is spring-biased toward the storage position as described above, the handle case is set within the range of the adjustment allowance (a + b in the drawing) provided on the first lever 6 interlocking with the door handle 2. If 1 is displaced (the distance from the latch device 5 is changed), the position of the design surface 2a of the door handle 2 does not change. On the other hand, when the position of the handle case 1 changes, the lock handle 3 rotates with the second lever 7 having no adjustment allowance as a fixed point.

[0006] For example, the handle case 1 is temporarily fixed.
When the distance between the door handle 2 and the latch device 5 is short, as shown in FIG.
Is slightly raised, so that the lock handle 2 protrudes from the door handle 2 indicated by the imaginary line, and the design surfaces 2a and 3a become uneven. In this case, by displacing the handle case 1 in a direction away from the latch device 5 as shown by the arrow A in the figure, the lock handle 3 can fall into the handle case 1 as shown by the arrow B. become,
The two design surfaces 2a and 3a match.

In order to allow the handle case 1 to be displaced as described above, the handle case 1 can be displaced from the door panel 4 by a slot or the like.
In the illustrated example, a grommet 11 having a long hole is attached to the door panel 4 as a counterpart of the tapping screw 10 for attaching the handle case 1, and the tapping screw 10 is screwed into the long hole of the grommet 10.

[0008]

However, in the structure described above, in order to completely unlatch the latch device 5 when the door handle 2 is operated, the stroke of the first lever 6 due to the operation of the door handle 2 is required. The (amount of movement of the rod in the axial direction) needs to be equal to or greater than the value obtained by adding the unlatching stroke c to the adjustment allowance (a + b). Further, considering the elongation of the first rod 8, it is necessary to further add the elongation α. Therefore, the door handle 2 is brought into contact with a stopper provided on the case so that the maximum stroke H of the door handle 2 becomes (a + b + c + α). Further, in the first lever 6, there is a lever abutting position beyond the unlatching stroke c, and the maximum stroke L is from the neutral position of the adjustment allowance to the lever abutting position.

Then, the handle case 1 is displaced,
When the design surface 3a of the lock handle 3 is adjusted with respect to the door handle 2 and the position of the first lever 6 reaches the position of the limit of the adjustment allowance a, the door is moved beyond the maximum stroke L of the first lever 6. The maximum stroke H of the handle 2 may be larger.

When the maximum stroke H of the door handle 2 is larger than the maximum stroke L of the first lever 6 as described above, when the door handle 2 is operated to release the latched state, the first lever Even after 6 reaches the end position, the operation allowance for the door handle 2 remains,
The door handle 2 can be rotated more than that. In that case, the first rod 8 is forcibly pulled, and there is a problem that the first rod 8 may be deformed.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, in a door handle device in which the design of a door handle and a lock handle is adjusted, an unreasonable deformation of a connecting rod with a latch device is required. According to the present invention, a first lever rotatable between a position where the latch mechanism of the door can be unlatched and a retracted position is realized, In order to remotely operate a latch device provided at an end portion of a door panel integrally having a second lever rotatable between both a lock position and an unlock position for preventing the unlatch,
A door handle device provided at a position separated from the latch device on the door panel, wherein the door handle device is attached to the door panel so that a distance between the door handle device and the latch device can be changed; A door handle connected via a first rod so as to be able to rotate in conjunction with the first lever and pivotally supported by the handle case; and a second door handle so as to be able to rotate in conjunction with the second lever. A lock handle connected via a rod and pivotally supported by the handle case. By displacing the handle case, the design surfaces of the two handles that rotate with respect to the respective levers are formed. In order to align the door handle, an adjustment margin is provided in the rotation range of the first lever, and the door handle is elastically urged toward the non-operating position, so that the door hand Of the stopper portion which partially is impinged in the door handle so as to define a maximum pivot angle during the door opening operation, and shall be formed by processing a portion of the door panel.

Accordingly, the position of the stopper portion which defines the maximum rotation angle of the door handle changes relatively with respect to the displacement of the handle case, and the position of the handle case changes by adjusting the design surface. The maximum rotation angle of the door handle can be changed according to the adjustment allowance of
The amount of rotation of the door handle can be increased or decreased according to the magnitude of the amount of rotation of the lever, and it is possible to prevent the door handle from being excessively rotated.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to specific examples shown in the accompanying drawings.

FIG. 1 is a side view of a main part of a door handle device provided on a vehicle cabin side of a door of an automobile to which the present invention is applied. The same reference numerals as those in FIG. And a detailed description thereof will be omitted. FIG. 1 also shows the first lever 6 of the latch device 5 connected to the door handle 2 via the first rod 8 as in the conventional example.

In the door handle 2 according to the present invention, when the latch device is unlatched, the handle case 1
It is rotated in the direction of erecting from inside, and at this time, a lever-shaped grip portion 2b for hanging a finger extends perpendicularly to the axis of a shaft portion 2c protruding to both sides of the door handle 2 as a rotation axis. It is formed to exist. Both ends in the axial direction of the shaft portion 2c are pivotally supported by a shaft support hole 12 provided in a side wall portion of the handle case 1.

In the shaft portion 2c, a portion pivotally supported by the shaft support hole 12 is formed in a D-shaped cross section. In addition, a part of the handle case 1 forming the shaft support hole 12 is cut off so as to communicate with the outside, and the width of the cutout portion passes only through the narrow portion of the D-shaped cross section of the shaft portion 2c. To the extent possible. As a result, the door handle 2 can be easily assembled to the handle case 1, and the door handle 2 is rotated within a range where the thin portion of the D-shaped cross section does not coincide with the cut-out portion, so that the door handle 2 can be removed from the shaft support hole 12. Is prevented from coming off.

Then, the door handle device assembled by incorporating the door handle 2 and the lock handle 3 into the handle case 1 is screwed into the long hole of the grommet 11 fixed to the door panel 4 as described above. 4 is provided with a stopper surface 4a formed as a stopper portion by bending a part thereof as shown in FIG. Further, the door handle 2 is provided with a protruding portion 2d protruding from a shaft portion 2c to a side opposite to the grip portion 2b, and as shown by an imaginary line in the figure, the door handle 2 is provided. When it is turned in the direction in which it rises with respect to the handle case 1, the projecting piece 2d abuts against the stopper surface 4a. Thereby, the maximum rotation angle at the time of the door opening operation of the door handle 2 is defined.

FIG. 1 shows a case where the tapping screw 10 is located at the center of the long hole of the grommet 11 in a neutral state.
In the present invention, in this state, the handle stroke H (stroke between the two states of the solid line and the imaginary line in the figure) is adjusted to the adjustment allowance a.
The position where the stopper surface 4a is formed is set so as to be equal to the sum of the stopper surface 4a and the unlatching stroke c. Even in the door handle device assembled in this manner, both the design surfaces 2a and 2 of the door handle 2 and the lock handle 3 are provided.
To adjust b, the handle case 1 is displaced in the same manner as in the conventional example.

For example, when adjusting the design surfaces 2a and 2b by displacing the handle case 1 in a direction approaching the latch device 5, the displacement is performed within the range of the adjustment allowance b of the first lever 6. . In this case, as shown in FIG. 2, the handle case 1 moves away from the stopper surface 4a, and the handle stroke H1 of the door handle 2 in the limit in that case is determined by the difference between the unlatch stroke c and both adjustment allowances (a + b). Become sum. Therefore, the maximum rotation angle in the upright direction of the door handle 2 is larger than that in the neutral state in FIG. 1, but is not so large as to affect the door handle operation.

When the handle case 1 is displaced away from the latch device 5, the handle case 1 is displaced within the range of the adjustment allowance a of the first lever 6. In this case, as shown in FIG. 3, the handle case 1 approaches the stopper surface 4a, and the handle stroke H2 of the door handle 2 in that case is only the unlatch stroke c. Therefore, the maximum rotation angle in the upright direction of the door handle 2 is smaller than that in the neutral state in FIG. 1, but also in this case, it is not so large as to affect the door handle operation in the same manner as described above.

As a result, the position of the door handle 2 is displaced relative to the stopper surface 4a by an amount corresponding to the adjustment allowance, so that the amount of rotation of the door handle 2 is always added to the unlatching stroke c by the adjustment allowance. Can only be. When the first lever 6 is displaced by an unlatching stroke c required for the unlatching operation, the door handle can be prevented from hitting against the stopper surface 4a and the door handle 2 can be prevented from further rotating. Is not forcibly pulled.

By setting the length of the long hole of the grommet 11 in accordance with the maximum displacement (a + b) of the handle case 1, an arbitrary positioning setting between the two states shown in FIGS. 2 and 3 can be achieved. It is possible. Further, the maximum stroke L of the first lever 6 in the unlatching direction is an amount obtained by adding the extension α to the unlatching stroke c as in the conventional example.

[0023]

As described above, according to the present invention, the position of the stopper portion that defines the maximum rotation angle of the door handle changes relative to the displacement of the handle case, and the design surface is adjusted. Since the maximum rotation angle of the door handle can change according to the adjustment allowance when the position of the handle case changes, the rotation amount of the door handle can be increased or decreased according to the magnitude of the rotation amount of the first lever, It is possible to prevent the door handle from being unnecessarily rotated, and prevent the rod connecting the two members from being unnecessarily deformed.
