DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail based on specific examples shown in the accompanying drawings.
[0008]
FIG. 1 is a front view of a door handle device to be assembled on a vehicle compartment side of a door of an automobile to which the present invention is applied, and FIG. 2 is an arrow II-II in FIG. 1 to show an assembling procedure of the door handle device. It is the sectional side view seen about the line. As shown in the drawing, the door handle device includes a rectangular dish-shaped case 1, and a door handle 2 and a lock handle 3 that are attached so as to be received in a recess of the case 1. As shown in FIG. 2, a screw support hole 5 through which the tapping screw 4 is inserted is provided in the bottom wall of the recess of the handle case 1.
[0009]
The door handle device is attached to the door panel 6 as shown in FIG. 2, with the door handle 2 and the lock handle 3 being integrally attached to the handle case 1 as described above. In this specific example, the tapping screw 4 is not directly screwed into the door panel 6 and fixed, but the grommet 7 is pushed into the mounting hole 6 a provided in the door panel 6 and the tapping screw 4 is attached to the grommet 7. The handle case 1 is fixed to the door panel 6 by screwing.
[0010]
The grommet 7 is formed in a substantially rectangular parallelepiped shape, and a tapping hole 7 a for screwing the tapping screw 4 is formed as a long hole having a narrower width than the outer diameter of the tapping screw 4. Then, the grommet 7 is attached to the door panel 6 so that the longitudinal direction of the tapping hole 7a of the grommet 7 is aligned with the operation direction (left and right direction in the figure) of the connecting rod for door lock operation connected to the door handle 2. By doing so, the handle case 1 can be displaced and fixed in the longitudinal direction of the tapping hole 7a of the grommet 7, so that the door handle 2 and the connecting rod can be easily positioned.
[0011]
The door handle 2 is rotated in a standing direction with respect to the handle case 1 when the door lock is released, and the body 2a serving as the center of rotation and the direction perpendicular to the rotation axis from the body 2a. An extending lever-shaped gripping portion 2b and a pair of long and short shaft portions 2c projecting coaxially from the body portion 2a in the left-right direction are formed by integral molding. The lock handle 3 described above is rotatably supported on the long axis side of the shaft portion 2c, and each axial direction of the shaft portion 2c can be rotated by a shaft support hole 8 provided in the side wall portion of the handle case 1. The end is pivoted.
[0012]
In addition, in the shaft part 2c, the part pivotally supported by the shaft support hole 8 is formed in a D-shaped cross-sectional shape. Further, a part of the handle case 1 forming the shaft support hole 8 is cut out so as to communicate with the outside, and a gate portion 9 is provided. The width of the gate portion 9 is D-shaped on the shaft portion 2c. It is made the extent which can pass only the thin part of a cross-sectional part. As a result, the door handle 2 can be easily assembled to the handle case 1, and the shaft handle hole 8 can be rotated by rotating the door handle 2 within a range where the narrow portion of the D-shaped cross section does not coincide with the gate portion 9. The withdrawal from the is prevented.
[0013]
Further, the handle case 1 is provided with an opening 1a into which the door handle 2 can be inserted when the door handle 2 is assembled to the handle case 1 as shown in FIG. Therefore, in the door handle device, when the above-described assembled state is set before attaching to the door panel 6, the door handle 2 is first opened from the back side of the handle case 1 to the opening 1a as shown in FIG. Is inserted as shown by arrow A in FIG.
[0014]
Next, the narrow portion of the D-shaped cross section of the shaft portion 2c is aligned with the gate portion 9, and the shaft portion 2c is completely stored in the shaft support hole 8 as shown in FIG. The shaft 2c is tilted toward the recess of the handle case 1 as shown by the arrow B in FIG. Then, since the alignment position of the narrow portion of the D-shaped cross section and the gate portion 9 is shifted, the shaft portion 2c does not come out from the shaft support hole 8, so that the door handle 2 is assembled integrally with the handle case 1. Can be easily realized. In the state of use attached to the door, the door handle 2 is directed into the recess of the handle case 1 by a torsion coil spring (not shown) so that when the hand is released from the door handle 2, it naturally returns to the storage position. Since the bullet is energized, the door handle 2 does not fall off in the assembled state.
[0015]
The door handle device assembled in this way is attached to the door panel 6 as described above, and the door panel 6 has a stopper surface 6b formed by bending a part thereof as a stopper portion as shown in FIG. Is provided. Further, the door handle 2 is provided with a projecting piece portion 2d that protrudes from the body portion 2b toward the side opposite to the gripping portion 2a, so that the door handle 2 stands up with respect to the handle case 1. When the door handle 2 is rotated, the protrusion 2d is abutted against the stopper surface 6b to define the maximum rotation angle when the door handle 2 is opened.
[0016]
As shown in FIG. 5, the specified position is before the narrow portion of the D-shaped cross section of the shaft portion 2 c is aligned with the gate portion 9 when the door handle 2 is rotated when the door is opened. Therefore, in the assembled door handle 2, the shaft portion 2c does not come out of the shaft support hole 8 even when the door handle 2 is raised to the maximum rotation angle.
[0017]
Further, in the structure shown in the conventional example, the snap for connecting the rod is abutted against the handle case. Therefore, in consideration of rigidity and durability, the snap tends to be enlarged. According to this, since the stopper portion is formed by a highly rigid door panel, such a large component is not required.
[0018]
Further, according to the structure of the present invention, as shown in FIG. 4, when the door handle 2 is assembled to the handle case 1, a part of the body portion 2 a of the door handle 2 hits the opening 1 a. A thin portion of the D-shaped cross section of the shaft portion 2 c is made to coincide with the gate portion 9. Therefore, the shaft portion 2c and the gate portion 9 can be easily positioned not only at the time of assembly but also at the time of removal, and the assembly and maintenance properties are good.
[0019]
In the above embodiment, the shaft portion is provided on the door handle 2 side and the shaft support portion is provided on the handle case 1 side. However, the present invention is not limited to this, and the shaft portion is provided on the handle case 1 side. You may provide a shaft support part in this.
[0020]
【The invention's effect】
Thus, according to the present invention, the shaft portion is formed in a D-shaped cross-sectional shape so that the shaft portion serving as the rotation center of the door handle can be easily assembled to the shaft support portion, and the shaft portion is formed from the gate portion of the shaft support hole. In order to prevent the part from falling off, the means for defining the maximum rotation angle of the door handle is configured without using a separate part, and the door handle is attached to the door panel, which is naturally performed when the door handle device is assembled. Since the maximum rotation angle is defined, the process can be simplified and the assembly cost can be reduced. Moreover, since the stopper part which prescribes | regulates the maximum rotation angle of the said door handle was formed with the door panel which is the other party which attaches a door handle apparatus, there is no problem in rigidity and durability.
