Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicle door handle device, and particularly relates to a vehicle door handle device that is designed to simplify the structure and prevent the inside handle from coming off in the rotational direction. .

[Prior Art] An inside handle for unlocking the door is attached to the door panel of a vehicle.
Conventionally, as shown in FIG. 3, an inside handle 2 was rotatably attached to an escutcheon 1 fixed to a door panel with a pin 3. For this reason, escutcheon 1 and inside handle 2
Since it is necessary to form pin insertion holes 4 and 5 in both of the parts, and the iron pin 3 is required, the number of parts is large, the number of assembly steps is required, and the pin 3 inevitably comes out.

In order to improve this, as shown in FIG.
It has been proposed to form shaft holes 8 and 9 into which the shafts are fitted (Japanese Utility Model Application Publication No. 56-34957).

[Problems to be solved by the invention] However, in such a conventional device, the inside handle 2 is pushed into the escutcheon 1 from the front side to fit the protruding shafts 6, 7 into the shaft holes 8, 9. Therefore, when the inside handle 2 is rotated in the unlocking direction using the protruding shafts 6, 7 as fulcrums, the engagement between the protruding shafts 6, 7 and the shaft holes 8, 9 changes and the load is reduced. There was a problem in which the inside handle 2 acted in the opposite direction to the direction in which the inside handle 2 was pushed into the escutcheon 1, causing the inside handle 2 to come off.

[Purpose of the invention] The present invention was devised to effectively solve the problems of the prior art described above.The purpose of this invention is to reduce the number of parts, allow quick assembly, and to provide a vehicle with an inside handle that is difficult to remove. We are in providing door handle equipment.

[Summary of the invention] In order to achieve the above object, the present invention forms an opening for storing the inside handle in the escutcheon attached to the door panel, and a wall opposite to the opening is provided with an opening on both sides of the inside handle. The present invention is characterized in that a shaft hole is formed into which the protruding pivot shaft is fitted, and an elastic locking pawl that guides and locks the protruding shaft is formed on the rear side of the opening of the shaft hole.

[Example] An example of the present invention will be described below in detail based on the accompanying drawings.

In FIGS. 1 and 2, reference numeral 10 denotes an escutcheon which also serves as a mounting base and is fixed to a door panel 11 of a vehicle by screws or the like, and is integrally molded from synthetic resin. The escutcheon 10 is formed with an opening 13 for rotatably housing an inside handle 12 for unlocking a door lock attached to a vehicle door.

The inside handle 12 is integrally molded from synthetic resin, and has a connecting portion 14 for connecting a link M leading to the door lock at its base end, and protruding shafts 15 and 16 at both sides of the base end. ing.

On the other hand, the protruding shaft 1 of the inside handle 12 is located on the opposite inner wall of the opening 13 of the escutcheon 10.
5, 16 are rotatably fitted into shaft holes 17, 18
is formed. Both shaft holes 17 and 18 are openings 1
partitioned by inverted U-shaped protrusions 19 and 20 that are open facing the rear side (downward in the figure) of 3;
The openings of these protrusions 19 and 20 have protruding shafts 1 that cover them and are pushed in from the rear side of the openings 13.
5 and 16 while guiding it over the shaft hole 17,
Elastic locking pawls 21 and 22 for locking into the inside of the housing 18 are formed in a protruding manner, respectively. Incidentally, in order to smoothly fit the protruding shafts 15 and 16 into the shaft holes 17 and 18, inclined guide surfaces 23 and 24 are formed on the upper surfaces of the elastic locking claws 21 and 22, and the protruding shafts 15 and 1
Curved portions 25 and 26 are formed at the ends of 6.

Next, the case of assembling the vehicle door handle device having the above configuration will be described.

First, push the inside handle 12 from behind the opening 13 into the escutcheon 10 before it is attached to the door panel,
6 is the inclined guide surface 23 on the elastic locking claws 21, 22,
24. The protruding shafts 15 and 16 fit into the shaft holes 17 and 18 by riding over the elastic locking claws 21 and 22 while elastically deforming them.
Since the protruding shafts 15 and 16 fitted into the shaft holes 17 and 18 are completely blocked from moving toward the front side (upward in the figure) of the opening 13 by the U-shaped protrusions 19 and 20,
Even when the inside handle 12 is rotated in the unlocking direction as shown in FIG. 2, the load F generated at this time can be reliably received by the U-shaped protrusions 19 and 20, allowing the protrusions 19 and 20 to come off. can be reliably prevented.

And the connecting part 14 of the inside handle 12
A door lock link M is connected to the escutcheon 10, and the escutcheon 10 is fixed on the door panel 11.

[Effects of the invention] In summary, the present invention provides the following excellent effects.

(1) A protruding shaft is formed on the inside handle, which fits into the shaft hole formed in the escutcheon, so a pin is not required and the number of parts is reduced.

(2) An elastic locking pawl is formed on the rear side of the opening of the shaft hole, and the protruding shaft is slid and guided along the elastic locking pawl, and is fitted into the shaft hole by passing over the elastic locking pawl. Since the inside handle is locked by the elastic locking pawl, the inside handle can be easily and quickly assembled to the escutcheon.

(3) Since the protruding shaft is fitted into the shaft hole from the rear side of the opening, it is possible to completely prevent the protruding shaft from moving toward the front of the opening, and the inside handle can be rotated in the unlocking direction. There is no risk that the protruding shaft will come off the shaft hole even if it is moved.
