And hence, the number of parts can be reduced without use of conventional retainers.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door handle device, and more particularly to a vehicle door handle device having a small number of parts and capable of preventing a pin for rotatably pivoting the handle from falling off.

[0002]

2. Description of the Related Art For example, a conventional inside handle is
As shown in FIGS. 7 to 10, a bracket 1 fixed to a vehicle panel and a handle 2 rotatably attached to the bracket 1 via a pin 3 are provided. The bracket 1 is made of a resin such as polycarbonate, ABS or polypropylene, and the handle 2 is made of a resin such as polyacetal. As shown in FIG. 10, the protruding portion 2 a of the handle 2 is arranged between the pair of support portions 1 a and 1 b formed on the bracket 1. Through holes 5 are coaxially formed in the support portions 1a and 1b of the bracket 1 and the protruding portions 2a of the handle 2, and the pins 3 are press-fitted into the through holes 5 as shown in FIG. The pin 3 is actually a spring pin that generates elasticity toward the inner wall of the through hole 5 when penetrated by the through hole 5. A rod 7 that is operatively connected to a door lock device (not shown) is arranged in the notch 6 formed in the bracket 1, and the rod 7 is attached to the protrusion 2a of the handle 2 that extends through the locking portion 1d of the bracket 1. Be worn. Therefore, when the handle 2 is manually pulled, the handle 2 rotates around the pin 3 and the door lock device can be operated via the rod 7.

[0003]

In the conventional door lock device, the pin 3 is press-fitted into the through hole 5, but the pin 3 is disengaged from the through hole 5 due to vibration generated when the vehicle is running or impact when the door is operated. There is danger. Therefore, conventionally, as shown in FIG. 9, a retainer 8 is used to prevent the pin 3 from falling off. The retainer 8 is formed by pressing a metal plate, and has a mounting portion 8a mounted on the fixed portion 1c of the bracket 1 and a stopper portion 8b protruding from the mounting portion 8a.
And The stopper portion 8b is arranged adjacent to the pin 3 and can prevent the pin 3 from falling off. However, the conventional door handle device that prevents the pin 3 from falling off requires the retainer 8, and thus has the drawback that the number of parts increases and the man-hour for attaching the retainer 8 also increases. Therefore, an object of the present invention is to provide an automobile door handle device that can reduce the number of parts and prevent the pin from falling off.

[0004]

An automobile door handle device according to the present invention comprises a bracket fixed to an automobile panel and a handle rotatably attached to the bracket via a pin. In this vehicle door handle device, an arm portion having a claw portion and elastically deformable is integrally formed with the bracket or the handle. After the arm portion is deformed and the pin is inserted into the through hole, the elasticity of the arm portion causes the claw portion to be arranged on the extension of the pin. According to the embodiment of the present invention, one end of the pin is arranged so as to face the claw portion of the arm portion, and the other end of the pin is arranged so as to face a bent portion formed on the handle. A pair of arms are formed on the bracket. In another embodiment of the present invention, a pair of arm portions each having a claw portion and a cover having an umbilicus portion and a pair of locking portions are formed integrally with the bracket.
The umbilicus of the cover is bent to lock the locking part to the claws of the pair of arms, and the cover is arranged on the extension of the pin inserted into the through hole. Since the arm portion having the claw portion, the cover or the arm portion is integrally formed with the bracket or the handle to prevent the pin from falling off, it is possible to reduce the number of parts without using a conventional retainer.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a vehicle door handle device according to the present invention will be described below with reference to FIGS.
1 to 6, the same parts as those shown in FIGS. 7 to 11 are designated by the same reference numerals, and the description thereof will be omitted. In the first embodiment of this vehicle door handle device, as shown in FIG. 1, the bracket 1 is provided around the through hole 5 into which the pin 3 is inserted.
A pair of arm portions 11 each having a claw portion 12 are integrally formed with the bracket 1, and the claw portions 12 of the arm portion 11 are arranged on the extension of the pin 3 inserted into the through hole 5. The arm portion 11 can be deformed by the elasticity of the resin. As shown in FIGS. 2 and 3, one end 3 a of the pin 3 is arranged to face the claw portion 12 of the arm 11 and the other end 3 b of the pin 3 is arranged.
Is arranged so as to face the bent portion 2b formed on the handle 2. As is apparent from FIG. 2, when the bracket 1 is manufactured, the protruding pin of the molding die forming the through hole 5 can be pulled out downward. At the time of assembly, the arm portion 11 is elastically deformed to insert the pin 3 into the through hole 5, and then the claw portion 12 is arranged on the extension of the pin 3 due to the elasticity of the arm portion 11. Since the arm portion 11 having the claw portion 12 is integrally formed with the bracket 1 to prevent the pin 3 from falling off, it is possible to reduce the number of parts without using a conventional retainer.

4 and 5 show a second embodiment in which the cover 14 is attached to the claw portion 12. In this example, a pair of arm portions 11 each having a claw portion 12 are integrally formed on the bracket 1 around the through hole 5 into which the pin 3 is inserted, and the cover is locked to the claw portions 12 of the pair of arm portions 11. 14 is formed on the bracket 1. The cover 14 has an umbilicus 14a connected to the bracket 1, a notch 14b formed in the umbilicus 14a, and a pair of locking portions 14c. The navel portion 14a is bent at the cutout portion 14b, and the locking portion 14c is attached to the claw portion 12. As a result, the cover 14 is arranged on the extension of the pin 3 inserted into the through hole 5 to prevent the pin 3 from falling off.

In the third embodiment shown in FIG. 6, a pair of arm portions 11 are attached to a tongue piece portion 2c formed integrally with the handle 2.
An example in which the claw portion 12 is formed is shown. In the example shown in FIG.
The arm portion 11 and the claw portion 12 formed on the handle 2 have substantially the same shape and operation effect as the arm portion 11 and the claw portion 12 shown in FIG.

[0008]

As described above, in the vehicle door handle device according to the present invention, the pin can be prevented from falling off with a small number of parts, so that the assembling man-hour can be simplified and the manufacturing cost can be reduced. it can.
