Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door handle, and more particularly to a vehicle door handle device having a structure for preventing unauthorized unlocking.

2. Description of the Related Art FIG. 4 is a sectional view of a conventional automobile door handle, and FIG. 5 is a partial perspective view of the automobile door handle as seen from the back side. A bracket 1 called an escutcheon is fixed to a door panel (not shown) with a stud bolt 2. It is known to operate a handle 4 rotatably attached to the bracket 1 to open and close the door. An end cover 3 for sealing rainwater or dust is provided on the back side. An arm 4a is formed so as to project from the handle 4, and the arm 4a is inserted through a pair of openings 5 provided in the bracket 1 from the front side to the back side. The arm 4a is rotatably supported by the bracket 1 by a support shaft pin 4b, and the handle 4 is circularly rotated about the support shaft pin 4b.

On the back side of the bracket 1, a swing lever 6 is swingably supported around a spindle pin 7, and is urged clockwise by a spring 8 around the spindle pin 7 in the clockwise direction in FIG. . The other end 6a of the swing lever 6 is in contact with the tip 4c of the arm 4a from above. When the handle 4 is rotated from the front side against the spring 8, the swing lever 6 swings counterclockwise in FIG. 5 by the arm 4a. The swinging motion of the swinging lever 6 is converted into a reciprocating motion of a rod (not shown) connected to the through hole 6c of the most distal end 6b and a door lock device (not shown), so that the rod is opened and closed. Move between. A cylinder lock 9 operated by a key is attached to the bracket 1, and the cylinder lock 9 is connected to a door lock device by an operation rod (not shown). Normally, the cylinder lock 9 is formed near one of the pair of openings 5.

By the way, the opening 5 on the bracket 1 side through which the arm 4a of the handle 4 is inserted is provided in a shape and a size that do not interfere with the arc movement of the arm 4a. Therefore, the arm 4a
A gap is formed between the opening 5 and the opening 5 so that foreign matter or a special tool can be inserted. There has been a crime of illegally unlocking the door by inserting a tool through the gap between the locked opening 5 of the door and the arm 4a to operate the operation rod.

In order to prevent such a crime, there has been proposed an antitheft structure in which the end cover 3 is provided with a shield 3a to prevent the insertion of a tool from the opening 5 formed in the bracket 1.

SUMMARY OF THE INVENTION However, in the foreign matter invasion prevention measure in which the shield 3a is provided on the end cover 3, it is necessary to attach the shield 3a considerably rearward so that the shield 3a does not interfere with the operation of the arm 4a. However, the gap in the door panel is small,
Since the mounting space of the door handle device is restricted, the thickness and depth dimensions of the door handle device cannot be increased so much. Therefore, it is difficult to form the shield portion 3a that largely projects from the bracket 1 on the end cover 3. In addition, the end cover 3 which is usually made of rubber
Since the material is flexible and elastic, it is not possible to secure the rigidity that can sufficiently resist the penetration of tools.

Further, as is apparent from FIG. 4, in order to reduce the gap between the opening 5 formed when the handle 4 is pulled and the arm 4a of the handle 4, the bent portion 4 of the arm 4a is conventionally used.
It was necessary to project d further inward to reduce the gap of the opening 5. When the bent portion 4d of the arm 4a is further extended inward, the shield portion 3a of the end cover 3 is further protruded inward of the door panel.

An object of the present invention is to provide a vehicle door handle device that can effectively prevent the intrusion of tools without increasing the thickness.

Means for Solving the Problems In the vehicle door handle device according to the present invention, the arm of the handle inserted through the opening formed in the bracket is rotatably attached to the bracket. A swing lever is rotatably supported by a spindle pin on the back surface of the bracket. Further, the swing lever is urged in the direction to engage with the arm of the handle by the spring attached to the support shaft pin. The swing lever is operatively connected to the door lock device via the rod, and the rotational movement of the handle is transmitted to the swing lever against the elastic force of the spring.

In this vehicle door handle device, an abutting portion with which the tip of the handle arm abuts is provided on one side of the swing lever. Further, a shield portion extending integrally from the other side portion of the swing lever on the side opposite to the contact portion and extending substantially parallel to the rotation direction of the swing lever is integrally formed. When the handle is rotated in a direction away from the bracket, the shield is moved to a position that substantially closes the opening of the bracket as the swing lever rotates.

In the embodiment of the present invention, a cylinder lock connected to a door lock device is attached to a bracket. A shield is formed on the swing lever so that the opening formed adjacent to the cylinder lock of the pair of openings formed on the bracket can be closed.

When the handle is rotated in the direction away from the bracket,
The swing motion of the arm is transmitted to the swing lever. The shielding portion has a function of rotating together with the swing lever without blocking the movement of the handle, thereby substantially closing the opening portion of the bracket. The shield part moved to the position of closing the opening has a function of sufficiently preventing foreign matter from entering through the opening. In particular,
It is possible to prevent the insertion of the tool from the opening for the purpose of illicit operation of the operation rod. Further, since the contact portion and the shield portion are integrally formed with the swing lever, the structure and manufacturing process of the door handle device can be simplified without increasing the number of parts.

Embodiment An embodiment of the vehicle door handle device according to the present invention will be described below with reference to FIGS.

A handle 20 is arranged on the front side of the bracket 10, and an end cover 30 which is a rubber sealing member is provided on the back side. The bracket 10 is fixed to a door panel (not shown) by a stud bolt 11 that is planted.
An opening 12 is opened at a predetermined position of the bracket 10, and an arm 21 protruding from the handle 20 is inserted into the opening 12. The tip portion 22 of the arm 21 that is pulled out from the opening 12 to the back side of the bracket 10 is formed in an L shape. The arm 21 is attached to the bracket 10 by a support pin 23 near the tip 22 so that the handle 20 can rotate.
Supported by the side.

On the back surface of the bracket 10, a swing lever 14 is swingably supported at one end via a spindle pin 15. A spring 16 is wound around the shaft pin 15, and the spring 16 urges the swing lever 14 around the shaft pin 15 in the clockwise direction. Further, a flat contact portion 14a is formed on one side portion near the tip of the swing lever 14, and the contact portion 1
The tip portion 22 of the arm 21 of the handle 20 is in contact with 4a. Therefore, when the handle 20 is operated by pulling the handle 20 and is rotated around the support shaft pin 23, the arm 21 that makes an arc motion is moved.
The tip end portion 22 of the abutment causes the rocking lever 14 to rock counterclockwise about the spindle pin 15. A rod for operating a latch mechanism (not shown) of the door lock device is connected to the through hole 14c of the most distal end portion 14b of the swing lever 14. A cylinder lock 17 is provided adjacent to the opening 12. An operating rod (not shown) is connected to the cylinder lock 17. The operating rod is connected to the lock mechanism of the door lock device.

The swing lever 14 is provided with a shield portion 14d that integrally extends downward from the other side portion opposite to the contact portion 14a formed on one side portion near the tip. The shield 14d faces the opening 12 of the bracket 10 and is formed in a size and shape that can close the opening 12 substantially. Swing lever 1
4 is formed integrally with the rocking lever 14 from the other side of the rocking lever 14 on the side opposite to the contact portion 14a.
Extends substantially parallel to the direction of rotation of the.

Next, the operation mode and operation of the embodiment having the above configuration will be described.

When the door in the locked state is unlocked illegally, the handle 20 is rotated and the opening 12 of the bracket 10 and the arm 2 are rotated.
The tool is inserted through the gap created between the tool and the tool. At this time,
The arm 21 is swung by the rotation of the handle 20, and the tip portion 22 of the arm 21 swings the swing lever 14 around the support pin 15 against the spring 16. Therefore, when the handle 20 is rotated in the direction away from the bracket 10, the shielding portion 14d moves downward in accordance with the rotation of the swing lever 14, and the opening 12 is substantially closed on the rear surface of the bracket 10. Therefore, the intrusion of the tool inserted into the door panel through the opening 12 is blocked by the shield 14d.

In short, according to the present invention, when the handle 20 is rotated, the swing of the arm 21 is transmitted to the swing lever 14 on the back side of the bracket 10, and the shield portion 14d formed integrally with the swing lever 14 is mounted on the bracket 10. The opening 12 is moved to a position where the opening 12 is almost closed. In this case, when the handle 20 is rotated in the direction away from the bracket 10, the shielding portion 14d has an action of moving together with the swing lever 14 and closing the opening 12 without blocking the movement of the handle 20. . The shielding portion 14d does not move in the thickness direction of the vehicle door handle 20. When the shield 14d moves to a position that closes the opening 12, the shield 14d sufficiently prevents the foreign matter from entering even if the foreign matter enters from the opening 12. In particular, it is possible to prevent the operation rod from being operated by inserting the tool through the opening 12.

As described above, the vehicle door handle device according to the present invention has a crime prevention effect that prevents the occurrence of theft by preventing unauthorized unlocking, and obtains a thin vehicle door handle. You can
