DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer handle device used for a side door of an automobile.

[0002]

2. Description of the Related Art Generally, an outer handle provided on a side door of an automobile has a structure capable of preventing the door from being opened due to a 30G impact due to legal restrictions. Is required.

Conventionally, as a structure capable of preventing the rotation of the outer handle, for example, in a case of a die-cast outer handle, a separate balancer is provided so that the center of gravity is located near the center of rotation of the outer handle. There is a type that increases the spring force of a spring that urges the outer handle toward the door body. However, the former structure has a problem that the weight becomes too large, and the latter structure has a problem that it is difficult to operate the outer handle due to a large urging force due to a spring force.

[0004] Further, there is a type in which the outer handle is made of resin to reduce the weight and reduce the inertial force to prevent the door from being opened by an impact. However, in this structure, the strength and rigidity are not sufficient in comparison with the die-cast structure, so that the structure is easily broken, and furthermore, the appearance is poor.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide an outer handle device which is not inferior in strength, rigidity and appearance, has good operability, and can prevent the door from being opened by an impact.

[0006]

According to the present invention, in order to achieve the above object, an opening handle rotatably mounted on a base provided on a door body has a smaller weight and a guide than an opening handle. A sub-handle having a pin is rotatably provided so as to be operated simultaneously with the operation of the opening handle, while the guide pin is operated on the base by operating the sub-handle before operating the opening handle. A guide groove comprising a sliding lock groove and an opening groove in which the guide pin slides by operating the opening handle while operating the sub-handle is formed.

[0007]

According to the present invention, the guide pin of the sub-handle is locked in the locking groove of the guide groove, and the rotation is prevented even if the opening handle tries to rotate due to an impact force. By operating the sub-handle before operating the opening handle, the guide pin slides on the locking groove of the guide groove and is positioned at one end of the opening groove. Thereafter, by operating the opening handle together with the sub handle, the guide pin slides in the opening groove, and the door is opened.

[0008]

Next, an embodiment of an outer handle device according to the present invention will be described with reference to FIGS.
As shown in FIG. 1, the outer handle device includes a base 2 provided on a door body 1, an opening handle 3 attached to the base 2, and a sub-handle 4 attached to the opening handle 3.

The opening handle 3 is a die-cast casting made of a zinc alloy or the like, and includes a flat plate portion 5 exposed on the outer surface of the door body 1 and arms 6a and 6b integrated with both ends of the rear surface of the flat plate portion 5. It is configured. The flat plate portion 5
A projection 7 is provided at the center of the back surface of the, and a spring 8 is inserted through the projection 7. A shaft portion 9 is provided in the longitudinal direction on the upper surface of the rear surface of the flat plate portion 5. The two arms 6a, 6b are connected to the following bearings 18a,
It is rotatably attached to a support shaft 19 inserted through 18b and 18c. One arm 6a extends further upward, and is connected to a rod 10 for driving a door lock device for opening a door. A spring 20 is inserted through the support shaft 19. One end of the spring 20 is locked by the bearing portion 18c, and the other end of the spring 20 presses the arm portion 6a, thereby urging the opening handle 3 clockwise about the support shaft 19 in FIG. ing.

The sub-handle 4 is a lightweight plate made of synthetic resin and is rotatably mounted on the shaft 9 of the opening handle 3 so as to rotate together with the opening handle 3. The sub handle 4
Is biased clockwise about the shaft 9 in FIG. 2 by the spring 8. Both ends of the sub handle 4 are extended portions 11a and 11b extending in a substantially triangular shape on the back side, and the extended portions 11a and 11b are provided.
Guide pins 12a and 12b project outward from the corners of b in parallel with the shaft 9 (see FIG. 3). Further, notches 13a, 13b are formed in the sub-handle 4 so that the arms 6a, 6b of the opening handle 3 can rotate.

The base 2 is formed by forming a metal plate into a recess 2a.
It is easy to put a hand in the recess 2a and put a finger on the sub-handle 4. The locking groove 1 is provided on a side wall 14 facing at both ends of the recess 2a.
Guide grooves 15 each including a groove 6 and an opening groove 17 are formed. The locking groove 16 is formed in an arc shape having a center at the shaft 9 at a position where the opening handle 3 is not operated and having a radius corresponding to the shortest distance between the shaft 9 and the guide pins 12a and 12b. , Sub handle 4
Is provided in a range where the guide pins 12a and 12b slide when the is rotated. Further, the opening groove 17 is formed in an arc shape with the radius being the shortest distance between the support shaft 19 and the guide pins 12a and 12b at the position where the sub-handle 4 is operated, with the support shaft 19 being the center. When the opening handle 3 rotates together with the sub handle 4, the guide pin 1
2a and 12b are provided in a slidable range. The ends of the grooves 16 and 17 communicate with each other so that the guide pins 12 a and 12 b can slide between the grooves 16 and 17. Reference numeral 15a denotes a locking recess, and the guide pin 1 is rotated by rotating only the opening handle 3.
2a and 12b are formed to be locked. However, the locking recess 15a is not always necessary.

Next, the operation of the outer handle device configured as described above will be described. First, a finger is inserted into the recess 2 a of the base 2 and hooked on the lower end of the sub handle 4. When the sub-handle 4 is pulled, the sub-handle 4 rotates counterclockwise around the shaft 9 in FIG. 2 and continues to rotate until it comes into contact with the back surface of the opening handle 3. During this time, the guide pins 12a, 12b
Slides in the locking groove 16 until it is located at one end of the opening groove 17. Therefore, when the sub-handle 4 is further pulled, the opening handle 3 starts to rotate counterclockwise about the support shaft 19 while the guide pins 12a and 12b slide in the opening groove 17 (see FIG. As a result, a door lock device (not shown) operates via the rod 10 to open the door.

In the outer handle device, when an impact force is applied due to an accident or the like with the door closed, an inertial force acts on the opening handle 3 and the sub-handle 4 toward the outside of the door body 1. . But,
Since the sub handle 4 is made of a lightweight resin material,
The acting inertial force is small and hardly rotates. In addition, the guide pins 12a and 12b are locked in the locking recesses 15a as the opening handle 3 tries to rotate by inertia force, so that the guide pins 12a and 12b cannot escape from the locking groove 16. Therefore, the opening handle 3 is provided with the guide pin 12
The rotation of the door is prevented by the locking groove 16 through the holes a and 12b, and the door is kept closed.

[0014]

As is apparent from the above description, according to the outer handle device according to the present invention, the guide pin projecting from the lightweight sub-handle interlocking with the opening handle is locked by the guide groove formed in the base. The door is prevented from opening due to an impact by locking it in the groove for use, so even if a die-casting opening handle with excellent strength, rigidity and appearance is used, a balancer should be provided or the spring should be strengthened. It is not necessary to perform the operation, and it is lightweight and operability can be improved.
