BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door outside handle device.

[0002]

2. Description of the Related Art As a door outside handle device equipped with a counterweight, a device disclosed in Japanese Utility Model Publication No. 3-32196 is known. In this conventional example, the counterweight is fixed to the handle body pivotally supported by the handle case, and the inertial force generated in the handle body when an impact force is applied to the door is canceled by the counterweight to open the handle body in the operating direction. Regulate movement to.

[0003]

However, the above-mentioned conventional example requires a support shaft for connecting the handle body to the handle case, in addition to a pin or the like for fixing the counterweight to the handle body. There is a drawback that many parts are wasted.

The present invention has been made to solve the above drawbacks, and an object of the present invention is to provide a vehicle door outside handle device capable of reducing the number of parts.

The tongue 6 that touches and prohibits the movement of the pivot pin 4 in the pulling direction
This is achieved by providing a vehicle door outside handle device having a protruding counterweight 1 .

The counterweight 1 connected to the handle body 2 has a pivot pin 4, and the handle body 2 and the handle case 3 are rotatable by inserting the pivot pin 4 into the handle body 2 and the handle case 3. Connect to. Since the pivot pin 4 for connecting the handle case 3 and the handle main body 2 is integrally formed on the counterweight 1, a separate support shaft for pivotally supporting the handle main body 2 is not required for the handle case 3, and the number of parts is reduced. Decrease.

[0007] The handle body 2 and the counterweight 1 is also connected using caulking or connecting pins or the like,
However, the handle body 2 and the counterweight 1 can be connected by engaging with each other.

That is, the counterweight 1 is engaged with the handle body 2 when the pivot pin 4 is moved in the longitudinal direction of the handle body 2 and the handle case 3 in the longitudinal direction thereof. Since the engaging direction of the counterweight 1 and the handle body 2, that is, the inserting direction of the pivot pin 4 is orthogonal to the rotating direction of the handle body 2,
With respect to the rotating direction of the handle main body 2, the same effect as that of being integrally fixed is exhibited.

As a retaining means 5 for preventing detachment of the counterweight 1, that is, detachment of the handle main body 2 from the handle case 3 against a load of impact force from the front or the rear of the vehicle, a pivot shaft is used. Caulking on pin 4 can be used. Further, the leg portion 11a of the torsion spring 11 mounted between the handle body 2 and the handle case 3 can be used as the retaining means 5, and in this case, for example, as shown in FIG. By locking the portion 11a to the counterweight 1, it is possible to prevent the counterweight 1 from moving in the detaching direction of the pivot pin 4.

[0010]

The mounting of the counterweight 1, that is, the connection between the handle body 2 and the handle case 3 is performed with the counterweight 1 in the insertion direction of the pivot pin 4 with the handle body 2 overstroked beyond the stroke end in the opening direction. It is done by moving. At the overstroke position of the handle body 2, the tongue piece 6 of the counterweight 1 can pass over the slide restricting piece 7 of the handle case 3, and when the handle body 2 returns to the initial position thereafter, the slide restricting piece 7 will move to the tongue piece 6. The counterweight 1 is prevented from coming off by prohibiting the movement of.

Therefore, when the counterweight 1 is attached to the handle main body 2 and the handle main body 2 is attached to the handle case 3, no caulking or the like is used, and neither a fixing pin nor a support shaft is required. Moreover, the assembly workability is improved and the number of parts is reduced.
Further, since the over-stroke operation of the handle body 2 is prohibited by the stopper piece 10 after the assembly, the counterweight 1 does not drop out by the user's operation.
In addition, since the stopper piece 10 is integrally formed with the end cover 9 that is mounted after the handle body 2 is attached to the handle case 3, no special parts are required and the assembly workability is not deteriorated. .

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIGS. 1 to 4, a vehicle outside door handle device includes a handle case 3 fixed to a vehicle door panel 8 and an interposition between the handle case 3 and the door panel 8. End cover 9
And a handle body 2 rotatably supported by the handle case 3.

The handle case 3 is formed in a dish shape by recessing a handle accommodating recess 3a in the center of the front surface, and two arms 3b, 3b and a slide restricting piece 7 are provided on the rear surface so as to project. The arms 3b are arranged at the left and right ends of the handle case 3,
The slide restricting piece 7 is arranged substantially in the center thereof. A hinge hole 3c is formed in each arm 3b at an opposing position.

The handle main body 2 has a handle portion 2b which is accommodated in the handle accommodating recess 3a, and on the back surface of the handle portion 2b, there are two pieces extending from the arm insertion opening 3d formed in the handle case 3 to the rear surface of the handle case 3. Arm 2a of
2a is projected. A hinge hole 2c facing the hinge hole 3c of the handle case 3 is bored at the center of each arm 2a. The arm 2a of the handle body 2 is further extended, and weight holding portions 12 and 12 'are formed at the tip end portion thereof. One of the weight holding portions 12 and 12 'is formed in a semicircular cutout shape and the other is formed in a perfect circular through hole shape. The weight holding portions 12 and 12' have a weight of the counterweight 1 and a mounting posture of the handle case 3 described later between the weight holding portions 12 and 12 '. The distance L is set taking into consideration (see FIG. 2).

The counterweight 1 is formed of a metal material having a large specific gravity, and is preferably formed of a die casting alloy having excellent workability and formability. The counterweight 1 has a solid rod-shaped weight portion 1a on the center of which a tongue piece 6 that cooperates with a slide regulating piece 7 to be described later and that constitutes a retaining means 5 is projected. At one end, a weight holding portion 1 of the above-mentioned handle body 2 in the shape of a perfect circular hole is formed.
A connecting pin 1b that can be inserted into 2'is provided in a protruding manner. Further, hanging pieces 1c are hung at both ends of the weight portion 1a, and pivot pins 4 are provided at the free ends of the hanging pieces 1c so as to project. The pivot pin 4 is arranged in parallel with the weight portion 1a, and protrudes in the protruding direction of the connecting pin 1b.

Assembly of the handle case 3, the handle body 2, and the counterweight 1 is performed as follows. First, after inserting the arm 2a of the handle body 2 into the arm insertion opening 3d of the handle case 3, the hinge hole 2c is aligned with the hinge hole 3c of the handle case, and the handle body 2 is held in the posture shown in FIG. That is, it is held in a state of being rotated to the limit position in the opening operation direction. In this state, the handle body 2 is in the overstroke posture beyond the end of the rotation stroke in the normal opening operation direction, which will be described later. In this state, the counterweight 1 connects the handle body 2 to the handle case 3. As shown in FIG. 1, the connection of the handle body 2 by the counterweight 1 allows the pivot pin 4 of the counterweight 1 to correspond to the handle case 3 and the hinge holes 3c, 2c of the arms 3b, 2a of the handle body 2, and After fitting the weight portion 1a of the counterweight 1 to the semicircular cutout-shaped weight holding portion 12 of the handle main body 2, as shown by the arrow in FIG.
This can be easily performed by moving the weight portion 1a in the longitudinal direction. As shown in FIG. 3A, in the overstroke state, the tongue piece 6 of the counterweight 1 can be moved laterally without interfering with the slide restricting piece 7 of the handle case 3, and from this state, the counterweight 1 When the sliding operation is performed, the weight portion 1a of the counterweight 1 slides along the semicircular cutout weight holding portion 12 of the handle body 2, and the connecting pin 1b holds the weight of the handle body 2 in the shape of a perfect circular hole. It is inserted into the portion 12 ′ and connected to the handle body 2.

After that, the torsion spring 11 is arranged between the slide restricting piece 7 of the handle case 3 and the arm 3b, and one leg portion 11a is brought into contact with the back wall of the handle case 3 while the other leg is held. Spring locking groove 1d in which the portion 11a is formed in the weight portion 1a of the counterweight 1.
The initial torsion is applied to the torsion spring 11 by locking it. With the torsion spring 11 attached, the handle body 2 is biased toward the initial position (the position where the handhold 2b is accommodated in the handle accommodating recess 3a of the handle case 3 as shown in FIG. 3A). At the initial position, the tongue piece 6 of the counterweight 1 comes into contact with the slide regulation piece 7 of the handle case 3 to form an overlapping portion 13 in a side view as shown in FIG. To be done. The overlapping portion 13 is maintained at least within the rotation range of the handle body 2 from the initial position to the stroke end position in the opening operation direction described later, and the counterweight 1 is prohibited from moving in the sliding direction.

The end cover 9 is made of a synthetic resin material and is attached to the handle case 3 prior to the attachment of the handle device to the door panel 8. A stopper piece 10 is provided on the end cover 9, and as shown by hatching in FIG. 3B, it is fitted and held on the upper end portion of the arm insertion opening 3d of the handle case 3 when mounted on the handle case 3. To be done. By connecting the handle main body 2 to the handle case 3 and fitting the stopper piece 10 into the arm insertion opening 3d, the movement range of the arm 2a of the handle main body 2 is restricted, and as a result, the handle main body 2 is moved to the position shown in FIG.
From the initial position shown in (a), as shown in FIG.
The arm 2a of the handle main body 2 can rotate up to the stroke end position on the opening operation side where the stopper piece 10 abuts. The surface of the stopper piece 10 coincides with the surface of the handle case 3 so that the stopper piece 10 is fitted into the arm insertion opening 3d without causing an unnatural appearance.

Therefore, in this embodiment, the handle portion 2b is pulled up in the direction of the arrow in FIG. 4 (a) against the reaction force of the torsion spring 11 and the handle body 2 is pulled up.
By rotating to the opening operation side, the rod (not shown) connected to the arm 2a of the handle body 2 via the holder 14 can be operated, and the lock device arranged in the door body can be operated. The counterweight 1 is connected to the handle body 2 and the weight portion 1a is located at a position separated from the center of rotation of the handle body 2 by a predetermined distance L. Therefore, when an impact load is applied from the side of the vehicle, The inertial force of the weight portion 1a cancels out the inertial force of the handle main body 2 in the door opening direction, so that careless opening of the door is prevented. Further, even if the handle body 2 is rotated to the open side stroke exclamation position, the overlapping portion 1 as shown in FIG.
Since 3 is maintained, the counterweight 1 will not be detached.

In the illustrated example, the weight 1a of the counterweight 1 has a connecting pin 1b protruding from one end and the other end of the weight 1a is attached to the weight holding portion 1 of the handle body 2.
The case of inserting and fitting in 2'and 12 is shown, but the connecting pin 1b is projectingly provided in both hanging pieces 1c in the same direction as the projecting direction of the pivot pin 4, and the through hole-like shape provided in the handle body 2 is formed. It can also be inserted into the weight holder 12.
