Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a door outside handle device for a motor vehicle.

[0002]

2. Description of the Related Art As a door outside handle device for preventing water from entering the inside of a door body at the time of car washing or the like, one disclosed in Japanese Utility Model Publication No. 1-16833 is known. In this conventional example, as shown in FIG. 5, the periphery of an arm insertion hole 5 formed in the handle case 2 for inserting the arm 4 of the handle main body 3 is closed with water penetrating from the arm insertion hole 5. A cover 7 for stopping is provided.

[0003]

However, in the above-mentioned conventional example, a certain effect can be expected when the water pressure is weak.
For example, when the water is strong such as in a car wash using a hose, especially when water is sprayed from below the handle main body 3 as shown by an arrow in FIG. 5, the following problem occurs. That is, water blown by a hose or the like from below the handle body 3 at the time of car washing is spouted vigorously from the upper open portion 7a of the cover 7 and is sprayed to the inner panel 12 side. If the boundary between the inner panel 12 and the window glass 13 or the boundary between the window glass 13 and the inner trim is located near the blowout site, water may intrude into the room over the boundary.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a door outside handle device for an automobile which can surely prevent water from flowing into a room through which water can enter.

[0005]

SUMMARY OF THE INVENTION According to the present invention, an object of the present invention is to provide a door outside handle device for a vehicle, wherein a handle body 3 is rotatably supported on a handle case 2 fixed to a door panel 1 of the vehicle. In addition, a cover 7 including a waterproof wall surface 6 is projected from the periphery of an arm insertion hole 5 formed in the handle case 2 toward the rear surface so as to allow the arm 4 of the handle body 3 to pass therethrough. 4 is provided by providing a door outside handle device of an automobile in which an eave 8 that protrudes from above to cover a gap between the waterproof wall surface 6 and the arm 4 is provided.

The cover 7 provided on the back surface of the handle body 3 has a waterproof wall surface 6, and water entering through a gap formed between the arm insertion hole 5 formed in the handle case 2 and the handle body 3. Is prevented from directly spraying on the inner panel 12. A strong water flow like a car wash with a hose collides with the waterproof wall surface 6, moves upward along the waterproof wall surface 6, overflows from the upper end of the waterproof wall surface 6,
It flows out in the direction determined by the eaves 8.

Therefore, in the present invention, since the direction of water flow can be changed by the eaves 8, a water leakable path into the room, such as a boundary between the inner panel 12 and the window glass 13, is formed in the arm insertion hole 5 of the handle case 2. In the case where it is arranged in the vicinity, it is possible to prevent the water from leaking into the room at the time of car washing by changing the water flow in a direction other than the leakable path.

In this case, as in the invention according to claim 2,
When the ceiling surface 9 of the eaves 8 is an inclined surface approaching the waterproof wall surface 6 toward the tip, the jet colliding with the eaves 8 is turned by the ceiling surface 9 of the eaves 8 to the arm 4 side of the handle body 3. After that, the jet falls down along the wall surface of the arm 4, so that the flying range of the jet becomes narrow.

Further, when the concave groove 10 is provided in the arm 4 as in the invention according to the third aspect, the cross-sectional area of the jet flow becomes large, so that the flow velocity can be reduced and the eaves can be reduced. Since the diverted flow at 8 and the water flow rising along the waterproof wall 6 collide in the water channel and become turbulent, the speed of the water flow going upward can be reduced.

[0010] In addition, when the drainage opening 11 is opened at the base end of the waterproof wall surface 6 as in the invention according to claim 4, the downward flow can be positively drained downward, so that the upward flow is performed. The amount of water going can be reduced.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 to 3, a door outside handle device for an automobile has a handle case 2 formed in a dish shape by recessing a handle accommodating recess 2a at the center of the surface. The handle body 3 is rotatably supported by the handle body 2.

The handle body 3 has a handle portion 3a housed in the handle housing recess 2a of the handle case 2, and an arm 4 extending through the arm insertion hole 5 formed in the handle case 2 and extending to the back side of the handle case 2. Having. A pivot 14 is inserted between the arm 4 and the arm 4 of the handle case 2, and the handle body 3 is rotatable around the pivot 14 with respect to the handle case 2. A torsion spring 15 is wound around the pivot 14, and holds the handle main body 3 in the initial posture shown in FIG. Further, the arm 4 of the handle body 3 is further extended, and a counter weight 16 for restricting the opening operation of the handle body 3 when an impact load is applied is fixed to the tip thereof. It should be noted that in FIGS.
Indicates a clip for fixing the counterweight 16 to the arm 4 of the handle body 3.

With the above structure, the torsion spring 1
5 shows the handle 3a of the handle body 3 against the reaction force of FIG.
When the handle body 3 is rotated by pulling it out in the direction of the arrow, a rod (not shown) connected to the handle body 3 via the holder 18 operates as shown in FIG. The device can be activated.

A cover 7 is provided on the back of the handle case 2.
Is protruded. The cover 7 has side wall surfaces 7b and 7b whose base ends are both side edges of the arm insertion hole 5, and a waterproof wall surface 6 whose base end is the lower edge of the arm insertion hole 5 and is continuous with both side wall surfaces 7b. The waterproof wall surface 6 is set up substantially in parallel with the door panel 1, and the upper edge 6 a is set at a height that does not interfere with a rotation locus 8 a of the eave 8 described later when the handle body 3 rotates.
Further, a drain opening 11 is formed at the base end of the waterproof wall surface 6.

On the other hand, the handle body 3 is provided with an eave 8 protruding from the back of the arm 4. The protruding dimension of the eaves 8 is
The lower edge of the eaves 8 substantially coincides with the projecting dimension of the waterproof wall surface 6, and is located on a vertical extension line from the upper end of the waterproof wall surface 6. In addition, the ceiling surface 9 of the eaves 8 is an inclined surface whose height gradually decreases toward the rear.

Further, a concave groove 10 is formed in the arm 4 of the handle body 3. The concave groove 10 is formed by recessing the central portion of the rear wall of the arm 4 along the extending direction of the arm 4 so as to face the waterproof wall surface 6. , An inclined surface 10a having a gradually lower height is formed. Further, a small ridge 10b is formed at the lower end of the concave groove 10. The upper surface of the small ridge 10b is an inclined surface whose height gradually decreases as it goes backward, and the drainage opening 11 is arranged on an extension of the inclined surface.

Therefore, in this embodiment, the arm 4 of the handle body 3 is covered by the cover 7 at the portion where the arm 4 is inserted into the arm insertion hole 5 of the handle case 2. Water sprayed from below the handle portion 3a of the handle main body 3 during a car wash using a hose or the like flows along the bottom wall and the side wall of the arm 4 of the handle main body 3 as shown by an arrow A in FIG. After flowing out in the rear direction, it is guided to the running water space 19 surrounded by the cover 7 and collides with the waterproof wall surface 6. Part of the impinging water flow on the waterproof wall 6 is a drain opening 11.
As shown by an arrow B, the remaining portion rises along the waterproof wall surface 6 and collides with the eaves 8 arranged so as to cover the flowing water space 19 from above in the initial posture. The water flow impinging on the eaves 8 is turned downward by the ceiling surface 9 of the eaves 8 and the inclined surface 10a at the base end of the eaves 8 as shown by the arrow C, and then descends along the concave groove 10,
The direction is changed again by the inclined surface of the upper surface of the small ridge 10b, and flows downward from the drainage opening 11. As a result, even if a path that allows water to enter the room is disposed at the upper rear part of the arm 4, water can be reliably prevented from entering the path.

In the above embodiment, the waterproof wall surface 6 is disposed along the rear wall of the handle body 3 in a posture parallel to the door panel 1, but as shown in FIG. It is possible to bend the handle body 3 side inwardly from the rear end of the eave 8. With this configuration, the flow velocity can be suppressed, and the gap between the side wall 7 b and the arm 4 can be reduced. Water leakage can be prevented. Further, the cover 7 has the side wall surface 7b surrounding the side wall portion of the arm 4 of the handle main body 3, but may be constituted only by the waterproof wall surface 6.

[0019]

As is apparent from the above description, according to the present invention, it is possible to reliably prevent water from being sprayed into the room through which water can enter.
