【Example】

 Hereinafter, an embodiment of an outside door handle for a vehicle according to the present invention will be described with reference to FIGS. In these drawings, parts that are substantially the same as the parts shown in FIGS. 5 to 7 are given the same reference numerals, and description thereof will be omitted. As shown in FIGS. 1 and 2, the outside door handle for an automobile according to the present invention has an escutcheon 20 fixed to a door panel 40 by a stud bolt 21, a hinge pin 1 provided on the escutcheon 20, and a hinge pin 1 as a fulcrum. Thus, the door handle body 10 rotatably attached, the spring 50 for pressing the door handle body 10 toward the escutcheon 20, the end cover 30 arranged between the door panel 40 and the escutcheon 20, and the escutcheon 20. And a switch device 60 attached to the.

As shown in FIG. 1, the hinge pin 1 is bent in a U-shape to form a support portion 2 and a movable portion 3. The door handle body 10 is rotatably supported by the escutcheon 20 by the support portion 2 of the hinge pin 1. The door handle body 10 and the escutcheon 20 are metal die-cast molded products such as zinc or molded products made of synthetic resin such as polyacetal resin. A pair of arm portions 11 and 11 are formed on the left and right sides of the back surface of the door handle body 10, and are inserted into holes 24 and 24 formed in the escutcheon 20 and project to the back surface of the escutcheon 20. A pair of support shaft arms 22 and 22 are formed on the back surface of the escutcheon 20, and the support shaft arms 22 and 22 are connected to the arm parts 11 and 11 of the door handle body 10. Therefore, the door handle body 10 pivotally attached to the escutcheon 20 is rotatable with respect to the escutcheon 20 in the direction indicated by the arrow D in FIG. The escutcheon 20 is formed with a recess 23 that is recessed inside the door panel 40. The recessed portion 23 serves as an escape portion into which a hand can be put when the door handle body 10 is gripped. An end cover 30 made of synthetic rubber is interposed between the escutcheon 20 and the door panel 40 to prevent water from entering the door panel 40 and reduce the impact generated when the door handle body 10 is manually operated. There is.

As shown in FIG. 2, an engaging recess 12 is formed in one arm portion 11 of the door handle body 10 to lock the movable portion 3 of the hinge pin 1. Therefore, the movable portion 3 of the hinge pin 1 can be rotated in conjunction with the rotation operation of the door handle body 10. Further, as shown in FIGS. 1 and 3, the movable portion 3 of the hinge pin 1 is formed with a locking portion 4 by bending, and has a coil shape mounted around the shaft of the support portion 2 of the hinge pin 1. One end 51 of the spring 50 is locked. Therefore, the movable portion 3 of the hinge pin 1 is biased by the one end portion 51 of the spring 50, so that the door handle body 10 can be biased toward the escutcheon 20 side. Further, the locking portion 4 has a function of preventing the hinge pin 1 from coming off. As is well known, the door can be opened by pulling the door handle body 10 forward against the spring 50. The other end 52 of the spring 50 is a free end that extends downward adjacent to the back surface of the bulging recess 23 of the escutcheon 20.

As shown in FIG. 1, a switch device 60 having a leaf spring member 62 is mounted on the back surface of the escutcheon 20. As shown in FIG. 3, the leaf spring member 62 is elastically pressed by the movable portion 3 of the hinge pin 1 that is locked to one arm portion 11 of the door handle body 10 to electrically switch the switch device 60. It can be turned on and off. As shown in FIG. 1, the wiring 63 led out from the switch device 60 is connected to electric components such as a keyhole lighting device 65 and a vehicle-mounted power supply battery (not shown).

Further, a mounting cylinder portion 64 for accommodating a cylinder lock (not shown) is formed on the back surface of the escutcheon 20. Although not shown in detail, the keyhole lighting device 65 is electrically connected to the mounting cylinder portion 64. Connected. A key insertion hole is provided on the front side of the escutcheon 20, and the periphery of the key insertion hole is illuminated by the keyhole lighting device 65 at night. The lock is locked or unlocked by key operation, and the door is locked and unlocked.

Next, the operation of the embodiment will be described with reference to FIGS. When the door handle body 10 is pulled toward the front against the spring 50 shown in FIG. 3, one arm portion 11 of the door handle body 10 rotates in the direction of the arrow R in FIG. The movable portion 3 of the hinge pin 1 locked in the fitting recess 12 is rotated. After that, as shown in FIGS. 3 and 4, the movable portion 3 of the hinge pin 1 presses the leaf spring member 62 of the switch device 60 to activate the switch device 60. As described above, in this embodiment, since the switch device 60 can be operated by the U-shaped hinge pin 1, the structure can be simplified and the number of parts and the manufacturing cost can be reduced. You can

The embodiment of the present invention is not limited to the above-mentioned embodiment, and can be modified. For example, in the above-described embodiment, the example in which the movable portion 3 of the hinge pin 1 is biased by the one end portion 51 of the spring 50 is shown, but the movable portion 3 of the hinge pin 1 is connected to the one arm portion 11 of the door handle body 10. Alternatively, one arm portion 11 of the spring 50 may be biased by one end portion 51 of the spring 50. Further, in the above embodiment, the example in which the synthetic rubber end cover 30 is interposed between the escutcheon 20 and the door panel 40 is shown, but the escutcheon 20 and the door panel 40 are fixed without a gap and the end cover 30 is eliminated. You may.
