【Example】

 The accompanying drawings are drawings showing a preferred embodiment of the present invention, and FIG. 1 shows a main portion of a wiper device 1 in section. As shown in FIG. 4, the wiper device 1 is configured to be attachable to and detachable from a bracket 3 provided on a stay 21 of a door mirror body 2.

More specifically, the wiper device 1 includes a wiper blade 11 and an arm 12 that supports the wiper blade 11. First, as shown in FIGS. 1 to 3, the wiper blade 11 comprises a blade 11a, a holder 11b, a screw 11c, a bush 11d and a first adjusting screw 11e. The rubber blade 11a is held by the holder 11b and tightened by the screw 11c. ing. The wiper blade 11 has a bush 11d and a slide portion 12a tightened by a first adjusting screw 11e so as to be coupled to a slide portion 12a of an arm 12 described later. At that time, the wiper blade 11 adjusts the angle with respect to the slide portion 12a in the directions of arrows X1 and X2 shown in FIG. 1, and then tightens the first adjusting screw 11e to fix the angle. The angles in the directions of the arrows Y1 and Y2 shown in FIG. 2 are fixed by tightening the screw 11c.

Next, the arm 12 includes a slide portion 12a, a swing portion 12b, and a support portion 12c. The slide portion 12a is, for example, a press-molded metal plate, and the slide portion 12a and the swing portion 12b are fastened by the second adjusting screw 12d so as to be coupled to the swing portion 12b. At that time, the slide portion 12a adjusts its position with respect to the swing portion 12b in the directions of arrows L1 and L2 shown in FIG. 1, and then tightens the second adjusting screw 12d to fix the position.

The swing portion 12b is, for example, a die-cast metal material, and has a slit 12e and a joint hole 12f. Then, the slit 12e is fitted with the above-mentioned second adjusting screw 12d, and the joint hole 12f is provided with the joint hole 12f and the rod 12g of the supporting portion 12c, which will be described later, so as to connect the swing portion 12b to the supporting portion 12c. It is tightened by the adjusting screw 12h. At this time, the swing part 12b adjusts the angle with respect to the support part 12c in the directions of arrows Z1 and Z2 shown in FIG. 1, and then tightens the third adjusting screw 12h to fix the angle.

The support portion 12c includes a rod 12g, a return spring 12i, a hole 12j, a screw 12k, a base 12l, a lock release button 12m, a lock claw 12n, a fitting groove 12o and a cover 12q. The rod 12g is rotatably fitted in the hole 12j of the base 12l and is prevented from coming off by a screw 12k. The return spring 12i has one end fixed to the rod 12g and the other end fixed to the base 12l to elastically return the rod 12g to a predetermined rotation angle. The fitting groove 12o is for fitting a fitting portion 3a of the bracket 3 described later. The lock claw 12n is elastically fitted in the lock hole 3b of the same bracket 3. Further, the lock release button 12m is for pushing up the lock claw 12n by a pushing operation to remove the bracket 3 from the lock hole 3b.

Next, the door mirror main body 2 is an existing one, and a stay 21 for attaching the door mirror main body 2 to a vehicle door (not shown), and a mirror surface 22 whose tilt can be adjusted from the passenger compartment. The door mirror body 2 has a rotating shaft portion 23 serving as a fulcrum for rotating the door mirror body 2 between a storage position and an operating position. The bracket 3 for attaching and detaching the wiper device 1 is fastened together with, for example, a screw (not shown) for fixing the stay 21 to the door. The bracket 3 is formed by pressing a metal plate, for example, and has a push-up portion 3c and a step portion 3d in addition to the fitting portion 3a and the lock hole 3b. The push-up portion 3c functions to push up the lock claw 12n when the fitting portion 3a of the bracket 3 is inserted into the fitting groove 12o of the wiper device 1. The stepped portion 3d contacts the opening end 12p of the fitting groove 12o when the lock claw 12n is completely fitted into the lock hole 3b of the bracket 3 and plays a role of fixing the support portion 12c to the bracket 3. Although the elastic fitting means, that is, the lock claw 12n is provided on the wiper device 1 side in the embodiment, the elastic fitting means may be provided on the bracket 3.

Next, the operation will be described. When the wiper device 1 is mounted on the bracket 3, first, the fitting portion 3a of the fitting groove 12o of the support portion 12c is inserted, and the support portion 12c is pushed in the direction of arrow B shown in FIG. It abuts on the push-up portion 3c of the bracket 3 and is lifted. When the support portion 12c is further pushed in the direction of the arrow B, the lock claw 12n falls into the lock hole 3b of the bracket 3 and is fitted therein, as shown in FIG. Then, the wiper device 1 is completely attached to the door mirror body 2 as shown in FIG.

Next, when the mirror surface 22 of the door mirror body 2 is wiped by the wiper device 1, for example, an occupant of the vehicle operates a switch, and the door mirror body 2 is removed by an actuator (not shown) built in the door mirror body 2. A rotation operation is performed in the directions of arrows C1 and C2 between the operating position indicated by the solid line in FIG. 4 and the storage position indicated by the virtual line. Then, the wiper blade 11 of the wiper device 1 slides on the mirror surface 22 in the directions of arrows D1 and D2 to wipe the mirror surface 22. Thus, the wiper device 1 removes water droplets and the like attached to the mirror surface 22 as the door mirror 2 rotates.

Next, when removing the wiper device 1 from the bracket 3, first, the lock release button 12m is pushed in the direction of arrow E shown in FIG. 8 to remove the lock claw 12n from the lock hole 3b of the bracket 3. Then, the support portion 12c is pulled in the direction of the arrow F shown in FIG. 8, and the support portion 12c is pulled out from the bracket 3. Then, the wiper device 1 completes the removal from the door mirror body 2.

[0014]

[Effects of the Invention] According to the present invention, the wiper device can be freely attached to the existing door mirror body due to the above-described constitutional effect, so that there is no need to replace the door mirror body with a new one, and the economical effect is remarkable. is there. Also, since the wiper device can be attached and detached with one touch, it is easy to repair when the wiper device is damaged, and it has the convenience of being able to repair it by a vehicle owned by a vehicle without specialized knowledge. . Furthermore, when cleaning the vehicle, the wiper device can be easily removed, so that the wiper device does not interfere with the cleaning work. Furthermore, by providing an adjusting screw as shown in the embodiment, it is possible to secure an optimum posture for various types of door mirror main bodies.
