JP 2003-191790 A

In the conventional antiglare mirror mounting device, the antiglare mirror may vibrate. When the inventor investigated the cause, it was found that vibration was likely to occur in the bracket portion. In particular, as a bracket for an antiglare mirror, it is required that a part of the bracket is elastically deformable for changing the angle. Therefore, a synthetic resin material that can be deformed to some extent is used, and it cannot be made rigid. In fact, it is difficult to reduce vibration with the bracket itself.
Recently, it has been considered that anti-glare mirrors have built-in components such as ETC on-board units. In this case, the weight applied to the bracket is increased, vibration is increased, and the bracket is easily deformed. There is a concern that the anti-glare mirror support form may deviate from the normal state.

As a countermeasure, there is a structure in which a reinforcing plate made of a metal plate made of, for example, a flat plate is attached to the front surface of the bracket. However, in this case, the front surface of the bracket is not necessarily flat, that is, the pressing force of the reinforcing plate does not always act on the entire front surface of the bracket, and is effective in reducing vibration of the antiglare mirror and preventing deformation of the bracket. The fact was that it was not functioning properly.
The present invention has been made in view of the above circumstances, and an object thereof is to provide an anti-glare mirror mounting device that can suppress the occurrence of vibrations of the anti-glare mirror and prevent deformation of the bracket.

To achieve the above object, a first aspect of the present invention is a bracket made of a synthetic resin for mounting a stay attached to a vehicle body and a mirror housing of an anti-glare mirror attached to the tip of the stay so that the angle of the mirror housing can be changed. And a reinforcing plate attached to the bracket , wherein the bracket has a hole, and the stay has a rotation holding member with a female screw portion formed at the tip thereof . At least both end portions of the convex portion provided on Rutotomoni, the portion located between the protrusions of the both sides, to form a screw insertion hole, the Atamazuke screw through the hole and the screw insertion hole by screwing the female thread portion of the rotating holding member of the stay, in the form of pressing the protrusion into the bracket, and a portion between the both sides of the convex portions in the reinforcing plate attached to the bracket Having the features in place.

According to the first aspect of the present invention, since the convex portion of the reinforcing plate is pressed against the bracket, the portion between the convex portions on both sides of the reinforcing plate is coupled to the bracket. Even if the reinforcing plate mounting surface is not somewhat flat, the convex portions at both end portions of the reinforcing plate will strongly press both sides of the bracket, and the reaction force of the pressing force at the joint between the convex portions on both sides As a result, the reinforcing force (pressing force) of the reinforcing plate with respect to the bracket extends over almost the entire area of the bracket, so that the rigidity of the bracket can be increased and the occurrence of vibration can be suppressed, and the deformation of the bracket can be suppressed. In general, the antiglare mirror can be attached without vibration and in an appropriate posture.
In addition, by a simple assembly in which the reinforcing plate is attached to the bracket with a head screw, it is possible to obtain a strong pressing action on the bracket by the convex portion, and the vibration generation suppressing effect and the deformation preventing effect are further improved.

In the invention of claim 1, the convex portion may be provided along the end of the reinforcing plate (invention of claim 2), and in this way, the pressing range of the reinforcing plate against the bracket is further widened. Further, the vibration generation suppressing effect and the deformation preventing effect are further improved.
Further, in the invention according to claim 1 or 2, the bracket is a lever body formed through a bracket body portion in which the hole portion is formed, and a spring portion and a hinge portion that are elastically deformable at a lower portion of the bracket body portion. It is good also as a structure which comprises a part integrally and the said reinforcement board was attached to the said bracket main-body part (invention of Claim 3). If it does in this way, the bracket main-body part which requires rigidity can be favorably reinforced while permitting the elastic deformation of the spring part and the hinge part of the bracket.

In order to achieve the above-mentioned object, the invention of claim 4 includes a stay attached to the vehicle body, a bracket made of a synthetic resin attached to the tip of the stay for attaching the mirror housing so that the angle can be changed, A reinforcing plate attached to the bracket, and the reinforcing plate is formed in such a manner that the bracket is clamped from both the front and back surfaces, and the reinforcing plate has a screw insertion hole, and the bracket has a hole. The stay has a rotation holding member having a female screw portion formed at a tip thereof, and the head screw through the hole portion and the screw insertion hole portion is connected to the female screw portion of the rotation holding member of the stay. The reinforcing plate is attached to the bracket by being screwed into the bracket .
According to the invention of claim 4 , since the bracket is clamped from the front and back surfaces by the reinforcing plate, the rigidity of the bracket can be increased and vibration can be suppressed, and deformation of the bracket can be effectively prevented, In general, the antiglare mirror can be attached in a proper posture without vibration.

In this case, in the invention of claim 4 , the bracket is formed by a bracket body part in which the hole is formed, and a spring part and a hinge part that are elastically deformable at a lower part of the bracket body part. And the reinforcing plate may be configured to clamp the bracket main body portion and the spring portion (invention of claim 5 ). If it does in this way, while being able to reinforce the bracket main-body part which requires rigidity satisfactorily, the deformation | transformation to the front-back direction of the said spring part can also be prevented, without impairing the spring property of a spring part.

Further, in the invention according to any one of claims 1 to 5 , the mirror housing may be provided with parts other than the anti-glare mirror (invention of claim 6 ). Recently, a configuration in which other parts are built in the anti-glare mirror has been provided. In this case, there is a concern about an increase in vibration due to an increase in the weight of the anti-glare mirror. However, according to the sixth aspect , the reinforcing effect by the reinforcing plate is high, and even if the anti-glare mirror increases in weight, it is possible to suppress the occurrence of vibration and to prevent the bracket from being deformed.

In the invention of claim 6 , the mirror housing may be provided with a balance weight together with the components (invention of claim 7 ). According to the seventh aspect of the present invention, the weight unbalance applied to the bracket can be eliminated by the balance weight, but the weight further increases. Also in this case, the reinforcing effect by the reinforcing plate is high, and even if the anti-glare mirror increases in weight, vibration generation can be suppressed and deformation of the bracket can be prevented.

In the invention of claim 6 or 7 , the component may be a component related to an ETC on-board unit (invention of claim 8 ). Recently, a configuration in which an ETC on-vehicle device is incorporated in an anti-glare mirror has been provided. According to the invention of claim 8 , even with this type of anti-glare mirror, vibration generation is suppressed and deformation of the bracket is prevented. It is possible to reduce the influence of vibration on the ETC vehicle-mounted device.

A first embodiment of the present invention will be described below with reference to FIGS. FIG. 3 shows an antiglare mirror attaching device 2 to which the antiglare mirror 1 is attached. The attachment device 2 includes a stay 3, a bracket 4, and a reinforcing plate 5.
The stay 3 has a configuration in which a mounting member 7 for a vehicle body is rotatably provided at one end portion of a cylindrical stay main body 6 and a rotation holding member 8 is rotatably provided at the other end portion. The vehicle body attachment member 7 is attached to a vehicle body such as a front window glass. The bracket 4 is attached to the rotation holding member 8 by molding.

  The vehicle body mounting member 7 includes a sphere portion 7a, and the rotation holding member 8 also includes a sphere portion 8a. These sphere portions 7a and 8a are disposed in both ends of the stay main body 6, and include a spring 9 and a contact. When the plates 10 and 11 are pressed against the inner surface of the circular arc at both ends of the stay main body 6, the rotation angle is maintained. The rotation holding member 8 is formed with a female screw portion 8b.

  The bracket 4 formed by resin molding on the rotation holding member 8 is made of synthetic resin (for example, polypropylene), and as shown in FIGS. 5 and 6, the bracket body portion whose front surface is formed in a substantially flat surface. 12, a spring part 13 capable of elastic deformation in the vertical direction, a hinge part 14, a lower fitting shaft part 15, and a lever part 16 are integrally provided at the lower part of the bracket body part 12. Yes. An upper fitting shaft portion 12 a is formed on the upper portion of the bracket body portion 12. The spring portion 13 has a flat annular shape and has substantially the same thickness as the bracket main body portion 12. In addition, a hole 12 b is formed in a substantially central portion of the bracket body 12 corresponding to the female screw portion 8 b of the rotation holding member 8.

  The reinforcing plate 5 is formed in a substantially rectangular shape from, for example, a metal plate having a higher synthesis than the bracket 4, and a screw insertion hole portion 5 a is formed as a mounting portion at a slightly upper portion of the central portion of the reinforcing plate 5. ing. Further, convex portions (projecting toward the bracket 4) 5b and 5c are formed at the left and right end portions of the reinforcing plate 5, and a convex portion 5d is also formed at the lower end portion. . These convex parts 5b-5d are each formed in the form which follows an edge part. The protruding length A (see FIG. 6) of the convex portions 5b to 5d is set to a size within a range in which the reinforcing plate 5 does not cause plastic deformation at the time of attachment described later.

  The reinforcing plate 5 is attached to the bracket 4 by a headed screw 17 as an attachment member. In this case, the head screw 17 is screwed into the female screw portion 8 b of the rotation holding member 8 through the screw insertion hole portion 5 a of the reinforcing plate 5 and the hole portion 12 b of the bracket main body portion 12. In this case, it is preferable to screw in the periphery of the screw insertion hole 5a of the reinforcing plate 5 until it comes into pressure contact with the bracket body 12. As a result, the reinforcing plate 5 is elastically deformed in the screwing direction, and as a result, the reinforcing plate 5 is pressed against the left and right end portions and the lower end portion of the front surface portion of the bracket body portion 12 by the convex portions 5b to 5d. (See FIGS. 1, 2, and 7).

  The anti-glare mirror 1 has a mirror housing 18, and an upper fitting recess 18a and a lower fitting recess 18b are formed in the mirror housing 18, as shown in FIGS. Yes. The upper housing recess 18a and the lower housing recess 18b are engaged with the upper housing shaft 12a and the lower housing shaft 15, so that the mirror housing 18 is attached to the bracket 4 (FIG. 8).

  Further, as shown in FIG. 9, a circuit board 19 for an ETC vehicle-mounted device as a component other than the antiglare mirror is attached to the mirror housing 18 at a slightly right position. A balance weight 20 for balancing the weight is attached to the left side position. An anti-glare mirror body 21 is attached to the front surface of the mirror housing 18 as shown in FIGS.

  FIG. 1 shows a state in which the anti-glare mirror 1 is at a normal reflection angle α position. When the lever portion 16 is rotated in the arrow B direction from this state, the lower fitting shaft portion 15 causes the hinge portion 14 to move. It rotates while pushing up against the spring force of the spring part 13. In this case, since the bracket main body portion 12 does not move, the lower fitting shaft portion 15 relatively moves rearward with the hinge portion 14 as a fulcrum, and the lower portion of the mirror housing 18 similarly moves rearward. Thereby, as shown in FIG. 2, the mirror housing 18 tilts, and the anti-glare mirror body 21 is at the anti-glare reflection angle β position.

  According to such a present Example, the part between the convex parts 5b and 5c of the said both sides of the said reinforcement board 5 is the form by which the convex parts 5b and 5c of the both sides of the said reinforcement board 5 are pressed by the said bracket 4. FIG. Is attached to the bracket 4 so that the projections 5b and 5c at both ends of the reinforcing plate 5 are provided on the bracket 4 even if the front surface (the mounting surface of the reinforcing plate 5) of the bracket 4 is somewhat flat. Both sides are strongly pressed, and the reaction force of the pressing force acts on the portion between the convex portions 5b and 5c (screw insertion hole portion 5a portion) on both sides. As a result, the reinforcing plate for the bracket 4 The reinforcing force (pressing force) of 5 extends over almost the entire area of the bracket 4, and the rigidity of the bracket 4 can be increased to suppress the occurrence of vibrations, and the deformation of the bracket 4 can be effectively prevented. The mirror 1 can be attached to and properly posture state without oscillation.

In particular, according to the present embodiment, since 5d is formed at the lower end of the reinforcing plate 5 in addition to the convex portions 5b and 5c, the rigidity of the bracket 4 can be further increased.
Moreover, according to the present Example, since the said convex part 5b, 5c, 5d was set as the structure provided along the right-and-left end part and lower end part of the said reinforcement board 5, the pressing range of the reinforcement board 5 with respect to the bracket 4 is further. As a result, the vibration generation suppressing effect and the deformation preventing effect are further improved.

  Further, the bracket 4 is configured integrally with a bracket main body portion 12 and a lever portion 16 formed via a spring portion 13 and a hinge portion 14 that are elastically deformable at a lower portion of the bracket main body portion 12. Since the reinforcing plate 5 is attached to the bracket body 12, the bracket body 12, which requires rigidity, can be favorably reinforced while allowing the spring portion 13 and the hinge portion 14 of the bracket 4 to be elastically deformed. .

  In addition, according to the present embodiment, the reinforcing plate 5 has the screw insertion hole 15a in the portion located between the convex portions 5b and 5c on both sides, and the head that has passed through the screw insertion hole 15a. Since the reinforcing plate 5 is attached to the bracket 4 by screwing the attached screw 17 into the bracket 4, the convex portion 5 b can be obtained by simple assembly such as attaching the reinforcing plate 5 to the bracket 4 with the head screw 17. The strong pressing action to the bracket 4 by 5c, 5d can be obtained, and the vibration generation suppressing effect and the deformation preventing effect are further improved.

  10 to 12 show a second embodiment of the present invention. In this embodiment, the configuration of the reinforcing plate 31 is different from that of the first embodiment. That is, the reinforcing plate 31 includes a front plate portion 31a, left and right side plate portions 31b and 31c, a right rear plate portion 31d, and a left rear plate portion 31e. Is formed in such a manner that it is clamped from both front and rear sides.

The reinforcing plate 31 is fitted from above to clamp the bracket main body 12 and the spring portion 13 of the bracket 4 from the front and rear, and is screwed to the bracket 4 by a head screw 17.
According to the second embodiment, the bracket 4 is clamped from both the front and rear sides by the reinforcing plate 31, so that the rigidity of the bracket 4 can be increased and vibrations can be suppressed, and deformation of the bracket is also effective. In general, the anti-glare mirror can be attached in a proper posture without vibration.

In addition, according to the second embodiment, the reinforcing plate 5 is configured to sandwich the bracket main body 12 and the spring 13 so that the bracket main body 12 requiring rigidity can be favorably reinforced. At the same time, deformation of the spring portion 13 in the front-rear direction can be prevented without impairing the spring property (spring property in the vertical direction) of the spring portion 13.
The present invention is not limited to the above-described embodiments. For example, the convex portions may be at least at the end portions on both sides of the reinforcing plate. Further, the structure of the stay 3 is not limited to the structure of the above embodiment. Further, the components incorporated in the anti-glare mirror 1 may be other than the ETC circuit board. Moreover, you may provide a convex part in the perimeter end of a reinforcement board.
