Description

  The present invention relates to a connecting device for a side mirror with a screw-in type stay that can connect a vehicle and a side mirror so as to be rotatable and can easily return to a predetermined position and be fixed even when the position of the side mirror is shifted. About.

  Passenger vehicles are equipped with mirrors as necessary parts for safety confirmation, such as grasping surrounding information. A mirror in a passenger vehicle including a steering device of a handlebar type such as a motorcycle is generally attached to the vehicle via a bent bar-like stay.

  When mounting a motorcycle mirror, it is necessary to satisfy the safety standards of the transport vehicle, and one of them is “there is no risk of injury to pedestrians”. Therefore, according to the technique of Non-Patent Document 1, the stay is attached to the vehicle by combining a male screw formed at the tip of the stay with a reverse screw adapter. One of the screws is rotated in the loosening direction by the contact, so that the impact is reduced. According to such a technique, there is a possibility that the impact on the pedestrian and the driver can be mitigated even when the mirror of the motorcycle comes into contact with a pedestrian or the like unintentionally.

  However, since the degree of buffering varies greatly depending on the tightening force of the operator when mounting, the safety is uncertain.

  Also, when the mirror position or angle is shifted, it is necessary to adjust the mirror position and angle to the original position according to the user's physique and how to ride. This adjustment work is very difficult for users who do not need tools in daily life, and had to go to a specialist store.

  In addition, such mirror misalignment occurs relatively frequently, but there are no specialty stores nearby, or the user neglects to make adjustments, and the motorcycle is left as it is and the mirror remains loose. Some people did it and it was very dangerous.

  Furthermore, for example, when parking in narrow places where vehicles such as bicycles and motorcycles are randomly parked, or when passing through similar narrow places, as described above, the position of the side mirror is changed. Since it cannot be changed easily, the width of the road must be widened by the overhanging side mirror, and the driver needs to be careful not to catch the side mirror, which is cumbersome and difficult to pass. It was.

When the rotary attachment 12 receives a force in a direction away from the fixed attachment 13, the head 161 of the assembly bolt 16 hits the stepped portion 1231 of the insertion hole 123 and moves in a direction away from the fixed attachment 13. The rotation-side attachment 12 is prevented from being detached from the fixed-side attachment 13 and falling off.
(Engagement part 17)

  In the first embodiment, the engaging portion 17 maintains the fixed state of the rotation-side attachment 12 until the external force applied to the rotation-side attachment 12 exceeds a predetermined threshold, and when the external force exceeds the predetermined threshold, the rotation-side attachment 12 It is a member for rotating. The engagement portion 17 is fixed to the assembly bolt 16 that restricts the movement of the rotation-side attachment 12 in the rotation axis direction and the rotation radius direction, the first engagement surface 125 and the spherical recess 122 of the rotation-side attachment 12, A steel ball 15 that is elastically biased by the second engagement surface 133 and the first hole 132 of the side attachment 13 and the spring 14 inserted into the first hole 132 and constantly presses the rotation-side attachment 12; It consists of

  The spring 14 is formed between the spherical recess 122 of the rotation side attachment 12 and the first hole 132 of the fixed side attachment 13 so as to urge the first engagement surface 125 and the second engagement surface 133 in the opposite direction. The first engagement surface 125 of the rotary attachment 12 or the spherical recess 122 is fixed to the fixed attachment via the steel ball 15 interposed in a contracted state between the springs 14 and placed on the spherical recess 122 side of the spring 14. Always pressing in the direction away from 13.

  The rotation-side attachment 12 is assembled with the urging force by the spring 14 via the rigid sphere 15 in the rotation axis direction when the steel ball 15 is fitted by the spherical recess 122 under the pressure of the spring 14. Since the drag force from the head 161 of the bolt 16 is balanced and the drag force from the rigid sphere 15 fitted in the ball-shaped recess 122 is balanced against the external force in the rotation direction of the rotation-side attachment 12, a predetermined value is obtained. Unless an external force exceeding the threshold value is applied, the ball stays stably at the position of the spherical recess 122. On the other hand, when the steel ball 15 is in a position in contact with the first engagement surface 125 under the pressure of the spring 14, the rotation side attachment 12 is biased by the spring 14 via the rigid ball 15 in the rotation axis direction. And the drag from the head 161 of the assembly bolt 16 are balanced, and in the rotational direction of the rotation side attachment 12, the steel ball 15 and the first engagement surface 125 are in contact with each other at only one point. Since the drag force is only the frictional force between the first engagement surface 125 and the second engagement surface 133, it can be easily rotated.

  Thereby, the rotation of the rotation attachment 12 is prevented unless the external force exceeding a predetermined threshold is applied to the rotation attachment 12 in the rotation direction. In other words, the rotation-side attachment 12 does not rotate until the external force exceeds the predetermined threshold value, and rotates when an external force exceeding the predetermined threshold value is applied in the rotation direction, so that the steel ball 15 is fitted by the spherical recess 122. Even in the next stable position, rotation is maintained if an external force exceeding a predetermined threshold is applied. In this first embodiment, the rotation-side attachment 12 has a stable position every time it is rotated by 90 °. Therefore, if an external force exceeding a predetermined threshold is not applied at any of the stable positions, the rotation-side attachment 12 is at the stable position. Fixed.

  This threshold value is defined as the minimum value of the external force required to rotate the rotation-side attachment 12 (the same applies to other embodiments). A fixed value is not necessarily meant because it can be changed depending on whether an external force is applied to the steel ball 15 or whether the steel ball 15 and the spherical recess 122 are engaged with each other.

  On the other hand, if this threshold is too large, the rotation-side attachment 12 will not rotate even if an impact is applied to the side mirror MI, and the side mirror MI will be damaged, or the driver's steering wheel operation will be wrong. If it is too small, the side mirror MI cannot be stably fixed. Therefore, the threshold value needs to be a value that does not rotate with a small external force but can rotate with respect to a certain large external force. For this reason, the engagement portion 17 is devised so that the external force applied to the rotation-side attachment 12 is directed in the extending direction of the spring 14 as a component force.

  In this first embodiment, until the external force exceeds a predetermined threshold, the notched recess 122 is recessed in such a way that a part, not all of the steel ball 15, is fitted. Since the spherical crown-shaped recess of the spherical recess 122 becomes a resistance, the rotation side attachment 12 is fixed at a fixed position. On the other hand, when the external force exceeds a predetermined threshold value, the steel ball 15 is released from the spherical crown-shaped recess of the spherical recess 122, and the rotation-side attachment 12 rotates in the external force direction. When the steel ball 15 is released from the spherical crown-shaped recess of the spherical recess 122, an external force applied to the rotation-side attachment 12 due to the engagement between the spherical body of the steel ball 15 and the spherical recess of the spherical recess 122 is obtained. A component force based on the stretching direction is generated. This component force acts on the steel ball 15 and pushes the steel ball 15 into the first hole 132 while contracting the spring 14.

In the first embodiment, a case where a spherical recess 122 is provided in the rotary attachment 12 and a first hole 132 is provided in the fixed attachment 13 is described. The hole 132 may be provided with a spherical recess 122 in the fixed attachment 13.

(Engagement part 26)

  In the second embodiment, the engaging portion 26 maintains the fixed state of the rotation side attachment 22 until the external force applied to the rotation side attachment 22 exceeds a predetermined threshold value. It is a member for rotating the attachment 22. The engaging portion 26 is elastically biased by the regular pyramid recess 232 of the fixed side attachment 23 and the spring 24 inserted into the second hole 223, and always presses the fixed side attachment 23. 22 regular pyramid convex portions 222.

  When the regular pyramid convex portion side 2222 and the regular pyramid concave portion first side 2322 are in contact with each other under the pressure of the spring 24, the regular pyramid convex portion 222 is fitted by the regular pyramid concave portion 232. The As a result, the rotation-side attachment 22 balances the urging force of the spring 24 with the drag from the regular pyramid recess 232 in the rotation axis direction, and the rotation direction of the rotation-side attachment 22 is positive with respect to the external force. Since the drag force from the pyramid recess 232 is balanced, the external pyramid recess 232 stays stably unless an external force exceeding a predetermined threshold is applied. On the other hand, the rotation-side attachment 22 rotates when the regular pyramid convex part side 2222 of the regular pyramidal convex part 222 is in a position in contact with the regular pyramid concave second side 2323 under the pressure of the spring 24. In the axial direction, the urging force of the spring 24 and the drag force from the regular pyramid recess 232 are balanced, and in the rotational direction of the rotation side attachment 22, the contact between the regular pyramid projection 222 and the regular pyramid recess 232. The surface is only a point where the regular pyramid convex part side 2222 of the regular pyramidal convex part 222 intersects the regular pyramid concave part second side 2323, and the area that generates a frictional force that resists external force is extremely small. Therefore, it can be easily rotated.

  As a result, the rotation-side attachment 22 does not rotate until the external force exceeds a predetermined threshold value, but rotates when an external force exceeding the predetermined threshold value is applied, and the regular pyramid convex portion 222 is fitted by the regular pyramid concave portion 232. Even in the next stable position, rotation is maintained if an external force exceeding a predetermined threshold is applied. In the second embodiment, since the rotation side attachment 22 has the same number of stable positions as the number of the regular pyramidal convex side surfaces 2221 of the regular pyramid, the external force has a predetermined threshold value at any of the stable positions. Until it exceeds, it is fixed in its stable position. Since the threshold is the same as that in the first embodiment, the description thereof is omitted.

  In this second embodiment, until the external force exceeds a predetermined threshold, the regular pyramid recess 232 fits the regular pyramid convex part 222, and the regular pyramid convex part side surface 2221 and the regular pyramid concave part side surface 2321 Therefore, the rotation side attachment 22 is fixed at a fixed position. On the other hand, when the external force exceeds a predetermined threshold value, the regular pyramidal protrusion 222 is removed from the state of being fitted by the regular pyramidal recess 232, and the rotation side attachment 22 rotates in the direction of the external force. When the regular pyramid convex part 222 is removed from the fitted state, the spring 24 based on the external force applied to the rotation side attachment 22 due to the engagement between the regular pyramidal convex part 222 and the regular pyramid concave part 232 is used. A component force in the stretching direction is generated. This component force acts on the rotation-side attachment 22 and causes the regular pyramid convex side surface 2221 and the regular pyramidal concave side surface 2321 to be in a non-contact state while contracting the spring 24.

In addition, in 2nd Example, although the case where the regular pyramid convex part 222 was provided in the rotation side attachment 22 was described, you may be provided in the fixed side attachment 23, In this case, a regular pyramid The body recess 232 is provided in the rotation side attachment 22.
