Abstract

PURPOSE:To remove readjustment of mirror angle by so mounting a control lever as to be possible to rotate in a base and providing a shaft inside the bearing of the base and connecting a transverse lever mounted on the shaft through a clutch with a mirror holder. CONSTITUTION:A clutch B is laid at a contact face between a shaft 11 and a transverse lever 25 and a locking sphere 28 is pressed by a spring and engaged with the recessed portion of the shaft 11. And when external force is applied and a mirror body 4 is brought, the sphere 28 is easily released resisting the spring 30 force. On the other hand, when the mirror body 4 is returned from the bright down condition to a normal use position, the locking sphere 28 engages with the recessed portion of the shaft 11 and the shaft 11 and the transverse lever are connected again at a a proper mounting angle. In this case, the transverse lever 25 for adjusting a mirror 8 angle and the arm base part 31 are kept in the previous position before the bringing down of the body 4, therefore there is no need to readjust the mirror 8 angle over again.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a turnover type device in which the angle of a mirror provided in a mirror body can be remotely adjusted in the forward direction by operating a lever extending into the vehicle interior. This relates to the inside and outside rearview mirrors.

[Prior Art] Automobile door mirrors in which the mirror body tilts when a large external force is applied and return to its original position when the external force is removed are widely known as separate attack avoidance type or tilting type mirrors. However, recently, due to the need to narrow the parking width when entering a parking lot or shipping by ship, we have developed a foldable mirror that allows the mirror body to be tilted almost at right angles to the rear of the vehicle from its normal use position and maintained in that position. is widely used. Each mirror is provided with a mirror angle adjustment device that is tiltably supported within the mirror body, and can be remotely operated from inside the vehicle.

[Problems to be Solved by the Invention] There are two ways to remotely adjust the angle of the chain: electrically and manually. Electrical remote control devices require little control and are expensive.

In addition, in the case of a manual device, it is relatively inexpensive because it uses a link gate structure, but it is quite difficult to provide a link mechanism that will not be damaged even by large movements when the mirror body is folded down. Even if this difficulty is solved, the angle adjustment gate mechanism of the mirror will also be moved when the mirror body is folded down, so if the mirror body is returned to its normal position after being tilted backwards or forwards, the angle of the mirror will be readjusted each time. There was a problem that needed to be adjusted.

The present invention provides a turnover type remote control rearview mirror in which a remote control device 1 is installed, which can tilt the mirror in the same direction (forward direction) as the operating direction of the operating lever protruding into the vehicle interior, and which To provide a door rearview mirror that does not damage the angle adjustment mechanism of the mirror when folded down, and does not require readjusting the angle of the mirror when the body is returned to its normal position from the folded position. It is said that

[Means for Solving the Problems] In order to achieve the above object, the present invention improves the angle adjustment mechanism after the operation lever. In other words, a mirror body is attached to a cylindrical bearing mounted on a base so that it can be tilted forward and backward, and the angle of the mirror supported by a central pivot inside the mirror body can be adjusted using an operating lever protruding from the base. In a rearview mirror: A bell crank-shaped operation lever connection part is rotatably installed in the base, in which a lever protruding inward from the base and a vertical lever are connected at right angles; the lower end of the vertical lever and The upper end of a connecting rod that is swingably mounted in the base is connected through a bending joint so that it can be bent and rotated; the lower end of this connecting rod is inserted into the bending part and the cylindrical bearing so that it can be raised and lowered and rotated. The bent portion of the lower end of the shaft is connected via an operating rod that is swingably mounted in the base.The mirror holder is connected to the horizontal rod that is swingably mounted to the upper end of the shaft via a clutch means. It is characterized by being connected.

[Function] When the horizontal lever attached to the upper part of the shaft is rotated in the same direction as the operating lever when the shaft is moved left and right by the operating lever, the mirror holder connected to the horizontal lever in a link-like manner is connected to the operating lever. is rotated in the opposite direction. This allows you to adjust the left and right angle of view of the mirror. That is, when the control lever is pulled toward the user, the mirror tilts inward, and when the control lever is pushed toward the front of the vehicle, the mirror tilts outward. On the other hand, is it 1 by the control lever?
When the foot is raised and lowered to raise and lower the horizontal rod in the opposite direction to the operating lever, the mirror holder is rotated in the same direction as the operating lever. This adjusts the vertical deflection angle of the mirror. If you pull up the operating lever, the mirror will tilt upward, and if you press down on the operating lever, the mirror will tilt downward.

Further, when the mirror body is artificially tilted to the inside of the outermost line of the vehicle, the clutch means provided at the connection part between the shaft and the side rod is activated to release the connection between the shaft and the side +1,
The mirror is knocked down while maintaining its adjusted deflection angle. Even when the mirror body in the folded state is returned to its normal position, the connection between the shaft and the horizontal rod remains disconnected, so the mirror body returns to its normal position while maintaining the initial angle of view of the mirror.

``Example'' Next, the present invention will be described in detail based on the illustrated example.

is inserted so that it can rotate freely in the same way as lifting and lowering. The shaft 11
A horizontal bent portion 11b is provided at the lower end of the holder, and a socket 11c is formed at the tip of the bent portion 11b.

The operating lever 9 is a protruding lever 9 that protrudes into the vehicle interior.
a, and a vertical lever 9b extending downward at right angles to the protruding lever 9a, forming a bell crank shape. Projecting lever 9
A knob 12 is attached to the outer end of a, and a rotation pivot 13 formed at one end is disposed within the base 2. This rotating pivot 13 serves as a connecting portion between the protruding lever 9a and the vertical lever 9b, and is rotatably supported by a spherical bearing 14 provided in the base 2 using the presser cover 2a. A bell crank-shaped connecting rod 18 is connected to the lower end of the vertical lever 9b via a bending joint. That is, the pivot 19 of the connecting rod 18 is fitted into a spherical bearing 20 mounted in the base 2 via a bracket 2b, and is freely supported. The refractive joint Δ is connected to the vertical lever 9b as shown in FIG.
The rotating pivot 16 provided at the lower end is fitted into the socket 18c provided at the upper end of the connecting rod 18, and the pin 17 protruding from the pivot 16 is inserted into the elongated hole 18d made in the wall of the socket 18c. As a result, the levers 9b, ! : The connecting rods 18 are rotated in a bent state using the respective support pivots 13 and 19 as rotation fulcrums. Further, a horizontally bent portion 18a is provided at the lower part of the pivot 19, and a pivot 18b is attached to the tip thereof.

The connecting rod pivot 18b is connected to an operating rod 23 provided at the bottom of the base 2. The operating rod 23 is the bracket 2
G, spherical bearing 22, and pivot 2). A socket 23 provided at the tip of the operating rod 23
The pivot 18b is rotatably fitted into the shaft 11, and the pivot 24a provided at the tip of the other operating rod 24 is rotatably fitted into the bent socket 11b of the shaft 11. The connecting rod 18 and the shaft 11 are connected.

By connecting the operating lever 9 and the shaft 11 in this way, when moving the knob 12 up and down, the lever 9
a is rotated in the vertical direction about the pivot 13, and as a result, the lever 9b and the connecting rod 18 are bent in the left-right direction in FIG. The shaft 11 is moved up and down in the opposite direction to the lever 9 via the actuating rods 23,24. On the other hand, when moving the knob 12 left and right, the lever 9a
is rotated once in the left-right direction about the pivot 13, which causes the connecting rod 18 to rotate via the lever 9b, the bent pivot 18b of the connecting rod 18 moves left and right, and the shaft 11 moves to the operating rod 23. .24 in the same direction as the lever 9a. In this case, since the operating lever 9 is rotated via the pivot 13, its operation is easily performed. Also, since the shaft 11 operated by this lever 9 is driven in a link-like manner via each pivot,
Its operation is carried out smoothly.

Further, a horizontal rod 25 is rotatably fitted to the upper part of the shaft 11, and as will be described later, the shaft 11 and the horizontal rod 25 are fitted so that the connection between the shaft 11 and the horizontal rod 25 can be temporarily released when the mirror is folded down. Clutch means B is attached to the joint between 11 and the binding hole 26 at the base of the horizontal rod. This clutch means B has a small-diameter horizontal hole 27 that communicates with the outer upward vertical hole 26 of the horizontal rod 25, and a locking member 28 is inserted into the horizontal hole 27 so that its inner surface is carved on the outer surface of the shaft 11. engage with the provided recess 29,
The outer surface is fixed to a leaf spring 30 provided at the outer end of the horizontal rod 25.

The pivot 1 at the tip of the arm 32 is formed with a socket 34 at the tip of the horizontal rod 25 and protrudes from the back side of the small mirror holder 7.
-33 is rotatably connected to tff1. Further, a protruding member 5a having a central pivot 6 is fixed to the mirror support 5, and a connecting rod 36 is pivotally attached using a pin 35. A pivot 37 is provided at the tip of the connecting rod 36, and is rotatably fitted into a socket 38 formed in the base 31 of the 7-arm 32.

Reference numeral 35 denotes a connecting rod, a part of which is pivotally attached to the mirror support 5, and a pivot 37 provided at the tip of an arm 36 is movably fitted into a socket 38 formed on one side of the operating body 31. There is.

The operation of the above embodiment will be explained with reference to FIGS. 5 and 6.

As shown in FIG. 4, a clutch means B is provided at the joint surface between the shaft 11 and the base of the horizontal rod 25, so that the mounting angle between the shaft 11 and the horizontal rod 25 is always maintained constant during normal use. This means that it has been done.

When the knob 12 protruding into the vehicle interior is moved left and right in this manner and the lever 9a is rotated, for example, clockwise (in the direction of the arrow in FIG. 2) via the pivot 13, the connecting rod 18 is rotated via the lever 9b. and the pivot 1 at the tip of the connecting rod 18
8b rotates clockwise as indicated by the arrow. As a result, the shaft 11 rotates via the operating rods 23 and 24 in the clockwise direction indicated by the arrow, that is, in the same direction as the knob 12, and the arm base 31 is pushed by the horizontal rod 25, which rotates together with the shaft 11. vL pulled and supported by central pivot 6
8 in a direction compatible with the operating direction of the knob 12,
The horizontal deflection angle is adjusted.

On the other hand, move the knob 12 up and down to move the lever 9a to the pivot 13.
When the lever 9b and the connecting rod 1 are rotated in the vertical direction through the
8 is bent in the left-right direction in FIG. 1 through the bending joint, and the pivot 18b at the tip of the connecting rod 18 moves downward by -F. As a result, the shaft 11 moves up and down in the opposite direction to the movement of the knob 12, and the arm base 31 is connected to the pivot 3 of the connecting rod 36 by the horizontal rod 25, which moves up and down together with the shaft 11.
7, the knob 120 is tilted in a direction that conforms to the direction of rotation, and the photographing angle in the -vertical direction is adjusted.

Here, since the lever 9 is rotated via the pivot 13, its operation is easily performed, and the shaft 11 operated by the lever 9 is driven in a link shape via each pivot, so that Its lifting, lowering, and rotation are performed smoothly. Therefore, the angle of the mirror can be adjusted accurately and easily. Note that when the knob 12 is operated diagonally upward or diagonally downward, the combined moving angle of the mirror 8 in the vertical and horizontal directions is adjusted.

By the way, when the vehicle is stored or transported, the mirror body 4
When the mirror body 4 is tilted backward or forward to a critical angle just before contacting the vehicle body, or when the mirror body 4 is suddenly rotated about the shaft 11 due to an unexpected impact, the joint between the shaft 11 and the horizontal rod 25 Although a large 1-lux is applied to the rearview mirror of the present invention, the following avoidance means operates to prevent the connection from breaking.

As mentioned above, the clutch means B is interposed at the joint surface between the upper part of the shaft 11 and the vertical hole 2G of the horizontal rod 25.
In normal use of the mirror, the outer surface of the locking sphere 28 is pushed inward by the temporary spring 30, and the inner surface is fitted into the four parts 29 of the shaft 11. In this state of use, when a strong external force is applied to the mirror body 4 and the body 4 falls, for example, 90 degrees toward the rear of the vehicle, the horizontal rod 25 rotates together with the mirror body 4, as shown by the chain line in FIG. However, at this time, the locking sphere 28 is easily l1i1iI152 from the four parts 29 against the pressing force of the leaf spring 30. Therefore, an excessive load is not applied to the coupling mechanism between the shaft 11 and the horizontal rod 25.

Also, when the mirror body 4 is returned from the folded state to the normal use position, the lever 1 -
The sphere 28 fits into the recess 29, and the synft 11 and the horizontal rod 25 are connected again at a proper mounting angle.

In this case, the horizontal rod 25 and arm (4) that adjust the angle of the mirror 8 are used.
Since the mirror body 4 is held at the 6z position before the mirror body 4 is tilted, there is no need to readjust the angle of the mirror 8 after the mirror returns.

[Effects of the invention] As described above, the rearview mirror of the present invention has rI
N By manually operating a lever extending into the interior, the angle of the chain can be remotely adjusted in the direction of operation and in the forward direction.
When added, the mirror body can be moved to the inside of the outermost line of the vehicle.

In particular, in the rearview mirror of the present invention, the operating lever is formed into a bell crank shape with a lever protruding into the interior of the vehicle from the pace and a lever extending downward into the base, and the connecting portion of both levers is rotatably supported within the base. The operating lever and the mirror tilting shaft are connected like a link through a pivot and a bending joint, so that the lever can be easily moved from side to side or up and down, and the shaft can be moved up and down or rotated smoothly. Since the mirror is configured so that the angle of the mirror can be adjusted easily and accurately, it is possible to adjust the angle of the mirror easily and accurately.

Further, in the rearview mirror of the present invention, the shaft for tilting the mirror and the horizontal rod connected to the upper part of the shaft are connected via a clutch means, and when the mirror body is tilted forward or backward, the clutch means is disengaged and the horizontal rod is connected to the shaft for tilting the mirror. Since it is constructed so that it can rotate around the shaft, there is no possibility that an excessive load will be applied to each joint when it is folded down, and therefore each joint will not be damaged. Also, on the same day, when the mirror body is folded down or returned to normal usage from the folded state, the relative angles of the joints do not change.
There is no need to readjust the tilt of the mirror when the mirror returns, and the mirror can be used as is.
