DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a turnover type door mirror in which the attitude of the mirror is manually adjusted from inside a vehicle.

(Prior art) Conventionally, this type of device was
-134346 is publicly known. In this invention, when the knob 51 of the operating lever 50 is operated in the left-right direction as shown in FIGS.
The rotation of the shaft 55 is transmitted to the arm 57 via the horizontal rod 56 fitted to the upper end of the shaft 55, and the rotation of the shaft 55 is transmitted to the arm 57 through the meshing motion of the gear 54. The mirror 59 is moved by the left-right movement, and the inclination of the mirror 59 in the left-right direction (α direction) is adjusted. When the operating lever 50 is operated in the vertical direction, the vertical movement of the operating lever 5° is caused by the engagement of the operating lever tip 60 and the groove 61 with the fulcrum 52 as the fulcrum, and the shaft 55 and the horizontal rod fitted onto the shaft 55. The mirror 59 is moved by the vertical movement of the arm 57 centered on the pivot 58 which is transmitted as the vertical movement of the horizontal rod 56, and the inclination of the mirror 59 in the longitudinal direction (β direction) is adjusted. It is.

(Problem to be Solved by the Invention) However, in the door mirror having the above structure, the mirror is tilted in the longitudinal direction by operating the operating lever in the vertical direction, so the purpose of adjusting the mirror in the longitudinal direction is The operating direction of the operating lever and the operating direction of the operating lever do not match, making it difficult to adjust the forward and backward tilting of the mirror. Since the lever is slanted, the operating space in the vertical direction of the operating lever is limited, and there is a problem in that it is difficult to operate the operating lever. Furthermore, the up and down movement of the shaft that tilts the mirror forward and backward is such that the up and down movement of the operating lever using the fulcrum method as a fulcrum is directly transmitted to the lower end of the shaft, so the shaft is twisted during up and down operation.
This has the disadvantage that smooth vertical movement of the shaft is hindered.

(Means for Solving the Problems) The present invention aims to solve the above-mentioned problems. and a fulcrum disposed inside the base that supports it so as to be rotatable left and right, a rod that is rotatable and movable up and down and connected to the fulcrum via a swinging member, and a rod that is connected to the other end of the rod. and a shaft inserted into the cylinder shaft so as to be rotatable and vertically movable; and a horizontal rod having one end attached to the upper end of the shaft and the other end extending in the longitudinal direction within a plane parallel to the mirror visor. , a conversion arm is provided between the other end of the horizontal rod and the mirror holder in order to convert the vertical movement and rotation of the shaft into tilting of the mirror back and forth and left and right; The mirror can be tilted left and right and back and forth in response to left-right swinging and left-right rotation.

Through a plurality of ball clutches that are held in a compressed state between the stop plate 8 that is locked on the upper edge and the seat surface of the receiver tube 10, and are arranged between the lower surface of the receiver tube lO and the seat surface of the shaft tube 9. The mirror visor 3 is elastically supported on the base 5.

As shown in FIGS. 1, 2, 3, and 4, the operating lever 12 has one end provided with a knob 11 protruding into the vehicle interior, and the other end is provided with a fulcrum 13, and is attached to a stay 6. The fulcrum 13 held in the fulcrum holder 14 provided within
It is rotatably supported in the left-right direction (directions A and B in FIG. 3) and in the left-right rotation direction (directions C and D in FIG. 3) about the fulcrum.

A connecting piece 15 and a boss 17 protrude from both sides of the fulcrum 13, and a connecting pin 16 is inserted into a connecting hole 15a provided at the end of the connecting piece 15 to connect the swinging member 18 and the fulcrum 13. It is connected. The swinging member 18 is formed into a substantially U-shape, and the connecting piece 15 and the boss 17 are swingably accommodated in grooves 19 provided at both ends. The swinging member 18 can be moved in the left-right direction for directional operations, and in the up-down direction for clockwise and counterclockwise operations. The swinging member 18
At the bottom of the fulcrum method 13, there is an L-shaped rod 20 on the spherical axis of the fulcrum method 13.
are connected to each other, are supported by a guide 21 that is slidably fixed to the mounting stay 6, and are linked to the movement of the swinging member 18, and extend horizontally from the lower end of the vertical rod portion 20a of the rod 20. A locking piece 22 with a long groove 23 is provided at the end of the horizontal rod portion 20b, and the rod 20 is inserted from the lower end of the shaft 25 inserted into the shaft cylinder 9 toward the axis of the shaft 25. The pin 2 is inserted through the horizontally extending lower arm 26 and the long groove 23 of the locking piece 22.
4, and transmits the movement of the rod 20 in response to the operation of the operating lever 12 to the shaft 25. shaft 25
A horizontal rod 27 extending in a horizontal plane along the longitudinal direction of the mirror visor 3 is fixed to the upper end of the mirror visor 3, and the tip of the horizontal rod 27 is unevenly located near the mounting stay 6 on the back side of the mirror holder 2 so as to be connected to the vertical direction. The conversion arm 28 is connected to a connecting rod 28c of a conversion arm 28, which is equipped with a pair of operating rods 28a that engage in a pair of guide grooves 29a formed in a cam plate 29 vertically installed in parallel with the axis Y. , a base rod 28b, a pair of operating rods 28a protruding from both sides of the base rod 28b, and a connecting rod 28 that is perpendicular to the operating rod 28a and protruding from the base rod 28b.
The connecting rod 28c is connected to the horizontal rod 27 fixed to the upper end of the shaft 25 to transmit the vertical movement or rotational movement of the shaft 25 to the conversion arm 28. A pair of guide grooves 29a provided in the cam plate 29 vertically disposed on the back surface of the mirror holder 2 are formed as inclined grooves in opposite directions with respect to the horizontal axis X (see FIG. 3).

(Fig. 5), when the shaft 25 moves upward, the conversion arm 28 also moves upward via the horizontal rod 27, and the operating rod 28a pushes up the inclined wall of the guide groove 29a, so that the mirror 1 supported by the spherical pivot 4 moves forward. lean in a direction. That is, the upper operating rod pushes up the wall of the upper inclined groove that is inclined in the direction away from the mirror 1, and the lower operating rod pushes up the wall of the lower inclined groove that is inclined in the direction closer to the mirror 1, so that the mirror 1
tilts forward using the ball pivot 4 as a fulcrum. The rearward tilting of the mirror 1 is performed by the above-mentioned reverse operation when the conversion arm 28 moves downward. Further, the mirror 1 is tilted in the left-right direction by the rotational movement of the shaft 25.

That is, when the shaft 25 rotates clockwise (the third
6), the operating rod 28a of the conversion arm 28 to which the horizontal rod 27 rotates around the shaft 25 and connects the cam plate 29 of the mirror holder 2 (the inclined guide groove 9a)
6, the operating rod 28a acts to push out the mirror 1 that is supported by the spherical pivot 4, and moves the mirror 1 around the spherical pivot 4 to the lower side in FIG. In the figure, the mirror l is tilted counterclockwise. Further, when the shaft 25 rotates counterclockwise, the conversion arm 28 operates in the opposite direction as described above, thereby tilting the mirror l in the opposite direction.

Next, the operation of this embodiment will be explained.

First, when the operating lever 12 is operated in the right direction (in the direction of the arrow in FIG. 3), the swinging member 1
8 and the rod 20 rotate, and the locking piece 22 at the tip of the rod swings to the left (in the direction of arrow AI).

This swing is caused by pin 24. The rotational movement is transmitted to the shaft 25 via the lower arm 26, and the horizontal rod 27 fixed to the upper end of the shaft 25 is swung to the right (in the direction of arrow A11), thereby causing the mirror 1 to move as shown in FIG. to the right (A
[[Move in [direction]. That is, the operating lever 12
This means that the movement of the mirror 1 matches the swinging direction of the mirror 1.

Similarly, when the operating lever 12 is operated to the left (in the direction of arrow B in FIG. 3), the horizontal rod 27 is moved to the left (arrow Bn
direction) to move the mirror l to the left (BIIr direction). Next, when the operating lever 12 is rotated to the right around the fulcrum 13 via the knob 11 (in the direction of arrow C in FIG. 3), the connecting piece 1 protrudes to one side of the fulcrum 13.
A swinging member 1 rotatably supported by a pin 16 at
8 also rotates in the same direction around the fulcrum 13,
At this time, since the vertical rod 20a of the L-shaped rod 20 connected to the swinging member 18 is slidably supported only in the vertical direction by the guide 21 fixed to the mounting stay 6, the rod 20 is pulled vertically upward. It will be done.

Therefore, the bent horizontal rond portion 2 of the loft 20
The lower arm 26 connected to the rod 20 is moved upward, and the shaft 25 is thus moved upward parallel to the rod 20.
The transverse rod 27 fixed to the upper end also moves upward, and this upward movement is transmitted to the cam plate 29 via the actuating rod 28a of the translation arm 28, as described above, where it is moved as shown in FIG. The movement of the cam plate 29 and the mirror 1 is converted into a movement in the forward tilting direction.

Similarly, the operating lever 12 is moved to the fulcrum method 1 via the knob 11.
When the mirror 1 is rotated to the left about 3 (in the direction of the arrow in FIG. 3), the movement of the mirror 1 is converted into a movement in the backward tilting direction. In this way, the movement of the mirror 1 adapts to the left-right swinging operation and left-right rotation operation of the operating lever 12.

(Effect of the invention) Since the present invention is configured as described above,
The left/right tilting and front/back tilting of the mirror corresponds to the left/right swinging and left/right rotation operations of the operating lever, and the operating lever operation and the movement of the mirror tactilely match, making it possible to adjust the mirror without any hassle. In addition, since the vertical movement of the operating lever is eliminated, the operation of the operating lever is no longer restricted by the narrowness of the operating space, and the mirror adjustment can be smoothly performed, which is an excellent effect.

Furthermore, since the vertical movement is transmitted from the operating lever to the shaft in parallel to the axis of the shaft, there is an excellent effect that the shaft is not twisted during vertical movement, and the vertical movement of the shaft is performed smoothly.
