Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a manual adjustment device for a foldable mirror for manually adjusting the attitude of the mirror from inside a vehicle.

(Prior Art) Door mirrors for automobiles that have a structure in which the mirror visor tilts when a large external force is applied and return to the original position when the external force is removed are well known as so-called tilting mirrors. In addition, a mirror in which the tilt angle of the mirror visor is further increased to approximately 90 degrees from the normal position and can be maintained in that position is known as a so-called foldable mirror. All of the mirrors are equipped with a mechanism for adjusting the attitude of the mirror, which is tiltably supported within the mirror visor, and some mirrors allow the attitude of the mirror to be adjusted remotely from inside the vehicle. There are two types of remote adjustment devices: electrical ones and manual ones, but in the case of the above-mentioned foldable mirror, the tilt angle of the mirror visor is large, so the manually operated adjustment axis is attached to the mirror visor. It is difficult to install the device in a manner that does not impede movement, and an electrical remote control device has generally been used.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned problems, and aims to provide an extremely inexpensive manual adjustment device that can be applied to a folding mirror with a large tilt angle. .

(Means for Solving the Problems) That is, the manual adjustment device for a foldable mirror according to the present invention rotatably attaches a mirror visor, which supports a mirror holder in a tiltable manner, to a mirror stay provided on the outer surface of a vehicle. In the attached foldable mirror, an operating lever is provided that passes through the mirror stay from the inside of the vehicle to the mirror visor side and is supported by the mirror stay so as to be able to freely rotate around the axis and tilt the axis, and the operating lever and the mirror A connecting mechanism for removably connecting the holder is provided between the support part of the operating lever relative to the mirror stay and the rotating shaft of the mirror visor relative to the mirror stay, and the connecting mechanisms are opposed to each other so that at least one side is connected to the other side. It consists of a pair of coupling members installed on the operating lever and the mirror visor, respectively, so that the two are spring-biased and in contact with each other with a constant pressure. The coupling member is provided with two protrusions on the other hand, and an engagement recess that faces each of the protrusions and removably engages the protrusions on the other side of the coupling member, and the protrusion is engaged with the engagement recess. The mirror holder is freely displaced relative to the mirror visor by rotation or tilting of the operating lever, while the mirror visor is freely displaced relative to the mirror stay when the projection is disengaged from the engagement recess against spring pressure. It is characterized by the following.

(Function) According to such a configuration, the attitude of the mirror is adjusted by rotating the operating lever around its axis via the coupling mechanism, for example, and the operating lever is rotated around its axis. By tilting around the fulcrum, the posture of the mirror can be adjusted by rotating around the Y-axis, for example, and when the mirror visor is rotated by an external force, the coupling mechanism will cause the protrusion to come out of the engagement recess. When the mirror visor comes off and the two are disengaged, the mirror visor can be rotated, for example, around the Z-axis, without any hindrance, and when the mirror visor is returned to its normal position, the engagement of the coupling mechanism is restored again. .

(Examples) The present invention will be specifically described below with reference to some examples shown in the drawings.

It is tiltably supported by a mounting plate 16 attached to the mirror visor 2 via the mirror visor 5 .

Reference numeral 21 denotes an operating lever, which passes through the mirror stay 1 from the inside of the vehicle 4 toward the mirror visor 2, and supports a spherical portion 22 with a spherical bearing 24 formed by the mirror stay 1 and a bush 23 attached thereto. As a result, the operating lever can be rotated around its axis (in the direction of arrow N in the figure) and tilted about its axis using the spherical portion 22 as a fulcrum (in the direction of arrow M in the figure). installed. At the tip of the operating lever 21, a coupling member 25 on the lever side rotates integrally with the operating lever 21 so as to be unrotatable about its axis with respect to the operating lever 21, and is connected to the operating lever 21 in the direction of the axis. is slidably attached, biased toward the distal end by a compression spring 26, and prevented from coming off by a set screw 27. Further, a coupling member 28 on the mirror side is integrally formed in the mirror holder 14 in correspondence with the coupling member 25, and this pair of coupling members 2
