Abstract

PURPOSE:To retain a visor in a prescribed posture by the simple constitution by installing a nodal mechanism for retaining the visor at a neutral or an inclined position onto a front-side rotary-shaft part or a rear-side rotary-shaft part, in a double-hinge type outer mirror. CONSTITUTION:A visor 1 is supported rotatably rearward around a rear-side rotary-shaft part R and rotatably forward around a front-side rotary-shaft part F. In the ordinary using state, nodal balls 13 are engaged with the nodal hole 15 on a nodal plate 10, and a hinge rod 20 is held at a neutral position, fitted into a clamper 23. When a backward external force exceeding the retention force is applied onto the visor 1, the nodal balls 13 come-off from the nodal hole 15 against the contact-pressing force of a belleville spring 17, and a hinge plate 5 can be turned with the visor 1, which is tilted backward.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for attaching a visor to a stay via a hinge plate.
This example relates to a device.

The double-hinged outer mirror has a visor that holds the mirror attached to a stay via a hinge plate. The visor is supported so that it can be tilted, and it is maintained in the neutral position, which is the normal use state as an outside mirror. It has a built-in holding mechanism to keep it in a tilted position to prevent it from popping out and avoid collisions when parking.However, due to the built-in mechanism, the stay tended to be thicker or larger. However, in order to ensure the effective area of the mirror, the amount of protrusion in the lateral direction becomes large, increasing the possibility of contact with spectators, and is also undesirable in terms of design.

The present invention has focused on these problems, and has been made with the object of providing an outer mirror folding device that does not require a large thickness of the stay and is capable of holding the visor in a predetermined position with a simple structure. The double hinge type outer mirror as described above is characterized in that a moderation ti mechanism is provided on one or both of the front rotating shaft portion and the rear rotating shaft portion to hold the visor in the neutral position and the tilted position.

The following is an example of a horizontally long type door mirror.
The present invention will be specifically explained.

Fig. 1 is a perspective view showing the overall appearance, Fig. 2 is a front view of the hinge portion, and Fig. 3 is an exploded perspective view of the hinge portion.
is a visor, 2 is a mirror, 3 is a stay, 4 is a stay cover, and 5 is a hinge plate. The mirror 2 is supported by the visor 1 so as to be tiltable vertically and horizontally by a well-known mechanism, and the stay 3 is fixed to the door of the vehicle using a mounting hole.

On the visor side of the stay 3, bearing parts 7.7 are protruded on the upper and lower rear sides, and the bearing plates 8.8 of the hinge plate 5 are rotatably attached to each other by rivets 9, 9, It constitutes R. ? A moderation plate 10 is stacked on the bearing part 7 in a state where it is prevented from rotating by a combination of a notch 11 and a lug 12, and a moderation hole 13 is inserted between the moderation plate 0 and the bearing plate 8. moderation ball 1
3 is held by a holding hole 14''C recessed in the lower surface of the bearing plate 8, and the moderation plate 10 has a moderation hole 15 for a neutral position corresponding to this holding hole 14 and a moderation hole 15 for a smaller tilted position. A moderation hole 16 is provided, and the bearing plate 8 is pressed against the moderation plate 1 ( ) with a constant force via the moderation ball 13 by the biasing force of a disc spring 17 fitted into the rivet 9. A hinge rod 20 is attached to the visor 1 with a screw 21 at a position coaxial with the rear rotating shaft R. Correspondingly, a clamper support piece 22 is provided on the visor 1, and a bearing-like clamper 23 is attached to the insertion piece 24a. and insertion hole 2
4b and the screw 25. Reference numeral 26 indicates a pin for removing the rivet 9.

A bracket 29 is protruded from the front of the stay side of the visor 1, and bearing protrusions 30°30 are formed on the top and bottom of the bracket 29. J31 is rotatably attached by a shaft pin 32, and constitutes a front rotating shaft portion F. The shaft portion 31 has a total length smaller than the spacing between the bearing protrusions 30, 30, is movable in the axial direction, and is biased downward by a coil spring 33.

The present embodiment has the above-described structure, and the visor 1 is supported so as to be rotatable rearward about the rear rotation shaft R and rotatable forward about the front rotation shaft F. However, under normal usage conditions, moderation ball 13 force 1 degree plate 1
0, and the hinge rod 20 is fitted into the clamper 231 to be held at the neutral position. When a backward external force exceeding the holding force is applied to the visor 1,
The moderation ball j3 engages the moderation hole against the pressure force of the disc spring 17]
5, the hinge plate 5 becomes rotatable, and rotates together with the visor 1 in an upwardly lifted state, causing the visor 1 to tilt rearward. When the visor 1 is tilted to a position where it is substantially parallel to the side surface of the vehicle, the moderation ball 13 engages with the moderation hole 16 and the visor 1 is held in the tilted position. On the other hand, when an external force of a certain value or more is applied in the direction of tilting the pie and the 1 forward, the hinge rod 20 separates from the clamper 23 and the visor 1 becomes able to rotate forward.

In this embodiment, since the purpose of forward tilting of the visor 1 is to alleviate shock, no holding mechanism is provided in the forward tilted position.

In the above-described embodiment, the moderation mechanism of the rear rotating shaft R is constituted by a combination of the moderation plate 10 having moderation holes 15 and 16 and the moderation ball 13, but other structures may be adopted as the moderation mechanism. For example, as shown in FIG. 5, one of the mutually opposing surfaces of the bearing portion 7 and the bearing plate 8 may have a protrusion 35 having a chevron-shaped cross section, and the other side may have a gate groove 36 having a V-shaped cross section. They can be formed radially and combined. Further, in the embodiment, moderation mechanisms are provided on both the upper and lower sides of the rear rotating shaft portion R, but the moderation mechanisms may be provided only on either the upper or lower side.

In addition, the disc spring 17 may be a coil spring, and any suitable structure may be adopted, such as using a retaining ring or caulking to prevent the rivet 9 from being removed, rather than using the pin 26.

Fig. 6 shows an embodiment in which a moderation mechanism is provided on both the rear rotating shaft R and the front rotating shaft F, and in this case, the hinge rod 20 and clamper 23 to prevent forward tilting are unnecessary. It is.

That is, the moderation plates 10 are stacked non-rotatably on the upper and lower bearing parts 7゜7 of the rear rotating shaft part R, respectively, and the upper hinge plate 5a and the lower Hinge play) 5b is inserted and supported for rotation by the waist shaft 4(),
Further, the bearing protrusion 30 of the front rotating shaft portion F. '3 (l), stack the moderation plate 10 non-rotatably on one side of the spring 41
Insert the upper hinge plate 5a and lower hinge plate 5b interposed between the bearing protrusions 31) and 30, and
It is rotatably supported by. A moderation mechanism using a moderation ball or an uneven surface is provided between the moderation plate 10 and the hinge plays 1, 5a, 51).

The second embodiment is constructed as described above, and is held in the neutral position by the moderation mechanism of both the rear rotation shaft R and the front rotation shaft F, and the rear rotation shaft R and the front rotation shaft F are held in the neutral position. Holding in this position is carried out by the moderation mechanism of the rear rotating shaft (F), and holding in the forward tilted position is carried out by the moderating mechanism of the front rotating shaft (F).

As is clear from the description of each embodiment above, the present invention provides a double-hinged outer mirror with a moderation mechanism that holds the visor at the neutral position and the tilted position on one or both of the front rotation shaft portion and the rear rotation shaft portion. The visor can be held in a predetermined position by a small and simple moderation mechanism, which reduces the thickness of the stay and downsizes the entire outer mirror, while also achieving a well-balanced design. This makes it easier to create a new model.
