Description

[Detailed Description of the Invention] The present invention relates to a mounting device for a mirror mounted on a vehicle body panel, such as an automobile bank mirror for mounting on a fender, and particularly relates to a mounting device that absorbs external shocks.

In the general structure of mirrors attached to automobile body panels, the base of the mirror stay is attached to the panel surface, and the tip of the mirror usually protrudes from the panel.
For this reason, if the holding rigidity of the mirror mounting device is too strong, there is a high possibility that personnel, equipment, etc. that collide with the mirror will be seriously damaged.

For this reason, a collapsible type of mirror mounting device that has the ability to absorb external force is often used, and when the mirror is subjected to external force, the stay is structured so that it collapses against the elastic force. Here, a conventional example of a foldable mounting device for a fender mirror will be explained with reference to FIGS. 1 and 2.

The mounting hole 1a of the panel 1 has a cover plate 2 made of a collar-shaped ring.
The shaft portion 2a of the panel 1 is fitted onto the seat plate 2, and the hem edge of the mirror stay 4 that holds the mirror body 3 is placed flat, and the shaft portion 2a protruding from the back side of the panel 1 has a back support. A plate 5 is press-fitted from below and fitted externally.

Further, the upper end of a pin 7 is pivotally connected to the center of the bottom of the stay 4 by a pin 6 joint, and a lock nand 8 is engaged with the threaded portion 7a of the bolt 1, and furthermore, the lock nand 8 is fitted inside the lock nand 8. In this case, a one-shoe 9 is interposed.

A plurality of locations around the one-shoe 9 are bent upward to form claws 9a, and a compression coil spring 10 is sandwiched between the outer periphery of the claw 9a and the lower surface of the back support plate 5. equipped.

Next, a cylindrical case 11 whose top surface is open is inserted from below around the coil spring 10, and protrusions 11 are protruded from two places on the circumferential surface near the top end of the case 11.
a is press-fitted and locked into the engagement hole 5b of the side surface 5a of the back support plate 5.

In the conventional mounting structure configured in this way, the stay 4 is pulled downward by the elasticity of the coil spring 10.
As a result, in a normal state where no external force is applied to the mirror, the stay 4 is held on the panel 1 in the illustrated state with its bottom surface pressed against the seat plate 2.

However, when an external force is applied to the stay 4, the spring 1
Bolt 7 is pulled up while retracting 0, and as a result,
The stay 4 tilts in the direction in which the external force is applied and acts to absorb the external force.

However, such a conventional structure has the following drawbacks.

(a) 'y-s11. Since the washer 9 and the like are used, the number of parts increases, resulting in high cost, and the task of attaching and detaching the mirror becomes more troublesome.

(b) In order to attach the case 11, the diameter of the back support plate 5 becomes large, and a large space is taken up inside the panel 1.

) (c) Because of the case 11, only the Bonks tool can be used to tighten the lock nand 8.

The present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a mirror mounting device that has a simple structure and is easy to attach and detach.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

In the mounting device of the embodiment, as shown in FIGS. 3 to 6, the stay 4 of the mirror body 3 is mounted flat on the seat plate 2 fitted into the circular mounting hole 1a of the panel 1, as described above. It is placed.

The seat plate 2 is a collar-shaped ring body made of rubber-like material, and includes a short cylindrical shaft portion 2a that fits into the mounting hole 1a, and an underframe that receives the bottom edge of the stay 4. It has an integral bottom shape, and a back support plate 12 press-fitted from below is fitted onto the shaft portion 2a.

This back support plate 12 is a rectangular plywood board having side surfaces 12a, and has a hole 12 in the center of its upper surface through which the shaft portion 2a passes.
c is opened, and an elongated engagement hole 12b is bored near the center of the side surfaces 12a facing each other, and the lower edge of the engagement hole 12b of the side surface 12a extends outward as it goes downward. It is formed to be inclined.

Next, a fork 4a is formed at the center of the bottom surface of the stay 4, and the upper end of the bolt 1 is pivotally connected to this fork 4a by a pin 6 joint.

Therefore, the threaded portion 7a of the bolt 7 has a locking nut 8.
are engaged with each other, and a compression coil spring 13 is sandwiched between the nut 8 and the back plate 12.

The upper end turn 13a of this coil spring 13 is locked into the engagement hole 12b by press fitting due to its elasticity, and
A folded portion 13b shaped to sandwich the bolt 7 is formed in the lower end turn (FIG. 6), and the folded portion 13b is pressed against the upper end surface of the pad 8.

Note that the folded shape of the lower end turn is similar to that of the folded part 1 shown in FIG.
4, it may be shaped to surround the pole 7.

In addition, a guide tube 15 that loosely fits around the bolt 7 is inserted into the middle part of the bolt 7, but the function of this guide tube 15 is to insert the back support plate 12 and the spring 13 when assembling the mirror. It is intended to facilitate the process and is not necessarily required for functionality.

In terms of function, the mounting device of the Jishima example configured as described above absorbs the external force based on the compression of the coil spring 13 when an external force is applied to the stay 4, similar to the above-mentioned conventional device. However, the installation and removal work is extremely easy. That is, when inserting the back support plate 12 and the coil spring 13 from the back side of the panel 1, the coil spring 13 is guided by the inclined part of the side surface 12a of the back support plate 12. Since the spring 13 is easily locked into the engagement hole 12b of the back support plate 12, the operation is as simple as tightening the Nand 8. Furthermore, tightening the Nand 8 does not require an ordinary spanner. It can be used.

In addition, as a technology similar to the proposed structure,
There is a proposed structure called No. 6690, but in this proposed structure, when assembling the coil spring, the end of the spring must be screwed in, so the assembling operation is extremely difficult.

As described above, according to the mirror mounting device according to the present invention, the coil spring that absorbs external force is directly locked to the back support plate, and the coil spring is directly tightened by the lock nand. This eliminates the need for spring cases and locks, which reduces the cost of the mounting device and simplifies assembly work.Furthermore, the spring attached to the mounting device can be held without being removed.
This has the effect of improving the practicality of the mounting device, such as by making it possible to reduce the mounting space.
