Description

[Detailed description of the invention] The present invention relates to a structure for holding the 5-layer in the rearview mirror of an automobile, and is designed to securely hold the 5-color with a single touch without using any means such as gluing or welding. This is an improved version.

A normal rearview mirror has a cushion tape-like material attached to a step formed inside the periphery of the housing.1. After absorbing the irregularities on the peripheral edge of the mirror glass and arranging the 5-layer, a ring with an inverted U-shaped cross section was placed on top of the protrusion provided on the upper edge of the housing while holding down the periphery of the mirror glass. .

Welding is performed by applying ultrasonic waves or high frequencies.

In such a case, the peripheral edge of the mirror may shrink and crack due to the thermal effect during welding.

Another mirror holding structure is to fit the fitting groove of a dish-shaped holding plate made of thermoplastic material into the surrounding wall of the housing, load the mirror on the entire surface of the dish-shaped holding plate, and then It is also known that the periphery is curled to hold the 5-ra, but since the periphery of the 5-ra and the periphery of the housing are directly pressed and stress is introduced, the mirror can be damaged by vibrations when the vehicle is running. There were drawbacks such as being easy to use.

Here, the present invention engages a plurality of holders inside the fitting groove of the mounting ring, holds the mirror between the ring and the holder, and fits this into the opening edge of the rigid housing. This eliminates the above drawbacks.

In other words, one invention is between the fitting groove of the mounting ring and the housing opening edge.

A plurality of holders having a U-shaped cross section with both sides connected at the bottom are glued together, protrusions with the stopping direction upside down are formed on the inner and outer surfaces of the outer sides of the holders, and one protrusion is attached to the inner wall of the mounting ring. The projection is engaged with a window hole drilled in the opening, and the other projection is engaged with a window hole raised on the edge of the opening.

By using a holder with a protrusion for preventing removal, the mirror can be attached with one touch without using cushion tape or adhesive welding.

Next, the present invention will be specifically explained with reference to the drawings.

Figure 1 is a perspective view of the back 8 roller, in which 1 is a housing made of a hard material and molded into a roughly dish shape, 2 is a mounting ring made of thermoplastic such as polypropylene or polyethylene, and is compared with the inner wall 3. It has a substantially inverted U-shape cross section with a thin outer wall 4 connected at the top and a fitting groove 5 formed inside.

6 is a step formed on the inner wall 3 of the mounting ring, 1 is a plurality of holders inserted into the inside of the mounting ring 2, and 8 is a step 6
5 and 9 are stays held at the inner upper end of holder 1.

As shown in Fig. 4, the holder 1 has a U-shaped cross section by connecting a long outer side 10 and a short inner side 11 at the bottom. It has projections 12 and 13 for preventing removal.

The outer protrusion 13 is formed to fill the entire width of the holder 7, while the inner protrusion 12 is formed with a narrow width closer to one end.

On the one hand, the opening edge 14 of the housing 1 is provided with a plurality of window holes 15 for engaging the outer protrusions 13 of the H/L/turf, and on the other hand, the inner wall of the mounting ring 2 is provided with the holder 7.
A window hole 16 is provided for engaging the inner protrusion 12 of.

In addition, a fitting groove 5 formed between the inner and outer walls 3 and 4 of the mounting ring 2
In the part where the holder 7 is not placed, the gap is sufficient to fit the opening edge 14 of the special housing 1 shown in FIG.
As shown in the drawings and FIG. 5, the stepped groove 11 is such that the outer side 10 of the halter and the opening edge 14 of the housing can be fitted into each other.

To assemble the above-mentioned back S-sea, first, the mirror 8 is inserted from below the opening of the mounting ring 2, and the peripheral portion of the mirror is pressed against the stepped portion 6 of the mounting ring to be gripped elastically.

Next, the holders 7 are inserted into predetermined positions of the fitting grooves of the mounting ring 2, respectively.

The inner wall 3 of the mounting ring at the holder insertion position has a window hole 16 as shown in FIG. Since a stepped groove 1T into which an object can be fitted is formed, the holder 1 is inserted so that the inner wall 3 of the mounting ring is sandwiched between the inner and outer sides 10° 11 of the holder 1.

When inserting the holder f-7 into the inner wall 3 of the mounting ring 2, it is guided by the inclined side of the inner protrusion 12 of the holder, and the protrusion itself deforms as it passes the inner lower end of the mounting ring.
By further pushing in, the protrusion 12 returns to its original shape and engages with the window hole 16.

Since the protrusion 12 has a downward restraining surface, once it is engaged, it will not come off unless a strong external force is applied to separate it.

On the other hand, the upper end of the inner side 11 of the holder 1 is assembled so as to be close to or in contact with the lower part of the periphery of the mirror 80 held by the stepped portion 6 of the housing.

Next, when the mirror-shaped mounting ring 2 is pressed against the opening edge 14 of the housing 1, the outer protrusion 13 of the holder engaged in the groove of the mounting ring and the opening edge 1 are pressed together.
The window hole 15 of No. 4 is engaged and firmly fitted.

Since the outer protrusion 13 has a stopping surface that is in the opposite direction to the inner protrusion 12, once it is fitted, the ring 2 and housing 1 cannot be separated even if the mounting ring 2 is pulled upward. There isn't.

The illustrated embodiment A has two holders 7 on each side of the housing.
Although the case where eight pieces are attached in total is shown, the number of pieces attached is not limited to what is shown in the figure, such as one on each side or two on opposite sides.

In addition, the inner and outer protrusions of the holder do not need to be properly aligned with the width of the window hole on the housing and mounting ring side, and may be sized and shaped so that they can be engaged in the 0-distance direction of the window hole without any problem. .

As mentioned above, according to the present invention, a plurality of holders having a U-shaped cross section are sandwiched between the fitting groove of the attaching ring and the opening edge of the housing by connecting both sides at the bottom part. ,
Place the 5-layer using cushioned tape,
There is no need to glue or weld the housing and the ring, and the mirror can be easily held.

In addition, the holder has a pullout stopper and a protrusion formed on the inner and outer surfaces of the outer side with the stopping direction upside down, and one protrusion is engaged with a window hole made in the inner wall of the mounting ring, and the other protrusion is inserted into the hole. Since it is engaged with the window hole raised on the edge of the housing opening, when assembling the mirror, it can be smoothly engaged with the window hole along the sloped side of the protrusion, and once engaged, it can be pulled out from the mounting ring and housing. This has the advantage that the mirror can be held securely without coming out.
