JPS59164244A - Attaching device for drop-out type mirror for vehicle - Google Patents

Abstract

PURPOSE:To make it possible to simply and surely carry out the drop-out of a mirror stay, by attaching, to a vehicle body, a securing member which is held in an attaching hole formed in a mirror stay, so that the securing member is deformed when external force applied thereto, thereby it comes off from the attaching hole. CONSTITUTION:A securing member 5 is fitted in an attaching hole 4 that is formed in a mirror stay for supporting at its free end a room mirror, in the mounting part of the mirror stay which is attached to a vehicle body. A female screw thread 4a is formed in the attaching hole 4, and a screw hole 6 is formed in the bottom of the hole 4. Further a male screw thread 5a which is threadedly engaged with the female screw thread 4a is formed in the securing member 5 which has inner and outer cylinders 5b, 5c in a doubled-shape, the outer cylinder 5c being formed with a plurality of notches 7 for ease bend. Upon assemblying the securing member 5 which is beforehand screwed in the attaching hole 4, is attached to a plate in a vehicle body by a screw 8. When external force is applied to the mirror stay 1, the securing member 5 is deformed so that it comes off from the attaching hole 4, resulting in that the mirror stay 1 drops out.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device for a removable mirror for a vehicle that is mounted diagonally above a driver's seat.

This type of removable mirror is designed to fall off if the head or face of the driver or passenger hits the driver or passenger during a sudden stop or collision, preventing injury. However, the structure of the mounting part tends to be complicated because it needs to be firmly mounted to a certain extent to prevent it from falling off or changing the mounting angle to the vehicle body due to normal vibrations or external forces when adjusting the mirror. It is something. For example, Utsukai 56-
The device disclosed in No. 96402 requires parts such as a base and a bracket in addition to two leaf springs.
Also, fixing the leaf spring to the base, fixing the base to the vehicle body,
The number of parts that require fixing work, such as fixing the bracket to the mirror stay, has increased, the structure is complex, the number of parts is large, and the assembly is time-consuming.

The present invention has focused on this point, and has been devised for the purpose of providing a mounting device for a removable vehicle mirror that has a simple structure, a small number of parts, and is easy to assemble. A mounting hole is provided in the mounting portion of the holder, and a fixing member is provided to be inserted into the mounting hole, and at least one of the mounting hole and the fixing member is made of an elastic material, and the fixing member is inserted into the mounting hole by screws or by engaging the protrusions and recesses. The mirror stay is attached to the vehicle body by holding the mirror stay and fixing the fixing member to the vehicle body. The fixing member is held in the mounting hole with such strength that when a force exceeding a certain limit is applied, the fixing member separates from the mounting hole due to deformation of the elastic material. The stay is attached to the vehicle body so that it does not fall off. Therefore, according to the present invention, the assembly can be completed by attaching the fixing member to the mounting hole and fixing the fixing member to the vehicle body, which is different from the conventional example described above. In comparison, the structure is extremely simple and assembly is easy.

Hereinafter, the present invention will be specifically explained with reference to illustrated embodiments.

Figures 1 and 2 show the first embodiment, and in the figures (
1) is a mirror stay that supports a room mirror (not shown) at the tip, (2) is a vehicle body plate, and (3) is a mirror stay (
1) is a mounting portion to the vehicle body, (4) is a mounting hole, and (5) is a fixing member. The access hole (4) is a female screw hole provided on the side of the mounting portion (3) that contacts the vehicle body, and a screw hole (6) is formed in the bottom. The fixing member (5) has a mounting hole (4
) has a male thread (5a) that is screwed into the female thread (4a), and the inner cylinder (5b) and outer cylinder (5C) are connected at one end, making it easy to bend ( A plurality of notches (7) are formed in the outer cylinder (5C) for this purpose.

The fixing member (5) is made of an elastic material such as hard rubber or flexible synthetic resin. [
81 (9) are screws and nuts for mounting, and 00) are protrusions for positioning.

Assembly is performed as follows. That is, first screw the fixing member (5) into the mounting hole (4) and attach the mirror stay (1).
Attach to. Next, set the protrusion (10) in a predetermined position on the vehicle body plate (2), and insert the screw (8) into the screw hole (
6) and the fixing member (5) and screwed onto the vehicle body plate (2).

In this way, the mirror stay (1) is attached to the vehicle body plate (2), and if a large external force is applied to the mirror stay (1) for some reason, the fixing member (5) will deform and the female thread (
4a )" and the male screw (5a), the fixing member (5) comes off from the mounting hole (4) and the mirror stay (1)
) will fall off. The magnitude of the external force that causes the mirror stay (1) to fall off is determined by the bonding force between the mounting hole (4) and the fixing member (5), so the flexibility of the fixing member (5) and the screwing In consideration of the fact that the fixing member (5) is compressed in the axial direction, the diameter becomes slightly larger and the bonding force becomes stronger, the dimensions and thread shape of the female thread (4a) and male thread (5a) are adjusted appropriately. All you have to do is select it.

Figures 3 and 4 show a second embodiment, in which a fixing member (11) is manufactured by press-forming a metal plate made of spring material.
An example using . That is, the fixed member (11)
is a base part (lla) with a screw hole (12) in the center
Three elastic pieces (flb) are formed around the cylindrical shape as a whole, and a threaded protrusion (IIC) is provided at the tip of the elastic piece (llb).
into the mounting hole (4) of the mirror stay (1), and tighten the screw (
8), it has a structure in which it is screwed to the vehicle body plate (2). Normally, the male thread protrusion (IIC) is female thread (4a
) and hold the mirror stay (1),
If the external force exceeds the limit, the elastic piece (llb) will bend and the screw will disengage, causing the mirror stay (1) to fall off, and the strength of the engagement between the male screw protrusion (IIC) and the female screw (4a) will be appropriate. The shape of the screw and the elastic contact force of the elastic piece (llb) may be set so as to achieve the desired value.

In each of the above-mentioned embodiments, the fixing member (51 (11)) is made of an elastic material. It is also possible to fix the member and hold it removably between the screws used for installation, so that the mirror stay side can be made of an elastic body, or both can be made of an elastic body.Furthermore, the fixing member (11)
The externally threaded protrusion (IIC) may be formed not only at the tip of the elastic piece (llb) but also on the entire elastic piece (llb), for example, so that it has a shape like the cap of a light bulb.

Note that although only the example 41 above is shown in which the fixing member and the mounting hole are threaded pairs, the relationship between the two does not necessarily have to be threaded pairs. It is also possible to combine them.

As described above, the present invention provides an upper Lr1. By configuring at least one of the TPyI + Umuda window members with an elastic material, the elastic material deforms and the fixing member comes off from the mounting hole in response to an external force exceeding a certain limit, and the structure It has the advantage of being simple, having a small number of parts, being easy to manufacture, and being easy to assemble.
