Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved mounting device for a rear endoscope mainly used in freight cars, passenger cars, etc.

For vehicles such as freight cars, where the external shape of the vehicle body is less important than passenger cars, and where emphasis is placed on functionality, it is of course important for driving. However, the functionality of the rear endoscope as an accessory device is the main focus, and it is also required to be economical. The structure is such that it is attached to a support bracket at the center of the back of the vehicle to ensure stability, so naturally the support arm must be extended outward from the vehicle body to attach it.
In order to satisfy this requirement within the scope of legal regulations for vehicles, the external shape of the vehicle sometimes becomes disproportionate and has a poor design, and the influence that the mechanical structure of the rearview mirror alone has on the vehicle as a whole is negligible. It's a victory for me.

In view of this situation, this invention not only improves functionality, but also
To provide a device that can be rationally attached to a support body as a rear endoscope that not only improves the appearance of a vehicle when the rear endoscope is attached, but also has an excellent appearance even when the rear endoscope is used alone. be.

In the present invention, a support piece with an annular holding groove carved at the tip is attached to the side of the main body of the rear scope, and a support arm connecting this support piece and the rear scope support is made of a metal plate. It is a combination of three symmetrical press-formed pieces of appropriate length, with the base end having a concave curved inner surface forming part of a spherical surface, and the tip end having three pieces that are cylindrical. The distal end is bent in the direction of the axis, and the bent part is fitted into the holding groove of the support piece attached to the main body, and the base end part can be fitted in any position of the support. An annular synthetic resin holding piece with a spherical outer circumferential surface and a notch on the inner surface that can be expanded by cutting out a part of it is interposed, and the three pieces are bolted together at the middle part of the supporting piece. By fastening the rear end mirror to the support, the direction of the mirror surface can be set and maintained in any desired state, and the support can be mounted close to the side of the vehicle body so that it can be mounted in a stylish and stable manner.

Below, the present invention will be described in detail with reference to drawings regarding one embodiment.
The one shown in FIG. 1 is a rectangular rear scope, in which the body 2 of the rear scope 10 is made of synthetic resin, for example, and is shaped into a desired shape to create an aesthetic appearance. A flat surface 3 is formed on the flat surface 3. A flat mounting seat 5' is fastened to the main body 2 with rivets 4, etc., and a support piece 5 is provided to protrude horizontally. The tip is circular and has a relatively short protrusion 6 with a narrow annular groove 6' slightly rearward from the tip.

The support arm 10, which supports the rear endoscope 1 by connecting the support piece 5 fixed to the main body 2 and the support 20 provided close to the vehicle body, has an appropriate length as shown in FIGS. 2 to 4. It is made up of three symmetrical pieces press-molded from a metal plate, and the base 11 has an inner surface formed into a spherical concave curved surface 11'9, and the tip 12 forms part of a cylindrical shape, with the tip facing toward the center of the axis. The support piece 5 is bent at right angles to engage with the annular groove 6' of the support piece 5, and the middle part is provided with a rest 13 inside along the axis line to increase cross-sectional strength. A bolt hole 14 and a piece formed with a tightening seat 14 are arranged facing each other at the center position, and the tip bent part 12' is engaged with the annular groove 6' of the support piece 5, and the base part Inside 11 is an annular ring made of highly lubricating synthetic resin with a part cut out 22 so that it can be fitted at any position on the outer periphery of the pipe forming the support 20, and whose outer periphery 21' is formed as a part of a spherical surface. holding piece 2
1 and fastened with a bolt 15 inserted through the bolt hole 14 in the center of the support arm 10, the holding piece 21
and the support piece 5 are simultaneously tightened and fixed.

Note that a notch 23 of an appropriate depth is provided on the inner surface of the holding piece 21 at a position opposite to the incision 22, so that when the holding piece is opened from the incision 22 and fitted to an arbitrary position of the support 20, the notch 23 is formed at a position opposite to the incision 22. 23 serves as a hinge, and the outer peripheral spherical surface is designed to approximately match the concave curved surface inside the base 11 of the support arm 10.

With this configuration, the support 20 is provided close to the vehicle body, the holding piece 21 is first attached to an arbitrary position of this support 20, and the two-piece base 11 of the support arm 10 is attached to this holding piece 21. Fitted and bent portion 12' of the tip portion 12
The rear endoscope 1 is attached via the support piece 5 by engaging with the annular groove 6' of the support piece 5 and fastening the bolt 15. By adjusting the contact force between the inner surface and the holding piece 21, the rear endoscope 1 is held at the set position via the support arm 10 as long as the rear endoscope 1 is not moved by an external force due to the frictional resistance between the two.

By doing this, when adjusting the clear viewing angle of the mirror, you can hold the main body 2 and hold the holding piece 21 and the support arm
It can be freely displaced and adjusted along the spherical surface with the base 11,
Handling is also significantly easier.

Of course, when an abnormal external force acts directly on the rear scope 1, the support arm and the main body will rotate from the holding part within an allowable range, and the rear scope will not be damaged and will come into contact with the rear scope. It does not cause any hindrance to what is done.

Furthermore, regarding the configuration, as explained in the above embodiment,
Since the structure is such that it can be installed by sandwiching the support and a support piece protruding from the side of the rear scope main body and connecting and fixing them, the external shape of the main body can be given the desired shape or pattern. Therefore, by making the shape elegant or original and adding various patterns to it, it became possible to obtain a beautiful and functional rear mirror that was not available in conventional products. .

The rear scope is attached to the support arm by engaging the annular groove at the tip of the support piece attached to the side of the main body, so by loosening the contact state at the engagement part with this groove when tightening, the displacement of the support arm can be changed. It is suitable for irregularly mounting a large mirror such as a left-turn rear mirror on a large vehicle, for example.

! The outer shape of the main body of the rear endoscope is not limited to the shape shown in the above embodiment, but it is also possible to form it into any shape from a thin metal plate if necessary. do not have.

Further, the engagement between the annular groove of the support piece and the support arm may also be made into a rectangular cut to determine the displacement angle.

Furthermore, the exterior of the support arm can be covered with a flexible cover as needed to further improve the design, and a mounting mechanism for the rear endoscope with unprecedented functionality and aesthetic effects has been obtained. be.
