Description

[Detailed Description of the Invention] The present invention relates to a rear endoscope with a canopy in which the mirror can be easily attached using a part of the frame body.

A button on the rear view mirror of a car with a canopy attached integrally to the front, top, and rear of the mirror surface for anti-fog, anti-dust, or anti-glare purposes is commonly used in general passenger cars, but compared to those installed on freight cars, etc. As is well known, a large-sized rear endoscope with this shape has not yet been put into practical use.

One of the reasons for this is that the mirrors are large in size, making it difficult to form them into an elegant appearance similar to those used in passenger cars, and the mirrors are expensive to manufacture, making them impractical.

In this invention, the structure of the rear scope body is the same as the conventional one, with the back plate bulging into the desired shape, and the outer end of the mirror is fitted into the peripheral edge of the back plate to receive and support it. The endless frame, which integrally fixes the mirror and the main body by fitting and supporting the peripheral edge, is made of soft plastic, resin, or rubber material. It has a circumferential groove to be fitted to the peripheral edge of the main body, and a tongue-shaped mirror pusher protrudes over the entire length from the inner surface of the fitting groove facing the mirror, On the other side, a fitting groove is provided on the outside that opens narrowly forward and forms a space with a circular cross section all around the inside, and the base end is formed into a beaded edge on the front surface of the upper half of the frame. A flexible synthetic resin canopy formed so that the upper part projects longer than the side parts is fitted along the fitting groove of the frame body.

Embodiments of the present invention will be described below in detail with reference to the drawings. What is shown in FIGS. 1 to 3 is one specific example, and the rear endoscope body 1 is formed by bulging a metal plate into a suitably shaped back plate. The peripheral edge 3 that shapes the outer shape is formed into a flat portion 3 with an appropriate width according to the shape and dimensions of the mirror 5, and is bent to a height corresponding to the thickness of the mirror 5 to form a receiving edge y. A supporting piece (not shown) of a metal fitting is fixed to the back of the back plate 2 by a well-known method.

The mirror 5 is a flat portion 3' forming the peripheral edge 3 of the body 1.
It fits into the area surrounded by the receiving edge y and is supported and supported.

A frame 10 for fixing the main body peripheral portion 3 and the mirror 5 fitted and supported therein is made of a material with high elasticity and weather resistance, such as soft vinyl chloride resin or synthetic rubber. A fitting groove 11 is formed on the inside to surround the peripheral edge 3 of the main body 1 in a tight fit, and a tongue-shaped groove is formed on the side surface facing the mirror 5. A pressing piece 12 that is gradually thinner toward the tip is provided protruding over the entire circumference, and a space portion with a circular cross section that opens toward the front side is formed over the entire circumference at the outer position opposite to the fitting groove 11. A fitting groove 13 is provided, and a mirror 5 fitted with the peripheral edge 3 of the main body 1 as shown in the first figure is fitted into the fitting groove 11 and fixed together with a frame 10.

As shown in FIG. 4, it has a total length corresponding to the expanded length of the frame 10 of the upper half of the rear scope, and is shaped in an appropriate curve so that the middle part is wider than both ends. A thin eave piece 20 is formed from a flexible synthetic resin with an edge 21 drawn and a base end formed as a bead 22, and this eave piece 20 is inserted into the fitting groove 13 of the rear view mirror frame 10. Insert the 22 parts of the bead as shown in the third figure, so that the wide part in the middle is mirrored.
5. It is installed along the fitting groove 13 so as to surround the upper part.

With this configuration, the rear endoscope of the present invention can adapt the frame to the external shape of the mirror, even if it is a conventional large mirror or a mirror commonly used in freight cars. In this way, when the fitting groove 11 is fitted into the main body side peripheral part 3 by raising the temperature at the time of assembly to make it easy to expand, it contracts as it cools and comes into close contact with the main body 1. A tongue-like pushing piece 12 is provided in the fitting groove 11 of the body 10, and as shown in FIG. By bending the bent eaves piece 20 along the fitting groove 13 and fitting the bead 22 part, the frame body 10 is tightened by squeezing the fitting groove 11 inside the frame body 10 from the outside. The attachment effect is enhanced, and the eaves piece 20 is also attached to the frame 10.
It can be fixed to the frame 10 and has a beautiful appearance and exhibits anti-glare, dust-proof, or anti-fog effects.In this way, a part of the frame 10 is provided with a mounting groove and peeled off, and a separately made eaves piece is attached to the frame 10. Since it became possible to obtain a rear endoscope with a canopy simply by bending it into the desired shape and attaching it, it became possible to manufacture it at low cost, and even large-sized items could be manufactured easily, making it suitable for vehicles other than passenger cars. This resulted in great practical effects for use in automobiles.

According to the spirit of the present invention, the rear endoscope itself is not limited to the above-mentioned embodiments, and the rear endoscope itself can have any shape with a canopy.
It goes without saying that the size and shape of the canopy piece can be selected as desired, and even if the button breaks during use, it can be replaced with a new one, and even if the canopy piece is removed when not in use, it still functions as a rear endoscope. will not be damaged.
