Description

[Detailed description of the invention] This invention is a stop that is used to prevent traffic accidents by making the following cars aware of the presence of an unforeseen accident or breakdown on a highway, etc. This relates to signboards.

The stop sign board has a warning reflector plate that is a combination of reflectors in a triangular shape.

A reflector is constructed by joining a reflecting plate and a frame body, and a suitable empty space is provided inside the joint between the reflecting plate and the frame body, and the reflective surface of the reflecting plate faces this empty space. This is important for increasing reflected radiation.

If water, dust, etc. enter this cavity and adhere to the reflective surface, the reflective effect will be significantly reduced.

For this reason, conventionally the reflector was bonded to the frame by ultrasonic bonding.

Furthermore, Japanese Utility Model Publication No. 53-24229 discloses a step structure in which the entire circumference of the reflector constituting the reflector and the frame are easily sealed, and the engaging portions of both are sealed with adhesive. There is.

However, it is best for this type of stop sign board to be carried in all cars at all times, and for this purpose, it is required that it be provided at a low cost so as not to be a burden to the driver, and it must be provided in a short time with fewer manufacturing steps. It is necessary to

Furthermore, since the stop sign board uses reflected light to notify other vehicles of danger, it is necessary to reliably prevent the reflection efficiency of the reflector from decreasing.

In addition, this type of stop sign board is purchased once and kept in the car, and is carried for many years, and is taken out and used in the event of an unexpected accident. It must be removed, assembled, and installed at the same time.

However, the former type of ultrasonic bonding requires high equipment costs, and the latter type of ultrasonic bonding described above has the risk of peeling off over a long period of time due to insufficient adhesive strength.
There is a risk of water intrusion due to poor adhesion, etc., and it takes time to hold down the reflector until the adhesion is complete, and if the frame cracks, water and dirt can easily enter the empty space. However, the reflection efficiency of the reflective surface was reduced.

In view of these points, the present invention is simple and inexpensive to manufacture, and also reliably prevents water and dust from entering the chamber, thereby reducing the risk of low -F reflection efficiency of the reflector. The purpose is to provide lost stop sign boards.

The embodiments shown in the drawings will be described below.

A warning reflector B, which is a heptagonal combination of reflection plates 3A, is erected on the base plate 12, and the warning reflector B and the base plate 12 are foldable.

The reflector A consists of three frames 1, a reflector 2 which is fixed by being forcibly fitted into the frame 1, and an intervening tape inserted between the reflector 2 and the frame 1. It has become.

The frame body 1 has a groove 4 into which the reflective plate 2 is inserted.The upper ends of the edge plates 5a, 51) on both sides of the groove 4 are bent inward so as to face each other, so that they form flanges 6a, 6.
b is formed.

The frame body 1 is made of a resilient material such as polypropylene, polyethylene, ABS, etc., and the edge plates 5a and 5b are
It has enough elasticity to forcibly fit the reflecting plate 2 into the groove 4.

The reflective plate 2 is made of resin or the like, and has a smooth surface and a reflective surface 2a having a sawtooth cross section on the back surface, and light rays incident from the smooth surface are retroreflected by the reflective surface 2a.

Leg portions 7a and 7'b are provided protruding from the peripheral edge of the back surface of the reflecting plate 2, and step portions 8a and 8b are formed at the shoulders on the front side of the reflecting plate 2.

The flange portion 6 a of the frame 1 is attached to the stepped portions 8 a and 8'b.
, 6b are locked.

The interposed tape 3 sandwiched between the frame 1 and the reflection plate 2 is made of sponge, and at least one surface is formed as an adhesive surface.

The reflector A is constructed by laying an intervening tape 3 on the bottom plate 9-L in the groove 4 of the frame 1, and inserting the reflecting plate 2 into the edge plates 5a and 5b while sandwiching the intervening tape 3. Forcibly mate with
The intervening tape 3 and the legs 7a and 7b of the reflector 2 are tightly adhered, and the step 8a, which is the shoulder on the front side of the reflector 2,
, 8b, the flanges 6a and 6b of the frame body 1 are engaged, and press the reflecting plate 2 from above.

The adhesive surface of the intervening tape 3 is directed toward the reflective plate 2 so that the legs 7 a and 7 b of the reflective plate 2 and the intervening tape 3 are adhered to each other.

Note that 11 is a reflective tape attached to the extension plate 1aL of the frame 1.

It goes without saying that the intervening tape 3 may be adhered (7) to the reflecting plate 2 and then forcefully fitted into the groove of the head/body 1.

As explained above, the present invention allows the reflector to be inserted between the reflector, the frame, and the entire surface between the reflector and the frame.
In other words, the reflective plate has a smooth surface, a reflective surface on the back surface, and legs protruding from the periphery of the back surface.
The frame has a groove, and the upper end of the edge plate of the groove is bent inward to form a flange, and the edge plate has enough elasticity to forcibly fit the reflective plate into the groove. The insertion tape is made of resin or ponge and at least one surface is formed with an adhesive surface, and the reflection plate is forcibly fitted into the groove of the frame body by sandwiching the insertion tape, and The structure is such that the flange of the frame is locked to the shoulder on the front side of the reflector, and at least the adhesive surface of the intervening tape is on the opposite side, making it easy to manufacture. Therefore, it is possible to provide an inexpensive stop sign board, and it also reliably prevents water and dust from entering the empty chamber, which causes a low reflection efficiency of the reflector.

In other words, the frame and the reflector can be assembled by simply forcing the reflector into the groove of the frame via the intervening tape.
A reflector can be attached to a frame in a short time and reliably.

Moreover, since the intervening tape is inserted and fitted, and the intervening tape is made of sponge, and the flange of the frame is locked to the shoulder on the front side of the reflector, the reflector It is tightly attached due to the elasticity of the sponge and the pressing force of the flange.

Furthermore, at least one surface of the intervening tape is an adhesive surface, and the reflective plate is forcibly fitted into the frame with this adhesive surface on the reflective surface side, so that the reflective plate is tightly attached to the intervening tape, and the reflective plate and intervening There is no risk of creating gaps between the inserted tapes.

Furthermore, even if a crack occurs in the frame, there is a space formed by the intervening tape and reflective plate, so water, dust, etc. will not get into this space, and it can be carried in the car for a long time. It has great practical effects as a portable stop sign board, as there is no risk of reduction in reflection efficiency even if it is handled roughly in an emergency.
