Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a collar collar for school uniforms.

[Conventional technology and its problems]

Since school uniforms are generally black or gray, it is difficult for drivers to see students wearing school uniforms in the dark at night or on rainy days. . As a result, the discovery was delayed and there was a risk of personal injury. One possible countermeasure is to attach reflective tape to parts of shoes and clothing, but the former is placed too low and is difficult to see, while the latter requires attaching reflective tape to four locations on the front, back, left, and right of school uniforms, which is a design issue. It is not possible.

The object of the present invention is to provide a collar collar that solves the above problems.

[Means for solving problems]

The present invention forms a notch-like or curved fold in the longitudinal direction parallel to the upper edge with a small distance between it and the upper edge on the inner surface of the neck side of the collar body,
The folded piece portion provided so as to fall outward at the fold portion is substantially tightly covered with a retroreflective film made of soft plastic having a substantially inverted J-shaped cross section, and the reflective film is One side edge is fused to the fold from the outside, and the other side edge is
It is fused to a position below the fold on the inner surface of the neck side.

[Effect]

The folding piece easily deforms elastically outward at the crease in response to neck movements such as bending and turning. By returning the neck to a straight position, the collar body itself and the reflective film material's elasticity immediately restores the original shape.
By attaching a retroreflective film to the upper edge of the collar body, the driver inside the car can see the reflected light from the film from all directions, allowing them to detect people in front of them at an extremely early stage. can be known.

〔Example〕

Embodiments of the present invention will be explained in detail based on the drawings.

In FIGS. 1, 2, and 3, reference numeral 1 denotes a collar collar according to the present invention, which is attached to the inside of the collar body 2 of a school uniform by means of hooks 3. 4 are elongated holes for locking the hooks 3, and are provided at a plurality of locations at appropriate intervals in the longitudinal direction of the collar body 5. 6... are locking metal fittings attached to both ends of the collar main body 2.

Thus, on the inner surface 7 of the collar body 5 on the neck side, a notch-like fold 9 is formed in the longitudinal direction parallel to the upper edge 8 of the collar body 5 with a small distance L between the collar body 5 and the upper edge 8. . Specifically, the fold portion 9 is
With respect to the thickness t of the collar body 5, a cut 11 of a predetermined depth is provided over the entire length of the collar body 5, except for a slight remaining thickness 10. The folded piece 12, which is provided so as to fall outward at the fold 9, is covered in a substantially tight manner with a retroreflective film 13 made of soft plastic and having a substantially inverted J-shaped cross section. . Specifically, there is almost no gap between the upper edge 8 of the collar body 5 and the inner surface of the reflective film 13. Note that the collar body 5 and the reflective film 13 are made of, for example, soft vinyl chloride. In the state where the bent piece portion 12 is covered, one side edge 1 of the reflective film 13
4 are fixed to the inner surface 7 and outer surface 16 of the collar body 5, respectively, so as to be at a higher position than the other side edge 15.
That is, the one side edge 14 of the reflective film 13 is fused from the outer surface 16 of the collar body 5 to the above-mentioned fold 9, and the other side edge 15 is fused from the inner surface 7 on the neck side to a position below the fold 9 by means of high frequency or the like. This is what I wore. 1
7 and 17 indicate the fused portions. The collar body 5 is provided to protrude upward from the upper edge 18 of the collar body 2 by a dimension H of about 3 to 8 mm.

As shown in FIG. 6, the retroreflective film 13 has a large number of tiny prisms on its back surface, which directs the light R emitted from a light source such as a car headlight, that is, incident light, toward the light source. It is possible to bounce back (retroreflection). As a retroreflective film based on such a principle, there is, for example, the trade name "Reflexite" (manufactured by Reflexite Corporation in the United States).

As shown in FIG. 4, when the neck K is tilted in the direction of the arrow A, if the neck K is hit a little forcefully, the bent piece 12 escapes in the outward direction B together with the reflective film 13 covering it. In this state, the cut 11 of the folded portion 9 is slightly expanded, and the remaining flesh portion 10
is deformed. Also, at this time, the reflective film 13 temporarily stretches in its width direction,
Since the fused portion 17 is placed below the cut 11, it is not possible to prevent the cut 11 from widening. Next, by straightening the neck K, the bent piece 12 immediately returns to its original state, but this is mainly due to the elastic force of the material of the reflective film 13. Since the upper edge 8 of the collar body 5 is in close contact with the upper edge 8 of the collar body 5, the elastic force of the reflective film 13 is effectively used for the above-mentioned restoring force of the folded piece 12.

Unlike the case of the above embodiment, the crease portion 9 has shallow small recesses 19, 19 as shown in FIG.
There is no problem in giving a crease by adding a .

7 and 7 show comparative examples, in which only the reflective film 13 is applied to the upper edge 1 of the collar body 2.
8, that is, a bent piece 12
This is the case where no . There is no collar body 5 as a core material inside the reflective film 13, so there is a void 2.
0, it is extremely soft to use, but as shown in Figure 7, it does not return to its original shape and bends or becomes permanently deformed into a flattened shape. It will be put away. Therefore, the visible area on the upper side of the collar main body 2 becomes smaller, which is inconvenient. Furthermore, when covering the reflective film 13, which is a soft material, along the upper edge 8 of the collar body 5, since the reflective film 13 is not in close contact with the upper edge 8, the relative position of the collar body 5 in the width direction may be misaligned. It is extremely difficult and inefficient to do so. Next, as shown in FIG. 8 and FIG.
When the notches 21, 21 are formed only at both ends, the reflective film 13 can be closely attached to the upper edge 8 of the other parts, and when covering the reflective film 13, does not have the drawbacks of the comparative example shown in FIG. Moreover, the notch part 2
1 and 21 have the advantage that when the head is tilted forward, the chin area is soft and comfortable to use. As is clear from the figure, it has the disadvantage of gradually becoming permanently deformed and cannot maintain a stable reflection width over time. Therefore, Figure 1~
The embodiment of FIG. 6 overcomes these drawbacks and incorporates their advantages.

[Effect of idea]

The present invention has the following remarkable practical effects due to the above-described configuration.

Since the retroreflective film 13 is provided around the neck, a car driver or the like can see the reflective film 13 from any direction. From this, light R emitted from car headlights at night etc.
The light reaches the reflective film 13 very easily and reliably returns to the light source. Therefore, it greatly contributes to traffic safety.

The part projecting upward from the collar main body 2 does not get in the way at all even when the neck is moved, so the neck does not get hurt or feel cramped, and a soft feeling of use can be obtained. In addition, it can protrude upward from the collar main body 2 sufficiently in this way, and can reflect the light of the car and draw sufficient attention to the driver.

One side edge 14 of the reflective film 13 is folded into the fold 9
By fusion bonding, the folded portion 9 is reinforced and has the effect of preventing cracks.

Since the other side edge 15 is fused to the lower position of the folded part 9, elastic deformation of the folded part 9 is allowed, especially when the folded part 9 is made into a notch shape, and the soft feeling of use is not impaired. .

Since the reflective film 13 can be easily positioned to cover the reflective film 13, workability in the production process is improved.

The collar body 5 serves as the core of the reflective film 13 and maintains the correct shape. Therefore, the reflective film 1
A part of 3 will not be permanently deformed into a flat shape,
A constant reflection width can be maintained for incident light from the outside.

Since the shape is almost unchanged compared to conventional collar bodies, there are no design problems.
