By the way, referring to the buckle of Patent Document 1, when FIG. 7 of Patent Document 1 is examined closely, the male member provided at the tip of one string becomes the female member provided at the tip of the other string. It has a buckle structure that fits in.
Therefore, when the buckle is fitted, the base end portion of the male member is in a state of being perfectly contacted (contacted by the surface) with the base end portion (tongue piece) of the female member. At this time, although it is rare, a situation in which the user has skin or the like sandwiched between the base end portion of the male member and the base end portion of the female member causes a great inconvenience.

The present invention has been made in view of the above-mentioned problems, and is provided with a buckle that can avoid inconveniences such as pinching the user's skin when the helmet is worn on the user's head. The purpose is to provide a helmet.

In order to solve the above problems, the present invention takes the following technical measures.
That is, the helmet of the present invention includes a cap body that covers the user's head, a right string body and a left string body that extend downward from the cap body and are wound under the user's jaw, and the right string body. A helmet provided with a buckle for connecting the left string body, and the buckle is a right locking body provided on the tip side of the right string body and a left engagement body provided on the tip side of the left string body. The buckle has a stop body, and the buckle has a foreign matter sandwiching portion that may pinch a foreign matter when the right locking body and the left locking body are connected to each other, and the right locking body is present. One of the body and the left locking body is provided with a protective piece provided with an eaves portion that covers the foreign matter sandwiching portion.

Preferably, the buckle has a lower locking body as a right locking body, an upper locking body as a left locking body, and the bottom surface of the upper locking body is attached to the upper surface of the lower locking body. Therefore, it is preferable that the right string body and the left string body are connected to each other.
Preferably, the right string body is connected to the base end side of the lower locking body, the left string body is connected to the base end side of the upper locking body, and the eaves portion is from the tip of the upper locking body. It is preferable that it is formed on the upper surface of the upper locking body so as to overhang.

According to the helmet of the present invention, when the helmet is attached to the user's head and the buckle is fastened, the inconvenience of pinching the user's skin or the like can be avoided as much as possible, and the helmet is prepared. It is possible to reliably wind the chin strap under the user's chin.

It is a perspective view which shows the appearance of the helmet of this invention. It is the figure which looked at the buckle of the helmet of this invention from the side. It is the figure which looked at the buckle of the helmet of this invention from diagonally above. It is an exploded perspective view of the helmet of this invention (the same perspective as FIG. 3).

Hereinafter, an embodiment of the helmet 1 according to the present invention, particularly the buckle 2 provided on the tip end side of the chin strap 6, will be described in detail with reference to the drawings.
It should be noted that the embodiments described below are examples that embody the present invention, and the specific examples do not limit the configuration of the present invention. In this embodiment, a bicycle helmet 1 is illustrated. Further, the front-back direction, the left-right direction, and the up-down direction of the helmet 1 will be described in the directions shown in FIG. This coincides with the direction seen by the user wearing the helmet 1. Similarly, the front-back direction, the left-right direction, and the up-down direction of the buckle 2 will be described in the directions shown in FIG. This coincides with the direction seen by the user wearing the helmet 1.

As shown in FIG. 1, the helmet 1 of the present invention has a size that allows the head to be worn without slippage. Specifically, the helmet 1 of the present invention has a cap body 3 that covers and protects the head, and a shock absorbing member 4 that is attached to the inside of the cap body 3 and absorbs an external impact to protect the head. And a jaw cord 6 for stably wearing a cap body 3 (helmet 1) to which a shock absorbing member 4 is attached on the head by hanging it on the jaw of the head and tightening it.

The cap body 3 is a bowl-shaped housing slightly larger than the size of the head, and is a member that covers at least the frontal region and the occipital region. That is, the cap body 3 is formed of a material that covers and protects the head. The cap body 3 of the present embodiment is a hard housing called a hard shell. For example, the cap body 3 may be made of plastic such as ABS resin. A hole 5 is provided at the top of the cap body 3. The hole 5 releases heat from the head to the outside to improve ventilation and prevent internal stuffiness.

The base end side of the chin strap 6 is attached to the inner wall surface of the cap body 3.
The shock absorbing member 4 is fixed in the cap body 3 without slippage. The shock absorbing member 4 is a member having a size capable of covering the head without slippage. The inner surface of the shock absorbing member 4 is covered with a cloth material because the head comes into contact with the inner surface. The shock absorbing member 4 is made of a material that absorbs an external shock and protects the head. The shock absorbing member 4 is often formed of, for example, Styrofoam.

For example, when the shock absorbing member 4 falls while traveling on a bicycle and an impact is applied to the cap body 3 from the outside (for example, the road surface), the shock absorbing member 4 is deformed to absorb the shock and protect the head. The head is surely protected by the shock absorbing member 4 and the cap body 3.
The chin strap 6 (string body) is a member that stably wears the cap body 3 (helmet 1) provided with the shock absorbing member 4 on the head by hanging it on the chin and tightening it. That is, it can be said that the chin strap 6 is a member that prevents the helmet 1 from falling off from the user's head by hanging it on the chin when worn.

The chin strap 6 is made of a flexible material for hanging on the chin. The chin strap 6 is often formed of, for example, a flat cord body in which a resin thread is woven into a band shape. Four chin straps 6 are attached to the inner wall surface of the cap body 3 in a hanging state (two on each of the left and right sides).
Specifically, the chin strap 6 is attached to the inner wall surface of the cap body 3 on the right front side and the right rear side, respectively, in a suspended state. The right front side jaw strap 6a and the right rear side jaw strap 6b are put together, and one side of the buckle 2 (fastener) (lower locking body 11, in other words, lower engaging body) is attached to the tip thereof. It is attached.

Further, the chin strap 6 is attached to each of the left front side and the left rear side of the inner wall surface of the cap body 3 in a hanging state. The left front side jaw strap 6c and the left rear side jaw strap 6d are put together, and the other side of the buckle 2 (upper locking body 10, in other words, upper engaging body) is attached to the tip thereof. ..
The buckle 27 is provided with a length adjusting mechanism capable of adjusting the length of the chin strap 6. Since the size of the head varies depending on the individual, the length adjusting mechanism adjusts the length of the chin strap 6 so as to fit the user's head.

When the user wears the helmet 1, he covers the head by covering the cap body 3 provided with the shock absorbing member 4. The chin strap 6 is suspended on the left and right sides of the user's head. Of the four jaw cords 6, the cords 6a and 6b extending from the right side are connected by the intermediate coupling 7, and the right cord 6e extending below the user's jaw extends from the lower end side of the intermediate coupling 7. There is. Similarly, of the four jaw cords 6, the cords 6c and 6d extending from the left side are connected by the intermediate coupling 7, and the left cord 6f extending from the lower end side of the intermediate coupling 7 below the user's jaw extends. It is supposed to be done.

A buckle 2 for connecting both string bodies 6e and 6f is provided at the tip of the right string body 6e and the left string body 6f. By connecting the buckle 2 under the chin of the user, the chin strap 6 is wound around the chin, and the helmet 1 is stably worn on the head of the user. The term "submandibular" as used herein refers not only to a portion directly below the jaw but also to a wide area including the lateral side of the jaw.

By the way, the helmet 1 of the present invention is characterized by the structure of the buckle 2.
The buckle 2 of the present embodiment includes an upper locking body 10 (left locking body) and a lower locking body 11 (right locking body), and when both 10 and 11 are engaged with each other, the right string body 6e And the left string body 6f are connected.
First, the lower locking body 11 is a part of the buckle 2 attached to the tip of the right string body 6e, and has a substantially rectangular parallelepiped shape having a length of 4 cm, a width of 2 cm, and a thickness of about 1 cm. It is a thing. A through hole 12 is formed on one side (base end side) of the lower locking body 11 in the length direction, and the right string body 6e passes through the through hole 12 so as to wind around the through hole 12, so that the right string body 6e The lower locking body 11 is attached to the tip of the.

As shown in FIGS. 3 and 4, the upper surface of the lower locking body 11 is a flat surface, and recesses 13 are formed at two locations, one on the center side of the flat surface and the other near the base end. .. The convex portion 14 of the upper locking body 10, which will be described later, is fitted into the concave portion 13, and the locking claw 15 formed at the tip portion of the convex portion 14 of the upper locking body 10 is formed at the inner portion of the concave portion 13. By being caught, the convex portion 14 does not come off from the concave portion 13.

On the other side (tip side) of the lower locking body 11 in the length direction, the convex portion 14 described above is pushed and moved in the horizontal direction by pushing horizontally toward the base end side of the lower locking body 11. , A release piece 16 for releasing the engaged state by the locking claw 15 is provided. The release piece 16 is always urged to the tip side (outside) by the urging force of the spring, and the release piece 16 is pushed back in the horizontal direction with a constant force, in other words, the release piece 16 is locked downward. By pushing it into the body 11, the locked state of the convex portion 14 with respect to the concave portion 13 can be released.

On the other hand, as shown in FIGS. 3 and 4, the upper locking body 10 is a part of the buckle 2 attached to the tip of the left string body 6f, and has a length of 3 cm, a width of 2 cm, and a thickness of about 0.5 cm. It has a substantially rectangular parallelepiped shape of the size of. A through hole 12 is formed on one side (base end side) of the upper locking body 10 in the length direction, and the left string body 6f passes through the through hole 12 so as to wind around the through hole 12, so that the left string body 6f The upper locking body 10 is attached to the tip of the above.

The bottom surface of the upper locking body 10 is a flat surface, and convex portions 14 are formed on the central side and the tip side of the flat surface, respectively. The convex portion 14 formed on the central side is substantially rectangular when viewed from above, and a locking claw 15 projecting horizontally and in the proximal direction is formed on the top of the convex portion 14. The convex portion 14 formed on the tip end side of the bottom surface of the upper locking body 10 has a substantially crescent shape when viewed from below, and follows the R shape of the tip end of the lower locking body 11. A locking claw 15 projecting horizontally and in the proximal direction is also formed on the top of the convex portion 14.

The overhanging direction of the locking claw 15 is the direction in which the left string body 6f exists, in other words, the direction toward the base end side of the lower locking body 11. By catching the locking claw 15 at the inner portion of the concave portion 13, the convex portion 14 does not come off from the concave portion 13.
Further, magnets are embedded in the upper locking body 10 and the lower locking body 11, respectively, and when both locking bodies are brought close to each other, they are naturally attracted by magnetic force, and the upper surface of the lower locking body 11 is the upper locking body. 10
The convex portion 14 of the upper locking body 10 is fitted into the concave portion 13 of the lower locking body 11 so that the two are not disengaged by the locking claw 15 and are engaged with each other. ..

To release this state, the release piece 16 provided on the lower locking body 11 is pushed into the lower locking body 11 to push the convex portion 14 of the upper locking body 10 into the base end of the lower locking body 11. It is preferable to push it toward the side, in other words, to release the engaged state by the locking claw 15 by sliding the bottom surface of the upper locking body 10 along the upper surface of the lower locking body 11.
According to the buckle 2 having such a configuration, when locking is performed, the upper locking body 10 and the lower locking body 11 are smoothly contacted by the force of the magnet, and the right string body 6e and the left The string body 6f can be easily connected. On the other hand, by pushing in the release piece 16 provided on the lower locking body 11, the coupling state of the upper locking body 10 by the locking claw 15 can be easily removed, so that a woman with weak force or Even a child can easily release the connection state of the string body 6 by the buckle 2.

As described above, the buckle 2 of the present embodiment has many advantages, but there are some inconveniences.
As shown in FIG. 2, when the buckle 2 is engaged, the bottom surface of the upper locking body 10 and the upper surface of the lower locking body 11 come into close contact with each other. If, for example, the skin of the user's jaw is caught in this part, the user will feel pain (the part shown by the broken line in FIG. 2). That is, when the upper locking body 10 and the lower locking body 11 are vertically overlapped with each other, there is a foreign matter sandwiching portion that may pinch the foreign matter. In particular, when the upper locking body 10 and the lower locking body 11 are brought close to each other by the force of a magnet and integrated, the possibility of pinching the skin by the foreign matter sandwiching portion increases.

Although such inconvenience does not usually occur, it cannot be said that pinching does not occur by any chance when used by a beginner or a child who is not accustomed to handling the buckle 2.
Therefore, the buckle 2 of the present embodiment is provided with a protective piece 20 for avoiding such inconvenience.
The protective piece 20 is a plate-shaped member and has a shape that covers the upper surface of the upper locking body 10. The only difference is that, as shown in FIG. 2, the protective piece 20 is further extended at the tip of the upper locking body 10, for example, it is like a roof eaves. (Eaves 21). The eaves portion 21 comes into contact with the skin under the chin of the user when the buckle 2 is fastened.

The eaves portion 21 has an arc shape when viewed from above, and projects slightly downward (closer to the lower locking body 11) from the tip portion of the upper locking body 10 by about 5 to 10 mm. The tip of the eaves portion 21 is in contact with or close to the right string body 6e to which the lower locking body 11 is attached when the buckle 2 is engaged.
With such an eaves portion 21, the upper surface of the lower locking body 11 is in contact with the bottom surface of the upper locking body 10, and the tip of the upper locking body 10 is a cliff-shaped portion, in other words, the user. It is designed to cover areas that may pinch unexpected foreign substances such as the skin of the eaves. The eaves portion 21 prevents the user's skin from reaching the portion where the upper locking body 10 and the lower locking body 11 come into contact with each other.

With the protective piece 20 having such a structure, it is possible to avoid as much as possible the inconvenience caused by the pinching of foreign matter in the buckle 2.
Looking at FIG. 3 and the like, the upper locking body 10 and the protective piece 20 are formed as separate bodies, and both are assembled, but the eaves portion 21 is attached to the tip of the upper locking body 10. May be integrally formed.

The usage mode of the helmet 1 described above is no different from that of the normal helmet 1.
First, the user wears the cap body 3 on the head, turns the right string body 6e from the right side of the face to the bottom of the chin, and turns the left string body 6f from the left side of the face to the bottom of the chin, and under the chin, The buckle 2 is fastened, that is, the upper locking body 10 and the lower locking body 11 are aligned in the vertical direction. Then, the convex portion 14 of the upper locking body 10 is fitted into the concave portion 13 of the lower locking body 11, and the locking claw 15 is caught in the back of the concave portion 13, so that the upper locking body 10 and the lower locking body 10 are locked. The body 11 is integrated, and the buckle 2 is in an engaged state.

At this time, the bottom surface of the upper locking body 10 and the upper surface of the lower locking body 11 come into close contact (interview) with each other, and the eaves portion 21 of the protective piece 20 is attached to the upper locking body 10. In order to prevent the user's skin from reaching the interviewed portion (the portion shown by the solid line in FIG. 2), it is possible to avoid an inconvenient situation such as pinching of a foreign substance.
In order to release the buckle 2 after use, the release piece 16 provided on the lower locking body 11 is pushed into the lower locking body 11 to lower the convex portion 14 of the upper locking body 10. By pushing toward the base end side of the body 11, the engaged state by the locking claw 15 can be released.

According to the structure of the helmet 1 described above, particularly the buckle 2, when the helmet 1 is attached to the user's head and the buckle 2 is fastened, the inconvenience of pinching the user's skin or the like is possible. It is possible to avoid the problem and to surely wind the buckle 6 provided on the helmet 1 under the user's jaw.
It should be noted that the embodiments disclosed this time are exemplary in all respects and are not restrictive.

That is, since the feature of the present invention lies in the protective piece 20, particularly the eaves portion 21, there are no major restrictions on the structure and locking method of the upper locking body 10 and the lower locking body 11. A buckle 2 having an eaves portion 21 that covers a portion where sandwiching between the upper locking body 10 and the lower locking body 11 is likely to occur, or a protective piece 20 having the eaves portion 21 belongs to the category of the present invention. ..
