Description

Detailed Description of the Invention A. Purpose of the Invention (1) Field of Industrial Use The present invention has a cap body covering a wearer's head, which comprises a shell and a shock absorbing liner joined to the inner surface of the shell. A full-face type helmet in which the ends of the left and right jaw cords are connected to each other, and the middle portions of the jaw cords are held by the left and right jaw cord holders that are respectively connected to the left and right sides of the cap body. Regarding

(2) Conventional technology Conventionally, the jaw strap holder of such a helmet has a soft skin,
It was generally formed of cloth or a synthetic resin having high flexibility (see, for example, Japanese Utility Model Laid-Open No. 62-110235).

(3) Problems to be Solved by the Invention In the conventional device, the left and right jaw cord holders cannot be appropriately brought into close contact with the wearer's cheeks by their own elastic force before the jaw cords are tied, that is, , It is not possible to urge each jaw strap holder inwardly to make it stick to the cheeks by first tensioning and tying the left and right jaw straps together. If the knot becomes loose after the tying, it is not possible to fit the chin strap holder to the cheeks accurately, and there is the inconvenience that the ability to hold the cap on the head is greatly reduced. . In order to eliminate such an inconvenience, when the jaw cord holder is simply given an elastic force that biases the lower half of the jaw inward, the lower half of the jaw tightly hits the wearer's cheek. There is a risk that the feeling of wearing may be impaired.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a full-face type helmet that can solve all of the above problems and that can also perform the work of tying the chin strap efficiently.

B. Configuration of the Invention (1) Means for Solving the Problems According to the present invention in order to achieve the above object, according to the present invention, a cap body covering a wearer's head is provided with a shell and an impact absorbing liner joined to the inner surface of the shell. The left and right sides of the cap body are connected to the ends of the left and right jaw cords respectively, and the middle portion of the jaw cords is connected to the left and right jaw cord holders connected to the left and right sides of the cap body, respectively. In the full-face type helmet that is configured to be retained, each jaw strap holder includes a support portion connected to the cap body, and an abutment portion that is connected to the lower end of the support portion and the middle portion of the jaw strap vertically penetrates. A pad made of a flexible material for contacting the wearer's cheeks is provided at the inner end of the abutting portion, and the abutting portion is free of the pad. In the state, the pad is placed inside the cap rather than the inner peripheral surface of the shock absorbing liner. Inward from the lower end of the support part so that the pad is elastically pressed against the wearer's cheek by elastic deformation of the contact part when the wearer's head is covered with the cap body. It is formed in a substantially L-shaped bent shape.

(2) Action Regardless of whether or not the left and right jaw straps are tied and placed in a tension state when the cap body is covered, the contact portions of the left and right jaw strap holders are elastically exerted by the elastic force of the wearer's cheeks. Since it can be positively abutted against the chin strap, even if the chin strap is loosely tied afterwards, or even if the tie is tightly tied and the knot later loosens, Since the contact portion can be always brought into close contact with the cheek, the holding property of the cap body on the wearer's head is not significantly reduced. Moreover, since the contact portions of the left and right jaw strap holders can be brought into close contact with the wearer's cheeks just before the chin straps are tied by simply covering the cap body, both contact portions are vertically penetrated. The left and right chin straps can be brought as close as possible to each other, and the chin straps can be tied quickly and easily.

In addition, in particular, since a flexible pad is interposed between the contact part of each jaw cord holder and the cheek of the wearer, the fitting feeling is good despite elastically urging the contact part to the cheek side. Is.

On the other hand, the front portion of the cap body 1 is provided with introduction holes 35 corresponding to the upper air intake holes 33, and each introduction hole 35 has a connection pipe 36 projecting coaxially with the projection 34. Are respectively fitted. Therefore, the air taken in through the upper air intake hole 33 is introduced into the cap body 1 through the connecting pipe 36 and the introduction hole 35.

By the way, since the ventilation gap 25 formed between the guide plate 26 and the shell upper body 2a is opened at the upper end thereof through the air exhaust port 32, the ventilation gap 25 is opened from the air exhaust port 32.
Rainwater may flow in. Therefore, the ventilation gap 25 is formed in the edge member 17 at a portion corresponding to the upper edge of the opening 7.
In order to receive the rainwater that has invaded inside, there is provided a trough portion 48 that is formed in a substantially U-shape with the upper portion opened slightly and outwardly beyond the shell upper body 2a, and the rainwater is guided by the trough portion 48. This prevents the rainwater from entering the cap body 1 through the openings 7 and dropping downward from both sides of the openings 7.

The guide plate 26 has a pair of elongated holes 37 extending vertically above the upper air intake holes 33, and an elongated hole 38 extending vertically at the center between the elongated holes 37. An opening / closing plate 41 integrally including a pair of guide plate portions 39 fitted in the long holes 37 and a guide plate portion 40 fitted in the long holes 38.

Moreover, the engaging portion 42 is provided with ridges 42a and 42b at its upper and lower portions in order to hold the state where the opening / closing plate 41 is in the open position and the closed position by utilizing the elasticity of the guide plate portion 39. And the engaging pin 43 has the ridges 42a and 42b.
The open position and the closed position of the opening / closing plate 41 are maintained by getting over the vehicle.

In FIG. 10, one end of a chin strap 44 is fixed to the inner surfaces of both sides of the cap body 1, and chin strap holders 45 holding the chin straps 44 are fixed to the inner surfaces of both sides of the shell 2. The chin strap holder 45 is integrally formed of an elastic synthetic resin, is formed in a flat plate shape along the inner surface of the shell 2, and has an upper portion fixed to the inner surface of the shell 2 by a pin 46. And its support 45
It is formed in a substantially L shape by a contact portion 45b bent inward from the lower end of a, and the inner end of the contact portion 45b is flexible so as to elastically contact the cheek of the wearer. A pad 47 made of urethane foam is fixed. The contact portion 45b is in its free state (see the solid line position in FIG. 10).
Then, when the pad 47 is projected inward from the inner peripheral surface of the shock absorbing liner 3 and the head of the wearer is covered with the cap body 1 (see the position of the chain double-dashed line in FIG. 10). Contact part 45b
A substantially L-shaped bent shape from the lower end of the support portion 45a to the inner side is determined so that the pad 47 is elastically pressed against the wearer's cheek by its own elastic deformation. Again chin strap 4
4 is engaged with the intermediate portion of the support portion 45a and abuts on the contact portion 45b.
And penetrates up and down, and is drawn outward from the outer surface of the contact portion 45b.

Next, the operation of this embodiment will be described. Since the shell 2 that constitutes the cap body 1 together with the shock absorbing liner 3 is divided into the shell upper body 2a and the shell lower body 2b,
By combining the shell upper body 2a and the shell lower body 2b, which are individually molded, the shell 2 with a narrower bottom can be configured, and the mold configuration can be simplified to facilitate manufacturing. Moreover, since the lower air intake hole 11 and the exhaust hole 22 are provided in the shell lower body 2b, the mold structure can be simplified as compared with the case where the shell is integrally molded, which also facilitates the manufacturing.

Further, when the cap body 1 is put on, the contact portions 45b of the left and right jaw cord holders 45 are pushed open to the wearer's cheeks via the pads 47 and elastically deformed as shown by the two-dot chain line in FIG. Therefore, the contact portions 45b of the left and right jaw cord holders 45 can be positively brought into contact with the wearer's cheeks regardless of whether or not the left and right jaw cords 44 are tied and placed in a tension state. ,afterwards,
Even if the chin strap 44 is loosely tied, or if the knot is tightly tied and the knot later loosens,
The contact part 45b of the chin strap holder 45 can be always brought into close contact with the cheek. Moreover, since the contact portions 45b of the left and right jaw cord holders 45 can be positively brought into close contact with the wearer's cheeks before the left and right jaw cords 44 are connected, both contact portions 45b are vertically penetrated. The left and right chin straps 44 can be brought as close as possible to each other, and the chin straps 44 can be tied quickly and easily.

In addition, in particular, since the flexible pad 47 is interposed between the contact portion 45b of each jaw cord holder 45 and the cheek of the wearer, despite elastically biasing the contact portion 45b toward the cheek, The contact portion 45b can be softly applied to the cheek via the pad 47.

Assuming that a motorcycle or the like is to be equipped with such a full-face type helmet, the exhaust port 3 will be generated by the traveling wind.
Negative pressure is generated in the ventilation gap 25 by the air drawn out from the air gap 2. The negative pressure causes the air guided to the inner surface of the shield plate 8 to flow from the gap 31 into the ventilation gap 25, and then to the outside from the exhaust port 32. Is discharged. Therefore, the shield plate 8
Inside, the hot air and moisture are sucked into the ventilation gap 25 to rise, and are discharged from the air outlet 32, so that ventilation is effectively performed. Further, when the lower air intake hole 11 is open, the air introduced into the passage 14 from the lower air intake hole 11 is guided to the inner surface of the shield plate 8 through the circulation hole 20, so that the air of the shield plate 8 is introduced. Rising along the inner surface,
The shield plate 8 is effectively prevented from being fogged. Moreover, the exhalation of the wearer is prevented by the exhalation guide member 15 from the shield plate 8
Since it is blocked from hitting directly to the shield plate 8
The anti-fog of can be achieved more reliably.

Although rainwater inevitably intrudes into the ventilation gap 25 from the exhaust port 32 when traveling in the rain, the invading rainwater is received by the gutter portion 48 of the edge member 17 at the lower end of the ventilation gap 25, and is guided by the gutter portion 48. While being guided, it rotates around the outer periphery of the opening 7 and falls downward, so that it is possible to reliably prevent rainwater from entering the hat body 1 through the opening 7.

Further, the air introduced into the cap body 1 through the upper air intake hole 33 and the introduction hole 35 flows through the passage groove 23 and the cap body 1
It circulates to the inner rear portion and is discharged to the outside from the exhaust hole 22 through the passage hole 24, so that the inside of the cap body 1 is sufficiently ventilated.

C. As described above, according to the present invention, when the cap body is covered, the abutting portions of the left and right jaw cord holders can be moved regardless of whether the left and right jaw cords are tied and placed in a tension state. Since it can positively contact the wearer's cheeks with its own elastic force, if the chin strap is loosely tied, or if the knot is tightly tied and the knot later loosens. However, the contact portion of the chin strap holder can always be brought into close contact with the cheeks at all times, and there is no fear that the retention of the cap body on the wearer's head will be significantly reduced. Moreover, by simply wearing the cap body, the contact portions of the left and right jaw strap holders can be positively brought into close contact with the wearer's cheeks even before the left and right jaw straps are tied, so that both contact portions are It is possible to bring the left and right chin straps, which vertically penetrate through each other, as close as possible to each other, and thus contribute to improving the efficiency of the work of tying the chin straps.

Furthermore, when the contact part of each chin strap holder is brought into close contact with the wearer's cheek, a soft pad is interposed between the contact parts, so even if the contact part is elastically biased toward the cheek, the feeling of wearing is improved. There is no risk of damage, and the contact area can be softly applied to the cheek through the pad.
