Description

Detailed Description of the Invention A0 Object of the Invention (1) Industrial Application Field The present invention provides a cap that covers the wearer's head, and a cap that can be opened and closed by a shield plate supported on the front part of the cap that covers the wearer's head. The present invention relates to a helmet provided with an opening.

(2) Prior Art Conventionally, when such a helmet is used with the opening closed by a shield plate, the inner surface of the shield plate may become cloudy due to the exhalation of the wearer, which may impair visibility. In order to eliminate such inconveniences, for example, full-face helmets have already been proposed in which an exhalation guiding member is attached to the cap body to prevent the wearer's exhaled air from flowing toward the opening. Publication No. 59-103719).

(3) Problems to be Solved by the Invention However, hot air and moisture tend to accumulate inside the shield plate, so it is only necessary to avoid the wearer's exhaled air from flowing toward the shield plate as in the above conventional method. However, it is not possible to reliably eliminate fogging of the shield plate. Therefore, the present applicant fixed a guide plate to the cap body above the opening, which forms a ventilation gap between the cap body and the inside of the shield plate, and fixed the guide plate to the cap body below the opening. A full-face helmet with air intake holes on the body has already been proposed (Jikken Sho 61-
124398), which draws and discharges air from the top of the guide plate and the exhaust port formed between the helmet body and the inside of the shield plate when the helmet is worn. This allows fresh air to circulate in both directions to prevent the shield plate from fogging up.

By the way, when wearing a helmet, it would be convenient if the air between the wearer's head and the cap body could be efficiently ventilated. Ventilation between the spaces may also be possible.

The present invention was developed in view of the above circumstances, and provides a full-face helmet that utilizes the air attraction effect of the guiding plate to efficiently ventilate the space between the wearer's head and the cap body. The purpose is to provide.

B1 Structure of the Invention (1) Means for Solving the Problems The present invention provides a method for forming a ventilation gap in the front part of the cap body above the opening and communicating with the cap body inside the shield plate.

It is held by the frictional force between the joint arm 45 and both side edges of the exhaust port 42.

Next, to explain the operation of this embodiment, assuming that this full-face helmet is worn while traveling on a motorcycle or the like, the opening/closing plate 4 as shown in FIG. 7(a)
3 is opened to open the exhaust ports 41.42, and when the shirt cover plate 34 is closed, the exhaust ports 41.4 are opened by the running wind.
Negative pressure is generated in the ventilation gap 27 by the air led out from the ventilation hole 31, and the air guided inside the shield plate 9 by the negative pressure flows into the ventilation gap 27 from the ventilation hole 31. is discharged to the outside. Moreover, the air inside the cap body 1 is drawn to the ventilation gap 27 through the circulation hole 36 by the negative pressure in the ventilation gap 27, and this air is also drawn and discharged from the ventilation gap 27 to the outside through the exhaust ports 41 and 42.

Therefore, hot air and moisture are sucked inside the shield plate 9, rise, and are discharged from the exhaust ports 41 and 42, and hot air and moisture between the cap body 1 and the wearer's head are also discharged. , ventilation is performed effectively. Further, when the air intake hole 14 is open, fresh air is guided inside the shield plate 9, so that the shield plate 9 is effectively prevented from fogging. Moreover, since the wearer's breath is prevented from directly hitting the shield plate 9 by the breath guiding member 21, the shield plate 9 can be prevented from fogging more reliably.

Furthermore, since the exhalation guide member 21 has a guide hole 24 and is fitted to the upper end of the passage 20, fresh air can flow inside the shield plate 9 while ensuring the circulation area of the passage 20. can be reliably supplied.

Next, as shown in FIG. 7(b), when the introduction hole 32 is opened with the opening/closing plate 43 in the open position, the fresh air introduced from the introduction hole 32 passes through the circulation hole 36. It is introduced into the cap body 1, flows between the wearer's head and the cap body 1, and is led out from the exhaust hole 25, so that ventilation between the wearer's head and the cap body 1 can be performed. can. Moreover, at this time, there is still an air flow toward the upper blade in the ventilation gap 27, and the air that has risen inside the shield plate 9 is discharged from the exhaust port 4142 through the ventilation gap 27.

By the way, with the air exhaust ports 41, 42 open in this manner, it is inevitable that rainwater will enter into the ventilation gap 27 when the vehicle is running in the rain. However, since the -F end of the edge member 19 is provided with the mallet part 38, the rainwater that has entered is received by the mallet part 38 and flows to both sides of the opening 8. Therefore, it is possible to reliably prevent rainwater from entering the cap body 1 through the opening 8. Moreover, since the hammer part 38 is provided above the ventilation hole 31, it is possible to avoid the hammer part 38 from affecting the circulation area of the ventilation hole 31, and to ensure a sufficient circulation area of the ventilation hole 31. can. Also, ventilation hole 3
1 on the edge member 19, it is possible to prevent the ventilation hole 31 from collapsing, and this also ensures a sufficient circulation area of the ventilation hole 31 to ensure sufficient ventilation air at all times. can do.

In order to prevent air from flowing inside the shield plate 9 during cold weather, the muco opening/closing plate 4 should be closed as shown in FIG. 7(C).
3, and then the exhaust port 4142 is closed, so that no negative pressure is generated in the ventilation gap 27, and therefore no air flows inside the shield plate 9.

In addition, when ventilation is performed between the wearer's head and the cap body l with the opening/closing plate 43 closed, as shown in FIG. 7(d).
As shown in , it is sufficient to open the introduction hole 32 with the shirt cover plate 34, and then the fresh air introduced through the introduction hole 32 will be introduced into the cap body 1 through the circulation hole 36, so that the head of the wearer will not be affected. Also, sufficient ventilation can be achieved between the cap bodies 1.

Furthermore, the edge member 18 fitted to the lower edge of the shell 2 includes:
A projecting portion 18a extending inwardly of the cap body 1 is provided at a portion corresponding to the chin cover portion 1a, and the gap between the cap body 1 and the wearer's neck can be minimized by this projecting portion 18a. This makes it possible to minimize noise caused by wind entrainment while driving.

C2 Effects of the Invention As described above, according to the first feature of the present invention, above the opening, the front part of the cap body is provided with a ventilation gap that communicates with the cap body inside the shield plate. A ventilation hole is provided at the top of the guide plate, and a ventilation hole is provided in the cap body above the opening to communicate the inside of the cap body with the ventilation gap. Air circulates along the inner surface of the shield plate to remove fogging, and air is drawn into the ventilation gap from the circulation holes to ensure sufficient ventilation between the wearer's head and the cap body. can.

According to the second feature of the present invention, the guide plate is provided with an introduction hole that can be opened and closed and faces the circulation hole with a ventilation gap in between, so that the introduction hole can be opened when the helmet is being worn.
