Description

[Detailed explanation of the invention] A. Purpose of the invention (1) Industrial application field This invention is intended for use with helmets, especially shells, used mainly by operators of motorcycles and competition cars.
The cap body is composed of a buffer liner fitted on the inner surface of the shell, a flexible fit pad is arranged on the inner peripheral surface of the buffer liner, and an air intake is provided on the front wall of the cap body, penetrating the inside and outside of the cap body. This invention relates to an improvement in a helmet in which the inside of the helmet can be ventilated by having a hole bored therein and introducing the running wind generated as the vehicle travels into the helmet through the air intake hole.

(2) Prior Art Conventionally, in such helmets, a highly flexible and continuously porous fit pad is lined with a buffer liner, and the running wind taken into the air intake hole is directed through the multi-porous pores of the fit pad. It is known that the material is distributed and supplied inside the pad (for example, see US Pat. No. 4,054,953).

(3) Problems to be solved by the invention However, in general, fitting pads are formed with a relatively thick wall to allow the user's head to fit into the inner surface of the cap body, so it is difficult to avoid continuous porous structure. However, the ventilation resistance is very high. For this reason, in the above-mentioned conventional helmet, the amount of running wind that reaches the inside of the fit pad is very small, and improvement in ventilation is desired.

The present invention was developed in view of the above circumstances, and has a structure that improves ventilation inside the cap body by ensuring that the running wind taken in through the air intake hole can always be introduced to the inside of the fit pad. An object of the present invention is to provide a helmet that is comfortable to wear.

B. Structure of the invention (1) Means for solving the problem In order to achieve the above object, according to the present invention, the fit pad is attached to the inner peripheral surface of the buffer liner so that ventilation is possible between the fit pad and the inner peripheral surface of the buffer liner. Along with being polymerized,
The lower opening end of the pad is fixed to the cap body so that the upper open end becomes a free end, and the pad is provided with a through hole that passes through the inside and outside of the pad in correspondence with the air intake hole in the front wall of the cap body. The width of the through hole is set to be smaller than the inner diameter of the air intake hole so that a part of the air intake hole is covered by the fit pad, and the cross-sectional area is equal to or larger than that of the air intake hole. The cap body is formed into a long hole extending vertically longer than the inner diameter so as to have a larger diameter, and a ventilation groove is provided in the ceiling surface of the cap body along the extension line of the through hole.

(2) Effect The running wind taken into the air intake hole is introduced into the inside of the fit pad through the through hole without being obstructed by the fit pad. Since the through hole is a long hole extending toward the ventilation groove on the ceiling surface of the cap body, the air exiting the through hole relatively easily flows into the ventilation groove and smoothly circulates within the groove. Furthermore, since the traveling wind can be introduced into the inside of the cap body from the air intake hole through the overlapping surfaces of the fit pad and the inner circumferential surface of the buffer liner, the traveling wind can be dispersed within the cap body. As a result, ventilation within the cap body is extremely efficient as a whole.

In addition, since the upper open end of the fit pad is a free end, the air intake hole and the through hole may be slightly misaligned in the vertical direction due to errors in assembling the fit pad to the buffer liner or misalignment when wearing the helmet. Even if this occurs, the through hole is a long hole that is vertically longer than the inner diameter of the air intake hole, so the through hole and the air intake hole should always face each other precisely regardless of the positional deviation. I can do it.

Furthermore, since the fit pad partially covers the air intake hole, the feeling of depression given to the user of the air intake hole can be effectively alleviated by using the flexible fit pad. Furthermore, even though the air intake hole is partially covered by the fit pad, the through hole is made into a long hole with a cross-sectional area equal to or larger than that of the air intake hole. Therefore, the increase in ventilation resistance can be suppressed as much as possible.

(3) Examples Examples of the present invention will be described below with reference to the drawings.

First of all, starting with the first embodiment, in FIGS. 1 to 5, H is a full-face helmet worn mainly by the operator of a motorcycle or a racing car, that is, the cap body 1 is attached to a front window. A chin cover portion 1a is provided that extends to form the lower edge of the hole 2. A translucent shield plate 3 is attached to the cap body 1 at both ends by pivots 4 so as to open and close the window hole 2 by vertically rotating the shield plate 3.

The cap body 1 consists of a shell 5 and a buffer liner 6 made of foamed polystyrene that is integrally fitted to the inner surface of the shell 5.

The shell 5 is divided into an upper shell body 5A and a lower shell body 5B at the position of the chin cover part 1a, and the overlapping parts of both shells 5A and 5B are held together by rivets 7 at several places with the shell lower body 5B outside. is bound to. The shell upper body 5A is molded from a thermosetting synthetic resin such as fiber-reinforced polyester,
The shell lower body 5B is injection molded from thermoplastic synthetic resin such as ABS. By dividing the shell 5 into upper and lower halves in this way, even if the shell 5 has a shape with a narrowed opening at the bottom, it can be easily manufactured.

A top pad 8 made of flexible urethane foam is adhered to the ceiling surface of the buffer liner 6, and a foot pad 9 made of flexible urethane foam is attached to the inner peripheral surface of the buffer liner 6 other than the ceiling surface.
They are arranged so as to overlap with the inner circumferential surface so as to allow ventilation. On the inside of this fitting pad 9,
A breathable lining 10, for example a pile lining, is attached, and the lower open end of the lining 10 is sandwiched between the shell 5 and the buffer liner 6. Therefore, the upper open end of the fit pad 9 becomes a free end, and the lower open end becomes a fixed end to the cap body 1.

A pair of left and right air intake holes 1 are provided in the front wall of the cap body 1, passing through the shell 5 and the buffer liner 6 directly above the window hole 2.
1 and 11 are bored, and sliding lids 12 and 12 are attached to the shell 5 to open and close the entrances thereof. In addition, the air intake holes 11, 11 are provided in the fit pad 9.
A pair of front through holes 13, 13 are bored at locations corresponding to the above. The air intake hole 11 and the through hole 13 have different cross-sectional shapes (see Fig. 5); the air intake hole 11 is circular, while the front through hole 13 is circular.
is an oval shape that has a hole width that is approximately half the inner diameter of the air intake hole 11 and extends longer than the inner diameter in the vertical direction. In the illustrated example, it covers both the left and right sides. Moreover, the cross-sectional area of the front passage hole 13 is set to be equal to or larger than that of the air intake hole 11.
The inner opening end of the front passage hole 13 is entirely covered with the lining 10.

Further, on the inner surface of the top pad 8, two ventilation grooves 14, 14 are provided which extend along the rearward extension line of the through holes 13, 13, that is, the elongated holes.

Further, on both rear side walls of the cap body 1, a shell 5 is provided.
and a pair of air exhaust holes 1 passing through the buffer liner 6
5, 15 are bored, and these air exhaust holes 15, 1
Rear through hole 1 in fit pad 9 at the corresponding position to 5.
6 and 16 are drilled. The air exhaust hole 15 and the rear passage hole 16 are formed in the same relationship as the air intake hole 11 and the front passage hole 13, as shown in FIGS. 6 and 7.

As shown in FIGS. 2 and 6, each air exhaust hole 15 has an outer end opened on the outer surface of the upper shell body 5A, and the open end is covered with a ventilation gap 17 in the lower shell body. 5B is formed, thereby preventing rain from entering the air exhaust hole 15. The ventilation gap 17 is open at the top and rear, and is closed at the bottom by the stepped portion 18 of the lower shell body 5B. The stepped portion 18 slopes downward at the rear,
This makes it easier to drain rain that has entered the ventilation gap 17.

In FIG. 4, reference numeral 19 denotes a chin belt fixed to the inner surface of the shell upper body 5A with rivets (not shown).

Next, the operation of this embodiment will be described.

If an operator wearing the helmet H of the present invention leaves the sliding cover 12 open while driving a motorcycle, the wind will enter the air intake hole 11 of the helmet body 1 and open the fitting pad 9. Pass through the front passage hole 13,
After passing through the breathable lining 10 while being dispersed, it flows upward along the forehead of the operator, backward along the ventilation groove 14 of the top pad 8, passes through the lining 10 again, and passes through the rear passage hole 16 and The air is discharged to the rear of the cap body 1 through the air discharge hole 15. Note that a part of the running wind that has entered the air intake hole 11 can also flow into the inside of the cap body 1 through the overlapping part between the inner circumferential surface of the buffer liner 6 and the fit pad 9. The wind inside the vehicle is dispersed. As described above, the inside of the cap body 1 is efficiently and evenly ventilated, and the user's head can be cooled.

By the way, the front passage hole 13 is formed as a vertically long elongated hole, and the ventilation groove 14 is provided in the top pad 8 on an extension of the elongated hole, so that air can flow from the front passage hole 13 to the ventilation groove 14. The flow is relatively smooth, promoting ventilation within the cap body 1.

In addition, since only the lower open end of the fit pad 9 is a fixed end, the air intake hole 11 and the through hole 13 may not be vertically aligned due to errors in assembling the fit pad 9 to the buffer liner 6 or misalignment when wearing the helmet. Even if some misalignment occurs in the direction, since the through hole 13 is a long hole vertically longer than the inner diameter of the air intake hole 11, both holes 11 and 13 can always be accurately aligned regardless of the misalignment. The wind guide effect through the above-mentioned through hole 11 can always be effectively exhibited.

In addition, the outer opening of the air exhaust hole 15 has a cap body 1.
Since a negative pressure is generated by the flow of the traveling wind along the outer surface of the vehicle, the exhaust effect from the air outlet holes 15 is well performed, and this also facilitates ventilation.

Further, when the running wind passes through the lining 10 after passing through the through hole 13, the lining 10 acts as a filter and filters the air, so that the forehead of the operator facing the front through hole 13 is protected from dust. prevent it from getting dirty.

Furthermore, the air intake hole 11 and the front passage hole 13,
Since the air exhaust hole 15 and the rear passage hole 16 have different shapes and partially overlap each other, a part of the opening edge of the air intake hole 11 is covered by the highly flexible fit pad 9. , the air intake hole 11 can alleviate the feeling of depression on the operator's forehead, and since the front and rear through holes 13 and 16 are covered with the lining 10, these through holes 13 and 16 can be The lining 10 can prevent the feeling of depression caused by the helmet H, thereby improving the wearing comfort of the helmet H.

Moreover, since the front and rear passage holes 13 and 16 have a cross-sectional area equal to or larger than that of the air intake hole 11 or the air discharge hole 15, the ventilation resistance does not increase.

Figures 8 and 9 show a second embodiment of the present invention, in which a front passage hole 13 and a rear passage hole 16 of the foot pad 9 (only the front passage hole 13 is shown in the figures).
It has the same structure as the previous embodiment except that it is formed into a notch-like long hole with one end open toward the ventilation groove 14 of the top pad 8, and in the figure, corresponding parts to the previous embodiment are shown. The same symbols are attached.

According to this second embodiment, the front passage hole 13 and the rear passage hole 16 are closer to the ventilation groove 14 of the top pad 8, so that the introduction and exhaust of air into the ventilation groove 14 can be facilitated. .

In the present invention, when forming the ventilation grooves 14, the top pad 8 is divided into a plurality of pieces, and these pieces are attached to the buffer liner 6 at intervals so as to define the ventilation grooves 14 between them. It may also be glued.

C. Effects of the invention As described above, according to the invention, the fit pad is superimposed on the inner peripheral surface of the buffer liner so as to allow ventilation between the pad and the inner peripheral surface, and the upper open end of the pad is the free end. The lower opening end of the fit pad is fixed to the cap body, and a through hole passing through the inside and outside of the fit pad is bored corresponding to the air intake hole in the front wall of the cap body, and the through hole is configured to allow the air to pass through the fit pad. The width of the hole is set smaller than the inner diameter of the air intake hole so that the fitpad covers a part of the air intake hole, and the width is set above and below the inner diameter so that the cross-sectional area is equal to or larger than the air intake hole. It is formed into a long hole that extends in the direction,
A ventilation groove is provided on the ceiling surface of the cap body along the extension line of this hole, so that the running wind taken into the air intake hole can pass through the hole and reach the inside of the fit pad without being obstructed by the fit pad. Moreover, the introduced air can be reliably directed to the above-mentioned passage groove along the extension line of the passage hole, and the cooling air can be smoothly circulated within the groove. Combined with the effect that ventilation is also carried out between the overlapping surfaces with the inner circumferential surface of the liner and the cooling air is dispersed within the cap body, the overall ventilation efficiency within the cap body can be greatly increased.
The head of the helmet wearer is accurately cooled.

In addition, since the upper open end of the fit pad is a free end, the air intake hole and the through hole may be slightly misaligned in the vertical direction due to errors in assembling the fit pad to the buffer liner or misalignment when wearing the helmet. Even if this occurs, since the through hole is a long hole that is vertically longer than the inner diameter of the air intake hole, it is possible to always ensure that the through hole and the air intake hole face each other accurately regardless of the positional deviation. Therefore, the air guiding effect can always be effectively exerted through the above-mentioned through holes.

Furthermore, by setting the width of the through hole to be smaller than the inner diameter of the air intake hole so that the footpad covers a portion of the air intake hole, the feeling of depression given to the user of the air intake hole can be reduced. Since the shock can be effectively alleviated by using a fit pad, it is possible to obtain a helmet that is comfortable to wear even though the empty intake hole is specially provided in the buffer liner. Also,
Even though a part of the air intake hole is covered by the fit pad, ventilation is improved by making the hole a long hole and making its cross-sectional area equal to or larger than that of the air intake hole. Since the increase in resistance can be suppressed as much as possible, there is no risk that the air guiding effect of the through hole will be impaired.
