Description

[Detailed description of the invention] (Technical field to which the invention pertains) This invention relates to a helmet, and more specifically to a helmet equipped with a ventilation device that is worn when riding a motorcycle or a car.

(Prior art) There are two types of helmets that are generally worn when driving a motorcycle or car: full-face type, jet type, etc. When wearing these helmets, a shield is attached to the front opening to prevent the wind from directly blowing into the helmet. In many cases, they try to avoid hitting the eyes.

As a result, sufficient wind does not enter the inside of the helmet, and the head on which the helmet is worn becomes stuffy and sweaty on the forehead, making it extremely uncomfortable.

Therefore, as a means to solve the above-mentioned problems, it may be possible to open an air intake hole or the like that communicates with the inside of the helmet body in a place near the edge of the front part of the helmet body where the wind hits from the front. Drilling holes in such locations reduces the strength of the helmet itself, potentially affecting safety. In addition, in consideration of strength in the full-face type helmet, an intake structure is provided in the chin guard part below the window hole in the front, and the air taken in is guided to the upper part of the helmet and blown out. There is something. However, with any of the above-mentioned intake structures, when air is blown out through the cushion material inside the helmet, the flow of air is obstructed by the cushion material, and sufficient ventilation cannot be expected.

(Purpose of the invention) The purpose was to create a simple design without affecting the strength of the front part of the helmet, which is the most suitable part for taking in air and also the most important part for absorbing shock. An object of the present invention is to provide a helmet having a structure with a ventilation device capable of introducing air into the helmet.

A further object of this invention is to provide a helmet in which the air introduced into the helmet is ventilated while directly hitting the head body without being obstructed by the cushioning material.

(Summary of the invention) In this invention, a duct defining an air intake is attached to the window edge of the forehead of the helmet body, and a guide groove communicating with the air outlet of the duct is installed inside the helmet body, and a shock absorbing liner is connected to the guide groove. This helmet is provided with a ventilation device that is formed by cutting out a side cushion that is worn on the inside, and in which an air outflow groove is defined by cutting out a part of the side cushion located on the back of the head.

Further, the helmet body provided with the ventilation device may be either a full-face type or a jet type.

(Example) Hereinafter, an example of the present invention will be explained with reference to the drawings for a full-face type helmet. A is a helmet body, and B is a duct.

The helmet body A includes a cap body 1 molded from a material such as FRP, and a shock absorbing liner 2 formed from polystyrene foam or a material with shock absorption performance equal to or higher than the polystyrene foam fitted to the inside of the cap body 1. , a chin guard 3 made of polystyrene foam extending from the chin to the left and right temples in the cap body 1, and attached bodies such as a side cushion 4 and a head cushion 5 attached to the inner surface of the shock absorbing liner 2, not shown. It consists of a chin strap.

The cap body 1 of the helmet main body A has a generally rectangular window hole 6 in the front surface so that the eyes are exposed. It is opened and closed by a shield 7.

The side cushion 4 attached to the inside of the shock absorbing liner 2 is made of a cushion material 4 with good breathability.
a. For example, a coarse mesh polyurethane foam is covered with a lining fabric 4b that is comfortable to the touch and has good breathability. Flat ducts B are formed on both left and right sides of the upper hole edge of the window hole 6 in the helmet body A. is fixed and held by an adhesive and pressing band 14. The lining cloth 4b, which comes into direct contact with the head, is made of a special water-absorbent cloth that carries all the sweat to the back side of the cloth, so that it always maintains a dry feel.

The duct B is made of soft synthetic resin or rubber material, so that in the unlikely event that a shock is applied to the helmet, the duct B will deform and damage the head. I have made sure that there is no such thing. The duct B is made of the above-mentioned material and is formed into a flat rectangular shape with an open front and upper surface, and its depth is set to reach the side cushion 4 from the front edge of the window hole 6. Two flat plate-like partitions/ribs 8a are arranged vertically in parallel toward the rear end, and an air intake inlet 9 is defined at the front end by a horizontal band 8b connecting the partitions/ribs 8a. In addition, the rear portion of the lower surface is curved in an arcuate shape toward the upper end surface so that the incoming air flows toward the upper surface of the rear portion, that is, toward the inner surface of the shock absorbing liner 2.

To install the duct B, insert the duct B between the holding band 14 fixed to the lower surface of the upper edge of the window hole 6 so that its upper opening joins with the lower surface of the front end of the shock absorbing liner 2. The horizontal band 8b on the front side of the upper surface is fixed and held by adhering to a rubber edging 15 fixed to the edge of the window hole of the cap body 1 via an adhesive. Accordingly, duct B
The upper surface from the front to the rear is the shock absorbing liner 2.
, and only the rear upper surface is covered with shock absorbing liner 2.
The guide groove 16 protrudes inward from the side cushion 4 and is inserted into the guide groove 16 formed by cutting out the side cushion 4.

Therefore, the air entering from the air intake port 9 of the duct B flows into the side cushion 4 through the opening on the rear upper surface.
The air flows out into the guide groove 16 formed by notching the helmet body A, and is blown out to the inner top of the helmet body A.
The head and body are cooled.

In addition, the air blown into the inside of the helmet is passed through an air outflow groove 1 formed by vertically cutting out the rear part of the side cushion installed in the helmet body A.
7 to the outside from the rear lower side of the helmet. This is because the rear side of the neck, which protrudes downward from the helmet body A, becomes a negative pressure, and the air inside the helmet is drawn out by the flow of air within the helmet body A.

A hole 11 communicating with the air intake port 9 of the duct B is provided in the shield 7 for opening and closing the window hole 6 of the helmet body A.

Also, the hole 11 of the shield 7 may be left open in the same shape as the air intake port 9, but the hole 11 of the shield 7 may be opened in the same shape as the air intake port 9.
Of course, it is also possible to provide one opening/closing means to freely adjust the flow rate. As a means for opening and closing the hole 11, a synthetic resin mounting frame 12 and a slide plate 13 are attached to the shield 7 side, and by moving the slide plate 13 up and down, the opening amount of the hole 11 is adjusted, and the flow flows into the duct B. Adjust the amount of air.

In addition, in winter when ventilation is not necessary, the hole 11 is closed by operating the slide 13, and the guide groove 16 inside the helmet body A is replaced with an auxiliary side shoe formed in the same shape as the guide groove. Shion 1
8 and fix it to fill the groove.

The above-mentioned duct B may be attached not only to the left and right sides of the aperture edge of the forehead, but also to the middle, or any location selected from these locations.

The above description has been made for a full-face type helmet, but in the case of a jet type helmet, a duct is attached to the lower edge of the forehead as shown in Fig. 6 so as not to obstruct the visibility necessary for running.
Incidentally, the installation of the duct B and the formation of the guide groove and air outflow groove inside the helmet are the same as in the case of the full-face type.

(Effects of the invention) As detailed above, the helmet of the present invention has an air intake defined at the edge of the opening in the forehead of the helmet body, and a long length that reaches inside the shock absorbing liner. A guide groove communicating with the air outlet of the duct is formed inside the helmet body by cutting out the side cushion installed inside the shock absorbing liner. Since the air outflow groove is formed by cutting out a part of the cushion, the air flowing out from the air intake port of the duct flows through the guide groove toward the top of the head, and is blown out inside the helmet, causing the air to flow into the head. is effectively cooled.

Moreover, since the duct is attached without making any holes in the helmet itself, there is no need to reduce the strength of the helmet. Further, since the duct is made of a flexible material, there is no danger from this, and since the duct is installed at the edge of the opening in the forehead, there is no risk of obstructing the visibility necessary for driving. Furthermore, the guide groove that communicates with the air outlet of the duct attached to the window edge and the air outlet groove that exits from the top of the inside of the helmet to the lower rear of the helmet are each formed by cutting out the side cushion that is attached to the inside of the shock absorbing liner. Therefore, there is no problem such as deterioration of the performance of the shock absorbing liner, which functions as head protection required for a helmet. Air not only flows, but also flows in all directions through the interior of the side cushion, providing comfortable ventilation.

In addition, if the hole communicating with the duct opened in the shield can be adjusted to open or close using an opening adjustment means, the shield can block the wind from hitting the face while adjusting the amount of air needed to cool the head. can do.
