Description

[Detailed explanation of the invention] A. Purpose of the invention (1) Industrial application field The present invention is mainly used for helmets used by occupants of motorcycles, and in particular for helmets that can introduce or block running wind into the cap of the helmet. related to ventilation equipment.

(2) Prior art As a ventilation system for the above-mentioned helmet, for example, an air guide hole is bored in the front wall of the helmet body to communicate the inside and outside of the helmet body and introduce running wind into the inside of the helmet body, and It is conventionally known that a visor is attached that projects forward from the wall surface, and an air guide path is defined within the visor for guiding the traveling wind to the air guide hole (Japanese Patent Laid-Open No. 60-28505 (see publication).

(3) Problems to be solved by the invention In the conventionally known device described above, the air guide path in the visor was always in a conductive state, so the air flow constantly flowed into the air guide hole regardless of the intention of the wearer. There was a problem with the introduction. In addition, in order to solve this problem,
For example, as shown in Japanese Utility Model Application Publication No. 58-45327, if the cap body is provided with a means for opening and closing the air guide hole,
This complicates the structure of the cap body itself, and other problems arise, such as the opening and closing operations of the cap being obstructed by the visor.

In addition, in the above-mentioned conventionally known device, when the shield plate covering the front opening of the cap body is provided close to the front wall of the cap body, it is necessary to avoid interference with the visor that protrudes forward from the front wall of the cap body. The shield plate had to be removable rather than vertically swinging,
This has the disadvantage that the range of application is greatly limited.On the other hand, if the shield plate is made to swing up and down and is extended forward until its upper edge overlaps the front end of the visor, the shield In the closed position, the plate blocks the front end opening of the air guide path in the visor, making it difficult to introduce the running air into the air guide hole.

The present invention has been proposed in view of the above, and aims to provide a ventilation system for a helmet that can solve all of the problems and inconveniences of the conventional ones.

B. Structure of the device (1) Means for solving the problem In order to achieve the above object, according to the present invention, the front wall of the cap body communicates with the inside and outside of the cap body to introduce running wind into the inside of the cap body. In the helmet, the visor is provided with an air guide hole and a visor, and the visor is formed so as to be inclined forwardly and downwardly along a substantially tangential direction of the surface of the cap body. The cap body has a window that faces the opening of the hole and has a wider opening area than the opening, and the cap body has a closed position that covers the front opening of the cap body below the window, and a window that opens the front opening. A shield plate that can swing open and close between an open position and a shield plate is attached, and the visor is further provided with an opening/closing lid that can open and close the window.

(2) Function By opening and closing the opening/closing lid of the visor, it is possible to arbitrarily switch between introducing the traveling air into the cap body through the window and the air guide hole and blocking it. Therefore, there is no risk that the opening/closing operation will be obstructed by the visor.

In addition, even though the shield plate is vertically swingable, there is no risk of blocking the visor window in the closed position, so when the window is opened by the opening/closing lid, the effect of introducing the running wind into the cap body is reduced. You can definitely get it.

In this case, since the opening/closing lid 25 and the visor 13 are flush with each other, there is no gap between the periphery of the window 20 and the outer periphery of the lid 25, and it is possible to reliably prevent wind from entering the cap body 2. can.

C. Effect of the invention As described above, according to the invention, an air guide hole is formed in the front wall of the cap body to communicate with the inside and outside of the cap body to introduce running wind into the inside of the cap body, and the visor In the helmet, the visor is formed to be inclined forward and downward along a substantially tangential direction of the surface of the cap body, and the opening of the air guide hole faces the opening. The cap body has a wide window, and the cap body includes a shield that can be opened and closed between a closed position that covers the front opening of the cap body below the window and an open position that opens the front opening. A plate is attached to the visor, and the visor is further provided with an opening/closing lid that can open and close the window, so that by opening/closing the opening/closing lid of the visor, traveling wind is introduced into the cap body through the window and the air guide hole. It is convenient to be able to switch between shutting off and shutting off at will, and since the opening/closing lid is installed on the visor, there is no need to specially modify the cap body itself to install the opening/closing lid, and the opening/closing operation is controlled by the visor. There is no risk of being disturbed. In addition, even though the shield plate is vertically swingable, there is no risk of blocking the visor window in the closed position, so when the window is opened by the opening/closing lid, the effect of introducing the traveling wind into the cap body is reduced. This can definitely be achieved.
