JP2019044303A - Sunshade board for motorcycle helmet - Google Patents

Abstract

To prevent a situation that a temperature in a helmet is high when driving a motorcycle in the summer sun.SOLUTION: A sunshade board is attached to shield a helmet from direct sunlight, because a temperature inside a highly airtight helmet becomes high when driving a motorcycle under the summer sun. It is possible to prevent direct sunlight from hitting the helmet by attaching a shield integrated type sunshade board or a sunshade board with a collar using a shield attachment mechanism or snap button originally attached to the helmet, and heat of the sunshade board is not transmitted directly to the helmet because an air space is provided between the sunshade board and the helmet, and inside of the helmet is not filled with the heat because the air in the air layer flows by wind when traveling, and it is possible to prevent the temperature in the helmet from rising because a place under the shade board can be shaded in the helmet.SELECTED DRAWING: Figure 1

Description

The present invention relates to a sunshade that aims to suppress an increase in temperature in a helmet when the helmet is worn in summer.

As measures against heat of a motorcycle helmet in summer, a vent is provided at the forehead of the helmet, and a method of coloring a shield black or brown like sunglasses to prevent sunlight is known.
In addition, following patent document 1 can be mentioned as a well-known technique relevant to this invention.

Japanese Patent Application Publication No. 2007-51397

However, the method described above is not sufficient, and when driving a motorcycle in the summertime in summer, there is no air conditioning like a passenger car, wears a helmet and both hands are closed to hold the steering wheel, so they can wear a parasol or a hat. I can not suffer. In particular, the inside of the helmet is highly airtight, so the temperature tends to rise, and there is a risk of heatstroke.

The present invention mounts a shading plate on the top of the helmet for the purpose of suppressing the temperature rise in the helmet.

Awnings prevent direct sunlight from reaching the top of the helmet and create a shade under the sunkling. Furthermore, since the air layer is provided between the sun protection plate and the helmet, the heat of the sun protection plate is not directly transmitted to the helmet, and the air of the air layer is also flowed by the wind during traveling, so the heat effect is not absorbed and the cooling effect can be enhanced. .

FIG. 1 is a schematic perspective view of a full-face-type helmet according to the present invention in which a shield integrated sunshade plate is attached. It is sectional drawing which showed the positional relationship of the sunshade board which concerns on this invention, a helmet, and an air layer. It is a schematic perspective view of a state where a shield integrated sunshade plate was attached to an open face helmet according to the present invention. It is the schematic perspective view which looked at only the shield integrated sunshade board attached with the snap button which concerns on this invention from diagonally downward. It is a schematic perspective view of the state which attached the shading board with a collar to the helmet of the open face type | mold which concerns on this invention.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.
In FIG. 1, the shading plates 1 and 2 are integrally molded using the material of a shield. Since the shield plate is attached by using the shield attachment mechanism 3 originally attached to the helmet, it is safe without the fear of coming off during traveling. The shield part 1 of the sunshade plate is generally called a mirror shield, and the outside is mirror-finished silver. The inside is a transparent color with a black or brown color like sunglasses, and you can ensure visibility even if you lower the shield. The rear part 2 of the shade plate is coated with a silver or white paint on the outside and is in a state capable of completely blocking or reflecting sunlight.
In summer, as shown in FIG. 1, the sunshades 1 and 2 are placed in such a position as to wrap the top of the helmet to prevent the helmet from being heated by direct sunlight.

In FIG. 2, since there is an air layer 7 between the cross-sectional view 5 of the shading plate and the cross-sectional view 6 of the helmet, even if the shading plate is heated by direct sunlight, the heat is not transmitted directly to the helmet.

In FIG. 3, in the case of the type having a snap button on the forehead of the helmet, this is used to attach the sunshade plate. The sun shields 8 and 9 are integrally molded in the same manner as the sun shields 1 and 2. The shield 8 is a mirror shield, and the outside of the rear portion 9 is coated with a silver or white paint.

In FIG. 4, the snap button 10 has a slit in the shading plate and can slide to the left and right. This makes it possible to attach helmets having different pitches between snap buttons. The urethane resin 11 is bonded to the inside rear of the shading plate. As a result, an air layer can be secured between the shading plate and the helmet, and the shading plate can be prevented from fluttering while traveling. The same urethane resin is attached also to the sunshade board of FIG. 1 and FIG.

In FIG. 5, it is the sunshade 12 with a collar which diverted and attached the snap button originally attached to the helmet like FIG. The material may be inexpensive plastic since there is no shield. A silver or white paint is applied to the outer side of the entire shade plate and the upper surface of the collar.
