Abstract

(57) [Summary] [Structure] The helmet visor 1 that is mounted by protruding from the upper portion 2a of the helmet 2 to the front portion of the helmet 2.
In addition, while having a circulation gap 6 between the outer peripheral surface of the helmet 2 and a plurality of wind vents 7 along the front portion 2c of the helmet 2, the visor front portion 1c projecting to the front portion of the helmet 2 is provided. An air vent hole 9 is provided between the visor central portion 1d and the rear portion 1e located on the upper portion 2a of the helmet 2 in a downstream region of the exhaust hole 8 which is provided in communication with the inside of the helmet 2. I am trying. [Effect] Since the running wind taken into the visor is allowed to escape and the air accumulated in the helmet 2 can be extracted to the outside of the helmet 2, it has both a wind pressure reducing mechanism and a ventilation mechanism, which is practical. It was excellent.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a helmet visor having both a wind pressure reduction mechanism and a ventilation mechanism.

[0002]

[Prior art]

 Conventionally, a helmet visor equipped with a wind pressure reduction mechanism and a helmet visor equipped with a ventilation mechanism exist independently. A helmet visor equipped with a wind pressure reduction mechanism is mounted, for example, so that a ventilation gap is provided between the helmet visor and the outer peripheral surface of the front portion of the helmet and the front portion of the helmet is projected by a hook or the like. The running wind taken into the visor is allowed to escape from the ventilation gap.

A helmet visor provided with a ventilation mechanism, for example, closes the ventilation gap and provides a suction hole at the front of the helmet. Then, the running wind is taken into the helmet through the intake hole, and the taken running wind is taken out of the helmet through the exhaust hole provided at the rear part of the helmet.

[0004]

[Problems to be solved by the device]

 Therefore, a helmet visor with a wind pressure reduction mechanism has the function of letting the running wind escape from the visor, and a helmet visor with a ventilation mechanism has the function of taking the running wind into the visor. is doing. Therefore, in the past, it was not possible to provide a helmet visor having both a wind pressure reduction mechanism and a ventilation mechanism.

Therefore, the present invention has been made for the purpose of providing a helmet visor having both a wind pressure reduction mechanism and a ventilation mechanism, which cannot be provided by the conventional helmet visor described above.

[0006]

[Means for Solving the Problems]

 Therefore, the helmet visor of the present invention is assumed to be mounted so as to project from the upper portion 2a of the helmet 2 to the front portion of the helmet 2, and has a circulation gap 6 between the outer peripheral surface of the helmet 2 and the front portion of the helmet 2. A plurality of wind vents 7 are provided in the front part 1c of the visor protruding along the front part 2c of the helmet 2, and between the central part 1d of the visor located at the upper part 2a of the helmet 2 and the rear part 1e, there is a hem. The air vent hole 9 is provided in the downstream region of the exhaust hole 8 which is provided in communication with the inside of the hood 2.

[0007]

[Action]

 Since the helmet visor of the present invention has the above-described configuration, the traveling wind taken into the visor can be released through the circulation gap 6 and the air vents 7 and 9. Further, the air retained in the helmet 2 can be extracted from the exhaust hole 8 to the outside of the helmet 2 by the pulling force of the traveling wind that is made to escape through the circulation gap 6 and the air vent hole 9.

[0008]

【Example】

 Hereinafter, the construction of the helmet visor of the present invention will be described in detail with reference to the drawings shown as examples. FIG. 1 shows a state in which the helmet visor of the present invention is mounted on a helmet, and the helmet visor 1 is mounted by protruding from the upper portion 2a of the helmet 2 to the front portion of the helmet 2. In this embodiment, screws 5 are inserted into the screw holes 3 provided on both sides 2b of the helmet 2 through the mounting holes 4 provided on the both-side extending portions 1a of the helmet visor 1, and the screws are fixed on both sides of the helmet visor 1. Although the portion 1b is fixed to the upper portion 2a of the helmet 2 with an adhesive tape (not shown), the helmet visor 1 can be attached to the helmet 2 by other appropriate means.

The helmet visor 1 has a flow gap 6 at an interval of 3 to 5 mm between the helmet 2 and the outer peripheral surface of the helmet 2, and the helmet visor 1 has a front portion 1 c protruding from the front portion of the helmet 2. A plurality of air vent holes 7 are provided along the front portion 2c of the. In this embodiment, the wind vent hole 7 is an elliptical hole 7a or a triangular hole 7b along the front portion 2c of the helmet 2, but it is not limited to these shapes and can be appropriately shaped.

Further, the helmet visor 1 is located in the downstream region of the exhaust hole 8 provided in communication with the inside of the helmet 2 between the visor central portion 1d located on the upper portion 2a of the helmet 2 and the rear portion 1e. Then, the wind vent hole 9 is provided. In this embodiment, the exhaust holes 8 are plural and the air vent holes 9 are single. However, conversely, the exhaust holes 8 may be single and the air vent holes 9 may be plural, or both of them may be plural. In the embodiment, the wind vent hole 9 is an elliptical hole extending along the upper portion 2a of the helmet 2, but the shape is not limited to this and can be implemented as appropriate.

When the Helmet equipped with the helmet visor of the present invention configured as described above is worn, traveling wind taken into the visor during driving of a motorcycle or the like is distributed to the circulation gap 6, the wind vent hole 7, The air pressure applied to the visor is reduced because it can be released through 9. Further, the air retained in the helmet 2 is extracted from the exhaust hole 8 to the outside of the helmet 2 by the pulling force of the running wind that is made to escape through the circulation gap 6 and the air vent hole 9, and the inside of the helmet 2 is ventilated. can do .

[0012]

[Effect of device]

 The helmet visor of the present invention is configured as described above, and allows the running wind taken into the visor to escape and at the same time, the air retained in the helmet 2 can be extracted to the outside of the helmet 2. As a result, it has both a wind pressure reduction mechanism and a ventilation mechanism, making it highly practical.
