Description

[Detailed Description of the Invention] This invention relates to an improvement of the front cowling of a motorcycle that runs at high speeds such as in road races.

Motorcycles that run at high speeds, such as those used in road races, cover the front of the motorcycle with a cowling to reduce air resistance.

A cowling window is connected to the top of the cowling, and the rider looks forward through the cowling window.

If the cowling wind is made smaller, the front projected area will be smaller and air resistance will be reduced, but the rider's helmet will protrude upwards and the rider will be directly exposed to wind pressure, causing fatigue.

Also, turbulence occurs between the cowling wind and the helmet, blowing the wind into the rider's face.

Increasing the cowling window reduces rider fatigue, but increases the projected area and increases air resistance.

This invention has been improved in view of these points, and embodiments of the invention will be described below with reference to the drawings.

The front part of the motorcycle 1 is covered with a front cowling 2, and a cowling window 3 made of a transparent synthetic resin plate or the like is connected to the upper part of the front cowling 2.

Accordingly, in the present invention, an elastic strip 4 is provided which has a cross-section shaped like a square, tapered at the tip, and curved, and is attached along the rear edge of the cowling window 3.

In the figure, a groove 5 is provided at the base end of the elastic strip 4, and the groove 5 is fitted into the rear edge of the cowling window 3 and fixed with adhesive or the like.

When attaching the elastic strip 4 to the rear end edge of the cowling window 3, the elastic strip 4 is attached so that the warp of the elastic strip 4 is opposite to the curved surface of the cowling window 3.

6 indicates a rider, and 7 indicates a helmet.

The effect will be explained.

The air that hits the cowling window 3 while running flows backward along the curved surface of the cowling window 3, and the elastic strip 4
It is then turned upward and flows diagonally backward and upward.

Therefore, the amount of wind hitting the helmet 7 of the rider 6 can be reduced, and the fatigue of the rider 6 can be reduced.

Furthermore, since the elastic strips 4 change the wind flowing upward, less air gets caught in the facial bones of the rider 6.

And Cowling Wind 3 is Rider 6's Helmet 7
Moreover, there is no need to make it so large that it covers it, and it can be made small, with a small frontal projected area and low air resistance.

Moreover, it is sufficient to prepare several types of elastic strips 4 with different lengths and degrees of warpage, and to attach them according to the physique of the rider 6.
Since only one type of cowling wind 3 is required, the cost can be reduced.

As explained above, in this invention, an elastic strip with a cross-section shaped like a square is attached along the rear edge of the cowling window, which is connected to the upper part of the front cowling that covers the front part of the motorcycle. Since the air flowing along the window can be deflected upward by the elastic strips, the amount of wind hitting the rider's helmet can be reduced, and the amount of wind caught in the rider's face can also be reduced, reducing rider fatigue.

A cowling window that is small and has low air resistance is sufficient, and several types of elastic strips can be prepared and used according to the rider, and the cowling window can be made into one type at a low cost.

Furthermore, even if the helmet comes into contact with the elastic strips, vibrations from the engine are absorbed by the elastic strips, and the rider does not feel uncomfortable.
