Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a resistance reducing device for a rider, which is mainly worn by a rider in a motorcycle race.

(Prior Art) It is no exaggeration to say that the key to winning a motorcycle race is how to reduce wind resistance during high-speed running.

For this reason, ingenuity has been put into the overall shape and structure of the motorcycle, the shape of the fairing, and the material and shape of the rider's suit, as well as the rider's riding posture to reduce wind pressure resistance when riding at high speeds. It is planned.

(Problem that the invention aims to solve) However, if you only wear a conventional rider suit, the wind that hits the entire surface of the rider during high-speed riding will not flow smoothly backwards, and vortices will easily occur on the back of the rider. There was a limit to how much wind resistance could be reduced.

In view of the above, an object of the present invention is to provide a resistance reducing device for a rider that can reduce wind pressure resistance.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a chest plate part that is applied to the rider's chest, a backpack part that is applied to the upper back of the rider, and a chest plate part and a backpack part. and a shoulder rest part that connects and contacts the upper surface of both shoulders of the rider, the chest part projects forward in a substantially conical shape, the backpack part projects rearward in a substantially triangular prism shape, and the twill line part thereof extends upward. The present invention provides a drag reduction device for a rider who is jumping.

(Function) According to the present invention, the wind that hits the entire surface of the rider when the motorcycle is running at high speed can be smoothly guided to the rear by the chest plate that protrudes forward in a substantially conical shape. To reduce the wind pressure resistance to motorcycle running by suppressing the air spoiler action of a backpack part in which the wind protrudes rearward in a substantially triangular prism shape and its twill part jumps upward, thereby reducing wind pressure resistance. I can do it. The backpack portion also has the effect of holding the rider, and by extension the motorcycle, against the road surface, contributing to running stability.

Further, according to the present invention, the chest plate and the backpack are connected by the shoulder rest and are worn as one body by the rider, so that the wind pressure applied to the chest plate and the backpack is transferred to the shoulder rest. It also has the effect of being able to be supported by the rider's shoulders.

(Embodiment) The embodiment of the present invention shown in the drawings relates to a resistance reducing device for riders mainly composed of foamed synthetic resin.

This resistance reducing device for riders consists of a chest part 1, a shoulder rest 2, and a backpack part 3, which are integrally molded from a foamed synthetic resin such as foamed polystyrene or foamed urethane.

The surface of the main body 4, which has a sponge-like interior and a relatively hard outer layer, has a first layer.
As shown in the figure, an undercoating film 5 colored in a predetermined color and a smooth coating film 6 having a transparent and smooth surface.
is coated. Furthermore, a base cloth 7 made of nylon cloth, cotton cloth, etc. is adhered to the inner surface of the resistance reducing device for the rider, and the portions of this base cloth 7 located on the back surface of the breastplate portion 1 and the back surface of the backpack portion 3 are attached with one-touch type adhesives. A detachable fastener 8 is provided.

The breastplate portion 1 is placed on the rider's chest and is formed into a substantially conical shape so as to protrude forward. The apex 9 of this conical portion is preferably formed so as to be located in front of the rider's solar plexus, as shown in FIG. The chest plate 1 is also provided with a plurality of ventilation holes 10 passing through in the lateral direction so that cross winds during riding can pass therethrough, thereby reducing the wind pressure exerted on the rider by the cross winds.

The backpack portion 3 is placed on the upper back of the rider, and is formed so as to protrude rearward in a substantially triangular prism shape and to have its twill portion 11 spring upward. As shown in FIG. 3, this twill line portion 11 is preferably formed so as to be located behind both shoulder blades of the rider.

The shoulder rest part 2 is composed of a pair of band-shaped curved parts 2a, connects the chest part 1 and the backpack part 3, and comes into contact with the upper surfaces of both shoulders of the rider.

The breastplate part 1 and the backpack part 3 are connected by a wear strap 12 that removably connects the lower portions of both sides of each. As shown in FIGS. 2 to 4, the rider's resistance reducing device is constructed by utilizing the wearing string 12 and crimping the fastener 8 to a corresponding fastener (not shown) of the rider suit 13. , worn.

Thus, when riding a motorcycle, the rider resistance reducing device of the present invention operates as explained in the (Function) section, and can reduce wind pressure resistance. As shown in FIG. 4, when the chest plate 1 is applied to the fuel tank 14 of the motorcycle, there is an advantage that the motorcycle can bear the weight of the upper body in the forward leaning position.

The present invention can be configured in various ways other than those shown in the above-mentioned embodiments. For example, it is also possible to form the rider's resistance reducing device integrally with the rider's suit.

(Effects of the invention) Since the present invention has the above structure and function, it is possible to reduce wind pressure resistance when riding a motorcycle, and to provide a rider resistance reducing device that can be worn by a rider in a stable state. .
