Description

The present invention relates to a water bottle suitable for use in a bicycle competition.

  In sports using bicycles, in particular, in bicycle competitions, it is a general rule to drive a bicycle for several hours to several tens of hours and compete for the required time. In such a competition, since the athlete is forced to exercise with sweating continuously, hydration during the competition is indispensable in consideration of the athlete's health. As a hydration method, usually, hydration by a water bottle (also referred to as a water supply bottle, hereinafter referred to as a bottle) attached to a bicycle body frame is widely performed. In addition, bottles for athletes in current bicycle competitions generally have a true circular cross-sectional shape.

  However, standard bottles with a diameter of about 7.5 cm are used for these general bottles, while the body frame has a diameter of about 2 to 5 cm. In this case, as viewed from the vehicle body traveling direction, it protrudes in the width direction, which increases the front projection area and contributes to an increase in air resistance during traveling.

  The maximum running resistance in cycling is air resistance, and this air resistance increases in proportion to the square of the speed, so how to reduce this greatly improves the competition record. A variety of products that reduce air resistance, such as bicycle racing wheels, uniforms, and helmets, are on the market.

However, with regard to water supply bottles, an attempt has been made to improve this shape in order to reduce air resistance in the long history of bicycling due to the fixed idea that a cylindrical shape with a perfect circular cross section is common. No such product was released.

A bottle with a perfect circular cross-section, which is a conventional bicycle bottle, increases the front projection area when the bicycle is worn, and contributes to an increase in air resistance, which is the maximum running resistance in a bicycle competition.
The present invention has been made to improve the disadvantages of the conventional bottles, and realizes a bottle that can prevent an increase in the front projection area when the bicycle is worn and reduce an increase in air resistance when the bicycle is running. The purpose is to do.

  According to the first aspect of the present invention, a part of a side surface of a cylindrical bottle is formed in a semicircular concave shape so that the cylindrical bottle can be fitted and closely attached to a bicycle body frame.

  In addition, when the bottle is attached to the bicycle by forming the remaining surface other than the concave portion into an oval shape or an oval shape, the bottle is prevented from protruding in the side surface direction and the front projection area is increased. An increase in air resistance can be prevented.

  The second aspect of the present invention is characterized in that, when a bottle is mounted on a bicycle, the bottle upper surface on which the bottle lid is disposed is obliquely formed so as to be horizontal or substantially horizontal. As a result, the front projected area can be further reduced.

A third device is a device for attaching a bottle having the shape of the first and second devices to a bicycle or the like, and a fixing member having a concave surface that is in close contact with the frame of the bicycle, and is fixed to the fixing member. The bottle holding part is characterized in that the bottle holding part is linearly formed of a flexible material.

When a bottle is attached to the body frame of a bicycle, it is possible to prevent an increase in air resistance by using the bottle of the above shape. Therefore, the influence of air resistance during cycling competition, when driving alone or when the headwind is strong, etc. In a situation where it is easy to receive, it is aerodynamically advantageous compared to a bicycle equipped with a conventional bottle, and the running speed can be improved with less muscle strength.

[First Embodiment]
Hereinafter, the bottle of the present invention will be described with reference to embodiments.
FIG. 1 is a perspective view of the bottle of the present embodiment. The bottle 1 includes an upper flat surface portion 3 and a side surface portion 4 on which a lid portion 2 is disposed, and a bottom portion 6 of the bottle, and a concave portion 5 is formed in a part of the side surface portion 4.

FIG. 2 is a schematic view showing a cross section of the bottle 1 attached to the body frame 7 of the bicycle. The concave portion 5 of the bottle 1 is tightly fitted to the curved surface of the body frame 7.
The width of the bottle 1 (the width W of the line AA in FIG. 2) is substantially the same as the diameter of the body frame 7, or if the width of the bottle 1 is larger than the diameter of the body frame 7, It is preferable that the plane cross section constituted by the frame 7 and the side surface of the bottle 1 is a streamline type. Moreover, although the cross-sectional shape of the bottle 1 is an oval in FIG.1 and FIG.2, this may be an ellipse.

As shown in FIG. 2, the concave portion 5 of the bottle 1 is fitted into a body frame 7 of a bicycle and fixed with a fixing tool (not shown). This fixing tool will be described later.
In order to further reduce the air resistance, the lid portion 2 is formed so as to sink from the upper plane portion 3, that is, the upper plane portion 3 and the upper portion of the lid portion 2 are in the same plane. preferable.

  According to this bottle, it is necessary to form a recess that fits into the vehicle body frame, but the inner capacity of the bottle is not sacrificed by increasing the distance to the multi-end of the recessed portion. .

[Second Embodiment]
In this embodiment, the upper plane 3 of the bottle 1 is formed so as to be oblique to the longitudinal axis of the bottle 1.
That is, as shown in FIG. 3 which is a schematic view showing a state in which the bottle 1 is attached to the bicycle, the body frame 7 of the bicycle is normally formed to be inclined rather than in the vertical direction. However, if it is formed perpendicular to the longitudinal direction of the bottle 1, the front projection area is increased by the upper surface of the end portion located opposite to the concave portion 5 of the bottle 1, and is affected by the wind pressure. Therefore, it is preferable that the upper surface 3 of the bottle 1 can be attached so as to be parallel to the horizontal direction (X direction in FIG. 3). Therefore, it is preferable to form the upper plane 3 of the bottle 1 obliquely in the bottle longitudinal direction.

[Third Embodiment]
The third embodiment relates to a fixture (referred to as a bottle cage, bottle holder, etc.) for attaching the bottle 1 to a bicycle body frame 7.

As shown in FIG. 4, the fixture includes a plate-like fixing member 10 formed so as to be in close contact with the curved surface of the vehicle body frame, and two support collars 11 formed so as to protrude from the lower portion thereof. It consists of two press contact parts 12 formed by bending upward from the support collar part 11 and a bottle holding part made up of a support part 13 or the like that connects the press contact parts 12. A fixing screw insertion hole 14 is formed in the fixing member 10, and the fixing tool can be fixed to the bicycle by the screw.
The bottle 1 can be fixed to the bicycle by inserting the bottle 1 into a space formed by the fixing member 10 and the support portion 13 of the bottle holding portion.

In this fixture, the support flange 11 and the pressure contact portion 12 are preferably formed of a metal material that is a flexible member having a spring property. Thereby, the inserted bottle 1 can be stably fixedly supported.
It is preferable that the material of the fixture is as light as possible.

Schematic which shows the state which attached this invention to the bicycle. Schematic which shows an example of the instrument for attaching the bottle of this invention to a bicycle.
