Description

[Detailed Description of Device] 1). Purpose of the invention [Industrial application] The present invention relates to a bicycle handle. For more details,
The present invention relates to a bicycle handlebar that is improved from a conventional drop handlebar and has a fourth position (grip), which is suitable for cycling cars and racing bicycles.

[Conventional technology]

Conventionally, a drop handle has been used as a handle of a sports bicycle. Generally, the drop type handle has three grips. That is, the first grip portion is between the central portion of the first straight pipe portion extending horizontally from the stem and the first curved pipe portion, and the second grip portion is near the brake fixing member of the second curved pipe portion. The third grip portion is provided between the lower end of the second curved pipe portion and the second straight pipe portion. However, the conventional drop handle leaves various problems for long distance touring and triathlon competition. That is,
It has large air resistance and it is difficult to speed up, and it is hard to withstand long running due to severe fatigue. Therefore, various proposals have been made to solve these drawbacks. For example, actual development 56-76587, actual development 57-29496, actual development 61
-113190, Shoko 60-3029, Shoko 60-10237, Shoko 62-29351, Kaikai Sho 62-214079, JP 63-212189,
There is JP-A-1-132488 and the like. 56-76587 is actually
The center part is squeezed in the radial direction to make it oval, and the air resistance is reduced. In actual opening Sho 57-29496, the shape of the third gripping part in the second straight pipe part is elliptical, and its major axis is 1
Directed inward and outward of the straight pipe part, the inside of which is tilted upward with respect to the outside to facilitate fitting to the hand,
Actual Kaihei 1-113190 has several grips at the front and rear of the handlebar, which have vertical or front-back differences so that the handlebar width can be adjusted to suit the physique of the upper body so that the riding posture can be obtained according to the road conditions. With improved safety and reduced fatigue, Jikken Sho 30-3029, Jikon 60-10237,
JP-A-62-29351 has three grips which are shaped so as to hit almost the front of the palm to reduce fatigue during riding.
62-214079 eliminates the drawbacks of the drop handle,
There is a drop type and an upturn type. However, even in these cases, the tiredness of the arm is severe during long-distance running, and when the pedal is depressed, the power of the hand is lost at these grips, and the force of kicking the pedal is reduced accordingly. There was a flaw. This is because the grip part during high speed running is
This is probably because it is parallel to the running direction. Also, in recent years, triathlon competitions have emerged, and are popular among young people. In triathlons, bicycle races continue after swimming, so with conventional drop handles the arm gets very tired, so to remedy these shortcomings,
A blue horn handle was used, followed by a Scott handle. However, it has been found that these also have safety drawbacks and the like.
63-212189 and JP-A-1-132488 are proposed. However, as a result of earnestly examining these handles, the fatigue surface of these handles is reduced by putting the arm on the first grip portion, and as a result, the center of gravity is located in front of the center point of the body. When moving to the brakes and operating the brakes, there is a danger of becoming leaned forward and plunging into the obstacle from the head,
Further, it has been found that since the grip portions projecting forward of the handle are provided close to each other, a steep handle operation cannot be performed, which is extremely problematic for safety.

[Problems to be solved by the device]

The present invention has been made from the above point of view, and its purpose is to provide a handle for a sports bicycle,
By improving the so-called conventional drop handle and providing it with a new fourth position (grip) that has an angle of 90 ° to 135 ° with the running direction when traveling at high speed,
In particular, it reduces arm fatigue during long-distance travel, and when kicking the pedal during high-speed travel, all the force that was released to the arm is used to kick power to improve running speed and handle operation. It is also to provide a bicycle handlebar that is easy, safe and ergonomically superior.

2). Configuration of the Invention [Means for Solving the Problems] In order to achieve the above-mentioned object, a bicycle handle of the present invention has a center portion supported by a stem and a horizontal symmetrically centered on the center portion. Straight pipe portion extending in the forward or substantially forward direction, a first curved pipe portion that curves forward from the longitudinal end of the first straight pipe portion, and an extension line from the end of the first curved pipe portion. A second straight pipe portion that extends, a second curved pipe portion that curves downward from an end portion of the second straight pipe portion, and a third straight pipe portion that extends on an extension line from the end portion of the second curved pipe portion, It is composed of a third curved pipe portion that curves outward or obliquely downward from the end portion of the third straight pipe portion, and a fourth straight pipe portion that extends on the extension line from the end portion of the third curved pipe portion.

[Action]

When used for sports or as a racing bicycle, by having a fourth position consisting of a third curved pipe section or a fourth straight pipe section, especially when traveling at high speeds, the fourth position becomes the traveling direction. Since it is opened at an angle of approximately 90 ° to approximately 135 ° and has a width that is approximately the same as or slightly wider than the shoulder width, a sudden handle operation can be performed extremely easily. Also, when traveling long distances,
You can increase your endurance with less fatigue because you just put your hand lightly in position. Furthermore, the fourth position is
Since it is close to the brake, it is easy to operate the brake and the safety can be significantly improved. In addition, when traveling in urban areas, it is possible to secure a wide field of view and operability while operating with a natural figure.

〔Example〕

An example of an embodiment of the present invention will be described below with reference to the drawings.
The bicycle handle of the present invention, as shown in FIGS. 1 to 4, has a central portion (1) supported by a stem (20).
And a first straight pipe portion (2) extending horizontally or substantially in the front-rear direction symmetrically with respect to the central portion (1), and curved forward from the longitudinal end of the first straight pipe portion (2). From a first curved pipe section (3), a second straight pipe section (4) extending from the end of the first curved pipe section (3) on the extension line, and an end of the second straight pipe section (4) A second curved pipe portion (5) that curves downward, a third straight pipe portion (6) extending from an end of the second curved pipe portion (5) on an extension line thereof, and a third straight pipe portion (6) A third curved pipe portion (7) curved outwardly or obliquely downward or obliquely backward from the end of the
It is roughly composed of a fourth straight pipe portion (8) extending from the end portion of the curved pipe portion (7) on the extension line thereof.

The first straight pipe portion (2) has a central portion (1) as shown in FIG.
Is symmetrically horizontal with respect to, and forms a first grip portion. In addition, when using for high speed, as shown in FIG. 5, the first straight pipe part (2) is 5 at the boundary with the central part.
It is recommended to incline forward by ~ 30 °. By inclining, the width of the arm is narrowed during traveling, and the posture of forward bending is taken accordingly, so that the air resistance can be reduced. If the angle exceeds 30 °, the sides will open when the first grip portion is gripped during traveling, which makes it difficult to operate the steering wheel, which is not preferable. The cross-sectional shape of the first straight pipe part (2) may be round, but in order to reduce air resistance and make it easier to grip, an air-foil shape with a slightly crushed rear part is preferable because it fits easily on the palm. is there. The brake fixing member (30) is tightly attached to an appropriate position of the second curved pipe portion (5) to form a second grip portion, and the brake lever (31) makes the brake operation easier than the third grip portion. It is easy to do. The angle between the first curved pipe portion (3) and the first straight pipe portion (2) may be approximately 90 ° to 65 °. The smaller the angle, the tighter the side when gripping the second grip,
This is because the air resistance can be reduced. However, 60
If it is less than °, it is difficult to operate the handle, which is not preferable. The cross-sectional shape of the third grip portion may be round, but it is preferable that it is elliptical so that it can fit the palm easily. The third curved pipe section (7) is at a right angle to the traveling direction or a slanting direction or a slanting backward direction from the end of the third straight pipe section (6), that is, an angle of 90 ° to 135 °, and 0 ° to 45 in the direction perpendicular to the running direction
It is provided with an angle of °. Fourth straight pipe section (8)
Is approximately the same as or half the width of an adult's palm.

The cross-sectional shape of the fourth straight pipe section (8) is preferably substantially the same as the shape of the first straight pipe section. Third curved pipe section (7) to fourth
By providing the straight pipe part (8), when dashing at high speed, the fourth gripping part is different from the conventional drop type,
Since it is almost horizontal to the running direction, the force to pull the handle increases,
Therefore, the force to kick the pedal can be increased, and the speed can be increased. Also, the posture of the conventional drop part is maintained even during normal high-speed running, and the arm is stretched appropriately, so that the endurance is increased and the arm width holds the grip part naturally. Since the brake lever (11) is in the immediate vicinity, it is easy to operate the brake for collision. The fourth straight pipe section (8) is
The second curved pipe part (5) may be appropriately inclined from the inner side to the outer side within a range in which the adult's fist is inside the shoulder width and the fist is outside the shoulder width. When the second curved pipe section (5) is inclined inward, the second curved pipe section (5) can protect the hands and is safe even if the bicycle falls, which is suitable for sports. Further, when the second curved pipe portion (5) is inclined to the outside, the arm is stretched forward in a natural state and fatigue is reduced even during long-distance running, which is suitable for cycling.

3). Effect of the invention The so-called drop handle has a new fourth grip, so it bends forward and pedals in a natural state, so there is less fatigue even during long distances such as cycling, and The force to kick the pedal is more stable than the conventional kick while holding the drop part, so it is easier to put more force on the pedal and speed is also increased. Furthermore,
Even when used for triathlon, the center of gravity is lowered due to the fourth grip, there is no danger of plunging from the head even when a brake is applied, and because the brake is close, braking is easy. . In addition, when the vehicle is traveling at high speed, the arm can be brought to the fourth grip portion in a natural manner, which makes it easy to operate the steering wheel suddenly and is extremely safe.
