Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention is a bar end cap for a handlebar, more specifically, it has an insertion part that fits into the bar end of a bicycle handlebar, and a closing part that closes the bar end. Regarding the end cap.

(Prior Art) Conventionally, as shown in Japanese Utility Model Application Publication No. 54-119153, the surface of the closing part in this type of cap is parallel to the plane perpendicular to the center line of the insertion part. It has become.

(Problem to be solved by the invention) Therefore, especially when attached to a drop handlebar with a downwardly curved grip, when a rider sitting on a bicycle saddle moves his/her legs and depresses the pedals, When pedaling, the driver's knees could hit the closure surface of the cap.

The present invention has been devised in view of the above points, and the purpose is to provide a guide surface on the surface of the closing part so that when pedaling,
While making it difficult for the knee to hit the closure surface,
The knee can be guided inward in the width direction of the bicycle with respect to the rotation plane of the crank arm, and even if the knee hits the surface of the closure part, part of the contact force acting on the knee is prevented. The part is released in the direction of the inclination of the guide surface, so that the impact caused by contact can be alleviated.

(Means for Solving the Problems) Accordingly, the present invention provides an end cap having an insertion part 1 that is inserted into a bar end of a handle, and a closing part 2 that closes the bar end, On the surface of part 2,
A guide surface 3 is provided on a plane perpendicular to the center line of the insertion portion 1, which slopes from the outside in the width direction of the bicycle toward the front in the front and back direction of the bicycle.

(Function) When the driver seated on the saddle pedals, since the guide surface 3 is on the surface of the closure part 2, the knees are unlikely to hit the surface of the closure part 2, and the knees are not easily touched. It can be guided inward in the width direction of the bicycle with respect to the rotation plane of the crank arm, and when the knee hits the surface of the closure part 2, a part of the contact force acting on the knee is transferred to the guide surface. 3 in the direction of inclination, so that the impact caused by the contact can be alleviated.

(Embodiment) In the embodiment shown in FIG. 1, the closing portion of the end cap A has a cylindrical insertion portion 1 that fits into the bar end of the handle H, and a closing portion 2 that closes the bar end. 2, from the outer side in the width direction of the bicycle to the inner side (direction of arrow X in the figure) with respect to the surface perpendicular to the center line of the insertion part 1, and the front of the bicycle in the front and back direction (direction of arrow Y in the figure). The guide surface 3 is provided with a slope.

The cap A is mainly made of a relatively light hard material such as hard synthetic resin or aluminum, and there is a step between the fitting part 1 and the closing part 2. A bar tape wrapping part 4 is provided which has a larger diameter than the insertion part 1 and has the same diameter S as the outer diameter of the handle H.

Further, the cap A may be formed not only hollow but also solid.

The cap constructed as described above is mainly attached to the inside of the drop handle whose grip portion is curved downward as shown in FIG.

This installation is done by inserting the insertion part 1 into the bar end,
A bar tape T to be wrapped around the handle H is wound around the outer periphery of the bar tape winding part 4 following the insertion part 1, and is fixed to the handle H.

Therefore, when a driver seated on the saddle pedals, his/her knees are bent toward the closed portion 3 by the amount that the guide surface 3 is inclined.
Also, since the knee can be guided inward in the width direction of the bicycle with respect to the rotation plane of the crank arm along the guide surface 3, the knee can be guided inward in the width direction of the bicycle with respect to the rotation plane of the crank arm. On the other hand, you can pedal with it slightly closed, making it easier to pedal.

Moreover, even if the knee hits the surface of the closure part during the pedaling, a part of the contact force acting on the knee can be released in the direction of the inclination of the guide surface 3, so that the impact caused by the contact can be alleviated. It is.

Further, since the bar tape winding portion 4 has the same diameter S as the outer diameter of the handle H, the bar tape T can be tightly wound without being inflated.

Therefore, inadvertent twisting of the bar tape T wound around the bar tape winding part 4 can be eliminated, and the bar tape T can be firmly fixed.

In addition, by providing the bar tape wrapping part 4 separately from the insertion part 1 into the bar end, the length of the handle H can be shortened by the length corresponding to the wrapping part 4, so the cost of the handle H can be reduced. In addition, the handle H can be made lighter.

That is, the handle H needs to be made of a rigid and expensive metal material such as stainless steel, whereas the cap can be made of, for example, hard synthetic resin, which is lightweight and relatively inexpensive. The cost in terms of materials can be reduced, and the weight can also be reduced.

(Effects of the invention) As described above, the present invention has a surface of the closing part 2 that closes the bar end. Since the guide surface 3 is provided so that the guide surface 3 slopes forward in the longitudinal direction of the bicycle, when the rider pedals, especially when the bicycle is attached to a drop handlebar with a downwardly curved grip portion,
Not only does the rider's knee not easily hit the surface of the closure part 2, but the rider's knee can be guided inward in the width direction of the bicycle with respect to the rotational plane of the crank arm along the guide surface 3, making it easier to pedal. It is.

Furthermore, even if the knee hits the surface of the closure part 2 during pedaling, a part of the contact force acting on the knee is transferred to the guide surface 3.
It is possible to relieve the impact caused by contact by releasing it in the direction of inclination.
