Description

  The present invention relates to a mounting structure for a bicycle auxiliary part for attaching an auxiliary part such as a forehead to the front of a handle via a mounting tool, and a bicycle including the same.

  Generally, on the rear wheel of a bicycle, a loading platform for placing luggage is provided. However, in the case of a folding bicycle or a sports bicycle, the loading platform is handled for reasons such as loss of design. In many cases, it is installed in front of the door via a fixture.

  In addition, since the luggage storage capacity is small with only the loading platform, there is a commercially available one in which a forehead or the like is further installed in front of the handle via an attachment.

  As described above, the front wing and the loading platform (hereinafter referred to as “auxiliary parts”) are installed in front of the handle via the fixture.

  However, the mounting tool for installing the auxiliary component is fixed to the handle boss or the like at the tip of the frame that penetrates the handle or the handle shaft by hooking or clamping one end of the metal stay. The auxiliary component is attached to the other end of the lens (for example, see Patent Document 1).

However, the conventional bicycle auxiliary component mounting structure has the following problems.
First, there was a problem that it was weak in strength.

  That is, as described above, the fixture for installing the auxiliary component is fixed to the handle boss or the like in front of the frame passing through the handle or the handle shaft by hooking or sandwiching one end of the metal stay, Since the auxiliary component is mounted on the other end of the metal stay, the entire load of the auxiliary component is applied to the metal stay.

  In addition, a two-wheeled vehicle such as a bicycle is more likely to fall than a four-wheeled vehicle, and often receives impacts from the auxiliary parts.

  Therefore, when these loads and impacts are applied to the metal stay, the metal stay is deformed and there is a problem that its strength is weak.

Next, there was a problem that the steering of the steering wheel was bad and dangerous.
In particular, in a structure in which the mounting tool is mounted on the handle and the auxiliary component is mounted, the entire load of the auxiliary component is applied to the handle via the mounting tool, and thus steering of the handle becomes heavy. As a result, the steering performance is poor and there is a problem that it is dangerous.

  In addition, if the auxiliary parts are attached to the steering wheel, the position of the center of gravity of the bicycle becomes high, and the driving tends to become unstable and dangerous. Therefore, the auxiliary parts should be installed as close to the ground as possible. It is requested.

Furthermore, there was a problem that the design was poor.
That is, the auxiliary parts are literally auxiliary parts that are installed as optional items for bicycles, but there are a variety of designs for the auxiliary parts.

  However, the mounting tool for mounting the auxiliary component has hardly been developed, and therefore there is a problem that the mounting tool and the bicycle are not integrated and the design is poor.
