Description

[Detailed description of the invention] The present invention is a structure for attaching an object to a bicycle. Specifically, the both ends of the handlebar fixed to the handlebar stem are raised upwards, and the object to be attached, such as a basket, is placed between these raised ends. The present invention relates to a structure for attaching an object to a bicycle, such as a basket, in which the object is supported by the handle stem.

Generally, in the above-mentioned structure for attaching an object such as a basket to a bicycle, the object is directly supported on the handlebar stem, so the object and the front fork are rigidly connected. Therefore, while driving, vibrations caused by unevenness of the road surface are directly transmitted to the attached object via the handle stem, and this vibration causes the attached object, such as a shopping bag, to be transmitted directly to the attached object. If a shopping cart is attached, the purchased items stored in the shopping cart may be damaged, or if a child's chair is attached as an attached object, the child placed in the chair may feel uncomfortable. It was hot.

The present invention was devised in view of these problems, and its purpose is to elastically hold an attached object, such as a basket, against the handlebar stem to prevent the bicycle from vibrating due to uneven road surfaces. However, the structure for attaching items such as baskets to bicycles is designed to prevent damage to purchased items stored in the item and to prevent discomfort to children placed on the item. It is in the point of providing.

That is, in the present invention, both ends of the handlebar fixed to the bar holding part of the handle stem which is rotatably attached to the head pipe are raised upward, and an object to be attached such as a basket is interposed between the raised parts. The mounting structure for an object to be mounted is such that the object to be mounted is supported on the handle stem, and the object to be mounted is provided with a holder that slidably guides the object to be mounted relative to the rising part. An attached object is supported on the upright part so as to be movable up and down, and on the top surface of the handle stem,
Further, a flat receiving surface is provided at the center of rotation of the stem, an elastic member is interposed between the receiving surface and the object to be mounted, and the object to be mounted is elastically held on the stem. It is characterized by:

The handle stem is fixed to the front fork 2 by disposing it above the upper bearing 7 which is screwed into the handlebar stem, and by further tightening the expander bolt 5, the lifting foot 6 is moved upward in the vertical direction. be. Further, the handle stem 4 is provided with a bar holding hole 10 that passes through the bar holding portion 4a of the handle stem 4 in the horizontal direction.
Attachment holes 11, 11 are vertically drilled on the lower surface side of a, and the handle stem 4 is divided vertically from the bar holding hole 10 portion, and the handlebar 3 held in the bar holding hole 10 is Mounting hole 1
It is fixed by tightening the tightening screws 12, 12 inserted into the holes 1, 11. Further, as described above, both ends of the handlebar 3 fixed to the handlebar stem 4 are raised upward, and an object A such as a basket is interposed between the raised portions 3a, and the object A is mounted on the handlebar stem 4. It is made to be supported by the stem 4.

In the mounting structure for the mounted object A configured as described above, the mounted object A is provided with a holder 13 that slidably guides the mounted object A to the upright portion 3a.
is provided to support the mounted object A on the upright portion 3a in a vertically movable manner, and interpose an elastic member 14 between the mounted object A and the handle stem 4,
The attached object A is elastically held on the handle stem 4.

Specifically, a holder 13 that slidably guides the object A to the upright portion is made of steel or hard rubber, and the holder 13 is attached to both left and right sides of the object A. The mounted object A is supported on the upright portion 3a so as to be movable up and down.

Further, elastic members 14, 14 are provided at the bottom of the object A, the top surface of the handle stem 4, and at and near the center of rotation of the handle stem.
is interposed therebetween, and the object to be mounted A is elastically held on the handle stem 4.

Note that the mounted object A has a basket portion 15 in front of it.
A child's chair part 16 is formed at the rear of the child's chair part 16. Footrests 17 are provided on both left and right sides of the child's chair part 16, and a handle 18 is provided at the rear of the chair part 16.

The present invention is constructed as described above, and the mounted object A is attached to the handlebar 3 by the holder 13.
The mounted object A is vertically movably supported between the raised parts 3a of the handlebar stem 4, and is held by elastic members 14, 14 interposed between the mounted object A and the handle stem 4. The elastic member 14,1
Along with the elastic deformation of 4, it becomes possible to move vertically along the raised portion 3a.

However, when the mounted object A is used to store purchased items or to ride with a child on board, even if the road surface is uneven and the bicycle vibrates due to the unevenness of the road surface, the above-mentioned Since the mounted object A is elastically held by the elastic member 14, the vibration is not directly transmitted to the mounted object A via the handlebar 3 or the handle stem 4. Since the attached object A can be held in an extremely stable state by the elastic deformation of the elastic members 14, 14, even if the bicycle vibrates due to unevenness of the road surface, the basket of the attached object A can be held. If the purchased items stored in section 15 are damaged or
Moreover, the possibility of causing discomfort to the child placed on the child chair portion 16 of the object A is reliably eliminated.

As shown in FIG. 3, the attached object A can be supported near the center of rotation of the handle stem 4, so when the attached object A is used to store purchased items or carry a child. However, it goes without saying that it can prevent unbalanced loads from acting on the handlebars and improve the stability of the bicycle.

Further, although two elastic members 14 are used in the embodiment, one or three or more elastic members 14 may be used.

As explained above, the present invention involves raising both ends of the handlebar, which is fixed to the bar holding part of the handle stem which is rotatably attached to the head pipe, upward.
A mounting structure for mounting an object such as a basket between the raised parts and supporting the object on the handle stem, wherein the object is attached to the object to be mounted. A holder is provided to slidably guide the object to the upright part, and the object to be mounted is supported on the upright part so as to be movable up and down. A flat receiving surface is provided on the mounting surface, an elastic member is interposed between the receiving surface and the object to be mounted, and the object to be mounted is elastically held on the stem. Even if the bicycle vibrates due to the unevenness caused by storing the bicycle or carrying a child on it while riding on an uneven road surface, this vibration can be absorbed, and even when turning, there is no unbalanced load on the handlebar device. This prevents the steering wheel from becoming loose or becoming heavy when turning, and as a result, the bicycle can be run stably and nimblely. Furthermore, the vibrations are not directly transmitted to the object to be worn, so there is no risk of damaging purchased items stored in the object or causing discomfort to the child placed on the object. This will surely eliminate the risk of such damage.
