Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle carrier, and more particularly to a bicycle carrier for mounting a bicycle on a base carrier provided on a roof of an automobile.

[0002]

2. Description of the Related Art Bicycle frames have been diversified in shape, and in recent years, it is not unusual to use an aluminum thick frame or an aluminum or carbon irregular frame. When trying to load a bicycle of this type on a vehicle carrier, the type of carrier that is currently common is to hold the down tube by fixing the bicycle tire on the rail and holding the down tube. In some cases, loading may not be possible due to excessive force in the structure of the part to be loaded. When such a bicycle is loaded on a carrier, the bicycle is inverted and mounted on a carrier of a type in which a steering wheel and a saddle are fixed (inverted type), or a tire mounting portion of a front fork after removing a front tire. And a carrier (fork-down type) in which a part of the frame or the rear tire is fixed and loaded.

[0003]

However, the above-mentioned inverted type and fork-down type carriers are cumbersome for loading work and are not very common at present. In other words, in the type in which the handlebar and saddle are fixed by turning the bicycle upside down, the so-called sports cycle can be almost loaded. Or there is a problem that it is easily soiled. Furthermore, although there is almost no problem in the case of a sports type bicycle, there is also a problem that the handle of a general family cycle often cannot be loaded because the shape of the holder does not match.

Further, as shown in Japanese Utility Model Laid-Open Publication No. 6-71312, a type in which a tire mounting portion of a front fork and a part of a frame or a rear tire are fixed and loaded after removing a front tire of a bicycle, The stability when running with a bicycle loaded on the carrier is good, but when removing the front tire, you must first loosen the front brake wire, then loosen the lever or nut on the front tire mounting part, and then remove the tire, In addition, the removed front tire must be carried separately from the bicycle body, and if the removed front tire is loaded on a bicycle carrier, the extra space on the carrier will be used accordingly It is impossible to load bicycles efficiently in limited space .

The present invention has been made to eliminate the above disadvantages.

[0006]
