JP6898130B2 - Carrier device for bicycles - Google Patents

Description

The present invention relates to a carrier device used for mounting a bicycle in a luggage compartment or the like in a vehicle.

In recent years, it has been required that a bicycle can be easily loaded and unloaded in the luggage compartment of an automobile when a bicycle is loaded in the luggage compartment of the automobile when going out for leisure or the like, or when a child is sent and received together with the bicycle.
Various carrier devices have been proposed because the bicycle tends to fall over when the bicycle is mounted on the rear floor of a wagon type, box type, van type, etc.
For example, Patent Document 1 discloses a bicycle mounting device that can be mounted while rotating the front wheels of a bicycle on a guide rail and a control rail.
However, since it is necessary to arrange two guide rails and control rails side by side in the luggage compartment, there is a problem that the mounting space becomes wide.
In addition, it is difficult to bend the control rail with respect to the guide rail.
