DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof carrier attachment for fixing a carrier member to a luggage mounting rail of an automobile roof.

[0002]

2. Description of the Related Art Conventionally, there has been known a fixture for fixing a carrier member for mounting luggage such as skis on a roof of an automobile such as a passenger car. For example, JP-A-8-25
No. 3080 discloses a mounting for fixing a ski carrier to a substantially horizontally extending roof rail.

[0003]

When the roof rails extend horizontally, the carrier members disposed at the front and rear of the vehicle can be easily connected to each other without the height adjusting function. Therefore, it is easy to load luggage such as skis, and the loaded luggage has good stability. However, when the roof rail is not horizontal but forms an arc in the vertical direction, it is difficult to arrange a plurality of carrier members whose height cannot be adjusted so as to be horizontal to each other. This is because each carrier member is inclined following the arc of the roof rail.

Accordingly, an object of the present invention is to make it easy to attach a carrier member horizontally to a roof rail even if the roof rail forms an arc.

[0005]

In order to solve the above-mentioned problems, the present invention is based on a carrier mounting device for fixing a carrier to a luggage mounting rail of an automobile roof.

On this premise, the present invention is characterized in that the mounting member can contact the first member fixed to the carrier member and the upper surface and the lower surface in the radial direction of the rail. Wherein a second member and a third member are attached to the first member so as to be swingable in the longitudinal direction of the rail, and at least one of the second and third members is formed by the second and third members. The rail is formed so as to be substantially movable in the radial direction above and below the rail so that the member can press the rail from the radial direction.
