Description

The present invention relates to a structure for fixing a roof box to a cross bar provided on a roof of a vehicle.

Conventionally, there are many structures for fixing a roof box to a crossbar provided on the roof of the vehicle, but in recent years the shape and size of the crossbar provided on the roof of the vehicle, which is the object to be fixed to the roof box, are different. There is a tendency to diversify, and compatibility (general versatility) with various types of crossbars is required.

In addition, the increase in the number of roof boxes with large luggage storage capacity in the left-right direction (the same direction as the left-right direction of the vehicle) and the increase in vehicles with high vehicle height due to the increase in minivan type vehicles The fixing work is difficult.

For example, as shown in FIG. 22, the conventional structure for fixing the roof box 1 to the general crossbar 2 has a substantially U-shape having a contact portion with the lower surface of the crossbar 2 and having screw portions at both ends. A roof box fixing mechanism has a known arm member 3, a hole provided in the bottom portion 1 of the roof box through which the arm member 3 can be inserted, and nuts 41 for tightening screw portions provided at both ends of the arm member. It is.

However, in the above-described prior art, the roof box 1 is fixed at a position where the substantially central portion of the arm member 3 and the lower surface of the crossbar 2 can be brought into contact with each other. It is necessary to fasten and fix the above threaded portion from the inside of the roof box with the nut 41 while maintaining the state in which the threaded portion of the roof is projected from the hole provided at the bottom of the roof box to the inner surface of the roof box. The roof box 1 is fixed to the bar 2 at four positions (front left, front right, rear left, rear right) in the left and right direction and the front and rear direction of the roof box (the same direction as the front and rear direction of the vehicle). In an open roof box, the arm member 3 can be lifted and lifted by one person to fix the opposite side of the opening side (right side for left opening and left side for right opening). In order to maintain the screw parts at both ends of the rubber member protruding from the inner surface of the roof box, it is necessary to devise such as temporarily fixing the arm member 3 to the cross bar 2 with an adhesive tape or the like. When the operator touches the roof box, the position of the roof box 1 moves with respect to the cross bar 2, so that the adhesive tape of the arm member is peeled off from the cross bar 2, and the arm member is placed on the roof of the vehicle. 3 could fall and scratch the roof.

In addition, even when the adhesive tape of the arm member 3 is not peeled off from the cross bar, the arm member 3 is lifted from below the bottom of the roof box between the bottom of the roof box and the roof, and the screw portions at both ends are The operation of tightening the screw portion with the nut 41 from the inside of the roof box while maintaining the state of projecting from the hole provided at the bottom of the roof box to the inner surface of the roof box is to inadvertently slide the hand from the arm member 3. The car roof could be scratched.

Further, in order to solve the above problems, as shown in WO2006 / 007813A1 and US2004 / 0155081A1, a fixing mechanism for the roof box in which the arm member 42 and the arm member tightening mechanism 43 are arranged in advance on the bottom surface of the roof box. Is known.

However, since these operating mechanisms have complicated operation structures, it is necessary to form the arm member 42 by die-casting or injection molding, and any arm member 42 holds the crossbar 2 at the free end. Due to the structure (cantilever structure), it is necessary to make the absolute strength of the position of the base much stronger than the both-end support structure, so the parts are larger and the number of parts is larger, so the cost is very high. There are drawbacks.

Further, since the complicated structure forms a projection 45 (cross bar receiving portion) at the bottom bottom 44 of the roof box, when fixing the roof box having the fixing mechanism to the cross bar, as shown in FIG. In addition, in the fixing mechanism disclosed in WO2006 / 007813A1, the fixing mechanism is fixed in advance according to the position of the crossbar 2, and the protrusion 45 (the receiving portion of the crossbar) and the arm member 42 protruding downward are crossbars. The roof box is moved horizontally while lifting the entire bottom position of the roof box sufficiently higher than the top position of the cross bar so that it does not hit the roof. It was very difficult for one person to fix the roof box to the crossbar because it was necessary to place it on top.

Further, as shown in FIG. 24, in the fixing structure shown in US2004 / 0155081A1, it is not always necessary to fix the fixing mechanisms to the position of the crossbar 2 in advance. When not fixing according to the position of each, the fixing mechanism is arranged in advance at a position avoiding the appropriate position, and the roof box 1 is sufficiently lifted with the roof box 1 placed on the appropriate position on the cross bar 2. However, it is necessary to move each fixing mechanism to the position of the crossbar 2, and it is not easy to fix the roof box 1 to the crossbar 2.
