As shown in FIGS. 13 to 15, a conventional ski carrier of this type is magnetically attracted to a roof R of an automobile A and has a retaining portion 1A for removal formed at an appropriate position on an outer peripheral edge portion thereof. The magnetic base part 1 is provided with a base 1, and a pedestal 2 formed in a semi-cylindrical shape is integrally connected to a central portion of an upper surface of the magnetic base 1. A ski receiving board 5 is rotatably and vertically movable via a pair of left and right pedestals 4 and 4 which rotate in the front-rear direction of the vehicle body, and is attached to the ski receiving board 5 in a standing posture. When the ski plate 6 is fitted and installed in the pair of left and right ski fitting grooves 5A, 5A, the ski receiving plate 5 is lowered mainly by the load of the ski plate 6 to maintain the standing posture of the ski receiving plate 5. To ensure that the skis By solving the engaging state like the board 5 by pulling operation, so that it is possible to fall down the ski 受盤 5.

However, in the conventional ski carrier, the ski plate 6 is attached to the ski receiving plate 5 after the ski plate 6 is fitted in the ski fitting grooves 5A and 5A. (Omitted) is appropriately wound, and the ski plate 6 is removed by unwinding the rubber band. Therefore, the work of attaching and detaching the ski plate 6 is troublesome and the workability of attaching and detaching is poor. Further, with the means for holding the attachment state of the ski plate 6 by the rubber band, the attachment state can be easily released by a third party, so that the ski plate 6 can be released.
Have a risk of being stolen. On the other hand, when the ski carrier is not used, in order to remove the ski carrier from the roof R of the automobile A, a finger is hooked on the disengagement hooking portion 1A and pulled up, and the pulling operation is performed. Continue to
This is done by gradually reducing the adsorption area of the magnetic base portion 1 with respect to the frame R. However, in the conventional ski carrier, since the retaining portion 1A for removal is left in an exposed state, it can be easily removed from the roof R by a third person, and therefore the ski carrier itself. There is a risk of being stolen. That is, in the conventional ski carrier, since no anti-theft measures are taken, not only the ski plate 6 but also the ski carrier may be stolen, and the safety is low. ing.

Therefore, as shown in FIGS. 1 and 2, the magnetic base portion 1 is covered from above with a resin cover member 7 having a relatively high flexibility, and the magnetic base portion 1 is covered with a central portion or The vicinity thereof is integrally connected to the cover member 7, and the cover member 7
The hook portion 1A for removal is concealed by the auxiliary cover 8 which is openably and closably attached to the cover member 7, and a first locking mechanism (not shown) for holding the closed state of the auxiliary cover 8 is provided between the cover member 7 and the auxiliary cover 8. ) Is provided, the first lock mechanism is configured to be unlocked by a dedicated key, and has a fixed member 9A located on the lower side and a movable member 9B located on the upper side. The base end of 9B is a horizontal pin 9C.

Therefore, the safety can be improved, and the conventional drawbacks can be solved. However, in this type of ski carrier, the magnetic base 1 and the cover are covered.
As described above, the member 7 and the member 7 are integrally joined only in the central portion or in the vicinity thereof, that is, as shown in FIG. 3, a plurality of magnetic base portions 1 and cover members 7 are provided in the vicinity of the central portion. Screw 10 (However, in Fig. 3, one screw 1
(Only 0 is shown), the magnetic base 1 is attached to the roof R of the automobile A shown in FIG. F R
However, the curvature of the magnetic base portion 1 is not transmitted to the peripheral side of the cover member 7, and the cover member 7 is left in its original shape. ,
A gap 11 is formed between the peripheral portion of the cover member 7 and the peripheral portion of the magnetic base portion 1, and the peripheral portion of the magnetic base portion 1 is mounted on the roof R while being exposed. Therefore, the appearance of the ski carrier during use is reduced, the air resistance during running of the vehicle is increased, and the negative pressure generated by the air flowing on the upper surface of the cover member 7 and the lower surface of the cover member 7 from the gap 11 are caused. There is also a risk that the ski carrier will fall off due to the lift generated by the cooperation with the air pressure that is caught and applied to the cover member 7.

In order to prevent such inconvenience, FIG.
As shown in FIG. 5, the magnetic base portion 1 and the cover member 7 are integrally connected by a plurality of screws 10 (however, only one screw 10 is shown in FIG. 5) in the vicinity of the central portion thereof. In addition, a structure in which the peripheral edge side is integrally connected by a plurality of screws 12 (however, only one screw 12 is shown in FIG. 5) can be considered.

The problem to be solved is to simplify the work of attaching / detaching the ski plate to improve the workability of attaching / detaching it and to take anti-theft measures. If it is attempted to prevent the carrier from being stolen and improve safety, the appearance of the ski carrier during use may be deteriorated, or the ski carrier may be dropped due to increased air resistance when the vehicle is running. There are various points such as reducing the size to make it unusable.

[0008]

According to the present invention, a magnetic base part that is magnetically attracted to an upper surface of a roof of an automobile and a magnetic base part that covers the magnetic base part from above and a central part or its vicinity is integrally coupled to the magnetic base part. A ski carrier having a cover member and a ski holding portion integrally coupled to the upper part of the cover member, wherein a plurality of first couplings having locking portions formed at appropriate positions on the peripheral side of the magnetic base portion are provided. A plurality of bosses that are provided with members, cutouts are formed in the locking portions of each of the first connecting members, and are inserted into the cutouts when the magnetic base portion and the cover member are integrally coupled, and the lower ends of these bosses. And a second connecting member that is provided continuously with the boss portion and that has an interference portion that extends outside the diameter of the boss portion is provided so as to extend downward from the lower surface of the cover member, and between the inner edge of the cutout portion and the outer edge of the boss portion.
Clearance is formed on the ski carrier, which improves the workability of attaching and detaching the ski, and reliably prevents the ski and the ski carrier from being stolen. We achieved the objectives of avoiding deterioration of appearance, dropout due to increase of air resistance during vehicle running, and reduction of contact area with roof.

[0009]

According to the present invention, a clearance is provided between the first connecting member and the second connecting member connecting the magnetic base portion and the peripheral side of the cover member to each other. For this purpose, the magnetic base portion and an integral joint portion at or near the central portion of the cover member, the integral joint portion by the first coupling member and the second coupling member, and the cover existing between the integral joint portion and the integral joint portion. -Magnetic magnetic flux existing between the member and the integral connecting portion and the integral connecting portion.
The space does not form a series of closed cross-section structures. That is, the flexibility of the cover member is preserved. Moreover, the relative movement of the first connecting member and the second connecting member can be absorbed by the clearance. Therefore, in use, when the peripheral side of the magnetic base portion is curved along the curved surface of the roof and evenly adheres thereto, this curvature changes from the engaging portion of the first connecting member to the second connecting member. The cover member is transmitted to the interference portion, and due to its own flexibility, the cover member bends following the bending of the magnetic base portion. Therefore, the conventional gap is not formed between the peripheral edge of the cover member and the peripheral edge of the magnetic base. That is, even if the radius of curvature of the roof curved surface varies depending on the vehicle type, the ski carrier can be mounted on the roof without exposing the peripheral portion of the magnetic base portion.
