DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a fastening device of the type described in the preamble of claim 1.
In a conventional fastening device of this type (German Utility Model No. 78 07 135), a protecting cap is pivotably or removably secured to the clamping claw and is connectable with the clamping claw by the locking bolt of a lock secured to the protecting cap to the extent that, in the locking position of the lock, the locking bolt extends into a slot of the clamping claw so that, without actuating the lock, the protecting cap cannot be detached any more. In this manner, the tensioning screw which biases the clamping claw against the roof gutter and against the supporting foot is not accessible any more, i.e., the supporting foot can be secured to the roof gutter of an automative vehicle in a theftproof manner.
A drawback of this conventional construction is that, in order to allow for actuation of the tensioning screw, the protecting cap must be detached and then constitutes a part which is separated from the clamping claw and must be applied again subsequent to securing of the supporting bracket on the roof gutter. This is not only cumbersome but there also exists the possibility of the protecting cap becoming lost if it is not attached to the clamping claw when the supporting bracket is removed.
OBJECTS AND SUMMARY OF THE INVENTION
An object of the invention is to overcome such drawbacks and to provide a fastening device wherein the actuation is facilitated and losing of the protecting cap is impossible.
In accordance with the invention, this object is accomplished in that the protecting cap is non-separably connected with the clamping claw, at least from the outside, and is provided with a mounting aperture and in that the locking or blocking device closes the mounting aperture in the locking position thereof. As a result of connection of the protecting cap to the clamping claw in such a way that, at the very most, the protecting cap can be detached only from the inside, i.e., when the supporting bracket or the luggage rack is removed from the roof gutter, and further in view of the fact that a mounting aperture is provided in the protecting cap, one ensures that unlocking of the locking device merely entails exposure of the mounting aperture in order to be in a position to actuate the tensioning screw. Removal of the protecting cap is not necessary. This renders it impossible to misplace the protecting cap and to be incapable of locating it again, when necessary, while the supporting bracket or the luggage rack is removed.
In accordance with a preferred embodiment of the invention, the locking or blocking device comprises a lock which is disposed adjacent to the mounting aperture and has a portion, such as a locking bolt, which overlies the mounting opening from the inside in the locking position thereof.
The protecting cap can be welded or riveted to the clamping claw but it is also possible, in principle, to separably secure the protecting cap to the clamping claw. For such purpose, one end of the protecting cap comprises a bent-over tongue which can be introduced into a slot of the clamping claw and the opposite end of the protecting cap is provided with an inwardly bent portion or lug which is connectable with the clamping claw from the inner side of the latter by a screw connection. Owing to the last-discussed construction, there exists, broadly speaking, the possibility of separating the protecting cap from the clamping claw; however, only in the event that the supporting bracket or the luggage rack is not installed on the roof of the vehicle. In normal condition of use of the supporting bracket or luggage rack, the screw connection is covered by the clamping claw on the one hand and the supporting foot on the other hand so that the protecting cap cannot be removed.
In order to accomplish the previously mentioned object, the protecting cap, too, can be separably but articulately connected with a base plate or an analogous holder which can be fixed on the clamping claw by
