Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a roof carrier developed with the intention of being applied not only to conventional automobiles but also, in particular, to pressed door type passenger cars.

(Prior Art) As is well known, this type of roof carrier has a means for placing a roof channel, which serves as a luggage platform, on the roof of the vehicle body via supporting legs, and fixing these supporting legs to the roof edge with a hook. It had been taken.

A drain rail is installed on the roof edge of a conventional automobile, and the fixing means has a hook-shaped metal fitting that holds the rail from the side.

(Problem to be Solved by the Invention) Recently, press-door type door opening/closing mechanisms have been adopted in automobiles, and the conventional bulky latch fittings become an obstacle to the door outer extending toward the roof, so they cannot be used as they are. It became unusable. In addition, with this type of press door type drain rail, the amount of rise of the roof edge from the inclined surface is small, and the raised rail member is equipped with a rubber damper to ensure close contact with the outer door of the door being closed. However, there is a problem in that the latching fitting that holds the damper easily comes off. In particular, in the case of a structure in which a flexible metal band is attached to the tip of the latching member as an intermediate connecting member, this latching member is used for rotation around the connection between the rigid latching member and the band. It works very well, so it is extremely easy to come off.

On the other hand, if the hook-shaped tip of the latching fitting is configured to have an acute angle in consideration of the biting force of the latching fitting against the rubber damper or the rotational force acting on this fitting, the tip of the fitting will bite into the rubber damper too strongly locally. There is a risk that cracks will occur there, so this configuration is difficult to adopt.

Therefore, it is an object of the present invention to solve the problems with the above-mentioned latching fittings and to provide a roof carrier having a characteristic latching structure that can be used not only in conventional roof edge structures but also in pressed door type roof edge structures. This is the purpose.

(Means for Solving the Problems) In order to achieve the above object, the gist of the present invention is as follows. Note that reference symbols used in the examples are shown in parentheses.

The present invention is based on an automobile roof carrier in which the tip end latching portion 4 of the coupling device 5 is latched and fixed to the roof edge 10 of the vehicle body via the tightening bolt 3 screwed onto the frame channel support leg 1. . On such a premise, the connector 5 is a metal piece having a hook portion 4 and a pressure contact portion 8B at the free end of the tightening bolt at one end and the opposite end, respectively,
A sliding surface 8A is provided between the hooking portion 4 and the pressure contact portion 8B.
is provided, and this surface 8A is slid on the guide surface 7 fixed to the support leg side with a required guide angle,
When the bolt 3 is rotated, the connecting tool 5 is connected to the pressure contact portion 8B.
It is a feature of the present invention that the roof edge can be latched onto the roof edge by being pressed and moving according to the guide angle.

(Function) In the roof carrier according to the present invention, when the tightening bolt is rotated, the connector is pressed, and its sliding surface moves on the guide surface at the required guide angle on the support leg side. If this guide angle is set in the direction in which the coupling device rises relative to the horizontal plane, and the direction of movement is set in the direction toward the inside of the vehicle width, the coupling device will be able to be pulled diagonally upward by placing the hook under the roof edge. force can be applied to. The direction of this force can be regulated by the guide angle.

Preferred embodiments of the automotive roof carrier of the present invention which operate in this manner will be described in detail below.

(Example) Fig. 1 is a side view showing the main part configuration of the automobile roof carrier according to the present invention, in which a tightening bolt 3 having a threaded shaft 2 is attached from the outside to the right edge of the leg 1 supporting the frame channel. It is screwed on.

On the other hand, a connector 5 having an inverted L-shaped hook portion 4 at its tip and an L-shaped free end 8 at the opposite end has its L-shaped free end 8 attached to the end surface of the leg 1. Insert it into the inside of the leg 1 through the window 6 (see Figure 2). The sliding surface 8A provided on the free end 8 is supported on the guide surface 7 fixed to the leg 1 at a required angle upward to the left with respect to the left and right horizontal direction, and the pressure contact portion 8B erected on the free end 8 is provided with the screw. The free end of the shaft 2 is pressed against it.

On the other hand, the hooking portion 4 has its hooking end 4a attached to the rubber damper 1 attached to the rail member 9 of the roof edge.
Place it on the lower side of 0, rubber damper 10 if necessary.
The connecting tool 5, which is attached by cutting out a part of the press door 11, is formed into an appropriately bent shape so as not to interfere with the opening and closing of the press door 11. Additionally, a cushioning pad 12 is interposed between the roof 13 and the leg 1.

Assuming a normal line B to the contact point A of the latching surface of the latching end 4a that abuts the damper 10 at the contact point Q, the sliding surface 8A of the connector 5 supported by the guide surface 7 and the pressure contact portion 8B The intersection point P with the normal line B is located inside the vehicle body.

Furthermore, when the tightening bolt 3 is rotated and the free end of the bolt slides and moves the pressure contact part 8B on the guide surface 7 to the left in FIG. 1, the locking end 4a also moves at the angle of the guide surface. , is pressed against the rubber damper 10 from diagonally downward. In the installation state shown in the figure in which the connector 5, which is hooked at one end, is sufficiently tensioned, at the intersection point P there is a force that pulls the connector 5 diagonally upward, and a force in the direction of the line of action C that presses the roof carrier against the roof 13. It's working. Note that at this time, the lower end of the edge member 1A of the support leg 1 is in contact with the connector 5 from above,
The counterclockwise rotation of the hook 4 about the intersection point P is suppressed (see FIG. 2).

In addition, in addition to being a flat surface, the retaining surface of the retaining portion 4 may be configured to have a gentle curved surface on both sides with the normal line B as the center line, so that the rubber damper 1
0 becomes reliable, and is effective in preventing the hooking part 4 from coming off.

(Effects of the Invention) In the automobile roof carrier of the present invention, the latching fitting and the connecting body, which were conventionally separated, are integrated as the connecting fitting 5 made of, for example, a highly rigid metal piece,
One end thereof is a hooking part 4 to the roof edge, and the opposite end thereof is a pressure contact part 8 for tightening the bolt 3.
The free end 8 consists of a sliding surface 8A and a sliding surface 8A. Since this sliding surface 8A is configured to slide on the guide surface 7 on the support leg side that has a required angle with respect to the horizontal plane, the direction in which the connector 5 is latched to the roof edge can be regulated by this angle. can.
Even if the roof edge rubber damper 10 is of the type that is hidden behind the door outer and is thin, the roof carrier can be attached to the roof by regulating the hooking direction of the connector 5 so that it faces diagonally upward from the bottom. 13 can be securely fixed. The locking direction of the connector 5 is not affected by the inclination angle of the roof 13.
