Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roof carrier for use in vehicles such as automobiles in general, and particularly for mounting on the roof of an automobile.

As a roof carrier installed on the cargo bed or roof of a vehicle to store long ski equipment, camping equipment, or regular luggage that cannot be stored inside a car, etc. For example, rain gutters installed along the roof, such as the vehicle cargo platform device described in JP-A-62-68154 and the vehicle luggage carrier described in JP-A-58-185342, are used. Types that can be used and attached to this are widely used and are well known.

However, the roof carrier that is attached to the rain gutter is not only difficult to install and remove, but also damages the rain gutter itself when heavy loads are repeatedly placed on it. Often causes damage. Moreover, since it is a fairly expensive product, it is often stolen. Furthermore, since the installation is performed using a plurality of fastening bolts, it is not only time-consuming as described above but also mechanically complicated.

Therefore, as a solution to this problem, it is preferable to install the vehicle without using a rain gutter and using an existing carrier frame fixed to the top surface of the roof if the vehicle has an existing carrier frame. However, this type of roof carrier does not exist, and there is also no one that takes theft into consideration.

SUMMARY OF THE INVENTION An object of the present invention is to provide a roof carrier for a vehicle that has a simplified fastening mechanism to facilitate assembly and disassembly operations, does not cause damage to the vehicle body, and is equipped with anti-theft means. .

The roof carrier for a vehicle of the present invention includes a carrier bar connected to a pair of left and right parallel carrier frames fixed to the roof of a vehicle with their ends crossing each other, and a carrier frame and a carrier bar. and a clamp connecting the intersections of the two.

The clamp has a main body that has a connecting hole through which the end of the carrier bar is inserted and a clamping part that abuts the carrier frame from one side, a tightening bolt that is inserted through the main body, and a clamp that is screwed onto the tightening bolt and attaches to the carrier frame. a wedge member having an inclined surface that contacts and presses from the other side and a suppressing surface that presses the end of the carrier bar; a locking device attached to the main body; and a wedge member coupled to the key cylinder of the locking device and the main body. When the tightening bolt is tightened, the carrier frame is held between the holding part on the main body side and the inclined surface on the wedge member side, and the end of the carrier bar is held in the connecting hole. It is pressed and fixed by the suppressing surface of the wedge member, and when the locking device is operated to the locked position, the lever rotates to close the tightening bolt so that it cannot be operated, and when the locking device is in the unlocked position, the tightening bolt can be operated. The lever is configured to rotate to the desired position.

A pair of left and right carrier frames fixed to the side of the vehicle,
The carrier bar is bridged so that both ends thereof intersect, and this intersecting part is removably connected with a clamp.

That is, the end of the carrier bar is inserted into the connecting hole of the clamp and positioned at a desired position. At this time, the fixed clamping portion of the main body is brought into contact with the carrier frame from one side. Next, tighten the tightening bolt from the outside of the main body.
The wedge member is drawn toward the main body, and this tightening action presses the carrier frame from the other side, and holds the carrier frame under pressure together with the fixed clamping member on the main body side. At the same time, as the wedge member is tightened and moved, the end of the carrier bar positioned within the connecting hole of the main body is pressed by the wedge member, and the end of the carrier bar is fixedly held in the connecting hole.

That is, by tightening the tightening bolt, the wedge member acts as a wedge, and the entire clamp is fixed to the carrier frame, and at the same time, the end of the carrier bar is fixedly held and connected to the fixed clamp.

As a result, when the locking device is operated to lock, the lever covers the head of the tightening bolt and rotates in a direction that makes it impossible to operate. That is, manipulation of the tightening bolt by a third party is prevented and removal of the clamp from the carrier frame is prohibited.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the vehicle roof carrier according to the present invention will be described below with reference to FIGS. 1 to 3. Note that this embodiment shows an embodiment in which an existing carrier frame is used on the roof of an automobile. A vehicle equipped with this type of carrier frame is not limited to application to automobiles, and the installation location is not limited to the roof.

As shown in FIG. 1, a pair of left and right carrier frames 2.2 are installed on the roof 1 with substantially the full length in the longitudinal direction of the roof. The figure shows the right side when facing the front of the vehicle. The height of the carrier frame 2 is from the top of the roof 1 ■
A carrier par 3 is connected to the left and right carrier frames 2.2, which extends in the vehicle width direction perpendicular to the vehicle width direction and directly supports cargo. At least two are provided in the front-rear direction.Both ends of the carrier par 3 are connected to the left and right carrier frames 2.2 via clamps C.

In detail, the structure of the clamp C is such that the main body 10 is a plastic molded product or a die-cast product made of a light alloy. A rectangular connecting hole 12 corresponding to the cross-sectional shape of the carrier par 3 is provided in the upper part of the main body 10, and the connecting hole 12 has a diameter large enough for the carrier par 3 to be inserted therethrough. The front of the main body 10 is on the right side in the drawing when the vehicle is viewed from the side, and a fixed clamp piece (fixed holding part) 17 is fitted and fixed on the back side of the standing wall 13 at the front of the front.

The fixed clamp piece 17 is a relatively hard rubber molded product,
It is fastened to the standing wall 13 of the main body 1o with a stopper 18. Further, the standing wall 13 is provided with a bolt installation hole 15 that penetrates to the front surface, and the tightening bolt 3o is inserted through the bolt installation hole 15 into a tapered hole 16 having a diameter of 1° in the main body.

The head 31 of the tightening bolt 30 after insertion is visible from the front side.

The tapered hole 16 of the main body 10 has a truncated conical shape that expands rearward. Further, a locking device 4o, which will be described later, is installed in the main body 10 at a lower position of the bolt installation hole 15.

The wedge member 2o is screwed into the threaded portion 32 of the tightening bolt 30 and tightened together. This wedge member 20 is the main body 10
A tapered hole 22 is provided at the center of the casing-shaped base 21 to form a pair with the tapered hole 16 on the main body 10 side and form a pair with the tapered hole 16 on the main body 10 side. The tightening bolt 30 has a sufficient length so that the threaded portion 32 can be inserted into the tapered hole 22 and penetrated to the back side of the base 21. The threaded portion 32 of the tightening bolt 30 is screwed into a nut 33 that is attached to the back surface of the base 21 around the tapered hole 22 so as not to rotate together. Therefore, tighten the bolt 30 from the front side of the main body 10.
By screwing in the wedge member 20, the entire wedge member 20 is pulled toward the right side in the figure with respect to the main body standing wall 13 on the fixed side. Further, on the front side of the wedge member 20, a movable clamp piece 24, which is of the same quality as the fixed clamp piece 17 on the main body 10 side, is fastened by a stopper 25, forming a pair opposite to the fixed clamp piece 17. That is, by pulling the wedge member 20 by screwing in the tightening bolt 30, the movable clamp piece 24 works together with the fixed clamp piece 1.7 to clamp and hold the carrier frame 2 on the roof 1 from this diagonal direction. . The surface shape of the movable clamp piece 24 is formed as a curved portion 24 a with a concave inclined surface, and this curved portion 24 a contacts the surface of the carrier frame 2 . Therefore.

As the entire wedge member 20 moves as the tightening bolt 30 is tightened, the movable clamp piece 24 acts as a wedge and abuts against and presses the carrier frame 2 from one side.
The inclined force of the curved portion 24a acts on the wedge member 20, so that the wedge member 2o can move not only in the horizontal direction but also upward in the vertical direction in the figure. In order to smooth this horizontal vertical movement, a tapered hole 16 and a wedge member 2 on the main body 10 side that absorb the movement of the tightening bolt 30 are provided.
A tapered hole 22 on the o side is formed. Furthermore, the upper surface of the wedge member 20 is formed flat as a pressing part 26, and this pressing part 26 pushes up the end of the carrier par 3 from below and presses it against the upper surface of the connecting hole 12 of the main body 1o to fix and hold it. It looks like this.

On the other hand, the locking device 40 that is fitted and fixed to the main body 10 through the key cylinder 41 has a long plate-shaped lever 42 on the central axis at the front end of the key cylinder 41, which stops one end of the locking device 40.
are connected with. This lever 42 is inserted into a rotation slit 19 provided in the main body 1o, and is rotatable within this slit 19. That is, when the lever 42 is rotated in a predetermined direction by locking/unlocking with a key (not shown), the lever 4
The other end of 2 enters the upper bolt assembly hole 15 and closes, and the tightening bolt 3 that was previously visible on the front side is closed.
o in the direction of covering the head 31 inoperably or releasing the head 31 so that the head 31 can be operated (see FIG. 3).

Next, the operation and usage mode of this embodiment is such that at least two carrier frames 3 are connected in the longitudinal direction of the vehicle so as to bridge a pair of left and right carrier frames 2.2 fixed to the vehicle side. . Left and right carrier frame 2.2
The ends of the carrier par 3 that intersect are connected by a clamp C.

First, the end of the carrier par 3 is inserted into the connecting hole of the main body 10 of the clamp C, and positioned at a desired position. At this time, the fixed clamp piece 17 of the main body 10 is brought into contact with the carrier frame 2 so as to be held from one side. Then,
When the tightening bolt 3o is tightened from the outside of the main body 10, the wedge member 2o is drawn toward the main body 10, and this tightening operation presses the carrier frame 2 from the other side, and the carrier frame 2 is tightened together with the fixed clamp piece 17 on the main body 10 side. The frame 2 is held under pressure. At the same time, due to the movement of the wedge member 20 by tightening the tightening bolt 30, the end of the carrier par 3 positioned within the connecting hole 12 of the main body 10 is pushed from below by the flat suppressing part 26 of the wedge member 20. The end portion of the carrier par 3 is fixedly held in the connecting hole 12 by being pressed upward.

That is, by tightening the tightening bolt 3o, the wedge member 20
acts as a wedge, and the entire clamp C is fixed to the carrier frame 2, and at the same time, the end of the carrier par 3 is fixedly connected to the fixed clamp C.

From this, when a key is inserted into the key hole 41a of the locking device 50 to cover the head 31 of the tightening bolt 30 and the lock is operated, the lever 42 rotates in the direction of closing the bolt assembly hole 15 on the main body 10 side. However, the head 31 of the tightening bolt 3o is closed from the outside, and operation of the bolt by a third party is prohibited, making it impossible to remove the clamp C from the carrier frame 2, and theft of the roof carrier can be prevented.

As explained above, the vehicle roof carrier according to the present invention has a structure that is attached to a rain gutter around the roof, but unlike the conventional structure that is attached to a rain gutter around the roof, it is difficult to install and remove it, and it is difficult to carry heavy loads. The problem of damage to the rain gutter itself is resolved by installing the rain gutter. Moreover, since the clamp is simply tightened with a single tightening bolt, the labor required for attaching and detaching as described above is simplified, and the mechanism is also simplified, which has the effect of reducing costs. be.

Furthermore, by providing a cover that closes the tightening bolt and a locking device that locks this cover to the clamp body, concerns about theft are also eliminated.

Furthermore, since the locking device is integrated into the clamp body, there is no need to separately prepare tools such as a chain and a lock key, which are conventionally seen as anti-theft measures.
