Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a carrier, and particularly to a roof carrier for carrying cargo that is installed on the roof of a vehicle.

BACKGROUND ART For example, Japanese Patent Application Laid-Open No. 62-68154 discloses a vehicle loading platform device, and Japanese Patent Application Laid-Open No. 58-185342 discloses a vehicle luggage carrier. This vehicle luggage carrier is fixed to a gutter provided at the edge of the roof of the vehicle.

Problems that the invention aims to solve However, with conventional roof carriers that are attached to the gutter, it is difficult to install and remove them, and if heavy cargo is repeatedly loaded, the gutter itself can be damaged. There are many. Additionally, conventional roof carriers have complex configurations, are relatively ineffective, and are often subject to theft.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and provide a roof carrier for a vehicle with a locking device that does not damage the top surface of the roof and has a small number of parts.

Means for Solving the Problems The vehicle roof carrier of the present invention includes a clamp body provided with a connecting hole and a through hole for receiving the carrier bar together with the upper wall, and a main body disposed within the recess of the clamp body and abutting against the carrier frame. A side pad, a wedge member that is provided with a pressing part that presses the carrier bar and an insertion hole, a wedge side pad that is fixed to the wedge member and forms an inclined surface that comes into contact with the carrier frame, and one of the wedge member or the clamp body. The nuts arranged adjacent to each other are inserted into the through holes of the clamp body and the insertion holes of the wedge member, and the wedge members are tightened together with the nuts against the clamp body, so that the body side pad of the clamp body and the wedge side pad of the wedge member are tightened together with the nut. a bolt that clamps the carrier frame between the bolts and presses the carrier bar against the upper wall of the clamp body by a pressing portion of the wedge member;
and a locking device having a cap that is removably attached to the bolt or nut and is rotatable relative to the bolt or nut in the attached state.

Operation Place the clamp body and the wedge member in opposition to the carrier frame with the carrier frame in between, and lightly temporarily tighten the bolts and nuts. Next, the carrier bar is inserted into the connection hole of the clamp body and positioned. After that, when the bolt and nut are fully tightened, the wedge member and the clamp body are drawn toward each other, and the clamp body and the wedge member clamp the carrier frame, and the wedge member allows the carrier bar to move against the upper wall of the clamp body within the connecting hole. It is firmly fixed. In this case, the wedge member acts as a wedge when tightening the bolts and nuts, and both the carrier frame and the carrier bar can be firmly fixed at the same time by the clamp body and the wedge member.

Thereafter, the locking device is mounted on the bolt or nut such that the cap of the locking device can be rotated relative to the bolt or nut. If the cap is removed illegally, the cap will spin, making the bolt or nut inoperable and preventing the roof carrier from being removed.

Embodiment Hereinafter, embodiments of the vehicle roof carrier according to the present invention will be described with reference to FIGS. 1 to 15.

1 to 3 show a first embodiment of a vehicle roof carrier according to the present invention. The carrier frame 2 is fixed on the roof 1 at a height H from the top surface of the roof 1. Actually, a pair of carrier frames 2 are provided on the left and right sides of the roof 1 of the vehicle, and a carrier bar 3 that is substantially orthogonal to the carrier frames 2 and extends in the vehicle width direction is connected to the carrier frames 2 via clamps C. Actually, at least two carrier bars 3 are provided in the longitudinal direction of the roof 1.

A rectangular connecting hole 12 provided in the upper part of the clamp body 10 corresponding to the cross-sectional shape has an inner diameter through which the carrier bar 3 is inserted with a margin. A body-side pad 17 formed of a relatively hard rubber molded product is fixed to the lower recess 13a of the vertical wall 13 of the clamp body 10 with screws 18. The carrier frame 2 is brought into contact with the inner surface 17a of the body side pad 17. Further, the clamp body 10 is formed with an upper wall 14 against which the carrier bar 3 is pressed, and a tapered through hole 16 whose diameter gradually increases and is connected to the vertical wall 13, and is connected to the through hole 16 on the clamp body. An operation hole 15 is provided. Hexagonal head 31 of bolt 30 inserted into operation hole 15 and through hole 16
is arranged in the operation hole 15.

Also, the bolt 30 inserted into the clamp body 10
is further inserted into a tapered insertion hole 22 formed in the main body 21 of the wedge member 20. A nut 33 is disposed in a hexagonal hole 22a formed in the wedge member 20 so as to communicate with the insertion hole 22 so that it cannot rotate with respect to the member body 21. Screw the nut 33 onto the threaded portion 32 of the bolt 30 to remove the clamp body 1.

When using the vehicle roof carrier of the present invention, two carrier bars 3 are connected at right angles to a pair of left and right carrier frames 2 fixed to the roof 1 of the vehicle as described below.

Clamp body 10 across carrier frame 2
The inner surface 17a of the body side pad 17 and the pad 24 of the wedge member 20 are brought into contact with the carrier frame 2 so as to face each other, and the bolt 30 and nut 33 are lightly temporarily tightened. Next, the connecting hole 12 of the clamp body 10
Insert the carrier bar 3 into and position it. After that, when the bolt 30 and nut 33 are fully tightened, the wedge member 20 and the clamp body 10 are drawn together, and the clamp body 10 and the wedge member 2
0 holds the carrier frame 2, and the carrier bar 3 is connected to the connecting hole 12 by the wedge member 20.
It is firmly fixed to the upper wall 14 of the clamp body 10 inside. In this case, bolt 30 and nut 3
3, the wedge member 20 acts as a wedge, and both the carrier frame 2 and the carrier bar 3 can be firmly fixed at the same time by the clamp body 10 and the wedge member 20.

Thereafter, the locking device 40 is attached to the bolt 30 so that the cap 41 of the locking device 40 can rotate with respect to the bolt 30. That is, the key 42 is pressed into the cap 41.
When the cap 41 is pressed against the bolt 30, the slider 109 moves inside the cap 41 along the groove 103e against the elasticity of the spring 110. Therefore, the protrusion 109a of the slider 109 moves along the cam groove 105, and the rotator 104 is rotated relatively. This causes the latch 112 to retract into the rotator 104.
As shown in FIG. 1, the flat plate portion 103g of the shaft portion 103c rotates, and the latch 112 protrudes and engages with the annular projection 101b as shown in FIG. In this state, magnet 1
08 engages with the recess 114 of the cap 41, the rotator 104 does not rotate even if the cap 41 is pressed against the bolt 30, so the spring 110
Since the slider 109 cannot be moved inward against this, the cap 41 cannot be removed from the bolt 30 and the bolt 30 cannot be rotated. Since the entire surface of the cap 41 is formed with a smooth surface so that it cannot be manipulated by a tool, the locking device 4
0, if the cap 41 is removed illegally, the cap 41 will spin idly, making it impossible to operate the bolt 30 or nut 33, thereby preventing the roof carrier from being removed.

On the other hand, when removing the vehicle roof carrier from the carrier frame 2, the magnet 114 of the key 42
The magnet 108 is pushed into the recess 103d by the repulsive action of
By moving the cap 41 in the direction of separation from the rotator 104, the engagement between the cap 41 and the rotator 104 is released, and the rotator 104 becomes rotatable. When the cap 41 is pulled out from the bolt 30 in this state, the slider 109 moves inward and the rotator 104 is rotated, so that the latch 112 moves from the extended state shown in FIG. 9 to the retracted state shown in FIG. 11. Therefore, as the slider 109 moves outward, the 10th
Cap 41 can be removed from bolt 30 as shown. When the cap 41 is removed from the head 31, the bolt 30 can be rotated in the removal direction via the head 31.

The above-described embodiments of the invention may be modified. For example, in the embodiment of FIGS. 1-3, the bolt 30
Although an example is shown in which the locking device 40 is attached to the head 31 of the head 31, it is also possible to attach the locking device 40 to a nut instead of the bolt 30. As a second embodiment of the present invention, an example in which a locking device 40 is mounted on a nut 43 will be described with reference to FIGS. 4 and 5.
In these drawings, the same parts as those shown in FIGS. 1 to 3, FIGS. 6 and 15 are designated by the same reference numerals, and explanations thereof will be omitted.

As is clear from FIGS. 4 and 5, in the second embodiment, the bolt 30 is arranged in the opposite direction, the head 31 is fixed to the wedge member 20 side, and the threaded part 3
The locking device 40 is attached to and detached from the nut 43 connected to the nut 2. It will be obvious to those skilled in the art from the disclosure of this specification that the nut 43 can be formed to have the same shape as the head 31 of the bolt 30 shown in FIGS. 8 and 10.

Further modifications of the above-described embodiments of the invention are possible. For example, in the above embodiment, an example was shown in which an existing carrier frame was used on the roof of an automobile, but the present invention is not limited to application to passenger cars as long as the vehicle is equipped with this type of carrier frame. It is also clear that the locking device 40 is not limited to the type and construction described above, but that bolting or nut locking devices of various constructions can be used. Further, the pad may be omitted and formed integrally with the clamp body or the wedge member.

Further, either the bolt 30 or the nut 33 may be insert molded into the wedge member 20, or may be integrally molded with the wedge member 20 from metal or resin.

Effects of the Invention The vehicle roof carrier according to the present invention can be constructed with a small number of parts without damaging the top surface of the roof, and can reliably prevent theft by providing a locking device.
