DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cargo carrying device mounted on a roof of an automobile for carrying cargo.

[0002]

2. Description of the Related Art Conventionally, when long ladders and pipes are loaded and transported on a roof of a working car, for example, the ladders and pipes are loaded and transported on a carrier mounted on the roof.

[0003]

When a long ladder or pipes are loaded and transported on a conventional roof-mounted carrier, those having long dimensions have a considerable weight, and the work vehicle carries a large amount of loads and people. As a necessity, wagon-shaped vehicles are often used, but as is well known, these vehicles have a high roof, and heavy ladders and pipes are loaded and unloaded with considerable heavy labor, resulting in severe fatigue and a high working position. If not lifted up, the work must be performed using a stepladder or the like, and there is a problem that there is a risk of falling and damaging the legs.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a long and heavy ladder, pipes and the like that can be loaded and unloaded at a high position on a roof. The loading and unloading work can be done at a comfortable position that can be reached by reaching in a normal posture while standing without using a stepladder. It is an object of the present invention to provide a cargo transport device for a roof of an automobile which is lost.

[0005]

In order to achieve the above object, a cargo transport apparatus for a roof of a vehicle according to the present invention is provided with two base frames parallel to the width direction of the roof of the car. Is provided with a drive shaft that is inserted in a right angle direction and that is rotated by a motor in a direction parallel to the base frame. A tiltable loading frame is provided on the base frame in which a tilt guide wheel attached to an upper end of a swing shaft having a lower end pivotally attached to the base frame is loosely fitted and the tip end side tilts obliquely downward in a direction parallel to the base frame. At the rear end of the tilting cargo frame, a base is fixed to the drive shaft, and the tip end is pivotally connected to the rear end of the tilting loading frame to lift the rear end of the tilting loading frame and tilt the tip end. A mounting rod is pivotally mounted, and a mounting device to be mounted on the roof is attached to the lower surface of the base frame.

[0006]

[Function] When the switch is turned on, the tip of the lifting rod is lifted by the rotation of the motor, and the inside of the tilting cargo frame is lifted,
Since the tip side is pushed down diagonally downward from the roof, the tilting loading frame descends diagonally downward from the roof to the outside of the vehicle, so ladders and pipes are loaded into the tilting loading frame at a low position while standing normally on the road. can do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments will be described with reference to the drawings.
In FIGS. 1 to 4, the base frames 1 and 1 are formed by using, for example, a trapezoidal angle steel having substantially the same length as the width of the roof R of the vehicle body and forming a bottom surface 2 with one surface bent in an L shape. The bottom 2
The carriers 3, 3,..., Each having a structure to be attached to the roof of the vehicle body, are attached to the lower side of both ends of the vehicle with screws 4, 4,. The tilting loading frames 5, 5 are formed of a substantially square hollow column made of iron material, and are formed by notching grooves 6 in a straight line on one side of an outer side surface to form opposed sliding bottom surfaces 7, 7 and tilt. A sliding groove 8 having a curved sliding bottom surface 7 is formed in the loading frame 5 and is provided in parallel above the base frame 1.

The inclined guide wheels 9, 9 are loosely fitted in the sliding bottom surface 7 on the outer tip side (left side in FIG. 1) of each inclined loading frame 5, and the rotating shaft 10 of the inclined guide wheels 9 A lower end of the base frame 1 is pivotally supported by a swing shaft 11 pivotally attached to the lower side of the base frame 1 from below. More specifically, the swing shaft 11 is a swing support shaft 13 mounted in a horizontal direction at right angles to the vertical surface 12 of the base frame 1.
The lower end is pivotally connected to the upper end, and the upper end is inserted into the notch groove 6 of the tilting loading frame 5 provided in the upper direction of the base frame 1 in a parallel direction, and the upper end is rolled in the sliding bottom surface 7. Guide wheels 9, 9
And the tiltable loading frame 5 is slid in parallel with the base frame 1 so as to be tiltable.

The lifting rods 14, 14 are pivotally connected to a lifting shaft 15, which is inserted in the width direction into the inner end of the tilting cargo frame 5 (the end opposite to the position where the inclined guide wheels 9 are provided). The base portion is fixed to a lifting shaft 16 inserted in the base frames 1 and 1 at right angles. The tilt drive motor 17 is mounted on a motor support 18 mounted outside the vertical surface 1 of the base frame 1, and is connected to the lifting rotary shaft 16. It is preferable to use, for example, a gear torque motor (with a brake) as the tilt drive motor 17. The forward / reverse switch 19 is connected to the tilt drive motor 17. The loading frame mounting screws 20, 20,... Are mounting screws mounted on the upper surfaces of the tilting loading frames 5, 5 for mounting the loading frame described later.

In the embodiment shown in FIG. 5, a substantially rectangular slider 21 is slidably and loosely fitted into the sliding groove 8 of the tilting loading frame 5 in place of the tilting guide wheel 9 so as to slide freely. It may be attached to.

Further, an auxiliary frame 22 shown in FIG.
Shows one embodiment of frames of various shapes which can be mounted and replaced on the upper side of the tilting loading frame 5 by loading.
For example, when the auxiliary frame having such a configuration is inserted and attached to the screw 20 for mounting the tilting loading frame 5, it is more convenient to load a ladder or piping equipment having a longer dimension than directly loading the tilting loading frame 5. Become.

[0012]

As described above, according to the present invention, it is possible to lower the load outward and diagonally downward from the roof at a high position of the vehicle body. Even if long and heavy loads are handled, the work is easier and less dangerous, and the work efficiency is significantly improved.
