Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cargo loading device for the roof of an automobile.

Automobiles have trunks and other luggage storage spaces, but in order to transport items that cannot fit in the trunk, roof carriers (roof racks) are often installed as temporary cargo spaces these days. There are several types of roof carriers that can carry small luggage, ski equipment, surfboards, bicycles, etc. However, when it comes to larger cargo, such as boats (fishing boats, motorboats, etc.), there are almost no carriers that can load larger cargo onto the roof of a car, even if it falls within the limits of road traffic laws. Even if there is cargo, it is only possible to load it, and it is impossible for one person to load and unload the cargo, so it is usually loaded onto a separate trailer and towed by a car, but this does not require a large parking space. There are other issues, such as the need for a parking lot. Furthermore, even after being lowered from the carrier to the ground, if the cargo is large, it is often difficult for one person to move it to the desired location.

The present invention relates to a cargo loading device on the roof of an automobile, and is an object of the present invention to solve the problems of conventional devices. In other words, the objective is to not only be able to load large and long cargo such as boats, but also to be able to easily stack and unload cargo even by one person, and to be able to load and unload the cargo on either slopes or vertical surfaces. To provide a cargo loading device for the roof of an automobile that can be moved anywhere.

Next, the usage conditions and effects of the present invention will be explained with reference to the above embodiments.

First, when stacking the boat b on the cargo loading device on the car roof part a, turn each of the locking nuts 24 and 25 at the bottom of the truck 19 and remove the protruding part as shown in the right half of Fig. 3. The frame rod 5 and the inner frame rod 10 are pulled up from the locking round holes 28 and 29, and the inner frame rod 10 and the truck 19 are set free with respect to the outer frame rod 5 and pulled down from behind. The approximate center of the boat b is placed on the boat support plate 30 of the trolley 19, and the front and rear parts are tightened and fixed with belts 35, and the inner frame rod 10
Turn it upside down so that the leg rod 14 is at the bottom. Then, the inner rollers 22 on both sides of the truck 19 are engaged and rolled within the inner frame rod 10, and the truck 19 is mounted and fixed near the rear of the inner frame rod 10. In this state, the wire 34 of the inner frame side winch 13 is hooked onto the wire 38 from the horizontal bar 15 of the leg rod 14 and wound up, and the wire 39 between the leg lever 14 and the horizontal bar 12 at the rear end of the inner frame lever 10 is wound up.
Stand on your feet until you feel tension.

Next, as shown in FIGS. 4 and 5, the inner frame rod 10
The front part of the frame lever 10 is lifted up and the hook 18 at the front end thereof is hooked on the horizontal bar 7 at the rear end of the outer frame lever 5, so that the front end of the inner frame lever 10 is brought close to the rear end of the outer frame lever 5. In this case, trolley 19
Since the rear inner roller 22 is locked by the stopper at the rear end of the inner frame rod 10, it does not come off. Next, the wire 33 of the winch 9 on the outer frame side of the outer frame rod 5 is extended backward from the top via the front pulley 8, and the wire 33 of the winch 9 on the outer frame side of the outer frame rod 5 is
0 is connected to the trolley 19 on top.

When the winch 9 is wound up in this state, the inner roller 22 rolls within the inner frame rod 10 and is pulled up.
After passing the front end of the inner frame rod 10, the outer roller 21 engages within the outer frame rod 5 and rolls forward. Therefore, as shown in Fig. 1, the outer frame rod 5 is stopped at a predetermined position approximately in the center, and then the hook 18 of the inner frame rod 10 is removed, and the inner frame rod 10 is turned upside down and folded with the leg rod 14 at the top. , insert it between the outer frame rods 5 from its front end (see Figures 2 and 3). Next, turn the respective locking nuts 24 and 25 of the truck 19 to lower them, and as shown in the left half of FIG. 29 and lock it. Furthermore, the wire 33 of the outer frame side winch 9 is hooked to the wire 36 attached to the front part of the boat b, and the wire 34 of the inner frame side winch 13 is hooked to the wire 37 attached to the rear part of the boat b, and the wires are locked in a tensioned state. let Boat b is now securely loaded onto this device.

Next, in order to load and unload boat b from this device after transporting it to the target position, remove the wires 33, 34 of each of the winches 9, 13 from the wires 36, 37 on the boat side, and tighten the locking nuts 24, 25. Turn it to release the lower protrusions from the locking round holes 28, 29 of both frame rods 5, 10, as shown in the right half of FIG. Next, pull out the inner frame rod 10 rearward, turn it upside down, and attach the inner frame side winch 1 in the same way as when stacking.
3, the leg rod 14 is erected, the hook 18 at the front end is engaged with the horizontal crosspiece 7 at the rear end of the outer frame rod 5, and the leg rod 14 is placed diagonally (see FIG. 5). After that, the wire 33 of the winch 9 on the outer frame side
is hooked onto the trolley 19 via the pulley 8 at the front end, and while loosening the wire 33, the trolley 19 with the boat b is moved backward along the outer frame rod 5 with the outer rollers 21, and then the inner frame rod 10 is moved with the inner rollers 22. descend diagonally along the Then, the inner roller 22 at the rear of the truck 19 is stopped by a stopper at the rear of the inner frame rod 10, and the truck 19 is stopped by a stopper at the rear of the inner frame rod 10.
Remove the wire 33 of the winch 9 on the outer frame side, remove the hook 18 from the outer frame rod 5 side, and
Just set it to 0.

After that, if the place to float the boat b is on a slope, hold the front part of the inner frame rod 10 as shown in FIG. It is sufficient to fold the leg rods 14 at a position where the boat b floats on the water surface, remove the belt 35, and float the boat b. On the other hand, in the case of a quay without an inclined surface, as shown in FIG.
Remove 4. To the wire 39 at the rear end of the inner frame rod 10,
The wire 33 of the winch 9 on the outer frame side is hooked through the pulley 8 at the front end, and the hook 18 at the front end of the inner frame rod 10 is locked with the locking part 42 near the lower part of the column 31 on the rear bumper 32. Then, the wire 34 of the winch 13 on the inner frame side is lowered through a pulley at the rear, and is hung on the wire 40 that holds the boat b. At this time, the wire 3 of the winch 13
It is desirable that the number 4 be made into two pieces below the pulley to eliminate twisting and prevent the boat b from rotating. After that, the wire 33 of the winch 9 on the outer frame side
By loosening, the inner frame rod 10 uses the locking portion 42 of the support column 31 to which the hook 18 is locked as a fulcrum,
Boat b can be suspended from the quay like a crane and floated on the water surface. In the above case, the wheels 16 may be used as a pedestal for supporting the lower part of the bumper 32.

When pulling boat b onto land, in a place with a slope, the belt 35 of boat b is fastened to the trolley 19 on the inner frame rod 10 in the water, and the wheels 16
You can use it to pull it up. At this time, the end of the wire 34 of the inner frame side winch 13 may be hooked to a fixed object on land, and the inner frame rod 10 may be pulled up along the slope by winding up the winch 13. Also, when pulling up boat b on the quay, contrary to when lowering it, you can pull boat b up in the water using the wire 3 of the winch 13 on the inner frame side.
4, and by hoisting the outer frame side winch 9 to raise the inner frame rod 10 as a crane, the boat b can be pulled onto the quay.

To place the lifted boat b on this device,
Just do what I said at the beginning. In addition, the roof part a
When the boat b is not placed on the boat b, the entire device may be removed from the roof part a, but the outer frame rod 5 may be left and the inner frame rod and truck 19 are removed. In the above embodiment, a case has been described in which a boat is loaded as cargo b, but it goes without saying that other long and large cargo may be loaded by changing the shape of the boat support plate 30 of the truck 19.

As is clear from the above, the present invention has the following effects.

First, not only can long and large cargo such as boats be loaded, but one person can also load and unload cargo onto the roof. In other words, with conventional roof carriers (roof racks), it is possible to load small luggage, ski equipment, surfboards, bicycles, etc., but it may be impossible to load longer or larger cargo than that, or it may be necessary to simply load the cargo. 2 for stacking and unloading things there.
It required more manpower. Therefore, the vehicle is often loaded onto a separate trailer and towed, but this poses other problems such as the need for a large parking area. However, the present invention has an outer frame rod fixed to the roof portion as described above, an inner frame rod housed inside the outer frame rod, a truck, and two winches. Therefore, when stacking cargo, the inner frame rod is lowered to the ground, the cargo is placed on the truck, and then the truck is pulled up with a winch along the inner frame rod, which is connected to the outer frame rod diagonally, and the outer frame rod is loaded onto the truck. All you have to do is pull it to a predetermined position on the rod and fix it, and unlike the past, this work can be easily done by one person. Also, when unloading, pull out the inner frame rod, connect it to the drawer outer frame rod, place it diagonally on the ground, and use the outer frame rod and inner frame rod as rails to lower the trolley on which the boat is placed by gradually loosening the winch. Just go. Therefore, loading and unloading from the roof to the ground can be easily carried out by one person.

Second, one person can easily move the cargo unloaded from the roof to the desired location, even if there is a slope or step. That is, conventional roof racks are only capable of loading cargo, and after being lowered to the ground, some other transport means must be used to move the cargo. Furthermore, in places where there is no other means of transportation, manual labor is required, and large and long cargo cannot be moved to the desired location by one person. However, in the present invention, as described above,
The removable inner frame rod has legs with wheels that allow it to stand on, so the inner frame rod on which a cargo-carrying cart is placed can be used as a two-wheeled handcart or handcart to move across a flat or sloped surface to a desired position. It can be moved by people. In addition, when pulling up the inner frame rod from an inclined surface, if the end of the wire is hooked to a fixed object, one person can wind the winch and pull it up. Furthermore, the inner frame rod can be used as a crane jib.
The cargo is suspended by the wire of the winch on the inner frame side, and lifted and lowered by the winch on the outer frame side. Therefore, unlike the conventional system, it has useful effects such as being able to lower the boat from the quay to the water surface or lift it from the water surface to the quay surface by one person, as in the above-mentioned embodiment.
