Abstract

PROBLEM TO BE SOLVED: To easily and completely tighten loads by simply and easily fitting a hook device for hooking a rope on a load space frame in tightening the loads with the rope to a load carrying vehicle. SOLUTION: This hook device is constituted of a box body 2 with its upper part opened, a round bar 3 with ends fixed to both side surfaces 2a, 2b of the outer and inner sides of the box body 2, and a ring 1 supported by the round bar 3 with a play provided in the box body 2. By fitting the box body 2, for example, to the inside of the side part frame of a load space, the ring 1 is kept in a storage position where it is stored in the box body 2 with its dead weight when the hook device is not used. At a using position where the ring 1 is pulled upward and the lower end part of the ring 1 is engaged with the round bar 3, the ring 1 can be rotated around the round bar 3 in the longitudinal direction and width direction of a vehicle body, and the rope can be hooked in such a condition as the ring 1 is inclined in the longitudinal direction and axial direction of the vehicle body.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hook device for securing a load of a load carrying vehicle.

[0002]

2. Description of the Related Art When a luggage loaded on a luggage carrier of a luggage carrier such as a trailer or a truck is fastened by a rope, a hook device for hooking the rope is attached to a peripheral member of the luggage carrier.

Conventionally, as a hook device, as shown in FIG. 3, for example, a clamp b is fixedly welded onto a mounting member c made of a flat plate, and a ring a is rotatably fitted to the clamp b. An assembly of a hook device, in which the mounting member c is fixedly attached to a required position on a carrier, is generally used.

As shown in FIG. 4, for example, a mounting plate (flat plate) e is fixed in a housing d, and a ring a 'is attached to the mounting plate e.
And a ring a 'is slidably fitted in the holes f, f to form an assembly of a hook device. When not in use, the ring a 'slides downward by its own weight and is stored in the housing d, and when in use, the ring a' is lifted up to the use position where the stopper plate g contacts the mounting plate e. A retractable hook device, which is used to pull out a rope and hook it, has also been used.

[0005]

In the conventional rotary hook device as shown in FIG. 3, a notch is provided at a required position on a floor plate forming the upper surface of a loading platform, and the hook device is embedded and mounted in the notch. Therefore, there is a problem that notch processing of the floorboard is required, which is troublesome and disadvantageous in cost.

In the conventional retractable hook device as shown in FIG. 4, the ring a 'slides only in the vertical direction and cannot rotate the ring a'. Very inconvenient when binding
There is a problem that it does not meet the needs of the user.

An object of the present invention is to solve the above-mentioned conventional problems.

[0008]

SUMMARY OF THE INVENTION The present invention provides a housing having an open top, a round bar fixed between the left and right sides of the housing inside the housing, By forming a hook device from the ring loosely supported by the round bar and mounting the housing, for example, inside the side frame of the carrier,
No special cumbersome processing is required for mounting the hook device, and the cost can be minimized.

Further, in the hook device, in a natural state, the ring is in a storage position where it is stored in the housing by its own weight.
In the use position where the ring is pulled out upward and the lower end of the ring is engaged with the round bar, the ring can rotate almost freely around the round bar in the longitudinal direction of the vehicle body, and also has a certain range in the vehicle width direction. Because it can rotate inside, it is possible to hook the rope with the ring tilted in the front and rear direction of the car body and the center of the car body, which is very convenient for luggage securing work and easy to secure accurate luggage Can be.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows a specific example of a hook device according to the present invention.
A round bar (shaft) 3 having both ends fixed to the outer side surface 2a and the inner side surface 2b of the housing 2, and a ring 1 which is loosely supported by the round bar 3 in the housing 2. Is done.

In a natural state, the ring 1 is in a state of falling downward due to its own weight.
Is located in a storage position almost housed in the housing 2, and when the upper end of the ring 1 is pulled upward, the ring 1 is pulled out to a use position in which the lower end is engaged with the round bar 3. I have.

As shown in FIG. 2, the hook device is mounted, for example, inside the required position of the side beam 4 of the bed frame of the trailer by tightening a mounting bolt 5 and a nut 6. In the case of a truck, it is attached to the inside of the side frame or the like of the carrier in the same manner as described above.

In the mounted state, the upper edge of the housing 2 fits into the opening 4a provided on the upper surface of the side beam 4, and the ring 1 is almost housed inside the side beam 4 when the hook device is not used. Held in state. In the use position where the ring 1 is pulled out upward and the lower end is engaged with the round bar 3, the ring 1 is
In addition to being able to rotate almost freely in the front-rear direction of the vehicle body around the center, the ring 1 can also rotate to some extent in the vehicle width direction within a gap between the upper opening of the housing 2 and the ring 1 in the vehicle width direction. When securing the loaded luggage, it is possible to hang a rope with the ring 1 tilted in the front-rear direction of the vehicle body and the center direction of the vehicle body, which is very convenient when performing the securing operation.

In the illustrated embodiment, the case where the hook device according to the present invention is attached to the side beam 4 which is fixed to the outermost end in the vehicle width direction among the components of the carrier frame of the trailer is shown. It is possible to similarly attach to not only 4 but also other loading frame components of the trailer.
Further, the hook device of the present invention can be mounted not only on a trailer but also on a side frame, a front and rear frame, and the like of a carrier of any luggage carrier such as a truck.

[0016]

As described above, according to the present invention, in a hook device for securing a load of a luggage carrier vehicle, it is easy to mount the device on a carrier frame or the like, and the ring is stored in the carrier frame when not in use. When used, the ring is pulled out from the body frame and can be rotated in the vehicle front and rear direction and the vehicle width direction, and the rope can be hooked with the ring inclined in the vehicle front and rear direction and the vehicle center direction, and accurate luggage securing Can be easily performed, and in combination with the simple structure and the low cost, a great effect can be obtained in practical use.
