DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel ratchet buckle and a lashing belt system using the same.

[0002]

2. Description of the Related Art In recent years, with the expansion of distribution mechanisms and the development of transportation technology, the amount of cargo transported has also increased dramatically, and the means of transportation have been advanced and diversified. Along with this, means for safe and secure holding and fixing during transportation of merchandise cargo is required, and a lashing belt system has been widely used as the most advanced tool for that purpose. The lashing belt system is, for example, a belt system that fixes a cargo or the like using a hook attached to a tilt of a truck bed or a corresponding track rail attached to a route van.

The most standard type of the lashing belt system uses a ratchet buckle as shown in FIG. 1 and has a hooking means 2 such as a hook at one end (in FIG. 2, a sewn loop). Is fixedly attached to the ratchet buckle 1 and a belt 5 having a hooking means 4 such as a hook at one end.
Is inserted into the spreader bar of the ratchet buckle 1 and mounted to form a single belt as a whole.
This lashing belt system, as shown in FIG.
For example, the cargo loaded on the truck bed is so-called tightened so as not to collapse or move. First, the ratchet buckle is set in a free state, the belt 5 is pulled out, and a belt having a sufficient length is necessary. Take the slack and hook the hooks at both ends of the lashing belt system at predetermined positions (the hooks under the tilt of the truck bed in FIG. 2), and then rotate the ratchet with the handle 6 of the ratchet buckle to ratchet the belt 5 Take up the buckle to secure the load.

Although the lashing belt system using the ratchet buckle is much more convenient, efficient and effective than the case where the lashing belt is used for tightening only with ropes, it still has various disadvantages. The first disadvantage is that the position of the hook 2 from the ratchet buckle 1 is constant because the length of the belt 3 on the fixed side is constant. Since the size, shape, aspect, etc. of the cargo to be used are very various, the constant length of the fixed side belt 3 becomes the biggest bottleneck, and the lashing belt system can reduce the variety. It is not possible to cope properly, and not only is it difficult to carry out the packing work, but also the work is restricted.

[0005] Further, since the length of the fixed side belt 3 is not constant and variable, a load is always applied to the same portion of the fixed side belt, so that the belt is greatly worn and the durability is deteriorated. In addition, since the variable side belt also comes into contact with the ratchet buckle in a relatively short range, there is also a problem that, similarly to the fixed side belt, wear is severe and the durability of the belt is deteriorated.

Furthermore, in a conventional lashing belt system using a ratchet buckle, there are two belts, a fixed side and an adjustment side, and it is quite complicated and difficult to manufacture the lashing belt system by sewing them. It is necessary and does not increase the efficiency of production. The present invention solves the above-mentioned problems and provides a ratchet buckle that enables extremely high workability and a highly durable lashing belt system. The purpose is to provide itself.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a ratchet buckle having a ratchet buckle body and a fixed belt attached to a ratchet buckle body with an outer side (opposite to the ratchet buckle body) in a free movement direction. It consisted of an integrated cam buckle.

Further, using the above-mentioned ratchet buckle, the ratchet buckle is inserted through the cam buckle,
One piece attached to the ratchet buckle by letting the part protruding outward (moving direction side) from the cam buckle pass over the cam buckle into the belt insertion slit of the take-up bar of the ratchet buckle from the handle side (upper side). The lashing belt system was constituted by the above-mentioned belt and hooking means provided at both ends of the belt.

[0009]

According to the ratchet buckle of the present invention, the belt can be fixed and released at two places. In the lashing belt system of the present invention, there is no fixed belt, the lengths of the belts at both ends can be freely changed, and the position of the ratchet buckle can be adjusted to a position most convenient for the work during the packing operation. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings showing embodiments. Embodiment 1 FIG. 3 is a perspective view of one embodiment of a ratchet buckle according to the present invention, and FIG. 4 is a diagram schematically showing a central longitudinal section thereof. In the figure, 11 is a ratchet buckle main body, 12
Is a cam buckle. The configurations of the main body of the ratchet buckle and the cam buckle 12 itself are not different from conventional ones. The cam buckle is disposed so that the right direction in FIG.

Reference numeral 13 denotes a ratchet buckle handle. In this embodiment, when the pull bar is pulled in the direction of arrow A in the drawing, the winding bar 14 rotates in the same direction, and rotates so as to wind the belt. The direction of rotation of this winding can be reversed by changing the direction of the teeth of the ratchet 15 in the opposite direction. By changing the winding direction, it is possible to select whether the belt is wound up by pulling and tightening is performed, or the belt is wound up by pushing and tightening is performed. A gap 16 is provided between the ratchet buckle body 11 and the cam buckle 12 so that the belt can be pulled downward in FIG.

Embodiment 2 FIG. 5 is a diagram schematically showing a configuration of an embodiment of a lashing belt system using a ratchet buckle according to Embodiment 1. One belt 17 made of polyester fiber penetrates the belt insertion slit 18 of the take-up bar 14 of the ratchet buckle main body 11 from above to below in the figure. That is, the belt 17 has a loop formed on the upper side of the ratchet buckle, and one end is inserted from the upper side to the lower side through the belt insertion slit of the winding bar of the ratchet buckle, and the other end is inserted from the outer side to the inner side of the cam buckle 12. Is pulled out below.

Narrow hooks 19 are attached to both ends of the belt by forming loops. This latching means may simply form the end of the belt as a loop or a squeezing loop, and the hook may be a hook different from that of this embodiment, or a completely different hook means may be employed. Good. The length of the belt is not particularly limited, and may be an appropriate length according to the application.However, the belt is fastened with the belts at both ends from the bite between the take-up bar and the cam buckle. However, since the middle loop portion is a play portion, if there is a large amount of the loop portion, it is sufficient to take care of proper bundling or the like, so that a long belt does not cause any trouble.

Referring to FIG. 5, a description will be given of a loading operation method of the lashing belt system according to this embodiment. Prior to the loading operation, the ratchet 15 is released and the length of the belt 20 on the tip side from the take-up bar 14 and the length of the belt 21 on the tip side of the cam buckle 12 are operated by operating the lever of the cam buckle 12, respectively. Adjust according to the situation such as the luggage to be tightened and the loading or loading place of the luggage. In this lashing belt system, the belt at either end of the lashing belt system can be a fixed-side fixed belt. Which side is the fixed side can be determined based on whether it is easier to pull or push the handle of the ratchet buckle to wind up the belt.

After the hooks at both ends are respectively hooked at predetermined hooking points, the handle 13 of the ratchet buckle is
Is operated to wind up the belt 20, shorten the length of the belt 20, and tighten the packing. This packing operation is basically the same as the conventional lashing belt system using a ratchet buckle. When unloading the load, the belt may be loosened by pulling the release lever of the ratchet buckle body to open the ratchet buckle, or the cam buckle may be released to loosen the belt.

[0016]

According to the ratchet buckle of the present invention, unlike the conventional ratchet buckle, the belt can be fixed and released at two places, and a more suitable lashing belt system can be constructed. In the lashing belt system using the ratchet buckle of the present invention, in the lashing belt system using the conventional ratchet buckle, the belt on one side is a so-called fixed belt whose length is constant and does not change. In the lashing belt system, there is no fixed belt, and the length of the belt on both sides can be changed freely, so the position of the ratchet buckle during packing work can be set to the most convenient position for work, and belt damage is reduced As a result, the durability is increased, and the workability of packing is also extremely improved. By freely changing the length of the belts on both sides, it is possible to select whether the handle of the ratchet buckle should be tightened by pulling or pressing when tightening, which also improves the workability of packing. To contribute. Further, since only one belt is required, the number of necessary parts such as sewing is reduced, and the production efficiency is improved.
