Description

[Detailed description of the invention] (Field of industrial application) This invention has two through rings at the ring attachment part at the base end of the belt, and the belt tip is passed through these two through rings and fastened. Concerning improvements to belts.

(Prior art) A belt that has two through rings at the ring attachment part at the base end of the belt, and which is fastened by passing the tip of the belt through these two through rings, cannot be tightened firmly once. , often loosened due to the passage of time or movement of the fastened object. For this reason, as a conventional technique to prevent this loosening, measures such as carving a large number of fine irregularities on the through ring to prevent slipping have been taken. However, this loosening prevention method does not provide a complete solution as the belt, which has been tightened once, often loosens over time. It was inconvenient as it required force to loosen the belt. Moreover, if the belt is used for a long time, the unevenness may damage the belt, which is not desirable.

(Problem to be solved by the invention) This invention solves the problem of this type of belt, which often loosens over time. Our goal is to provide long-lasting and convenient belts.

(Means for solving the problem) In order to solve the above-mentioned problems, this invention solves the above-mentioned problems by fixing the belt to one of the two through-rings at the ring-engaging portion at the base end of the belt. A rotatable loosening prevention member having a protruding rotation preventing portion is provided on the opposite side from the portion.

That is, once the belt according to this invention is firmly fastened, the protruding rotation suppressing portion acts as a resistance to prevent rotation caused by the return of the belt, and the friction between the belt and the loosening prevention member causes I can't go back and I can't loosen up.

The structure of this belt will be explained below by taking a cargo collapse prevention belt as an example. In FIG. 1, 1 is an elongated belt. This belt 1 may be made of any flexible material such as woven fabric or synthetic leather. This belt 1
Two through rings 2a and 2b are attached to the base end of the belt 1 with a predetermined degree of freedom. The through rings 2a and 2b may be made of metal or synthetic resin as long as they are strong enough to withstand the tension of the belt, but their shape is shown in FIG. 1 for ease of use. Generally, rectangular or square shapes are preferred. Also, its cross section is preferably rectangular or square in order to improve the frictional effect of the belt. Of the through-rings 2a and 2b, in this example, the through-ring 2a has a protruding rotation prevention portion 3 formed of the cloth of the belt 1 on the side opposite to the belt engagement portion, which is on the inside with respect to the object A to be fastened. A loosening prevention member 4 is provided. This loosening prevention member 4 must have a degree of freedom so that it can rotate around the through ring 2a so that the loosening prevention member 4 will not be damaged during belt fastening. Further, the protruding rotation preventing member 3 may be made of a different material from the loosening preventing member 4 as long as it is firmly fixed to the loosening preventing member 4, but it is preferably strong. In this example, the sleeves of the belt 1 are sewn together so that they protrude.

FIG. 2 is a perspective view of the entire device in use.

As shown in the partial cross-sectional view (Fig. 3) showing the state of use, this cargo collapse prevention belt having such a structure prevents the movement of the belt 1 in the direction of the arrow P as it tries to return with the passage of time. Although the loosening prevention member 4 rotates in the direction of the arrow Q in conjunction with friction, if the belt 1 and the rotation prevention member 3 come into contact with each other due to the resistance of the rotation prevention member 3 having the protrusion,
The loosening prevention member 4 cannot rotate any more, and the belt 1
This is to stop the movement in the direction of the arrow P and prevent loosening.

When the loosening prevention member 4 with the protruding anti-rotation member 3 is attached to the fastening object A only to the outer ring 2a, the effect is the same as when it is attached to the inner ring 2a. However, if both the through rings 2a and 2b are engaged as shown in FIG. 4, further frictional action will be exerted and the belt 1 will be more effectively prevented from loosening.

Furthermore, in any case, as shown in FIG. 5, the protruding rotation inhibiting member 3 of the loosening prevention member 4 that is located inside of the fastening object A is made long enough to be grasped by hand, and is provided as a handle part 5. By pulling the handle portion 5 toward the through-rings 2a, 2b, the through-rings 2a, 2b of the belt 1, once tightly fastened, can be easily loosened and opened easily with a little force. (See FIGS. 6A and B) The reason for this is not clear, but by pulling the loosening prevention member 4 toward you with the handle 5 and rotating it in the opposite direction, the belt 1 and the loosening prevention member 4
It is thought that this reduces the contact area with the surface and reduces frictional resistance. Note that while the object is being fastened, the handle portion 5 functions as the protruding rotation suppressing member 4, so that the effect of preventing the belt 1 from loosening does not decrease. Further, FIG. 7 shows another example of a cargo collapse prevention belt in which the handle portion 5 is formed of a metal fitting.

(Function) In order to use the cargo collapse prevention belt according to this invention with such a configuration, the other end 7 of the belt 1 is passed through the inside of the through rings 2a, 2b, and the through rings 2a, 2b are set as fulcrums. After folding it back to the opposite side, the belt 1 is further passed between the inner threading rings 2a, 2b and the outer threading ring 2b to the object A to be fastened, and the other end 7 of the belt 1 is strongly pulled and fastened. .

Once the belt 1 has been fastened, it can be removed by passing the handle 5 of the loosening prevention member 4 and pulling it toward the rings 2a, 2b to loosen it, and passing the other end 7 of the belt 1 through the rings 2a, 2b.

When the handle part 5 is not provided on the loosening prevention member 4, pull up the outer threading ring 2b to loosen it, and similarly thread the other end 7 of the belt 1 through the rings 2a, 2b.
Just pass it back through. Furthermore, a plurality of belts 1 may be used for one fastening object A, if necessary.

(Effects of the invention) As explained in detail above, the belt according to this invention can be used for any object due to the frictional action with the loosening prevention member and the resistance action with the rotation prevention member once firmly fastened. It has the excellent effect of maintaining constant and permanent tension without loosening even with the passage of time, movement of the fastened object, etc.

In the experiment, the belt part 1 was formed of a car seat belt material with a length of about 5 m, and a rotation suppressing member 3 with a length of 2 cm including a protrusion of about 5 mm made of the same material, a rectangular metal through ring 2a, This belt made of 2b did not come loose even when four adults pulled it with all their might from both sides.

Further, the belt according to the present invention provided with the handle portion 5 shown in FIG. 5 has the above-mentioned effect of preventing loosening, and also has the excellent effect that once the belt is tightly tightened, it can be released with a small amount of force. I can do it.

Therefore, in this example, it is suitable for use as a belt to prevent collapse of cargo, but it can also be used in a wide range of other applications such as suitcase protection belts and fastening belts for athletic shoes.

Further, as additional effects, the loosening prevention member reduces the contact area between the belt and the threading ring, so there is less damage to the belt itself, and the simple structure makes it easy to operate.
