Abstract

PROBLEM TO BE SOLVED: To extremely reduce the damage due to oscillatory friction, and to sufficiently perform the function like a pulley by forming an inward flange on which a belt is put on and side, in the belt penetrating holes, and by providing the outer circumferences of the connecting parts between the flanges and the one piece body with roundness. SOLUTION: A body 1 is provided with holes 3 for passing through a bolt, and each hole 3 is not simply punched, but is cut and bent; and a flange 4 on which the belt is put on and moved is formed at the cut and bent part. By adjusting the height of the hole 3 and the thickness of one-piece, the end of the cut and bent part is butted on the belt. The outside 5 of the bent part is formed into natural roundness of thickness due to bending working, and the sliding belt is smoothly slid in both the front and rear directions by the roundness. When the thickness is thin and the roundness is not sufficiently large, the bending angle is made to be an obtuse angle, or the roundness is made larger than that in the natural bending. Then, the sliding of the belt is smoothed, and the one-piece sufficiently perform the function like a pulley.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved one-piece terminal for a lashing belt system.

[0002] 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 transportation means have been advanced and become 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. In such a lashing belt system, the corresponding one-piece (a type of hook fitting) fixedly attached to the belt is hung in the square hole provided in the track rail attached to the inner wall of the route van etc. A lashing belt system of the type that fixes cargos by going is rapidly spreading as a tool excellent in simplicity and reliability of loading work. In this conventional lashing belt system, the one-piece is almost fixedly attached to the belt, and the belt does not slide over a long range through the insertion hole provided in the one-piece, and the one-piece is attached to the belt at the place where the belt is attached. It is about swinging the head. For this reason, the problem that the portion in contact with the belt insertion hole was damaged quickly by friction was recognized as a problem, but it was resolved to improve the insertion hole itself, such as solving it, as well as improving the one-piece structure There is no movement at all.

[0003] On the other hand, the present inventor has repeatedly conducted research focusing on the importance of the conventional one-piece lashing belt system and its problems, and as a result, has found a lashing belt system having a new configuration that functions more effectively. And invented the invention, December 10, 1997
Filed a Japanese patent application. In the new lashing belt system, it is an essential requirement that the belt slide freely and smoothly over the insertion hole of the locking means such as a one-piece, and the locking means such as the one-piece function as a kind of pulley.

However, in the conventional one-piece, since the insertion hole is formed by punching and pressing, even if deburring is performed, the corner portion has a shape close to the edge, so that the belt slides with a strong resistance. Not only does this require a very high force, but the belt is also quickly damaged by friction, making the belt extremely low in durability. The one-piece of the present invention does not have such a problem at all, and even when used in a conventional lashing belt system, damage due to friction due to swinging is extremely small, and it is possible to sufficiently exhibit a pulley function, An improved one-piece that is necessary and fully adaptable to new lashing belt systems.

SUMMARY OF THE INVENTION The present invention is directed to a one-piece dress having a U-shaped vertical section for a terminal of a lashing belt system, wherein an inwardly facing belt slides on two belt insertion holes. Each flange was formed, and a radius was attached to the outer periphery of the connecting portion between the two flanges and the one-piece body. The radius should be as large as possible within the dimensions of the entire dress. It is preferable that the front ends of the two flanges come into contact with no gap, but there may be some gap. The outer shape of the flange may be flat or mountain-shaped. In the case of a mountain shape, it is preferable that the tip of the flange abuts and there is no gap. It is preferable that the flange be provided over the entire width of the insertion hole as much as possible.

[0006]

The belt passing through the insertion hole rides on the round portion and the flange at the connecting point between the flange and the main body and slides on the flange smoothly with very little resistance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings showing embodiments. 1 and 2 show a one-piece 1 according to the present invention.
FIG. 2 is a perspective view, and FIG. 2 is a sectional view taken along line II-II in FIG. In this one-piece, a main body 2 is formed by U-bending an iron plate punched into a predetermined shape into a U-shape.

The main body 1 is provided with a hole 3 for inserting a belt. The hole 3 is not simply punched out but is cut and bent to form a flange on which the belt can be moved by being cut and bent. 4 is formed. The cutting and bending for forming the flange may be performed after punching if it is press working. In this example,
By adjusting the height of the hole 3 and the thickness of the dress, the tip of the cut and bent portion is brought into contact. However, the leading end of the cut and bent portion may not be brought into contact, and there may be a gap. Further, the flange is flat, but may be mountain-shaped.

FIGS. 3 and 4 show a state in which a belt is inserted through the one-piece of FIG. On the outer side 5 of the bent portion, a natural radius of a plate thickness is formed by bending, and the belt sliding on the radius is smoothly slid in both front and rear directions as indicated by arrows in the drawing. For this reason, the one-piece can perform a sufficient pulley function for the belt. When the plate thickness is small and the radius is not sufficiently large, the bending angle is made obtuse or the radius of the radius is larger than the natural bending.

[0010]

According to the loop fitting of the present invention, the sliding of the belt is extremely smooth due to the round portion and the flange provided in the through hole of the belt, and the one-piece can sufficiently fulfill the function of a kind of pulley, and the one-piece can be attached to the belt. Even when fixedly mounted, the friction applied to the belt is small, the durability of the belt is improved, and the workability in the lashing belt system using this one-piece is improved.
