Description

TECHNICAL FIELD The present invention relates to a load fixing method for easily fastening a belt used for preventing the load from collapsing on a loading platform or a loading platform of a truck.

In recent years, with the expansion of the distribution system and the progress of transportation technology, the amount of transported cargo has increased dramatically, and the means of transportation have progressed and diversified. Along with this, there is a need for means for safely and reliably holding and fixing goods during transportation, etc., and a lashing belt system has been widely used as an advanced tool for this purpose. The lashing belt system provides a method of securing cargo by means of belts using hooks on truck bed tilts and corresponding track rails attached to the route van. Various devices are provided for tightening the belt.

For example, a load binding machine disclosed in Patent Document 1 is configured by combining a winding device for winding a belt and an end stop device for fixing the end of the belt. The take-up device has a ratchet function and the end stop device has a hold-down member which allows only movement of the belt in the direction of tension and is intended to lock the belt.

Japanese Utility Model Laid-Open No. 7-44107

However, the load tightening machine disclosed in Patent Document 1 requires a handle for driving the ratchet due to its structure, and there is a problem that the handle on top of the load interferes with transporting the load. In addition, there is a large practical problem in dealing with the excess length of the belt drawn out from the cargo binding machine.

Here, a cargo binding machine using a conventional lashing belt will be described. FIG. 10(A) shows an external view of the lashing belt. Usually, the lashing belt consists of an extension belt with sufficient length to fasten the load as shown on the left side of FIG. 10(A) and a belt on the right side of FIG. It consists of a belt drive as shown.

In order to fasten the cargo with the lashing belt, the hooks 93 and 94 are locked to the locking positions of the cargo bed, the extension belt is hung on the cargo, and the belt is held as indicated by the dotted lines in FIGS. Pass to section 92 . The problem here is that since the length of the belt fixed to the belt driving section is fixed, when the hook 94 is engaged with the locking position of the loading platform, the position of the belt driving section relative to the load is determined. There is no degree of freedom.

Then, if the gap between the rack of the loading platform and the load is narrow, the belt driving part will be placed between the load and the frame of the loading platform, making the work extremely difficult. In addition, since the extension belt is long in order to handle various loads, if the length is adjusted by passing it through the belt holding part 92, an extra length of the belt that is not used for fastening the load is generated, and it takes time and effort to dispose of it. Further, if the twist of the belt is noticed at the stage of adjusting the length by passing the belt through the belt holding portion, it is necessary to remove the belt and pass the belt through the belt holding portion again. The above work is difficult for beginners, and there has been a strong demand for more efficient work.
