BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a side frame member of a truck carrier. More specifically, the present invention relates to a structure of a side frame member provided with a hook (hereinafter referred to as a lashing hook) engaging portion attached to a luggage tightening rope end of a truck. FIG. 3 shows a state in which the load b is placed on the truck carrier a and is tightened by the tightening rope c. Such a tightening rope c has been hooked from the side of the fan d on the rope hook e provided on the side frame member of the luggage carrier. As shown in FIG. 4 (a), the rope hook e had a key-shaped rope hook e fixed to the frame material f on the bed by welding or the like at appropriate intervals. Alternatively, as another example, as shown in FIG. 4 (b), there is also one in which a long U-shaped long mold material g is fixed to the luggage carrier side frame material f. All of these are dangerous because they exist as protrusions on the outside of the side frame member f, and their mounting is troublesome. In particular, in the one shown in FIG. 4 (b), since it is continuous in the front and back, the danger as a protrusion is eliminated as compared with the one in FIG. There is a problem in that the hook may be displaced in the front-rear direction of the loading platform, and this cannot be regulated.

SUMMARY OF THE INVENTION In view of the drawbacks of the prior art, the present invention integrally forms the locking portion of the lashing hook attached to the end of the rope when molding the side frame member, and, as in the conventional case, An object is to provide a side frame member having no protrusion.

[0003]

A T-shaped flange portion 2 is integrally formed above a main body portion of a side frame member 1, and is formed between one flange 2b of the T-shaped flange portion 2 and the main body portion. Groove
An edge portion of the bed floor is fitted in 2c, and holes 5 for locking lashing hooks are provided at appropriate intervals in the longitudinal direction of the other flange 2a. The side frame member 1 is a roll-molded product or an aluminum extrusion-molded product.

[0004]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1 and FIG. The side frame member of the present invention can be formed from a strip member by roll molding by a multi-stage roll as shown in FIG. 1, or can be an aluminum extrusion molded product as shown in FIG. Below in FIG.
The molded article will be described. In FIG. 1, the main body of the side frame member 1 has a U-shaped cross section, and a T-shaped flange portion 2 is integrally formed on the upper portion thereof. One of the flanges 2a of the T-shaped flange portion 2 is a hooking portion of the lashing hook 3, and the other is a groove portion 2c for receiving the edge portion of the floor plate 4. The T
The mold flange portion 2 is formed by multi-stage roll forming, and the flange portion has a thickness twice that of the strip material as shown in the drawing. The flange 2a for locking the lashing hook 3 is provided with a hole 5 in the longitudinal direction thereof. This hole 5 is a hole for locking the lashing hook 3, and by hooking this hole, lateral movement of the hook can be prevented.

FIG. 1 (b) shows a modification of the portion provided with the lashing hook locking hole. In this example, the flange 2a is inclined slightly downward to increase its strength. FIG. 2 shows the side frame member 1 molded from an aluminum extrusion mold material. In this case, the T-shaped flange portion is wide because it can be integrally formed from the beginning by extrusion molding.

[0006]

[Effect] The T-shaped flange portion is integrally formed on the upper portion of the side frame member 1. And the hole 5 was provided in this one side. By hanging the lashing hook on the hole 5 from the inside of the fan, an unreasonable force does not act on the fan unlike the conventional bag tightening, and the lashing hook 3 does not laterally shift. Further, since there is no member for locking the lashing hook as a protrusion on the side of the luggage carrier side frame member 1 or on the luggage carrier floor plate 4, it is preferable from the viewpoint of appearance.
