2. Description of the Related Art Japanese Patent Application No. 4-2 previously disclosed by the applicant
The technology of No. 6122 (see Japanese Utility Model Laid-Open No. 5-76978) (hereinafter referred to as a prior invention) is a fan structure for a freight vehicle that is configured by vertically stacking a plurality of fan members a made of a hollow extruded mold material. a is hollow and has a flat surface on the luggage compartment side, I-shaped holes b are formed at predetermined intervals in the longitudinal direction of the flat surface, and then the I-shaped holes b are opposed to each other. It has a tongue structure in which the tongue portion c for locking the load fastener is provided by bending the two sides inward (FIGS. 4 to 6). By the way, in the above-mentioned fan structure of the prior invention, since the locking hole b for locking the load fastener is integrally provided on the load chamber side of the fan member, it is necessary to provide a separate load lashing rail. Without, the weight reduction of the fan
Although it can contribute to a reduction in the number of assembling steps, when forming a locking hole in the fan body and processing it, bending two opposite sides of the locking hole inward to form the tongue portion c is a hollow extruded material. Was difficult and required many man-hours.

[Problems to be Solved by the Invention] It is easy to form a locking hole for a load fastener provided on the luggage compartment side of a fan member made of a hollow extruded type material, and the strength of a portion where an end fitting of the load fastener is engaged. The purpose is to provide a fuel for lorries that can be increased.

[0004]

Means for Solving the Problems In a fan for a freight vehicle, wherein a plurality of fan members 1 made of a hollow extruded mold material are vertically stacked, and a lock hole for a fastener is formed on the luggage compartment side, Both the upper and lower portions of the stop hole where the end fittings of the load clamp are locked are formed as the thick portion 4 continuously in the longitudinal direction.
A longitudinal groove 5 was provided in the groove 5, and a reinforcing member 6 made of a different material was fitted into the groove 5. Further, the groove 5 has a round cross-section. Further, the groove 5 has a trapezoidal cross section 5 '.

Embodiments will be described with reference to the drawings. FIG. 1 shows an uppermost stage fan member 1 of a fan structure constructed by stacking vertically. A description will be given below of the present invention applied to the uppermost stage fan member, but it can be provided in either the middle stage or the lower stage fan member. In FIG. 2, 2 is an I-shaped locking hole. The end fitting 3 (FIG. 1) of the load clamp is locked in this locking hole. As is clear from the cross-sectional view of FIG. 1, the upper and lower portions where the end fittings 3 of the load clamp are locked are thickened portions 4. A groove 5 is formed in the thick portion 4 during extrusion molding (FIG. 3). Then, a reinforcing member 6 made of a different kind of hard material that matches the shape of the groove 5 is fitted to reinforce the end fitting locking portion of the load clamp. The shape of the concave groove 5 is circular in cross section in FIG. 3 (a), but it may be a trapezoidal concave portion 5'as shown in FIG. 3 (c), and the shape thereof is not particularly limited. In the case of a trapezoidal concave portion 5 ', for example, carbon fiber 6'can be inserted and reinforced.

[0006]

[Effect] The upper and lower sides of the I-shaped locking hole 2 are formed as thick portions 4, and the reinforcing groove 6 or 6'made of a hard dissimilar material such as a metal rod is provided in the concave groove 5 or 5'provided in the thick portion. It was fitted and reinforced to serve as a locking portion for the end fitting of the load clamp. As a result, it becomes easy to form the locking hole for the load fastening tool provided on the luggage compartment side of the hollow extruded material-made fan member, and the strength of the portion where the end fitting of the load fastening tool engages becomes stronger than before. It was
