Was. Also, in the conventional tilting hinge for mounting, since the cylindrical connecting portion into which the pivot is inserted projects outward from the outer surface of the side wall of the loading platform, for example, when traveling on a narrow road, a pedestrian or bicycle However, there is a problem that the hinge may be caught by the pivot-shaped cylindrical connecting portion of the hinge, and a large number of hinges appear on the outer surface of the side wall of the carrier, so that the appearance is very poor.

In view of the above points, the inventors of the present invention have conducted intensive studies and, in a vehicle such as a truck, have the above-mentioned swivel swingable 180 ° through a connecting member made of an extruded aluminum material on a side wall of a loading platform. A mounting device for the mounted tilt has been proposed (for example, see Japanese Patent Application Laid-Open No. 5-65081).

[0010]

In the above, first, the tilt is closed,
In other words, in a state before the opening in which the tilt combined with the loading platform side wall of the truck or the like via the connecting member stands on the loading platform, the third hinge component of the connecting member is the first hinge component of the tilt lower end. Of the third
A head having a substantially circular cross-section at the tip of the third engaging portion on the hinge component side is fitted into the concave arc-shaped guide surface on the first hinge component portion and engaged with the inward convex portion. At this time, the tapered tip of the first seal member is brought into contact with the base of the convex portion of the third overhang of the connecting member. On the other hand, the fourth hinge component of the connecting member is housed in the concave portion of the second hinge component on the upper edge of the side wall of the loading platform, and the head of the fourth engaging portion on the side of the fourth hinge component has a substantially circular cross section. The portion is fitted into the concave guide surface on the side of the second hinge component and is engaged with the inward convex portion. The tapered tip of the second seal member is in contact with the base of the convex surface of the fourth overhang of the connecting member.

The tilt can be tilted outward by 180 ° from the standing state, due to the following action.

That is, when the tilt in the upright state is tilted outward, first, the tilt and the connecting member are brought together together with respect to the side wall of the loading platform so as to have a substantially circular cross section at the tip end of the fourth engaging portion of the fourth hinge constituting portion of the connecting member. Swings about the center point (B) of the head.
In this manner, when the tilt is opened by approximately 90 ° together with the connecting member, the tapered tip of the second seal member is brought into contact with the tip of the convex surface of the fourth overhanging portion of the connecting member.

When the tilt is subsequently lowered, the connecting member can no longer rotate any more, so that only the tilt swings with respect to the connecting member. That is, the tilt after being opened by about 90 ° swings about the center point (A) of the substantially circular cross-section head of the tip of the third engaging portion of the third hinge constituting portion of the connecting member. When the tilt is further opened by approximately 90 ° with respect to the connecting member, the tapered distal end of the first seal member is brought into contact with the distal end of the convex portion of the third overhang of the connecting member.

As described above, according to the tilt mounting apparatus, the tilt opening / closing mechanism with respect to the side wall of the carrier is simplified, the tilt can be opened and closed by approximately 180 °, and the conventional hinge mounting is completely eliminated. Not required.

There is almost no gap formed between the tip of the hinge component on the tilting side and the connecting member and between the connecting member and the tip of the hinge component on the side of the loading platform. Even when this tilted truck is used in a heavy snowfall area, there is no danger of the opening and closing of the tilt caused by the adhesion of snow and ice. Rainwater, snow, ice, etc. do not enter the recess,
There is no support for the opening and closing operation of the tilt, and the occurrence of corrosion in the gap can be prevented beforehand, and the durability is excellent.

Further, in the above-mentioned tilt mounting device, the tilt and the connecting member, which are usually made of extruded aluminum members, may be simply combined with the side wall of the loading frame member. The number of installation steps can be greatly reduced, and even an amateur can perform the installation operation, and the mounting accuracy can be reliably achieved.

Further, the tilt, the loading platform side wall and the connecting member are usually made of extruded aluminum material, so that the loading tilt in a vehicle such as a truck can be reduced, and the conventional hinge is not used. There is no rust due to the hinge, and the appearance of the tilt mounting part can be improved.

As described above, not only a large number of hinges as in the related art appear on the outer surface of the tilt mounting portion of the loading side wall, but also the hinge, the connecting member, and the hinge components of the loading side wall, Since almost no gap is formed, the appearance is very beautiful and the degree of freedom of design is large, for example, at the lower end of the tilt, the connecting member and the side wall of the carrier,
As a whole, it is possible to adopt a design that gives a slightly bulging roundness to the outside, and the appearance is good and the design is excellent.

In the state before and after the opening of the tilt, the hooking portion (engagement portion) of the connecting portion between the first hinge component and the third hinge component or the connecting portion between the second hinge component and the fourth hinge component is provided. Are both large,
The mounting strength of the tilt is very large.

In addition, the mounting portion of the tilt does not protrude outwardly from the side wall of the loading platform, so that, for example, even when traveling on a narrow road, there is no possibility that a pedestrian or a bicycle will be caught by the mounting portion of the tilt. It is very secure.

The tilt is usually made of extruded aluminum hollow material, and the connecting member is made of extruded aluminum material. However, the present invention is not limited to this, and the tilt may be made of other materials. Even if the connecting member is made of other metal or hard synthetic resin,
Of course it is good.
