DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilt of a truck, and more particularly to a connection structure with an end post.

[0002]

2. Description of the Related Art There is a truck tilt which connects a suitable number of hollow extruded aluminum members to form a panel (commonly called an aluminum block tilt).
This aluminum block tilt has a type in which an appropriate number of aluminum extruded shapes are integrally formed with long bolts, and a type in which aluminum extruded shapes are fitted to each other.
In each case, the open end of the longitudinal end is closed by the end post.

[0003] By the way, when such block tilts are often used for open-sided box-type trucks (commonly called wing vehicles), high watertightness is required in order to prevent the load from being contaminated by rainwater or the like. Conventionally, a sealing compound is applied as a sealing material 2 to the joint of the hollow member 1 as shown in FIG. 4, for example, or the block tilt body 3 and the end post 4 are rivet 6 as shown in FIG. In the case of connection, a gap between the block tilt main body 3 and the end post 4 is filled with a sealing compound 2 as a sealing material 2, or a wooden or metal plate 5 is stuck to the indoor side of the block tilt.

[0004]

The above means not only requires a great deal of work, but also requires the rivet 6 to connect the block tilting body 3 and the end post 4 with the rivet 6. However, it was difficult to prevent contamination of the load by rainwater or the like because rainwater and the like entered the room.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned disadvantages of the prior art, and to provide not only rainwater which is likely to enter into the room from the connecting portion between the tilting body and the end post by a panel formed by connecting hollow materials, but also hollow Rainwater that intrudes into the hollow material from the connection between the materials and flows along the connection with the end post can be reliably prevented from entering the room, improving the water tightness, and the rainwater on the load An object of the present invention is to provide a truck tilt that can prevent contamination.

[0006]

According to the present invention, in order to achieve the above object, a plurality of hollow members are connected to form a panel,
In the track tilting in which the U-shaped cross section of the end post having the U-shaped cross section at the open end of the longitudinal end of the panel is fitted, grooves are respectively formed at the inner corners of the U-shaped cross section of the end post. The gist of the invention is that a groove is provided, and a sealing material is provided on both of the grooves, and the sealing material is interposed between the inner and outer walls of the panel and the inner corners of the U-shaped section of the end post.

According to the present invention, since the sealing material is interposed between the inner and outer walls of the panel and the inner corners of the U-shaped section of the end post, it flows on the outer surface of the panel and enters the room from the overlapping portion of the panel and the end post. Not only the rainwater that is about to enter, but also the rainwater that penetrates into the hollow material from the connection part of the hollow material and flows along the connection part, because the sealing material is interposed between the inner wall of the panel and the end post. Intrusion can be more reliably prevented.

In addition, since the sealing material is provided in the groove, even if the panel is inserted deeply into the U-shaped section, the thickness or amount of the sealing material can be kept constant, and the sealing material is extremely compressed or pushed out. Even if it is removed, the sealability is not impaired, and the watertightness can be maintained satisfactorily.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a cross-sectional plan view of a main part of a track tilt embodiment of the present invention, FIG. 2 is an exploded perspective view of the same, and FIG. 3 is a plan view of an end post of the main part of the same. To explain, as shown in FIG. 2, a hollow member 7 composed of a plurality of extruded aluminum members is used.
Are connected to form a panel 8 serving as a tilt body.

The panel 8 is commonly called an aluminum block tilt, and the connecting means includes a type in which the hollow member 7 is integrally formed by long bolts and a type in which the hollow members 7 are fitted to each other. .

The panel 8 according to the present invention also has a track tilt.
The end section 10 having the U-shaped section 9 is fitted to the open end of the longitudinal end of the section.
As shown in FIG. 3, grooves 11a and 11b are formed in the corners of the inner surface of the U-shaped section 9 as the shape of the end post 10, respectively. The size of the grooves 11a and 11b is determined by the sectional structure of the panel 8, and is, for example, 4 mm wide and 2 mm deep.
It is about.

FIGS. 1 and 2 show the grooves 11a and 11b.
The sealing material 12 is attached as shown in FIG. In this case, the sealing material 12 is provided on both of the grooves 11a and 11b. Examples of the material of the sealing material 12 include a sponge-like solid packing, a paste-like material that maintains flexibility over the entire use period of the truck, and the like.

By mounting the sealing material 12 in the grooves 11a and 11b as described above, a necessary amount of the sealing material
Can hold 12. That is, since the open end of the panel 8 is fitted into the U-shaped section 9 of the end post 10 by providing the grooves 11a and 11b, even if the panel 8 is inserted deeply into the U-shaped section 9, the sealing is performed. The thickness or the amount of the material 12 can be kept constant, and the sealing material 12 is not excessively compressed or extruded, so that the sealing property is not impaired and the watertightness can be maintained well.

When the open end of the panel 8 is inserted into the U-shaped section 9, the gap between the end of the inner and outer wall of the panel 8 and the inner corner of the U-shaped section 9 of the end post 10 is maintained. The sealing material 12 is interposed between the panel 8 and the outer surface of the panel 8 to prevent rainwater or the like from flowing into the room from the overlapping portion of the panel 8 and the end post 10.

Further, rainwater that flows into the hollow member 7 from the connection portion of the hollow member 7 constituting the panel 8 and flows along the connection portion with the end post 10 into the room, or the end post 10 is attached to the panel 8 It is also possible to prevent rainwater from entering the room from the rivet fastening portion when riveted.

Further, by holding the sealing material 12 in the grooves 11a and 11b, the sealing performance is not impaired even if vibrations, twists, and the like are generated by the running of the truck.

In the embodiment of the present invention, since the hollow member 7 located at the upper end of the panel 8 is wide, the end post 10 has a shape in which the inside of the upper end of the U-shaped section 9 is cut out. However, the form of attachment of the end post 10 to the panel 8 is not limited to this, and can be applied to various types.

[0018]

As described above, according to the track tilt of the present invention, not only the rainwater which tries to enter the room from the connecting portion between the tilt main body and the end post formed by connecting the hollow members, but also the hollow Rainwater that intrudes into the hollow material from the connection between the materials and flows along the connection with the end post can be reliably prevented from entering the room, improving the water tightness, and the rainwater on the load Pollution can be prevented.

The present invention is particularly effective when used in a box-type truck (commonly called a wing car) using an open side with a block tilt.
