Description

[Detailed description of the invention] This invention relates to a tilt panel for trucks, etc. made of hollow metal members, and is intended to significantly facilitate tilt assembly and also facilitate the attachment of hinges, latches, and other parts. This is the purpose.

Conventionally, a tilt panel made of a plurality of hollow metal sections is manufactured by screwing nuts 3, 3 onto the upper and lower ends of a long bolt 2 that passes through a plurality of metal sections 1, 1, as shown in Fig. 1. or as shown in FIG.
At the same time, there is a long nut 4 at the top end.
Many of them had a structure in which they were tightly connected by screwing them together. However, in the structure shown in Fig. 1, it is necessary to provide an opening 5 on the side of the hinge and close the opening 5 with a lid 7 using blind rivets 6 or the like after the shapes are fastened together, which requires a large amount of man-hours for assembly. There was a problem that required On the other hand, the structure shown in Figure 2 does not require any work such as blind rivets, but the head of the bolt 9 for attaching the hinge 8 or latch will protrude to the side of the tilter, making it difficult to install the truck. This is undesirable for cargo platforms such as the above, as it can cause damage to the cargo.

However, in this invention, an opening is formed at the outer end of the tilt panel, a lid piece is attached to the opening, and the end of a long bolt that fastens the hollow section is hooked to the lid piece. This simplifies assembly and eliminates the risk of exposing protrusions, thus solving the problems of the prior art.

That is, to explain this invention with reference to the embodiment shown in FIGS. 3 and 4, in a tilt panel formed by vertically connecting an upper panel 10a, a middle panel 10b, and a lower panel 10c made of hollow metal members, Long bolt 1 that penetrates each panel
The lower end corner head 11a of the bolt 11 is engaged with the retaining groove 13a of the flat cover piece 13 attached to the lower end opening 12 of the lower panel 10c.
A threaded portion 14a of a long nut 14 inserted from above the upper panel 10a is screwed into the upper end threaded portion 11b, and by tightening the long nut 14, the panels are tightly connected to each other. The lid piece 13 is made of a metal profile with fitting grooves 15 formed on the upper sides of both sides,
The fitting groove 15 has an opening 12 in the lower panel 10c.
Fitting protrusions 16 provided on both side edges of the panel are designed to fit and engage, so that the two are firmly connected at the same time as the panel is fastened together. Reference numeral 17 in the figure is a hinge for connecting the above-mentioned tilt panel and loading platform 18, and before attaching the lid piece 13, bolts 19,
It is attached by a nut 20.

In the embodiment shown in FIG. 5, an opening 21 is also provided at the upper end of the upper panel 10a, a flat cover piece 22 is attached to the opening 21, and the upper end thread portion 11b of the long bolt 11 is threaded. The matching long nut 14 is inserted into the panel by passing through the lid piece 22. Similarly to the above, the lid piece 22 also has fitting grooves 2 on the lower sides of both sides.
3, the upper panel 1
The fitting protrusions 24 on both side edges of the opening 21 of 0a fit and lock. In the figure, reference numeral 25 denotes a latch that is attached to the outer wall of the upper panel 10a with bolts 26 and nuts 27, and is attached before the lid piece 22 is attached.

That is, according to this invention, the ends of the long bolts for fastening the panels of the tilt panel formed by connecting a plurality of hollow panels are hooked to the lid piece attached to the opening at the lower end of the tilt panel. The lid pieces are fixed at the same time as the panels are fastened together, eliminating the need for riveting the lid pieces, facilitating assembly of the panels, and eliminating the need to form protrusions on the outside of the panels.

In addition, since the square head of the long bolt is hooked into the locking groove of the lid piece, it is easy to tighten the long bolt.
And there is little risk of it coming loose during use.
