Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a device for attaching a latch holder in a tilt panel of a truck.

In this specification, aluminum is meant to include pure aluminum and aluminum alloys. Furthermore, the term "latch receptacle" shall include the latch receptacle and the corresponding latch that is attached to the tilt panel.

BACKGROUND TECHNOLOGY In general, in a truck tilt panel assembled by connecting a plurality of tilt panels made of extruded aluminum with several connecting bolts and nuts, a latch holder is attached to a predetermined location of the tilt panel by bolts and nuts. However, it is necessary to fit the bolt heads and nuts inside the panel so that they do not protrude into the inner surface of the hinge. For this reason, conventionally, the inner surface of the part of the tilt panel where the latch receiver should be attached is open, and after inserting a tool through this opening and screwing the nut onto the end of the latch receiver mounting bolt,
A cover was placed over the opening and fixed to the panel with rivets. However, in such conventional tilt panels, the mounting part of the latch holder is not hollow, so the strength of the panel is low.
Moreover, extrusion molding is not easy and there are problems in that the yield is poor. In addition, the work of attaching the cover is troublesome, and there is a risk that the swing may be twisted due to vibrations while the truck is running, causing the cover attaching rivets to come off and the cover to come off. Furthermore, since the heads of a large number of cover mounting rivets protrude from the inner surface of the flap, there is a problem that the cargo may be damaged by these heads.

Purpose of the invention The purpose of this invention is to solve the above-mentioned problems, to be able to be made from a completely hollow aluminum extrusion material, to have high strength, easy extrusion, good yield, and fastening. You can easily and reliably install the tool holder, and it has a good appearance and is highly durable. Furthermore, there are no protrusions such as rivet heads on the inside of the flap, which will cause damage to the cargo. We are trying to provide a truck tilt panel that is free of fear.

Structure of the invention In order to achieve the above-mentioned purpose, this invention is based on the invention that at least one thin section of the outer wall is installed at a predetermined location on the outer wall where the latch holder of the tilt panel made of hollow extruded aluminum is to be installed. A notch for inserting the bolt shaft is formed by cutting out a required length of this thin part from the end of the tilt panel in the length direction, and a latch receiver is cut out at the outer wall end of the tilt panel. The mounting bolt is placed so as to cover the entire notch, and the shaft of the mounting bolt is inserted through the notch and the through hole of the latch holder, and a nut is screwed to the tip of the bolt shank. The gist of this invention is a mounting device for a latch holder in a truck tilt panel, in which the tilt panel is fixed to the tilt panel.

Embodiment Next, an embodiment of this invention will be described based on the drawings.

In the drawing, the upper tilt panel 1 of the truck is made of a hollow extruded aluminum member, and two pairs of hooks are attached to the upper edge of the outer wall 2 to which the latch receivers 7 are to be attached, spaced apart from each other by a predetermined distance. Two sets of thin wall portions 3 are provided in the length direction of the outer wall 2. Then, from one end of the upper tilt panel 1, two pairs of thin wall portions 3 and strip wall portions 8, 8 between the thin wall portions 3, 3 of each set are cut to the required length, respectively. Two bolt shaft insertion notches 4, 4 are formed, and the upper tilt panel 1
A latch receptacle 7 is arranged at the end of the outer wall 2 so as to cover the entire notch 4, and each shaft portion 5a of the three mounting bolts 5 is inserted into the notch 4 and the through hole 11 of the latch receptacle 7. A latch receiver 7 is attached to the end of the upper tilt panel 1 in a protruding manner by screwing a nut 6 to the tip of each bolt shaft portion 5a. Note that a reinforcing wall 10 is provided in the hollow portion 9 of the upper edge of the upper tilt panel 1 so as to be located between the two notches 4, 4.

In the above embodiment, the latch receiver 7 is attached to the tilt panel 1, but a latch (not shown) can also be attached in the same manner.

Further, in the above embodiment, the pair of thin wall portions 3,
Although the band-shaped wall portion 8 in the middle of the three comrades is made thick, this band-like wall portion 8 may be made thin. In short, in this invention, at least one thin section 3 for forming a bolt insertion notch 4 is provided at a predetermined location of the outer wall 2 to which the latch receiver 7 of the tilt panel 1 is to be attached. It is sufficient if it is provided in the direction.

Furthermore, in the above embodiment, the upper tilt
Although the case where the head of the bolt 5 is fitted into the hollow part 9 of the panel 1 is shown, since the tightening by the bolt 5 and the nut 6 is relative, it is also possible to fit the nut 6 into the hollow part 9. good. Note that the tilt may be made by assembling a plurality of tilt panels, or may be made of one tilt panel.

Effects of the invention As described above, the device for attaching the latch holder on the tilt panel of a truck according to this invention is provided at a predetermined location on the outer wall 2 where the latch holder 7 of the tilt panel 1 made of hollow extruded aluminum is to be attached. At least one thin section 3 is provided in the length direction of the outer wall 2, and the tilt panel 1
A required length of the thin wall portion 3 is cut out from the end of the bolt shaft to form a notch 4 for inserting the bolt shaft. the mounting bolts 5
The shaft portion 5a of the notch 4 and the through hole 1 of the latch receiver 7
1, and a nut 6 is screwed to the tip of the bolt shaft portion 5a, whereby the latch receiver 7 is fixed to the tilt panel 1, and the tilt panel 1 has at least one row. Since it is made of a completely hollow extruded aluminum material having a thin wall portion 3, it has high strength and is easy to extrude, improving yield. In addition, when attaching the latch receiver 7 to the tilt panel 1, cut the thin wall part 3 from one end of the tilt panel 1 to form a notch 4 of the required length, and then tighten the bolt 5 and nut 6 to the latch receiver 7. In this case, the shaft portion 5a of the bolt 5 can be moved while being fitted into the notch 4.
The bolts 5 can be easily positioned, and the latch receiver 7 can be installed easily and reliably. In addition, since the notch 4 is entirely covered by the latch holder 7, the notch 4 is not exposed to the outside after installation, giving it a very good appearance and preventing rainwater from entering. It has excellent durability as it can prevent this. Furthermore, unlike in the conventional case, the heads of the cover mounting rivets do not protrude from the inner surface of the flap, so there is no risk of damaging the cargo.
