Description

[Detailed Description of the Invention] This invention relates to a truck tilt, that is, a wall that can be freely raised to surround the loading platform of a truck and is installed at the left and right sides and three rear edges of the loading platform.

This type of tilt panel consists of a plurality of tilt panels made of extruded aluminum, which are stacked together and connected together with the required number of connecting bolts and nuts. The panel is made of extruded material with an opening on the inside of the flap that runs the entire length of the panel, and a flat bottom cover.
Both side edges of the plate were fixed to the inner side walls of the panel on both sides of the opening by rivets, respectively.

However, this method requires a very large number of rivets, which increases the material cost, and also increases the number of man-hours required for riveting, making it extremely troublesome to manufacture the track tilter.

This idea was made to solve the above problems, and it is possible to reduce the number of rivets used to attach the lower cover and the man-hours for riveting by half, and also to firmly attach the lower cover to the lower tilt panel. This is an attempt to provide a truck tilt that allows you to do the following.

This invention will be explained below based on embodiments shown in the drawings.

In the drawing, 1 is the side part of the truck tilt; 2;
3. Reference numeral 4 designates three tilt panels made of aluminum extrusion forming the tilt side wall 1. These panels are stacked horizontally, and the adjacent middle and lower panels 3 and 4 are stacked horizontally.
Male and female fitting portions 5 and 6 provided on the joint surfaces of the same are fitted into each other.

7 is tilt panel 2. 3. 4 are integrally connected, and these are constituted by double-threaded bolts with a nut 8 fixed by welding to the upper end 7a,
They extend transversely through the middle and lower tilt panels 3, 4, respectively.

Reference numeral 9 denotes a pair of latching metal fittings attached to the lower side of the nut 8 at the upper end 7a of each bolt 7. I'm being robbed.

Reference numeral 11 designates bolt holes drilled in the horizontal walls of the middle and lower tilt panels 3 and 4.

Reference numeral 12 denotes a lower cover attachment part with an abbreviated cross section that is integrally provided on the outer edge of the lower wall 4a of the lower tilt panel 4 so as to extend downward; An upward protrusion 28 having a concave fitting groove 13 opened downward and having a hammer-shaped cross section is provided.

Reference numeral 14 denotes a lower cover made of extruded aluminum and having an abbreviated cross section. This has the same length as the lower tilt panel 4, and the lower cover mounting portion is disposed opposite to the portion 12.

A fitting convex portion 15 and a reinforcing convex portion 19 are provided in parallel to each other on the outer edge of the horizontal wall 14a of the lower cover 14, and a fitting groove 29 is provided between both convex portions 15 and 19 and opens upward.
is formed, and the fitting convex portion 15 of the lower cover 14 is fitted into the fitting groove 13 opened downward, and
The lower cover is attached by fitting the hanging wall 28a of the inner edge of the upper protrusion 28 of the portion 12 into a fitting groove 29 which is open upward.

The upper edge of the vertical wall 14b of the lower cover 14 is fixed to the lower edge of the inner wall 4b of the lower tilt panel 4 with rivets 18.

The lower edge of the inner wall 4b of the panel 4 is slightly recessed from the inner surface of the panel 4, and the vertical wall 1 of the lower cover 14
The upper edge of 4b is fixed.

The head of each rivet 18 is blue at the bottom! - It does not protrude inward from the inner surface of the panel 4, and there is no fear that the rivet 18 will damage the package.

Reference numeral 20 denotes a washer with legs that is fitted over the lower end 7b of the connecting bolt 7, and of the four legs, only one side leg 20a is made higher than the other legs.

21 is a double nut screwed to the lower end 7a of the connecting bolt 7, 22 is a spring washer interposed between the Narrow I 21 and the leg washer 20, and 23 is the lower part of the panel 4 The lower cover is attached to the outer edge of the wall 4a by a concave groove provided along the section 12, into which the high side leg 20a of the leg washer 20 is fitted, so that the washer can be easily attached during bolt tightening work. 20 is prevented from rotating.

24 is a lower frame made of extruded aluminum laminated material fixed to the peripheral edge of the truck bed, 25 is the outer surface of this,
The lower cover of the tilt side surface section 1 is attached by means of hinges attached to the portions 12 and 12 by bolts and nuts 26, respectively, to rotatably support the tilt side surface section 1.

Reference numeral 27 denotes a draining portion that is provided in a hanging manner on the outer edge of the horizontal wall 14a of the lower cover 14, and is brought into contact with the outer surface of the upper edge of the lower frame 24 of the loading platform.

In the above embodiment, the lower cover is attached at part 12.
The horizontal wall 12 a of the lower cover 14 and the horizontal wall 14 a of the lower cover 14 both have a width approximately half the width of the lower wall 4 a of the lower tilt panel 4; The width of one may be large and the width of the other may be small.

Further, the tilt side surface portion 1 is constituted by three tilt panels 2° 3.4, but of course the number of tilt panels can be combined arbitrarily.

Although only the side part 1 of the tilt tilt was explained, the rear part of the tilt tilt has the same structure as the tilt side side part 1, with the only difference being the installation location of the draining part 27 on the lower edge and the shape of the hinge. have.

Incidentally, in some cases, a tilt wall of a truck is constituted by a single tilt panel, and this invention can be similarly applied to such tilt wall.

As mentioned above, in the truck tilt system according to this invention, the lower cover mounting section 12 of the cross-sectional shape is provided in a hanging shape on the outer edge of the lower wall 4a of the lower tilt panel 4, and the lower cover mounting section 12 is provided in a hanging shape. At the inner edge of the horizontal wall 12a at the lower edge of 12, an upper protrusion 28 having a cross-sectional opening shape and having a downwardly opened fitting groove 13 is provided.
A lower cover 14 having a cross-sectional shape is disposed so as to face the lower cover 14, and a fitting convex portion 15 and a reinforcing convex portion 19 are provided in parallel to each other on the outer edge of the horizontal wall 14a at the lower edge of the lower cover 14. Both convex portions 15. - A fitting concave groove 29 opening upward is formed between the fitting projections 1 of the lower cover 14.
5 is fitted into the fitting groove 13, and the lower cover is attached to the hanging wall 2 on the inner edge of the upper protrusion 28 of the portion 12.
8a is fitted into the fitting groove 29, and the upper edge of the vertical wall 14b of the lower cover 14 is fixed to the lower edge of the inner wall 4b of the lower tilt panel 4 with rivets or the like 18. Therefore, compared to the conventional case in which both edges of the lower cover are riveted, the number of rivets 18 used to attach the lower cover 14 and the man-hours for riveting can be halved, and the truck tilting can be reduced by half. can be assembled easily and inexpensively.

Further, the fitting protrusion 15 of the lower cover 14 is fitted into the fitting groove 13 opened downward, and the lower cover is attached to the hanging wall 28 on the inner edge of the upper protrusion 28 of the portion 12.
a is fitted into the fitting groove 29 that opens upward,
Since these fitting parts are brought into contact with the top surface of the loading platform while the truck is running, there is no fear that the fitting parts will come off vertically or horizontally due to vibrations of the loading platform while the truck is running. This has the effect that the lower cover 14 can be securely attached to the lower tilt panel 4.
