Description

[Detailed Description of the Invention] This invention relates to a device for connecting the floor material and side frame of a truck bed.

In the loading platform of a truck, a flooring material made of extruded aluminum material that also serves as a horizontal joist, that is, a flooring material with legs corresponding to one or more horizontal joists integrally molded on the lower surface of the floor plate part, is placed on top of the vertical joists and perpendicular to the horizontal joists. When a loading platform floor is formed by arranging multiple pieces in the direction of No. Moreover, the upper surface of the side frame preferably does not protrude above the floor surface for convenience of drainage and cleaning of the floor surface of the loading platform. Furthermore, since a tilter is generally mounted on the side frame, it must be particularly firmly connected to the flooring so as to withstand its rotation.

This invention attempts to provide a connecting device for flooring and side frames that meets the above requirements.

For the above-mentioned purpose, this invention is such that the flooring material 3 which is made of extruded aluminum and which also serves as a horizontal joist and which has one or more leg parts 8 and 9 integrally formed on the lower surface of the floor plate part 7 is arranged on the vertical joists 2 to form a loading platform floor. In the truck loading platform, side frames 4, 4' made of profiled material are arranged on both the left and right sides of the loading platform floor 1, and the side frames 4, 4' are slides having a cross section which is opened inward. a vertical wall 14 having a groove 13;
The flooring mounting portions 16, 16' have a horizontal mounting plate 15 extending inward from the lower end thereof, and the end of the flooring 3 is placed on the horizontal mounting plate 15, and the lower end of the leg 9 is mounted on the horizontal mounting plate 15. It is fixed with bolts and nuts 18, and the T-shaped base 17a at one end of the flooring connection piece 17 is slidably fitted into the slide groove 13, and the inward protrusion 17b of the flooring connection piece 17 is inserted into the slide groove 13. The gist of this device is a connecting device for a side frame and a floor material of a truck loading platform, which is abutted against the lower surface of the floor plate portion 7 of No. 3 and fixed thereto with screws 19.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

Figure 1 shows a truck loading platform.The loading platform floor 1 is constructed of vertical joists 2, 2 made up of a pair of left and right channel members fixed on a chassis.
It is formed by arranging a large number of horizontal joists and flooring materials 3 made of extruded aluminum materials. And, on both the left and right sides of this loading platform floor 1,
Side frames 4, 4' also made of extruded aluminum are arranged and fixed to the flooring 3,
A side tilting mechanism 5 is attached to the upper part of the outer surface of the housing by means of a hinge 6 so that it can be raised and lowered.

As shown in FIG. 2, the floor material 3 is provided with one or more supporting legs 8 having an inverted T-shaped cross section on the lower surface of the upper floor plate portion 7, and with a step-shaped support leg portion 8 on the lower surface of one side edge. The bent mounting legs 9 are provided, and the fitting protrusions 10 for joining formed on both side edges of the floor plate part 7 and the fitting recesses 11 of the corresponding shape are fitted one after another, so that the adjacent Floor materials 3 and 3 are joined together. A horizontal mounting plate portion 9a projecting outward from the lower end of the mounting leg portion 9 is fixed to the upper wall of the vertical joist 2 by bolts and nuts 20.

As shown in FIG. 3, the side frame 4 includes a main body portion 12 having a substantially U-shaped cross section, and a flooring attachment portion 16 integrally formed at the tip of the upper wall thereof. This flooring attachment part 16 includes a vertical wall 14 having an inwardly opened slide groove 13 in the shape of a cross section on its upper part;
It consists of a horizontal mounting plate 15 extending inward from its lower end, and a T-shaped base 17a of a plurality of flooring connecting pieces 17 separately formed in the slide groove 13.
is slidably fitted into the horizontal mounting plate 1.
5, the end of the flooring 3 is placed on it, and the mounting plate 9a at the lower end of the mounting leg 9 is attached to the bolt/nut 1.
It is fixed at 8. The floor material connection piece 17 connects each floor material 3
It is arranged corresponding to the T-shaped base 17a.
An inwardly protruding portion 17b having a generally inverted L-shaped cross section and protruding inwardly from the bottom is brought into contact with the lower surface of the floorboard portion 7 of the flooring 3, and is fixed thereto from above with screws 19.

In the embodiment shown in FIG. 3, the vertical wall 14 of the flooring attachment part 16 in the side frame 4 is suspended from the top wall tip of the U-shaped hand body part 12, and when the frame is attached, The upper surface of the U-shaped main body part 12 is set to be flush with the upper surface of the floor material 3 or less, but as in the modification shown in FIG. ' may be formed to protrude above the upper surface of the U-shaped main body portion 12, and the upper surface of the main body portion 12 may be set at a lower position than the upper surface of the flooring material.

Since this invention has the above-mentioned configuration, the side frames 4,
4' can be attached easily and reliably, and the connection between the side frames 4, 4' and the floor plate part 7 of the floor material 3 is performed on the lower surface side of the floor plate part 7 via the floor material connecting piece 17. Therefore, no protrusion or bulge is formed on the upper surface of the floor plate portion 7, and therefore, there is no problem that water or dirt tends to accumulate on the upper surface of the loading platform floor 1. In addition, the side frames 4, 4' have flooring attachment parts 16,
The horizontal mounting plate 15 of 16' is fixed to the leg part 9 of the flooring 3, and the upper end part is also attached to the flooring part 7 with the connecting piece 17.
Since the side frames 4 and 4' are integrally fixed with screws 19 through
Even if a relatively large outward force is applied to the upper part due to the rotation of the side frames 4, 4'
The upper part does not deform outward, maintains strong mounting strength, and is highly durable. Furthermore, since the T-shaped base 17a of the flooring connecting piece 17 is slidably fitted into the slide groove 13 of the side frames 4, 4', the connecting piece itself can be easily attached to the frame. Of course, it has the effect that it can be easily aligned and screwed to the position of the screw hole on the side of the flooring material 3, and that workability is good.
