[0007]

[Embodiment 1] The present invention has a construction in which an extruded mold material made of aluminum is combined with a cargo bed floor, and this is directly fixed on a vertical joist. In FIG. 1, A is a cargo bed floor of a van type vehicle, which is arranged side by side in a lateral direction and is fixed to a joint between the cargo bed floor materials 1 having a flat upper surface and the adjacent cargo bed floor materials 1 and 1 or synthetic wood. It is composed of a connecting portion lid body 2 and a vertical joist 3 made of. 4 is a chassis. As shown in FIG. 3, the adjacent floor base materials 1 and 1 are connected to the vertical joist 3 with bolts 5, washers 6, and nuts 7. A lid 2 made of wood or synthetic wood is covered on this connection portion, and is fixed to the cargo bed floor material 1 with a screw 8 so as to be flush with the upper surface of the cargo bed floor material 1.

The bed floor material 1 has a hat-shaped cross section in the main body and the connecting portions 9 on both sides. The connecting part 9 has a low rising part 10 on its side edge for engaging a washer 6 having a U-shaped cross section. Reference numeral 11 denotes a lid attachment portion that is provided parallel to and integrally with the connection portion 9 on the side of the main body portion of the cargo floor material 1. Reference numeral 12 denotes one or more intermediate leg portions provided in the central portion of the luggage carrier flooring material 1 having a hat-shaped cross section, and the lower end 12a thereof is flush with the lower surface of the connecting portion 9. As is clear from the figure, the main body portion and the intermediate leg portion 12 of the bed floor material 1 are tall and are directly placed on the vertical joist 3. That is, it can be seen that the conventional type of horizontal joist (cross member) is also used. Reference numeral 12b is a short reinforcing rib integrally provided between both side portions of the bed floor material 1 and the intermediate leg portion 12 or between the intermediate leg portions.

The vertical joist 3 is also made of aluminum extruded material and has a C-shaped cross section as a whole like the known joist, but has a bolt head insertion groove 13 through which the head of the bolt 5 for connecting the bed floor material 1 can be inserted. It is provided on the upper part. 14 is a hanging edge provided on both sides of the lower part of the vertical joist 3, and is an upper flange 1 of the chassis-4.
It has an interval that fits exactly in 5.

Reference numeral 16 is a front cargo bed floor material fixed to the front side frame member 17. The front part of the bed floor material 16 is fixed to the lower frame member 17 with bolts 18 and screws 19 on the front side, and the connection part 9 having the same structure as the connection part 9 of the flat bed material 1 is provided on the back side. .

The rearmost part of the cargo bed is connected to the rear lower frame member 21 as shown in FIG. The rear lower frame member 21 is also made of an aluminum extruded material, and has a lid attachment portion 11 'for attaching the connection lid 2.
And a connecting portion 9'is provided. The connecting part 9'is provided with a low rising part 10 'on its side edge.

FIG. 6 shows a side structure of the cargo bed floor A. Reference numeral 22 denotes a lower side frame member, to which a side wall 23 is attached. Two
An L-shaped bracket 4 is fixed to the lower frame member 22 with bolts 25. In addition to this, the side ends of the bed floor material 1 are bolts 2
It is fixed at 6. Further, the side ends of the cargo bed floor material 1 and the connecting portion lid body 2 are fixed to the lower side frame material 22 with screws 27.

[0013]

[Assembly of flooring material] First, the loading platform flooring material 1 is placed on the vertical joist 3. In this case, as shown in FIG. 7, bolt holes 6a are previously formed in the washer 6 at a constant pitch, and the bolt 5 having the head inserted in the bolt head insertion groove 13 of the vertical joist 3 is inserted into the bolt hole 6a of the washer 6.
The nut 7 is lightly screwed in and is supported by other means so that the gap between the washer 6 and the vertical joist 3 is larger than the height h of the rising portion 10 of the bed floor material 1 (S > H).
If the width of the washer 6 is made slightly wider and the bolt holes 6a are elongated holes, the floor material mounting position can be finely adjusted in the width direction.

The bed floor material 1 is slid from both sides of the bolt 5 so that the rising portion 10 is in contact with the bolt 5, and the washer 6 which is being supported is lowered and the nut 7 is tightened. When tightening the nut 7, the rising portion 10 and the washer 6
If a packing (not shown) is interposed between and,
The sealing effect is greater.

The lid 2 is placed on the lid mounting portions 11 of the left and right cargo floor materials 1 and 1. The fixing screw 8 is screwed and fixed to the lid mounting portion 11 from the floor upper surface.

[0016]

[Embodiment 2] FIG. 8 shows another embodiment of the bed floor material. In this example, the width of the bed floor material 1'is wider than that in the previous embodiment. That is, since there are two intermediate legs 12, the gap is too large only with the lid 2 on the connecting portion. Therefore, another wood lid 2'is provided between the connecting portions. As a matter of course, the lid attachment portion 11 ′ is integrally formed so as to straddle between the left and right intermediate leg portions 12.

[0017]

[Effect] The bed floor material 1 is arranged on the vertical joist 3 so as to be orthogonal to this,
The bolt having the head inserted into the bolt head insertion groove 13 of the vertical joist 3 is made to face upward so as to protrude between the adjacent load carrier floor materials 1 and 1,
Since the washer 6 is covered and the nuts are tightened, the work of assembling the load floor can be performed by the downward work on the upper surface of the load floor A.
For this reason, not only the workability is improved, but also the labor can be remarkably reduced. Since the lid 2 made of wood or synthetic wood having a relatively high friction coefficient is laid on the connecting portion of the adjacent floor materials, the luggage does not move on the bed A, and it is safe for the operator. The structure of the loading platform A is fixed with bolts and nuts,
Further, since the fixing work can be performed on the surface of the cargo bed floor A, even if the floor material is damaged, it can be easily replaced.
