[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed floor structure for van type vehicles.

[0002]

2. Description of the Related Art As shown in FIG. 1, a roller rolls in a guide rail 2 having an inverted hat-shaped cross section, which is buried below the floor surface at intervals in the longitudinal direction of a loading platform 1. A cargo handling device (for example, a product name Joroda device) 3 (FIG. 3) that is movable in the front-rear direction has been conventionally used for cargo handling of van type vehicles and the like.

As shown in FIG. 3, two cargo handling devices are used as a set. Then, when the lever 4 is erected as shown in FIG. 4, the luggage placing section 5 is lower than the floor 1, so that the luggage can be placed on the floor and the cargo handling device 3 can be pulled out rearward. Further, when the lever-4 is tilted as shown in FIG. 5, the load carrying section of the cargo handling device 3 is lifted above the floor 1, so that the load on the floor can be moved.

The guide rail 2 for such a cargo handling device is
At least two articles are installed in the vertical direction of the cargo floor, and the cargo is transported by using two cargo handling devices as one set.

The conventional guide rail 2 is relatively deep in relation to the rolling roller 3a (FIG. 5), and it is a troublesome work to bury it all under the floor. It was That is, as shown in FIG. 2, the floor plate 1a thinner than the depth (H) of the guide rail 2 has a spacer 1b on the lower surface thereof so as to be flush with the guide rail 2. If the floorboard 1a is thickened and the spacer 1b is abolished, the weight of the vehicle increases, so this spacer system is inevitable.

Therefore, when assembling the cargo floor, the guide rail is used.
To attach the three members of the floor 2, the floor board 1a, and the spacer 1b or the floor board 1a and the spacer 1b to the lateral joist 6 integrally,
Work on the upper side of the loading platform 1 and work on the lower side of the loading platform are required. However, I had to keep working together.

Further, the conventional floor structure has a drawback that the weight of the vehicle increases because the floor except the guide rail 2 is made of wood.

[0008]

In view of the problems of the prior art, the assembling work of the cargo bed floor having the guide rails for the cargo handling device is simplified, and the assembling work of the cargo bed floor is performed only on the upper side of the cargo bed floor. The purpose is to be able to.

[0009]

Means for Solving the Problems A floor structure in which a floor material A with a guide rail made of an extrusion type material and a flat floor material B are fixed on a lateral joist 15 made of the same extrusion type material, and the guide rail is provided. The flooring material A has a guide rail portion 16 for guiding rollers of a cargo handling device at a central portion, and a connecting portion 1 flush with the bottom of the guide rail portion 16 on both sides thereof.
7, the connecting portion 17 has a rising portion 18 at the longitudinal edge.
And a lid attachment portion 19 which is provided above the connection portion 17 and is integrally provided on the side of the main body portion of the floor material A and parallel to the connection portion 17.
The flat floor material B has the same height as that of the floor material A with guide rails, and has the connecting portions 17 having the rising portions 18 at the edges on both sides thereof. A lid mounting portion 1 which is integrally provided on the side of the main body portion of the flooring B and is provided in parallel with the connection portion 17
9, the horizontal joist 15 has a bolt head insertion groove 21 in the upper part, and after the floor material A with guide rails and the flat floor material B are juxtaposed on the horizontal joist 15, the rising portion is formed. 18 is covered with a U-shaped cross-section washer 11 and is secured to the lateral joist 15 with bolts 10, and a lid 13 made of, for example, wood or synthetic wood is covered on the connecting portion 17 and is fixed to the lid mounting portion 19. .

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is constructed by combining a floor material with an extruded aluminum material. In FIG. 6, A is a floor material with a guide rail, B is
Is a flat floor material having a flat upper surface connected to both sides of the floor material A with guide rails. The floor material A with guide rails and the flat floor material B are connected to the horizontal joist 15 with bolts 10, washers 11 and nuts 12. The connecting portion is covered with a lid 13 made of, for example, wood or synthetic wood, which is fixed with screws 14 so as to be flush with the top surface of the floor.

The floor material A with guide rails has a guide rail portion 16 of the cargo handling device in the center, and connection portions 17 flush with the bottom of the guide rail portion 16 on both sides thereof. . The connection has a low rise 18 which engages a washer 11 having a U-shaped cross section. Reference numeral 19 denotes a lid mounting portion provided parallel to and integrally with the connecting portion 17 on the side of the main body of the floor material A with guide rails.

The flat floor material B has a flat upper surface and has the same height as that of the floor material A with guide rails, and the floor material A with guide rails is provided on both sides.
A connecting portion 17 having a rising portion 18 similar to that and a lid mounting portion 19 are provided. If necessary, a plurality of vertical ribs 20 are integrally formed inside.

The horizontal joist 15 is also made of an aluminum extruded material and has a C-shaped cross section as a whole as a known joist, but has a bolt insertion groove 21 through which the head of the bolt 10 connecting the floor materials A and B can be inserted. It is provided on the upper part.

[0014]

[Assembly of Floor Material] First, the floor material A with the guide rail and the flat floor material B are placed on the horizontal joist 15. In this case, the washer 11
The bolt holes 11a are pre-drilled at a constant pitch on the head, the bolt 10 with the head inserted into the bolt head insertion groove 21 of the lateral joist 15 is passed through the bolt hole 11a of the washer 11, and the nut 12 is lightly screwed in. The floor material A is the gap S between 11 and the horizontal joist 15.
It is supported by other means so that it is larger than the height h of the rising portions 18 of B and B (S> h).

The floor material A and the floor material B are slid from the side to bring them into contact with the bolts 10, the washer 11 is lowered, and the nuts 12 are tightened. If a packing is interposed between the rising portion 18 and the washer 11 when the nut 12 is tightened, the sealing effect is further enhanced.

The lid 13 is placed on the lid attachment portions 19 of the left and right floor members A and B. The fixing screw 14 is screwed and fixed to the lid mounting portion 19 from the floor upper surface.

FIG. 8 shows the longitudinal end structure of the floor structure.
Inside the front lower frame member 23 attached to the lower end of the front wall 22, a seal member mounting groove 24 is provided, and a seal member 25 such as a gasket is fitted into the groove, and the floor members A, B and the lid 13 are fitted. The front end of is abutted.

In the rear part, the rear lower frame member 26 is attached to the seal member mounting groove 2.
7 is provided, and a seal material 28 such as a gasket is fitted into this, and the rear ends of the floor materials A and B and the lid 13 are butted. Thus, the sealing effect at the front and rear ends is perfect.

[0019]

[Effect] The floor material A with guide rails and the flat floor material B are arranged on both sides of the bolt 10 inserted into the bolt head insertion groove 21 of the lateral joist 15 and are fixed by tightening through a U-shaped washer.
Further, the lid 13 is put on it and fixed with screws 14. As a result, it is possible to assemble the cargo bed floor by the downward work on the upper surface of the cargo bed, so that not only the workability is improved, but also the labor can be reduced. Since the floor material A and the floor material B have the same height, a spacer is not required, and since the wooden floor is replaced with an aluminum extruded material, the weight of the vehicle can be greatly reduced. By using the floor profile A and the floor profile B as standard parts, there is an advantage that the floor profile can be easily replaced when repairing a part of the floor profile. Since the lid body 13 is made of wood or synthetic wood, the top of the cargo bed becomes slippery, which is safe for workers and luggage.
