[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a truck floor structure of a truck having a guide rail having a hat-shaped cross section on a lateral joist of a carrier for installing a cargo handling auxiliary device such as a roller conveyor. is there.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS. FIG. 5 is a plan view of a carrier floor of a truck equipped with a cargo handling assisting device. Reference numeral 1 denotes a roller conveyor as a cargo handling assisting device, which is installed on a guide rail 3 having a hat-shaped cross section and provided on a loading platform 2. The roller conveyor 1 is moved up and down by a mechanical or pneumatic elevating device provided below the conveyor. FIG. 6 shows an AA cross section of FIG. Horizontal joists 5 are fixed to the chassis 4 of the vehicle at appropriate intervals perpendicular to the chassis 4. At least two guide rails 3 are fixed on the horizontal joist 5 at intervals along the longitudinal direction, and the upper surface of the flange 3a of the guide rail 3 and the floor surface composed of the floor plate 6 are flush with each other. It is arranged to be.

The guide rail 3 is relatively deeply formed because a cargo handling assisting device such as a roller conveyor 1 can be protruded and retracted from the upper surface of the flange. Therefore, when the floorboards 6 are arranged alongside the guide rails 3, spacers 7 are interposed between the heavy wooden floorboards 6 and the horizontal joists 5 to reduce the weight of the entire floor. Action was being taken. The installation of the spacer 7 was an operation requiring time and labor. In the conventional guide rail 3 structure, when the guide rail 3 is mounted on a van-type vehicle, the height of the luggage compartment is reduced by the relatively large depth of the guide rail 3, so that the van-type vehicle can be mounted. Load capacity was affected.

[0004]

SUMMARY OF THE INVENTION In view of the problems of the prior art, a spacer is not required between the floorboard and the horizontal joist, the mounting is easy, and the inner height of the packing box is increased. The present invention provides a cargo bed structure having a rail for a cargo handling assisting device capable of carrying a cargo.

[0005]

[Means for Solving the Problems] Chassis 4 of truck
A horizontal joist 5 arranged above, a wooden floor 6 fixed to the upper surface in a direction perpendicular to the horizontal joist, and a cargo handling assist device such as a roller conveyor 1 disposed between the wooden floors 6 appear and disappear. At least two rows of guide rails 3 for possible mounting
In the luggage carrier floor constructed by the above, the horizontal joist 5 is inserted into the upward recess 8 formed by pressing the flanges 5c on both sides of the cut 5a to the lower end level of the cut 5a provided at the top of the web 5b of the horizontal joist 5. The upper guide rail 3 is seated and fixed. An inverted T-shaped horizontal joist 5 'arranged on the chassis 4 of the truck and a wooden floor 6 fixed to the upper surface thereof in the front-rear direction orthogonal thereto.
And at least two rows of guide rails 3 arranged between the wooden floor members 6 and for allowing loading and unloading assisting devices such as the roller conveyor 1 to protrude and retract. The transverse joist is inserted into a concave portion 9a formed by pressing a band plate 9 separate from the web 5b 'into a notch 5a' provided at the upper end of the web 5b '. The guide rail 3 on 5 'is seated and fixed. Further, a downward recess 11 is provided below the horizontal joists 5 and 5 ′, and the recess 11 is located on the upper surface of the chassis 4.

[0006]

Embodiments will be described with reference to FIGS. 5 is a horizontal joist (cross member) of the vehicle. Reference numeral 6 denotes a bed plate provided on the horizontal joist 5 and reference numeral 3 denotes a guide rail. The roller conveyor is placed in the guide rail 3. The roller conveyor is normally configured to descend to a position lower than the upper surface of the flange 3a of the guide rail 3, and to protrude above the upper surface of the flange 3a during cargo handling. In order to prevent the guide rail 3 from projecting too much from the upper surface of the horizontal joist 5, the top of the web 5b of the horizontal joist 5 is cut out to provide an upward concave portion 8, and the guide rail 3 is accommodated in the concave portion 8.

In order to form the upward concave portion 8, the top of the web 5 b of the horizontal joist 5 is cut out as shown in FIG. And the flanges 5 on both sides of the notch 5a
c is pressed from above to the lower end level of the notch 5a and formed as shown in FIG. FIG. 3 shows another method for forming the recess 8. This cuts out the upper end of the web 5b 'of the horizontal joist 5' having an inverted T shape to form a notch 5a '(FIG. 3 (c)). On the other hand, the separate band plate 9 is pressed so as to have a similar cross-sectional shape to the notch 5a 'of the web 5b' to form the concave portion 9a. Then, the recess 9a on the strip side is placed on the notch 5a 'on the web side, and integrated by welding 10 as shown in FIG. 3 (e). FIG. 4 shows a downward recess 1 in the lower part of the horizontal joist 5.
1 and the chassis 4 is located in the concave portion 11, whereby the height of the luggage compartment of the van-type vehicle can be further increased, whereby the loading capacity can be reduced in combination with the structure of the upper horizontal joist. Can increase.

[0008]

[Effect] The loading floor of a truck is composed of a horizontal joist 5 arranged on a chassis, a floor material fixed to the upper surface thereof, and at least two rows of guide rails for a cargo handling assisting device. The upper guide rail 3 is seated and fixed in the recess 8 provided in the horizontal joist 5. 1) The wooden floorboard can be directly mounted on the horizontal joist without a spacer, so Can significantly reduce the number of manufacturing steps. 2) In the case of a van-type vehicle, the height inside the packing box can be increased by the amount of the concave portion 8, so that the loading capacity of the luggage compartment can be increased. 3) Further, a concave portion 11 is provided in the lower portion of the horizontal joist, and the chassis 4 is positioned in the lower portion.
Together with this, the inside height of the packing box can be increased, contributing to an increase in the loading capacity.
