Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a guide rail mounting structure for a roller conveyor which is installed on a luggage carrier of a truck.

[0002]

[Prior art]

 This will be described with reference to FIGS. FIG. 4 is a plan view of a bed floor of a lorry equipped with a cargo handling assistance device. Reference numeral 1 denotes a roller conveyor as a cargo handling assistance device, which is installed on a guide rail 3 having a hat-shaped cross section provided on a cargo bed 2. The roller conveyor 1 is designed to be lifted and lowered by a mechanical or pneumatic lifting device 1a (FIG. 6) provided at the bottom of the conveyor. FIG. 5 shows an AA cross section of FIG. Lateral joists 5 are fixed to the chassis 4 of the vehicle orthogonally thereto at appropriate intervals. At least two guide rails 3 are fixed on the lateral joist 5 at right angles to each other along the longitudinal direction, and the upper end surface of the flange 3a of the guide rail 3 and the floor plate 6 are flush with each other. It is arranged so as to be one.

The guide rail 3 is formed relatively deep because a cargo handling assisting device such as the roller conveyor 1 can be retracted from the upper surface of the flange. Therefore, when arranging the floorboards 6 ... In parallel with the guide rails 3, a spacer 7 is interposed between the heavy wooden floorboard 6 and the lateral joist 5 to reduce the weight of the entire floor. Action was being taken. The installation of this spacer 7 was a time-consuming and labor-intensive operation. Further, 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 that much due to the relatively deep depth of the guide rail 3, resulting in a van type. It had an effect on the loading capacity of the vehicle.

[Problems to be solved by the device]

 In view of the problems of the conventional technology, a spacer is not required between the floorboard and the lateral joists, and it is easy to install, and is used for a cargo handling assistance device that can increase the inner height of the cargo box. To provide a structure of a bed floor with a rail.

[0005]

[Means for Solving the Problems]

 The roller conveyor mounting frame 10 installed on the bed floor of a van type vehicle is formed in a hat-shaped cross-section, and step portions 14 are formed at the front and rear ends in the longitudinal direction, and the step portions 14 are adjacent lateral joists 5,5. The roller conveyor mounting frame 10 is placed on the top of the roller conveyor mounting frame 10 concentrically in the front-rear direction of the floor, and the upper surfaces of the flanges 15 and 15 of the roller conveyor mounting frame and the upper surface of the cargo bed floor plate 6 are placed together. Formed flush.

【Example】

 A description will be given based on FIGS. 1 to 3. Reference numeral 10 denotes a roller conveyor guide frame according to the present invention, which is mounted between the lateral joists 5 and 5 adjacent to each other in the front and rear. A roller conveyor 11 is installed in the roller conveyor guide frame 10, and the roller is supported by a known mechanical or pneumatic lifting device 12 (see FIG. 2) shown in Japanese Utility Model Publication No. 42-7156. The conveyor frame 13 moves up and down along the inner wall of the guide frame 10.

The roller conveyor guide frame 10 has a hat-shaped cross section, and has step portions 14 at both ends in the longitudinal direction. The step portions are mounted on and supported by the upper flange 5a of the front and rear lateral joists 5. Then, the flanges 15, 15 provided on both sides of the roller conveyor guide frame 10 ride on the floor plate 6 stretched over the lateral joist 5, and are fixed from the mounting holes 16 with screws or the like. Reference numeral 17 denotes a reinforcing plate that is fixedly provided on the lower side of the step portion 14 of the roller conveyor guide frame 10, and is fixed to the web portion of the lateral joist 5 with rivets 18 or the like.

As described above, a large number of guide roller units A including the roller conveyor guide frame 10, the roller conveyor 11 supported by the conveyor frame 13 housed therein, and the elevating device 12 are prepared. Set it aside in the front-back direction between the horizontal joists 5 and 5 of the vehicle. At the time of loading and unloading, the individual guide roller units A are operated, or the entire guide roller units A are simultaneously operated to be raised to make the roller conveyor 11 operable. Conversely, when not in use, the conveyor frame 13 is lowered and stored in the guide frame 10.

[0009]

【effect】

 The step portions 14 in front of and behind the roller conveyor guide frame are placed and supported on the adjacent lateral joists 5, 5 and laid under the floor surface in an embedded state, and the roller conveyor guide frame 10 and the floor are installed. Since the surface is formed so as to be substantially flush, there is no need for a spacer between the horizontal joist 5 and the floor material as in the past, so the height between the cargo bed floor and the ceiling of the van type vehicle is increased by the spacer. In addition to being able to contribute to an increase in the cargo loading capacity, floor assembly work has also been greatly shortened and made easier.
