[Industrial applications]

 The present invention relates to a double-cab type truck that can be used as a mobile office at a construction site or the like.

[0002]

[Prior art]

 Conventionally, when heading to a relatively small construction site, people were transported by one-box type vehicles and materials were transported by truck. In the above-mentioned one-box type vehicle, the backrest of the rear seat is provided in multiple steps so that it can be tilted forward, and the table with one side edge supported on the upper rear part of the backrest according to the forward tilt angle of the backrest. A support structure for a vehicular table that is configured to be in a horizontal state is disclosed (Japanese Utility Model Laid-Open No. 59-83637). The table is supported by an arm or stay in a horizontal state according to the forward tilt angle of the backrest. In addition, a front seat that is rotatable to face the rear seat is provided in front of the rear seat, and an auxiliary seat is provided behind the rear seat. In this support structure, when the front seat is rotated so as to face the rear seat and the backrest of the rear seat is tilted forward, the front seat and auxiliary seat occupants are sandwiched across the horizontally supported table. Since they can face each other across the table, the habitability in the passenger compartment can be improved and they can be used not only for transporting personnel but also as a resting place.

[0003]

[Problems to be solved by the device]

 However, the transportation of personnel and materials by the above-mentioned one-box type vehicle and truck requires two parking spaces at the construction site, and there is a problem that a large parking space must be secured. Further, in the vehicle table support structure provided on the back seat of the one-box type vehicle, the one-box type vehicle has a narrow inner width, which makes it difficult to open a large drawing and hold a meeting. . Furthermore, since there is a rear seat below the table, seated persons in the front seats and auxiliary seats cannot extend their legs to the bottom of the table, and there is a problem that they must have a meeting in a cramped position. It was When trying to slide the front seat away from the table in order to eliminate the tightness of the feet, there was also the problem that the steering wheel interfered and it was not possible to slide.

The object of the present invention is to allow a large drawing or the like to be easily spread on a partition member fixed in a horizontal state, so that a seated person can have a meeting or a meal in a comfortable posture and can be constructed. It is to provide a double-cab type truck that doubles as a mobile office and can minimize the parking space on site.

A method of using the double cab type truck configured as described above will be described. When arriving at a construction site or the like and having a meeting or a meal in the cab 11 of the truck 10, first, the lock pin 41 is pulled out from the through hole 38a of the support pin 38 and the through hole 37a of the steering shaft 37, and the steering wheel. 39 is rotated from the use position to the folded position around the support pin 38, and the steering column 42 is tilted away from the driver's seat 13 around the rotation shaft 44 (FIG. 1).

Next, the upper lever 29 is pulled up to disengage the upper pin 29a from the locking hole 22d of the rotary plate 22, and the driver's seat 13 is rotated about the upper shaft 23 in the direction of the solid arrow in FIG. The seat 13 reaches the position shown in FIG. At this time, since the upper shaft 23 is eccentric to the passenger side by a predetermined distance in a state where the driver's seat 13 is oriented in the traveling direction of the truck 10, the seat cushion 13a of the driver's seat 13 is a door trim of the front side door 11b. There is no contact with 11e. When the upper lever 29 is released in this state, the upper pin 29a is urged by the spring 32 to be loosely inserted into another locking hole of the rotary plate 22, and the driver's seat 13 cannot be rotated.

Next, the lower lever 28 is pulled up to disengage the lower pin 28a from the locking hole 19a of the base plate 19, and the driver's seat 13 is rotated about the lower shaft 21 in the direction of the solid arrow in FIG. 13 reaches the position shown in FIG. When the lower lever 28 is released in this state, the lower pin 28a is urged by the spring 31 to be loosely inserted into another locking hole of the base plate 19, and the driver's seat 13 cannot rotate while facing the rear seat 14. Become. The passenger seat (not shown) is also rotated in the same manner as the driver's seat 13 to face the rear seat 14.

When the main table 33a is further rotated in the direction of the solid line arrow in FIG. 2, the stay 36b extends to fix the main table 33a in the horizontal position, and the sub table 33b is rotated in the direction of the broken line arrow. The stay 36c extends to fix the sub table 33b at a horizontal position (FIG. 1). As a result, the occupants of the front seat 12 and the rear seat 14 can face each other with the tables 33a and 33b sandwiched therebetween, and their legs can be extended below the tables 33a and 33b. Drawings, documents, etc. can be spread on the tables 33a, 33b for a detailed meeting, or lunches and tea can be placed on the tables 33a, 33b for a meal.

In the above embodiment, the seat rotating means is fixed to the upper rail of the seat track, the base plate is fixed to the base plate through the lower shaft so as to be rotatable, and the rotary plate is mounted on the rotary plate. It has an upper plate that is rotatably mounted on the passenger side via an eccentric upper shaft, and the driver's seat is centered on the upper shaft to avoid contact with the front side door when the driver's seat is rotated. After rotating 90 degrees, the lower shaft was rotated 90 degrees to face the rear seat, but this is an example. If the driver's seat does not contact the front side door, it will rotate on the base plate via the shaft. The upper plate may be directly attached so as to be movable. The above structure can also be applied to the passenger seat, which is formed symmetrically with the driver's seat. Further, although the seat track is interposed between the seat leg and the base plate in the above embodiment, the present invention is not limited to this and may be interposed between the upper plate and the seat cushion. Further, in the above embodiment, the partition member is composed of two members, the main table and the sub table, but it may be composed of only the main table.

[0021]

[Effect of device]

 As described above, according to the present invention, the seat rotating means rotates the driver's seat and the front passenger's seat respectively so as to face the rear seats, and the support extending in the vehicle width direction is higher than both seats. A shaft rotatably holds the partition member between a vertical position and a horizontal position, partition fixing means fixes the partition member at the vertical position and the horizontal position, respectively, and a support pin at the upper end of the steering shaft is at the use position. The steering wheel is fixed to the use position by rotating the steering wheel between the rear seat and the driver's seat and the front passenger seat. By rotating the partition member so as to face each other and further rotating the partition member to the horizontal position, the occupants of the front seat and the rear seat can face each other with the partition member sandwiched therebetween. As a result, the table provided in the back seat of the conventional one-box type vehicle has a small vehicle width, which reduces the width of the table. Since it is possible to secure a large width, by fixing the partition member in a horizontal state, a large drawing or the like can be easily spread on the partition member.

Further, in the conventional table support structure provided in the back seat of the one-box type vehicle, since the back seat exists below the table, the seat occupants of the front seat and the auxiliary seat cannot extend their legs. In comparison, in the present invention, since there is nothing under the partition member fixed in the horizontal position, the seated person can extend his / her legs and have a comfortable posture for a meeting or a meal. Furthermore, compared with the conventional one-box type vehicle and two trucks, the transportation of personnel and materials, only one parking space is required, and the parking space at the construction site can be minimized. it can.
