Abstract

PURPOSE:To increase the strength of the wing vehicle itself, and to make the wing vehicle bearable to the service for a long period, by preventing the deformation of a roof beam even though the forces of a vertical vibration, a sudden braking, the centrifugal force in a curving, and the like, in not only a stopping condition, but also in a running condition loading a baggage, are operated, and by connecting the roof beam and a floor surface with a column through a cushioning material so as to absorb the force operating in the running condition. CONSTITUTION:In a wing vehicle in which a roof beam 18 is extended between the center of the top of a front wall erected at the front end of a floor, and the center of the top of a rear door frame or a rear wall, and a roof with the L-shaped cross section is pivoted rotatable up and down to both the left side and the right side of the roof beam, the upper end of the column 4 with a cushioning member 40 placed is connected to the roof beam, and the lower end of the column 4 is connected to the floor surface. Such a structure is the specific feature of this roof beam deformation preventive device of the wing vehicle.

Description of the Related Art An ordinary wing vehicle has a roof beam stretched between the center of the top of the front wall standing at the front end of the floor and the center of the rear door frame or the top of the rear wall. Since a roof with an L-shaped cross section is pivotally mounted vertically, the roof beam with an L-shaped cross section on the left and right sides and the weight of the roof beam itself, as well as the snow, the roof beam receives a uniform load. This is not a problem if the total length of the roof beam is relatively short for a small wing car, but if the total length of the roof beam is large, such as with a wing trailer, the roof beam may be lowered and as a result the roof There were often accidents where it could not rotate up and down, and the hinges that pivotally attach the roof to the roof beams were damaged.
