Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a flip-up open / close roof structure for a freight vehicle.

(B) Conventional Technology Conventionally, as an example of a refrigerating vehicle as a freight vehicle having a flip-up open / close roof, one having a basic configuration similar to that shown in FIGS. is there.

That is, in the refrigerating vehicle, the base end edges of a pair of left and right open / close roofs are pivotably pivoted between the front wall and the rear wall in the front and rear sides of the loading platform so that the left and right sides of the loading platform can be raised. The base edges of the sliding doors are pivotally attached to the side edges so that they can stand and fall freely, and the upper and left and right sides of the front and rear walls can be opened and closed by the sliding doors and the opening / closing roof.

Then, as shown in FIG. 9, the opening / closing roof (a) connects the ceiling surface portion (b) and the side surface portion (c) through a connecting portion (d) formed in a quarter-arc shape in cross section. And is formed in a substantially inverted L-shape in cross section.

(C) Problem to be solved by the invention However, in the structure of the opening and closing roof, one end of the ceiling surface part (b) and one end part of the connecting part (d) are assembled with rivets (e) at the time of assembly. There is a problem in that the other end of the connecting portion (d) and the one end of the side surface portion (c) must be connected by a rivet (e) or the like, which is troublesome for such connecting work. It was

Therefore, it has been desired to simplify the assembly structure for improving the work efficiency.

Therefore, it is conceivable to directly connect the ceiling surface portion (b) and the side surface portion (c) without interposing the connection portion (d), but the connection point is the ceiling surface portion (b) and the side surface portion (c). In order to be located in the corner formed by the rivet, it must be riveted vertically inward or horizontally outward from the inside of the corner, but such tools must be used to rivet vertically upward or horizontally outward. However, there was a problem that the work efficiency decreased.

(D) Means for Solving the Problems In the present invention, therefore, a substantially inverted L-shaped cross section is formed by the ceiling surface portion and the side surface portion between the central portions of the upper surfaces of the front wall and the rear wall that are erected on the front and rear sides of the loading platform. In a flip-up open / close roof structure for a freight vehicle in which the base end edges of a pair of left and right open / close roofs formed in the above are pivotably attached, a fitting projection and a fitting projection are provided at the leading edge of the ceiling surface. An inclined connecting plate that protrudes outward from the lower surface of the base end edge of the device at an inclination angle of about 45 degrees is provided, while a fitting concave portion that can be fitted and connected to the fitting convex portion at the upper edge of the side surface portion. And a connecting plate receiving portion that can be connected by making surface contact with the inclined connecting plate, and the front end edge of the ceiling surface portion and the upper end edge of the side surface portion can be connected. It is intended to provide a flip-up open / close roof structure.

(E) Action / Effect According to the present invention, the following action / effect is produced.

That is, the fitting convex portion provided on the tip edge portion of the ceiling surface portion is fitted into the fitting concave portion provided on the upper end edge portion of the side surface portion and connected by rivets or the like, and separately on the tip edge portion of the ceiling surface portion. The opening / closing roof can be easily assembled by bringing the provided inclined connecting plate into surface contact with the connecting plate receiving portion provided on the upper edge of the side surface and connecting them with a rivet or the like.

At this time, since the inclined connecting plate is projected outward and downward from the lower surface of the base end edge of the fitting convex portion at an inclination angle of about 45 degrees,
With the inclined connecting plate in surface contact with the connecting plate receiving part, place the tool in the direction of an elevation angle of about 45 degrees that bisects the interior angle of the corner from the inside of the corner at a substantially right angle between the ceiling surface and the side surface. You can use it to easily set rivets.

In this way, the work of assembling the open / close roof can be simplified and the work efficiency can be improved.

Further, even if the fitting concave portion and the connecting plate receiving portion are provided at the tip edge portion of the ceiling surface portion, while the fitting convex portion and the inclined connecting plate are provided at the upper end edge portion of the side surface portion, the same effect as the above is obtained. Obtainable.
