Various side opening doors having a structure in which a wing opening / closing door is rotatably supported with respect to a support body which is a joined skeleton support portion have been proposed.

In order to make the side-opening door light and inexpensive, the frame portion of the roof is manufactured by using a predetermined pipe material such as square pipe material and angle material, and the frame portion is waterproofed. A side opening door configured to cover the applied cloth sheet has been proposed. In this conventional side opening door, the lower edge portion of the side opening door is held in contact with a fan that is openably and closably provided at the edge portion of the loading platform,
The closed state will be maintained. Therefore, when the door is closed, an impact force acts on the contact portion between the side opening door and the fan, so that it is necessary to provide an impact absorbing member. It is also necessary to provide a weather strip at a portion where the lower edge of the side opening door abuts against the fan to prevent wind and rain from entering the luggage compartment.

[0004]

However, the shock absorbing member having at least two functions described above and the member satisfying both functions of the weather strip become very complicated and expensive. Or the impact absorbing member and the weather strip are provided.

Accordingly, the side opening door of the present invention has been made in view of the above problems, and its purpose is to satisfy both functions of the shock absorbing member and the weather strip with a simple structure. The point is to provide a side opening door.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view of a freight vehicle equipped with a wing opening / closing door that is open to the side surface common to each embodiment described below, as seen from the left rear diagonal. In this figure, on the cargo bed 2 of the freight vehicle 1, left and right wing doors 6 and 7 shown by broken lines in the figure are provided on the front and rear parts of the cargo bed 2 so as to be openable and closable on the side surfaces. Three and four
A skeleton member 5 shown by a broken line is provided between the substantially central portions of the horizontal beams, and is rotatably supported so as to function as a support for the left and right wing doors 6, 7. This skeleton member 5 ensures sufficient strength because the entire weight of the wing door acts when the wing door is in the open state, as shown in the figure, while the skeleton member 5 is slightly raised in the manufacturing process. The upper and lower surfaces of the skeletal support member are welded or spot-welded at a predetermined pitch so that the rivet joints are formed between the gate-shaped arch members on the loading platform, and the wing door is attached. The wing opening / closing door is configured so that its weight acts on the skeleton supporting member and is substantially parallel to the platform.

On the other hand, at the edges of both side surfaces along the front-rear direction of the loading platform 2, there is provided a fan 8 which is rotatably supported downward so that loading and unloading work of the loading platform 2 can be performed. It is configured to be easy. Next, FIG. 2 is a transverse sectional view showing an embodiment. In this figure, the supporting skeleton member 5
In order to support the wing opening / closing door that opens to the side so that it can be opened and closed on the cargo bed, the left frame part 17 of the wing opening / closing door is
The L is configured to open and close with respect to the skeleton member 5. In this way, the left frame portion 17 supported so as to be openable and closable
A corner portion type member 14L is fixed using rivets to a corner portion which is an arc portion having a predetermined radius R from the roof portion of L to the side surface portion. The corner-shaped member 14L is continuously formed with a second round groove portion 16 which is opened to the side as shown in the drawing so as to extend in the front-rear direction. Among these, the first round groove portion is the above-mentioned support. The frame members 5 are provided in the roof portion of the frame portion so as to be symmetrical and face each other.

On the other hand, the corner-shaped member 14L is further formed with a second round groove portion 16 so as to be positioned on the side surface portions of the left and right frame portions 17R and 17L.
At, the upper end portion of the side sheet 24 is fixedly held. FIG. 2 is a cross-sectional view in which the left wing door 7 is closed with respect to the fan 8. In the figure, the left frame portion 1
An edge part member 25L having a third round groove portion 26 that is open upward is continuously fixed below 7L, and a side surface is formed between the round groove portion 26 and the second round groove portion 16 described above. The seat 24 is stretched. In order to stretch the side sheet 24 without slack, first, the upper end of the side sheet 24 is fixed by the rod 22 press-fitted into the second round groove portion 16, and then the side sheet 24 is fixed to the third round groove portion 26. The rod member 23 is loosely inserted. After this, the lower edge 24 of the side sheet 24
Holes 24eg reinforced by eyelets are formed at a predetermined pitch in the lower edge 24a of the side sheet 24. After the ropes 31 are passed through the holes 24e in a staggered manner. In the lateral beam 17E provided in the front-rear direction from the frame 17L, the end of the side sheet 24 is fixed so that the rope 31 is fixed.

On the other hand, a lateral beam 17F is integrally provided at a portion below the lateral beam 17E and corresponding to the edge of the frame, and the above-mentioned edge-shaped member 25L is attached to the lateral beam 17F. A predetermined elastic material that is fixed to the luggage compartment and has shock absorption characteristics on the luggage compartment side (trade name:
An elastic rubber sponge 40 made of Clarite is configured to be fixed in the hole 40b by using a washer 34 and a screw 35. Further, a plate-shaped portion 25L-1 is integrally formed on the edge-shaped member 25L, and the lower end portion 40a of the elastic rubber sponge 40 is bent 8 and the plate-shaped portion 25L.
It is configured so as to be in a closed state in which it is interposed between -1.

During the closing operation of the wing door having the above construction (in the direction of arrow H in the figure), the plate-like portion 25L-1 urges the lower end portion 40a of the rubber sponge 40 to move toward the fan 8 side. As a result, the movement of the wing opening / closing door is alleviated, and after closing, the rubber sponge 40 is appropriately deformed to close the gap and provide a waterproof and windproof effect. As described above, functions such as shock absorption and waterproofing can be realized by a simple configuration in which the elastic rubber sponge 40 is interposed between the plate-shaped portion and the fan.

Incidentally, the above-mentioned mold member 25L (25R is omitted)
Is generally formed by extrusion of aluminum, but a synthetic resin material or another metal material may be used. Further, it is not always necessary to provide the mold member 25L, and a normal plate member may be fixed on the outer side of the edge of the frame, and the elastic rubber sponge 40 may be provided on the inner side of the edge of the frame. Further, instead of the fan 8, the edge of the luggage carrier 2 may be directly contacted.
