Description

[Technical Field] The present invention relates to a double swing wing vehicle in which both sides of a box-shaped carrier can be opened. More specifically, the present invention relates to an L for opening both sides of the box-shaped carrier. A double-opening type with a structure in which a pair of wings with a V-shaped cross section are connected to beams that are arranged on the ceiling of a box-shaped platform and extend in the front-rear direction so that they can be rotated about one axis by multiple connecting hinges. It concerns wing cars.

(Prior Art) Conventionally, a pair of wings having an L-shaped cross section constitutes at least a part of a roof and a side wall of a box-shaped luggage carrier, and the wings can be pivoted about one axis at their roof-side ends. There has been proposed a double swing wing vehicle in which both wings of the box-shaped luggage carrier can be opened by rotating the wings upward about their corresponding rotation axes. Then, in such a double-opening wing vehicle, each wing is connected to the beam extending in the vehicle front-rear direction provided on the ceiling portion of the box-shaped carrier by a plurality of connecting hinges arranged in the vehicle front-rear direction. There is a structure in which each is connected so as to be rotatable about one axis.

By the way, in a wing vehicle having such a structure, as shown in FIG. 7, conventionally, a connecting hinge 6 for connecting the above-mentioned wings 2, 2 and the beam 4 is welded and fixed to the beam 4. It includes a side metal member 8, a wing side metal member 10 fixed to the wing 2, and a connecting pin 12 that rotatably connects the beam side metal member 8 and the wing side metal member 10, and their connecting hinges. 6 are provided independently of each other.

(Problem) And, for that reason, in the conventional double swing wing vehicle of this kind of structure, based on the weight load of the wing,
A large force acts in the peeling direction on the welded portion between the beam-side metal fitting 8 of each connecting hinge 6 and the beam 4, and the beam-side metal fitting 8 of the connecting hinge 6 and the beam 4 are caused by the force acting on the peeling method. There is a problem that the welded portion is easily broken.

Also, in a double swing wing car of this type of structure,
It is necessary to weld and fix the beam side metal fitting of the connecting hinge to the beam with high positioning accuracy. However, as described above, since the connecting hinges 6 are provided independently of each other in the related art, the connecting hinges are connected to each other. It is necessary to perform such welding work as many times as the number of the hinges 6 arranged, and therefore, there is a problem that the welding work is troublesome and takes a long time.

(Solution) Here, the present invention has been made in view of such circumstances, and the gist thereof is, as described above, in the vehicle longitudinal direction provided on the ceiling of the box-shaped luggage carrier. A pair of wings having an L-shaped cross section configured to include at least a part of a roof and a part of a side wall of the box-shaped bed with respect to the extending beam is provided to a plurality of connecting hinges arranged in the vehicle front-rear direction. A double-wing wing connected at its roof-side end so as to be rotatable about one axis, and the wings can be rotated upward about the connecting hinge to open both sides of the box-shaped carrier. In a vehicle, connecting hinges for connecting the beam and each wing, a beam side metal member welded and fixed to an upper surface of the beam, a wing side metal member fixed to each wing, and a corresponding beam side metal member. And the wing-side metal fittings are rotatably connected to each other, and the connecting hinges for both wings are provided so as to form a pair, and the beam-side metal fittings of the corresponding connecting hinges for both wings are integrally formed. A central hole of a predetermined size is provided in the central portion of a portion of the integrated metal fitting on the beam side that is welded and fixed to the upper surface of the beam, and a weld portion is further formed around the central hole. I have done so.

(Action / Effect) In such a double swing wing vehicle, the connecting hinges for both wings are provided in a pair, and the beam side metal fittings of the corresponding connecting hinges are integrally formed and welded to the upper surface of the beam. Since it is fixed, the weight load of both wings acts on both ends of the beam side metal fittings substantially evenly, and a large force is applied in the peeling direction to the welding portion between the beam and the beam side metal fitting of the connecting hinge. Is effectively prevented, and as a result, the beams and the metal fittings on the beam side of the connecting hinge are also prevented from breaking at their welds.

In other words, according to the double swing wing car according to the present invention, the mechanical strength of the welded portion between the beam and the beam side metal fitting of each connecting hinge can be substantially improved, and the durability of the welded portion can be improved. Can be greatly improved.

In addition, in the present invention, a central hole of a predetermined size is provided at the central portion of the portion of the beam side metal fitting that is welded and fixed to the beam upper surface, and the central hole is also provided around the central hole. Since the welded portion is formed, the welded portion can be effectively increased, and the above-described increase in the mechanical strength of the welded portion with respect to the beam of the beam side metal fitting is achieved even more advantageously. is there.

Further, according to the double swing type wing vehicle according to the present invention, the number of metal fittings on the beam side of the connecting hinge that connects the beam and the two wings can be reduced by half, so that the troublesome welding work of the metal fittings on the beam side for the beam can be substantially halved.
