Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a door used for a door of a vehicle such as a transport vehicle, and more particularly, to a door that is lightweight and has excellent heat insulation.

[0002]

[Prior art]

 Conventionally, doors for vehicle gates have a thick core material on the front side, a plastic or aluminum plate on the back side, and a spacer made of metal such as iron or aluminum passed between them. Then, a foaming material such as urethane foam was filled by in-situ foaming.

[0003] However, such a conventional door increases the total weight when the thick plywood or spacer is bitten, which makes the door opening and closing work cumbersome, increases the vehicle weight, and lowers fuel efficiency and economical efficiency. Inferior.

[0004] Furthermore, the heat conductivity of the bolts and nuts for stopping the spacers is high, and when they are connected to the front plate and the back plate, the heat inside the refrigerator is transferred, which causes a drop in the heat insulating effect. .

[0005] Furthermore, in order to mount a spacer on a plywood plate, it is necessary to repeat the operation of drilling a hole in the plywood plate and screwing it with a bolt and nut, but this work is unexpectedly troublesome and requires a high work efficiency. Had dropped significantly.

[0006]

[Problems to be solved by the invention]

 The present invention has been made based on the above situation, and aims to improve the workability while reducing the weight and insulation of the door.

[0007]

Means for Solving the Problems The door for the present invention has a front plate and a back plate formed of at least one material selected from the group consisting of aluminum, galvanium, stainless steel, and FRP. A door plate is formed by sandwiching a foam therebetween, and an abutting member comprising a hook-shaped portion and a rising piece portion for holding an elastic packing material such as rubber at an end of the door plate. Is formed of a metal such as aluminum, and an end member formed of a plastic such as an L-shaped polypropylene is disposed on one side.

[0008]

[Embodiment of the invention]

 Reference numeral 1 denotes a surface plate, which is formed of a thin metal plate of aluminum, galvanium, stainless steel, or plastic such as FRP, and has a thickness of about 0.5 to 2.0 mm. Reference numeral 2 denotes a back plate, which is formed of the same light metal material as the front plate 1 or a plastic rich in steel and has a thickness of about 0.5 to 2.0 mm.

Reference numeral 3 denotes a foamed material provided between the front plate 1 and the back plate 2 such as expanded styrene or urethane foam, which is rich in heat insulation. The thickness is about 50 to 100 mm. Then, the front plate 1, the back plate 2 and the foam 3 are integrated with each other via an adhesive. For example, a two-component adhesive is applied and the three members are pressed by a press or the like. The door plate 4 is formed by bonding.

An L-shaped hook 5a and a packing material 5c made of an elastic material such as rubber are held at the upper end of a door plate 4 having a front plate 1 and a back plate 2 disposed on both sides of the foam body 3. The striking member 5 including the rising piece 5b is formed of a metal such as aluminum. The hook-shaped portion 5a and the rising piece 5b are integrally formed. An end member 6 made of an L-shaped plastic such as polypropylene or vinyl chloride is provided so as to be different from the abutment member 5 to cover the end of the foam 3. The end member 6 is provided with a mountain-shaped packing material 6a as necessary. Similarly, the lower end portion is formed of a butting member 5 comprising an L-shaped hook-shaped portion 5a and a rising piece portion 5b for holding an elastic packing material 5c such as rubber, made of metal such as aluminum. An end member 6 made of plastic such as L-shaped polypropylene is provided. The same applies to the side end portion where the left and right doors intersect at the center of the door (see FIG. 2) and the side surface portion that contacts the left and right side wall portions (see FIG. 3).

In order to arrange a lock or the like for opening and closing the door on the surface plate 1, as shown in FIG. 4, a backing plate 7 is fixed to the inside of the surface plate 1 in advance by bonding or the like, and Fix the lock 9 with the bolt and nut 8.

Next, the operation of this embodiment will be described. A door plate formed by sandwiching a foam between a front plate and a back plate made of a thin metal such as aluminum or galvanium or a plastic is extremely lightweight. The door can be easily opened and closed, and the fuel consumption during traveling becomes economical.

In addition, since the end member 6 is provided separately from the abutment member 5, it can be freely adjusted even when the thickness of the foam 3 changes, and the foam 3 has a thickness necessary for heat insulation. The body 3 can be set freely.

Further, the abutting member 5 and the end member 6 can have the same shape at the ceiling, the bottom, the center intersection, and the left and right ends of the door, so that efficient production is possible. Is possible.

[0015] Since the bolt and nut do not penetrate between the front plate and the back plate, there is no substance having a high thermal conductivity, and the foam continuously forms a layer in the middle, so that the heat insulating effect is obtained. Is high.

The door plate is formed by bonding the foamed material between the front plate and the back plate with a press or the like via an adhesive, so that there is no need to provide a spacer or the like, that is, to fix the spacer. This eliminates the need for each drilling and screwing of bolts and nuts, thus saving labor in the production work.

[0017]

[Effect of the invention]

 Compared with the conventional plywood door, the door for the present invention according to the above configuration and operation is extremely lightweight, facilitates opening and closing of the door, improves fuel efficiency, has a high heat insulating effect, and has a bolt nut and nut. The production work without screwing work is a device with practical effects such as extremely labor saving.
