It is a thing. In the manufacturing process, the structures posted on these utility models are first dispatched by workers to measure the width of the gate, then returned to the factory and assembled according to the dimensions within the factory, and then hung or carried using equipment such as a crane. Since it is configured to be attached with the following problems, it has the following problems in production.

1. Since it cannot be mass-produced at the production factory and must be produced according to the size of each order, it is very troublesome because the factory workers need to be prepared. 2. The assembled product is extremely heavy, and it is difficult and inconvenient to hang and carry with a crane. 3. For workers, the work efficiency is extremely low, and the labor cost is high and the cost is high. 4. It cannot be mass produced and exported.

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide the following things. In other words, the factory is equipped with standardized parts that can be installed quickly and easily to meet the demands of the construction site, thus reducing labor costs, lowering costs, and exporting. Can also be used as.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. In the telescopic door of the present invention, the frame and connecting plate for each part are made in advance at the production plant, and when they are transported to the construction site, the connecting plates are connected to each other according to actual demand to form the telescopic door. It can be molded. A pulley is provided at the bottom of the frame that is configured to run on rails, and the frame has vertical shaft holes, and the connecting plates are connected by the vertical shaft holes and can rotate in place. The projections are provided on both sides of the connecting plate, and the connecting plates adjacent to each other can be fitted to each other by the projections, and are connected so as to be freely rotatable by the connecting parts. It is a stretchable door.

In addition, the following can be performed. First. A groove is provided in the vertical axis of the connecting plate, and a fixed part is used for coupling with the bearing in this groove so that the bearing can be coupled with the shaft hole of the frame to rotate in a fixed position. Second. The frame and connecting plate should be able to be stored as individual parts. Third. A coil spring and an outer tube are fitted on the shaft of the connecting plate, and both ends of the coil spring are fixed to the connecting plate and the frame, respectively, and the connecting plate is driven from the spiral direction opposite to the spiral direction of the coil spring to set the predetermined direction. To be able to rotate to.

【Example】

 Examples will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention, which is composed of parts such as a frame 1 and a connecting plate 2. The frame 1 can be made in various shapes, and a pulley 11 is provided at the bottom of the frame 1 so that the frame 1 can run smoothly on the rails 10. A lower shaft hole 13 is provided. The upper shaft hole 12 and the lower shaft hole 13 are used for rotatably fitting the shaft 21 of the connecting plate 2, and the connecting plate 2 can be rotated at a fixed position by the upper shaft hole 12 and the lower shaft hole 13. It will be possible (see Figures 5 and 6). The connecting plate 2 is provided with an integrally formed upper shaft 21 and lower shaft 21, and grooves 22 are provided in the upper shaft 21 and the lower shaft 21. In the groove 22, a fixed component such as a C-shaped ring 23 Are mounted to secure the bearing 24. Therefore, the connecting plate 2 is supported by the upper shaft hole 12 and the lower shaft hole 13 of the frame 1 so that it can rotate in a fixed position.

Further, the protrusions 25 are provided on both sides of the connecting plate 2, and the adjacent connecting plates 2 can be fitted to each other by the protrusions 25, and can be freely rotated by a connecting component 26 such as a pin. Are combined as. Further, when the connecting plate 2 is contracted, the connecting plate 2 comes to be contracted in a fixed direction, so that the coil spring 27 and the outer pipe 28 are attached to the upper shaft or the lower shaft of the connecting plate 2. Both ends of the coil spring 27 are fixed to the connecting plate 2 and the frame 1, respectively, and the connecting plate 2 can be driven to rotate in a predetermined direction from the spiral direction opposite to the spiral direction of the coil spring 27. it can.

As shown in FIGS. 2 and 3, the present invention uses several frames 1 and a connecting plate 2 between them to connect them. Therefore, each frame 1 can run on the rail 10, and when several frames 1 are connected, they are formed into a door. Also, a frame can be used at the beginning or the end of this door to make it up at the starting side or the ending side. Further, if necessary, it can be connected to a power part and each frame can be pulled to run on the rails 10. Further, the connecting plate 2 can be rotated by the connecting part 26 in a certain direction. As they are collected, each frame 1 can shrink to a minimum thickness.

[0011]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. In the case of the present invention, if the frame 1 and the connecting plate 2 as the respective parts are made in advance at the production factory, these can be easily transported to the construction site and can be easily assembled by the worker. For this reason, the transportation cost and the assembly cost are extremely low as a whole, and the standardized products can be produced in large quantities in the production factory, so that the efficiency of the work is improved and the setup of the workers can be done well. Therefore, the production cost can be reduced.
