  Further, the door opening / closing mechanism 3 is configured using a guide rail 32 that is movably engaged with the frame member 2 via a plurality of rollers 31 in the opening / closing direction, and the door body 4 is connected via the door opening / closing mechanism 3. Since the length of the door opening / closing mechanism 3 can be shortened, the door opening / closing mechanism 3 itself can be housed inside the door pocket 1, and the door pocket similar to a conventional movable home fence. The length of 1 can be shortened.

Next, improvement in the transportability of the door device according to Embodiment 1 will be described.
FIG. 5 is a perspective view showing an exploded example of the door device shown in FIG. 1 at the time of shipment. This movable home fence constitutes a portion of the door body 4 and the door opening / closing mechanism 3 excluding the guide roller 31, a base member 11 constituting the lower part of the door pocket 1, a frame member 2 provided with the guide roller 31, and an upper part of the door pocket 1 The door pocket frame 12 is transported in a state of being divided into a total of three members. In general, the weight of the movable platform fence is about 150 kg to 250 kg, and it requires special jigs and tools for transportation between the manufacturing / assembly factory and the platform where it is installed. Carrying in was difficult. This movable home fence is divided into three parts that can be carried by an operator in view of the above situation, thereby improving the transportability.

  Next, the manufacturing method of the said door body 4, the door opening / closing mechanism 3, the base part 11 of the door pocket 1, the frame member 2, and the door pocket frame 12 is demonstrated with reference to FIG. FIG. 6 is an assembly perspective view of the door body and the door opening / closing mechanism of the door device shown in FIG. First, the door body 4 and the door opening / closing mechanism 3 are manufactured. The plate-like body 41 and the plate-like body 42 constituting the door body 4 are manufactured by using, for example, an iron coated steel plate whose surface is previously coated and bending it into a desired shape. Next, the moving element 34 and the guide rail 32 use, for example, an iron-based material such as a steel material as a material, and are cut into a desired shape, for example. At this time, a shaft 33a for attaching the guide roller 33 is also formed at the same time. The shaft 33a may be formed integrally with the guide rail 32, or a hole may be formed in the guide rail 32, and a separately manufactured shaft may be inserted and fixed.

  Next, the guide roller 33 is manufactured. The peripheral part of the guide roller 33 is made of, for example, polyurethane, which is a thermoplastic resin, and a bearing is inserted in the central part. As a manufacturing method thereof, there is an insert molding in which a bearing is inserted into a mold dug into the shape of the guide roller 33, and polyurethane that has been heated and melted to a predetermined temperature is filled into the mold. The guide roller 33 thus manufactured is fitted into the shaft 33a. Next, the moving element 34 is fixed to the plate-like body 41 with bolts 72 (shown in FIG. 3). Then, the moving element 34 is passed between the upper and lower guide rollers 33. Finally, the plate-like body 42 is attached to the plate-like body 41 so that the door opening / closing mechanism 3 is housed inside the door body 4. In addition, when passing the moving element 34 between the guide rollers 33 opposed vertically, the guide roller 33 rotates and the guide roller has a circular shape, so that it can be easily inserted.

Next, the component which integrated the base part 11 and the frame member 2 of the door pocket 1 is manufactured.
First, for example, a steel material is used as the material of the frame member 2 and is cut into a desired shape, for example. At this time, the diameter of the hole 2 b through which the bolt 71 (shown in FIG. 3) passes when connecting to the pedestal portion 11 of the door pocket is larger than the outer diameter of the bolt 71 by a predetermined dimension. This is to adjust the orientation of the door body 4 at the time of installation as will be described in detail later, and the difference in diameter between the bolt 71 and the hole 2b is an adjustment allowance. Note that the shaft 31 a formed integrally with the frame member 2 to which the roller 31 is attached and the method for manufacturing the roller 31 are the same as the guide rail 32 and the guide roller 33 described above, and thus are omitted.

Next, the base part 11 of the door pocket 1 is manufactured. For example, a steel material is used as a material, and constituent parts are manufactured by cutting or the like and assembled using bolts 71. Finally, the pedestal 11 of the door pocket 1 and the frame member 2 are temporarily fixed with bolts 71.
Next, the door pocket frame 12 is manufactured. The components of the door pocket frame 12 are made of steel, for example, and are assembled with bolts after being processed by pressing or cutting. In addition, the motor 20, an electronic board (not shown), wiring, and the like are accommodated and fixed inside the door pocket frame 12.

  Next, the installation method of the movable home fence of this Embodiment 1 is demonstrated using FIG. 7A and 7B are diagrams for explaining the installation procedure of the movable platform fence. FIG. 7A shows the platform 11 and the frame member 2 installed on the platform. FIG. 7B shows the door frame 12 on the platform 11. (C) shows the assembly of the door body 4 and the door opening / closing mechanism 3, and (d) shows the assembly of the engagement holding means 6a and the drop-off prevention means 6b. First, the base 11 and the frame member 2 of the door pocket 1 are installed on a platform (not shown) as shown in FIG. At that time, a spacer (not shown) is sandwiched between the platform and the pedestal portion 11 of the door pocket 1 to level the pedestal portion 11.

  And as shown in FIG.7 (b), the door pocket frame 12 is connected with the base part 11 with a volt | bolt. After that, as shown in FIG. 7C, the guide rail 32 is inserted between the rollers 31 facing each other in the vertical direction while inserting the door body 4 incorporating the door opening / closing mechanism 3 from the door entrance 12a of the door pocket 1. To do. Next, as shown in FIG. 7 (d), the engagement holding means 6a and the drop prevention means 6b are attached. The engagement holding means 6a prevents the guide rail 32 and the frame member 2 from coming off, and the drop prevention means 6b prevents the moving element 34 and the guide rail 32 from coming off. In addition, when passing the guide rail 32 between the opposed rollers 31, the roller 31 rotates or the roller 31 has a circular shape, as in the manufacture of the door opening / closing mechanism 3, so that it can be easily inserted. I can do it.

  Next, the height and direction of the door body 4 are adjusted. In the case where the movable home fence is disposed oppositely, if the installation surface of the platform is curved, a gap is generated between the door bodies 4. However, since the movable home fence supports the door body 4 by the frame member 2, the displacement of the door body 4 can be easily corrected by adjusting the height and direction of the frame member 2. Specifically, the height of the door body 4 is adjusted by removing the bolt 71 temporarily fixing the pedestal 11 and the frame member 2 of the door pocket 1 and sandwiching a spacer between the pedestal 11 and the frame member 2. The direction of the frame member 2 can be adjusted by the dimensional difference between the hole 2b formed in the bent piece 2a of the frame member 2 and the fixing bolt 71, and the direction of the door body 4 can be easily adjusted. In this way, compared to the conventional movable home fence that is integrated and transported at the assembly plant because of high processing accuracy, and the inclination is adjusted by inserting a spacer between the platform and the movable platform fence. Therefore, this movable platform fence is excellent in installation.

  In the first embodiment, a steel material is used as a constituent material for the frame member 2 and the like. However, the present invention is not limited to this. For example, a metal material such as stainless steel having rust resistance is used, or the door body 4 or Lightweight aluminum, an alloy material thereof, a resin material, or the like may be used as a decorative plate of the door pocket 1. Moreover, although polyurethane which is a thermoplastic resin was used as the material of the guide roller 33 and the roller 31, it is not limited to this, and a different resin, metal, or the like may be used. In addition, four rollers and guide rollers are attached to the frame member 2 and the guide rail 32, respectively. However, the present invention is not limited to this. In addition, the movable home fence is divided and transported into three parts at the time of transportation.

  As described above, according to the first embodiment, when the door body 4 is opened, the upper part of the door opening / closing mechanism 3 and the frame member 2 is accommodated in the accommodating portion 40 at the lower part of the door body 4, so that the door pocket 1 It is not necessary to project the lower part of the door in the thickness direction of the door pocket, the design is improved, and the door pocket 1 and the door body 4 can be made thinner and lighter. Further, the door opening / closing mechanism 3 is engaged with the frame member 2 via a total of four rollers 31 installed in pairs so as to face up and down at two locations separated in the opening / closing direction. Since the load can be distributed to the plurality of rollers when a load is applied to the upper end of the door with the door body 1 closed, the durability is improved. Further, since the roller 31 is used, the assemblability is improved as compared with the linear guide, the required processing accuracy at the time of manufacturing the component can be lowered, and the workability and the installation property are improved. Moreover, transportability can also be improved.
