  Hereinafter, an embodiment of the folding enclosure fence of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a state in which a foldable enclosure fence 100 according to the present invention is used as an enclosure fence. The enclosure fence 100 is an enclosure fence in which four rectangular fences 1, 2, 3, and 4 are connected in a rectangular shape in plan view. Both of the fences 1 and 2 used for opposing short sides have a short side width. The two small fences (1a and 1b, 2a and 2b) are connected in a straight line. As with the large fence 3 shown as an example in FIG. 2, each of the six small fences (1a and 1b, 2a and 2b) and the two large fences 3 and 4 arranged on the long side are as follows. A rectangular frame is formed by connecting the cylindrical tube elbows 5 arranged at the four corners with a cylindrical tube 6 having an outer diameter equal to the inner diameter of the cylindrical tube elbow 5, and a net, cloth, wire mesh, etc. are stretched on the frame surface. It is configured.

  This enclosure fence 100 is a foldable type, and two hinges are attached between the frame bodies of the adjacent fences at the four corners of the rectangle in plan view so that the surface angle between the frame bodies can be opened and closed at least 0-90 degrees. It is. Two hinges that can open and close each other at an angle of 0 to 180 degrees are attached between the frames of adjacent small fences (1a and 1b, 2a and 2b). The short side width of the two adjacent small fences (1a and 1b, 2a and 2b) arranged on each short side is narrower than the frame width of the large fences 3 and 4 arranged on the long side. Therefore, the connecting portions of the adjacent small fences (1a and 1b, 2a and 2b) are bent toward the inside of the surrounding fence 100, and at the same time, the connecting portions of the adjacent fences at the four corners of the rectangle in plan view have a small surface angle. By folding in such a direction, each frame can be finally folded as shown in FIG.

  Next, the structure of the hinge attached between the frame bodies of the fences adjacent at the four corners of the rectangle in plan view will be described. The hinges attached to these four corners can open and close the surface angle between adjacent frames at least 0-90 degrees. The surface angle between the adjacent small fences (1a and 1b, 2a and 2b) is maintained at 180 degrees, that is, the surface angle between the frames is 90 degrees by the hinges at the four corners while keeping the plane open. Then, the enclosure fence 100 becomes a rectangular fence in plan view. When the opening angle of one of the two connecting portions located diagonally is greater than 90 degrees and the other is less than 90 degrees, the enclosure fence 100 becomes a parallelogram-shaped fence in plan view. In addition to the change in the opening angle, if the surface angles of the adjacent small fences (1a and 1b, 2a and 2b) are different from 180 degrees, the enclosure fence 100 has a complicated hexagonal shape in plan view. can do.

  However, when the enclosure fence 100 is installed around household waste or used to limit the range of movement of pets, it is preferably rectangular in plan view. For this purpose, it is necessary to attach hinges that do not make the inter-frame surface angle between adjacent fences greater than 90 degrees at the four corners of the rectangle in plan view. 4 and 5 are perspective views showing a state in which such a hinge 8 is attached, and is an upper corner portion of a connecting portion of the small fence 1 and the large fence 3 in FIG. 1, and FIG. The angle is 90 degrees, and FIG. 5 shows a state in which the angle between the adjacent frames is 0 degree.

  The hinge 8 is configured as an insertion / removal hinge with an opening / closing restriction, and is composed of first and second hinges 9, 10, a pin 11, and an opening / closing restriction component 12 as shown in an exploded perspective view of FIG. 6. The first and second hinges 9 and 10 have the same shape, and a pin insertion hole 13 through which a pin 11 serving as a turning center axis passes is provided in the base end portion so as to penetrate in the longitudinal direction of the hinge 8. At the distal ends of the first and second hinges 9 and 10, there is a cylindrical tube 14 whose inner diameter is equal to the outer diameter of the cylindrical tube 6 that connects the cylindrical tube elbows 5 and whose length is equal to the longitudinal length of the hinge. The center line is attached so that the extension line in the hinge width direction passes. The opening / closing restriction part 12 is a U-shaped part in which the both ends in the longitudinal direction of the rectangular plate are bent at right angles, and the inner width between the bent parts 12a and 12a is twice the length in the hinge longitudinal direction. A pin passage hole 12b through which the pin 11 passes is formed.

  When assembling these parts into the hinge 8, the first and second hinges 9, 10 are first connected in series with the pin insertion holes 13 as shown in FIG. The component 12 is arranged so that the pin passage hole 12b of each bent portion 12a is continuous with the pin insertion hole 13 of the hinge. In this state, the pin 11 is passed through the upper and lower pin passage holes 12b and the pin insertion holes 13 of the hinge, and the other end is projected to the lower side of the opening / closing restriction part 12. The protruding lower end tip is caulked so that the first and second hinges 9, 10 and the opening / closing limiting part 12 can rotate around the pin 11 to prevent the pin 11 from coming off.

  The first and second hinges 9 and 10 are rotatable within a range of 90 to 180 degrees between the opening and closing angles. FIG. 9 is a perspective view in a state where the opening / closing angle is 180 degrees, and FIG. 10 is a perspective view in a state where the opening / closing angle is 90 degrees. When the opening / closing angle is set to 180 degrees, the first and second hinges 9 and 10 are brought into contact with the inner surface of the opening / closing limiting component 12 so as not to open further. From the pin insertion holes 13 of the first and second hinges 9 and 10 so that the maximum opening and closing angle is limited to 180 degrees, the short side width of the opening and closing restriction component 12, the center position of the hole 12b of each bent portion 12a, and so on. The distance to each cylindrical tube 14 is adjusted. 11 is a cross-sectional view taken along the line AA in FIG. 4, and the opening and closing angles of the first and second hinges 9 and 10 are limited to 180 degrees, and FIG. 12 is taken along the line BB in FIG. A plan view of the first and second hinges 9 and 10 and the opening / closing limiting component 12 in a state where the opening and closing angle of the first and second hinges 9 and 10 is 90 degrees is shown in a sectional view.

  The hinge 8 is attached in a state where the cylindrical tube 6 of the frame is passed through each cylindrical tube 14 at the tip in the width direction of the first and second hinges 9 and 10. As shown in FIG. 2, the assembled frame cannot be attached later as is done with a normal insertion / extraction hinge. The hinge 8 must be attached during the assembly of each frame. There are several possible procedures, but the following is recommended. It demonstrates referring the connection part of the small fence 1a and the large fence 3 shown in FIG. The large fence 3 before being attached to the cylindrical pipe elbow 5 and the respective cylindrical pipes 6 on the small fence 1a side are passed through the cylindrical pipes 14 of the first and second hinges 9 and 10 of the hinge 8 before the pin 11 is inserted. . In this state, each cylindrical tube 6 on the frame side is inserted into each cylindrical tube elbow 5 to complete the small fence 1a and the large fence 3 separately. Next, the first and second hinges 9 and 10 attached to the small fence 1a and the large fence 3 are connected in series as shown in FIG. Next, as shown in FIG. 8, the opening / closing limiting component 12 is arranged so that the pin passage hole 12b of each bent portion 12a is connected to the pin insertion hole 13 of the hinge, and the pin 11 is attached and protrudes in that state. Crimp the tip of the bottom edge.

  In this state, the hinge 8 is movable in the vertical direction along the cylindrical tubes 6 of the small fence 1a and the large fence 3, and each cylindrical tube 6 is moved in the cylindrical tubes 14 of the first and second hinges 9 and 10. It is in a turnable state. In order to stop these movements and swiveling operations, a screw hole is formed in the side surface of each cylindrical tube 14 of the first and second hinges 9 and 10 toward the center of the cylindrical tube, and a screw 17 is screwed into the screw hole so as to be hinged. 8 is fixed to each cylindrical tube 6 of the small fence 1 a and the large fence 3. As shown in FIGS. 4 and 11, the first and second hinges 9 and 10 have an opening angle of 180 degrees, and in this state, the center of the two cylindrical tubes 14 of the first and second hinges 9 and 10 is fixed. Adjust the turning position of the small fence 1a and the large fence 3 so that the frame surface of the small fence 1a is perpendicular to the line connecting the lines, and the frame surface of the large fence 3 is the extension direction of the connecting line. A screw 17 is screwed into the screw hole to fix the hinge 8 to each cylindrical tube 6. If fixed in this way, when the small fence 1a is turned so that the opening angle of the small fence 1a and the large fence 3 is 0 degree, the state shown in FIGS. The small fence 1a and the large fence 3 can be folded up.

  Next, an example of a hinge structure of a portion connecting adjacent small fences will be described by taking an example of a portion connecting the small fence 1b and the small fence 1a in FIG. FIG. 13 is a perspective view of a state in which such a hinge is attached and connected, and FIG. 14 is a cross-sectional view taken along the line CC of FIG. This hinge 15 uses three parts of first and second hinges 9 and 10 and a pin 11 among the parts for the hinge 8 shown in FIG.
