The two connecting pieces 1 and 5 of the embodiment are approximately half the length of the fixing pieces 3 and 4, and are arranged vertically between the fixing pieces 3 and 4 when folded and closed. Through holes 6 are formed in the connecting pieces 1 and 5. The through hole 6 includes the fixed pieces 3 and 4 on the movable component side 7 (for example, a door) and the fixed frame side 8.
In accordance with (there may be another movable part), when it is attached to the screw hole 2 with a screw, since it is in the state of FIG. 2, the attaching work can be easily screwed from the front.

The connecting pieces 1 and 5 are provided with hinge mechanisms (hinge) on both sides thereof to rotatably connect the fixed pieces 3 and 4, but the support shaft 10 of the hinge mechanism of the connecting piece 1 is formed to be a little longer. Then, a cutout 12 is formed in the pipe portion 11 of the hinge mechanism of the connecting piece 5, and the pipe portion 11 is passed through the cutout 12 at a position where two hinge mechanisms of the hinge mechanism are linearly located. The projecting portion 13 of the support shaft 10 is inserted into the support shaft 10, and is engaged with each other at that position.

The operation of the metal fitting of this embodiment has a structure in which the fulcrum of rotation is provided on the left and right sides and can be opened from either the left or right side. To assemble the disassembling metal fitting of FIG. 1, fold the fixing piece 3 inside out as shown by the arrow, fold the connecting piece 5 to the front,
Insert the spindle 10 and assemble. FIG. 3 is a plan view of the left and right opening / closing fittings in a left opened state, FIG. 4 is a plan view in a closed state, and FIG.

In this configuration, the place serving as the rotation fulcrum is that when the upper and lower hinge mechanisms are located linearly as described above, the lower pipe portion 1
Since the projecting portion 13 of the upper support shaft 10 is inserted in 1, the weight of the movable component side 7 is evenly applied to the metal fittings, and the weight can be received as a whole, and a single linear long hinge mechanism is provided for rotation. The smoothness can be maintained.

FIGS. 6, 7, 10, and 11 are left and right opening / closing fittings based on the same principle as that of the above-mentioned embodiment, in which the connecting piece is formed in a long arm shape and the movable parts 7 are provided on both sides of the arm. The bent portion 15 corresponding to the thickness of the (door) is provided, the through hole 6 is opened, and the door 7 is attached to the left and right open / close doors 7. The left and right opening / closing fittings are fittings in which the fixing pieces 3 and 4 are rotatably connected to both ends of the first elongated connecting piece 1 having the through holes 6 in the both-side bending portions 15 and the both-side bending portions 15 through. The second long connecting piece 5 having the hole 6 is composed of a pair of metal fittings rotatably connected to both ends of the second long connecting piece 5 by a hinge mechanism. The movable component 7 side and the fixed frame 8 side are alternately attached and assembled. In FIG. 6, the pair of metal fittings are mounted above and below the movable part (single door) 7, respectively. Since only the fixed pieces 3 and 4 of the long connecting pieces 1 and 5 support the total weight of the movable part (single door) 7, the bottom of the movable part (single door) 7 can be reduced in order to reduce the load. Alternatively, it is preferable that the frame 16 of the fixed frame 8 is provided with a ball 16 urged in the protruding direction so that the ball 16 supports the weight at least when the door is closed so that the left and right opening / closing fittings are not weighted.

The embodiment shown in FIGS. 8, 9 and 10 is a partial cross-sectional view showing a movable part (lid) 7 of a floor-standing type container, in which a pair of metal fittings are attached to the movable part (lid) 7. It is installed on both sides of the tongue and is configured as a left and right pulling open / close lid. In FIG. 8, the connecting piece 1 is flat, and the fixing pieces 3 and 4 are attached to the side edges of the container in accordance with the relationship between the lid and the container. You can also FIG. 9 is a partially omitted perspective view of the metal fitting of FIG. 8 configured by a flat plate-shaped connecting piece.

In the left and right metal fittings shown in FIG. 12, the connecting pieces 1 and 3 are modified examples of long arm-like connecting pieces.
A piano wire 17 is stretched in the middle of each of the connecting pieces 1 and 5 corresponding to the arm portion. It can be applied to a relatively small movable part 7 and a lightweight part.

FIG. 13 shows a left and right opening / closing fitting having the long connecting pieces 1 and 5 provided with a structure in which two hinge mechanisms of the hinge mechanism are engaged with each other at a linear position. Support shaft 10 of hinge mechanism of one connecting piece 5
Is provided with a protruding portion 13 having a large diameter at the end portion 18 thereof, and the pipe portion 11 of the hinge mechanism of the one connecting piece 1 is extended, and a notch 12 having a locking step portion 19 therein is formed in this extension portion. Then, when the two hinge mechanisms come to a linear position, the spindle 1
The end portion 18 having a large diameter of 0 is fitted into the notch 12 having a corresponding shape, and is hooked on the locking step portion 19. When the two hinge mechanisms are separated from the linear position, the protrusion 13 comes out of the notch 12 and disengages.
Although the protruding portion 13 is provided on the lower connecting piece 5 in FIG. 13, the protruding portion 13 may be provided on the upper connecting piece 1 and the notch 12 may be provided on the connecting piece 5 in an opposite configuration. By providing the pipe 11 with the extension and the projection 13 on one side, a small gap can be formed between the connecting pieces 1 and 5 arranged in parallel vertically. As a result, unexpected friction between the connecting pieces 1 and 5 does not occur. Further, due to this engagement structure, the weight of the movable part 7 is evenly applied to the two hinge mechanisms, and the durability of the fixed pieces 3 and 4 is increased. Further, since the support shaft 10 of the hinge mechanism is engaged with the pipe portion 11 of another hinge mechanism, the linear state is maintained, and the smoothness of rotation is improved.

The above is one embodiment, and the left and right opening / closing fittings of the present invention are not limited to this. The change of material such as metal or synthetic resin, and the hinge mechanism is not limited to the hinge structure, and for example, a flexible tape joining may be used instead.
