Description

[Detailed description of the invention] The present invention provides bearings 2, 2 on opposite ends of a pair of panels 1, 1 on the same side of the front and back, and protrudes on both sides of the connecting piece 3. The bearings 2, 2 are rotatably fitted to the shaft portion 4゜4, and both panels 1, 1 are foldably hinged. This invention relates to a hinge opening/closing device for a folding door, which is constructed by attaching finger-jam prevention backings 5, 5 to the sides and allowing the finger-jam prevention backings 5, 5 to freely come into contact with and separate from each other by folding and extending both panels 1, 1. The objective is to provide a safe hinge opening/closing device that prevents the risk of fingers being caught during folding.

The present invention will be explained in detail below with reference to the accompanying drawings.

Two or more panels 1 are foldably connected, and bearings 2, 2 are provided facing each other at appropriate positions or over the entire length of opposing ends of a pair of panels 1, 1.

These bearings 2, 2 are attached to the ends of the panels 1, 1 using mounting pieces 6, 6, and are arranged slightly biased to the same side on the front or back side of the panels 1, 1 as shown in Figure 1. has been done.

Further, the connecting piece 3 is provided with a shaft portion 4°4 on both side edges at a position offset to one side corresponding to the bearing 2.2 from the center of the thickness of the panels 1, 1. In the case of the figure, the bearings 2, 2 of the mounting piece 6 are
Finger jam prevention backing 5 that can be elastically attached to each other on the opposite side
, 5 are arranged.

This backing 5 is made of rubber, soft plastic, foam, or the like.

In addition, when there are three or more panels 1, as shown in Fig. 1, the connection parts between the bearings 2, 2 and the shaft parts 4, 4 are arranged alternately in the front side and the back side. It can be extended as a flat wall-like partition plate, or folded and opened.

In addition, in FIG. 1, 7 and 8 are lead panels.

In the present invention, as described above, bearings are provided at opposing ends of a pair of panels, biased toward one side of the front and back on the same side, and these bearings are rotated around shafts protruding from both sides of the connecting piece. Since they are movably fitted, the panel can be extended or folded into a flat wall by rotating the panel around the joint between the shaft and the bearing. Since it is offset to one side from the center, the opening and closing of the folding can be done smoothly with a small amount of force.Moreover, if left as is, a narrow space will be created on the opposite side of the joint when the panel is closed, making it difficult to open and close the panel. It is easy for fingers to get stuck in this empty space, but in the present invention, a backing to prevent fingers from getting caught is attached to the other side of the bearing at the end of the panel. The finger jam prevention gasket faces the gap between the ends of the panel, so it is safe even if your finger gets caught in the gap, and it is safe to use because your finger is unlikely to get caught. In addition, a finger-preventing backing is attached to the other side of the bearing at the end of each panel, so that the finger-preventing backings can freely come into contact with and separate from each other when both panels are folded and extended. Even if a finger is inserted between the panels, the finger will be pinched between the finger jam prevention banks, and the finger will not be pressed against any hard part, completely preventing injury due to finger jam. In addition, the finger jamming prevention backings come into close contact with each other with good airtightness, and there is an advantage that airtightness can be maintained at the hinged portion of the panel.
