[0002]

2. Description of the Related Art A long hinge for a folding panel device of this kind is known from Japanese Patent Application Laid-Open No. 4-368585. In this known long hinge, a pedestal is fixed to an upper portion of an intermediate body having bearing portions on both sides in the width direction, and both side surfaces in the width direction of the pedestal are orthogonal to a first cam surface orthogonal to the hanger rail longitudinal direction. The surface on which the panel rotates is formed on each of the second cam surfaces parallel to the hanger rail, and the pivot is disposed on the horizontal frame of the panel so as to freely enter and exit the panel in the width direction of the panel. Form a sliding surface that slides on the cam surface of the pedestal, provide a spring that pushes the pivot between the horizontal frame and the pivot, and when the panel is extended,
The spring brings the sliding contact surface into close contact with the first cam surface so that all panels are aligned in the longitudinal direction of the hanger rail, and when the panel is folded, the spring brings the sliding contact surface into close contact with the second cam surface. Thereby, all the panels are aligned perpendicular to the hanger rail longitudinal direction.

[0003]

The known device has a problem that the structure of the panel is complicated because the pivot and the spring for pressing the pivot are disposed in the horizontal frame of the panel. Further, there is a problem that the operation of the entire panel device becomes unstable because the left and right panels sandwiching the hinge are independent and move separately.

The present invention has been made to solve this problem. It is an object of the present invention to stably align all the panels in the longitudinal direction of the hanger rail when the panel is extended, and to align the entire panel when the panel is folded. The present invention is to provide a long hinge capable of stably aligning the vertical direction of the hanger rail, and being independent from the side frame of the panel.

[0005]

In order to achieve the above object, means adopted by the present invention comprises first and second shafts formed integrally with panel joints on both sides of a long hinge. A cam having a cam surface is fixed, and a spring for compressing in the width direction is provided at the center of an intermediate body having a bearing portion for bearing both shaft portions. The first cam surface is perpendicular to the panel width direction,
The second cam surface is formed perpendicularly to the first cam surface on the panel rotation side. A panel is formed by linking, via a link, a position eccentric inward in the width direction from the center of one shaft of the cams on both sides provided on the long hinge and a position eccentric to the panel rotation side from the center of the other shaft. It is desirable to make it easy to fold.

[0006]

According to the operation of the panel, the cams at the upper ends of both shaft portions of the long hinge also rotate together. When the panel is fully deployed, the gap between the two cams is parallel to the first cam surface of both opposing cams, and when the panel is completely folded, the second cam surface of the two opposed cams is parallel to the other. Sometimes the first of both cams
The intersection of the cam surface and the second cam surface compresses the spring.
The compression of the spring is minimized when the panel is fully deployed and folded, where the first and second cam surfaces are parallel, and maximized when the panel rotates one quarter of the way in between. Therefore, when the panel is rotated by a quarter turn or more in order to unfold or fold the panel device, the compression springs disposed between the cams stably move all the panels straight or vertically in the longitudinal direction of the hanger rail. Align. Since the cam and spring for aligning the panel are provided on the long hinge, there is no need to change the structure of the panel with the cam and spring.
