Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an opening/closing device for fittings that normally does not open a hinged door beyond a certain level, but opens it wide when necessary.

[Conventional technology]

In general, when the windows of high-rise buildings are made into sliding doors, they open wider than necessary, which can cause not only objects but also people to fall into them. Therefore, hinged doors that do not open beyond a certain level are used.

[The problem that the idea aims to solve]

Traditional hinged doors that cannot be opened beyond a certain level cannot be opened wide for cleaning or repairs, etc.
The problem was that these tasks were extremely difficult to perform.

This invention normally restricts the degree of opening to prevent unexpected accidents and sudden jumps, and also provides a hinged door that can be opened sufficiently in special cases such as cleaning or repair, making it easier to work. The purpose is to obtain.

[Means to solve the problem]

This idea was created with these points in mind.
In a door whose rollers slide on a rail to open and close, two stoppers are provided on the rail to restrict the movement of the rollers, one stopper is fixed at all times and the other is detachable. It is something. More specifically, the window frame and
The upper and lower frames of this window frame and the upper and lower stile of each opposing hinged door are rotatably connected by arms,
A pivot bearing is attached to one end of each of the upper stile and the lower stile so as to be located on the same perpendicular line to each other, and a pivot shaft fitted to the pivot bearing of one of the stile and a pivot shaft fitted to the pivot bearing are installed on the window frame. a guide engagement piece having a U-shaped groove that slidably engages with the guide protrusion; a pivot shaft that fits into the pivot bearing of the other stile; A roller that slidably engages with a rail provided on the window frame is attached, and a fixed stopper is provided on the rail at a position remote from the pivot axis, and a fixed stopper is provided on the rail at a position that is closer to the pivot axis than the fixed stopper. A removable stopper is provided on a nearby rail.

[Effect]

Normally, the stopper on the removable side is engaged with the stopper on the fixed side. Then, the roller comes into contact with the stopper on the attachment/detachment side and restricts the hinged door from opening to a certain level. When the stopper on the removable side is removed from the rail as necessary, the roller slides until it comes into contact with the stopper on the fixed side, and the hinged door opens wide.
