DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a folding door in which two door bodies are foldably connected to each other so that the base end of the folding door is pivotally connected to one side of an opening. The present invention relates to a folding door device pivotally attached to a movable body movably engaged with a guide rail disposed inside a folding door in a deployed posture for closing the opening.

[0002]

2. Description of the Related Art A folding door apparatus of this type is different from a folding door apparatus of a type in which a vertical axis roller supported vertically above and below a free end of a folding door is directly guided by a guide rail. It can be arranged also on the lower side of the intermediate shelf plate in the opening, etc., and can be configured to cover the upper and lower sides of the folding door in the deployed position on the outside of the sill and duck section of the opening. Although having an advantage, the guide rail in the conventional folding door device of this type is disposed in parallel with the folding door in the deployed posture that closes the opening, and the distance between the guide rail and the folding door. Has been configured to be constant between both ends of the guide rail.

In this type of folding door apparatus, however, a folding door in a folding position for fully opening the opening and a folding door in an intermediate position from this folding position to a deployed position for fully closing the opening are provided. It was configured such that it was always an isosceles triangle with the guide rail as the base in plan view.

In other words, this type of folding door device includes a pivoting means for pivoting a base end of the folding door to one side of the opening and a free end of the folding door to the guide rail. It is necessary to use a pivoting means pivotally attached to a movable body which is movably engaged. Conventionally, however, the pivoting movement of the pivoting means of the folding door base end side from the pivoting center of the intermediate folding portion of the folding door is required. In order to make the distance to the center equal to the distance from the swing center of the middle folding part of the folding door to the swing center of the folding door free end side pivoting means, the same type of pivoting means is used for the folding door. It was necessary to attach it to both ends symmetrical position.

[0005]

However, this is not a folding door device of the type in which the entire folding door moves laterally along the guide rail, but the base end of the folding door is supported on one side of the opening as described above. In the case of a folding door device of the type described above, because of the relationship with the design when the folding door is closed and the frontage of the opening when the folding door is opened, the front end of the folding door is As a means, it is required that a wide variety of hinges be available, from single axis flat hinges to linked hinges (commonly referred to in the market as sliding hinges). On the other hand, the folding door play end side pivoting means is provided to prevent the pivoting means from being seen from the outside when the folding door is in the deployed position in which the opening is closed, or a side plate or an intermediate partition plate constituting the opening. In order to cover the free end of the folding door on the outside, it is required to use a uniaxial flat hinge type having a vertical support shaft adjacent to the back of the door body inside the free end inside corner of the folding door. Often done.

However, as described above, in the conventional folding door device in which the guide rails are arranged in parallel with the folding door in the deployed posture for closing the opening, the types of the pivoting means at both ends of the folding door are different, and the folding door is in the middle. If the distance from the center of swing of the bent part to the center of swing of the pivoting means at both ends of the folding door is not the same, one of the folding posture and the unfolding posture of the folding door is determined by the position of one end of the guide rail. Although it is possible to assume the expected posture by other postures, for example, the free end of the folding door in the unfolding position is separated from the opening forward and a gap is opened, for example, the folding door in the folding position, Inconveniences such as a posture that is greatly inclined inward from a normal posture protruding forward from the opening at a right angle to the right will occur.

In other words, in this type of conventional folding door device, it is not possible to freely select and use various types of hinges from the various types of hinges in response to markets and designers' requests as the folding door proximal end pivoting means. , There was a fatal flaw.
