DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage device for a horizontally extending folding door installed at an opening of a building, and more particularly to folding of a door panel when a closed folding door is folded in the width direction of the opening. The present invention relates to a storage device for a horizontally-folding folding door capable of performing a moving operation smoothly and reliably.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 12, a horizontally extending folding door is provided with a joint member c having a pair of pivot shafts b, b between adjacent frames a ', a' of adjacent door panels a, a. And the adjacent door panels a, a are respectively bent so as to be able to bend and stretch freely about the pivots b, b as a center of rotation.
The force in the direction of arrow A is inadvertently applied to the door panels a and a by the rotation restricting portions d and d for preventing reverse folding provided between the joint member c and the door panels a and a, respectively. In such a case, the one-sided closed state is maintained.

However, in the above-mentioned conventional configuration,
Since the rotation restricting portions d and the contact portion d 'of the d are located on the extension of each axis b' of the pair of pivot shafts b,
When the opening operation in the direction of arrow B is performed when the folding door in the closed state is opened, the operation force P1 in the opening direction applied to the axis b ′ of the pair of pivot shafts b abuts on each axis b ′. Since the acting force in the folding direction is not generated in a balanced manner at the portion d ′, the arrow B
Without simultaneously applying the operation force P2 in the folding direction other than the operation force in the direction, the folding door cannot be opened. Therefore, conventionally, in order to enable the opening to be opened only by the operation force in the opening direction, It becomes necessary to add an ammunition for urging in the folding direction, an auxiliary mechanism for folding, etc., which not only complicates the structure of the folding door, but also applies a large amount of operating force to the joint member when the door is opened. This has the disadvantage that the durability of the joint member is also reduced.

[0004]

SUMMARY OF THE INVENTION In view of the above situation, the present invention has been made to solve the conventional drawbacks, and an object of the present invention is to connect a closed folding door to a joint. Folds smoothly and lightly with a very simple structure and a small operation force without applying a great load to the members,
It is an object of the present invention to provide a storage device for a horizontally extending folding door that can be opened.

[0005]

Means for Solving the Problems In order to solve the problems, the technical means adopted by the present invention is to interpose a joint member having a pair of pivot shafts spaced apart and suspended between adjacent door panels, and In a horizontally-folded folding door in which a plurality of door supports are integrally formed on the vertical frame of the door panel and are engaged with the above-mentioned pivot shafts to connect a plurality of door panels in the opening width direction, the door panel is folded in the reverse direction.
Located on each side of the door panel to prevent folding
Formed on the side of the vertical frame via a rising surface with a fixed inclination angle
A rotation restricting part consisting of a stepped part is provided, and on the joint member side
Includes a contact surface of the arcuate contact point to said start up surface, the rising
On the inclined surface with an inclination angle smaller than the inclination angle of the surface
By providing a rotation restricting portion having a tip portion, each of the above-described rotation restricting portions is provided.
The contact position of the portion is deviated toward the door panel from the center of rotation of the pivot shaft, and an inverted C-shaped support portion is formed at both ends of the joint member facing the rotation restricting portion, The pivot shafts are integrally formed at their respective ends , and when the laterally-folding folding door is opened, the arc-shaped abutting surface on the joint member side and the vertical frame side are opened.
The rising position of each of the rotation restricting portions in a state of being in contact with the rising surface is a fulcrum when the folding door is opened.

[0006]

Therefore, according to the present invention, the closed folding door can be smoothly and lightly folded with a small operating force without applying a large load to the joint member.
The durability of the folding door can be improved.
