Abstract

PROBLEM TO BE SOLVED: To make it possible to eliminate the need for the application of an exclusively designed stile since a folding door is arranged to be folded reversely prior to the formation of the sliding door which travels along a guide rail in a curved site. SOLUTION: There are formed a first rotary receiver 9b where an extension length A is set to a stile 9 of a panel body 2 and a second rotary receiver 9c where an extension length B shorter than the first rotary receiver 9b is set thereto. A connecting rail 3 between the first rotary receiver 9b and the second rotary receiver 9c are internally fitted in so that the rotary angle of the stile 9 to the connecting rail 3 may be set differentially. This construction makes it possible to connect the folding door in a reversed folding state and in a non-reversed folding state by changing the top and bottom of the stile 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical frame connecting structure for a folding door installed in a building such as a building or a house.

[0002]

2. Description of the Related Art Generally, a folding door is designed to be transformed into a storage posture in which a plurality of door bodies connected in series are folded in a zigzag shape and a closed posture in which they are spread in a line. ,
As a connecting structure therefor, there is a structure in which adjacent vertical frame members of adjacent doors are rotatably supported by the connecting frame. In this structure, the rotation angle of the connecting frame and the vertical frame is limited to an angle at which adjacent door members do not reversely bend, so that the transformation can be performed smoothly. By the way, today, with the diversification of architectural styles, it is attempted to guide a folding door to a guide rail with a curved part.In that case, the connecting frame and the vertical frame of the connecting part that bends toward the center of the curve during storage are It is necessary to rotate it to the reverse folded state at the time of extension. Therefore, if the guide rail has a curved portion, if all the guide rails can be rotated to the reverse bent state, the smoothness of the opening and closing operation will be impaired. The connection part that bends at a certain angle can be reverse-folded to a required angle, and the connection part that bends at the curved outer side does not reverse-bend, and the separately formed parts are connected to each other.

[0003]

Therefore, in the above-mentioned conventional one, the number of parts is large, and it is difficult to distinguish between those that are reverse-folded and those that are not reverse-folded.
It is often the case that the number of things that do not fold back is wrong and the number of things that do not fold back is complicated, and there is also the problem of complicated material management, and this is the problem to be solved by the present invention.

[0004]

The present invention has been made in view of the above circumstances in order to solve these problems, and a plurality of door bodies connected in series are zigzag-shaped. In a folding door that is transformed into a folded storage position and a closed position in which it extends in a row, the vertical rails of the adjacent doors that face each other are rotatably supported by connecting rails. In doing so, a rotation support shaft portion and a rotation restricting portion are formed on the connecting frame, while a pair of rotation receiving portions that rotate along the vertical frame are guided by the rotation supporting portion, and the rotation support portion. A pair of regulation receiving portions that abut on the motion regulating portion and regulate the rotation of the door bodies beyond the closing posture are formed. It is set so that it will come into contact with the rotation restricting part in the state where it does not fold backward, and the other one is the door body In the set of contacts the rotation restricting portion in the reverse folded condition, is obtained by replaceably configured to the specifications of broken reverse and specifications without reverse bending in vertical recombination stile. As a result, it is possible to selectively assemble one type of vertical frame into the reverse-folded state and the non-back-folded state. The number of parts can be reduced, the material management can be simplified, and the wrong ones will not be brought to the site.

[0005]

FIG. 1 shows an embodiment of the present invention.
8 shows, in the figure, 1 is a top-hanging folding door, and the folding door 1 includes a plurality of long plate-shaped panel bodies (door bodies) 2 and a connecting frame 3 to be described later. A suspension roller 4 is provided at every other connection frame 3, and the suspension roller 4 is provided on the guide rail (above the opening). The folding door 1 is moved to each panel body 2 by traveling on the suspension rail) 5.
Are in a closed posture in which they are extended in a line and close the opening, and each panel body 2 is transformed into an open posture in which it is folded in a zigzag shape at the door pocket 6 portion.

By the way, a curved corner portion R is formed on the guide rail 5 so that the folding door 1 is closed in a curved shape. The part that bends to the back is in a state where it can be reverse-folded, and the part that bends to the outside of the curve is connected so as not to be reverse-folded. Here, the panel body 2 is formed such that four circumferences thereof are surrounded by upper and lower frames 7, 8 and left and right vertical frames 9, respectively, and the vertical frames 9 of the adjacent panel bodies 2 are rotatably connected to each other via the connection frame 3. However, in the connection structure, it is set so that the adjacent panel members 2 can be selectively connected to each other in the state in which they are folded backward and the state in which they are not folded while using the same vertical frame 9.

That is, the connecting frame 3 is integrally formed of a metal mold material, and the connecting frame 3 has a frame main body 3a having a substantially rectangular cross section and one of the left and right side surfaces of the frame main body 3a in one of the indoor and outdoor directions. The connecting portion 3b extending toward the front and the rotation support shaft portion 3c formed in a substantially cylindrical shape at the tip of the connecting portion 3b are integrally formed. However, the connecting portion 3b projects in a substantially L shape. It extends so as to widen from the tip toward the tip side, and the turning support shaft portion 3c is formed at the tip thereof in a state of being separated from the frame body 3a. Further, a protrusion 3h projecting in a step shape is formed on the outer peripheral surface of the rotation support shaft portion 3c, and the frame main body 3a of the protrusion 3h is formed.
The side opposite to and the opposite side surface become the first and second restriction surface portions 3d and 3e, respectively, and the surface portions of the connecting portion 3b extending in an expanded manner are the third and fourth restriction surface portions 3f and 3g. It is set.

On the other hand, the vertical frame 9 is integrally formed of a metal mold material similarly to the connecting frame 3, but the vertical frame 9 has a groove-shaped mounting portion for fitting and supporting the side edge of the panel 2a. 9a and a pair of first and second rotation receiving portions 9b and 9c extending in opposite directions from both edges of the groove bottom portion of the mounting portion 9a are integrally formed. Then, these first and second rotation receiving portions 9b and 9c
As described later, the first rotation receiving portion 9b is set to be longer than the second rotation receiving portion 9c, and the rotation supporting shaft portion is provided between the rotation receiving portions 9b and 9c. 3c is loosely fitted inside. Further, the first and second rotation receiving portions 9
First and second bent portions 9d and 9e are formed at the tips of b and 9c so as to face each other, and the tips of the first and second bent portions 9d and 9e are formed as described above. It is set so that it can slide on the outer peripheral surface of the pivot support shaft portion 3c which is fitted therein, and thereby the adjacent panel bodies 2 can be folded and rotated.

Here, the selection between the state in which the adjacent panel bodies 2 are folded back and the state in which they are not folded back is selected by the following configuration. Here, as described above, the extension lengths A and B of the first and second rotation receiving portions 9b and 9c from the mounting portion 9a.
Is the length A of the first rotation receiving portion 9b is the second rotation receiving portion 9c.
Is set longer than the length B (A> B). When the panel body 2 is assembled, the vertical frame 9 is turned upside down and assembled, so that the long first rotation receiving portion 9b faces the frame body 3a when in the open position (folding position) (see FIG. 5). (State shown in FIG. 6) and a state in which the short second rotation receiving portion 9c faces the frame body 3a (state shown in FIG. 6) are selectively assembled. When these assembled parts are placed in the closed position (extended position), in the former one, the first bent portion 9d abuts on the first restriction surface portion 3d, and the second bent portion 9e moves to the fourth position. In the latter, the second bent portion 9e contacts the first restricting surface portion 3d, and the first bent portion 9d is the first bent portion 9d. (4) It abuts against the restriction surface portion 3g, and further rotation is restricted. In this case, since the first rotation receiving portion 9b is longer than the second rotation receiving portion 9c (A> B), the former rotates at a larger rotation angle, and the rotation angle The former one, which has a larger rotation angle, is in the reverse folding state beyond the linear extension state, and the latter one, which has a smaller turning angle, is set to prevent the reverse folding up to the linear extension state. Then, the former connecting structure is adopted as the connecting structure of the part that is folded inside the curve, and the latter connecting structure is set as the connecting structure of the part that is folded outside the curve. Here, in the present embodiment, the door pocket 6
Is arranged on the curved outer side, and as a result,
The connection between the vertical frame 9 and the connection frame 3 at the portion where the hanging roller 4 is provided is bent inward, and the connection structure in the state of being reversely folded is adopted. In addition, 10
Is a swing-off roller provided at the lower end of the connecting frame 3 on which the hanging roller 4 is provided. A frame, 13 is a door-end side vertical frame, and 14 is a door-end side vertical frame.

In the embodiment of the present invention constructed as described above, the folding door 1 has a structure in which, among the connections of the adjacent panel bodies 2, the connection of the portion that is folded inside the curve exceeds the linear state and is reversely folded. Because it is configured to spread to the state,
An opening / closing operation for smoothly moving the curved corner portion R will be performed, but in this thing, by vertically changing one type of vertical frame 9 and incorporating it in the connecting frame 3, it can be extended only to a linear state. It is possible to select the connection of 6 and the connection of FIG. 5 which extends beyond the straight state to the reverse folded state.

That is, when the panel body 2 is rotated in the extended posture, the rotation receiving portions 9b and 9c are the first and fourth regulating surface portions 3.
The first rotation receiving portion 9b comes into contact with d and 3g.
Since it is longer than the second rotation receiving portion 9c, by assembling the vertical frame 9 by turning it upside down (reversing), the rotation angle is different from that of whether it is bent backward or not. can do. As a result, one type of vertical frame 9 can be used for the one for reverse bending and the one for non-reverse bending, and there is no need to prepare a dedicated vertical frame for each member as in the conventional case. It can be used for multiple purposes, the number of parts is reduced, the material management is simplified, and there is no need to bring the wrong one to the site.

In carrying out the present invention, the door pocket may be provided in the direction of the center of the curve, and in this case, the present invention is adopted in a connecting structure with a connecting frame in which a hanging roller is not provided. Of course, and moreover,
It goes without saying that it is not necessary to adopt the reverse-folded connection for the connection of the portion of the panel body that does not reach the curved corner portion from the door-end side vertical frame in the closed posture. Further, various curvatures of the curved corner portion can be adopted, and it is needless to say that the lengths of the first and second rotation receiving portions can be set in accordance with this, and as a form having the curved corner portion, Although there are the ones shown in FIGS. 8 (X), (Y), and (Z),
For the case where there is a curved corner portion in the opposite direction as in the case of FIG. 8 (X), it can be dealt with by assembling so that the reverse folding directions are alternately reversed.
