Here, the cutout width of this guide rail is not only the total folding thickness of the panel, but in addition to the above, in addition to the above, in order to extend the panel and introduce it into the guide rail when closed. Width is needed.

[Problems to be Solved by the Invention] However, when the guide rail is widely cut out in this way, at least two panels on the suspension side are not held by the guide rail even in the closed state, and thus it is easy to cause fluttering due to wind pressure. .

The present invention has been made in view of the above problems, and an object of the present invention is to provide a swinging device for a folding door that can effectively prevent flaps of the panel located in the door pocket portion.

[Means for Solving the Problems] The present invention has been completed in accordance with the above object, that is, the present invention is characterized in that the side pieces of the guide rails in the door pocket portion are widened to a width of two panels or more. An opening frame having a first cutout opening and a second cutout opening formed by cutting the edge portion of the first cutout opening to a width narrower than that; and an edge within the cutout height of the first cutout opening. With the respective panels on which the doors are positioned; the two cutouts formed by projecting from the two end panels of the door pocket side end rotatably connected to each other through the connecting frame and the connecting frame. An oscillating device for a folding door, characterized in that it comprises an oscillating member extending within a height; and an oscillating base frame which is rotatably connected to a panel at an end of a door pocket side and is movable in an opening / closing direction. It is related to and is the gist.

[Operation] Each panel is opened by guiding an edge or a swinging member such as a guide roller provided at the edge to the guide rail of the opening frame. When it reaches the door pocket part, it is folded with the edge of the first cutout opening in order.

On the other hand, the closing is reversed, and the edge of the panel is inserted and guided in the guide rail of the opening frame, but the two panels from the edge of the door pocket side are within the range of the first cutout opening even when closed. However, its edge is not retained in the guide rail. However, a swing stop projectingly provided on either of these two panels or a connecting frame between them is inserted into the second cutout opening together with the closing rotation of the panel, and further moved in the opening / closing direction together with the suspension frame of the panel. Then, the swing stop is displaced from the second cutout opening and is housed in the guide rail.

[Embodiment] The present invention will be further described below with reference to the drawings showing an embodiment. Reference numeral 1 is a folding door, and the folding door 1 includes an opening frame 2

On the other hand, each U-shaped glass holding groove composed of a pair of side walls 12 and 12 is provided on each back side thereof. However, one of the swing frames 9 of the panel 4a at the end of the door pocket is rotatably connected to the joint hinge 8 of the suspension frame 7. Further, the thick fin-shaped kick-out portion 13 made of synthetic resin is screwed to the upper end of the vertical frame (or the upper frame) which is the upper part of the panel 4a at the end of the door pocket side, and is connected to the suspension frame 7. It is provided so as to project to the opposite side of the rotating shaft 14 of the rotating frame.

The panels connected in this manner are suspended and supported on the upper frame by the supporting door rollers 15 fixed above the respective first connecting frames 5 via the rotary shafts, while the horizontal door rollers 16 fixed on the respective lower portions are engaged with the lower frame. The first connecting frame 5 is always positioned in the plane of the opening frame, and is opened and closed during this period. The suspension base frame 7 is also movably supported on the upper frame 17 by a supporting door roller 15 which is fixed above the rotating shaft.

Further, a horizontal door roller 16 is provided above each second connecting frame 6, and a swing stop 18 is provided below the second connecting frame 6. When the folding door 1 is closed, the horizontal door roller 16 engages with the upper frame 17 and is shaken after the closing. The stop 18 is adapted to engage the lower frame 19. However, a swing stop 20 is provided above the panel 4a at the door pocket side end and the second connecting frame 6 between the adjacent panels so as to project relatively long upward.

The opening frame 2 is made of the same aluminum alloy extruded material, is provided with the upper frame 17, the lower frame 19, and the left and right end frames 21, 21 and is framed in a horizontally long rectangular shape, and the door pocket portion 22 is provided on one end frame side. It is provided as a preparation.

Then, the upper frame 17 is spaced apart from the upper frame 17 over the entire length in the longitudinal direction of the frame 2.
A guide rail 24 having a slightly elongated groove is provided below the travel rail 23 so that the above-mentioned support door car 15 can be supported and traveled. The rail 24 allows the horizontal door carriage 16 of each second connecting frame 6 to travel, and the door pocket 22 has
The rear side of the guide rail 24 is cut off over a total length 1 of the folding allowance 1 of the folding door 1 and the width l2 of two panels to provide a first cutout opening 25 for panel escape. is there. Further, the upper edge portion of the first cutout opening 25 is cut out to have a smaller width than this, and a second cutout opening 26 is provided. The width of the second cutout opening 26 is 120 mm to 130 mm in this example.

Here, the upper ends of the panels 4 and the horizontal door pulley 16 above the second connecting frame 6 are located within the cut-out height of the first cutout opening 25, while the panel on the door pocket side end is provided. A swing stop 20 projecting from the upper end of 4a is provided within the height of the second cutout opening 26.

On the other hand, the lower frame 19 includes an outer fixed frame 27 and an inner U-shaped movable frame 28 having substantially the same length as that of the outer fixed frame 27. A groove-shaped lower guide rail 29 is provided in the movable frame 28, and Horizontal door roller with 1 connecting frame 5
On the other hand, by making the movable frame 28 slantingly projecting and retracting relative to the fixed frame 27 while allowing the 16 to run, the swing stop is movable in the form of a fitting in the lower guide rail 29 when the folding door 1 is closed. The rear fin 30 of the frame 28 is inserted into the receiving groove 31 provided in the swing stop 18 to hold the folding door 1.

The projecting and retracting means 32 of the movable frame 28 is provided with a plurality of small door wheels 33, 33 at a plurality of positions in the left-right direction of the movable frame 28.
When the folding door 1 presses the engaging shaft 34 that is installed in the lower guide rail 29 of the movable frame in a blocking manner on the door pocket side or the door contact side, the small door wheels 33, 33 are moved to the opposite side of the blocks 35, 35. The movable frame 28 is configured to incline and project by being guided by the character-shaped inclination guides 36, 36.

By the way, in the door pocket portion 22 in which the upper frame 17 is provided with the first cutout port 25, the fixing panel 37 fixed in a fit-and-kill form in this example over the portion corresponding to the folding margin 1.
Is provided.

This fixed panel 37 is designed to hold the glass 3 in a frame 38 of four laps, so that the glass 3 is held from the center of the upper and lower frames 17 and 19 and the end frames 21 and 21 so as not to be caught in the opening / closing surface of the folding door 1. Also, while being displaced to the front side and fixed to these with screws, a cutout 40 is provided in the upper frame 39 of this fixing panel 37, and the cutout end is the end frame 21 on the door pocket side from the suspension base. A kick-out portion provided at a fixed position separated by the movement width of the frame 7 so as to project from the panel 4a at the end portion on the door pocket side.
A block-shaped contact part 41 made of a synthetic resin is provided with a screw so as to be able to face 13 freely.

By the way, to explain the open / closed state of the folding door 1,
When the folding door 1 folded in the door pocket 22 is pulled laterally to extend each panel 4 in order, the horizontal door carriage 16 provided above the upper end of each panel 4 and the second connecting frame 6 is an upper frame. From the end of the first cutout port 25 of 17 is introduced into the guide rail 24 in order. Reference numeral 42 in the drawing denotes a guide roller for introducing the upper end of the panel, which is provided at the end of the first cutout port 25. And
Finally, the panel 4a at the end on the door pocket side leans against the abutting portion 41 installed at a fixed position while the hanging base frame 7 is connected, and the kicking portion is brought into contact.

When this is pulled further sideways, the abutting part 41 is the panel at the end of the door pocket side.
4a is pushed to the opposite side of the rotating shaft 14, and the kicking portion 13 is pressed to apply a moment in the closing direction around the rotating shaft 14 to the panel 4a at the end of the door pocket to forcibly rotate it at a fixed position. The swing stop, which is moved and is caused to project to the upper end of the panel 4a at the end portion on the door pocket side by this rotation, is inserted into the second cutout opening 26 of the upper frame 17. Reference numeral 43 in the drawing denotes a synthetic resin guide piece provided at the swing-in / out port 26 for introducing the swing-off.

When the panel 4a at the end portion on the door pocket side is rotated to the closing angle along the opening / closing direction, the kick-out portion 13 projecting to the opposite side of the rotating shaft 14 is also parallel to the opening / closing direction and is attached to the contact portion 41. Remove the contact of.

When this contact is released, the panel 4a at the end of the door pocket is
And the suspension base frame 7 that connects the two are connected between the left and right end frames 2 of the opening frame 2.
Clearance between the inner width of 1,21 and the total panel width,
Alternatively, by using the movable width of the suspension base frame 7 to move the panel 4a at the end of the door pocket together with the suspension base frame 7 in the closing direction, the relatively long length of the panel 4a inserted into the second cutout opening 26 can be obtained. The swing stop 20 is displaced from the entrance / exit and fits into the upper frame 17.

Also, of course, below the folding door 1, the movable frame with the lower frame 19 protruding.
Hold it all the way to 28.

On the other hand, the opening of the folding door 1 is reversed to release the downward holding by the movable frame 28, and then the panel 4a at the end portion on the door pocket side and the second panel 4 adjacent thereto are shaken on the panel 4a at the end portion. The stopper is detached from the second cutout opening 26 along the guide piece 44 for guiding and folded, and in the following order, the upper ends of the panels 4 and the second connecting frame 6 and the horizontal door roller 16 above are firstly arranged. The folding door 1 is folded by separating it from the cutout opening 25. In this folding operation, the guide portion 44 guides the panel 4a at the end portion of the door pocket, and the impact portion 41 does not hinder the rotation of the kicking portion 13 of the panel 4a at the end portion of the door pocket. Absent.

In addition, the minimum cutout width of the first cutout opening is that the minimum panel width is two in order to introduce the panels from the first cutout opening into the opening frame while sequentially extending the panel from the door stop side when closing. It is usually said that the folding allowance of the folding door is added to this. The folding allowance may include the width of the hanging base frame or the door stop frame or may be designed excluding the width.

On the other hand, the removal width of the second removal port is only required to be smaller than that of the first removal port, since it is sufficient if the swing stop can be smoothly introduced and led out.

Although not shown, the swing stop to be inserted into the second cutout port is not limited to the panel on the door pocket side end portion, and may be projected on the second panel adjacent thereto or the connecting frame between them. ,
The second cutout port can also be opened at a position corresponding to this.

Further, the kicking-out portion may be formed by integrally forming a fin of the same quality on, for example, the swinging frame or the upper frame of the panel at the end portion on the door pocket side.
In the case of integrally molding on the turning frame, one of the side walls having the U-shaped glass holding groove may be integrally projected to the opposite side of the turning shaft. For example, to adjust the appearance, turn the side wall. It is also possible to form the entire length of the frame in the vertical direction, or to cut off the other part leaving only the part facing the abutting part. Further, when integrally molding the upper frame, the side wall end portion may be extended.

On the other hand, the abutting portion is the fixed panel of the illustrated example, or a sliding door or a folding door that is slid on the front side for opening and closing when the folding door is closed instead of the sliding panel, for example, a frame fixed by a lock. In addition to the above, the pole may be provided, for example, in a fixed position without providing such a partition.

Generally, the folding door is preferably one that is hung from the top and can support the first connecting frame in a cantilever manner, but it can also be applied to, for example, a panel shutter that is vertically foldable by hanging a wire and is not necessarily hung from the top. It does not have to be limited to the expression type.

Further, it is possible to arbitrarily set the plate to be installed in the door pocket portion, the guide rail to be curved or S-shaped, and as will be apparent from this point, in carrying out the present invention, the door pocket portion, Specific shapes such as guide rails, first cutout openings, second cutout openings, opening frames, panels, connecting frames, swing stops, suspension frames,
The structure, size, material, number of members, arrangement, and their relationship can be variously modified without departing from the gist of the invention.

[Advantages of the Invention] Since the present invention is configured as described above, as described in the action column, two panels are surely shaken from the end of the door pocket side where the upper end is not held by the guide rail of the upper frame even in the closed state. It can be stopped, and the flap of the panel in the door pocket can be prevented.

For this swing stop, it is sufficient if the swing stop is inserted into the second cutout opening by the closing rotation of the panel and the panel is moved in the opening / closing direction while being extended. Without needing, the natural lateral pulling operation for closing the panel and the series of movements can also complete the swing stop, and the operation is not complicated, and as a result,
It can be easily adopted for folding doors that open and close automatically.
