Description

TECHNICAL FIELD The present invention relates to an opening / closing device for a folding door that is an opening member of a building.

[Prior Art] For example, in the folding door known in Japanese Patent Publication No. 50-27663, the guide rails of the upper and lower frames are cut out at the folding portion, and each panel is escaped from here to fold and open in order. There is.

Here, the cutout width of this guide rail is not only the total folding thickness of the panel, but also a width of two or more panels is necessary to extend the panel and introduce it into the guide rail when closed. Becomes Also, if the folded panel moves to the door stop side together with the suspension base frame, the above notch width will be substantially reduced, so that the suspension base frame should be fixed at a fixed position in the opening frame by the pivot. There is.

[Problems to be Solved by the Invention] However, if the guide rail is widely cut out in this way, at least two panels on the suspension side cannot be held by the guide rail even in the closed state, which may cause flapping due to wind pressure. Become.

On the other hand, in order to prevent this, the notch portion of the guide rail has a first notch portion having the above-mentioned predetermined width, and a swing-out insertion opening which is a notch edge portion which is notched further deeply and has a narrow width. In addition to forming the two stages, the long swing stop exceeding the first notch is projected on the two panels on the suspension side or the connecting frame between them, and this is extended and rotated. At the same time, after introducing it into the swing-out insertion opening which is the second cutout portion, if the entire swing-out panel is slid in the opening and closing direction and the swing-off is advanced into the guide rail, the panel can be held even in the folding portion. It will be possible. However, on the other hand, since the suspension frame can also be moved due to the sliding of the entire panel, it is not possible to fix the suspension frame in place as described above, and if the end panel is folded and the suspension frame is pulled sideways. In particular, there is a possibility that the position of the swing stop may be displaced with respect to the swing stop insertion port, which may hinder the introduction.

The present invention has been made in view of the above problems, and provides a folding door opening / closing device capable of smoothly opening and closing the end panel on the hanging base side at a fixed position while adopting a movable hanging frame. With the goal.

[Means for Solving the Problems] The present invention has been completed in accordance with the above object by separating the relationship between the suspension base frame and the pivot position of the end panel, that is, the present invention is
A suspension base frame that is movable in the opening / closing direction, a suspension base side end panel in which a pivoting frame is rotatably connected to a joint hinge of the suspension base frame, and a pivot provided on the end panel. The width of movement of the suspension base frame relative to the kicked-out portion in the open state, which is within the width of the kicked-out portion protruding to the opposite side of the drive shaft and the guide rail cutout opening for panel escape in the folded portion. A folding door opening / closing device, characterized by comprising a kicking part provided at a fixed position of an opening frame separated within a minute and an abutting contacting part, and the gist thereof. is there.

[Operation] When each panel is extended in sequence from the door stop side, the end panel finally leans against the impact portion of the fixed position with the suspension frame being connected, and the kick portion is brought into contact with it.

Then, the abutting portion presses the kick-out portion projecting to the opposite side of the rotation axis of the end panel, and applies a moment in the closing direction coaxially to the end panel to forcibly rotate at a fixed position. Excuse me.

If the end panel rotates to the closing angle that follows the opening and closing direction,
The kick-out portion projecting to the opposite side of the rotation axis also becomes parallel to the opening / closing direction, and the contact with the abutting portion is released.

In the state where the contact is released, the end panel and the suspension base frame connecting the end panel are connected to each other in accordance with the clearance between the opening frame width and the panel full length width, or if the movement width of the suspension base frame is restricted. It is movable in the opening / closing direction within the width.

The horizontal door roller 16 engages with the upper frame 17 when the folding door 1 is closed, and is shaken after the closing. The stop 18 is adapted to engage the lower frame 19. However, among these, a swing stop 20 is provided above the second connecting frame 6 between the suspension-side end panel 4a and its adjacent panel so as to project upward relatively long.

The opening frame 2 is made of the same aluminum alloy extruded material, is provided with the above-mentioned upper frame 17, lower frame 19 and left and right end frames 21, 21, and is framed in a horizontally long rectangular shape. The folding part 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 upper frame 17.
The above-mentioned support door car provided with the first guide rail 22 in the shape of a shallow groove
The first guide rail 23 is provided with a second guide rail 24, which is a vertically elongated groove, below the first guide rail 23. The second guide rail 24 allows each second connecting frame 6 to be supported. While running the horizontal door car 16 of
In the folding portion 22, the rear side thereof is cut off for a total length 1 of the folding margin 1 of the folding door 1 and the lateral width l2 of two panels and the guide rail cutout opening for panel escape. 25 is provided. Furthermore, the upper edge of the cutout opening 25 is cut into a width smaller than that of the cutout opening 25 to provide a swing-in / out port 26.

Here, the upper ends of the respective panels 4 and the horizontal door roller 16 above the second connecting frame 6 are positioned within the cut-out height of the guide rail cut-out opening 25, while the suspension-end-side end panel 4a. The swing stop 20 that protrudes from the upper end of the swing stop 20 is provided within the height of the above-mentioned swing stop inlet / outlet 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 hanging side or the door stop side, the small door wheels 33, 33 are reversed from the blocks 35, 35. The movable frame 28 is configured to be inclined and to be projected and retracted by being guided by the V-shaped inclined guides 36, 36.

By the way, in the folded portion 22 in which the guide rail cutout opening 25 is provided in the upper frame 17, the fixed 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 circumferences, and to prevent the glass 3 from being caught in the opening / closing surface of the folding door 1, the center of the upper and lower frames 17, 19 and the end frames 21, 21. On the other hand, while displacing to the front side and fixing them with screws, a cutout 40 is provided in the upper frame 39 of this fixed panel 37, and the cutout end portion from the end frame 21 on the suspension side is described above. The kicking-out portion 13 provided so as to project from the end panel 4a on the suspension base side at a fixed position separated by the movement width of the suspension base frame 7.
A block-shaped contact portion 41 made of a synthetic resin is provided with a screw so as to be freely contactable with.

By the way, to explain the open / closed state of the folding door 1,
When the folding door 1 folded in the folding portion 22 is pulled laterally to extend the panels 4 in order, the horizontal door carriage 16 provided above the upper ends of the panels 4 and the second connecting frame 6 is provided as an upper frame 17 The guide rails are introduced into the second guide rail 24 in order from the end of the guide rail cutout 25. Reference numeral 42 in the figure denotes a guide roller for introducing the upper end of the panel, which is provided at the end of the guide rail cutout 25. Then, finally, the suspension-side end panel 4a leans against the abutting portion 41 installed at a fixed position while the suspension frame 7 is still connected, and the kicking portion is brought into contact with it.

When this is pulled further sideways, the abutting portion 41 becomes the end panel 4a on the hanging side.
The push-out portion 13 projecting to the opposite side of the rotating shaft 14 is pressed to give a moment in the closing direction around the rotating shaft 14 to the hanging end side end panel 4a to forcibly rotate at a fixed position. The swing stop, which is swung and protrudes to the upper end of the suspension side end panel 4a by this rotation, is inserted into the swing stop inlet / outlet 26 of the upper frame 17. Incidentally, reference numeral 43 in the figure denotes a synthetic resin guide piece for introducing a swing stop provided at the swing stop inlet / outlet 26.

When the hanging end side end panel 4a 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 abutting portion 41. Remove the contact of.

In the state where this contact is released, the suspension base side end panel 4a and the suspension base frame 7 that connects the suspension base side end panel 4a and the suspension base frame 7 are connected between the left and right end frames 21 and 2 of the opening frame 2.
The clearance between the inner width of 1 and the full length of the panel or the movable width of the hanging frame 7 is used to make the hanging end side end panel.
When the 4a is moved together with the suspension base frame 7 in the closing direction, the relatively long swing stop 20 inserted into the swing stop entrance / exit 26 is displaced from the entrance / exit and is housed in the upper frame 17. As a result, even at the time of closing, the suspension-side end panel 4a located within the cutout width of the guide rail cutout opening 25 of the upper frame 17 and the second panel 4 adjacent thereto
Will also be blocked.

From this point of view, the relatively long swing stop 20 that can be inserted into the swing stop insertion port is not limited to the suspension end side end panel, but the second panel adjacent thereto or the second connection between them. It may be arranged on the upper portion of the frame 6, and the guide rail cutout 25 may be opened at a position corresponding to this.

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 the hanging end side end panel 4a and the second panel 4 adjacent thereto are swayed on the end panel 4a. Is separated from the swing-out entrance / exit 26 along the guide piece 44 for lead-out and folded, and in the following order, the upper end of each panel 4 and the second connecting frame 6 ...
The folding door 1 is folded after being separated from 25. Note that, in this folding operation, the guide portion 44 guides the hanging end side end panel 4a so that the abutting part 41 does not hinder the rotation of the kicking part 13 of the hanging end side end panel 4a. Absent.

Although not shown, 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 end panel on the hanging side. In the case of integrally molding the rotary frame, one of the side walls having the U-shaped glass holding groove may be integrally projected to the opposite side of the rotary shaft. 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.

In addition, it is possible to arbitrarily set the plate to be installed in the folding portion, the guide rail to be curved or S-shaped, etc.
Suspension frame, joint hinge, swing frame, suspension side end panel, kicking part, folding part, guide rail cutout port, concrete shape, structure, dimensions, material, number of members, arrangement and the like of these The relationship and the like can be variously modified without departing from the gist of the invention.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, as described in the action column, the suspension base frame is movable, and the end panel remains in the folded state even if the suspension base frame is not fixed. It can be forcibly turned into a closed state at a fixed position without moving.

As a result, not only is it possible to smoothly open and close the suspension base frame to the end panel on the suspension base side, but it is also possible to use the end panel or its adjacent panel, or the connection frame between both panels. When a swing stop is provided, it can be accurately aligned with the insertion opening of the guide rail, rotated and inserted, and can be further advanced into the rail, so that flapping of the panel at the folding portion is prevented. It is also possible.
