Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a rail device, and in particular, to a folding overhead shutter,
This article relates to a rail device for folding doors that can be applied to indoor folding partitions, folding doors, etc. whose door body opens and closes by folding.

(Background technology) Conventionally, for example, a folding top-hung shutter was developed using the
As exemplified in No. 663 and Utility Model Application Publication No. 59-122368, the upper and lower ends of each shutter door body are inserted into the upper and lower rails in a wrap-around manner, and each such shutter door body runs on a doorway. It is rotatably connected to the upper hanging connection frame, and -
The shutter door body was constructed by cutting out the upper and lower rails at the side end and providing a plate plate so that the shutter door body could be successively removed from the upper and lower rails and folded.

For this reason, with this type of folding overhead shutter, all the shutter doors are moved to the door pocket side and folded one after another, making it difficult to open and close, and the entire shutter must be pushed open to get a small opening. On the other hand, since the door pocket was essential, an unnecessary plate plate had to be installed at all times when the shutter was opened.

(Object of the Invention) The present invention replaces such conventional folding doors by eliminating the need for a door pocket and allowing only the necessary doors to be folded and opened. It is an object of the present invention to provide a rail device for a folding door that is most suitable for a folding door that is stably held in the shape of a folding door. The upper and lower rail devices are composed of inner and outer rails, and the inner rail is inserted into the outer rail so that it can move freely in the longitudinal direction and can be inserted into the outer rail so that it can be inserted into the outer rail. This is carried out using a pressing force, and the movement and protrusion and depression of the inner rail are performed by a plurality of rotating arms that connect the inner soft rails. An elongated groove-shaped inner rail provided with pressure receiving portions at both ends is inserted into a groove of an outer rail that is slightly longer than the inner rail, and multiple rotations are made in the longitudinal direction between the inner and outer rails. The arms are installed and fixed in a spaced manner, and the inner rail can be freely moved and retracted in the longitudinal direction within the fixed outer rail, and the pressing receiving part of the inner rail is a pressing part of a folding door guided in the inner rail groove. The gist of this invention is a rail device for a folding door, which is characterized in that it can freely come into contact with the rail device.

The present invention will be described below with reference to drawings showing embodiments.
In the figure, 1 is a rail device for a folding door according to the present invention, and in this embodiment, the rail device 1 includes an inner rail 3 at a lower frame position of a folding door 2.
It is formed with an outer rail 4 and a rotating arm 5.

The folding door 2 of this example has ten door bodies 10 arranged side by side within a frame formed by framing the upper and lower frames 6 and 7 and the left and right vertical frames 8 and 9 around the four sides. This door body 10 has upper, lower, left and right frames 11.
12.13.14 and the middle band 15 are assembled into a frame, and a glass panel 16 is fitted and held therein, and a connecting part 17 is arranged between each door body 10, and the left and right adjacent door bodies 10 are connected to this. .10 are rotatably connected with a hinge (connection part 18). The connecting portions 17 are provided with an upper hanging door wheel 19 at every other upper end and are suspended upwardly and supported on the guide rail 20 of the upper frame 6 so as to be freely movable. 21 to be inserted and guided into the inner rail 3 which will be described next. Note that steady rest members 22 are provided at the upper and lower ends of the other connecting portions. In this way, the door body 10, which has 10 hinges connected through the connecting part 17 and is suspended from the upper frame so as to be freely movable, can be folded into a bellows shape and opened and closed by pulling it horizontally from side to side. It becomes.

The inner rail 3 and the outer rail 4 together form a lower frame 7 of the folding door 2.

That is, the inner rail 3 is a long groove-shaped member, and its cross-sectional shape is formed by integrally connecting the lower portions of the front and rear side plates 23 and 24 with a horizontal connecting bottom plate 25, and forming an approximately H-shaped or inverted U-shaped upward opening. In addition to forming a soft groove 26, the front and rear side plates 23.2
The upper ends of the grooves 4 are formed by integrally molding the front and rear horizontal fin portions 27 and 28, which extend horizontally in the front and rear (i.e., outward with respect to the groove opening). After being integrally molded into a long cross-sectional shape, pressure receiving portions 29 are provided at both ends in the longitudinal direction. The pressure receiving part 29 is made of an extruded aluminum alloy material having a U-shaped cross section, and is cut into a relatively short length to match the groove depth of the inner soft groove 26.
Insert into both ends of the inner soft groove 26 in the longitudinal direction and attach with screws (3 in the figure).
0) and is integrally provided with the inner raceway 3.Next, the outer raceway 4 is a groove-shaped material formed by extrusion molding of an aluminum alloy, and is slightly longer than the inner raceway 3, and its cross-sectional shape is From the front and rear ends of the bottom plate 310 to the front and rear side plates 32.33
The upper ends of the front and rear side plates 32 and 33 are respectively extended slightly inside the groove opening to form the front and rear horizontal fin portions 35. .36 is integrally molded. In addition, outer rail 4
has both longitudinal ends fitted into the lower ends of U-shaped groove-shaped left and right vertical frames 8.9, and is fixed with tapping screws 37 to form a framework.

The inner rail 3 is fitted into the groove 34 of the outer rail 4. That is, the front and rear opening width of the outer rail groove 34 is formed to be slightly wider than the outer dimensions of the front and rear side walls of the inner rail 30, so that the inner rail is inserted from above, and the horizontal fin portions 27 and 28 of the inner rail 3 are connected to the outer rail 4. horizontal fin portion 35.
It can be placed freely on 36.

Note that since the outer rail 4 is slightly longer than the inner rail 3, the inner rail 3 fitted into the outer rail groove 34 can move somewhat in the longitudinal direction. Here, the difference in the longitudinal dimensions of the inner soft strips 3 and 4 is set to be equal to or greater than the horizontal component of the amount of rotation of the rotating arm 50, which will be described later.

Furthermore, a series of bulges 38 are formed in the longitudinal direction toward the inner side of the groove opening at the tips of the horizontal fin portions 35 and 36 of the outer rail 4,
Even when the fitted inner rails 3 come into contact, this is a linear contact to reduce the friction between the inner soft rails.

A plurality of rotating arms 5 are mounted and fixed in a spaced manner in the longitudinal direction between the inner and outer rails 3 and 4 that are fitted together in this manner.

That is, the rotating arm 5 of this embodiment is made of a relatively thick stainless steel plate, and has rotating arms on the inner surfaces of the front and rear side plates 32 and 33 of the outer rail 4 and on the outer surfaces of the front and rear side plates 23 and 24 of the inner rail 30, respectively. It is mounted and fixed in a movable manner by being attached to the shaft (the shaft attachment portion 39). Further, the arrangement is such that two of them are spaced apart from each other near both ends in the left and right longitudinal directions in the outer rail groove 34, and two of them are provided on each side of the front and rear across the inner rail 3, that is, a total of four
It is attached to a specific location.

Here, the rotation of the rotation arm 5 in this embodiment is such that it can freely rotate upward from an angle equal to horizontal t plus an elevation angle, with the shaft attachment portion 39 to the outer rail 4 as a fixed point. It is said to extend to an angle slightly beyond the apex. At this time, the inner rail 3 is guided by the rotating arm 5 and can freely protrude from the outer rail groove 34 while maintaining the horizontal position due to the rotation of the shaft attachment portion 390. Further, the rotating arm can stop further rotation at an angle slightly exceeding the above-mentioned apex by abutting against a stopper (not shown) or the vertical frame 9 of the inner rail 3.

Of course, the inner rail 3 can be freely retracted into the outer rail groove 34 by the reverse rotation guidance of the rotary arm 5, and when the retraction is completed, the rotary arm still has a certain elevation angle with respect to the horizontal as described above. I'm leaving it behind. Note that 40 in Figure 1 is a synthetic resin washer that is inserted as necessary to prevent electrolytic corrosion and improve sliding properties.

By the way, the connected door body 10... is allowed to move freely in the opening/closing direction between the left and right vertical frames 8 and 9 by the horizontal component of the amount of rotation of the rotating arm 5 or more than that while in the extended state. In this embodiment, the left end hanging stile 42 has this amount of movement (clearance) within the left vertical frame 8. Here, the hanging frame 42 is urged in the closing direction by a later-described urging device 50 interposed between it and the left vertical frame 8, but it is impossible to pull it laterally against this urging force. The above-mentioned movement is possible by relying on the biasing force or, conversely, by relying on the biasing force.

On the other hand, the press receiving portion 29 of the inner rail 3 is connected to the inner soft groove 26.
It can freely come into contact with the pressing part 41 of the folding door 2 guided inside.

That is, in this example, the pressing part 41 of the folding door is the left end hanging frame 42 and the right end door stop, which are rotatably hinged to the left and right doors (connecting part 18) of the connected door bodies 10... This corresponds to the lower end portions of the stile 43, which can freely come into contact with the press receiving portion 29 of the inner rail 3. Here, both the hanging frame 42 and the door stop frame 43 that span the pressing part 4 of this example are provided with an upper hanging door wheel 19 at their upper ends, and are suspended upwardly and supported on the guide rail 20 of the upper frame 6 so as to be freely movable. , is an upper suspension support end stile that runs within an inner soft groove 26 via a guide roller 21 provided at its lower end.

By the way, to explain the operating state of such a track device 1, first, when closing the folding door 2, the right end door stopper stile 43
was pulled horizontally in the closing direction to extend each door body 10 that had been folded into a bellows shape, and furthermore, the pressing part 4 of the door stop stile 43 was
1 is brought into contact with the press receiving portion 29 of the inner rail 3 and pressed. As a result, the inner rail 3 moves within the outer rail groove 34 in the direction of closing the door body, but at this time, the inner rail 3 is projected upward from the outer rail groove 34 due to the upward rotation of the rotating arm 5. . Then, every other connecting stile 17 is placed in the inner rail groove 26.
With the guide roller 21 provided at the lower end of the door body 1o
A steady rest member 22 provided at the lower part of the lower stile 12 and the lower end of the other connecting stile 17 is fitted (see FIG. 3).

On the other hand, when opening the folding door 2, by pulling any door body 10 or the right end door stopper stile 43 horizontally in the opening direction, the left end hanging stile 42, which is the other pressing part 41, will be opened on the left side of the inner rail 3. It comes into contact with the pressure receiving part 29 and presses it. As a result, inner rail 3
moves in the outer track groove 34 in the opening direction of the door body 10,
At this time, the inner rail 3 is recessed and stored in the outer rail groove 34 by the downward rotation of the rotating arm. Although the guide rollers 21 provided at the lower ends of every other connecting stile 17 still remain fitted in the grooves, the lower stile 12 of the door body 10
The swing stop members 22 provided at the lower part of the connecting frame 17 and the lower ends of the other connecting frames 17 are simultaneously released from their fitted states over the entire range (see FIG. 4). As a result, the single connecting stile 17 that is suspended above and equipped with the guide roller 21 at the lower end is guided by the inner groove 26 and is movable in the opening direction, and also The connecting frame 17 can be detached from the inner groove 26 at any position and protrude forward or backward, and each door body 10 can be folded into a bellows shape (
(See Figures 4 and 5). In addition, 51 in the figure is the ground level, and the front and rear horizontal fin parts 35, 36 of the outer rail and the front and rear horizontal fin parts 2'128 of the inner rail recessed in the outer rail groove 34 are almost flush with this. There is.

In this example, the upper frame 6 is also provided with a rail device similar to the rail device that operates in the opposite direction to the rail device of the lower frame (see FIGS. 3 and 4), and 44 in the figure is Inner rail in Kamiazusa (however, this inner rail 44 does not fit and hold the end of the door body 10 in the groove, but is attached to the upper end of the door body from either front or rear), 4
Reference numeral 5 indicates an L-shaped angle serving as a pressure receiving portion provided at both ends of the inner rail 44 in the longitudinal direction, 46 indicates an outer rail, 47 indicates an outer rail groove, and 48
49 is a synthetic resin washer that is interposed as necessary, and the rotating arm 5 is provided near both longitudinal ends of the outer rail groove 47. On the other hand, numeral 50 in FIG. 5 is a leaf spring type biasing device, and the nucleus pulposus biasing device 5
0 is interposed between the left end hanging stile 42 and the left vertical frame 8, and biases the door body 1o in the closing direction. As a result,
When extended and closed, each door body 10 is always pushed in the closing direction, and the pressing portion 41 of the right end door stopper stile 43 continues to press the pressing receiving portion 29 of the inner rail 3. Become. Therefore, the inner rail 3 will not return to the opening direction and fall due to unexpected force such as vibration, and the door body 10 will not open unexpectedly. On the other hand, when the door body 10 is to be opened, the inner rail 3 may be reversely operated by pulling the door body 10 and the door stop stile 43 sideways with a force that exceeds this biasing force. In addition.

If the door body 10... is simply opened, the biasing device 5
0 is limited, and the left end hanging frame 42 is regulated and housed within the left vertical frame 8, so the amount by which the opened door body 10 is pushed back is small. , folding door 2
The aperture width is maintained sufficiently. Of course, since the inner rail 3 has no direct relationship with the biasing device 50, it maintains the lowered state when the door body 10 is in the open state.

As for the arrangement of the rotating arms, in addition to installing them at a total of four locations in the outer rail groove as shown in the illustration, for example, in the longitudinal direction of the same groove, they are installed only at the center, and near both ends in the left and right longitudinal directions. It is also possible to arrange it at only two locations in total. Of course.

They may be arranged not only at both ends in the longitudinal direction, but also at a plurality of positions spaced apart from each other at intermediate positions.

Further, the pressing part of the folding door may be an end stile component such as an airtight material or a door stop block made of synthetic resin fixed thereto, in addition to the above-mentioned hanging support end stile.

On the other hand, the pressure receiving part provided on the inner rail only needs to be able to receive the opening/closing force of the folding door guided in the inner rail groove, for example, L
A shaped angle member may be secured to the end of the inner groove so as to traverse the longitudinal end opening of the inner groove.

In addition, in order to avoid dust and mud clogging and maintain smooth operation of the rotating arm over a long period of time, it is desirable to use a bearing with a bearing for mounting and fixing the rotating arm, or to strengthen the seal.

Next, there are various forms of folding doors equipped with such a track device, such as one in which the upper hanging door wheel and lower end guide roller of the door body are guided in a straight line as shown in the example shown in the figure, as well as one in which the inner and outer rails of the upper and lower frames are guided in a circular arc. It is also possible to guide it along a curved line. When the folding door is to be opened with both hands facing each other, the rail devices may be arranged to face each other on the left and right, and when the door is to be installed in tandem, they may be arranged in series. Additionally, the rail device of the present invention can be applied not only to a door having a large number of door bodies as shown in the figure, but also to a folding door having two door bodies, such as a folding door for a bathroom.

Note that the rail device of the present invention may be formed only on the lower frame or the upper frame of the folding door, or a similar device may be provided on the upper and lower frames. Here, when the rail device is formed only on one of the upper and lower frames, it is used as a means for separating the upper and lower ends of the door body from the other frame.

A structure in which the front or rear wall of the holding frame, which is the end of the door body, can be moved up and down to open and close may be appropriately selected and used.

Although the embodiments are configured as described above, the present invention does not depart from the scope of the above-mentioned gist. It goes without saying that the material, number of members, arrangement, relationship among these, etc. can be changed in various ways, and are not limited to the above embodiments.

(Effects of the Invention) In the switchgear of the present invention, the long groove-shaped inner rail provided with pressure receiving portions at both ends in the longitudinal direction is inserted into the groove of the outer rail, which is slightly longer than the inner rail. At the same time, a plurality of rotating arms are installed and fixed in a spaced manner in the longitudinal direction between the inner and outer rails, so that the inner rail can be freely moved and retracted in the longitudinal direction within the fixed outer rail, and the pressing receiving portion of the inner rail is Since it can freely come into contact with the pressing part of the folding door guided in the inner rail groove, the folding door guided in the inner rail groove can be closed by the protrusion and depression of the inner rail by the rotating 7-m. In the closed state, the end of the door body is stably held in the inner rail groove in a wrapped state, and when opening, the holding state can be released as a whole, so all the door bodies can be moved toward the door compartment side. There is no need to move and fold them one after another; for example, they can be folded from the door stop side. Therefore, only the necessary number of sheets can be opened to go in and out, and they can be opened and closed easily. .

In addition, since the holding state of the body can be released as a whole in this way, there is no need for a special door pocket that recesses the floor and installs a door pocket plate, and when the folding door is closed, There is no dead space along the entire length near the door (floor space can be used effectively).

Furthermore, if the rail device of the present invention is used, it is possible to form a folding door that runs in a curved shape, and the holding state of the door body can be released as a whole, so even if the rail device has such a curved shape, the folding door can be formed. It can be opened and closed easily.

Further, in the rail device of the present invention, the pressure receiving part of the inner rail can freely come into contact with the pressing part of the folding door guided in the inner rail groove, so that the protrusion and depression of the inner rail is prevented by opening and closing the folding door. This operation is performed using the pressing force of the folding door, and the operation can be performed in series with the horizontal pulling operation of the folding door, making it easy to use.
