Description

[Detailed Description of the Invention] Purpose of the Invention (Industrial Field of Application) This invention relates to a shoji opening/closing device that supports a plurality of shoji screens in series when the windows are closed by sliding the windows apart.

(Prior art) Usually, multiple shoji installed on a window are configured to open and close the window by sliding them on different sides, so the frame supporting the shoji has at least the width of two shojis. However, as shoji shoji themselves have become thinner in recent years, each shoji, which normally operates in a sliding state, is supported flush in series when the window is closed, reducing the width of the frame to two shojis. A width smaller than the minute width has been proposed.

This type of shoji opening/closing structure was developed in the 1980s, for example.
Disclosed in Publication No. 61375 or Publication of Utility Model Application No. 59-158671, by attaching the shoji to the door roller via a rotating arm, the shoji is rotated relative to the door roller, and each shoji is in a series state. Each shoji can be moved back and forth, or by attaching support rollers to the vertical frames of the shoji and providing guide members on the vertical frames on the sides of the shoji, and moving the support rollers along the guide members. were moved so that they were in series.

(Problem to be solved by the invention) In the structure in which the shoji are moved in series as described above, the upper stile is also movable back and forth relative to the upper frame of the window as the lower stile of the shoji is moved. It is becoming. However, since the upper stile is usually located above and difficult to reach, there is a problem in that it is difficult to reliably move it to the double-sliding position or the serial position.

Structure of the invention (Means for solving the problem) In order to solve the above problem, this invention opens and closes the window by sliding multiple shojis, and when the window is closed, the specified shojis are moved in front and behind the window. In a sliding sash that supports each shoji in series by moving in the direction, the upper stile 1c of the shoji 1 is moved in the front and back direction of the window.
At least a pair of elongated holes 34 are provided in the longitudinal direction of the stile 1c, and base ends of a pair of arms 36a, 36b are movably and rotatably supported along the elongated holes 34, and both arms 36a, 36b are supported. The tips of the arms 36 are rotatably connected to each other with a pin 39.
The arms 36a and 36b are made to be able to rotate back and forth around the pin 39 from the state in which the arms 36a and 36b are in a straight line, and the guide member 40 that protrudes into the guide recess 41 of the upper frame 3a of the window frame is attached to the pin 39. When attached, the pin 39 can be moved only in the longitudinal direction of the upper frame 3a, and the base ends of both arms 36a and 36b are connected by a coil spring 38 and biased toward each other.

(Function) When the shoji 1 is moved in the front-back direction by the above means, the upper stile 1c of the shoji 1 is automatically moved to either the serial position or the double sliding position by the biasing force of the coil spring 38.

(Embodiment) Hereinafter, an embodiment embodying this invention will be described with reference to the drawings. A blind 5 is suspended from the back side of the glass 4, and the angle of the slat 9 can be adjusted via a ladder cord 8 by operating an operating knob 7 provided in the handle 6 of each shoji 1, 2. I'm starting to be able to do it. In addition,
On the outside of each shoji 1 and 2 (on the left side in FIG. 4), a pair of sliding shojis (not shown) are usually arranged, and together with the shojis 1 and 2, they form a double sash.

The vertical stile 1a of one shoji 1 has a handle 11a,
11b are rotatably provided, and by moving the shoji 1 outward from the state where the window is closed with both shoji 1 and 2 as shown in FIGS. Shoji 1 and 2 are supported in series within a window frame 3. From this state, if the handles 11a and 11b are rotated in the vertical direction shown in FIG.
1 and 54, the shoji 1 is fixed to the upper frame 3a, the vertical frame 3b of the window frame 3, and the vertical stile 2a of the other shoji 2.

Next, the structure for supporting the shoji 1 and 2 in series within the window frame 3 will be explained. In the shoji 2, the door roller 12 provided on the lower stile 2b is provided on the lower sill 3c of the window frame 3. A guide member 14 that moves on a rail 13 and projects upward from the upper frame 2c moves within a guide recess 15 of the upper frame 3a. Therefore, the shoji 2 is supported so as to be movable only in the left-right direction within the window frame 3 along the rails 13.

The shoji 1, which moves in the front-rear direction with respect to the shoji 2, has a pair of rollers 17, which move only in the left-right direction within a guide groove 16 on the lower frame 3c, attached to the left and right sides of the lower stile 1b. The detailed structure is explained below.
As shown in FIG. 7, the mounting member 18 for attaching the roller 17 to the lower stile 1b has horizontal bent pieces 19a and 19b formed at both upper and lower ends thereof, and the lower bent piece 19b is slightly upwardly bent. A mounting piece 20 is formed which also protrudes in the horizontal direction. Then, as shown in FIG. 6, the upper bending piece 19a and the mounting piece 2
As shown in FIG. 7, it is fixed to the lower frame 1b with screws 22 through screw holes 21 provided in the lower frame 1b.

A first pivot shaft 23 is fixed between the upper and lower bent pieces 19a and 19b, and the pivot shaft 23 is connected to the connecting body 2.
4 and supports the connecting body 24 so as to be rotatable in the horizontal direction. A second rotation support shaft 25 is rotatably inserted into the other side of the connecting body 24, and a roller case 26 is fixed to the lower end of the second rotation support shaft 25. Further, a screw 27 is screwed into a screw hole 28 above the second rotation support shaft 25, and by screwing the screw 27 into the screw hole 28, the second rotation support shaft 25 is connected to the connecting body 24. The length exposed from the shoji 1 can be adjusted, and the distance between the shoji 1 and the lower frame 3c can be adjusted by adjusting the screws 27.

The base ends of a pair of roller shafts 29 for supporting the rollers 17 are fixed to the roller case 26,
The tip of the roller shaft 29 is projected toward the rail 13, and the roller shaft 29 is attached to the center of the roller 17 so as to be movable in the axial direction. As shown in FIG. 2, an insertion hole 30 is formed in the rail 13 at a position facing the roller 17 of the shoji 1 when the window is closed with the shoji 1 and 2, as shown in FIGS. 5 and 8. A sealing member 31, which is formed by bending both sides of the metal plate downward at right angles and having approximately the same dimensions as the insertion hole 30, is inserted into the insertion hole 30 in the direction of arrow A in FIG. As shown, it is fitted between the rail 13 and the lower frame 3c to maintain airtightness around the insertion hole 30. In addition,
A plurality of hook portions 32 are provided on one side of the sealing member 31 and are extruded outward, and as shown in FIG. 5, once the sealing member 31 is inserted into the insertion hole 30, the hook portions 32 are It comes into contact with the peripheral edge of the insertion hole 30 of the rail 13 and cannot be easily removed.

When the shoji 1 supported by the rollers 17 as described above is pushed in the direction of arrow B in FIG. It penetrates through the insertion hole 30 and protrudes into the sealing member 31, and the roller case 26 and the mounting member 18 move accordingly, so that the shoji 1 itself is moved in the same direction. Further, if the shoji 1 is further pushed in the same direction from the state shown in FIG. Since it is rotatably supported on the support shafts 23 and 25, the mounting member 18 moves in the direction of arrow C from the position shown by the solid line in FIG. 9 to the position shown by the chain line, and along with this, the lower frame 1b moves in the same direction.

With the above operations, the lower stile 1b of the shoji 1 is moved from the position shown by the solid line in FIG. 5 to the position shown by the chain line,
This chain line position coincides with the movement locus of the other shoji 2 moving on the rail 13. Therefore, in this state, the shoji 1 and 2 are supported in series within the window frame 3 as shown in FIG. In addition,
When the shoji 1 is pushed in the direction of arrow B in FIG. 5, the movement of the roller shaft 29 and the rotation of the connecting body 24 do not necessarily operate separately, but may operate in parallel at the same time.

The upper stile 1c of the shoji 1 is supported by the upper stile 3a of the window frame 3, and similarly to the lower stile 1b, it is supported so as to be movable along the movement trajectory of the shoji 2. To explain its structure next, as shown in Fig. 11, the upper frame 1c
A mounting bracket 33 is fixed to the mounting bracket 33 .
The middle part of the mounting bracket 33 is bent upward into a rectangular shape, and elongated holes 34 are provided near both sides of the middle part along the longitudinal direction of the mounting bracket 33, as shown in FIG. The base ends of arms 36a, 36b are rotatably attached to the upper ends of pins 35a, 35b that are movably passed through the respective elongated holes 34, and the lower ends of the pins 35a, 35b are attached to connecting fittings 37. They are connected via a coil spring 38 and biased toward each other. The tips of the arms 36a, 36b are rotatably connected by a pin 39, and a guide member 40 is rotatably attached to the top of the tips of both arms 36a, 36b by the same pin 39. And the guide member 40
is located within a guide recess 41 provided in the upper frame 3a of the window frame 3, as shown in FIG. 10, and the upper end of the shoji 1 is moved along this guide recess 41.

Furthermore, when sliding the shoji 1 with respect to the shoji 2, the upper stile 1c of the shoji 1 is located in the state shown by the solid line in FIG. 10, and in this state, the arm 36
a and 36b are located in the state shown by solid lines in FIG. When the shoji 1 is pushed in the direction of arrow B in FIG. 5 from this state, the base ends of the arms 36a, 36b are moved in the direction of arrow D from the position shown by the solid line in FIG. 12 to the position shown by the chain line. At this time, both arms 3
Since the base ends of the arms 6a and 36b are always urged toward each other by the coil spring 38, the shoji 1 is pushed against the urging force of the coil spring 38, and the base ends of the arms 36a and 36b are pushed together. If it is slightly rotated in the opposite direction about the pin 39, the biasing force of the coil spring 38 will automatically rotate it to the range allowed by the elongated hole 34, that is, to the position shown by the chain line in FIG. Then, when both arms 36a and 36b are rotated about the guide member 40 to the position indicated by the chain line in FIG.
The upper end of the shoji 1 is positioned as shown by the chain line in FIG. 10, and this position coincides with the locus of movement of the other shoji 2.

A base end of a stopper 42 of the shoji 1 is rotatably supported on one side of the guide member 40. Then, the retainer 42 is pushed upward from the state shown by the chain line in FIG. 11 to the state shown by the solid line using a screw 43 passing through the guide member 40 from below, and is projected to the vicinity of the upper limit of the guide recess 41, causing the shoji 1 to move upward. The shoji 1 is prevented from being easily removed from the window frame 3 by being prevented from being lifted up. In addition,
If the shoji 1 is moved to the position shown by the chain line in FIG. 10, the guide member 40 will be exposed in front of the shoji 1, so the screws 43 can be easily adjusted in this state.

The shoji 1 is provided with a fixing device for holding the shoji 1 in series with the shoji 2. The structure will be explained next. The handles 11a and 11b provided on the vertical stile 1a of the shoji 1 are rotatably supported with respect to the vertical stile 1a. As shown in FIG. 14, the handle 11a provided on the shoji 2 side in FIG. . A rack 48 meshing with a gear 45 is disposed within the stile 1a, and the rack 48 is welded to an angular transmission member 49 extending upwardly within the stile 1a. Then, the handle 11a is the first
When the gear 45 is rotated in the direction of arrow E from the state shown by the chain line in FIG. 3 to the state shown by the solid line, the gear 45 is rotated in the direction of arrow F in FIG. The member 49 is adapted to be moved upwardly within the stile 1a.

Furthermore, when the handle 11a is rotated in the direction of arrow E from the state shown by the chain line in FIG. 13 to the state shown by the solid line, the first locking piece 46 is rotated from the state shown by the chain line in FIG. 15 to the state shown by the solid line. At this time, the first locking piece 46 projects into the locking piece 50 provided on the vertical stile 2a of the other shoji 2.

As shown in FIG. 17, a second locking piece 51 is attached to the upper end of the transmission member 49. As shown in FIG. When the transmission member 49 is moved upward, the second locking piece 51 projects into a locking hole 52 provided in the upper frame 3a of the window frame 3.

In FIG. 1, the left side, that is, the vertical frame 3 of the window frame 3
As shown in FIG. 16, the handle 11b provided on the b side has a gear 5 similar to the handle 11a.
3 and the third locking piece 54 are attached, and the handle 1
When 1b is rotated in the vertical direction, a third locking piece 54 projects into a locking hole 55 provided in the vertical frame 3b.

Next, the operation of the shoji 1, 2 configured as described above will be explained.

Now, as shown in FIG. 2, these shoji 1 and 2 can be opened and closed by sliding the windows in the same way as a normal shoji. At this time, the handles 11a and 11b of the shoji 1 are rotated in the horizontal direction so that the locking pieces 46, 51, and 54 do not protrude from the vertical stile 1a. Then, as shown in the figure, from the state where the window is closed with the shoji 1 and 2, the handles 11a and 1 are
1b and push the shoji 1 toward the outside of the window, that is, in the direction of arrow B in FIG. 5, the roller shaft 29 passes through the rail 13 and moves relative to the roller 17, as shown in FIG. At the same time, the connecting body 24 rotates about the second pivot shaft 25, and as a result, the mounting member 18 moves from the position shown in FIG. 6 to the position shown by the chain line in FIG. will be moved. Therefore, the lower stile 1b of the shoji 1 is moved from the position shown by the solid line in FIG. 5 to the position shown by the chain line.

Also, at the same time as the movement of the lower stile 1b as described above,
As shown in FIG. 12, the arms 36a and 36b attached to the upper stile 1c are rotated about the guide member 40 from the position shown by the solid line to the position shown by the chain line, and at this time the upper stile 1c is rotated as shown in FIG. It is moved from the position shown by the solid line to the position shown by the chain line.

Therefore, when the shoji 1 is pushed in the direction of the arrow in FIG.
As shown in the figure, the shoji 1 is moved from the solid line position to the chain line position, and this chain line position coincides with the movement locus of the other shoji 2.
It becomes a series state.

When both handles 11a and 11b are rotated downward from the above state to the vertical position, the first locking piece 46 locks into the locking hole 50 of the vertical stile 2a of the shoji 2, as shown in FIG. protruded inward, first
As shown in FIG. 7, the second locking piece 51 is projected into the locking hole 52 of the upper frame 3a, and as shown in FIG. protruded inward. Therefore, the upper stile 1c and both left and right vertical stile 1a of the shoji 2 are supported by the window frame 3 and the other shoji 1, and the shoji 2 is stably held in series with the shoji 2 shown in FIG.

On the other hand, when returning the shoji 1, 2 from the serial state to the alternate sliding state, the handles 11a, 11b are rotated in the opposite direction to the above, and each of the locking pieces 46, 51, 5
4 and the corresponding locking holes 50, 52, 55, and then grasp the handles 11a, 11b and pull them toward you to return to the double-sliding state shown in FIG.

As described above, in this support structure for the shoji 1 and 2, if the shoji 1 is pushed out to the outside of the window when the window is closed, the roller shafts of the rollers 17 supporting the shoji 1
9 moves relative to the same roller 17, and further the connecting body 2
4 rotates and the shoji 1 is moved. In order to move the shoji 1 to the locus of movement of the other shoji 2, linear movement by the movement of the roller shaft and the coupling body 2 are performed.
In order to utilize the rotational movement caused by the rotation of 4, the first rotation support shaft 23 during the sliding operation of the shoji 1
The amount of offset, that is, the distance L shown in FIG. 5, can be made smaller than in the conventional structure in which the shoji is moved only by the rotating arm. Therefore, the sliding operation can be performed in a stable state without rattling the shoji 1, and since rattling can be prevented, the shoji 1 can be prevented from accidentally falling off the window frame 3. can.

Furthermore, even when the shoji 1 is moved until it is in series with the shoji 2, the first and second pivot shafts 2
3 and 25 are not exposed outside the shoji 1, and the roller case 26 is only slightly exposed below the shoji 1, so this shoji 1 support structure does not spoil the aesthetics of the room.

On the other hand, the upper stile 1c of the shoji 1 has arms 36a, 36
b is supported so that it can move the same distance in the same direction as the lower stile 1b at the same time. And arm 36
a, 36b are held in either of the states indicated by solid lines or chain lines in FIG. 12 by the biasing force of the coil spring 38, so that the shoji 1 can be placed either in series with the shoji 2 or in the opposite sliding position. Not only can the shoji 1 be moved, but also the urging force of the coil spring 38 can prevent the shoji 1 from wobbling in the front-rear direction during the sliding operation.

In addition, in the above embodiment, the handles 11a, 11b
Although the locking pieces 46, 51, and 54 are operated by rotating the handle downward, each locking piece can also be operated by rotating the handle upward, and the roller 17 of the shoji 1 can also be rotated upward to operate the locking pieces 46, 51, and 54. It is also possible to change and implement it.

Effects of the device As detailed above, this device is an excellent device that can extremely easily and reliably move the upper stile 1c of the shoji 1, which is moved in the front-rear direction of the window, to either the serial position or the double-sliding position. be effective.
