Thereby, a stable simultaneous sliding state can be maintained. To return to the individual slide state, the knob 38b may be removed from the stop groove 36b.

FIG. 5 relates to a different form of coupling means.
FIGS. 7A and 7B show a connecting means 40 having a rotating connecting piece 64. Rectangular through holes 19a and 19b are formed in the vertical frame 16 of the shoji 10 (10b) on the indoor side on the inner and outer side walls. An operation handle 42 of the connecting means 40 is attached to the indoor side surface of the vertical frame 16 so as to be able to move up and down. The handle 42 is fixed to a guide plate 44 fitted in a pair of guide grooves 48 in a base plate 46 fixed to the vertical frame 16 via upper and lower horizontal pieces 43. In addition, the guide plate 4
A rack plate 50 having vertically continuous rack teeth 52 on the outer surface is connected to the outer surface of the unit 4 via a support piece 54 passing through the through hole 19a. Further, the guide plate 4
A pair of bearing plates 56 that pass through the through holes 19 a extend from the left and right side edges of 6 into the hollow portion 17 of the vertical frame 16.

A horizontal rotating shaft 58 is pivotally supported between the pair of bearing plates 56. On the circumferential surface of the cylindrical body 60 having the rotating shaft 58 as the center of rotation, the lower side in FIG. The pinion teeth 62 are provided at the closer position over a length of at least about a quarter thereof. Further, a connecting piece 64 having an outer surface extending along a tangent to the cylindrical body 60 is provided upright in the hollow portion 17 on a side substantially opposite to the pinion teeth 62 of the cylindrical body 60. On the other hand, on the indoor side surface of the vertical frame 22 of the outdoor sliding door 20 (20b), a recess
A receiving piece 66 having a receiving portion 8 is fixed in the same manner as described above.

Inner and outer shojis 10 (10b) and 20 (20b)
When the operation handle 42 is lifted upward to simultaneously slide the rack plates 50, the rack plate 50 also rises in synchronization with this. The rise of the rack plate 50 causes the rack teeth 52
Then, the pinion teeth 62 meshing with start to move, and rotate the cylindrical body 60 clockwise as shown by the arrow in FIG. By this rotation, the connecting piece 64 standing upright on the opposite side becomes the vertical frame 16
Through the through hole 19b, and is rotated approximately 90 degrees as shown by the arrow toward the outside of the room to be in a horizontal posture. Then, the connecting piece 6
4 is a receiving piece 66 having moved to the position indicated by the dashed line shown in FIG. 4 (B) and having its tip fixed to the vertical frame 22 of the shoji 20 on the outdoor side.
And is engaged in the recess 68. With such engagement, the inner and outer sashes 10b and 20b can simultaneously slide.
In order to keep this engaged state, it is desirable to provide a fixing means such as a stopper between the guide plate 44 and the base plate 46 so as to prevent the operation handle 42 from being inadvertently lowered.

Conversely, each of the shoji screens 10 (10b) and 20 (20b)

By using such connecting means 40,
The connecting piece 64 that engages and disengages between the inner and outer sashes 10 and 20 by rotation makes it possible to reliably switch between the states of simultaneous slide and individual slide by a simple operation. In addition, since the operation of raising and lowering the operation handle 42 is converted into rotation of the connecting piece 64 via the rack and the pinion, it is possible to compactly store the space inside the narrow hollow portion 17 of the vertical frame 16.

FIG. 5C shows a state in which a connecting means 70 having a further different form is used. Indoor sliding doors 10 (10b)
The vertical frame 16 has through holes 19a and 19b similar to those described above, and a pair of cylindrical bodies 74 and 82 constituting the connecting means 70 are horizontally mounted in the hollow portion 17 by rotating shafts 72 and 80, respectively. Gear teeth 76 and 86 meshing with each other are continuously provided on the opposed lower peripheral surfaces of the cylindrical bodies 74 and 82. A substantially L-shaped arm 7 passing through the through hole 19a is formed from a peripheral surface of the cylindrical body 74 on the indoor side substantially opposite to the gear teeth 76.
7 extends to the indoor side, and an operation handle 78 is vertically fixed to the end thereof. On the other hand, a connecting piece 84 extending along a tangent to the cylindrical body 82 is provided vertically from a peripheral surface of the cylindrical body 82 on the outdoor side, which is substantially opposite to the gear teeth 86.

Each of the inner and outer shojis 10 (10b) and 20 (20b)
When the operation handle 78 is turned to the indoor side downward at an angle of about 90 degrees to bring it to the horizontal position, the cylinder 74 rotates counterclockwise as shown by the arrow in the drawing, and The engagement of the teeth 76 and 86 causes the cylindrical body 82 to rotate approximately 90 degrees clockwise. For this reason, the connecting piece 84
After passing through the through-hole 19b, it rotates to the outside of the room by about 90 degrees to be in a horizontal posture, and is inserted into and engaged with the concave portion 68 of the receiving piece 66. Then, by pulling the handle 78 in the lateral direction,
Each of the shojis 10b and 20b can be slid simultaneously. Conversely, the inner and outer shojis 10 (10b) and 20 (2
0b), the operating handle 7
What is necessary is just to return 8 to the original vertical attitude. In any case, it is desirable to provide a fixing means such as a stopper as appropriate so as to keep the operation handle 78 in a horizontal and vertical posture so that it does not accidentally move.

FIG. 5D shows a different form of the receiving portion.
A receiving portion 94 is shown in which a pair of flanges 96 are vertically and integrally protruded toward the interior of the room on a hollow main body 92 of a vertical frame 90 of the outdoor sliding door 20 and a concave groove 98 is formed therebetween. Since the receiving portion 94 is formed integrally with the vertical frame 90 in advance, the receiving pieces 24, 6 are formed as in the above embodiments.
The trouble of fixing 6 becomes unnecessary. Incidentally, the pair of flanges 96 may be inserted into the concave groove 98 from the indoor side, and only the portion where the connecting pieces 34, 64, 84 to be engaged are located may be left, and the other portions may be cut off. Further, the concave groove 98 may have a sectional shape integrated with the main body 92 of the vertical frame 90.

FIG. 6 relates to a further different connecting means. FIG. 1A shows a connecting means 1 for performing adsorption and desorption using a permanent magnet.
It is a horizontal sectional view showing 00. Indoor sliding doors 10 (10
In the vertical frame 16 of b), a magnet piece 102 of a vertically long permanent magnet constituting the connecting means 100 is substantially incorporated. The magnet piece 102 is housed in a box-shaped housing portion 104 that opens to the outside of the room, and a horizontal rod 106 is connected to the inside surface of the room. The rod 106 protrudes toward the indoor side, and a knob 108 is fixed to an end on the indoor side. The sleeve 110 that supports the rod 106 so as to be movable in the horizontal direction is appropriately mounted together with the accommodation portion 104 between the through holes 19a and 19b of the vertical frame 16. On the other hand, an outdoor sliding door 20 (20b)
A vertically long plate piece 114 made of a ferromagnetic material such as iron and constituting the connecting means 100 is fixed to a position facing the magnet piece 102 with a screw 118 on the indoor side surface of the vertical frame 22.

The inner and outer shojis 10 (10b), 20
To slide (20b) at the same time,
Is pushed out of the room, the magnet piece 102 is
Also move outside. Then, the front end surface of the magnet piece 102 approaches and sticks to the plate piece 114, and a magnetic flux circuit is formed between the two. For this reason, since the inner and outer shojis 10b and 20b are connected via the plate piece 114, the magnet piece 102, and the rod 106, when the knob 108 is pulled in the lateral direction, the inner and outer shojis 10b and 20b can slide simultaneously. On the other hand, in order to make the slide state individually, the knob 10
What is necessary is just to pull back 8 to the outdoor side. In order to stabilize the illustrated individual slide state, it is desirable to appropriately provide a fixing means such as a stopper on the rod 106 or the like, for example. In addition, the mounting positions of the magnet piece 102 and the plate piece 114 are changed to the inner and outer vertical frames 16,
22 may be reversed. For example, a ferrite bonded magnet, a ferrite sintered magnet, Nd
Rare earth bonded magnets and the like are used.

Incidentally, in order to increase the above-mentioned attractive force, the magnet piece 10
2 may be substantially U-shaped in side view, and only the upper and lower horizontal portions may contact the plate piece 114. Further, the plate piece 114 to be attracted by the magnet piece 102 is formed into a substantially U-shaped section 116 in a plan view including a broken line in the drawing, and the magnet piece 102 is inserted into the recess and is attracted, so that the magnetic force is attracted. Both mechanical engagements can be used together. In this case, the magnet piece 10
2 can be made into a small piece, a thin piece, or a permanent magnet with low magnetic force. In order to maintain the magnetic properties of the magnet piece 102, non-magnetic stainless steel, an aluminum alloy, or a synthetic resin material is used for the material of the storage portion 104, the rod 106, and the sleeve 110. And each shoji 10b, 2
0b is also preferably made of aluminum material.

FIG. 6B is a longitudinal sectional view showing another connecting means 120 for performing attraction and detachment by a pair of magnets.
Through holes 19a and 19b similar to those described above are formed in the vertical frame 16 of the shoji 10 (10b) on the indoor side, and a resin holder 130 is mounted in the hollow portion 17 therebetween. The holder 130 is provided in the housing portion 1 that opens diagonally downward on the outdoor side.
32, a guide hole 134 communicating therewith and extending obliquely upward at the same angle toward the indoor side, and a guide strip 136 continuously extending toward the indoor side. And the through hole 1 on the indoor side
A flange 138 extending around 9a is screwed and fixed to the vertical frame 16. A magnet piece 122 constituting the connecting means 120 is slidably inserted into the housing part 132, and an oblique rod 124 connected to the indoor side surface thereof passes through the guide hole 134. A knob 12 serving as a weight at the lower end via a pin 125 is provided at an end of the rod 124 on the indoor side.
8 is rotatably connected.

On the other hand, an opening 23 is formed at a position facing the magnet piece 122 on the indoor side surface of the vertical frame 22 of the outdoor sliding door 20 (20b). This opening 23
The accommodation section 144 of the holder 142 screwed to the vertical frame 22 is inserted into the vertical frame 22. A magnet piece 140 constituting the connecting means 120 is inserted into the housing portion 144, and is fixed with an adhesive. Interior side surface 141 of this magnet piece 140
Is inclined at the same angle as the outdoor surface of the magnet piece 122,
The opposite magnetic poles are magnetized. In order to change the individual sliding state of each of the illustrated sliding doors 10 (10b) and 20 (20b) to the simultaneous sliding state, first, the knob 128 is lifted in the direction of the illustrated arrow, and the arm 126 is made linear with the rod 124. Next, when the knob 128 is pushed down toward the outside of the room, the arm 126 and the rod 124 are moved obliquely downward by being guided by the guide strip 136 and the guide hole 134, and the magnet piece 122 is also moved from the storage section 132 as shown in FIG. Extruded in the direction of the arrow. Then, the magnet piece 122 approaches the outdoor magnet piece 140, attracts each other, and makes surface contact. Note that the knob 128 is fixed to the arm 126 in advance so as to be deviated to the indoor side so as not to collide with the guide strip 136.

By pulling the knob 128 in the lateral direction in a state where the two magnet pieces 122 and 140 are attracted, the inner and outer shojis 1 are pulled.
0b and 20b can be slid simultaneously.
In this case, since the pin 125 is located in the guide hole 134, the operation of pulling in the lateral direction can be performed without rotating the arm 126. Conversely, in order to return to the individual slide state, the knob 128 is pulled obliquely upward toward the room against the magnetic force, and the arm 126 is rotated downward when the pin 125 is positioned closer to the room than the guide strip 136. Only needs to be done. In this case, the knob 128 also serving as the weight keeps the arm 126 in the vertical position, and can prevent the magnet piece 122 from accidentally jumping out of the accommodation portion 132 to the outside. Since these connecting means 100 and 120 use magnets, it is possible to connect and disconnect inner and outer sashes with a relatively simple mechanism and operation. The magnet pieces 102, 122
May be attached to the vertical frame 16 so as to be movable in the up-down direction, and can be attached to and detached from the plate piece 114 or the like so as to perform adsorption and detachment.

The present invention is not limited to the above embodiments. Although the connecting means 34 and 30 'shown in FIGS. 2 to 4 have one connecting piece 34, two connecting pieces 34 are provided in parallel above and below the handle 32, and two receiving pieces 24 are also mounted vertically. Alternatively, one receiving piece 24 may be provided with two receiving holes 26 at upper and lower positions. The handle 32 may be made into two parts, an inner part and an outer part, and a rotation and return mechanism may be provided internally so that the vertical grip part on the indoor side can be slightly inclined in the lateral direction in which the shoji is opened. The rack plate 5 of the connecting means 40 shown in FIG.

According to the double sash of the present invention described above, the inner and outer sashes facing each other can be slid simultaneously with a simple operation, and can be individually slid as appropriate. That is, while it is possible to obtain a closed state for heat insulation, soundproofing, and the like with a small amount of work, for example, in order to clean each part of the sash, each of the sliding doors can be easily slid individually. In addition, since the inner and outer sashes can be connected by engagement or the like, a lock such as a crescent only needs to be attached to the sash on the indoor side only, and the number of parts can be reduced. According to the fourth and fifth aspects of the present invention, the inner and outer sashes can be reliably engaged and disengaged by operating the handle from the indoor side. Further, according to the invention of claims 6 and 7, it is possible to obtain a double sash capable of performing a stable operation with a simple configuration in addition to the above.
