Description

Large opening sash

This invention relates to a sash, and more particularly to a large opening sash in which the size of the shoji is set larger than that of a general sash.

Large opening sashes excellent in viewability and designability have been put into practical use mainly in Europe (see Non-Patent Document 1), and are expected to spread in Asian regions including Japan in the future.
In the case of such a large opening sash, since the size of each shoji is large (for example, height 3,000 to 3,500 mm / width 2,000 to 2,500 mm), it also increases in weight compared to a general Japanese shoji (for example 250 Smooth opening and closing is difficult with a system that moves by rotating the door sliding door on the rail laid on the lower surface of the window frame.
For this reason, a so-called “solo van rail” system in which a door wheel is embedded in the lower surface of the window frame and a shoji is placed thereon is generally employed (see Patent Document 1).

1 and 2 are perspective views showing a basic structure of a large opening sash 10 according to the present invention, FIGS. 3 and 4 are longitudinal sectional views, and FIG. 5 is a transverse sectional view.
As illustrated, the large opening sash 10 includes an aluminum lower frame 11, an upper frame 12, and a four-sided frame 15 surrounded by a pair of vertical frames 13 and a vertical frame 14.

In addition, the four-way frame 15 is provided with an external motion shoddle 16 disposed on the outdoor side and an internal motion shoddy 17 disposed on the indoor side.
The external movement shodder 16 and the internal movement shoddy 17 include a pair glass 20 made of a pair of glasses 19 and 19 separated by a spacer 18 at a predetermined interval. Aluminum frames (front end frame, rear end frame, upper end frame, lower end frame) are mounted on the four sides of the pair glass 20.

The lower frame 11 is divided into an outdoor area and an indoor area by a central partition wall 30.
In addition, on the outdoor side and the indoor side in the lower frame 11, a plurality of door wheels 31 constituting the abacus rail are rotatably arranged (FIGS. 3 and 4).
An aluminum cover member 32 is covered on each door 31, and the upper end of the door 31 protrudes from the opening 33 provided in the cover 32.

The external sliding shovel 16 is placed on the door wheel 31 arranged outside the outdoor side, and the upper end thereof is inserted into the rail groove 36 between the outdoor side bulkhead 34 and the central bulkhead 35 of the upper frame 12, thereby external motion. The shoji 16 can be slid left and right (opening and closing direction).

The above configuration is generally common to the conventional large opening sash.
In the following, the features of the present invention will be described in comparison with a conventional large opening sash.

[1] Improvement of gap closing material As shown in FIGS. 6 and 7, in the case of the conventional large opening sash 100, the inner surface of the outdoor partition wall 102 of the lower frame 101, the outer surface and the inner surface of the central partition wall 103, A long gap closing material 105 made of mohair was disposed along the longitudinal direction of the lower frame 101 on the inner surface of the indoor partition wall 104.

This gap closing material 105 is similarly provided not only on the lower frame 101, but also on the inner surface of the outer partition wall of the upper frame, the outer and inner surfaces of the central partition wall of the upper frame, and the inner surface of the indoor partition wall of the upper frame ( (Not shown).
Moreover, it is similarly provided in the inner surface of the outdoor partition of each vertical frame, the outer surface and inner surface of the central partition of each vertical frame, and the inner surface of the indoor partition of each vertical frame (not shown).

Thus, by disposing the gap closing material 105 on the side of the four-sided frame, when the external movement obstacle 106 and the inner movement obstacle 107 are arranged at the closing position, the gap closing material 105 made of mohair on both sides of the peripheral edge thereof. Will come into contact, and contact with the outside air is restricted.
In addition, since each gap closing material 105 is made of mohair, resistance during opening and closing is minimized, and smooth movement of the external movement obstacle 106 and the internal movement obstacle 107 is ensured.
However, on the other hand, since all gap closing materials 105 are made of mohair, which is a fiber material, there is a problem that airtightness and watertightness are lacking. Then, it was also the cause of rain entering the room.

On the other hand, in the case of the large opening sash 10 according to the present invention, as shown in FIGS. 8 and 9, the inner surface of the outdoor partition wall 40 and the inner surface of the central partition wall 30 of the lower frame 11 are conventionally made of mohair. 1 is provided on the outer surface of the central partition wall 30 and the inner surface of the indoor side partition wall 42 of the lower frame 11, and a long rubber second gap closing material 43 is provided on the lower frame. 11 are arranged along the longitudinal direction.

Further, not only the lower frame 11 but also the outer surface of the central partition wall 35 of the upper frame 12 and the inner surface of the indoor partition wall 37 of the upper frame 12, instead of the conventional mohair, a second gap closing material 43 made of rubber is provided. It arrange | positions along the longitudinal direction of the upper frame 12 (refer FIG.3 and FIG.4).
On the other hand, a first gap closing material 41 made of mohair is disposed on the inner surface of the outdoor partition wall 34 and the inner surface of the central partition wall 35 of the upper frame 12.

Further, a second gap closing material 43 made of rubber is also disposed along the height direction of the vertical frame 13 on the inner surface of the indoor partition wall 85 of the vertical frame 13 (see FIG. 5).
On the other hand, a first gap closing material 41 made of mohair is disposed on the inner surface of the central partition wall 86 of the vertical frame 13.

Further, a second gap closing member 43 made of rubber is disposed along the height direction of the vertical frame 14 on the outer surface of the central partition wall 87 of the vertical frame 14 (see FIG. 5).
In contrast, a first gap closing material 41 made of mohair is disposed on the inner surface of the outdoor partition wall 88 of the vertical frame 14.

As shown in FIG. 10, the second gap plugging material 43 includes a pair of flexible contact pieces 44, and the tips of the contact pieces 44 are in close contact with the inner peripheral edge of the external movement shoji 16. At the same time, since it is closely attached to the inner peripheral edge of the internal movement shoji 17, high airtightness and watertightness can be exhibited.
The second gap closing material 43 is fixed by fitting the base end portion 45 into a concave groove 46 formed on the outer surface of the central partition wall 30 or the like.
Since the first gap closing material 41 made of mohair is provided on the outdoor side of each shoji, the sliding ability of the shoji is not impaired.

[2] Installation of water-stopping packing Conventionally, as shown in FIG. 7, no waterproofing measures have been taken in the gap 108 between the outdoor lower end of the internal movement shoji 107 and the lower frame 101 (central partition wall 103). In this structure, rain water hitting the outer surface of the internal movement shoji 107 easily enters the lower frame 101.
Rainwater that has entered into the lower frame 101 in this way is originally structured to be discharged to the outside from the drain 109 provided in the lower frame 101. However, if there is a lot of rainfall, The water is likely to be full, and there is a possibility that the overflowing water will flow into the room from the gap 110 between the lower end on the indoor side of the internal movement shoji 107 and the indoor side partition wall 104 of the lower frame 101.

On the other hand, in the case of the large opening sash 10 according to the present invention, as shown in FIG. 9, as shown in FIG. 9, a water-stop packing 50 for closing the gap 48 between the outdoor lower end of the internal motion shoji 17 and the lower frame 11 (central partition wall 30). Is installed.
The water-stop packing 50 is made of a rubber material having flexibility, and is disposed along the longitudinal direction of the lower end of the outer surface of the internal motion shoji 17 as shown in FIGS. 1 and 2.

As shown in FIG. 10, the water blocking packing 50 includes a flexible contact piece 51 having a J-shaped cross section, and the tip of the contact piece 51 is in close contact with the top surface of the central partition wall 30. Therefore, it is possible to effectively prevent rainwater from entering the lower frame 11 through the gap 48 between the central partition wall 30 and the lower end of the outer surface of the internal motion shoji 17.
The water-stopping packing 50 is fitted in a recessed groove 53 whose base end portion 52 is formed at the lower end of the outer surface of the internal stabiliser 17.

[3] Installation of an aluminum drainer Conventionally, as shown in FIG. 6, no waterproofing measures have been taken in the gap 111 between the lower end of the outer surface of the external sliding shovel 106 and the lower frame 101 (outdoor partition wall 102). In this structure, rainwater hitting the outer surface of the external sliding shovel 106 easily enters the lower frame 101.

On the other hand, in the case of the large opening sash 10 according to the present invention, as shown in FIG. 8, in order to prevent intrusion of rainwater from the gap 55 between the lower end of the outer surface of the external movement shoji 16 and the outdoor partition wall 40 of the lower frame 11, An aluminum drainer 56 is attached to the lower end of the outer surface of the external shoji 16.
The drainer 56 is provided with a bowl-shaped inclined surface 57. As shown in FIG. 1, the drainer 56 is arranged along the longitudinal direction of the lower end of the outer surface of the external sliding door 16 so that the inclined surface 57 covers the gap 55. It is installed. Therefore, it is possible to effectively prevent rainwater from entering the lower frame 11 from the gap 55 when the window is closed.

[4] Improvement of Lower Frame Receiving Material As shown in FIGS. 6 and 7, in the conventional large opening sash 100, a lower frame receiving material 112 for receiving the lower frame 101 is provided below the lower frame 101. It was.
The lower frame receiving material 112 is made of an aluminum extruded shape, and includes a bowl-shaped draining portion 113 for guiding rainwater discharged from the drain 109 of the lower frame 101 to the outside of the room.
Further, in order to prevent the outside air temperature from being transmitted into the room, a heat insulating material 114 made of polyamide is disposed at a position below the external movement shoji 106 and a position below the internal movement shoji 107, respectively.

Also in the case of the large opening sash 10 according to the present invention, as shown in FIGS. 8 and 9, a lower frame receiving material 60 for receiving the lower frame 11 is provided. However, as shown in FIG. Compared to the lower frame receiving material 112, the shape and structure have evolved and multifunctionalization has been achieved.

That is, this lower frame receiving material 60 is formed by integral molding by aluminum extrusion as in the conventional case, but a bowl-shaped drainage for guiding rainwater discharged from the drain 61 of the lower frame 11 to the outside. In addition to the portion 62, a barrier portion (rising portion) 63 for preventing water leaking from the lower frame 11 from entering the indoor side is provided.
The barrier portion 63 is formed so as to be parallel to the indoor partition wall 42 of the lower frame 11 with a certain gap therebetween. A backer material 68 and a sealing material 69 made of silicon are loaded between the barrier portion 63 and the indoor partition wall 42 of the lower frame 11.
For this reason, even when water in the lower frame 11 leaks, rainwater is blocked by the barrier portion 63 and the sealing material 69, so that it is possible to prevent water from entering the indoor side.

In addition, since a plurality of bolt storage portions 64 and bolt outlets 89 are provided, level adjustment when placing the large opening sash 10 on the window opening of the building by disposing the level adjustment bolt 65 here. Is possible.
Since the conventional lower frame receiving material 112 does not have such a bolt housing part or bolt outlet, it is necessary to connect a separate mounting frame material to attach the level adjustment bolt (not shown). This has led to an increase in the number of parts and a complicated work process.

In addition, a polyamide heat insulating material 66 is disposed in a double position at a position below the external movement shoji 16 and a position below the internal movement shoji 17 (see FIGS. 8 and 9).
Each heat insulating material 66 has a long belt shape, and is arranged along the longitudinal direction of the lower frame 11 by fitting both side ends thereof into engaging grooves 67 provided on the lower frame receiving material 60 side. It is fixed.
Thus, by arranging the pair of heat insulating materials 66 above and below with a certain gap therebetween, the heat insulating effect is improved as compared with the case where only one heat insulating material 114 is disposed, and the lower frame receiving material. 60 deformation can be suppressed.

[5] Improvement of the summoning part In the case of the foreign-made large opening sash 100, the protruding edge part of the summoning part where the rear end frame of the external movement shodder 106 overlaps with the rear end frame of the internal movement shoddy 107 is made of aluminum. There is a possibility that it is made of only the material and cannot sufficiently withstand wind pressure such as typhoon due to insufficient strength.
Therefore, conventionally, as shown in FIG. 12, the projecting edge 120 on the external movement shodder 106 side and the projecting edge 122 on the inner motion shoji 107 side are cut out, and a steel plate 124 is press-fitted into the inside, so that The device which raised rigidity was given.
For this reason, it was possible to increase the rigidity, but not only was it time-consuming to process, but the aesthetics were also impaired.

On the other hand, in the case of the large opening sash 10 according to the present invention, as shown in FIG. 13, the aluminum protruding edge portions 70, 71 provided at the summing portion of the external motion shoddle 16 and the internal motion shoji 17 are shown. A storage space 72 is provided in advance, and a structure in which a reinforcing steel plate 73 is stored therein is provided. The upper end of the storage space 72 is covered with an aluminum lid (not shown).
As a result, the required rigidity can be ensured without impairing the aesthetic appearance, and it is possible to sufficiently withstand wind pressure such as a typhoon.

[6] Improving the arrangement of the heat insulating material provided in the door-to-door portion of the shoji When opening and closing the sash, it is usually necessary to use the door-end handle shape material in the vicinity of the door-to-door portion of the external or internal moving shoji. It is done by pulling in the required direction, but in the case of a large opening sash, the weight of the shoji itself is heavy, so that a large load is applied to the joint between the door-end handle and the pair of glass tip frames. Become.

FIG. 14 shows the door stop portion of the external sliding door 106 in the conventional large opening sash 100. As shown in the figure, the front end engaging portion 131 of the outdoor door-end handle shape 130 and the indoor side door-end handle shape material are shown. 132 is connected to the front end engaging portion 133 by a single heat insulating material 134, and a pair of glass 135 (a pair of glass 136, a pair of glass 136, 136), the surface of the tip frame 137 is sandwiched. The front end frame 137 of the pair glass 135, the outdoor door-end handle material 130, and the indoor-side door handle material 132 are fixed by adhesion.
Although illustration is omitted, the door stop portion of the internal motion shoji 107 has a similar structure.

As described above, since there is conventionally only one heat insulating material 134 connecting the front end engaging portion 131 of the outdoor side door-end handle shape member 130 and the front end engaging portion 133 of the indoor side door-end handle shape member 132, If a large force in the closing direction is applied to either the door-end handle shape material 130 or the indoor side door-end handle shape material 132, the door-end handle shape material easily opens outward, and as a result, peels off from the front end frame 137 of the pair glass 135. There was a risk of falling.

On the other hand, in the case of the large opening sash 10 according to the present invention, as shown in FIG. 15, the distal end engaging portion 76 of the outdoor door handle shape member 75 and the indoor side door handle shape member 77 of the external sliding door 16. Are connected by two heat insulating materials 79 and 80 made of polyamide.
Each of the heat insulating materials 79 and 80 has a long belt shape, and both ends of the heat insulating materials 79 and 80 are fitted into the engaging grooves provided on the side of the front end engaging portion 76 and the front end engaging portion 78, so Arranged and fixed along 16 height directions.
The vicinity of the door stop portion of the internal motion shoji 17 has a similar structure (see FIG. 5).
Reference numeral 81 in the figure indicates door-to-door rubber.

In this way, a pair of heat insulating materials 79, 80 are arranged with a certain gap between each other, and thereby, the front end engaging portion 76 of the outdoor doorside handle shape material 75 of the external movement shoji 16 and the indoor side doorside handle shape material. 77 is connected to the front end engaging portion 78, so that even if a large force in the closing direction is applied to either the outdoor door handle shape material 75 or the indoor door handle shape material 77, the door It becomes difficult for the front handle material to be opened outward, and there is no risk that the outdoor door handle material 75 and the indoor door handle material 77 are peeled off from the front end frame 82 of the pair glass 20.
Further, the heat insulating effect can be further improved by arranging the pair of heat insulating materials 79 and 80 with a certain gap therebetween.

In the above, the large opening sash 10 provided with the external movement shoji 16 and the internal movement shoji 17 has been exemplified, but the present invention is not limited to this, and one or three or more shojis in a four-sided frame. It can be widely applied to a large opening sash that installs.
When three or more shoji screens are installed, a plurality of internal partition walls are formed in the lower frame and the upper frame, and the lower frame and the upper frame are partitioned into three or more regions. And each area | region in a lower frame will arrange | position the door roller and cover material only for each shoji.

Further, as described above, the present invention is suitable for a so-called large opening sash in which the size of the shoji is larger than that of a general sash shoji, but there is no clear standard for whether or not it is large. There is no need to limit its size.
In short, it can be widely applied to a sash van rail sash with a door frame embedded in the lower frame.
In addition, the “door wheel” includes a spherical ball bearing that is rotatably mounted in the lower frame.

The large opening sash 10 is also provided on the side of the four-sided frame 15 including the lower frame 11, the upper frame 12, the vertical frame 13, and the vertical frame 14, as shown in FIGS. 3 to 5, 8, 9, and 15. Since a heat insulating material 90 and a flange 91 made of a pair of polyamides and the like are disposed along the respective longitudinal directions and a certain distance is secured between them, a high heat insulating effect can be exhibited.

In the above case, both of the heat insulating materials 90 and 91 disposed in each frame have the same curved shape, and the respective concave portions are disposed so as to face each other. Is not limited to this.
For example, as shown in FIGS. 16 to 21, one of the heat insulating materials (the heat insulating material 91 located outside in the drawings) may be constituted by a flat plate-shaped heat insulating material 92 having no curvature. Although illustration is omitted, both of them can be constituted by a flat plate-like heat insulating material.

In the large opening sash 10 shown in FIGS. 3, 4, and 8 to 10, each door 31 is rotatably supported by an individual shaft 93 and a bearing 94. The present invention is not limited to the construction of such a door cart.

For example, as shown in FIGS. 16 to 19, one common shaft 95 is inserted through two door wheels 31 and ridges 31 arranged on the left and right sides, and this is rotatably supported by a common bearing 96. It may be configured. As a result, simplification of the configuration and smoothing when moving the shoji are possible.
