Description

Large opening window frame

The present invention relates to a window frame, and more particularly to a large opening window frame in which the size of the sliding window is set to be larger than a general window frame.

In the future, it is expected that the large-opening window frame, which is excellent in the design and the design, will be put into practical use (see Non-Patent Document 1). In the case of such a large opening window frame, since each sliding window has a large size (for example, a height of 3,000 to 3,500 mm/width of 2,000 to 2,500 mm), the weight is also higher than that of a Japanese sliding window (for example, 250~) 400Kg), it is difficult to perform smooth opening and closing by rotating the sash pulley on the side of the sliding window on the guide rail laid under the window frame. Therefore, the so-called "arbitrary guide rail" method (see Patent Document 1) has been generally used, in which a sash pulley is embedded under the window frame, and a sliding window is placed thereon.

As shown in the figure, the large opening sash 10 is provided with a square frame 15 surrounded by an aluminum lower frame 11, an upper frame 12, and a pair of stiles 13 and stiles 14.

Further, the square frame 15 is provided with an outer side sliding sliding window 16 disposed on the outdoor side and a sliding sliding window 17 disposed on the inner side of the indoor side. The outer side moving sliding window 16 and the inner side moving sliding window 17 are provided with a double glazing unit 20 which is formed by a pair of glass 19 and 19 which are separated by a spacer 18 at a predetermined interval. A frame made of aluminum (front end (window against the wall) frame, rear end frame, upper end frame, lower end frame) is attached to the four sides of the double glazing unit 20.

The lower frame 11 is partitioned into an outdoor side area and an indoor side area by the central partition wall 30. Further, a plurality of sash pulleys 31 (FIGS. 3 and 4) constituting the abazon type guide rail are rotatably disposed on the outdoor side and the indoor side in the lower frame 11. Each of the sash pulleys 31 is covered with an aluminum cover member 32, and the upper end portion of the sash pulley 31 protrudes from the opening portion 33 provided in the cover member 32.

The outer side moving sliding window 16 is a rail groove 36 which is placed between the outdoor side partition wall 34 of the upper frame 12 and the center partition wall 35 by moving the sliding window 16 on the outside of the sash pulley 31 disposed on the outdoor side. , and can slide to the left and right (opening and closing direction). Further, the inner side moving sliding window 17 is placed on the sash pulley 31 disposed on the indoor side, and the sliding window 17 is moved inside, and the upper end is inserted into the upper frame 12 The rail groove 38 between the inner partition wall 37 and the center partition wall 35 is slidable in the left and right (opening and closing directions).

The above configuration is substantially the same as the conventional large opening window frame. In the following description, the features of the present invention will be described while being compared with a conventional large opening window frame.

[1] Improvement of gap filler

As shown in FIG. 6 and FIG. 7, in the case of the conventional large opening sash 100, the inner surface of the outdoor side partition 102 of the lower frame 101, the outer surface and the inner surface of the central partition 103, and the interior of the lower frame 101 are shown. On the inner surface of the side partition wall 104, a long-sized gap filler 105 composed of Angora wool is disposed along the longitudinal direction of the lower frame 101.

The gap filler 105 is provided not only on the lower frame 101 but also on the inner surface of the outdoor side partition wall of the upper frame, the outer surface and the inner surface of the central partition of the upper frame, and the inner surface of the indoor side partition of the upper frame. (The illustration is omitted). Further, it is also provided on the inner surface of the outdoor side partition wall of each mullion, the outer surface and the inner surface of the center partition of each mullion, and the inner surface (not shown) of the indoor side partition of each mullion.

In this manner, when the gap filler 105 is disposed on the side of the square frame, when the outer side sliding sliding window 106 and the inner side moving sliding window 107 are disposed at the closed position, the gap filler 105 made of Angora wool can be brought into contact with the gap filler 105. The outer side moves the sliding window 106 and the inner side of the outer side of the sliding window 107 to restrict contact with the outside air. Further, since each of the gap fillers 105 is made of Angora wool, the resistance during opening and closing is also minimized, and the smooth movement of the outer moving sliding window 106 and the inner moving sliding window 107 can be ensured. But on the other hand, since all the gap fillers 105 are made of fiber The Angolan wool of the Uyghur material is a problem, so there is a problem of lack of airtightness and watertightness. In fact, in Japan, where the annual rainfall is high, the problem has become a cause of rainwater intrusion into the room.

On the other hand, in the case of the large opening sash 10 of the present invention, as shown in FIGS. 8 and 9, the inner surface of the outdoor side partition 40 of the lower frame 11 and the inner surface of the central partition 30 are provided. The first gap filler 41 composed of Angolan wool is similar to the conventional one, but the outer surface of the central partition 30 and the inner surface of the indoor partition 42 of the lower frame 11 are along the longitudinal direction of the lower frame 11. A second gap filler 43 made of long rubber is provided.

Further, not only in the lower frame 11, but also on the outer surface of the center partition 35 of the upper frame 12 and the inner surface of the indoor side partition wall 37 of the upper frame 12, the long side of the upper frame 12 is disposed instead of the conventional Angora wool. There is a rubber second gap filler 43 (see FIGS. 3 and 4). On the other hand, the first gap filler 41 made of Angora wool is disposed on the inner surface of the outdoor side partition wall 34 of the upper frame 12 and the inner surface of the center partition wall 35.

Further, a second gap filler 43 made of rubber is placed on the inner surface of the indoor side partition 85 of the mullion 13 along the height direction of the stile 13 (see FIG. 5). On the other hand, the first gap filler 41 made of Angora wool is disposed on the inner surface of the center partition 86 of the mullion 13 .

Further, a second gap filler 43 made of rubber is placed on the outer surface of the center partition 87 of the stile 14 along the height direction of the stile 14 (see FIG. 5). On the other hand, the first gap filler 41 made of Angora wool is disposed on the inner surface of the outdoor side partition 88 of the mullion 14.

As shown in FIG. 10, the second gap filler 43 is provided with a The contact piece 44 of the pair of flexible pieces is provided, and the front end of each contact piece 44 is in close contact with the outer peripheral edge of the outer side sliding sliding window 16 and is closely attached to the inner side of the inner surface of the sliding window 17 so as to be able to play a higher position. Air tightness and water tightness. The second gap filler 43 is fixed by fitting the base end portion 45 into the recess 46 formed on the outer surface or the like of the center partition wall 30. Further, since the first gap filler 41 composed of Angolan wool is disposed on the outdoor side of each of the sliding windows, the sliding property of the sliding window is not impaired.

[2] setting of water stop liner

Conventionally, as shown in FIG. 7, since no waterproof countermeasure is applied to the gap 108 between the outdoor side lower end of the inner side sliding sliding window 107 and the lower frame 101 (the center partition wall 103), the outer surface of the sliding window 107 is moved inside. The rainwater easily penetrates into the structure in the lower frame 101. In this way, the rainwater that has penetrated into the lower frame 101 is originally configured to be discharged to the outside from the drain port 109 provided in the lower frame 101. However, when there is a lot of rainfall, the lower frame 101 is easy. When it is full, the overflowed water may flow from the inside to the inside of the gap between the lower end of the indoor side of the sliding window 107 and the indoor side partition 104 of the lower frame 101.

On the other hand, in the case of the large opening sash 10 of the present invention, as shown in FIG. 9, a gap 48 for blocking the outdoor side lower end of the inner side sliding sliding window 17 and the lower frame 11 (the center partition wall 30) is provided. Water pad 50. The water stop liner 50 is made of a flexible rubber material, and is disposed along the longitudinal direction of the lower end of the outer surface of the sliding window 17 as shown in FIGS. 1 and 2 .

As shown in FIG. 10, the water stop liner 50 is provided with a contact piece 51 having a flexible J-shaped cross section, and the front end of the contact piece 51 is closely attached to the center partition. The top surface of the wall 30 can effectively prevent rainwater from penetrating into the lower frame 11 from the gap 48 between the central partition wall 30 and the lower end of the outer surface of the inner side sliding sliding window 17. The water stop pad 50 has a base end portion 52 fitted in a recess 53 formed at the lower end of the outer surface of the inner side sliding sliding window 17.

[3]Setting of aluminum flashing board

Conventionally, as shown in FIG. 6, since no countermeasure against water is applied to the gap 111 between the lower end of the outer surface of the sliding window 106 and the lower frame 101 (outdoor side partition 102), the sliding window 106 is moved outside. The rainwater on the surface easily penetrates into the structure in the lower frame 101.

On the other hand, in the case of the large opening sash 10 of the present invention, as shown in FIG. 8, in order to prevent rainwater from penetrating from the outside, the gap 55 between the lower end of the outer surface of the sliding window 16 and the outdoor side partition 40 of the lower frame 11 is infiltrated. An aluminum flashing 56 is attached to the lower end of the outer surface of the sliding window 16 on the outer side. The flashing plate 56 is provided with an eaves-like inclined surface 57. As shown in FIG. 1, the inclined surface 57 is configured to cover the longitudinal direction of the outer surface of the outer surface of the sliding window 16 so as to cover the gap 55. Assume. Therefore, when the window is closed, it is possible to effectively prevent the rainwater from penetrating into the lower frame 11 from the above-mentioned gap 55.

[4] Improvement of lower frame support member

As shown in FIGS. 6 and 7, in the conventional large opening window frame 100, the lower frame support member 112 for supporting the lower frame 101 is provided below the lower frame 101. The lower frame supporting member 112 is made of an aluminum profile, and has a rainproof portion 113 for guiding the rainwater discharged from the drain port 109 of the lower frame 101 to the outdoor. Also, in order to prevent outside The temperature of the part is transmitted to the room, and the heat insulating material 114 made of polyimide is disposed at a position below the outer side sliding sliding window 106 and below the inner side moving sliding window 107.

In the case of the large opening sash 10 of the present invention, as shown in FIGS. 8 and 9, although the frame supporting member 60 for supporting the lower frame 11 is provided, as shown in FIG. 11, compared with the conventional one. The lower frame supporting member 112 has a more evolved shape and structure and can be multi-functionalized.

That is, the lower frame supporting member 60 is the same as the conventional one, and is formed by one-piece forming by aluminum extrusion, except for the rainwater which is discharged to the outside from the drain port 61 of the lower frame 11. In addition to the rain-proof portion 62, a barrier portion (standing portion) 63 for preventing the water leaking from the lower frame 11 from infiltrating into the indoor side is provided. The barrier portion 63 is formed to be parallel to the indoor side partition wall 42 of the lower frame 11 with a constant gap therebetween. Further, between the barrier portion 63 and the indoor side partition wall 42 of the lower frame 11, a sealing material 69 made of a support 68 and silicone is loaded. Therefore, even in the case where the water in the lower frame 11 leaks, since the rainwater is blocked by the barrier portion 63 and the sealing material 69, it is possible to prevent the water from seeping to the indoor side.

Further, since the plurality of bolt accommodating portions 64 and the bolt outlets 89 are provided, the horizontal adjustment bolts 65 are disposed there, and the horizontal adjustment of the large opening sash 10 when placed in the window opening of the building can be performed. . Since the frame supporting member 112 does not have the above-described bolt accommodating portion or bolt outlet, it is necessary to connect another mounting frame material (not shown) in order to attach the horizontal adjusting bolt, thereby causing an increase in the number of parts and work steps. The complexity.

Further, the heat-insulating material 66 made of polyamide is placed in two layers at a position below the sliding window 16 and a position below the sliding window 17 (see FIGS. 8 and 9). Each of the heat insulating materials 66 is in the form of a long strip by using both sides thereof The engagement groove 67 fitted to the side of the lower frame support member 60 is fitted and fixed along the longitudinal direction of the lower frame 11. In this manner, by disposing the pair of heat insulating materials 66 on the upper and lower sides with a certain gap therebetween, the heat insulating effect can be improved and the lower frame supporting member 60 can be suppressed as compared with the case where only one insulating material 114 is disposed. Deformation.

[5] Improvement of the rear end frame overlap

In the case of the large opening sash 100 manufactured in a country other than Japan, the outer end of the sliding window 106 and the inner side of the sliding window 107 are rearwardly overlapped, and the end frame overlaps the protruding edge of the end frame overlapping portion, since only the aluminum material is respectively Since it is formed and the strength is insufficient, there is a possibility that the wind pressure such as a typhoon cannot be sufficiently withstood. Therefore, as shown in FIG. 12, it is conventionally that the steel plate 124 is pressed into the inside by the opening edge portion 120 on the side of the outer sliding sliding window 106 side and the protruding edge portion 122 on the side of the inner sliding sliding window 107. The rigidity of the end frame overlap. Therefore, although the rigidity can be improved, it results in not only the labor of the processing but also the aesthetic appearance.

On the other hand, in the case of the large opening sash 10 of the present invention, as shown in FIG. 13, there is provided an aluminum protrusion which is provided at the outer side moving sliding window 16 and the inner side moving sliding window 17 after the end frame overlapping portion. The edge portions 70 and 71 are provided with a housing space 72 in advance, and a structure for reinforcing the steel sheet 73 is housed therein. At the upper end of the accommodating space 72, a cover member made of aluminum (not shown) is covered. As a result, the rigidity can be ensured without impairing the appearance, and the wind pressure such as a typhoon can be sufficiently withstood.

[6] Improvement of the arrangement of the heat insulating material placed on the front end of the sliding window

When opening and closing the window frame, the window end handle is usually touched by the hand near the head before the hand is placed on the outer side to move the sliding window or the inner side to move the sliding window. The profile is pulled in the desired direction, but in the case of a large open window frame, since the weight of the sliding window itself is quite heavy, the window end handle profile and the double-glazed front end frame are joined. Part of the application of a large load.

Figure 14 shows the outer end of the conventional large opening sash 100 moving the sliding window 106 before the end frame hits the head, as shown, the outdoor side window against the wall end handle profile 130 front end engagement portion 131 and the indoor side window against the wall end handle The front end engaging portion 133 of the profile 132 is joined by a piece of heat insulating material 134 to form a double glazing 135 (a pair of glass 136, 136). The surface of the front end frame 137 is opposed to the wall by the outdoor side window. The end handle profile 130 and the interior side window are sandwiched by the wall end handle profile 132. The double-glazed 135 front end frame 137 and the outdoor side window against the wall end handle profile 130 and the indoor side window against the wall end handle profile 132 are fixed by adhesion. Although not shown in the drawings, the inner end sliding sliding window 107 has the same structure as the front end frame facing head.

Thus, since it is conventional to connect the outdoor side window to the heat insulating material 134 between the front end engaging portion 131 of the wall end handle profile 130 and the front end engaging portion 133 of the indoor side window against the wall end handle profile 132, only one piece is The outdoor side window exerts a large force in the closing direction by either the wall end handle profile 130 and the indoor side window against the wall end handle profile 132, and the window end handle profile is easily turned outward toward the wall, and as a result, there is There is a risk of peeling off from the front end frame 137 of the double glazing 135.

In contrast, in the case of the large opening sash 10 of the present invention, as shown in FIG. 15, the outdoor side window of the outer side sliding sliding window 16 is adjacent to the wall end handle profile 75 front end engaging portion 76 and the indoor side window against the wall The end handle profiles 77 are joined between the front end engaging portions 78 by two sheets of heat insulating materials 79 and 80 made of polyamide. Each of the heat insulating materials 79 and 80 has a long strip shape, and is slid along the outer side by fitting both side ends thereof to the engaging grooves provided on the side of the front end engaging portion 76 and the front end engaging portion 78. The window 16 is disposed in the height direction and fixed. The front end frame of the inner side sliding sliding window 17 is also in the vicinity of the head, and has the same structure (see FIG. 5). The symbol 81 in the figure indicates the rubber for the sash.

In this manner, the pair of insulating materials 79 and 80 are disposed with a gap therebetween, and the outer side of the sliding window 16 is moved outward by the insulating material to the front end of the wall end handle profile 75. 76 is connected between the indoor side window wall end handle profile 77 front end engagement portion 78, so that even the outdoor side window against the wall end handle profile 75 and the indoor side window against the wall end handle profile 77 are applied in the closing direction. The greater force, the window end handle profile is also not easy to open to the outside, without the outdoor side window against the wall end handle profile 75 or the indoor side window against the wall end handle profile 77 from the front end of the double glazing 20 Box 82 is at risk of peeling off. Further, by arranging the pair of heat insulating materials 79 and 80 with a constant gap therebetween, the heat insulating effect can be further improved.

In the above description, the large opening sash 10 including the outer side sliding sliding window 16 and the inner side moving sliding window 17 is exemplified, but the present invention is not limited thereto, and can be widely applied to one piece in the square frame. Or a large opening window frame with more than 3 sliding windows. When three or more sliding windows are provided, 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. Further, in each of the regions in the lower frame, a sash pulley and a cover for each sliding window are disposed.

Further, as described above, the present invention is suitable for a so-called large-open window frame in which the size of the sliding window is larger than that of a normal window frame, but there is no clear reference for whether it is large or not. The necessity of size. In short, it can be widely applied to a window frame of an abacus rail type in which a sash pulley is buried in a lower frame. Further, the "sash pulley" also includes a spherical ball bearing that is rotatably attached to the lower frame.
