Description

Large opening window frame

The present invention relates to a window frame, and more particularly to a large-opening window frame with a sliding window set to be larger than a general window frame.

Large open window frames with excellent visibility and design centered on Europe have been put into practical use (see Non-Patent Document 1), and it is expected that they will gradually spread to Asian regions including Japan. 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 ~ 3,500mm / width of 2,000 ~ 2,500mm), the weight is also higher than that of a general sliding window in Japan (for example, 250 ~ 400Kg), it is difficult to open and close smoothly by rotating the window frame pulley on the sliding window side and laying it on the guide rail under the window frame. Therefore, the so-called "abacus guide" method (see Patent Document 1) is generally used, in which a window frame pulley is embedded under the window frame and a sliding window is placed thereon.

The guide groove 38 between the inner partition wall 37 and the central partition wall 35 is slidable to the left and right (opening and closing directions).

The above structure is substantially the same as the conventional large-opening window frame. In the following description, a characteristic point of the present invention will be described in comparison with a conventional large open window frame.

[1] Improvement of gap filler

As shown in FIGS. 6 and 7, in the case of the conventional large opening window frame 100, the inner surface of the outdoor side partition wall 102 of the lower frame 101, the outer surface and inner surface of the central partition wall 103, and the interior of the lower frame 101 The inner surface of the side partition wall 104 is respectively provided with a gap filler 105 made of angora wool along the long side direction of the lower frame 101.

This gap-filling material 105 is provided not only on the lower frame 101 but also on the inner surface of the outdoor side partition of the upper frame, the outer and inner surfaces of the central partition of the upper frame, and the inner surface of the indoor side partition of the upper frame. (Illustration omitted). Also, they are also provided on the inner surface of the outdoor side partition wall of each mullion, the outer surface and inner surface of the center partition wall of each mullion, and the inner surface of the indoor side partition wall of each mullion (not shown).

In this way, because the gap filling material 105 is arranged on the side of the square frame, when the outer moving sliding window 106 and the inner moving sliding window 107 are arranged in the closed position, the gap filling material 105 made of angora wool can abut against Both sides of the peripheral edges of the outer moving sliding window 106 and the inner moving sliding window 107 restrict contact with the outside air. In addition, since each gap filler 105 is made of angora wool, the resistance during opening and closing is also minimal, and smooth movement of the outer moving sliding window 106 and the inner moving sliding window 107 can be ensured. On the other hand, since all gap fillers 105 are made of fibers The Uyghur material is made of Angora wool, so there is a problem of lack of air tightness and water tightness. In fact, as in Japan, in areas with high annual rainfall, this problem has become the cause of rainwater intrusion into the room.

In contrast, in the case of the large-open window frame 10 of the present invention, as shown in FIGS. 8 and 9, the inner surface of the outdoor side partition wall 40 and the inner surface of the central partition wall 30 of the lower frame 11 are provided with The first gap filler 41 made of Angora wool is the same as the conventional one, but the outer surface of the central partition wall 30 and the inner surface of the indoor partition wall 42 of the lower frame 11 are along the long side of the lower frame A second gap filler 43 made of long rubber is arranged.

In addition, 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 are arranged along the long side of the upper frame 12 instead of the conventional Angora goat wool. There is a second gap filler 43 made of rubber (see FIGS. 3 and 4). In contrast, a first gap filler 41 made of angora wool is arranged on the inner surface of the outdoor side partition wall 34 and the inner surface of the center partition wall 35 of the upper frame 12.

A second gap filler 43 made of rubber is also arranged on the inner surface of the indoor-side partition wall 85 of the mullion frame 13 along the height direction of the mullion frame 13 (see FIG. 5). On the other hand, a first gap filler 41 made of angora wool is arranged on the inner surface of the central partition wall 86 of the mullion 13.

A second gap filler 43 made of rubber is arranged on the outer surface of the center partition wall 87 of the mullion frame 14 along the height direction of the mullion frame 14 (see FIG. 5). In contrast, a first gap filler 41 made of angora wool is arranged on the inner surface of the outdoor-side partition wall 88 of the mullion 14.

As shown in FIG. 10, the second gap filler 43 is One pair of contact pieces 44 is provided. The front end of each contact piece 44 is in close contact with the peripheral edge of the inner surface of the outer mobile sliding window 16 and is in close contact with the peripheral edge of the inner surface of the inner mobile sliding window 17. Air tightness and water tightness. The second gap-filling material 43 is fixed by fitting its base end portion 45 into a groove 46 formed on the outer surface of the center partition wall 30 or the like. In addition, since the first gap filler 41 made of Angora wool is arranged on the outdoor side of each sliding window, the sliding properties of the sliding window are not impaired.

[2] Setting of water stop pad

As shown in FIG. 7, since no waterproof measures are implemented for the gap 108 between the lower end of the outdoor side of the inner moving sliding window 107 and the lower frame 101 (central partition 103), it is hit on the outer surface of the inner moving sliding window 107. The rainwater easily penetrates into the structure of the lower frame 101. In this way, although the rainwater that has penetrated into the lower frame 101 was originally configured to be discharged from the drainage port 109 provided in the lower frame 101 to the outdoors, there are cases where there is a lot of rainfall, and it is easy to enter the lower frame 101 It may become full, and the overflowed water may flow into the room from the gap 110 between the lower end of the indoor side of the sliding window 107 and the indoor partition wall 104 of the lower frame 101.

In contrast, in the case of the large-opening window frame 10 of the present invention, as shown in FIG. 9, a stop 48 is provided to block the gap between the lower end of the outdoor side of the sliding window 17 inside and the lower frame 11 (the central partition 30). Water cushion 50. The water-stop pad 50 is made of a flexible rubber material, and as shown in FIG. 1 and FIG. 2, it is disposed along the longitudinal direction of the lower end of the outer surface of the sliding window 17 that moves inside.

As shown in FIG. 10, the water-stop pad 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 in close contact with the central 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 moving sliding window 17. A base end portion 52 of the water-stop pad 50 is fitted into a groove 53 formed on the lower end of the outer surface of the inner sliding window 17.

[3] Setting of aluminum rain shield

As shown in FIG. 6, since no waterproof measures are implemented for the gap 111 between the lower end of the outer surface of the outer moving sliding window 106 and the lower frame 101 (outdoor side partition 102), it is outside the outer moving sliding window 106. The rain on the surface easily penetrates into the structure in the lower frame 101.

In contrast, in the case of the large-open window frame 10 of the present invention, as shown in FIG. 8, in order to prevent rainwater from infiltrating into the gap 55 of the outer surface lower end of the sliding window 16 from the outside and the outdoor side partition wall 40 of the lower frame 11, An aluminum rain shield 56 is mounted on the lower end of the outer surface of the outer sliding window 16. The rain shield 56 is provided with an eave-shaped inclined surface 57. As shown in FIG. 1, the inclined surface 57 covers the gap 55 and moves along the long side of the lower end of the outer surface of the sliding window 16. Assume. Therefore, when the window is closed, rainwater can be effectively prevented from penetrating into the lower frame 11 from the gap 55.

[4] Improvement of lower frame supporting members

As shown in FIGS. 6 and 7, in the conventional large-open window frame 100, a support member 112 for supporting the lower frame 101 of the lower frame 101 is provided below the lower frame 101. The lower frame support member 112 is made of an aluminum profile, and includes a rainproof portion 113 for guiding rainwater discharged from the drainage port 109 of the lower frame 101 to an outdoor eaves-like shape. Also, to prevent outside The partial air temperature is transmitted to the room, and a thermal insulation material 114 made of polyamide is disposed below the position of the outer movable sliding window 106 and the position of the inner movable sliding window 107 below.

In the case of the large-open window frame 10 of the present invention, as shown in FIGS. 8 and 9, although a lower frame supporting member 60 is also provided to support the lower frame 11, as shown in FIG. 11, compared with the conventional one The lower frame support member 112 is more evolved in shape and structure, and can be multifunctional.

That is, the lower frame support member 60 is the same as the conventional one, and although it is formed by forming a single body by extruding aluminum, except for the eaves for guiding the rainwater discharged from the lower frame 11 to the outside In addition to the shape of the rainproof portion 62, a barrier portion (upright portion) 63 is provided to prevent water leaking from the lower frame 11 from penetrating into the indoor side. The barrier wall portion 63 is formed so as to be parallel to the indoor-side partition wall 42 of the lower frame 11 with a certain gap therebetween. Further, a sealing material 69 made of a support 68 and silicone is filled between the barrier wall portion 63 and the indoor-side partition wall 42 of the lower frame 11. Therefore, even in the case where water leaks in the lower frame 11, rainwater is blocked by the barrier portion 63 and the sealing material 69, so that it is possible to prevent water from leaking to the indoor side.

In addition, since a plurality of bolt accommodating portions 64 and bolt guide openings 89 are provided, the horizontal adjustment bolts 65 are arranged there, so that the level adjustment when the large opening window frame 10 is placed on the window opening portion of the building can be performed. . The conventional frame supporting member 112 does not have the above-mentioned bolt accommodating portion or bolt lead-out. Therefore, in order to attach the horizontal adjustment bolt, it is necessary to connect another mounting frame material (not shown), which results in an increase in the number of parts and operation steps. Complication.

In addition, a polyimide heat-insulating material 66 is arranged in two layers at a position below the outer moving sliding window 16 and a position below the inner moving sliding window 17 (see FIGS. 8 and 9). Each heat-insulating material 66 has a long strip shape. The engaging groove 67 provided on the lower frame supporting member 60 side is arranged and fixed along the longitudinal direction of the lower frame 11. In this way, by arranging a pair of heat insulation materials 66 above and below each other with a certain gap, the heat insulation effect can be improved compared with the case where only one piece of heat insulation material 114 is disposed, and the lower frame support member 60 can be suppressed. Deformation.

[5] Improvement of rear frame overlap

In the case of a large-open window frame 100 manufactured in a country other than Japan, the end frame behind the sliding window 106 on the outside and the end frame overlapping on the sliding window 107 on the inside will overlap the protruding edges of the overlapping portion of the rear frame, because they are made of aluminum only. It has insufficient strength, so there is a possibility that it cannot fully withstand the wind pressure of typhoons and the like. Therefore, as shown in FIG. 12, the conventional method is to open the protruding edge portion 120 on the outer movable sliding window 106 side and the protruding edge portion 122 on the inner movable sliding window 107 side, and press the steel plate 124 into the interior to improve The rigidity of the overlap of the end frames. Therefore, although it is possible to improve rigidity, it not only results in processing time, but also damages the appearance.

In contrast, in the case of the large-opening window frame 10 of the present invention, as shown in FIG. 13, an aluminum protrusion provided with an overlapping portion of the end frame after the outer moving sliding window 16 and the inner moving sliding window 17 is provided. The edges 70 and 71 have a structure in which a storage space 72 is provided in advance, and a steel plate 73 for reinforcement is stored in the storage space 72. An upper end of the storage space 72 is covered with an aluminum cover (not shown). As a result, the necessary rigidity can be ensured without impairing the appearance, and the wind pressure such as a typhoon can be fully withstood.

[6] Improved the configuration of the heat-insulating material placed on the front frame before the sliding window

When opening and closing the window frame, it is common to place the hand on the side of the window near the head before the end frame touches the wall handle placed on the outside mobile sliding window or the inside mobile sliding window. On the profile and pull it in the required direction, but in the case of a large opening window frame, because the weight of the sliding window itself is quite heavy, the handle profile on the wall side of the window and the front end frame of the double glass Partly applied a large load.

FIG. 14 shows the conventional large opening window frame 100 outside the sliding window 106 before the front end frame touches the head. As shown in the figure, the front side engaging section 131 of the outdoor side window near the wall 130 and the indoor side window near the wall The front end engaging portion 133 of the profile 132 is connected by a single piece of heat insulating material 134, and the surface of the front end frame 137 of the double glass 135 (a pair of glasses 136, 136) is leaned against the wall by the outdoor side window The end handle profile 130 and the indoor side window are held by the wall end handle profile 132. The front end frame 137 of the double-glazed glass 135 and the wall-side handle profile 130 for outdoor windows and the wall-side handle profile 132 for indoor windows are fixed by adhesion. Although not shown, the front frame of the inner moving sliding window 107 also has the same structure as the head.

In this way, since there is only one piece of heat insulation material 134 connected between the front end engaging portion 131 of the wall side handle profile 130 of the outdoor window and the front end engaging portion 133 of the wall side handle profile 132 of the indoor side window, Any one of the outdoor side wall-side handle profile 130 and the indoor side wall-side handle profile 132 exerts a large force in the closing direction, and the window-side wall handle profile is easy to open outward. As a result, there is There is a danger that the end frame 137 may peel off from the front of the double-glazed glass 135.

On the other hand, in the case of the large-open window frame 10 of the present invention, as shown in FIG. 15, the front side engaging section 76 of the outdoor side window profile 75 on the side of the outdoor side sliding window 16 moves against the wall on the side of the indoor side window The end handle profile 77 is connected between the front end engaging portions 78 by two pieces 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 the both ends of the heat-insulating materials 79 and 80 to the engaging grooves provided on the front-end engaging portion 76 and the front-end engaging portion 78 sides. The window 16 is arranged and fixed in the height direction. The inner moving sliding window 17 has the same structure as the front frame near the head (see FIG. 5). Reference numeral 81 in the figure indicates rubber for window frame contact.
