Description

  The present invention relates to a sash that is attached to an opening of a building frame and houses a sliding shoji, and more particularly to a sash capable of selecting an appearance and heat insulation performance.

  Conventionally, the sash attached to the opening part of a building frame is properly used for each region. Since the resin has a higher heat insulating property than the metal, the sash using the resin material has a higher heat insulating property. Therefore, it is preferable to adopt the sash using the resin material in a cold region from the viewpoint of energy saving. In addition, resin materials are widely used compared to wooden members because they do not corrode and are easy to mold and process. Therefore, for cold regions that require heat insulation, a resin sash made of a resin material or a composite sash in which a metal material and a resin material are combined is used. The resin sash has a very high heat insulating property, and the composite sash is less expensive than the resin sash and has a metal portion, so that fire resistance can be increased. On the other hand, metal sashes made of a metal material such as aluminum are used for areas that do not require much heat insulation.

  Here, as the composite sash, an aluminum heat shielding structure sash and an aluminum resin composite sash are known. The aluminum heat insulation structure sash is obtained by separating a metal material into an indoor side and an outdoor side and sandwiching a resin material therebetween. In the aluminum resin composite sash, a metal material is provided on the outdoor side, and the exposed surface on the indoor side is covered with a resin material.

  Since the aluminum heat insulation structure sash has a structure in which the resin material connects the indoor side and the metal material on the indoor side, it is necessary to firmly fix the resin material and the metal material. Therefore, fixing by caulking is made. However, when the metal material and the resin material are fixed by caulking, there is a problem that it is difficult to recycle them because it is difficult to separate them later.

  On the other hand, since the aluminum resin composite sash has a resin material disposed on the indoor side of the metal material, the fixing of both is not necessarily performed by caulking, and the resin material can be easily separated from the metal material. be able to. For this reason, it has the advantage that it is easy to recycle and that only the resin material can be replaced. Moreover, since various colors and patterns can be given to the resin material, the design from the indoor side can be improved.

In recent years, there has been a strong demand for recyclability and design for sashes, and as a composite sash, it is advantageous to use an aluminum resin composite sash. The present invention includes this aluminum resin composite sash, and there is a conventional example as disclosed in Patent Document 1, for example. Further, as a conventional example of an aluminum heat insulation structure sash, there is one disclosed in Patent Document 2.

  Regarding the material of the sash, energy saving standards are set for each region. By using a sash that satisfies this standard, it is possible to receive preferential treatment such as an increase in the amount of financing when constructing a house. In addition, after the house is completed, the utility cost can be saved by heat insulation according to the area.

  As an energy saving standard of the sash, for example, there is a next generation energy saving standard (1999 Ministry of Construction Notification No. 998). Table 1 shows an excerpt of this standard. Table 2 shows the names of prefectures corresponding to each region. Table 1 shows (1) heat transmissibility standards and (2) joinery and glass specifications for each region. Next-generation energy-saving standards include (1) or (2) Any one of the criteria may be satisfied. In other words, regardless of the specifications of the joinery and glass, the heat transmissivity shall be below the reference value, or the joinery and glass shall be set to the specified specifications regardless of the value of the heat transmissibility, thereby clearing the energy saving standard. Become.

  As shown in Table 2, the regional categories I and II are the coldest regions, Hokkaido and the northern Tohoku region. Region III is the next coldest region, including the southern Tohoku region, Joshinetsu, Kita Kanto and Hokuriku regions. Furthermore, region classifications IV and V are temperate regions, which are the southern Kanto, Tokai, Kinki, China, Shikoku, and Kyushu regions. And region classification VI is a warmer region and is Okinawa Prefecture.

  Focusing on the specifications of joinery and glass in Table 1, in the case of a single sash, in the regional divisions I and II, a resin sash made of resin material or a wooden sash made of wood entirely, and the above-mentioned aluminum Any of resin composite sashes can be employed. In this area, resin sashes or composite sashes with large air layers are mainly used. And about glass, a low radiation multilayer glass is employ | adopted.

  In the area division III, any of a resin sash, a wooden sash, an aluminum resin composite sash, and an aluminum heat insulation structure sash can be adopted. In this region, resin sashes and wooden sashes have excessive heat insulation performance, so the last two sashes are mainly used. In this case, the aluminum resin composite sash is more advantageous in terms of ease of recycling and design. As for the glass, either two single plates or a multi-layer glass can be selected, but a multi-layer glass is usually used.

  In region classification IV and V, the material of the sash is not asked. For this reason, the metal sash comprised only from the metal material which can be mainly manufactured at low cost is used. As for the glass, either two single plates or a multi-layer glass can be selected, but a multi-layer glass is usually used.

Conventional sashes were configured with different specifications for each region. Therefore, the member made of a metal material and the member made of a resin material are formed with different shapes and dimensions, respectively.
By the way, in regions IV and V, there is a need to provide an aluminum resin composite sash that is made of resin material on the indoor side in order to emphasize the design of the sash. There is also a need to provide a metal sash to reduce costs as much as possible on the condition of satisfying.

  In the former case, an aluminum resin composite sash can be used for region III, but the heat insulation performance is excessive for use in regions IV and V, resulting in a significant increase in cost. In addition, since there is a need for the latter, it is necessary to manufacture a metal sash, and since these are different specifications, the manufacturing cost is high.

  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a view showing a combination of a frame and a shoji in this embodiment. The basic structure of the sash in this embodiment is that the outer shoji 4 and the inner shoji 5 are accommodated in the frame 1 attached to the building opening, and the screen door 6 is accommodated outside the outdoor door. is there. The frame 1 is configured by forming a lower frame 10 and an upper frame 20 and left and right vertical frames 30 and 30 into a rectangular frame, and the outer shoji 4 and the inner shoji 5 have a lower arm 40 and an upper arm. 50 and left and right vertical rods 60 and 60 are assembled into a square shape to form a housing 2, and a glass body 3 is accommodated therein.

  The left side of FIG. 1 shows the lower frame 10 of three types of frames 1. Further, the right side of FIG. 1 shows three types of external shoji 4 and internal shoji 5. A lower frame 10 shown in FIG. 1 (A) is a low heat insulating lower frame including a metal lower frame 11 made of a metal material and an indoor resin lower frame 13 covering the indoor side end. A lower frame 10 shown in FIG. 1B is an intermediate heat insulating lower frame configured by providing an intermediate resin lower frame 12a on the upper surface of the low heat insulating lower frame. A lower frame 10 shown in FIG. 1C is a highly heat-insulating lower frame configured by providing an end surface resin lower frame 12b on the indoor side surface of the middle heat-insulating lower frame.

  The low heat insulating frame having the low heat insulating lower frame shown in FIG. 1A is low in cost but has low heat insulating performance. This low heat insulation frame can mainly prevent dew condensation on the sash interior side. The medium heat insulation frame having the medium heat insulation lower frame shown in FIG. 1B can obtain a medium heat insulation performance at a medium cost. A highly heat-insulating frame having a highly heat-insulating lower frame shown in FIG. 1C is high in cost but has high heat insulating performance. For this reason, the low thermal insulation frame of FIG. 1 (A) can be adopted as a sash for region divisions IV and V, and the middle thermal insulation frame of FIG. 1 (B) and the high thermal insulation frame of FIG. 1 (C). The body can be employed as a sash for Region III.

  The external shoji 4 and the internal shoji 5 shown in FIG. 1 (a) are metal shojis configured by placing a glass body 3 made of double-layer glass in a housing 2 made of a metal material. 1B, the shingles 4 and 5 have a glass body 3 made of multi-layer glass in a housing 2 in which a plate-like resin material is disposed on the exposed surface of a metal material. It is a constructed low thermal insulation shoji. In the case of the outer shoji 4 and the inner shoji 5 shown in FIG. 1 (c), a glass body 3 made of multi-layer glass is placed in a housing 2 in which a resin material having a hollow cross section is disposed on an exposed surface of a metal material. This is a highly insulated shoji screen. Therefore, the metal screen shown in FIG. 1 (a) has low heat insulation performance, the low heat insulation screen shown in FIG. 1 (b) has intermediate heat insulation performance, and the high heat insulation screen shown in FIG. 1 (c) has heat insulation performance. Is expensive.

  Here, each external shoji 4 and internal shoji 5 have the same dimension between the door wheels 43 and 43 provided at the lower end of each shoji. In addition, each frame 1 has the same dimension between the rail cores of the outer rail 11a and the inner rail 11b formed on the upper surface of the lower frame 10, and between the doors 43 and 43 of the respective shojis. The same dimensions as Therefore, each shoji can be stored in any frame 1.

  The metal insulator shown in FIG. 1A or the low insulator shown in FIG. 1B is selectively stored in the low heat insulating frame shown in FIG. Moreover, the high heat insulation shoji of FIG.1 (c) is stored in the middle heat insulation frame of FIG.1 (B). Furthermore, the high thermal insulation shoji of FIG. 1 (c) is stored in the high thermal insulation frame of FIG. 1 (C). If the frame 1 of FIG. 1 (A) or the frame 1 of FIGS. 1 (B) to 1 (C) is selected according to the area where the sash is installed, and FIG. 1 (A) is further selected, The appearance can be selected by selecting a metal screen or a low heat insulation screen, and thereby, a total of four patterns of sashes can be configured.

  Each of these four patterns of sash will be described in detail. FIG. 2 shows a vertical cross-sectional view of a sash for region divisions IV to V, and FIG. 3 shows a cross-sectional view thereof. The sash shown in FIG. 2 and FIG. 3 is configured by selecting the low thermal insulation frame shown in FIG. 1A and selecting and storing the metal shoji shown in FIG.

  The frame 1 includes a metal lower frame 11 made of a metal material, a metal upper frame 21, and left and right metal vertical frames 31 and 31 in a rectangular shape, which are fixed to a building opening. The frame 1 is fixed by screwing the fins 8 provided at the intermediate position in the expected direction over the four circumferences in contact with the building frame. That is, this sash is a so-called semi-external sash. A fixing portion 11d that protrudes toward the indoor side is formed at the lower end of the indoor surface of the metal lower frame 11, and the fixing portion 11d is also screwed to the building frame.

  An outer rail 11a, an inner rail 11b, and a screen door rail 11c are formed on the upper surface of the metal lower frame 11 over substantially the entire length in the longitudinal direction. The outer rail 11a is the outer shoji 4 and the inner rail 11b is the inner shroud 5. The screen door rail 11c guides the screen door 6 in the longitudinal direction of the sash. Further, an outer rail 21a, an inner rail 21b, and a screen door rail 21c are formed on the lower surface of the metal upper frame 21 over substantially the entire length in the longitudinal direction. These are formed at positions corresponding to the rails of the metal lower frame 11, and guide the outer shoji 4, inner shoji 5 and screen door 6 in the longitudinal direction of the sash, respectively.

  On the inner peripheral surface of the metal vertical frame 31, an outer projecting portion 31 a is provided over substantially the entire length in the longitudinal direction at a position facing the side surface in a state in which the outer shoji 4 is closed. Moreover, the inner protrusion part 31b is provided over the substantially whole length of a longitudinal direction in the position which opposes the side surface in the state which closed the inner shoji 5. FIG. These are provided in order to ensure the airtightness and watertightness of the sash when the outer shoji 4 and inner shoji 5 are closed.

  An indoor resin frame is provided at the indoor side end of the frame 1 over the entire circumference. An indoor resin lower frame 13 is provided at the indoor side end of the metal lower frame 11. The indoor resin lower frame 13 is housed in a recess formed between the inner rail 11b and the indoor surface of the metal lower frame 11, and further extends toward the indoor side from the indoor surface of the metal lower frame 11. It has the indoor extension part 13a.

  Similarly, the indoor resin upper frame 23 provided at the indoor side end of the metal upper frame 21 is also housed in a recess formed between the inner rail 21b and the indoor surface of the metal upper frame 21, and further the metal upper frame 21. It has the indoor extension part 23a extended toward the indoor side rather than the indoor surface. Moreover, the indoor resin vertical frame 33 provided at the indoor side end of the metal vertical frame 31 is more chambered than the internal protrusion 31b with respect to the metal vertical frame 31 on the side facing the inner frame 5 in the closed state. It has an indoor extension part 33a provided on the inner side and extending toward the indoor side. An indoor resin vertical frame 33 having the same shape is also provided for the metal vertical frame 31 on the side facing the door 1 in a state where the external shoji 4 is closed.

  In this sash, a part of the inner peripheral surface of the frame 1 is in a state where the metal material is exposed to the indoor side, so that the heat insulation is not sufficiently ensured, but the indoor resin frame extends over the four circumferences of the frame 1. As a result, the heat insulation is slightly higher than the case where the frame body 1 is made of only a metal material, and the design as viewed from the indoor side can be improved.

  In this sash, the casing 2 is composed of a metal lower rod 41 made of a metal material, a metal upper rod 51, and left and right metal vertical rods 61, 61 in a rectangular shape, and a glass body 3 made of multi-layer glass inside. 7 is configured. A door wheel 43 is provided at the lower end of the metal lower arm 41 and is placed on the outer rail 11a or the inner rail 11b so that the shoji can run on the rail of the lower frame 10.

  The sash in which the metal shoji is placed in the low heat insulating frame has the above-described configuration. By adopting double-layer glass for the glass body 3 housed in the housing 2, it is possible to make a sash that satisfies the heat insulation standards for the regional divisions IV to V and suppresses the cost as much as possible.

  Next, a description will be given of a sash formed by placing a low heat insulating shoji in a low heat insulating frame in order to improve the design by arranging a resin material on the indoor side even for the regions IV to V. FIG. 4 shows a longitudinal sectional view of the sash in this case, and FIG. 5 shows a transverse sectional view thereof. The sashes in these figures are configured by selecting the low thermal insulation frame shown in FIG. 1A and selecting and storing the low thermal insulation shoji shown in FIG.

  In this case, since the frame 1 has selected FIG. 1A, it is basically the same as the sash frame 1 shown in FIGS. However, as shown in FIG. 5, the indoor resin vertical frame 33 attached to the metal vertical frame 31 on the side where the external shoji 4 is arranged is arranged so that the metal material is not exposed to the indoor side as much as possible. It has an extending portion 33b extending to the outdoor side of the indoor resin vertical frame 33 attached to the metal vertical frame 31 on the side. The extension part 33b is extended to a position in the vicinity of the indoor surface when the external obstacle 4 is closed. Other configurations of the frame 1 are the same as those of the sash described in FIGS. 2 and 3.

  Next, the external shoji 4 and the internal shoji 5 will be described. The casing 2 constituting these is composed of a composite material in which a metal material is arranged on the outdoor side and a resin material is arranged on the indoor side. The composite material is usually used to improve the design of the sash as viewed from the indoor side and to improve the heat insulation. However, as described above, the insulation standard for the regional classifications IV to V may be the use of double glazing as described above. When a normal composite material is used, the insulation performance becomes excessive and the cost increases. Therefore, the composite material used for the sashes for the regions IV to V only needs to have a function of improving the design as viewed from the indoor side. For this reason, the resin material provided in the housing 2 in this case is formed in a plate shape.

  Here, according to Table 1 showing the heat insulation standard of the sash, even if the resin material is plate-shaped, if it is an aluminum resin composite sash, the specification of the joinery for the region division III is satisfied. However, when the resin material is plate-shaped, it does not satisfy the criteria for the sash heat transmissibility for the regional section III shown in Table 1, so it is not desirable to use it for the regional section III after all. On the other hand, since this sash satisfies both the specifications of the joinery for the regional division IV and the standard of the heat transmissibility, it can be suitably used for the regional division IV.

  The lower rod 40 is composed of an outdoor metal lower rod 41 and a plate-shaped resin lower rod 42 attached to the indoor surface. The resin lower collar 42 is engaged with and fixed to the metal lower collar 41. The upper part of the lower casing 40 is formed in a concave shape so that the glass body 3 can be accommodated while sandwiching the Grechan 7, the outdoor side thereof is constituted by a metallic lower casing 41, and the indoor side is constituted by a resin lower casing 42. Yes. That is, the outdoor surface of the glass body 3 is supported by the metal lower collar 41, and the indoor surface is supported by the resin lower collar 42. Further, a door wheel 43 is provided at the lower end of the lower arm 40, and the outer shoji 4 is placed on the outer rail 11a, and the inner shoji 5 is placed on the inner rail 11b.

  The upper collar 50 is composed of an outer metal upper collar 51 and a plate-shaped resin upper collar 52 attached to the indoor surface. The resin upper collar 52 is engaged with and fixed to the metal upper collar 51. The glass body 3 accommodated in the upper casing 50 is also supported by the metal upper casing 51 on the outdoor surface and the resin upper casing 52 on the indoor surface.

  The vertical hook 60 has a different shape between the frame-side vertical hook 60a and the summoning hook 60b. The frame-side downpipe 60a is composed of a metal downpipe 61 on the outside of the left and right sides and a plate-like resin downpipe 62 attached to the interior surface. The summon bowl 60b is composed only of a summing metal bowl 63 made of a metal material on the outer shoji 4 side, and the summing metal bowl 63 on the inner shoji 5 side and a plate-like summing resin attached to the indoor exposed surface. It is comprised from 框 64. The summoning metal cages 63, 63 have smoke return portions 63a, 63a on the surfaces facing each other, and they are alternated to ensure the airtightness of the sash.

  Moreover, since the indoor exposed surface in the summon metal 5 of the shoji 5 has two surfaces, the indoor surface and the side surface, the summon resin cage 64 has a substantially L-shaped cross section so as to cover these surfaces. . The summing resin bowl 64 is engaged with and fixed to the indoor surface of the summing metal bowl 63 and the outdoor surface which is the back surface thereof. Therefore, an engaging portion 64 a that protrudes in a substantially vertical direction is formed at the outdoor end portion of the summing resin bowl 64.

  The metal downpipe 61 has a concave shape on the inner peripheral surface that holds the glass body 3 while sandwiching the Grechant 7, and the resin downpipe 62 engages with the tip of the downside and presses against the Grechant 7. Therefore, also in the vertical gutter 60, the outdoor surface of the glass body 3 is supported by the metal vertical gutter 61, and the indoor surface is supported by the resin vertical gutter 62, respectively. As a result, the resin downpipe 62 and the Grechant 7 are continuous, and a sash having a good aesthetic appearance that does not expose the metal downpipe 61 to the indoor side can be obtained.

  About the sash which puts a low heat insulation shoji in a low heat insulation frame, it consists of the above structures. For the frame 1, a low thermal insulation shoji using a composite material in which the interior surface of a metal material is covered with a plate-like resin material is selected as a shoji while keeping the cost low by using a low thermal insulation frame. Therefore, although the heat insulating property is not so high, the design property when viewed from the indoor side is not different from that of a normal composite material, and the sash having high design property can be obtained while suppressing the cost. Furthermore, since the sash and the frame 1 of FIGS. 2 and 3 are almost shared, it is possible to further reduce costs by promoting the sharing of components.

  Next, the sash for region division III is demonstrated. FIG. 6 shows a vertical cross-sectional view of a sash in which a highly heat-insulating shoji is housed in a highly heat-insulating frame, and FIG. The sashes in these figures are configured by selecting the highly heat-insulating frame of FIG. 1C and selecting and storing the highly heat-insulating shoji of FIG. 1C. Moreover, FIG.6 and FIG.7 has shown as the accommodation figure which attached the sash to the building opening part. The two sashes in the front are also attached to the building opening in the same manner as in FIGS. 6 and 7 although not shown.

  The frame 1 has a metal lower frame 11, a metal upper frame 21, and left and right metal vertical frames 31, 31 made of a metal material in a rectangular shape, which are fixed to a building frame. A resin lower frame 12 is disposed on the inner side, a resin upper frame 22 is disposed on the indoor side of the metal upper frame 21, and a resin vertical frame 32 is disposed on the indoor side of the metal vertical frame 31. Here, the metal lower frame 11 and the metal vertical frame 31 are the same as the metal lower frame 11 and the metal vertical frame 31 of the frame 1 in the two previous patterns, and share components.

  As for the lower frame 10, the metal lower frame 11 is the same as the metal lower frame 11 of the two previous patterns as described above. Moreover, the point which has provided the indoor resin lower frame 13 which has the indoor extension part 13a in the indoor edge part is also the same. The resin lower frame 12 includes an intermediate resin lower frame 12a covering between the outer rail 11a and the inner rail 11b of the metal lower frame 11, and an end surface resin lower frame 12b covering the indoor surface of the metal lower frame 11 and the indoor surface of the fixing portion 11d. It is composed of.

  The intermediate resin lower frame 12a is provided only in the portion between the outer rail 11a and the inner rail 11b that is exposed to the indoor side in a state where the outer shoji 4 and the inner shoji 5 are closed. That is, the intermediate resin lower frame 12a is provided in the left half region in FIG.

  The end surface resin lower frame 12b has an upper end in contact with the indoor resin lower frame 13, and a lower end engaged and fixed to the end of the fixed portion 11d. The end surface resin lower frame 12 b is provided over substantially the entire length of the metal lower frame 11 in the longitudinal direction. Thus, the end surface resin lower frame 12b improves the heat insulation of the interior surface of the metal lower frame 11 and prevents condensation.

  The upper frame 20 is composed of four members including a metal upper frame 21. A metal upper frame 21 is provided on the most outdoor side. The metal upper frame 21 is formed with fins 8 which are fixed portions to the building frame, and a screen door rail 21c is formed at the outdoor end, and corresponds to the outer rail 11a of the lower frame 10 on the indoor side from the screen door rail 11c. An outer rail 21a is formed.

  A resin upper frame 22 is disposed on the indoor side of the metal upper frame 21.
