[Diagram 2] An enlarged view of the area enclosed by the dashed line in Figure 1. [Diagram 3] FIG. 2 is a longitudinal sectional view of the fitting according to the present invention, with the intermediate portion omitted. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0007] Hereinafter, a fitting A according to an embodiment of the present invention will be described with reference to the drawings. In the following description, the same reference numerals in different drawings indicate parts having the same functions, and duplicated descriptions in each drawing will be omitted as appropriate. In the following description, various members made of resin are members related to heat insulation.
[0008] The fixture A of this embodiment will be described using as an example a sliding window in which an inner screen 2 and an outer screen 3 are arranged so as to be able to slide freely in the width direction (hereinafter referred to as the left-right direction) on a frame 1 fixed to the inner periphery of an opening B1 in a main body B, as shown in Figures 1 and 3.
[0009] [Frame 1 Configuration] Please refer to Figures 1 and 3. The frame 1 has a structure formed by a top frame 10, a bottom frame 11 (see FIG. 3), a left vertical frame 12, and a right vertical frame 13 (see FIG. 1). The upper frame 10 is fixed to the main body B, and is provided with an upper frame inner shoji rail 100 and an upper frame outer shoji rail 101 that protrude downward on the inner circumference. The lower frame 11 is fixed to the frame B and has a lower frame main body 110 and a lower frame cover 111. The lower frame body 110 has a lower frame inner shoji rail 112 and a lower frame outer shoji rail 113 on its inner circumference. The lower frame cover 111 comprises an indoor cover 1110 and a rail-interval cover 1111 made of resin shaped material, and has excellent insulating properties and reduces the step that occurs between the rails of the lower frame 11. The left vertical frame 12 and the right vertical frame 13 are fixed to the main body B as shown in FIG.
[0010] [Configuration of Inner Shoji 2] Please refer to Figures 1 and 3. The inner screen 2 is formed by fitting an inner panel 600 into an inner screen frame 4. The inner shoji frame 4 is composed of an inner joint frame 40, an inner door stop frame 41 (see Figure 1), an inner upper frame 42, and an inner lower frame 43 (see Figure 3).
[0011] [Configuration of inner joint frame 40] Please refer to Figures 1 and 2. The inner joint frame 40 comprises a metal frame material 400 made of aluminum shaped material and a resin frame material 401 made of resin shaped material. The inner joint frame 40 is formed by fastening a metal frame material 400 and a resin frame material 401 together to form an integrated unit.
[0012] The metal frame 400 has an attachment portion 4001, a smoke deflector portion 4002 formed at the outdoor end of the attachment portion 4001, an outdoor outer edge portion 4003, and a visible wall 4004 (see Figure 2) extending on the opposite side of the smoke deflector portion 4002. The resin frame 401 has a hollow frame 4010 located on the projected surface side of the outer periphery of the inner panel 600 with the mounting portion 4001 of the metal frame 400 between them, and an inner side outer edge portion 4011 .
[0013] Please refer to Figure 2. The mounting portion 4001 is plate-shaped and is attached to the projected surface of the inner periphery of the hollow frame 4010 of the resin frame material 401 by fastening it with a screw N. The mounting portion 4001 does not cover the entire visible surface on the inner circumference side of the hollow frame 4010 of the resin frame material 401, and the width of the mounting portion 4001 is such that the outdoor side tip of the mounting portion 4001 is located on the outdoor side further outside than the partition wall 4013 described below, thereby improving insulation. The smoke return section 4002 (inner joint frame side) on the inner screen 2 side is integrally formed at the outside end of the mounting section 4001. When the inner screen 2 and the outer screen 3 are closed, the smoke deflector portion 4002 (inner joint frame side) on the inner screen 2 side fits into the smoke deflector portion 5002 (outer joint frame side) on the outer screen 3 side provided on the outer joint metal frame material 500 in the outer screen frame 5 described later. Furthermore, the smoke deflector section 4002 (inner joint frame side) on the inner screen 2 side and the smoke deflector section 5002 (outer joint frame side) on the outer screen 3 side are brought close to each other in the indoor / outdoor direction by closing the crescent 4016, filling the gap between the metal frame material 400 and the outer joint metal frame material 500 at the outer screen frame 5 to ensure airtightness and soundproofing. The observation wall 4004 overlaps with an observation side step portion 4018 (described later) formed on the exterior side surface of the resin frame material 401. The observation wall 4004 not only improves the strength of the smoke return section 4002 but also serves to position the metal frame 400 . The visible wall 4004 is formed compactly and shorter than the visible width of the exterior side surface of the resin frame material 401. In this way, the inner joint frame 40 is designed so that the proportion of metal frame material 400 is smaller than that of resin frame material 401, resulting in a small total amount of metal and high thermal insulation.
[0014] The hollow frame 4010 of the resin frame material 401 is formed with a hollow portion 4012 extending over the entire area in the vertical direction, and a divided hollow portion 4014 divided by a partition wall 4013 from the hollow portion 4012 . The resin frame material 401 has an increased bending strength due to the hollow portions 4012, the partition walls 4013, and the divided hollow portions 4014 in the hollow frame 4010. The hollow portion 4012 occupies most of the cross section of the hollow frame 4010, and a metallic reinforcing member 4015 is attached within the hollow portion 4012 and has a length that covers almost the entire area of the hollow portion 4012 in the vertical direction. The bending strength of the resin frame 401 is increased by a metallic reinforcing member 4015 attached within the hollow portion 4012 of the hollow frame 4010 . The reinforcing member 4015 is formed in a roughly U-shape when viewed from above, and is attached with its open portion facing the crescent 4016 . Since the reinforcing material 4015 is roughly U-shaped when viewed from above, the bending strength of the inner joint frame 40 can be efficiently increased. The size and number of the divided hollow portions 4014 are arbitrary. The hollow frame 4010 of the resin frame 401 is provided on its inner circumferential surface with a step 4017 to which the mounting portion 4001 of the metal frame 400 is attached. The step portion 4017 is formed to have the same dimensions as the plate thickness of the mounting portion 4001, and when the mounting portion 4001 is attached to the step portion 4017, the inner peripheral surface of the mounting portion 4001 and the inner peripheral surface of the hollow frame 4010 are flush with each other. The end of the step portion 4017 on the indoor side is located on the outdoor side of the partition wall 4013 and is in close proximity to the tip of the mounting portion 4001 when mounted on the step portion 4017. The hollow frame 4010 of the resin frame material 401 has the aforementioned visible side step 4018 formed at the corner portion on the outdoor side. The sight side step 4018 is formed to the same dimensions as the plate thickness of the sight wall 4004, and when the sight wall 4004 is overlapped with the sight side step 4018, the exterior side of the sight wall 4004 and the exterior side of the resin frame material 401 are flush with each other.
[0015] The screw N penetrates the mounting portion 4001, the hollow frame 4010, and the reinforcing material 4015 and is screwed in, thereby fastening the resin frame 401, the reinforcing material 4015, and the metal frame 400 together to form a single unit. The screws N are screwed into a plurality of positions in the vertical direction, and serve to firmly integrate the resin frame material 401, the reinforcing material 4015, and the metal frame material 400 (not shown).
[0016] With this configuration, the metal frame material 400 and the resin frame material 401 are integrated to form an inner joint frame 40 having the necessary strength and thermal insulation properties.
[0017] [Configuration of inner door frame 41] Please refer to Figure 1. The inner door stop frame 41 comprises an inner door stop metal frame material 410 made of an aluminum profile and an inner door stop resin frame material 411 made of a resin profile. The inner door stop frame 41 is formed by integrating an inner door stop resin frame material 411 arranged on the indoor side and an inner door stop metal frame material 410 arranged on the outdoor side through mutual engagement. The inner door stop frame 41 is formed by integrating a high-strength metal inner door stop frame material 410 made of metal with a resin inner door stop frame material 411 made of resin, thereby providing the necessary strength and heat insulation.
[0018] [Configuration of inner upper frame 42] Please refer to Figure 3. The inner upper frame 42 comprises an inner upper metal frame material 420 made of an aluminum profile and an inner upper resin frame material 421 made of a resin profile. The inner upper frame 42 is formed by integrating an inner upper resin frame material 421 arranged on the indoor side and an inner upper metal frame material 420 arranged on the outdoor side through mutual engagement. The inner upper frame 42 has the necessary strength and heat insulation properties by integrating an inner upper metal frame material 420 made of high-strength metal with an inner upper resin frame material 421 made of resin.
[0019] [Configuration of inner bottom frame 43] Please refer to Figure 3. The inner lower frame 43 comprises an inner lower metal frame material 430 made of an aluminum profile, and an inner lower resin frame material 431 made of a resin profile. The inner lower frame 43 is formed by integrating an inner lower metal frame material 430 arranged on the exterior side and an inner lower resin frame material 431 arranged on the interior side through mutual engagement. The inner lower frame 43 has the necessary strength and heat insulation properties by integrating an inner lower metal frame material 430 made of high strength metal and an inner lower resin frame material 431 made of resin.
[0020] [Effects of Inner Screen 2] As described above, such an inner screen 2 has high thermal insulation properties because almost the entire interior side of the inner screen frame 4 is made of resin frame material. Furthermore, since almost the entire exterior side of the inner screen frame 4 of the inner screen 2 is made of metal frame material, the inner screen frame 4 has the necessary strength. Therefore, the inner screen 2 has the necessary strength and thermal insulation properties.
[0021] [Joining structure of inner upper frame 42 and inner lower frame 43 to inner joint frame 40] As shown in FIG. 3, an inner upper frame 42 and an inner lower frame 43 are joined to the inner joint frame 40. The inner upper frame 42 abuts the longitudinal end face of the inner upper frame 42 against the inner peripheral surface of the inner joint frame 40, and is joined to the inner joint frame 40 by screwing from the outer peripheral side of the inner joint frame 40 toward the tapping hole 4201 formed in the inner upper metal frame material 420 of the inner upper frame 42. When screwing this inner upper frame 42, the tip of the screw (not shown) penetrates the inner side wall of the hollow portion 4012 and the mounting portion 4001 and screws into the tapping hole 4201, thereby making the connection between the inner joint frame 40 and the inner upper frame 42 strong. The inner bottom frame 43 is joined to the inner joint frame 40 by abutting the longitudinal end face of the inner bottom frame 43 against the inner peripheral surface of the inner joint frame 40 and screwing it from the outer peripheral side of the inner joint frame 40 toward the tapping hole 4301 formed in the inner lower metal frame material 430 of the inner bottom frame 43. When screwing this inner bottom frame 43, the tip of the screw (not shown) penetrates the inner side wall of the hollow portion 4012 and the mounting portion 4001 and screws into the tapping hole 4301, thereby making the connection between the inner joint frame 40 and the inner bottom frame 43 strong.
[0022] [Configuration of outer screen 3] Please refer to Figures 1 and 3. The outer shoji 3 is made by fitting an outer panel 700 into an outer shoji frame 5 which is made up of an outer joint frame 50, an outer door stop frame 51 (see Figure 1), an outer upper frame 52, and an outer lower frame 53 (see Figure 3).
[0023] [Configuration of outer joint frame 50] Please refer to Figures 1 and 2. The outer joint frame 50 comprises an outer joint metal frame material 500 made of metal aluminum profile material, and an outer joint resin frame material 501 made of resin profile material. The exterior joint frame 50 is formed by integrating an exterior joint metal frame material 500 arranged on the exterior side with an exterior joint resin frame material 501 arranged on the interior side through engagement. The exterior joint frame 50 is formed by integrating a high-strength exterior joint metal frame material 500 made of metal with an exterior joint resin frame material 501 made of resin, thereby providing the exterior joint frame 50 with the necessary strength and heat insulation. The outer joint metal frame material 500 has, at its end on the inside of the room, a smoke deflector portion 5002 (external joint frame side) on the outer screen 3 side mentioned above, which fits into the smoke deflector portion 4002 (inner joint frame side) on the inner screen 2 side.
[0024] [Relationship between the inner joint frame 40 and the outer joint resin frame material 501] As shown in Figure 2, the exterior surface of the inner joint frame 40 and the outer joint resin frame material 501 of the outer joint frame 50 are positioned so as to face each other when the inner screen 2 and the outer screen 3 are in a closed state. The exterior joint resin frame material 501 extends from the base end of the resin frame material 401 facing the exterior side of the interior joint frame 40 to the tip of the smoke return portion 4002 of the metal frame material 400. Therefore, when the outer screen 3 and the inner screen 2 are closed, cold air from outside the room is insulated by the outer joint resin frame material 501, making it difficult for it to reach the smoke return section 4002. In addition, when the outer screen 3 and the inner screen 2 are closed, cold air from outside the room is insulated by the outer joint resin frame material 501, and furthermore, since the resin frame material 401 of the inner joint frame 40 also has insulating properties, it is made even more difficult for the cold air to be transmitted inside the room.
[0025] [Configuration of exterior door frame 51] Please refer to Figure 1. The exterior door stopper frame 51 comprises an exterior door stopper metal frame material 510 made of metal aluminum profile material, and an exterior door stopper resin frame material 511 made of resin profile material. The exterior door contact frame 51 is formed by integrating an exterior door contact metal frame material 510 arranged on the exterior side and an exterior door contact resin frame material 511 arranged on the interior side through mutual engagement. The exterior door stop frame 51 is formed by integrating a high-strength metal exterior door stop frame material 510 made of metal with a resin exterior door stop frame material 511 made of resin, thereby providing the exterior door stop frame 51 with the necessary strength and thermal insulation properties.
[0026] [Configuration of outer upper frame 52] Please refer to Figure 3. The outer upper frame 52 comprises an outer upper metal frame material 520 made of an aluminum profile and an outer upper resin frame material 521 made of a resin profile. The outer upper frame 52 is formed by integrating an outer upper metal frame material 520 arranged on the exterior side and an outer upper resin frame material 521 arranged on the interior side through mutual engagement. The outer upper frame 52 is formed by integrating an outer upper metal frame material 520 made of high-strength metal with an outer upper resin frame material 521 made of resin, thereby providing the outer upper frame 52 with the necessary strength and thermal insulation properties.
[0027] [Configuration of outer frame 53] Please refer to Figure 3. The outer lower frame 53 comprises an outer lower metal frame material 530 made of an aluminum profile and an outer lower resin frame material 531 made of a resin profile. The exterior lower frame 53 is formed by integrating an exterior lower metal frame material 530 arranged on the exterior side and an exterior lower resin frame material 531 arranged on the interior side through mutual engagement. The outer bottom frame 53 is formed by integrating a high-strength outer bottom metal frame material 530 made of metal and an outer bottom resin frame material 531 made of resin, thereby providing the outer bottom frame 53 with the necessary strength and thermal insulation properties.
[0028] [Effects of outer screen 3] As mentioned above, such an outer screen 3 has high thermal insulation properties because almost the entire interior side of the outer screen frame 5 is made of resin frame material. Furthermore, the outer screen 3 has the necessary strength for the outer screen frame 5 since almost the entire exterior side of the outer screen frame 5 is made of metal frame material. Therefore, the outer screen 3 has the necessary strength and insulation properties.
[0029] [Effects of Door and Window A] According to the fitting A having the above-mentioned configuration, almost the entire interior side of the frame 1, inner screen 2 and outer screen 3 are made of resin components, so that insulation on the interior side can be ensured. In addition, by using metal frame materials for the outer sides of the inner screen frame 4 of the inner screen 2 and the outer screen frame 5 of the outer screen 3, the inner screen 2 and the outer screen 3 can have the necessary strength. The resin frame material 401 of the inner screen frame 4 in the inner screen 2 can be made to have high strength by attaching a metal reinforcing material 4015 to the hollow portion 4012. Furthermore, the resin frame material 401 of the inner screen frame 4 in the inner screen 2 can be made to have even greater strength by fastening the mounting portion 4001, the hollow frame 4010, and the reinforcing material 4015 together with screws N. Therefore, it is possible to provide a fitting A that has the necessary strength and also has heat insulating properties.
[0030] The above describes in detail an embodiment of the fitting A according to the present invention with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the present invention includes design changes and the like that do not deviate from the gist of the present invention.
[0031] Furthermore, the above-described embodiments can be combined by utilizing each other's technologies, so long as there are no particular contradictions or problems in the objects, configurations, and the like. [Explanation of symbols]
