Description

[Technical Field]

[0001] The present invention relates to a mounting structure for a fixture and a fixture. [Background technology]

[0002] When fitting a fixture to an opening frame, the dimensions of the opening frame are not always sufficient relative to the dimensions along the projected direction of the frame body. For example, when installing a new fixture on the interior side of an already installed fixture to improve thermal insulation, the frame body must be attached to the opening frame formed by the frame of the existing fixture, and the frame body may protrude beyond the opening frame into the interior. For this reason, in the past, a reinforcing material called a false frame was added to the interior side of the opening frame formed by the frame, and the new fixture was then attached to the opening frame formed by the frame and reinforcing material (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-297831 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the above-mentioned mounting structure, although the reinforcing material makes it possible to ensure the mounting strength of new fixtures, the number of parts increases, which is not necessarily desirable when considering manufacturing costs and ease of installation.

[0005] In view of the above-mentioned situation, the present invention aims to provide a fitting mounting structure and fitting that can mount a frame body without increasing manufacturing costs or complicating installation work, even when the dimensions of the opening frame are not necessarily sufficient compared to the dimensions along the projected direction of the frame body. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the mounting structure for fittings of the present invention comprises a frame body and a shoji screen that is slidably arranged on the frame body via a rail portion of the lower frame that constitutes the frame body, and is a mounting structure for fittings that is installed on an opening frame via the frame body, characterized in that the rail portion is located on the outside of the room relative to the inside edge portion of the opening frame, and the lower frame is mounted to the opening frame with a part of the lower frame protruding inside the room. Furthermore, the fixture of the present invention comprises a frame body and a shoji screen that is slidably arranged on the frame body via a rail portion of the lower frame that constitutes the frame body, and is installed in an opening frame via the frame body, characterized in that the rail portion is located on the outside of the room relative to the inside edge of the opening frame, and the lower frame is attached to the opening frame with a part of the lower frame protruding inside the room. [Effects of the Invention]

[0007] According to the present invention, the rail portion of the lower frame is located on the outside of the interior edge of the opening frame, so the load of the shoji screen applied to the rail portion can be supported by the opening frame, eliminating the need for reinforcing materials such as a frame. This means that the number of parts does not increase, and there is no concern that this will increase manufacturing costs or make installation work more complicated.

[0009] A preferred embodiment of the fitting mounting structure according to the present invention will be described in detail below with reference to the accompanying drawings. Note that, for convenience, the terms "invisible direction" and "visible direction" will be used below. The "invisible direction" is the direction along the depth of the fitting, as indicated by arrow A in the drawing. A surface along the invisible direction will be referred to as a "visible face." The "visible direction" is the direction perpendicular to the invisible direction for items that extend horizontally, such as a sill. For items that extend vertically, such as a vertical frame, the "visible direction" is the horizontal direction perpendicular to the invisible direction. A surface along the invisible direction will be referred to as a "visible face."

[0010] (Embodiment 1) Figures 1 and 2 show a fixture to which a mounting structure according to a first embodiment of the present invention is applied. The fixture exemplified here is a new interior window to be installed inside an existing fixture. The already installed fixture (hereinafter referred to as the existing fixture, with the term "existing" being used to refer to the components of the existing fixture) is a sliding window, as shown in Figures 3 and 4, which includes an existing frame 10 and an existing outer shoji screen 20A and an existing inner shoji screen 20B slidably supported on the existing frame 10. The existing frame 10 is constructed by assembling an existing upper frame 11, an existing lower frame 12, and existing left and right vertical frames 13 all around. The existing upper frame 11, the existing lower frame 12, and the existing vertical frames 13 are attached to a structural body opening B0 by screwing screw members S1 into the structural body B, which includes left and right pillars B1, an upper lintel B2, and a lower window sill B3. The structural opening B0 is configured to have a rectangular opening with pillars B1, lintels B2, and window sills B3. As is clear from the figure, the dimensions of the existing upper frame 11, existing lower frame 12, and existing vertical frame 13 along the projection direction are smaller than the dimensions of the structural opening B0 along the projection direction. In the example shown, the existing frame body 10 is attached to the portion of the structural opening B0 closer to the exterior side, and frames 1 are attached around the four sides of the portion of the structural opening B0 that is on the interior side. The existing lower rail portion 12a on the exterior side of the existing lower frame 12 and the existing upper rail portion 11a on the exterior side of the existing upper frame 11 are both positioned inside the room relative to the exterior edge of the structural opening B0. The frames 1 are each made of thick wooden boards and are attached to the main body B in a manner that covers the portion of the main body opening B0 that is closer to the interior than the existing frame body 10, thereby forming an opening frame 2 on the interior side of the existing frame body 10. The interior side edge of each frame 1 protrudes into the room beyond the interior material 3. The existing outer shoji screen 20A and the existing inner shoji screen 20B are slidably supported by the existing upper rail portions 11a, 11b of the existing upper frame 11 and the existing lower rail portions 12a, 12b of the existing lower frame 12. The existing vertical frame 21 that joins the existing inner shoji screen 20B is configured so that its middle portion in the height direction protrudes beyond the existing frame body 10 toward the interior side.

[0011] On the other hand, the new fitting (hereinafter referred to as the new fitting, and the term "new" is used for the components of the new fitting) to be installed as an interior window in a position closer to the interior side of the opening frame 2 formed by the frame 1 is called a sliding window, which comprises a new frame body (frame body) 30 and a new outer shoji (shōji) 40A and a new inner shōji (shōji) 40B that are slidably supported on the new frame body 30. The new frame body 30 is formed by assembling a new upper frame 31, a new lower frame (bottom frame) 32, and new left and right vertical frames 33 all around. The new outer shōji 40A and the new inner shōji 40B are each formed by attaching a new upper frame 42, a new lower frame 43, and new left and right vertical frames 44 to the four perimeters of a panel 41 such as double-glazed glass. The new upper frame 31, new lower frame 32, and left and right new vertical frames 33 that make up the new frame body 30, as well as the new upper frame 42, new lower frame 43, and left and right new vertical frames 44 that make up the new outer shoji screen 40A and the new inner shoji screen 40B, are all extruded shapes molded from resin, and are configured so that the entire longitudinal length has a uniform cross-sectional shape. Below, we will explain in detail the configuration of the new upper frame 31, new lower frame 32, and new vertical frames 33 that make up the new frame body 30, and also explain the characteristic parts of the present invention.

[0012] As shown in Figure 5, the new upper frame 31 has an upper base plate 31a, two new upper rails 31b and 31c, and an upper inner sight plate 31d. The upper base plate 31a extends almost horizontally along the projection direction. The two new upper rails 31b and 31c extend in the projection direction from the projection surface on the inner periphery of the upper base plate 31a toward the inner periphery, and are configured to have the same extension dimensions. The upper inner sight plate 31d extends in the projection direction from the interior edge of the upper base plate 31a toward the inner periphery. The extension dimension of the upper inner sight plate 31d is smaller than the extension dimension of the new upper rails 31b and 31c.

[0013] The upper substrate portion 31a is provided with an upper index groove 31e, an upper outer fin portion 31f, and an upper inner fin portion 31g. The upper index groove 31e is a narrow recess provided on the outer peripheral projection surface in a portion that is closer to the interior than the interior-facing surface of the new upper rail portion 31c on the indoor side, and is formed along the entire length of the new upper frame 31. As is clear from the figure, the outer peripheral projection surface of the upper substrate portion 31a is flat in the portion that is closer to the interior than the upper index groove 31e. The upper outer fin portion 31f extends at an angle from the outer peripheral edge of the upper substrate portion 31a toward the outer peripheral side, gradually inward toward the interior, and its extending edge protrudes outward beyond the outer peripheral projection surface of the upper substrate portion 31a. The upper inner fin 31g extends from the portion of the projected surface of the outer periphery of the upper substrate 31a that is closer to the exterior than the upper index groove 31e, gradually sloping outward toward the exterior. The extending edge of the upper inner fin 31g protrudes further outward than the edge of the outer periphery of the upper substrate 31a. The upper outer fin 31f and the upper inner fin 31g are integrally molded from a resin that is softer than the other portions of the upper substrate 31a, allowing for relatively easy elastic deformation. Upper outer peripheral recesses 31h are provided in the portion of the projected surface of the outer periphery of the upper substrate 31a located between the new upper rails 31b and 31c and in the portion located between the outdoor-side new upper rail 31b and the upper outer fin 31f. Furthermore, two upper contact ribs 31j are provided in the upper outer peripheral recess 31h between the new upper rail portions 31b and 31c. The protruding height of the upper contact ribs 31j is set so as to be flush with the projected surface of the outer periphery of the upper base plate portion 31a.

[0014] As shown in FIG. 6, the new lower frame 32 includes a lower base plate 32a, two new lower rails (rails) 32b and 32c, and a lower inner sight plate 32d. The lower base plate 32a extends horizontally along the projection direction and is configured so that its dimension along the projection direction is approximately the same as that of the upper base plate 31a. The two new lower rails 32b and 32c extend inward in the projection direction from portions of the projection surface on the inner periphery of the lower base plate 32a that correspond to the new upper rails 31b and 31c of the new upper frame 31, and are configured so that they have the same extension dimensions. The extension dimensions of the new lower rails 32b and 32c are smaller than those of the new upper rails 31b and 31c. The lower inner sight plate 32d extends in the projection direction from the interior edge of the lower base plate 32a toward the inner periphery. The extension dimension of the lower inner sight plate portion 32d is approximately equal to the extension dimension of the newly installed lower rail portions 32b, 32c.

[0015] The lower base plate portion 32a is provided with a lower index groove (index portion) 32e, a lower outer fin (fin portion) 32f, and a lower inner fin (fin portion) 32g. The lower index groove 32e is a narrow recess provided on the outer peripheral projection surface in a portion that is closer to the interior than the interior-facing surface of the newly installed lower rail portion 32c on the indoor side, and is formed along the entire length of the new lower frame 32. As is clear from the figure, the outer peripheral projection surface of the lower base plate portion 32a is flat in the portion that is closer to the interior than the lower index groove 32e. The lower outer fin portion 32f extends at an angle from the outer peripheral edge of the lower base plate portion 32a toward the outer peripheral side, gradually inward toward the interior, and its extending edge protrudes outward beyond the outer peripheral projection surface of the lower base plate portion 32a. The lower inner fin 32g extends from a portion of the projected surface of the outer periphery of the lower base plate 32a that is closer to the exterior than the lower index groove 32e, gradually sloping outward toward the exterior. The extending edge of the lower inner fin 32g protrudes further outward than the edge of the outer periphery of the lower base plate 32a. The lower outer fin 32f and the lower inner fin 32g are integrally molded from a resin that is softer than the other portions of the lower base plate 32a, allowing for relatively easy elastic deformation. Lower outer peripheral recesses 32h are provided in the projected surface of the outer periphery of the lower base plate 32a in the portions located between the new lower rail portions 32b and 32c and in the portions located between the new lower rail portion 32b on the exterior side and the lower outer fin 32f. Furthermore, two lower abutment ribs 32j are provided in the lower outer peripheral recess 32h between the newly installed lower rail portions 32b and 32c. The protruding height of the lower abutment ribs 32j is set so as to be flush with the projected surface of the outer periphery of the lower base plate portion 32a.

[0016] As shown in Figure 7, the new vertical frame 33 is configured to be symmetrical on the left and right, and each includes a vertical base plate portion 33a, a partition plate portion 33b, and a vertical inner sight plate portion 33c. The vertical base plate portion 33a extends approximately vertically along the projection direction. The dimension of the vertical base plate portion 33a along the projection direction is approximately the same as that of the upper base plate portion 31a. The partition plate portion 33b extends in the projection direction from the middle of the projection surface on the inner periphery of the vertical base plate portion 33a toward the inner periphery. The extension dimension of the partition plate portion 33b is approximately equal to the extension dimension of the new lower rail portions 32b and 32c. The vertical inner sight plate portion 33c extends in the projection direction from the interior edge of the vertical base plate portion 33a toward the inner periphery. The extension dimension of the vertical inner sight plate portion 33c is slightly larger than the extension dimension of the partition plate portion 33b.

[0017] The vertical base plate portion 33a is provided with a vertical outer fin portion 33d and a vertical inner fin portion 33e. The vertical outer fin portion 33d extends from the outdoor edge of the vertical base plate portion 33a toward the outer periphery, sloping gradually inward toward the room, with the extended edge portion protruding outward beyond the outer periphery of the projected surface of the vertical base plate portion 33a. The vertical inner fin portion 33e extends from the portion of the projected surface of the outer periphery of the vertical base plate portion 33a between the vertical inner sight plate portion 33c and the partition plate portion 33b, sloping gradually outward toward the room, with the extended edge portion protruding outward beyond the outer periphery of the outer periphery of the vertical base plate portion 33a. More specifically, the dimension along the projection from the interior edge of the vertical base plate 33a to the vertical inner fin 33e is greater than the dimension along the projection from the interior edge of the lower base plate 32a to the lower index groove 32e, but smaller than the dimension along the projection from the interior to the newly installed lower rail 32c. As is clear from the figure, the projection surface of the vertical base plate 33a on the outer periphery is flattened from the portion facing the interior relative to the vertical inner fin 33e. The vertical outer fin 33d and the vertical inner fin 33e are integrally molded from a softer resin than the other portions, such as the vertical base plate 33a, allowing for relatively easy elastic deformation. A vertical outer peripheral recess 33f is provided in the portion of the projection surface of the vertical base plate 33a located between the vertical outer fin 33d and the vertical inner fin 33e. Two vertical abutment ribs 33g are provided on both sides of the partition plate portion 33b in the vertical outer peripheral recess 33f. The protruding height of the vertical abutment ribs 33g is set so as to be flush with the projected surface of the outer periphery of the vertical base plate portion 33a.

[0018] The new upper frame 31, new lower frame 32, and left and right new vertical frames 33 configured as described above are positioned relative to the frame 1 below, for example, using the new lower frame 32 as a reference. The new upper frame 31 and new vertical frames 33 are then positioned relative to the frame 1 and attached to the opening frame 2. To attach the new upper frame 31, new lower frame 32, and left and right new vertical frames 33 to the opening frame 2, screw members S2 are threaded into the frame 1 via the upper substrate portion 31a, lower substrate portion 32a, and vertical substrate portion 33a, respectively. As shown in FIG. 8 , resin-molded cap members C are attached to both ends of the new vertical frame 33. The cap members C are attached so as to cover the connection between the new vertical frame 33 and the new upper frame 31 and the connection between the new vertical frame 33 and the new lower frame 32, respectively. The cap members C have index grooves c1 at positions corresponding to the lower index grooves 32e.

[0019] Here, when positioning the new lower frame 32 relative to the opening frame 2, as shown in Figure 9, the new lower frame 32 can be positioned on the inner peripheral projection surface of the frame 1 so that the lower index groove 32e and index groove c1 coincide with the interior edge of the frame 1, or so that the lower index groove 32e and index groove c1 face the interior peripheral projection surface of the frame 1. As described above, the lower index groove 32e and index groove c1 are provided on the outer peripheral projection surface of the new lower frame 32, in a portion that is closer to the interior side than the new lower rail portion 32c on the interior side. Therefore, when the new lower frame 32 is positioned relative to the frame 1 using the lower index groove 32e and index groove c1 as references, the new lower rail portion 32c on the interior side is located outside the interior edge of the frame 1. In other words, both of the new lower rail portions 32b and 32c are supported by the frame 1, but some of them protrude into the room. As a result, the load of the new outer shoji screen 40A and the new inner shoji screen 40B applied to the new lower rails 32b and 32c is supported by the window sill B3 via the frame 1. Therefore, even if the frame 1's dimensions along the projection direction are insufficient, the new lower frame 32 can be installed without adding reinforcing materials such as a sill. This avoids an increase in the number of parts, increases in manufacturing costs, and complicated installation work. Furthermore, the outer projection surface of the portion of the new lower frame 32 that protrudes into the room is flat, eliminating the risk of compromising the appearance quality. Furthermore, when the new lower frame 32 is installed as described above, the lower outer fin portion 32f and the lower inner fin portion 32g each abut against the projection surface on the inner peripheral side of the frame 1, ensuring watertightness and airtightness between the frame 1 and the new lower frame 32. As described above, the lower outer fin portion 32f and the lower inner fin portion 32g are integrally molded with the new lower frame 32, and the number of parts does not increase.

[0020] The new upper frame 31, which is attached to the opening frame 2 using the new lower frame 32 as a positioning reference, will have a portion protruding into the room with the upper index groove 31e aligned with the interior edge of the upper frame 1, similar to the new lower frame 32 described above. The outer peripheral surface of the part of the new upper frame 31 that protrudes into the room will be exposed to the outside, but because it is flat, there is no risk of the appearance quality being impaired even if it is not covered by a false frame. In addition, the upper outer fin portion 31f and the upper inner fin portion 31g of the new upper frame 31 will be in abutment with the interior peripheral surface of the frame 1, ensuring watertightness and airtightness between the frame 1 and the new upper frame 31.

[0021] Similarly, the new vertical frame 33 will have a portion protruding into the room with its vertical inner fin-like portion 33e coinciding with the interior edge of the frame 1. The outer peripheral visible surface of the portion of the new vertical frame 33 that protrudes into the room is flat, so there is no risk of the appearance quality being impaired even if it is not covered by a false frame. Furthermore, the new vertical frame 33 will have its vertical outer fin-like portion 33d and vertical inner fin-like portion 33e abutting against the inner peripheral visible surface of the frame 1, ensuring watertightness and airtightness between the frame 1 and the new vertical frame 33.

[0022] (Embodiment 2) Figures 10 and 11 show a fixture to which a mounting structure according to a second embodiment of the present invention is applied. Like the first embodiment, the fixture illustrated here is a new interior window installed on the interior side of an existing fixture. However, the configuration of the opening frame installed on the interior side of the existing fixture differs from that of the first embodiment. That is, in the fixture according to the second embodiment, as shown in Figures 12 and 13, an existing frame 10 is attached to the portion of the building frame B0 that is closer to the exterior side of the building. Frame plate materials 4 made of the same material as the interior material 3 are attached to the four peripheries of the interior side of the building frame B0, thereby forming an opening frame 5 with the end faces of the frame plate materials 4 and the interior material 3. The frame plate materials 4 are attached to the building frame B so as to cover the portion of the building frame B0 that is closer to the interior side than the existing frame 10, and their exterior edges are attached to the building frame B so that they approximately match the interior surface of the interior material 3. A decorative sheet material 6 is continuously disposed on the visible surface of the interior material 3, extending from the interior surface to the inner periphery of the frame board material 4. The configurations of the existing fixtures and new fixtures are the same as in embodiment 1. In embodiment 2, the same components as in embodiment 1 are designated by the same reference numerals.

[0023] When providing the new upper frame 31, new lower frame 32, and new left and right vertical frames 33 to the opening frame 5 described above, the new lower frame 32 is used as a reference to position the frame 5 below, and then the new upper frame 31 and new vertical frames 33 are positioned relative to the opening frame 5 before being attached to the opening frame 5. To attach the new upper frame 31, new lower frame 32, and new left and right vertical frames 33 to the opening frame 5, screw members S3 are threaded from the frame plate material 4 to the skeleton B via the upper base plate portion 31a, lower base plate portion 32a, and vertical base plate portion 33a, respectively.

[0024] Here, when positioning the new lower frame 32 relative to the opening frame 5, as shown in Figure 14, the new lower frame 32 can be positioned on the inner peripheral surface of the opening frame 5 so that the lower index groove 32e and index groove c1 match the indoor surface of the interior material 3, or so that the lower index groove 32e and index groove c1 face the end face of the interior material 3 or the inner peripheral surface of the frame plate material 4. The new lower frame 32 positioned and placed on the opening frame 5 using the lower index groove 32e and index groove c1 as references will have a portion protruding into the room, with the new lower rail portion 32c on the indoor side positioned outside the indoor edge of the opening frame 5, and the load of the new outer shoji screen 40A and the new inner shoji screen 40B applied to the new lower rail portions 32b, 32c will be supported by the window sill B3 via the frame plate material 4. This makes it possible to install the new lower frame 32 without the need for reinforcing materials such as a sill, even when the dimensions of the opening frame 5 along the projection direction are insufficient, and does not lead to increased manufacturing costs or complicated installation work due to an increased number of parts. Moreover, the outer projection surface of the part of the new lower frame 32 that protrudes into the room is configured flat, and the lower outer fin portion 32f and the lower inner fin portion 32g each abut against the projection surface on the inner peripheral side of the opening frame 5. As a result, it is possible to prevent a situation in which the appearance quality is impaired and to ensure watertightness and airtightness between the new lower frame 32 and the opening frame 5.

[0025] The new upper frame 31 attached to the opening frame 5 using the new lower frame 32 as a reference has a portion that protrudes into the room, with the upper index groove 31e aligned with the interior surface of the interior material 3, similar to the new lower frame 32 described above. Similarly, the new vertical frame 33 has a portion that protrudes into the room, with the vertical inner fin portion 33e aligned with the interior surface of the interior material 3. Because the outer peripheral surfaces of the portions of the new lower frame 32 and new vertical frame 33 that protrude into the room are all flat, there is no risk of impairing the appearance quality even if they are not covered by a sill frame. In addition, the upper outer fin portion 31f, upper inner fin portion 31g, vertical outer fin portion 33d, and vertical inner fin portion 33e each abut against the inner peripheral surface of the opening frame 5, ensuring watertightness and airtightness between the opening frame 5 and the new vertical frame 33.

[0026] In the above-described embodiment, an example of a fixture that is attached to an opening frame provided on the interior side of an existing fixture is shown, but the present invention is not limited to this and can be applied to an opening frame that does not have an existing fixture. Also, although an example of a fixture equipped with a new outer shoji screen 40A and a new inner shoji screen 40B is shown, the present invention can also be applied to a single-sliding window configured so that only the new inner shoji screen 40B is slidable.

[0027] Furthermore, in the above-described embodiment, the lower index groove 32e is provided in the new lower frame 32 and the index groove c1 is provided in the cap member C, which facilitates positioning of the opening frame and the new lower frame 32. However, an index portion is not necessarily required. In the above-described embodiment, when an index portion is provided, the lower index groove 32e is provided in a portion closer to the interior than the new lower rail portion 32c provided on the interior side. However, the lower index groove 32e may be provided anywhere on the interior side, including the intersection of the interior facing surface of the new lower rail portion 32c and the inner peripheral facing surface of the lower base plate portion 32a. In other words, it is sufficient that the index groove 32e is provided on the interior side of the position where the load of the shoji 40B is applied to the lower base plate portion 32a via the new lower rail portion 32c. Furthermore, while the index grooves 32e and c1 are exemplified as the index portion, a groove is not necessarily required in the present invention. For example, in the case of the new lower frame 32, the lower inner fin portion 32g may be used as the indicator portion, or a boundary line may simply be provided, or the molding boundary line of two-color molding may be configured as the indicator portion. Also, in the case of the cap member C, a linear protrusion may be provided as the indicator portion. Furthermore, it is not necessary to provide an indicator portion on both the new lower frame 32 and the cap member C; it is sufficient if one of them is provided. Furthermore, although an indicator portion is also provided on the new upper frame 31, this is not limiting.

[0028] Furthermore, in the above-described embodiment, an opening frame is exemplified as being constructed from a frame and a frame plate material, but the present invention is not limited to these, and the opening frame may also be constructed from a frame material formed from a metal such as an aluminum alloy.
