Description

[Technical Field]

[0001] The present invention relates to fixtures such as fixed windows that are constructed by placing a surface material within a frame body formed by a frame material having a metal frame material on the outside of the room and a resin frame material on the inside of the room. [Background technology]

[0002] A window with a glass panel arranged within a frame has been known as a conventional fixture (see Patent Document 1). The frame is composed of upper and lower horizontal frames (upper and lower frames) and left and right vertical frames formed from metal extrusions, and a synthetic resin extrusion. The synthetic resin extrusions have a main body portion that is attached to the vertical and horizontal frames, respectively, and an interior piece portion that extends from the main body portion toward the interior of the room. The interior piece portion is located on a step formed on the inner surface of the frame that forms the building opening, and is configured so that the gap between the interior piece portion and the frame is not noticeable.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-105557 Summary of the Invention [Problem to be solved by the invention]

[0004] However, for example, if the window described in Patent Document 1 is installed in a frame that does not have the aforementioned step, there is a risk that the gap between the interior piece of the synthetic resin extruded profile and the frame will be noticeable from the inside of the room. For this reason, it is possible to make the gap between the interior piece and the frame less noticeable from the inside of the room by tilting the interior piece toward the outer periphery of the frame relative to the main body so that the position of the interior end of the interior piece is closer to the outer periphery of the frame than the position of the inner periphery of the main body. However, as described above, if a synthetic resin extruded profile having an inclined interior portion is assembled in the same way to both the vertical and horizontal frames, a gap will be formed between the interior portion of the synthetic resin extruded profile assembled to the vertical frame and the interior portion of the synthetic resin extruded profile assembled to the horizontal frame, which may degrade the design as seen from inside the room (interior design).

[0005] The present invention aims to provide a fixture that can reduce the risk of the interior design being compromised. [Means for solving the problem]

[0006] The building fixture of the present invention is a building fixture comprising a frame body having an upper frame, a lower frame, and left and right vertical frames, and a surface material placed within the frame body, wherein the upper frame, the lower frame, and the left and right vertical frames each comprise a metal frame material on the outside of the room and a resin frame material on the inside of the room that is attached to the metal frame material, the resin frame materials in the upper frame, the lower frame, and the left and right vertical frames each have the same cross-sectional shape along a direction perpendicular to their longitudinal direction, the resin frame material has a main body portion with an inner surface portion, and an interior piece portion extending from the main body portion toward the interior of the room, the interior piece portions in the left and right vertical frames are positioned so that the positions of their interior ends are on the left and right outer sides of the positions of the inner surface portions in the left and right vertical frames, and the interior piece portions in the upper frame and the lower frame abut against the interior piece portions in the left and right vertical frames. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide fittings that can reduce the risk of deterioration in the interior design. [Brief explanation of the drawings]

[0009] [Configuration of this embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 3, the fixed window 1 according to this embodiment is a fixture installed in a building opening 6, such as a picture frame formed in a building skeleton 5, and comprises a window frame 2 (frame body) and a panel 3 placed in an opening 7 defined by the window frame 2. The window frame 2 comprises an upper frame 20, a lower frame 30, and left and right vertical frames 40A, 40B, which are framed together. The panel 3 is made up of a multi-layer glass panel, but may also be a single layer. In the following description, the left-right direction of the fixed window 1 is the X-axis direction, the up-down direction of the fixed window 1 is the Y-axis direction, and the projection direction of the fixed window 1 is the Z-axis direction. The X, Y, and Z-axis directions are perpendicular to each other.

[0010] As shown in Figure 2, the upper frame 20 comprises an upper metal frame material 21 (metal frame material) on the outdoor side made of extruded aluminum, and a resin frame material 60A made of extruded synthetic resin attached to the upper metal frame material 21. Upper metal frame material 21 has an upper visible surface portion 22 that forms its main body, an attachment piece portion 24 that extends upward from upper visible surface portion 22, and an engaged portion 25 formed on the indoor side of upper visible surface portion 22, and an aluminum upper holding piece portion 23 (exterior visible surface portion) that extends downward is engaged with upper visible surface portion 22, and mounting piece portion 24 is screwed to building skeleton 5. Upper holding piece portion 23 abuts against the outdoor surface 3A of panel 3, and engaged portion 25 is positioned indoors relative to upper holding piece portion 23 and attachment piece portion 24, and engages with resin frame material 60A that holds down indoor surface 3B of panel 3. The engaged portion 25 has a first lateral engaged portion 51 and a second lateral engaged portion 55 that is located closer to the interior of the room than the first lateral engaged portion 51. The first lateral engaged portion 51 and the second lateral engaged portion 55 of the upper frame 20 are formed in the same manner as the first lateral engaged portion 51 and the second lateral engaged portion 55 of the lower frame 30, and are arranged upside down. The configurations of the first lateral engaged portion 51 and the second lateral engaged portion 55 will be described later. The resin frame material 60A and the resin frame materials 60B and 60C described later are each composed of the same shaped resin frame material 60, and their cross-sectional shapes perpendicular to the longitudinal direction are identical to each other. Therefore, the configuration of the resin frame material 60 will be described in detail later, and the configurations of the resin frame materials 60A, 60B, and 60C will be appropriately designated by the same symbols.

[0011] As shown in Figures 2 and 5, the lower frame 30 comprises a lower metal frame material 31 (metal frame material) on the outdoor side made of extruded aluminum, and a resin frame material 60B made of extruded synthetic resin attached to the lower metal frame material 31. The lower metal frame material 31 has a lower frame outer periphery 32 that constitutes the frame outer periphery of the window frame 2, a bottom surface 33 that is continuous with the inner periphery of the lower frame outer periphery 32 in the Y-axis direction and extends along the Z-axis, a rising surface 34 that rises from the indoor end of the bottom surface 33, an interior-facing surface 35 that is on the indoor side of the rising surface 34, a continuous portion 36 that is continuous along the Z-axis and extends between the rising surface 34 and the interior-facing surface 35, a first horizontal engaged portion 51 formed between the continuous portion 36 and the rising surface 34, and a second horizontal engaged portion 55 formed between the continuous portion 36 and the interior-facing surface 35. An engaged portion 37 is formed by the first horizontal engaged portion 51 and the second horizontal engaged portion 55 of the lower metal frame material 31. The lower frame outer periphery 32 is formed with an attachment piece 38 that extends downward and is fastened to the building skeleton 5 with a screw. The bottom surface 33 has a raised portion formed at its outer end, and an aluminum lower holding piece 39 (exterior-facing surface) extends upward and engages with this portion. The lower holding piece 39 abuts against the outer surface 3A of the panel 3.

[0012] 5, the first horizontal engaged portion 51 of the lower metal frame material 31 has a horizontal piece 52 along the Z-axis direction, a vertical piece 53 along the Y-axis direction, and a horizontal piece 54 along the Z-axis direction that is located closer to the inner periphery of the frame in the Y-axis direction (here, the upper side) than the horizontal piece 52. This first horizontal engaged portion 51 is formed in a U-shaped cross section, with the horizontal piece 52 continuing to the raised surface portion 34, the vertical piece 53 continuing to the horizontal piece 52, and the horizontal piece 54 continuing to the vertical piece 53. In addition, the vertical piece 53 is continuing to the continuing portion 36. The second horizontal engaged portion 55 of the lower metal frame material 31 is positioned closer to the interior of the room than the first horizontal engaged portion 51, and has a horizontal piece 56 along the Z-axis direction and a vertical piece 57 along the Y-axis direction, with a claw portion 58 formed at the end of the vertical piece 57 on the inner periphery of the frame in the Y-axis direction. The horizontal piece 56 is continuous with the interior visible surface portion 35. The vertical piece 57 is continuous with the continuous portion 36 and extends further toward the inner periphery of the frame in the Y-axis direction than the continuous portion 36. Therefore, the claw portion 58 is located closer to the inner periphery of the frame in the Y-axis direction than the first horizontal engaged portion 51.

[0013] As shown in Figure 3, the left and right vertical frames 40A, 40B are configured similarly to each other and are arranged in opposite directions, so below we will explain the left vertical frame 40A in Figure 3, and the right vertical frame 40B will be appropriately designated by the same symbol. As shown in Figures 3 and 4, the vertical frame 40A comprises a vertical metal frame material 41 (metal frame material) on the outdoor side made of extruded aluminum, and a resin frame material 60C made of extruded synthetic resin attached to the vertical metal frame material 41. The vertical metal frame member 41 has a vertical projection surface portion 42 that forms its main body, an attachment piece portion 43 that extends laterally from the vertical projection surface portion 42, an interior-facing surface portion 44 that is continuous with the vertical projection surface portion 42, and an extension piece portion 45 that extends from the end of the interior-facing surface portion 44 on the frame's inner periphery in the X-axis direction to the exterior of the room. The extension piece portion 45 is formed with an engagement piece 48 that has a first vertical engagement piece 46 and a second vertical engagement piece 47. An aluminum vertical holding piece portion 49 (exterior-facing surface portion) that extends toward the frame's inner periphery in the X-axis direction is engaged with the vertical projection surface portion 42. The vertical holding piece portion 49 abuts against the exterior surface 3A of the panel 3. The engagement piece 48 engages with a resin frame member 60C that holds down the interior surface 3B of the panel 3.

[0014] As shown in Figure 4, the first vertical engaged portion 46 of the vertical metal frame material 41 has a base piece portion 461 protruding from the extension piece portion 45 toward the inner periphery of the frame in the X-axis direction, a step portion 462 bent from the base piece portion 461 toward the outside of the room, and an end piece portion 463 protruding from the step portion 462 toward the inner periphery of the frame in the X-axis direction. The second vertical engaged portion 47 of the vertical metal frame material 41 is positioned on the indoor side of the first vertical engaged portion 46, and has an engaged piece portion 471 protruding from the extending piece portion 45 toward the inner periphery of the frame in the X-axis direction, and a claw portion 472 formed at the tip of the engaged piece portion 471. The tip position of the end piece portion 463 and the tip position of the claw portion 472 are positioned at approximately the same protruding position in the X-axis direction.

[0015] As shown in Figures 4 and 5, the resin frame material 60 has a main body portion 61 that presses the interior surface 3B of the panel 3, and an interior piece portion 70 that extends from the main body portion 61 toward the interior of the room and has a flat inner surface, and in this embodiment is configured as a pressing edge. The main body 61 has an exterior-facing surface 62, an inner peripheral surface 63 with a flat inner peripheral surface, an outer peripheral surface 64, an interior-facing surface 65, a first engagement portion 66, and a second engagement portion 67, and the exterior-facing surface 62 is provided with an AT material 68 that abuts against the interior surface 3B of the panel 3. The inner peripheral surface 63 and the outer peripheral surface 64 are continuous with the exterior-facing surface 62 and the interior-facing surface 65, and the inner peripheral surface 63 is positioned on the inner peripheral side of the frame relative to the outer peripheral surface 64 and defines the opening 7. The first engagement portion 66 has an engagement piece portion 661 extending from the portion of the outer surface portion 64 that is continuous with the exterior visible surface portion 62 toward the outer periphery of the frame, and a claw portion 662 formed at the tip of the engagement piece portion 661. The second engagement portion 67 is positioned closer to the interior side of the room than the first engagement portion 66, and has a base piece portion 671 extending from the portion of the outer surface portion 64 that is continuous with the interior-facing surface portion 65 toward the outer periphery of the frame, a step portion 672 bent from the base piece portion 671 toward the outside of the room, and an end piece portion 673 extending from the step portion 672 toward the outer periphery of the frame. The indoor piece 70 has an outer end that is continuous with the part where the inner peripheral surface 63 and the indoor visible surface 65 are continuous, and is inclined relatively toward the outer periphery of the frame with respect to the direction along the inner peripheral surface 63. The indoor piece 70 is fastened to the building skeleton 5 with screws.

[0016] The state in which the resin frame members 60A, 60B, and 60C are attached to the upper metal frame member 21, the lower metal frame member 31, and the left and right vertical metal frame members 41 will be described below. The upper metal frame material 21, the lower metal frame material 31 and the left and right vertical metal frame materials 41 are framed vertically, and the resin frame materials 60A, 60B and the left and right resin frame materials 60C are framed horizontally. In the upper frame 20, when the first engaging portion 66 and the second engaging portion 67 of the resin frame material 60A are engaged with the first horizontal engaged portion 51 and the second horizontal engaged portion 55 of the upper metal frame material 21 as shown in Figure 2, the inner surface portion 63 of the resin frame material 60A is positioned at an angle toward the outer periphery of the frame in the Z-axis direction so that the position of its outer end is higher than the position of the indoor half portion 70 of the resin frame material 60A, and both ends in the X-axis direction of the indoor half portion 70 of the upper frame 20 abut the upper end surfaces in the Y-axis direction of the indoor half portions 70 of the left and right vertical frames 40A, 40B. 5, when the first engaging portion 66 and the second engaging portion 67 of the resin frame member 60B are engaged with the first horizontal engaged portion 51 and the second horizontal engaged portion 55 of the lower metal frame member 31, the inner peripheral surface portion 63 is inclined toward the outer periphery of the frame with respect to the Z-axis direction so that its outer end is located lower than the position of the indoor half portion 70 of the resin frame member 60B. Both ends of the indoor half portion 70 of the lower frame 30 in the X-axis direction abut the lower end surfaces of the indoor half portions 70 of the left and right vertical frames 40A, 40B in the Y-axis direction. A gap 80 is formed between the inner peripheral surface portion 63 of the resin frame member 60B and the lower end surfaces of the main body portions 61 of the left and right resin frame members 60C in the Y-axis direction. In the vertical frame 40A, when the first engaging portion 66 and the second engaging portion 67 of the resin frame material 60C are engaged with the first vertical engaged portion 46 and the second vertical engaged portion 47 of the vertical metal frame material 41 as shown in Fig. 4, the indoor piece portion 70 is arranged at an angle toward the outer periphery of the frame with respect to the projection direction of the fixture so that the position of its indoor end is on the outer periphery to the left and right (left side in the vertical frame 40A shown in Fig. 4) of the position of the inner periphery portion 63 of the resin frame material 60C. Note that in the vertical frame 40B, the arrangement is left and right reversed compared to the arrangement in the vertical frame 40A.

[0017] Here, the dimension in the Y-axis direction of the lower metal frame material 31 between position P1 where it abuts against the first engagement portion 66 of the resin frame material 60B and position P2 where it abuts against the second engagement portion 67 is larger than the dimension in the X-axis direction of the vertical metal frame material 41 between position P3 where it abuts against the first engagement portion 66 of the resin frame material 60C and position P4 where it abuts against the second engagement portion. Furthermore, by forming a gap 80 (see FIG. 5) between the main body 61 of the resin frame material 60B and the main body 61 of the left and right resin frame materials 60C, the drainage path 90 shown in FIGS. 6(A) and 6(B) can be formed using the gap 80, and the slope of the inner peripheral surface 63 of the resin frame material 60B can be used as a water gradient, allowing condensation and other water to be drained through the drainage path 90. The drainage path 90 runs from the inner peripheral surface 63 of the resin frame material 60B through the gap 80, along the continuous portion 36, rising surface portion 34, and bottom surface 33 of the lower metal frame material 31, and drains water to the outside through drainage openings 331 (see FIG. 6(B)) formed on both the left and right ends of the bottom surface 33.

[0018] [Variations] In the above embodiment, the resin frame material 60 includes a main body portion 61 having an inner peripheral surface portion 63 and an indoor section portion 70 extending from the main body portion 61 toward the interior of the room and inclined relative to the inner peripheral surface portion 63. The inner peripheral surface portion 63 of the lower frame 30 is inclined toward the outer periphery of the frame with respect to the Z direction so that its outer edge is located lower than the indoor section portion 70 of the lower frame 30. However, this is not limited to this. For example, the resin frame material 60 may include a main body portion 61 having an inner peripheral surface portion 63 and an indoor section portion 70 extending from the main body portion 61 toward the interior of the room and being flat without inclining relative to the inner peripheral surface portion 63, and the inner peripheral surface portion 63 and the indoor section portion 70 of the lower frame 30 may be arranged along the Z direction. Even in this case, the indoor section portions 70 of the vertical frames 40A, 40B and the indoor section portion 70 of the lower frame 30 are configured to abut against each other, reducing the risk of noticeable gaps being formed between these indoor sections 70. In the above embodiment, the resin frame material 60 is configured as a pressing edge, but if the indoor surface 3B of the panel 3 is pressed down with a metal frame material, it does not have to be configured as a pressing edge that presses down the indoor surface 3B. In the above embodiment, the gap 80 is used as part of the drainage path 90, so there is no need to take the trouble of sealing the gap 80. However, if another drainage path is to be created, the gap 80 may be sealed with a sealing material or the like, or may be sealed by processing the resin frame material 60C along the slope of the inner surface portion 63 of the resin frame material 60B. In the above embodiment, a fixed window is used as the fixture, but various modifications and additions are possible without departing from the gist of the present invention, and other window types may also be used as the fixture.

[0019] [Summary of the invention] The building fixture of the present invention is a building fixture comprising a frame body having an upper frame, a lower frame, and left and right vertical frames, and a surface material placed within the frame body, wherein the upper frame, the lower frame, and the left and right vertical frames each comprise a metal frame material on the outside of the room and a resin frame material on the inside of the room that is attached to the metal frame material, the resin frame materials in the upper frame, the lower frame, and the left and right vertical frames each have the same cross-sectional shape along a direction perpendicular to their longitudinal direction, the resin frame material has a main body portion with an inner surface portion, and an interior piece portion extending from the main body portion toward the interior of the room, the interior piece portions in the left and right vertical frames are positioned so that the positions of their interior ends are on the left and right outer sides of the positions of the inner surface portions in the left and right vertical frames, and the interior piece portions in the upper frame and the lower frame abut against the interior piece portions in the left and right vertical frames. According to the building fixture of the present invention, by tilting the interior piece portions of the left and right vertical frames as described above, the interior piece portions can be positioned so that they are pressed against the building opening, compared to the gap between the upper or lower frame and the building opening, and the gap between the interior piece portions and the building main body can be eliminated, thereby making it possible to create a configuration in which the gap between the left and right vertical frames and the building main body, which is easily visible from inside the room, is less noticeable. In addition, by making the cross-sectional shapes of the resin frame materials for the upper frame, lower frame, and left and right vertical frames the same, the number of shaped materials can be reduced, thereby reducing costs, compared to using resin frame materials with different cross-sectional shapes for the upper frame, lower frame, and left and right vertical frames.

[0020] In the fitting of the present invention, the resin frame material may be formed so that the interior piece portion is flat relative to the inner surface portion. With this configuration, the flat-formed resin frame material appears to be connected to the surface material in a continuous manner from the building opening, such as a picture frame, without any gaps or steps, further improving the interior design.

[0021] In the building fixture of the present invention, the resin frame material may be formed so that the indoor piece portion is inclined relative to the inner surface portion, and the inner surface portion of the lower frame may be positioned so that the position of its outdoor end is lower than the position of the indoor piece portion of the lower frame. With this configuration, even when using a resin frame material in which the interior half is inclined relative to the inner peripheral surface and the cross-sectional shape is the same on all four sides, by inclining the inner peripheral surface of the lower frame as described above, the interior edge of the interior half of the lower frame can be set at the same height as or higher than the interior edge of the inner peripheral surface, allowing the interior half of the lower frame to abut against the interior half of the left and right vertical frames, reducing the risk of gaps being formed between them that would be noticeable from the inside of the room. Furthermore, by inclining the inner peripheral surface of the lower frame as described above, a water gradient is created that directs water to the outside of the room, preventing condensation water from flowing down the surface material, such as glass panels, from flowing inside the room. This allows water to be drained without the need for steps on the inner peripheral surface or the interior half, resulting in a fitting that is excellent in design and cleanability.

[0022] In the building fixture of the present invention, the resin frame material is configured as a pressing edge that holds down the interior surface of the face material, and a gap may be formed between the main body portion of the vertical frame and the main body portion of the lower frame. With this configuration, the aforementioned gap can be used as a drainage path for condensation water, etc., and if the indoor piece portion of the aforementioned resin frame material is formed in a shape that is inclined relative to the inner surface portion, condensation water, etc. that is guided by the aforementioned water gradient can be drained through the aforementioned gap. Furthermore, if the inner peripheral surface and the interior half of the resin frame material are both flat, providing a step on the inner peripheral surface or the interior half can form the gap described above and allow drainage. Furthermore, even if the above-mentioned gap is formed, the indoor portions of the vertical frame and the upper and lower frames abut against each other at least at the indoor end side, so the gap is not easily noticeable from the inside of the room.

[0023] In the building fixture of the present invention, the metal frame material may have an exterior-facing surface portion that abuts the exterior surface of the face material, and the resin frame material may be configured as a pressing edge that holds down the interior surface of the face material. With this configuration, a fixed window can be formed in which the panel is held by the metal frame material and resin frame material in the upper frame, lower frame, and left and right vertical frames.
