Description

Technical Field

[0001] The present invention relates to a fitting in which an openable / closable door body is disposed at an opening of a frame body.

Background Art

[0002] In a fitting comprising a frame body and a door body, the door body is disposed at an opening of the frame body and is openably / closably connected to the frame body. The door body is disposed between an outdoor space and an indoor space of a building, and the opening of the frame body is opened and closed by the door body. Regarding the performance of such fittings, thermal insulation performance is important from the perspective of energy saving and the like, and further improvement of thermal insulation performance is demanded. In response to this, heat insulating fittings in which a plurality of exterior panels are arranged side by side on the outdoor side of the door body have been conventionally known (see Patent Document 1).

[0003] In the conventional heat insulating fitting described in Patent Document 1, the exterior panel includes a decorated steel plate and a heat insulating material, and is fixed to the door body with a fixing screw. The decorated steel plate is formed into a hollow rectangular cylindrical shape, and the heat insulating material is accommodated inside the decorated steel plate. However, the plurality of exterior panels are arranged at regular intervals and are arranged from the door body to a position on the outdoor side relative to the frame body. Accordingly, the door body is exposed to the outdoor side through the gaps between the plurality of exterior panels, and the area of the plurality of exterior panels exposed to outside air also increases. Therefore, in conventional heat insulating fittings, in addition to direct heat transfer between the door body and the outside air, there is a risk that heat transfer between the door body and the outside air via the plurality of exterior panels also increases, and there is concern that this will affect the thermal insulation performance.

[0008] [Figure 1] This is a front view showing the joinery as seen from the outside of this embodiment. [Figure 2] This is a front view showing the joinery as seen from the indoor side of this embodiment. [Figure 3] Figure 2 is a longitudinal cross-sectional view showing the joinery and building of this embodiment, cut along the line X1-X1. [Figure 4] Figure 2 is a cross-sectional view showing the joinery and building of this embodiment, cut along the line X2-X2. [Modes for carrying out the invention]

[0009] One embodiment of the building component of the present invention will be described with reference to the drawings. The fixture in this embodiment is an openable and closable door, installed in an opening in a building. Furthermore, the fixture is installed between the interior and exterior of a building, closing off the opening. The following description will use the example of a front door installed at an entrance to explain the fixture in this embodiment.

[0010] Figure 1 is a front view of the door / window 1 as seen from the outside in this embodiment, and Figure 2 is a front view of the door / window 1 as seen from the inside in this embodiment. Figures 1 and 2 show the schematic configuration of the door / window 1 as seen from the front when installed in building 2. As shown in the diagram, joinery 1 is a renovated joinery (renovated door) that was created by replacing an existing joinery installed in building 2 with a new joinery. Joinery 1 is a single-leaf door and is installed in the entrance opening 2A of building 2. Existing joinery is the existing door, and new joinery is a new door used for the renovation of the existing joinery.

[0011] When the joinery 1 installed in building 2 is viewed from the front, the up-and-down direction is the vertical direction R, and the left-and-right direction is the left-and-right direction S. In Figures 1 and 2, the up-and-down direction R is the vertical direction, and the left-and-right direction S is the horizontal direction. The indoor / outdoor direction is the indoor / outdoor direction (indoor / outdoor direction) of the joinery 1 installed in building 2. Furthermore, the indoor / outdoor direction is the front-and-back direction (depth direction) and the thickness direction of the joinery 1 when the joinery 1 installed in building 2 is viewed from the front, and in Figures 1 and 2, it is the horizontal direction perpendicular to the left-and-right direction S. Thus, the direction related to joinery 1 is specified by the direction when joinery 1 is installed in building 2. Also, the indoor side and outdoor side of joinery 1 are the indoor side and outdoor side when it is installed in building 2.

[0012] The joinery 1 comprises an existing frame 10 of the existing joinery (shown by a dashed line in Figure 2), a frame 3 and an openable / closable door 4 provided for the new joinery for renovation. Frame 3 is a new frame for renovation that replaces the existing frame 10, and covers the existing frame 10 installed in building 2. Frame 3 is a rectangular opening frame (door frame) and is installed in the opening 2A of building 2, surrounding the door 4. Door 4 is a new door for renovation that opens and closes by rotation, and is positioned in the opening 3A of frame 3, which is the new frame. Door 4 is connected to frame 3 by multiple hinges 4A so as to be openable and closable, and rotates around the pivot axis of the hinges 4A. Door 4 opens and closes by rotating toward the outside side and toward frame 3 side (indoor side).

[0013] The door body 4 has a door closer 4B located at the top of the door body 4, and a handle 4C and a locking device 4D located on the leading edge side of the door body 4.

The door closer 4B is attached to the door body 4 and the frame 3 to adjust the closing speed of the door body 4. The handle 4C is an operating device for opening and closing the door body 4. The door body 4 is opened and closed using the handle 4C, and when closed, it is locked by the locking device 4D.

[0014] When opening and closing, the door body 4 rotates toward the outside to open and rotates toward the frame body 3 to close. The door body 4 rotates in the opening direction from the closed position inside the opening 3A of the frame body 3 toward the open position on the outside to open and is positioned in the open position. The door body 4 also rotates in the closing direction from the open position toward the closed position on the frame body 3 to close and is positioned in the closed position. The closed position of the door body 4 is the position where the door body 4 is positioned when it is closed (fully closed position), and the open position of the door body 4 is the position where the door body 4 is positioned when it is opened (fully open position). The door body 4 opens and closes by moving between the closed position and the open position through rotation. The opening 3A of the frame body 3 is opened and closed by the opening and closing door body 4.

[0015] Frame 3 has four frames 5-8 (upper frame 5, lower frame 6, and a pair of vertical frames 7 and 8) that are combined with each other.

The opening 3A of frame 3 is formed in a rectangular shape by frames 5-8 of frame 3 and is located inside frame 3. The opening 3A and the door 4 of frame 3 are surrounded by frames 5-8 of frame 3. The longitudinal direction of frames 5-8 of frame 3 is the direction in which each of frames 5-8 extends (extension direction). The longitudinal direction of the upper frame 5 and lower frame 6 is the left-right direction S, and the longitudinal direction of the vertical frames 7 and 8 is the up-down direction R.

[0016] The upper frame 5 and the lower frame 6 are upper and lower horizontal frames (upper horizontal frame, lower horizontal frame) located at the upper portion and the lower portion of the frame body 3, respectively, and extend in the horizontal direction (left-right direction S). A pair of vertical frames 7 and 8 (first vertical frame 7, second vertical frame 8) are side frames located at the left and right side portions of the frame body 3, respectively, and extend in the vertical direction (vertical direction R). The ends of the upper frame 5, the lower frame 6, and the left and right vertical frames 7 and 8 are connected to each other and arranged in a rectangular shape. The door body 4 is connected to the second vertical frame 8, which is one of the left and right vertical frames 7 and 8, by a hinge 4A.

[0017] Figure 3 is a longitudinal sectional view showing the fitting 1 of the present embodiment and the building 2 cut along the line X1-X1 in Figure 2, and shows the fitting 1 and the building 2 cut along a plane including the vertical direction R and the indoor-outdoor direction T. Figure 4 is a cross-sectional view showing the fitting 1 of the present embodiment and the building 2 cut along the line X2-X2 in Figure 2, and shows the fitting 1 and the building 2 cut along a plane including the left-right direction S and the indoor-outdoor direction T.

[0024] The outdoor-side projection sections 5B to 8B are positioned further outward (on the outer periphery of the frame 3) from the opening 3A of the frame 3 than the indoor-side projection sections 5C to 8C. The indoor-side projection sections 5C to 8C are positioned further inward (towards the center of the opening 3A) from the opening 3A of the frame 3 than the outdoor-side projection sections 5B to 8B. The support members 5D to 8D and the mounting sections 5E to 8E are the intermediate sections and stepped sections provided in the projection sections of frames 5 to 8 of the frame 3, and are located between the outdoor-side projection sections 5B to 8B and the indoor-side projection sections 5C to 8C. The outdoor-side projection sections 5B to 8B, the indoor-side projection sections 5C to 8C, and the support members 5D to 8D face the opening 3A of the frame 3.

[0025] The frame 3 has an inner circumference 3B facing the opening 3A. The inner circumference 3B is the part of the frame 3 that surrounds the opening 3A (enclosing part) and is located on the inner circumference of the frame 3. The inner circumference 3B is also composed of the parts of the frame 3 (upper frame 5, lower frame 6, left and right vertical frames 7 and 8) that face the opening 3A and is located above, below, to the left and right of the door body 4. The rectangular opening 3A is demarcated by the rectangular inner circumference 3B. In the opening 3A of the frame 3, the door body 4 is connected to the inner circumference 3B so as to be openable and closable, and is enclosed by the inner circumference 3B.

[0026] The outdoor-side projections 5B to 8B and indoor-side projections 5C to 8C of frames 5 to 8 are located on the inner circumference 3B of frame 3 and constitute the inner circumference 3B of frame 3. The outdoor-side projections 5B and indoor-side projections 5C of upper frame 5 are at the top of the inner circumference 3B and are located above the opening 3A and door body 4. The outdoor-side projections 6B and indoor-side projections 6C of lower frame 6 are at the bottom of the inner circumference 3B and are located below the opening 3A and door body 4. The outdoor-side projections 7B and 8B and indoor-side projections 7C and 8C of left and right vertical frames 7 and 8 are the left and right sides of the inner circumference 3B and are located to the left and right sides of the opening 3A and door body 4.

The outer perimeter 21 of the door body 20 is positioned opposite the outer perimeter 3C of the inner perimeter 3B and the outdoor-side projections 5B to 8B of the frames 5 to 8, with a gap between them. The outer perimeter 31 of the insulation panel 30 is positioned opposite the indoor-side inner perimeter 3D of the inner perimeter 3B and the indoor-side projections 5C to 8C of the frames 5 to 8, with a gap between them.

[0036] The door body 20 has four interlocking frame members 22-25 (upper frame member 22, lower frame member 23, and a pair of vertical frame members 24, 25), an insulating material 26 surrounded by the frame members 22-25, and a pair of surface materials 27, 28 (first surface material 27, second surface material 28) that cover the surface of the door body 20. The upper frame member 22 and the lower frame member 23 are upper and lower horizontal frame members located at the top and bottom of the door body 20 and extend in the horizontal direction. The pair of vertical frame members 24, 25 (first vertical frame member 24, second vertical frame member 25) are side frame members located on the left and right sides of the door body 20 and extend in the vertical direction. The upper frame member 22, the lower frame member 23, and the left and right vertical frame members 24, 25 are connected at their ends and arranged in a rectangular shape.

[0037] The structural members 22-25 and the insulation material 26 are provided in the inner space of the door body 20, which is surrounded by a pair of surface materials 27 and 28, and are positioned between the pair of surface materials 27 and 28, sandwiched between them. The structural members 22-25 extend along the outer periphery 21 of the door body 20. The insulation material 26 is, for example, a resin foam such as urethane foam, and is positioned inside the rectangularly arranged structural members 22-25. The pair of surface materials 27 and 28 are plate materials located on the surface of the door body 20, and they sandwich the structural members 22-25 and the insulation material 26 between them, covering the entire structural members 22-25 and the insulation material 26.

[0038] The first surface material 27 is an outdoor surface material located on the outdoor side of the surface of the door body 20, and is located on the outdoor side and the outer perimeter 21 side relative to the frame materials 22-25 and the insulation material 26. The second surface material 28 is an indoor surface material located on the indoor side of the surface of the door body 20, and is located on the indoor side and the outer perimeter 21 side relative to the frame materials 22-25 and the insulation material 26.

[0039] The first surface material 27 is located on the front surface of the door body 20 facing outdoors, and bends inwards from the front surface facing outdoors toward the outer perimeter 21 of the door body 20, and is located on the outdoor side of the outer perimeter 21. The second surface material 28 is located on the front surface of the door body 20 facing indoors, and bends inwards from the front surface facing indoors toward the outer perimeter 21 of the door body 20, and is located on the indoor side of the outer perimeter 21.

[0040] The insulation panel 30 has an insulation material 32 and a surface material 33 that covers the surface of the insulation panel 30. The insulation material 32 is, for example, a resin foam such as urethane foam, and is provided in the inner space of the insulation panel 30 surrounded by the surface material 33. The surface material 33 is a plate material located on the surface of the insulation panel 30 and covers the insulation material 32. On the surface of the insulation panel 30, the surface material 33 is located on the indoor side front part and bends outward from the indoor side front part toward the outer perimeter 31 of the insulation panel 30, and is located on the entire outer perimeter 31.

[0041] The surface material 33 of the insulation panel 30 is located on the indoor side and on the outer perimeter 31 side of the insulation panel 30 relative to the insulation material 32, covering the insulation material 32 on both the indoor and outer perimeter 31 sides. In contrast, the surface material 33 is not provided on the outdoor side of the insulation material 32. Therefore, on the outdoor side, the insulation material 32 is exposed to the outside of the insulation panel 30 without being covered by the surface material 33. The outdoor side of the insulation material 32 and the outdoor end of the surface material 33 are the outdoor front part of the insulation panel 30 and are positioned opposite the indoor side of the second surface material 28, which is the indoor front part of the door body 20.

In this way, the first mounting member 40 attaches the insulation panel 30 to the frame of the door body 20 (in this case, the upper frame 22), and holds the insulation panel 30 to the upper frame 22. The insulation panel 30 is connected to the upper frame 22 and the door body 20 via the first mounting member 40.

[0044] The second mounting member 41 is positioned on the left and right sides of the insulation panel 30, between the insulation material 32 and the surface material 33, and is fixed to the surface material 33 by a third fastener 46, which is a screw. The second mounting member 41 is also located on the indoor side of the door body 20, on the left and right sides of the door body 20, on the indoor side of the second surface material 28, and is fixed to the second surface material 28 by a fourth fastener 47, which is a rivet. In this way, the second mounting member 41 attaches the insulation panel 30 to the surface material (in this case, the second surface material 28) of the door body 20 and holds the insulation panel 30 to the second surface material 28. The insulation panel 30 is connected to the second surface material 28 and the door body 20 via the second mounting member 41.

[0045] The insulation panel 30 is positioned with a gap between it and the door body 20 in the indoor-outdoor direction T. The air layer 42 of the door body 4 is the gap formed between the door body 20 (indoor front part) and the insulation panel 30 (outdoor front part), and is partitioned by the door body 20 and the insulation panel 30. The door body 20 is located on the outdoor side of the air layer 42, and the insulation panel 30 is located on the indoor side of the air layer 42. In the indoor-outdoor direction T, the door body 20 and the insulation panel 30 face each other with the air layer 42 in between, and each faces the air layer 42.

[0046] The cushioning material 43 of the door body 4 is an elastically deformable spacer (e.g., sponge, foam, elastic material) and is attached by adhesive to at least one of the door body 20 and the insulation panel 30. The cushioning material 43 is sandwiched between the door body 20 (indoor front part) and the insulation panel 30 (outdoor front part) at the bottom of the insulation panel 30, and is compressed and elastically deformed between the door body 20 and the insulation panel 30. The cushioning material 43 is also located below the air gap 42 and seals the lower part of the air gap 42. The cushioning material 43 maintains the gap between the door body 20 and the insulation panel 30, ensuring the air gap 42 is maintained.

[0047] Here, the insulation material 32 of the insulation panel 30 is positioned with a gap between it and the second surface material 28 of the door body 20. The air layer 42 is the gap formed between the second surface material 28 of the door body 20 and the insulation material 32 of the insulation panel 30, and is provided between the second surface material 28 of the door body 20 and the insulation material 32 of the insulation panel 30. In addition, the buffer material 43 is sandwiched between the second surface material 28 of the door body 20 and the insulation material 32 of the insulation panel 30 and is positioned along the lower edge of the insulation panel 30 (outdoor front part).

[0048] In the joinery 1 described above, the thickness of the door body 4 can be increased by the insulation panel 30, thereby suppressing heat transfer through the door body 4 between the indoor space 2B and the outdoor space 2C. Furthermore, by installing the insulation panel 30 on the indoor side of the door body 20, the insulation panel 30 is not exposed to the outside air (air from the outdoor space 2C), and the insulation function of the insulation panel 30 can be effectively exerted at the opening 3A (indoor opening 3F) of the frame 3 located on the indoor side of the door body 20. Therefore, the insulation performance of the joinery 1 can be easily improved.

[0049] The insulation panel 30 makes it easy to improve the insulation performance of the remodeled door. In addition, the air layer 42 inside the door body 4 suppresses heat transfer between the door body 20 and the insulation panel 30, thereby improving the insulation performance of the door body 4. The insulation panel 30 can be stably attached to the door body 20 by attaching it to the upper frame 22 of the door body 20 with the first mounting material 40.

[0050] The outer perimeter 31 of the insulation panel 30 and the inner perimeter 3B (indoor inner perimeter 3D) of the frame 3 face each other with a gap between them. Therefore, on the indoor side of the door body 20, the insulation panel 30 can suppress heat transfer between the inner perimeter 3B of the frame 3 and the indoor space 2B. In addition, an air layer can be formed between the inner perimeter 3B of the frame 3 and the outer perimeter 31 of the insulation panel 30. Therefore, the thermal insulation performance of the door 1 can be improved.

[0051] The upper part and left and right sides of the insulation panel 30 are attached to the door body 20 by mounting materials 40 and 41. Alternatively, the upper and lower parts of the insulation panel 30 may be attached to the door body 20 by mounting materials. In this case, the upper part of the insulation panel 30 is attached to the upper frame 22 of the door body 20, and the lower part of the insulation panel 30 is attached to the lower frame 23 or the second surface material 28 of the door body 20. Alternatively, the left and right sides of the insulation panel 30 may be attached to the door body 20 by mounting materials. In this case, the left and right sides of the insulation panel 30 are attached to the vertical frame 24 and 25 of the door body 20, respectively.

[0052] In addition to the surface material 33 of the insulation panel 30, a surface material may also be provided on the outdoor side of the insulation material 32, so that the entire insulation material 32 and the entire surface of the insulation panel 30 are covered with the surface material. The present invention is not limited to renovated joinery, but can be applied to various joinery equipped with a frame and a door, such as joinery newly installed in a building.
