Description

[Technical field]

[0001] The present disclosure relates to a support fitting, a support structure, and a building in an opening where a building fixture is installed. [Background technology]

[0002] A building has fittings such as doors, shutters, and windows. The fittings are installed in openings in walls. The openings are composed of multiple members. The openings have an upper frame material. The upper frame material is connected to a beam above the upper frame material by connecting members. The connecting members support the upper frame material. If the beams bend, there is a risk that the upper frame material will also bend via the connecting members. Patent Document 1 discloses a support structure for suppressing bending of the upper frame material due to bending of the beams. The support structure in this document is composed of a girth, a lintel, and architectural hardware that connects the girth and the lintel. The architectural hardware is configured so that its vertical dimensions change according to dimensional changes between the girth and the lintel. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-008833 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the technology of Patent Document 1, there is a risk that the support structure may deform due to horizontal force or lateral shaking. If the upper frame material in the support structure shifts laterally relative to the beam, the movement of the fixtures is hindered. For this reason, there is room for improvement in the support fittings, support structure, and buildings. [Means for solving the problem]

[0005] (1) The support metal fitting that solves the above problem is arranged between an upper frame member of an opening where a door is to be installed and a horizontal member extending above the upper frame member, and is connected to the upper frame member and the horizontal member, and is configured to elastically deform in the vertical direction and have a higher rigidity in a second direction along the width direction of the horizontal member than in a first direction along the longitudinal direction of the horizontal member. With this configuration, the support metal fitting is arranged between the upper frame member and the horizontal member and joined to both members, and the support metal fitting deforms according to the deflection of the horizontal member, thereby suppressing deformation of the upper frame member. Furthermore, compared to a rod-shaped support member, the upper frame member can be prevented from shifting relative to the horizontal member due to a force in the width direction of the horizontal member. Examples of forces in the width direction of the horizontal member include wind pressure due to a typhoon, vibrations due to an earthquake, and water pressure due to flooding.

[0006] (2) The support fitting of (1) above includes a first fixing part fixed to the cross member, a second fixing part fixed to the upper frame member, and a spring part connecting the first fixing part and the second fixing part, the spring part being configured to elastically deform in the vertical direction and to have a greater rigidity in the second direction than in the first direction. With this configuration, the support fitting has a simple structure and is easy to manufacture.

[0007] (3) In the support fitting of the above (2), the spring portion has two leaf springs, and when the support fitting is disposed between the cross member and the upper frame member, the two leaf springs are aligned along the first direction. With this configuration, when the support fitting is disposed between the upper frame member and the cross member and joined to both members, it is possible to improve the support strength of the upper frame member.

[0008] (4) In the support fitting of the above (3), the two leaf springs are curved in opposite directions to each other and protrude in the first direction so that the gap between the two leaf springs is widest at the middle in the up-down direction. With this configuration, interference between the two leaf springs can be avoided.

[0009] (5) In the support fitting of (2) above, the spring portion has a leaf spring, and the leaf spring is configured so that the width direction of the leaf spring is along the second direction when the support fitting is disposed between the cross member and the upper frame member. With this configuration, when the support fitting is disposed between the upper frame member and the cross member and connected to both members, it is possible to suppress the occurrence of slippage of the upper frame member relative to the cross member in the second direction.

[0010] (6) In the support fitting of the above (2), the spring portion is composed of a plurality of coil springs, and when the support fitting is disposed between the cross member and the upper frame member, the plurality of coil springs are arranged along the second direction. With this configuration, the support fitting has a simple structure and is easy to manufacture.

[0011] (7) In the support fitting of any one of (2) to (6) above, the first fixing portion includes a first plate and a first pole configured to be inserted into a first mortise of the cross member and protruding from the first plate, and the second fixing portion includes a second plate and a second pole configured to be inserted into a second mortise of the upper frame member and protruding from the second plate. With this configuration, the support fitting can be easily fixed to the cross member and the upper frame member.

[0012] (8) A support structure that solves the above problems includes an upper frame member of an opening where a fixture is to be installed, a horizontal member extending above the upper frame member, and any one of the support fittings (1) to (7) above. With this configuration, the support fittings deform in response to bending of the horizontal member, so deformation of the upper frame member can be suppressed. Also, deformation of the opening against force in the width direction of the horizontal member can be suppressed.

[0013] (9) In the support structure of (8) above, a plurality of support members are disposed between the upper frame member and the cross member along the longitudinal direction of the cross member, and at least one of the support members is the support fitting. With this configuration, the support fitting can suppress deformation of the opening.

[0014] (10) A building that solves the above problem includes the support structure of (9). With this configuration, deformation of the opening of the building can be suppressed. Effect of the Invention

[0015] The support fittings, support structure, and building disclosed herein can suppress deformation of the opening due to bending of the cross members and due to horizontal forces or lateral swaying. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] The support fitting 1, the support structure 2 and the building 3 will be described with reference to Figs. 1 to 7. 1 and 2, a building 3 has fittings 4 such as doors, windows, and the like. The fittings 4 are provided in openings 5. In this embodiment, an example of the fittings 4 is a window provided in an exterior wall. An example of the opening 5 is an opening in the exterior wall to which the window is attached.

[0018] The building 3 has a support structure 2 at the opening 5. In this embodiment, the support structure 2 refers to a support structure for an upper frame member 6 of the opening 5 relative to a cross member 7. Examples of the building 3 include facilities such as a detached house, an apartment building, a community center, and a kindergarten. In this embodiment, the building 3 is a detached house.

[0019] The support structure 2 includes an upper frame member 6 of the opening 5, a horizontal member 7 extending above the upper frame member 6, and a support bracket 1. The horizontal member 7 is a member that constitutes the framework. The horizontal member 7 includes girder 7A, beams, girders, and roof beams.

[0020] In this embodiment, the opening 5 is provided under a girder 7A serving as a cross member 7. A sweep window 4A is provided in the opening 5. The sweep window 4A includes a sash and a window body. The sash of the sweep window 4A is fixed to the opening 5. The upper frame material 6 of the opening 5 is also called a lintel 6A.

[0021] In this embodiment, the support structure 2 includes a lintel 6A located above the sweep window 4A, a girth 7A extending above the lintel 6A, and a support bracket 1. Between the lintel 6A and the girth 7A, a plurality of support members 1X are arranged along the longitudinal direction of the girth 7A.

[0022] Examples of the support member 1X include a bundle and a support fitting 1. At least one of the support members 1X is a support fitting 1. In this embodiment, all of the multiple support members 1X are support fittings 1.

[0023] <Support bracket> 2 and 3, the support fitting 1 is disposed between the lintel 6A of the opening 5 and the girth 7A extending above the lintel 6A. The support fitting 1 is connected to the lintel 6A and the girth 7A. In this embodiment, the support fitting 1 includes a first fixing portion 8 fixed to the girth 7A, a second fixing portion 9 fixed to the lintel 6A, and a spring portion 10 connecting the first fixing portion 8 and the second fixing portion 9.

[0024] The spring portion 10 is configured to elastically deform in the vertical direction. The spring portion 10 is configured to elastically deform in the vertical direction in response to a change in the distance between the lintel 6A and the girth 7A. The spring portion 10 is further configured to have a greater rigidity in the second direction DB than in the first direction DA. The first direction DA and the second direction DB of the support bracket 1 are defined as follows when the support bracket 1 is disposed between the lintel 6A and the girth 7A. The first direction DA is a direction along the longitudinal direction of the girth 7A. The second direction DB is a direction along the width direction of the girth 7A. In this embodiment, the spring portion 10 has two leaf springs 10A. The two leaf springs 10A are connected to each other at the bottom. Each of the two leaf springs 10A is configured as a part of one member. The two leaf springs 10A may be configured as separate members. Examples of materials for the leaf springs 10A include carbon steel, stainless steel, and nickel alloy. The leaf spring 10A of the present embodiment is made of stainless steel.

[0025] The two leaf springs 10A are arranged along the first direction DA in a state where the support bracket 1 is disposed between the girth 7A and the lintel 6A. The leaf springs 10A are configured so that the width direction of the leaf springs 10A is along the second direction DB. The two leaf springs 10A are curved so that they protrude in opposite directions and in the first direction DA, so that the gap between the two leaf springs 10A is widest at the middle portion 11 in the up-down direction.

[0026] 3 and 4, the first fixing portion 8 of the support fitting 1 includes a first plate 12 and a first pole 13 protruding from the first plate 12. The first pole 13 is configured to be inserted into a first mortise 14 of the girth 7A. The second fixing portion 9 of the support fitting 1 includes a second plate 15 and a second pole 16 protruding from the second plate 15. The second pole 16 is configured to be inserted into a second mortise 17 of the lintel 6A.

[0027] The first pole 13 is fixed to the girth 7A by a first pin 18. In this embodiment, the first pin 18 is a drift pin. The first pole 13 is provided with a first pin hole 19 for passing the first pin 18 through. When the first pole 13 is inserted into the first mortise 14, the first pin insertion hole 7B of the girth 7A is connected to the first pin hole 19. The first pin 18 is inserted into the first pin insertion hole 7B and the first pin hole 19.

[0028] The second pole 16 is fixed to the lintel 6A by the second pin 20. In this embodiment, the second pin 20 is a drift pin. The second pole 16 is provided with a second pin hole 21 for passing the second pin 20. When the second pole 16 is inserted into the second mortise 17, the second pin insertion hole 6B of the lintel 6A is connected to the second pin hole 21. The second pin 20 is inserted into the second pin insertion hole 6B and the second pin hole 21.

[0029] The leaf spring 10A is configured so that the rigidity of the leaf spring 10A is smaller than the rigidity of the lintel 6A. Specifically, the rigidity of the leaf spring 10A against compression in the vertical direction is smaller than the rigidity against a force that bends the lintel 6A in the vertical direction. This makes it possible to suppress bending of the lintel 6A.

[0030] The plate thickness of the leaf spring 10A is 2 mm or more and 10 mm or less. The vertical height of the leaf spring 10A when the support bracket 1 is disposed between the girth 7A and the lintel 6A (hereinafter, the installed height of the leaf spring 10A) is 100 mm or more and 500 mm or less. The width of the leaf spring 10A along the second direction DB is 120 mm or less.

[0031] The ease of elastic deformation of the leaf spring 10A can be set by changing the material and dimensions of the leaf spring 10A. The structure of the leaf spring 10A is determined based on the rigidity required for the support bracket 1.

[0032] A support structure 2 having a support fitting 1 will be described with reference to Figs. 5 to 7. Figs. 5 and 6 are front views of a comparative support structure to be compared with the support structure 2 of this embodiment. Fig. 7 is a front view of the support structure 2 in a state in which the support fitting 1 is disposed between the girth 7A and the lintel 6A. The deflection of the girth 7A in Figs. 6 and 7 is emphasized so that the deflection is easily visible.

[0033] As shown in Figures 5 and 6, in the comparative support structure, a support member 1Y is placed between the girth 7A and the lintel 6A. The support member 1Y is a beam 22. The beam 22 is a short pillar and has no elasticity. The girth 7A may bend due to a load such as the weight of the roof being applied to it for a long period of time. In this case, the lintel 6A connected to the girth 7A via the beam 22 also bends as the girth 7A bends. When the lintel 6A bends, the opening 5 is deformed. As a result, the movement of the fitting 4 (see Figure 1) is hindered.

[0034] In the longitudinal direction of the girth 7A, the deflection of the girth 7A is greater at the center 7C of the girth 7A than at the ends of the girth 7A.

[0035] As shown in Fig. 7, in the support structure 2 of this embodiment, the support fitting 1 is disposed between the girth 7A and the lintel 6A (see Fig. 2). The support fitting 1 elastically deforms in the vertical direction according to the degree of bending of the girth 7A. Specifically, as shown in Fig. 7, the support fitting 1 below the center portion 7C of the girth 7A deforms more than the support fitting 1 below the end portion of the girth 7A.

[0036] The operation of this embodiment will now be described. The spring portion 10 of the support fitting 1 elastically deforms in the vertical direction in response to changes in the distance between the lintel 6A and the girth 7A. The spring portion 10 of the support fitting 1 is configured so that its rigidity in the second direction DB is greater than its rigidity in the first direction DA.

[0037] Therefore, the support fitting 1 can be elastically deformed in the vertical direction. This allows the support fitting 1 to suppress deformation of the opening 5 against a force along the width direction of the girth 7A. The opening 5 of the fitting 4 receives not only a load from above, but also a force from a direction perpendicular to the plane including the opening 5. For example, the force of the wind pressure of a typhoon is applied to the opening 5 of the fitting 4. At this time, a force along the width direction of the girth 7A is applied to the support fitting 1. If the support fitting 1 is weak in the width direction of the girth 7A, the lintel 6A may shift relative to the girth 7A, causing the opening 5 to deform. In this regard, as described above, the spring portion 10 of the support fitting 1 is configured to have a greater rigidity in the second direction DB than in the first direction DA. Therefore, the support fitting 1 can suppress the lintel 6A from shifting from the girth 7A even when a force along the width direction of the girth 7A, i.e., a force in the second direction DB, is applied.

[0038] In addition, the support fitting 1 has the following effect. It is known that the girth 7A bends downward due to a load over many years. For this reason, the height dimension of the girth 7A is specified for the girth 7A installed on the outer wall having the opening 5 so that the amount of bending due to the bending of the girth 7A in the future falls within a predetermined value. Or, for the girth 7A installed on the outer wall having the opening 5, the length of the girth 7A in the longitudinal direction is specified. Since the height dimension of the girth 7A is specified in this way, there is a design limit to the vertical height of the opening 5 of the outer wall. Also, since the length of the girth 7A is specified, there is a limit to the widthwise length of the opening 5 of the outer wall. In contrast, according to the support structure 2 of this embodiment, the curvature of the girth 7A is allowed. Therefore, the height dimension of the girth 7A can be reduced. Or, the length of the girth 7A in the longitudinal direction can be increased. For this reason, according to the support structure 2 of this embodiment, the vertical height of the opening 5 can be increased. Or, the widthwise length of the opening 5 can be increased.

[0039] The effects of this embodiment will be described. (1) The support fitting 1 is configured to be elastically deformed in the vertical direction. The support fitting 1 is configured to have a higher rigidity in the second direction DB along the width direction of the girth 7A than in the first direction DA along the longitudinal direction of the girth 7A. With this configuration, the support fitting 1 is configured to be elastically deformable in the vertical direction and to have a higher rigidity in the second direction DB. With this configuration, the support fitting 1 is arranged between the lintel 6A and the girth 7A and is connected to both members, and the support fitting 1 deforms according to the bending of the girth 7A, so that the deformation of the lintel 6A can be suppressed. In addition, compared to a rod-shaped support member, the shift of the lintel 6A relative to the girth 7A can be suppressed against the force in the width direction of the girth 7A. Examples of the force in the width direction of the girth 7A include wind pressure due to a typhoon, vibration due to an earthquake, and water pressure due to a flood.

[0040] (2) The support fitting 1 comprises a first fixed portion 8 fixed to the girth 7A, a second fixed portion 9 fixed to the lintel 6A, and a spring portion 10 connecting the first fixed portion 8 and the second fixed portion 9. The spring portion 10 elastically deforms in the vertical direction in response to changes in the distance between the lintel 6A and the girth 7A. The spring portion 10 is configured so that its rigidity in the second direction DB is greater than its rigidity in the first direction DA. With this configuration, the support fitting 1 comprises the spring portion 10. For this reason, the support fitting 1 has a simple structure and is easy to manufacture.

[0041] (3) The spring portion 10 of the support fitting 1 has two leaf springs 10A. The two leaf springs 10A are arranged along the first direction DA. With this configuration, the support fitting 1 can improve the support strength of the lintel 6A when it is disposed between the lintel 6A and the girth 7A and connected to both components. Specifically, compared to when the spring portion 10 has one leaf spring 10A, the lintel 6A is strongly connected to the girth 7A, so the lintel 6A is less likely to vibrate when the fitting 4 is opened or closed. This suppresses deterioration of the lintel 6A, so the fitting 4 can be opened and closed smoothly for a long period of time.

[0042] (4) The two leaf springs 10A are curved in opposite directions to each other and protrude in the first direction DA so that the gap between the two leaf springs 10A is widest at the vertical middle portion 11. According to this configuration, the two leaf springs 10A are curved in opposite directions to each other and protrude in the first direction DA.

[0043] If the two leaf springs 10A were curved in opposite directions and protruded in the first direction DA so that the gap between the two leaf springs 10A was narrowest at the vertical middle portion 11, there is a risk that the two leaf springs 10A may interfere with each other when compressed. In this regard, the above configuration makes it possible to avoid interference between the two leaf springs 10A.

[0044] (5) The leaf spring 10A is configured such that the width direction of the leaf spring 10A is along the second direction DB when the support bracket 1 is disposed between the girth 7A and the lintel 6A. With this configuration, when the support bracket 1 is disposed between the lintel 6A and the girth 7A and is connected to both components, it is possible to suppress the occurrence of misalignment of the lintel 6A with respect to the girth 7A in the second direction DB.

[0045] (6) The first fixing part 8 comprises a first plate 12 and a first pole 13 protruding from the first plate 12. The first pole 13 is configured to be inserted into a first mortise 14 of the girth 7A. The second fixing part 9 comprises a second plate 15 and a second pole 16 protruding from the second plate 15. The second pole 16 is configured to be inserted into a second mortise 17 of the lintel 6A. This configuration makes it easy to fix the support bracket 1 to the girth 7A and the lintel 6A.

[0046] (7) The support structure 2 includes a lintel 6A of the opening 5 in which the sweep window 4A is provided, a girth 7A extending above the lintel 6A, and a support bracket 1. With this configuration, the support bracket 1 deforms in response to the bending of the girth 7A, so deformation of the lintel 6A can be suppressed. In addition, deformation of the opening 5 due to the force of the girth 7A in the width direction can be suppressed.

[0047] (8) In the building 3, a plurality of support members 1X are arranged between the lintel 6A and the girth 7A along the longitudinal direction of the girth 7A. At least one of the support members 1X is a support fitting 1. With this configuration, the support fitting 1 can suppress deformation of the opening 5.

[0048] In this embodiment, all of the multiple support members 1X are support fittings 1. In another example, the support fittings 1 are placed between the lintel 6A and the girth 7A where the amount of bending of the girth 7A is large. And, the bundle as the support member 1X is placed where the amount of bending of the girth 7A is small.

[0049] (9) The building 3 includes a support structure 2. With this configuration, deformation of the opening 5 of the building 3 can be suppressed.

[0050] <Modification> The above embodiment is an example of the form that the support fitting 1, the support structure 2, and the building 3 can take, and is not intended to limit the form. The support fitting 1, the support structure 2, and the building 3 can take a form different from the form exemplified in the above embodiment. One example is a form in which part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. An example of a modified embodiment is shown below.

[0051] As shown in FIG. 8, the spring portion 10 of the support bracket 1 is composed of a plurality of coil springs 10B. When the support bracket 1 is disposed between the girth 7A and the lintel 6A, the plurality of coil springs 10B are arranged along the second direction DB. The plurality of coil springs 10B may be arranged along the first direction DA. The plurality of coil springs 10B may also be arranged in a plurality of rows. In this modification, four coil springs 10B are arranged to connect the first fixed portion 8 and the second fixed portion 9. The four coil springs 10B are arranged in two rows along the second direction DB. The coil springs 10B are configured such that the rigidity in the second direction DB along the width direction of the girth 7A is greater in the support bracket 1 than in the first direction DA along the longitudinal direction of the girth 7A. For example, the multiple coil springs 10B may be arranged on the first plate 12 so that the stiffness in the second direction DB along the width direction of the girth 7A is greater than the stiffness in the first direction DA. Also, the coil springs 10B may be made of different materials. Also, the dimensions of the coil springs 10B may be different.

[0052] According to this configuration, the support fitting 1 includes a plurality of coil springs 10B arranged along the second direction DB. The support fitting 1 has a simple structure and is therefore easy to manufacture.

[0053] In the support structure 2 of this embodiment, the leaf spring 10A of the support bracket 1 arranged on the lintel 6A may be made of different materials depending on the location where the support bracket 1 is arranged.

[0054] In the support structure 2 of this embodiment, the leaf spring 10A of the support bracket 1 arranged on the lintel 6A may be configured to have dimensions different from those of other support brackets 1 depending on the arrangement location of the support bracket 1.

[0055] The support structure 2 may further include an extension member that engages with the support fitting 1. The extension member is disposed between the support fitting 1 and the lintel 6A. The extension member may have a hole through which the first pole 13 of the support fitting 1 is inserted along the longitudinal direction of the extension member. For example, the extension member is a bundle. The length of the support fitting 1 can be adjusted by this bundle.

[0056] The support bracket 1 may be configured so that its elasticity in the vertical direction changes depending on the location of the support bracket 1. For example, the support bracket 1 arranged in the center 7C of the lintel 6A may be configured so that the leaf spring 10A is more easily compressed and deformed than the support bracket 1 arranged at the end of the lintel 6A.

[0057] In this embodiment, the technology relating to the support structure 2 is applied to the lintel 6A of the opening 5 of the French window 4A, but the technology can also be applied to the support structure of the upper frame material 6 of the opening 5 of other fixtures. For example, the support structure 2 can be applied to the support structure of the upper frame material 6 of the opening 5 of a front door. It can also be applied to the support structure of the upper frame material 6 of the opening 5 of a built-in garage shutter.

[0058] This specification discloses the following techniques. [Appendix 1] The support fitting is disposed between an upper frame member of an opening where a fixture is to be installed and a horizontal member extending above the upper frame member, and connects the upper frame member to the horizontal member. The support fitting elastically deforms in the up-down direction. The support fitting is configured so that its rigidity in a second direction along the width direction of the horizontal member is greater than its rigidity in a first direction along the longitudinal direction of the horizontal member.

[0059] [Appendix 2] The support bracket of Appendix 1 includes a first fixing part fixed to the cross member, a second fixing part fixed to the upper frame member, and a spring part connecting the first fixing part and the second fixing part. The spring part is configured to elastically deform in the vertical direction and to have a greater rigidity in the second direction than in the first direction.

[0060] [Appendix 3] In the support fitting of Appendix 2, the spring portion has two leaf springs. When the support fitting is disposed between the cross member and the upper frame member, the two leaf springs are aligned along the first direction.

[0061] [Appendix 4] In the support fitting of Supplementary Note 3, the two leaf springs are curved so as to protrude in opposite directions to each other and in the first direction, so that the gap between the two leaf springs is widest at the middle part in the up-down direction.

[0062] [Appendix 5] In the support fitting of Supplementary Note 2, the spring portion has a leaf spring. When the support fitting is disposed between the cross member and the upper frame member, the leaf spring is configured such that a width direction of the leaf spring is aligned with the second direction.

[0063] [Appendix 6] In the support fitting of Appendix 2, the spring portion is constituted by a plurality of coil springs. When the support fitting is disposed between the cross member and the upper frame member, the plurality of coil springs are aligned along the second direction.

[0064] [Appendix 7] In the support fitting of Appendix 2, the first fixing part includes a first plate and a first pole configured to be inserted into a first mortise of the cross member and protruding from the first plate, and the second fixing part includes a second plate and a second pole configured to be inserted into a second mortise of the upper frame member and protruding from the second plate.

[0065] [Appendix 8] The support structure comprises an upper frame member of an opening where a fixture is to be installed, a cross member extending above the upper frame member, and the support fitting according to any one of Supplementary Notes 1 to 7.

[0066] [Appendix 9] In the support structure of Appendix 8, a plurality of support members are disposed between the upper frame member and the horizontal member along the longitudinal direction of the horizontal member. At least one of the support members is the support metal fitting.
