Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the technique of Patent Document 1, there is a possibility that the support structure may be deformed against a horizontal force or a lateral sway. If the upper frame member in the support structure is laterally displaced with respect to the beam, the movement of the fitting is hindered. Therefore, there is room for improvement in the support fitting, the support structure, and the building.

Means for Solving the Problems

[0005] (1) The support fitting for solving the above problems is disposed between an upper frame member of an opening where the fitting is provided and a horizontal member extending above the upper frame member, and is a support fitting connected to the upper frame member and the horizontal member. It is configured to elastically deform in the vertical direction and have a greater 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. According to this configuration, the support fitting is disposed between the upper frame member and the horizontal member and is coupled to both members. Since the support fitting deforms according to the deflection of the horizontal member, deformation of the upper frame member can be suppressed. Also, compared to a rod-shaped support member, displacement of the upper frame member with respect to the horizontal member can be suppressed against a force in the width direction of the horizontal member. Examples of the force in the width direction of the horizontal member include wind pressure due to a typhoon, vibration caused by an earthquake, water pressure due to a flood, and the like.

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

[0007] (3) In the support fitting of (2) above, the spring portion has two leaf springs. In a state where the support fitting is disposed between the horizontal member and the upper frame member, the two leaf springs are arranged along the first direction. According to this configuration, the support fitting can improve the support strength of the upper frame member in a state where it is disposed between the upper frame member and the horizontal member and is coupled to both members.

[0008] (4) In the support fitting of (3) above, the two leaf springs curve in opposite directions and project in the first direction such that the interval between the two leaf springs is widest at the middle portion in the vertical direction. According to 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 in a state where the support fitting is disposed between the horizontal cross member and the upper frame member, the leaf spring is configured such that the width direction of the leaf spring follows the second direction. According to this configuration, in a state where the support fitting is disposed between the upper frame member and the horizontal cross member and coupled to both members, the generation of displacement of the upper frame member with respect to the horizontal cross member in the second direction can be suppressed.

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

[0011] (7) In any one of the support fittings of (2) to (6) above, the first fixing portion includes a first plate and a first pole configured to be inserted into a first keyway of the horizontal 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 keyway of the upper frame member and protruding from the second plate. According to this configuration, it is easy to fix the support fitting to the horizontal cross member and the upper frame member.

[0012] (8) The support structure for solving the above problems includes an upper frame member of an opening where a fitting is provided, a horizontal cross member extending above the upper frame member, and any one of the support fittings of (1) to (7) above. According to this configuration, since the support fitting deforms in response to the deflection of the horizontal cross member, the deformation of the upper frame member can be suppressed. Also, the deformation of the opening can be suppressed against the force in the width direction of the horizontal cross member.

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

[0014] (10) The building that solves the above problems is provided with the support structure of the above (9). According to this configuration, deformation of the opening of the building can be suppressed.

Effect of the Invention

[0015] According to the support fitting, support structure, and building of the present disclosure, deformation of the opening can be suppressed against the deflection of the horizontal member and against the horizontal force or lateral sway.

Mode for Carrying Out the Invention

[0017] With reference to FIGS. 1 to 7, the support fitting 1, the support structure 2, and the building 3 will be described. As shown in FIGS. l and 2, the building 3 has fittings 4 such as doors, gates, and windows. The fittings 4 are provided in the opening 5. In this embodiment, as an example of the fitting l, a window provided on the outer wall is mentioned. As an example of the opening 5, an opening in the outer wall to which a window is attached is mentioned.

[0018] The building 3 is provided with a support structure 2 at the opening 5. In the present embodiment, the support structure 2 shows the support structure of the upper frame member 6 of the opening 5 with respect to the horizontal member 7. As an example of the building 3, facilities such as a detached house, an apartment house, a community center, and a kindergarten can be mentioned. In the present 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 fitting 1. The horizontal member 7 is a member constituting the building body. The horizontal member 7 includes a body insertion 7A, a beam, a girder, and a purlin.

[0020] In the present embodiment, the opening 5 is provided under the body insertion 7A as the horizontal member 7. A sweep-out window 4A is provided in the opening 5. The sweep-out window 4A includes a sash and a window body. The sash of the sweep-out window 4A is fixed to the opening 5. The upper frame member 6 of the opening 5 is also called a sill 6A.

[0021] In the present embodiment, the support structure 2 includes a sill 6A located above the sweep-out window 4A, a body insertion 7A extending above the sill 6A, and a support fitting 1. A plurality of support members 1X are arranged between the sill 6A and the body insertion 7A along the longitudinal direction of the body insertion 7A.

[0022] Examples of the support member 1X include a bundle and the support fitting 1. And at least one of the support members 1X is the support fitting 1. In the present embodiment, all of the plurality of support members 1X are the support fitting 1.

[0023] <Support fitting> As shown in FIGS. 2 and 3, the support fitting 1 is arranged between the sill 6A of the opening 5 and the body insertion 7A extending above the sill 6A. The support fitting 1 is connected to the sill 6A and the body insertion 7A. In the present embodiment, the support fitting 1 includes a first fixing portion 8 fixed to the body insertion 7A, a second fixing portion 9 fixed to the sill 6A, and a spring portion 10 connecting the first fixing portion 8 and the second fixing portion 9.

[0024] The spring part 10 is configured to elastically deform in the vertical direction. The spring part 10 is configured to elastically deform in the vertical direction in response to a change in the distance between the awl 6A and the body insert 7A. The spring part 10 is further configured such that the rigidity in the second direction DB is greater than the rigidity in the first direction DA. Note that the first direction DA and the second direction DB of the support fitting 1 are defined as follows in a state where the support fitting 1 is disposed between the awl 6A and the body insert 7A. The first direction DA is a direction along the longitudinal direction of the body insert 7A. The second direction DB is a direction along the width direction of the body insert 7A. In the present embodiment, the spring part 10 has two leaf springs 10A. The two leaf springs 10A are joined 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 by separate members. Examples of the material of the leaf spring 10A include carbon steel, stainless steel, and nickel alloy. The leaf spring 10A of the present embodiment is configured by stainless steel.

[0025] The two leaf springs 10A are arranged along the first direction DA in a state where the support fitting 1 is disposed between the body insert 7A and the awl 6A. Further, the leaf spring 10A is configured such that the width direction of the leaf spring 10A is along the second direction DB. Further, the two leaf springs 10A curve in opposite directions and project in the first direction DA such that the interval between the two leaf springs 10A is widest at the intermediate part 11 in the vertical direction.

[0026] As shown in FIGS. 3 and 4, the first fixing part 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 the first keyway 14 of the body insert 7A. Further, the second fixing part 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 the second keyway 17 of the awl 6A.

[0027] The first pole 13 is fixed to the body plug 7A by the 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. In a state where the first pole 13 is inserted into the first keyway 14, the first pin insertion hole 7B of the body plug 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 brazier 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. In a state where the second pole 16 is inserted into the second keyway 17, the second pin insertion hole 6B of the brazier 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 such that the rigidity of the leaf spring 10A is smaller than the rigidity of the brazier 6A. Specifically, the rigidity of the leaf spring 10A with respect to compression in the vertical direction is smaller than the rigidity with respect to the force that bends the brazier 6A in the vertical direction. Thereby, the bending of the brazier 6A can be suppressed.

[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 (hereinafter, the installation height of the leaf spring 10A) in a state where the support fitting 1 is disposed between the body plug 7A and the brazier 6A 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 of the leaf spring 10A and the dimensions of the leaf spring 10A. The structure of the leaf spring 10A is defined based on the rigidity required for the support fitting 1.

[0032] Referring to FIGS. 5 to 7, the support structure 2 having the support fitting 1 will be described. FIGS. 5 and 6 are front views of a support structure to be compared with the support structure 2 of the present embodiment. FIG. 7 is a front view of the support structure 2 in a state where the support fitting 1 is disposed between the body strut 7A and the rafter 6A. The deflection of the body strut 7A in FIGS. 6 and 7 is emphasized so that the deflection is easily visible.

[0033] As shown in FIGS. 5 and 6, in the support structure to be compared, a support member 1Y is disposed between the body strut 7A and the rafter 6A. The support member 1Y is a bundle 22. The bundle 22 is a short column and has no elasticity. Due to the continuous application of loads such as the weight of the roof over a long period of time, the body strut 7A may deflect. In this case, as the body strut 7A deflects, the rafter 6A connected to the body strut 7A via the bundle 22 also deflects. When the rafter 6A deflects, the opening 5 deforms. As a result, the movement of the fitting 4 (see FIG. 1) is hindered.

[0034] In the longitudinal direction of the body strut 7A, the deflection of the body strut 7A is greater at the central portion 7C of the body strut 7A than at the end portion of the body strut 7A.

[0035] As shown in FIG. 7, in the support structure 2 of the present embodiment, the support fitting 1 is disposed between the body strut 7A and the rafter 6A (see FIG. 2). The support fitting 1 elastically deforms in the vertical direction according to the deflection of the body strut 7A. Specifically, as shown in FIG. 7, the support fitting 1 below the central portion 7C deforms more than the support fitting 1 below the end portion of the body strut 7A.

[0036] The operation of the present embodiment will be described. The spring portion 10 of the support fitting 1 elastically deforms in the vertical direction according to the change in the distance between the rafter 6A and the body strut 7A. Further, 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.

[0037] Therefore, the support fitting 1 can be elastically deformed in the vertical direction. As a result, the support fitting 1 can suppress the deformation of the opening 5 against the force along the width direction of the barrel insertion 7A. Further, the opening 5 of the fitting 4 receives a force not only from the load from above but also from a direction perpendicular to the surface 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 barrel insertion 7A is applied to the support fitting 1. If the support fitting 1 is weak in the width direction of the barrel insertion 7A, the nose 6A may shift with respect to the barrel insertion 7A, and the opening 5 may be deformed. In this regard, as described above, the spring portion 10 of the support fitting 1 is configured such that the rigidity in the second direction DB is greater than the rigidity in the first direction DA. Therefore, the support fitting 1 can suppress the nose 6A from shifting from the barrel insertion 7A even when a force along the width direction of the barrel insertion 7A, that is, a force in the second direction DB, is applied.

[0038] Further, the support fitting 1 has the following function. It is known that the barrel insertion 7A bends downward due to the load over many years. Therefore, for the barrel insertion 7A provided on the outer wall having the opening 5, the height dimension of the barrel insertion 7A is defined so that the amount of deflection due to the deflection of the barrel insertion 7A in the future falls within a predetermined value. Alternatively, for the barrel insertion 7A provided on the outer wall having the opening 5, the length in the longitudinal direction of the barrel insertion 7A is defined. Since the height dimension of the barrel insertion 7A is defined in this way, there is a design limit to the height in the vertical direction of the opening 5 of the outer wall. Further, since the length of the barrel insertion 7A is defined, there is a limit to the length in the width direction of the opening 5 of the outer wall. On the other hand, according to the support structure 2 of the present embodiment, the bending of the barrel insertion 7A is allowed. Therefore, the height dimension of the barrel insertion 7A can be reduced. Alternatively, the length in the longitudinal direction of the barrel insertion 7A can be increased. From this, according to the support structure 2 of the present embodiment, the height in the vertical direction of the opening 5 can be increased. Alternatively, the length in the width direction of the opening 5 can be increased.

[0039] The effects of the present embodiment will be described. (1) The support fitting 1 is configured to elastically deform in the vertical direction. The support fitting 1 is configured such that the rigidity in the second direction DB along the width direction of the barrel insertion 7A is greater than the rigidity in the first direction DA along the longitudinal direction of the barrel insertion 7A. According to this configuration, the support fitting 1 can elastically deform in the vertical direction and is configured such that the rigidity in the second direction DB is large. According to this configuration, the support fitting 1 is disposed between the sill 6A and the barrel insertion 7A and is coupled to both members. In this state, since the support fitting 1 deforms in response to the deflection of the barrel insertion 7A, the deformation of the sill 6A can be suppressed. Also, compared with a rod-shaped support member, the displacement of the sill 6A with respect to the barrel insertion 7A can be suppressed against the force in the width direction of the barrel insertion 7A. Examples of the force in the width direction of the barrel insertion 7A include wind pressure due to a typhoon, vibration caused by an earthquake, water pressure due to a flood, and the like.

[0040] (2) The support fitting 1 includes a first fixing portion 8 fixed to the barrel insertion 7A, a second fixing portion 9 fixed to the sill 6A, and a spring portion 10 connecting the first fixing portion 8 and the second fixing portion 9. The spring portion 10 elastically deforms in the vertical direction in response to a change in the distance between the sill 6A and the barrel insertion 7A. The spring portion 10 is configured such that the rigidity in the second direction DB is greater than the rigidity in the first direction DA. According to this configuration, the support fitting 1 includes the spring portion 10. Therefore, since the support fitting 1 has such a simple structure, it 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. According to this configuration, the support fitting 1 is disposed between the sill 6A and the barrel insertion 7A and is coupled to both members. In this state, the support strength of the sill 6A can be improved. Specifically, compared with the case where the spring portion 10 has one leaf spring 10A, since the sill 6A is more strongly coupled to the barrel insertion 7A, the sill 6A is less likely to vibrate when the fitting 4 is opened and closed. As a result, the deterioration of the sill 6A is suppressed, and thus the smooth opening and closing of the fitting 4 can be maintained over a long period.

[0042] (4) The two leaf springs 10A are curved in opposite directions and protruding in the first direction DA such that the interval between the two leaf springs 10A is widest at the intermediate portion 11 in the vertical direction. According to this configuration, the two leaf springs 10A are curved in opposite directions and protruding in the first direction DA.

[0043] If the two leaf springs 10A are curved in opposite directions and protruding in the first direction DA such that the interval between the two leaf springs 10A is narrowest at the intermediate portion 11 in the vertical direction, there is a possibility that the two leaf springs 10A interfere with each other when the leaf spring 10A is compressed. In this regard, according to the above configuration, interference between the two leaf springs 10A can be avoided.

[0044] (5) The leaf spring 10A is configured such that the width direction of the leaf spring 10A is along the second direction DB in a state where the support fitting 1 is disposed between the barrel plug 7A and the nose 6A. According to this configuration, in a state where the support fitting 1 is disposed between the nose 6A and the barrel plug 7A and coupled to both members, generation of displacement of the nose 6A with respect to the barrel plug 7A in the second direction DB can be suppressed.

[0045] (6) The first fixing portion 8 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 the first keyway 14 of the barrel plug 7A. The second fixing portion 9 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 the second keyway 17 of the nose 6A. According to this configuration, it is easy to fix the support fitting 1 to the barrel plug 7A and the nose 6A.

[0046] (7) The support structure 2 includes a nose 6A of the opening 5 provided with a sweep window 4A, a barrel plug 7A extending above the nose 6A, and a support fitting 1. According to this configuration, since the support fitting 1 deforms in accordance with the deflection of the barrel plug 7A, deformation of the nose 6A can be suppressed. Further, deformation of the opening 5 can be suppressed with respect to the force in the width direction of the barrel plug 7A.

[0047] (8) In the building 3, between the hearth 6A and the body insert 7A, a plurality of support members 1X are arranged along the longitudinal direction of the body insert 7A. At least one of the support members 1X is a support fitting 1. According to this configuration, the deformation of the opening 5 can be suppressed by the support fitting 1.

[0048] In this embodiment, all of the plurality of support members 1X are support fittings 1. In other examples, between the hearth 6A and the body insert 7A, the support fitting 1 is arranged where the amount of deflection of the body insert 7A is large. And, a bundle as the support member 1X is arranged where the amount of deflection of the body insert 7A is small.

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

[0050] <Modification Example> The above embodiment is an exemplification of the forms 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 forms different from the forms exemplified in the above embodiment. An example thereof is a form in which a 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 modification of the embodiment is shown below.

[0051] · As shown in FIG. 8, the spring portion 10 of the support fitting 1 is composed of a plurality of coil springs 10B. In a state where the support fitting 1 is disposed between the barrel insertion portion 7A and the nose 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. Further, the plurality of coil springs 10B may form a plurality of rows. In this modification, four coil springs 10B are arranged so as to connect the first fixing portion 8 and the second fixing portion 9. The four coil springs 10B are arranged in two rows along the second direction DB. The coil spring 10B is configured in the support fitting 1 such that the rigidity in the second direction DB along the width direction of the barrel insertion portion 7A is greater than the rigidity in the first direction DA along the longitudinal direction of the barrel insertion portion 7A. For example, the plurality of coil springs 10B may be arranged on the first plate 12 such that the rigidity in the second direction DB along the width direction of the barrel insertion portion 7A is greater than the rigidity in the first direction DA. Further, each coil spring 10B may be formed of a different material. Further, the dimensions of each coil spring 10B may be changed.

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

[0053] · In the support structure 2 of the present embodiment, the leaf spring 10A of the support fitting 1 disposed on the nose 6A may be formed of a different material depending on the arrangement location of the support fitting 1.

[0054] · In the support structure 2 of the present embodiment, the leaf spring 10A of the support fitting 1 disposed on the nose 6A may be configured to have dimensions different from those of the other support fittings 1 depending on the arrangement location of the support fitting 1.

[0055] · In the support structure 2, an extension member that engages with the support fitting 1 may be further provided. The extension member is disposed between the support fitting 1 and the rake 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. With this bundle, the length of the support fitting 1 can be adjusted.

[0056] · The support fitting 1 may be configured such that its elasticity in the vertical direction changes according to the location where the support fitting 1 is disposed. For example, the support fitting 1 disposed at the central portion 7C of the rake 6A may be configured such that the leaf spring 10A is more easily compressed and deformed than the support fitting 1 disposed at the end of the rake 6A.

[0057] · In the present embodiment, the technology related to the support structure 2 is applied to the rake 6A of the opening 5 of the sweep-out window 4A, but the technology can also be applied to the support structure of the upper frame member 6 in the opening 5 of other fittings. For example, the support structure 2 can be applied to the support structure of the upper frame member 6 in the opening 5 of the entrance door. It can also be applied to the support structure of the upper frame member 6 in the opening 5 of the shutter of the built-in garage.
