Description

[Technical Field]

[0001] The present disclosure relates to retrofit fittings. [Background technology]

[0002] Conventionally, a covering method has been adopted for renovating openings in buildings through renovations, etc., in which new fixtures are installed in the openings. In the renovated fixtures renovated using this covering method, a new frame is attached to the inner periphery of the existing frame attached to the opening of the building (see, for example, Patent Document 1).

[0003] The remodeling fixture described in Patent Document 1 comprises a new frame assembled on all four sides and a long covering material attached to the surface of the new frame. The covering material is fixed to the new frame with screws, thereby restricting its longitudinal position. In the remodeling fixture, an attachment frame may be placed between the new frame and the existing frame, and the new frame may be attached to the existing frame via the attachment frame, with the long covering material attached to the surface of the attachment frame. In this case, the covering material is fixed to the attachment frame with screws, thereby restricting its longitudinal movement. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2018-178575 Summary of the Invention [Problem to be solved by the invention]

[0005] When the cover material is fixed to the attachment frame or the new frame with screws, the fixing work using screws is cumbersome. In response to this, it is possible to adopt a structure in which the cover material is fitted to the attachment frame or the new frame. In this case, there is a structure in which the cover material is formed into a long shape and the cover member is fitted and attached in a state in which it can move in the longitudinal direction.

[0006] However, if the cover material is fitted to the attachment frame or the new frame in a manner that allows it to move in the longitudinal direction, there is a possibility that the cover material may move in the longitudinal direction. Therefore, it is required to be able to restrict the movement of the cover material in the longitudinal direction.

[0007] The present disclosure aims to provide a renovation fitting that can restrict longitudinal movement of a covering material. [Means for solving the problem]

[0008] The present disclosure relates to a renovation fitting that is attached to an existing frame installed in an opening in a building, and that comprises a new frame that is assembled around all four sides, an attachment frame that is attached to the inner periphery of the existing frame while being assembled around the outer periphery of the new frame, a long cover material that is attached to the attachment frame or the new frame, and a restricting structure that restricts longitudinal movement of the cover material.

[0010] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. The remodeling fitting 1 according to this embodiment is a remodeling fitting 1 for renovation, which is formed by newly installing new members while leaving the existing frame 6 fixed to the building 100 attached to the building 100.

[0011] In this specification, "prospect direction" refers to the face direction of the surface material of the shoji screen 10 in the remodeled fitting 1 placed in an opening formed in the wall of the building 100, and "prospect direction" refers to the thickness direction of the surface material (i.e., the depth direction). The "prospect direction" also refers to the indoor / outdoor direction. In the drawings, the outdoor side of the remodeled fitting 1 is the outdoor side X1, and the indoor side of the remodeled fitting 1 is the indoor side X2. The horizontal direction of the remodeled fitting 1 is referred to as the "left-right direction."

[0012] As shown in Figures 1 to 6, the remodeled fitting 1 according to this embodiment is a remodeled sash of a double sliding window type that is fitted into an opening in a building 100. The remodeled fitting 1 is attached to an existing frame 6 that is provided in the opening of the building 100.

[0013] As shown in Figures 1 to 6, the remodeled fitting 1 comprises a new frame 2, an attachment frame 3 attached to the outer periphery of the new frame 2 and attached to the inside of the existing frame 6, interior decorative members 41, 42, 43, exterior decorative covers 51, 52, 53 (covering materials), and shoji screens 10, 10 that are slidably housed within the new frame 2. The existing frame 6 is provided at an opening in a building 100. The new frame 2 is attached to the inside of the existing frame 6 with the attachment frame 3 attached to the outer periphery. The attachment frame 3 is disposed between the existing frame 6 and the new frame 2.

[0014] First, we will explain the configuration of the existing frame 6. As shown in Figures 2 and 3, the existing frame 6 is provided inside the opening of the building 100 and is formed in the shape of a rectangular frame. The existing frame 6 includes an existing upper frame 61, an existing lower frame 62, and existing vertical frames 63 on the left and right.

[0015] 2, the existing upper frame 61 is attached to the upper side of the opening of the building 100, and has guide rails 611, 612 for the existing shoji screen that are erected downward. The inside X2 portion of the existing upper frame 61 is fixed to the building 100 (frame).

[0016] The existing lower frame 62 is attached to the lower side of the opening of the building 100, and has guide rails 621, 622 for the existing shoji screen that stand upright facing upward. The inside X2 portion of the existing lower frame 62 is fixed to the building 100 (frame).

[0017] 3, the existing vertical frames 63 are attached to the left and right vertical sides of the outdoor side X1 of the opening of the building 100. The indoor side X2 portion of the existing vertical frames 63 is fixed to the building 100 (frame).

[0018] As shown in Figure 6, the new frame 2 is attached to the existing frame 6 with the attachment frame 3 attached to the outer periphery. The new frame 2 is made up of four parts and is attached to the inner periphery of the existing frame 6 via the attachment frame 3.

[0019] The new frame 2 comprises a new upper frame 21, a new lower frame 22, and left and right new vertical frames 23. When the new frame 2 is assembled all around, it is fixed with screws at the parts where the new upper frame 21, new lower frame 22, and left and right new vertical frames 23 join together. The attachment frame 3 comprises an upper attachment frame 31 (horizontal attachment frame), a lower attachment frame 32 (horizontal attachment frame), and left and right vertical attachment frames 33.

[0020] The new upper frame 21 is attached to the inner periphery of the existing upper frame 61, with the attachment upper frame 31 sandwiched between them, as shown in Figure 2, when the new frame 2, with the attachment frame 3 attached to the outer periphery, is attached to the existing frame 6. The new upper frame 21 has guide rails 211, 212 on the upper side of the shoji screens 10, 10 that are erected downward.

[0021] When the new frame 2, with the attachment frame 3 attached to its outer periphery, is attached to the existing frame 6, the new sill 22 is attached to the inner periphery of the existing sill 62, with the attachment sill 32 sandwiched between them, as shown in Figure 2. The new sill 22 has guide rails 221, 222 on the lower side of the shoji screens 10, 10 that are erected facing upward.

[0022] The new vertical frame 23 is attached to the inner periphery of the existing vertical frame 63, with the attachment vertical frame 33 sandwiched between them, as shown in Figure 3, when the new frame 2, with the attachment frame 3 attached to the outer periphery, is attached to the existing frame 6.

[0023] The new upper frame 21, the new lower frame 22, and the new vertical frame 23 are formed of, for example, a metal material or a resin material. As shown in Figures 2 and 3, resin angle members 213, 223, and 233 are provided on the indoor side X2 of the new upper frame 21, the new lower frame 22, and the new vertical frame 23, respectively. The resin angle members 213, 223, and 233 are each arranged with a gap between them and the frame member 101.

[0024] The above-mentioned new frame 2 (new upper frame 21, new lower frame 22, and left and right new vertical frames 23) is attached to the inner periphery of the existing frame 6 (existing upper frame 61, existing lower frame 62, and left and right existing vertical frames 63), with the attachment frame 3 (upper attachment frame 31, lower attachment frame 32, and left and right vertical attachment frames 33) arranged around the outer periphery, as shown in Figure 6.

[0025] The attachment frame 3 is attached to the outer periphery of the new frame 2 in a four-way configuration. The attachment frame 3 is attached to the inner periphery of the existing frame 6 in a state where it is attached to the outer periphery of the new frame 2 in a four-way configuration.

[0026] 6, the attachment frame 3 is configured by an upper attachment frame 31, a lower attachment frame 32, and a pair of vertical attachment frames 33 arranged on all four sides to form a rectangle. The upper attachment frame 31, the lower attachment frame 32, and the left and right vertical attachment frames 33 are each made of, for example, aluminum material.

[0027] As shown in Figures 2 and 3, the upper attachment frame 31, the lower attachment frame 32, and the left and right vertical attachment frames 33 are each fixed to the building 100 (skeleton) with screws 36. If gaps are formed between the upper attachment frame 31, the lower attachment frame 32, and the left and right vertical attachment frames 33 and the frame member 101, spacer members 37 are placed between the upper attachment frame 31, the lower attachment frame 32, and the left and right vertical attachment frames 33 and the frame member 101. An example of the spacer member 37 is a thin plate-like member made of a resin material or the like.

[0028] 2 and 3, the renovated fitting 1 has an airtight structure 70. The airtight structure 70 is configured to connect the existing frame 6 side and the new frame 2 side with airtight tape (existing frame side airtight tape 71, connecting airtight tape 72) to the attachment frame 3 attached to the new frame 2. The airtight structure 70 is arranged to connect the existing frame 6 and the attachment frame 3 attached to the new frame 2 in order to improve the airtight performance between the existing frame 6 and the new frame 2.

[0029] 2 and 3, the indoor-side decorative members 41, 42, and 43 are attached to the indoor-side X2 surfaces of the resin angle members 213, 223, and 233 of the new frame 2. The boundary between the indoor-side decorative members 41, 42, and 43 and the inner peripheral surface of the frame member 101 is shielded by a parting material 45 with an L-shaped cross section that is fixed to the building 100 (frame).

[0030] As shown in Figures 4 and 5, the exterior decorative covers 51, 52, and 53 are composed of an upper horizontal decorative cover 51 (horizontal cover material) extending horizontally at the upper side, a lower horizontal decorative cover 52 (horizontal cover material) extending horizontally at the lower side, and a pair of vertical decorative covers 53 (vertical cover material) extending in the vertical direction.

[0031] The upper horizontal decorative cover 51, the lower horizontal decorative cover 52, and the vertical decorative cover 53 are respectively attached to the surface of the outside side X1 of the upper attachment frame 31, the lower attachment frame 32, and the vertical attachment frame 33. As a result, the upper horizontal decorative cover 51, the lower horizontal decorative cover 52, and the vertical decorative cover 53 cover the unevenness of the outside side X1 of the upper attachment frame 31, the lower attachment frame 32, and the vertical attachment frame 33, respectively, and the flat surfaces of the outside side X1 of the outside decorative covers 51, 52, and 53 are exposed to the outside side X1, thereby improving the design.

[0032] 2 and 3, the exterior decorative covers 51, 52, 53 have front-direction extending plates 511, 521, 531 having surfaces facing the exterior side X1, and a pair of engaging protrusions 512, 522, 532 formed on the back sides of the front-direction extending plates 511, 521, 531. The pair of engaging protrusions 512, 522, 532 protrude from the back sides of the front-direction extending plates 511, 521, 531, respectively, and extend in the longitudinal direction of the exterior decorative covers 51, 52, 53, respectively.

[0033] The projection direction extending plates 511, 521, 531 of the upper horizontal decorative cover 51, the lower horizontal decorative cover 52 and the vertical decorative cover 53 are formed as elongated plates extending along the upper attachment frame 31, the lower attachment frame 32 and the vertical attachment frame 33, respectively.

[0034] As shown in FIG. 4 , the vertical decorative cover 53 extends in the up-down direction so that the upper and lower ends of the vertical decorative cover 53 are located outside the left-right ends of the upper horizontal decorative cover 51 and the lower horizontal decorative cover 52. Specifically, the left-right outer end of the upper horizontal decorative cover 51 is located on the left-right inner side of the upper end of the vertical decorative cover 53. The left-right outer end of the lower horizontal decorative cover 52 is located on the left-right inner side of the lower end of the vertical decorative cover 53. In this state, the pair of vertical decorative covers 53 is located outside the upper horizontal decorative cover 51 and the lower horizontal decorative cover 52 in the left-right direction. Therefore, the upper horizontal decorative cover 51 and the lower horizontal decorative cover 52 are attached in a state where their left-right movement is restricted by the pair of vertical decorative covers 53 and they cannot move left-right.

[0035] The upper horizontal decorative cover 51, the lower horizontal decorative cover 52, and the vertical decorative cover 53 each have a pair of engaging protrusions 512, 522, 532 that engage with a pair of engaging protrusions 311, 321, 331 that protrude toward the outside X1 from the outside X1 surfaces of the upper attachment frame 31, the lower attachment frame 32, and the vertical attachment frame 33. The pair of engaging protrusions 311, 321, 331 extend in the longitudinal direction of the upper attachment frame 31, the lower attachment frame 32, and the vertical attachment frame 33, respectively.

[0036] As a result, the upper horizontal decorative cover 51, the lower horizontal decorative cover 52 and the vertical decorative cover 53 are fitted and attached to the upper attachment frame 31, the lower attachment frame 32 and the vertical attachment frame 33, respectively, in a state in which they are able to move in the longitudinal direction when their longitudinal movement is not restricted by the restricting portion 335.

[0037] 7, the vertical attachment frame 33 is formed with a restricting portion 335 (restricting structure) that restricts downward movement of the vertical decorative cover 53. The restricting portion 335 is formed below the pair of engaging protrusions 331 of the vertical attachment frame 33.

[0038] In this embodiment, the restricting portion 335 is configured by a convex portion that protrudes from the vertical attachment frame 33 toward the outside side X1 and extends a predetermined length in the left-right direction. The restricting portion 335 is formed on an extension line of a pair of engaging protrusions 532 of the vertical decorative cover 53 extended downward when the vertical decorative cover 53 is attached to the vertical attachment frame 33. The shape of the restricting portion 335 is not limited to the shape of this embodiment.

[0039] As a result, when the vertical decorative cover 53 is attached to the vertical attachment frame 33, even if the vertical decorative cover 53 attempts to move downward, the lower end portions 532a of the pair of engaging protrusions 532 abut against the regulating portion 335, thereby regulating the downward movement.

[0040] Here, the outer left-right end of the upper horizontal decorative cover 51 is disposed on the inner left-right side of the upper end of the vertical decorative cover 53. The outer left-right end of the lower horizontal decorative cover 52 is disposed on the inner left-right side of the lower end of the vertical decorative cover 53. Therefore, the upper horizontal decorative cover 51 and the lower horizontal decorative cover 52 are restricted from moving in the left-right direction (longitudinal direction) by the vertical decorative cover 53, whose downward movement is restricted by the restricting portion 335.

[0041] According to this embodiment, the following effects are achieved: The renovation fitting 1 of this embodiment includes a new frame 2 that is attached to an existing frame 6 provided at an opening in a building 100 and is configured with a four-way periphery, an attachment frame 3 that is attached to the inner periphery of the existing frame 6 while being attached to the outer periphery of the new frame 2 with a four-way periphery assembled, a long vertical decorative cover 53 that is attached to the attachment frame 3, and a restricting portion 335 that restricts longitudinal movement of the vertical decorative cover 53. As a result, the design can be improved by attaching the vertical decorative cover 53 without using screws or the like, and the vertical decorative cover 53 can be prevented from falling by restricting longitudinal movement of the vertical decorative cover 53.

[0042] Furthermore, in this embodiment, the vertical decorative cover 53 is fitted and attached to the attachment frame 3 in a state in which it is movable in the longitudinal direction when its movement in the longitudinal direction is not restricted by the restricting portion 335. This restricts the movement of the vertical decorative cover 53 in the longitudinal direction, thereby further preventing the vertical decorative cover 53 from falling off.

[0043] In addition, in this embodiment, a restricting portion 335 protruding from the attachment frame 3 is provided to restrict longitudinal movement of the vertical decorative cover 53. The restricting portion 335 can restrict longitudinal movement of the vertical decorative cover 53 with a simple configuration.

[0044] Furthermore, in this embodiment, the longitudinal movement of the vertical decorative cover 53 is restricted by the restricting portion 335, and the longitudinal movement of the upper horizontal decorative cover 51 and the lower horizontal decorative cover 52 is restricted by the vertical decorative cover 53, the movement of which is restricted by the restricting portion 335. As a result, by simply providing the restricting portion 335 that restricts the longitudinal movement of the vertical decorative cover 53, the longitudinal movement of the upper horizontal decorative cover 51 and the lower horizontal decorative cover 52 can also be restricted.

[0045] Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.

[0046] For example, in the above embodiment, the present invention has been described as being applied to a restricting structure (restricting portion 335) that restricts downward movement of a vertical cover material (vertical decorative cover 53), but is not limited thereto. The present invention may also be applied to a restricting structure that restricts lateral movement of horizontal cover materials (upper horizontal decorative cover 51, lower horizontal decorative cover 52).

[0047] In addition, in the above embodiment, the cover material is applied to the case where it is attached to the attachment frame 3, but it is not limited to this. It may also be applied to the case where the cover material is attached to the new frame 2. [Explanation of symbols]
