JP7795883B2 - Renovated fittings - Google Patents

Description

This disclosure relates to renovation fittings.

Conventionally, a covering method has been used to renovate building openings during renovations, etc., by installing new fixtures in the openings. In renovated fixtures renovated using this covering method, a new frame is attached to the inner periphery of the existing frame attached to the building opening (see, for example, Patent Document 1).

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

Japanese Patent Application Laid-Open No. 2018-178575

When fixing the cover material to the attachment frame or new frame with screws, the fixing process is complicated because it requires the use of screws. As an alternative to this, a structure can be considered in which the cover material is fitted into the attachment frame or new frame. In this case, the cover material is formed into a long shape, and the cover member is fitted and attached in a state where it can move longitudinally.

However, if the cover material is designed to fit into the attachment frame or new frame in a manner that allows it to move longitudinally, there is a possibility that the cover material may move longitudinally. Therefore, there is a need to be able to restrict the cover material's movement in the longitudinal direction.

The present disclosure aims to provide a renovation fixture that can restrict longitudinal movement of the cover material.

This disclosure relates to a renovation fitting that is attached to an existing frame installed in an opening in a building, and that includes a new frame assembled on all four sides, an attachment frame that is attached to the inner periphery of the existing frame while being assembled on all four sides 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.

Embodiments of the present disclosure will be described in detail below with reference to the drawings. The remodeling fixture 1 according to this embodiment is a remodeling fixture 1 for renovation, which is formed by installing new components while leaving the existing frame 6 fixed to the building 100 attached to the building 100.

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 referred to as the outdoor side X1, and the indoor side of the remodeled fitting 1 is referred to as the indoor side X2. The horizontal direction of the remodeled fitting 1 is referred to as the "left-right direction."

As shown in Figures 1 to 6, the renovated fixture 1 according to this embodiment is a renovated sliding window-type sash installed in an opening in a building 100. The renovated fixture 1 is attached to an existing frame 6 installed in the opening in the building 100.

As shown in Figures 1 to 6, the renovated fixture 1 comprises a new frame 2, an attachment frame 3 attached to the outer periphery of the new frame 2 and then 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 fitted within the new frame 2. The existing frame 6 is installed in an opening in the 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 positioned between the existing frame 6 and the new frame 2.

First, the structure of the existing frame 6 will be described. As shown in Figures 2 and 3, the existing frame 6 is installed inside the opening of the building 100 and is formed in the shape of a rectangular frame. The existing frame 6 comprises an existing upper frame 61, an existing lower frame 62, and existing left and right vertical frames 63.

As shown in Figure 2, the existing upper frame 61 is attached to the upper side of the opening in the building 100 and has guide rails 611, 612 for the existing shoji screen that stand upright downward. The indoor side X2 portion of the existing upper frame 61 is fixed to the building 100 (framework).

The existing lower frame 62 is attached to the lower side of the opening in the building 100 and has guide rails 621, 622 for the existing shoji screen that stand upright. The indoor side X2 portion of the existing lower frame 62 is fixed to the building 100 (framework).

As shown in Figure 3, the existing vertical frames 63 are attached to the left and right vertical sides of the outdoor side X1 of the opening in the building 100. The indoor side X2 of the existing vertical frames 63 is fixed to the building 100 (frame).

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 constructed from four sides and is attached to the inner periphery of the existing frame 6 via the attachment frame 3.

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 on all four sides, it is fixed with screws at the points 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.

When the new frame 2, with the attachment frame 3 attached to its outer periphery, is attached to the existing frame 6, 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. The new upper frame 21 has guide rails 211, 212 on the upper side of the shoji screens 10, 10 that are erected downward.

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 upward.

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

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

As shown in Figure 6, 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 frames 3 (upper attachment frame 31, lower attachment frame 32, and left and right vertical attachment frames 33) arranged around the outer periphery.

The attachment frame 3 is attached to the outer periphery of the new frame 2, assembling all four sides of it. The attachment frame 3 is then attached to the inner periphery of the existing frame 6, with the attachment frame 3 attached to the outer periphery of the new frame 2, assembling all four sides of it.

As shown in Figure 6, the attachment frame 3 is composed of an upper attachment frame 31, a lower attachment frame 32, and a pair of vertical attachment frames 33 arranged around all four sides to form a rectangle. The upper attachment frame 31, lower attachment frame 32, and left and right vertical attachment frames 33 are each made of, for example, aluminum.

As shown in Figures 2 and 3, the upper attachment frame 31, lower attachment frame 32, and left and right vertical attachment frames 33 are each fixed to the building 100 (frame) with screws 36. If gaps are formed between the upper attachment frame 31, lower attachment frame 32, and left and right vertical attachment frames 33 and the frame member 101, spacer members 37 are placed between the upper attachment frame 31, lower attachment frame 32, and 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.

As shown in Figures 2 and 3, the renovated fitting 1 also 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 positioned 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.

As shown in Figures 2 and 3, the interior decorative members 41, 42, and 43 are attached to the interior X2 surfaces of the resin angle members 213, 223, and 233 of the new frame 2. The boundary between the interior decorative members 41, 42, and 43 and the inner surface of the frame member 101 is shielded by a trim member 45 with an L-shaped cross section that is fixed to the building 100 (frame).

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 vertically.

The upper horizontal decorative cover 51, lower horizontal decorative cover 52, and vertical decorative cover 53 are attached to the surface of the exterior side X1 of the upper attachment frame 31, lower attachment frame 32, and vertical attachment frame 33, respectively. As a result, the upper horizontal decorative cover 51, lower horizontal decorative cover 52, and vertical decorative cover 53 cover the irregularities on the exterior side X1 of the upper attachment frame 31, lower attachment frame 32, and vertical attachment frame 33, respectively, exposing the flat surfaces of the exterior side X1 of the exterior decorative covers 51, 52, and 53 to the exterior side X1, thereby improving the design.

As shown in Figures 2 and 3, the exterior decorative covers 51, 52, and 53 have front-facing extension plates 511, 521, and 531 that have surfaces facing the exterior side X1, and a pair of engagement protrusions 512, 522, and 532 formed on the back side of the front-facing extension plates 511, 521, and 531. The pair of engagement protrusions 512, 522, and 532 protrude from the back side of the front-facing extension plates 511, 521, and 531, respectively, and extend in the longitudinal direction of the exterior decorative covers 51, 52, and 53, respectively.

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

As shown in FIG. 4 , the vertical decorative cover 53 extends in the vertical direction so that its upper and lower ends are positioned 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. Therefore, the upper horizontal decorative cover 51 and the lower horizontal decorative cover 52 are attached in a manner that prevents them from moving left-right by the pair of vertical decorative covers 53.

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

As a result, when longitudinal movement is not restricted by the restricting portion 335, the upper horizontal decorative cover 51, lower horizontal decorative cover 52, and vertical decorative cover 53 are able to move longitudinally and are fitted and attached to the upper attachment frame 31, lower attachment frame 32, and vertical attachment frame 33, respectively.

As shown in Figure 7, the vertical attachment frame 33 is formed with a restricting portion 335 (restricting structure) that restricts the 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.

In this embodiment, the restricting portion 335 is configured as a protrusion that protrudes from the vertical attachment frame 33 toward the exterior side X1 and extends a predetermined length in the left-right direction. When the vertical decorative cover 53 is attached to the vertical attachment frame 33, the restricting portion 335 is formed on an extension line of the pair of engaging protrusions 532 of the vertical decorative cover 53 extended downward. Note that the shape of the restricting portion 335 is not limited to the shape of this embodiment.

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 restricting portions 335, restricting downward movement.

Here, the outer left-right end of the upper horizontal decorative cover 51 is located 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 located on the inner left-right side of the lower end of the vertical decorative cover 53. Therefore, the left-right (longitudinal) movement of the upper horizontal decorative cover 51 and the lower horizontal decorative cover 52 is restricted by the vertical decorative cover 53, whose downward movement is restricted by the restricting portion 335.

This embodiment provides the following advantages. The renovated fixture 1 of this embodiment comprises a new frame 2 that is attached to an existing frame 6 installed in an opening in the building 100 and is configured with a four-way perimeter; 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 perimeter; 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. This improves design by attaching the vertical decorative cover 53 without using screws or the like, and prevents the vertical decorative cover 53 from falling by restricting longitudinal movement of the vertical decorative cover 53.

In addition, in this embodiment, the vertical decorative cover 53 is fitted and attached to the attachment frame 3 in a state where it can move longitudinally when its longitudinal movement is not restricted by the restricting portion 335. This restricts the longitudinal movement of the vertical decorative cover 53, further preventing the vertical decorative cover 53 from falling.

In addition, this embodiment has a restricting portion 335 that protrudes from the attachment frame 3 to restrict longitudinal movement of the vertical decorative cover 53. The restricting portion 335 allows for the restriction of longitudinal movement of the vertical decorative cover 53 with a simple configuration.

In addition, 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, whose movement is restricted by the restricting portion 335. As a result, simply by 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.

The above describes one preferred embodiment of the present disclosure, but the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.

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

In addition, while the above embodiment was applied to a case where the cover material was attached to the attachment frame 3, this is not limited to this. It may also be applied to a case where the cover material is attached to a new frame 2.
