Description

This disclosure relates to refurbished building materials.

Conventionally, a covering method has been adopted for renovating openings in buildings by installing new fixtures in the openings. In the covering method, a renovating fixture is known that includes an existing frame that is installed in the opening of the building, a new frame that is placed on the inner periphery of the existing frame, and an attachment that is placed between the existing frame and the new frame (see, for example, Patent Document 1).

JP 2022-51515 A

In the attachment described in Patent Document 1, the existing frame and attachment are screwed to the exterior facing surface, and the new frame and attachment are screwed to the interior facing surface. For this reason, a remodeling fixture that can be installed from the interior side is desired. Also, when the existing frame is installed so that it is hidden by the frame material, it is difficult to screw the existing frame to the interior facing surface at the site. For this reason, a remodeling fixture that can be easily installed regardless of the existing frame's fit is desired.

The purpose of this disclosure is to provide a remodeling fixture that can be easily installed without relying on the fit of the existing frame.

The present disclosure relates to a remodeling fixture comprising an existing frame provided in an opening of a building and a new frame disposed on the inner periphery of the existing frame, an attachment disposed between the existing frame and the new frame in the opening and fixed to the existing frame and a positioning member that connects the new frame and the attachment and positions the new frame relative to the attachment, the positioning member being L-shaped and having a first plate portion that extends along the projected surface of the attachment and can be hooked and fixed to the projected surface of the attachment, and a second plate portion that is connected to the first plate portion, extends along the projected surface of the new frame, and is fixed to the projected surface of the new frame when the first plate portion is fixed to the projected surface of the attachment.

A first structural example of an embodiment of the present disclosure will be described in detail below with reference to the drawings. As shown in FIG. 1, the renovated fitting 1 of this embodiment is installed in an opening 11 of a building 100, such as an apartment building. FIG. 1 shows the renovated fitting 1 as viewed from the inside of the room. The renovated fitting 1 is formed by renovating an existing frame 2 that has already been installed by attaching a new frame 3 to it.

In this specification, "prospect direction" refers to the surface direction of the surface material of the shoji screen 12 of the renovated fitting 1 placed in the opening 11 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). "Prospect direction" is also the indoor/outdoor direction. "Prospect surface" refers to each surface of the renovated fitting 1 facing the outside and inside of the room, and "prospect surface" refers to the surface of the renovated fitting 1 that extends in the indoor/outdoor direction. In the drawings, the outdoor side of the prospective direction of the renovated fitting 1 is the outdoor side X1, and the indoor side of the prospective direction of the renovated fitting 1 is the indoor side X2. The horizontal direction in the prospective direction of the renovated fitting 1 is the left/right direction.

As shown in Figure 1, the renovated fitting 1 is constructed by attaching a new frame 3 via an attachment 4 (see Figure 2) to the inner periphery of an existing frame 2 installed in an opening 11 of a building 100.

In this embodiment, a separate L-shaped connecting member 237 is connected to the indoor side X2 end of the existing vertical frame 23, but this is not limited to this. A rib protruding from the existing vertical frame 23 may be provided integrally with the existing vertical frame 23 without providing the L-shaped connecting member 237.

The attachment vertical frame 43 connects the existing vertical frame 23 and the new vertical frame 33. As shown in FIG. 2, the attachment vertical frame 43 is a long member that is arranged between the existing vertical frame 23 and the new vertical frame 33 at both left and right ends of the opening 11 and extends in the up and down direction. The attachment vertical frame 43 is connected to the inner periphery side of the existing vertical frame 23. The attachment vertical frame 43 is arranged inside the existing vertical frame 23 in the left and right direction and is fixed to the existing vertical frame 23.

The attachment vertical frame 43 extends in the indoor/outdoor direction. The attachment vertical frame 43 has an indoor/outdoor direction extension plate 431 that extends in the indoor/outdoor direction, an indoor side end extension portion 432 (indoor side extension portion) that extends from the indoor side X2 end of the indoor/outdoor direction extension plate 431 to the indoor side X2, and an L-shaped protruding piece 433 that protrudes outward in the left/right direction at the outdoor side X1 end side midway in the indoor/outdoor direction of the indoor/outdoor direction extension plate 431.

The indoor/outdoor extension plate 431 is fixed to the indoor/outdoor extension plate 231 of the existing vertical frame 23 by screws 131 midway in the indoor/outdoor direction. The L-shaped protruding piece 433 protrudes outward in the left/right direction along the indoor side X2 surface of the outdoor extension plate 232 of the existing vertical frame 23.

The indoor/outdoor extending plate 431 has a step portion 434 arranged on the end side of the outdoor side X1. The step portion 434 has an outer plate portion 435, an inner plate portion 437, and a step 436. The outer plate portion 435 is formed in a plate shape extending in the indoor/outdoor direction at the end of the outdoor side X1. The inner plate portion 437 is connected to the indoor side X2 of the outer plate portion 435 via a step 436, and is formed in a plate shape extending in the indoor/outdoor direction inside the outer plate portion 435 in the left-right direction.

A vertical frame cover part 53 is fixed to the end of the indoor/outdoor extension plate 431 on the outdoor side X1. The vertical frame cover part 53 has an L-shaped L-shaped fixing piece 531 and an L-shaped cover part 532 connected to the end of the L-shaped fixing piece 531 on the outdoor side X1.

The L-shaped fixed piece 531 is formed in an L-shape that opens toward the indoor side X2 and toward the outside in the left-right direction. The L-shaped fixed piece 531 has a fixed piece 531a that extends in the indoor/outdoor direction, and an extension piece 531b that extends outward in the left-right direction from the end of the fixed piece 531a on the outdoor side X1.

The fixing piece 531a is arranged along the inner surface in the left-right direction of the outer plate portion 435 of the step portion 434 arranged on the end side of the outside X1 of the indoor/outdoor direction extension plate 431 of the attachment vertical frame 43. When attaching the vertical frame cover portion 53 to the attachment vertical frame 43, the fixing piece 531a of the L-shaped fixing piece 531 of the vertical frame cover portion 53 can be moved from the outside X1 to the inside X2 along the inner surface in the left-right direction of the outer plate portion 435 of the step portion 434 of the indoor/outdoor direction extension plate 431 of the attachment vertical frame 43, and the vertical frame cover portion 53 can be engaged and attached to the attachment vertical frame 43. The fixing piece 531a is fixed to the indoor/outdoor direction extension plate 431 of the attachment vertical frame 43 by the screw 132.

The extension piece 531b bends outward in the left-right direction from the outside X1 end of the fixed piece 531a at the outside X1 end of the indoor/outdoor extension plate 431 of the attachment vertical frame 43, and extends outward in the left-right direction. An airtight material 533 is attached to the inside X2 surface of the fixed piece 531a. The airtight material 533 is disposed between the inside X2 surface of the extension piece 531b and the outside X1 surface of the outdoor extension plate 232 of the existing vertical frame 23.

The L-shaped cover portion 532 is positioned to protrude further toward the outside X1 than the existing vertical frame 23, and is formed in an L shape that opens toward the inside X2 and toward the inside in the left-right direction. The L-shaped cover portion 532 is positioned on the outside X1 of the new vertical frame 33 and on the outside in the left-right direction. The L-shaped cover portion 532 is positioned so as to cover at least a portion of the end of the outside X1 of the new vertical frame 33.

The positioning member 7, which will be described later, is connected to the indoor end extension 432. The positioning member 7 connects the inner left-right facing surface of the indoor end X2 of the attachment vertical frame 43 to the indoor side X2 facing surface of the new vertical frame indoor side hollow portion 332, and positions the new vertical frame 33 relative to the attachment vertical frame 43.

As shown in FIG. 3, the indoor end extension 432 is formed with a pair of slide fixing holes 432a (hook holes) spaced apart in the vertical direction. The pair of slide fixing holes 432a are formed penetrating the indoor end extension 432 in the thickness direction. As shown in FIG. 3, the slide fixing hole 432a has a large diameter hole 432b and a pair of slide grooves 432c. The large diameter hole 432b is formed in a circular shape. The slide grooves 432c extend from the large diameter hole 432b to both sides in the vertical direction and are formed with a width narrower than the diameter of the large diameter hole 432b.

As shown in FIG. 2, the new vertical frame 33 is attached to the inner periphery of the vertical attachment frame 43 (the inner side in the left-right direction of the vertical attachment frame 43) via a spacer member 631. The new vertical frame 33 is placed on the inner side in the left-right direction of the spacer member 631, with the plate-shaped spacer member 631 sandwiched between the inner side in the left-right direction of the indoor-outdoor extension plate 431 of the vertical attachment frame 43.

The new vertical frame 33 has a hollow section 331 on the outside of the new vertical frame, a hollow section 332 on the inside of the new vertical frame, and an open section 333 on the outside.

The newly installed vertical frame exterior hollow section 331 and the newly installed vertical frame interior hollow section 332 are both formed in a long, narrow rectangular hollow shape extending in the indoor/outdoor direction, and are arranged side by side in the indoor/outdoor direction. The newly installed vertical frame exterior hollow section 331 is arranged on the outdoor side X1, and the newly installed vertical frame interior hollow section 332 is arranged on the indoor side X2.

The new vertical frame outer hollow section 331 is fixed to the attachment vertical frame 43 by the screw 133. The screw 133 is inserted through the through hole 331b of the inner plate section 331a on the inner side in the left-right direction of the new vertical frame outer hollow section 331, and penetrates the outer plate section 331c on the outer side in the left-right direction of the new vertical frame outer hollow section 331, the spacer member 631, and the indoor/outdoor extending plate 431 of the attachment vertical frame 43, in order from the inner side to the outer side in the left-right direction. As a result, the screw 132 fixes the outer plate section 331c on the outer side in the left-right direction of the new vertical frame outer hollow section 331, the spacer member 631, and the indoor/outdoor extending plate 431 of the attachment vertical frame 43 by tightening them together, thereby fixing the new vertical frame outer hollow section 331 to the attachment vertical frame 43.

The outdoor opening section 333 is formed at the end of the outdoor side X1 of the new vertical frame 33, opening toward the outdoor side X1. An airtight material arrangement member 334 is attached to the outdoor opening section 333. An airtight material 335 is attached to the outdoor side X1 of the airtight material arrangement member 334. The airtight material 335 is arranged between the outdoor side X1 surface of the end of the outdoor side X1 of the new vertical frame 33 and the indoor side X2 surface of the left-right extending cover part 532a that extends inward in the left-right direction (inward in the view direction) of the L-shaped cover part 532 of the vertical frame cover part 53. As a result, the airtight material 335 is arranged between the vertical frame cover part 53 of the attachment vertical frame 43 and the new vertical frame 33 on the outdoor side X1.

A positioning member 7 is fixed to the indoor side X2 surface of the new vertical frame indoor side hollow section 332. The positioning member 7 is provided on the indoor side X2 end side of the new vertical frame 33 and the attachment vertical frame 43. The positioning member 7 connects the inner visible surface in the left-right direction of the indoor side X2 end of the attachment vertical frame 43 and the indoor side X2 visible surface of the new vertical frame indoor side hollow section 332. The positioning member 7 determines the position of the new vertical frame 33 relative to the attachment vertical frame 43. Details of the positioning member 7 will be described later.

A resin angle member 632 is attached to the inside of the interior side X2 of the new vertical frame 33 in the left-right direction. A vertical frame interior side decorative cover 633 is attached to the resin angle member 632. The vertical frame interior side decorative cover 633 is formed in an L shape with the exterior side X1 and the outside in the left-right direction open, and is positioned so as to cover the end side of the interior side X2 of the attachment vertical frame 43 and the end side of the interior side X2 of the new vertical frame 33.

The positioning member 7 will be described in detail. The positioning member 7 is formed in an L-shape that opens toward the indoor side X2 and toward the inside in the left-right direction. The positioning member 7 has an indoor-outdoor extending positioning plate 71 (first plate portion) that extends in the indoor-outdoor direction, and a new frame fixing plate 72 (second plate portion) that extends in the left-right direction.

The indoor/outdoor extending positioning plate 71 extends along the inner projected surface in the left-right direction of the vertical attachment frame 43. The indoor/outdoor extending positioning plate 71 can be hooked onto and fixed to the inner projected surface in the left-right direction of the vertical attachment frame 43.

As shown in FIG. 3, two pin members 73 are attached to the indoor/outdoor extending positioning plate 71 so that their heads 732 are positioned on the indoor end extension portion 432 side of the vertical attachment frame 43. The two pin members 73 are arranged apart in the vertical direction, and each has a shaft portion 731 that is attached to the new frame fixing plate 72 and extends in the left-right direction, and a head portion 732 that is connected to the outer end of the shaft portion 731 in the left-right direction.

When attaching the indoor/outdoor extending positioning plate 71 of the positioning member 7 to the indoor end extension portion 432 of the attachment vertical frame 43, as shown in FIG. 3, the head 732 of the pin member 73 attached to the indoor/outdoor extending positioning plate 71 is inserted into the large diameter hole 432b of the slide fixing hole portion 432a formed in the indoor end extension portion 432 of the attachment vertical frame 43, and as shown in FIG. 4, the shaft portion 731 of the pin member 73 is moved from the large diameter hole 432b to the slide groove 432c whose width is narrower than the diameter of the large diameter hole 432b, thereby attaching the indoor/outdoor extending positioning plate 71 of the positioning member 7 to the indoor end extension portion 432 of the attachment vertical frame 43. As a result, the indoor/outdoor extending positioning plate 71 is fixed by the pin member 73 to the inner prospective surface in the left/right direction of the indoor end extension portion 432 of the attachment vertical frame 43.

As shown in FIG. 2, the new frame fixing plate 72 is connected to the end of the outdoor side X1 of the indoor/outdoor extending positioning plate 71. The new frame fixing plate 72 extends along the indoor side X2 visible surface of the new vertical frame 33. The new frame fixing plate 72 is screwed to the indoor side X2 visible surface of the new vertical frame 33 with the indoor/outdoor extending positioning plate 71 hooked and fixed to the inner visible surface in the left/right direction of the attachment vertical frame 43.

The new frame fixing plate 72 is fixed to the visible surface of the indoor side X2 of the new vertical frame indoor side hollow section 332 by the screw 134. The screw 134 has a head 134a and a shaft 134b that extends linearly from the head 134a to the outdoor side X1. The head 134a of the screw 134 is disposed on the indoor side X2 surface of the indoor/outdoor direction extending positioning plate 71, and the shaft 134b penetrates the new frame fixing plate 72 and the indoor side X2 end panel 332a of the new vertical frame indoor side hollow section 332 in order from the indoor side X2 to the outdoor side X1.

When the positioning member 7 is fixed to the new vertical frame 33 by the screw 134, as shown in FIG. 5, the positioning plate 71 extending in the indoor/outdoor direction of the positioning member 7 is hooked and attached to the indoor end extension portion 432 of the attachment vertical frame 43, and then the new frame fixing plate 72 and the end plate 332a of the indoor side X2 of the new vertical frame indoor side hollow portion 332 are fastened together by the screw 134 on the visible surface of the indoor side X2 of the new vertical frame 33 from the indoor side X2, thereby fixing the positioning plate 71 extending in the indoor/outdoor direction of the positioning member 7 to the new vertical frame 33. In this way, the positioning member 7 can be easily fixed to the new vertical frame 33 by the screw 134 on the visible surface of the indoor side X2 of the new vertical frame 33 from the indoor side X2.

According to this embodiment, the following effects are achieved. In the remodeling fixture 1 of this embodiment, the positioning member 7 is formed in an L-shape and has an indoor/outdoor extending positioning plate 71 that extends along the projected surface of the attachment vertical frame 43 and can be hooked and fixed to the projected surface of the attachment vertical frame 43, and a new frame fixing plate 72 that extends along the projected surface of the new vertical frame 33 and is fixed to the projected surface of the new vertical frame 33 when the indoor/outdoor extending positioning plate 71 is fixed to the projected surface of the attachment vertical frame 43. Therefore, since the indoor/outdoor extending positioning plate 71 of the positioning member 7 can be hooked and fixed to the projected surface of the attachment vertical frame 43, the attachment vertical frame 43 can be easily fixed to the existing vertical frame 23 even in the case of a fit in which the existing vertical frame 23 is housed and attached so as to be hidden by the frame member. This makes it easy to install regardless of the fit of the existing vertical frame 23.

In addition, in this embodiment, the positioning member 7 is provided on the end side of the interior side X2 of the new vertical frame 33 and the attachment vertical frame 43. This allows screw fixing work to be performed on the visible surface of the interior side X2 of the new vertical frame 33 from the interior side X2. Therefore, since the work of attaching the positioning member 7 can be performed from the interior side X2, construction can be easily performed.

In addition, in this embodiment, the indoor/outdoor extending positioning plate 71 has a pin member 73 penetrating therethrough, and the vertical attachment frame 43 has a slide fixing hole 432a that can be hooked by sliding the head 732 of the pin member 73 with the head 732 inserted. This allows the indoor/outdoor extending positioning plate 71 to be easily fixed to the vertical attachment frame 43 simply by hooking the head 732 of the pin member 73 of the indoor/outdoor extending positioning plate 71 into the slide fixing hole 432a of the vertical attachment frame 43. This makes it easy to fix the indoor/outdoor extending positioning plate 71 to the projected surface of the vertical attachment frame 43.

In addition, in this embodiment, an airtight material 335 is placed between the L-shaped cover portion 532 and the new vertical frame 33. This ensures airtightness between the vertical frame cover portion 53 and the new vertical frame 33 on the outside side X1.

Next, a second structural example of one embodiment will be described. Compared to the first structural example, the second structural example differs in the direction in which the vertical frame cover part 53A and the attachment vertical frame 43A engage when attaching the vertical frame cover part 53A to the attachment vertical frame 43A. In the description of the second structural example, the description of the same configuration as the first structural example will be omitted.

In the second structural example, as shown in FIG. 6, the attachment vertical frame 43A has an indoor/outdoor extending plate 431A instead of the indoor/outdoor extending plate 431 of the first structural example of the first embodiment. The indoor/outdoor extending plate 431A has a step portion 434A arranged on the end side of the outdoor side X1, and an inner protruding protrusion 438 protruding inward in the left-right direction from the end of the outdoor side X1 of the outer plate portion 435a of the step portion 434A. The outer plate portion 435a of the step portion 434A is formed so that the length of the outdoor side X1 is shorter than the outer plate portion 435 of the step portion 434 of the first embodiment. Between the step 436 of the step portion 434A and the inner protruding protrusion 438, an inner opening recess 439 that opens toward the inside in the left-right direction is formed.

The L-shaped fixing piece 531A of the vertical frame cover part 53A has a fixing piece 531c instead of the fixing piece 531a extending in the indoor/outdoor direction of the L-shaped fixing piece 531 of the first structural example. The fixing piece 531c has a step portion 538 that is engaged in a stepped shape, and an outer protruding protrusion 539. The step portion 538 has an outer plate portion 538a, an inner plate portion 538c, and a step 538b.

The outer plate portion 538a is formed in a plate shape extending in the indoor/outdoor direction at the end of the indoor side X2. The outer plate portion 538a is disposed in the inner open recess 439 of the indoor/outdoor direction extending plate 431A of the attachment vertical frame 43A.

The inner plate portion 538c is connected to the outdoor side X1 of the outer plate portion 538a via a step 538b, and is formed in a plate shape extending in the indoor/outdoor direction, inside the outer plate portion 538a in the left-right direction.

The outer protrusion 539 protrudes outward in the left-right direction from the outer left-right surface of the inner plate portion 538c at the outdoor side X1 of the step 538b. An outer opening recess 540 that opens outward in the left-right direction is formed between the step 538b and the outer protrusion 539. The inner protrusion 438 formed at the end of the outdoor side X1 of the indoor/outdoor extending plate 431A of the attachment vertical frame 43A is arranged in the outer opening recess 540.

When attaching the vertical frame cover part 53A to the vertical attachment frame 43A, the vertical frame cover part 53A is moved from the inside to the outside in the left-right direction toward the vertical attachment frame 43A, so that the outer plate part 538a of the step part 538 of the vertical frame cover part 53A engages with the inner open recess 439 of the vertical attachment frame 43A, and the inner protrusion 438 of the indoor/outdoor extending plate 431A of the vertical attachment frame 43A engages with the upward open recess 531e of the vertical frame cover part 53A, thereby engaging and attaching the vertical frame cover part 53A to the vertical attachment frame 43A.

As described above, in the first structural example and the second structural example, in the first structural example shown in FIG. 2, the vertical frame cover part 53A is moved in the indoor/outdoor direction to engage and attach to the vertical attachment frame 43A, whereas in the second structural example shown in FIG. 6, the vertical frame cover part 53A is moved in the left-right direction (facing direction) to engage and attach to the vertical attachment frame 43A. Therefore, the direction in which the vertical frame cover parts 53, 53A are engaged and attached to the vertical attachment frames 43, 43A differs between the first structural example and the second structural example.
