Description

[Technical Field]

[0001] The present invention relates to a renovation fixture that covers at least a portion of an existing frame material with a new frame material. [Background technology]

[0002] When renovating a fixture, the existing frame material of the existing frame is left in the building, and new frame material of a new frame is installed. At least a portion of the existing frame material is covered with the new frame material, and a door body for renovation is installed. Furthermore, as such a renovated fixture, a renovated fixture in which a heat-insulating bridge material is provided on both the existing frame and the new frame has been known (see Patent Document 1).

[0003] In the conventional remodeled fittings described in Patent Document 1, a bridge material is used to connect the exterior and interior portions of the existing frame while keeping them spaced apart, while the exterior and interior frames of the new frame are connected while keeping them spaced apart. This creates an insulated structure between the existing and new frames, ensuring the thermal insulation performance of the remodeled fittings. However, an insulated structure using a bridge material limits the effect of improving the thermal insulation performance of the new frame, making it difficult to significantly improve the thermal insulation performance of the remodeled fittings. Furthermore, depending on the position of the new frame relative to the existing frame, the exterior portion of the existing frame and the interior frame of the new frame may face each other. In this case, heat may be transferred between the exterior portion of the existing frame and the interior frame of the new frame, potentially affecting the thermal insulation performance of the remodeled fittings.

DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of the remodeled fitting of the present invention will be described with reference to the drawings. The renovated fixture of this embodiment is a fixture that has been renovated from an existing fixture installed in a building with a new fixture for renovation, and includes an existing frame material for the existing frame and a new frame material for the new frame. Below, we will explain the frame renovation fixture of this embodiment using the example of a renovated door as the renovated fixture. Therefore, the existing fixture is an existing door, and the new fixture is a newly installed door.

[0010] FIG. 1 is a front view showing a remodeling fitting 1 of this embodiment, showing the schematic configuration of the remodeling fitting 1 installed in a building 10 as seen from outside the room. As shown in the figure, the remodeled fitting 1 is an entrance door installed at the entrance of a building 10, and is positioned between the interior (indoor) and exterior (outdoor) of the building 10. The remodeled fitting 1 is also a single-leaf door, and is installed at an opening 11 of the building 10.

[0011] When the remodeling fitting 1 installed in the building 10 is viewed from the front, the direction that is up and down is the up-down direction R, and the direction that is left and right is the left-right direction S. In Figure 1, the up-down direction R is the vertical direction, and the left-right direction S is the horizontal direction. The indoor / outdoor direction is the indoor / outdoor direction (indoor / outdoor direction) of the remodeling fitting 1 installed in the building 10. Furthermore, the indoor / outdoor direction is the front-to-back direction (depth direction) and the thickness direction of the remodeling fitting 1 when viewed from the front of the remodeling fitting 1 installed in the building 10, and in Figure 1 is the horizontal direction perpendicular to the left-to-right direction S. In this way, the directions related to the remodeling fitting 1 are specified as the directions when it is installed in the building 10. Furthermore, the indoor side and outdoor side of the remodeling fitting 1 are the indoor side and outdoor side when it is installed in the building 10.

[0012] The renovated fixture 1 comprises an existing frame of an existing fixture (not shown in Figure 1) and a new fixture 2 used to renovate the existing fixture. The new fixture 2 comprises a new frame 3 that renovates the existing frame, and a door body 4 (shown by a two-dot chain line) that opens and closes by pivoting. The new frame 3 is a square opening frame (new door frame) that surrounds the door body 4. The door body 4 is a panel body that can be opened and closed, and is connected to the new frame 3 by multiple hinges 4A and 4B so that it can be opened and closed. The hinges 4A and 4B are pivot hinges that connect the upper and lower parts of the door body 4 to the new frame 3.

[0013] The door body 4 is disposed inside the new frame 3 (opening 3A), and opens and closes by moving between the outside of the room and the new frame 3 side (inside of the room) by rotating around two upper and lower hinges 4A, 4B. When opening and closing, the door body 4 moves (rotates) from a closed position inside the new frame 3 toward an open position outside the room to open, and moves from the open position toward the closed position on the new frame 3 side to close. The closed position of the door body 4 is the position where the door body 4 is located when the door body 4 is closed (fully closed position), and the open position of the door body 4 is the position where the door body 4 is located when the door body 4 is opened (fully open position). The door body 4 opens and closes by moving between the closed position and the open position by rotating. The opening 3A of the new frame 3 is opened and closed by the door body 4 opening and closing.

[0014] The new frame 3 has four new frame members 20, 30, 40 (a new upper frame member 20, a new lower frame member 30, and a pair of new vertical frame members 40) that are combined with each other. The opening 3A is formed in a rectangular shape by the new frame members 20, 30, 40 and the new frame 3, and is located inside the new frame 3. The new frame members 20, 30, 40 are frame members (new frame components) that make up the new frame 3, and are arranged along the outer periphery of the door body 4. The new upper frame member 20 and the new lower frame member 30 are new horizontal frame members located at the top and bottom of the new frame 3, and extend in the horizontal direction (left-right direction S). The pair of new vertical frame members 40 are new side frame members located on the left and right sides of the new frame 3, and extend in the vertical direction (up-down direction R). The ends of the new upper frame member 20, the new lower frame member 30, and the left and right new vertical frame members 40 are connected to form a framework for the new frame members 20, 30, 40. The door body 4 is connected to one of the pair of new vertical frame members 40 by hinges 4A and 4B.

[0015] Fig. 2 is a longitudinal cross-sectional view showing the remodeled fitting 1 of this embodiment, showing a part of the remodeled fitting 1 and building 10 cut along a plane including the up-down direction R and the indoor-outdoor direction T. Fig. 3 is a transverse cross-sectional view showing the remodeled fitting 1 of this embodiment, showing a part of the remodeled fitting 1 and building 10 cut along a plane including the left-right direction S and the indoor-outdoor direction T. In Figs. 2 and 3, the structure of the door body 4 is shown in a simplified form.

[0016] As shown in the figure, the existing frame 50 of the existing fitting is attached to the building 10 and is provided in the building 10 and an opening 11 in the building 10. Before the new fitting 2 is installed (before construction), the existing frame 50 is left in the building 10 and the door body of the existing fitting is removed from the existing frame 50. With the existing frame 50 remaining in the building 10, the new frame 3 is placed inside the existing frame 50 (at the opening of the existing frame 50) and is newly installed in the building 10 and the opening 11 in the building 10. The new frame 3 is placed along the existing frame 50 and covers at least a portion (partially or entirely) of the existing frame 50.

[0017] The existing frame 50 is a rectangular opening frame (existing door frame) and has four existing frame members 51-53 (an existing upper frame member 51, an existing lower frame member 52, and a pair of existing vertical frame members 53) that are combined with each other. The existing frame members 51-53 are frame members (existing frame components) that make up the existing frame 50.

[0053] In the remodeled fitting 1 described above, the resin frame portions 22, 42 are provided on the indoor side of the metal frame portions 21, 41 of the newly installed frame materials 20, 40. The resin frame portions 22, 42 have better insulating performance than the metal frame portions 21, 41, which can improve the insulating performance of the newly installed frame materials 20, 40. This improves the insulating performance of the remodeled fitting 1. Furthermore, the resin frame portions 22, 42 are arranged from positions facing the outer peripheries 4C, 4D of the door body 4 to the indoor side of the door body 4. Therefore, the resin frame portions 22, 42 suppress heat transfer between the indoor side of the door body 4 and the metal frame portions 21, 41, improving the insulating performance of the newly installed frame materials 20, 40.

[0054] Making the resin frame portions 22, 42 hollow improves the thermal insulation performance of the resin frame portions 22, 42 and the new frame members 20, 40. Housing insulating material inside the resin frame portions 22, 42 further improves the thermal insulation performance of the resin frame portions 22, 42 and the new frame members 20, 40. Also, improving the thermal insulation performance of the new upper frame member 20 and the pair of new vertical frame members 40 of the renovated fitting 1 improves the thermal insulation performance on the upper side and both the left and right sides of the door body 4. Fixing the metal frame portions 21, 41 and the resin frame portions 22, 42 to the mounting members 25, 45 improves the strength of the connection between the metal frame portions 21, 41 and the resin frame portions 22, 42, and the mounting members 25, 45 also enable the metal frame portions 21, 41 and the resin frame portions 22, 42 to be stably mounted to the skeleton 12 of the building 10.

[0055] The resin frame sections 22, 42 are positioned from a position facing the insulation bridges 51C, 53C of the existing frame members 51, 53 to a position facing the exterior members 51A, 53A. Therefore, the resin frame sections 22, 42 suppress heat transfer between the exterior members 51A, 53A of the existing frame members 51, 53 and the indoor side of the door body 4, improving the insulation performance of the renovated fitting 1. The first and second seal members 43A, 43B seal air in the gap between the resin frame section 42 and the door body 4. Furthermore, an air layer is created in the space 6 surrounded by the resin frame section 42, the door body 4, the first seal member 43A, and the second seal member 43B, improving the insulation performance of the gap between the resin frame section 42 and the door body 4.

[0056] In addition, a space similar to space 6 may be formed by the resin frame portion 22 of the new upper frame material 20. In this case, a first tension material and a second tension material are provided on the new upper frame material 20, and a space is formed surrounded by the resin frame portion 22 of the new upper frame material 20, the door body 4, the first tension material, and the second tension material. In addition, the existing frame materials 51, 53 are not limited to existing frame materials having insulating bridges 51C, 53C, but may be other existing frame materials (for example, existing frame materials without insulating bridges).

[0057] It is sufficient that at least one of the new frame materials 20, 30, 40 has a metal frame portion and a resin frame portion. Therefore, any one of the new frame materials 20, 30, 40 may have a metal frame portion and a resin frame portion, or multiple or all of the new frame materials 20, 30, 40 may have a metal frame portion and a resin frame portion.
