Description

[Technical field]

[0001] The present invention relates to a renovation fixture in which a new frame material is fixed to a reinforcing material by fixing screws. [Background technology]

[0002] When renovating a fixture, the existing frame material of the existing fixture is left in place and a new frame material for the renovation is installed. At that time, the new frame material may be fixed to a reinforcing material to reinforce it. In addition, as such a renovated fixture, a renovated door that has a reinforcing material fixed to the vertical frame of the existing door frame, which is the existing frame material, and an outer frame fixed to the exterior part of the vertical frame of the new door frame, which is the new frame material, is known (see Patent Document 1).

[0003] In the conventional remodeled door described in Patent Document 1, the reinforcing material has an extension extending beyond the vertical frame of the existing door frame toward the exterior side, and the vertical frame of the new door frame is fixed to the extension of the reinforcing material by a connecting screw. In addition, the outer frame is arranged from the exterior part of the vertical frame of the new door frame to the exterior wall of the building, and covers the vertical frame and the connecting screw of the existing door frame from the exterior side. However, in a remodeled door with an outer frame, in addition to the outer frame, screws for fixing the outer frame and screw covers for hiding the screws are required, and the number of parts tends to be large. In addition, adjustment work by processing the outer frame is required to correspond to various fittings of the outer frame to the peripheral part of the remodeled door (for example, the exterior wall of the building), and there is a risk that the construction of the remodeled door will be troublesome.

[0004] Therefore, in order to reduce costs, it is required to install a remodeled door without an outer frame. However, if the outer frame is eliminated, the tip of the connecting screw protruding from the reinforcement material may be exposed, and a separate means is required to ensure the design and safety of the part where the vertical frame of the new door frame is fixed to the reinforcement material. As a result, there is a concern that the work of installing the remodeled door will increase. In addition, the reinforcement material is also required to be able to accommodate various fittings to the periphery of the remodeled door. [Prior art documents] [Patent documents]

The renovated fixture of this embodiment is a fixture that has been renovated from an existing fixture with a new fixture for renovation, and is equipped with an existing frame material of the existing frame and a new frame material of the new frame. Below, the frame renovated fixture of this embodiment will be explained using the example of the renovated fixture being a renovated door. Therefore, the existing fixture is an existing door, and the new fixture is a newly installed door.

[0011] FIG. 1 is a front view showing a remodeling fixture 1 of this embodiment, and shows the remodeling fixture 1 installed in a building 10 as viewed from the outside of the room. As shown in the figure, the remodeling fixture 1 is an entrance door installed at the entrance of a building 10, and is disposed between the interior (indoors) and exterior (outdoors) of the building 10. The remodeling fixture 1 is also a single-leaf door, and is installed at an opening 11 of the building 10.

[0012] 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 FIG. 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. Also, the indoor / outdoor direction is the front-to-back direction (depth direction) when the remodeling fitting 1 installed in the building 10 is viewed from the front, and in FIG. 1, it 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 by the directions when it is installed in the building 10. Also, the indoor side and the outdoor side of the remodeling fitting 1 are the indoor side and the outdoor side when it is installed in the building 10.

[0013] The renovated fitting 1 comprises an existing frame of an existing fitting (not shown in FIG. 1) and a new fitting 2 used to renovate the existing fitting. The new fitting 2 comprises a new frame 3 for renovating the existing frame, and a door body 20. The door body 20 is an openable and closable panel body, and is connected to the new frame 3 by a number of hinges 21, 22, and 23 so that it can be opened and closed. The door body 20 is disposed inside the new frame 3, and rotates between the outside of the room and the new frame 3 side to open and close. When opening and closing, the door body 20 rotates from a closed position inside the new frame 3 to an open position on the outside of the room to open, and rotates from the open position to a closed position on the new frame 3 side to close.

[0014] The new frame 3 is a square-shaped opening frame (new door frame) and has four new frame members 4-7 (a new upper frame member 4, a new lower frame member 5, and a pair of new vertical frame members 6, 7) that are combined with each other. The new frame members 4-7 are new frame components that make up the new frame 3, and each is made of a metal (for example, aluminum alloy) shaped member formed by extrusion molding. The new upper frame member 4 and the new lower frame member 5 are upper and lower new horizontal frame members located at the upper and lower parts of the new frame 3, and extend in the horizontal direction (left-right direction S). The pair of new vertical frame members 6, 7 are 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 4, the new lower frame member 5, and the left and right new vertical frame members 6, 7 are connected to each other to form a frame of the new frame members 4-7.

[0015] The door body 20 has a door end portion 24 located on the door end side and a hanging portion 25 located on the hanging side. The door end portion 24 is a part on the door end side including the end of the door body 20 on the door end side, and the hanging portion 25 is a part on the hanging side including the end of the door body 20 on the hanging side. When the door body 20 is closed, one of the newly installed vertical frame members 6, 7 of the newly installed frame 3 is located on the door end portion 24 side of the door body 20, and the other newly installed vertical frame member 7 is located on the hanging portion 25 side of the door body 20. The door end portion 24 of the door body 20 is arranged along the newly installed vertical frame member 6 on the door end portion 24 side, and the hanging portion 25 of the door body 20 is arranged along the newly installed vertical frame member 7 on the hanging portion 25 side. The hinges 21, 22, and 23 are spaced apart from each other in the vertical direction R and are attached to the hanging portion 25 of the door body 20 and the newly installed vertical frame material 7 on the hanging portion 25 side, connecting the hanging portion 25 of the door body 20 to the newly installed vertical frame material 7 on the hanging portion 25 side.

[0016] Fig. 2 is a vertical 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 horizontal 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 door body 20 is indicated by a two-dot chain line. As shown in the figure, the existing frame 30 of the existing fitting is attached to the building 10 and provided in the opening 11 of the building 10. Before the new fitting 2 is installed (before construction), the door body of the existing fitting is removed from the existing frame 30, leaving the existing frame 30. With the existing frame 30 remaining in the opening 11 of the building 10, the new fitting 2 is placed inside the existing frame 30 and newly installed in the opening 11 of the building 10. The new frame 3 is placed inside the existing frame 30 and connected to the existing frame 30, covering at least a portion of the existing frame 30.

[0017] The existing frame 30 is a rectangular opening frame (existing door frame) and has four existing frame members 31-34 (an existing upper frame member 31, an existing lower frame member 32, and a pair of existing vertical frame members 33, 34) that are combined with each other. The existing frame members 31-34 are existing frame components that make up the existing frame 30, and each is made of a metal (e.g., aluminum alloy) shaped member formed by extrusion molding. The existing upper frame member 31 and the existing lower frame member 32 are upper and lower existing horizontal frame members located at the top and bottom of the existing frame 30, and extend in the horizontal direction (left-right direction S). The pair of existing vertical frame members 33, 34 are located on the left and right sides of the existing frame 30 and extend in the vertical direction (up-down direction R). The ends of the existing upper frame material 31, the existing lower frame material 32, and the existing left and right vertical frame materials 33, 34 are connected to each other, so that the existing frame materials 31 to 34 form a framework.

[0018] The existing frame members 31-34 are attached to the building 10 and provided at the opening 11 of the building 10. The new frame members 4-7 are provided on the inside of the existing frame 30 with respect to the existing frame members 31-34, respectively, and are arranged along the existing frame members 31-34, covering at least a part (partially or entirely) of the existing frame members 31-34. In this way, the remodeling fixture 1 includes the existing frame members 31-34 provided at the opening 11 of the building 10, and the new frame members 4-7 covering the existing frame members 31-34. In addition, at least one of the new frame members 4-7 is reinforced by the reinforcing member 40. The new frame members 4-7 are supported by the reinforcing member 40, and the movement and deformation of the new frame members 4-7 are restricted.

[0019] The reinforcing material 40 is provided on a portion of the new frame members 4-7 and the existing frame members 31-34 in the longitudinal direction, on a plurality of locations of the new frame members 4-7 and the existing frame members 31-34 in the longitudinal direction, or on the entirety of the new frame members 4-7 and the existing frame members 31-34 in the longitudinal direction. Here, the new frame member reinforced by the reinforcing material 40 is the new vertical frame member 7 located on the hanging portion 25 side of the door body 20, and the existing frame member covered by the new frame member reinforced by the reinforcing material 40 is the existing vertical frame member 34 covered by the new vertical frame member 7. The reinforcing material 40 is provided on a portion of the new vertical frame member 7 and the existing vertical frame member 34 in the longitudinal direction (up-down direction R).

[0020] The multiple hinges 21-23 are provided at intervals in the longitudinal direction of the new vertical frame member 7 (see FIG. 1). When the door body 20 rotates (opens and closes), the new vertical frame member 7 receives a load from the door body 20 through the hinges 21-23, which may cause movement and deformation of the new vertical frame member 7. In particular, the new vertical frame member 7 is likely to move and deform at the location where the uppermost hinge 21 of the multiple hinges 21-23 is attached to the new vertical frame member 7. Therefore, a reinforcing member 40 is provided at the same position as the hinge 21 in the longitudinal direction of the new vertical frame member 7, and the location where the hinge 21 is attached on the new vertical frame member 7 is reinforced by the reinforcing member 40. This restricts movement and deformation of the location where the hinge 21 is attached on the new vertical frame member 7.

[0021] FIG. 4 is a cross-sectional view showing a portion of the renovated fitting 1 of this embodiment including the existing vertical frame member 34 and the new vertical frame member 7, and is an enlarged view of a portion of FIG. 3 showing the frame renovated structure of the renovated fitting 1.

The tip side portion 52A of the fixing screw 52 and the tip side portion 53A of the mounting screw 53 are located between the cover 60 (here, the first covering piece 65) and the existing vertical frame member 34 in the indoor-outdoor direction T, and are located between the second covering piece 66 and the mounting portion 61 in the left-right direction S. The second covering piece 66 and the mounting portion 61 protrude from the first covering piece 65 toward the existing vertical frame member 34 toward the indoor side, and are arranged in parallel while being spaced apart in the left-right direction S.

[0041] The cover 60 is detachable from the reinforcing material 40. When the cover 60 is not attached to the reinforcing material 40, the tip side 52A of the fixing screw 52 and the tip side 53A of the mounting screw 53 are exposed on the outdoor side of the existing vertical frame material 34. In contrast, by attaching the cover 60 to the reinforcing material 40, the tip side 52A of the fixing screw 52 and the tip side 53A of the mounting screw 53 are entirely covered and shielded by the covering portion 62 of the cover 60 on the outdoor side of the existing vertical frame material 34. The cover 60 hides the tip side 52A of the fixing screw 52 and the tip side 53A of the mounting screw 53 by the covering portion 62, preventing the exposure of the tip side 52A of the fixing screw 52 and the tip side 53A of the mounting screw 53.

[0042] The open portion 63 of the cover 60 is located between the tip of the mounting portion 61 located on the indoor side and the tip of the covering portion 62 (second covering piece 66). The open portion 63 is arranged toward the existing vertical frame member 34 side (here, the indoor side where the existing vertical frame member 34 is located), and opens the inside of the cover 60 toward the indoor side. A backup material 58 is provided on the inside of the cover 60, and a sealant 59 is provided in the area between the cover 60 and the existing vertical frame member 34. The sealant 59 is made of an indefinite sealing material, is received by the backup material 58 and the reinforcing material 40, and is filled in the area between the cover 60 and the existing vertical frame member 34. The area between the cover 60 and the existing vertical frame member 34 is blocked by the sealant 59.

[0043] Depending on how the reinforcing material 40 fits around the periphery of the renovated fitting 1, the cover 60 may come into contact with the periphery of the renovated fitting 1 (for example, the framework 12 and exterior wall 13 of the building 10), causing the cover 60 to interfere with the periphery of the renovated fitting 1. In this case, the cover 60 is removed from the reinforcing material 40, the reinforcing material 40 is fixed to the existing vertical frame member 34, and the new vertical frame member 7 is fixed to the reinforcing material 40. In this way, various fittings of the reinforcing material 40 around the periphery of the renovated fitting 1 can be accommodated.

[0044] Figure 6 is a cross-sectional view showing an example of a renovated fixture 1 with the cover 60 removed from the reinforcement material 40, and similar to Figure 4, shows a portion of the renovated fixture 1 including the existing vertical frame material 34 and the new vertical frame material 7. As shown in the figure, here, the existing vertical frame material 34 is installed between the new vertical frame material 7 and the frame 12 of the building 10 in the left-right direction S, and is disposed on the indoor side of the exterior wall 13 of the building 10. The exterior wall 13 of the building 10 is disposed from the existing vertical frame material 34 to a position on the outdoor side of the existing vertical frame material 34.

[0045] The reinforcing material 40 is located on the outdoor side of the existing vertical frame material 34, separated from the exterior wall 13 of the building 10, between the new vertical frame material 7 and the exterior wall 13 of the building 10. When the cover 60 is attached to the reinforcing material 40, the cover 60 comes into contact with the exterior wall 13 of the building 10. In contrast, by removing the cover 60 from the reinforcing material 40, the reinforcing material 40 and the remodeled fixture 1 can be installed without the cover 60 interfering with the exterior wall 13 of the building 10. The tip side portion 52A of the fixing screw 52 is located between the reinforcing material 40 and the exterior wall 13 of the building 10.

[0046] A backup material 14 and a sealant 15 are provided in the area between the reinforcing material 40 and the exterior wall 13 of the building 10. The sealant 15 is made of an amorphous sealing material, is received by the backup material 14, and is filled on the outdoor side of the backup material 14. The area between the reinforcing material 40 and the exterior wall 13 of the building 10 is blocked by the sealant 15 on the outdoor side. A tip side portion 52A of the fixing screw 52 is surrounded by the backup material 14, and is shielded by the sealant 15 on the outdoor side.

[0047] In the remodeled fitting 1 described above, the cover 60 attached to the reinforcing material 40 can prevent the tip side portion 52A of the fixing screw 52 from being exposed. This makes it possible to easily ensure the design and safety of the portion where the new vertical frame member 7 is fixed to the reinforcing material 40. In addition, the cover 60 can be removed from the reinforcing material 40, making it easy to accommodate various fittings of the reinforcing material 40 to the periphery of the remodeled fitting 1. This improves the ease of construction of the remodeled fitting 1. The new vertical frame member 7 can also be reinforced by the reinforcing material 40 to ensure stable installation.

[0048] The cover 60 has an attachment portion 61 and a covering portion 62, and with the attachment portion 61 attached to the reinforcing material 40, the covering portion 62 can reliably cover the tip side portion 52A of the fixing screw 52. The first covering piece 65 and the second covering piece 66 of the covering portion 62 can also reliably cover the tip side portion 52A of the fixing screw 52 in the indoor / outdoor direction T and the left / right direction S. By attaching and detaching the mounting screw 53 that attaches the attachment portion 61 to the reinforcing material 40, the cover 60 can be easily attached to the reinforcing material 40 and removed from the reinforcing material 40. Furthermore, the covering portion 62 can shield the tip side portion 53A of the mounting screw 53 in addition to the tip side portion 52A of the fixing screw 52.

[0049] The steel material of the reinforcing member 40 is, for example, carbon steel, special steel, or stainless steel. In contrast, the reinforcing member 40 is not limited to various steels, and may be made of other metals (for example, aluminum alloys). The cover 60 may be made of various metals (for example, steel, aluminum alloys), or may be made of materials other than metals (for example, synthetic resins). The shape of the cover 60 is not limited to a concave shape, and may be other shapes (for example, a hollow shape with the opening 63 closed). The reinforcing member 40 and the cover 60 may each be manufactured by processing a shaped member (extruded shaped member) formed by extrusion molding. The cover 60 may be removably attached to the reinforcing member 40 by attachment means other than the attachment screw 53 (for example, locking, fitting, adhesion).

[0050] In this embodiment, an example has been described in which the new frame material reinforced by the reinforcement material 40 is the new vertical frame material 7, and the existing frame material covered by the new frame material reinforced by the reinforcement material 40 is the existing vertical frame material 34. In contrast, the new frame material is not limited to the new vertical frame material 7 on the hanging part 25 side of the door body 20, but may be the new vertical frame material 6 on the door end part 24 side of the door body 20, or may be a new frame material (new upper frame material 4, new lower frame material 5) other than the new vertical frame materials 6 and 7. Therefore, the existing frame material is not limited to the existing vertical frame material 34, but may be other existing frame materials (existing vertical frame material 33, existing upper frame material 31, existing lower frame material 32) corresponding to the new frame material. The present invention can be applied to various remodeling fixtures other than remodeling doors (for example, remodeling windows).
