Description

Technical Field

[0001] The present invention relates to a frame profile, a frame, and a method for repairing a frame.

Background Art

[0002] Some of the frame profiles constituting the frame of a fitting have a bridge member formed of a heat insulating material in consideration of heat insulation. The bridge member is provided so as to connect between an indoor metal molded portion formed of a metal such as an aluminum alloy and an outdoor metal molded portion. In a frame to which this type of frame profile is applied, since the space between the indoor metal molded portion and the outdoor metal molded portion is thermally blocked by the bridge member, for example, even when the outdoor temperature is lower than the indoor temperature, It is possible to prevent the occurrence of condensation on the indoor metal molded portion (for example, see Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, the linear expansion coefficients of the metal molded portion and the bridge member constituting the frame profile are different from each other. Therefore, there is a possibility that stress along the longitudinal direction is generated in the bridge member due to the influence of heat such as solar heat or the difference in temperature between seasons, and depending on the usage situation, peeling may occur between the metal molded portion and the bridge member, or the bridge member may shrink with respect to the metal molded portion. For this reason, in a frame profile having a bridge member, there is a concern that the watertightness may be impaired, such as outdoor water entering the indoor side through the gaps in the peeled or shrunk portions.

[0005] In view of the above circumstances, the present invention aims to provide a frame profile, a frame, and a method for repairing a frame that can prevent situations in which watertightness is compromised and improve thermal insulation. [Means for solving the problem]

[0006] To achieve the above objective, the frame profile according to the present invention comprises a first metal formed part and a second metal formed part formed of metal, and a bridge member formed of a heat insulating material, wherein the first metal formed part and the second metal formed part are connected via the bridge member, and a connecting member formed of a heat insulating material is bonded to at least the surface portion extending between the bridge member and the first metal formed part.

[0007] Furthermore, the frame according to the present invention is characterized in that the first metal formed portion and the second metal formed portion of the frame profile described above are arranged side by side in the depth direction and are used as at least a lower frame.

[0008] Furthermore, the method for repairing a frame according to the present invention is a frame profile comprising a frame profile having a first metal formed part and a second metal formed part formed of metal, and a bridge member formed of a heat insulating material, wherein the first metal formed part and the second metal formed part are connected via the bridge member, and the method for repairing a frame profile is characterized by including a step of bonding a connecting member formed of a heat insulating material to at least the surface portion extending between the bridge member and the first metal formed part. [Effects of the Invention]

[0009] According to the present invention, since the bridge material is connected to at least the first metal molded part via an adhesive connecting member, relative movement between the first metal molded part and the bridge material is suppressed. Therefore, even due to the effects of heat such as solar radiation and seasonal temperature fluctuations, it is possible to prevent the bridge material from shrinking relative to the first metal molded part, and to improve thermal insulation while ensuring watertightness.

Embodiments for Carrying out the Invention

[0011] Hereinafter, preferred embodiments of the profile for a frame body, the frame body, and the repair method of the frame body according to the present invention will be described in detail while referring to the accompanying drawings. In the following description, for convenience, the terms "prospective direction" and "search direction" may be used. The prospective direction is a direction along the depth of the frame body, as indicated by arrow A in the figure. A surface along the prospective direction may be referred to as a prospective surface. The search direction is a direction along the up and down perpendicular to the prospective direction when extending along the horizontal direction such as the lower frame. When extending along the vertical direction such as a vertical frame, the horizontal direction perpendicular to the prospective direction is referred to as the search direction. A surface along the search direction may be referred to as a search surface.

[0012] (Embodiment 1) Figure 1 shows a frame according to Embodiment 1 of the present invention. The frame 10 illustrated here, although not explicitly shown in the figure, is applicable to a sliding window in which the interior sash on the inside and the exterior sash on the outside are arranged to slide left and right, and is constructed by assembling an upper frame 11, a lower frame (frame profile) 12, and left and right vertical frames 13 around the perimeter. As shown in Figures 2 to 4, the lower frame 12 of the frame 10 has an exterior metal formed part 12A, an interior metal formed part 12B, and a bridge member 12C. The two metal formed parts 12A and 12B are extruded profiles formed from a metal such as an aluminum alloy, and are arranged side by side in the depth direction. Each of the individual metal formed parts 12A and 12B is provided with a guide rail 12a and a bridge mounting groove 12b, respectively. The guide rail 12a extends along the length of the lower frame 12 to guide the sliding of the sash, and is provided to protrude inward from the inner circumference portion of each metal molded part 12A, 12B. The bridge mounting groove 12b is provided so as to open to each other at the opposite ends of the metal molded part 12A on the exterior side and the metal molded part 12B on the interior side. Each bridge mounting groove 12b is formed in a dovetail shape with an opening width narrower than the interior width. The bridge material 12C is molded from a resin with heat insulating properties, and connects the metal molded part 12A on the exterior side and the metal molded part 12B on the interior side by attaching its end to the bridge mounting groove 12b. The metal molded part 12A on the exterior side and the metal molded part 12B on the interior side, connected via the bridge material 12C, have a gap between them, and are physically and thermally isolated from each other. Reference numeral 12D in Figure 2 indicates a resin lower frame cover provided between the guide rails 12a.

[0013] The exterior metal molded portion 12A and the interior metal molded portion 12B are each provided with adhesive flat surfaces 12c. The adhesive flat surfaces 12c are horizontal surfaces located on substantially the same plane. These adhesive flat surfaces 12c are located on the same plane as the inner circumferential surface 12d of the bridge material 12C.

[0014] Also, as shown in FIGS. 3 to 6, a connecting sheet (connecting member) 20 and a water stop tape (thin film member) 30 are adhered between the outdoor metal forming part 12A and the indoor metal forming part 12B, respectively. The connecting sheet 20 and the water stop tape 30 are each formed of a resin having heat insulation properties. The connecting sheet 20 has a thickness of, for example, about 120 μm to 1 mm, and is configured to have a length (for example, 200 mm) that can be disposed only at both ends along the longitudinal direction of the lower frame 12. The water stop tape 30 is formed of a resin that is more flexible than the connecting sheet 20, and has a length greater than the mutual interval of the connecting sheets 20 at both ends. The connecting sheet 20 and the water stop tape 30 applied in the first embodiment are configured to have a width that can be disposed over the flat bonding surfaces 12c provided on the two metal forming parts 12A and 12B, and the width of the water stop tape 30 is larger than the width of the connecting sheet 20. Although not shown in the figure, the water stop tape 30 has an adhesive layer on the back surface, and is adhered to a portion extending over the flat bonding surface 12c provided on the outdoor metal forming part 12A, the inner peripheral surface 12d of the bridge member 12C, and the flat bonding surface 12c provided on the indoor metal forming part 12B through this adhesive layer. On the other hand, the connecting sheet 20 is adhered to the flat bonding surface 12c provided on the outdoor metal forming part 12A, the inner peripheral surface 12d of the bridge member 12C, the flat bonding surface 12c provided on the indoor metal forming part 12B, and the end surface of the water stop tape 30 through an adhesive E. The adhesive E may be applied to the flat bonding surfaces 12c of the metal forming parts 12A and 12B, the inner peripheral surface 12d of the bridge member 12C, and the surface of the water stop tape 30, or may be applied to the back surface of the connecting sheet 20. The connecting sheet 20 is disposed so as to overlap the water stop tape 30 by about 3 to 5 mm, respectively.

[0015] In the lower frame 12 configured as described above, the outdoor metal molded part 12A and the indoor metal molded part 12B are connected via a bridge material 12C formed from insulating material, which is advantageous in terms of thermal insulation. Moreover, since the bridge material 12C is connected to the outdoor metal molded part 12A and the indoor metal molded part 12B via an adhesive connecting sheet 20, relative movement between these metal molded parts 12A, 12B and the bridge material 12C is suppressed. Therefore, even under the influence of heat such as solar radiation and seasonal temperature fluctuations, it is possible to prevent the bridge material 12C from shrinking relative to the metal molded parts 12A and 12B, thereby improving thermal insulation while ensuring watertightness. In addition, waterproof tape 30 is adhered to the portion of the connecting sheet 20 at both ends, spanning the outdoor metal molded part 12A and the indoor metal molded part 12B. Therefore, it is possible to prevent the bridge material 12C from being directly exposed to sunlight, and to prevent contact with outdoor water such as rainwater, thereby preventing deterioration of the bridge material 12C. Furthermore, even if a gap occurs between the metal molded parts 12A, 12B and the bridge material 12C due to delamination caused by the shrinkage of the bridge material 12C, the gap will be sealed by the connecting sheet 20 and the waterproofing tape 30, so there is no risk of outdoor water entering the interior. In addition, since the connecting sheet 20 and the waterproofing tape 30 are made of a resin with heat insulating properties, there is no concern that the heat insulating properties of the lower frame 12 will be impaired.

[0016] In the above-described embodiment 1, a highly flexible waterproof tape 30 is adhered to the overlapping portions of the connecting sheets 20 at both ends, making it possible to cover the entire surface of the bridge material 12C without impairing workability. However, the present invention is not limited to this, and as shown in modified example 1 in Figures 7 and 8, it is also possible to provide the connecting sheet 20 along the entire length of the lower frame 12. According to this modified example 1, relative movement between the metal molded parts 12A, 12B and the bridge material 12C is suppressed along the entire length of the lower frame 12, making it possible to more reliably prevent shrinkage of the bridge material 12C.

[0017] Furthermore, in the above-described embodiment 1, the connecting sheet 20 is bonded across the outdoor metal molded portion 12A and the indoor metal molded portion 12B. However, as shown in modified example 2 in Figure 9, if a flat surface 12c for bonding cannot be secured on the indoor metal molded portion 12B, the connecting sheet 20 may be bonded only between the outdoor metal molded portion 12A and the bridge material 12C. Conversely, the connecting sheet 20 may be bonded only between the indoor metal molded portion 12B and the bridge material 12C. The same applies when using waterproof tape 30.

[0018] Furthermore, although the first embodiment described above illustrates a frame 10 applicable to a sliding window, it is also possible to apply it to other types of window frames 10.

[0019] (Embodiment 2) Figure 10 shows a frame repair method according to Embodiment 2 of the present invention. The object to be repaired as exemplified here is a lower frame 12 having an outdoor metal molded part 12A, an indoor metal molded part 12B, and a bridge material 12C formed from thermal insulation material, similar to the lower frame 12 applied to the frame 10 of Embodiment 1. Although the lower frame 12 is provided with a resin lower frame cover 12D between the guide rails 12a, as shown in Figures 11 and 12, the bridge material 12C has already shrunk over time, creating a gap F at the end between the outdoor metal molded part 12A and the indoor metal molded part 12B. In this Embodiment 2, the same reference numerals are used for components that are the same as in Embodiment 1.

[0020] When repairing the lower frame 12, after removing the shoji screen or screen door (not shown) from the frame 10, the lower frame cover 12D is removed from the lower frame 12 to expose the inner surface, as shown in Figures 10(a) and 10(b). Next, the adhesive flat surfaces 12c of the metal molded parts 12A and 12B and the inner surface 12d of the bridge material 12C are polished using a polishing tool such as a buff, and the waterproof tape 30 is first adhered to the polished areas. The waterproof tape 30 is adhered to the portion that spans the adhesive flat surface 12c on the metal molded part 12A on the exterior side, the inner surface 12d of the bridge material 12C, and the adhesive flat surface 12c on the metal molded part 12B on the interior side. As shown in Figures 11 to 13, the waterproof tape 30 is not adhered to both ends of the lower frame 12.

[0021] Subsequently, a heat-insulating filler (insulating material) 40 is filled into the gap F between the metal molded parts 12A and 12B. Preferably, the inner surface of the filler 40 is molded to be on the same plane as the adhesive flat surface 12c of the metal molded parts 12A and 12B.

[0022] Next, as shown in Figures 10(c) and 10(d), the connecting sheet 20 is bonded to the adhesive flat surface 12c provided on the exterior metal molded part 12A, the inner circumferential surface 12d of the bridge material 12C, the adhesive flat surface 12c provided on the interior metal molded part 12B, the end surface of the waterproof tape 30, and the inner circumferential surface of the filler 40 via adhesive E. The adhesive E may be applied to the adhesive flat surfaces 12c of the metal molded parts 12A and 12B, the inner circumferential surface 12d of the bridge material 12C, the surface of the waterproof tape 30, or it may be applied to the back surface of the connecting sheet 20. After bonding the connecting sheet 20, the lower frame cover 12D, the shoji screen, and the screen door can be put back in place as shown in Figure 10(e).

[0023] As described above, in the lower frame 12 of the repaired frame 10, as shown in Figures 11(b), 12, and 13, the gap F that existed between the outdoor metal molded part 12A and the indoor metal molded part 12B is sealed by the filler 40, thus preventing outdoor water from entering the indoor side through the gap F. Furthermore, since the bridge material 12C is connected to the outdoor metal molded part 12A and the indoor metal molded part 12B via the bonded connecting sheet 20, relative movement between these metal molded parts 12A, 12B and the bridge material 12C is suppressed. Therefore, even due to the effects of heat such as solar heat applied after repair and seasonal temperature fluctuations, it is possible to prevent the bridge material 12C from shrinking relative to the metal molded parts 12A and 12B. In addition, waterproof tape 30 is bonded to the parts of the connecting sheet 20 that span across the outdoor metal molded part 12A and the indoor metal molded part 12B. Therefore, even if a gap develops between the bridge material 12C and the metal molded parts 12A and 12B over time, the waterproofing tape 30 will seal it, restoring watertightness. In addition, since the connecting sheet 20 and the waterproofing tape 30 are made of a resin with heat insulating properties, there is no concern that the heat insulating properties of the lower frame 12 will be impaired.

[0024] In this second embodiment as well, as shown in the modified example 3 in Figures 14 to 16, it is possible to provide the connecting sheet 20 along the entire length of the lower frame 12. Furthermore, if a flat surface 12c for adhesion cannot be secured in either of the metal molded parts, the connecting sheet 20 may be adhered only between the other metal molded part and the bridge material 12C. The same applies when using waterproof tape 30.

[0025] In the embodiments described above, examples are shown where the material is applied to the lower frame 12, but it may also be applied to the vertical frame 13 or the upper frame 11. Furthermore, although a sheet-like material is used as the connecting member, it does not necessarily have to be in the form of a sheet. In addition, although a waterproof tape with an adhesive layer on the back surface is shown as the thin film member, it may also be bonded by applying an adhesive, similar to the connecting member.

[0026] As described above, the frame profile according to the present invention comprises a first metal formed part and a second metal formed part formed of metal, and a bridge member formed of a heat insulating material, wherein the first metal formed part and the second metal formed part are connected via the bridge member, and a connecting member is bonded to at least the surface portion extending between the bridge member and the first metal formed part. According to this invention, since the bridge material is connected to at least the first metal molded part via an adhesive connecting member, relative movement between the first metal molded part and the bridge material is suppressed. Therefore, even due to the effects of heat such as solar radiation and seasonal temperature fluctuations, it is possible to prevent the bridge material from shrinking relative to the first metal molded part, and to improve thermal insulation while ensuring watertightness.

[0027] Furthermore, the present invention is characterized in that, in the frame profile described above, the connecting member is provided at least at both ends of the longitudinal side. According to this invention, relative movement between the first metal forming portion and the bridge material is suppressed at least at both ends, thereby more reliably preventing the bridge material from shrinking relative to the first metal forming portion.

[0028] Furthermore, the present invention is characterized in that, in the frame profile described above, the connecting members are provided only at both ends of the longitudinal side, and a thin film member having greater flexibility than the connecting members is bonded to the surface portion of the connecting members that extends between the bridge material and the first metal molded portion. According to this invention, relative movement between the first metal formed part and the bridge material is suppressed at both ends, so that the bridge material does not shrink relative to the first metal formed part can be prevented more reliably. Furthermore, since a thin film member that is more flexible than the connecting members is provided between the connecting members, the entire surface of the bridge material located between the connecting members can be covered without impairing workability.

[0029] Furthermore, the present invention is characterized in that, in the frame profile described above, the connecting member is formed from a heat insulating material and is provided on the surface portion extending across the first metal formed portion and the second metal formed portion. According to this invention, relative movement between the bridge material and the second metal forming part is suppressed, making it possible to more reliably prevent the bridge material from shrinking relative to the first metal forming part.

[0030] Furthermore, the frame according to the present invention is characterized in that the first metal formed part and the second metal formed part of the frame profile described above are arranged side by side in the depth direction and are used as at least a lower frame. According to this invention, water intrusion from the outside to the inside via the lower frame is prevented, thereby improving heat insulation while ensuring watertightness.

[0031] Furthermore, the frame repair method according to the present invention is a frame profile comprising a frame profile having a first metal formed part and a second metal formed part formed of metal, and a bridge material formed of a heat insulating material, wherein the first metal formed part and the second metal formed part are connected via the bridge material, and the method is characterized by including a step of bonding a connecting member to at least the surface portion extending between the bridge material and the first metal formed part. According to this invention, relative movement between the first metal formed part and the bridge material is suppressed in the frame profile after repair, preventing the bridge material from shrinking relative to the first metal formed part, and making it possible to improve heat insulation while ensuring watertightness.

[0032] Furthermore, the present invention is characterized in that, in the frame repair method described above, the step of filling the gap between the first metal molded part and the second metal molded part with heat insulating material before bonding the connecting member. According to this invention, even if gaps occur between metal molded parts due to the shrinkage of the bridge material, watertightness can be restored by repair, and further shrinkage of the bridge material can be prevented.
