Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the fitting described in Patent Document 1, it has a structure having a heat transfer path from the metal frame located on the outdoor side - the connecting member - to the frame member located on the indoor side. That is, there is a problem that dew condensation is likely to occur on the frame member due to heat transfer along the heat transfer path. Here, a structure in which a heat insulating member such as resin is interposed between the metal frame and the connecting member to block heat transfer from the metal frame to the connecting member by the heat insulating member is also conceivable. However, in such a structure, since a heat insulating member is interposed between the metal frame and the connecting member, it is difficult to maintain the mounting accuracy between the metal frame and the frame member. In particular, when a resin material is used for the heat insulating member, rattling occurs due to creep of the heat insulating member.

[0005] In view of the above circumstances, an object of the present invention is to provide a fitting that can suppress condensation of the frame member while maintaining the mounting accuracy between the metal frame and the frame member.

Means for Solving the Problems

[0006] To achieve the above object, a fitting according to the present invention includes a metal frame constituting a frame body provided in an opening of a building, a frame member provided on the indoor side of the metal frame, and a connecting member connecting the metal frame and the frame member. The connecting member is constituted by a heat-insulating profile having a first connecting portion connected to the metal frame, a second connecting portion connected to the frame member, and a heat-insulating member provided between the first connecting portion and the second connecting portion.

Effects of the Invention

[0007] According to the fitting of the present invention, it is possible to suppress condensation of the frame member while maintaining the mounting accuracy between the metal frame and the frame member.

The second engaging portion 524 is provided on the outdoor-side edge of the frame member main body 521 and is a groove portion opening to the outdoor side. The receiving portion 525 extends in the finding direction from a position on the prospective surface on the outer peripheral side of the frame member main body 521 that is more outdoor-side than the first engaging portion 523 toward the outer peripheral side.

[0031] The material of the frame member 50 will be described later.

[0032] [Configuration of the connecting member] Next, with reference to FIG. 3, the configuration of the connecting member 60 will be described. The connecting member 60 includes an upper connecting member 61 corresponding to the upper frame 11 and the upper edge member 51, a lower connecting member 62 corresponding to the lower frame 12 and the lower edge member 52, a door tip connecting member 63 corresponding to the door tip frame 13 and the door tip edge member 53, and a suspension end connecting member 64 corresponding to the suspension end frame 14 and the suspension end edge member 54. Each of these connecting members 61 to 64 has a substantially identical cross-sectional shape over the entire length. Further, each of these connecting members 61 to 64 has the same configuration. Therefore, hereinafter, among the connecting members 61 to 64, the configuration of the lower connecting member 62 will be described with reference to FIG. 3.

[0033] The lower connecting member 62 is composed of a heat-insulating profile having a first connecting portion 621, a second connecting portion 622, and a heat-insulating member 623. The first connecting portion 621 is composed of an extruded profile made of a metal such as aluminum and has a substantially identical cross-sectional shape over the entire length.

The second engaging piece part 622e is a part that extends in an inclined state from the edge on the indoor side of the frame member side connection piece 622b toward the outer peripheral side. In this second engaging piece part 622e, a claw part 622f protruding toward the outer peripheral side is provided at the edge on the indoor side and outer peripheral side.

[0035] The heat insulating member 623 is composed of a heat insulating material such as urethane resin, and connects the first and second connecting parts 621 and 622 in a heat-insulated state. In the present embodiment, the heat insulating member 623 is interposed between the first groove part 621c and the second groove part 622c. That is, the heat insulating member 623 connects the first and second connecting parts 621 and 622 along the inner and outer peripheral directions of the frame body 10.

[0036] And the metal lower frame 32 and the lower frame member 52 are connected by the lower connecting member 62 as shown below. First, the operator screws the frame side connection piece 621a to the connection piece 323b. When connecting the metal upper frame 31 and the upper frame member 51 by the upper connecting member 61, the frame side connection piece 621a is screwed to the connection piece 313b. Also, when connecting the metal door tip frame 33 and the door tip frame member 53 by the door tip connecting member 63, the frame side connection piece 621a is screwed to the connection piece 334b. Further, when connecting the metal hanging end frame 34 and the hanging end frame member 54 by the hanging end connecting member 64, the frame side connection piece 621a is screwed to the connection piece 344b.

[0037] Next, the operator fits the first engaging piece portion 622d into the second engaging portion 524, inserts the tip of the second engaging piece portion 622e into the U-shaped space surrounded by the first engaging portion 523 and the frame member body 521, and locks the claw portions 523a and 622f together. Through the above operations, the metal lower frame 32 and the lower frame member 52 are connected by the lower connecting member 62. In this state, the lower mounting plate portion 423 of the resin lower frame 42 and the inner peripheral side surface of the frame member body 521 are flush with substantially zero step.

[0038] [Regarding the material of the frame member] As the material of the frame member 50, a non-insulating material can be adopted. Here, examples of the non-insulating material include aluminum (thermal conductivity of about 160 [W / (m / K)]), steel (thermal conductivity of about 50 [W / (m / K)]), stainless steel (thermal conductivity of about 17 [W / (m / K)]), concrete (thermal conductivity of about 1.6 [W / (m / K)]), and marble (thermal conductivity of about 1.0 [W / (m / K)]). In addition to the materials listed above, other materials with a thermal conductivity ranging from about 1.0 [W / (m / K)] to about 160 [W / (m / K)] can be adopted as the material of the frame member 50.

[0039] (Other embodiments) So far, the embodiments for carrying out the present invention have been described, but the present invention should not be limited only by the above-described embodiments. In the above-described embodiment, the fitting 1 according to the present invention is a vertically sliding window, but it is not limited thereto, and it may be configured as various fittings such as a single-sliding window, a double-sliding window, a sliding window, a sash window, and a FIX window.

[0040] In the above-described embodiment, the following modification examples may be adopted. FIG. 4 is a diagram for explaining a modification example of the embodiment. Specifically, FIG. 4 is a longitudinal sectional view according to this modification example corresponding to FIG. 1. In the above-described embodiment, a part of the frame member 50 may be sandwiched between the resin frame 40 and the connecting member 60. Note that FIG. 4 shows a state in which a part of the lower frame member 52 is sandwiched between the resin lower frame 42 and the lower connecting member 62. Specifically, the outdoor-side portion of the frame member main body 521 is sandwiched between the lower mounting plate portion 423 and the second connecting portion 622.

[0041] The fitting according to the present invention includes a metal frame that constitutes a frame body provided at an opening of a building, a frame member provided on the indoor side of the metal frame, and a connecting member that connects the metal frame and the frame member. The connecting member is constituted by a heat-insulating profile having a first connecting portion connected to the metal frame, a second connecting portion connected to the frame member, and a heat-insulating member provided between the first connecting portion and the second connecting portion.

[0042] In the present invention, the metal frame and the frame member are connected by a connecting member constituted by a heat-insulating profile. That is, the heat transfer path from the metal frame located on the outdoor side to the frame member located on the indoor side can be blocked by the connecting member, and dew condensation on the frame member can be suppressed. Further, since the heat transfer path is not blocked by interposing a heat-insulating member between the metal frame and the connecting member, creep of the heat-insulating member does not occur, and the mounting accuracy between the metal frame and the frame member can be maintained well. Therefore, according to the fitting of the present invention, it is possible to suppress dew condensation on the frame member while maintaining the mounting accuracy between the metal frame and the frame member.

[0043] Further, the present invention is characterized in that, in the above-described fitting, the frame body includes the metal frame and a resin frame provided between the metal frame and the frame. In the present invention, the frame body is a composite frame body of metal and resin including a metal frame and the above-described resin frame. Therefore, the heat insulation can be improved.

[0044] Further, the present invention is characterized in that, in the fitting described above, a part of the frame member is sandwiched between the resin frame and the connecting member. By the way, when adopting a structure in which the inner peripheral side surfaces of the resin frame and the frame member are flush with substantially zero step, the step may not become zero and the appearance quality may be impaired. In the present invention, a part of the frame member is sandwiched between the resin frame and the connecting member, and the inner peripheral side surfaces of the resin frame and the frame member are provided with a step in advance. Therefore, the appearance quality is not impaired.

[0045] Further, the present invention is characterized in that, in the fitting described above, the first connecting portion and the second connecting portion are connected by the heat insulating member along the inner and outer circumferential directions of the frame body. In the present invention, the heat insulating member connects the first and second connecting portions along the inner and outer circumferential directions of the frame body. Therefore, the position where the heat transfer path from the metal frame located on the outdoor side to the frame member located on the indoor side is blocked by the heat insulating member can be positioned on the outdoor side, and the heat insulation performance can be improved.

[0046] Further, the present invention is characterized in that, in the fitting described above, the frame member is made of a metal material. In the present invention, the frame member is made of a metal material that is likely to cause condensation if the heat transfer path from the metal frame located on the outdoor side to the frame member located on the indoor side is not blocked. Therefore, the effect of suppressing condensation on the frame member can be preferably realized.
