  In the continuous window sash shown in FIGS. 11 and 12, the window frames are connected to each other (continuous window or step window), and an internal member (covering member 129, 429) such as wood is disposed on the indoor side. It has the effect of improving the appearance from the inside and suppressing the transfer of heat from the outdoor side to the indoor side. However, in FIG.11 and FIG.12, the length of the prospective direction of the window frames connected is the same, Therefore, the bending part 129c, 429c and the frame 415,455 of a wooden internal member (cover member 129,429) are the same. , 115 have the same length in the prospective direction. Therefore, if the window frames to be connected have the same length in the prospective direction, wooden internal members (cover members 129 and 429 and picture frames 415, 455 and 115) can be used. If the lengths in the prospective direction of the frames are different, it is difficult to use the wooden internal members (the covering members 129 and 429 and the frames 415, 455, and 115) shown in FIGS.

  The present invention has been made in view of the above circumstances, and even when the lengths of the prospective directions of the connected window frames are the same, even when the lengths of the prospective directions of the connected window frames are different, the window frames. An object of the present invention is to provide a sash connection structure that enables connection between each other, ensures the appearance of the indoor side, and prevents heat from being transmitted from the outdoor side to the indoor side.

  In order to achieve the above-mentioned object, the invention according to claim 1 is the opposite of the connecting member which is a vertical or invisible connection member for connecting the window frames to the side facing the finding surface of the window frame to be connected. The window to be connected in a direction along a prospective direction of the window frame connected by the connecting member of the first inner frame provided on the outer side of the connecting member and the first inner frame. A bent portion of the first inner frame body extending toward the frame side so as to oppose each other and sandwiching the connecting member; and provided between the first inner frame body and the connecting member; And a support member to which the one internal frame is attached.

  Therefore, according to the first aspect of the present invention, the supporting member is provided between the connecting member that is vertical or seamless and the first inner frame, and the first inner frame is attached to the connecting member. Since the bent part of the first inner frame extends from the inner frame in a direction along the window or the prospective direction of the window frame, the connecting member is surrounded by the first inner frame on the indoor side. It is possible to make it difficult to transfer heat from the outdoor side to the indoor side, and the connecting member protruding to the indoor side is surrounded by the first internal frame, It becomes possible to make the connecting member invisible.

  Moreover, in addition to the structure of Claim 1, invention of Claim 2 is mutually opposing to the said window frame side in the direction along the prospective direction of the said window frame connected by the said connection member. The lengths along the prospective direction of the window frame of the extending bent portions of the first inner frame body are the same or different.

  Therefore, according to invention of Claim 2, the length of the prospective direction is the same by making the length along the prospective direction of the said window frame the same between the bending parts of a 1st internal frame. The portion of the connecting members that are connected to each other along the prospective direction of the window frames to be joined on the indoor side is surrounded (covered) by the bent portion of the first inner frame body so that the connecting member cannot be seen from the indoor side, and the length in the prospective direction Allows connection of window frames of the same length. Moreover, the indoor side of the connection member which connected the window frames from which the length of a prospective direction differs by making the length along the prospective direction of the said window frame differ between the bending parts of a 1st internal frame body Enclose the part along the prospective direction of the window frames to be connected with the bent part of the first internal frame body so that the connecting member cannot be seen from the indoor side, and the window frames with different lengths in the prospective direction can be connected To.

  Further, the invention according to claim 3 is the configuration according to claim 1 or 2, in addition to both ends of the bent portion of the first inner frame body that are opposed to each other and extend while sandwiching the connecting member.

Since the plate-like second inner frame is provided adjacent to each other, the connecting member is connected to the first inner frame on the indoor side regardless of whether the lengths in the prospective direction of the window frames to be connected are the same or different. The body and the second inner frame are surrounded (covered), making it difficult to transfer heat from the outdoor side to the indoor side and making the connecting member invisible from the indoor side. It becomes possible. Further, the second inner portion of the first inner frame body is formed in a flat plate shape along the prospective direction of the window frame to be connected to one of the end portions of the bent portion that are opposed to each other and extend while sandwiching the connecting member. Since the frame bodies are provided adjacent to each other, the connecting member is surrounded (covered) by the first inner frame body and the second inner frame body on the indoor side, and heat is transferred from the outdoor side to the indoor side. It becomes possible to make it difficult to transmit and to make the connecting member invisible from the indoor side.

  According to a fourth aspect of the present invention, in addition to the configuration according to any one of the first to third aspects, the end of the bent portion of the first inner frame that extends while sandwiching the connecting member so as to face each other. Each of the flat plate-like second inner frames provided adjacent to the part has the same or different length along the prospective direction of the window frame to be connected.

  Therefore, according to the fourth aspect of the present invention, each flat second inner portion provided adjacent to the end portion of the bent portion of the first inner frame that extends opposite to each other with the connecting member interposed therebetween. Since the frame bodies have the same or different lengths along the prospective direction of the window frames to be coupled, various second flat-shaped interiors depending on the length of the window frames to be coupled in the prospective direction. By selecting an appropriate flat internal frame from the frame, the connecting member is enclosed by the first internal frame and the second internal frame on the indoor side, and heat is transferred from the outdoor side to the indoor side. It becomes possible to make it difficult to make the connection member invisible from the indoor side.

  Furthermore, in the invention described in claim 5, in addition to the structure described in any one of claims 1 to 4, a support member is provided between the flat plate-like second inner frame body and the connecting member. The plate-shaped second inner frame is attached to the connecting member.

  Therefore, according to the fifth aspect of the present invention, the support member is provided between the flat plate-like second inner frame and the connecting member, and is attached to the connecting member and the flat plate-like second inner frame. Therefore, it becomes possible to attach the flat plate-like second inner frame to the connecting member, and to make the connecting member invisible from the indoor side.

  According to a sixth aspect of the present invention, in addition to the configuration according to any one of the first to fifth aspects, the first inner frame provided on one of the connecting members where the connecting members intersect with each other. A plurality of plate-like shapes provided on the end face side of the body adjacent to the end of the bent portion of the first inner frame provided on the other connecting member along the longitudinal direction of the other connecting member Is sandwiched between the second inner frames.

  Therefore, according to the sixth aspect of the present invention, where the connecting members cross each other, the end surface side of the first inner frame provided on one of the connecting members extends along the longitudinal direction of the other connecting member. Since it is sandwiched between a plurality of flat second inner frames provided adjacent to the end of the bent portion of the first inner frame provided on the other connecting member, it is provided on one connecting member. The gap between the end face of the first inner frame body and the plurality of flat second inner frame bodies provided adjacent to the end of the bent portion of the first inner frame body provided on the other connecting member Can be made invisible from the indoor side.

  Furthermore, in the invention described in claim 7, in addition to the structure described in any one of claims 1 to 6, a distal end portion of the connecting member is provided by interposing a heat insulating material between the main body portion of the connecting member. Is attached, and the tip of the connecting member is covered with the window frame to be connected.

  Therefore, according to the invention of claim 7, since the heat insulating material is interposed between the main body portion of the connecting member and the distal end portion of the connecting member facing the outdoor member to which the window frame is attached, Heat becomes difficult to transfer from the outdoor side to the indoor side. In addition, the front end of the connecting member is covered with a window frame to be connected, so that the front end of the connecting member does not directly touch the outside air, thereby making it difficult to transfer heat from the outdoor side to the indoor side. It becomes possible to make the front-end | tip part of a connection member invisible from the outside.

  According to the present invention, by using two types of internal frames (a small internal frame having a substantially U-shaped cross section and a flat internal frame), when connecting window frames to a structure, Therefore, the connecting member is not visible, and the appearance on the indoor side is not impaired. In addition, the two types of internal frames (small internal frame with a substantially U-shaped cross section, flat plate-shaped internal frame) are made of wood or resin and are made of a different material from the connecting member. Heat can be made difficult to transfer indoors.

  In particular, when connecting the window frames, the lengths in the expected direction of the window frames to be connected are different, and even if the connecting member comes out on the indoor side, a flat inner frame body is used, so that the connecting member can be connected from the indoor side. It is not visible and the interior appearance is not impaired. Since this flat inner frame is a simple plate-like member, the machining surface is easy, and since there are no special machining parts such as notches, it is hard to break and is stable in strength. Moreover, since the heat insulating material is interposed in the prospective direction of the connecting member, it is difficult to transfer heat from the outdoor side to the indoor side.
