It is like that.

JP 2003-27809 A

However, in the raising and lowering window described in Patent Document 1, since the projecting pieces that are formed in the vertical frame and partition the indoor and outdoor shoji are provided continuously in the vertical direction, in the state that the shoji is closed, Approximately half of the side is exposed to the outdoor space, and approximately half of the upper side is exposed to the indoor space. For this reason, the projecting piece becomes a thermal bridge, and the heat insulating performance of the window cannot be sufficiently secured, and there is a problem that the projecting piece exposed to the indoor side is condensed particularly in winter.
Moreover, since the airtight material slides into contact with the projecting piece as the movable shoji opens and closes, the operating force required for opening and closing, particularly the upward operating force for opening the movable shoji, increases, and the operability deteriorates. There is also a problem.

  The objective of this invention is providing the fitting which can ensure sufficient heat insulation performance and favorable operativity.

  The joinery of the present invention includes a window frame having an upper frame, a lower frame, and left and right vertical frames, and at least a pair of indoor and outdoor shojis supported so as to be slidable in the window frame. At least one of the shojis is a movable shoji that is provided so as to be slidable and openable. Of the upper, lower, left and right frame members of the window frame, each of the pair of upper and lower frame members or the pair of left and right frame members includes the indoor An indoor / outdoor rail portion for guiding an external shoji is provided, and an auxiliary frame material is attached between the indoor / outdoor rail portions along the frame material, and the auxiliary frame material is in the closed state. The outdoor side auxiliary frame material along the outdoor side of the indoor side shoji, and the indoor side auxiliary frame material along the indoor side of the outdoor side shoji in the closed state, between these indoor and outdoor auxiliary frame materials , The summing part auxiliary member is interposed, the outdoor auxiliary frame material, the chamber A side auxiliary frame member and a summing part auxiliary member are continuously arranged in a substantially straight line, and the indoor side shoji can contact the outdoor side auxiliary frame member and the summing part auxiliary member and the indoor side auxiliary member. An airtight material that cannot be brought into contact with the frame material is provided, and the outdoor shoji is provided with an airtight material that can be brought into contact with the indoor auxiliary frame material and the summing unit auxiliary member and cannot be contacted with the outdoor auxiliary frame material. Is provided.

Here, as a fitting, a sliding door such as a sliding window can be slidably opened and closed to the left and right. In this case, a pair of upper and lower frame members (upper frame and lower frame) are provided with a rail portion and an auxiliary. A frame member may be provided, and a shoji can be slidably opened and closed like a raising and lowering window. In this case, a rail part and an auxiliary frame are provided on a pair of left and right frame members (left and right vertical frames). Materials are provided.
Moreover, as a shoji, what is necessary is just to be equipped with a pair of 2 shoji of indoor and outdoor (left-right or up-down), and it may be comprised from 3 or more shoji.

According to the present invention described above, the pair of frame members (upper frame and lower frame, or left and right vertical frames) that guide the indoor and outdoor shojis in the four-round window frame partition the shojis between the rail portions, that is, indoor and outdoor. By attaching an auxiliary frame material to the position and contacting the airtight material of the shoji with the auxiliary frame material, the airtightness of the joinery with the shoji being closed can be secured.
In addition, the auxiliary frame material is composed of a separate member from the window frame and is attached to the window frame, and is divided into an outdoor auxiliary frame material and an indoor auxiliary frame material, and a summing unit auxiliary member is interposed therebetween. By mounting, the heat conduction between the window frame and the auxiliary frame material and the heat conduction between the auxiliary frame materials are suppressed, and the heat insulating performance of the joinery can be improved.
Furthermore, the airtight material of the indoor shoji is not in contact with the indoor auxiliary frame material, and the airtight material of the outdoor shoji is not in contact with the outdoor auxiliary frame material. Since the contact length between the auxiliary frame member and the auxiliary frame member is gradually shortened, the operation force for opening the shoji can be reduced, and the operability can be improved. In particular, when the joinery is a raising / lowering window, the operation force when lifting and opening the lower shoji can be reduced, which is effective.

In this case, in the joinery of the present invention, the upper, lower, left, and right frame members of the window frame include an indoor member that supports the indoor shoji, an outdoor member that supports the outdoor shoji, and these indoor and outdoor members. The auxiliary frame member straddles the indoor member and the outdoor member in the pair of frame members facing each other and covers the inner side in the direction of finding the heat insulating member. Are preferably attached.
According to such a configuration, in the heat insulating sash having the indoor member, the outdoor member, and the heat insulating member, the window frame is configured, and the auxiliary frame material as described above is attached so as to cover the inside of the heat insulating member in the finding direction. Thus, the heat insulation performance can be further improved, and the design of the joinery can be improved.

Further, in the joinery of the present invention, the auxiliary frame member has a finding surface portion extending in the finding direction and an inclined surface portion continuous to the inner end of the finding surface portion in the finding direction, and is formed in a substantially triangular shape in section. The indoor side auxiliary frame member is disposed with the finding surface portion facing the outdoor side and the inclined surface portion facing the indoor side, and the outdoor side auxiliary frame member is directed with the finding surface portion facing the indoor side and the inclined surface portion facing the room. It is preferable that it is arranged toward the outside.
According to such a configuration, the indoor auxiliary frame material and the outdoor auxiliary frame material are configured by reversing and arranging the members having the finding surface portion and the inclined surface portion and having a substantially triangular cross section, The airtight material can be brought into contact with the finding surface portion and the airtight material can be prevented from coming into contact with the inclined surface portion, and the parts can be shared.

Moreover, in the joinery of this invention, it is preferable that the said auxiliary | assistant frame material has an indoor member, an outdoor member, and the heat insulation member which connects these indoor members and an outdoor member.
According to such a configuration, heat conduction inside and outside the auxiliary frame material itself is also suppressed, so that the heat insulation performance can be further improved.

In the joinery of the present invention, it is preferable that the shoji is composed of two upper and lower shojis, and the auxiliary frame member is attached to the left and right vertical frames.
According to such a structure, the raising / lowering window which has the above-mentioned effect can be comprised. And in the lower shoji of a raising / lowering window, since the operation force at the time of opening operation can be made small, operativity can be made favorable, or even if a lower shoji is enlarged, operativity can be prevented from being impaired.

Here, if each member 14A, 14B, 15 is made of, for example, a resin, the effect of suppressing heat conduction is increased compared to the case of being made of metal. Further, since the upper attachment 14A, the lower attachment 14B, and the airtight member 151 are divided from each other, heat conduction between the members 14A, 14B, and 15 is suppressed. Therefore, the heat insulation performance of the raising / lowering window 1 can be improved by suppressing the heat conduction between the room and the outside through the window frame 10.

(3) Furthermore, since the airtight material 332A of the lower shoji 30 does not contact the upper attachment 14A, and the airtight material 231A of the upper shoji 20 does not contact the lower attachment 14B, as the shoji is released The contact length between the airtight members 332A and 231A and the upper or lower attachments 14A and 14B is gradually shortened, the operating force for opening the shoji can be reduced, and the operability can be improved. In particular, the lower shoji 30 can reduce the operating force when lifted and opened, so that the operability is improved by reducing the operating force, or the operability is impaired even when the lower shoji 30 is enlarged. I can not.

(4) In addition, in the heat insulating sash in which the frame material of the window frame 10 and the upper and lower shojis 20 and 30 includes an indoor member, an outdoor member, and a heat insulating member, the inner side in the direction in which the heat insulating member 136 of the vertical frame 13 is found. Since the upper attachment 14A, the lower attachment 14B, and the airtight member 151 are attached so as to cover the surface, the heat insulation performance can be further improved and the design can be improved.

(5) Also, the upper and lower attachments 14A and 14B are composed of the same member formed with the finding surface portion 141 and the inclined surface portion 142, and these members are reversed so that the parts can be shared. Can be planned.
