Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash in which a metal indoor frame and an outdoor frame are connected to each other through an insulator made of a heat insulating material, and heat conduction between the two frames is prevented by the interposed body. Related to a frame for fittings such as doors and sliding doors.

[0002]

2. Description of the Related Art A metal sliding window device having a heat insulating sash as a sash is known from Japanese Utility Model Publication No. 60-68175 and Japanese Utility Model Publication No. 4-25913.
Japanese Utility Model Laid-Open No. Sho 60-68175 is characterized by a structure in which the surface of an indoor frame composed of upper, lower, left and right frame members is thinly coated with resin. As a preventive measure, a structure is shown in which the surface of each frame member other than the surface of the lower frame member of the indoor frame is covered with a thick wooden decorative board.

[0003]

By the way, in the sliding window devices disclosed in the above-mentioned publications, the lower horizontal frame is most easily visually recognized, but the interposer provided in the horizontal frame is exposed. There is. Therefore, there is a problem that the appearance is not good.

Therefore, the present inventor has found that
It has been proposed to provide a cover on the interior frame as shown in the conventional example of Japanese Patent No. 3 to improve the appearance. Above all, the cover is a low heat conductive material such as synthetic resin or synthetic rubber which is easily available in terms of resources. As a result of trial manufacture, it was found that there is a problem that needs further improvement.

More specifically, the synthetic resin cover is attached so as to cover at least the surface of the upper, lower, left, and right sides of the interior frame that faces the sash opening of the lower horizontal frame member. Is larger than the coefficient of thermal expansion of the metallic material forming the. Moreover, the temperature difference when using the heat insulating sash is large. For example, the temperature of the lower horizontal frame material of the outdoor frame is about 80 ° C. under the direct sunlight around the daytime in the Tokyo area in the summer (about the left and right sides and the upper side of the outdoor frame under the same use condition). The temperature of the frame material is about 50 ° C, and the temperature of each frame material on the top, bottom, left and right of the indoor frame is about 25 ° C. Is about −5 ° C. to 0 ° C., and the temperature of each frame member on the upper, lower, left and right sides of the indoor frame is 15 ° C. to 20 ° C. As can be seen from this example, the temperature difference of the lower horizontal frame member is particularly large.

Therefore, even when the length of the cover is adjusted to the same size as the length of the portion facing the sash opening of each frame member at the time of manufacturing, the cover is based on the temperature difference between the time of manufacturing and the installation of the window device in the building. It may be difficult to screw the cover to the frame material of the indoor frame at multiple points due to the expansion and contraction of the cover, and if the cover is stretched, part of the cover will rise if it is stretched. Damage the appearance,
Further, there is a problem in that the cover is expanded and contracted during use, so that the load is concentrated on the screwed portion and the cover is easily damaged at an early stage.

The object of the present invention is not only to improve the appearance, but also to make it possible to easily attach the cover provided for it regardless of its expansion and contraction, and to prevent early damage to this cover. To get the quota.

[0008]

In order to achieve the above-mentioned object, the fitting frame of the present invention is formed by framing upper and lower horizontal frame members made of metal and left and right vertical frame members made of metal. A lower body including an indoor frame and an outdoor frame that are connected via upper, lower, left, and right interposers made of a heat insulating material, the lower horizontal frame members of the indoor frame and the outdoor frame, and a lower interposer that connects them. The cover is provided on the surface of the side lateral frame so as to cover at least the interposer of the lower lateral frame, and the cover is formed of a low thermal conductive material having a thermal expansion coefficient larger than that of the lower lateral frame member. ,
At least one end of both ends in the longitudinal direction of the cover is a free end displaceable in the longitudinal direction of the lower lateral frame,
A part of the cover is fixed to the lower horizontal frame or a vertical frame connected to the lower horizontal frame.

[0009]

In the construction of the fitting frame, the cover for covering the lower horizontal frame hides the intermediate body of the lower horizontal frame from the inside of the sash opening, and prevents the intermediate body of the lower horizontal frame from being visually recognized. Since this cover is a low heat conductive material, it does not serve as a heat conduction path between the indoor frame and the outdoor frame.

Since the cover is partially fixed and at least one end is a free end, the position of the free end is displaced in the longitudinal direction according to the temperature change. As a result, even if the cover extends to the maximum extent, the dimension thereof is longer than the length of the portion of the lower lateral frame facing the fitting frame opening, and there is no difficulty in attaching the cover to the lower lateral frame. At the same time, unlike the case where at least both ends of the cover are fixed, by fixing only a part of the cover, the cover can be contracted after assembling the fitting frame, and moreover, the expansion and contraction of the cover as described above can be prevented. At this time, a load is not significantly applied to the fixed portion of the cover.

In the structure of the above-described embodiment, the covers 7, 8 and 10 attached to the upper and lower horizontal frames 25 and 26 and the right vertical frame 28 of the heat insulating sash have the interposers 3 and 4 and 6 of the sash opening, respectively. It is hidden from the inside. Therefore, the right side portions of the upper and lower covers 7 and 8 prevent the outdoor portion of the outdoor side portion of the right half of the upper and lower horizontal frame members 17 and 18 of the indoor frame 1 facing the indoor shoji 71 when the window is closed. In addition, the right side cover 10 allows the right side vertical frame member 1 of the indoor frame 1 to be
The outdoor exposure of the outdoor portion of 4 is prevented. The left half of the upper and lower horizontal frame members 17, 18 of the indoor frame 1 and the indoor frame 1
The left vertical frame member 13 is not exposed to the outside by the outdoor shoji 72.

In this way, the frame members 11 to 1 of the interior frame 1
Since each of No. 4 is prevented from directly contacting with the outside air, the inside frame 1 and the outside frame 2 are insulated by the interposers 3 to 6, and the inside frame 1 is cooled by the outside air. Can be effectively prevented. Therefore, the occurrence of dew condensation on the indoor frame 1 can be reduced. Of course, since each of the covers 7 to 10 is made of a material having a low heat conductivity, it does not serve as a heat conduction path between the indoor frame 1 and the outdoor frame 2. Moreover, the covers 7 to 1 as described above
Since the visibility of the interposers 3 to 6 is hindered by 0, the appearance can be improved.

Further, each of the covers 7 to 10 having a thermal expansion coefficient larger than that of each metal frame material of the indoor frame 1 and the outdoor frame 2,
Shorter than the length of the upper and lower horizontal frames 25, 26 or the left and right vertical frames 27, 28 to which they are attached facing the sash opening,
A free end portion 7a in which at least one end portion can move freely by fixing only a part of the longitudinal direction end portion or the central portion.
It is 1, 7b1, 8a1, 8b1, 9a, 10a. Therefore, the temperature at the time of installation of the window is different compared to the temperature condition at the time of manufacturing, and the positions of the free end portions 7a1, 7b1, 8a1, 8b1, 9a, 10a of the covers 7-10 are longer depending on the temperature difference. Even if it is displaced in the direction, the expansion and contraction can be absorbed.

That is, in the lower cover 8, FIG.
Due to the gaps A to C shown in FIG. 1, the first and second cover bodies 8a and 8b having one end fixed within these ranges are provided.
Are allowed to extend and contract in the axial direction on the side of their free ends 8a1 and 8b1. In the upper cover 9, the gaps D and E allow the first and second cover bodies 7a and 7b whose one ends are fixed to axially extend and contract on the free end portions 7a1 and 7b1 side thereof. forgiven. Similarly, since there is a gap H in the covers 9 and 10 on both the left and right sides, the covers 9 and 10 whose lower end portions are fixed within these ranges expand and contract in the axial direction on the free end portions 9a and 10a side. Allowed to do.

Therefore, in assembling the heat insulating sash, the dimensions of the covers 7 to 10 become longer than the length of the upper and lower horizontal frames 25, 26 or the left and right vertical frames 27, 28 facing the sash opening, and the covers 7 to 10 are attached. There is no difficulty in. In addition, unlike the case where at least both ends of the cover are fixed, only a part of the covers 7 to 10 is fixed, so that the cover 7 to 10 are assembled after the heat insulating sash is assembled.
Since the expansion and contraction of the cover 10 is also allowed, the loads on the covers 7 to 10 themselves and their fixing points are less likely to act, and the durability can be improved and the cover 7 can be improved.
No part of -10 will rise.

Although the covers 7 to 10 expand and contract as described above, the free end portions 7a1 and 7a of the upper and lower covers 7 and 8 are formed.
b1, 8a1 and 8b1 are covered with the joining frame portion, and the upper and lower end portions 9a and 10a of the left and right covers 9 and 10 are the portions that do not affect the air / watertightness of the window, so that the expansion and contraction are concerned. Without damaging the air and water tightness of the windows. Moreover, the free ends 7a1, 7b1, 8a1 of the upper and lower covers 7, 8
8b1 is covered by the sashing frame. Therefore, regardless of the expansion and contraction of the left and right covers 9 and 10, the upper and lower end portions are covered with the door stop pieces 55, 56, 62 and 63,
Free ends 7a1, 7b1, 8a1, 8b1, of each cover 7-10,
9a, 10a are not visually recognized, and the appearance is good, and the free end portions 7a1, 7b1, 8a1, 8b1, 9a, 10 are formed.
No special parts are needed to cover up a.

Further, also in the frame covers 93 and 100 attached to the fitting frames of the shoji screens 71 and 72, it is possible to eliminate the visual recognition of the interposers 73 and 83, and at the same time, the wind stop pieces 98, 99, 101 and 102. Since the end portions of the frame covers 93 and 100 are not visually recognized by utilizing, the appearance of the window can be improved. Moreover, the indoor frame cover 9
3 has free ends 93a and 93b at both ends thereof, and the outdoor frame cover 100 has a free end 100a at its upper end so that the difference in thermal expansion can be absorbed by the displacement in the length direction. Therefore, the frame covers 93 and 100 are attached to the shoji screen 7.
It is possible to reduce the load on the frame covers 93 and 100 and their fixing portions due to expansion and contraction, while not impairing the assemblability of the components 1 and 72.

The present invention is not limited to the above embodiment. For example, the structure for absorbing expansion and contraction in the central portion in the length direction of the lower cover, which is shown in the one embodiment, may be applied to the expansion and contraction structure of the upper and left and right covers, and also the frame cover. The structure for absorbing the expansion and contraction of the left and right covers at one end in the length direction may be applied to the expansion and contraction structure of the upper and lower covers and the frame cover. Further, each cover may be formed of synthetic or natural rubber, and the fixing means for fixing a part of these covers to the upper, lower, left, and right frames is not limited to screws. Further, the upper and lower covers for covering the interposition body of the horizontal frame are not limited to the horizontal frame, and may be fixed to a vertical frame connected to the horizontal frame, and the left and right covers for covering the interposition body of the vertical frame are not limited to the vertical frame. Instead, it may be fixed to a horizontal frame connected to this vertical frame.

[0062]

As described above in detail, according to the fitting frame of the present invention, at least the interposer of the lower horizontal frame is covered with the cover from the inside of the opening of the fitting frame. Not only can the body not be seen but the appearance can be improved, but the cover
By fixing only a part of the cover, the cover can be easily attached regardless of the difference in the coefficient of thermal expansion between the indoor frame and the cover, and the expansion and contraction of this cover causes a load on the fixed part of the cover. There is very little effect, and therefore, it is possible to prevent premature damage to the cover.
