DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fitting that pivots and opens and closes, such as a hinged door (window) or a sliding door (window) having a shoji having a frame made of a heat-insulated member. More specifically, the present invention relates to a structure for correcting warpage of a frame caused by sunshine.

[0002]

2. Description of the Related Art As shown in a schematic vertical sectional view of FIG. 4, in a fitting such as an entrance door, a self-service door or a hinged door, heat is prevented from being transmitted in the indoor and outdoor directions through a fitting frame 20 and a shoji 21. In order to increase the heating efficiency and the cooling efficiency, the frames 20 and the frames 21 are provided with heat-insulated profiles (outside members 20a, 21a and interior members 20b made of extruded members made of aluminum alloy).
21b and a heat insulating material 2 made of synthetic resin or ceramic.
Conventionally, it is configured by a shape member joined by Oc and 21c).

[0003]

In the case of a fitting provided with a frame made of such a heat-insulated profile, a sliding door outdoor member 2 pivotally attached to a frame 20 by upper and lower hinges 22 so as to be openable and closable.
When sunlight is radiated to 1a, the heat conduction of the heat insulating material 21c is poor, so that the heat is blocked by the heat insulating material 21c and is not conducted to the indoor side member 21b. 21b, the temperature difference from the outside member 2
1a expands and the indoor side member 21b does not expand, so that the shoji warps as shown by a two-dot chain line, thereby creating a gap between the frame 21 and the frame 20, impairing airtightness,
As a result, there is a problem that heat insulation is impaired. The occurrence of such a warp does not cause much problem on the counter-attaching side of the shoji with the handle, since the warp is corrected by the engagement of the handle with the frame-side correcting member. Is particularly problematic at the center of the Note that the horizontal stiles above and below the shoji are generally less than half the length of the vertical stiles, and are short.

[0004] The pivot side frame 21 with such a hinge 22 is provided.
In order to solve the problem of warpage, it is conceivable to prevent the warpage by providing a hinge 22 also at the center in the vertical direction of the frame 21 on the pivot side, but the hinge 22 is an expensive component. Therefore, increasing the number of hinges 22 causes an increase in price.

SUMMARY OF THE INVENTION In view of the above problems, the present invention prevents a warp of a frame on a pivot side of a sliding door without incurring an increase in price in a pivoting opening / closing fitting using a heat-insulated profile for the sliding door frame. It is intended to provide a product having improved airtightness and heat insulation.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a shoji frame in which an outdoor member and an indoor member are connected by a heat insulating material, and the frame is formed in a longitudinal direction. At two places, the hinge is pivotally attached to the frame, and in the longitudinal middle part of the pivot side frame of the shoji and the longitudinal middle part of the frame,
Fixtures provided with correction means for correcting warpage by pressing each other by thermal expansion of the outdoor member of the shoji. .

[0007]

According to the present invention, when the shoji is closed, the outdoor member of the shoji is thermally expanded due to sunshine, and the longitudinal center portion of the pivot-side frame is projected outward by the hinge of the shoji. When this occurs, the straightening means attached to the frame on the pivot side of the sliding door is pressed against the straightening means attached to the frame to prevent the warp of the frame.

Further, when the shoji is opened, the outdoor member of the shoji is thermally expanded due to sunshine, and a warp is generated by the hinge of the shoji such that the central portion in the longitudinal direction of the pivoting side frame projects in the outdoor direction. Then, the straightening means provided on the frame on the side of the sliding door is attracted to the straightening means attached to the frame to prevent the warp of the frame.
