Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connecting device for connecting an outer frame and an inner frame in a double sash.

[Conventional technology]

Conventionally, double sash has been used in cold regions and in noise-producing areas such as around airports to achieve both thermal insulation and soundproofing effects, and to achieve both of these effects.
When using ready-made products for one or both of the outer frame and inner frame of a double sash, attach the mounting part that forms the inner peripheral surface of the outer frame and the mounting part of the inner frame that is perpendicular to this mounting part. A device that is connected and fixed using metal fittings is known from Japanese Utility Model Application Publication No. 55-143380.

As shown in FIG. 5, this device for connecting the outer frame and inner frame of this double sash is such that the outer side 20 of the mounting bracket 18, which is made of a plate material bent into a substantially square cross section, is attached to the outer frame 1.
The plate surface is brought parallel to and close to the mounting part 13 forming the inner circumferential indoor end of 0, and is fixed with a screw screwed in the thickness direction perpendicular to the plate surface, and is perpendicular to the outer side part 20. The inner side portion 22 is brought into close contact with the mounting portion 17 provided at the outdoor end of the inner frame 11 perpendicularly to the mounting portion 13 so that the plate surfaces are parallel to each other, and the inner side portion 22 is screwed in a direction perpendicular to the plate surface. It was fixed with a screw.

[Problems to be Solved by the Invention] However, the connection device for the outer frame and the inner frame in the conventional double sash described above has a mounting surface 13, 17 of the outer and inner frames 10, 11 on the outside of the mounting bracket 18, Since the inner sides 20 and 22 are parallel and closely spaced, and the thickness of these sides 20 and 22 is thin, when a large load such as an external force is applied to the joint between the outer and inner frames 10 and 11, The strength of this connection is low, and the mounting bracket 18 may not be able to withstand the load and may deform. Also, since the screws 19 and 21 are screwed together in the thickness direction of the mounting bracket 18, The axial dimension is short, and the mounting surfaces 13 and 17 and the outer and inner sides 2
There was a problem that the tightening with 0 and 22 tends to be insufficient.
