Description

[Detailed description of the invention] This invention relates to a double sash made of aluminum that doubles indoor and outdoor areas and has an inner shoji and an outer shoji.

This type of sash is mainly used to enhance the heating effect in cold regions, but aluminum has good thermal conductivity, and the sash frame is made of a single extruded shape like conventional ones. However, in the winter, the entire frame was cooled by the cold air outside, and the temperature difference between indoors and outdoors caused condensation to form on the frame, causing leakage and corrosion of the window sill.

This invention was devised to solve the above-mentioned drawbacks. In particular, the lower frame of the sash frame is composed of an inner lower frame for receiving the inner shoji, an outer lower frame for receiving the outer shoji, and an auxiliary member, and the inner The lower frame and the auxiliary member are connected via a backing on the window sill, and the external lower frame is screwed to the auxiliary member to cut off heat conduction, and the distance between the inner and outer lower frames can be adjusted. There is.

Hereinafter, embodiments of this invention will be described based on the drawings.

In the figure, 1 is the lower frame of the sash, 2 is the formwork, and the lower frame 1 is
an internal lower frame 1A for receiving sliding type inner shoji 3, 4;
It is composed of an external lower frame 1B that receives an external shoji (not shown in the drawing), and is placed continuously on a window sill 5.

The internal lower frame IA has several leg pieces 6 suspended from the upper wall 7, which is the main body, and guide walls 10, 11, 12 of internal shoji 3, 4 at both ends of the indoor and outdoor sides and in the center. A running groove 9 for the door roller 8 is formed so as to protrude upward, and between each guide wall of the upper surface wall 7.

A pocket 13 that opens toward the outdoors is provided along the entire length of the guide wall 12 at the outdoor end of the inner lower frame 1A. The base of the heat insulating backing 14 is fitted into the pocket 13, and the tip of the backing 14 is supported on the support piece 15.

Next, the external lower frame 1B has a water return wall 17 standing upright on the indoor side of the main part provided with rails for guiding the external shoji, and projects toward the indoor side over the entire length of the upper end of the water return wall 17. The upper piece 18 is connected to the inner lower frame IA through an auxiliary member 21, and the auxiliary member 21 has a substantially H-shaped cross section, and the side wall 22 of the member 21 The upper piece 18 is integrally fastened to the side wall 22 by screwing a screw 19 passed through a through hole 20 made in the upper piece 18, and the entire length of the upper part of the indoor side of the auxiliary member 21 is contact piece 23
The contact piece 23 is provided so as to come into pressure contact with the upper surface of the backing 14 when the auxiliary member 21 is placed on the window sill 5.

The formwork 2 is also divided into an internal formwork 2A and an external formwork 2B, which are connected via a backing 24 like the lower frame 1.

In addition, a guide wall 1 is installed at the lower end of both the indoor and outdoor surfaces of the inner shoji 3 and 4.
A backing 16 in contact with 0, 11, 12 is fixed, and the backing 16 provides heat insulation between the internal lower frame 1A and the shoji 3, 4.

This invention has the above structure, and when fitting the sash frame onto the window sill 5, after placing and fixing the internal lower frame 1A on the window sill 5, the auxiliary member 21 is placed on the outdoor side of the window sill 5. At the same time as it is placed, the contact piece 23 is pressed downward and pressed against the backing 14 protruding from the inner lower frame 1A by applying a pressing force toward the indoor side, and then the outer lower frame 1B is fixed. The upper piece 18 is placed on the auxiliary member 21 and fixed with screws after adjusting the degree of overlapping thereof, and the external lower frame 1B is attached to the outside of the window sill like a sash.

As described above, the lower frame of the double sash according to this invention is divided into the inner and outer parts, and the outer lower frame is connected to the inner lower frame via the auxiliary member, and the contact piece protruding from the auxiliary member is attached to the inner lower frame. The receiver is pressed into contact with the backing provided on one side, and the external lower frame can be adjusted to overlap with the auxiliary member, making it easy to adjust the distance between the inner and outer lower frames, and to accommodate differences in the width of the window sill. It can also be fitted in a suitable manner.

Further, a part of the backing is sandwiched between the contact piece of the auxiliary member and the inner lower frame, so that the backing is securely connected to the backing in a state of being blocked.
