Description

[Detailed description of the invention] This invention improves the inner and outer sashes of the double sash to have an insulating structure that prevents condensation and is easy to install.

As is well known, double window sashes installed in buildings in cold regions either have an inner sash A and an outer sash B installed separately, or the inner sash is integrally molded and the inner sash is attached internally to the window frame F.
The outer sash was attached externally to the window frame, but when the inner and outer sashes are attached separately, it is difficult to maintain airtightness between the inner and outer sashes, and when the inner and outer sashes are integrally molded, However, the disadvantage was that condensation easily formed on the inner sash due to heat conduction.

Therefore, this idea is to provide joint plates and joint walls that overlap each other on the facing surfaces of the inner and outer sashes, each protruding toward the other sash side, so that the inner sash can be installed in a way that can be adjusted in and out. A fitting part made of a tight material that prevents heat conduction is provided on either the joint plate or the joint wall, so that the inner and outer sashes can be connected airtightly in an insulated state.

Next, the structure of the proposed double window sash will be explained with reference to the drawings of the embodiment. A circular inner wall IB is attached to the inner wall IB of the frame IB and the inner wall 3B of the vertical frame IIIB.

A joint plate lb protrudes from the middle part of 3B at right angles to the indoor side,
The upper edge plate 2B formed on the lower frame nB of the sash B from which the sash 3b is integrally molded is extended to the tips of the joining plates 1b and 3b, while the upper edge plate 2B constituting the inner sash A that is internally attached to the window frame F is extended. The joint plate 1 of the outer sash B is attached to the main wall IA of the frame material IA, the main wall 2A of the lower frame material IIA, and the main wall 3A of the vertical frame material IIIA, respectively.
b, 3b and the joining walls 1a, 2 that overlap on the inner peripheral side of the upper edge plate 2B.
a.

3a, and in the overlapping range of the joining walls 1a, 2a, 3a, the joining plates 1b, 3b of the outer sash B, and the upper edge plate 2B,
In addition to making the inner sash A adjustable in and out, there are joining plates 1b, 3b of the outer sash B on the outer periphery of the joining walls 1a, 2a of the overlapping upper and lower frame members IA, IIA, and the joining wall 3a of the vertical frame material IA. A fitting part 6 is provided that opens toward the upper edge plate 2B, and a heat insulating tight material 5 for preventing heat conduction is attached to the fitting part 6. A fitting part 6A that opens toward the joint walls 1a, 2a, and 3a extending from the main walls IA, 2A, and 3A of the inner sash A on the inner peripheral side.
are provided, and the joint walls 1a, 2a, of the inner sash A are provided in the fitting part 6A.
Attach the tight material 5 that is in close contact with 3a, and
The main walls of the lower frame members IIA and IIB constituting B are formed to be lower in order from the indoor side to the outdoor side.

In addition, the main walls IA, 2 of each frame material IA, I[A, IIIA
A, on the back surface of 3A, there is provided a locking piece 8 that comes into contact with the window frame F on the indoor side from the tight material fitting part 6A.

Since the double window sash of the present invention has the above structure, in order to attach it to the window frame F, the outer sash B is first attached externally to the window frame F.

At that time, the connecting plate 1b provided on the inner wall IB of the upper frame 1b constituting the outer sash B, the connecting plate 3b provided on the inner wall 3B of the vertical frame I[B, and the lower frame IIB projecting toward the indoor side. The upper edge plate 2B is attached so as to overlap the indoor exposed surface f of the window frame F.

Next, in order to internally attach the inner sash A to the window frame F, use the fitting parts 6 provided in advance on the joining walls 1ay 2a, 3a of the inner sash A, or the connecting plates 1b, 3b of the outer sash B and the upper edge plate 2B. The tight material 5 is attached to the fitting part 6A provided in the inner circumferential side of the outer sash B's joining plates 1b, 3b and the upper edge plate 2B, to which the inner sash A's joining walls 1a, 2a, 3a are attached first. Insert so that they overlap, adjust the insertion and removal of inner sash A, and nail it.

Joint plates 1b, 3b and upper edge plate 2B of outer sash B attached externally to window frame F, and connecting wall 1 of inner sash A attached internally to window frame F
a, 2a, and 3a are formed to overlap beyond the adjustment range of the inner sash A, so the exposed surface f of the window frame F
is almost hidden by the inner and outer sashes A and H, and the overlapping portions of the inner and outer sashes A and B are always in close contact via the tight material 5, regardless of the adjustment of entry and exit, so that the inner and outer sashes A
, There is also little heat conduction between B.

Further, the locking piece 8 of the frame material is brought into contact with the window frame F, and air circulation on the back surface of the frame material is blocked.

Therefore, if the proposed double window sash is used, the inner sash installed inside the window frame will be attached to the inner circumferential surface of the upper edge plate of the lower frame and the joint plate that protrudes toward the indoor side from the outer sash that is attached externally to the window frame. The connecting walls extending outward from the earthen wall are formed so as to overlap, and the installation is achieved by adjusting the entry and exit of the inner sash within the overlapping range, so the exposed surface of the window frame is roughly covered by the inner and outer sashes. It can be concealed, the inner and outer sashes can be easily attached, and the finishing process of the window frame can be simplified.

Moreover, since the overlapping parts of the inner and outer sashes are joined through a tight material with high heat insulation effect, heat conduction between the inner and outer sashes is prevented without being affected by the adjustment of opening and exit, and condensation that forms on the inner sashes is significantly reduced. Not only is this possible, but even if condensation forms on the inner sash, the main walls of the bottom frame of the inner and outer sashes are gradually lowered toward the outside, so the condensed water will naturally drain outside, and the garbage that has accumulated on the inner sash will also be removed. Can be easily swept outside.

In addition, the locking pieces provided on the back side of each frame material come into contact with the window frame and prevent the flow of indoor air on the back side of the frame and the air inside the outer and inner sash frames, so there is no heat loss due to convection, etc. The double window sash has the above-mentioned features of improved heat insulation effect and simplified installation means, and has a remarkable practical effect.
