Direction, and the airtight material arranged inside the request portion presses the flange so that the door gap is airtight.

Looking at another feature of the present invention, since the roller and the roller active part are arranged so that the pair of chassis moves laterally toward each other in its closed position, it ensures complete airtight at the portion where the two chassis overlap or join.

In short, the present invention, when closing the sash, the request portion formed along the top and bottom of the sash of the sash that is in contact with one of the sash of the sliding window frame: the inside of the above-described request portion rotates at predetermined intervals Multiple vertical rollers, possibly installed: protruding inward from the sliding window frame, so that when the chassis is placed at the closing point, a number of flanges are pushed into the above-mentioned requirements: the roller is activated by activating the roller when the chassis is moved to the closing point. A plurality of roller active parts formed on the flange so as to move in the transverse direction with respect to the sliding window frame, and a plurality of airtight members arranged in the above-mentioned request part to press the above-mentioned flange to induce the above-mentioned sash movement at the closing point. It is installed in the frame, the underframe, the sliding window frame and the sliding window frame which are characterized by To provide a double sash window frame consisting of utmakyi and mitmakyi sash and a pair of horizontally movable chassis, the chassis as a fleet.

Now, the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show a double sash window frame according to the present invention, which comprises a conventional sliding window frame 10 and a pair of sash 11 acting horizontally within the window frame.

The window frame 10 fixed to the window frame insertion opening of the building is composed of an upper frame 12, a base frame 13, and a sun frame 14.

Each sash 11 is made up of the top sash 15, the bottom sash 16, and the sash sash 17, and the sash of the part joined to each other is not shown in FIG. Although not shown in FIGS. 1 and 2, it is to be understood that each sash 11 has a glass panel or other suitable material in its constituent members 15, 16 and 17. The top and bottom sashes 15 and 16 of the sash 11 and one of the sash members 17 which abut the one of the frame 14 when the sash is closed are the sash members 15, 16 and 17. It is integrated with a pair of edges 18 which form a request portion extending through the entire length of the wire.

Supported on one inner surface of the opposite rim 18 of the sash members 15, 16 and 17 is a hermetic material 19 of a non-metallic material, which is the overall length of the rim 18 There are one or more protrusions extending laterally and extending laterally. At least one, preferably two or three, spaced supports 20 are supported on the inner surface of another rim 18 of each sash member. Each of these supports 20 firmly supports the vertical shaft 21 which supports the roller 22 so that it can rotate.

The flange 23 arranged in the same plane as the sash 11 protrudes inward from the sliding window frame 10 and is partially provided as a request portion between the opposing edges 18 of the sash members 15, 16, and 17. Is inserted. The roller active portions 24, 24a, and 24b, which have the same number as the rollers 22, are supported by the flanges 23 to abut on the rollers. The relative position of the roller 22 and the roller active parts 24 (24a) and 24b allows the roller to act on the roller active part when the sash moves to the closing point in the sliding window frame 10.

And all roller actives can be made from plastic molds.

Each roller active part 24 supported by the flange 23 protruding from the frame 14 of the window frame 10 is gradually reduced toward both sides of the sash 11 of the sash 11 as shown in FIG. It has a b-shaped cross section with a branch and is attached to the window frame by way of FIG. Each roller active part 24 supported by the flange 23 protruding from the upper frame 12 of the window frame also has a b-shaped cross section with both ends of the branch as shown in FIG. 4, and is provided by the window frame by screws 25a. Is attached to. Each roller active part 24b supported by the flange 23 protruding from the underframe 13 of the window frame has a flat cross section with two inclined sides as shown in FIG. In a similar manner it is attached to each flange.

In the double sash window as described in FIGS. 1-5, the roller 22 is activated on the roller active portions 24, 24a and 24b as the sash 11 moves away from each other and closes to its closing point. . Since the sash 11 is moved to the right side of FIG. 1 and to the side of the outer window frame 10 in the lower direction of FIG. 2 by such an active force, the airtight member 19 of each sash is pressed against the flange 23. The space between the window frame and the sash is completely sealed.

In the embodiment of the present invention, the chassis 11 is horizontally moved to one side, but as described below, the chassis is moved in the opposite direction.

6 and 7 are still another embodiment of the present invention for explaining the airtightness of the overlapping portion of the chassis in the double chassis window frame of the same structure shown in FIG. The second embodiment of the present invention will be described only with other features than the first embodiment, but other features are substantially the same.

As shown in FIG. 6, at least one roller active part 24b is attached to the inner surface of each flange 23 projecting inwardly from the base 13 of the window frame 10, and the roller active part 24b is sashed. It is located near the overlapping part or overlapping part of (11). The roller 22 is relatively supported on the inner surface of the inner rim 18 extending downward from the bottom 16 of the sash 11 so as to abut against the roller active portion 24b to rotate.

As in the first embodiment, these rollers 22 are located on the rim 18, so that the rollers act on the roller active portion 24b when the sash is placed at its closing point.

As shown in the figure, two airtight members 26, which are the same as the airtight member of the first embodiment, are fixed on the frame 13 along the middle of the transverse member. The airtight material 26 extends in the opposite direction with respect to the rim 18 supporting the roller 22.

Referring to FIG. 7, a pair of L-type flanges 27 interlocked with each other are formed along the overlapping portion of the sash 11 on the opposing surface of the leading edge 17a of the sash 11. One of these fleece 17a supports the same airtight material 28 as the airtight material 19 of 1st Example, and extends longitudinally through the full length of the fleece 17a. These airtight materials 28 can press the flange 27 of the other selection 17a by closing a window as mentioned below.

It can be seen that the top 12 of the sliding window frame 10 and the top 15 of the sash 11 are hermetically sealed as shown in FIG.

In the same manner as shown in FIG. 2, except that the frame 14 of the sliding window frame 10 and the opposite stem 17 of the sash 11 are also moved to the inside of the window frame 10 at the closed position of the sash. You can see that it is confidential.

Looking at the second embodiment of the present invention shown in Figure 6 and 7 as follows. The roller 22 near the overlapping portion or the overlapping portion of the sash 11 acts as a closed position on the roller active part 24b by the movement of the sash, and the roller 22 installed on the sash 17 of the sash has a sliding window frame 10. It acts on the roller active part 24 on the frame 14 of the (). Therefore, the sash 11 is horizontally moved horizontally with respect to the window frame 10, and as a result, the airtight material 26 is pressed by the edge 18 facing the top and bottom portions 15 and 16 of the sash. Receive. The hermetic material 28 extending along the sash 17a of one sash is also pressed by the L-shaped flange 27 on the sash 17a of another sash to seal the overlap of the two sashes. Since the airtight member arranged along the front sash 17 is simultaneously pressed by the flange which protrudes inwardly from the frame 14 of the sliding window frame 10, the airtight of the completed window frame assembly becomes easy.

It is believed that the features of the present invention can be accurately understood from the drawings and the description above. As an example, as shown in the drawings, instead of installing a roller on the sash edge and a roller active portion on the flange of the window frame, it is also possible to install the roller on the flange and the roller active portion on the edge. It is in range.
