Description

[Detailed description of the invention] [Field of industrial application] The present invention is a wind stopper at the bottom of the mating stile in a sliding sash window, that is, a
This invention relates to a wind blocking device that closes the gap by interposing a wind blocking plate in the gap created between the lower part of the stile of the inner shoji and the upper surface of the lower frame of the window frame when the outer shoji is closed.

[Conventional technology]

Regarding the general configuration of this type of general wind stop device according to the conventional example, a vertical cross-sectional view and a cross-sectional view of the main part at the joining frame part are shown in FIGS. 9 and 10, respectively.
FIG. 11 shows an exploded perspective view of the main parts of the same.

In each of these figures, on the lower frame 1 constituting the window frame, there are outer rail pieces 2, A screen door rail 4 is installed at the outdoor end, and an inner rail piece 3 is installed at the elevated upper surface 1a on the indoor side.
Indoor side rising pieces 5 are respectively protruded at the ends of the room, and on these outer and inner rail pieces 2 and 3, outer and inner shoji screens 6 and 7 are respectively attached to the lower frames 8 and 9. It is supported so as to be openable and closable by door rollers 10 and 11 which are pivotally supported within both ends of the lower part.

Furthermore, when the outer shoji 6 and the inner shoji 7 are in a closed state, their respective vertical frames located at the center of the window frame, that is, the mating frames 12 and 13 overlap each other. By tightening with a crescent lock or the like, the overlapping frames 12 and 13 are attracted to each other, and the airtightness of the entire sash window is maintained by the function of the airtight members interposed in each part. It is becoming more and more like this.

However, in the conventional sliding sash window constructed in this way, as mentioned earlier, the interior side of the lower stile 9, which corresponds to the lower part of the joining stile 13 of the inner shoji 7, It is known that due to the structure of each shoji, a gap inevitably occurs between the lower edge portion 9a of the shoji and the high upper surface 1a of the lower frame 1 from which the inner rail piece 3 is protruded. Due to the existence of these gaps, outside air can enter the room from the outside, or wind can blow in, or, conversely, inside air can escape from the room to the outside, or can be blown out, making it difficult to maintain the indoor environment. Not only is this undesirable from a standpoint, but it also causes the inconvenience that rainwater that enters through the gap is easily blown by the wind and enters the room.

Therefore, conventionally, the inner rail piece 3 at the corresponding part was used as a wind blocking device to close the gap to the minimum extent that does not interfere with the opening and closing of each shoji.
A wind-blocking plate 14 is used to hold the wind-blocking plate 14 in the gap, and the wind-blocking effect is achieved by interposing this plate 14 in the gap. That is, the wind stop plate 14 is made of, for example, a synthetic resin, and is formed into a flat plate shape, in other words, a one-piece piece, with a protrusion for preventing detents, etc., and has a predetermined thickness. is fitted from the outside into a holding hole 3a formed in the corresponding portion of the inner rail piece 3 described above, and is held in close contact with the upper surface 1a of the lower frame 1, thereby forming a wind stopper. .

In addition, as shown in Utility Model Application Publication No. 56-155095,
Fix the inner and outer wind stoppers to the indoor and outdoor sides of the inner rail on the upper surface of the lower frame with screws or rivets, or install locking legs or arms on the inner and outer windstop members to lock them. There was a wind stopper at the bottom of the stile that allowed the legs and locking arms to lock into the holes provided in the upper surface of the lower frame and the inner rail.

As described above, in a window frame in which a high upper surface is provided on the indoor side of the lower frame 1 and a low upper surface is provided on the outdoor side, an airtight material mounting member for an external shoji is provided on the low upper surface, An airtight material that slides into contact with the inner side surface of the lower stile of the outer shoji is fixed to this airtight material mounting member, and the opening end surface of the mounting member is closed with a lid member.

[Problem that the invention attempts to solve]

However, in the conventional wind stop device shown in FIGS. 9 to 11 described above, the flat wind stop plate is simply inserted into the holding hole of the inner rail piece. Due to vibrations associated with opening/closing, other vibrations, or changes over time, the wind stop plate may shift, lift up, or come off, making it difficult to function properly as a wind stop. In addition, there was a problem in that wind and rainwater leaked into the room from between the windstop plate and the retaining hole wall of the inner rail piece.

In addition, the conventional wind stop device shown in Japanese Utility Model Application Publication No. 56-155095 can solve the problems of those shown in Figs. If the device is fixed to the upper surface of the frame, the number of installation steps will increase, and in order to lock the locking legs and locking arms of the internal wind stopper into the holes provided in the lower frame, the locking legs and locking arms must be installed inside the frame. By elastically deforming a part of the wind stopper member, the inner wind stopper member is pushed into the narrow gap formed between the inner rail piece of the lower frame and the indoor side rising piece, and the locking leg, locking arm and In both cases, there was a problem in that the installation workability of the internal wind blocking member was not good because the holes had to be aligned with each other.

Furthermore, in the case of using an airtight material mounting member, since the open end surface of the mounting member is closed by a separate lid member, there is a problem that the number of parts is large.

This invention solves the three problems mentioned above,
The inner and outer wind blocking members can be installed on the inner rail interior or outdoor side of the upper surface of the lower frame with ease of work, and can be positioned and fixed securely.Moreover, by using the external wind blocking members, the opening end surface of the airtight material acquisition member can be fixed as a component. It is an object of the present invention to provide a wind blocking device for the lower part of a stile in a sliding sash window that can be easily closed without increasing the number of sliding sash windows.
