Description

[Detailed Description of the Invention] <Industrial application field> The present invention relates to a window sealing device installed in an opening of a building, and more particularly to a window sealing device effective for sound insulation in a window having a sliding sliding door. is there.

<Prior Art> As a structure of a window provided in an opening of a building, there is one having a sliding door. The sliding shoji is widely used because of its simple structure and large opening area, but its sealing property is poor. Then, as a device for improving the sealing property of the sliding shoji, for example, there is a device described in Japanese Utility Model Publication No. 51-19817.
This invention covers the space formed by the vertical frame and lower frame of the window and the vertical frame and lower frame of the shoji with a strip cover when the shoji is closed, and receives the shoji when the shoji is opened. The above-mentioned strip-shaped cover is housed in a tool so that it can be wound up.

<Problems to be solved by the invention> However, since the above-described sealing device having the band-shaped cover covers only the lower part of the window, not only is it not possible to obtain sufficient sealing performance, but also the front and rear edges of the band-shaped cover. Since the shoji is opened and closed while being in contact with the lower frame of the shoji, the opening and closing operation of the shoji is heavy,
The band-shaped cover is worn.

On the other hand, in recent years, due to an increase in external noise, a window excellent in sound insulation is desired in a house or office, and a window having high sound insulation is also required in a factory or the like to prevent noise from leaking to the outside. However, double glazing and dead-end windows with good sound insulation are complicated to construct and expensive to construct. In addition, the existing windows must be removed to install sound-insulating windows, which makes them unsuitable for expansion and renovation.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and a plurality of sealing pieces having appropriate lengths are connected by a hinge so as to be bendable in a longitudinal direction in a bellows shape to form a vertical frame of a window. And a vertical frame of the shoji, and a sealing member having a plurality of guide rollers attached in the longitudinal direction in the vicinity of the connecting portion, and a horizontal frame of the window, which is attached to face the lateral frame of the shoji. Rail-like holding member that guides the guide roller of the above in the direction of the horizontal frame of the window, and the sliding plate attached to this holding member is guided by the guide rail in the direction orthogonal to the horizontal frame of the shoji, and the sliding plate is guided. When the cam hole of the connecting rod engages with the pin and the sliding plate moves in the direction parallel to the window, the pressing mechanism that brings the seal member into and out of contact with the lateral frame of the shoji through the holding member, and the shoji The attached cam moves the sliding plate via the link mechanism. The cam part operates the link mechanism at the same time as the closing of the shoji, so that the sliding plate moves and the seal member abuts against the horizontal frame of the shoji, and the cam part links at the same time as the shoji opens. By operating the mechanism, the sliding plate moves to separate the seal member from the shoji, and the seal member starts to bend.

<Action> For example, by a pressing mechanism that cooperates with opening and closing of the shoji, the seal member can be pressed against the lateral frame of the outer shoji while the shoji is closed, and the seal member can be retracted when the inner shoji is opened. When opening the internal shoji, the apparent length of the seal member is shortened so as not to obstruct the opening of the internal shoji.

<Embodiment> Hereinafter, the present invention will be described with reference to an embodiment of the drawings.
