Description

[Detailed description of the invention] This invention relates to single-sliding windows made of aluminum sash, etc., and in particular, within the window frame fitted with inner and outer shoji, the inner shoji can move left and right, and when the window is closed, the outer shoji The present invention relates to an improved single-sliding window configured to be retractable in a straight line on the same plane as an inner shoji.

Conventionally, for example, in sliding windows, the outdoor surfaces of the outer and inner shoji are at different levels, which makes the appearance unsightly and difficult to maintain an airtight seal between the inside and outside of the window.

Therefore, in order to improve the above problems, the inner and outer shoji can be slid left and right and opened and closed freely, and the outer shoji can be drawn in a straight line on the same plane as the inner shoji with the window closed. A sliding window has been proposed that has the following configuration to improve its appearance and airtightness.

However, in the sliding window with the above configuration, a rail part is provided at the top of the window frame having a substantially U-shaped cross section, and the inner shoji and the outer shoji are hung from the rail part so as to be movable from side to side. This is a top-hung window that is equipped with a retractable guide, a retractable arm, etc., and configured so that the outer shoji is on the same surface as the inner shoji when the window is closed.

Therefore, in top-hung windows, hanging metal fittings and pulleys are attached to the upper part of the window frame for both inner and outer shoji, and a retracting device that pulls in or extends the guide plate is attached to the lower part of the outer shoji. In window frames attached to the outer walls of buildings,
The structure required shoji screens to be built from the outside.

For this reason, if one of the shojis needs to be removed due to broken window glass or other reasons, it cannot be removed indoors, so the work must be done from the outside.
1338) was accompanied by considerable danger.

This idea was made based on the above-mentioned circumstances, and while maintaining the effect of conventional windows, it allows at least the inner shoji of the inner and outer shoji attached to the window frame to be easily accessible from the indoor side when necessary. To provide an improved single-sliding window that is configured to be detachable.

Hereinafter, embodiments of this invention will be described in detail with reference to the accompanying drawings.

1 and 2 are a cross-sectional view and a longitudinal sectional view of a single-sliding window according to this invention, and the lower side of FIG. 1 and the left side of FIG. 2 are the outdoor sides.

The window frame 1 consists of vertical frames 1a and la on both sides, a horizontal upper frame 1b vertically above the frames 1a, and a lower frame 1c at the bottom.

A concave groove is formed on the indoor side end surface around the window frame 1, into which a tight member 2 for airtightness is fitted, and when the inner shoji 3 and the outer shoji 4 are fully closed, the indoor side is airtight. Retain your sexuality.

A guide protrusion 1d for pressing the inner shoji 3 against the indoor tight member 2 is provided on the inner shoji 3 side of the vertical frame 1a,
A hanging wall 1e for guiding a roller 5 attached to the upper part of the inner shoji 3 and an inner wall 11 are integrally provided from the upper frame 1b.

A downward guide groove 11 is provided between the hanging wall 1e and the inner wall 11.
is formed.

The above-mentioned inner shoji 3 is a vertical stile 3at3a framed in an almost rectangular shape,
It consists of an upper stile 3b and a lower stile 3c, and two glass plates 7 are fitted through a shield packing 6.

On one side of the vertical stile 3a of the inner shoji 3 is the vertical frame 1 of the window frame 1.
A guide roller 8 is attached that presses the inner sash 3 against the tight member 2 by coming into contact with the guide protrusion 1d provided at the vertical stile 3.
On the other side located at the center of the window a, an outer shoji 4 is formed into a shape that can be easily drawn in.

In addition, the lower stile 3c of the inner sash 3 has an inner lower piece 3f formed shorter than the outer lower stile 3e, extending over the entire length of the lower frame 1c of the window frame 1 mentioned above. A door roller 9 is mounted that runs left and right on the running rail 1f.

In addition, drain holes 1g are bored at appropriate locations in the traveling rail 1f.

The lower frame 1c has the upward traveling rail 1f and a rising wall 1h higher than this.

Also, the outer shoji 4, like the inner shoji 3, consists of vertical frames 4a, 4a, an upper stile 4b, and a lower stile 4c, which are framed in a rectangular shape.
Two glass plates 7 are fitted with a shield gasket 6 interposed therebetween.

On the side of the vertical stile 4a of the outer shoji 4 located at the center of the window,
A tight member 2a is placed at a position where it contacts the vertical stile 3a of the inner shoji 3.
is fixed, and when the outer shoji 4 is in a fully closed state, together with the tight member 2 fixed around the fixed window frame 1, it maintains airtightness between indoor and outdoor spaces.

Further, an arm 10 is pivotally supported on the upper surface of the upper frame 4b of the outer shoji 4, and this arm 10 is attached between the hanging wall 1e provided on the upper frame 1b of the window frame 1 and the outer hanging wall. The rotating shaft 11 is supported by

The arms 10 are provided at two locations above the outer shoji 4.

A support shaft 12 extends from the lower stile 4c of the outer shoji 4, and is rotatable on an arm 15 that is pivoted via a rotation shaft 14 to a pedestal 13 fixed to the lower frame 1c of the window frame 1. is supported by

The arm 15 has an arm length that allows the outer shoji 4 to be pulled in or pushed out, and the inner shoji 3 travel rail 1
Since it is installed below f, it does not interfere with the left and right movement of the inner shoji 3.

The inner shoji 3 is longer than the vertical length of the opening of the window frame 1, but the distance A between the lower surface of the guide groove 1j of the upper frame 1b and the roller 5, and the lower side of the lower piece 3e of the lower stile 3c. The distance B between the end face and the upper end face of the rising wall 1h of the lower frame 1c is A>B
Therefore, by lifting the inner shoji 3 to the opening of the lower frame 1c of the window frame 1 and tilting it slightly, it is possible to remove it from the indoor side, and there is no need to remove any parts. be.

In addition, 3d is a notch groove that should serve as a relief for the hanging wall 1e of the upper frame 1b.

According to the above-mentioned device, since the interior of the lower frame 1c is open to the outside of the room, the pressure between the outside and the interior of the lower frame 1c is equal, and rainwater that has entered the lower frame 1c remains. Without a problem,
Since the water is immediately drained through the water drain hole 1g, etc., it is possible to prevent rain and ice from entering the room.

Note that the operation of pulling in or pushing out the outer shoji 4 is performed by an operation lever (not shown), and the operation lever is provided with a self-locking mechanism, etc., so that the outer shoji 4 and the window frame 1 can be easily connected. It is possible to ensure the airtightness of the door and to lock the door.

As explained in detail above, according to the improved single sliding window of this invention, complete airtightness is maintained when the outer shoji is drawn into the same plane as the inner shoji, and the inner shoji can not be moved left or right. The door is completely locked.

Furthermore, by unlocking the operating lever and pushing the outer shoji outward, ventilation can be made indoors and outdoors, and the inner shoji can be moved in this state.

All operations of the above-mentioned outer shoji can be performed reliably by simply operating the operating lever.

Furthermore, if the interior shoji needs to be removed due to damage to the glass panes or for other reasons, it can be easily removed by simply lifting the shoji slightly upwards from the indoor side.

Therefore, the user is freed from the risk of working from outside the room as in the prior art.

Furthermore, even if the inner shoji were to derail from the traveling rail while running, there is no fear of it falling off because the shoji is located on the outside of the room, which provides practical effects.
