Description

[Detailed Description of the Invention] The present invention relates to a retaining structure for foreign window shoji, etc., which has a hinge structure in which the connection between the shoji stile and the window frame body is rotatably supported by a profile.

Conventionally, in the case of outward-folding windows, etc., the hinge structure of aluminum profiles fitted together has the drawback that the limit for safe opening and closing is at the front and back of the opening of 45 degrees, and when the window is opened more than 60 degrees, the connection by the hinge comes undone.

Therefore, in the past, a mechanism such as an arm stopper was used as an opening angle adjustment tool, but there was a risk that the shoji would fall if the opening angle exceeded a predetermined angle due to a failure or the like.

Other than the fitting structure of the shapes, problems such as installing stainless steel hinges separately resulted in high costs and decreased workability.

The present invention provides a simple structure that eliminates the above-mentioned drawbacks in the fitting of the window frame material and the window frame material itself.

Embodiments will be described in detail below with reference to the drawings.

FIG. 1 is a longitudinal sectional side view of a window structure according to the present invention.

Number 1 is the lower stile of the shoji screen, and number 2 is the vertical stile.

Reference numeral 3 denotes a rim for fitting the glass 4 into the lower frame.

5 is a spacer for positioning the glass, and 6 is a sealing material 6' is a seal receiver.

The above is the structure of the hinge part of Gaishin (shoji).

7 is the lower frame of the window frame body for the shoji.

8 is a weather strip interposed between the window frame and the shoji, and is inserted and fixed to the lower frame.

A is a shoji side engaging part, and in FIG. 1, it is a hanging piece that hangs down from the substantially indoor end of the lower stile of the shoji in a normally closed tapered state, and its tip has an arc shape 9. There is.

10 is preferably provided as a stopper.

C denotes a protrusion, and in this embodiment, it is made of neoprene rubber and has a cross-sectional shape as shown in FIG. .

The figure shows a state in which a plurality of protrusions are fitted into a pre-opened elongated notch.

At this time, the fitting piece 11 having a triangular head shape can be easily inserted due to the presence of the recess step 12, and is fixed after being fitted and cannot be removed.

Note that the protrusion C may be made of other materials, for example, if a metal material is used, it may be fixed with screws or the like. Reference numeral 13 is a hanging piece corresponding to the engaging portion A.

B is a horizontal piece extending toward the outdoor side from the upper end of the lower frame of the window frame body, that is, the window frame side retaining part in the present invention.

The inner surface of the tip of the retaining part B is circumscribed and slidable on the tip arc 9 of the aforementioned shoji side retaining part A, and its curved surface is similarly arcuate.

In other words, when the frame is closed, the frame-side retaining part B is located within the shoji-side engaging part A and the hanging piece 13, and is held within the shoji frame by the interposition of the protrusion C to maintain a stable state.

When opening 90 degrees from the closed state, the protrusion C slides circumscribed on the frame-side engaging portion B, resulting in the state shown in FIG. 2.

FIG. 2 shows the shoji in a state when it is opened 90 degrees, and the arrow frame side engaging portion B is more firmly clamped within the shoji frame via the protrusion C.

Due to the above-described configuration and operation, the shoji will not come off and fall.

Figure 3 shows the case where the hanging piece 13 on the shoji side is missing, and the protrusion C is made of a strong protrusion with a core, for example, to maintain approximately the same strength as the lower stile hanging piece 13, and then hang down. It served as a piece.

FIG. 4 also shows a different embodiment in which the protrusions C are fitted onto the frame side, and the figure shows the state when it is sealed.

Although the above-mentioned embodiment drawings illustrate an outward-folding window shoji, the present invention can be similarly applied to an inward-folding shoji, a protruding shoji, and an inward-raising shoji in addition to an outward-folding shoji.

As explained above, by simply fitting elastic protrusions into a part of the form material, the drawbacks of the conventional method can be overcome, contributing to cost reduction and productivity improvement, and it is extremely easy to attach to shoji frames or frames. The shoji can be safely opened and closed up to 90 degrees.
