Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a sliding sash drawing device that is used to maintain airtightness between a shoji and a sash frame in a sliding sash.

<Prior art> In general, a sliding sash has a pulling function and a drawing function in order to maintain airtightness. The drawing function is to bring the mating parts of the inner and outer shoji into close contact with each other, and also to bring both shoji into close contact with the inner periphery of the sash frame via a tight material. The method is to press the sash to the vertical frame. The pull function and draw function have conventionally been performed by rotating a locking handle or a crescent.
In particular, for the draw function, the locking piece of the locking handle (or crescent) is engaged with the receiving part of the mating stile of the other party, and its wedge action forces the inner and outer shoji from side to side.

<Problems with the prior art> However, in a shoji screen that does not have a middle crosspiece, when the wedge action occurs due to the rotation of the locking handle, it only bends the connecting stile, and the door stop side vertical stile does not have a wedge effect. There was a problem in that the wedge effect was not strong enough to ensure airtightness between the door stop side vertical stile and the satsushi vertical frame.

<Means for Solving the Problems> In view of the above-mentioned problems, the present invention reliably performs the draw function associated with the operation of the locking handle even for shoji without a middle crosspiece, and With the aim of improving the airtightness of the satsushi, the draw device has been designed with unique ingenuity.

That is, the present invention provides draw engagement parts on the top and bottom of the matching frame of one shoji that move up and down when the locking handle is operated. This is characterized in that a drawing receiving part that engages with the other shoji and has a wedge effect is provided at a position corresponding to the connecting part of the upper and lower horizontal stiles of the other shoji joining stile, or in the vicinity thereof.

<Example> An example of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic cross-sectional view showing a double-sliding sash according to the present invention, in which an inner sash A and an outer sash B are built into a sash frame S so that the sliding sashes can move in a double-sliding manner.

A locking device C having a locking handle 2 is attached to the shoji sill 1, and a pair of upper and lower elevating bodies 3, 4 that move up and down in conjunction with the rotation of the locking handle 2 are attached to the shoji sill 1. It is set inside 1. As the mechanism for converting rotational operation into vertical movement up and down, known means such as a rack and pinion or a combination of a rotating body and a link can be appropriately employed.

The upper elevating body 3 consists of an upper rod 5 and an upper engaging block 6, and this engaging block 6 is connected to the upper surface of the connecting base 6a with the upper rod 5 and to the inner shoji guide rail 8 of the sash upper frame 7. It is provided with a columnar wedge part 6b that engages, and a projecting part 6c that protrudes from the notch groove 9 formed in the facing facing surface A of the facing frame 1 of the outer shoji facing frame 10 on the outdoor surface. , the upper part of the projecting part 6c on the inner shoji opening direction has a wedge-shaped drawing engagement part 6d that tapers upward and faces the left sash vertical frame 11; At the upper part of the closing direction side, there is a pulling wedge part 6 that tapers upward and faces the indoor side.
It has e.

On the other hand, the lower elevating body 4 consists of a lower rod 12 and a lower engaging block 13, and this lower engaging block 13 has an inner shoji guide rail of the sash lower frame 14 on the lower surface of the connecting base 13a with the lower rod 12. 15, and protrudes toward the outer shoji sash 10 from a cutout groove 16 formed on the facing side 1 of the shoji sill 1 on the outside surface of the room (Fig. 6). ) At the lower part of the projecting part 13c on the inner shoji opening side, there is a wedge-shaped drawing engagement part 13d that tapers downward and faces the left sash vertical frame 11, and the inner shoji closing direction The lower part on the direction side has a drawing wedge part 13e that tapers downward and faces the indoor side.

The outer shoji B consists of upper and lower stiles 17 and 18, which are horizontal stiles, a matching stile 10, and a vertical stile 19 on the doorstop side. A receiving metal fitting 20, which is engaged with the projecting portions 6c, 13c of the engaging blocks 6, 13, is fixed.

The receiving metal fitting 20 is attached to one end of a base plate 20a that is screwed to the facing facing surface of the outer shoji sliding frame 10.
A mold piece 20c is provided with a drawing receiving part 20b on the same plane as the chimney return piece 10a, and a drawing receiving part 20d is bent and continuous on the other end, An inclined guide portion 20e is formed above and below a receiving portion 20d.

Such receiving metal fittings 20, 20 are used as a connecting frame 10.
Although it is installed so that it is on the same level as the upper and lower frames 17 and 18 connected to the upper and lower frames, when the inner and outer shoji A and B are opened and closed, it collides with the overhanging parts 6c and 13c that protrude to the outdoor side of the inner and outer shoji stile 1. So as not to,
The mounting positions of the receiving fittings 20, 20 are determined.

In addition, as shown in FIGS. 3 and 4, cutouts are provided at the upper and lower ends of the shoji to prevent the projecting parts 6c and 13c from colliding with the chimney return piece 10a of the outer shoji stile 10 when the inner and outer shoji are closed. 10b, 10b are formed, and the pulling receiving part 20b of the receiving fitting 20, which is flush with the chimney return piece 10a, is located at the notch 10.
b, 10b.

Next, the operation of this embodiment will be explained.

When the inner and outer shoji A and B are in a running state, the upper elevating body 3 is in the lowered position and the lower elevating body 4 is in the raised position, as shown in FIG. Therefore, when the inner shoji A is moved and closed as shown by arrow C in the figure, as shown in FIGS. 3 and 4, the projecting portions 6c and
13c is the chimney return piece 10 of the outer shoji frame 10
The cutout portion 10b formed in the portion a enters the cutout portion 10b, and vertically faces the receiving metal fittings 20, 20, respectively.

In this state, by rotating the locking handle 2, the upper elevating body 3 is raised and the lower elevating body 4 is lowered. As shown in FIGS. 5 and 6, each overhang 6c, The drawing engaging parts 6d, 13d of the drawing fittings 20, 20 engage with the drawing receiving parts 20d, 20d, and the drawing wedge parts 6e, 13e engage the drawing receiving parts 20b, 20b. engage.

As a result, the doorstop side frames 19, 21 of the inner and outer shoji A, B are pressed against the left and right sash frames 11, 22, and the connecting stile frames 1, 10 of the inner and outer shoji A, B are pulled together. They are brought together and become one body. or,
At this time, the columnar wedge portion 6b of the upper elevating body 3 presses and engages with the rail 8 of the sash upper frame 7, and the columnar wedge portion 13b of the lower elevator 4 presses and engages with the rail 15 of the sash lower frame 14. As the inner shoji A is drawn toward the indoor side, the sliding stile 1, 1 becomes one piece.
The outer shoji B is also pulled towards the indoor side via the 0.

As a result, the inner and outer shoji A, B can be brought into close contact with the inner circumferential surface of the sash frame S over their entire circumferences via the airtight material (partially omitted).

The above-mentioned receiving metal fittings 20 are respectively attached to the connecting frame 1.
0, the upper stile 17, and the lower stile 18 are fixed to the facing surface of the matching stile corresponding to the screwed connection parts, so that the engaging parts 6d, 13d for drawing and the receiving parts 20d, 20d for drawing are fixed. At the time of press engagement with the doorstop, the wedge action causes the joining frame 10 to deflect, and is reliably transmitted to the door stop side vertical frame 19 via the upper and lower frames 17 and 18.

Furthermore, as shown in FIG. 7, by providing a locking device D on the shoji sliding frame 1, the locked state can be maintained reliably.

This locking device D consists of an engaging body 23 rotatably held within a pedestal 22, and a receiving body 24 that moves up and down together with the rod 12 of the lower elevating body 4 when the locking handle 2 is rotated. Lower engagement protrusion 24 of receiver 24 in lowered position when locked
In this case, the engaging ends 23a of the engaging bodies 23 are engaged with each other to prevent the upward movement of the receiving body 24, thereby preventing the locking handle 2 from being inadvertently rotated.

Although the above-mentioned drawing engagement part is shown as a wedge-shaped part, it is not limited to this, and may be a rotating body protruding from the engagement block 6.

Further, although the receiving portion is provided within the width dimension of the horizontal stile, even if the receiving portion is installed somewhat outside the width dimension, the effect of the present invention will not change.

Furthermore, FIG. 8 shows another embodiment,
A receiving part 25 for pulling and a receiving part 26 for drawing are provided separately, and an overhang part 28 and an engaging part for drawing are provided with a wedge part 28a for drawing on the upper rod 27. It has an upper elevating body 3a which is separately provided with a projecting portion 29 provided with a projection 29a.

<Effects> As described above, the present invention provides a drawing engagement part on one shoji stile that can be raised and lowered by operating the locking handle, and each engages with this drawing engagement part. Since the receiving part that has a wedge effect is provided at a position corresponding to or near the connecting part of the upper and lower horizontal stile of the other shoji joining stile, the drawing engaging part and the receiving part engage with each other. The wedge action that occurs is reliably transmitted to the door stop side vertical stile via the horizontal stile, and the door stop side vertical stile and the sash vertical frame can be tightly attached without any gaps. Therefore, it is possible to eliminate the conventional drawback that the wedge action is not reliably transmitted to the doorstop side stiles due to the bending of the connecting stiles, and to provide a sash with excellent airtightness. That's what I'm doing.
