Description

[Detailed description of the invention] Industrial field of application When a shoji is closed, one shoji of a sliding sash is placed on the same plane as the other shoji, or the shoji is placed on the same plane as the fitting part of a one-sided sash. In recent years, there has been a demand for a sash with a simplified design as a whole, and sashes that meet this demand to some extent have been successively proposed, but the present invention is primarily concerned with a sliding door shoji used for such a sash. This invention relates to an indoor/outdoor direction displacement device for a door.

Conventional technology For example, as described in Jitsima J55-74379, upper and lower arcuate grooves are provided on the vertical frame side of the upper and lower window frames and curved while gradually approaching the vertical direction from the indoor side to the outdoor direction. The rolling ball provided at the bottom of the door precedent is engaged with the lower arc-shaped groove, and the vertically rotating roller provided at the upper part is engaged with the upper arc-shaped groove, and when the shoji is closed, the rolling ball is transferred along the lower arc-shaped groove, and the roller There is a structure in which the shoji door tip is rotated along an upper arcuate groove, and the tip of the shoji door is inserted into the interposed gap formed by the water jungle provided inside the vertical wall and the receiving member.

Problems to be Solved by the Invention In the conventional example described in the above-mentioned publication, the rolling balls and rollers do not displace with respect to the shoji, but are attached to the shoji so that they roll or rotate depending on the position.

Therefore, when displacing the shoji in the indoor/outdoor direction, the shoji door end must be moved at the same time as the shoji door tip, as described in the above-mentioned publication. In other words, after placing a rolling ball or roller at the base position of the arcuate groove from the indoor side, it is necessary to press the entire shoji toward the outdoors, and a series of operations to move the shoji door tip toward the vertical frame. This is not enough, and the above-mentioned suppression operation is required in addition to the movement operation.

The present invention focuses on the drawbacks of such conventional examples, and provides a sliding door shoji door end indoor direction displacement device that can perform an indoor/outdoor displacement operation (opening/closing operation) of a shoji door end by operation in only one direction. It was created for this purpose.

Means for solving the problem A pair of upper and lower arm pieces are rotatably attached to a shoji door, and a pair of guide rollers rotatably attached to the free ends of these arms are attached to the upper and lower window frames. The structure is such that the guide gap is engaged with the guide gap provided in the guide gap.

The glass panels 9 of the inner shoji B are placed on the same plane as the glass panels 9' of the outer shoji B' when closed. That is, the upper side of the inner sash B is supported by the hanging wheels (not shown) via the arm pieces (not shown), and the lower side of the inner sash B is supported by the rollers (not shown) via the arm pieces (not shown). By assembling it on the lower frame 1b with a pivot, each arm piece is rotatably attached to the shoji side, the hanging wheel side, etc.
The inner shoji B is in a state where it can be displaced both indoors and outdoors, and the drawing shows an example in which the present invention is applied to the door edge side of this inner shoji B.

Therefore, the right vertical frame 1 of the straight upper guide rails 3, 3
The end on the c side is cut out and the upper guide block 10 is engaged with the cutout and fixed to the upper frame 1a. An upper guide gap WA12 communicating with the base 1 is provided, and the upper guide gap 12 communicates with the base 1.
As it approaches the right vertical frame 1c from 2', it gradually approaches the outdoor side.

Further, the end of the linear lower guide groove 5 on the right vertical frame 1C side is notched in the same way as the upper guide rails 3, 3, and the lower guide block 13 is engaged with the notch, so that the lower frame 1b This lower guide block 13 is provided with a lower guide gap 14 that communicates with the lower guide groove 5, and the lower guide gap 14 gradually moves toward the outside of the window frame as it approaches the right vertical frame IC from the base 14'. It is in a bent shape close to.

A piece 15 is installed inside the right vertical frame 1c at the middle part in the indoor/outdoor direction.
A water jungle 16 with its tip facing indoors is provided on the piece 15, and the supporting piece 7 is attached to the right vertical frame 1c so as to face the indoor side of the water jungle 16. , a holding roller 18 facing the water jungle 16 is attached to the support piece 17.
The inner shoji B is supported so as to be rotatable on its vertical axis, and the clamping roller 18 and the moisture jungle 16 constitute a clamping gap 19, and a shoji door tip 20 that matches the clamping gap 19 is provided.
An upper arm piece 21 is rotatably attached to the upper surface of the 20 door tips 2.

Further, a lower arm piece 24 is rotatably pivoted 25 on the lower surface of the door edge 20 side of the inner shoji B, and a pair of lower guide rollers 26 and 28 are rotatably mounted on the tip of the lower arm piece 21 on a vertical axis. The lower guide rollers 26, 26 are engaged with the lower guide groove 5 or the lower guide gap 14.

As mentioned above, FIG. 1 is an explanatory view of the arrangement of each part, but this figure also shows the shoji in a closed state. To obtain this shoji closed state, first move the outer shoji B' to the left vertical frame 1d along the upper guide piece 2 and the lower guide rail 4, and then move the hanging wheel (not shown) to the upper guide rail 3. Run along 3,
Moreover, when a roller (not shown) is moved along the lower guide groove 5, the door edge 20 of the inner shoji B gradually approaches the right vertical frame lc, and the upper door edge 20, which has moved along the gap 11 with the approaching movement, approaches the right vertical frame lc. Guide roller 23. 23 is the base 8p12' of the upper guide gap 12
The lower guide rollers 26, 26, which have reached the position and moved along the lower guide groove 5 at the same time, touch the base 1 of the lower guide gap 14.
This will lead to the 4' position.

Then, if the movement operation of Najinko B is continued,
Since the external force due to the movement operation is applied to the inner sash B in the direction of the right vertical frame IC, the upper guide rollers 23, 23 move into the upper guide gap 12, and the lower guide rollers 26, 26 move into the lower guide gap 14. As a result, the upper and lower arm pieces 21 and 24 rotate around the pivot points 22 and 25,
The upper arm piece 21 and the lower arm piece 24 rotate along the upper guide gap 12 of the upper guide roller 23 and along the lower guide gap 14 of the lower guide roller 26, respectively, and rotate in response to the movement. When the door tip 20 of B is inserted into the insertion gap 19, the rotation is stopped and a closed state of the shoji as shown in FIG. 1 is obtained.

Of course, to obtain the shoji open state, the operation can be performed in the opposite manner to the above.

In the example, this device is applied to a sliding sash, but a fitting part is provided on one side of the window frame, and when the shoji is opened, it overlaps with the fitting part in the indoor/outdoor direction, and when the sash is closed, the fitting part is closed.
