Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a shoji adjustment device for a so-called drake window, and in particular, it is easy to adjust the shoji to eliminate rattling when opening and closing the shoji. This invention relates to a shoji adjustment device for a drake window that can maintain the adjusted position semi-permanently and stably.

[Prior Art and Problems] As shown in FIG. 1, a drakep window has a window frame 1 that is fitted into an opening in a wall, for example, and a shoji 3 in which a window glass 2 is fitted. When the free end of the handle 4 provided on the free stile (the left stile in Figure 1) is directed downward, for example, as shown by the solid line, the shoji 3 is fixed to the window frame 1 (locked). , when the handle 4 is held horizontally as shown by the chain line, the shoji 3 can be rotated around the vertical axis of rotation that passes near the stile on the right side of the shoji 3, and cannot be opened inward like a normal window. (so-called dray state), and once the window is closed, if the handle 4 is further rotated so that its free end faces upward, the shoji 3 will rotate around the horizontal axis of rotation that passes through its lower stile. As shown in Figures 2 and 3, this is a window configured so that the shoji 3 can be tilted inward (so-called "keep" state) for ventilation, etc., and its overall configuration has been known for a long time. It is.

The mechanism for shifting the shoji 3 from the draped state to the closed state is roughly described below. That is, as shown in FIGS. 4 and 5, the guide groove 5 (the eighth
(see figure) includes a drive rod 6, this drive rod 6
A stay arm receiver 7 and a stay arm guide 8 connected to the tip of the stay arm 1 are slidably guided.
1 is linked to the free end of 1. As shown in FIGS. 4 and 7, the stay arm 11 is rotatably supported and guided by a hinge 9 fixed to the indoor side of the window frame 1.

In the dray state, as shown in FIG. 4, the connecting member 12 such as a roller protruding from the lower surface of the base end of the stay arm 11 is inserted into the receiving groove 13 formed on the upper surface of the stay arm receiver 7. It's involved. Therefore, the shoji 3 is the stay arm 1.
1 and supported by a hinge 9, which enables the above-mentioned inward opening rotation.

On the other hand, when transitioning to the locked state, the drive rod 6 moves to the left in FIG. 4 in conjunction with the rotation of the handle 4 (FIG. 1), and the engagement between the connecting member 12 and the receiving groove 13 is released. Then, the stay arm 11 of the shoji 3 is swung out toward the interior of the room (see FIG. 5), and the shoji 3 is inverted (see FIGS. 2 and 3).

Therefore, in order to ensure smooth operation, gaps are provided between the stay arm receiver 7 and the inner surface of the guide groove 5, and between the receiver groove 13 and the connecting member 12. The shoji 3 becomes movable by the amount of play relative to the stay arm 11, and the shoji 3 wobbles when opening and closing, making it difficult to use.

In order to prevent this wobbling, for example,
As described in Japanese Patent No. 28658, the crimping shaft 10 (see Fig. 5) of the connecting member 12 to the stay arm 11 is set eccentrically so that the receiving groove 13 of the connecting member 12 is A shoji adjustment device for adjusting the position has been proposed.

However, in this shoji adjustment device, when the shoji 3 is opened and closed, the side surface of the receiving groove 13 is
Since a rotational moment is applied to the caulking shaft 10 of
There is an inconvenience that the crimping shaft of the connecting member 12 becomes loose after a certain period of use, causing wobbling.

[Object of the Invention] Therefore, an object of the present invention is to provide a shoji adjustment device for a drake window, which eliminates the above-mentioned disadvantages and can stably fix the adjustment position of the connecting member once set.

[Means for Solving the Problems] In order to achieve the above object, the present invention has a window frame and a shoji, and a guide groove formed on the upper edge of the shoji has a drive rod, and the drive rod is provided with a drive rod. The stay arm holder is connected to the tip of the stay arm with a receiving groove formed on its upper surface, and the stay arm guide is slidably guided, while the base end of the stay arm is rotatably supported inside the window frame. The free end is linked to the stay arm guide, and a connecting member is integrally provided on the lower surface of the base end of the stay arm, and when this connecting member is engaged with the receiving groove of the stay arm receiver, the shoji is not connected to the stay arm guide. It pivots integrally with the arm, and when the drive rod slides in the direction away from the connecting member, the receiving groove of the stay arm receiver disengages from the connecting member, allowing the shoji to tilt inward. In the drake cup window, the stay arm receiver is divided into a guide block which is restrained by a guide groove on the upper edge of the shoji, and a receiving block with a receiving groove formed therein, and the upper edge of the shoji is attached to the mutually opposing joint surfaces of the two. A large number of serration grooves are formed substantially parallel to the longitudinal direction of the guide block, and at least one female threaded hole is opened in the guide block;
A long screw hole is opened in the direction perpendicular to the serration groove in the part of the receiving block that aligns with the female screw hole in the length direction of the serration groove, and a screw inserted into the screw hole and screwed into the female screw hole is used to connect the guide block to the guide block. It is characterized in that it is screwed to the receiving block in a state in which it is engaged with the serration groove so that the engagement position of the serration groove can be changed.

An embodiment of the present invention will be described below with reference to the drawings.

[Embodiment] In FIG. 6, the reference numeral 14 indicates the entire guide block, and this guide block 14 has, for example, the guide groove 5 of the shoji (see FIG. It is a block body integrally formed with a pair of sliding contact shoes 15, 15 that enter the guide block 14 (see), and has a large number of serrations on its upper surface that are approximately parallel to the length direction of the guide block 14 (the length direction of the upper edge of the shoji). (serration: sawtooth cut in cross section) Groove 1
6 and 16 are formed at equal pitches.

Further, in the central part of the guide block 14, for example, two female screw holes 17, 17 are provided along the length direction.
is open, and an engagement pin 18 (see FIG. 4) is integrally protruded from the lower surface of one end of the guide block 14.

On the other hand, in FIG. 6, reference numeral 19 indicates a receiving block, and this receiving block 19 has a stepped lower surface (not shown) so that it can be joined to the upper surface on which the serration grooves 16, 16 of the guide block 14 are formed. A serration groove (not shown) is formed on the lower surface of the block body facing the guide block 14 to engage with the serration groove on the upper surface of the guide block.

Further, a receiving groove 13 similar to that of the stay arm receiver 7 (FIG. 5) is formed at one end of the upper surface of the receiving block 19, and furthermore, a receiving groove 13 is formed at the other end in a direction perpendicular to the serration groove. Two long countersunk screw holes 21, 21 are opened at the bottom.
The distance between these countersunk screw holes 21, 21 is determined to be the same as that of the internal threads 17, 17 in the guide block 14.

The guide block 14 and the receiving block 19
As shown in FIG. 7, with a large number of serration grooves 16, 16 formed on the mutually opposing joint surfaces of the two being engaged so that the engagement position can be changed, the two are integrally connected to each other by, for example, countersunk screws. are coupled together to form a stay arm receiver 70.

Similar to the conventional stay arm receiver 7 (see FIG. 5), this stay arm receiver 70 has an engagement pin 18 protruding from its lower surface and a connecting hole 22 opened at the tip of the drive rod 6. (FIG. 5), it is integrally connected to the drive rod 6 (see FIG. 8).

[Function] In the shoji adjustment device for a drake cap window according to an embodiment of the present invention configured as described above, when assembling and adjusting the drake cap window, the handle 4 (FIG. 1) is rotated to connect the connecting member (not shown). Slide the drive rod 6 (Figs. 4 and 5) through the retainer to check the contact between the side surface of the receiving groove 13 of the stay arm holder and the connecting member 12 (Fig. 4) that engages in this receiving groove 13. Make sure that the rattling of the shoji in the dray state is as small as possible.

Specifically, the stay arm receiver 70 shown in FIG.
Loosen the countersunk screws, and with the receiving block 19 floating from the guide block 14, normally move the receiving block 19 to the left in FIG.
6 are engaged again, and the adjustment position of the receiving block 14, that is, the connecting member 12 in the receiving groove 13.
The adjustment position is automatically determined.

As shown in FIG. 8, the distance between the connecting member 12 and the side surface 13a on the outdoor side of the receiving groove, and the distance between the sliding contact shoe 15 on the outdoor side of the guide block and the inside surface of the guide groove 5 are minimized. When adjusted in this manner, rattling in the direction in which the shoji 3 moves to the left with respect to the stay arm 11 is prevented.

In addition, the play in the direction in which the shoji 3 moves to the right in FIG. 8 is caused by, for example, the outer protruding edge 23a of the shoji edge 23 (see FIG. 4) that is integrally formed on the edge of the indoor side of the shoji 3. and the inner surface of the stay arm support block 24 of the hinge 9 (see FIGS. 4 and 7), which rotatably supports and guides the stay arm 12, are in contact with each other in the dray state. This can be effectively prevented by making appropriate settings (see Figure 7).

Note that the amount of adjustment of the relative position between the connecting member 12 and the receiving groove 13 can only be set in stages because it is based on changing the engagement position of the serration grooves 16, 16; The amount of gap between the serrations 16 can be made less than the pitch of the serrations 16 (for example, 0.5 to 0.7 mm), and the rattling caused by such a small gap causes almost no problem in practice.

[Effect] As is clear from the above description, the present invention divides the stay arm receiver into a guide block that is restrained by a guide groove formed on the edge of the shoji and a receiving block that has a receiving groove, and Since a large number of serration grooves formed on the joint surface are connected in an interlocking state so that the engagement position can be changed, in principle, the adjustment position once set can be maintained stably semi-permanently.

In addition, the receiving block can be moved for adjustment by simply loosening the connection between the receiving block and the guide block, and the adjustment position is automatically set by simply placing the receiving block on the guide block.
It has various effects, such as making it extremely easy to adjust the shoji screen and not requiring any special adjustment tools.
