Description

  The present invention relates to an open window in which a shoji is attached to a window frame so as to be opened and closed with a window stay, and to the window stay.

Various types of window stays are known for use in open windows.
For example, a window stay disclosed in Patent Documents 1 and 2 is known.
In the window stay disclosed in Patent Document 1, a slider is slidably attached to a base, a first arm is pivotally connected to the slider with a connecting pin, and the first arm is connected to one end of a shoji mounting plate. The second arm is pivotally connected to the other end of the shoji mounting plate and the base, and the slider is slid in one direction along the base. The shoji mounting plate is in a closed position where it overlaps the base, and the sliding plate is slid in the other direction along the base so that the shoji mounting plate protrudes from the base.
The sliding window using this window stay is attached with the base fixed to the window frame and the shoji attached to the shoji mounting plate. The shoji mounting plate is moved to the open position by operating the shoji in the opening direction. The shoji mounting plate is rotated toward the closed position by operating the shoji in the closing direction, and when the shoji is in the closed state, the shoji mounting plate is in the closed position.

The base and first and second arms of the window stay are made of metal, but the slider is made of synthetic resin so that it slides smoothly and can be easily manufactured even in complex shapes. The slider may melt.
As described above, when the slider is melted by heat, the first arm is in a free state with respect to the base. Therefore, one end of the shoji mounting plate is detached from the base, and the shoji mounting plate is attached to the base via the second arm. And can be freely rotated.
For this reason, the sliding window using the window stay disclosed in Patent Document 1 described above causes the shoji to fall out of the window frame when the slider is melted by heat or the like.

In the window stay disclosed in Patent Document 2, a metal reinforcing plate is fixed to a pin connecting a synthetic resin slider (slider) and a first arm (a small connecting arm), and the metal reinforcing plate is a base ( Since the length of the mounting rail is longer than that between the rails on both sides, the metal reinforcing plate is held in the recess between the rails when the slider is melted by heat, and one end of the shoji mounting plate does not come off the base.
The sliding window using the slider does not drop the shoji from the window frame even if the slider is melted by fire or the like.

  Although the sliding window using the window stay disclosed in Patent Document 2 described above does not fall out of the window frame even if the slider is thermally melted due to a fire or the like, the metal reinforcing plate is used to prepare a metal reinforcing plate. It takes extra time to manufacture, extra parts, and extra work to fix the metal reinforcing plate to the pins, which increases the number of man-hours for assembling the window stays. Windows are expensive.

In addition, the support protrusion provided at the other end in the longitudinal direction than the positioning pin of the base is fitted to the support recess provided in the window frame, so that it is supported by the window frame so as not to move in the shoji opening / closing direction. Therefore, even if negative pressure acts on the shoji due to heavy wind and rain, the base does not come off and the shoji does not fall off the window frame.

As shown in FIG. 1, a shoji 2 is attached to a window frame 1 by a pair of window stays 3 so as to be opened and closed, thereby forming an open window.
The window frame 1 is rectangular with an upper frame 10, a lower frame 11, and left and right vertical frames 12.
The shoji 2 has an upper gutter 20, a lower gutter 21, and left and right vertical gutters 22 connected in a rectangular shape, and a panel 23 such as glass is mounted therein.
In this embodiment, the window stays 3 are respectively attached to the left and right vertical frames 12 and the left and right vertical rods 22.

As shown in FIGS. 2 to 6, the window stay 3 includes a base 30, a slider 31 that slides along the base 30 between the first position and the second position, and the slider 31. A first arm 33 pivotally connected by a connecting pin 32, a shoji attachment plate 34 pivotally connected to the first arm 33, and a pivot between the shoji attachment plate 34 and the base 30. A connected second arm 35 is provided.
The base 30, the connecting pin 32, the first arm 33, the shoji mounting plate 34, and the second arm 35 are made of metal, and the slider 31 is made of synthetic resin.
When the slider 31 is in the first position shown in FIG. 2, the shoji mounting plate 34 is in an open position protruding to one side in the width direction of the base 30.
When the slider 31 is in the second position shown in FIG. 4, the shoji mounting plate 34 is in a closed position overlapping the base 30.
That is, the window stay 3 is the same as a normal window stay.

As shown in FIG. 1, the window stay 3 is attached with the base 30 fixed to the vertical frame 12 with a fixing tool. For example, it is fixed and attached with screws 13.
The shoji mounting plate 34 is fixedly attached to the vertical rod 22 of the shoji 2 with a fixing tool. For example, the screws 24 are fixed and attached.
The shoji 2 is opened by setting the shoji mounting plate 34 to the open position shown in FIG. 2, and the shoji 2 is closed by setting the shoji mounting plate 34 to the closed position shown in FIG.

In short, the base 30 is attached to the vertical frame 12 such that the width direction of the base 30 is in the shoji opening / closing direction and one side in the width direction is the shoji opening direction.
When the slider 31 is in the first position, the shoji attachment plate 34 protrudes in the shoji opening direction from the window frame 1 and the shoji 2 is opened.
When the slider 31 is in the second position, the shoji mounting plate 34 is housed in the window frame 1 and the shoji 2 is closed.
In the embodiment shown in FIG. 1, the base 30 is mounted in the vertical direction, the first arm 33 is located near the upper portion of the base 30, the second arm 35 is located near the lower portion, and the slider. 31 moves up and down in the upper part of the base 30, and the second position is higher than the first position.

The base 30 has a support piece 36 closer to one side in the width direction (that is, closer to the sliding door opening direction).
As shown in FIG. 4, the connecting pin 32 faces the support piece 36 when the slider 31 is in the second position, that is, the shoji mounting plate 34 is in the closed position, and is located on the other side of the support piece 36 in the width direction. It is located close to the shoji (closer side), and its connecting pin 32 comes into contact with the support piece 36 so as not to come off if it tries to protrude in one side in the width direction of the base 30 (the direction of arrow a in FIG. 4). .
In other words, the support piece 36 is located on the side of the shoji opening with respect to the connecting pin 32.
As such, when the shoji 2 is closed and the slider 31 is thermally melted due to a fire or the like and the shoji 2 tries to move in the opening direction with respect to the window frame 1, the connecting pin 32 becomes a support piece for the base 30. The base 30 is held by the base 30 without coming out of contact with the base 36 and coming off one side in the width direction of the base 30.
Therefore, the shoji 2 does not fall out of the window frame 1 when the slider 31 is thermally melted with the shoji 2 closed.

  Further, since the connecting pin 32 of the normal window stay is brought into contact with the support piece 36 provided on the base 30, there is no need to provide special parts as in the conventional case, the number of parts is small, and the assembly work is easy. Since the cost of the window stay is low, it can be made an inexpensive open window.

In this embodiment, the support piece 36 of the base 30 is provided over substantially the entire length of the base 30 in the longitudinal direction, and the connecting pin 32 faces the support piece 36 even when the slider 31 is in the first position. 30 so as not to come off to one side in the width direction.
Thereby, even if the slider 31 is thermally melted when the shoji 2 is open, the shoji 2 does not fall out of the window frame 1.

A specific shape of the window stay 3 will be described.
The base 30 has a narrow and long plate-shaped mounting plate 30a, a rising piece 30b provided on one side in the width direction of the mounting plate 30a, and a rising plate 30c provided on the other side in the width direction of the mounting plate 30a. A lateral plate 30d facing the mounting plate 30a provided at the upper end of the rising plate 30c, and a support piece 30e facing the mounting plate 30a provided on the lateral plate 30d, and a guide recess 30f on the other side in the width direction. have. The base 30 is manufactured by bending a single plate.
The guide recess 30f is open to one side in the width direction.
The rising piece 30b is the support piece 36 and continues from one end in the longitudinal direction (lower end in FIG. 2) to the other end in the longitudinal direction (closer to the upper end in FIG. 2).

The lower surface 31a of the slider 31 is slidably in contact with the mounting plate 30a of the base 30, and the lower surface 31a has a lower guide groove 37 into which the support piece 36 is slidably fitted. Has a guide groove 38 into which the support piece 30e is slidably fitted, and the other side in the width direction of the slider 31 is slidably fitted into the guide recess 30f of the base 30. A hole (stepped hole) 39 is formed between the lower guide groove 37 and the upper guide groove 38, and the hole 39 is positioned closer to the shoji closing side than the lower guide groove 37.
Accordingly, the slider 31 is attached to the base 30 so as to be slidable in the longitudinal direction and not to move in the width direction.
The connecting pin 32 is inserted into the hole 39 of the slider 31, and the lower surface of the connecting pin 32 faces the mounting plate 30a.

As described above, the slider 31 slides along the support piece 36 of the base 30 and the connecting pin 32 does not move in contact with the support piece 36. Therefore, the slider 31 moves smoothly and the metal There is no sound.
Further, the overall length of the window stay 3 can be lowered by shortening the protruding length of the support piece 36 of the base 30.

The connection pin 32 includes a large-diameter support shaft portion 32a fitted in a hole (stepped hole) 39 of the slider 31 and a small-diameter connection shaft fitted in a hole 33a at one end in the longitudinal direction of the first arm 33. A portion 32b is inserted through the hole 39 of the slider 31, the connecting shaft portion 32b is inserted into the hole 33a, and the step portion between the support shaft portion 32a and the connecting shaft portion 32b is opened to the hole 33a of the first arm 33. The connecting shaft portion 32b of the connecting pin 32 is supported and fixed so as not to come out of the first arm 33 by crimping the portion protruding from the hole 33a of the connecting shaft portion 32b in contact with the edge. One end of one arm 33 in the longitudinal direction is rotatably connected. The portion where the first arm 33 of the slider 31 is connected is thinner than the other portions.
The lower surface of the support shaft portion 32 a of the connecting pin 32 faces the mounting plate 30 a of the base 30, and the outer peripheral surface faces the support piece 36.
As described above, a part of the slider 31 is interposed between the support piece 36 and the outer peripheral surface of the connecting shaft portion 32a. When the slider 31 slides during normal operation, the connecting pin 32 (the outer periphery of the supporting shaft portion 32a) is interposed. The surface) does not touch the support piece 36, moves smoothly, and does not cause metal noise. When the slider 31 is melted by heat, the connecting pin 32 is fixed to the first arm 33, and the connecting pin 32 (outer peripheral surface of the support shaft portion 32 a) is in contact with the support piece 36.

The other end in the longitudinal direction of the first arm 33 is rotatably connected to one end in the longitudinal direction of the shoji mounting plate 34 by the first pin 40, and the second arm 35 is connected to the middle in the longitudinal direction of the shoji mounting plate 34 . One end portion in the longitudinal direction is rotatably connected by the second pin 41, and the other end portion in the longitudinal direction of the second arm 35 is rotated by the third pin 42 to the other end portion in the longitudinal direction of the base 30 (mounting plate 30a). It is connected freely.
The first arm 33 is provided with a guide pin 43, and the guide pin 43 has a groove 43 a that is slidably fitted into the support piece 36.

As shown in FIG. 2, when the slider 31 is in the first position, the slider 31 is in contact with the positioning pin 44 so that it can be positioned and held so as not to slide toward the other end in the longitudinal direction from the first position. .
As described above, when the slider 31 is in the first position, the groove 43a of the guide pin 43 of the first arm 33 is fitted into the support piece 36, and the first arm 33 is located on one side in the width direction of the base 30 shown in FIG. Hold firmly in an overhanging posture.
Accordingly, the shoji mounting plate 34 is firmly held by the second arm 35 and the first arm 33 in the open position shown in FIG.

When the slider 31 slides in the direction of arrow b in FIG. 2 from the state shown in FIG. 2 toward the second position, the first arm 31 moves in parallel because the guide pin 43 slides along the support piece 36. .
When the guide pin 43 is detached from the support piece 36, the guide pin 43 comes into contact with the guide surface 45a of the stopper / guide piece 45 attached to one end of the base 30 in the longitudinal direction, and the width of the guide pin 43 is changed along the guide surface 45a. By sliding toward the side, the first arm 33 rotates with respect to the slider 31, and as shown in FIG. 4, the shoji mounting plate 34, the first arm 33, and the second arm 35 overlap and overlap the base 30. Closed position.

Next, attachment of the base 30 will be described.
Since the slider 31 is movably attached between the first position and the second position at a portion closer to the other end in the longitudinal direction of the base 30 (upward portion in FIGS. 2 and 4), A portion closer to one end in the longitudinal direction (portion closer to the lower side in FIGS. 2 and 4), that is, the remaining portion in the longitudinal direction other than a portion in the longitudinal direction in which the slider 31 moves is fixedly attached to the vertical frame 12 with the screws 13 described above.
For example, a through hole 50 is formed in a portion of the mounting plate 30a of the base 30 near one end in the longitudinal direction, and the screw 13 is fixedly attached to the vertical frame 12 through the through hole 50.

By mounting in this way, the slider 31 and the connecting pin 32 do not move along the screw 13 that attaches the base 30 to the vertical frame 12, so that the connecting pin 32 contacts the surface of the mounting portion 30a of the base 30. Or can be opposed to each other with a slight gap.
Therefore, since the protruding length of the support piece 36 of the base 30 (the protruding length from the mounting portion 30a) can be shortened so that the outer peripheral surface of the connecting pin 32 faces the support piece 36, the overall height of the window stay 3 can be increased. Can be lowered.

  Further, since there is no screw 13 in the portion where the slider 31 moves and the slider 31 does not get in the way when screwing, the slider 31 is in the first position and the shoji mounting plate 34 protrudes to one side in the width direction of the base 30. Since the base 30 can be fixed and attached to the vertical frame 12 with screws 13 as a state, the operation is simple.

  When the base 30 is attached to the vertical frame 12 as described above, the portion closer to the other end in the longitudinal direction of the base 30 (the portion where the slider 31 is moved) is not fixed to the vertical frame 12, so that it acts on the shoji 2 during strong wind and rain. When the base 30 is pulled in the opening direction of the shoji by the negative pressure, the screw 13 is removed, and the base 30 may be detached from the vertical frame 12 and the shoji 2 may fall off the window frame 1.

Therefore, the longitudinal direction other end portion of the base 30 (mounting plate 30a) is supported by the vertical frame 12 so as not to move in the door opening / closing direction.
For example, a support protrusion is provided at a portion near the other end in the longitudinal direction of the mounting plate 30a of the base 30 so as to protrude from the back surface (the surface in contact with the vertical frame 12) of the mounting plate 30a.
Preferably, a part of the mounting plate 30 a is cut and raised to form the support protrusion 51.
As shown in FIGS. 7 and 8, a support recess is formed in which the support protrusion fits into the base mounting portion of the vertical frame 12.
Preferably, the base mounting plate 52 is fixed to the vertical frame 12, and the screw 13 is screwed into the hole 53 of the base mounting plate 52 so that the portion near the other end in the longitudinal direction of the base 30 is fixed.
A support recess 54 is formed in the base mounting plate 52, and a support protrusion 51 is fitted into the support recess 54 to support the portion near the other end in the longitudinal direction of the base 30 so as not to move in the shoji opening / closing direction.

In addition, with the shoji mounting plate 34 fixedly attached to the vertical rod 22 of the shoji 2, the shoji 2 is held by hand from the shoji opening side (outside of the window frame 1) and pushed into the window frame 1 for support. When the protrusion 51 is elastically deformed in contact with the base mounting plate 52 and is pushed to a predetermined position, the support protrusion 51 is fitted into the support recess 54 and the base 30 is supported by the base mounting plate 52, and the base 30 is The shoji 2 is temporarily attached to the window frame 1 by being in contact with the inwardly facing piece 52 a of the base mounting plate 52 and positioned in the shoji opening / closing direction.
In this state, the base 30 is fixedly attached to the vertical frame 12 by screwing the screw 13 into the hole 53 of the base mounting plate 52 from the through hole 50 in the portion (lower portion) near one end in the longitudinal direction of the base 30.
As such, the shoji 2 can be easily attached to the window frame 1.
