Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an opening / closing device and a fitting for interlocking closing movement of a face material with locking and unlocking.

For example, a horizontal axis rotating window in which ventilation is performed by naturally opening and closing a shoji supported by a window frame is known as a fixture for opening and closing a facing relative to a frame (for example, a patent) Reference 1).
The horizontal axis rotation window supports the shoji in an eccentric state by arranging the horizontal rotation axis on the upper side with respect to the center position in the height direction of the shoji. In addition, a weight is attached to the upper side of the pivotal support position of the shoji and on the indoor side of the shoji, so that the lower end of the shoji will open to the outdoor side when there is no wind, and it is set to naturally open. ing.
Furthermore, when the wind hits Shoji from the outdoor side, the lower end side of the shoji moves indoors, and the shoji can be put in a closed state, since the shoji has a large area below the pivotal support position.
Therefore, if the wind pressure is relatively low, the shoji can be naturally opened and ventilated, and if a strong pressure equal to or greater than a predetermined value is applied to the shoji, such as strong wind blowing from the outdoor side to the indoor side. , Shoji can be closed automatically.

The horizontal axis rotation window is provided with a shoji opening and closing device for forcibly closing or opening the shoji, and a lock device for locking the shoji in a closing state.
The shutter opening / closing device includes an opening / closing arm with a rubber roller rotatably supported by the vertical frame member of the window frame, and a linear actuator for rotationally driving the opening / closing arm. The opening and closing arm is rotationally driven by the linear actuator, and the upper rubber roller of the opening and closing arm is brought into contact with the upper side of the support shaft of the longitudinal rod of the shoji, thereby closing and moving the shoji. Further, the opening / closing arm is rotated in the opposite direction so that the lower rubber roller is brought into contact with the lower side of the vertical shaft of the vertical hook of the shoji, thereby moving the shoji open.
The lock device includes a slider slidably guided on a rail provided on the lower frame member of the window frame, a linear actuator for moving the slider along the rail, a lock pin attached to the slider, and a lower edge of the shoji And a lock provided.
Then, when closing the shoji with the shoji opening and closing device, the lock device is once driven to move the slider to a predetermined position before operating the shoji opening and closing device, and then the shoji opening and closing device is driven to make the shoji using the opening and closing arm. Close. Thereafter, the locking device is driven again to move the slider, and the locking pin is engaged with the locking device of the shoji to lock the shoji closed.
In order to unlock the shoji, the slider is moved by the linear actuator, and the lock pin is unlocked by moving from the engagement position with the locking tool.

JP, 2005-146544, A

By the way, in the horizontal axis rotation window described in Patent Document 1, the linear actuator of the shutter opening / closing device rotationally drives the opening / closing arm, and the linear actuator of the locking device slides the slider. Therefore, the operating strokes of the linear actuators are different, and the operation timings of the shutter switching device and the locking device are also different.
Therefore, it is necessary to provide separate independent linear actuators in the shoji switching device and the lock device, and it is necessary to adjust and control the drive timing of each linear actuator. Therefore, the drive control of each linear actuator becomes complicated, the cost increases, and further, since a plurality of linear actuators are required, it is difficult to achieve compactness.

In addition, since the shoji opening and closing device and the lock device are operated by separate actuators, when closing the shoji, after moving the slider to a predetermined position as described above, the shoji is closed by the opening and closing arm, and then It is necessary to drive the locking device again to move the slider. Therefore, after driving of one actuator is completed, the other actuator must be driven, and control such as switching of the driving of the linear actuator between the shutter opening / closing device and the lock device is executed reliably at the set timing. It is difficult to do.
Such a subject is not limited to the horizontal axis rotary window of Patent Document 1, but also a frame body such as a window frame or a door frame, and a face material such as a shoji or door supported openably and closably with respect to the frame. This is a problem common to the opening and closing device provided with the closing mechanism for closing the face material and the locking mechanism for locking and unlocking the face material.

  An object of the present invention is to provide an opening and closing device and a joint that can perform closing movement, locking and unlocking of a facing with a simple configuration.

The opening and closing device according to the present invention is an opening and closing device capable of opening and closing the facing of the fitting including a frame and a facing, the closing mechanism capable of moving the facing to a closing position, and the face in the closing position. And a locking mechanism capable of locking the material, wherein the closing mechanism can move forward from the first position to the third position via the second position along the frame and from the third position The slider includes a movable body capable of returning to the first position via the second position, and a drive device for reciprocatingly driving the movable body, and the movable body is a slider capable of reciprocating along the frame. And a contact member attached to the slider, wherein the locking mechanism comprises a linkage member contacting the contact member and a lock portion capable of interlocking with the movement of the linkage member; The linkage bar and the linkage bar And a locking contact piece connected to the linkage bar, wherein the locking contact piece and the unlocking contact piece move in the moving direction of the linkage member. The locking contact pieces are disposed in such a manner as to move the linkage member in the locking direction so as to be movable in the locking direction, in the forward movement of the slider. The piece is disposed so as to be movable in the unlocking direction opposite to the locking direction in contact with the contact member at the time of the return movement of the slider, and the locking portion is a portion of the linkage member The face material can be locked based on movement in the locking direction, while the face material can be unlocked based on movement of the linkage member in the unlocking direction, and the closing mechanism Before the first position of the body The face material can be moved to the closed position based on forward movement to a second position, and the locking mechanism is configured to move based on forward movement of the movable body from the second position to the third position. The face member can be locked, and the closing mechanism can open the face member based on the movement of the movable body from the second position to the first position, and the locking mechanism can It is characterized in that the face material can be unlocked based on the movement of the movable body from the third position to the first position.

According to the present invention as described above, the closing mechanism and the locking mechanism can be interlocked with each other by a simple configuration in which the movable body is reciprocated.
That is, since the movable body can move forward from the first position to the third position, the movement of the movable body from the first position to the second position and the movement of the movable body from the second position to the third position Can be done continuously. Therefore, the movement of the face material to the closing position by the closing mechanism, which is performed while the moving body moves from the first position to the second position, and the row while the moving body moves from the second position to the third position There is no need to control the timing of switching between the locking operation of the facing by the locking mechanism to be performed by the control device or the like by the control device etc., and only moving the moving body from the first position to the third position via the second position The movement of the face material to the closed position by the mechanism and the locking of the face material by the locking mechanism can be reliably performed at the set timing, and the switching from the closing movement to the locking can be smoothly performed.
Further, in the movement (return movement) from the third position to the first position of the movable body, the movable body can be moved from the second position to the first position. For this reason, the moving operation which enables the face material to be released by the closing mechanism, which is performed while the movable body moves from the second position to the first position, and the line during the movement of the movable body from the third position to the first position It is not necessary to control the timing to execute the unlocking operation of the surface material by the locking mechanism to be performed by the control device etc., and only by moving the movable body from the third position to the first position via the second position, It is possible to reliably execute at a set timing the operation that enables the face material to be released by the closing mechanism and the unlocking of the face material by the locking mechanism, and the openable operation and the unlocking can be smoothly performed.
Furthermore, since the movable body can reciprocate in the direction along the frame, as in the case of the open / close arm of Patent Document 1 which is rotationally driven, the movable body, etc. It does not stand out. For this reason, the appearance and interior appearance of the fitting provided with the opening and closing device can be simply configured.
In addition, since the closing mechanism and the locking mechanism can be operated by the reciprocation of one moving body, it is only necessary to provide one drive device for driving the moving body. For this reason, compared with the case where a drive is provided in the closing mechanism and the locking mechanism, respectively, the cost can be reduced, and the opening and closing device can be made compact. Furthermore, in the case where a plurality of drive devices are provided, control of drive timing etc. is required in the control device that controls the drive of each drive device, and the control becomes complicated. Since it is only necessary, the control is simplified and the switchgear can be operated stably.
In addition, the locking mechanism should just be comprised so that unlocking of a face material is possible based on the return to the 1st position from the 3rd position of a mobile, and the following three structures from which a unlocking timing differs are included. It is
That is, the face material may be unlocked by the locking mechanism first, and then the face material may be released from the closed state (the face material may be opened) by the closing mechanism. That is, when the movable body is between the third position and the second position, the closing state of the face material by the closing mechanism is maintained. Therefore, after the face material is unlocked by configuring the locking mechanism to perform the unlocking operation based on the return movement while the movable body returns from the third position to the second position, The closed state can be released.
Alternatively, the face material may be unlocked by the locking mechanism after the face material is released from the closed state by the closing mechanism. That is, when the movable body is in the second position, the facing is in the closed state. The closing mechanism gradually releases the closed state when the movable body in the second position moves back toward the first position. Therefore, the closing mechanism is configured such that the shoji can be fully opened before the moving body reaches the first position, and the unlocking operation is performed when the moving body is returned toward the first position from the position where the shoji can be fully opened. By configuring the locking mechanism to be performed, it is possible to unlock the facing after releasing the closed state of the facing.
Furthermore, it may be configured to simultaneously unlock the face material by the locking mechanism and release the closed state of the face material by the closing mechanism. That is, by configuring the locking mechanism so as to perform the unlocking operation until the moving body in the second position moves back toward the first position to reach the position where full opening of the shoji is allowed. Unlocking of the facing and simultaneous release of the closing of the facing can be performed simultaneously.
In addition, only by switching the forward movement and the backward movement of the slider, it is possible to switch the contact of the contact member to the locking contact piece and the contact to the unlocking contact piece. Thereby, the linkage member can be moved in the locking direction and the unlocking direction, and locking and unlocking of the face member in the locking portion can be easily performed. Furthermore, by setting the connection position of the locking abutment and the unlocking abutment to the linkage bar, the switching timing of the closing state and the releasable state of the face material by the movement of the movable body, the locking of the locking portion and Since the switching timing of the unlocking can be set mechanically, it is possible to always stably perform the opening / closing operation of the facing and the locking / unlocking operation at the same timing.

  Moreover, the opening / closing device of the present invention includes a face material provided with an upper eyelid, a lower eyelid, left and right vertical eyelids and a panel, and a frame provided with an upper frame, a lower frame, and left and right vertical frames. An opening and closing device capable of opening and closing the facing in a fitting rotatably supported by a vertical frame about a horizontal axis, the closing mechanism capable of moving the facing to a closing position, and the face in the closing position And a locking mechanism capable of locking the material, wherein the closing mechanism can move forward from the first position to the third position via the second position along the frame and from the third position The movable body includes a movable body capable of returning to the first position via the second position, and a drive device for reciprocatingly driving the movable body, the movable body is provided on the vertical frame, and the locking mechanism is A linkage member abutting on the movable body, and interlockable with movement of the linkage member A lock portion, the linkage member is provided on the vertical weir, and the lock portion is provided on an upper lock portion provided on the upper frame and the upper weir, and the lower frame and the lower weir A lower locking portion, the upper locking portion includes a locking member provided on the upper collar, and a lock receiving member provided on the upper frame, and the lower locking portion includes the lower collar And a lock receiving member provided on the lower frame, wherein the lock member is connected to the linkage member, and is engaged with the lock receiving member based on the movement of the linkage member. While being capable of disengaging from the lock receiving member based on the reverse movement of the linkage member, the closing mechanism is configured to move from the first position to the second position of the movable body. Closing the facing on the basis of The locking mechanism is configured to be movable to a position, and the locking mechanism is configured to be able to lock the facing based on the forward movement of the movable body from the second position to the third position, and the closing mechanism is configured to move the movement. The face material can be released based on the second movement of the body from the second position to the first position, and the locking mechanism is the second movement of the movable body from the third position to the first position. And the face material can be unlocked.
  According to the present invention as described above, the closing mechanism and the locking mechanism can be interlocked with each other by a simple configuration in which the movable body is reciprocated.
  That is, since the movable body can move forward from the first position to the third position, the movement of the movable body from the first position to the second position and the movement of the movable body from the second position to the third position Can be done continuously. Therefore, the movement of the face material to the closing position by the closing mechanism, which is performed while the moving body moves from the first position to the second position, and the row while the moving body moves from the second position to the third position There is no need to control the timing of switching between the locking operation of the facing by the locking mechanism to be performed by the control device or the like by the control device etc., and only moving the moving body from the first position to the third position via the second position The movement of the face material to the closed position by the mechanism and the locking of the face material by the locking mechanism can be reliably performed at the set timing, and the switching from the closing movement to the locking can be smoothly performed.
  Further, in the movement (return movement) from the third position to the first position of the movable body, the movable body can be moved from the second position to the first position. For this reason, the moving operation which enables the face material to be released by the closing mechanism, which is performed while the movable body moves from the second position to the first position, and the line during the movement of the movable body from the third position to the first position It is not necessary to control the timing to execute the unlocking operation of the surface material by the locking mechanism to be performed by the control device etc., and only by moving the movable body from the third position to the first position via the second position, It is possible to reliably execute at a set timing the operation that enables the face material to be released by the closing mechanism and the unlocking of the face material by the locking mechanism, and the openable operation and the unlocking can be smoothly performed.
  Furthermore, since the movable body can reciprocate in the direction along the frame, as in the case of the open / close arm of Patent Document 1 which is rotationally driven, the movable body, etc. It does not stand out. For this reason, the appearance and interior appearance of the fitting provided with the opening and closing device can be simply configured.
  In addition, since the closing mechanism and the locking mechanism can be operated by the reciprocation of one moving body, it is only necessary to provide one drive device for driving the moving body. For this reason, compared with the case where a drive is provided in the closing mechanism and the locking mechanism, respectively, the cost can be reduced, and the opening and closing device can be made compact. Furthermore, in the case where a plurality of drive devices are provided, control of drive timing etc. is required in the control device that controls the drive of each drive device, and the control becomes complicated. Since it is only necessary, the control is simplified and the switchgear can be operated stably.
  In addition, the locking mechanism should just be comprised so that unlocking of a face material is possible based on the return to the 1st position from the 3rd position of a mobile, and the following three structures from which a unlocking timing differs are included. It is
  That is, the face material may be unlocked by the locking mechanism first, and then the face material may be released from the closed state (the face material may be opened) by the closing mechanism. That is, when the movable body is between the third position and the second position, the closing state of the face material by the closing mechanism is maintained. Therefore, after the face material is unlocked by configuring the locking mechanism to perform the unlocking operation based on the return movement while the movable body returns from the third position to the second position, The closed state can be released.
  Alternatively, the face material may be unlocked by the locking mechanism after the face material is released from the closed state by the closing mechanism. That is, when the movable body is in the second position, the facing is in the closed state. The closing mechanism gradually releases the closed state when the movable body in the second position moves back toward the first position. Therefore, the closing mechanism is configured such that the shoji can be fully opened before the moving body reaches the first position, and the unlocking operation is performed when the moving body is returned toward the first position from the position where the shoji can be fully opened. By configuring the locking mechanism to be performed, it is possible to unlock the facing after releasing the closed state of the facing.
  Furthermore, it may be configured to simultaneously unlock the face material by the locking mechanism and release the closed state of the face material by the closing mechanism. That is, by configuring the locking mechanism so as to perform the unlocking operation until the moving body in the second position moves back toward the first position to reach the position where full opening of the shoji is allowed. Unlocking of the facing and simultaneous release of the closing of the facing can be performed simultaneously.
  In addition, by moving the movable body provided on the vertical frame of the fitting configured as the horizontal axis rotary window along the vertical frame, the linkage member provided on the vertical rod is moved along the vertical rod. It can be done. Further, by the movement of the linkage member, the upper locking portion can be operated to engage the upper collar with the upper frame, and the lower locking portion can be operated to engage the lower collar with the lower frame. . By thus engaging the upper frame and the lower frame which are vertically spaced from the horizontal axis with the upper frame and the lower frame, a firm locking state of the horizontal axis rotation window can be realized.

The switchgear of the present invention, the unlocking abutment piece is rotatably supported on the frame or the surface material, as the movement of the front Machinery tablets direction rotation relative to the frame body or the surface material The link member is communicably connected to the linkage bar, and the unlocking contact piece is disposed on the movement locus of the contact member in the locked state of the face member, and in the unlocked state of the face member. It is preferable to be disposed out of the movement trajectory of
According to such a configuration, when the contact member positioned away from the locking contact piece moves forward than the unlocking contact piece, the contact member deviates from the movement locus of the contact member. Without coming into contact with the unlocking contact piece located there, passing through the unlocking contact piece and coming into contact with the locking contact piece. Therefore, during forward movement of the contact member, the unlocking contact piece is not rotated and the linkage member is not moved.
In addition, when the contact member positioned closer to the locking contact piece than the locking contact piece returns, the contact member is located on the movement locus of the contact member. Abuts on the contact piece. Therefore, when the contact member returns from the third position to the first position, the unlocking contact piece is rotated to move the linkage member to unlock the face material.
As described above, the forward movement of the contact member allows the unlocking contact piece to pass through, while the backward movement of the contact member can cause the unlocking contact piece to contact. For this reason, while being able to perform desired unlocking operation, the space | interval of the contact part for locking and the contact part for unlocking can be narrowed, and it can be configured, and the miniaturization of a linkage member can be achieved.
Furthermore, since the rotatable unlocking contact piece can be removed from the movement trajectory of the contact member, the unlocking contact piece is on one side of the locking contact rather than the axial center (rotational axis) of the face material. It can be arranged.
For example, in an opening and closing device in which the unlocking contact piece is disposed at a position farther from the locking contact piece than the axis of the face material, the contact member is the unlocking contact piece in the backward movement of the movable body. Before coming into contact and releasing the lock, it is positioned further from the locking contact piece than the axis of the face material, and the forced closing state of the face material due to the contact of the contact member is released. For this reason, the timing which permits the open movement of a face material after unlocking can not be adjusted as desired.
In the opening / closing device of the present invention as described above, in comparison with such an opening / closing device, in the return movement of the contact member, after the contact member contacts and comes into contact with the unlocking contact piece, It is positioned further from the locking contact piece than the locking contact piece, and cancels the forced closing state of the face material due to the contact of the contact member. For this reason, even after unlocking, it is possible to adjust the timing at which the opening movement of the face material is permitted.

In the opening / closing device according to the present invention, the contact member includes a pressing roller for pressing the surface material, and a shaft member for supporting the pressing roller, and the shaft member moves from the second position to the third position. It is preferable to be able to abut against the locking abutment piece in the forward movement, and to be abuttable against the unlocking abutment piece during the return from the third position to the first position. .
According to such a configuration, while the face material can be smoothly pressed by the pressing roller, the shaft member can be brought into contact with the locking abutment piece or the unlocking abutment piece without interfering with the pressing roller. it can. Therefore, the closing movement and the locking of the face material can be switched smoothly.

In the opening / closing device according to the present invention, in the case where a plurality of the surface members are provided in parallel and the frame includes a frame member positioned between adjacent surface members among the plurality of surface members, the movable body is the frame Reciprocably mounted on a member, the pressing rollers are provided as a pair on both sides in the direction in which the facings are arranged, and one pressing roller is capable of closing and guiding one of the facing members adjacent to each other. Preferably, the other pressing roller is disposed so as to be capable of closing and guiding the other by pressing the other of the face materials adjacent to each other.
According to such a configuration, by pressing the surface material with the pair of pressure rollers provided on both sides in the direction in which the surface material is arranged, the shaft member and the slider that support the pair of pressure rollers move without tilting Body position and movement can be stabilized.

In the opening / closing device according to the present invention, when a plurality of the surface members are provided in parallel, the plurality of moving bodies are provided at positions corresponding to the plurality of surface members, and the driving device includes one driving source, It is preferable to provide a transmission path for transmitting the driving force from one driving source to the plurality of moving bodies.
According to such a configuration, it is possible to operate both the closing mechanism and the locking mechanism in a timely manner only by transmitting the driving force from one drive source to the moving body.

In the opening / closing device according to the present invention, the first position where the movable body is disposed is a position where the face material can be released, and the closing mechanism is configured to move the movable body from the third position to the second position. And can be moved back to a fourth position via the first position, and can be moved forward to the third position from the fourth position via the first position and the second position, The surface member is provided with a restriction piece positioned on the movement trajectory of the movable member, and the movable member is in contact with the restriction member in a state of being disposed at the fourth position to close the movement of the surface member It is preferable to regulate
According to such a configuration, when the movable body is disposed at the fourth position and abuts against the restricting piece, the closing movement of the face material can be restricted to be in the fixed open state. Thereby, the face material can be exhausted without being closed by the wind pressure.
In addition, even when the facing is windy and is closer to the closed position than the fully open position, the moving object moves from the first position toward the fourth position, whereby the restriction placed on the movement trajectory of the moving object It comes in contact with the piece and the face material can be forcibly moved open.
Here, the first position where the face material can be opened may be a position where the face material can be released to the fully open position, or a position before the fully open position (on the closed position side) It may be a position where it can be opened up to the position).

A fitting according to the present invention includes a frame, a face material, and the above-described opening and closing device according to the present invention capable of opening and closing the face material.
With such a fitting, the effects of the respective fittings described above can be exhibited, and the open / close state and the locking state suitable for the fitting can be maintained well.

  According to the present invention, it is possible to smoothly perform the closing movement, the locking, and the locking of the face material with a simple configuration.

That is, it is the central position of the height dimension of the visible part of the panel 25.
Further, the position in the prospective direction of the center of gravity 26 of the shoji 2A is set between the panels 25.

  The shoji 2B is arranged in parallel to the shoji 2A in the left-right direction, and is configured in the same manner as the shoji 2A. Therefore, as for the shoji 2B, the same reference numerals as those of the construction of the shoji 2A are appropriately attached to the drawing, and the detailed description thereof is omitted.

  The window frame 3 includes an upper frame 31, a lower frame 32, left and right vertical frames 33, 34, and a cross member 35 (vertical frame) as a frame member disposed between the vertical frames 33, 34. There is. The upper frame 31, the lower frame 32, and the left and right vertical frames 33, 34 are formed of an extruded material made of aluminum. The cross section 35 is disposed between the upper frame 31 and the lower frame 32 at an intermediate position in the left-right direction of the horizontal axis rotation window 1. For this reason, the gutter 35 is located between the shoji 2A, 2B adjacent to each other in the left-right direction. The upper frame 31, the lower frame 32, and the left and right vertical frames 33, 34 may be made of resin.

  To the vertical frames 33, 34 are attached door-stop members 36 with which the shoji 2A, 2B in the open position shown in FIG. 6 abut. Therefore, when the shojis 2A and 2B are rotated in the opening direction, they rotate only to a position in contact with the door stop member 36.

As shown in FIGS. 3 and 9, the gutter 35 includes a gutter main body 351 having a substantially rectangular shape, a concave portion 352 formed on the outdoor looking portion of the gutter main body 351, and a pair of gutter main bodies 351. It has the outdoor side extension part 353 and the indoor side extension part 354 which extended in the finding direction from the prospective piece part toward the shoji 2. An elastic draining material 353 A is provided in the outdoor-side extension 353, and an airtight material 345 is provided in the indoor-side extension 354.
When the shoji 2 is in the fully closed position, as shown in FIG. 9, the drainage material 353A of the outdoor extension 353 is in contact with the drainage material 245 of the longitudinal weir 24, and the airtight material 345 is the chamber of the longitudinal weir 24. It is in contact with the inner finding piece 244.
In addition, FIG. 9 has shown the flat cross section of the upper part rather than the axial center 37 of the shoji 2. As shown in FIG. The upper portion is configured to be openly movable toward the indoor side. Contrary to this upper part, the lower part than the axial center 37 of the shoji 2 is configured to be openly movable to the outdoor side. Specifically, in the lower portion, the indoor side locating piece portion 244 and the indoor side extending portion 354 are disposed to face each other in the left-right direction, the draining material 245 is provided to the indoor side locating piece portion 244, and the draining material 353A is It is provided in the indoor side extension. The outdoor side finding piece portion 241 is located on the outdoor side relative to the outdoor side extending portion 353, and the airtight material 345 is provided on the outdoor side finding piece portion 241.

The window frame 3A is configured by a vertical frame 33 on the right side, an upper frame 31 and a lower frame 32, and a gutter 35 when viewed from the indoor side. Vertical frame 33 and gutter 35 which constitute window frame 3A rotatably support vertical bars 23 and 24 of shoji 2A about a horizontal axis (not shown).
The axis 37 of the horizontal axis is at the same height position as the position of the center of gravity 26 of the shoji 2A, and is set at a position where the position in the prospective direction with respect to the center of gravity 26 is shifted to the indoor side.

The left vertical frame 34, the upper frame 31 and the lower frame 32, and the cross 35 as viewed from the indoor side constitute a left window frame 3 </ b> B. Vertical frame 34 and gutter 35 which constitute window frame 3B rotatably support vertical bars 23 and 24 of shoji 2B centering on a horizontal axis (not shown).
The axis 37 of the horizontal axis is at the same height position as the position of the center of gravity 26 of the shoji 2B, and is set at a position where the position in the prospective direction with respect to the center of gravity 26 is shifted to the indoor side.
In addition, it is good for the horizontal axis mentioned above to be supported by the window frame 3 so that the position of indoor and outdoor direction can be adjusted.

  When the center of gravity 26 is located on the indoor side with respect to the axial center 37 of the horizontal axis, a rotational moment N in the direction in which the upper end moves to the indoor side is generated in the shoji 2. As the distance between the axial center 37 and the center of gravity 26 increases, the rotational moment also increases. Therefore, in the present embodiment, the axial center 37 is set at a position that satisfies the following conditions. That is, the predetermined distance between the axial center 37 and the center of gravity 26 is set based on the following conditions.

[Condition of the position of the rotational axis of shoji
(1) Fully open state when there is no wind When wind pressure is not applied to the shoji 2 of the horizontal axis rotation window 1 during no wind, the center of gravity 26 is eccentric to the indoor side with respect to the axial center 37 of the horizontal axis. In the case of the shoji 2, the rotational moment N moves towards the inside of the room, and the upper end moves toward the indoor side. The positional relationship (predetermined distance) between the center of gravity 26 and the axial center 37 is set such that the turning moment N rotates at least the position where the shoji 2 abuts on the door contact member 36. In the present embodiment, the shoji 2 is set to rotate 45 degrees from the closed position to a position in contact with the door stop member 36.
Accordingly, when there is no wind, the shoji 2 of the horizontal axis rotation window 1 automatically rotates to the fully open position shown in FIG. 6 to open the horizontal axis rotation window 1. For this reason, the horizontal axis rotation window 1 can be brought into a natural ventilation state.
Although the rotation angle from the closing position to the position at which the shoji 2 abuts on the door stop member 36 has been described as 45 degrees, this rotation angle can be set arbitrarily, for example, 30 degrees, 60 degrees, etc. It is.

(2) If the wind speed is less than the threshold, maintain the fully open state. When the breeze to weak wind blows, that is, when the wind pressure applied to the shoji 2 is less than the set threshold, the shoji 2 rotates in the closing direction. Power is added. In this case, the rotational moment N for rotating the shoji 2 in the opening direction is larger than the rotation moment for rotating the shoji 2 in the closing direction by wind pressure, due to the eccentricity of the axial center 37 and the center of gravity 26 of the horizontal axis. The distance between the axial center 37 and the center of gravity 26 is set to a predetermined distance.

(3) If the wind speed is higher than the threshold, it turns in the closing direction of the shoji. When the wind from medium to strong wind blows and the wind pressure applied to the shoji 2 becomes higher than the set threshold, the wind closes the shoji 2 by the wind pressure. The distance between the axial center 37 and the gravity center 26 is set such that the rotational moment to rotate is larger than the rotational moment N to rotate the shoji 2 in the opening direction by the eccentricity of the axis 37 of the horizontal axis and the gravity center 26 outward of the room. The distance is set.
(3-1) In the case of positive pressure When wind blows from the outdoor side toward the indoor side toward the wall surface where the horizontal axis rotation window 1 (joint window) is attached in the building, A positive pressure from the outdoor side toward the indoor side is applied to a portion below the axis 37 of the horizontal axis. Therefore, the lower half of the shoji 2 is pushed toward the indoor side and rotates in the closing direction. The positive pressure applied to the shoji 2 increases as the wind pressure increases, so the opening angle of the shoji 2 decreases as the wind speed increases. And if the wind more than the predetermined | prescribed 2nd threshold larger than the said threshold blows, the shoji 2 will close as shown in FIG. Although a pressing roller 515 described later, which is indicated by a two-dot chain line in FIG. 5, is illustrated at an upper position with respect to the axial center 37 of the horizontal axis, it is positioned below the axial center 37 of the horizontal axis in a natural ventilation state.
(3-2) In the case of negative pressure Similarly, when the wall surface of the building on which the horizontal axis rotation window 1 (joint window) is attached is the downwind side, the wind flowing from the indoor side to the outdoor side Blows and negative pressure is applied. In this case, a negative pressure directed from the indoor side to the outdoor side is applied to the upper half of the axis 37 of the horizontal axis of the shoji 2 located on the windward side. Therefore, the upper half of the shoji 2 is pushed toward the outdoor side and rotates in the closing direction. The negative pressure applied to the shoji 2 also increases as the wind speed increases, so the opening angle of the shoji 2 decreases as the wind speed increases. And if the wind more than the predetermined | prescribed 2nd threshold larger than the said threshold blows, the shoji 2 will close as shown in FIG.

The contact surface of the pressure roller 515 contacts the indoor-side finding surface of the longitudinal bar 24 of the shoji 2A in the closed position. When the pressing roller 515 is positioned lower than the axis 37 of the horizontal axis, the shoji 2A is separated from the pressing roller 515 by the opening movement.
Further, the contact surface of the pressing roller 515 contacts the finding surface of the longitudinal bar 24 of the shoji 2A in the open position by the upward movement of the pressing roller 515, and is disposed so as to be able to press the finding surface.

The contact member 512B is juxtaposed to the contact member 512A in the left-right direction via the cross member 35. For this reason, the pressing roller 515 is provided as a pair on both sides in the arrangement direction of the shoji 2A, 2B.

And the unlocking contact piece 715. The locking abutment piece 712 and the unlocking abutment piece 715 are shown in FIG. 11 to the extent that the unlocking abutment piece 715 which rotates in the locking operation abuts against the shaft member 514 and does not inhibit the locking operation. Thus, they are arranged at predetermined intervals in the vertical direction. The locking abutment piece 712 is located above the unlocking abutment piece 715.

  The linkage bar 711 is movably engaged with the guide groove forming portion 243C of the vertical weir 24 in the vertical direction, and is disposed in the guide groove formed by the guide groove forming portion 243C.

The outdoor end 715 A is rotatably attached to the shaft pin 713. Therefore, the unlocking contact piece 715 is supported by the vertical weir 24 so as to be rotatable about the rotation axis of the shaft pin 713.
An axial pin 714 is rotatably disposed in the long hole 715C. Therefore, the unlocking contact piece 715 is allowed to rotate about the rotation axis of the shaft pin 713, and is connected to the linkage bar 711 so that the rotation can be transmitted as movement in the vertical direction. It is movable relative to the linkage bar 711 along the radial direction centering on the rotation axis of the shaft pin 713 and is connected to the linkage bar 711 rotatably around the rotation axis of the shaft pin 713 There is.

Among the portions exposed on the indoor side of the unlocking contact piece 715, the edge portion located on the locking contact piece 712 side is formed to be curved as shown in FIGS.
In the locked state shown in FIG. 11, the inclination angle of the unlocking contact piece 715 with respect to the horizontal plane is set small. Therefore, the portion exposed to the indoor side of the unlocking contact piece 715 is disposed on the movement trajectory of the shaft member 514.
Further, in the unlocked state shown in FIG. 12, the inclination angle of the unlocking contact piece 715 with respect to the horizontal plane is set large. Therefore, the portion exposed on the indoor side of the unlocking contact piece 715 is spaced apart from the shaft member 514 in the indoor and outdoor directions, and is disposed on the outdoor side from the movement trajectory of the shaft member 514.

The locking portion 72 has a lower locking portion 73 and an upper locking portion 74, as shown in FIG.
The lower locking portion 73 includes a locking member 731 provided to the lower rod 22 and two lock receiving members 732 provided to the lower frame 32.

One shaft pin 741B is located on the side of the vertical shaft 23, and the other shaft pin 741B is located on the vertical shaft 24.
The movable member 741A is formed to extend along the upper collar 21 and is connected to the upper end of the linkage bar 711 via the flexible joint 743 at the end on the side of the gutter 35.
When the shoji 2A is in the fully closed position, the two lock receiving members 742 are disposed on the indoor side of the two axial pins 741B. One lock receiving member 742 is located on the vertical frame 33 side, and the other lock receiving member 732 is located on the side 35.
As shown in FIG. 13, the lock receiving member 742 is configured as an abutting surface in which the outdoor side surface 742A can abut on the shaft pin 741B.

Such a locking portion 72 is capable of moving the locking members 731 and 741 mechanically in synchronization in the left and right direction based on the upward movement of the linkage member 71 (the movement in the locking direction). The pins 731 B and 741 B can be engaged with the lock receiving members 732 and 742.
In addition, the locking portion 72 is capable of moving the locking members 731 and 741 in the direction opposite to the above-mentioned direction in mechanical synchronization based on the downward movement of the linkage member 71 (the movement in the unlocking direction). By this movement, the engagement between the shaft pins 731B and 741B and the lock receiving members 732 and 742 can be released. FIG. 14 shows the shaft pin 731 B and the lock receiving member 732 in the disengaged state.

  The locking mechanism 7B is disposed to face the locking mechanism 7A in the left-right direction, and is configured substantially the same as the locking mechanism 7A. Therefore, about each composition of locking mechanism 7B, the same numerals as each composition of locking mechanism 7A are suitably attached to a figure, and the detailed explanation is omitted.

Operation of First Embodiment
Hereinafter, the operation of the horizontal axis rotation window 1 according to the present embodiment will be described. In addition, since the horizontal axis rotation windows 1A and 1B operate in the same manner as each other, they will be collectively described.
In the horizontal axis rotation window 1 according to the present embodiment, when the movable body 51 is moved downward by the driving device 52 and the pressing roller 515 is positioned lower than the axial center 37 of the horizontal axis as shown in FIG. When the forced closing by the closing mechanism 5 is released, the free movement of the shoji 2A, 2B is permitted. For this reason, the horizontal axis rotation window 1 is in a natural ventilation state. And, the contact member 512 is lower than the axial center 37 of the horizontal axis, and the first position where the shoji 2 can move to the fully open position (a position where the contact member 512 shown by the two-dot chain line in FIG. Located in).
When the horizontal axis rotation window 1 is in the natural ventilation state, the locking mechanism 7 is in the unlocked state shown in FIGS. 12 and 14, and the shaft member 514 is lower than the unlocking contact piece 715 and the unlocking The unlocking contact piece 715 is positioned away from the movement locus of the shaft member 514, being spaced apart from the locking contact piece 712 more than the locking contact piece 715.

[Closing and locking action]
Hereinafter, the closing and locking operation of the horizontal axis rotation window 1 in the natural ventilation state described above by the opening and closing device 10 will be described.
First, the moving mechanism 51 is moved upward (forward movement) from the first position, which is the backward movement end, to the second position by the closing mechanism 5.
Specifically, the rotating shaft 552 is rotated by the driving force from the drive source 54, and the rotation is transmitted to the rotating shaft 553 via the worm gear mechanism 554, thereby being connected to the rotating shaft 553. The ball screw shaft 555 is rotated.
The rotation of the ball screw shaft 555 moves the slider 511 upward along the cross rail 35 while being guided by the guide rail 53.
Due to the upward movement of the slider 511, the pressing roller 515 moves upward along the vertical 35, and the contact surface of the pressing roller 515 in the circumferential direction is the finding surface of the indoor looking piece portion 244 of the open longitudinal rod 24. Contact After contact between the pressing roller 515 and the vertical rod 24, the upward movement of the pressing roller 515 causes the portion of the vertical rod 24 located above the axis 37 of the horizontal axis by the pressing roller 515 to move outward. And force the shoji 2 to move in the closing direction.
The pair of pressure rollers 515 move in synchronization with each other. For this reason, the upward movement of the pair of pressing rollers 515 simultaneously causes the shojis 2A and 2B to forcibly close.

In the upward movement of the pressing roller 515, the shaft member 514 does not contact the unlocking contact piece 715 located away from the movement trajectory of the shaft member 514, and the indoor side of the unlocking contact piece 715. (See the shaft member 514 shown by a solid line in FIG. 12).
When the contact member 512 moved upward in this manner reaches the second position, the shoji 2 is completely closed. When the contact member 512 having reached the second position further moves upward, the shaft member 514 reaches the locking start position indicated by a two-dot chain line in FIG. 12 and contacts the contact portion 712B of the locking contact piece 712. Then, by the further upward movement of the moving body 51, the shaft contact member 514 pushes up the locking contact piece 712, moves the linkage bar 711 upward, and moves the locking member 731 of the lower locking portion 73 in the left-right direction. As shown in FIG. 13, the shaft pin 731B is brought into contact with and engaged with the indoor side surface 732A of the lock receiving member 732.
On the other hand, in the upper locking portion 74 as well, by the upward movement of the moving body 51 described above, the lower locking portion 73 operates similarly to engage the shaft pin 741 B and the lock receiving member 742. At the time of the engagement, the shaft member 514 is located at the third position (locked completed position) which is the forward end shown in FIG. 11 located above the second position. In this manner, locking is performed by the locking mechanism 7.
Note that the unlocking contact piece 715 rotates while being pulled upward by the shaft pin 714 by the upward movement of the linkage bar 711, and this rotation further extends the indoor end 715B toward the indoor side. , And is located on the movement trajectory of the shaft member 514.
Further, since the shaft pins 731B and 741B are held by the indoor side surface 732A and the outdoor side surface 742A, even if the shaft member 514 is separated from the locking contact piece 712, the locking contact piece 715 is pushed down by the shaft member 514. The linkage bar 711 holds its position unless it can. Therefore, the locking state of the shoji 2 can be stabilized.
In this way, the horizontal axis rotation window 1 is closed and locked.

[Locking and opening action]
Next, the unlocking and opening operation of the horizontal axis rotation window 1 in the locking and fully closed state described above by the opening and closing device 10 will be described.
First, the movable body 51 is moved downward (return) from the third position by the closing mechanism 5.
Specifically, by transmitting the driving force from the drive source 54 to the movable body 51 via the transmission mechanism 55, the movable body 51 is moved downward along the crosshairs 35. By this downward movement, the slider 511 is moved downward (return movement), and the shaft member 514 is moved downward from the third position toward the second position.
In this downward movement, the shaft member 514 abuts on the unlocking contact piece 715. Then, by the further downward movement of the movable body 51, the unlocking contact piece 715 is pushed down by the shaft member 514, the unlocking contact piece 715 is rotated downward, and the linkage bar 711 is moved downward in conjunction. The downward movement of the linkage bar 711 moves the lock members 731 and 741 in the left and right direction to separate the shaft pins 731 B and 741 B from the lock receiving members 732 and 742. As a result, as shown in the phantom line in FIG. 13 and in FIG. 14, the engagement between the lock members 731 and 741 and the lock receiving members 732 and 742 is released. In this manner, the locking mechanism 7 performs the unlocking. When the engagement is released, the shaft member 514 is located at the unlocking completion position shown by a solid line in FIG. 12 which can pass the unlocking contact piece 715.
Subsequently, by the downward movement of the movable body 51, the pressing roller 515 is positioned below the axial center 37 of the horizontal axis, and the opening movement of the shoji 2 is permitted. Then, the shoji 2 moves open based on its own weight, and is located at the fully open position to be in a natural ventilation state. When the contact member 512 reaches the first position due to the downward movement of the movable body 51, the shoji 2 can move to the fully open position as described above.
Thus, the horizontal axis rotation window 1 is unlocked and released.

[Effect of First Embodiment]
(1) It is possible to interlock the closing movement of the shoji 2 by the closing mechanism 5 and the locking and unlocking by the locking mechanism 7 with a simple configuration in which the moving body 51 is reciprocated.
That is, since the movable body 51 can reciprocate from the first position to the third position, the movement of the movable body 51 from the first position to the second position and the movement of the movable body 51 from the second position to the third position And can be done continuously. For this reason, the moving operation from the closing mechanism 5 to the closing position of the shoji 2 performed while the moving body 51 moves from the first position to the second position, and the moving body 51 moves from the second position to the third position The switching with the locking operation of the shoji 2 by the locking mechanism 7 performed in the meantime can be reliably performed at the set timing.
Further, in the movement of the movable body 51 from the third position to the first position, the movable body 51 can be moved from the second position to the first position. For this reason, the moving operation for opening the shoji 2 by the closing mechanism 5 which is performed while the moving body 51 moves from the second position to the first position, and the moving body 51 moves from the third position to the first position The timing of executing the unlocking operation of the shoji 2 by the locking mechanism 7 performed in the meantime can be reliably performed at the set timing.
Furthermore, since the movable body 51 is provided so as to be capable of reciprocating in the vertical direction along the gutter 35, the movable body 51 and the like protrude inside the horizontal axis rotation window 1 and the like when opening and closing the shoji 2 or locking. There is nothing to do. For this reason, the appearance and introspection of the horizontal axis rotation window 1 can be simply configured.
In addition, since the closing mechanism 5 and the locking mechanism 7 can be operated by the movement of one moving body 51, it is only necessary to provide one drive device 52 for driving the moving body 51. For this reason, compared with the case where a drive is provided in the closing mechanism 5 and the locking mechanism 7, respectively, the cost can be reduced, and the opening / closing device 10 can be made compact. Furthermore, in the case where a plurality of drive devices are provided, control of drive timing or the like is required in the control device that controls the drive of each drive device, and the control becomes complicated. Since it is only necessary to reciprocate, the control is simplified and the switching device 10 can be operated stably.
(2) The contact of the contact member 512 with the locking contact piece 712 and the contact with the unlocking contact piece 715 can be switched only by switching the forward and backward movements of the slider 511 . Thereby, the linkage member 71 can be moved in the locking direction and the unlocking direction, and the locking and unlocking of the shoji 2 in the locking portion 72 can be easily performed. Furthermore, by setting the connection position of the locking abutment piece 712 and the unlocking abutment piece 715 with respect to the linkage bar 711, the switching timing of the closing state and the releasable state of the shutter 2 by the movement of the moving body 51, and locking Since the switching timing of the locking and unlocking of the part 72 can be set mechanically, the opening / closing operation and the locking / unlocking operation of the shoji 2 can always be stably performed at the same timing.

(3) When the contact member 512 located farther from the locking contact piece 712 than the unlocking contact piece 715 moves upward, the contact member 512 is connected to the side 35 of the contact member 512. The lock contact piece 715 passes through the unlocking contact piece 715 without coming into contact with the unlocking contact piece 715 located out of the movement path along the path. Therefore, when the contact member 512 is moved upward, the unlocking contact piece 715 is not rotated and the linkage member 71 is not moved.
When the contact member 512 located closer to the locking contact piece 712 than the unlocking contact piece 715 moves downward, the contact member 512 is positioned on the movement locus of the contact member 512. It abuts against the unlocking contact piece 715. Therefore, when the contact member 512 moves downward from the third position to the first position, the unlocking contact piece 715 is rotated to move the linkage member 71, thereby unlocking the shoji 2.
Thus, the upward movement of the contact member 512 allows the unlocking contact piece 715 to pass through, while the downward movement of the contact member 512 causes the unlocking contact piece 715 to abut. Therefore, a desired unlocking operation can be performed, and the gap between the locking abutment piece 712 and the unlocking abutment piece 715 can be narrowed, and the linkage member 71 can be made compact.
Furthermore, even after unlocking, it is possible to adjust the timing at which the release of the shoji 2 is allowed, for example, by gradually moving the pressing roller 515 downward from the axial center 37, the releaseable angle of the shoji 2 can be adjusted. Can be gradually increased.
(4) While the shoji 2 can be pressed smoothly by the pressing roller 515, the shaft member 514 can be brought into contact with the locking abutment piece 712 or the unlocking abutment piece 715 without interference with the pressing roller 515 it can. Therefore, the closing movement and locking of the shoji 2 can be switched smoothly.

(5) By pressing the shoji 2 by the pair of pressing rollers 515 provided on both sides in the juxtaposition direction of the shoji 2, the shaft member 514 supporting the pair of pressing rollers 515 and the slider 511 do not tilt, and the moving body 51 position and movement can be stabilized.
(6) Only by transmitting the driving force from one drive source 54 to the movable body 51, both the closing mechanism 5 and the locking mechanism 7 can be operated in a timely manner.
Further, since there is no separate drive source 54 for the closing mechanism 5 and the locking mechanism 7, the configuration of the horizontal axis rotation window can be simplified.
(7) Reciprocating the moving body 51 provided on the weir 35 along the weir 35 to move the linkage member 71 provided on the weirs 23 and 24 along the weirs 23 and 24 Can. Further, by the movement of the linkage member 71, the lower locking portion 73 is operated to engage the lower collar 22 with the lower frame 32, and the upper locking portion 74 is operated to engage the upper collar 21 with the upper frame 31. It can be done. As described above, by engaging the upper frame 21 and the lower frame 22 which are vertically spaced from the horizontal axis with the upper frame 31 and the lower frame 32, a firm locking state of the horizontal axis rotation window 1 can be realized.

Configuration of Second Embodiment
Hereinafter, a second embodiment of the present invention will be described based on the drawings.
In FIGS. 15-17, the horizontal axis rotation window 100 which is a fixture according to the second embodiment is attached to the frame of a building, and the horizontal axis rotation windows 100A and 100B are two continuous windows arranged on the left and right. It is configured as a natural ventilation window that opens and closes naturally to ventilate and exhaust air.

The horizontal axis rotation window 100 is configured to include a shoji 2 (2A, 2B), a window frame 3 (3A, 3B), and an opening / closing device 10A capable of opening and closing the shoji 2 with respect to the window frame 3.
When the locking with the window frame 3 is released (unlocked), the shoji 2 moves from the closed position shown in FIG. 17 to the open position as shown in FIG. 18 based on its own weight and opens to the open position shown in FIG. ) To stand still. In addition, the lower part of the shaft 37 of the shoji 2 receives a wind from the outdoor side toward the indoor side, or the upper part of the shaft 2 of the shoji 2 receives the wind from the indoor side to the outdoor side. Move closed. The shoji 2 shown by a solid line in FIG. 18 is in the fully open position.

The opening / closing device 10A has the same configuration as the opening / closing device 10 in the first embodiment, and performs the opening / closing operation, the locking operation, and the unlocking operation as described above.
The movable body 51 of the opening / closing device 10A is configured to be capable of returning to the fourth position below the first position described above, and a restriction piece described later in which the pressing roller 515 is described in the state where the movable body 51 is at the fourth position. Abuts on 101. The third position is the position of the movable body 51 shown in FIG. 17, the first position is the position of the movable body 51 shown in FIG. 18, and the fourth position is the position of the movable body shown in FIG. is there. In the present embodiment, the fourth position is the return end position.

The opening / closing device 10A further includes a restriction piece 101 (101A, 101B) for restricting the closing movement of the shoji 2 in the open position shown in FIG.
The restriction piece 101 is provided so as to project from the vertical weir 24 of the shoji 2 to the indoor side. The tip of the restriction piece 101 is raised obliquely upward. Further, at the front end portion of the restriction piece 101, an abutting surface 102 is formed along the horizontal direction with the shoji 2 in the fully open position. The contact surface 102 is positioned on the movement locus of the pressing roller 515 so as to abut the pressing roller 515 in a state where the shoji 2 is in the fully open position and the movable body 51 is in the fourth position.
Moreover, the part by the side of a proximal end rather than the front-end | tip part of the control piece 101 is comprised so that arrangement | positioning is possible along a horizontal direction in the state which the shoji 2 exists in a closed position.
Furthermore, the restricting piece 101 is positioned lower than the pressing roller 515 in a state where the shoji 2 is in the closed position and the movable body 51 is in the first position.

[Operation of Second Embodiment]
The opening / closing operation and the locking / unlocking operation of the opening / closing device 10A are the same as those of the opening / closing device 10 of the first embodiment, and thus the description of these operations is omitted.
In the state where the movable body 51 is disposed at the first position shown in FIG. 18, the shoji 2 stops at the fully open position when there is no wind, and the wind from the outdoor side to the indoor side or the wind from the indoor side to the outdoor side blows Move closed to. Here, the restricting piece 101 does not abut on the pressing roller 515 of the moving body 51 at the first position even if the shoji 2 moves in the closing direction. When the movable body 51 is stopped between the first position and the fourth position, the restricting piece 101 abuts against the pressing roller 515 when the shoji 2 moves from the fully open position to the closing direction, so the fully closed state Instead, the closing movement of the shoji 2 from the fully open position can be adjusted.
Further, even when the shoji 2 receives the wind and is closer to the closed position than the fully open position (when not in the fully open position), the pressing roller 515 is restricted by moving the movable body 51 toward the fourth position. And the shoji 2 can be forcibly opened and moved. In addition, even when the shoji 2 receives the wind and is in the closed position, similarly, the moving body 51 is moved toward the fourth position and brought into contact with the restriction piece 101 so that the shoji 2 can be forcibly opened and moved. is there.

  When the movable body 51 is disposed at the fourth position in a state where the shoji 2 is in the fully open position, the pressing roller 515 is in contact with the contact surface 102 of the restriction piece 101. As a result, the closing movement of the shoji 2 is restricted, and the state in which the shoji 2 is in the fully open position is forcibly maintained in the fixed open state, and the exhaust can be performed. This exhaust gas is used, for example, for smoke exhaust at the time of fire.

[Effect according to the second embodiment]
(1) The horizontal axis rotation window 100 according to the second embodiment can exert the same function and effect as the horizontal axis rotation window 1 according to the first embodiment.
(2) The movable body 51 moves downward to the fourth position and the pressing roller 515 abuts on the contact surface 102 of the regulating piece 101, whereby the closing movement of the shoji 2 in the fully open position can be regulated. Thereby, the open state can be reliably maintained and the exhaust can be exhausted without the shoji 2 being closed by the wind pressure.

It is not limited to the above, and it may be a hole through which the axial pin 713 can pass. Therefore, for example, the hole through which the shaft pin 713 passes may be formed by holes of various shapes such as a circular hole, a rectangular hole and the like which are not formed to extend in the vertical direction.

  In the first embodiment, the unlocking contact piece 715 is provided with the long hole 715C in which the shaft pin 714 is inserted, but this configuration may be omitted. When the long hole 715C is not provided, the lower edge of the unlocking contact piece 715 located opposite to the locking contact piece 712 may be supported by the shaft pin 714. Also, a notch may be formed in the contact portion of the lower edge of the unlocking contact piece 715 with the shaft pin 714.

  In the first embodiment, the unlocking contact piece 715 is rotatably attached to the longitudinal rod 24 via the shaft pin 713, but is not limited thereto. For example, a link (not shown) on the longitudinal rod 24 It may be attached via a mechanism, and may be configured to cause forward / backward movement or swing in the indoor / outdoor direction by upward movement of the linkage bar 711 or downward movement of the shaft member 514.

  In the first embodiment, the unlocking contact piece 715 is provided rotatably about the rotation axis of the shaft pin 713, but the invention is not limited to this. It may be rotatably provided. In this case, for example, the unlocking contact piece 715 is configured to include a circular hole (not shown) through which the shaft pin 714 can be inserted, and a long hole (not shown) in which the shaft pin 713 is disposed. Even with such a locking abutment piece 715, when the shoji 2 is in the locked state, the tip end portion exposed to the indoor side of the locking abutment piece 715 can be disposed on the movement trajectory of the shaft member 514. In addition, in the unlocked state of the shoji 2, it can be disposed off the outdoor side from the movement trajectory of the shaft member 514.

  In the said 1st Embodiment, although the linkage member 71 is provided in the vertical weir 24 of the shoji 2, it may be provided, for example, on the side 35 of the window frame 3. As shown in FIG. In this case, the lock members 731 and 741 are provided on the upper frame 31 and the lower frame 32, respectively, and the lock receiving members 732 and 742 are provided on the upper frame 21 and the lower frame 22, respectively. Further, the outdoor end portion 715 A of the unlocking contact piece 715 is rotatably supported by the cross rail 35.

In the first embodiment, the shoji 2 is configured to be able to open and move by moving the upper collar 21 to the indoor side and moving the lower ridge 22 to the outdoor side based on its own weight, and the locking abutment piece 712 is The unlocking abutment piece 715 is disposed downward, the forward movement of the movable body 51 is upward movement, and the backward movement of the movable body 51 is downward movement.
Contrary to such a configuration, the shoji 2 may be configured to be able to open and move by moving the upper iron 21 to the outdoor side and moving the lower iron 22 to the indoor side based on its own weight. Then, the locking abutment piece 712 may be disposed downward, the unlocking abutment piece 715 may be disposed upward, the forward movement of the movable body 51 may be downward movement, and the backward movement of the movable body 51 may be upward movement. .
In this case, the shoji 2 is forcibly closed and moved by the downward movement of the movable body 51, and the locking mechanism 7 performs the locking operation by the downward movement of the linkage member 71. In addition, the shoji 2 is unlocked by the upward movement of the moving body 51, and the forced closing state is released by the further downward movement.

  In the first embodiment, the driving device 52 is configured to move the movable body 51 by the rotation of the ball screw shaft 555, but the invention is not limited thereto. For example, the movable body 51 may be a string-like body. It may be configured to be movable in the reciprocating direction by connecting and pulling the string-like body.

  In the said 1st Embodiment, although the guide rail 53 is provided in the gutter 35, it is not limited to this, For example, you may be provided in each of the vertical frames 33 and 34 on either side.

Further, in the second embodiment, when the movable body 51 is in the fourth position, the pressing roller 515 abuts against the restriction piece 101 and the shoji 2 abuts on the door stop member 36. Both the movement and the closing movement are in a restricted state, but not limited thereto. For example, in a state where the moving body 51 is in the fourth position and the pressing roller 515 is in contact with the restriction piece 101, the door stop member 36 may be arranged to be slightly separated from the shoji 2. In this case, the shoji 2 is in a state where it can be slightly rocked.

  In the first embodiment, the linkage member 71 includes the linkage bar 711, the locking abutment piece 712, and the rotatable unlocking abutment piece 715. However, the present invention is not limited to this. For example, as shown in FIGS. 20 and 21, the linkage member 71 is provided with an unlocking abutment piece 75 formed in the same manner as the locking abutment piece 712, instead of the rotatable unlocking abutment piece 715. It may be done. The unlocking contact piece 75 is attached to the linkage bar 711 at a large distance from the locking contact piece 712 in the vertical direction. The unlocking abutment piece 75 is disposed lower than the axial center 37 of the horizontal axis at least in the unlocked state shown in FIG. 21 in which the linkage bar 711 is moved downward. 20 shows a locked state by the locking mechanism 7, and FIG. 21 shows an unlocked state by the locking mechanism 7. As shown in FIG.

  When the unlocking contact piece 75 is provided, each configuration of the horizontal axis rotation window 1 is changed as follows. Long holes 243D and 244B which are positioned below the long holes 243B are further formed in the prospect piece part 243 and the indoor looking piece part 244 of the vertical weir 24. An unlocking contact piece 75 is vertically movably passed through the long hole 243D. The contact member 512 is disposed between the locking contact piece 712 and the unlocking contact piece 75 so as to be capable of reciprocating in the vertical direction.

Since the closing movement and locking of the shoji 2 in such a horizontal axis rotation window 1 are performed in the same manner as described above, the description of these operations will be omitted.
The opening movement and the unlocking of the shoji 2 in the horizontal axis rotation window 1 are performed as follows.
First, as shown in FIG. 20, the contact member 512 located at the second position is driven by the drive device 52 to move downward. By this downward movement, the pressing roller 515 is positioned below the axis 37 of the horizontal axis, the forced closing of the shoji 2 by the pressing of the pressing roller 515 is gradually released, and the pressing roller 515 is in a position where the shoji 2 can be fully opened. Reach.
Subsequently, by the further downward movement of the abutment member 512, the shaft member 514 abuts on the unlocking abutment piece 75 and pushes down the unlocking abutment piece 75. As a result of this depression, the linkage bar 711 moves downward to the state shown in FIG. The downward movement of the linkage bar 711 causes the locking unit 72 to unlock as described above.
When unlocked in this manner, the shoji 2 rapidly moves open due to its own weight.

  In the first embodiment, the horizontal axis rotation window 1 including the horizontal axis rotation windows 1A and 1B has been described as one embodiment of the fitting, but the present invention is not limited thereto. For example, the inward window 11 shown in FIGS. May be configured as a fitting. FIG. 22 shows the closed and locked state of the inverted window 11, and FIG. 23 shows the opened and unlocked state of the inverted window 11. FIG.

The internally-inverted window 11 is configured to include a shoji 2, a window frame 3, a closing mechanism 5, and a locking mechanism 7. The lower hook 22 of the shoji 2 is rotatably engaged with the lower frame 32 of the window frame 3, and the shoji 2 is configured to be able to open and close around the engagement portion. The closing mechanism 5 is provided on the window frame 3, and the locking mechanism 7 is provided on the shoji 2.
Further, the shoji 2 is provided with a guide member 27 which protrudes to the indoor side. The guide member 27 includes a guide surface 27A extending along the height direction of the shoji 2 and an inclined guide surface 27B inclined outward from the lower end of the guide surface 27A. The guide member 27 contacts the pressing roller 515 that moves along the longitudinal ridge 24 of the shoji 2 and is configured to be able to guide the shoji 2 in the opening direction and the closing direction.

  The inward turning window 11 operates as follows. As shown in FIG. 23, the upward movement (forward movement) of the contact member 512 located downward causes the shuts 2 to forcibly move closed and the shaft member 514 is disengaged from the movement trajectory of the shaft member 514. It passes without contacting the contact piece 715 and abuts on the locking contact piece 712. By further upward movement of the contact member 512, as shown in FIG. 22, the lock contact piece 712 is pushed up to perform locking by the locking mechanism 7. Thus, closing movement and locking of the shoji 2 are performed.

Further, as shown in FIG. 22, the shaft member 514 contacts the unlocking contact piece 715 located on the movement trajectory of the shaft member 514 by the downward movement (return movement) of the contact member 512 positioned upward. By further downward movement of the contact member 512, the unlocking contact piece 715 is pushed down and the locking mechanism 7 performs the unlocking. Subsequently, the contact member 512 is further moved downward to release the forced closing state of the shoji 2 and allow the shoji 2 to move open. Thus, the unlocking and releasing operation of the shoji 2 is performed.
In addition, such an inverted window 11 may be configured as a single window, or may be configured as two or more continuous windows.

In the first embodiment, the horizontal axis rotation window 1 including the horizontal axis rotation windows 1A and 1B is described as a fitting, but the invention is not limited thereto. For example, natural opening and closing are not possible by wind and the like, and manual opening and closing are possible. It may be constituted by various opening and closing windows constituted by. Also, for example, in addition to the above-mentioned introductory window 11, the vertical axis rotation window, the outlay window (vertical outlay window, horizontal outlay window), the outturn window, the outward window, the outward window, the awning window, etc. Various opening and closing windows may be configured as a fitting.
