  In Patent Document 1, since the opening and closing mechanism and the lock mechanism are separately provided with a drive mechanism such as an electric cylinder, the mechanism becomes complicated by that amount, and the number of parts increases and the volume increases. There was such a problem.

  The present invention has been provided for the purpose of solving such inconvenience, and it is an object of the present invention to provide a window opening / closing device capable of simplifying a mechanism for opening / closing and locking a window.

  According to the present invention, in order to solve such inconvenience, a shoji 4 is supported in a window frame 3 arranged on an outer wall of a building so as to be swingable in and out of the building. A window opening / closing operation section 11 and a lock section 12 for locking the shoji 4 in a fully closed position, a chain 26 for connecting and interlocking the window opening / closing operation section 11 and the lock section 12, And a drive means for moving the window 26 in the length direction. The chain 26 is provided with a window opening / closing operation unit such that the lock unit 12 locks the sash 4 after the window opening / closing operation unit 11 fully closes the sash 4. 11 and the lock portion 12 are connected.

  The buildings here include office buildings and condominium buildings. The driving means includes a sprocket 32 meshed with the chain 26, and the sprocket 32 is rotated by the handle 40 of the handle box 37; a sprocket 32 is driven to rotate by an electric motor; The one that moves 26 corresponds to this. The chain 26 may be directly connected to the window opening / closing operation unit 11 or the lock unit 12 or may be connected via a member such as a rod.

  Means for adjusting the timing so that the lock unit 12 locks the sash 4 after the window opening / closing operation unit 11 fully closes the sash 4 include, for example, a unit that adjusts the timing by adjusting the length of the chain 26, and a method for adjusting the timing. A device that adjusts the timing by adjusting the positional relationship between the operation unit 11 and the lock unit 12 is applicable. Here, the case where the chain 26 is bent or curved in the middle of the length direction is also included. The fully closed position of the shoji 4 includes not only the position in which the shoji 4 is completely closed but also the position in which the shoji 4 is slightly opened. The present invention can be applied to a horizontal rotation window, a vertical rotation window, and the like.

  Further, when the lock of the sash 4 by the lock unit 12 is released by the movement of the chain 26, the window opening / closing operation unit 11 can open the sash 4 in conjunction therewith. Here, the window opening / closing operation unit 11 allows the sash 4 to swing, so that the sash 4 is opened due to its own weight, the weight of the balancer 9, or the like, or is opened by the urging force of a spring. As means for the window opening / closing operation unit 11 to open the sash 4 when the lock of the sash 4 is released, the lock unit 12 locks the sash 4 after the window opening / closing operation unit 11 fully closes the sash 4, and For example, the length of the chain 26 is adjusted, or the positional relationship between the window opening / closing operation section 11 and the lock section 12 is adjusted so that the window opening / closing operation section 11 opens the shoji 4 when the lock is released.

  Further, the chain 26 may be a push-pull chain. A push-pull chain that can push or pull the window opening / closing operation unit 11 or the lock unit 12 without excessive bending or breaking corresponds to the push-pull chain.

  In the window opening / closing device of the present invention, the window opening / closing operation section 11 and the lock section 12 can be driven by one chain 26. Therefore, a mechanism for driving the window opening / closing operation section 11 and a mechanism for driving the lock section 12 are separately provided. And the configuration of the window opening / closing device can be simplified accordingly. Further, since the chain 26 is hard to be bulky, the size of the window opening / closing device can be reduced by that much.

  Moreover, since the chain 26 can be easily bent, it can be reliably and compactly installed even in a place where the chain 26 can be installed only in a bent state, for example. Further, even if the size, shape, and the like of the window are different depending on the type of the window, it can be handled by adjusting the length of the chain 26, the bending position, and the like. The degree of freedom in designing the size and shape of the window can be increased accordingly.

  Since the window opening / closing operation unit 11 opens the sash 4 when the lock of the sash 4 by the lock unit 12 is released, for example, the opening force of the sash 4 is applied to the lock unit 12 by opening the sash 4 first. Is prevented, making it difficult to release the lock.

  When the chain 26 is a push-pull chain, the window opening / closing operation unit 11 and the lock unit 12 can be driven firmly by the chain 26.

  As shown in FIG. 2, the lock portion 12 includes a pair of left and right guide rails 21 extending in the left-right direction along the lower frame 3 b of the window frame 3, and slides in the left-right direction along the respective guide rails 21. A pair of left and right sliding members 22 that move, a pair of left and right lock pins 23 that are respectively arranged on the upper surface of each slide member 22, and a pair of sliding doors 4 corresponding to the lock pins 23. It has a pair of left and right receiving members 24, 24 respectively arranged on the lower surface of the lower frame 7c.

  Each lock pin 23 has a base 23a fixed to the slide member 22 and a pin 23b extending upward from the base 23a. Each receiving member 24 is fixed to the lower surface of the lower frame 7c of the shoji 4. And a locking portion 24b protruding downward from the base 24a.

  The locking portion 24b of the receiving member 24 extends in the left-right direction, and the left end is obliquely bent toward the inside of the building. Accordingly, when the lock pin 23 moves to the lock position (the position shown by the solid line in FIG. 2) along with the slide movement of the slide member 22, the pin 23b of the lock pin 23 is moved to the locking portion 24b of the receiving member 24. , And slides from the inclined portion toward the lock position along the locking portion 24b, whereby each of the shoji 4 is drawn toward the window frame 3 by the lock pin 23, and each of the shoji 4 is fully closed. Locked to prevent opening and closing in the posture.

  The left and right slide members 22, 22 of the lock portion 12 are connected to each other by a fastening member (not shown) so as to be linked. As shown in FIGS. 1 and 2, the one slide member 22 (right side in FIG. 2) of the lock portion 12 and the operation plate 18 of the window opening / closing operation portion 11 form a chain (push-pull chain) 26 having a predetermined length. Connected to each other. The chain 26 is made of a metal such as carbon steel or stainless steel, or a synthetic resin.

  Specifically, the one slide member 22 and one end (the right end in FIG. 2) of the chain 26 are connected via a connecting member 27 or the like. The other end (the upper left end in FIG. 1) of the chain 26 is connected to the operation plate 18 via a connecting rod 28 (FIG. 3) or the like. The lower side of the chain 26 is housed in a horizontally long chain box 29, and the chain box 29 is mounted on a base plate 30 fixed to the lower frame 3 b of the window frame 3.

As shown in FIG. 1, the chain 26 meshes with a sprocket 32 arranged at the lower end of the cubic 6 on the inside of the building, and is moved (driven) by the sprocket 32 in the longitudinal direction. The sprocket 32 has a drive gear (not shown) in a drive gear box 33 disposed on the inside of the building at the lower end of the cubic 6, and has a horizontally-long left-right side extending along the lower frame 3 b of the window frame 3. A drive rod 34, a bevel gear (not shown) in a bevel gear box 35, and a vertically long connecting rod 36 are connected to a handle box 37. The drive gear in the drive gear box 33, the drive rod 34, the bevel gear in the bevel gear box 35, the connection rod 36, and the handle box 37 are connected via a universal joint 38, respectively. .

  By rotating the handle 40 of the handle box 37, the rotation is transmitted to the drive gear box 33 via the connecting rod 36, the bevel gear box 35, and the drive rod 34, whereby the sprocket 32 rotates. The chain 26 moves.

  Note that, instead of the handle 40 and the handle box 37, the sprocket 32 may be rotationally driven using an electric motor or the like. The chain 26 is bent substantially at a right angle at the position of the sprocket 32.

  Next, an operation example of the horizontal axis rotating window to which the window opening / closing device according to the present invention is applied will be described. When the shoji 4 of each window 2 is in the fully closed position shown in FIG. 3, each lock pin 23 of the lock portion 12 is in the lock position (the position shown by the solid line in FIG. 2) of the respective shoji 4 by the receiving member 24. It is located and each sash 4 is locked (locked state). At this time, the roller 15 of one arm 13a of each regulating arm 13 is in contact with the vertical frame 7b of each shoji 4 (the state of FIG. 3), and each shoji 4 is fully closed. The engagement pin 17 a of the drive plate 17 of the window opening / closing operation section 11 is located on the upper end side of the vertical groove 19 a of the engagement groove 19 of the operation plate 18.

  In this state, when the handle 40 of the handle box 37 is rotated a predetermined number of times, for example, to set the ventilation mode, the chain 26 is driven to the left in FIG. 2 (leftward in FIG. 2), the pins 23b of the lock pins 23 are respectively disengaged from the locking portions 24b of the receiving members 24 of the sash 4 (unlocked).

  At this time, since the other end of the chain 26 rises, the operation plate 18 of the window opening / closing operation unit 11 rises accordingly. Thereby, when the engagement pin 17a of the drive plate 17 relatively descends the vertical groove 19a of the engagement groove 19 of the operation plate 18 and reaches the lower end of the vertical groove 19a of the engagement groove 19, the engagement groove It moves to the building exterior side (left side in FIG. 3) along the horizontal groove part 19b of 19. Along with the movement, the drive plate 17 swings clockwise in FIG. 3 around the swing shaft 16, and accordingly, each regulating arm 13 swings clockwise in FIG. (Posture of FIG. 4).

  Due to the swing of each regulating arm 13, the roller 15 of one arm 13 a of each regulating arm 13 is separated from the vertical frame 7 b of each sliding door 4, and the upper part of each sliding door 4 moves toward the inside of the building due to its own weight and the weight of the balancer 9. Tilt each. Each of the inclined sashes 4 is received by the roller 15 of the one arm 13a (the state of FIG. 4). In this case, the engagement pin 17a of the drive plate 17 is located at the end of the lateral groove 19b of the engagement groove 19 of the operation plate 18 on the outside of the building.

  In other words, when the engagement pin 17a of the drive plate 17 is moving inside the vertical groove 19a of the engagement groove 19 of the operation plate 18, the engagement pin 17a is located outside the vertical groove 19a of the engagement groove 19 outside the building. Of the drive plate 17 (restriction arm 13) is suppressed, but the engagement pin 17a reaches the horizontal groove 19b at the lower end of the vertical groove 19a of the engagement groove 19. Then, each regulating arm 13 can swing, and each shoji 4 is opened.

In the ventilation mode, each sash 4 can swing at an angle corresponding to the wind pressure of the natural wind.
In other words, each of the sashes 4 is swingable from the position shown in FIG. 4 received by the roller 15 of the one arm 13a of each regulating arm 13 to the closed position that can be received by the water stopping member. . Note that each of the sashes 4 may be received in a closed position by an impact buffer member (not shown) or the like.

  As described above, in the ventilation mode, each shoji 4 swings at an angle corresponding to the wind pressure of the natural wind. For example, in the case of a weak wind or a weak wind (when the wind pressure of the natural wind is low), the outside air is taken into the building. While proper ventilation is possible, in the case of strong winds (when the wind pressure of natural wind is high), each shoji 4 closes and the strong wind blows into the building as it is to blow off documents etc. placed in the building. Etc. can be suppressed.

  Further, for example, when the handle 40 of the handle box 37 is rotated a predetermined number of times to set the smoke exhaust mode in the fully closed posture of FIG. 3, the chain 26 is driven in the same manner as in the ventilation mode, The pins 23b of the lock pins 23 are respectively disengaged from the locking portions 24b of the receiving members 24 of the sash 4 (unlocked).

  The operation plate 18 of the window opening / closing operation unit 11 rises in accordance with the driving of the chain 26, and the rising position is higher than the ventilation mode. Therefore, after the engaging pin 17 a of the driving plate 17 reaches the lateral groove 19 b of the engaging groove 19 of the operation plate 18, it is pushed up by the lower side 19 c of the engaging groove 19, and the restriction of the window opening / closing operation unit 11 is performed. The arms 13 respectively rotate to a predetermined smoke exhaust rotation angle (for example, the angle in FIG. 5). The rotation angle is larger than in the ventilation mode.

  With the rotation of each regulating arm 13, the roller 15 of one arm 13a of each regulating arm 13 separates from the vertical frame 7b of each sliding door 4, and the upper part of each sliding door 4 tilts toward the inside of the building. Even if the inclined sash 4 is closed by natural wind or the like, it is received by the roller 15 of the other arm 13b (the lower side in FIG. 5) of each of the regulating arms 13 (the state of FIG. 5) and can be closed. Will be blocked. In this case, the engagement pin 17a of the drive plate 17 is located at the lower end of the vertical groove 19a of the engagement groove 19 of the operation plate 18.

  For example, when the handle 40 of the handle box 37 is rotated (rotated in a direction opposite to the case where the shoji 4 is opened) to close each of the shoji 4 opened in the smoke exhausting posture of FIG. Are driven in the opposite direction. Thereby, the operation plate 18 of the window opening / closing operation unit 11 is lowered.

  Then, the locking pin 18a of the operation plate 18 pushes down the locking piece 17b of the drive plate 17, whereby the drive plate 17 rotates counterclockwise in FIG. As a result, the engagement pin 17a temporarily moves to the outside of the building at the lateral groove 19b of the engagement groove 19 of the operation plate 18, and the inclined shape of the lateral groove 19b of the engagement groove 19 of the operation plate 18 is further moved. Moves along the upper side 19d to the side of the vertical groove 19a, rises in the vertical groove 19a, contacts the upper end of the vertical groove 19a, and is then pushed down.

  Thereby, the drive plate 17 rotates counterclockwise in FIG. 5, and each regulating arm 13 rotates counterclockwise in FIG. 5 via the drive plate 17. As a result, the roller 15 on one arm 13a (upper side in FIG. 5) of each of the regulation arms 13 abuts on the vertical frame 7b of each of the sliding doors 4, and each of the sliding doors 4 is fully closed (counterclockwise in FIG. 5). ) To fully close (state of FIG. 3).

When the chain 26 moves, the left and right slide members 22 of the lock portion 12 slide (leftward in FIG. 2), whereby the lock pins 23 of the lock portion 12 move to the receiving members of the respective sliding doors 4. The sash 4 is moved to the lock position at 24 (the position indicated by the solid line in FIG. 2) and locked (locked state).

  That is, the chain 26 connects the window opening / closing operation unit 11 and the lock unit 12 so that the lock unit 12 locks the sash 4 after the window opening / closing operation unit 11 fully closes the sash 4. Further, when the lock of the shoji 4 by the lock unit 12 is released by the movement of the chain 26, the window opening / closing operation unit 11 opens the shoji 4 in conjunction with the unlock. That is, after the lock of the shoji 4 is released, the window opening / closing operation unit 11 opens the shoji 4.

  As described above, the swing operation of each regulating arm 13 of the window opening / closing operation section 11 and the locking and unlocking of the sash 4 by the lock pin 23 of the lock section 12 are performed by the single chain 26. It is not necessary to separately provide a mechanism for operating the lock 11 and a mechanism for driving the lock pin 23. The configuration of the window opening / closing device can be simplified accordingly. In addition, since the chain 26 can be driven by the sprocket 32, it does not have to be bulky as compared with the case where the window opening / closing operation unit 11 and the lock unit 12 are driven by each electric cylinder as in Patent Document 1, for example.

  Moreover, since the chain 26 can move while bending, it can be compactly installed even in a place where it can be installed only in a bent state, for example. Further, even if the size, shape, and the like of the window are different depending on the type of the window, it can be handled by adjusting the length of the chain 26, the bending position, and the like.

  Note that the window opening / closing operation unit 11 may have a configuration other than the configuration described above. As the lock portion 12, the receiving member 24 may be disposed on the upper surface of the slide member 22, and the lock pin 23 may be disposed on the lower surface of the lower frame 7c of the shoji 4, or other configurations may be employed. . The chain 26 may be other than a push-pull chain. In the above description, the present invention is applied to a pair of continuous windows. However, the present invention can be applied to a single window or a window having three or more windows.
