JP 2011-64046 A

  In Patent Document 1, since the opening / closing mechanism and the locking mechanism are provided with drive mechanisms such as electric cylinders separately, the mechanism becomes complicated by that amount, and the number of parts increases and becomes bulky. There was a problem.

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

  In order to solve such inconvenience, the present invention supports the shoji 4 in a state in which it can swing in and out of the building in the window frame 3 arranged on the outer wall of the building, and opens and closes the shoji 4. A window opening / closing operation part 11 and a lock part 12 for locking the shoji 4 in a fully closed position, a chain 26 for connecting and interlocking the window opening / closing operation part 11 and the lock part 12, and a chain The chain 26 has a window opening / closing operation section so that the lock section 12 locks the shoji 4 after the window opening / closing operation section 11 fully closes the shoji 4. 11 and the lock part 12 are connected.

  The buildings here include office buildings and apartment buildings. As the driving means, the sprocket 32 is engaged with the chain 26 and the sprocket 32 is rotated by the handle 40 of the handle box 37, the sprocket 32 is rotated by an electric motor or the like, or the electric cylinder is used as the chain. The thing which moves 26 corresponds. The chain 26 and the window opening / closing operation unit 11 and the lock unit 12 include a case where they are directly connected and a case where they are connected via a member such as a rod.

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

  Further, when the shoji 4 is unlocked by the lock portion 12 by the movement of the chain 26, the window opening / closing operation portion 11 can open the shoji 4 in conjunction therewith. Here, the case where the shoji 4 is opened by the dead weight or the weight of the balancer 9 or the like when the window opening / closing operation unit 11 enables the shoji 4 to swing is included. As a means for the window opening / closing operation section 11 to open the shoji 4 when the shoji 4 is unlocked, the lock opening section 12 locks the shoji 4 after the window opening / closing operation section 11 fully closes the shoji 4 and the shoji 4 For example, adjusting the length of the chain 26 or adjusting the positional relationship between the window opening / closing operation part 11 and the lock part 12 so that the window opening / closing operation part 11 opens the shoji 4 when the lock is released.

  The chain 26 may be a push-pull chain. The push-pull chain corresponds to a push-pull chain that can push and pull the window opening / closing operation part 11 and the lock part 12 without excessive bending or breaking.

  Since the window opening and closing device of the present invention can drive the window opening and closing operation unit 11 and the lock unit 12 with a single chain 26, the mechanism for driving the window opening and closing operation unit 11 and the mechanism for driving the lock unit 12 are separately provided. The configuration of the window opening / closing device can be simplified accordingly. Further, since the chain 26 is difficult to be bulky, the window opening / closing device can be made more compact accordingly.

  Moreover, since the chain 26 can be easily bent, it can be reliably and compactly installed even in places where it can be installed only in a bent state. Further, even if the size or shape of the window differs depending on the type of window, it can be dealt with by adjusting the length of the chain 26 or the bending position. The degree of freedom in designing the size and shape of the window can be increased accordingly.

  The window opening / closing operation unit 11 opens the shoji 4 when the shoji 4 is unlocked by the lock unit 12. For example, when the shoji 4 tries to open first, the opening force of the shoji 4 is applied to the lock unit 12. Is prevented, and it is suppressed that the lock is difficult to be released.

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

The hinges 5 are arranged above the vertical vertical centers 3a and 3a of the window frame 3 and the vertical center of the vertical frame 6 arranged in the horizontal center of the window frame 3, respectively. Each shoji 4 is swingable in and out of the building around the hinge 5 and has a glass plate 8 mounted inside the cage 7 that is framed in a square shape.

  As shown in FIG. 1 and FIG. 3, the left and right lateral balancer 9 is provided horizontally on the upper side 7 a of the upper side 7 a of each side 7. 4 is urged so that the upper part of the shoji 4 is inclined toward the inside of the building by its own weight and the weight of the balancer 9 (see FIG. 4). Each window 2 is provided with a water-stopping member made of synthetic rubber or the like along the edge 7 of the shoji 4 or the window frame 3, and when the shoji 4 is in the fully closed posture (posture in FIG. 3). In addition, the gap between the ridge 7 and the window frame 3 (the upright 6) is blocked by the water stop member.

  As shown in FIG. 1, a window opening / closing operation unit 11 for opening / closing each shoji 4 is arranged on the inside of the building of the window frame 3 (standing 6). Further, as shown in FIGS. 1 and 2, along the lower frame 3 b of the window frame 3, a lock portion 12 for locking each shoji 4 in a fully closed posture is disposed.

  As shown in FIGS. 1 and 3, the window opening / closing operation section 11 has a base 10 disposed on the inside of the building of the vertical 6, and is supported by the base 10 so as to be slidable and extends in the vertical direction. A pair of left and right restricting arms 13 and 13, rollers 15 and 15 made of synthetic resin rotatably supported on upper and lower ends of the restricting arms 13, respectively, and one end portion of which is a peristaltic shaft of the restricting arm 13. Drive plate 17 connected to 16 and extending to the vertical 6 side, and an operation plate 18 connected to the drive plate 17 and swinging each regulating arm 13 via the drive plate 17. doing. The operation plate 18 extends in the vertical direction. Each regulating arm 13 is slightly bent toward the inside of the building at the upper and lower intermediate portions.

  The left and right restricting arms 13 and 13 swing in the same posture around the swinging shaft 16. The rollers 15 and 15 of each restricting arm 13 can come into contact with the vertical rod 7b located on the vertical 6 side of the left and right vertical rods 7b of each shoji 4 respectively. The other end of the drive plate 17 has an engagement pin 17 a that engages with an engagement groove 19 provided in the operation plate 18.

  On the lower surface side of the drive plate 17 and in the middle of the length direction, a locking piece 17b protrudes downward. The engagement groove 19 of the operation plate 18 extends in the vertical direction, and the other end side of the engagement groove 19 is bent outward from the building. That is, the engagement groove 19 has a vertical groove portion 19a extending in the vertical direction and a horizontal groove portion 19b extending to the outside of the building. The operation plate 18 is provided with a locking pin 18a that can be locked to the locking piece 17b.

  Guide rails 21 extending in the vertical direction are attached to the base 10, and the guide rails 21 are arranged at two positions in the vertical direction on the back surface (surface on the guide rail 21 side) of the operation plate 18. A pair of upper and lower rollers 20 and 20 are engaged with each other, and the operation plate 18 is movable in the vertical direction along the guide rail 21.

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

  Each lock pin 23 has a base portion 23 a fixed to the slide member 22 and a pin 23 b extending upward from the base portion 23 a, and each receiving member 24 is fixed to the lower surface of the lower collar 7 c of the shoji 4. And a locking portion 24b that protrudes 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 bent obliquely toward the inside of the building. As a result, when the lock pin 23 moves to the lock position (the position of the solid line in FIG. 2) with the slide movement of the slide member 22, the pin 23 b of the lock pin 23 is engaged with the locking portion 24 b of the receiving member 24. The sliding part 4 is pulled toward the window frame 3 by the lock pin 23 by sliding along the locking part 24b from the inclined part toward the locking position, and each sliding part 4 is fully closed. It is locked so that it cannot be opened or closed in posture.

  The left and right slide members 22 and 22 of the lock portion 12 are connected to each other by a fastening member (not shown), and are thereby interlocked. As shown in FIGS. 1 and 2, 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. Are connected to each other. The chain 26 is made of metal such as carbon steel or stainless steel, synthetic resin, or the like.

  Specifically, the one slide member 22 and one end (right end in FIG. 2) of the chain 26 are connected via a connecting member 27 and the like. The other end (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 attached 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 disposed on the inner side of the building at the lower end of the stand 6 and is moved (driven) in the length direction by the sprocket 32. 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 portion of the stand 6 and a horizontally long horizontally extending along the lower frame 3 b of the window frame 3. It is connected to a handle box 37 via a drive rod 34, a bevel gear (not shown) in the bevel gear box 35, and a vertically long connecting rod 36. The drive gear in the drive gear box 33, the drive rod 34, the bevel gear in the bevel gear box 35, the connecting rod 36, and the handle box 37 are connected via a universal joint 38, respectively. .

  Then, 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 is rotated. The chain 26 moves.

  In place of the handle 40 and the handle box 37, the sprocket 32 may be driven to rotate using an electric motor or the like. The chain 26 is bent at a substantially right angle at the position of the sprocket 32.

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

  From this state, for example, when the handle 40 of the handle box 37 is rotated a predetermined number of times in order to enter the ventilation mode, the chain 26 is driven leftward in FIG. However, the pin 23b of each lock pin 23 is disengaged from the locking portion 24b of the receiving member 24 of each shoji 4 (unlocked) (leftward in FIG. 2).

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

  Due to the swinging of each regulating arm 13, the roller 15 of one arm 13 a of each regulating arm 13 is separated from the vertical rod 7 b of each shoji 4, and the upper part of each shoji 4 moves toward the inside of the building by its own weight and the weight of the balancer 9 Each tilts. Each shoji 4 in the tilted state is received by the roller 15 of one arm 13a (state shown in FIG. 4). In this case, the engagement pin 17a of the drive plate 17 is located at the end of the lateral groove portion 19b of the engagement groove 19 of the operation plate 18 on the outer side of the building.

  That is, when the engagement pin 17a of the drive plate 17 is moving in the vertical groove portion 19a of the engagement groove 19 of the operation plate 18, the engagement pin 17a is connected to the vertical groove portion 19a of the engagement groove 19 outside the building. The drive plate 17 (restricting arm 13) is prevented from swinging, but the engagement pin 17a reaches the lateral groove portion 19b at the lower end of the vertical groove portion 19a of the engagement groove 19 by moving the engagement plate 17a. Each regulating arm 13 is allowed to swing and each shoji 4 is opened.

  In the ventilation mode, each shoji 4 can swing at an angle corresponding to the wind pressure of the natural wind. That is, each shoji 4 can swing between the posture of FIG. 4 received by the roller 15 of one arm 13a of each regulating arm 13 and the closed posture where it can be received by the water stop member. . Each shoji 4 may be received in a closed position by an impact buffer member (not shown) or the like.

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

  Further, for example, when the shoji 4 is in the fully closed posture of FIG. 3 and the handle 40 of the handle box 37 is rotated a predetermined number of times in order to enter the smoke exhausting mode, the chain 26 is driven as in the ventilation mode, The pin 23b of each lock pin 23 is released from the locking portion 24b of the receiving member 24 of each shoji 4 (unlocked).

  The operation plate 18 of the window opening / closing operation unit 11 is raised according to the driving of the chain 26, and the raised position is higher than the ventilation mode. Therefore, after the engagement pin 17a of the drive plate 17 reaches the lateral groove portion 19b of the engagement groove 19 of the operation plate 18, the engagement pin 17a is pushed up by the lower side 19c of the engagement groove 19, and each restriction of the window opening / closing operation portion 11 is achieved. The arm 13 rotates to a predetermined smoke exhaust rotation angle (for example, the angle shown in FIG. 5). The rotation angle is larger than that 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 rod 7b of each shoji 4, and the upper part of each shoji 4 is inclined toward the inside of the building. Each tilted shoji 4 can be closed by being received by the roller 15 of the other arm 13b (lower side in FIG. 5) of each restricting arm 13 (state in FIG. 5) even if it is closed by natural wind or the like. Be blocked. In this case, the engagement pin 17a of the drive plate 17 is positioned at the lower end of the vertical groove portion 19a of the engagement groove 19 of the operation plate 18.

  For example, when the handle 40 of the handle box 37 is rotated (reverse to the case of opening the shoji 4) to close each shoji 4 opened in the smoke exhausting posture of FIG. Are driven in the opposite direction. As a result, 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, and accordingly the drive plate 17 rotates counterclockwise in FIG. As a result, the engagement pin 17a once moves to the outside of the building at the lateral groove portion 19b of the engagement groove 19 of the operation plate 18, and further, the inclined shape of the lateral groove portion 19b of the engagement groove 19 of the operation plate 18 is increased. It moves to the vertical groove part 19a side along the upper side 19d, moves up in the vertical groove part 19a, and is pressed down after contacting the upper end of the vertical groove part 19a.

  As a result, the drive plate 17 rotates counterclockwise in FIG. 5, and each regulating arm 13 rotates in the counterclockwise direction in FIG. 5 via the drive plate 17. As a result, the roller 15 of one arm 13a (upper side in FIG. 5) of each regulating arm 13 comes into contact with the vertical rod 7b of each shoji 4 and each shoji 4 is in the fully closed direction (counterclockwise in FIG. 5). ) To fully close (state of FIG. 3).

  When the chain 26 moves, the left and right slide members 22 and 22 of the lock portion 12 slide and move (to the left in FIG. 2), whereby each lock pin 23 of the lock portion 12 receives the receiving member of each shoji 4. Each of the shojis 4 is locked (locked state) by moving to the lock position at 24 (the position of the solid line in FIG. 2).

  That is, the chain 26 connects the window opening / closing operation part 11 and the lock part 12 so that the lock part 12 locks the shoji 4 after the window opening / closing operation part 11 fully closes the shoji 4. Further, when the shoji 4 is unlocked by the lock portion 12 by the movement of the chain 26, the window opening / closing operation portion 11 opens the shoji 4 in conjunction therewith. That is, the window opening / closing operation unit 11 opens the shoji 4 after unlocking the shoji 4.

  In this way, the single chain 26 performs the peristaltic operation of each regulating arm 13 of the window opening / closing operation unit 11 and the locking and unlocking of the shoji 4 by the lock pin 23 of the lock unit 12. 11 and a mechanism for driving the lock pin 23 need not be provided separately. Accordingly, the configuration of the window opening / closing device can be simplified. Further, since the chain 26 can be driven by the sprocket 32, it is less bulky than the case where the window opening / closing operation part 11 and the lock part 12 are driven by each electric cylinder as in Patent Document 1, for example.

  Moreover, since the chain 26 can move while being bent, it can be installed compactly even in places where it can be installed only in a bent state, for example. Further, even if the size or shape of the window differs depending on the type of window, it can be dealt with by adjusting the length of the chain 26 or the bending position.

  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 collar 7 c of the shoji 4. . The chain 26 may be other than a push-pull chain. In the above description, the present invention is applied to a series of windows of two series. However, the present invention can be applied to a single window or three or more windows.
