  Further, inside both the guide rails 1, a chain bending restricting portion 21 (see FIG. 3) for restricting the bending of the window suspension chain 11 hanging from the sprocket 10 of the lifting window drive system is provided. The chain bending restricting portion 21 is configured to slidably sandwich the window suspension chain 11 suspended from the sprocket 10 over the entire length of the suspension to prevent the window suspension chain 11 from being bent. Explained. That is, the chain bend restricting portion 21 is formed of a pair of chain guides 21 a that are formed to project from the center portion of the inner surface of the back wall of the both guide rails 1 and are spaced apart from each other and extend in the longitudinal direction of the guide rail 1. The chain guides 21 a have bending restriction pieces 21 b that are bent in an L shape in the relative direction at the respective leading ends and intervene between the side link plates 12 of the window suspension chain 11. The front end surfaces of the bending restricting pieces 21b are set to be opposed to each other at a larger interval than the outer diameter of the chain roller 13 of the window suspension chain 11.

  Therefore, the chain bending restriction portion 21 is configured to allow the window suspension chain 11 to move up and down between the bending restriction piece portions 21b. In the chain bend restricting portion 21 as described above, the chain guide 21a having the bend restricting piece portion 21b at the tip as described above extends from the lower ends of the both guide rails 1 to a position near the sprocket 10, and the sprocket 10 The bending of the window suspension chain 11 is restricted by the bending restriction piece portion 21b over the entire length of the hanging portion of the window suspension chain 11 hanging from the guide rail 1 to the guide rail 1.

  In the above, the first guide rail 1 and the second guide rail 2 are detachably connected to each other by fastening means such as bolts and nuts to form a unit, and the left and right guide rails 1, 2 Is integrated into a front gate shape by fixed windows 4 and 5, and a window driving device 7 is attached and set to the bracket 6 integrated at the upper end of the first guide rail 1, and meshes with the sprocket 10. One window unit U1 is configured by the lifting window 3 being suspended by the window suspension chain 11 that has been made. This window unit U1 is manufactured at a factory, carried into an installation site, and installed. After the installation, when the lifting window 3 is inclined (shouldered), the snap stopper 18 of the lowermost chain piece 15A of the window suspension chain 11 on one side of the lifting window 3 is removed and the lowermost part is removed. The link pins 14a and 14b are removed from the chain connecting plate 17 together with the chain piece 15A. After the extraction, any one of the pin holes 17a, 17b, and 17c of the chain connecting plate 17 that corresponds to the position where the lifting window 3 can be held in the horizontal position is selected, and the selected pin holes 17a, 17b, and 17c At least the lower link pin 14b of the chain connecting plate 17 is replaced and inserted. Next, by inserting and engaging the snap stopper 18 across the link pins 14a and 14b, the elevating window 3 can be held in a horizontal state without inclination.

Next, the operation will be described.
In the closed state where the elevating window 3 is at the lower limit position between the left and right guide rails 1, when the sprocket 10 at both ends of the rotary shaft 9 is driven to rotate clockwise in FIG. When the window suspension chain 11 that is suspended in the first guide rail 1 is pulled up, the elevating window 3 is raised and opened along the first guide rail 1. At this time, the elevating window 3 is pulled up to the back side (indoor side) of the fixed windows 4, 5, and is raised to a position where the eaves under the elevating window 3 and at least the eaves under the lower fixed window 4 are the same or higher. Stop. When the sprocket 10 is rotationally driven in the counterclockwise direction in the opened state of the lift window 3, the lift window 3 is lowered along the guide rail 1 and stops at the lower limit position.

  The elevating window 3 closed in this way is held in a locked state where there is no fear that it will be lifted even if it is unintentionally lifted and opened from the outside. That is, the opening / closing machine 8 has an interlock function, and the chain pressing member 16 is disposed above the meshing region of the window suspension chain 11 meshed with the sprocket 10, and is suspended in the guide rail 1. When the window suspension chain 11 in the state is sandwiched between the bending restriction piece portions 21b of the chain bending restriction portion 21 and held in a straight state, the window suspension chain 11 is lifted by the lifting force from the outside of the lifting window 3. The window suspension chain 11 is not bent or detached from the sprocket 10 upward. For this reason, the elevating window 3 is locked without requiring any special locking means.

  According to the first embodiment described above, the window suspension chain 11 that is engaged with the sprocket 10 of the window lifting drive system and is suspended in the first guide rail 1 is sandwiched over the entire length of the suspension. 11 is provided in the guide rail 1 so as to prevent the bending of the sprocket 10, and the opening / closing device 8 that rotationally drives the sprocket 10 has an interlock function. Even if it is attempted to lift up and open from the outside, the window suspension chain 11 will not be bent or the sprocket 10 will not be rotated by the lifting force. Therefore, the lifting window 3 is locked in the fully closed position. Thus, there is an effect that the lock function of the elevating window 3 can be obtained without requiring special locking means, and the anti-theft property can be ensured. Further, since the chain pressing member 16 is arranged in the vicinity of the meshing region of the window suspension chain 11 in the sprocket 10, the window suspension chain 11 is moved to the sprocket 10 by lifting the lifting window 3 in the fully closed position. There is an effect that the anti-theft property can be further improved without being deviated from the above.

  Further, the chain bend restricting portion 21 is configured to interpose a bend restricting piece portion 21b bent in a relative direction at the distal ends of a pair of left and right chain guides 21a between both side link plates 12 of the window suspension chain 11. Therefore, there is an effect that the elevating window 3 can be always moved up and down smoothly without interference between the elevating window 3 and the chain bending restricting portion 21 during the elevating operation of the elevating window 3. Moreover, since the chain bending restricting portion 21 extends in the longitudinal direction within the first guide rail 1, a hollow columnar mold material is applied as the first guide rail 1 integrally having the chain bending restricting portion 21. Even in the second guide rail 2, a hollow columnar mold material can be applied, and the window unit U1 can be manufactured at the factory and carried into the installation site, thereby reducing the construction time at the installation site. There is an effect that it can be greatly shortened. Furthermore, when the window unit U1 is carried in, the window suspension chain 11 does not dance in the first guide rail 1 and the lifting window 3 does not swing, so that the window unit U1 can be carried in easily. There is an effect that can be.

  Furthermore, in the said Embodiment 1, although it was set as the combination structure of the raising / lowering window 3 and the fixed windows 4 and 5, the said raising / lowering window 3 is the 2nd guide rail 2 to which the said fixed windows 4 and 5 were attached and fixed. Since it is configured to move up and down along another first guide rail 1, the lifting window 3 can be moved up and down regardless of the fixed windows 4 and 5. That is, the sprocket 10 engaged with the window suspension chain 11 that suspends the elevating window 3 that elevates and lowers along the first guide rail 1 so as to pass the fixed windows 4 and 5 is connected to the first guide rail 1. So that the elevating window 3 can be lifted up to a position near the sprocket 10 regardless of the fixed windows 4, 5. Therefore, a so-called hoisting machine unit of the window drive device 7 system including the sprocket 10 is provided. Even if the height of the fixed windows 4 and 5 hanging from the ceiling under the ceiling (the dimension of the hanging from the ceiling) is shorter than the height of the lift window 3, the lift window 3 and the fixed window 4 are fixed. The elevating window 3 can be raised to a position where the eaves under the eaves are the same. Therefore, the lifting stroke of the lifting window 3 is not restricted by the fixed windows 4 and 5, and the lifting stroke of the lifting window, particularly the opening area (window opening area) of the lifting window 3 can be freely set. There is an effect. Further, there is an effect that even if the size of the elevating window 3 and the fixed windows 4 and 5 are different, they can be accommodated so as to overlap each other.

  The elevating window 3 and the fixed window 4 may be arranged alternately at predetermined opening intervals in the vertical direction so that the elevating window 3 moves up and down like the fixed window 4. A plurality of window openings formed between a plurality of fixed windows 3 adjacent to each other at a predetermined interval in the direction are simultaneously opened and closed by a plurality of elevating windows 3 connected in series in the vertical direction via a window suspension chain 11. There is an effect that can be done. Therefore, there is an effect that the window opening area can be set freely.

  Furthermore, according to the first embodiment, the lowermost chain piece 15a of the window suspension chain 11 hanging in the first guide rail 1 can be attached and detached, and the chain connecting plates are provided on both upper sides of the elevating window 3. 17 is provided, and a plurality of pin holes 17a, 17b, 17c are provided in the longitudinal direction of the chain connecting plate 17, and the interval between the pin holes 17a, 17b, 17c is set so that the link pins 14 of the window suspension chain 11 and 14a, 14b is set to be shorter than the pitch between the pin holes 17a, 17b, 17c, and the link pins 14a, 14b of the lowermost chain piece 15A are inserted, and the link pins 14a, 14b are inserted. Since the snap stopper 18 is detachably fitted and engaged across the window, the shoulder of the elevating window 3 is lowered after the installation of the window unit U1 on site. When the inclination) occurs, an adjustment is made to correct the inclination of the elevating window 3 by replacing and inserting at least the lower link pin 14b of the link pin 14a, 14 into any of the pin holes 17a, 17b, 17c. There is an effect that it can be easily performed. Further, as described above, since the window suspension chain 11 suspended in the first guide rail 1 is sandwiched and held by the chain bending restricting portion 21, the internal space of the first guide rail 1 is maintained. The electrical wiring can be performed without any trouble.

In the fifth embodiment, the chain end portion 11a opposite to the lifting side of the lifting window 3 in the window hanging chain 11 applied in each of the embodiments is viewed from the axial direction of the sprocket 10 in the sprocket 10. And the window driving device 7 (including the opening / closing device 8 of each embodiment), the sprocket 10 is fixed to the bracket 6 side at a position higher than the upper end of the outer periphery. Then, between the fixed point of the chain end 11a of the window suspension chain 11 and the sprocket 10, there is a play in which the window suspension chain 11 hangs smoothly from the sprocket 10 when the elevation window 3 is moved up and down. The interval is set.

  According to such a configuration of the fifth embodiment, when the chain end 11a of the window suspension chain 11 is fixed at a position below the lower end of the outer periphery of the sprocket 10 between the opening / closing device 8 and the sprocket 10. Compared to the above, the window suspension chain 11 that hangs down from the sprocket 10 in a substantially U shape during the lifting operation of the lifting window 3 has a shorter suspending excess length. Thus, the lifting / lowering operation of the lifting / lowering window 3 can be realized smoothly at all times, and the height of the window driving device 7, particularly the height of the driving unit, can be reduced. Further, by setting a play interval in which the window suspension chain 11 hangs down between the fixed point of the chain end portion 11 a of the window suspension chain 11 and the sprocket 10, the lifting window 3 can be lifted from the sprocket 10. In addition to shortening the surplus length of the window suspension chain 11 that hangs down, there is an effect that the degree of freedom of the window suspension chain can be obtained.

  The chain end 11a of the window suspension chain 11 is most preferably fixed at the same horizontal position as the outer peripheral upper end of the sprocket 10, but the fixing point is located above the lower peripheral lower end of the sprocket 10. The same effect can be obtained in any case.

Embodiment 6 FIG.
In this sixth embodiment, as shown in FIG. 11, a chain tray 25 is arranged below the sprocket 10 between the fixed point of the chain end 11 a of the window suspension chain 11 in the fifth embodiment. is there. The chain tray 25 receives and stores a surplus hanging portion of the window suspension chain 11 that hangs down from the sprocket 10 when the elevating window 3 is pulled up, and is configured to restrict the bending of the window suspension chain 11 during the storage. ing. As the bending restricting means, the length of the left and right of the chain tray 25 is minimized so that the window suspension chain 11 accommodated in the chain tray 25 is not entangled twice. The width of the chain 11 is set to be not less than 1 and not more than 2 times the chain width, and can be stored while restricting the bending of the window suspension chain 11. The chain tray 25 may be configured to have elasticity capable of buffering the window suspension chain 11 accommodated therein.

  According to the sixth embodiment described above, the chain tray 25 for receiving and storing the surplus hanging portion of the window suspension chain 11 that hangs down from the sprocket 10 when the elevating window 3 is pulled up is disposed. Since the chain tray 25 is configured so that the bending of the window suspension chain 11 is restricted when the window suspension chain 11 is stored, the window suspension chain 11 is extended from the sprocket 10 when the lifting window 3 is pulled up. There is an effect that it does not hang down and protrude from the hoisting machine unit (unitized portion of the entire window driving device 7). Moreover, since the length of the left and right sides is minimized by setting the chain tray 25 to a width dimension of 1 to 2 times the chain width of the window suspension chain 11, There is an effect that the window suspension chain 11 housed in the window drive chain 11 is not entangled and the entire width (left-right width) of the window drive device 7 can be made compact. Further, by forming the chain tray 25 with an elastic material or having an elastic tank on the inner surface, the window suspension chain 11 suspended and stored in the chain tray 25 is buffered and the window suspension chain 11 is buffered. A muffler effect that can absorb the collision sound is also obtained.
