At this time, the second moving member 125 is moved in the opening direction for opening the casement window 10 along the transfer screw 132 or in the closing direction for closing, the second section where the second male screw portion 132b is formed Can only be moved within.

That is, in the closed state of the casement window 10, when the transfer screw 132 is rotated in the forward direction by operating the transfer motor 134, the screw portion formed in the first moving member 121 and the second moving member 125 Since the shapes are different, the first moving member 121 and the second moving member 125 may be moved in a direction closer to each other to make the casement window 10 open.

Conversely, when the casement window 10 is opened, the transfer motor 134 is operated to rotate the transfer screw 132 in the reverse direction, so that the first moving member 121 and the second moving member 125 are separated from each other. It can be moved to make the casement window 10 closed.

Meanwhile, a third section in which the first male screw portion 132a or the second male screw portion 132b is not formed may be formed on the outer circumferential surface of the transfer screw 132. When the first moving member 121 and the second moving member 125 are moved along the transfer screw 132 in the direction of approaching, the first moving member 121 and the second moving member 125 by the third section ) Is no longer moved in the direction of getting closer, and the first moving member 121 and the second moving member 125 can be stopped at the position.

That is, the movement positions of the first moving member 121 and the second moving member 125 may be limited by the third section in which the male screw portion is not formed on the outer circumferential surface of the transfer screw 132, which will be described later. 138).

In addition, referring to FIG. 3, a limit switch 138 may be provided in the opening/closing driving unit 130. The limit switch 138 may be provided adjacent to the transfer screw 132 to limit the moving positions of the first moving member 121 and the second moving member 125.

Specifically, the limit switch 138 detects that the first moving member 121 and the second moving member 125 are in contact, wherein the first moving member 121 is rotated in the forward direction of the transfer screw 132 and When the second moving member 125 is moved in a direction closer to each other, the second moving member 125 may be restricted so that it no longer closes.

For reference, the opening/closing driving unit 130 is not in the form of a screw, and various structures capable of forcibly moving the moving member 120 may be used. For example, the body transfer unit 134 may be formed of a transfer structure using a belt and a pulley, a transfer structure using a wire and bobbin, a transfer structure using a rack and pinion, a transfer structure using a screw, or the like. In the transfer structure using the belt and the pulley, the moving member 120 can be transferred while the belt is moved by the pulley while the moving member 120 is connected to the belt. In the transfer structure using the wire and the bobbin, the moving member 120 may be transferred while the wire is loosened or wound by the bobbin while the moving member 120 is connected to the wire. In the transfer structure using the rack and the pinion, the moving member 120 may be transferred while the rack gear is moved by the pinion gear while the moving member 120 is connected to the rack gear.

On the other hand, referring to Figures 4 and 5, in the receiving portion 102 in order to close the casement window 10, the first moving member 121 and the second moving member 125 away from each other, that is, the casement window ( When transferred in the closing direction of 10), a fixing member 136 for fixing a maximum distance between the first moving member 121 and the second moving member 125 may be provided.

The fixing member 136 is provided at both ends of the transfer screw 132, the movement when the first moving member 121 and the second moving member 125 are moved away from each other for closing the casement 10 You can limit the location.

For reference, a transfer motor 134 may be mounted to one end of the transfer screw 132, that is, the fixing member 136 provided on the side of the transfer screw 132 where the first moving member 121 is located. Accordingly, the transfer motor 134 can be more stably combined with the transfer screw 132.

The opening/closing control unit 139 may be connected to the opening/closing driving unit 130 so as to control the operation of the opening/closing driving unit 130. That is, the opening/closing control unit 139 may be connected to the transfer motor 134 to enable signal transmission.

For reference, the drawing shows that one opening/closing control unit 139 is provided, but is not limited thereto. For example, when a plurality of casement windows 10 are provided, the opening/closing control unit 139 may be installed one by one in the casement window 10 to individually control the opening/closing operation of the casement window 10, or one opening/closing control unit (139) may be connected to the plurality of casement windows 10 to simultaneously control the opening and closing operations of the plurality of casement windows 10.

On the other hand, with reference to Figures 3 to 6, the operation of the casement window opening and closing device 100 according to an embodiment of the present invention will be briefly described.

First, when a fire generation signal or a smoke generation signal is transmitted to the opening/closing control unit 139, the opening/closing control unit 139 drives the transfer motor 134 of the opening/closing driving unit 130 in the forward direction. Then, the transfer screw 132 of the opening/closing driving unit 130 is rotated in the forward direction by the transfer motor 134.

When the transfer screw 132 is rotated in the forward direction, the transfer screw 132 moves the first moving member 121 and the second moving member 125 in the opening direction of the window 14. Accordingly, when the first moving member 121 and the second moving member 125 are close to each other, the force pushing the first connecting portion 111 away from the window frame 12 and pushing the first connecting portion 111 By the second connecting portion 115 and the third connecting portion 117 is also pushed in the direction away from the window frame (12). At this time, the opening and closing angle θ1 between the first link 112 and the second link 113 based on the first connection unit 111 becomes an acute angle smaller than 90 degrees, and the second connection unit 115 and the second 3 The distance between the connecting portions 117 is getting closer.

Therefore, when the first moving member 121 and the second moving member 125 are moved in a direction closer to each other, the first connecting portion 111, the second connecting portion 115 and the third connecting portion 117 The first link 112, the second link 113, the first connection link 114, and the second connection link 116 by the force of the window 14 in the direction away from the window frame 12 casement window 10 is opened. In this case, the smoke generated by the fire in the interior of the building through the casement window 10 is discharged to the outside to prevent the damage caused by the smoke.

On the other hand, if it is determined that the opening of the casement window 10 is unnecessary, the opening/closing control unit 139 drives the transfer motor 134 of the opening/closing driving unit 130 in the reverse direction, and the transfer motor 134 transfer screw 132 Rotate in the reverse direction.

When the transfer screw 132 is rotated in the reverse direction, the transfer screw 132 forces the first moving member 121 and the second moving member 125 to be closed in a closed direction, that is, close to each other. When the first moving member 121 and the second moving member 125 are moved away from each other as the first moving member 121 and the second moving member 125 are moved in the closed direction, the first link 112, the first The two links 113, the first connection link 114, and the second connection link 116 pull the window 14 in the direction of approaching the window frame 12. Then, the first link 112, the second link 113, the first connection link 114 and the second connection link 116 are folded. At this time, the opening/closing angle θ between the first link 112 and the second link 113 based on the first connection part 111 becomes an obtuse angle greater than 90, and the second connection part 115 and the third The distance between the connecting portions 117 also increases.

Therefore, when the first moving member 121 and the second moving member 125 are moved in a direction away from each other, the first connection unit 111, the second connection unit 115 and the third connection unit 117, the first centered By the pulling force of the link 112, the second link 113, the first connection link 114, and the second connection link 116, the window 14 is moved in a direction closer to the window frame 12 to open and close the casement window. 10 is closed.

As described above, the first link 112 and the second link 113 are cross-linked to form a first connection 111 and a first connection to each of the first link 112 and the second link 113 As the link 114 and the second connection link 116 are connected to form the second connection portion 115 and the third connection portion 117, the first link 112 and the second link are opened and closed when the casement window 10 is opened or closed. The working force of the link 113 can be transmitted to the window 14 more efficiently. That is, since the operating force of the first link 112 and the second link 113 connected to the first moving member 121 and the second moving member 125 respectively operates perpendicular to the window 14, the casement window The opening and closing of the casement window 10 even when the casement window 10 is closed by the first link 112, the second link 113, the first connection link 114, and the second connection link 116 during opening and closing of the case 10 ) To transmit the operating force in the direction of opening.

As described above, in one embodiment of the present invention, it has been described by specific matters such as specific components, etc., and by limited embodiments and drawings, which are provided to help a more comprehensive understanding of the present invention, and the present invention It is not limited, and those skilled in the art to which the present invention pertains can make various modifications and variations from these descriptions.
