The present invention relates to a casement window opening and closing device, and more particularly, to a casement window opening and closing device capable of opening and closing a casement type window in a simple and stable structure in the vertical direction.

Many windows are installed in buildings such as apartments, high-rise buildings, and factories for indoor exhaust, ventilation, and lighting purposes. Such a window is a device made to open and open an opening in the wall for ventilation and lighting indoors.

Various methods such as sliding doors, casements, and tilting are used depending on the opening and closing method of the window, and it is common to install the window by different opening and closing methods depending on the location and purpose of which the window is used.

On the other hand, the exhaust ventilation facility is a facility that prevents the outflow of smoke from the fire source to the evacuation route in the event of a fire in a building, and includes a smoke-retardant wall, exhaust research, exhaust duct, exhaust smoke, and exhaust windows. In the event of a fire in a building, the above-described exhaust ventilation facility smoothly promotes evacuation and fire extinguishing activities and at the same time plays a role of removing smoke generated during a fire in order to prevent accidents caused by suffocation.

Specifically, the building's exhaust ventilation system is installed as an evacuation measure in case of fire. In other words, the fire generated in the building accompanies smoke, and since the smoke contains toxic gases, the generated smoke has a greater influence on the evacuation of people and the damage to human life than the flame caused by the fire. For example, if a fire occurs in a high-rise building, even if the flame does not spread to the upper floor, the smoke generated from the lower floor rises rapidly and interferes with people's evacuation, fire extinguishing, and life-saving activities, thus directly affecting human life. give. Accordingly, it is necessary to quickly discharge smoke from a fire, which is an obstacle to evacuation of people, fire extinguishing and lifesaving activities, etc. in buildings.

Accordingly, in the case of a flue-ventilation window used in a flue-smoking facility, it has the purpose of discharging toxic gas or ventilating when a fire occurs, and is formed in a structure that automatically opens and closes by detecting a fire. Accordingly, an exhaust window opening and closing device for automatically opening and closing the exhaust window in the event of a fire is installed in the exhaust window. The opening/closing device of the exhaust window is connected to a fire fighting system installed in a building, and opening and closing can be automatically controlled according to a control signal of the fire fighting system.

In addition, the second male screw portion 132b formed in the second section of the transfer screw 132 may be coupled to the female screw portion formed in the second coupling portion 1218 of the second moving member 125. At this time, the second moving member 125 is moved in the opening direction for opening the casement 10 or the closing direction for closing the casement 10 along the transfer screw 132, and the second section in which the second male screw part 132b is formed. Can only be moved within.

That is, in the closed state of the casement 10, when the transfer motor 134 is operated to rotate the transfer screw 132 in the forward direction, the screw portions formed on the first moving member 121 and the second moving member 125 Since the shape is different, the first moving member 121 and the second moving member 125 are moved in a direction closer to each other, thereby making the casement window 10 open.

Conversely, in the open state of the casement 10, when the transfer motor 134 is operated to rotate the transfer screw 132 in the reverse direction, the first moving member 121 and the second moving member 125 are separated from each other. It is moved to the casement window 10 can be made into a closed state.

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 peripheral 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 approaching direction, the first moving member 121 and the second moving member 125 are moved by the third section. ) Is no longer moved in the approaching direction, and the first moving member 121 and the second moving member 125 can be stopped at that position.

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

Also, 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, and at this time, the first moving member 121 and the first moving member 121 and the second moving member 121 are rotated in the forward direction of the transfer screw 132 and When the second moving members 125 are moved in a direction closer to each other, it is possible to restrict them so that they are no longer closer.

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 a bobbin, a transfer structure using a rack and pinion, a transfer structure using a screw, and the like. In the transfer structure using a belt and a pulley, the moving member 120 may 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 a wire and a bobbin, the moving member 120 may be transferred while the wire is unwound or wound by the bobbin while the moving member 120 is connected to the wire. In a transport structure using a rack and a pinion, the rack gear may be moved by the pinion gear while the movable member 120 is connected to the rack gear, thereby transferring the movable member 120.

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

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

For reference, the transfer motor 134 may be mounted on 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 may be more stably coupled with the transfer screw 132.

The opening/closing control unit 139 may be connected to the opening/closing driving unit 130 to transmit signals 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 transmit signals.

For reference, although one opening/closing control unit 139 is shown in the drawing, it is not limited thereto. For example, when a plurality of casement windows 10 are provided, the opening/closing control unit 139 may be installed on the casement window 10 one by one to individually control the opening and closing operation of the casement window 10, or one opening/closing control unit It is also possible to simultaneously control the opening and closing operation of the plurality of casement windows 10 by connecting 139 to the plurality of casement windows 10.

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

First, when a fire generating signal or a smoke generating signal is transmitted to the open/close control unit 139, the open/close control unit 139 drives the transfer motor 134 of the open/close driving unit 130 in the forward direction. Then, the transfer screw 132 of the opening/closing drive 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 open 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 that pushes the first connection part 111 away from the window frame 12 and pushes the first connection part 111 By this, the second connection portion 115 and the third connection portion 117 are also pushed away from the window frame 12. At this time, the opening/closing angle θ1 between the first link 112 and the second link 113 based on the first connection part 111 becomes a state of an acute angle less than 90 degrees, and the second connection part 115 and the second 3 The distance between the connection parts 117 becomes 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 window 14 is moved away from the window frame 12 by the force pushed by the 1 link 112, the second link 113, the first connecting link 114, and the second connecting link 116. (10) is opened. In this case, by discharging the smoke generated by the fire inside the building through the casement 10 to the outside, it is possible to prevent damage due to the smoke.

On the other hand, if it is determined that opening of the casement 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 is a transfer screw 132 Rotate in the reverse direction.

When the transfer screw 132 is rotated in the reverse direction, the transfer screw 132 forcibly transfers the first moving member 121 and the second moving member 125 in a closing direction, that is, in a direction closer to each other. As the first moving member 121 and the second moving member 125 move in the closing direction, when the first moving member 121 and the second moving member 125 are separated from each other, the first link 112 and the second moving member 125 The second link 113, the first connecting link 114, and the second connecting link 116 pull the window 14 in a direction that approaches the window frame 12. Then, the first link 112, the second link 113, the first connection link 114, and the second connection link 116 is 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 connection portions 117 is also increased.

Therefore, when the first moving member 121 and the second moving member 125 are moved in a direction away from each other, the first connecting portion 111, the second connecting portion 115, and the third connecting portion 117 The window 14 is moved in a direction closer to the window frame 12 by the pulling force of the link 112, the second link 113, the first connecting link 114, and the second connecting link 116, (10) is closed.

As described above, the first link 112 and the second link 113 are cross-coupled to form a first connection part 111 and a first connection to each of the first link 112 and the second link 113 As the link 114 and the second connecting link 116 are connected to form the second connecting portion 115 and the third connecting portion 117, the first link 112 and the second link are opened and closed when the casement 10 is opened and closed. The operating 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 When opening and closing the casement window 10 even in the closed state of the casement window 10 by the first link 112, the second link 113, the first connection link 114, and the second connection link 116 It transmits the operating force in the direction of opening)
