Description

Casement Window Opening and Closing Device {OPENING AND SHUTTING DEVICE FOR WINDOW}

The present invention relates to a casement window opening and closing device, and more particularly, to provide a case of opening and closing the casement window installed in the smoke control area to be opened and closed, as well as to provide an improved opening and closing device to quickly and automatically close in the event of a fire.

In general, in case of windows installed in the area connected to the evacuation stairs or in the smoke control area such as the evacuation stairs, close the window promptly in case of fire to prevent smoke from entering the smoke control area so that people can evacuate safely. It is prescribed.

As mentioned above, a typical window installed in the smoke control area of a residential or commercial building connects the upper side of the window frame with a hinge, and the lower part is opened at a predetermined angle in the outward direction of the window frame, and the opening angle of the window is usually 18. The range of -25 ° is common, and if it is opened too much, it is excluded due to fear of safety accidents such as falling from a high floor.

A device for automatically opening and closing the casement window as described above has been developed and used in the past, the applicant of the present application has also previously applied for a patent application (No. 2012-40912) under the name "casement window opening and closing device" Looking through 6 is as follows.

The casement door automatic opening and closing device (1) to which the prior art is applied has a door closer (2) therein and installs a case (3) on the window frame.

The door closer (2) operating shaft (4) is provided with an opening and closing means (5) to open and close the hearing freely by performing a circular motion according to the movement of the window to be opened and closed, the opening and closing means (5) is the operating shaft ( The upper part and one end of the 4) is connected to the operating lever (6) for performing the linear movement necessary for opening and closing the window, and consists of an operating link (7) connected to the operating lever (6) and fixed to the window.

The stopper 8 is fixed to the lower end of the operating shaft 4 and is configured as a stopper 8 for continuing the stopped state. The stopper of the stopper is released by the means 9 so that the window opened by the operating force of the door closer can be closed.

The actuating link 7 includes an inner link 10 connected to the actuating lever 6, an outlink 12 connected to the bracket 11 fixed to the window, and the inner link 10 and the outlink 10. Middle link 13 to connect the (12), the inner link 10 is coupled to the operating hole formed in the operating lever 6, the slider 15 is fixed to the sliding movement along the operating hole It is configured to include.

In the prior art as described above, when the operation link opens the window, the inner link is pulled outward, and when closing, the actuating lever does not maintain parallel with the window frame because the inner link is pushed inward. The phenomenon of being pushed or biased outwards (left direction on the drawing) occurs.

Of course, the inner link is provided with a slider to slide with the operating hole of the operating lever, but when instantaneous force is transmitted, the sliding does not occur smoothly, and thus occurs smoothly. It becomes difficult to guarantee.

And, in order to close the window completely, the operating lever does not keep in line with the center line of the case installed in the window frame, and is in a state of entering into the inner side (indoor direction). As a result, it concentrates on the connection point of the slide coupled to the inner link.

As a result, when the window is opened or closed, the force concentrated at the connection point of the slide is not distributed in all directions through the slide, which causes a jamming operation and also prevents smooth operation.

In addition, the connecting position CP for connecting the inner link, the middle link and the out link is the same, and the connecting position CP and the horizontal center SP of the slider do not coincide, and the slider horizontal center SP is further. Because of the low position, the inner link that connects the slider is lifted when the actual window is opened and closed in an arc shape.

If the inner link is lifted as described above, the inner link, the slider, and the operating lever are adversely affected. Therefore, there is no play in the repeated operation for a long time, and as a result, the operation of the inner link becomes impossible due to the dropping of parts. There are many problems, such as becoming difficult to achieve the purpose.

In the present invention, to solve the problems described above, the door closer provided in the box-type case installed on the window frame and the door closer is connected to the operating shaft to perform the circular motion required for opening and closing the window An opening / closing means comprising an operating lever, an operating link connected to the operating lever to perform an arc motion according to the movement of the window opened and closed, a stopper fixed to the lower end of the operating shaft to stop the open window, and the case inside A casement door opening and closing device for closing a window opened by the operating force of the door closer by releasing the stopper by the release means installed in the detecting means for detecting the fire;

The inner link constituting the actuating link is a link body provided in an a shape or a T shape so as to evenly distribute the load conducted from the window while always being horizontal with the window, and formed at the center of the thickness direction of the link body. A lever slot, a slider freely coupled to the lever slot, and a slider coupled to an operation hole formed in the operation lever, and the slider has a size protruding more than both sides of the link body to facilitate load distribution. To configure;

Under normal conditions, the user can open and close the window freely, and if a fire breaks out while the window is open, the door is automatically closed automatically to prevent smoke or flame from spreading to the smoke or evacuation area, thus ensuring safe escape. Achieve goals that can help.

The present invention improves the operation link constituting the casement opening and closing device to open and close the casement window to maintain the position lower than the closed state at the maximum opening and draw a circular arc, as well as automatic in case of fire In the process of closing the system, it provides smooth operability to prevent the inflow of flames and smoke into the smoke control area or evacuation area, enabling safe evacuation, thereby eliminating the risk of safety accidents, It is invention which has various effects, such as being able to raise.

The conventional casement window opening and closing device 100 has a conventional door closer inside a box-type case 102 installed on the window frame 101, and has a window frame above the operating shaft 103 of the door closer. It is connected to the window 104 coupled to the 101 to connect the opening and closing means 110 to open and close the window 104 freely.

A stopper 106 is fixed to a lower end of the operating shaft 103 to maintain the open window 104 in a stationary state, and the stopper 106 is installed inside the case 102 to detect a fire. It is configured to release the stop state by the release means 107 actuated by the means to close and close the window 104 opened by the operating force of the door closer.

The opening and closing means 110, the upper and one end of the operating shaft 103 is connected to the operating lever 111 for performing the circular motion required for opening and closing the window 104, the operating lever 111 is coupled to the window ( It is composed of an operation link 115 for performing a circular motion along the movement of the window 104 is fixed to the lower end of the 104 and opened and closed in an arc shape.

In the present invention, it is characterized in that to ensure a smooth operability by structurally improving the operation link (115).

The operation link 115 to which the technique of the present invention is applied includes an inner link 116 connected to the operating lever 111 and an out link 118 and an inner link connected to the bracket 117 fixed to the window 104. The middle link 119 connects the 116 and the outlink 118.

The inner link 116, the out link 118, and the middle link 119 are connected by hinge pins so that the middle link 119 is connected to the inner link 116 and the out link when the window 104 is opened and closed in an arc shape. 119) to correspond to the inner link 116, the inner link 116 is coupled to the operating hole 113 formed in the operating lever 111 is coupled to the slider 120 that can slide along the operating hole 113. do.

The inner link 116 is not shown in the a shape or the figure when viewed in plan view, but the T-shape operating lever 111 to maintain a completely closed state of the window 104 is formed in the case ( The inner link 116 is always horizontal (parallel) with the window 104 even when the inner link 116 rotates inward (in the interior direction of the building) with respect to the center P of the 102 and is in an acute angle (a) state. The load conducted from) can be distributed evenly.

The inner link 116 is formed with a lever slot 122 at the center of the thickness (T) direction of the link body 121 is provided in the a-shape or T shape, the slider 120 in the lever slot 122 Combining the movement freely to be coupled to the operating hole 113 formed in the operating lever 111.

The lever slot 122 is formed in a size that does not interfere or interfere with the operation lever 111 in the opening and closing operation of the window 104, the slider 120 is a link body to facilitate load distribution It is preferable to have a size that protrudes more than both sides of the (121).

The connection point P1 of the inner link 116 and the middle link 119 and the center P2 of the thickness direction of the slider 120 are maintained in the same height (position) to open and close the window 104. The load may be properly transferred to the slider 120 through the inner link 116.

The connection point P3 of the outlink 118 and the middle link 119 is located at a higher position in the closed state of the window 104 than the connection point P1 of the inner link 116 and the middle link 119. In the open state, the window 104 is positioned at a position lower than the connection point P1 between the inner link 116 and the middle link 119 in the closed state due to the characteristic of the window being opened downward in an arc shape. The force to be closed cancels the conduction to the actuating lever 111 so that the stopper 106 can help keep the window 104 open.

The middle link 119 is provided with at least one connection hole 125 for connecting with the outlink 118 to facilitate the operation link 115 while corresponding to the difference in the size of the window frame 101 and the window 104. So that you can connect

In the present invention, the stopper 106 is also improved to prevent the window 104 from being caught and stopped in the process of opening and closing the window 104 by maintaining a constant opening force from the beginning to the maximum opening position.

The stopper 106 has a fan-shaped stopper body 131 as a whole having a circular arc shape in contact with the stop ball 130 constituting the releasing means 107. Among the outer surfaces of the stopper body 131. A stop groove 132 is formed in the maximum open position of the window 104 to maintain the open state by the stop ball 130, and otherwise, an arc-shaped slide surface 133 is formed to stop the ball 130. ) To be always in contact with

Looking at the operating state of the casement window opening and closing device 100 applied the technology of the present invention as described above are as follows.

Initially, when the window 104 is viewed in a closed state, when the user wants to open the window, when the user grabs the handle of the window 104 and rotates, the window is normally opened as if the window is opened.

In this case, the door closer does not interfere with the opening of the window 104 because the door closer generates a force so that it can be easily closed only when the door is closed without a resistance as in the case of opening a general door.

When opening the window 104 as described above, the operating lever 111 coupled to the operating shaft 104 exposed to the upper portion of the case 102 performs an arc motion in the opening direction of the window 104, the operating shaft When the stopper 106 fixed to the bottom of the 104 is also rotated to reach the set position of the window, the stopper 106 can cooperate with the release means 107 to maintain the open state continuously.

In addition, when the actuating lever 111 performs the circular motion, the actuating link 115 connected to the actuating lever 111 is a circular arc drawn by the window 104 based on the window frame 101 with a linear motion in the opening direction. It has the same mobility as exercise.

In this process, the slider 120 fixed to the inner link 116 constituting the actuating link 115 slides from the inner position to the outer position of the actuating hole 113 formed in the actuating lever 111, thereby actuating the link 115. ) Will not interfere with the linear movement.

And, it is possible to open the operation link 115 while drawing a circular arc in a linear motion, the inner link 116 is connected to the operating lever 111 and the out link 118 and the window 104 The middle link 119 is connected to the bracket 117 and the middle link 119 is connected between the inner and the outlinks 116 and 118. There is no problem in drawing.

When the user wants to close the window in such a state, when the user grasps the handle of the window 104 and pulls it, the stopper 106 and the release means 107 overcome the force of keeping the open state and the window 104 is closed. You lose.

As such, when the window 104 is closed, the actuating lever 111 simultaneously pulls the actuating link 115 with the circular motion of the actuating lever 111. In this process, the actuating hole 113 formed in the actuating lever 111 is formed. Slider 120 in the outer position of the) will be sliding to the inner position, and the window 104 is in the initial position when fully closed.

In addition, when a fire occurs in a state where the window 104 is opened, when a fire is detected by the fire detection means that a fire has occurred, the release means 107 releases the stopper 106 so that the door closer is always Since the force is generated in the closing direction, the operating shaft 104 rotates in the closing direction by the force, the stopper 106 connected with the operating shaft 104 rotates in the release direction, and the operating lever 111 also closes. Pulling the operation link 115 while rotating in the direction is to close the naturally open window (104).

In the process of opening and closing the window as described above, the window 104 is opened and closed because the center P2 of the thickness direction of the slider 120 and the connection point P1 of the inner link 116 and the middle link 119 are at the same position. In this process, the force transmitted is correctly transmitted to the center of the slider 120, and evenly distributed to the entire inner link 116 and the slider 120 received, so that the biased to any one of the slider 120, the operating lever ( The phenomenon that is caught in the operation hole 113 of the 111 can be excluded.

Particularly, in the case of the slider 120, the window 120 and the door closer are further protruded on both sides of the inner link 116 even when the slider 120 is inserted into the lever slot 122 of the inner link 116. I receive my closing force and help to increase dispersion.

The connection point P1 of the inner link 116 and the middle link 119 and the thickness center P2 of the slider 120 are horizontally moved in the opening and closing direction of the window 104 regardless of opening or closing of the window 104. However, the position is not variable in the vertical direction.

In addition, the connection point P3 of the middle link 119 and the outlink 118 is connected to the connection point P1 of the inner link 116 and the middle link 119 and the slider 120 while the window 104 is closed. The closing force of the window 104 and the door closer is sufficiently transmitted to the slider 120 and the operating lever 111 through the inner link 116 at a position higher than the center in the thickness direction P2.

In addition, when the window 104 is opened, the connection point P3 of the middle link 119 and the outlink 118 is the thickness of the connection point P1 of the inner link 116 and the middle link 119 and the slider 120. Since the position lower than the center of the direction (P2), the force to close the window 104 and the closing force of the door closer is not transmitted directly to the inner link 116, so that the stopper 106 is open window It will help to stop (104).

In the process of opening and closing the window 104 as described above, in a state in which the window 104 is closed, the stop ball 130 is connected to one side of the stopper body 131 on the sliding surface 133 (the opposite position of the stop groove). When the window 104 is opened in this state, the stopper body 131 is rotated in accordance with the movement of the operating lever 111 to be fixed to the operating shaft 103.

Then, the stop ball 130 slides along the slide surface 133, and when the window 104 reaches the maximum opening position, the stop ball 130 is inserted into the stop groove 132 formed in the stopper body 131. It remains open.

When the fire is detected, the fire detection means is applied to the release means 107 that the fire state because the stop ball 130 is retracted out of the stop groove 132, the operating shaft 103 is rotated by the closing force of the door closer And, the stopper 106 fixed to the working shaft 103 is also not limited by the stop ball 130, so that the window 104 can be closed.

In the present invention, when the window 104 is opened and closed, the stop ball 130 constituting the stopper 106 is in contact with the sliding surface 133 of the stopper body 131, so that the stop groove 132 is not connected to the stop groove 132. Always maintain a constant force until combined to always maintain a constant opening force from the beginning to the maximum opening position to prevent the phenomenon such as being caught in the middle of opening and closing the window.

The present invention is to open and close the window freely in the usual state, if the fire occurs in the open state of the window quickly closes the open window automatically to prevent smoke or flame spread to the smoke or evacuation area. Has the advantage of helping to escape safely.
