Description

Technology Field

[0001] The present invention relates to a device capable of automatically opening and closing a window using a cylinder, and more specifically, to an automatic opening and closing device for sliding windows capable of simultaneously opening and closing multiple windows with a single operation, and achieving smoother operation by arbitrarily adjusting the height of the movable bar to achieve a level. Background Technology

[0002] Generally, most buildings are equipped with multiple windows for ventilation, soundproofing, and thermal insulation, and these windows are installed so that they can be opened and closed as needed.

[0003] In cases where the windows are installed at a high position out of reach of human hands, where the windows are large and it is difficult to open and close them using only human strength, where the opening and closing of the windows is programmed by factory automation equipment, or where ventilation and temperature control must be continuously managed such as in livestock barns, additional opening and closing devices are installed to enable automatic opening and closing using power such as motors or cylinders.

[0004] In particular, since factories, performance halls, gymnasiums, greenhouses, warehouses, and livestock barns have high ceilings and windows are installed at very high positions requiring the use of ladders or cranes, installing and operating a separate opening and closing device is convenient and effective for management; similarly, convenience is enhanced in general households as well by enabling mechanical opening and closing of windows.

[0006] Conventionally, such opening and closing devices are known as Korean Patent Publication No. 10-1993-0003438 "Opening and closing device for high-rise windows," Registered Utility Model Publication No. 20-0246982 "Opening and closing device for windows using a pneumatic system," Published Patent Publication No. 10-2004-0095066 "Automatic opening and closing device for factory ventilation windows," and No. 10-2007-0009951 "Pneumatic automatic opening and closing system for windows."

[0007] Each of the above-described structures applies a configuration principle in which either the body or the piston rod of a pneumatic cylinder is fixed to a window frame using a bracket, and the other end of the pneumatic cylinder is fixed to a window frame forming a casement window using a bracket, thereby opening and closing the window according to the stroke of the piston rod driven by pneumatic pressure.

[0009] These window opening and closing devices are applied to casement windows in which the window is opened and closed by the stroke of a cylinder while one side of the window frame is connected to the frame by a hinge structure, and thus there are difficulties in applying them to sliding windows that support the window frame on a rail formed on the frame to slide.

[0010] In other words, since the opening and closing mechanism of conventional casement windows is structured such that a cylinder-type mechanism bears the load applied from the window and transmits it to the window frame, it requires durability to accommodate loads such as wind pressure or the weight of the window. Furthermore, the coupling position and angle of the cylinder must be precisely selected to properly adjust the opening amount and maintain the reliability of the opening and closing operation.

[0011] Since sliding windows open and close by moving along rails while supported by the window frame, factors such as the weight of the window or wind pressure exerted through it have almost no effect on the configuration of the opening and closing mechanism. Furthermore, because the window opens and closes with only a small force generated by the rolling motion of the rollers and rails attached to the frame, driving force is not a primary consideration.

[0013] However, in conventional technology, the coupling position of the cylinder must be precisely selected to properly adjust the opening and closing amount and maintain the reliability of opening and closing; additional pressure exceeding the allowable pressure must be properly blocked during the full opening and closing stage of the window; and a structure is required to properly relieve localized loads that cause trouble at the joints between components and reduce durability, which are caused by factors such as the window warping or misalignment of the axis of motion between the window frame and the window frame support point.

[0014] In addition, since sliding windows are mostly installed within reach of people, aesthetics must be considered, they must not be dangerous to users, and multiple windows must be able to be opened and closed simultaneously with a single operation. The problem to be solved

[0015] The present invention aims to solve the aforementioned problems by providing an automatic opening and closing device for sliding windows that is improved to allow multiple windows to be connected to a movable bar that can move left and right, thereby enabling simultaneous opening and closing by a single operation.

[0016] In addition, another objective of the present invention is to provide an automatic opening and closing device for sliding windows that is improved so that the height can be freely adjusted by fixing the movable bar by a magnet, thereby enabling smoother operation through accurate leveling. means of solving the problem

[0017] The automatic opening and closing device for a sliding window according to the present invention comprises a plurality of vertical frames installed at left-right intervals on the front of an interior panel, a window installed between the vertical frames, a movable bar horizontally connected to the front of the vertical frames to allow for left-right movement, and a connecting bar connected between the movable bar and the window. In this automatic opening and closing device for a sliding window, a rod of a cylinder fixed to the vertical frame is connected to the movable bar, and the movable bar moves left and right by the operation of the rod to simultaneously open and close a plurality of windows. A fixing member fixed to the window is connected to one side of the connecting bar, and a housing through which the movable bar passes and is fixed is connected to the other side of the connecting bar, and a cover is connected to the housing. The movable bar is installed by penetrating the inner side of a guide member connected to the vertical frame by a magnet, and a roller on which the movable bar rests is connected to the inner side of the guide member so as to be rotatable. The rotation axis of the roller is connected to a magnet, and the magnet adjusts the height of the guide member so that the movable bar can be connected horizontally. The cylinder is characterized by being adjustable, and operating by the operation of the control unit or by being operated automatically by a temperature sensor. Effects of the invention

[0018] According to the automatic opening and closing device for sliding windows of the present invention, a movable bar horizontally coupled to a vertical frame is configured to move left and right by the operation of a cylinder, and since the movable bar and a plurality of windows are connected by a connecting bar, a plurality of windows can be opened and closed simultaneously by a single operation, thus having the advantage of being very convenient to use.

[0019] In addition, the present invention is configured to fix the movable bar by means of a magnet, thereby allowing for precise adjustment of the movable bar's horizontal level. Furthermore, since the height can be easily adjusted at any time even when the metal movable bar expands or contracts, it offers the effect of making maintenance more convenient.

[0020] In addition, since the movable bar firmly supports the window, the present invention also has the effect of preventing the window from becoming detached due to changes in the external environment, such as strong winds or earthquakes. Brief explanation of the drawing

[0022] A preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0023] The automatic opening and closing device for sliding windows of the present invention is configured to allow multiple windows (3) to be opened and closed simultaneously with a single operation by installing it in a place where the ceiling and windows (3) are formed high, such as a factory, a performance hall, a gymnasium, a greenhouse, a warehouse, a livestock barn, etc., as shown in FIG. 1.

[0024] FIG. 1 shows a factory made of prefabricated buildings as an example of an embodiment, wherein the window (3) is installed in a window frame (2) attached to an interior panel (1) forming the interior of the building, and a plurality of vertical frames (4) are installed on the front of the interior panel (1) at intervals from left to right.

[0025] The above vertical frame (4) is made of a metal beam, and generally a window (3) is installed between the vertical frames (4), and a horizontal frame (5) is connected to the upper side of the vertical frame (4) as shown in FIG. 2.

[0027] As shown in FIG. 3, a moving bar (10) for opening and closing a plurality of windows (3) simultaneously is installed horizontally on the front of the vertical frame (4) by means of a magnet (40) and a guide member (50) and configured to move left and right, and a connecting bar (20) is connected between the windows (3) and the moving bar (10) as shown in FIG. 4.

[0028] The above connecting bar (20) is formed with a length corresponding to the width of the vertical frame (4) and serves to connect the window (3) and the moving bar (10), thereby enabling the moving bar (10) and the window to move left and right simultaneously.

[0029] A fixing member (21) is attached to one side of the above connecting bar (20) and is fixed to the window (3) by a bolt, and a housing (30) is attached to the other side of the connecting bar (20) and is connected to the moving bar (10).

[0030] The above fixed member (21) and housing (30) are fixed to the connecting bar (20) by welding, and the housing (30) is bent into a flange shape as shown in FIG. 5 so that a moving bar (10) is connected to the inside, and the moving bar (10) is fixed by a cover (31) so that the connecting bar (20) and the moving bar (10) can move simultaneously and are firmly fixed.

[0032] Meanwhile, a moving bar (10) that is horizontally connected to a plurality of vertical frames (4) is connected by a magnet (40) as shown in FIG. 6, and a guide member (50) with an open bottom surface is connected to the front of the magnet (40) by a bolt (B), and a roller (51) is connected to the inside of the guide member (50) so that it can rotate around the bolt (B) as a central axis.

[0033] A moving bar (10) is seated on the upper side of the roller (51) and moves left and right inside the guide member (50), and at this time, smooth movement is achieved by the rotation of the roller (51) and the guide member (50).

[0034] In this invention, a moving bar (10) extending to the left and right is installed precisely horizontally, thereby enabling multiple windows (3) to be opened and closed simultaneously by smooth movement to the left and right, and is coupled to a vertical frame (4) using a magnet (40).

[0035] Since the magnet (40) can be installed by arbitrarily adjusting the connection height of the guide member (50), the movable bar (10) can be fixed by finely adjusting the height so that it is precisely horizontal without one side bending due to the load, and it is more convenient because the height can be adjusted at any time without separating the guide member (50) even if the movable bar (10) expands or contracts due to a temperature difference and a part of it is bent.

[0037] Meanwhile, in order to move the moving bar (10) left and right, as shown in FIGS. 2 and FIGS. 7, a pneumatic cylinder (60) is used as one embodiment, but is not limited thereto and a hydraulic or electric cylinder may also be used.

[0038] The above cylinder (60) is coupled to the vertical frame (4) by a coupling member (62), and the rod (61) of the cylinder (60) is connected to the moving bar (10) by a bracket (63), and the rod (61) moves the moving bar (10) left and right by being pulled out or pulled in by the pressure of air supplied through the input hose (72).

[0039] The input hose (72) is connected to an operating unit (70) equipped with a lever for controlling air as shown in FIG. 2, and an air hose (71) for supplying air is connected to the operating unit (70).

[0040] The present invention is not limited to operation by the control unit (70), but may also be configured to operate automatically by a temperature sensor.

[0042] As shown in FIG. 8, the automatic opening and closing device for sliding windows of the present invention configured in this manner allows the rod (61) to be pulled out when air is supplied through the air hose (71), and accordingly, the moving bar (10) and the connecting bar (20) move so that a plurality of windows (3) can be opened simultaneously, and the windows (3) can be closed by moving to the right through the retraction of the rod (61).

[0043] Accordingly, the present invention is configured so that a moving bar (10) horizontally coupled to a vertical frame can move left and right by the operation of a cylinder (60), and since the moving bar (10) and a plurality of windows (3) are connected by a connecting bar (20), a plurality of windows can be opened and closed simultaneously by a single operation, thus having the advantage of being very convenient to use.

[0044] In addition, by configuring the movable bar (10) to be fixed by a magnet (40), the horizontal level of the movable bar (10) can be finely adjusted, and the height can be easily adjusted at any time even if the metal movable bar (10) expands or contracts, thus making maintenance more convenient.
