Description

AUTOMATIC WINDOW OPENING AND CLOSING DEVICE USING DRIVING ROLLER AND WINDOW INCLUDING SAME

The present invention relates to an automatically opening and closing window and, more specifically, to an automatic opening and closing device for automatically opening or closing a window unit by using a driving roller which rotate by the rotation force transmitted from a motor, and a window including the same.

In general, a window serves as a wall member for separating an indoor space from the outside and simultaneously introduces the sunlight and fresh air from the outside into the indoor space so as to enable the indoor ventilation.

The windows are classified into various kinds according to the materials thereof or the opening methods thereof. According to the opening methods, the windows are typically divided into a tilt and turn type window capable of being fully opened or closed inwards, a lift slide window capable of being lifted upwards from a bottom rail and moving using a hardware having a lifting function at the time of opening or closing, and the like.

Among these, the lift slide window includes a fixed window unit and movable window units at either one or both sides of the fixed window to be opened or closed.

Such a lift slide window has been disclosed in Korean patent laid-open publication No. 10-2006-0025389.

More specifically, the lift slide window includes a basic structure, in which a fixed window unit is provided to a window frame and a movable window unit moves along rails, which are provided at the upper and lower portions of the window frame, in the right and left directions so as to be opened or closed, wherein a hardware is further provided to the basic structure such that the hardware secures the locking and airtightness of the window units by moving the movable window unit in the vertical or horizontal direction.

According to the lift slide window in the above structure, if a handle is turned so as to open the window, the movable window unit is lifted upwards from the bottom rail by a predetermined height through the operation of the hardware which includes a lifting means and, in this state, the movable window unit horizontally moves, thereby being opened in a silent and smooth manner.

Further, in the closed state of the movable window unit, the sash of the movable window unit comes in close contact with the bottom rail and thus can secure the airtightness, watertightness, insulation performance and the like.

The window is applied to and used in a relatively large-scaled window for a living room, a patio and the like. The window, however, has a disadvantage that the opening and closing of the window requires a large force because the window should be manually operated in spite of the large size thereof. In order to solve this problem, Korean patent registration No. 10-0915952 discloses an automatic opening and closing device for sliding the window along a screw shaft which rotates by a driving means so as to automatically open or close the window.

However, the prior art automatic window opening and closing device still has a disadvantage that, because of the structure thereof, the prior art automatic window opening and closing device cannot be applied to a lift slide window in which a window unit is lifted upwards from the bottom rail so as to move at the time of opening and closing even though the prior art automatic window opening and closing device can be applied to a simple sliding window in which the window unit simply reciprocates by sliding in the horizontal direction.

Therefore, a new automatic opening and closing device is required to be applied to a general sliding window which is opened or closed by sliding in the horizontally lengthwise direction as well as the lift slide window in which the window unit moves upwards by a predetermined distance at the time of opening and closing.

The present invention has been proposed based on the above technical background, satisfies the above-mentioned technical demands, and provides technical parts that those skilled in the art cannot easily invent or make.

Accordingly, the present invention has been made in an effort to solve the above-mentioned problems occurring in the prior arts, and it is an objective of the present invention to provide an automatic opening and closing device having a driving rollers, wherein the driving roller rotate by the rotation force transmitted from a motor so as to automatically open or close the window unit.

It is another objective of the present invention to provide a lift slide window including an automatic opening and closing device having a driving rollers, wherein the opening and closing device having a driving roller is applied to the lift slide window of which a movable window unit is lifted upwards from the bottom rail so as to move.

To achieve the above objectives, in an automatic window opening and closing device for automatically opening or closing the window slidingly coupled to the rails of a window frame, an automatic window opening and closing device, according to the present invention, comprises: a driving motor provided to any one of at least one pair of window units; and a driving roller rotating by the power transmitted from the driving motor and provided to come into contact with one surface of an adjacent window unit at the outer peripheral surface thereof such that the adjacent window unit can be slidingly opened or closed.

In an automatic window opening and closing device for automatically opening or closing a lift sliding window slidingly coupled to the rails of a window frame, the automatic window opening and closing device, according to another preferred embodiment of the present invention, comprises: a driving motor provided to any one of at least one pair of window units; and a driving roller provided, to rotate, to the same axial line with a vertical shaft which rotates by the power transmitted from the driving motor and coming into contact with one surface of an adjacent lift slide window unit so as to slidingly open or close the window unit, wherein the driving roller is coupled so as to slidingly move along the axial direction of the vertical shaft via a sliding means such that the driving roller prevents the sliding friction between the lift slide window unit which is lifted by a predetermined height from the bottom rail and the driving roller at the time of the opening or closing thereof.

In an automatic window opening and closing device for automatically opening or closing a lift sliding window slidingly coupled to the rails of a window frame, an automatic window opening and closing device, according to still another preferred embodiment of the present invention, comprises: a driving motor provided to any one of at least one pair of window units; and a driving roller provided to the same axial line with a vertical shaft which rotates by the power transmitted from the driving motor so as to integrally rotate with the vertical shaft and coming into contact with one surface of an adjacent lift slide window unit so as to slidingly open or close the window unit, wherein a sliding means is provided to one surface of the lift slide window unit which comes into contact with the driving roller and prevents the sliding friction between the driving roller and the window unit which is lifted by a predetermined height from the bottom rail at the time of the opening or closing thereof.

A lift slide window including an automatic window opening and closing device, comprises: a window frame provided with rails therein; a lift slide window unit slidingly coupled to the rail and automatically lifting or lowering with respect to the bottom rail through a lifting module at the time of opening or closing operation; and any one of a plurality of automatic window opening and closing devices to be provided to the window frame and automatically opening or closing a lifted window unit.

The present invention according to the above mentioned structure, can readily open or close the window by applying an automatic window opening and closing device to a general sliding window to be slidingly opened or closed in the horizontally lengthwise direction as well as a lift slide window which moves a predetermined distance in the vertical direction at the time of opening or closing the window.

In addition, the present invention has an advantage that the automatic opening and closing device can be easily converted to a manual mode by disconnecting the connection with respect to the driving motor by operating an electronic clutch so as to open the window even when the driving part forming the automatic opening and closing device has some driving part troubles.

Hereinafter, with respect to reference signs provided to the constituent elements of the drawings, it should be noted that the same constituent elements are denoted by the same reference signs even though they are shown in different figures.

Fig. 1 is a perspective view showing a lift slide window provided with an automatic opening and closing device according to the present invention, which is viewed from the outdoor side, Fig. 2 is an expanded view of part "A" of Fig. 1, Fig. 3 is an expanded view of part "B" of Fig. 1, and Fig. 4 is a side sectional view showing the structure of the automatic opening and closing device according to the present invention.

Referring to Fig. 1, a window including an automatic window opening and closing device using a driving roller according to a preferred embodiment of the present invention includes a window frame 10, a lift slide window unit 20 slidingly coupled to the rail 11 of the window frame 10 and moving after being lifted above the rail 11 by a lifting module 200 at the time of opening or closing, and an automatic opening and closing device 100 provided to the head of the window frame 10 so as to automatically open or close the window unit 20.

The present invention will now be described in more detail with respect to the configuration thereof.

First, the automatic window opening and closing device 100 serves to automatically open or close the window unit 20, which is lifted by the lifting module 200, simply by sliding the same with a small force. This automatic opening and closing device 100 is provided to any one of at least one pair of window units 20 and slidingly opens or closes the other window unit 20, which is arranged to be adjacent to the one window unit 20, in the right and left direction.

In addition, the automatic opening and closing device 100 is provided to be received in a receiving space in a vertical member (mullion) 21 of one of the window units 20 which partially overlap each other at the time of closing, so as to avoid the exposure thereof to the outside. In addition, the window unit to which the automatic opening and closing device 100 is provided is preferably formed as a fixed window unit 20' but not limited thereto. Therefore, such a fixed window 20’ can be selectively provided to be opened or closed.

Referring to Fig. 2 and Fig. 3, the automatic opening and closing device 100 can include a driving motor 110 provided to the window unit, and a driving roller 130 provided to the same axial line with a vertical shaft 120 which is rotated by the power transmitted from the driving motor 110 so as to rotate together with the vertical shaft 120 and come into contact with one surface of an adjacent lift slide window unit 20 at the outer peripheral surface thereof so as to slidingly open or close the window unit 20.

Referring to Fig. 4, the driving roller 130 can be provided such that the outer periphery of the driving roller 130 comes into contact with any one of upper and lower horizontal members 23 which form the outer frame of the window unit 20. Herein, the present invention will be illustrated and described with reference to an embodiment as an example, in which one pair of driving rollers 130 are preferably provided to be symmetrically to each other at the upper and lower ends of the vertical member 120 and respectively come into contact with the both upper and lower horizontal members 23 of the window unit 20 so as to efficiently open or close the window unit 20.

The driving roller 130 has a concave and convex portion 130a provided in the width direction on the outer periphery thereof such that the concave and convex portion 130 can prevent the slip of the driving roller 130 when the driving roller 130 rotates, contacting the surface of the horizontal member 23. In addition, the surface of the horizontal member 23 which comes into contact with the driving roller 130 can be correspondingly provided with a slip prevention member (not shown) having a rough surface such as a sandpaper, a concave and convex portion and the like so as to prevent the slip thereof during the contact with the concave and convex portion 130a of the driving roller 130.

Referring to Fig. 5, the driving roller 130 in the above structure can be coupled to slide along the axial direction of the vertical shaft 120 through a sliding means 140. That is, the lift slide window unit 20 is lifted upwards by a predetermined height from the bottom rail 11 at the time of opening and closing, wherein the lift slide window unit 20 integrally moves together with the driving roller 130. In other words, at the time of lifting the window unit 20, the driving roller 130 which is in contact with the one surface of the horizontal member 23 simultaneously moves by a predetermined height by the sliding means 140 and thus can prevent the friction due to the slip of the window unit 20 and the driving roller 130. In the case of a structure, in which the driving roller 130 is stopped and is not lifted or lowered simultaneously with the lifting of the window unit 20, the outer periphery of the driving roller 130 is possibly worn by the repetitive lifting and lowering operations of the window unit 20.

Referring to Fig. 6, the sliding means 140 according to one embodiment of the present invention can include a protrusion part 141 in the shape of a polygonal column which protrudes in the axial direction from the end surface of the vertical shaft 120 and a coupling groove part 143 formed in a corresponding shape to the rotation shaft 131 of the driving roller 130 so as to be slidingly coupled with the protrusion part 141 in the axial direction. The driving roller 130 has a sliding shaft 133 positioned at the opposite side of the rotation shaft 131, wherein the sliding shaft 133 is slidingly coupled to a support member 121.

According to another embodiment, the sliding means 140 can include one pair of semicircular columns 145 which are correspondingly coupled with each other so as to slide in an axial direction, as shown in Fig. 7, wherein the vertical shaft 120 is cut to be divided into an upper part and a lower part and the one pair of semicircular columns 145 are respectively formed to protrude in the axial direction from thus oppositely formed upper and lower cut surfaces of the vertical shaft 120 such that the one pair of semicircular columns 145 are engaged with each other so as to integrally rotate.

Referring to Fig. 8, the divided upper and lower parts of the vertical shaft 120 are respectively coupled with bearings (not shown) so as to respectively rotate through the support members 121. Therefore, the smooth power transmission can be realized even though the vertical shaft 120 is divided.

Herein, even though the present invention is described with reference to the embodiment as an example, in which the sliding means 140 are provided to the cut and divided upper and lower parts of the vertical shaft 120 and slide in the axial direction, the present invention is not limited thereto but can be modified in various structures.

For example, as shown in Fig. 9, the sliding means 140 can be provided to one surface of the lift slide window unit 20 which comes in contact with the driving roller 130, that is, the contact portion of the horizontal member 23 on which the driving roller 130 is positioned when the window unit 20 is closed.

Herein, the sliding means 140 is preferably formed in a structure, in which the both sides of a vertical movement member 147 are coupled on rail groove parts 147a provided on one surface of the window unit 20 so as to slide in the vertical direction. In other words, at the time of lifting operation of the window unit 20, the vertical movement member 147 slidingly coupled to the rail groove parts 147a and the driving roller 130 coming into contact with the vertical movement member 147 are stopped in position and only the window unit 20 is lifted by a predetermined height t.

Referring to Fig. 10, the one surface of the window unit 20, which comes into contact with the outer periphery of the driving roller 130, and the surface of the vertical movement member 147 form the same plane surface. Therefore, after the lifting operation of the window unit 20 is finished, the driving roller 130 can open or close the window unit 20 while rotating along the lengthwise direction of the horizontal member 23.

According to another embodiment of the present invention, the sliding means 140 may include a plurality of rotation rollers 149 which are arranged on a groove part 149a provided on one surface of the horizontal member 23 of the window unit 20 in the horizontal direction, as shown in Fig. 11. That is, the plurality of rotation rollers 149 are formed in the shape of a cylinder such that the both ends of the rotation rollers 149a can rotate on the groove part 149a, wherein the plurality of rollers 149 are provided to the groove part 149a at intervals in the vertical direction. Therefore, at the time of the lifting operation of the window unit 20, the driving roller 130 coming into contact with the one surface of the window unit 20 moves in the vertical direction along the sliding means 140 formed of the plurality of rotation rollers 149 (more specifically, the driving roller 130 is stopped in position and the window unit 20 is lifted upwards by the predetermined height t) such that the friction due to the slip can be prevented. As the lifting operation is finished, the driving roller 130 slidingly opens or closes the window unit 20 in the horizontal direction while rotating by the power transmitted from the driving motor 110.

Hereinabove, the sliding means 140 according to the above various embodiments is illustrated and described with reference to the case that the sliding means 140 is positioned on the horizontal members at the upper or lower part of the window unit 20 in the drawings, but not limited thereto. That is, it should be noted that the sliding means 140 are applied to respectively correspond to the driving rollers 130 in the case that the driving rollers 130 are symmetrically provided at the upper and lower parts of the window unit 20.

Referring to Fig. 13, the automatic window opening and closing device 100 as structured above can be applied to a window having general sliding window unit. Further, the automatic window opening and closing device 100 can be preferably applied to the lift slide window, in which the window unit 20 is lifted upwards from the bottom rail so as to move at the time of opening and closing, thereby improving the airtightness and the insulation performance.

In other words, the opening and closing device 100 operates to open or close the window unit 20 in the horizontal direction after the lift slide window unit 20 is lifted upwards from the bottom rail 11. Hereinafter, the configuration and performance of such a lift slide window including the opening and closing device 100 will be described in more detail.

First, the rails 11 are provided in the lengthwise direction on the upper and lower surfaces which face to each other in the window frame 10 and coupled with at least one pair of window units 20 for the sliding opening and closing of the window units 20.

The lift slide window unit 20 (hereon, referred to as “window unit”) automatically lifts or lowers on the rail 11 by the lifting module 200 at the time of opening or closing of the window, wherein a gasket (not shown) for maintaining the airtightness is provided at the lower portion of the window unit 20 so as to come into close contact with the inner surface of the window frame 10 at the time of closing operation.

Referring to Fig. 14, the lifting module 200 can include a driving part 210, an operation rod 220 provided to move in the vertical direction by the power transmitted from the driving part 210, a connection link 230 connected to the operation rod 220 and provided at the lower corner portion of the window unit 20 so as to convert the vertical movement to the horizontal movement, a slider 240 connected to the connection link 230 and able to slide along the lengthwise direction of the bottom surface of the window unit 20 such that a guide shaft 241 provided therein operates to push up or down a slant guide elongation hole 243a of a lifting block 243 so as to lift or lower the window unit 20 with respect to the rail 11 when the driving part 210 operates, and a roller 250 rotationally provided at the lower portion of the slider 240 and placed on the rail 11.

Referring to Fig. 15, the driving part 210 includes a housing 211 provided to the indoor side of the window unit 20, a driving motor 213 fixed in the housing 211, a shaft 217 engaged with the rotation shaft 213a of the driving motor 213 through gear trains 215 so as to rotate in association with the rotation shaft 213a of the driving motor 213, and a gear module 219 connected to the shaft 217 and converting the rotation motion to the straight reciprocation motion so as to move the operation rod 220 in the vertical direction. The driving part 210 in the above structure can be wirelessly operated with a remote controller 280 for user convenience.

Referring to Fig. 16, the gear module 219 can includes a rack 219a integrally provided to the operation rod 220, and a pinion 219b coupled to the shaft 217 on the same axial line therewith. However, the present invention is not limited thereto, and a structure of a conveying nut (not shown) can be applied through modification such that the gear module 219 is slidingly coupled to, for example, a ball screw, as far as the rotation motion can be converted into the straight reciprocation motion.

In addition, the gear train 215 includes a worm 215a integrally provided to the rotation shaft 213a of the driving motor 213 and a worm gear 215b engaged with the worm 215a, thereby transmitting power.

Referring to Fig. 17, the driving part 210 can further includes a manual mode conversion means 260 for manually lifting the window frame 20 when the driving motor 213 fails. Herein, the manual mode conversion means 260 may preferably include a clutch gear 263 having a central shaft 263a coupled in a coupling hole 211a in the housing 211 so as to slide in the axial direction and engaged between the gear trains 215 so as to connect the gear trains 215 to each other while being elastically supported by an elastic spring 261, and a wrench coupling part 265 concentrically provided at one end of the shaft 217 and exposed to the outside of the housing 211.

In addition, a press button 263b for operating the clutch gear 263 can be provided to the outer peripheral surface of the housing 211. That is, the press button 263b is an essential constituent element for disconnecting the connection with respect to the driving motor 213 before manually rotating the shaft 217 with wrench W and the press button 263b can be formed in various structures.

Herein, the press button 263b can be preferably formed in a structure, in which the press button 263b is extended on the same axial line with the central shaft 263a so as to press the central shaft 263a of the clutch gear 263 such that the central shaft 263a is moved in the axial direction that the elastic spring 261 is provided so as to shortly disconnect the connection with respect to the driving motor 213.

That is, the manual mode conversion means 260 enables the manual lifting of the window unit 20, as shown in Fig. 18. Speaking more specifically, as a user presses the press button 263b, the central shaft 263a of the clutch gear 263 is pressed and moved in the axial direction where the elastic spring 261 is provided, thereby shortly disconnecting the connection with respect to the driving motor 213. After that, the user can couple a handle or a wrench W into the wrench coupling part 265 and manually rotate the handle or the wrench W, thereby manually lifting the window unit 20.

Referring to Fig. 15 again, a cover 270 can be coupled to the outer peripheral surface of the housing 211 for improving the beauty of the appearance of the driving part 210. In addition, the cover 270 can be provided with a rotation member 273 which rotates with respect to an eccentric shaft 273a serving as the center of rotation, thereby selectively exposing the wrench coupling part 265 through a through hole 271. That is, the wrench coupling part 265 is used only in the case of emergency such as the failure of the driving motor 213 with a low frequency of use. If the wrench coupling part 265 is formed in a constantly exposed structure, the wrench coupling part 265 is likely to cause malfunction due to inappropriate operation made out of the curiosity of children and to degrade the beauty of the driving part 210 due to foreign materials and the like possibly fitted therein. Therefore, it is preferable to form the wrench coupling part 265 in a normally hided structure through the rotation member 273.

Herein, the rotation member 273 can be preferably provided with a slant surface 273b for rotating with respect to the eccentric shaft 273a as the center of rotation and simultaneously coming into contact with the press button 263b so as to press the press button 263b. Therefore, the connection with respect to the driving motor 213 and the clutch gear 263 can be simultaneously disconnected by the simple operation of rotating the rotation member 273 and opening the wrench coupling part 265 to be fitted with the wrench W, thereby more simplifying the manual operation of the driving part 210.

In this case, an operation handle 273c can be provided to the surface of the rotation member 273 and protrude towards the outer peripheral surface of the cover 270 such that the operation handle 273c can readily operate the rotation member 273 to rotate.

Referring to Fig. 19 and Fig. 20, the wrench W for operating the manual mode conversion means 260 can be integrally provided to one surface of the remote controller 280 which is used at the time of opening or closing the window unit 20 such that a user can easily find and use the wrench W. This wrench W can be formed in a structure, in which the wrench W is hinge-coupled to a groove part 281 formed on the rear surface of the remote controller 280 through a hinge shaft W1 so as to be foldable in the groove part 281.

Fig. 21 is a state view of an automatic opening and closing device provided with an electronic clutch for manual/automatic mode conversion according to the present invention, and Fig. 22 is a view showing the details of part "C" of Fig. 21 and the operation state thereof.

Referring to Fig. 21, the automatic opening and closing device 100 according to the present invention can further include an electronic clutch 150 for manual/automatic mode conversion. The electronic clutch 150 operates at the same time when the window unit 20 is converted to be manually operated to be lifted, wherein the electronic clutch 150 serves to disconnect the connection between the driving motor 110 and the upper and lower driving rollers 130 such that the window unit 20 can be manually opened or closed.

Explaining in more detail with reference to Fig. 22, the automatic opening and closing device 100 drives the driving rollers 130 by rotating the vertical shaft 120 through a first spur gear 111 integrally coupled to the rotation shaft 110a of the driving motor 110 and a second spur gear 113 coupled to the vertical shaft 120.

In this case, the second spur gear 113 is in a state, in which the second spur gear 113 is coupled on the central shaft of the vertical shaft 120 and enabled to idle. In addition, the electronic clutch 150 is provided to be adjacent to the second spur gear 113 on the same axial line with the vertical shaft 120. The electronic clutch 150 is integrally coupled to the vertical shaft 120 so as to integrally rotate together with the vertical shaft 120, wherein an electromagnet (not shown) is provided to the inside of the electronic clutch 150.

Therefore, if a current is applied to the electromagnet of the electronic clutch 150, the second spur gear 113 adjacent to the electronic clutch 130 is pulled by the magnetic force of the electromagnet so as to integrally rotate together with the electronic clutch 130, thereby transmitting the power of the driving motor 110 to the driving roller 113.

To the contrary, if the current is blocked with respect to the electromagnet, the electronic clutch 150 and the second spur gear 113 separate each other and the power transmitted to the driving roller 130 from the driving motor 110 is blocked. Therefore, the smooth opening and closing operations of the window unit 20 are enabled even when the driving motor 110 or the driving part 210 fails.
