Description

  The present invention relates to a smart joinery that can automatically open and close a shoji, and more specifically, it can automatically open and close a lift sliding smart joinery, and can be manually switched to open and close, and an automatic open / close button is provided on the case. The present invention relates to a lifting device provided with an automatic / manual switching structure that can be opened and closed by a simple button operation and a smart fitting including the same.

  In general, joinery serves as a wall that separates the room from the outside, and at the same time plays a role of allowing indoor ventilation by allowing sunlight and fresh fresh air to flow in.

  Such joinery can be classified into various types according to the material or the opening method, and depending on the opening method, the tilt and turn method that can open and close the shoji largely inward, and the lift function. There is a lift sliding method in which the shoji is moved up and down on the rail when opening and closing using the above hardware.

  Among them, the lift sliding method is configured by placing a fixed window and opening one side or both sides of the fixed window. A prior application has been filed as Patent Document 1 for such lift sliding joinery.

  More specifically, the lift sliding joinery has a basic configuration including a fixed window installed on a window frame, and a shoji that is opened and closed while moving left and right along rails formed on the upper and lower portions of the window frame. In addition to this, hardware that secures airtightness by moving the lock and the shoji up and down or horizontally is installed.

  In the case of the lift sliding joinery having such a configuration, when the handle is turned to open the shoji, the shoji is lifted from the rail by a certain height through the operation of the hardware including the lifting means. The shoji is opened quietly and smoothly by moving horizontally. When the shoji is closed, the shoji and the rail are brought into close contact with each other, so that air tightness, water tightness, heat insulation and the like can be secured.

  Such lift sliding joinery may be applied with a structure that automatically lifts the joinery by operating an electric actuator. However, such a lift sliding joinery has a problem that the joinery cannot be lifted when the electric actuator fails.

  On the other hand, such fittings are used in relatively large fittings such as living rooms and balcony windows, but they must be operated manually compared to their size, requiring a lot of force when opening and closing. It becomes. Therefore, an automatic opening / closing device that can open / close the shoji through a screw shaft that is rotated by driving means so that the shoji can be opened / closed automatically has been filed as Patent Document 2.

  Recently, not only a simple opening / closing function of a joinery but also a joinery system that combines automatic opening / closing of a shoji, ventilation, a security system, etc. for the convenience of the user has been proposed.

  However, most of the automatic opening / closing devices and ventilating devices for shoji are systems that require a user to directly operate at a short distance indoors with a remote controller or the like.

  Therefore, when the user goes out, in most cases, he / she experiences inconvenience when he / she is worried about the operation of the ventilator and whether the shoji is opened or closed, or when the shoji opened in sudden rain must be closed. .

  Hereinafter, a configuration and operation of a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  Here, in adding reference numerals to the components of each drawing, only the same components are represented by the same symbols as much as possible even if they are displayed on other drawings. You have to be careful.

  FIG. 1 is a perspective view of a smart joinery according to the present invention, and FIG. 2 is an indoor side elevation view of the smart joinery according to the present invention.

  Referring to FIGS. 1 and 2, a smart joinery 1 according to a preferred embodiment of the present invention includes a window frame frame 10, a lift sliding obstacle 21 that automatically performs a lifting operation via a lifting device 600, and a lifted obstacle. And an automatic opening / closing device 100 that automatically opens and closes 21.

  The configuration of the present invention will be specifically described as follows.

  The window frame frame 10 constitutes a main outer frame of the lift sliding joinery, and has a rail along the longitudinal direction so that at least a pair of shojis 20 can be slidably opened and closed on the inner vertical contact surface. Not shown).

  Referring to FIGS. 2 and 3, the lift sliding shoji 21 is opened and closed in a horizontal direction after being automatically lifted on the rail by a lifting device 600 during the opening and closing operation. May be provided with a gasket (or mohair or the like) that keeps the airtightness in close contact with the inner surface of the window frame 10 during the closing operation.

  Specifically, the lifting device 600 includes a handle driving unit 610 and an operating rod that is installed so that the power of the handle driving unit 610 is transmitted through a gear module 630 (for example, a rack and a pinion gear) and is movable up and down. 631, a connection link 633 that is connected to the operating rod 631, is installed at the lower corner of the shoji 21 and converts vertical motion to horizontal motion, and is connected to the connection link 633, and the bottom of the shoji 21 The sliding shaft 21 is installed so as to be slidable along the longitudinal direction, and when the handle driving unit 610 is operated, the guide shaft 641 provided therein pushes up and down the inclined guide long hole 643a of the lifting block 643. And a slider 640 that moves up and down on the rail, and a lower portion of the slider 640 is rotatably provided. It may include a roller 650 which is mounted on the rail Te.

  Referring to FIG. 4, the handle driving unit 610 includes a housing 611 installed on one of the shojis 21 of at least a pair of shojis 20 that are slidably opened and closed on the window frame frame 10, and the housing 611. A drive motor 613 to be installed, a shaft 617 coupled to a rotation shaft of the drive motor 613 via a gear train 615, and a gear train 615, which are meshed between the gear train 615 and the shaft 617 and coupled to each other. A clutch gear 619 that is slidably reciprocally moved along the axial direction on the same axis line of the shaft 617 so that power can be selectively coupled, and is elastically supported on one side by an elastic member 618, and the housing A cover 621 coupled to 611.

  In this case, the cover 621 may be coupled to the housing 611 so that it can be opened and closed by sliding, or can be pivoted on one side via a hinge shaft.

  The handle H is embedded in a mounting groove 612 provided in the housing 611 and can be selectively pulled out from the mounting groove 612 when the cover 621 is separated.

  More specifically, referring to FIGS. 5 and 6, one axial surface of the clutch gear 619 is slidably coupled along the axial direction in a fitting hole 617 a of the shaft 617. And a first spindle 623 that rotates integrally with the shaft 617. In this case, since the first spindle 623 is formed in a polygonal column shape, the first spindle 623 can rotate integrally with the shaft 617 even if it is slidably coupled into the fitting hole 617a.

  Referring to FIG. 7A, on the other axial surface of the clutch gear 619, one end 625a is rotatably coupled, and the handle H is selectively attached to the other end 625b. A second spindle 625 is coupled. The other side of the second spindle 625 is slidably coupled to a shaft hole 627a of a rotation member 627 that is rotatably coupled to the housing 611, and rotates integrally with the rotation member 627.

  That is, one end 625a of the second spindle 625 is formed in a cylindrical shape and is idled with the clutch gear 619, and the other end 625b of the second spindle 625 is formed in a polygonal column shape, thereby Even if it is slidably coupled in the hole 627a, it can rotate integrally with the rotating member 627.

  The handle driving unit 610 having such a structure connects the gear train 615 and the shaft 617 while the clutch gear 619 pressurizes and moves in the other axial direction when the cover 621 is coupled.

  Referring to FIG. 7B, conversely, when the cover 621 is separated, the clutch gear 619 is moved in one axial direction by the elastic restoring force of the elastic member 618, thereby disconnecting the connection between the gear train 615 and the shaft 617. It becomes like this.

  That is, the other surface of the clutch gear 619 is provided with a fitting protrusion 619a. The fitting protrusion 619a is fitted in the fitting groove 627b provided on the contact surface of the rotating member 627 while the clutch gear 619 moves in the one axial direction by the elastic restoring force of the elastic member 618 when the cover 621 is separated. Fixed. Accordingly, the first spindle 623 and the second spindle 625 that have been disconnected in the automatic mode are connected to each other in the manual mode and can rotate together.

  Referring to FIG. 8, in the manual mode, the other end 625b of the second spindle 625 is exposed to the outside, and the handle H is fitted to the other end 625b of the exposed second spindle 625. The shaft 617 can be manually rotated.

  Referring to FIGS. 2 and 9 again, the automatic opening / closing device 100 is installed in at least one of the sliding doors 21 that is slid open / closed, and plays a role of automatically opening and closing the sliding door 21. The automatic opening / closing device 100 may be installed in the upper or lower part, or both the upper and lower parts in the summoning bowl 21a where the pair of shojis 20 are joined together. In the present invention, an example in which the automatic opening / closing device 100 is installed at the upper and lower portions in the summon bowl 21a will be shown and described.

  The automatic opening / closing device 100 includes a drive motor 110 installed in a summon 21a of a shoji 21 to be opened / closed by sliding, and one of fixed shoji 23 installed adjacent to and rotated by the power of the drive motor 110 being transmitted. And a driving roller 120 that slides and opens the shoji 21 so that the outer peripheral surface is in contact with the surface 23a.

  The automatic opening / closing device 100 may further include an electromagnetic clutch 130 that switches the shoji 21 so that it can be opened or closed manually or automatically. The electromagnetic clutch 130 is installed on a shaft 111 that connects the drive motor 110 and the drive roller 120, and selectively cuts off the power transmitted to the drive roller 120. It can be switched to manual release.

  The operation principle of the electromagnetic clutch 130 will be described in detail. The first gear 113 is integrally connected to the rotation shaft of the drive motor 110. The first gear 113 is engaged with the second gear 115 to move the shaft 111. The driving roller 120 is driven by a rotating method. At this time, the second gear 115 is coupled to the shaft 111 so as to be idle. An electromagnetic clutch 130 is coupled in parallel with the second gear 115 on the same axis of the shaft 111. The electromagnetic clutch 130 is integrally coupled with the shaft 111 and rotates, and an electromagnet (not shown) is provided inside.

  Therefore, when a current is applied to the electromagnet of the electromagnetic clutch 130, the adjacent second gear 115 is attached to the electromagnetic clutch 130 by the magnetic force and rotates integrally. Is transmitted to the driving roller 120 so that the shoji 21 can be opened and closed automatically.

  Conversely, when the current flowing through the electromagnet is interrupted, the electromagnetic clutch 130 and the second gear 115 are separated, and the power of the drive motor 110 that has been transmitted to the drive roller 120 is interrupted. Therefore, it is possible to smoothly open and close the shoji 21 at the time of a power failure or failure of the automatic opening / closing device 100.

  In this case, the first gear 113 and the second gear 115 may be spur gears, but it is preferable to use helical gears so as to reduce generated noise.

  The driving roller 120 may be formed of a rubber or urethane material so as to improve the adhesion with the shoji 23 with which the outer peripheral surface comes into contact.

  A plurality of concavo-convex grooves 121 may be formed on the outer peripheral surface of the driving roller 120 at regular intervals so that a frictional force can be applied when contacting the one surface 23 a of the shoji 23.

  In addition, on one surface 23 a of the shoji 23 that contacts the outer peripheral surface of the driving roller 120, an uneven pad 123 that engages with the uneven groove 121 is provided so as to prevent a slip phenomenon when the driving roller 120 is driven for the first time. Also good. The uneven pad 123 may be formed over the entire area along the direction in which the one surface 23a of the shoji 23 is opened or closed, but may be applied only to a predetermined section in which the driving roller 120 that has been stopped is first driven. Of course it is good.

  The automatic opening / closing device 100 further includes a safety sensor 140 so that the operation of the drive motor 110 can be immediately stopped when a person or object passing between the sliding doors 21 without being able to confirm the closing operation of the shoji 21 is detected. Can do. The safety sensor 140 may be installed at the tip of the summoning basket 23a or when the shoji 21 is closed. In the present invention, an example of the case where it is installed on the summon bowl 23a will be described.

  The smart joinery 1 according to the present invention as described above includes, in addition to the automatic opening / closing device 100, the natural ventilation unit 200, the light adjustment unit 300, the opening / closing notification unit 400, and the components 100, 200, 300, 400, 600. A control unit 500 (see FIG. 10) for controlling may be further provided.

  The natural ventilation unit 200 is installed in the shoji 20 to ventilate indoor air, and such a natural ventilation unit 200 is preferably installed in at least one of the pair of shojis 20 that is not opened and closed.

  In this case, the natural ventilation unit 200 may include a carbon dioxide sensor 210 that measures the concentration of carbon dioxide contained in room air. Accordingly, when the measured value measured by the carbon dioxide sensor 210 exceeds the reference value, the natural ventilation unit 200 can be automatically activated.

  In this case, with respect to the ventilator for joinery used for the natural ventilation unit 200, the Korean Patent No. 10-1274838, the registered Patent No. 10-1256771, the registered Patent No. 10- 1265564, registered patent No. 10-1301811, registered patent No. 10-1293852, registered patent No. 10-1307645, registered patent No. 10-1433437, registered patent No. 10-12938646, registered patent No. 10-129365 , Registered patent No. 10-1330447, registered patent No. 10-1252906, registered patent No. 10-1272994, registered patent No. 10-13338547, registered patent No. 10-1273019, registered patent No. 10-293802, registered Patent No. 10-1263991 and Registered Patent No. 10-1 It can be used by applying one of the No. 54413. Of course, it is not limited to this, You may apply and use the ventilation apparatus generally used for joinery. A detailed description of the operating principle of such a ventilator for joinery will be omitted.

  The light adjusting unit 300 is installed on a part or the whole of the glass provided in the shoji 20 and plays a role of switching the light transmittance of the glass to a transparent or opaque state. Usually, “magic glass” is used. Is also called.

  The magic glass used in the light adjusting unit 300 has a bonded glass structure in which an ITO film and a liquid crystal are put together between two glasses and bonded together. In such a light control unit, by applying a voltage to the magic glass, the arrangement of molecules between the ITO films can be instantaneously switched from an opaque state to a transparent state. Changes can be produced freely.

  When no voltage is applied, the liquid crystal expressed as rod-like molecules is aligned along the inner wall of the capsule. The light incident on the magic glass in this state is refracted on the surface or inside of the capsule due to the difference in refractive index between the polymer and the liquid crystal and the birefringence of the liquid crystal. As a result, the light can not travel straight but scatters and appears opaque.

  When a voltage is applied, the liquid crystal molecules are arranged in a direction perpendicular to the electrodes due to the property of becoming parallel to the direction in which the voltage is applied. In such an arrangement, if the liquid crystal has a refractive index that matches the refractive index of the polymer, the liquid crystal is the same as that without the capsule interface, and light travels straight without being scattered. Therefore, the magic glass looks transparent.

  The light adjusting unit 300 having the structure as described above is applied to the entire glass of the shoji 20 or is divided into a plurality of parts along the top, bottom, left and right directions of the shoji 20 and selectively in a transparent / opaque state. Control is possible.

  The opening / closing notification unit 400 includes a detection sensor 410 that is installed in the joinery 1 and detects in real time whether the shoji 21 has been opened or closed.

  In this case, the detection sensor 410 includes at least a pair of magnetic sensors that are attached to the sliding frame 21 and the window frame 10 so as to correspond to each other and detect whether the sliding screen 21 is opened or closed. May be.

  Specifically, the detection sensor 410 may be installed in a manner embedded in the upper part of the shoji 21 to be opened and closed and the contact surface of the window frame frame 10 corresponding thereto. Of course, the present invention is not limited to this, and the present invention can be applied with various changes as long as it can easily detect whether the shoji 21 is forcibly opened or closed.

  The control unit 500 performs individual / integrated control of the functions 100, 200, 300, 400, 600 using the user's wireless communication terminal 510 regardless of time and place, and wireless communication. The state of the various components is displayed on the display window of the terminal 510 in real time.

  Specifically, the controller 500 uses wireless communication and is connected to an application of the terminal 510 via the Internet after a wireless signal is transmitted to a gateway.

  In this case, the wireless communication preferably uses an RF communication method. Of course, the present invention is not limited to this, and can be used by applying zigbee wireless communication that supports short-range communication. For reference, ZigBee wireless communication is one of the IEEE 802.15.4 standards that support near field communication. This is a technology for near field communication and ubiquitous computing of about 10 to 20 meters in the field of wireless networking such as homes and offices. In other words, ZigBee is a concept of a mobile phone or a wireless LAN, and a feature different from the existing technology is a concept of communicating a small amount of information instead of minimizing power consumption.

  In this case, in the present invention, an example in which RF communication (RF 447 MHz communication method) or ZigBee wireless communication is applied as wireless communication has been described. However, the present invention is not limited to this, and the wireless communication is Bluetooth (registered trademark). ), Z-wave, Wi-fi, Wibro, and NFC (Near Field Communication) can be selectively used.

  The terminal 510 is preferably a smartphone that is easy to carry and allows easy installation of the application. Of course, any one of a tablet PC, a mobile phone, a desktop computer, a notebook computer, a tablet notebook computer, and a PDA can be used in addition to the smartphone.

  The smart joinery 1 according to the present invention having such a configuration can monitor the current state of the joinery 1 having various functions in real time via the display window of the terminal 510, as well as various types. Functions can be controlled individually / integrated regardless of location.

  In particular, the lift sliding type smart joinery can be automatically opened and closed using the lifting device 600, and can be switched to manual opening and closing.

  Further, a left / right / stop button B that can automatically open / close the shoji 21 by controlling the automatic opening / closing device 100 and the lifting device 600 may be provided on the surface of the housing 611 of the handle driving unit 610.

  While the present invention has been illustrated and described with reference to specific preferred embodiments, the present invention is not limited to the above-described embodiments, and various changes and modifications may be made without departing from the spirit of the present invention. Of course, it is possible.
