JP6692412B2 - Lifting device with automatic / manual switching structure and smart fitting including the same - Google Patents

Description

  The present invention relates to a smart fitting that can automatically open and close a shoji screen, and more specifically, it can automatically open and close a lift sliding type smart fitting, and can also be opened and closed by switching to a manual operation. The present invention relates to a lifting device having an automatic / manual switching structure capable of opening and closing a shoji screen with a simple button operation, and a smart fitting including the same.

  Generally, the fitting serves as a wall that separates the room and the room from outside, and at the same time, allows the room to ventilate by letting in sunlight and fresh outside air.

  Such fittings can be classified into various types according to the material or the opening method. Depending on the opening method, the tilt and turn (Tilt & Turn) method that can open and close the shoji screen inwardly and the lift function There is a lift sliding method in which a shoji screen is moved up and down on a rail by using the above hardware.

  The lift sliding method is a method in which a fixed window is placed and one or both sides of the fixed window are opened. Patent application 1 has been previously filed for such a lift sliding fitting.

  More specifically, the lift sliding fitting has a basic structure including a fixed window installed in a window frame and a shoji that opens and closes while moving left and right along rails formed on the upper and lower portions of the window frame. Besides, hardware for moving the lock and the shoji up and down or in the horizontal direction to ensure airtightness is installed.

  In the Lift sliding fitting having such a structure, 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 slides horizontally and opens quietly and smoothly. When the shoji screen is closed, the shoji screen and the rail come into close contact with each other, so that airtightness, watertightness, and heat insulation can be secured.

  Such a lift sliding fitting may have a structure in which an electric actuator is operated to automatically lift the fitting. However, such a lift sliding fitting has a problem that the fitting cannot be lifted when the electric actuator fails.

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

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

  However, most of the automatic opening / closing devices for such shoji screens, ventilation devices, etc. are systems in which the user has to directly operate in a short distance indoors with a remote controller or the like.

  Therefore, in most cases, when a user goes out, it is inconvenient to operate the ventilation device and open / close the shoji, or to close the shoji that has been opened during a sudden rainy day. ..

  FIG. 1 is a perspective view of a smart fitting according to the present invention, and FIG. 2 is an interior side elevational view of the smart fitting according to the present invention.

  Referring to FIGS. 1 and 2, a smart fitting 1 according to a preferred embodiment of the present invention includes a window frame 10, a lift sliding shoji 21 that is automatically lifted through a lifting device 600, and a lifted shoji. And an automatic opening / closing device 100 for automatically opening and closing 21.

  The structure of the present invention will be described in detail below.

  The window frame 10 constitutes a main outer frame of a lift sliding fitting, and the upper and lower contact surfaces of the window frame 10 have rails along the longitudinal direction so that at least a pair of shoji 20 can be slidably opened and closed. (Not shown).

  Referring to FIGS. 2 and 3, the lift sliding shoji 21 is automatically lifted on a rail by a lifting device 600 at a certain height during an opening / closing operation and then horizontally opened / closed. Can be provided with a gasket (or mohair or the like) that is in close contact with the inner surface of the window frame 10 to maintain airtightness during the closing operation.

  Specifically, the lifting device 600 includes a handle driving unit 610, and an operating rod installed so that the power of the handle driving unit 610 is transmitted through a gear module 630 (as an example, a rack and a pinion gear) so as to be vertically movable. 631, a connecting link 633 connected to the actuating rod 631, installed at a lower corner of the shoji 21 to convert vertical motion into horizontal motion, and connected to the connecting link 633 and at the bottom of the shoji 21. The sliding shaft 21 is slidably installed along the longitudinal direction, and when the handle driving unit 610 is operated, the guide shaft 641 provided inside thereof pushes up or pushes down the slanted guide elongated hole 643a of the elevating block 643. A slider 640 for moving up and down on a rail, and a lower part of the slider 640 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 in any one shoji 21 of at least a pair of shoji 20 slidably installed in the window frame 10, and a housing 611 inside the housing 611. A drive motor 613 installed, a shaft 617 that is rotatably coupled to a rotation shaft of the drive motor 613 via a gear train 615, and the gear train 615 and the shaft 617 are meshed with each other to be connected to each other. A clutch gear 619 which is slidably and axially coupled to the shaft 617 along the axial direction so that power can be selectively coupled and elastically supported on one side by an elastic member 618; A cover 621 coupled to 611.

  In this case, the cover 621 may be slidably connected to the housing 611, or may be pivotally connected to one side via a hinge shaft so as to be rotatable and openable.

  Further, the handle H is embedded in the 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 and used.

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

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

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

  In the handle driving unit 610 having such a structure, the clutch gear 619 connects the gear train 615 and the shaft 617 while pressingly moving the clutch gear 619 in the axial direction of the other side when the cover 621 is coupled.

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

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

  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 on any one of the sliding doors 21 which is opened and closed among at least one pair of sliding doors 20, and serves to automatically open and close the sliding door 21. The automatic opening / closing device 100 may be installed in an upper part or a lower part, or both an upper part and a lower part in a summing frame 21a in which a pair of shoji 20 are fitted together. In the present invention, an example of a case where the automatic opening / closing device 100 is installed in each of the upper and lower parts of the assembling frame 21a will be illustrated and described.

  The automatic opening / closing device 100 includes a driving motor 110 installed in the summing frame 21a of the sliding door 21 and one of the stationary sliding doors 23 adjacent to the driving motor 110, which is rotated by transmitting power of the driving motor 110. And a drive roller 120 that is installed such that the outer peripheral surface abuts on the surface 23a of the above and slides and opens and closes the shoji 21.

  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 the shaft 111 that connects the drive motor 110 and the drive roller 120, and selectively shuts off the power transmitted to the drive roller 120. You can switch to manual and open.

A first gear 113 that is integrally coupled to the rotation shaft of the drive motor 110 is provided, and the first gear 113 meshes with the second gear 115 so that the shaft 111 is not engaged. The drive roller 120 is driven by a rotating method. At this time, the second gear 115 is in a state of being idlely coupled to the shaft 111. The electromagnetic clutch 130 is connected in parallel with the second gear 115 on the same axis of the shaft 111. The electromagnetic clutch 130 rotates integrally with the shaft 111, and has an electromagnet (not shown) inside.

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

  On the contrary, when the current flowing through the electromagnet is cut off, the electromagnetic clutch 130 and the second gear 115 are separated from each other, and the power of the drive motor 110 transmitted to the drive roller 120 is cut off. Therefore, it is possible to smoothly and manually open and close the shoji 21 when a power failure or a failure of the automatic opening / closing device 100 occurs.

  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 the noise generated.

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

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

  Further, one surface 23a of the shoji 23 which contacts the outer peripheral surface of the driving roller 120 is provided with a concavo-convex pad 123 which meshes with the concavo-convex groove 121 so as to prevent a slip phenomenon when the driving roller 120 is first driven. Good. The concavo-convex pad 123 may be formed over the entire area along the opening / closing direction of the one surface 23a of the shoji 23, but may be applied only to a predetermined section in which the stopped drive roller 120 is first driven. Of course good things.

  The automatic opening / closing apparatus 100 may further include a safety sensor 140 so that the operation of the drive motor 110 can be immediately stopped when a person or an object passing through the sliding door 21 is detected without confirming the closing operation of the shoji screen 21. You can The safety sensor 140 may be installed on the summing frame 23a or the tip thereof when the shoji 21 is closed. In the present invention, an example of the case of being installed on the summing frame 23a will be described.

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

  The natural ventilation part 200 is installed in the shoji 20 to ventilate the air in the room, and such a natural ventilation part 200 is preferably installed in the fixed shoji 23 which is not opened and closed among at least a pair of shoji 20.

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

  In this case, as for the ventilator for joinery used in the natural ventilation part 200, Korean Patent No. 10-1274838, registered patent No. 10-1259671, registered patent No. 10- filed by the present applicant. 1260564, registered patent No. 10-1301811, registered patent No. 10-1293852, registered patent No. 10-1307645, registered patent No. 10-1433437, registered patent No. 10-1293846, registered patent No. 10-1292365. , Registered Patent No. 10-1330447, Registered Patent No. 10-1252906, Registered Patent No. 10-1272994, Registered Patent No. 10-1335847, 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, and a ventilation device generally used for fittings may be applied and used. A detailed explanation of the operating principle of such a ventilator for fittings will be omitted.

  The light control unit 300 is installed on a part or the whole of the glass provided on the shoji screen 20, and plays a role of switching the light transmittance of the glass to a transparent or opaque state. Usually, the "magic glass" is used. Also called.

  The magic glass used in the light control unit 300 has a bonded glass structure in which an ITO film and a liquid crystal are put together between two pieces of glass and pressure-bonded. By applying a voltage to the magic glass, the light control unit can instantaneously switch from an opaque state to a transparent state due to a change in the arrangement of molecules between the ITO films. You can freely produce changes.

  The liquid crystals, which are represented as rod-shaped molecules when no voltage is applied, are aligned along the inner wall of the capsule. Light entering 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 cannot travel straight and is scattered and appears opaque.

  When a voltage is applied, the liquid crystal molecules are aligned in the direction perpendicular to the electrodes due to the property that they tend to be parallel to the direction in which the voltage is applied. In this arrangement, if the liquid crystal has a refractive index that matches the refractive index of the polymer, the liquid crystal becomes the same as that without the capsule interface, and the light goes straight without being scattered. Therefore, the magic glass looks transparent.

  The light control unit 300 having the above structure may be applied to the entire glass of the shoji screen 20, or may be divided into a plurality of parts in the up / down and left / right directions of the shoji screen 20 to selectively be transparent / opaque. Various controls are possible.

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

  In this case, the sensor 410 includes at least one pair of magnet type sensors that are attached to the sliding door 21 and the window frame 10 so as to correspond to each other and detect whether the sliding door 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 10 corresponding thereto. Of course, the present invention is not limited to this, and various modifications can be applied as long as the position can easily detect whether or not the shoji 21 is forcibly opened and closed.

  The control unit 500 controls the respective components 100, 200, 300, 400, 600 individually / integratedly by using the wireless communication terminal 510 of the user regardless of time and place, and performs wireless communication. The states of the components are displayed in real time on the display window of the terminal 510.

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

  In this case, it is preferable that the wireless communication uses an RF communication method. Of course, the present invention is not limited to this, and Zigbee wireless communication that supports near field communication can be applied and used. For reference, ZigBee wireless communication refers to one of the IEEE 802.15.4 standards that supports near field communication. It is a technology for short-distance communication of about 10 to 20 m and ubiquitous computing in the field of wireless networking such as homes and offices. That is, 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, the present invention has been described by taking an example in which RF communication (RF 447 MHz communication system) or ZigBee wireless communication is applied as wireless communication, but 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 also be selectively used.

  The terminal 510 is preferably a smartphone that is easy to carry and easy to install the application. In addition to the smartphone, 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.

  The smart fitting 1 according to the present invention having such a configuration can of course monitor the current state of the fitting 1 having various functions in real time through the display window of the terminal 510 in various ways. Functions can be controlled independently / integrated regardless of location.

  In particular, the lifting sliding device 600 can be used to automatically open and close the lift sliding type smart fitting, and it is also possible to manually open and close it.
