Definitions

  • the present invention relates to blinds, and more specifically to a blind lifting control mechanism and a method of the same.
  • a variety of blinds including Venetian blinds, roller blinds, pleated blinds, honeycomb shades, Roman blinds, vertical blinds, curtains, and so on are commercially available for use in a window to regulate the light, air, etc.
  • a regular blind generally includes a headrail fastened to a top side of the window, and a blind body (formed of a shade or a set of slats, and a bottom rail) mounted at a bottom side of the headrail. The blind body is driven by an external driving force to change its window shading status.
  • the blind lifting control mechanism of a conventional blind generally includes at least one bobbin, regularly two bobbins rotatably mounted with the headrail of the blind and adapted to roll up or let off lift cords of the blind and to further lift or lower the blind body (in an alternate prior art design, a roller is used instead of the bobbin, and the top side of the blind body is directly fastened to the periphery of the roller), a transmission mechanism mounted inside the headrail of the blind and coupled to the bobbins, and an endless operating cord member suspended from the headrail of the blind at an end for pulling by hand to drive the transmission mechanism to rotate the bobbins (or the roller).
  • each of the two lift cords has a first end fastened to the bottom side of the blind body (for example, the bottom rail of the blind body), and a second end inserted inside the headrail of the blind and through a lift lock in the headrail and then downwardly extended out of the bottom side of the headrail to a distance.
  • the user can pull the lift cords to lift or lower the blind body.
  • the lift lock automatically locks the lift cords.
  • the operating cord member or lift cords are suspended outside the headrail. Because a child can easily reach the suspended part of the lift cords or operating cord member, an accident may occur when a child pulls the lift cords or operates the cord member for fun.
  • the blind lifting control mechanism includes a control rod vertically suspended at a lateral side of the window, two bobbins rotatably mounted with the headrail of the blind for synchronous rotation to roll up or let off lift cords of the blind and to further lift or lower the blind body of the blind, and a transmission mechanism coupled between the control rod and the bobbins.
  • the bobbins are rotated clockwise or counterclockwise to roll up or let off the lift cords of the blind, and to further lift or lower the blind body of the blind.
  • a blind lifting control mechanism 20 in accordance with a first preferred embodiment of the present invention is shown installed in a Venetian blind 10 for lifting control.
  • the Venetian blind 10 includes a headrail 11, which is a hollow bar fixedly fastened to a topside of a window, a blind body 12, which is composed of a number of transversely extended parallel slats 13 and a bottom rail 14 suspended below the slats 13, two lift cords 15 bilaterally and vertically inserted through the slats 13, each lift cord 15 having a bottom end fixedly connected to the bottom rail 14 and a top end inserted into the inside of the headrail 11 (this will be described further), and a tilt control mechanism 16 adapted to regulate the tilting angle of the slats 13.
  • the tilt control mechanism 16 includes a tilt rod 17 vertically suspended from the headrail 11 at a left side thereof and adapted to rotate a tilt rod via a worm gear and tilter mechanism, causing the tilt rod to move two ladder tapes and to further change the tilting angle of the slats 13. Because the tilt control mechanism 16 is a conventional design, no further detailed description is necessary.
  • the blind lifting control mechanism 20 includes two bobbins 25 symmetrically mounted on an axle 27 inside the headrail 11 for synchronous rotation with the axle 27 to roll up or let off the lift cords 15 , a transmission mechanism 30 mounted inside the headrail 11 near a right side thereof, and a control rod 40 .
  • the transmission mechanism 30 includes a worm 31, which includes a worm body 32 vertically suspended inside the headrail 11 and a round rod 33 axially extended from the bottom end of the worm body 32 and partially extended out of the bottom side of the headrail 11 , a worm gear 34 disposed inside the headrail 11 behind the worm 31 and meshed with the worm body 32 , a gear set 35 connected between the worm gear 34 and the axle 27 and adapted to transmit rotary driving force from the worm gear 34 to the axle 27, i.e., the worm gear 34 is the driving force input end of the gear set 35 and the axle 27 is the driving force output end of the gear set 35 .
  • the gear set 35 may be variously embodied.
  • the gear set 35 can be a gear train composed of a series of gears of different diameters meshed with one another, or formed of a number of gears coaxially meshed with one another.
  • the control rod 40 is vertically suspended from the headrail 11 at a right side thereof, having a top end connected to the round rod 33 of the worm 31 by a universal joint 42. Thus, the control rod 40 can be oscillated toward inside of the room relative to the worm 31 (see FIG. 4).
  • the control rod 40 has a bottom end mounted with a manual rotary driving device, for example, a crank handle 44 .
  • the crank handle 44 includes a first arm 45 foldably pivoted to a bottom end of the control rod 40, a second arm 46 foldably pivoted to an end of the first arm 45 remote from the control rod 40 , a grip 47 coupled to the second arm 46 for free rotation relative to the second arm 46 , and a sleeve 48 fitted to the control rod 40 for free rotation and axial movement relative to the control rod 40.
  • the sleeve 48 is longitudinally longer than the first arm 45 .
  • the first arm 45 is set in a horizontal position perpendicular to the control rod 40
  • the second arm 46 is set in a vertical position perpendicular to the first arm 45
  • the sleeve 48 connected to a bottom end of the control rod 40 and being stopped against the first arm 45.
  • the aforesaid worm and worm gear mechanism transmits driving force in one direction only (i.e., the worm 31 rotates the worm gear 34 when receiving a rotary driving force, however the worm 31 stops a rotary driving force coming from the worm gear 34 ), therefore the user can control the control rod 40 to rotate the bobbins 25, and a self-locking mechanism of the aforesaid worm and worm gear mechanism automatically locks the bobbins 25 when the user adjusted the blind 12 to the desired elevation, i.e., the blind 12 is positively positioned at the adjusted elevation.
  • the invention does not use any lift cord or like means to achieve blind lifting control, it eliminates the possibility of a person (more particularly a child) hanged on the lift cord accidentally. Therefore, the blind is safe for use and fits blind safety codes in advanced countries.
  • the aforesaid blind lifting control mechanism can also be used in another equivalent blind, for example, a pleated blind, honeycomb shade, or roman blind.
  • a roller is used instead of the two bobbins and, the top side of the blind body is fastened to the periphery of the roller.
  • a crank handle 44 is mounted at the bottom side of the control rod 40 of the lifting control mechanism 20 for enabling the user to rotate the control rod 40 with less effort.
  • this crank handle 44 is not requisite.
  • An accelerating mechanism may be installed in the transmission mechanism 30 so that the user can rotate the straight control rod 40 directly without much effort.
  • FIG. 7 shows a blind lifting control mechanism according to a second preferred embodiment of the present invention.
  • the blind lifting control mechanism 50 includes two bobbins 52 (similar to the bobbins of the aforesaid first embodiment), a transmission mechanism 54 (similar to the transmission mechanism of the aforesaid first embodiment), a control rod 56, and a detachable crank handle 60.
  • the control rod 56 has a coupling device at a bottom end thereof, for example, a hexagonal coupling hole 57.
  • the crank handle 60 includes a L-shaped crank arm 61, a driving rod 62 axially forwardly extended from an end of the L-shaped crank arm 61 and terminating in a coupling device, for example, a hexagonal coupling tip 64 that fits the hexagonal coupling hole 57 , a sleeve 63 sleeved onto the driving rod 62 for free rotation, and a grip 65 perpendicularly extended from the other end of the L-shaped crank arm 61 in direction reversed to the driving rod 62.
  • a coupling device for example, a hexagonal coupling tip 64 that fits the hexagonal coupling hole 57 , a sleeve 63 sleeved onto the driving rod 62 for free rotation, and a grip 65 perpendicularly extended from the other end of the L-shaped crank arm 61 in direction reversed to the driving rod 62.
  • the crank handle 60 is attached to the bottom end of the control rod 56 for enabling the user to rotate the control rod 56 with less effort.
  • FIG. 8 shows a blind lifting control mechanism according to a third preferred embodiment of the present invention.
  • an electric rotary driving device 73 is used for rotating the control rod 71 .
  • the control rod 71 has a coupling portion, for example, a hexagonal coupling hole 72 at the bottom end thereof.
  • the electric rotary driving device 73 includes a housing 74 , a battery power supply and motor assembly (not shown) mounted inside the housing 74 , a driving shaft 76 extended from the output shaft of the reversible motor of the battery power supply and motor assembly out of the housing 74 and terminating in a coupling device, for example, a hexagonal coupling tip 77 that fits the hexagonal coupling hole 72 of the control rod 71 , and a switch 75 adapted to control on/off and forward/backward rotation of the reversible motor of the battery power supply and motor assembly.
  • a coupling device for example, a hexagonal coupling tip 77 that fits the hexagonal coupling hole 72 of the control rod 71
  • a switch 75 adapted to control on/off and forward/backward rotation of the reversible motor of the battery power supply and motor assembly.
