Definitions

  • the present invention relates to tilter for Venetian blind, particularly a tilter mechanism to rotate headrail of the Venetian blind directly.
  • Each Venetian blind is composed of a plurality of vertical or horizontal slats running in parallel, tilting of which can adjust indoor darkness and preserve confidence in personal living. It is being extensively used in offices and homes.
  • the conventional horizontal Venetian blind being used can have its slats tilted and lifted, and comprises mainly a rectangular sectioned and non-rotary headrail, a foot rail, two or more ladders each including an outer ladder and an inner ladder suspending from the headrail to the foot rail to support a plurality of slats with a plurality of connecting tapes located between the outer and inner ladders, and a tilter within the headrail and a transmission device therefor to tilt the slats.
  • the tilter and the transmission device are incorporated with a handle to tilt the slats manually, and are substantially in a form of a drum driven by a worm drive through the handle for rotation, include at least to tilt drums each wound by a ladder to support the ladder, and a transmission shaft located between the tilt drums to rotate the tilt drums simultaneously.
  • the ladders are moved linearly by the tilter, transmission shaft and the tilt drums, the outer and inner ladders are moved in two opposite directions to tilt the slats between them.
  • the conventional tilter for Venetian blind is firmly secured to a headrail, and has a worm drive and a plurality of transmission shafts to rotate the respective ladder drums suspending the slats.
  • Such a tilter has a quite complicated structure, and hence, its production cost is high. Moreover, it is hardly to implement mass production with automatic assembly process, and it indeed has the following defects:
  • the present invention provides a revolutionary design concept for tilter of Venetian blind to overcome the above defects.
  • the tilter according to the present invention can drive the headrail of the blind to rotate directly, and consequently the ladder holders firmed fixed to the headrail to rotate simultaneously without the use of worm drive, gears, long transmission shaft and bearings as needed in the conventional tilter.
  • Tilter mechanism according to the present invention comprises a hollow drum secured to window frame or door frame, an end cover, and a rotary mechanism extended out of the drum and connected to the tubular headrail so that pulling of a tilt cord can drive the rotary mechanism to rotate and consequently rotate the tubular headrail simultaneously so as to tilt the slats suspending from the tubular headrail to any desired angle.
  • the main object of the present invention is to provide a tilter mechanism for Venetian blind with minimum components and simple structure. It is a design that permits mass production with automatic assembly process at low production cost.
  • Another object of the present invention is to provide tilter mechanism for Venetian blind which permits efficient and prompt adjustment of slat tilting, assures easy operation, long service life and minimum failure possibility in comparison with the conventional tilter.
  • Another object of the present invention is to provide a tilter mechanism which can be installed at either end of the headrail to satisfy different user's habit and different indoor installation requirements.
  • Another object of the present invention is to provide a tilter mechanism for Venetian blind to be supplied to the general consumers in the form of a "DIY" kit to permit assembly and replacement of slats by the consumers.
  • the tilter (20) to rotate the headrail (11) directly for tilting of the slats (90) comprises mainly a hollow drum (22) secured to a window frame (93), an end cover (24) to close the hollow drum (22).
  • the hollow drum (22) has a pair of upward extended ribs (26), and the end cover (24) has a cross slot (28).
  • the drums (22) can be easily secured to a side of the window frame (93) with the extended ribs (26) or the cross slot (28) by means of any conventional fasteners.
  • the tilter (20) includes further a rotary member (31).
  • the rotary member (31) is a hollow structure with an extended fixing section (33) and a pulley section (32).
  • the pulley section (32) has two cord ways (34 and 35) formed by three rims.
  • a notch (36) is formed at the middle rim so as to connect the cord ways (34 and 35) are connected together.
  • a tilt cord (37) made of soft material is wound from a cord way (34) to the other cord way (35) through the notch (36).
  • the tilt cord (37) winding on the cord way (34) has an overlapped portion (38).
  • the extended fixing section (33) has four notches (39) arranged annularly in equal distance. As shown in Figs.
  • the extended fixing section (33) can be partly extended from the drum (22) into the tubular headrail (11), and its four notches (39) are engaged with a cross driven element (40) in the tubular headrail (11) when the rotary member (31) is installed into the drums (22). Therefore, when the rotary member (31) is rotated, the tubular headrail (11) is driven to rotate simultaneously.
  • the drum (22) can be secured to either end of the headrail (11), and hence it is designed with a cord outlet (41) in the middle of its bottom side, and two symmetric cord outlets (42 and 43), one at the left side and the other at the right side.
  • both ends of the tilt cord (37) are extended out of the drum (22) through either the cord outlet (42) or another cord outlet (43) so that an end of the tilt cord (37) can be pulled indoors and consequently the rotary member (31) and the tubular headrail (11) can be driven to rotate clockwise or counterclockwise, and then the ladder sets (13) are driven to pull the slats (90) to rotate to the desired angle.
  • the drum (22) has a connecting section (45) composed of a plurality of elastic connecting elements (44) arranged annularly in equal distance near an end of the tubular headrail (11).
  • Each elastic connecting element (44) has a wedged end (46) extending outward.
  • the tilter mechanism according to the present invention has the following advantages:
