Definitions
- the present invention relates generally to a window blind and, more specifically, to a window blind having multiple driving modes.
- window blinds include two types, one with the cord members exposed to the outside, the other with the cord members arranged in a hidden status.
- a window blind with exposed cord members is not safe in use because the exposed cord members are accessible to children, and an accident may happen when a child playing with the cord members for fun. Therefore, window blinds with exposed cord members are not popularly acceptable at the present time.
- window blinds with hidden cord members have been disclosed, and have appeared on the market. These window blinds with hidden cord members include manually operated type window blinds and motor-driven type window blinds.
- a manually operated type window blind uses the tension force of a spring member or positioning cord member to support the bottom rail in position.

Abstract
Description
- The present invention relates generally to a window blind and, more specifically, to a window blind having multiple driving modes.
- Conventional window blinds include two types, one with the cord members exposed to the outside, the other with the cord members arranged in a hidden status. A window blind with exposed cord members is not safe in use because the exposed cord members are accessible to children, and an accident may happen when a child playing with the cord members for fun. Therefore, window blinds with exposed cord members are not popularly acceptable at the present time.
- Various window blinds with hidden cord members have been disclosed, and have appeared on the market. These window blinds with hidden cord members include manually operated type window blinds and motor-driven type window blinds. A manually operated type window blind uses the tension force of a spring member or positioning cord member to support the bottom rail in position. The use of spring means or positioning cord member cannot eliminate the problem of elastic fatigue. When the problem of elastic fatigue occurred, the spring means or positioning cord member can no longer support the bottom rail accurately in position. Netherlands Patent No. 9000285 and France Patent No. 2692002 teach the use of an elongated handle to drive a linking mechanism at the outside of the headrail and to further change the shading status of the blind body. However, because the linking mechanism is located on the outside of the headrail at an overhead location, the handle must have a certain length. It is not easy to connect the handle to the linking mechanism (because the end of the handle held by the user is the fulcrum, the positioning of the other end of the handle becomes unstable when the fulcrum vibrated with the user's hand. Further, when driving the handle to turn the linking mechanism after connection of the handle to the linking mechanism, the handle may slip from the linking mechanism due to uneven application of force to the handle. In general, the control of the prior art window blinds is not convenient.
- It is the main object of the present invention to provide a window blind, which enables the user to control the shading status of the blind body conveniently.
- It is another object of the present invention to provide a window blind, which has no cord member or string means exposed to the outside, preventing hanging of the exposed cord member or string means on a child accidentally.
- To achieve these objects of the present invention, the window blind comprises a headrail; a blind body suspended below the headrail and movable by an external force to change window shading status; a linking mechanism mounted inside the headrail and having a power input device fastened pivotally with the headrail and rotatable by an external force, and an actuator movable with the power input device and connectable to the blind body for moving the blind body to further change the window shading status upon rotation of the power input device; and a driving control mechanism. The driving control mechanism includes a suspension rod and a controller. The suspension rod has a top end coupled to the power input device and a bottom end downwardly spaced below the headrail at a distance and provided with a connecting portion. The controller has a connecting portion connectable to the connecting portion of the suspension rod for enabling the suspension rod to be driven by the controller to rotate the power input device.

-
- Referring to FIG. 1, a window blind 100 in accordance with the first preferred embodiment of the present invention is shown comprised of a
headrail 10, ablind body 20, a linkingmechanism 30, and adriving control mechanism 40. - The
headrail 10 is transversely (horizontally) affixed to the top side of the window (not shown). Theblind body 20 can be a slat set for Venetian blind or a curtain for a window covering. According to this embodiment, theblind body 20 is a piece of curtain suspended below theheadrail 10 at the one side of the window inside the house, and controlled by an external drive force to change its window shading status. - The linking
mechanism 30 is a mechanical mechanism without power source installed in theheadrail 10, comprising apower input device 31 and an actuator 32.Thepower input device 31 is rotatable by an external biasing force. Theactuator 32 is directly (or indirectly) coupled to theblind body 20, and rotatable subject to the rotation of thepower input device 31. - Referring to FIGS. 2 and 3 and FIG. 1 again, the
power input device 31 is comprised of aworm 311 fastened pivotally with theheadrail 10 in vertical. Theactuator 32 is comprised of aworm gear 321 fastened pivotally with theheadrail 10 and meshed with theworm 311, and anaxle 322 axially suspended in theheadrail 10 and fixedly connected to the axial center of theworm gear 321. Theblind body 20 has its top side edge fixedly connected in parallel to the periphery of theaxle 322. When rotating theactuator 32, theblind body 20 is rolled up or let off, changing the window shading status. Alternatively meshed bevel gears may be used to substitute for the worm and worm gear. - The
driving control mechanism 40 is comprised of asuspension rod 41 and acontroller 42. Thesuspension rod 41 is a rod member having a predetermined length. The top end of thesuspension rod 41 is coupled to the bottom end of thepower input device 31 by auniversal joint 48. The bottom end of thesuspension rod 41 extends vertically downwardly to an elevation where the user's hand is conveniently accessible. Further, the bottom end of thesuspension rod 41 forms into a hexagonalmale coupling portion 411 and then a connectingportion 43. The outer diameter of thehexagonal coupling portion 411 is greater than the connectingportion 43. Aprotective sleeve 49 is sleeved onto thesuspension rod 41 around the bottom end, having a hexagonalfemale coupling portion 491 coupled the hexagonalmale coupling portion 411 for enabling theprotective sleeve 49 to be moved axially along thesuspension rod 41 between a first position where the connectingportion 43 is disposed outside the protective sleeve 49 (see FIG. 4) and a second position where the connectingportion 43 is received inside the protective sleeve 49 (see FIG. 5). Theprotective sleeve 49 further comprises stop means, for example, aninside stop flange 492 radially inwardly projecting from the top end of the periphery of the hexagonalfemale coupling portion 491. When theprotective sleeve 49 moved to the second position, theinside stop flange 492 is stopped against a part of thesuspension rod 41 at the top side of the hexagonalmale coupling portion 411 to stop theprotective sleeve 49 from falling out of the suspension rod 41 (see FIG. 5). - The
controller 42 is a three-segment crank handle comprising afirst driving rod 44, asecond driving rod 45, and athird driving rod 46. Thedriving rods controller 42 can be alternatively set between an operative position where thesecond driving rod 45 kept in horizontal, keeping thefirst driving rod 44 and thethird driving rod 46 vertically arranged in parallel, and a received position where thefirst driving rod 44, thesecond driving rod 45, and thethird driving rod 45 are vertically aligned in a line. Further, thefirst driving rod 44 has a connectingportion 47 formed at its free end detachably coupled to the connectingportion 43 of thesuspension rod 41. According to this embodiment, theconnection portion 43 is formed of a hexagonal coupling rod, and the connectingportion 47 is a hexagonal coupling hole adapted to receive the hexagonal coupling rod of the connectingportion 43. After the connectingportion 47 of thecontroller 42 has been connected to the connectingportion 43 of thesuspension rod 41 and thecontroller 42 has been set in the operative position, the user can then drive thethird driving rod 46 to rotate thefirst driving rod 44 and thesuspension rod 41 efficiently with less effort, thereby causing thepower input device 31 of the linkingmechanism 30 to move theblind body 20 to the desired shading status. - Therefore, when wishing to change the shading status of the
blind body 20, the user can attach to thecontroller 42 to thesuspension rod 41 and then drive thecontroller 42 to rotate thesuspension rod 41 and to further drive thedriving mechanism 40 to rotate thepower input device 31 of the linkingmechanism 30, causing theactuator 32 to move (to roll up/let off, to lift/lower, or to extend/receive) the blind body to the desired shading status. Because the bottom end of thesuspension rod 41 is spaced below the headrail of the window blind at a distance where the user's hand is conveniently accessible, the user can conveniently attach thecontroller 42 to the suspension rod for operation. - Further, for a fine adjustment (lifting, lowering, or tilting the blind body gently), the user can directly rotate the suspension rod with the hand without the use of the controller.
- FIGS. 6 and 7 show a window blind 200 constructed according to the second preferred embodiment of the present invention. According to this embodiment, the window blind 200 is comprised of a
headrail 50, ablind body 60, a linkingmechanism 70, and adriving control mechanism 80. - The
driving control mechanism 80 is comprised of asuspension rod 81 and acontroller 82. Thesuspension rod 81 is a rod member having a predetermined length. The top end of thesuspension rod 81 is coupled to the bottom end of thepower input device 71 of the linkingmechanism 70. The bottom end of thesuspension rod 81 extends vertically downwardly to an elevation where the user's hand is conveniently accessible and terminating in a connectingportion 83. According to this embodiment, the connectingportion 83 is a hexagonal coupling hole having an opening facing downwardly. Thecontroller 82 is an electric controller comprising ahandheld box 84, atransmission rod 87 extended out of thehandheld box 84 and terminating in acoupling portion 85, for example, a hexagonal coupling tip detachably fitted into the hexagonal coupling hole of the connectingportion 83 of thesuspension rod 81, a reversible motor (not shown) mounted inside thehandheld box 84 and adapted to rotate thetransmission rod 87, a battery pack (not shown) mounted inside thehandheld box 84 and adapted to provide the necessary working voltage to the reversible motor, andcontrol switches 86 adapted to control the operation of the reversible motor (for example, to control forward/backward rotation of the reversible motor at a high speed and to further extend/receive the blind body, or to control forward/backward rotation of the reversible motor at a low speed and to further adjust the tilting angle of the slats of the blind body). - When wishing to change the shading status of the
blind body 60, thecoupling portion 85 of thecontroller 82 is attached to the connectingportion 83 of thesuspension rod 81, and then the control switches 86 are operated to turn thetransmission rod 87 and then thesuspension rod 81 and thepower input device 71, thereby causing theblind body 60 to be moved to change the shading status. - As indicated above, the window blind with multiple driving modes according to the present invention has the following features and advantages.
- 1. A window blind made according to the present invention has no cord member or string means exposed to the outside, preventing hanging of exposed cord member or string means on a child accidentally. Therefore, a window blind made according to the present invention is in conformity with the market window blind developing trend and the related window covering safety codes.
- 2. Because the controller is set in the position conveniently accessible to the user's hand, the user can conveniently drive the window blind through a manual driving mode (through the three-segment crank handle type controller) or a motor driving mode (through the electric controller).
- 3. Because the invention does not use the tension force of spring means or cord means to support the blind body at the desired elevation, the invention eliminates the blind body unstable positioning problem due to elastic fatigue of spring means or loosening of cord means, and can control (or maintain) the status of the blind body steadily.
- 4. The user can directly rotate the suspension rod with the hand, or use a manually operated crank handle or an electric controller to drive the suspension rod. Therefore, the window blind provides multiple driving modes for selection.
