Abstract

A beaded-chain control device for window blinds comprises a positioning seat with an assembling cavity defining one side therein for the accommodation of a cord-winding unit equipped with a two-way rotary cylinder thereon wherein the two-way rotary cylinder is driven by a beaded-chain to rotate in clockwise or counterclockwise direction thereby, and the assembling cavity thereof has a passage cut at both lateral sides thereon respectively. The cord-winding unit also has a smaller-diameter winding-shaft protruding at the other end of the two-way rotary cylinder to precisely align with the passages thereof so that an actuating cord can pass through the passage to attach onto the winding-shaft and synchronically actuate each pull cord linked thereto to collect or expand a blind body thereby, permitting smoother operation and reducing the assembly parts to cut the cost of production and achieve economical efficiency thereby.

Description

    BACKGROUND OF THE INVENTION
  • The present invention relates to a beaded-chain control device for window blinds, comprising a positioning seat and a cord-winding unit wherein the position seat has an assembling cavity with a set of passages symmetrically defining both lateral sides thereon and precisely aligned with a winding-shaft protruding at one end of a two-way rotary cylinder of the cord-winding unit so that an actuating cord can pass through the passages to attach onto the winding shaft and synchronically actuate each pull cord of the window blind linked thereto, permitting smoother operation and reducing the assembly parts to achieve economical efficiency thereby.
  • Please refer to FIG. 1. A conventional beaded-chain window blind 10 includes a linking rod 11 synchronically rotated by a beaded-chain operated seat 12. The linking rod 11 has a plurality of cord winders 13 attached thereto, and each cord winder 13 has a pull cord 14 attached thereto. The pull cord 14 is guided to extend through a blind body 15 and fixed to a bottom rail 16 at the other end thereof. Therefore, depending on the revolving direction of the beaded-chain operated seat 12, the cord winders 13 are synchronically rotated along with the linking rod 11 actuated by the beaded-chain operated seat 12 so as to coil up or release the pull cords 14 therewith accordingly.
  • There are some drawbacks to such conventional beaded-chain window blind. First, depending on the number and position of the pull cords 14, the beaded-chain operated seat 12 must have multiple cord winders 13 mounted onto the linking rod 11 to match to the pull cords 14 each attached to one cord winder 13 respectively. Thus, the conventional beaded-chain window blind is not only complicated in its assembling parts, but also inconveniently time-consuming in the assembly thereof, which may boost the cost of production in an uneconomical way. Second, each pull cord 14 is individually wound onto one cord-winder 13. In case one of the pull cords 14 wound onto the cord winders 13 gets entangled in operation, the beaded-chain operated seat 12 will become jammed in an immovable situation and must be repeatedly pulled to return to the normal state, which can cause inconvenience in application thereof.
  • SUMMARY OF THE PRESENT INVENTION
  • It is, therefore, the primary purpose of the present invention to provide a beaded-chain control device for window blinds, comprising a positioning seat and a cord-winding unit wherein the position seat has an assembling cavity with a set of passages symmetrically defining both lateral sides thereon and precisely aligned with a winding-shaft protruding at one end of a two-way rotary cylinder of the cord-winding unit so that an actuating cord can pass through the passages to attach onto the winding-shaft and synchronically actuate each pull cord of the window blind linked thereto, permitting smoother operation without getting entangled or jammed as found in the above-mentioned conventional multiple cord-winders as well as reducing the assembly parts to facilitate easier and speedier assembly and cut the cost of production in an economical way.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Please refer to FIG. 2 showing an exploded perspective view of the present invention. The present invention relates to a beaded-chain control device for window blinds, comprising a positioning seat 20 and a cord-winding unit 30 wherein the positioning seat 20 has an assembling cavity 21 defining the interior therein, a support block 22 with screw holes 221 protruding at one side of the opening edge of the assembly cavity 21, a smaller-diameter pivoting hole 23 cut at the bottom end surface, and a set of rectangular passages 24 symmetrically defining both lateral side surfaces thereon. The cord-winding unit 30 has a stop plate 31 with locking holes 311 disposed thereon extending at one side thereof, and a pivoting shaft 32 protruding at the other side wherein a rotary sleeve 321 with linking teeth 3211 defining thereon, and a positioning spring 322 with abutting legs 3221 protruding thereon are respectively coupled with the pivoting shaft 32 thereof. A two-way rotary cylinder 33 is provided with a restricting block 331 extending at the interior thereon to match to the abutting legs 3221 thereof, and is actuated to rotate either clockwise or counterclockwise depending on the revolving direction of the rotary sleeve 321 thereof. The linking teeth 3211 of the rotary sleeve 321 are driven by a beaded-chain 34 to actuate the rotation of the two-way rotary cylinder 33 thereby. The other end of the two-way rotary cylinder 33 has a smaller-diameter winding-shaft 333 with a set of stop rings 332 extending at both sides thereon wherein the stop rings 332 are shaped larger than the outer diameter of the two-way rotary cylinder 33, and a pivoting axle 334 is provided extending outwards from the stop ring 332 situated at the outer side to fit to the pivoting hole 23 thereby.
  • Please refer to FIG. 3 showing an assembled perspective view of the present invention. In assembly, the two-way rotary cylinder 33 of the cord-winding unit 30 is pivotally adapted into the assembling cavity 21 of the positioning seat 20 till the outer stop ring 332 abuts against the bottom surface of the assembling cavity 21 and locates at one side of the passages 24, permitting the pivoting axle 334 to pivotally join to the pivoting hole 23 thereby. Meanwhile, the locking holes 311 of the stop plate 31 and the screw holes 221 of the support block 22 are reciprocally matched and secured to each other, and the other stop ring 332 situated at the inner side thereof is allowed to locate at the other side of the passages 24, permitting the winding-shaft 333 to precisely align with the passages 24 so that an actuating cord A as shown in FIG. 4 can pass through the passage 24 to attach onto the winding-shaft 333 thereby. And more than two pull cords B as shown in FIG. 5 can be synchronically fixed to the other end of the actuating cord A at one end thereof.
  • In application, the beaded-chain 34 of the cord-winding unit 30 is effortlessly drawn to actuate the two-way rotary cylinder 33 rotating inside the assembling cavity 21 and actuating the synchronic movement of the winding-shaft 333 at the same time as shown in FIG. 6. Then, depending on the revolving direction of the winding-shaft 333, the actuating cord A will be coiled up or released accordingly, and each pull cord B linked to the actuating cord A will be synchronically drawn to collect or expand a blind body thereby in an easy manner without getting entangled and jammed as found in the above-mentioned conventional multiple cord-winders thereof, facilitating smoother operation as well as reducing the assembly parts to cut the cost of production and achieve economical efficiency thereby.
