20100264244 | FLEXIBLE CONDUIT STORAGE DEVICE - The present invention relates to a device for storing a flexible conduit, such as an electrical cord of a set of personal head phones or similar. The device has a body and a drum rotationally coupled to the body. The drum is biased to rotate in a first direction. A latch movable between a latched position and an unlatched position prevents rotation of the drum in the first direction when the latch is in the latched position. The body has an opening for positioning a portion of flexible conduit. At least one coupling disposed on the drum extends into the opening for catching a portion of a flexible conduit positioned within the opening. When the latch is in the unlatched position the drum rotates in the first direction to cycle the coupling through the opening. A coupling catches a flexible conduit positioned within the opening to wind the flexible conduit onto the drum. | 10-21-2010 |

20120032019 | ACTIVATING DEVICE FOR CORDLESS BLIND - An activating device for a cordless blind includes a driving reel, a first transmission reel rotatable by the actuation of a cord connected between the driving reel and the transmission reel, and a second transmission reel rotatable by an actuation of a constant torque spring connected between the first and second transmission reels. As a result, when the cordless blind is lowered, the driving reel can be driven to rotate by two strings, which in turn leads a rotation of the first transmission reel by the cord and a rotation of the second transmission reel by the constant torque spring. When the cordless blind is lifted, the first and second transmission reels can be driven to rotate reversely and synchronously by the rebound force of the constant torque spring, causing the driving reel to rotate reversely through the cord. | 02-09-2012 |

When the first end part of the cord is no longer pulled, the two protruding blocks are respectively contacted with two notches of the inner surface of the cord positioning element. Consequently, the rotating disc and the cord positioning element are not rotated. When the push button is pressed down, the rotating disc and the cord positioning element are rotated in a second direction in response to a restoring force of the spiral spring. Consequently, the cord is retracted back. | 11-06-2014 |

20110062268 | RETRACTABLE CABLE DEVICE HAVING PROTECTING FUNCTION - A retractable cable device having protecting function mainly comprises a housing, a spiral spring, a spool disk, an arresting system, and a communication cable. The spool disk pivoted on a shaft within the housing is wound by the communication cable. The spiral spring provides the spool disk with a reeling force to reel in the communication cable. The rotation of the spool disk flexibly controlled by the arresting system decides the protruding length of the communication cable. A swaying member installed on the spool disk is utilized to replace the conventional immovable clip for fixing the communication cable. Whereby, when the entire communication cable is drawn out, the communication cable at a second end of the swaying member presents a larger bent angle. Therefore, the communication cable is subjected to bending with less sharp degree, thence protecting the communication cable, especially for the core, by preventing it from damage. | 03-17-2011 |
