20120266413 | CURTAIN CONTROL DEVICE - A curtain control device has a stroke setting device and a damper respectively assembled at both ends of a curtain spindle rod. A torsion element is further assembled on the curtain spindle rod. A curtain spindle sleeve is invaginated on the outside of the curtain spindle rod, the stroke setting device and the damper. The curtain spindle sleeve is assembled with the combination of the curtain spindle rod and the damper, and then a curtain fabric is assembled on the outside of the curtain spindle sleeve. In this manner, the opening range of the curtain fabric roll is controlled by the stoke setting device, and the roll-up speed of each part of the curtain fabric is slowed down by the damper so as to reduce effectively the noise produced by the quick actuation of each part and the defective rate. | 10-25-2012 |
20130000082 | SAFETY RETAINER FOR CURTAIN CORD - A safety retainer for curtain cords is revealed. The safety retainer is used to hold a cord used to open and close curtains in place. The safety retainer includes an inner base and an outer base that are disposed with fixing holes. The inner base and the outer base are fixed on a wall while the cord for control of curtains is passed through the fixing holes. Thereby the cord is held in place by the safety retainer to prevent children from pulling out and being strangled by the cord. | 01-03-2013 |
20130340952 | SLAT ROTATION, SLAT WINDING AND UNWINDING CONTROL DEVICE OF WINDOW BLIND - In the present invention, flexible snap fit portions are provided on the base to engage directly into the upper beam so that the mounting of the base into the interior of the upper beam is easy. A cord spool is designed to be capable of continuing its rotation in a fitting member so that there is no limitation on the winding direction of the pull cord. Moreover, the fixing of either a connecting strap or a connecting string for connecting each slat of the window blind on a housing member is very easy. Therefore, easiness and handiness in operation can be improved in the overall implementation of the present invention. | 12-26-2013 |
20140041815 | ROLLER BLINDS CONTROLLER STRUCTURE - An improvement of roller blinds controller is provided, it mainly comprises a cylindrical rod passing through a side cover and fixing therewith; a bead chain sprocket and a number of torsion springs fitted on the cylindrical rod, and an outer sleeve cover fitted on the outside, wherein: the cylindrical rod has a ridge portion protruded from the circumferential surface thereof, while the side cover has a has a central aperture with a annular edge portion, the cylindrical rod can be fixed with the side cover by the snap-fitting of the annular edge portion between the flange portion and the ridge portion. | 02-13-2014 |
20140084100 | TORSION SPRING FOR CONTROL UNIT OF CURTAINS - A control unit for curtains includes a frame connected with a shaft and a torsion spring is mounted to the shaft. Two extension sections extend from two ends of the torsion spring at an angle. At least one of the two extension sections of the torsion spring has a contact section extending therefrom at an angle. The contact section contacts the end of the protrusion of the socket in a form of face-to-face. By the contact section of the torsion spring, the extension section and the contact section of the torsion spring does not shift to the underside of the protrusion. | 03-27-2014 |
20140284005 | PLEATED CURTAIN GLIDER UNIT - A glider unit for pleated curtain comprises a sliding carriage and a fastener. The sliding carriage has a female snap-fit portion provided at its bottom for engaging with the fastener. The fastener has a combining section for fixing with a curtain fabric. The outer edge of the female snap-fit portion is formed as an arc segment, whereby the curtain fabric can be compliant with the arc segment so as to form regularly pleated pattern and smooth fabric surface during the closing of the curtain. Two pulleys pivotally coupled by a shaft are respectively mounted at both sides of each sliding carriage for moving on a curtain track. A plurality of balls are disposed between each pulley and the shaft so as to facilitate the rolling of each pulley without much application of force, so that opening and closing of the curtain can be accomplished in less laborious effort required. | 09-25-2014 |
20140338847 | CURTAIN CONTROL ASSEMBLY - A curtain control assembly includes a shaft in which a torque rod and a control unit are received. The curtain is wrapped around the shaft. The control unit has a frame from which a tubular portion extends. The tubular portion has a polygonal protrusion. An end support is located in the frame and has a hook which is hooked to the control unit. A bead-chain disk is mounted to the tubular portion. A mount is mounted to a sleeve of the bead-chain disk. A connection member is fixed to the torque rod and a polygonal recess is defined in the connection member. The protrusion is engaged with the recess. A screw extends through the connection member, the tubular portion and is fixed to the end support. The feed-back of torque from the torque rod is shared by the polygonal recess and protrusion to protect the hook from being broken. | 11-20-2014 |
20150129141 | INSTALLATION UNIT OF WINDOW CURTAIN ASSEMBLY - An installation unit for installation to a rail of a window curtain assembly includes an elongate rack and multiple slots are defined through the rack. Multiple sliding members are connected to the rack. The sliding members are installed to the rail of the window curtain assembly. By removing the rack from the sliding members, the sliding members are remained in the rail of the window curtain assembly. The installation of the sliding members to the rail is easy and quick. | 05-14-2015 |
