Venetian window with movable elevating blinds

Abstract
A Venetian window with movable elevating blinds includes a window frame, a vertical pivotal plate separately installed on internal left and right sides of the window frame, a vertical groove disposed at the pivotal plate for engaging a pivotal portion of a plurality of blinds and moving the blinds vertically up and down, a pivotal hole separately disposed at the top of two side frames and pivotally coupled to the pivotal portion on both sides of the blinds, two surrounding strips for fixing and maintaining each blind in a balanced position and driving each blind to rotate synchronously, a cap disposed at an end of the two pulling strings for passing each blind and fixing it at the bottom of the blind, and a handling knob disposed at another end of a control wheel module, such that the pulling string can be operated to pull the blinds up or down.

BLINDS AND COMPONENTS THEREOF

Abstract
The invention relates to blinds, components of blinds and assembly of blinds, and particularly to the tilt mechanism of a Venetian blind. The tilt mechanism includes a slider element to which the cords of the cord ladder are attached. The slider element has a base portion fixedly mounted in an aperture of the head rail, and a sliding portion. The ladder cords are routed through holes in the base portion, through a void between the sliding portion and the base portion and out of the ends of the slider element. The ends of the ladder cords are secured proximate respective ends of the sliding portion. The void is divided into separate chambers and the holes of the base portion communicate each with a respective chamber. A further hole and chamber may be provided to accommodate a lift cord. Tangling of the cords is eliminated, and the compact arrangement allows a slim and attractive head rail to be used.

Ladder tape and bottom rail positioning structure for venetian blinds

Abstract
A ladder tape and bottom rail positioning structure for Venetian blinds comprises head and bottom rails, lift cords, wide-type ladder tapes, pulley seats, and slats wherein the ladder tape has both ends extending to wind around the underside of the bottom rail with an overlapping portion formed and secured thereto via multiple stapling elements. A flexible plastic positioning cover having insert ends protruding thereon is mounted to the underside of the bottom rail corresponding to the overlapping portion thereof, and the inert ends are precisely hooked adjacent to both lateral sides of the ladder tape to form a limiting groove there-between, permitting stable position of the ladder tape clamped between the positioning cover and the bottom rail and restrained by the limiting grooves thereof. Thus, the overlapping portion of the ladder tape and the stapling elements can be accurately concealed inside the positioning cover for decorative purpose thereof.
