Abstract

A combined tilt and lift control, for use with a window covering having slats suspended by ladder tapes connected to the slats, and slat lift elements for raising and lowering the slats and a tilt and lift control rod for operating the combined tilt and lift control, the tilt and lift control having a drum for securing and operating the ladder tapes and defining a hollow interior, a lift element opening in the drum bearings, a lift reel rotatably mounted in the drum, a two way rotation control connecting between the lift reel and the drum so that operation of the tilt and lift control rod between predetermined limits will be transmitted to the drum to cause movement of the ladder tapes and tilting of the slats, and so that movement of the tilt and lift control rod beyond such limits, will release the lift reel from the drum and cause operation of the reel independently of the drum.

Dependent claims

A combined tilt and lift control, for use with a window covering having a head rail, slats suspended from said head rail by ladder tapes extending from said head rail and connected to said slats, and slat lift elements extending from said head rail for raising and lowering said slats, and a tilt and lift control rod in said head rail for operating said combined tilt and lift control and means for operating said tilt and lift control rod, said tilt and lift control comprising;

drum means for securing and operating said ladder tapes and defining a hollow interior;
sleeve means within said drum means and formed integrally therewith;
a lift element opening defined by said drum means;
a lift control reel means rotatably mounted within said drum means;
body means formed as part of said control reel means and rotatably received in said sleeve means;
bearing means defined by said body means for rotatably supporting said body means, said reel means and said drum means
two way rotation control means located within the hollow interior of said drum means and connecting between said lift element reel means and said drum means, whereby operation of said tilt and lift control rod between predetermined limits will be transmitted to said drum means to cause movement of said ladder tapes and tilting of said slats, and wherein movement of said tilt and lift control rod beyond said limits, will release said lift control reel means from said drum means and cause operation of said reel means independently of said drum means.

4 more elements

A window covering having a head rail, slats suspended from said head rail by ladder tapes and ladder tapes extending from said head rail and connected to said slats and slat lift elements extending from said head rail for raising and lowering said slats and comprising;

a tilt and lift control rod in said head rail for operating said ladder tapes, and said lift elements;
at least two combined tilt and lift controls having hollow drum means for securing and operating said ladder tapes and lift element opening means defined by said drum means;
lift bearing means within said drum means;
lift reel means defining body means rotatably mounted in said bearing means within said drum means;
two way rotation control means mounted on said body means and within the interior of said drum means connecting between said lift reel means and said drum means, whereby operation of said tilt and control rod between predetermined limits will be transmitted to said drum means to cause movement of said ladder tapes and tilting of said slats, and wherein movement of said tilt and lift control rod beyond said limits, will release said lift reel means from said drum means and cause operation of said lift reel means independently of said drum means.
