Blind control having a narrow profile drive

A control module to control a window shade roll comprising;

• a housing disposed at one end of said window shade roll, said housing having a control end wall, a shell plate and a first cavity and a second cavity, said first cavity communicating with said second cavity;
• a spur gear disposed in said first cavity between said control end wall and shell plate, to define a gap distance between said shell plate and said control end wall, said spur gear adjacent said one end of said window shade roll;
• a clutch projecting from said spur gear into said window shade roll, said spur gear rotatable with said clutch about a clutch axis for raising and lowering a window shade from said window shade roll;
• drive gear means disposed in said second cavity and engageable with said spur gear for rotatably driving said clutch about said clutch axis for raising and lowering said window shade;
• wherein said
• wherein said drive gear means in said second cavity is positioned axially inward from said one end of said window shade such that the shell plate and drive means overlap a face of the window shade and the drive means housed in said second cavity is axially spaced inward from the first cavity;
• a rod connected to said drive gear means to rotatably drive said spur gear.

A control module to control a window shade comprising;

• a housing having an end wall and a shell plate;
• a driven gear means disposed within said housing between said shell plate and said end wall, said driven gear means adjacent one end of said window shade;
• drive means disposed within said housing and engageable with said window shade for rotatably driving the driven gear means so as to raise and lower said window shade relative the opening;
• wherein said drive means is positioned inward from said end wall and overlaps said one end of said window shade;
• and
• a wand for driving said drive means;
• said wand including a shaft defining two intersecting spiral grooves and a hand portion coaxially receiving said shaft for reciprocal movement of said hand portion relative said shaft to rotate said wand, and a selector carried on said hand portion to selectively switch the rotation of said shaft in a selected first or second direction;
• wherein said selector allows engagement into a specific spiral groove of the two intersecting spiral grooves in order to select the specific direction of the rotation of the wand.

• a driven gear means disposed within said housing between said shell plate and said end wall, said driven gear means adjacent one end of said window shade;
• drive means disposed within said housing and engageable with said window shade for rotatably driving the driven gear means so as to raise and lower said window shade relative the opening;
• wherein said drive means is positioned inward from said end wall and overlaps said one end of said window shade;
• and a rod for driving said drive means;
• wherein said rod comprises a shaft defining two spiral intersecting grooves or two spiral intersecting protrusions and a hand portion coaxially receiving said two intersecting spiral grooves or two intersecting spiral protrusions for reciprocal movement of said hand portion relative said two intersecting spiral grooves or two intersecting spiral protrusions to rotate said shaft in a selected first or second direction to lower or raise said window shade and a selector on said hand portion to selectively switch the rotation of said shaft;
• wherein said selector allows engagement with a specific spiral groove or specific spiral protrusions of the two intersecting spiral grooves or two spiral intersecting protrusions in order to select the specific direction of the rotation of the wand.

A wand for attachment to a window shade assembly comprising;

• a) a shaft defining two spiral intersecting grooves or two spiral intersecting protrusions and a hand pumping portion coaxially receiving said two intersecting spiral grooves or two intersecting spiral protrusions for reciprocal movement of said hand pumping portion relative said two intersecting spiral grooves or two intersecting spiral protrusions to rotate said shaft in a selected first or second direction to lower or raise said window shade;
• b) wherein a first end of said shaft includes an attachment to attach said shaft to a control module and a second end of said shaft includes a hand grasping portion with said hand pumping portion disposed coaxially on the shaft for reciprocal movement between said first and second end;
• and
• c) wherein each:
• i) said groove is defined by two spaced groove side walls extending radially outwardly from said shaft, each said spaced groove side walls having a bottom edge and top edge and the space between the top edge of each said spaced groove side walls is greater than the space between the bottom edge of each said spaced groove side walls;
• or
• ii) said protrusions is defined by two spaced opposite protrusion side walls extending radially outwardly from said shaft, each said spaced opposite protrusion side walls having a bottom edge and top edge and the space between the top edge of each said spaced opposite protrusion side walls being less than the space between the bottom edge of each said spaced opposite protrusion side walls.
