Roller shade clutch with internal gearing

A clutch for operating a window dressing mounted on a stationary structure, comprising:

• an end member adapted for mounting the window dressing to the stationary structure, said end member receiving a cord adapted for manipulation by a user to operate the window dressing, said end member including a gear box adapted to translate a movement of said cord into a rotation at a preselected mechanical advantage, said gear box including a planetary gear rotated by the cord;
• an output member adapted to couple said rotation to the window dressing;
• and
• an antirotational member coupled to said output member to prevent undesirable rotation of said output member;
• wherein said end member includes a disc having an inner surface and wherein said gear box includes a fixed gear coupled to said inner surface, a gear pulley adapted to couple to the cord, a planetary gear coupled to said gear pulley and said fixed gear to move in a planetary motion when said gear pulley is rotating;
• said planetary gear being coupled to said output member to rotate said output member.

A bi-directional clutch for supporting a window dressing on a structure, said clutch comprising:

• a protective guard adapted to be secured to the structure and including a disk with a lip and a drum disposed coaxially on the disk;
• a drive having a boss and hub, said hub facing said lip to define a chamber, and said boss disposed telescopically over said drum;
• a tubular housing disposed telescopically over said boss and adapted to engage the window dressing;
• and
• a gear box disposed in said chamber, said gear box being coupled to an elongated operating member and adapted to transfer a rotation to said tubular housing when said elongated operating member is manipulated by the user.
