ABSTRACT:
The window shade track hook carrier includes a body of plastic, metal, ceramic or the like which is adapted to slide or roll freely in a shade track and bear a depending shade hook which is adapted to extend out of an opening in the bottom or side of the track. The carrier body has a window shade cord passageway extending longitudinally therethrough for holding such cord in the track. The track passageway is preferably lined with slippery plastic, smooth metal or the like low friction material to reduce abrasion of the cord and facilitate relative movement of the carrier and cord in the track. In one embodiment the body has a pair of body-centering rotatable wheels of plastic or the like disposed on opposite sides of the body. In another embodiment, the body has a pair of low friction skids on opposite sides of the body. In a third embodiment, the body is cylindrical and solid, with a low friction exterior, curved sidewalls and flat front and rear. The carrier provides improved performance and protection of the window shade cord.
