Abstract: The window shade lock device includes a handle having a round or elongated hand grip end and a slide connector extending forwardly thereof. The slide connector is pivotally secured, preferably off center, to the preferably generally rectangular body of a slide bearing four spaced, axled, rotatable wheels, two on each of two opposite sides thereof. The wheels are adapted to ride in parallel spaced channels in a window shade side frame. The wheels extend beyond the side margins of the slide body. The slide body extends out of the frame into connection with the connector front end outside the frame. The handle is pivotally movable up and down between a locked and unlocked position. When in the locked position the slide connector front end biases the slide, specifically the wheels thereof, tightly against the frame to hold the lock in position. In the unlocked position the slide connector front end biases and spaces the slide from the frame for free movement therein.

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.
