ABSTRACT:
A blind assembly having a frame entrapping a set of blinds. The frame has an integral track upon which tilt and height control mechanisms are slidably mounted. A height control mechanism is slidably mounted on a vertical portion of the track, and the blinds are raised and lowered by movement of this mechanism. The mechanism is connected to a lift cord retained within the track and hidden from the user's view. This mechanism further includes a spring lock to engage the track and lock the mechanism, and thus the blinds, in a stationary position. A tilt control mechanism is slidably mounted on a horizontal portion of the track, and the blinds are opened and closed by movement of this mechanism. The blinds are protected behind a pane of glass or clear plastic.
