Latest Patents

David E Mattey holds a patent for a bottom stop mechanism for a window covering. This inventive mechanism utilizes one of the lift cords to operate effectively. As the cord unwinds from the shaft, it leaves the shaft along a line tangent to the shaft. When the last turn of the cord unwinds, the angle of the cord changes, which is crucial for the mechanism's operation. This change in angle raises a pawl that engages a ratchet wheel, stopping the shaft and preventing further rotation in that direction. When the shaft is reversed to wind the cord again, the angle returns to its prior value, releasing the stop.
