Abstract
A venetian blind having a top position lock wherein a pull cord extends over and depends from a cord guide between the latter and a freely upwardly shiftable jam member which engages the depending pull cord. The pull cord urges the jam member downwardly away from the guide upon upward slat movement, and the pull cord urges the jam member upwardly into jammed engagement with the cord guide upon downward slat movement. Detent means holds the jam member downwardly except in the top slat position, so that jamming action only occurs with the slats fully raised.
