Device for controlling opening and closing of window blinds

A system comprising:

• window blinds connected to a headrail comprising a tilting mechanism for opening and closing the window blinds;
• and
• a device for controlling opening and closing of the window blinds, wherein the device is secured to the headrail and comprises:
• a clamping module comprising:
• an upper clamp member engaging an upper surface of the headrail;
• and
• a lower clamp member movably coupled to the upper clamp member and engaging a lower surface of the headrail;
• and
• a drive module coupled to the clamping module and comprising:
• an actuator connected to the tilting mechanism;
• and
• a drive mechanism operatively coupled to the actuator and configured to drive movement of the actuator so as to open or close the window blinds.

A kit of parts comprising:

• a clamping module for securing to a headrail of a window blind system, the clamping module comprising:
• an upper clamp member for engaging an upper surface of the headrail;
• and
• a lower clamp member for engaging a lower surface of the headrail, and
• wherein the upper clamp member and the lower clamp member are movably coupled to each other so as to enable clamping of the headrail by the upper clamp member and the lower clamp member;
• and
• a drive module for coupling to the clamping module and comprising:
• an actuator for connecting to a tilting mechanism of the window blind system;
• and
• a drive mechanism operatively coupled to the actuator and configured to drive movement of the actuator such that the tilting mechanism is operated when connected to the actuator.
