Louver Control Mechanism

摘要

The present invention provides a mechanism for controlling the spacing between louvers, e.g. in a blind. The louvers are secured to a top rail and a bottom rail. The connections are at an angle to each other so that the louvers are naturally twisted. The louvers extend through slots in a comb 16 that can be moved up and down the louvers. The function of the comb is to alter the position of the twist as it is moved up and down the louvers, thereby opening and closing the blind.

主权项

1. A mechanism comprising:
two or more flexible louvers configured to lie generally parallel to each other and each having a first end and a second end; and at least one comb comprising at least one slot that is shaped to hold a louver in it, which comb is capable of travelling along the length of said louver, wherein the slot has a different orientation to the louver at least one of its ends, whereby Moving the comb along the louver alters its configuration.
