ABSTRACT:
A wind-shield blind having a hollow spindle having a first end in which a tubular plug fits and a second end in which a second plug fits, a shaft inserted in the spindle through the tubular plug, a spring having a first end attached to a bifurcate end of the shaft and a second end attached to the tubular plug, a first terminal element connected with a flat end of the shaft, a second terminal element connected with the first terminal element by a connecting element, and a switch. The second plug has a ratchet from which a pole co-axially protrudes. The second terminal element has a wall surrounding a disk defining a slot, a ratchet, and a hole. The second plug is biased toward the second terminal element by the spring, thereby urging the ratchet of the second plug to engage with the ratchet of the second terminal element to retain an opaque film at any desired positions while the pole passes through the hole. A switch has a button from which a cylinder protrudes and defines a rim enclosing a smooth cavity. Two wedges laterally project from the cylinder of the switch and can be pressed through the slot, thereby allowing the switch to slid along the slot between a first position where the cavity contacts the pole, whereby the ratchets contact each other and a second position where the rim contacts the pole, whereby the ratchets are away from each other.
