What is a Venetian Blind?

Venetian blinds are window blinds made of horizontal slats. The name ‘Venetian’ comes from their place of origin which is predictable, Venice in Italy. They date back to as early as 1794 when they were used to replace curtains and shutters. Over the years they have evolved further, become more practical and versatile to meet the changing needs and preferences of homeowners around the world. Venetian blinds can be made of wood, aluminum metal, fabric and even vinyl plastic. Each of these materials has different functionalities. For example, aluminum Venetian blinds are a great choice for high humid zones like bathrooms and kitchen where wood and fabric will perish. If you are looking for aesthetics and appearance we recommend wood as they bring a natural and organic feel to the windows. Vinyl Venetian Blinds are easy to maintain and clean. Fabric Venetian Blinds have a classic and elegant feel and add a soft luxurious appeal to the rooms. It is this long-lasting appeal and beauty that has allowed Venetian Blinds to survive competition from the more modern window treatments.

How Do Venetian Blinds Work?

So how do Venetian Blinds work? The operational mechanism of Venetian blinds is no rocket science. The basic physics is same as any other cord and pulley blinds system. They are operated by hand to raise and lower the blind with a cord, and then the blinds can also be tilted with either a wand or a cord.

Structure of Venetian Blinds

Before jumping into the mechanism of the blinds it is important to understand the basic structure of the Venetian Blinds. Venetian blinds consist of slats made of wood, aluminum or plastic. These slats are drawn up or down by means of a pulley system that remains in the top casing of the blind attached to the top of the window frame. These slats are movable meaning that they can be opened outwards or inwards or remain completely closed. The cord lock mechanism remains concealed in the top casing and this allows you to pull the blinds up or down or keep them in a stack at the top. The lower edge is attached to the entire blind with the help of two pulling cords.

How Does the Slat Tilt Mechanism Work?

Venetian Blinds come with slats and each slat has holes perforated into them about 4 to 6 inches from the end. The lifting thread passes through these holes. Two outer threads along with the horizontal linking thread or clip between each slat help to form the ladder. This is linked to the tilting wand and the latter helps to turn the slats clockwise or anti-clockwise to angle them the way you want.

What is the Cord Lock Mechanism?

Hidden in the top casing is the brake mechanism. When you try pulling the cord diagonally across the front of the blinds, this mechanism helps to hold the cords to keep the slats in place at whichever height you want them to be. If you want to release the brake just hold the lopped cord across the blind and then pull gently to disengage the brake. The cords run through the top casing of the blind and lower and raise the blind as needed.

Cord Safety Measures

So now you know the structure and mechanism of your Venetian Blinds. It is simple but important to know the parts for your future reference if your blinds run into operational issues. As these blinds are corded it is also important to know about cord safety particularly if you have toddlers or pets in the house. As these cords keep dangling by the side of the windows, pets and kids often find themselves tangled in them. These have had fatal consequences in the past hence it is important to keep in mind the cord safety rules. You can screw a cleat high up on the window frame and get your cords wound around it to keep them out of the reach of children and pets. You can also cut the loop so that you have two ends to prevent strangulation. Ensure that the ends are long enough to hang without getting lost by being drawn up into the casing.
