The ancient Egyptians, who originally invented blinds, incorporated the basic function of tilting through the use of pulleys. Due to the then intricate design of the blind, which increased the price of the product, blinds were not widely used. If this story is to be believed, then this article is a must read. Blinds are believed to have been invented at a later time as a way to control sunlight, which is why they are thought to be superior to shades due to their greater functionality. For this reason, the ancient pharaohs cannot be credited with inventing blinds.

However, blinds are a curious machine. The basic function of a blind is to block light and provide privacy. To do that, they need to be adjustable. Adjustability is what makes blinds different. Basic window blocking can be done with paper, cloth sheets, or other permanent or removable coverings. However, if an occupant wants to adjust the level of privacy or allow some light into the room, they can use a blind to do this.

Blinds are generally available in both horizontal and vertical designs, so they are tailored to the particular requirements of the window or door to be covered. Controls are integrated to perform the open and tilt functions of modern blinds and are also available in a multitude of colors and sizes to suit all applications. All blinds, regardless of origin, must perform these functions to meet consumer demand and specific requirements. In short, similar functions are found in all blinds regardless of their origin. Only the quality of the components will dictate the smoothness of operation and reliability of the shutter.

As mentioned above, all blinds usually have two functions: tilt and raise. In the case of vertical blinds, the raise function is replaced by the traverse/open function. The end result of these operational functions is to adjust incoming light, control privacy, or fully expose the covered opening. All blinds perform similar functions thus giving the consumer the preferred function at a specific time.

In the case of horizontal blinds, metal mini-blinds available in horizontal slats in different sizes, wood or imitation wood slats also available in different sizes, the operating components are essentially the same, only the quality and design of such components will increase the reliability and ease. operation of the blinds.

The same element applies to most vertical blinds. There are some systems that work a little differently, but in the end, a vertical blind is a vertical blind.

To explain the functions of a vertical or horizontal blind, it is necessary to visualize the product itself in our mind. In the case of a vertical louver, carriers running on a custom made track will vertically support the vertical slats, which can be ordered in solid PVC or hanging fabric with a weight inserted into the bottom of each vertical slat to force fabric vertical blind to hang straight. These conveyors are interlocked and operate smoothly whenever they are rotated open to a desired angle or opened transversely, either partially or fully, as desired by the end user. In the case of a horizontal blind, regardless of the material used (real wood or imitation wood), the tilt and lift functions are performed through the use of cords and/or rods. The most popular systems are operated using cables for two reasons: ease of operation and aesthetics.

The tilt function of a horizontal louver or a vertical louver is accomplished through the use of a tilt mechanism built into the louver. This tilt mechanism involves the use of a gear drive that causes the shade to rotate/tilt to the desired position to allow the operator to control the amount of light entering a room, set the desired level of privacy, or control the level of outdoor lighting. view. The lifting function of a horizontal louver is accomplished through the use of a locking cord that allows the operator to lock the horizontal louver in the desired position. In the case of a vertical blind, the transversal function is achieved by means of a cord that goes through the brackets to the desired point.

Although the basic functions of shades remain essentially the same, in an effort to differentiate their products, certain manufacturers offer “upgrades” to their specific products, such as single-lever controls, plastic or metal chains, plastic or metal weights, roller designs, valances and bottom rails etc. However, these improvements generally increase production and sales costs and have little to do with the basic functionality of the horizontal louver or vertical louver.

The basic elements of blinds are the same between various systems. If one needs to repair a blind, it’s usually best to try to work with a retailer, who can determine if the blinds are repairable. In many cases, the blinds are so out of date that they can be a risk to the security of homes. However, if you will repair your blinds, at least you will be able to understand how they work.
