Abstract

A blind formed of fabric has fabric slats or vanes 5 attached at their rear sides to a fabric/mesh panel 3. Vertical control straps 4 connect the slats at their front sides. The straps and fabric panel are connected to a roller 2 at the top, and the slats 5 can be opened or closed in Venetian blind fashion by rotating the roller 2 up to a quarter of a turn (see figures 9 & 10). The blind can be raised by further rotation of the roller, which causes the blind to wind around the drum in roller blind fashion (see figures 12-22). The fabric parts are preferably bonded together, e.g. using ultrasonic welding or glue bonding. The blind may be used as a window blind.

Description

Title;

Light Control Blinking Blind Fabric (LCBBF)

Background;

Venetian blinds are traditionally made from rigid plastic material in order to function. There is a need for a new design of a soft fabric formation. The LCBBF is a soft fabric designed to function as blinds without the need for rigid plastic material and chords requiring assembly.

Statement of Invention;

This invention is relating to a new fabric formation, consisting of a single fabric with other fabric pieces bonded in a way to enable the fabric to control light passing through and functioning as a blind.

The method of making blinds from soft fabric is limited. Manufacturers typically result in using plastic materials to produce blinds. The LCBBF is a functioning fabric as well as a new design and a method in controlling light. The fabric formation is made on an industrial scale by ultrasonic welding and not stitching.

Advantages:

Soft fabric is generally used for curtains with a limitation for using it in soft blinds. Soft fabric blinds are available as a Roman Blind design and 3-D double sided fabric to control the light passing between fabric panels. The LCBBF is a new and different method of controlling the light passing between the fabric panels using single mesh fabric with straps. The straps will control the movement of the Blink panels which are fabric pieces attached in a horizontal position on the mesh fabric. On a commercial scale the LCBBF is made by ultrasonic welding and not stitching providing commercial benefit of mass production to reduce costs. Traditional blinds require a complex assembly method which is time consuming, while the LCBBF is ready made from the manufacturer to be linked to the blind roller.

Description;

The LCBBF is specifically designed to function as a blind, and will control the light passing through by adjusting the movement of the fabric. The LCBBF is formed by one single mesh fabric, the Blinking Panels and the Control Straps. All pieces are ultrasonically welded, the Blinking Panel is welded from one side to the mesh in a horizontal position and the other side is welded to the Control Straps. The LCBBF will be moved and rolled by a standard blinds roller, which is attached and bonded, so when the roller rotates anticlockwise the LCBBF will be functioning in different stages. When the blind roller is positioned at a position of zero angle degrees, this position is situated with the Blinking Panels in a full open state, at a 90 degrees angle against the mesh fabric considered as a zero angle. When the roller blind rotates slowly anticlockwise the Blinking Panels will rotate equally in a harmonic rotation, this rotation will result in reducing the light shining through the mesh fabric, and when the roller blind completes an eighth of a revolution, the Blinking Panels will rotate to 45 degrees from the zero position, blocking 50% of the light shining through the mesh fabric, and when the roller blind completes a quarter of a revolution the light will be completely blocked result in moving the Blinking Panels downwards by 90 degrees from the original zero angle position and will be parallel and closed on the mesh fabric. When the roller blinds rotate further to complete a half revolution, the mesh fabric will move upwards and start to roll around the roller, and the LCBBF will be rolling around the blinds roller, and the more it is rolled the more fabric will be moving upward resulting in complete removal of the LCBBF fabric from covering the window to let full light through. The mechanism of the LCBBF is related to the quality and the accuracy of the ultrasonic welding creating an equal balance to allow all parts to move in harmony. The welded joins on the fabric will act as hinges to allow the Blinking Panels rotation to be smooth and effective.
