Claims

1. A system for suspension of banners characterised in that the system comprises a plurality of flexible attachment means corresponding to the number of attachment points on tire banner; a plurality of sheaves, said sheaves defines the attachment points of a geometrical figure; said geometrical figure is situated in a single plane; - a plurality of wires for stretching the banner, said number of wires equals the number of sheaves; said wires are at a first end attached to the flexible means, said wires at a second end interacts with at least one winch; said at least one winch is capable of tightening and loosening the wires thereby suspending the banner into a plane parallel with the single plane of the geometrical figure; each wire interact with at least one sheave between the first and second end of the wire said winch comprises an axis of rotation, said axis of rotation is perpendicular to the single plane said winch is situated in the single plane.

2. A system for suspension of banners according to claim 1 characterised in that the geometrical figure is a quadrangle, preferably a rectangle.

3. A system for suspension of banners according to claim 2 characterised in that - the banner comprises a first horizontal length and a first vertical length; the geometrical figure comprises a second horizontal length and a second vertical length; - half of a difference between the second horizontal length and the first horizontal length defines a horizontal distance; half of a difference between the second vertical length and the first vertical length defines a vertical distance; the horizontal distance and the vertical distance defines sides of a right-angled triangle whereby a hypotenuse can be calculated; the winch is situated at a distance from the geometrical figure; a length of a first wire engaging with a first sheave and attaching to a first attachment point at the upper left corner of the banner is defined by the sum of the second vertical length, the hypotenuse, the distance to the winch, and a slacking distance for the loosening and tightening of tire wire; a length of a second wire engaging with the first sheave and a second sheave and attaching to a second attacliment point at the lower left comer of the banner is defined by the sum of twice the second vertical length, tire hypotenuse, the distance to the winch, and a slacking distance for the loosening and tightening of the wire; a length of a third wire engaging with the first sheave and a third sheave and attaching to an third attachment point at the upper right comer of the banner is defined by the sum of the second vertical length, the second horizontal length, the hypotenuse, the distance to the winch, and a slacking distance for the loosening and tightening of the wire; a length of a fourth wire engaging with the first, third and a fourth sheave and attaching to a fourth attachment point at the lower left corner of the banner is defined by the sum of twice second vertical length, the second horizontal length, the hypotenuse, the distance to the winch, and a slacking distance for the loosening and tightening of the wire;

4. A system for suspension of banners according to claim 3 characterised in that the system comprises a calculation routine for finding the length of each wire using the first horizontal length, the first vertical length, the second horizontal length, the second vertical length, the horizontal distance, the vertical distance, the distance to the winch, the hypotenuse, and a slacking distance for the loosening and tightening of the wires to the calculation routine.

5. A system for suspension of banners according to any of the preceding claims characterised in that each sheave comprises an outer housing and a means for rotation, said means for rotation comprises an axis of rotation, said axis of rotation is perpendicular to the single plane said means for rotation interacts with one or more wires defining a path of the wires; said outer housing comprises a longitudinal axis said longitudinal axis defines an angle to the vertical axis of the single plan; said angle is defined by the path of the wires; - said path defines that said one or more wires only interacts wilh said means for rotation during tightening of one or more wires.

6. A system for suspension of banners according to any of the preceding claims characterised in that the second end of all the wires are combined by means of attachment with one single wire, said single wire engages with a winch, preferably the means of attachment is a snap hook.

7. A system for suspension of banners according to any of the preceding claims characterised in that the winch comprises means for automatically tightening and loosening the wires.

8. A system for suspension of banners according to any of the preceding claims characterised in that the flexible attachment means comprise at least one snap hook.

9. A system for suspension of banners according to any of the preceding claims characterised in that the wires comprises a metal core coated with an additional material, preferably plastic.

10. A system for suspension of banners according to any of die preceding claims characterised in that the sheaves are mounted on a wall.

11. A method for suspension of banners according to any of the preceding claims comprising the steps of mounting sheaves at attachment points of a geometrical figure defined in a single plane; mounting a winch at a distance from the geometrical figure; said winch comprises an axis of rotation; said axis of rotation is perpendicular to the single plane; said winch is situated in the single plane engaging a second end of each wire with the winch engaging the wires with at least one sheave engaging a first end of each wire with at least one flexible means - attaching the flexible means to a banner activating the winch for tightening the wires, hereby tightening the banner into a plane parallel with the single plane defined by the geometrical figure.
