Roller blind 'Technical field

The technical solution relates to a roller shutter made of polyester mesh fabric for frameless covering of openings in the walls of farm buildings, especially stable buildings providing a suitable microclimate for optimal breeding conditions and for shading windows and open spaces in both civil and residential buildings.

BACKGROUND OF THE INVENTION

Farm buildings, especially stable buildings made of traditional materials for covering openings in walls, i.e. windows and gates, use airtight materials i.e. glass, wood, plastic, metal, which are unsuitable in terms of ventilation and maintaining the stable microclimate. Ventilation is carried out by forced circulation using fans or chimneys. Fresh air inlet and exhaled air outlet are designed in points and not all over the area.

For residential and residential buildings, the existing materials for shading windows and open spaces are also made of airtight materials.

The essence of the technical solution

Said drawbacks are solved by the use of a roll-up roller comprising an alternately wound and unwound flat spatial structure of polyester silk fabric with PVC surface treatment, the mesh fabric having a suitable density to create and maintain the desired microclimate in the farm buildings and having sufficient strength to withstand impacts and at the same time it permits the exchange of air in the desired space by its breathability. The density * of the warp and the weft of a polyester silk mesh fabric with a PVC coating is such that a climate with the desired properties is created behind the protected space t.

Roller blind for frameless covering of openings in the walls of farm buildings and windows and spaces in residential and community buildings consists of an upper tube, control winding and unwinding mechanism, which can be an electric motor, worm gear with crank, tongue and roller blind with a retaining rod on the lower edge wherein the roller blind cover is formed from a polyester silk polyester fabric with a PVC finish.

The use of a roll-up roller blind with a polyester-polyester mesh fabric covering with PVC coating for covering wall openings in farm buildings, for covering windows and open spaces in residential and civic buildings advantageously allows perfect protection of protected areas from weather conditions, ie drafts, rain, snow and sun shading while permitting air exchange.

Description of the drawing in the drawing

Fig. 1 shows an example of a roller blind with a mesh fabric covering of polyester silk with a PVC finish.

Example of technical solution

A roller shutter consisting of an upper tube 1, an actuating mechanism 2, which may be an electric motor, a worm gear with a crank or a pen and a roller shutter cover 3 provided with a catch bar 4 at the lower edge. with PVC finish.

Industrial applicability

Roller shutter with polyester silk mesh fabric cover with PVC surface treatment is used in commercial buildings with high demands on indoor ventilation and on creation and maintenance of required microclimate in these indoor areas, especially in stable and storage buildings. It can also be used in residential and civic buildings as shading of windows and open spaces against sunlight
