Description

The subject of the industrial design is a roller blind, intended primarily for covering windows. To achieve greater comfort in rooms, various types of roller blinds are used to cover windows and glass doors. Depending on the material from which they are made, they not only reduce the intensity of interior light but also prevent the room from heating up with sunlight or limit heat emission to the outside. The subject of the industrial design is presented in a photograph and a drawing, where Fig. 1 shows a view of the roller blind and Fig. 2 shows a cross-section of the casing profile. The roller blind consists of: a housing 1 made of a characteristic profile to which guides 2 are attached, in which the side edges of the cover 3 move, ending with a stiffening strip 4. The housing 1 contains inside a winding mechanism 5 activated by an outwardly extending chain 6. The housing 1 is closed at the ends with plastic endings 7 and 8. The housing 1 is made of an aluminum profile with a cross-section shown in Fig. 2. This is a cross-section close to a square, the lower wall 10 of which is shorter than the others and in the corner with the rear wall 11 it creates a gap 12. The remaining corners of the cross-section are cut to form oblique walls 13. An ornament can be placed on the front wall 9 of the housing 1. An important feature of the industrial design is that the housing 1 is made of an aluminum profile with a cross-section close to a square, the lower wall 10 of which is shorter than the others and in the corner with the rear wall 11 it creates a gap 12. The remaining corners of the cross-section are cut off to form oblique walls 13. Depending on the variant, the front wall 9 of the housing 1 can be decorated with an ornament or it can be smooth.
