CLAIMS

1 . A construction assembly for installing a roller blind or the like comprising two parallel guiding sets spaced at a predetermined distance, between which at the least a roller blind can be slid in a guided manner, the at the least roller blind being arranged in the upper part of the two guiding sets, and in which each of the guiding sets comprises:

an internally hollow outer profile that can be fastened to a vertical surface,

- an internally hollow inner profile that is arranged in the interior of the outer profile, the inner profile having dimensions such that it is insertable into a housing defined by the outer profile by means of a snap fit.

a retaining element configured to retain a longitudinal edge of the roller blind arranged longitudinally along the inner profile.

2. The construction assembly for installing a roller blind or the like according to claim 1 , wherein it comprises resilient means acting between the inner profile and the retaining element, such that it holds the retaining element in position inside the inner profile.

3. The construction assembly for installing a roller blind or the like according to claim 2, wherein the resilient means comprise at least one spring element provided with a rigid section and a resilient tongue section, the spring element being located in a cavity defined by an extension protruding from the inner face of the inner profile towards the interior.

4. The construction assembly for installing a roller blind or the like according to claim 2 wherein it comprises at least two spring elements housed in two different cavities of the inner profile.

5. The construction assembly for installing a roller blind or the like according to claim 1 , wherein the outer profile and the inner profile are each substantially "IT shaped.

6. The construction assembly for installing a roller blind or the like according to claim 1 , wherein the roller blind comprises a longitudinally arranged toothed area at the insertable edge of the retaining element.

7. The construction assembly for installing a roller blind or the like according to claim 1 , wherein it includes joining means for firmly attaching the outer profile and the inner profile.

8. The construction assembly for installing a roller blind or the like according to claim 7, wherein said joining means consist of holes made in the outer profile and the inner profile provided for inserting screw elements or the like.

9. The construction assembly for installing a roller blind or the like according to claim 1 , wherein the two guiding sets are joined at the top by a caisson provided for housing the roller blind when it is rolled up.

10. A construction assembly for installing a roller blind or the like comprising two parallel guiding sets spaced at a predetermined distance, between which a first roller blind can be slid in a guided manner, and two additional parallel guiding sets spaced at a predetermined distance, between which a second roller blind can be slid in a guided manner, each one of first and second roller blind being arranged in the upper part of the two guiding sets, wherein the first and second roller blind are extensible and in a parallel way between to each other, which each of the guiding sets comprises:

an internally hollow outer profile that can be fastened to a vertical surface,

an internally hollow inner profile that is arranged in the interior of the outer profile, the inner profile having dimensions such that it is insertable into a housing defined by the outer profile by means of a snap fit.

a retaining element configured to retain a longitudinal edge of the roller blind arranged longitudinally along the inner profile.

1 1 . The construction assembly for installing a roller blind or the like according to claim 10, wherein the first and the second roller blinds are mounted on independent rollers arranged apart, each one housed inside a caisson.

12. The construction assembly for installing a roller blind or the like according to claim 1 1 , wherein each end of each one of the rollers is mounted in a plate, being placed said plate inside of a horizontal caisson.

13. The construction assembly for installing a roller blind or the like according to claim 10, wherein it comprises resilient means acting between the inner profile and the retaining element, such that it holds the retaining element in position inside the inner profile.

14. The construction assembly for installing a roller blind or the like according to claim 13, wherein the resilient means comprise at least one spring element provided with a rigid section and a resilient tongue section, the spring element being located in a cavity defined by an extension protruding from the inner face of the inner profile towards the interior.

15. The construction assembly for installing a roller blind or the like according to claim 13, wherein it comprises at least two spring elements housed in two different cavities of the inner profile.

16. The construction assembly for installing a roller blind or the like according to claim 10, wherein the outer profile and the inner profile are each substantially "IT shaped.

17. The construction assembly for installing a roller blind or the like according to claim 10, wherein the roller blind comprises a longitudinally arranged toothed area at the insertable edge of the retaining element.

18. The construction assembly for installing a roller blind or the like according to claim 10, wherein it includes joining means for firmly attaching the outer profile and the inner profile.

19. The construction assembly for installing a roller blind or the like according to claim 18, wherein said joining means consist of holes made in the outer profile and the inner profile provided for inserting screw elements or the like.
