Description:
CONSTRUCTION ASSEMBLY FOR INSTALLING A ROLLER BLIND OR THE

LIKE

OBJECT OF THE INVENTION

The present application is for the registration of a construction assembly for installing a roller blind or the like.

More specifically the invention proposes the development of a construction assembly for installing a roller blind or the like comprising two parallel guiding sets spaced at a predetermined distance, between which a roller blind can be slid in a guided manner, being joined at the top by the roller blind in an embodiment provided with a caisson which is provided to house the roller blind when it is rolled up.

BACKGROUND OF THE INVENTION

There is a wide variety of roller blinds, shades and the like on the market which differ in several aspects, among which are those related to their structural configuration.

Construction assemblies for installing a roller blind or similar comprising two parallel guiding sets spaced at a predetermined distance, between which a roller blind can be slid in a guided manner are well known. Each of the sets comprises an elongated profile arranged vertically where it moves in a guided manner, this profile being fastened through conventional fastening means on a wall or vertical surface.

It has been observed, however, that in practice the inside walls of rooms, such as interior rooms, etc., may have imperfections meaning that they are not straight or leveled, etc., thus causing misalignment of the two guiding sets and consequently bringing about a malfunction of the blinds during the raising/lowering action or it may involve having to modify or carry out adjustments in the profiles of the lateral guides in order to adjust to the imperfections of the wall. This implies requiring longer time for the assembly operation of the blind construction assembly.

In addition, the applicant is currently unaware of the existence of an invention having all the characteristics described herein.

DESCRIPTION OF THE INVENTION

The present invention was developed with the aim of providing a construction assembly that constitutes a novelty within the field of application, and solves the disadvantages mentioned above while also contributing other additional advantages, which will become evident from the description provided below.

It is therefore an object of the present invention to provide a construction assembly for installing a roller blind or the like of the type comprising two parallel guiding sets spaced at a predetermined distance, between which a roller blind can be slid in a guided manner, the two guiding sets being for example, joined at the top by a caisson which is provided to house the roller blind when it is rolled up. In particular, the invention is characterized in that each of the guiding sets comprises the following parts:

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.

Due to these characteristics, it is possible to adjust the degree of inclination of the two sides of the guiding sets, in case there are irregularities on the surface of the wall on which the assembly is to be installed, by means of a construction arrangement that is relatively easy to carry out and install. Consequently, a malfunction of the roller blind during raising/lowering operations as well as having to install different profiles for each of the guiding sets is avoided. In other words, there is a possibility of having relative motion between the outer profile and the inner profile, this motion being angular and/or translational.

According to another aspect of the invention, the assembly comprises resilient means acting between the inner profile and the retaining element, such that they hold the retaining element in position inside the inner profile.

Preferably, 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.

More preferably, the resilient means comprise at least two spring elements, as described above, which are housed in two different cavities of the inner profile. While it is also worth mentioning that in each of the two cavities a plurality of spring elements may be arranged in a distanced manner and longitudinally along the length of the corresponding cavity. The number of spring elements will depend on the length of the roller blind.

Preferably, the outer profile and the inner profile are each substantially

"IT shaped.

Advantageously, the roller blind comprises a longitudinally arranged toothed area at the insertable edge of the retaining element.

According to another aspect of the invention, the construction assembly may include joining means in order to firmly attach the outer profile and the inner profile. Preferably, said joining means consist of holes made in the outer profile and the inner profile provided for inserting screw elements.

Other characteristics and advantages of the construction assembly, object of the present invention, will become clear in light of the description of a preferred, though non-exclusive, embodiment, which, by way of a non-limiting example, is illustrated in the accompanying drawings, wherein:
