## Abstract

A roller blinds structure, having a casing provided with side walls that define an inner chamber intended to house drive means linked to a blind or similar, and guide profiles able to be located at opposite ends of the casing, which are configured to guide the blind or similar, the guide profiles being intended to extend in a downward direction with respect to the positioning of the casing, including an attachment system to attach each one of the guide profiles and the casing. The attachment system includes a first interconnection member able to be coupled to one end of the casing by means of fixing means and a connector member able to be coupled to the first interconnection member by means of first releasable quick-fit means and able to be coupled to a respective guide profile by means of second releasable quick-fit means.

## Claims

### Claim 1

A roller blind structure comprising:
a casing made up of a plurality of side walls that define an inner chamber intended to incorporate drive means therein for use with a blind, and
guide profiles able to be located at opposite ends of the casing, which are configured to guide the blind,
wherein the guide profiles extend in a downward direction with respect to the positioning of the casing, including an attachment system to attach each one of the guide profiles and the casing,
wherein the attachment system is provided with a first interconnection member able to be coupled to an end of the casing by means of fixing means and a connector member able to be coupled to the first interconnection member by means of first releasable quick-fit means and able to be coupled to one of the guide profiles by means of second releasable quick-fit means, and
wherein the first releasable quick-fit means consist of a flexible retaining flange able to be fitted in a housing having shapes and dimensions complementary to the retaining flange, the housing being made in an upper region of the connector member.

### Claim 2 (depends on 1)

The roller blind structure according to claim 1, wherein the retaining flange includes an extension that protrudes outward through an open portion made in the first interconnection member.

### Claim 3 (depends on 1)

The roller blind structure according to claim 1, wherein the second releasable quick-fit means consists of a male extension able to be coupled to a female region present in one of the guide profiles.

### Claim 4 (depends on 1)

The roller blind structure according to claim 1, wherein a male extension includes steps that define an abutting surface intended to come into contact an upper edge of one of the guide profiles.

### Claim 5 (depends on 3)

The roller blind structure according to claim 3, wherein the male extension includes a threaded through orifice intended for the insertion of a threaded pin.

### Claim 6 (depends on 1)

The roller blind structure according to claim 1, wherein the fixing means comprise orifices made in the first interconnection member and housings made inside a body of the casing, the orifices and the housings in the body being configured to insert screw elements.

### Claim 7 (depends on 2)

The roller blind structure according to claim 2, wherein the first interconnection member includes an extension with a substantially smooth shape.

### Claim 8 (depends on 1)

The roller blind structure according to claim 1, wherein the first interconnection member includes a ramp section located below an extension configured to enable the release movement of the retaining flange.

### Claim 9 (depends on 1)

The roller blind structure according to claim 1, wherein the interconnection member is made from a single part of injection mouldable plastic material.
