Definitions

  • the present invention relates to a device for anchoring the blind fabric to a roller-blind roller according to the characteristics set out in the preamble to the main claim.
  • roller blinds In the field of roller blinds, it is known practice to provide suitable means in the roller-blind roller to secure one end edge of the blind fabric to the outer casing of the roller, this anchorage being typically provided along a longitudinal generating line of the roller.
  • a known solution provides for the preparation in the roller of a channel-shaped seating extending longitudinally in the roller between its opposite axial ends and open at these ends and also capable of housing and retaining a securing element of cylindrical shape.
  • the latter is in turn housed in a pocket made in the blind fabric by folding one end side of the fabric so that the pocket and the securing element inserted into it are retained in the channel and can slide axially but cannot be removed in a transverse direction.
  • a disadvantage encountered in this known anchorage system lies in the fact that to remove the securing element (to replace the blind fabric, for example) it is necessary to take off at least one of the end stops of the blind provided at the axial ends of the roller, so as to slide this element axially until it is completely withdrawn from the channel.
  • This operation is particularly inconvenient in roller blinds where the roller is housed in a box structure, since removal involves taking off the roller-blind roller from and refitting it to the box structure of the blind.
  • the problem addressed by the present invention is that of making available a device for anchoring the blind fabric to the corresponding roller-blind roller structurally and functionally designed to overcome the troublesome limitations noted with reference to the known technology.
  • the number 1 indicates as a whole a device for removably anchoring the blind fabric 2 to a roller-blind roller 3 of a roller blind 4.
  • the device 1 comprises a securing element 1a arranged to be attached to a lateral edge 2a of the fabric and to be housed and retained in a seating 3a made in the roller-blind roller, as will be explained in detail further on in the description.
  • the securing element 1a comprises a hook appendage 5 which can be inserted frontally into the seating 3a in the roller, transversely to the direction of longitudinal development of the roller, indicated by X in the drawings.
  • the direction of frontal insertion is indicated by the arrow A in figure 2.
  • the hook appendage 5 has the form of a tooth-shaped section such as to ensure that it is retained in the seating 3a once it has been inserted into said seating and the fabric 2 is tensioned tangentially to the roller in the operation of unrolling from or rolling onto the roller.
  • the tooth-shaped section of the appendage 5 is formed by a first and a second wall 5a, 5b, converging at the vertex edge 5c of the toothed shape, which have a respective curved shape in cross-section.
  • the curved shapes in section of the walls 5a, 5b have a curvature with the concave side facing in the same direction, as shown in particular in figures 1 and 2.
  • the walls 5a, 5b are in turn connected to respective flanges 6a, 6b of the securing element 1a capable of contact with the outer casing of the roller when the hook appendage 5 is inserted into the connecting seating 3a in the roller.
  • the securing element 1a is advantageously produced as an extrusion of plastics material of bar-shaped form with thin walls of open shape with mainly longitudinal development (in the direction transverse to the hook section). In this way the hook portion 5 with tooth-shaped section characterizes the securing element transversely along its entire longitudinal development.
  • the securing element 1a In use, provision is made for the securing element 1a to be inserted frontally into the seating 3a in the roller in the direction of the arrow A until the hook section 5 is housed and retained inside the seating. In the fastened condition, the flanges 6a, 6b bear against corresponding surface portions of the outer casing of the roller, at an opening 3b in the seating 3a.
  • This seating provided in the roller may have a typical channel shape with a cavity of circular cross-section open at the opening 3b in the outer casing of the roller.
  • This form of the seating 3 may reflect the typical form provided in roller-blind rollers of the conventional type and designed to house and retain a cylindrical securing element 7 capable of sliding axially in the seating and housed in turn in a pocket 8 made in the fabric 2 of the blind.
  • Figure 3 shows such a solution embodied according to known technology.
  • the hook appendage 5 has been inserted frontally into the channel seating 3a, it remains hooked to and retained in the seating as soon as the fabric 2, previously attached firmly to the securing element 1a, is tensioned in the operation of rolling up or unrolling relative to the roller-blind roller (arrow B in figure 2). This tension is induced tangentially to the roller 3 at the edge 2a at which the fabric is attached to the securing element 1a.
  • the fabric is attached along a first area of surface strip extending from the free end of the flange 6a, indicated by the reference number 9.
  • the strip 9 is continued in a second surface area 10 which extends until it joins the wall 5a of the hook appendage 5.
  • the area 9 is advantageously produced with greater flexibility and softness characteristics relative to the second area 10. This difference in flexibility makes it easy to attach the edge 2a of the fabric 2, by sewing or welding for example, while maintaining sufficient rigidity in the remaining part of the securing element 1a for the hook function which it has to perform.
  • Said difference in flexibility between areas 9 and 10 is preferably produced by appropriate co-extrusion by using plastics materials having components with suitable differences.
  • the attachment of the fabric edge 2a to the strip 9 of the securing element makes it possible to limit the total thickness to be rolled up, reducing this compared with the provision in known solutions (in figure 3) in which the flap of fabric (also made using a double fold) at the seam is normally such as to generate unwanted recurring marks on the unrolled fabric.
  • the shape of the hook appendage 5 is designed to prevent it from coming out of the seating 3a, even where the fabric is unrolled entirely and is rolled up in reverse onto the roller, in the opposite direction to that of the arrow B in figure 2.
  • Figure 4 shows a schematic view of a roller blind in which the roller-blind roller 3 is fitted in a box structure 11 between two opposite end stops 11a, 11b.
  • the fabric 2 is secured to the roller-blind roller by inserting the securing element 1a frontally (in the direction of the arrows shown in figure 4) into the channel seating 3a provided on the casing of the roller, so that it is not necessary to remove either of the end stops 11a, 11b of the blind or the box structure.
  • the invention thus solves the problem addressed and achieves the advantages claimed above compared with known solutions.
