Definitions

  • the invention relates to a roller blind, in particular for windows and doors, with the features characterized in the preamble of claim 1.
  • Such a blind is known from CH-A-618 495.
  • at least two adjacent strips are connected by means of leaf springs which penetrate the inside of the strips.
  • the object of the present invention is to reduce a good part of the high assembly costs that are inherent in the conventional units of this type.
  • the roller blind comprises two side profiles 1 which are advantageously made of an aluminum alloy. Contrary to the conventional profiles which only represent a U, they have a structure and a construction which is so robust that they ensure the formation of a space A in the upper region of the profile for receiving the package P of the strips 2 folded in a zigzag shape.
  • the side profiles 1 support the support 3 for the package formed by the strips, as does the bearing point 4 for the rotatable mounting of the displacement and reversing shaft 5 of the strips.
  • a stop which is described in detail below, is attached with the associated vertical profiles 1 in order to prevent the curtain from being lifted off the shaft excessively and to secure it against the opening of the roller blind when it is not through the mechanism provided for this purpose is actuated.
  • the shaft 5 preferably has a polygonal cross section, in particular a square or a triangular cross section. It is clear that it is sufficient that a shaft with a circular cross-section has the polygonal cuts 6 in some places distributed along the shaft.
  • the strips are usually made of metal or plastic material and have a hollow cross section. It is possible to inject a suitable material into it, for example polyurethane foam, with the aim of increasing the insulating capacity and at the same time making it quieter in its displacement movement.
  • a suitable material for example polyurethane foam
  • the strips are pivotally connected to one another (FIGS. 5, 6) by means of articulated connecting elements 7, which are arranged in the vertical longitudinal direction of the roller blind, along two or more lines.
  • the connecting members are designed so that their assembly between adjacent strips is possible and to serve as a hinge between them at the same time, due to the presence in this connecting element of a bracket 8 which ensures a mutual bending of the strips by an angle of 270 °.
  • the same organ 7 is made of a rectangular lamella made of thin material, e.g. Spring material, obtained, which is bent at the top in 9 to form the bearing point for the two coaxial base lines 10, 11 of the flat bracket 8, which bracket itself is made of steel wire and is correspondingly shaped like an omega.
  • a rectangular lamella made of thin material, e.g. Spring material, obtained, which is bent at the top in 9 to form the bearing point for the two coaxial base lines 10, 11 of the flat bracket 8, which bracket itself is made of steel wire and is correspondingly shaped like an omega.
  • the opposite end of the bearing points is bent over to form an elongated and, in this, a displaceable bearing point for the upper cross member 13 of a corresponding, movable bracket 8 '.
  • the roller blind is opened and closed by rotation, in one direction or the other, of the shaft 5 already mentioned.
  • This can be driven using conventional means, for example with the aid of a winch, rhyme, motor or other means .
  • this serves as a driver of the strips, be it in the closing direction or in the opening direction of the roller blind.
  • the slats are stored by overlapping in space or magazine A, for example, two or three of them lying adjacent, accumulating.
  • the depth of the insertion is limited by a stop 14 'of the stopper, as a result of which the extension or extension 16 comes to lie outside the end face 2' of the strips.
  • the extension 16 is advantageously obtained in one piece with a first stopper 14.
  • the plugs engage with one another by means of this extension 16, which is made of elastic, consequently bendable material, and which extension penetrates into an associated hole 17 of an adjacent second plug 15.
  • the entirety of the stopper and the extension stiffens the strips enough below them, on the other hand forces the sequence of two subsequent strips to zigzag in relation to the preceding sequence, the desired package P being formed.
  • the flexibility of the extension allows the curtain of the roller blind to bend when it is subjected to a deflection movement on shaft 5, while it stiffens the adjacent strips of the curtain sufficiently when it folds into the space in a zigzag shape to form a package P of strips A moved down.
  • the extension 16 By moving in the corresponding hole 17 present in the plug 15, the extension 16 ensures that the adjacent strips rest against one another in order to form a closed curtain or to distance themselves from the aforementioned slots "s" for the passage of To get light and air. However, this displacement is determined by the already mentioned arc 8 'of the articulated connecting element 7.
  • plugs 14, 15 are made of plastic material and if they move in the straight, vertical guides 1 'they ensure a smooth and noiseless movement of the roller blind.
  • stop 18 If the stop 18 is at the correct distance from the axis of the shaft 5, then it ensures the ledges the guided passage when the shaft is actuated, while excluding this passage when the shaft is at a standstill.
  • This provides another advantage of the present invention, i.e. the security against an improper opening of the roller blind.
  • roller blind when the roller blind is lowered, it remains locked automatically without the use of complicated and expensive mechanisms, such as winches or the locks known from roller blinds.
  • connection of the shaft 5 (FIGS. 12, 13) with the mechanism for its actuation takes place through the intermediate arrangement, at one end of the drive shaft, of a device 19 which has a snap-in engagement.
  • the device 19 engages the shaft 5 and takes it with it when its rotation, which is caused by the drive mechanism e.g. is determined by hand in the direction of the opening, i.e. in the direction of lifting the roller blind; however, when the shaft 5 rotates in the direction of lowering or closing, the roller blind lowers due to its own weight, and the drive mechanism then, while rotating, takes over the task of controlling the lowering speed. In this case too, the mechanics remain in operation.
  • roller blind when the roller blind is completely closed or is about to lower, i.e. to close, and if the lowering movement intervenes, for example a person or some object and the drive mechanism is in motion, then the roller blind will block due to the device 19 even if the mentioned mechanism is turned further in the closing direction, so that Damage to people, things and the blind can be avoided.
