Definitions

  • the invention relates to a roller blind, in particular for windows and doors.
  • the invention further relates to a safety device for stopping the moving roller blind when it encounters an obstacle when lowering or closing.
  • the same device also serves as an end stop when the roller blind is completely closed.
  • roller blinds which have strips made of wood, light metal or plastic material and which are articulated and can be rolled up onto a shaft.
  • roller blind according to the invention excludes its disadvantages. These consist above all in the need for a considerably large space for storing the strips rolled up around the drum, which space requires boxes of a corresponding size and with expensive facilities, such as the ceiling or door for inspection.
  • the present invention further excludes a good portion of the high assembly costs inherent in the conventional units of this type. Instead of the diverse processes for assembling a plurality of individual parts, which are also extremely difficult to install in very tight spaces, the present invention allows assembly that is simple and efficient.
  • the present invention thus achieves the objectives described above and makes it possible to install the roller blind in narrow niches of a conventional type for slats.
  • the roller blind according to the invention is characterized in that the zigzag folding of the strips, 2 n instead of by lateral guides of the strips, takes place by means of elastic parts which are arranged between at least two adjacent strips.
  • 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 4 for the rotatable mounting of the displacement and reversing shaft 5 of the strips.
  • a stop which is described in detail below, is fixedly attached to the associated vertical profiles 1, in order to prevent the curtain from being lifted off the shaft excessively and to prevent the roller blind from being opened 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. Ps is clear that it is sufficient for a shaft with a circular cross section to have the polygonal cuts 6 in some places distributed along the shaft.
  • the strips are usually made of metal or plastic made of material and have a circular 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 elements are designed so that their assembly between adjacent strips is possible and at the same time to serve as a hinge between them, and this due to the presence in this connecting element of a bracket 8 which ensures the strips a mutual bending 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 strips Due to the sliding movement "s" of a bracket, the strips can come to rest under themselves when the roller blind is pulled all the way down. This allows a compact curtain to be formed and a complete blackout to maintain the space and, at the same time, to achieve good insulation between the street side and the window. If the curtain is partially raised, the strips move away from each other and form the gap "s" which ensures that light and air penetrate.
  • 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, a belt, a motor or another 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 strips move in a guided manner and along the vertical guides 1 'while they accumulate in room A when opened.
  • the strips are stored by superimposing them in a zigzag manner in the room or magazine A, for example two or three of them lying adjacent.
  • 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 one another by means of this extension 16 into each other, 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 pattern to form a package P of strips A moved down.
  • the extension 16 By moving in the corresponding hole 17 in the plug 15, the extension 16 ensures that the adjacent strips rest against each other 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 silent 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 technology 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 determined by the drive mechanism, for example by hand, takes place in the direction of the opening, ie 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 Me chanik in action.
  • 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.
  • the device 19 is shown in FIGS. 12, 13.
  • a socket is indicated at 22, in the wall of which four longitudinal grooves 23 are designed to engage in the catches, which consist of bodies formed with flat parallel surfaces, and in which the outwardly directed wall 24 'is inclined.
  • the drive mechanism of the roller blind which has already been mentioned, can be attached in the outermost part 27 of the pin 25.
  • the drivers 24 penetrate into the corresponding grooves 23, or they withdraw from them due to the action of an obstacle which is in the way when the roller blind is lowered, and this because of the inclined outer plane 24 'of the driver.
  • the safety device 19 serves as an end stop when the roller blind is completely closed.
  • a retaining ring 28 is also provided for the drivers, which has the projections 28 'associated with the grooves 23. If the ring 28 is inserted into the grooves 23 in the course of the assembly, the shaft 5 is released from the drive mechanism so that the assembly of the wall is facilitated.
  • the invention ensures a high level of security against any improper raising of the curtain and also provides security for people and things moving along the closing path, i.e. find yourself when lowering the curtain.
