Definitions

  • the present invention relates to a roller shutter with orientable slats provided with a simplified means for angular rotation of the slats themselves.
  • roller shutter with orientable slats destined to allow the closure of doors and windows to form a barrier to the outside, provides for the movement of the slats themselves, unlike known solutions, to be carried out using an extremely reduced number of components, with a considerable advantage both from the production point of view due to the reduction in the number of components used, and from the point of view of product reliability.
  • the roller shutter according to the invention provides for each slat to be associated with a respective support called “slat holder” which is simultaneously connected to two elements of support and of transmission of the rotary motion called “chains". That is, each slat holder is connected to its corresponding chain and to the one located immediately above, thus avoiding any direct connection between the slats themselves.
  • the present invention finds application in the field of frames, doors and windows, shutters and blinds, which can be used mainly in the civil field, but also in the industrial sector.
  • a shutter is constituted by a plurality of horizontal sticks, or slats, joined together in a flexible way, so as to be able to wind on a roller located above the window frame in a compartment called "box".
  • the slats are oriented one at a time starting from the bottom following the progressive unwinding of the shutter, after it has rested on the threshold of the wall compartment in which the shutter itself is located.
  • This type of orientable shutter requires the use of additional profiles to support the slats and said profiles participate in the function of orientation of the slats, and this causes a certain limitation of the angle of orientation of the slats themselves, as this angle is produced by the connection between each slat and an additional curl-shaped profile located on each adjacent slat, since if a certain limit of the orientation angle were exceeded, the slats would be released.
  • the mechanism is made up of several elements such as link or chain elements which, combined with slat supports, arms and connecting rods, allow the simultaneous movement of the slats by means of a special kinematic mechanism.
  • the aforementioned kinematic mechanism is permanently mechanically connected to the winding roller. Consequently, with the shutter completely lowered, when the roller rotates in the unwinding direction of the curtain, the kinematic mechanism is set in motion which in turn transmits the motion to the arms and from them to the pins integral with the slat supports rigidly constrained to the slats which then rotate in angular orientation making a maximum angle greater than 90°, while when the roller rotates in the winding direction, the slats rotate in the direction opposite to the previous one until they close completely.
  • the slats are also provided with a compacting/decompacting function through devices that can distance or near the longitudinal edges of the slats.
  • the present invention aims to provide a roller shutter with orientable slats provided with a simplified means for angular rotation of the slats themselves, thus creating a condition which is capable of eliminating or at least reducing the drawbacks highlighted above.
  • the invention aims in particular to provide a roller shutter with orientable slats provided with a simplified means for the operation thereof, which is realised using a very limited number of components, so as to obtain a structure with contained production costs, extremely functional and characterised by a linear aesthetic effect as it has no visible mechanical parts and support profiles.
  • the limitation of the components used allows that there is not only no direct connection between the slats, but that there also exists no other connection by means of other extruded profiles.
  • the reference number 20 generally indicates a shutter as a whole comprising all the components thereof, the main of which are represented by a plurality of slats 21, hooked by ends thereof to a respective slat holder support 22, which is rotatably associated to a respective chain element 23, which chain element 23, together with further chain elements 23 consecutively connected to one another by the various slat holder supports 22, is inserted in a groove 24 formed on a vertical profile 25, positionable in the compartment of a window or a French window or another outward opening of a building.
  • each slat 21 is made using an elongated and particularly shaped profiled element comprising a central through cavity made in such a way that the two ends of each slat allow accommodating respective slat holder elements 22 which perform the function of respective closing caps and of support for the lifting, lowering and orientation operations of the slats of the shutter itself, for a total of two mirror supports for each slat, which are fixed on the same ends in order to remain constrained thereto.
  • each slat holder support 22 is configured according to the same profile of each slat and comprises a shaped projection 26 designed to be introduced into the central through cavity when the slat holder is applied by joint-fitting on the end of the respective slat, in such a way as to form a single body with the same.
  • each slat holder 22 superiorly comprises two pins 27 and 28 that are parallel to one another and arranged on the opposite side to the slat holder with respect to the profiled projection 26.
  • each chain element 23, as represented in Figures 15 to 19 is made with a body also having a shape that resembles the one of the slat holder 22, and is provided, at the two opposite ends thereof, with two holes arranged parallel, indicated respectively with 29 and 30, of which the first is lower and the second is higher.
  • each chain element 23 is destined to accommodate the upper pin 28 of the slat holder located on the lower slat, while the upper hole 30 accommodates the lower pin 27 of the slat holder located on the same level.
  • Each slat holder remains constrained to a pair of consecutive chain elements 23, with the possibility of angular rotation on the parallel axes of the pins 27 and 28, by screws 31 which are inserted passing through the holes in the pins 27 and 28 of the slat holders 22, to penetrate into channels 32 formed longitudinally in the profiled element of each slat 21 and to stably fix the same slat 21 to the respective slat holder 22.
  • the head of each screw 31 effectively prevents each slat holder from slipping off the respective chain elements 23 to which it is coupled, i.e. the corresponding one and the one immediately above.
  • the lower part of the shutter comprises compensation elements represented by profiles 33, 34 arranged parallel with respect to the slats 21, which constitute the lower terminal part of the curtain, and by respective lateral closing elements 35, 36.
  • the profile 33 is free to slide vertically inside the profile 34 with a travel that defines the space in which the user of the shutter can halt the unwinding of the curtain and obtain an intermediate condition of the shutter fully lowered, but with the slats closed.
  • the chain elements 23 are exclusively connected by means of the pins 27 and 28 present on the slat holder 22 and, consequently, each slat holder connects two chain elements 23, i.e. one being its own chain and one being the chain located immediately above.
  • slats 21 are fixed only on the respective slat holders 22 from which they take the motion, consequently there is no direct connection between the slats themselves, or by means of other profiles.
  • the pin 28 passes from a position overlying the position of the lower pin 27 (closed slats) to a position in which the upper pin is flanked to the lower pin 27 (oriented slats).
  • a too small width of the groove 24 could prevent all the travel of the pin 28 about the axis of the hole 30 causing an undesirable lower degree of orientation.
  • the aforementioned compensation system constituted by the profiles 33 and 34 which represent the lower terminal part of the curtain, and the respective lateral closing elements 35 and 36, has the function of allowing the user to easily identify the intermediate condition of the shutter in which the curtain is fully lowered, but all the slats are closed, that is not oriented.
  • the profile 33 results to be inserted in the profile 34 and has the possibility of sliding therein in a telescopic manner in a vertical direction.
  • the travel of the profile 33 in the profile 34 defines the space in which the user of the shutter can halt the unwinding of the curtain and obtain the aforementioned intermediate condition.
  • the further unwinding brings the profile 33 to rest on the bottom of the profile 34 with consequently unloading of the weight of the shutter on the threshold of the compartment in which it is placed with the effect that the force of gravity determined by the weight of the shutter is unloaded onto the pins 28 setting them in rotation about the axes of the holes 30 and of the pins 27 and by progressively causing all the slats to rotate.
