Definitions

  • the present invention regards a fabric roller blind according to the preamble of the independent claim number 1.
  • the present fabric roller blind is intended to be advantageously employed for adjustably closing provided openings of building walls, in particular for windows, for doors, for French windows and similar doors/windows/shutters.
  • the fabric roller blind, object of the present patent is a blind or mosquito netting of the type with vertical handle bar which closes and opens the opening by means of a horizontal translation of the same handle bar.
  • the blind, object of the present invention is therefore inserted in the industrial field of production of doors/windows/shutters or also in the field of production of fabrics for sun protection, in the field of mosquito netting or of similar applications.
  • Blinds for closing openings of doors/windows/shutters are known on the market; these are provided with a rolling-shutter box, which is vertically fixed to a lateral upright of the building wall which defines the opening to be closed, and at its interior houses a roller on which a flexible cover fabric is susceptible of being wound and unwound.
  • the fabric usually has rectangular shape and is provided with a first lateral edge fixed to the roller and with a second lateral edge opposite the first lateral edge and fixed to a handle bar aimed to stretch the fabric itself during a movement thereof along a horizontal direction.
  • the blind comprises two guides arranged horizontally along the corresponding upper and lower walls which define the opening and to which the handle bar is slidably constrained.
  • the handle bar usually comprises an aluminum section, which is closed at its upper and lower ends by two terminations, which are slidably engaged in the respective horizontal guides.
  • each of the upper and lower horizontal guides is generally obtained by means of an aluminum section fixed to the upper or lower wall which defines the opening.
  • Each aluminum section of the two guides is provided with a longitudinal slit which is extended along the extension of the same section and which slidably houses at its interior the corresponding upper or lower terminal of the handle bar.
  • the slits of the two guides are facing and delimit two sides of the opening to be closed with the fabric roller.
  • the handle bar is movable by a user between an open position, in which it is side-by-side the rolling-shutter box with the fabric completely wound around the roller so as to free the opening to be screened, and a closed position in which the handle bar is side-by-side the opposite lateral wall, with the fabric substantially completely unwound from the roller and placed to close the opening.
  • the user grips the handle bar and drives it along the horizontal guides up to the desired position, for example up to the closed position, in which the fabric is placed to totally close the opening.
  • the upper and lower terminals of the handle bar respectively slide along the upper and lower guides.
  • a first drawback of the blinds of known type lies in the fact that for the movement of the handle bar between the open position and the closed position, the handle bar may be gripped not precisely at half its height but at a non-centered position, for example in proximity to one of its ends. Such circumstance involves that the handle bar is stressed to be more greatly moved along the guide closer to where the handle bar has been gripped by the user and to a lesser extent along the guide further from where the handle bar has been gripped by the user.
  • blinds with fabric roller have been developed, also of known type, which are provided with means for aligning the terminals of the handle bar which maintain the terminals thereof vertically aligned during the movement of the same handle bar between the open and closed positions.
  • Such means for aligning the terminals of the handle bar therefore allowing remedying a vertical non-alignment of the terminals, i.e. their different sliding in the direction also if the handle bar is gripped and driven in proximity to one of its ends.
  • the fabric roller is constituted by an anti-mosquito netting, with substantially regular shape, which is fixed at one lateral end thereof to the take-up roller which is housed within the vertical rolling-shutter box and at the other end is fixed to the handle bar, which is susceptible of being gripped by a user in order to move the blind between the open and closed positions.
  • the above-described fabric roller blind of known type comprises a guide chain (or "carriage” in the technical jargon of the field) composed of a plurality of elements pivoted to each other in succession and capable of rotating with respect to each other only in one rotation sense so as to attain - when extended and aligned in succession - a rigid member in the opposite rotation sense susceptible of attaining a guide for the fabric.
  • Such elements are housed within a corresponding vertical seat made within the handle bar when the blind is in open position.
  • the chain is constrained at one end thereof to the rolling-shutter box in which the take-up roller is housed, while the other end is slidably inserted within the vertical seat of the handle bar.
  • the guide chain When the blind is moved from the open position to the closed position, the guide chain is driven outside the vertical seat of the handle bar, being set on the lower wall (usually the floor or a window sill) which delimits the opening to be screened, thus acting as a lower guide for the fabric.
  • the guide chain with the blind in closed position, therefore defines a horizontal rectilinear guide for the fabric, which allows retaining it in the spread-out position to close the opening to be screened.
  • a fabric roller blind of the type described above which provides for the use of means for aligning the terminals of the handle bar.
  • alignment means for example comprise flexible cables arranged inside the handle bar and connected to the ends thereof in order to synchronize the advancement thereof during the unwinding of the chain. Due to such alignment means, even if one of the ends of the handle bar meets an obstacle, the handle bar is not tilted, always ensuring the correct vertical position.
  • the cables are pliable elements over time, which require periodic calibrations with the intervention of a specialized technician.
  • Such metal strip like the guide chain, which extended during the opening of the handle bar defines a rigid member in the sense that it does not allow the upper terminal to return back or stay behind with respect to the lower terminal.
  • the metal strap requires being produced to size and hence cannot be modified during installation in order to adapt it to the dimensions of the opening if, for example, the measurements were not correctly made. Therefore, in this case, in order to modify the height of the handle bar and/or the length of the metal strap, it is necessary to send the blind back to its place of production, or to a specialized laboratory, clearly with increased overall costs associated with this blind.
  • the above-described fabric roller blind of known type can be produced to size for each client, based on the measurements of the opening to be screened, since as stated it is not possible to easily vary the dimensions of the blind on the field, during installation, and therefore it is costly and requires long times to attain.
  • a further drawback of the blind of known type lies in the fact that the metal strap, with the handle bar in closed position, is at least partially visible by the user and might not be aesthetically pleasing.
  • blinds with fabric roller which have the general characteristics described above and comprise two guide chains, of which one is upper and one lower, which have one end connected at a same upright and the other slidable in the guide bar.
  • Such blinds with fabric roller of known type comprise means for aligning the terminals of the handle bar obtained by joining, with flexible cables, the ends of the two chains.
  • Such blinds have the same drawbacks as mentioned above of the blinds provided with a single guide chain.
  • the problem underlying the present invention is to provide a fabric roller blind which has a handle bar movable between a closed position and an open position, maintaining an optimal alignment between its upper and lower ends regardless of the position in which the handle bar is gripped by the user in order to move it.
  • a further object of the present invention is to provide a fabric roller blind, which can be adapted to an opening to be screened even during its installation, in a quick and easy manner.
  • Another object of the present invention is to provide a fabric roller blind, which is entirely reliable in operation, and in particular capable of ensuring the aforesaid alignment also after an extended use over the years, without requiring a periodic maintenance.
  • Another object of the present invention is to provide a fabric roller blind, which is entirely efficient in operation, and in particular capable of ensuring the correct alignment of the upper and lower ends of the handle bar also for handle bars with high extension, i.e. also for handle bars provided with an extension of over two meters.
  • Another object of the present invention is to provide a fabric roller blind, which is structurally simple and inexpensive to make and install.
  • reference number 1 overall indicates the fabric roller blind, object of the present invention.
  • the blind 1 is operatively employable for adjustably closing an opening A of a door/window/shutter, e.g. of a window, of a door or of a French window, made in a load-bearing structure such as the building wall of a building.
  • a door/window/shutter e.g. of a window, of a door or of a French window, made in a load-bearing structure such as the building wall of a building.
  • the fabric roller blind 1, object of the present invention comprises a support frame 2 intended to be fixed to the load-bearing structure in which the opening A is made.
  • the latter is defined at least between two lateral walls, an upper wall and a lower wall of the load-bearing structure of the building.
  • the support structure 2 comprises a lateral upright 21 and at least one lateral abutment element 22, opposite the lateral upright 21.
  • the lateral upright 21 of the support structure 2 directly comprises or defines a rolling-shutter box 3 intended to be positioned laterally with respect to the opening A to be screened.
  • the rolling-shutter box 3 is a hollow tubular section, in particular obtained with an aluminum extrusion, which is extended with substantially vertical axis between two opposite upper and lower ends.
  • the lateral abutment element 22 is part of the support structure and also constituted by a hollow tubular section, in particular obtained with an aluminum extrusion, which is extended parallel to the lateral upright 21 with substantially vertical axis between two opposite upper and lower ends.
  • the abutment element 22 can nevertheless also be obtained as an element not constituting part of the support structure 2 and for example constituted by the internal wall of the load-bearing structure of the building which defines the opening A for the blind, or by a coupling element for the pin 101' of the final ring of the upper guide chain 10 (specified hereinbelow).
  • Such coupling element which in this case defines the abutment element 22 can be fixed (e.g. screwed) directly on the aforesaid internal wall of the load-bearing structure of the building, or it can be fixed to the upper guide crosspiece 200 (introduced hereinbelow).
  • the abutment element 22 in accordance with the embodiment illustrated in the enclosed figures, constitutes a second lateral upright arranged to the side of the opening A in position facing the lateral upright 21, with the rolling-shutter box 3 associated therewith.
  • the blind 1 also comprises a take-up roller 4 having a substantially vertical rotation axis X, rotatably constrained to the lateral upright 21 of the support frame 2 and preferably housed within the rolling-shutter box 3.
  • the blind 1, object of the present invention also comprises a fabric 5, which preferably has rectangular shape and is extended between a first lateral edge thereof fixed to the take-up roller 4 and a second lateral edge thereof opposite the first lateral edge.
  • the fabric 5 can be defined for making a darkening screen, for example in substitution of a roller shutter, of a brise-soleil screen for filtering sunlight, or for making a mosquito netting.
  • the fabric 5 can be dedicated to closing the opening of a door/window/shutter in order to protect an internal area from the sun and/or from the wind and/or, more generally, from the weather conditions of the outside environment.
  • the fabric 5 as a function of its different applications, can be made of synthetic or natural fabric and can have the shape of a net or have a continuous surface of darkening, filtering or transparent type. If the fabric 5 is formed by a net, it could make a mosquito netting in order to prevent the entrance of insects through the opening A.
  • the fabric 5 wound around the take-up roller 4 passes through a vertical slit which is made on a lateral wall of the rolling-shutter box 3 which is directed towards the opening A.
  • the blind 1 also comprises a handle bar 6, which is fixed to the second lateral edge of the fabric 5.
  • handle bar 6 is extended along an extension axis Y substantially parallel to the rotation axis X of the take-up roller 4 between an upper termination 7 and a lower termination 8.
  • the handle bar 6 is provided with an internal axial cavity which is extended along its extension axis Z.
  • the handle bar 6 is made with a hollow tubular body, in particular made with an aluminum extrusion.
  • the handle bar 6 is movable between an open position, in which it is placed in proximal position with respect to the take-up roller 4, and in particular it is abutted against the rolling-shutter box 3, freeing the opening A of the fabric 5, and a closed position, in which the handle bar 6 is placed in distal position with respect to the take-up roller 4 in abutment against the lateral abutment element 22 with the fabric 5 which is spread to cover the opening A.
  • the handle bar 6 is associated with the lateral abutment element 22 i.e. with the second lateral upright when it reaches closed position.
  • Such lateral abutment element 22 advantageously also has locking/unlocking means for stopping the handle bar 6 in closed position or for releasing it so as to allow the return into open position.
  • the blind 1 also comprises synchronization means 9 for synchronizing the advancement of the terminations of the handle bar 6 during its movement between the open position and the closed position.
  • the aforesaid synchronization means 9 comprise an upper guide chain 10, susceptible of being extended at the top of the opening A of the load-bearing structure of the building and a lower guide chain 11 susceptible of being extended at the lower part of the opening A of the load-bearing structure of the building.
  • the upper guide chain 10 is provided with a first internal end 10A, which is housed inside the cavity of the handle bar 6 and is susceptible of sliding along it, and with a first external end 10B connected to the lateral abutment element 22 or to the upper margin 22A of the section which forms such lateral abutment element 22 in accordance with the embodiment of the enclosed figures.
  • the lower guide chain 11 is in turn provided with a second internal end 11A, which is housed inside the cavity of the handle bar 6 and is susceptible of sliding along it, and with a second external end 11B connected to the base 21A of the lateral upright 21.
  • the upper guide chain 10 enters into the handle bar 6 by being folded downward, i.e. defining a first concavity 12 directed towards the lateral abutment element 22.
  • the lower guide chain 11 enters into the handle bar 6, being folded upward with a second concavity 13 directed towards the lateral upright 21.
  • the first and the second internal ends 10A, 11A respectively of the upper guide chain 10 and of the lower guide chain 11 are mechanically connected to each other in order to be jointly moved within the handle bar 6 along its cavity.
  • the movements of the handle bar 6 occur by maintaining the two terminations 7 and 8 thereof always vertically aligned given that the two upper and lower guide chain portions, indicated in the drawings with 10' and 11', which are extended above and below the fabric 5, respectively between the upper terminal 7 of the handle bar 6 and the lateral abutment element 22 as well as between the lower terminal 8 of the handle bar 6 and the base of the lateral upright 21, are extended always for the distance that separates the same handle bar 6 respectively from the lateral abutment element 22 and from the lateral upright 21 and are extended in the form of axially rigid linear elements which thus set the constant verticality of the handle bar 6.
  • the horizontal portions 10', 11' of the two guide chains, upper 10 and lower 11, are as stated axially rigid linear elements which prevent the handle bar 6 from being moved away from the verticality.
  • the two upper 10 and lower 11 guide chains define, at any one intermediate position of the handle bar 6, a mirrored S progression with respect to a through axis for the handle bar 6, as can be appreciated in figure 1 .

  • the support structure can also provide for an upper guide crosspiece 200 and a lower guide crosspiece 201.
  • the upper guide crosspiece 200 acts as a guide for the upper termination 7 of the handle bar while the lower guide crosspiece 201 is constituted by a guide of thin thickness for the lower guide chain 11.
