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, per French windows and similar windows/doors/shutters.
  • the blind, object of the present invention is therefore inserted in the industrial field of the production of windows/doors/shutters, i.e. also in the field of the production of fabrics for sun protection, in the field of mosquito netting or of similar applications.
  • Blinds are known on the market for closing openings of windows/doors/shutters (such as windows, doors or French windows) provided with a rolling-shutter box, which is fixed to a building wall or to an upright that is lateral with respect to 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.
  • windows/doors/shutters such as windows, doors or French windows
  • a rolling-shutter box which is fixed to a building wall or to an upright that is lateral with respect to 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 susceptible of being gripped by a user and 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 comprises an aluminum section closed at the upper and lower ends by two terminations slidably coupled to 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 face each other and delimit the two sides of the opening to be closed with the windable fabric.
  • 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, e.g. up to the closed position, in which the fabric is placed to completely cover 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 exactly at the midpoint of its height but in a non-centered position, e.g. in proximity to one of the ends thereof. Such circumstance implies that the handle bar is more greatly moved along the guide closest to where the handle bar has been gripped by the user and to a lesser extent along the guide further away from where the handle bar has been gripped by the user.
  • fabric roller blinds also of known type, have been developed 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.
  • the fabric roller is constituted by an anti-mosquito net, with substantially rectangular shape, which is fixed at a 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 fabric roller blind of known type described in this patent EP 2530236 comprises a guide chain 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 aligned in succession - a member that is rigid in the opposite rotation direction, 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 windowsill) which delimits the opening to be screened, thus acting as 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.
  • Such fabric roller blind of known type also comprises, as stated, means for aligning the terminals of the handle bar in order to remedy their vertical non-alignment, or a different sliding in the horizontal direction of the two terminals, even if the handle bar is gripped and driven in proximity to one of the ends thereof.
  • the alignment means comprise an upper flexible element and an intermediate flexible element.
  • the upper flexible element consists of a flexible metal strap with curved section placed in proximity to upper rectilinear guide, fixed on one side to the vertical upright and fixed on the other side to the intermediate flexible element.
  • the intermediate flexible element consists of a flexible metal strap, which is fixed on one side to the guide chain and on the other side is fixed to the upper flexible element by means of a movable carriage.
  • the upper flexible element and the intermediate flexible element are both fixed to the movable carriage and the latter is slidably inserted within a vertical rail made within the handle bar, substantially parallel to the vertical seat for the elements of the guide chain.
  • the upper flexible element and the intermediate flexible element are both susceptible of rotating around a transmission pulley pivoted within the handle bar around a horizontal rotation axis that is transverse to the lying plane of the fabric, with the handle bar in closed position.
  • the movable carriage slides along the vertical rail made within the handle bar, allowing the handle bar itself to be moved between the open position and the closed position.
  • Such metal strap along with the guide chain when 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 backward, i.e. to remain back with respect to the lower terminal.
  • the main drawback lies in the fact that the means for aligning the blind of the above-described type are complex to make and install and consequently involve high production and installation costs.
  • a further drawback lies in the fact that the vertical rail in which the movable carriage - on which the upper and intermediate flexible elements are fixed - is slidably inserted considerably increases the total size of the handle bar, which is bulky and aesthetically not particularly agreeable.
  • a further drawback of the fabric roller blind of known type lies in the fact that the movable carriage moved within the vertical rail made within the handle bar is susceptible of being blocked and/or jammed within the vertical rail itself, due to possible non-alignments or an erroneous movement of the handle bar by the user.
  • the problem underlying the present invention is to provide a fabric roller blind, which is structurally simple and inexpensive to make and install and which therefore has limited production and installation costs.
  • a further object of the present invention is to provide a fabric roller blind which is provided with a handle bar provided with a limited bulk, which is also aesthetically pleasing the eyes of the user.
  • a further object of the present invention is to provide a fabric roller blind which is entirely reliable in operation and does not involve risks of blocking and/or jamming.
  • 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 window/door/shutter, e.g. a window, a door or a French door, made in a load-bearing structure such as the building wall of a building.
  • a window/door/shutter e.g. a window, a door or a French door
  • the fabric roller blind, object of the present invention comprises a support frame 2 provided with at least one lateral upright 3 and intended to be fixed to the load-bearing structure in which the opening A is made, which is advantageously defined at least between two lateral walls, an upper wall and a lower wall.
  • the support frame 2 can be fixed to the load-bearing structure at the opening by embedding it within the masonry or wooden section, or fixed with front mounting on the internal or external face of the building wall in which the opening is made.
  • the lateral upright 3 of the support frame 2 comprises a rolling-shutter box 39 intended to be laterally positioned with respect to the opening A to be screened.
  • the rolling-shutter box 39 comprises a hollow tubular body, in particular obtained with an aluminum extrusion, which is extended with substantially vertical axis between two opposite upper and lower ends.
  • the blind 1 also comprises at least one take-up roller 4 having a substantially vertical rotation axis X and rotatably connected to the lateral upright 3 of the support frame 2 and preferably housed within the rolling-shutter box 39.
  • the blind 1, object of the present, invention also comprises at least one 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 intended for making a shading screen, e.g. in substitution of a rolling shutter, of a brise North screen for filtering the solar light or for making a mosquito netting.
  • the fabric 5 can be dedicated to closing the opening of a window/door/shutter in order to protect an internal area from the sun and/or from the wind and/or, more generally, from the atmospheric conditions of the outside environment.
  • the fabric 5 as a function of its different applications, can be made of synthetic or natural material fabric and can have the shape of a mesh in order to prevent the entrance of insects or have a continuous surface of shading, filtering or transparent type.
  • the fabric 5 wound around the take-up roller 4 advantageously 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 at least one handle bar 6, to which the second lateral edge of the fabric 5 is fixed.
  • Such handle bar 6 is advantageously extended along an extension axis Z substantially parallel to the rotation axis X of the take-up roller 4 between a lower terminal 40 and an upper terminal 18.
  • the handle bar 6 is made with a hollow tubular body, in particular obtained with an aluminum extrusion.
  • the handle bar 6 is internally provided with at least one vertical seat, in particular made within the aluminum extrusion, and is extended along the extension axis Z starting from the lower terminal 40.
  • the handle bar 6 is movable between at least one open position, in which the handle bar 6 is placed in a proximal position with respect to the take-up roller 4 at least partially freeing the opening A of the fabric 5, and at least one closed position, in which the handle bar 6 is placed in a distal position with respect to the take-up roller 4 with the fabric 5 at least partially covering the opening A.
  • a second lateral upright 41 is advantageously provided, arranged on a lateral wall which defines the opening A, in a position facing the lateral upright 21 with the rolling-shutter box 3 associated therewith.
  • the handle bar 6 is mechanically associated with such second lateral upright 41 when it reaches closed position.
  • Such second lateral upright 41 advantageously also arranges locking/unlocking means (not illustrated in the enclosed figures) for stopping the handle bar 6 in closed position or for releasing it so as to allow the return thereof in open position.
  • the blind 1 also comprises at least one guide chain 7 susceptible of being extended below the fabric 5, so as to guide the lower edge of the fabric 5 itself during the movement of the handle bar 6 between the open position and the closed position.
  • the guide chain 7 is movable between a retracted position, in which it is housed within the vertical seat of the handle bar 6 with the handle bar 6 in open position, and an extended position in which it is unwound below the fabric 5 with the handle bar 6 in closed position.
  • the guide chain 7 comprises a plurality of aligned guide elements 42 that are mechanically connected to each other.
  • each guide element 42 of the guide chain 7 is on one side provided with at least one pin and on the other side is provided with at least one recess, shaped for containing the corresponding pin of an adjacent guide element 42.
