Definitions
- the present invention relates to a roller shutter to reversibly close doors, windows or other building openings, capable of performing the functions of both a roll-up gate or roll-up shutter and a jalousie.
- roller shutters are known that are capable of performing the functions of both a roll-up gate or roll-up shutter and a jalousie.
- the author of the present invention has noted that these and other known roller shutters have a relatively complex, sometimes unreliable mechanical construction.
- the document DE1237289 describes a roller shutter wherein, when lowered, its own weight causes the opening of a plurality of blades so as to allow the passage of air and light, while when lifted, again by gravity, the blades close, mostly preventing the light from the outside from passing, being, on the other hand, less effective in preventing the passage of air.
- Each blade is fastened to a cross member extending horizontally along the entire width of the window or other opening to close, and may slide inside a lateral guide to lift or lower the roller shutter.
- these cross members uselessly reduce the visibility through the lowered roller shutter, that is when the blades are open; furthermore, they uselessly increase the cost of the roller shutter and, on the other hand, do not contribute in a significant way to preventing draughts and the passage of air when the roller shutter is lowered and the blades are closed.
- the document FR2966862 discloses a roller shutter able to work like a jalousie and provided with slats opened and closed through cam sliding over a driving track. A good operation of this device requires a careful choice of the coefficients of friction between the cams and said tracks.
- An object of the present invention is to overcome the drawbacks of the prior art mentioned hereinabove and, in particular, to provide a roller shutter having a relatively simple construction which, when working as a jalousie, provides a lower degree of obstruction to the view or the ventilation, and, when working as a roll-up shutter or blind, provides a greater degree of obstruction to air and/or light.
- FIG. 1-5 relate to a roller shutter according to a particular embodiment of the invention, indicated with overall numeral reference 1 and usable for example to reversibly close doors, windows or other apertures of buildings.
- the roller shutter 1 comprises:
- the driving chain 5 comprises a plurality of driving chain links 7 and a plurality of connecting chain links 9 articulated together - for example hinged
- At least some of the driving chain links 7 are fixed, link by link, to at least one respective slat 3 and are arranged to drive it in order to reversibly open and close a plurality of openings 11, each of which is interposed between two adjacent slats 3.
- both the driving chain links 7 and the connecting chain links 9 extend along less than the half of the total width W 1 of the roller shutter 1.
- both the driving chain links 7 and the connecting chain links 8 extend along less than a quarter of the total width W 1 , more preferably along less than an eighth and even more preferably along less than a tenth of the width W 1 ( Figure 2 ).
- the width W 2 of the connecting chain links 9 and the width W 3 of the driving chain links 7 are equal to or lower than 10 cm; more preferably, the widths W 2 and W 3 are equal to or lower than 5 cm, and even more preferably equal to or lower than 3 cm ( Figures 4 , 5 ).
- At least some driving chain links are arranged, link by link, for driving at least one slat 3 by compressing or decompressing each driving chain 5 longitudinally to itself (arrow F 1 ).
- this is achieved by ensuring that at least some driving chain links are arranged, link by link, for orienting such slat 3 perpendicularly or transversally to the imaginary surface, in which the sequence of slats 3 lays, opening the openings 11 ( Figures 1 , 3 ) when said chain 5 is more compressed longitudinally to itself, and so as to orient said slat 3 according to a direction substantially tangential or longitudinal to the imaginary surface wherein the sequence of slats 3 lays, closing the openings 11, when the chain 5 is less compressed longitudinally to itself ( Figure 2 ).
- the driving chain links 7 are arranged to drive, link by link, at least one slat 3 when the weight of the roller shutter 1 itself compresses the driving chain - or chains- 5 longitudinally to itself, by simplifying the mechanical construction and use of the roller shutter.
- a plurality of driving chain links 7 is singularly fastened to at least one slat 3 through a first 13 A and a second 13 B hinging pin that, by rotating together with the respective driving chain link 7, drive the respective slat 3.
- each driving chain link 7 is articulated with a first and adjacent connecting chain link 9 A through its first hinging pin 13 A and is articulated with a second and adjacent connecting chain link 9 B through its second hinging pin 13 B ( Figure 4 ).
- first and second hinging pins 13 A, 13 B are longitudinal to the slats 3.
- the roller shutter 1 may be provided with two groove guides 15, arranged along the sides thereof, and wherein or along which the chain links 7, 9 may slide ( Figure 1 ).
- the grooves 15 may be for example fastened integral to the opening of the window or door which is to be closed by the roller shutter 1.
- each first 13A and each second hinging pin 13 B preferably goes through a respective driving chain link 7, both are fastened to the same slat 3 for example by being screwed down into respective holes 34 A, 34 B ( Figure 5 ); moreover, the first pin 13 A and the second pin 13 B respectively go through a first 9 A and a second connecting chain link 9 B adjacent to each other and interposed between the slat 3 and the driving chain link 7.
- each slat 3 forms a first 30 and a second longitudinal edge 32, at least some slats 3 are fastened to the respective first 13 A and second 13 B pin, each slat in proximity of its first longitudinal edge 30, and the second longitudinal edge 32 of each slat 3 is arranged for resting onto an adjacent slat 3 when the opening 11 between the two slats 3 is closed ( Figure 2 ).
- the end edges 90 A, 90 B of at least some of the connecting chain links 9 rest on, optionally overlapping, the end edges 90 A, 90 B of the two adjacent connecting chain links 9 A, 9 B, so as to eliminate, or at least to reduce, air or light passing through the chain 5 ( Figures 2 , 4 ).
- each of them is advantageously provided with a relative longitudinal sealing gasket 36, arranged to rest on the lower edge 32 of an adjacent slat 3.
- the end edges 90 A, 90 B of at least some of the connecting chain links 9 preferably have crosswise acute angle sections, and/or such shapes to always have faces inclined relative to one another, so as to prevent the connecting 9 and driving chain links 7 from tripping and getting blocked into each other in positions longitudinal to the chain 5 itself and the slats 3 from getting stuck in a closing position.
- the roller shutter 1 is preferably arranged so that all the first 13 A and the second 13 B hinging pins 13 can never be aligned to each other.
- the reciprocal rotations of the chain links 7, 9 may be limited by appropriate mechanical butts, and/or the chain links 7, 9 may be more or less arched in shape, at least longitudinally to the driving chain 5. The operation of the roller shutter 1 will now be described.
- the roller shutter 1 is -partially or completely- lowered so that, thanks to its own weight, the various pins 13 A, 13 B are more misaligned with each other and the chain links 7 , 9 take more crosswise orientations with respect to the chains 5 and to the imaginary laying surface of the roller shutter 1.
- the driving chain links 7 in turn cause the respective slats 3 to rotate by orientating them perpendicularly, or in any case crosswise, to the imaginary laying surface of the roller shutter 1 and by opening the openings 11 ( Figures 1 , 3 , 5 ).
- the various slats 3 contact each other only to ensure a good seal against draughts and the passage of light, but not to drive their own opening and closing.
- roller shutter 1 clearly describes the construction simplicity of the roller shutter 1 and its great seal against the passing of air and light when it is closed. Since, when it is open, the only members extending across the window or door which it closes are the slats 3, there further emerges that the roller shutter 1 obstructs very little of the view and ventilation. Furthermore, the absence of further cross members -for example fixed cross members of the roller shutter of the document DE1237289 - contributes to simplifying the mechanical realization of the roller shutter 1 and to reducing its manufacturing costs.

EP189091
The author of the present invention has noted that these and other known roller shutters have a relatively complex, sometimes unreliable mechanical construction. The documentDE1237289 describes a roller shutter wherein, when lowered, its own weight causes the opening of a plurality of blades so as to allow the passage of air and light, while when lifted, again by gravity, the blades close, mostly preventing the light from the outside from passing, being, on the other hand, less effective in preventing the passage of air. Each blade is fastened to a cross member extending horizontally along the entire width of the window or other opening to close, and may slide inside a lateral guide to lift or lower the roller shutter. According to the author of the present invention, these cross members uselessly reduce the visibility through the lowered roller shutter, that is when the blades are open; furthermore, they uselessly increase the cost of the roller shutter and, on the other hand, do not contribute in a significant way to preventing draughts and the passage of air when the roller shutter is lowered and the blades are closed.
The documentFR2966862 - An object of the present invention is to overcome the drawbacks of the prior art mentioned hereinabove and, in particular, to provide a roller shutter having a relatively simple construction which, when working as a jalousie, provides a lower degree of obstruction to the view or the ventilation, and, when working as a roll-up shutter or blind, provides a greater degree of obstruction to air and/or light.
- Such object is achieved, according to the present invention, by a roller shutter having the features according to
claim 1.
Further features of the device are defined in the dependent claims.
The advantages attainable by the present invention will appear more clearly to the person skilled in the art from the following detailed description of a particular exemplary, non-limiting embodiment, illustrated with reference to the following schematic figures. -
-
Figure 1 shows a first perspective view of a portion of a roller shutter according to a particular embodiment of the invention and with part of the slats open; -
Figures 2 and3 respectively show a second and a third perspective view of the roller shutter ofFigure 1 , with the slats respectively closed and open; -
Figures 4 and5 respectively show a fourth and a fifth exploded perspective view of the roller shutter ofFigure 1 , with the slats respectively closed and partially open; - In the present description, the term "crosswise" means that two bodies have an inclination, one relative to the other, equal to or greater than 45°; the term "longitudinal" means that two bodies have an inclination, one relative to the other, lower than 45°; the term "chain link" corresponds to the italian term "maglia" or to the french term "maillon" for indicating particular elements of a chain.
Figures 1-5 relate to a roller shutter according to a particular embodiment of the invention, indicated with overallnumeral reference 1 and usable for example to reversibly close doors, windows or other apertures of buildings. Theroller shutter 1 comprises: - a plurality of
slats 3 arranged adjacent to one another and arranged for sheltering from wind, sun, light and bad weather; - at least one
driving chain 5 crosswise to which the plurality ofslats 3 is fastened and each of such chains extends according to the sliding direction of the roller shutter (Figures 1-3 ). Preferably, theslats 3 are substantially rigid so as to be substantially similar to small planks, and may consist of, or comprise, for example a section bar of plastic material, aluminium or other metallic material or wood. - The
driving chain 5 comprises a plurality ofdriving chain links 7 and a plurality of connectingchain links 9 articulated together - for example hinged - one after the other so as to form a succession and so that a plurality of
driving chain links 7 is articulated with, and interposed between, two connectingchain links 9, and a plurality of connectingchain links 9 is articulated with and interposed between twodriving chain links 7. Eachchain link chain links 9 may approximately have for example the shape of a rectangular plate (Figure 2 ). Preferably, thedriving chain links 7 are linked to the adjacent connectingchain links 9, 9A, 9B substantially like connecting rods. - According to one aspect of the invention, at least some of the
driving chain links 7 are fixed, link by link, to at least onerespective slat 3 and are arranged to drive it in order to reversibly open and close a plurality ofopenings 11, each of which is interposed between twoadjacent slats 3. - Moreover, both the
driving chain links 7 and the connectingchain links 9 extend along less than the half of the total width W1 of theroller shutter 1. Most preferably, both thedriving chain links 7 and the connecting chain links 8 extend along less than a quarter of the total width W1, more preferably along less than an eighth and even more preferably along less than a tenth of the width W1 (Figure 2 ). Preferably, the width W2 of theconnecting chain links 9 and the width W3 of thedriving chain links 7 are equal to or lower than 10 cm; more preferably, the widths W2 and W3 are equal to or lower than 5 cm, and even more preferably equal to or lower than 3 cm (Figures 4 ,5 ). Clearly, the lower the relative or absolute width W2, W3 of thechain links - Preferably at least some driving chain links are arranged, link by link, for driving at least one
slat 3 by compressing or decompressing eachdriving chain 5 longitudinally to itself (arrow F1). Preferably, this is achieved by ensuring that at least some driving chain links are arranged, link by link, for orientingsuch slat 3 perpendicularly or transversally to the imaginary surface, in which the sequence ofslats 3 lays, opening the openings 11 (Figures 1 ,3 ) when saidchain 5 is more compressed longitudinally to itself, and so as to orient saidslat 3 according to a direction substantially tangential or longitudinal to the imaginary surface wherein the sequence ofslats 3 lays, closing theopenings 11, when thechain 5 is less compressed longitudinally to itself (Figure 2 ). - Advantageously, the
driving chain links 7 are arranged to drive, link by link, at least oneslat 3 when the weight of theroller shutter 1 itself compresses the driving chain - or chains- 5 longitudinally to itself, by simplifying the mechanical construction and use of the roller shutter. Advantageously, a plurality ofdriving chain links 7 is singularly fastened to at least oneslat 3 through a first 13A and a second 13B hinging pin that, by rotating together with the respectivedriving chain link 7, drive therespective slat 3. Advantageously, eachdriving chain link 7 is articulated with a first and adjacent connecting chain link 9A through its first hingingpin 13A and is articulated with a second and adjacent connecting chain link 9B through its second hingingpin 13B (Figure 4 ). Preferably the first and second hingingpins slats 3.
Theroller shutter 1 may be provided with twogroove guides 15, arranged along the sides thereof, and wherein or along which the chain links 7, 9 may slide (Figure 1 ). Thegrooves 15 may be for example fastened integral to the opening of the window or door which is to be closed by theroller shutter 1. - In order to drive a
respective slat 3 and at the same time generate anarticulated chain 5, each first 13A and each second hingingpin 13B preferably goes through a respectivedriving chain link 7, both are fastened to thesame slat 3 for example by being screwed down intorespective holes Figure 5 ); moreover, thefirst pin 13A and thesecond pin 13B respectively go through a first 9A and a second connecting chain link 9B adjacent to each other and interposed between theslat 3 and thedriving chain link 7.
Preferably, eachslat 3 forms a first 30 and a secondlongitudinal edge 32, at least someslats 3 are fastened to the respective first 13A and second 13B pin, each slat in proximity of its firstlongitudinal edge 30, and the secondlongitudinal edge 32 of eachslat 3 is arranged for resting onto anadjacent slat 3 when theopening 11 between the twoslats 3 is closed (Figure 2 ). - Advantageously, at least when the driving chain - or chains- 5 are longitudinally compressed, and/or when the
slats 3 close theopenings 11, theend edges chain links 9 rest on, optionally overlapping, theend edges Figures 2 ,4 ). In order to increase the seal and reduce the air passing through the various closed slats, each of them is advantageously provided with a relativelongitudinal sealing gasket 36, arranged to rest on thelower edge 32 of anadjacent slat 3.
In order to drive theslats 3 thanks to the weight of theroller shutter 1 itself, theend edges chain links 9 preferably have crosswise acute angle sections, and/or such shapes to always have faces inclined relative to one another, so as to prevent the connecting 9 anddriving chain links 7 from tripping and getting blocked into each other in positions longitudinal to thechain 5 itself and theslats 3 from getting stuck in a closing position. - In order to further prevent the driving 7 and connecting
chain links 9 from tripping and the occurrence of a dead centre between them, theroller shutter 1 is preferably arranged so that all the first 13A and the second13 B hinging pins 13 can never be aligned to each other. To that purpose, the reciprocal rotations of thechain links chain links driving chain 5.
The operation of theroller shutter 1 will now be described. - In the condition of
Figure 2 the slats and thechain links roller shutter 1 are hung to one another and as aligned as possible to one another by gravity; again by gravity theslats 3 close theopenings 11, theupper edges 30 of eachslat 3 rest on and partially overlap thelower edges 32 of anadjacent slat 3; similarly, theupper edges 90A of each connectingchain link 9 rest on and partially overlap thelower edges 90B of an adjacentconnecting chain link 9, eliminating or at least minimising the air or light passing through the roller shutter; the latter inFigure 2 works substantially as a conventional roll-up shutter or roll-up gate. On the contrary, in order to work as a jalousie, theroller shutter 1 is -partially or completely- lowered so that, thanks to its own weight, thevarious pins chain links chains 5 and to the imaginary laying surface of theroller shutter 1. By rotating, thedriving chain links 7 in turn cause therespective slats 3 to rotate by orientating them perpendicularly, or in any case crosswise, to the imaginary laying surface of theroller shutter 1 and by opening the openings 11 (Figures 1 ,3 ,5 ). Thevarious slats 3 contact each other only to ensure a good seal against draughts and the passage of light, but not to drive their own opening and closing. - The foregoing description clearly describes the construction simplicity of the
roller shutter 1 and its great seal against the passing of air and light when it is closed. Since, when it is open, the only members extending across the window or door which it closes are theslats 3, there further emerges that theroller shutter 1 obstructs very little of the view and ventilation. Furthermore, the absence of further cross members -for example fixed cross members of the roller shutter of the documentDE1237289 - contributes to simplifying the mechanical realization of theroller shutter 1 and to reducing its manufacturing costs.
