Definitions

  • the present invention regards a mechanism useful for orienting a sunbreaker slat, through rotation along its longitudinal median axis, with the feature of being modular and thus composable according to a number of desired slats, and also articulated one relative to another so as to allow a curtain of slats to be wound on a collection roller, such curtain resulting from the connection of the first module and the further modules.
  • jalousie curtains with the slats orientable through mechanisms are already known, but these systems provide for the planarity of the curtain as well as the provision of the framework through perimeter structures containing them.
  • windable jalousies with orientable slats are described in WO2013/164434A1 , DE1237289B and EP189091A2 .
  • Windable curtains are also known formed by split sunbreaker slats that, or however by sunbreaker slats made up of several elements. Depending on the position of the curtain, part of such elements can be oriented like if they were flaps by partially rotating them along the mounting axis, which is consequently the end axis. The slats are oriented together with the next slats.
  • such solutions are quite far from working like a typical jalousie due both to the limited orientation obtained, which limits the functionality and utility of such products, and to the aesthetic appearance of the slats thus oriented which is also far from the typical look of a traditional jalousie with orientable slats.
  • An object of the present invention is to overcome one or more of the said drawbacks of the prior art.
  • the single module can be composed according to the required length and the desired number of slats simply by fitting a pin (29) through the holes (9-9') present in the support (7) and the holes (14-14) present in the lid (13) making the coupling stable and integral but simultaneously articulable along the longitudinal axis of the pin itself and in addition such connection places the rods (19) in contact in an articulable fashion through the ovoidal ring (21) abutting with the lower end of the solid body (20) of the subsequent rod (19).
  • the orientation of the slats (30) making up the curtain occurs with an upward thrust, for its stroke value, of the rod (19) inserted in the first module (33') at the bottom part of the curtain.
  • Such rod being in contact with the subsequent rods above it, pushes in the same direction and the same stroke synchronously and simultaneously all the remaining rods up to the last of the last module upwards (33) thus determining the simultaneous rotation of the caps (23) and thus of the slats (30) just like it occurs in a classic jalousie.
  • the modular mechanism according to claim 12 or 13 may comprise at least one first and one second module assembled together by fitting the pin (29) of the first module:
  • the modular mechanism according to claim 1 does not comprise the features according to claim 12 and/or 13.
  • the modular mechanism according to claim 1 comprises the features according to claim 12 and/or 13.
  • such object is achieved through a method for making modular jalousies having orientable sunbreaker slats constituting a curtain windable on a roller, characterised in that the method for making a single module comprises the following operations:
  • the single module can be composed according to the necessary length and the desired number of slats by simply fitting a pin (29) through the holes (9-9') present in the support (7) and the holes (14-14) present in the lid (13) making the coupling stable and integral but simultaneously articulable along the longitudinal axis of the pin itself and in addition such connection places the rods (19) in contact in an articulable fashion through the ovoidal ring (21) abutting against the lower end of the solid body (20) of the subsequent rod (19).
  • such object is achieved through a method for making jalousies having orientable sunbreaker slats constituting a curtain windable on a roller, characterised in that the method for the formation of a curtain jalousie comprises the following steps:
  • the orientation of the slats (30) forming the curtain occurs through an upward thrust, for a stroke value thereof, of the rod (19) inserted in the first module (33') at the bottom of the curtain, and such rod, being at contact with the subsequent ones above it, provides for pushing in the same direction and for the same stroke synchronously and simultaneously all the remaining ones up to the last of the last module at the top part (33) determining the simultaneous rotation of the caps (23) and thus of the slats (30) just like it occurs in a classic jalousie.
  • the chain connection articulable between the modules (33) obtained through the pin (29) allows the winding thereof on a roller.
  • Another aspect of the invention relates to the method for making a single module of the mechanism characterised in that it traverses the median hole of the lid with the cylindrical body of the cap, fitting the fork of the rod in the eccentric bridge of such body and positioning the entirety on the support where the rod will find the sliding track for a to and fro movement.
  • Such movement which will act, through the fork of the rod, on the eccentric bridge of the cylindrical body of the cap will determine the rotation of the latter along the axis of the said cylindrical body.
  • Figures 1-6 regard a modular mechanism and a sunbreaker curtain or jalousie according to a first embodiment of the invention.
  • Such modular mechanism preferably in turn comprises:
  • the support element 7 may comprise an elongated solid element provided for example with one or more of the following elements:
  • the lid element (13) is suitable to be coupled for example fittingly with the support element (7), and comprises for example a solid body with a for example rounded, elliptic or more generally curved base, substantially equal to that of the support (7).
  • the lid element 13 is preferably provided, at the ends thereof, of one or more of the following elements: two through holes (14-14') located along the longitudinal axis of the lid element 13 and concentric, or coaxial, with those of the support (9-9');
  • the rod element (19) also referred to as “driving tension rod 19" in the present description, comprises preferably an elongated solid body (20) having - at an end - a preferably ovoidal ring (21) and - in the middle - a fork (22) with the opening facing in the orthogonal direction with respect to the body (20) of the rod itself;
  • the cap element (23) comprises preferably a shaped plate (24) provided on a face of a mushroom-like element -or another relief - for relief fitting (25).
  • a cylindrical body (26) On the opposite face, and preferably in median position, on the cap element 23 there is obtained a cylindrical body (26), concentric or coaxial to the hole (15) of the lid (13) and to the seat (10) of the support (7), and such body 26 is provided of a groove (27) in undercut where there is positioned a bridge (28) having the longitudinal axis in a position eccentric to that of the cylindrical body (26) and dimensioned so as to be inserted in the fork (22) of the rod (19);
  • the pin element (29) is dimensioned to be engaged in the end holes (9-9') of the support (7) as well as in the holes (14-14') of the lid (13) and lastly suitable to traverse the ovoidal ring(21) of the rod (19) ;
  • the sunbreaker slat element (30) preferably comprises a tubular element (31), with shape suitable to receive the mushroom-like element (25) of the cap (23) and preferably provided of a shaped crosspiece (32) having the functions of reinforcement and being a seat for a possible fixing and safety screw (not shown).
  • the mounting of the module (33) shown in figure 2 with the cap (23) in a closure position at 0°, and in figure 3 with the cap (23) in an opening position at 90° preferably occurs according to the following method:
  • Such projection represents the stroke of the rod (19) along the track (11) useful to act on the bridge (28), of the cap (23), which being offset with respect to the rotation axis of the cap itself determines the rotation thereof according to the mechanical effect of the ashimbly crank-connecting rod.
  • the method for making a curtain jalousie windable obtained through the use of the module mechanism subject of the present invention, may occur according to the description below with reference to figure 4 .
  • module chain rows (33) connecting each of them with the subsequent one by inserting and fitting the pin (29) through the end holes (9-9') present in the support (7) and the holes (14-14') present in the lid (13).
  • connection between the modules shall be integral with but articulable along the longitudinal axis of the pin (29) and simultaneously will place each ovoidal ring (21) in contact with the lower end of the solid body (20) of the rod (19).
  • a screw (not shown) may for example be used ensuring such coupling.
  • Figure 5 shows a curtain or a previously assembled curtain with the sunbreaker slats in a closure position and thus with rotation equal to 0°
  • figure 6 shows the same curtain or curtain but with the sunbreaker slats in an opening position and thus with rotation equal to 90°.
  • such projection represents the stroke made by the rod (19) to allow the rotation action of the cap (23), and thus of the slat (30), by engaging the fork (22) on the bridge offset (28).
  • first rod 19 pushes the lower end of a second rod 19 which is located immediately above the first rod 19 upwards.
  • Such thrust action may be obtained in various ways. For example it can be obtained by extending the body of the rods 19' of the module at the bottom part which- touching the floor before the curtain itself - would act as thrust pistons due to the weight of the curtain itself.
  • an electrically controlled mechanical device could be considered but in any case for such actuation examples and further possible examples the object of the invention is fundamental, consisting in the assemblable mechanism module in an articulated fashion to allow the formation of a curtain jalousie windable on a roller like a normal windable curtain.
  • a modular mechanism according to the invention for providing jalousies having orientable sunbreaker slats forming a curtain for example windable on a roller may generally comprise:
  • the driving chain link (35) preferably comprises the lid 13 and the cap 23; advantageously it further comprises within itself an driving tension rod (19) arranged for driving the sunbreaker slat (30) by causing it to rotate on itself longitudinally to itself.
  • the sunbreaker slat (30) is fixed to the driving chain link (35) at an end of the sunbreaker slat (30) itself.
  • the aforementioned modular mechanism comprises an eccentric mechanism through which the driving tension rod (19) actuates the sunbreaker slat (30).
  • the eccentric mechanism may comprise an actuation shaft (37) arranged longitudinally to the sunbreaker slat (30).
  • the actuation shaft (37) comprises a first section (26), and a second section (28) longitudinal but offset with respect to the first section (26).
  • the axis of the actuation shaft 37 preferably passes through the middle of the transverse sections of the relative sunbreaker slat 30.
  • the driving tension rod (19) is engaged, for example through a fork seat 22 or other seat or recess, with the second section (28) of the actuation shaft (37) forming a sort of crank mechanism which drives the shaft (37) causing the latter to rotate on itself.
  • a sunbreaker jalousie according to the invention may comprise several modular mechanisms of the type previously described.
  • sunbreaker jalousie may comprise several modular mechanisms of the type previously described.
  • the at least one first driving tension rod (19) of the first driving chain link (35) may be actuated by a second driving tension rod (19) belonging to the second driving chain link (35) adjacent to the first driving chain link (35).
  • the second driving tension rod (19) belonging to the second driving chain link (35) may actuate the first driving tension rod (19) pushing or pulling it.
  • the driving tension rod s (19) of the plurality of driving chain links (35) may be arranged in a row one after the other and each substantially longitudinal to the driving tension rod or rods (19) adjacent thereto.
  • a plurality of driving chain links (35) may each comprise a hinging pin (29) through which a first driving chain link (35) is hinged to an adjacent second driving chain link (35) so as to form the driving chain; in addition a plurality of driving tension rod s (19) may each form an oblong slot (21) in which there is inserted a hinging pin (29). Preferably such oblong slot is arranged at an end of the relative driving tension rod 19.
  • each driving chain link 35 is smaller than the length of the sunbreaker slats 30, where such width and such length are measured according to a direction perpendicular to the direction for unwinding and winding the jalousie itself. More preferably the width of each driving chain link 35 is equal or smaller than a fifth of the length of the sunbreaker slats 30, even more preferably equal to or smaller than one tenth or one twentieth of the length of the sunbreaker slats 30, so as to allow a greater passage of light when the slats 30 are open.
  • Figures 7-11 regard a modular mechanism and a curtain or sunbreaker jalousie according to a second embodiment of the invention.
  • each rod element 19' or of each driving tension rod 19', has an upper edge 210 forming a sort of guide or track, while the lower end 212 of each driving tension rod 19 advantageously forms a concave seat arranged for being coupled to the track edge of the upper edge of an adjacent tension rod 19', so as to be able to slide along it without slipping off in the direction perpendicular to the edge itself ( Figures 7-9 ).
  • the rods 19' are coupled one to another substantially forming an internal chain and considerably improving the synchronous aspect of the opening and closure of the slats 30 and generally the operating fluidity of the mechanism.
  • the upper edge 210 may have substantially T-shaped transverse sections, while the lower end 212 may have substantially C-shaped transverse sections.
  • the upper edge 210 which forms a sort of guide or track also extends around the upper curved portion of the slots 21', so as to allow two adjacent tension rods 19' to rotate with respect to each other. This allows maintaining the rods 19' coupled to each other even when the curtain of the jalousie is rolled, thus improving reliability thereof.
  • the two teeth forming the fork 22' advantageously have the ends folded in the direction longitudinal to the body of the rod 19', thus facilitating the sliding in the relative driving chain link 35 thus maintaining it more firmly in one position and reducing the risk of the eccentric pin 28' projecting from the fork 22'.
