Definitions
- the present invention relates to a closure or sun protection system.
- the invention also relates to a method of implementing a closure or sun protection system.
- the field of the invention is that of roller shutter type installations, designed to equip a building opening such as a door or a window arranged in a wall or a roof.
- a shutter comprises an apron wrapped around a tree and which takes place between two scenes to hide the window.
- a manual or electric action makes it possible to maneuver the rolling shutter downhill or uphill.
- a specific mechanism is generally provided for inclining the blades relative to the plane of the deck.
- EP-A-0 141 805 discloses a roller shutter with steerable blades, comprising a chain movable in translation in a slide. Each blade constituting the shutter apron is secured to a rod which cooperates with the chain through complementary threaded profiles.
- a rail cooperating with the chain can be moved in translation by an auxiliary actuator, in a direction parallel to the deck and perpendicular to the direction of rise and fall of the chain.
- the movement of the rail causes a movement of the chain and therefore a rotation of each rod due to the cooperation of complementary threaded profiles.
- the movement of the rail causes the inclination of the shutter blades secured to the rods.
- the mechanical forces transmitted between the different parts can cause rapid wear of these parts.
- such a shutter requires a first actuator to move the deck and a second actuator to move the rail in the slide, which is expensive and bulky.
- DE-B-1 237 289 discloses a rolling shutter with steerable blades, comprising an apron provided with several shutter blades mounted on transverse bars. Slides are arranged on each side of the deck. An intermediate element is interposed between each bar, behind the scenes. The shutter does not therefore include a lifting chain dissociated apron. In practice, the bars and the intermediate elements tilt when they come to bottom stop behind the scenes, because of gravity. Thus, the low abutment brings about the inclination of the shutter blades integral with the transverse bars.
- the purpose of the present invention is to provide an improved roller shutter, in particular to guide the blades while being simple, economical and compact.
- the subject of the invention is a closure or sun protection system, in particular of the shutter type, comprising:
- an apron comprising a plurality of shutter blades, each shutter blade being pivotable about a pivot axis defined by at least one lateral shaft extending laterally from a first edge of the shutter blade;
- each chain disposed laterally on either side of the deck and movable in translation along a deployment axis perpendicular to the pivot axis, each chain supporting a lateral shaft of each shutter blade, and
- a cam mounted pivotably on a lateral shaft of each active blade and cooperating, on the one hand, with the activation strip and, on the other hand, with a portion integral in rotation with the active blade, so as to cause the rotation of this active blade during specific movements of the chain.
- the invention allows to tilt the blades in a simple manner, regardless of the position of the deck.
- the installation of roller shutter according to the invention does not require additional actuator, in addition to the motor used to raise and lower the deck.
- the tilting means are arranged in the slide of the installation, which protects them from the weather and thus slows down their aging, while providing a great discretion and a neat aesthetic to the shutter. Since the operation of the tilting means does not depend on the relative positioning between the blades and a mechanism internal to the slide, the length of the slides can therefore be freely modified during assembly. No auxiliary mechanism is grafted on the blades, or on the slides that are monobloc. Installation of the installation is carried out as on a standard rolling shutter with non-steerable blades, without requiring complex adjustment operation, and the exposure time is reduced. According to other advantageous features of the invention, taken separately or in combination:

- the chain comprises rollers capable of rolling on a bearing surface arranged in an interior space of a guide guide of the chain, the bearing surface being situated opposite a surface of the strip; activation cooperating with each cam;
- Each roller is movable in translation along the axis of deployment in an oblong slot of a chain link
- each roller is of deformable material, capable of crashing against the bearing surface when each cam cooperates with the activation strip;
- the activation strip is made of deformable flexible material, in particular an elastomer such as silicone foam;
- the activation strip is reported in a slide disposed on one side of the deck;
- each shutter blade comprises a groove which extends parallel to the pivot axis and is configured to cooperate with the first edge of an adjacent shutter blade
- the two lateral shafts pass through the first edge of each shutter blade and form a one-piece through rod;
- the tilting means are configured to tilt each active blade during a translation of the chains along the axis of deployment in a rising direction of the apron, whatever the position of the deck, provided that at least one blade is arranged in an active area of the installation defined between two slides;
- the tilting means are configured, on the one hand, to separate the first edge of each active blade and the second edge of an adjacent active blade during the movement of the chain in a rising direction of the apron and, on the other hand, to fit the first edge of each active blade and the second edge of an adjacent active blade during the movement of the chain in a downward direction of the apron;
- the installation comprises a single actuator configured to move the chain and the blades in translation selectively in a first downward direction of the apron or in a second upward direction of the apron and to move each active blade from its rest position to its position inclined.
- the installation comprises on each of its left and right sides, in symmetry with respect to a median plane parallel to the first axis and perpendicular to the second axis, a chain movable in translation parallel to the first axis, an end of a shaft associated with each shutter blade and extending along the second axis, and a guide slide of the chain which extends along the first axis and in which are arranged the inclination means associated with one or more active blades, especially when the or the active blades are in an inclined position.

- the installation 10 also comprises means for inclining the blades 20, which are arranged on each left 13 and right side 14 of the apron 18.
- These inclination means include, for each blade 20, a lateral shaft 60 with one end 62 provided with a stop 68, a cam 70 mounted on the end 62 and having a finger 78, and a spring 90 mounted on the end 62 between the stop 68 and the finger 78.
- each cam 70 is equipped with its finger 78 driving the abutment 68 and the shaft 60 during a particular movement of the cam 70, as described below.

Also, the box houses a drive motor of this tube, this motor being Diagrammatically represented by an actuator block A10 in dotted lines in FIGS. 1, 2, 1 1 and 12. Alternatively, this actuator may be a part of a conventional manual control system adapted for raising and lowering the apron 18.

- the apron 18, of a on the other hand is translated into a plane P18 which extends between the slides 30.
- the slide 30 extends along the X axis, from an upper end 35 to a lower end 36. As shown in particular in Figure 4, the slide 30 has a hollow profile which defines an interior space 32. In this 32, the slide 30 comprises a flat surface 34 and a housing 38 for receiving an activation strip or friction adhesive strip 80.

- this active area 17 stops a few centimeters below the upper end of the backstage 35 30, to allow the blades 20 to return to the plane P18 before entering the winding box during the ascent of the deck 18.
- This area 17 is identified by a dashed border in Figure 2.
- the blades 20 movable in translation parallel to the plane P18 can be actuated by the tilting means and are then designated as active blades 21, potentially inclinable, or inclined blades 22.
- a blade active 21 is considered as such when the associated shaft 60 and cam 70 enter the active zone 17, as shown in FIGS. 5 and 6.
- blades 20 are slightly curved on the inner side 1 1, between the edges 20a and 20b. Also the blades 20 are provided with overlapping bibs 29 on their lower edges 20b. These flaps 29 participate in the concealment of the opening on which the installation 10 is mounted, both in the rest position and in the inclined position of the blades 20.
- link 42 of the chain 40 has a profile "H" curved on the inner side 1 1, with a central portion 43 which forms the central portion of the H, an upper end 45 provided with upper ears 451 and 452, and a lower end 46 provided with lower lugs 461 and 462.
- the lugs 451, 452, 461 and 462 protrude from the middle portion 43 on their respective sides, and are configured to cooperate with the corresponding lugs. a neighbor link 42.
- Each ear 451 to 462 has a cylindrical orifice 47 passing through, so that four corresponding orifices 47 extend coaxially along an axis Y47 parallel to the axis Y of the shafts 60.
- a central housing 454 In the median portion 43 is defined a through hole 44, closer to the upper end 45 than the lower end 46, which extends along the Y axis and is shown in dashed lines in Figure 4.
- each link 42 of the chain 40 is provided with a roller 50 which rolls on the surface 34 inside the slide 30.
- Each roller 50 has a central portion 54 and side portions 56. These parts 54 and 56 are cylindrical, the diameter of the portion 54 being greater than the diameter of the portions 56.
- the portion 54 is projected out of the housing 454 and bears on the surface 34, while the parts 56 are pivotally mounted in the orifices 47 formed in this effect in the links 42.
- the parts 56 of the rollers 50 constitute axes of articulation of two adjacent links 42 joined at their ears 451, 452, 461 and 462.
- Each link 42 is traversed by one of the cylindrical shafts 60, which is pivotally mounted along the axis Y in the orifice 44.
- the shaft 60 and the associated blade 20 are integral with the chain 40 in translation along the axis X, while being able to pivot about the Y axis.
- the end 62 of the shaft 60 is disposed in the interior space 32 of the slide 30, opposite the blade 20 and closer to the side. outside right 14 as the chain 40, as shown in particular to Figures 3 and 4.
- the stop 68 arranged at the end 62 is substantially cylindrical in shape and extends from the end 62 along a radial axis A68 relative to In practice, this axis A68 is movable in a plane parallel to the plane Pm during the rotation of the shaft 60.
- a cam 70 is mounted at each end 62 of each shaft 60, between the chain 42 and the stop 68, so that the cam 70 is integral in translation with the associated shaft 60.
- the cam 70 has an inner flat face 71, an outer flat face 72, an internal orifice 73 shown in dotted line in FIG. 4 which passes through the cam 70 between the faces 71 and 72, and a profiled outer surface 74.
- the faces 71 and 72 are parallel to each other and perpendicular to the Y axis.
- the shaft 60 passes through the orifice 73 along the Y axis, so that the cam 70 can pivot around the shaft 60, in a first direction of rotation R1 or in a second direction of rotation R2, as shown in FIGS. 5 to 7 and 9.
- the profiled surface 74 is intended to cooperate with a friction surface 81 of the activation strip 80, with a variable friction contact depending on the orientation of the cam 70 by rotation about the Y axis.
- the profiled surface 74 comprises different friction zones 75, 76 and 77 intended to interact with the activation band 80, the particularities of which will be detailed below in connection with the successive operating phases.
- This ring 99 allows in particular to position the cam 70 on the shaft 60 along the axis Y.
- the surface 74 is positioned accurately relative to the band 80 and, on the other hand, the finger 78 is accurately positioned relative to the stop 68.
- a spiral return spring 90 or torsion spring, is fixed to the end 62 of the shaft 60, between the stop 68 and the face 72 of the cam 70.
- the spring 90 In the extension of its winding around the end 62, the spring 90 has an elongate portion 91 which cooperates with the finger 78.
- the spring 90 thus exerts on the cam 70 and through the finger 78, an elastic torque which tends to rotate the cam about the Y axis clockwise in FIG. 5.
- the spring 90 also has the function of damping the vibrations between the shafts 60 and the cams 70 associated with the blades 20.
- the finger 78 is substantially cylindrical in shape and protrudes perpendicularly to the surface 72, along an axis Y78 parallel to the Y axis and rotatable about this axis Y.
- the finger 78 is therefore suitable, on the one hand, when the cam 70 pivots in the direction of rotation R1, pressing on the part 91 which then flexes in a plane perpendicular to the axis Y78, and, on the other hand, pressing against the stop 68 when the cam 70 rotates in the direction of rotation R2.
- the activation strip 80 is composed of a deformable material, such as silicone foam, or any type of elastomer suitable for the present application.
- the cams 70 frictionally cooperate with this band 80, at its surface 81 which is deformable, differentially as the deck 18 moves in the direction D1 or in the direction D2.
- the coefficient of friction between the cam 70 and the band 80 varies as a function of the friction zone 75, 76 or 77 of the cam 70 which is in contact with the surface 81.
- the profiled surface 74 is such that a radius r75 defined parallel to the median plane Pm between the Y axis and the zone 75 is less than a radius r76 defined between the axis Y and zone 76.
- the cam 70 is at rest when it is located outside the slide 30, that is to say outside the active zone 17.
- the rollers 50 roll on the surface 34 and the cams 70 come into contact with the band 80.
- the rollers 50 block the transverse displacement of the links 42, the shafts 60 and the blades 20, that is to say their displacement perpendicular to the translation plane P18 of the apron 18. Consequently, the cam 70 abuts against the activation strip 80 at the zone 75 and is disengaged by pivoting in the direction R1 , that is to say, approaching the outer side 12.
- the cam 70 slides on the strip 80 in the direction D1, while being subjected to the action of the spring 90.
- the force F80 is low compared to the thrust exerted on the chain 40 by the actuator A10 during the descent of the deck 18, as well as the own weight of the deck 18 and the chain 40, the friction of the zone 75 on the surface 81 does not hinder the descent of the deck 18 in the direction D1.
- a first pulse of the actuator A10 generates a pulling force of the chain 40 upwards, which tends to raise the next deck 18 the direction D2.
- Each link 42 is driven by an X axis translation movement in the direction D2 and drives the next link 42 of the chain 40, below, while the rollers 50 located in the slide 30 roll on the surface 34 .
- the spring 90 then exerts a return torque on the cam 70 which is blocked transversely by the roller 50, so that this cam 70 adheres and sinks progressively into the deformable strip 80 by pivoting in the direction R2. More specifically, the friction zone 76 comes into contact with the surface 81 instead of of the zone 75, and sinks into the band 80 as shown in FIGS. 7 and 8.
- This zone 76 is configured to present a coefficient of friction, with the surface 81 of the activation band 80, which is greater than the coefficient
- the surface 74 is such that the radius r76 is greater than the radius r75 and / or the surface roughness of the zone 76 is greater than the surface roughness of the zone 75.
- the band 80 is deformed by crashing under the pressure of the zone 76, thus creating an obstacle to the raising of the cam 70 in the direction D2, which prevents this cam 70 from sliding on the surface 81 and forces it to rotate around the Y axis in the R2 direction.
- the vertical translation movement of the chain 40 is coupled to three phenomena: the locking in transverse translation of the chain 40 and the cams 70 by the rollers 50, the torque exerted by the return spring 90 on the cams 70 , and the relatively high coefficient of friction between the zone 76 of the cam 70 and the band 80.
- each inclined plate 22 is stabilized with an angle ⁇ relative to the plane P18 of the deck 18, resulting from the particular configuration of the profiled outer surface 74 of the cams 70.
- this angle ⁇ defined between the A68 axis and the plane P18 is equal to approximately 45 °, and is preferably between 30 ° and 60 °, depending on the geometry of each cam 70.
- the edge 20b of each blade 22 deviates from the plane P18 and the edge 20a of the next blade 22 of the apron 18. At this stage, if the actuator A10 continues to raise the deck 18 in the direction D2, the zone 77 of the cam 70 slides on the activation strip 80.
- this zone 77 has a low coefficient of friction in comparison of the zone 76 which was forced to penetrate into the strip 80 prior to the orientation of the inclined blades 22.
- the transverse spacing, perpendicular to the plane P18, between the zone 77 and the surface 34 is reduced.
- the planar zone 77 has a large bearing surface and does not penetrate the band 80.

With the actuator A10, the apron 218 and the chains 240 wind up and unroll around the winding tube T210. At the same time, the chains 240 slide behind the scenes 230.
- the apron 218 is attached to the winding tube T210 by two support blades LS1 and LS2 located on the upper side 15 and articulated to each other parallel to the Y axis. More specifically, preferably, the first blade LS1 support is attached to the winding tube T210 of the upper side 15 with the help of automatic locks V210, while the chains 240 are supported by the second support blade LS2 via support rods BS2 located on both sides Another of the apron 218.
- a blade 218A constitutes the first blade of the deck 218 and the highest active blade 221 pivotable from a rest position to an inclined position.
- the apron 218 is also attached to a load bar 219 located on the lower side 16.
- the chains 240 connect the blades 220 to each other, from the load bar 219 to the second support blade LS2, cooperating with the shafts 260, and thus make it possible to guide the deck 218 in translation between the runners 230.
- the apron 218, on the one hand wraps and unrolls around the winding tube T210 and, on the other hand, translates into the plane P18 which extends between the slides 30 .
- each lock V210 is composed of a link connected to the tube T210, of a link connected to the first support blade LS1, as well as one or more intermediate links depending on the winding diameter of the deck 218 and the dimensions of the box C210.
- each lock V210 unrolls the tube T210 and is arched creating a rigid connection between the tube T210 and LS1 support blade.
- the links of the locks V210 abut against each other, being substantially aligned, so as to form a rigid non-deformable assembly.
- the locks V210 are described in particular in document FR-A-2 775 314.
- each connecting rod BS2 connecting one of the chains 240 to the blade LS2 creates an articulation between the chain 240 and the blade LS2, thus allowing, on the one hand, the winding of the apron 218 on the tube T210 and, on the other hand, the carrying the weight of the chains 240 on the support blade LS2 and not on the shaft 260 of the first blade 218A of the deck 218.

- the spring 290 In the extension of its winding around the end 262 of the shaft 260, the spring 290 has a portion 292 wound around the abutment 268.
- the positioning and operation of the tilting means of the blades 221 in the slide 230 is comparable to the second embodiment, except that the cam 270 is not provided with a drive finger comparable to the finger 78.
- each cam 270 has a recess 277, connecting the outside and the inside of the cam 270.
- Each cam 270 has an inner surface 278 formed between the recess 277 and the outside of the cam 270. This surface 278 is substantially flat, perpendicular to the axis Y and the axis A68 of the stop 268 regardless of the position of the cam 270, and performs the same function as the finger 78 of the first mode of embodiment, cooperating with the abutment 268 secured to the shaft 260.
- the manufacture of the cam 270 is simplified.
- Each cam 270 also includes tabs 279, for securing the cam 270 to the shaft 260 by pinching, which facilitates mounting.
- the shaft 260 pivots in the directions R1 or R2 being supported by two orifices 244 of the link 242, on either side of the cam 270, which limits the overhang on the end 262 when the cam 270 slides frictionally on the strip 80.
- a washer 264 is fixed to the end 262 of each shaft 260 to prevent accidental sliding of the links 242 along the Y axis. With this washer 264, the link 242 is positioned axially. on the axis 260, which keeps an optimum operating clearance between the cam 270 and the stop 268 located in the recess 277 of the cam 270.
- the transverse guidance of the apron 218 inside the slide 230 is ensured by the links 242 and the rollers 250.
- the installation 210 further comprises a function of locking the active blades 221 one in the other in the rest position.
- each link 242 has for this purpose a vertical oblong slot 247 at its lower end 246.
- the light 247 is traversed by the axis and the side portions 256 of one of the rollers 250.
- This roller 250 is thus movable in translation in the light 247 of the link 242 and integral in translation of the lower link.
- links 242 can translate with respect to others along the axis X.
- the blades 221 are translatable relative to each other along this axis X.
- the blades 221 When the deck 218 is in the lowered configuration, that is to say closed, the blades 221 are fitted into each other.
- the links 242 of chains 240 are all retracted into each other but are not in vertical abutment with each other.
- the vertical stop is made between the edges 220a and 220b of the blades 221.
- the lower edges 220b of the active blades 221 comprise a transverse groove 228 and a projecting portion 229 which extend along the blade 221 along the X axis.
- the upper edge 220a has a rounded shape configured to fit into the groove 228, which forms a rounded hollow complementary to the edge 220a.
- the blades 221 When the deck 218 rises in the direction D2, the blades 221 are separated from each other at their edges 220a and 220b and can then tilt in an inclined position.
- the separation of the blades 221 and their inclination start from the top of the deck and progress downwards, while the links 242 bear against the lower end portion of the oblong slots 247.
- the step links 242 go from 43 millimeters to 50 millimeters approximately.
- the blades 221 deviate from each other in the X-axis direction, and then gradually incline one after the other as the rise, as shown in particular in FIGS. 18.
- the sets of lights 247 of each link 242 catch up one after the other, thus creating a progressive inclination of the active blades 221.
- the stroke of the links 242 required for the disengagement of the edges 220a and 220b of the blades 221 corresponds to the distance over which the cams 270 will rotate freely without driving the blades 221 in rotation.
- the spring 290 expands by 23 ° before the abutment 268 integral with the shaft 260 of the blade 221 does not bear against the drive face 278 of the cam 270 to orient the blade 221.
- the installation 10, 1 10 or 210 requires no auxiliary power source, in addition to the actuator A10, to guide the shutter blades 21 or 221.
- the description below is made with reference to the installation 10, it being understood that the explanations are valid for the installations 1 10 and 210.
- the cams 70 present in the active zone 17 of the slide 30 drive the active blades 21 in rotation.
- No obstacle connection is used to orient the blades 21, that is to say that there is no mechanism permanently present in the slide 30 to actuate the cams 70 and the shafts 60, with the exception of the activation band 80.
- the length of the slides 30 can therefore be modified at will, in particular to adjust the height of the active zone 17 where the blades 20 are tilted during a movement of the apron 18.
- the installation 10 does not require to hang a specific mechanism on the upper blade in order to exert a tensile force on the blade, according to a maneuver that can be carried out only when the deck is lowered to the maximum.
- the installation 10 is designed to minimize the size of the parts that make the junction between the inside of the slide 30 and the outside environment. This function is provided solely by the shafts 60, without any control rod protruding from the box or slides.
- the upward movement of the deck 18 by the actuator A10, coupled with the adhesion of the cams 70 against the strip 80 disposed inside each slide 30, is sufficient to orient the blades 21.
- the inclination means are configured to incline each active blade 21 during a translation of the chain 40 along the first axis X, in the upward direction of the apron 18.
