Description

The present invention relates to a sliding hinged shutter.

  sliding shutter. The sliding shutters comprise, in a known manner, several blades extending in a longitudinal direction and hinges integrating

  two by two the blades along their longitudinal edge.

  The blades are articulated in these hinges between a deployed position, in which the blades are located in the same plane also containing the hinge, and a folded position, in which the blades are located in two planes parallel and perpendicular to the hinge. Each blade swivels

  thus an angle of 90 around the hinge.

  Each hinge is in the form of a profile, the edges of which have a curved end, the central axis of which corresponds to the axis of

  pivoting of each blade in the hinge.

  Each blade has a connecting element also curved and adapted to pivot around

  the curved end of a bank of a hinge.

  The edges of each hinge and the connecting elements of the blades have a cross section of shape

  circular or possibly spiral.

  These known sliding shutters have the disadvantage of having hinges allowing rotation of an angle greater than 90 of each blade around the hinge, which can cause folding

  in the opposite direction of the blade relative to the hinge.

  In addition, a large clearance generally exists at the connection of each blade with the hinge, hindering the pivoting guide of the blade.

around the hinge.

  The object of the present invention is to solve the aforementioned drawbacks and to propose a sliding louver whose hinges, while blocking the pivoting of the blades beyond the extreme positions of their movement, have surfaces making it possible to obtain both guidance in pivoting of the blades and a continuity of the apparent surfaces when the

  louver is unfolded, making cleaning easier.

  The sliding shutter covered by the invention comprises blades extending in a longitudinal direction and at least one hinge adapted to secure two adjacent blades, said hinge being made up of a profile extending parallel to

said longitudinal direction.

  According to the invention, the hinge comprises, in a transverse plane of said profile, a central core, two edges substantially in the shape of an arc of a circle and two wings with curved end fixed respectively to said edges and extending substantially parallel to the 'central core of said profile, and said blades comprise on longitudinal edges a connecting element comprising a curved end adapted to pivot around the curved end of a hinge, said connecting element and a first surface portion of the longitudinal edge of the blade forming an angle less than the angle formed by a wing and a bank of the

hinge profile.

  Thus, the very shape of the connecting element and the hinge wing prevents the connecting element from pivoting beyond a certain angle around

  the curved end of the hinge wing.

  Thus, the louver cannot fold back in direction

  opposite to that provided around the hinges.

  Preferably, said wings of the hinge have a concavity directed towards the outside of said

edges of the hinge profile.

  The wings of the hinge profiles thus form a surface of curvature opposite to that of the curved ends, thus preventing any further pivoting movement of the connecting element.

  around the curved end of the wing.

  According to an advantageous version of the invention, the edges are arranged in the extension of the core of the hinge, said first surface portion of the longitudinal edge of the blade having a radius of curvature substantially identical to the radius of curvature of a

external surface of said banks.

  Thus, in the unfolded position, said first surface portion of the longitudinal edge of the blade can

  perfectly fit a side of the hinge.

  The face of the blade adjacent to the first surface portion of the longitudinal edge is thus arranged in the extension of the core and the edges of the hinge, in the same plane. No opening is apparent at the connection of the hinge and the connection of the blades with the central core of the hinge, preventing the introduction of foreign bodies or

  dirt inside the joint.

  the intention will appear again in the description below

  sliding shutter according to the invention.

  We will first describe a sliding shutter according to the invention with reference to the

figure 4.

  A sliding shutter is made up of several blades 10 associated with one another by

hinges 20.

  The blades 10 extend in a longitudinal direction and a hinge 20 is adapted to

  secure two adjacent boards 10.

  This hinge consists of a profile extending parallel to the longitudinal direction of the blades. In general, this direction

  longitudinal corresponds to the vertical direction.

  This hinge thus forms a hinge profile which fits continuously over the entire

blade height.

  The hinge 20 comprises, in a transverse plane of the profile, a central core 21, two edges 22 substantially in the form of an arc of a circle and two wings 23 with curved end 24, fixed respectively to the

banks 22.

  This hinge 20 is symmetrical with respect to a longitudinal median plane P perpendicular to the core

central section 21.

  The wings 23 extend substantially

  parallel to the central core 21 of the profile.

  The blades 10 have on longitudinal edges a connecting element 12 which includes a curved end 13 adapted to pivot around

  the curved end 24 of the hinge 20.

  The curved ends 24 of the hinge 20 and 13 of the connecting element 12 have a cross section substantially in the form of a semicircle, the internal surface of the curved end 13 of the connecting element 12 conforming to the external surface of the curved end 24 of the hinge 20 so that these curved ends can pivot one by

compared to each other.

  The connecting element 12 and a first surface portion 15a of the longitudinal edge of the blade 10 form an angle less than the angle formed by a wing

  23 and an edge 22 of the hinge profile.

  The pivoting of the connecting element 12 around the edge 22 of the hinge cannot therefore continue beyond a position in which the connecting element 12 is in contact with the wing 23 of the

hinge 20.

  The wings 23 of the hinge have a concavity directed towards the outside of the edges of the profile of

hinge 20.

  In this example, the wings 23 have a section

slightly curved cross-section.

  They could also have a section

transverse rectilinear.

  The wings 23 thus have a slightly concave surface towards the outside of the edges 22 of the profile and form a bearing surface for the connecting element 12 when the shutter is opened in

unfolded position.

  This bearing surface also reinforces the blocking of the pivoting of the blade 10 around the curved end 24 of the hinge beyond its

open position.

  The edges 22 are arranged in the extension of the core 21 of the hinge 20 so that the outer surface 21a of the central core 21 is tangent to the outer surface 22a of the edges 22 in the form of an arc of a circle. The first surface portion 15a of the longitudinal edge of the blade 10 has a radius of curvature substantially identical to the radius of curvature of the outer surface 22a of the edges 22, so that in the unfolded position, the first surface portion 15a of

  S15 the blade matches the external surface 22a of the edge 22.

  The central core 21 of the hinge comprises a rib 26 having an end surface 27, opposite to the central core 21 of the hinge, of cross section of shape complementary to a cross section of a second surface portion 15b of the

longitudinal edges of the blades 10.

  In this example, the cross sections of the second surface portion 15b of the blade and of the end surface 27 are in the form of circular arcs of

identical radii of curvature.

  Thus, in the folded position of the blades 10 around the hinge 20, the second surface portions 15b of the blades come, on either side of the median plane P of symmetry of the hinge 20, the surface

  end 27 of the rib (see Figure 3).

  The thickness of the blades 10, that is to say the distance separating the two faces 11 of the blade 10, is identical to the thickness of the hinge 20, that is to say the greatest distance separating l central core 21 of the

end surface 27.

  Thus, in the unfolded position, one of the faces 11 of each blade 10 is aligned with the central core 21 of the hinge 20 and the other face 11 of the blade 10 is contained in a vertical plane tangent to the end surface 27 of the rib 26 of the hinge 20. In addition, the thickness of the blade 10 is substantially equal to or less than the distance separating the longitudinal median plane of symmetry P of the hinge 21 and the end of each adjacent edge 22

to a wing 23 of the hinge.

  Thus, in the folded position, the blades 10 arranged in two parallel planes have their opposite faces 11 arranged in the extension of said end of each bank 22 of the hinge, as

illustrated in figure 3.

  Thus, as illustrated in FIG. 10, in the folded position, only the central core 21 and the edges 22 of the hinge are visible, the blades 10 being

  included in the width of the hinge profile.

  In addition, the second surface portion 15b of a longitudinal edge of the blade 10 is arranged in the extension of the connecting element 12, this connecting element 12 having a cross section in the form of an arc of a circle of identical radius. to the radius of the second

surface portion 15b.

  In the unfolded position, as illustrated in FIG. 1, the surface portion 15b of the longitudinal edge of the blade 10 forms with the connecting element 12 a groove 16

  of cross section in the shape of an arc of a circle.

  These grooves 16 may have a dimension such that they conform to the shape of the end of a finger, facilitating the cleaning of the shutter deck.

  when the latter is in the unfolded position.

  In addition, the end surface 27 of the rib 26 extends on either side of the median plane P so that the end of the connecting element 12 is substantially adjacent to this surface

end 27.

  Only surfaces in the form of an arc of a circle are thus apparent on a face opposite to the central core 21 of the hinge 20, without projecting connecting members or openings in which

  soiling is likely to accumulate.

  The rib 26 further comprises two longitudinal walls 28 having a cross section in the form of a circular arc and arranged in the extension of the edges 22 of the hinge profile 20, the radius of curvature of the edges 22 and the longitudinal walls 28

being identical.

  The edges 22 and the longitudinal walls 28 of the rib 26 have a cross section in the form of an arc of a concentric circle respectively with the

  center of the curved end 24 of each bank 22.

  The edges 22 and the longitudinal walls 28 thus form a guide surface for the curved end 13 of the connecting element 12 of the blade 10 during its pivoting around the curved end

24 of hinge 20.

  Preferably, the curved end 13 of the connecting element 12 of the blade 10 comprises a projection 14, also in the form of a profiled rib, adapted to be in contact with the edges 22 and the

  longitudinal walls 28 of rib 26.

  This projection 24 makes it possible to reduce the contact surface between the curved end 13 of the blade 10

and the guide surfaces 22, 28.

  All the profiles of the blades 10 and the hinge 20 can be obtained by extruding PVC

  (Polyvinyl chloride) or anodized aluminum.

  In order to reinforce the structure of the hinge 20, it is advantageous to provide in the profile, a zone of excess thickness at the junction of the edges 22 with the wings 23, point for blocking the pivoting of the

blades 10.

  In order not to hinder the cooling of the extruded profile, it is preferable to provide a reinforcing rib 25 extending between each wing 23 and each edge 22 of the profile, and of thickness substantially identical to the thickness of the different

parts of the profile.

  As illustrated in FIGS. 5 and 6, stops 30] 0 are fixed to the ends of the hinge profiles 20, so as to prevent the blades 10 from sliding vertically relative to one another, in the

hinge 20.

  These stops are preferably fixed by screws 33 in a socket 29 provided in the rib 26 of the

  hinge 20, substantially in the center of the rib 26.

  These stops have substantially an external profile corresponding to the contour of the hinge 20 and forming

a full flat surface.

  Nipples 31, four in number in this example, allow, when fixing the stop in the end of the hinge 20, to facilitate the

  centering of this stop and its positioning.

  It is indeed essential that this stop 30 is fixed in the extension of the hinge 20, so that the outer contours of the hinge 20 and

  of the stop 30 are perfectly adjacent.

  The rib 26 is reinforced by two walls 34 arranged in a cross, the point of intersection of which is occupied by the honeycomb 29. These walls 34 define, with the profiled central core 21, the longitudinal walls 28 and the end wall 27 , four spaces in which the four pins of the stopper 30 are housed respectively. As illustrated in FIG. 7, the louver is slidably mounted on rails 40, arranged on either side of a frame 41 with an opening and preferably

in the upper part and in the lower part.

  On a sliding shutter, one in two hinges is further equipped, at each end, with a guide element 43 adapted to slide in each

rail 40.

  These guide elements 43 incorporate stops 30, along a vertical axis Y, at the center of the rib 26. The guide elements 43 thus have a base identical to a stop 30, the base being formed in one piece with the portion adapted to

slide in the rail 40.

  In addition, the axis of rotation X of a blade 10 relative to the curved end 24 of the hinge is slightly offset from the vertical axis Y of the sliding guide elements 43 of the hinge,

as shown in figure 4.

  By way of example, the distance separating the two axes, in a direction perpendicular to the plane of the central core 21 of the profile, is substantially equal to

1.5 mm.

  This arrangement allows the shutter to fold back by itself when it is subjected to a thrust requesting the opening of the shutter, in a direction parallel to the sliding direction

louver in the rails 40.

  As illustrated in FIGS. 8 and 9, the shutter further comprises an end hinge 49, adapted to secure an end blade 10 to a side rail 46, said end hinge 49 having a cross section substantially identical to one half. a hinge 20 located on one side of a longitudinal median plane P perpendicular to the central core 21 of the

hinge 10.

  The end hinge 49 has a fixing lug 47 comprising a bore adapted to the passage

a fixing screw 48.

  It is thus easy to disassemble all of the louvre blades from the guide rails 40 and

  side rails 46 arranged on the sides of the frame.

  Thus, when the louver, manufactured in the factory, is delivered mounted on its guide rails 40 and the side rails 46, it is possible to separate, by a simple screw, the end hinge 45 from the rail

  side 46 and remove the curtain from the louver.

  This rapid removal on site of the folding shutter deck, allows unconstrained access to the frame 41 associated with the rails 40, 46 for sealing between the frame 41 and the main structure (new construction) or the old frame ( renovation of an old building) as well as the cladding

  of the frame 41 after sealing.

  The present invention thus makes it possible to produce a sliding shutter as illustrated in FIG. 10, having both in folded and unfolded position a substantially continuous apparent surface, without elements

projecting.

  As illustrated in FIG. 10, in the folded position, only the central core 21 and the edges 22 of each hinge 20 are visible, the hinge profiles being disposed adjacent to each other.

to others.

  It will be understood that each blade 10, as illustrated in FIG. 4, has connection ends and longitudinal edges configured in an opposite manner, symmetrical with respect to a central vertical axis of the blade, in order to allow several successive blades to be

articulated by a hinge 20.

  In the open position of the shutter, each face of the deck successively has a first flat blade 10, the central core 21 of a hinge 20, a second flat blade 10 extended by a groove 16, an end surface 27 of the rib of a hinge 20, a second groove 16 of a third flat blade, again the central core of a hinge ..... Of course, the invention is not limited to the examples described below above and many modifications can be made without leaving the

part of the invention.

  Thus, the connecting elements 12 with a curved end 13 equipped with a projection 14 could be in the form not of profiles but in the form of discrete connecting elements 12, distributed over

a longitudinal edge of the blade 10.
