Definitions

  • the present invention relates to a panel with blades, in particular for closing wall openings, of the type comprising a number of blades mounted to slide in two parallel guide paths extending on two opposite sides of the frame of the panel. to be able to be moved between a first position in which they are placed in mutual contact between the guide tracks and a second position in which they are stored in a box mounted on a third side of the frame, this box containing means for transform the longitudinal movement of the blades between the guide tracks into a transverse movement inside the box.
  • Such slat panels are essentially used as shutters for closing window openings or French windows, shutters in which the means for transforming the movement of the slats allow the latter to come side by side inside of the box, the size of which can thus be considerably reduced compared to that of the boxes of conventional roller shutters.
  • the blades are without any connection between them and the mechanism for controlling their movement simply exerts traction on the lowest blade which therefore pushes all the other blades into the box where they come to be stored.
  • the mechanism for controlling their movement simply exerts traction on the lowest blade which therefore pushes all the other blades into the box where they come to be stored.
  • side by side thanks to one or more guide rails curving towards the vertical bottom wall of the box and cooperating with lugs provided on the side edges of the blades.
  • the controller mechanism since once in the closed position of closure between their guide paths, the blades, other than the lower blade, are free from any relative movement, the gears, other than the lower blade, are free from any relative movement, the gear with blades of this type must, in order to be at shelter from attempted break-ins from the outside, have a locking system that prevents any upward movement of the stack of blades without using the control mechanism.
  • the present invention proposes to remedy this drawback and, to do this, it relates to a laminated panel of the type specified in the preamble which is characterized in that the blades carry, along their adjacent contact edges, means releasable mutual locking device comprising at least one movable element which, under the request of a thrust member made operational by the passage of the lamés in their first position, is moved to make the locking means active and which, as soon as the biasing of the thrust member at the start of the movement of the blades from their first to their second positions, is moved in the opposite direction to release the locking means.
  • the locking means which act to secure the lamés mutually in the joined position thereby preventing any attempt to break in from the outside, cease to act as soon as the blades are moved towards the box, so that their change of trajectory inside it can be done without hindrance, just as in conventional louvre panels not fitted with such locking means.
  • the locking means comprise, in each pair of adjacent blades, at least one rib formed over a part of the length of the contact edge of one of the blades and cooperating with a groove complementary formed in that of the second blade, as well as at least one elastic member forming said movable element, this elastic member being fixed on the contact edge of one or the other of the two blades near the rib or the groove thereof and having a stiffness such that it can be compressed between the contact edges of the two blades under the stress of the pushing member and that it can relax when it ceases.
  • the thrust member is constituted by an additional loading blade, disposed at the head of the series of blades considering their direction of movement from the first in the second position, this load blade remaining permanently inside the box and being completely devoid of locking means on its edge of contact with the next blade.
  • the loading blade together with the following blade, strongly presses on the stack of blades in the closed position and thus compresses the elastic members located between them, so that the ribs are fitted into the associated grooves to ensure mutual locking of the blades.
  • the loading blade devoid of locking means
  • the elastic members dislodge the ribs from the associated grooves and thus unlock the blades which can therefore be stored side by side in the box.
  • the fact that the loading blade is devoid of locking means does not authorize, when the shutter is lowered, any attempted break-in at its level of contact with the next blade since this area is inside the cabinet.
  • the locking means comprise several ribs formed at equal intervals along the contact edge of one of the blades and several elastic members respectively disposed between these ribs, to ensure the inviolability of the flap over its entire width.
  • each elastic member comprises a spring received in a housing formed in the contact edge of the blade which carries it, as well as a U-shaped pusher element secured to the free end of the spring and coming to cover said contact edge when the spring is compressed.
  • This type of elastic member has both the advantage of exerting an effective thrust between two adjacent blades, when the load blade no longer acts, and of being completely erased otherwise to allow total insertion ribs in the corresponding grooves and thus ensure effective mutual locking of the blades.
  • each pair of adjacent blades the part the contact edge of the second blade intended to bear against the pusher element is capped by an identical U-shaped element, made of the same material as the latter.
  • the purpose of this arrangement is to reduce to a minimum the friction between each blade and the next, during its change of trajectory in the box.
  • the blade panel according to the invention is characterized in that the mutual locking means of the blades consist of at least one series of rods which are respectively carried by all the blades, except for the first to enter the box, so that it can slide in the same plane, these rods being dimensioned and retained against any sliding out of the blades so as to be inside the edges thereof when they are moved from their first to their second positions, with the exception of the rod of the last blade to enter the box, which protrudes from the latter to come into abutment against the thrust member preferably constituted by the support of the panel, as soon as the blades arrive in their first position, in that the rods have, on either side of the contact planes of the blades, ends of complementary shapes, and in that the first blade to penetrate into the box has, s ur its edge of contact with the next blade, an interlocking member placed in the same plane as the rods, the series of rods being possibly associated with a return means, acting in the opposite direction to the direction of movement of the blades of their first to
  • the rods are slidably mounted inside the blades and the interlocking member is constituted by a recess formed in said contact edge of the first blade, the return means being formed by a spring housed in this recess and able to be applied against a shoulder of the stem of the next blade.
  • the means for transforming the movement of the louvers consist of guide rails which curve towards the bottom of the box and cooperate with lugs carried by the edges of each blade which slides in the guideways, in half of it which first penetrates into the box.
  • the invention provides in addition two guide cams which curve towards the bottom of the box and cooperate with second lugs fixed on the edges of each blade provided with the first lugs, close to the contact edge of the latter, which enters the casing last.
  • each blade automatically tilts towards the bottom of the box as soon as it has been completely inserted into it and is thus automatically detached from the next.
  • a blocking system capable of ensuring locking, on at least one of the guide paths, of the first blade to enter the box, when the panel is completely out of the latter.
  • the shutter shown in Figure 1 is intended to close a bay (1 formed in a wall 2 of any construction. Along the inner face of the wall 2, the bay 1 is equipped with a frame 3 for a window 4 .
  • the shutter itself essentially consists of a number of rectangular blades 5, generally made of wood or plastic, each slidably mounted by their small vertical edges 5e, in two parallel vertical slides 6 fixed on either side of the opening, applied to the frame 3 of the window 2.
  • the blades 5 carry, at the same height, on each of their vertical edges 5e, a lug 7 housed in a respective slide 6 and are completely independent of each other, without any link between them.
  • the pins are located at the top of the edges 5e of the blades 5.
  • the blades 5 can, under the action of a control mechanism which will be described in more detail below, be moved upwards along the slides 6 so as to be rare in a box 8 arranged at the upper part of the bay 1.
  • a guide rail 9 comprising a first vertical section 10 which curves in 11 towards the bottom wall 12 of the box, which is here front wall, in the form of a second section 13 inclined at an n g obtuse relative to to the vertical section 10.
  • the two guide rails 9 are parallel over their entire length, and the free space which they delimit 'between them is of a width slightly greater than the length of the blades 5
  • the wall of wave 12 of the box 8 extends in a vertical plane on the outside of the b L e 1 and has a height barely greater than that of the blades.
  • the bottom wall 1 4 of the box in which is formed the insertion slot 15 of the blades located very close to the window 4, is in turn parallel to the inclined sections 13 of the guide rails 9 and is spaced from the latter by a distance of barely greater than that which on each blade 5, separates a lug 7 from the lower end of the latter.
  • the shutter control mechanism is essentially constituted by a pin 16 fixed between the two side walls of the box 1, in the upper rear corner thereof, just opposite the insertion slot 15.
  • This axis is capable of being rotated, in a manner known per se, by means of an oscillating crank rod 17 accessible from the interior of the construction.
  • each of the ends of the axis 16 comprises a coil 18 on which is wound an elongated drawing element, here constituted by a nylon tape 19, which extends parallel to the two lateral branches 6a, 6b of the slide respective to attach to a special lug 20 located at the base of the corresponding vertical edge of the blade 1a: lower 5a.
  • this control mechanism by exerting traction on the lowest blade 5a which carries with it all the others upwards, ensures a side-by-side storage in vertical position of the blades 5 in the box 8, in combination with the curved guide rails 9 on which the blades 5 slide by their lugs 7, pushing each other towards the bottom wall 12 of the casing 8.
  • This method of storing the blades illustrated in FIG. 2 makes it possible to reduce the maximum size of the box and give thickness to the blades, in particular to provide them with thermal insulation.
  • the component according to the invention is equipped with such a blocking system which will now be described with reference to Figures 3 to 6. '
  • this locking system consists of an elastic metal strip 21 which has been subjected at 22 to a twist of 90 ° to present, on the one hand, at its base a bearing surface 23 by which it is fixed, by means of screws 24, on one of the vertical edges 5e of the highest blade 5b of the shutter, above the lug 7, and, on the other hand, a high elastic part 25 which, when the flap is fully lowered, faces the inner branch 6b of the corresponding slide 6, being normally biased against the latter.
  • this elastic part 25 of the strip 21 is folded at a right angle in the direction of the inner branch 6b of the slide, along only part of its upper free edge, so as to define a pawl 26, which in said lowered position of the flap, is placed opposite a light 27 formed in the upper part of the inner branch 6b of the slide 6.
  • the pulling tape 19 extends between the inner branch 6b of the slide and the elastic part 25 of the strip 21 and more precisely in front of the part without pawl of the free edge of the latter.
  • the flap is unlocked automatically when its upward movement is initiated.
  • the ribbon 19 is stretched gradually to return to its vertical position and, by its contact with the strip 21, move it away from the inner branch 6b of the slide 6, so that the pawl 26 is extracted from the light 27, as shown in FIG. then, the highest blade 5b of the shutter is unlocked and if one continues to rotate the axis 16, the shutter is raised as described above. It will be added here that to avoid, during the initiation of the movement for raising the flap, any risk of blocking by contact of the pawl 26 with the upper edge 28 of the slot 27, a slight clearance 29 is provided between the latter and the pawl 26. '
  • this blocking system is not sufficient to give the shutter a character of total inviolability, because in fact the blades, which simply rest on one another in the closed position of the shutter, can be easily forced , especially if they are very long, by a push from the outside towards the inside of the shutter.
  • the present invention overcomes this drawback by proposing, in combination with the locking system which has just been described, releasable locking means acting along the two contact edges of two adjacent blades of the shutter.
  • these locking means comprise, in each pair of adjacent blades 5c, 5d, several ribs 30 formed at equal intervals along the contact edge 31 of the lower blade 5d to cooperate with grooves 32 of complementary shape formed in the contact edge 33 of the upper blade 5c. Between the ribs 30 of the lower blade, there are also arranged elastic members 34.
  • Each of these is formed by a helical spring 35 which bears against the bottom of a cylindrical housing 36 hollowed out in the contact edge 31 and which carries at its free end a pusher element 37, produced in the form of an elongated element in U made of plastic and dimensioned so as to come over the contact edge 31 of the blade 5d between two successive ribs 30, when the spring 35 is fully compressed. It will also be observed that the part of the contact edge 33 of the upper blade located opposite the pusher element 37 is capped by a U-shaped element 38 in all respects identical to the latter.
  • the highest blade 5 f in fact constitutes an additional load blade, substantially of the same weight as the other blades.
  • This loading blade 5 f is further dimensioned so as to always be inside the box 8 and even well above the insertion slot 15 of the latter so that its contact area with the next blade 5b is inaccessible from the outside.
  • Figures f and 8 also show that the vertical edges 5e of the blades all carry, near their base and on their outer side, a second lug 41 suitable, during the introduction of each blade into the box 8, to come to the contact of a guide cam 42 curved towards the bottom wall of the box.
  • the locking means which have just been described act in the following manner.
  • the loading blade 5f is moved towards the bottom wall 12 of the box under the thrust of the lower blades, this movement being made possible by the bevelled shape of the contact edges 39 40.
  • the load blade 5f being thus extracted from the stack, the springs 35 are relaxed so that, in each pair of adjacent blades, drive the upper blade 5b upwards via the push elements 37 and thus dislodge the ribs 30 grooves 32 as shown in Figure 9.
  • the blades 5 are unlocked and, after their introduction into the housing 8, they can therefore be pushed successively unimpeded towards the bottom wall 12 of the latter.
  • This change of trajectory of the blades 5 is obtained thanks to the inclined sections 13 of the guide rails 9 which cooperate with the lugs 7 of the blades, but also thanks to the guide cams 42 which cause the bottom of the blades to tilt when their second lugs 41 come into contact. contact with these guide cams.
  • this change of trajectory is done smoothly by the fact that, when it occurs, the blades are in contact only by their U-shaped elements 37 and 38, which being made of plastic material reduce friction.
  • the springs 35 must have a stiffness allowing them at the same time to be completely compressed between the contact edges 31, 33 of the blades 5 under the pressure of the load blade 5f and relax completely when this pressure stops.
  • Figures 10 to 12 illustrate a second embodiment of the shutter locking means according to the invention, respectively in front view in their active position and in cross section in their active and inactive positions.
  • the locking means are constituted on each blade 5, with the exception of the upper blade 5b, by several vertical rods 43 mounted to slide freely in the blade and distributed at equal intervals over the entire length of the latter while being positioned respectively in the same vertical planes as the rods 43 of the other blades.
  • Each rod 43 with the exception of those of the lower blade 5a, is of a length very slightly less than the height of the blade which carries it and has a conical upper end 44 and a lower end 45 hollowed out in a complementary form.
  • the rods 43a of the lower blade 5a have a length greater than the height of the latter and, if they also have a conical upper end 44a, their lower end carries a stopper 46.
  • the rods 43a are also retained against any sliding down inside the blade 5a so that, when the latter is raised, their lower end clearly protrudes from the lower edge 47 of the blade 5a and their upper end 44a is slightly inside the upper edge 48 of the latter.
  • the rods 43 of the upper blades are retained in the same way in the latter, but in such a way that, when the lower blade 5a is raised, they are entirely housed inside their respective blades.
  • the upper blade 5b is provided with conical recesses 49 formed in its lower edge 50 at points situated respectively in the vertical planes of the rods 43.
  • these recesses 49 retain each) a spring 51 capable of coming to apply against there corresponding rod 43 of the next blade 5g.
  • This second embodiment of the locking means acts as follows.
  • the blades are unlocked automatically at the start of the flap up movement. Indeed, as soon as the lower blade 5a is raised, the rods 43, 43a, in mutual interlocking, slide in the blades under the effect of gravity and the thrust of the springs 51 until they are outside the zones of blade contact (see figure 12). After their introduction into the box, they can therefore be pushed unhindered towards the bottom wall 12 of the box 8 in the manner described with reference to the first embodiment. It should be noted here that, to favor the change of trajectory of the blades in the box, one can do without the guide cams 42 and the pins 41, giving the contact edges of the blades the form of complementary bevels.
