Definitions

  • the invention relates to an assembly of a clamping ring and a shutter tube link, able to surround a winding tube of the shutter apron, the tube link comprising in a direction parallel to the axis of the winding tube at least one lateral extension which has on one side a fastening means of one end of the ring, and on the other side a step-adjustable fastening device capable of cooperating with means conjugate hooking provided at the other end of the ring.
  • the gripping device steplessly adjustable and the coupling means are generally formed by a notching system, in particular with teeth and hollow. It is thus possible to vary the perimeter of the ring-link assembly to tighten the winding tube as close as possible, in order to ensure the rotational drive.
  • the tube link is usually part of an automatic lock consisting of several links articulated between them and able to be arched to prevent unauthorized raising of the deck.
  • an automatic shutter latch is described and claimed in the French patent application no. 07 04615 filed June 27, 2007 in the name of the same Applicant Company.
  • US 5,964,013 relates to a link for attaching a bundle of cables.
  • This link has an elastic section 4 which is folded substantially at 180 °.
  • the cable tie of this prior document does not correspond to the field of the invention which concerns a ring of a roller shutter tube link.
  • FR 2778692 relates to an articulated device connecting the deck of a roller shutter to its winding shaft, the grouped action of several identical copies is to transmit on the top of the deck, a crushing force adapted to ensure the condemnation of the shutter. closed position.
  • the transmission of the torque between the tube and the automatic lock comprising the tube link maintained by a clamping ring as defined above depends in particular on the quality of the tightening exerted by the ring or rings.
  • the notch between the ring and the link is formed on one side by a multitude of teeth provided on the ring and, on the other side, by a multitude of hollow reservations provided on the link. This results in a minimum “step” of displacement between two possible attachment positions, determined by the rating minimum achievable between two tops of teeth. It may happen that the tightening obtained by closing the ring is insufficient and that a greater tightening step by step can not be ensured due to too high tension to exert on the ring.
  • the invention aims, above all, to provide a set of a tube link and a ring which allows to exert effective tightening even under the conditions mentioned above.
  • the invention also aims to provide a set of a tube link and a clamping ring which ensures good torque transmission between the tube and the tube link fixed to the tube with the aid of one or more clamping rings.
  • an assembly of a clamping ring and a roller shutter tube link is characterized in that the ring comprises, projecting on at least one zone of its internal surface, a elastic support means against the wall of the winding tube, the radial stroke of crushing of this elastic means being sufficient to obtain, at the end of the ring provided with the conjugate coupling means, a moving towards the other upper end at the pitch of the adjustable fastening device.
  • the resilient support means has a radial crushing stroke which makes it possible, after closure of the ring, to obtain a residual prestressing between the coupling device and the conjugate fastening means.
  • the resilient support means is formed by at least one lining of elastomeric material fixed, in particular by gluing or bi-injection, against the inner surface of the ring.
  • the clamping ring may comprise, projecting on its inner surface, at least one rigid abutment of a thickness less than that of the uncompressed elastic support means, but sufficient to limit the compression of this elastic support means.
  • the radial crushing stroke of the resilient support means may be between one quarter and one fifth of the pitch of the attachment device.
  • the zone in which the resilient support means is provided is, at least in part, substantially diametrically opposed to the attachment device.
  • the invention also relates to an automatic safety lock, for roller shutter comprising a tube link attached to the tube with at least one clamping ring, the tube link and the ring forming an assembly as defined above.
  • the invention also relates to a shutter whose fixing on the winding tube is made using at least one safety lock provided with at least one set of a clamping ring and a tube link as defined above.
  • a clamping ring B of a roller shutter tube link 1 can be seen, this ring B being suitable for surrounding a winding roller shutter tube 2.
  • the tube 2 has an octagonal cross section. This example is not limiting, the section may be circular or polygonal with a number of sides different from eight.
  • the tube link 1 has a substantially cylindrical outer surface generatrices parallel to the geometric axis XX of the tube 2 when the link is in place on the tube.
  • the tube link 1 may be part of an automatic safety lock A comprising an apron link 3 and an intermediate link 4.
  • the rolling shutter apron (not shown) consists of blades hinged together, the upper blade being attached to a bar 5 of the deck link 3.
  • the links 3, 4, 1 of the lock A are hinged together so as to cause an arching, when the apron is fully deployed and the tube winding 2 is stopped in rotation by an operating system. This bracing makes it possible, in particular, to prevent unauthorized raising of the deck from the outside.
  • the tube link 1 comprises, in a direction parallel to the geometric axis XX of the tube 2, at least one lateral extension 6 ( Fig. 2 ).
  • an extension 6 is provided on each side of the link 1 so that when this link tube 1 is fixed on the tube 2, the extensions 6 are on either side of the link in the longitudinal direction of the tube 2.
  • a clamping ring is placed on each side of the link.
  • Each lateral extension 6 comprises an attachment means 7 at one end 8 of the ring B.
  • the attachment means 7 is advantageously constituted by a substantially rectangular window 9 ( Fig. 2 ) having a bar 10 parallel to the direction of the generatrices of the link 1.
  • the end 8 of the ring is formed in the form of a hook 11 which can engage in the opening of the window 9 to catch on the bar 10.
  • the side of the extension 6 opposite the window 9 comprises a hooking device 12, adjustable step by step, adapted to cooperate with conjugate hooking means 13 provided at the end of the ring B opposite the hook 11.
  • the attachment device 12 comprises a housing 14 open laterally, on the opposite side to the link 1.
  • the housing 14 is also open at its end remote from the window 9.
  • At least the lower face 14a of the housing, close to the tube 2, is provided with a series of teeth 15, separated by recesses 16 ( Fig.3 ) following a step p .
  • the edges of the teeth 15 are oriented parallel to the bar 10.
  • the end 17 of the ring B opposite the end 8 is provided on its face turned radially inward, attachment means 13 formed by a succession of notches of the type "tail of fir". Notches are determined by troughs 18 ( Fig.3 ) and conjugate teeth 19 of the teeth 15 and recess 16 of the housing 14. It is thus possible to ensure the closure of the ring B by engaging the teeth 19 and the teeth 15 by engagement through the lateral opening of the housing 14. In a variant, it is possible to provide notches on the two internal faces facing the housing 14, as well as on both faces of the end 17 of the ring.
  • the walls of the housing 14 are integral with the link 1 by their edges adjacent to this link, and are sufficiently rigid to keep the distance between them substantially constant.
  • the clamping rings B thanks to the steplessly adjustable hooking device 12, can be adapted to different tube models and to different diameters.
  • the notching system makes it possible to vary the perimeter of the B-link 1 ring assembly in order to tighten the winding tube 2 as closely as possible in order to ensure the rotational drive.
  • the transmission of the torque between the tube 2 and the links of the lock A is generally done by cooperation of pins or lugs (not visible in the drawings) provided under the link and engaged in openings of the tube, and / or by obstacle due to the conjugation of the polygonal shapes between the tubes 2 and the rings B.
  • the teeth 19 of the ring advance one by one over the troughs 16 of the link up to maximum tightening.
  • the teeth 19 of the ring are about to advance an additional notch, as shown in FIG. Fig. 7 descending into the next recess 16, but the tension exerted on the ring is too high; the teeth 19 then return to the previous hollows. This results in some clipping play (or engagement) and decreased clamping force.
  • the or each clamping ring B has, projecting from at least one zone of its inner surface, an elastic support means E ( Figs. 4 and 5 ) against the wall of the winding tube 2.
  • the radial stroke dr crushing of the resilient means E is selected sufficient to achieve at the toothed end 17 of the ring, a circumferential displacement ⁇ L on the other end 8, greater than the pitch p of the recesses 16 and teeth 19 (see Fig. 8 ).
  • the zone in which the elastic means E is provided is at least in part substantially diametrically opposed to the attachment device 12 and the end 17 of the ring.
  • the scheme of Fig. 8 illustrates the relationship between radial crushing dr and the peripheral displacement ⁇ L of the end 17.
  • the ring B extends along a circumference of radius r.
  • the ring B is made of a material that can be considered as inextensible, so that the ring B retains its length.
  • the estimate is only approximate, in particular because the ring B may not completely surround the tube 2, and because the radial crushing is not necessarily regular over the entire periphery.
  • the displacement ⁇ L is amplified with respect to the radial crushing.
  • the resilient support means E allows, by its compression, the entry of the teeth 19 into the foremost recesses 16 (see FIG. Fig.7 ). At the time of the retraction of the end 17 of the ring under the effect of the elastic return, the elastic support means E ensures a residual tension between the teeth 19 of the ring B and those 15 of the tube link 1.
  • the resilient support means E can be compressed. It is also necessary that its radial crushing stroke dr allows to obtain a displacement ⁇ L greater than the pitch p of the hollows and teeth.
  • the radial crushing stroke dr of the resilient support means is advantageously between one quarter and one fifth of the pitch p of the attachment device, so that ⁇ L estimated previously at 6.28 dr will be greater than the pitch p .
  • the elastic support means E is formed by at least one lining 20 ( Fig.4 and 5 ) of elastomeric material fixed, in particular by bonding or bi-injection, against the inner surface of the ring B.
  • the elastomer seal 20 is injected directly against the ring B by bi-injection technique, that is to say say that the injection press has two different feeds of different raw materials that it injects into the same mold, which allows to achieve the part in a single operation, without subsequent recovery of completion.
  • the lining 20 can be made in the form of a strip, as illustrated on Fig.4 and 5 , or pavers, or any other suitable volume.
  • the ring B has protruding on its inner surface at least one rigid abutment 21 ( Fig. 4 and 5 ) of thickness h1 ( Fig. 5 ) less than the thickness h2 of the uncompressed elastic support means E, and in particular of the elastomer seal 20, for limiting the deformation of the elastic means when a resistive torque is applied to the lock A.
  • the crushing forces of the elastomer seal 20 at the time when the tube 2 tends to rotate in the rings B are much higher than those developed during clamping at the time of assembly.
  • deformation limiters at the level of the elastomer linings 20 in order not to destroy the adhesion function of the product and to keep the envelope geometry of the tube over the entire inner periphery of the ring to withstand the torque of rotation.
  • the projecting portion 21 may be constituted by a rib oriented perpendicularly to the geometric axis of the ring and provided in the central region of the inner surface of the ring over a part of the length.
  • the lining of elastomeric material 20 then has two branches flanking the rib 21.
  • the lining (s) 20 of elastomeric material make it possible, not only to recover the clipping play of the adjustable closure system between the ring B and the link tube 1, but also to avoid, or at least to delay, the beginning of sliding of the rings B relative to the tube 2 because of the high coefficient of adhesion between the elastomeric material and the tube. This prevents the linings B tend to turn on the tube 2 by deformation, especially in the case where the outer shape of the tube 2 is close to a cylinder.
  • a catch zone 22 ( Fig.6 ), in particular formed by a lug 22a.
  • This lug 22a has substantially the shape of a rectangle trapezoid whose side remote from the other end 8 of the ring is orthogonal to the peripheral edge of the ring.
  • the hooking zone 22 can be grasped by a tool for clamping the ring on the link 1.
  • a corner zone 23 is provided on the link 1 for the grip by the tool.
  • the clamping distance G corresponds to the distance between the zones 22 and 23.
