Definitions

  • the invention relates to a profiled blade for curtain closure and a corresponding closing curtain.
  • the document FR-A-2,687,724 discloses a one-piece profiled strip for curtain closure, according to the preamble of claim 1, of substantially trapezoidal cross section having a housing adjacent to the small base and a first side of said section and a rod of rigid material connected to the angle of the small base and the second side by a hinge band flexible material and inextensible width substantially equal to the difference in width of the large base and the small base.
  • the document DE-U-8706209 describes a curtain of assembled blades each formed of several modules, each cross section substantially hexagonal, interconnected by a flexible and inextensible hinge band. This strip is located substantially at the corner of two adjacent sides of each module, parallel to and spaced apart from the side intended to come into contact with a slideway. The side of the blade in contact with the slide is subjected to permanent friction during its sliding.
  • EP-A-0 596 389 (The state of the art according to Article 54 (3) EPC) shows a profiled blade having on one side a flexible band separated from the small curved base, and a connecting rod. Each blade has an upper section and a lower section connected via a hooking or retaining means. The upper section has a trapezoidal shape.
  • the object of the invention is to improve profiled blades by proposing a blade subjected to a minimum of friction during its sliding opening or closing and in which the hinge strip is not subject to wear during these repeated maneuvers, but only subject to tensile or flexural stresses compatible with long-term operation.
  • the invention proposes a single-piece profiled strip for curtain closure, intended to be mounted transversely, at least one free end in at least one slideway to be guided by it and slide therein, exhibiting at least one substantially trapezoidal transverse cross section, of the type comprising on at least one of its sides a flexible and inextensible hinge band, coextruded with the rigid material of the blade and a connecting rod, characterized in that each hinge strip is located between the bases of the section and in a position away from the small base and in that the small base has a curved profile, so as to slide in the slideway substantially on one or two generators.
  • the blade has a rib on one side and a complementary shape groove on another side. This rib and this groove have a game on the side of the small base.
  • the small base has a curved convexity profile turned towards the inside of the section of the blade so as to slide in the slideway substantially on two generatrices for each section, corresponding to the angles limiting the small base of each section with its sides.
  • the small base has a curved profile convexity turned outwardly of the section of the blade, so as to slide in the slide substantially on a generator located in the middle part of the small base.
  • Each band is located substantially in the middle of the side connecting the two bases.
  • the connecting rod is intended to slide with play in a housing of an adjacent blade for the assembly of the curtain, and the appendix of the connecting rod is adapted to an opening of the corresponding housing so as to avoid any elongation of the curtain. traction.
  • the large base of the blade has on its inner face a longitudinal rib directed towards the inside of the blade section.
  • it may comprise on its outer face a groove located opposite said rib.
  • the blade comprises at least two sections each substantially trapezoidal coextruded with one (or more) hinge strip between them.
  • the invention also relates to a closing curtain made by assembling blades according to the invention.
  • the blades being assembled to each other and following each other by cooperation of a rod in a housing, the curtain being mounted transversely to at least one free end of the blades in at least one slideway to be guided by it and slide in it.
  • the strips are separated from both banks of the slide.
  • a slide has at least one angled portion having a contour shaped circular portion.
  • the bank of the angled part of smaller radius cooperates with the small base while the bank of larger radius cooperates with the large base.
  • a profiled blade 1 for curtain closure has a hollow cross section and substantially trapezoidal or pseudo-trapezoidal in rigid material, for example plastic of the polyvinyl chloride type.
  • Such a blade is intended for the realization of a curtain 17 closing, the opening of a piece of furniture or other similar application.
  • the blades 1 are assembled to each other and following the others.
  • Such blades 1 are intended to be mounted transversely, at least one free end (and generally at both free ends) in at least one slide 18 to be guided by it and slide therein.
  • the section of the blade has a large base 2 located on the visible side of the curtain when it is mounted and closed and a small base 3, connected to each other by a first side 4 and a second side 5.
  • the large base 2 is substantially flat and has on its inner face 2c a longitudinal rib 6 directed towards the inside of the section of the blade 1.
  • the rib 6 provides a stiffening effect of the body of the blade.
  • the large base 2 further comprises, on its outer face 2d, visible when the curtain is mounted and closed, a groove 7 of complementary shape to the rib 6, intended to improve the aesthetic characteristics of the blade 1.
  • the small base 3 has a convex profile turned towards the inside of the blade so as to define two generatrices 8 and 9 corresponding to the angles limiting the small base 3 with the sides 4 and 5 respectively. These angles are preferably rounded concavity turned towards the inside of the section of the blade.
  • the generatrices 8 and 9 form the contact lines of the blade with the slide 18. Sliding only on two generatrices 8 and 9 reduces to a great extent the friction opposing the sliding of the curtain of blades in the slide or slides 18.
  • the small base 3 could have a concavity profile turned inwardly of the section of the blade.
  • the small base would then comprise only one line of contact with the slide, located in the middle part of the small base 3.
  • the first side 4 comprises, inside the section, a circular housing 10 having an opening 11 opening into the first side 4 and having a direction substantially parallel to the bases 2, 3.
  • the housing 10 and the opening 11 are intended to receive a rod of rigid material as described below.
  • the first side 4 also comprises towards the large base 2 a recessed groove 12 substantially adjacent to the housing 10 for the cooperation of a complementary rib, as described below.
  • the second side 5 has an appendage 13 directed towards the outside of the blade section and to which is connected a strip of flexible and substantially inextensible material 14 coextruded with the body of the blade and at the opposite end of which is connected a rod 15 of rigid material, preferably identical to the material in which the blade is made.
  • the ring 15 is connected to the band 14 by an appendix 15a of dimensions substantially equal to those of the appendix 13 and of slightly greater cross-sectional width than that of the band (the transverse width being counted in the direction perpendicular to the bases 2, 3 ).
  • the length of the strip 14 is substantially equal to a quarter of the difference between the length of the large base 2 and that of the small base 3 (lengths counted in the plane of the figure 1 ).
  • the housing 10 and the appendix 13 are separated from the small base 3 and the large base 2 and are located in the middle part of the sides 4 and 5.
  • the second side 5 also has towards the large base 2 and near the appendix 13 a rib 16 directed projecting outwards from the blade section and located substantially at the same distance from the large base 2 as the groove 12
  • This rib 16 is intended to fit into a groove 12 of an adjacent blade, when a first blade is associated with an adjacent blade by inserting the rod 15 of the first blade into the housing 10 and the opening 11 of the blade. the second blade, so as to form a curtain, and when the latter is closed, the large bases 2 successive blades then being substantially coplanar.
  • the adaptation of the rib 16 in the groove 12 thanks to their complementary shape to each other prevents the insertion from the outside of the blades and the large bases 2 of a cutting instrument likely to cut or break the band 14. It allows the support of the contour 16a of the rib 16 on the contour 12a of the groove 12 which ensures a good flatness of the visible face of the realized curtain, the large bases 2 of the successive blades being coplanar.
  • the sides 4 and 5 respectively comprise two sections, namely a first section 4a, 5a adjoining and substantially perpendicular to the large base 2 and a second section 4b, 5b adjacent to the small base 3 being inclined on it with an obtuse angle.
  • the two sections of each pair of sections 4a, 4b, 5a, 5b are separated from each other by the groove 12 and the housing 10 on the one hand, the rib 16, and the appendix 13 on the other hand .
  • the sections of the ring 15 and the housing 10 are of complementary shapes and have respective dimensions determined with a clearance sufficient for mounting the ring 15 can slide in the housing 10 so as to allow the assembly of the closure curtain in position inclined substantially in the form of a parallelogram then raising the curtain to put it in place without risk of jamming in a guide rail 18.
  • the dimensions of the appendix 15a and the opening 11 are provided so that the appendage 15a of a blade is housed in the opening 11 of the adjacent blade, without excessive substantial play to ensure that the traction the curtain during opening and closing does not produce side play causing a possible lack of flatness of the visible face of the curtain (large bases 2).
  • the blade is made by assembling two transverse trapezoidal or pseudo trapezoidal cross sections 1a, 1b joined to one another by a flexible and inextensible hinge band 14b coextruded with the rigid material of the two sections. .
  • This band 14b connects the two sections 1a, 1b by appendices 13a and 13b.
  • the invention extends to the case of any number of sections as described joined together by hinge strips coextruded with the rigid material of the trapezoidal sections.
  • One of the end sections 1a has on its side 4 a housing 10.
  • the opposite section 1b has on its side 5 a rod 15 connected to this section by a band 14a attached to an appendix 13.
  • Each hinge strip 14a or 14b is substantially of the same size and is located between the small base 3a, 3b and the large base 2a, 2b, in a position spaced from the small base 3a or 3b which corresponds to the invisible and inaccessible face of the curtain once mounted.
  • the two sections 1a, 1b bear against one another at the place, in the first place, of the first sections 24a, 25a of the sides 4a, 5a, situated opposite and in close proximity to one another. , adjacent to the large bases 2a, 2b.
  • a clearance j is formed between the rib 16 and the groove 12 opposite the large bases 2a, 2b and therefore on the side of the band 14b, so as to allow clearance without blocking a section relative to another section in a turning situation.
  • a curtain 17 made from several blades such as those shown on the figures 1 and 2 , assembled to each other and following each other by cooperation of a rod 15 in a housing 10.
  • the curtain 17 is shown in a 90 ° turn situation by means of a slideway 18 having two branches 18a, 18b, each rectilinear and perpendicular to the other, joined to each other by an angled portion 18c having a contour in the general shape of a quarter circle.
  • the presence of the hinge strips 14, 14a, 14b substantially in the middle of the neutral line corresponding to the rotation of the curtain 17 ensures a great ease of sliding by reducing the friction which also avoids excessive or premature wear due to the no contact of the strips with the slide 18. Indeed, it will be observed that the hinge strips between blade sections or between blades are spaced from the two banks 19a, 19b of the slideway 18.
  • a slide 18 has in transverse cross-section a general U-shape with a core facing which is the free end portion of each blade and two banks 19a, 19b facing the bases 2, 2a, 2b, 3, 3a, 3b respectively.
  • a curtain such as 17 is shown in a slide 18 forming on itself an angle of about 180 °.
  • This slide 18 comprises in fact two branches 18a, 18b substantially parallel and spaced apart from each other, joined by a bent portion 18d having a generally semicircular contour.
  • hinge strips 14, 14a, 14b substantially towards the middle of the blade and away from the two banks 19a, 19b of the slideway 18 ensures a great ease of sliding and to obtain a small radius winding corresponding to a tight winding, which significantly reduces the size of the slide 18 - the two branches 18a, 18b are close to one another - and the curtain 17 wound and thus increases the volume available to the interior of the cabinet closed by the curtain 17, while keeping the sliding characteristics of the prior art obtained with upper ray slides.
  • the bank of the angled portion 18c, 18d of smaller radius namely 19b cooperates with the small base 3 while that the bank of larger radius 19a cooperates with the large base 2.
