  • This implementation is relatively complex and requires use accessories likely to be lost on a construction site.
  • the positioning of the tube on its supports implies that one of these supports or an end of the tube is telescopic to allow an axial offset of these elements when installing the winding tube in the installation.
  • DE-A-196 30 744 discloses a tube formed of two parts each provided with a blocking element special designed to cooperate with a special mounted support on a cheek of a box.
  • This system induces the use supports and special tips which are more complicated and more expensive than those conventionally used.
  • the special nature of these supports and end caps makes them more complex maintenance and / or replacement of certain parts of the tube.
  • the solution presented in this prior art is not complete when the tube comprises more than two parts.
  • this solution requires an installation of the tube on its supports by an essentially radial movement, which is not always possible given the accessibility conditions for tree housing winding.
  • DE-B-23 26 464 teaches to mount, on a tube of monobloc winding, an axis provided with a rack tilted and locked in position by a drawer.
  • the size of the locking mechanism is such that it does not could not be used for two parts of a tube telescopic.
  • US-A-3,315,728 discloses a telescopic tube, one of which end piece has grooves of different lengths. of the safety tabs are provided to avoid a inadvertent insertion of the tip into the part main tube, these tabs do not interfere with the nozzle when it slides relative to the rest of the tube.
  • the invention relates to a tube of telescopic winding for shutter apron, door, awning or similar rolling element of an installation of closures or sun protection, this tube comprising at at least two parts capable of sliding one inside the other and means for blocking the sliding of these parts.
  • This tube is characterized in that the locking means are in solidarity or capable of being made integral of one of the these parts by allowing relative sliding of these parts in a direction of elongation of the tube and opposing relative sliding of these parts in a direction of shortening of the tube.
  • the tube can be prepared in workshop in folded configuration, i.e. with a minimum length, the locking means being fixed or mounted on one of its constituent parts and does not not likely to be lost.
  • the tube can be inserted in its box and deployed, without that it is necessary to carry out preliminary measures and without complex machining operation, this being compatible with the locking means of the invention.
  • the tube is not likely to accidentally fold since the locking means oppose sliding in one direction shortening.
  • the invention also relates to a mechanism for operation of a closing or protective installation solar which includes a winding tube such as previously described. Such a mechanism is easier to install and maintain that those of the state of the technical.
  • the tube T shown in Figures 1 and 2 includes part of inner tube 1 and part of outer tube 2 whose respective sections are as they can slide one in the other according to the direction an axis XX 'which is also the longitudinal axis of the tube T and parts 1 and 2.
  • Part 2 has four rows of openings 21. These rows of openings are arranged in grooves 22 which extend parallel to the axis XX ', so the rows of openings are also parallel to this axis.
  • the tube T allows the winding of an apron T 'of flap or its unwinding, by a rotation of parts 1 and 2 around the axis XX '.
  • the apron T ' is represented in mixed lines in Figure 2 in partially configuration wound.
  • the apron T ' is wound both on parts 1 and 2 which have similar transverse dimensions and are hollow, since they are parts of T tube.
  • part 1 has four legs elastically deformable, two of which are visible at the Figure 1 with the reference 12. These legs 12 are in one piece with part 1 which can be made of metal or material plastic. At their respective free ends 13, the legs 12 each form a bolt 14 defined essentially between two surfaces 15 and 16. Surface 15 which constitutes the end of the tab 12, is generally perpendicular to the axis XX 'in the rest configuration and in the configuration shown in Figure 2, while the surface 16 is inclined relative to this axis.
  • the four legs 12 have substantially all the same geometry and are distributed at 90 ° around the axis XX '.
  • E we denote the gap between two adjacent openings in the same row, the gap being the same for the four rows provided on the part 2.
  • the openings 21 in two adjacent rows 21, that is to say, two rows oriented substantially 90 ° relative to each other around the axis XX ′, are offset parallel to this axis by a distance d equal to about half the distance e .
  • the lugs 12 of part 1 can be engaged either in the openings 21 of the rows shown in the upper part and in the lower part of FIG. 2, or in the openings 21 of the row shown in the intermediate part of FIG. 2 and of the row which is not shown because this figure is a section.
  • the offset of the distance d allows an adjustment of the length of the tube T with a pitch p equal to half the difference e .
  • the legs 12 allow the elongation of the tube T but oppose its shortening.
  • the T tube can therefore be placed in the box a locking or sun protection installation, while its length is significantly shorter than that sought, then stretched so as to come to bear, by standard tips, on supports also provided standards in this box.
  • the geometry of the grooves 18 and 22 and the clips 3 and 3 ' can be chosen so that in the configuration of Figure 2, the clips do not protrude relative to the grooves 22 in which they are incurred.
  • the legs 12 can be attached to the part of tube 1, for example riveted or crimped.
  • these tabs can be metallic strips, for example example in spring steel, while parts 1 and 2 are made of plastic.
  • the tube T of this mode of realization is used for the selective winding of an apron T ' and includes an internal part 51 and an external part 52 intended to slide one into the other along an axis XX '. These parts are respectively provided with openings 67 and 71 arranged in rows in grooves 68 and 72.
  • a ring 54 is provided to be introduced into the end 61 of the part 51 intended to be inserted into the part 52.
  • This ring is provided with elastic hooks 91 diametrically opposite and intended to penetrate certain openings 67 after the ring 54 has was introduced into the end 61 according to a movement represented by the arrow F 5 in FIG. 3.
  • the ring 54 is made of plastic and forms four legs 62 whose respective ends 63 constitute bolts 64, each bolt being defined between a surface 65, perpendicular to the axis XX 'when the ring 54 is in place, and a surface 66 oblique to this axis.
  • the legs 62 are compatible with sliding in a direction of elongation of the tube T, as represented by the arrows F 1 in FIG. 4, and are opposed to sliding in the opposite direction, as represented by the arrows F 3 , this due to the distribution of the forces F 2 and F 4 respectively transmitted to the bolts 64 by the edges 73 of the openings 72.
  • openings 117 are arranged in rows in grooves 118 formed on the surface part 101, while openings corresponding 121 are formed in grooves 122 formed on the external part 102 of the tube T.
  • the ring 104 is designed to be inserted in the front end 111 of the part 101, as shown by the arrow F 5 .
  • the ends 113 of the legs 112 form bolts 114 defined between surfaces 115 and 116 which are respectively perpendicular to the longitudinal axis XX 'of the mounted tube, that is to say to the sliding axis of the parts 101 and 102 , and oblique to this axis.
  • locking clips similar to those, 3 and 3 ', described with reference to the first embodiment.
  • the use of locking clips is optional.
  • the tube T of this mode of realization includes an internal part 151 of which one end 161 is provided for insertion and sliding in one end 174 of an external part 152 of the tube T.
  • the tube T allows the selective winding of an apron T '.
  • Part 151 is provided with openings 167 arranged in rows in grooves 168 parallel to the axis longitudinal X-X 'of the tube T which is also the axis of relative sliding of parts 151 and 152. Openings 171 are provided in part 152 and are arranged in rows in grooves 172 also parallel to the axis XX '.
  • a blocking bar 155 is provided to be mounted on the part 152, near its end 174
  • This bar includes a first branch 162 formed of two sections 162 a and 162 b capable of pivoting relative to one another around an axis X 162 defined by a groove 162 c formed on an external face 162 d of the branch 162.
  • the branch 162 On its opposite face 162 e , the branch 162 carries two gadroons 162 f intended to penetrate into two adjacent openings 171, which used to immobilize the bar 155 on the part 152.
  • the grooves 172 have a tail shaped dovetail adapted to that of the section 162 a, so that the groove in which is engaged the section 162 is involved in the immobilization of the bar 155 of the part 152 .
  • the section 162 b of the branch 162 carries a bolt 164 defined between a surface 165, generally perpendicular to the axis XX 'in the blocked configuration of the parts 151 and 152, and a surface 166 oblique with respect to this axis in the same configuration.
  • the section 162 b can pivot around the axis X 162 , so that the bolt 164 can be selectively engaged in an opening 171 and in an opening 167 arranged opposite.
  • the part 151 of the tube is immobilized relative to the part 152 in a direction of shortening of the tube T represented by the arrows F 3 in FIG.
  • From section 162 b of branch 162 extend two secondary branches 169 and 169 ′ in directions generally parallel to the axis X 162 . These branches are articulated on the section 162 b around two axes X 169 and X 169 , perpendicular to the axis X 162 , this thanks to grooves 169 a and 169'a formed on the external face 155 a of the bar 155 which includes face 162 d .
