Definitions

  • the present invention relates to a device for unfolding and folding over itself a threadlike link, to which is linked at least one vertical extension part.
  • readlike link any elongated element, of the wire, ribbon, strap or border type, etc., having a relative flexibility or suppleness depending on its length, which makes it possible to pick up its linear size by folding back on it -same, for example according to a zig-zag conformation.
  • Very extension piece means any element extending vertically downwards, linked in one way or another to the filiform link, for example suspended from the latter, in one or more places regularly distributed according to the length of the threadlike link.
  • This piece can be an isolated element falling downwards, as it can be a flexible continuous wall of horizontal extension, of the fabric, fabric, curtain, panel or sheet type, capable of being picked up on itself by folding.
  • the filiform link previously introduced consists of the upper edge of said curtain, for example folded and sewn on itself, or in an attached ribbon or strap, for example by sewing, on the upper edge of the curtain.
  • the vertical extension piece, also introduced previously, in this case consists of the curtain itself.
  • a device as previously described has the following drawbacks.
  • the present invention relates to a solution making it possible to distribute the displacement effort of the curtain, over its entire upper edge, both at opening and at closing the curtain.
  • each of these is found to be driven, like the conductive trolley, by the draw loop, both in the direction of unfolding and in the direction of folding back , for example both in the closing direction and the opening of the curtain.
  • each carriage is pulled by the motor strand of the pulling loop, and not by the curtain itself.
  • the present invention further provides the following critical advantages.
  • the filiform link in this case the upper edge of the curtain, being driven at points regularly distributed along its length, it becomes possible to produce devices with guide rail curve. These convex or concave zones can be passed without difficulty by each suspension trolley.
  • a device according to the invention for opening and closing a stage curtain for example, is arranged or fixed, in a manner not shown, between two vertical walls 24 and 25. This device ensures the opening and closing of a curtain 2, in a bay between two front panels 26 and 27.
  • the guide rail 3 comprises a single slide 4 for the movement of the carriages 5, comprising as previously a displacement section 4a of the curtain, when unfolded or unfolded, and a storage section 4b of the same curtain, when folded or folded.
  • the same rail 3 comprises a slide 13 for holding or guiding the pulling loop 10, arranged sensibly at right angles to the circulation slide 4.
  • the latter comprises two raceways 4a and 4b, arranged the one above the other, and directed in opposite cross-section; each raceway 4a or 4b, of "U" cross section has a strip or lining of elastic material 46, arranged on its bottom, and capable of damping the noise generated by the movement of the carriages 5.
  • the circulation slide 4 and the slide 13 for holding or guiding the strip 10 are in fact two sections respectively, assembled relative to each other at right angles. More specifically, the guide rail 3 is obtained by assembling modular sections 4, differentiated for the purposes of the description according to 41 and 42, and modular sections 13, also differentiated for the same purpose according to references 131 and 132.
  • a section 4 has a hollow core, determining on both sides the two raceways 4a and 4b with a cross section in "U" shape, a collar 4e being provided on the inner side of said profile.
  • Each retaining profile 13 has a hollowed-out central core opening to the outside. On either side of this core are respectively provided a male stud 13a for attachment, and a female groove 13b also for attachment. On either side of the profile 13, between the stud 13a and the groove 13b, two notches facing each other are formed, each forming a guide path and holding the pulling loop 10.
  • the guide rail is obtained accordingly by assembling the two retaining sections 131 and 132, by clipping the stud of one into the groove of the other, by providing between them two interstices 19, in which are inserted and locked respectively.
  • the sections 132 and 42 have no role with respect to the device according to the invention, except to ensure and complete the assembly by clipping of the guide rail 3.
  • Such an embodiment of the guide rail makes it possible to obtain slides for circulation and for maintaining the pulling loop, which are much more precise. It is also much easier to make connections, securely, between different elements of a rail thus produced. Furthermore, when the pulling loop is traditionally constituted by a cord, the latter can be taken over its entire length in the recess of the retaining profile 13, which allows! And to ensure good guidance, including when the rail 3 is bent.
  • Each suspension carriage 5 comprises three rolling rollers 6, 7 and 8, arranged in an equilateral triangle, and mounted by means of ball bearings on a spacer 20 external to the guide rail 3, having a planar shape in an equilateral triangle. Consequently, each carriage comprises, on one side two rollers, for example 6 and 7 for the carriage 50, located at the same level, and a roller, for example 8, located below, the height gap separating these two rolling levels being equal to the distance between the two rolling paths 4c and 4d.
  • Each suspension carriage 5 comprising, at its lower part, a hooking means or ring 9, is mounted on the guide rail 3, so as to grip the circulation slide 4.
  • two rollers for example 6 and 7 for the carriage 50, are arranged in the path upper bearing 4c, and the other roller, for example 8 for the carriage 50, is arranged in the other lower rolling path 4d. This gives mechanical and precise guidance, without pendulum movement, of each suspension carriage 5.
  • the different carriages 5 are also differentiated from each other, according to the relative position of the hook 9.
  • the hook 9 is integral with the spacer 20, below a roller 8; for the carriages 51 and 53, the hook 9 is secured to a straight edge of the spacer 20 between two rollers 6 and 7.
  • This makes it possible to arrange the different carriages 5 in relative position "spade head", relative to the other.
  • One thus obtains an interpenetration of the suspending carriages 5, contiguous in the massage section 4b, as shown in FIG. 5. In total, one can thus bring the hooking hooks 9 closer to one another, and thus limit the length of the massage section 4b, for the same curtain.
  • the hooks 9 serve for the suspension or connection with a ribbon 1, attached, for example by sewing on the upper edge of a curtain 2, which is then suspended by the ribbon 1.
  • One of the suspension carriages 5, namely the carriage 50, is permanently coupled to the pulling strip 10, including in its massage position according to Figure 1, so that it plays the role of a conductive carriage. All the other carriages 5, for example 51, 52, 53 and 54, are hooked reversibly on the strip 10 by the general means described above, so that they play the role of driven carriages.
  • each carriage 50 is obtained in the following manner.
  • the internal end 14a of the axis 14 projects from the suspending carriage 5, in the direction of the pulling strip 10, and forms a latching pin.
  • the other end 14b of the same axis 14 is returned to the pulling strip 10, by a return means 18 fixed on the carriage in question.
  • This return means consists of an elastic metal blade, one end of which is fixed to the spacer 20, and the other end of which is secured to the external end 14b of the axis 14.
  • the suspending carriage considered, for example the carriage 54 is mounted on the circulation profile, in the manner already described with reference to FIG. 4, and comprises a hanger 30, for a driven mechanism 21, in this case a reel 23 of winding / unwinding a wire 24 for lifting the suspended curtain 2.
  • the mechanism 21, which acts on the part of the curtain 2 locally suspended from the carriage 54, is coupled to the control loop 22, by means of teeth 23a meshing with perforations 22a of the strip 22.
  • the control loop 22 passes at least in part over pulleys supported in rotation by the guide rail 3.
  • the present invention can be applied in many other technical fields than that of curtains, for example in the field of decoration, display, etc.
