Definitions

  • the present invention relates to a foldable reel, in particular although not exclusively a reel intended for the winding of electric cables or optical fiber cables.
  • Foldable reels comprising cheeks associated with a drum comprising articulated elements each comprising two parts having opposite ends connected to each other and opposite ends connected to the cheeks by means of articulation formed by hinges so that the parts of the articulated elements are substantially aligned and substantially perpendicular to the cheeks for a position of use of the reel, and are folded in a direction substantially parallel to the cheeks for a storage position of the reel, the parts of the articulated elements having lateral surfaces arranged in a contiguous manner according to radial planes of the drum for a position of use of the drum.
  • Drums of this type have the advantage of having a smaller footprint in the folded position than conventional drums with a rigid drum and, in a position of use, the lateral surfaces of the parts of the articulated elements bear on each other. so that the forces resulting from the winding of the cable on the drum are regularly distributed over the lateral surfaces of the articulated elements.
  • the shocks to which the cheeks are subjected cause the hinges to deteriorate so that the foldable drum risks to be quickly out of use.
  • the simultaneous rupture of several hinges risks putting the drum immediately out of use.
  • a foldable drum of the above type comprising less a reinforcing and locking member extending axially inside the drum and ensuring an elastic connection tending to bring the cheeks towards one another.
  • the reel according to the invention comprises two cheeks 1 which support a drum generally designated at 2.
  • the drum 2 comprises articulated elements 3 each comprising two parts 4 in the form of bars. Two parts 4 of the same articulated element 3 are connected together in an articulated manner in the manner of a compass by an articulation means comprising elastic members 5 fixed at the ends opposite two associated parts 4. The opposite end of the parts 4 is connected to the cheeks 1 by articulation means comprising elastic members 6.
  • the elastic members 5 and 6 are rubber or elastomer pads each comprising an elongated central body 7 and two hemispherical bearing heads 8 produced in one piece with the central body 7, the flat parts hemispherical heads being turned towards the central cylindrical body 7.
  • the parts 4 are hollow and have an outer wall in cylinder portion 9, end walls 10 perpendicular to a longitudinal direction of the parts 4 and side walls 11 arranged in corresponding planes to radial planes of the drum when the latter is in the position of use.
  • the end walls 10 of the parts 4 and the cheeks 1 have through orifices 12 (FIG.
  • the cylindrical body 7 of the rubber studs has, at rest, a length l slightly less than the thickness E of two associated walls so that the cylindrical body 7 is in tension even when two associated parts 4 are aligned as illustrated in FIG. 3, so that the end faces of the parts 4 are pressed against the facing surface and ensure the stability of the articulated members 3 when the reel is in the position of use.
  • the cheeks 1 further comprise crowns 13 projecting towards the inside of the drum and the parts 4 comprise positioning lugs 14 which extend into an orifice 15 of the associated wall for a position use of the drum.
  • the protruding crowns 13 are arranged so that the ends of the parts 4 adjacent to the cheeks are arranged to bear on these crowns for a position of use of the reel. In this position, the side walls 11 of the parts 4 bear on each other so that all of the parts 4 form a vault forming the drum 2 which rests on the projecting crowns 13 thus preventing the drum 2 from sliding. relative to the cheeks 1 in a direction parallel to the cheeks 1. On their sides the positioning pins 14 which cooperate with the cheeks 1 prevent sliding of the drum 2 with respect to the cheeks 1 in a tangential direction of the drum 2 so that the this avoids subjecting the elastic members 6 to shearing forces both radially and in a direction tangential to the drum 2.
  • the reel When a cable is wound on the drum 2, the reel therefore forms a rigid assembly adapted to support the weight of the cable and if the reel cheeks receive a shock, the deformation of the reel is absorbed by the elastic members without damaging them and the tension of the elastic members s which results from this deformation tends to bring the cheeks in support on the end faces of the drum 2.
  • the flexibility of the elastic members makes it possible to slightly push one of the articulated elements 3, which makes the immediately adjacent articulated elements protrude outwards and makes it possible to grasp the 'one of them and pull it outward as illustrated in Figure 4.
  • the outer edge 16 of the ends of the parts 4 adjacent to the cheeks rests on the cheek 1 while the inner edge 17 is supported on the crown 13 and the inner edges 18 of the ends of two opposite parts 4 are supported one on the other to allow pivoting of the parts 4 until they reach a storage position where they extend in a direction parallel to the cheeks.
  • the central part of the elastic members extends parallel to the end wall of the corresponding part 4 and exerts on it a force which tends to press the part 4 against the cheek 1.
  • the reel is thus metastably maintained in the storage position. To return it to the position of use, it is sufficient to separate the cheeks 1 until the parts 4 switch of their own accord to the position of use.
  • FIG. 6 illustrates another embodiment in which the elastic members 5 and 6 comprise rubber bracelets.
  • the end walls 10 of the parts 4 have notches 19.
  • the rubber bracelets 5 which join two opposite ends of the parts 4 are engaged in the notches 19 while keeping the bracelets in a form annular while the bracelets 6 ensuring the connection between one end of a part 4 and a cheek 1 are folded back on themselves, the two adjoining strands being engaged in the notches 19 of a part 4 while the loop-shaped ends 20 thus produced are engaged in openings 21 of the cheeks 1 and are retained on the outside of the cheeks 1 for example by means of a rod engaged in the loops 20 or by providing on the cheeks 1 of the lugs projecting outwards on which the loops 20 are engaged.
  • the drum comprises reinforcing and locking members extending axially inside the drum and ensuring an elastic connection tending to bring the cheeks towards one another.
  • the reinforcing and locking members comprise steel cables 22 disposed axially inside the drum 2 and equipped with support pieces 23 which are supported on annular pads 24 of rubber or elastomer disposed in cavities 25 provided in the cheeks 1.
  • the annular pads 24 have a diameter greater than the support pieces 23.
  • the length of the cables 22 is provided so that in the position of use of the reel the elastic buffers 24 are compressed by the support pieces 23 and thus ensure a tension of the cable 22 which tends to bring the cheeks 1 towards one another. 'other and therefore to maintain these strongly applied to the corresponding ends of the parts 4.
  • a shock for example when the reel falls askew from a transport vehicle or from a quay, this shock tends to spread one of the cheeks of the corresponding end of the drum 2, which causes increased tension on the cable 22.
  • This increased tension is absorbed by the elastic pads 24 which tend to bring the cheek 1 towards its support position on the end of the drum and absorb part of the impact energy so that this energy is not entirely transmitted to the elastic members 6.
  • the cavity 25 has an internal diameter substantially equal to the external diameter of the elastic pad 24 and the bottom of the cavity 25 has an opening 26 having a size close to or greater than the dimension of the head 23 so that the pad 24 can momentarily flow through the opening 26, which minimizes the tensile stress to which the cable 22 is subjected.
  • FIG. 9 illustrates another embodiment of this aspect of the invention in which the reinforcing and locking members simultaneously perform the function of articulation means between the parts 4 and the cheeks 1.
  • the reinforcing and locking member is constituted by a cable having a longitudinal elasticity, for example a textile cable 27 which extends through the cheeks 1 and is folded over an annular bead 28 and again passes through the cheeks 1 and through the end wall of the parts 4, the ends of the cable 27 being fixed by heads 29.
  • the heads 29 are for example produced by making knots at the ends of the cable 27 or by bringing the heads 29 by crimping at the ends of the cable 27.
  • a shock on the cheeks which tends to bring them together causes the articulated elements 3 to bend inwards until the opposite ends of the parts 4 bear on the cable 27 which thus limits the deformation articulated elements while ensuring their elastic return to a normal position of use.
  • the first embodiment of the reinforcing and locking member has been illustrated in the form of a single cable disposed along the axis of the reel, one can provide several reinforcing and locking cables distributed evenly around the axis of the reel. In the embodiment of FIG. 9, it is of course necessary to provide as many cables 27 as articulated elements 3 constituting the drum 2.
  • an elastic pad may be provided in any other material, for example in knitted steel wire and compressed, provision can also be made to fix the ends of the cable 22 to elastic discs, for example in the center of the spring steel discs having an outer edge embedded in the cheeks 1.
  • articulation means comprising elastic members
  • articulation means comprising hinges
