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 together and opposite ends connected to the cheeks by articulation means formed by hinges arranged so that the parts 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 so contiguous along radial planes of the drum for a position in which the drum is used.
  • 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 reel of the type mentioned above is proposed according to the invention.
  • which the parts of the articulated elements have end faces substantially perpendicular to a longitudinal direction of these parts, and the articulation means comprise elastic members.
  • the end faces of the articulated elements bear on the cheeks and are pressed against them by the elastic members so that these ensure both stable positioning of the articulated elements, a possibility of folding them and resistance to impact on the cheeks by an elastic deformation of the elastic members.
  • the elastic members are under tension for a position in which the reel is used.
  • the stability of maintaining the reel in a position of use is increased, in particular at the start of the cable winding operation, thus avoiding untimely folding of the reel.
  • the cheeks have crowns projecting towards the inside of the drum and the ends of the parts of articulated members adjacent to the cheeks are arranged to bear on these crowns.
  • the shearing force to which the elastic members are subjected is minimized.
  • the drum comprises at least one reinforcing and locking member extending axially inside the drum and ensuring an elastic connection tending to bring the cheeks towards one another for a position in which the drum is used.
  • the force pressing the cheeks on the ends of the articulated elements ensures increased locking of the drum in the position of use and minimizes the shearing force to which the elastic members are subjected.
  • 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 interconnected in an articulated manner like a compass by a means articulation 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 cylindrical central 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 passage orifices 12 (FIG.
  • the cylindrical body 7 of the rubber studs has, at rest, a length 1 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 provide stability for 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 lugs positioning 14 which extend into an orifice 15 of the associated wall for a position of 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 lugs 14 which cooperate with the cheeks 1 prevent sliding of the drum 2 relative 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 to bear 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 projects the immediately adjacent articulated elements outwards and makes it possible to grasp the 'one of them and pull it outwards 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 internal edges 18 of the ends of two opposite parts 4 are supported one on the other to allow the parts 4 to pivot 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 holding the bracelets under a annular shape 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 joined strands being engaged in the notches 19 of a part 4 while the ends in shape of loops 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 lugs projecting towards the outside 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 bear on annular pads 24 made of rubber or elastomer arranged 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 dimension close to or greater than the dimension of the head 23 so that the plug 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 passes again 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 invention has been described by providing that the elastic members 6 forming the articulation means are preferably in tension when the reel is in a position of use, provision can be made, when the reel is equipped with '' reinforcing and locking members, to adopt for the elastic members forming the articulation means, a dimension eliminating the constraints for a position of use of the reel so as to stress the elastic members forming the articulation means only when the reel is in the storage position.
  • the first embodiment of the reinforcing and locking member has been illustrated in the form of a single cable arranged along the axis of the drum, it is possible to provide several reinforcement and locking cables distributed evenly around the axis of the drum.
  • an elastic pad may be provided in any other material, for example in knitted and compressed steel wire. Provision may also be made to fix the ends of the cable 22 to elastic discs, for example at the center of spring steel discs having an outer edge embedded in the cheeks 1.
  • the support heads can be attached to the central body, for example by crimping the support heads 8.
  • the elastic members have been described with a cylindrical central body 7, these elastic members can also be produced in the form of tongues having a beveled end comprising a shoulder turned towards the central part so as to be force-fitted into slots provided in the end walls of parts 4.
