This provision is of a more robust constitution, although it is adapted to crowns of cables of dimension and weight relatively small

In effect, the reel rolls on the rollers that support the total weight of the crown and the reel. Yes this weight it is relatively important, the rollers are subjected to a important effort that causes rapid wear and phenomena friction and blocking make this provision little effective.

In addition, the reel equipped with a crown must be carried and lifted for placement in the support of winding, which is not easy in the case of weight and dimension relatively important.

Patent document US 5,934,314 explains a winding device having a reel consisting of a drum and two side discs and a reel holder on which the latter is mounted with freedom of rotation, having this support two rigidly joined side walls.

The reel is equipped with a crossbar constituted by two arms connected to the drum, with freedom of rotation along its longitudinal axis and joined by a crossbar of grip, and the side walls of the bracket have provisions of support and blocking of this stringer.

The object of the invention is to propose such cable winding device, particularly cables electrical, ensuring for any dimension of the crown a perfect stability of the winding support equipped with a reel and a cable crown, an effective support with freedom of rotation of the reel in the support and, in addition, to facilitate the Reel placement on the winding support.

To achieve this the invention proposes a winding device having a reel consisting of a drum and by two lateral discs and a reel holder on the which one is mounted with freedom of rotation, having this support two side walls rigidly joined by at least two crossbars arranged in the vicinity of two of its corners, said reel being equipped with a stringer constituted  by two arms connected to said drum, with freedom of rotation along its longitudinal axis and joined by a crossbar of holding and having said side walls of the support support and blocking provisions of this crossbar, characterized in that said blocking arrangements ensure the blocking of said crossbar of crossbar tension in said side walls of the support, so that this bar cross section constitutes a crossbar Supplementary solidarity of each of its walls in the vicinity from a corner of its walls.

According to a preferred embodiment of the invention said two side walls are substantially rectangular  or square, and said union of the two side walls has three solidarity crossbars of each of its walls in the proximity of three of its corners.

Preferably, each arm of said stringer it has at its end a bolt that is embedded in a bore side of the drum

Very advantageously, said locking arrangements ensure the blocking of said crossbar of the stringer clamp on said lateral walls of the support, so that this clamping transverse bar constitutes a fourth integral crossbar of each of its walls in the vicinity of a corner of their parents
des.

Preferably, said blocking arrangement has for each side wall associated with each arm on the one hand a means of blocking the rotation of the arm around the axis of rotation of the reel, and on the other hand a means of translation lock longitudinal arm.

Said turning lock means may be constituted by a fixing tab by clip carried by each side wall of the support against which it stops butt locked a side flange that carries the stringer arm correspondent.

Said translation blocking means may be constituted by a series of parallel grooves on the face internal of each wall in which a series of ribs fits arranged on the outer face of each arm of the crossbar.

Preferably, said provisions of support ensure the support of each of said arms  of the stringer in the vicinity of the center of each of said side walls.

On the face turned outward, the end free of each arm can carry a radial and circular flange that cooperates with a partial circular groove arranged in the wall corresponding to the support and that constitutes said provision of sustenance.

At least one of the two lateral discs can be mobile and adjustable in position on the drum.

The following describes in detail the invention with the help of figures that represent only one way preferred embodiment of the invention.

Figure 2 is a partial view in section and in perspective of a reel, part of a winding device of according to the invention.

Figure 3 is a perspective view of a winding device according to the invention.

Figures 4 and 5 are sectional views. transverse in a plane perpendicular to the axis of the drum.

Figure 6 is a horizontal section view corresponding to figure 4, according to a plane passing through the axis of symmetry of the drum 1A.

Figure 7 is a detailed sectional view of Figure 6

Figure 8 is a detailed sectional view of Figure 5

The reel shown in figure 1 can be a spool of the type described in the FR patent application 2,886,930.

This reel 1 of plastic material is composed of a drum 1A and two discs 1B, 1C mounted jointly. A 1B disk has a mounting arrangement for a transport handle 1D of the reel, being this articulated handle in a circular disc groove and pivoting in a first sense in which it completely fits into the slot, in a position called use, and in another sense in which it stops at a groove in the groove, in a position called storage. This 1D grip is here represented in deployed reel transport position.

In order to adapt the reel to crowns of cables of different axial lengths, at least one of the Side discs are adjustable in position on drum 1A. For obtain this adjustment, the outer surface of the drum has a filleting on which a tooth is guided preferably constituted by sections of teeth distributed on the periphery of the central boring of the disk in question. Thus, through a Screwing the disc into the drum can be adjusted separation between the two discs 1B, 1C on the axial length of the crown of cable to be placed.

The disk is therefore disassembled, the crown of cable inserted into the drum, then the disc is reassembled and adjust in the correct position.

According to the invention, reel 1 is associated with a stringer 2 as illustrated in figure 2, in which the disks They are not represented.

The reel is equipped with a stringer 2 consisting of two arms 2A, 2B, preferably of material plastic, connected to drum 1A, with freedom of rotation along its axis longitudinal and joined by a 2C clamping crossbar, preferably metallic.

Disks not shown here are placed on peripheral filleting of drum 1A.

The placement of the crossbar 2 is done by deformation by separating these arms 2A, 2B and fitting a 2D bolt carried by the end of each arm 2A, 2B which is housed in a central and lateral boring of the drum.

Although not illustrated, the assembly of the stringer 2 is made once the cable crown is placed on the reel. In this position the crossbar can allow transport of the reel loaded, by pressing the bar 2C cross section.

The winding device according to the invention also has a reel holder 3, represented in Figure 3, in which the reel 1, here not loaded with a crown cable, is mounted with freedom of rotation.

This support 3 has two side walls 3A, 3B preferably of plastic material, substantially rectangular or squares rigidly joined by means of three bars transverse T 1, T 2, T 3, preferably metallic, solidarity of each of its walls in the proximity of three of Its corners

These side walls of the stand 3A, 3B they have support and support arrangements for the stringer 2.

These blocking arrangements ensure the locking of the crossbar of tension 2C of the crossbar in the side walls 3A, 3B, of the support, so that this bar cross section constitutes a fourth crossbar solidarity of each of its walls in the proximity of one of its corners

These support provisions ensure the holding of each of the arms 2A, 2B of the crossbar in the proximity of the center of each of the side walls 3A, 3B.

These provisions of support and of blocking will be specified by means of figures 4 to 7.

Figures 4 and 5 are sectional views. vertical transverse in a plane perpendicular to the axis of the drum, only one disc and the stringer being visible. Figure 6 is a horizontal section view corresponding to figure 4, according to a plane that passes through the axis of symmetry of the drum 1A.

The crossbar is mainly held in position in the proximity of the center of each of the walls sides 3A, 3B, thanks to a support means arranged in each disc and that cooperates with a complementary medium carried by the end of each arm 2A, 2B opposite the end connected to the bar 2C cross section.

These media are represented in detail in Figure 7

As already seen, and as equally illustrated in figure 2, each arm 2A, 2B presents at its end a 2D bolt that is embedded in a central side bore of the drum 1A, and that ensures the union of the stringer 2 in this latest.

On its face turned outwards this end each arm has a radial and circular flange B, complete or partial, whose central axis is the axis of symmetry of the 2D bolt. This radial flange is inserted into a partial circular groove R arranged in the corresponding wall 3A of the support, which is open to allow the introduction of flange B, as is especially visible in figure 4, in which the arm is in insertion position in the corresponding slot. Each arm 2A, 2B is thus held with freedom of rotation in each side wall 3A, 3B of the winding support.

By the displacement of the crossbar of 2C clamp down and the corresponding turn of flange B in the groove R, the stringer is then moved to the position illustrated in figure 5.

Each arm 2A, 2B is then blocked by the locking arrangements carried on each side wall 3A, 3B of the winding support. This blocking provision has for each side wall 3A, 3B associated with each arm 2A, 2B, on the one hand a arm rotation lock means around the axis of rotation of the reel, and on the other hand a means of translation lock longitudinal arm.

The turning lock means is constituted by a fixing tab by clip L that has each wall side 3A, 3B of the support against which it stops butt a lateral flange D having the arm 2A, 2B of the crossbar correspondent.

The translation blocking means is consisting of a series of parallel S slots carried by the inner face of each wall 3A, 3B in which a series is fitted of ribs N arranged on the outer face of each arm 2A, 2B of the crossbar.

Thus held and locked, each arm 2A, 2B of the stringer is solidly integral with each side wall 3A, 3B of the winding support, and the 2C clamping crossbar of the stringer forms a fourth crossbar of support reinforcement winding The drum 1A provided with these two discs 1C, 1D, in as for him, he is free to turn on the crossbar, in order to allow winding of the cable crown.

To normalize the molding of the walls sides 3A, 3B of the winding support, the latter are designed symmetrically with respect to a horizontal plane, as seen in the figures.

Several winding brackets can be overlays as illustrated in figure 5.

To do this, the side walls 3A, 3B of the winding support are provided with a ratchet C in the proximity of each of its corners, and each wall 3A, 3B has two A fixings made by molding with the wall and held by cuttable tabs.

When you want to superimpose two supports of wound the four fasteners A of the two walls 3A, 3B of the lower support are released from the walls and snagged on the four corresponding C ratchets, that is, higher for the lower and lower support for the upper support. This fixing ratchet arrangement is illustrated in detail in Figure 8
