Description

L'invention s'inscrit dans le domaine de la manutention, et plus particulièrement de la manutention d'éléments discrets du type armatures métalliques, fers, fers crossés, et autres éléments, notamment susceptibles d'être mis en oeuvre dans le cadre du bâtiment.The invention is part of the field of handling, and more particularly the handling of discrete elements of the type of metal frames, irons, crossed irons, and other elements, in particular likely to be implemented in the context of the building .

Par éléments discrets, on entend des produits autres que le vrac.By discrete elements are meant products other than bulk.

ETAT ANTERIEUR DE LA TECHNIQUEPRIOR STATE OF THE TECHNIQUE

Les sacs de manutention de grande capacité sont aujourd'hui d'un usage largement répandu, qu'il s'agisse du stockage et du transfert de matériaux en vrac, ou d'éléments discrets du type de ceux rappelés en préambule.The large-capacity handling bags are now widely used, whether storage and transfer of bulk materials, or discrete elements of the type recalled in the preamble.

Ils sont généralement constitués d'une enveloppe en textile synthétique, notamment tissée, comprenant un fond et une paroi latérale, ladite enveloppe étant munie de moyens d'accrochage à notamment un engin de levage, ces moyens d'accrochage étant en général constitués d'une sangle ou d'une pluralité de sangles solidarisées à l'enveloppe.They generally consist of a synthetic textile envelope, in particular woven, comprising a bottom and a side wall, said envelope being provided with attachment means including a hoist, these attachment means being generally constituted of a strap or a plurality of straps secured to the envelope.

Ces sacs, bien connus dans le domaine sous l'expression « big bag », sont réalisés en général en polypropylène, et sur lequels sont solidarisées, notamment par couture, des sangles définissant une ou plusieurs anses de préhension par un engin de levage permettant ainsi de les manutentionner.These bags, well known in the field under the term "big bag", are generally made of polypropylene, and on which are secured, in particular by stitching, straps defining one or more gripping loops by a hoist thus allowing to handle them.

Le document DE 8 336 862 U1 divulgue un sac de manutention.The document DE 8,336,862 U1 discloses a handling bag.

L'une des difficultés rencontrées avec ces sacs de l'art antérieur réside dans le fait, lorsqu'ils sont utilisés pour le transport d'éléments discrets type armatures métalliques fers ou fers crossés, que l'extrémité notamment inférieure voire supérieure de ces éléments vient en contact avec les parois latérales ou le fond du sac et sont susceptibles très rapidement de les percer en raison des frottements opérés lors desdites opérations de transport, rendant lesdits sacs impropres à leur destination, et susceptibles de constituer un danger pour le personnel travaillant à proximité lors de leur manipulation, danger né notamment du risque de chute, voire de déchirement complet du sac, susceptible de se traduire par la chute des éléments qu'ils contiennent.One of the difficulties encountered with these bags of the prior art lies in the fact, when they are used for the transport of discrete elements such as metal reinforcing irons or crossed irons, that the particular lower or higher end of these elements comes into contact with the side walls or the bottom of the bag and is very likely to pierce them because of the friction made during said transport operations, making said bags unsuitable for their destination, and likely to constitute a danger to the personnel working to proximity when handling, danger born in particular the risk of falling, or even complete tearing of the bag, likely to result in the fall of the elements they contain.

Dans la construction en béton, il est connu de renforcer des éléments de construction comme des poutres ou des planchers en utilisant des fers assemblés ou non. Particulièrement, on sait réaliser par cintrage des fers constitués essentiellement par une tige d'acier de fort diamètre, seule ou assemblée à d'autres tiges semblables, et dont les deux extrémités sont repliées en crosse. Un tel fer est dit fer crossé. Il est formé dans un atelier et apporté par camions sur le chantier de construction. Il est alors déchargé du camion en attendant qu'il soit à la demande transféré de son lieu de stockage sur le lieu de montage. A cet effet, on utilise une grue de chantier pour emporter ce genre de composant de construction, par exemple pour l'emporter du lieu de déchargement où il est stocké, vers le lieu où il va être installé dans un coffrage, avant d'être soudé sur son armature finale et noyé dans une coulée de béton.In the concrete construction, it is known to reinforce construction elements such as beams or floors by using irons assembled or not. In particular, it is known to achieve by bending irons consisting essentially of a steel rod of large diameter, alone or assembled with other similar rods, and both ends are folded into a stick. Such an iron is said cross iron. He is trained in a workshop and brought by trucks to the construction site. He is then unloaded from the truck until he is at the request transferred from his place of storage to the place of assembly. For this purpose, a construction crane is used to carry this kind of construction component, for example to take it from the unloading place where it is stored, to the place where it will be installed in a formwork, before being welded on its final frame and embedded in a concrete pour.

Pour exécuter le transfert du lieu de stockage au lieu de montage, le fer crossé est chargé dans un sac de manutention, du type « big bag ». Comme indiqué précédemment, les sacs de manutention de ce genre sont rapidement percés dans une région proche du centre de leur fond, parce que le frottement opéré par la crosse des fers qui y sont chargés réalise un enlèvement de matière et, à terme, le perçage du sac. Ce dernier doit être éliminé avant de présenter un danger de perte de la charge dans le sac percé lorsque la grue a emporté en hauteur sa charge.To carry out the transfer from the storage place to the mounting location, the cross-lapped iron is loaded into a big bag. As indicated above, such bags are quickly drilled in a region close to the center of their bottom, because the friction operated by the butt of the irons loaded therein carries out a removal of material and, eventually, piercing of the bag. The latter must be eliminated before presenting a danger of loss of the load in the pierced bag when the crane has carried off its load.

L'objet de la présente invention est donc de surmonter ces inconvénients.The object of the present invention is therefore to overcome these disadvantages.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

Ainsi, l'invention vise un sac de manutention qui comporte :

  • des moyens d'accrochage du sac à un engin de levage ;
  • une enveloppe réalisée en textile synthétique tissé présentant une ouverture supérieure, un fond et des parois latérales, et destinée à constituer le réceptacle de produits ou d'articles à manutentionner ;
Thus, the invention relates to a handling bag which comprises:
  • means for attaching the bag to a hoist;
  • an envelope made of woven synthetic textile having an upper opening, a bottom and side walls, and intended to constitute the receptacle for products or articles to be handled;

Selon l'invention, les moyens d'accrochage comportent au moins une sangle passant sous le fond du sac et qui est solidarisée d'au moins une partie du sac éloignée de son fond et libre du fond du sac, au moins une extrémité de la sangle étant destinée à former ou coopérer avec un moyen d'accrochage du sac à un engin de levage.According to the invention, the attachment means comprise at least one strap passing under the bottom of the bag and which is secured to at least a portion of the bag remote from its bottom and free from the bottom of the bag, at least one end of the strap being intended to form or cooperate with a means for attaching the bag to a hoist.

Ainsi, en ne solidarisant pas les moyens d'accrochage, en l'espèce constitués par des sangles, au fond du sac, ledit fond est libre desdits moyens d'accrochage. Ce faisant, les extrémités inférieures des éléments discrets susceptibles d'être manutentionnées par le biais du sac, et notamment des fers, armatures métallique et autres, ne viennent pas en butée sur le tissu constitutif du fond au voisinage du milieu dudit fond, c'est-à-dire en un point sensiblement unique et répétitif, mais en tous points d'un secteur latéral dudit fond, en fonction de la position du sac, diminuant de fait les frottements en un lieu systématiquement identique, et optimisant de fait la durée de vie d'un tel sac.Thus, by not securing the attachment means, in this case constituted by straps at the bottom of the bag, said bottom is free of said attachment means. In doing so, the lower ends of the discrete elements that can be handled by means of the bag, and in particular irons, metal frames and the like, do not come into abutment on the fabric constituting the bottom in the vicinity of the middle of said bottom; that is to say at a substantially unique and repetitive point, but in all points of a lateral sector of said bottom, depending on the position of the bag, thereby decreasing the friction in a systematically identical place, and thus optimizing the duration of such a bag.

Selon d'autres caractéristiques de l'invention :

  • les moyens d'accrochage du sac à un engin de levage comportent au moins deux sangles croisées sous le fond et qui restent libres sous la zone de fond et solidarisées d'au moins une partie du sac éloignée de son fond ;
  • les sangles portent un code d'identification à distance permettant notamment de reconnaître à distance notamment le contenu du sac de manutention et/ou la destination du sac de manutention ;
  • le code d'identification est constitué par la couleur ou la teinte d'au moins une sangle dudit moyen d'accrochage.
According to other features of the invention:
  • the hooking means of the bag to a hoist comprises at least two straps crossed under the bottom and which remain free under the bottom zone and secured to at least a portion of the bag remote from its bottom;
  • the straps carry a remote identification code making it possible in particular to recognize at a distance in particular the contents of the handling bag and / or the destination of the handling bag;
  • the identification code is constituted by the color or the hue of at least one strap of said attachment means.

Selon encore d'autres caractéristiques de l'invention, la ou les parois latérales de l'enveloppe sont constituées d'une double peau, c'est-à-dire de deux enveloppes, respectivement externe et interne, définissant entre elles un volume au sein duquel est insérée une plaque, notamment rigide.According to still other characteristics of the invention, the lateral wall or walls of the envelope consist of a double skin, that is to say two envelopes, respectively external and internal, defining between them a volume at within which is inserted a plate, in particular rigid.

Ce faisant, on optimise la résistance des parois latérales du sac contre les phénomènes d'usure inhérents aux frottements nés des produits ou articles reçus dans l'enveloppe du sac, par d'une part la mise en oeuvre d'une double peau, toujours réalisée en matériau synthétique, et d'autre part, par l'insertion dans l'espace qu'elles définissent entre elles d'une plaque rigide, propre à s'opposer audit phénomène d'usure.In doing so, the strength of the side walls of the bag is optimized against the phenomena of wear inherent to the friction produced by the products or articles received in the envelope of the bag, on the one hand the implementation of a double skin, always made of synthetic material, and secondly, by insertion into the space they define between them a rigid plate, adapted to oppose said wear phenomenon.

Selon l'invention, ces plaques rigides peuvent être réalisées en acier, en matière plastique, avantageusement renforcée, voire en bois ou en carton, et de manière générale, en tout matériau alliant à la fois rigidité et légèreté.According to the invention, these rigid plates can be made of steel, plastic, advantageously reinforced, or even wood or cardboard, and generally, any material combining both rigidity and lightness.

Selon une caractéristique de l'invention, ces plaques rigides peuvent être fixées à demeure au sein de la double peau constitutive de la ou des parois latérales de l'enveloppe. Dans cette configuration, les extrémités supérieures ou bords supérieurs desdites peaux sont solidarisées définitivement l'une à l'autre après, bien évidemment, insertion des plaques rigides au sein du volume qu'elles définissent entre elles. Cette solidarisation peut notamment résulter de couture.According to one characteristic of the invention, these rigid plates can be fixed permanently within the double skin constituting the side wall or walls of the envelope. In this configuration, the upper ends or upper edges of said skins are permanently attached to one another after, obviously, insertion of rigid plates within the volume they define between them. This joining can in particular result from sewing.

Selon une autre variante de l'invention, les plaques rigides sont amovibles, et donc susceptible d'être retirées de l'espace défini par les double- peaux. Cette configuration peut s'avérer avantageuse pour permettre de réduire l'encombrement généré par les sacs, lorsque ceux-ci ne sont pas utilisés. En effet, les sacs peuvent être aisément pliés. Dans cette configuration, les bords supérieurs libres des deux peaux sont réversiblement solidarisables l'un à l'autre, par exemple au moyen d'organes type boucles et crochets (mieux connus sous la marque déposée Velcro®).According to another variant of the invention, the rigid plates are removable, and therefore can be removed from the space defined by the double-skin. This configuration can be advantageous to reduce the space generated by the bags, when they are not used. Indeed, the bags can be easily folded. In this configuration, the free upper edges of the two skins are reversibly bondable to each other, for example by means of loop-type members and hooks (better known under the trademark Velcro ® ).

Selon encore une autre caractéristique de l'invention, le fond de l'enveloppe peut également comporter une plaque rigide. Celle-ci peut être simplement positionnée sur le fond textile de l'enveloppe, de sorte qu'elle peut tout aussi facilement être escamotée hors de l'enveloppe pour des besoins de stockage. Cette plaque est également destinée en coopération avec la caractéristique visée en préambule à optimiser la résistance du fond aux phénomènes d'usure.According to yet another characteristic of the invention, the bottom of the envelope may also comprise a rigid plate. This can be simply positioned on the textile bottom of the envelope, so that it can just as easily be retracted out of the envelope for storage purposes. This plate is also intended in cooperation with the characteristic referred to in the preamble to optimize the resistance of the bottom to the phenomena of wear.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Au sein de la figure 1, illustrant l'état de la technique, on a représenté un schéma expliquant le fonctionnement du transport d'un fer crossé (8) quand il est installé dans un sac (1, 2, 7, 9). Le sac reçoit, par son ouverture supérieure (2), un fer crossé (8) qui s'installe au fond (3) du sac. Dans la pratique, il reçoit non pas un seul fer crossé, mais plusieurs arrangés en un faisceau.Within the figure 1 , illustrating the state of the art, there is shown a diagram explaining the operation of the transport of a cross iron (8) when it is installed in a bag (1, 2, 7, 9). The bag receives, through its upper opening (2), a cross iron (8) which is installed at the bottom (3) of the bag. In practice, he receives not a single cross-shaped iron, but several arranged in a beam.

Les bretelles du sac comme la bretelle (5) sont fixées en haut du sac du côté de son ouverture (2) par des soudures ou des coutures comme par exemple les coutures (6).The straps of the bag such as the strap (5) are fixed at the top of the bag on the side of its opening (2) by welds or seams such as seams (6).

Lorsque un crochet de grue (10) prend les bretelles (5) du sac, le poids du fer crossé (8) l'entraîne dans le fond du sac dans une position proche de son centre, et à sensiblement à l'aplomb (11) du crochet de grue (10).When a crane hook (10) takes the straps (5) of the bag, the weight of the cross-linked iron (8) drives it into the bottom of the bag in a position close to its center, and substantially vertically (11). ) of the crane hook (10).

Il en résulte que, quel que soit le nombre de fers crossés et leur masse, c'est toujours au même point central de la région (3) de fond de sac que le fer ou les fers crossés useront le matériau du sac.As a result, regardless of the number of knuckle irons and their mass, it is always at the same central point of the region (3) of the bottom of the bag that the iron or cross-shaped irons will wear the material of the bag.

Au sein de la figure 2, on a représenté le même système que celui de la figure 1, dans lequel le moyen de l'invention a été réalisé. Dans ce but, le sac de manutention sensiblement identique au sac de la figure 1, présente une ouverture supérieure (16) à travers laquelle a été chargé au moins un fer crossé (15). Le sac de manutention présente un fond (19) et des parois latérales (18).Within the figure 2 , we have represented the same system as that of the figure 1 in which the means of the invention has been realized. For this purpose, the handling bag substantially identical to the bag of the figure 1 , has an upper opening (16) through which has been loaded at least one cross iron (15). The handling bag has a bottom (19) and side walls (18).

Par ailleurs, le sac de l'invention comporte des anses ou bretelles destinées à être placées autour du crochet de levage. Un tel moyen de préhension ou de levage du sac de manutention par un crochet de levage est constitué par chacune une boucle complète comportant une partie libre (20, 21) destinée à venir sur le crochet de grue, et une partie (23) qui est soudée ou cousue sur la toile de la partie latérale (18) du sac.Furthermore, the bag of the invention comprises handles or straps intended to be placed around the lifting hook. Such means for gripping or lifting the handling bag by a lifting hook is constituted by each a complete loop comprising a free portion (20, 21) intended to come on the crane hook, and a portion (23) which is welded or stitched to the fabric of the side portion (18) of the bag.

Par ailleurs, la sangle constituant la bretelle du sac passe sous le fond du sac en une partie (22) qui n'est pas attachée au sac de sorte qu'elle affecte des plis, comme le pli (22), lorsque le sac est chargé.Moreover, the strap constituting the strap of the bag passes under the bottom of the bag in a portion (22) which is not attached to the bag so that it affects folds, such as the fold (22), when the bag is charge.

Il résulte de cette disposition que le bout crossé du fer (15) est guidé vers le fond du sac en dehors du croisement libre des diverses bretelles ou sangles (22).It follows from this arrangement that the cross-end of the iron (15) is guided towards the bottom of the bag outside the free crossing of various straps or straps (22).

Ainsi, un sac selon l'invention est apporté sur le chantier. Un manoeuvre place alors un lot de fers crossés dans le sac en les y introduisant par l'ouverture supérieure sans chercher particulièrement à disposer les fers dans le sac, mais en les posant sur le sol à travers le sac du même côté du sac, en une sorte de faisceau ou de botte libres de fers sensiblement parallèlement à leur plus grande dimension. Puis, lorsque le sac est considéré plein, il fait approcher le crochet de levage d'une grue et place les haussières des sangles sur le crochet. Le grutier commande alors un relevage de la charge qui est emportée.Thus, a bag according to the invention is brought to the site. A maneuver then places a batch of crossed knives in the bag by introducing them through the upper opening without particularly seeking to arrange the irons in the bag, but by placing them on the ground through the bag on the same side of the bag, a sort of bundle or boot free of irons substantially parallel to their largest dimension. Then, when the bag is considered full, it makes approach the hook of lifting of a crane and places the hawsers of the straps on the hook. The crane operator then controls a lift of the load that is carried.

Lors du début du mouvement de levage, le fond du sac étant libre des sangles, le bout crossé des fers vient en butée sur le tissu en un point qui se trouve en dehors du milieu du fond, mais en un point arbitrairement choisi d'un secteur latéral du fond en fonction de la position du sac lorsque le manoeuvre a chargé le sac.At the beginning of the lifting movement, the bottom of the bag being free of the straps, the cross-end of the irons abuts on the fabric at a point which lies outside the middle of the bottom, but at an arbitrarily chosen point of a lateral sector of the bottom depending on the position of the bag when the maneuver has loaded the bag.

Du fait que le sac se trouve dans une position quelconque, ce n'est jamais le même point ou le même secteur latéral du fond du sac qui reçoit en butée le bout crossé des fers.Because the bag is in any position, it is never the same point or the same lateral sector of the bottom of the bag which abuts the cross-end of the irons.

Il en résulte que l'usure est mieux répartie et le perçage évité ou retardé.As a result, wear is better distributed and drilling avoided or delayed.

Dans le cas d'une disposition à deux sangles (22) croisées, comme il sera expliqué à l'aide des figures suivantes, le fond du sac est partagé en quatre secteurs dans chacun desquels le bout du fer crossé peut venir se loger selon l'introduction arbitraire qui a été décidée lors du chargement du sac.In the case of an arrangement with two straps (22) crossed, as will be explained with the aid of the following figures, the bottom of the bag is divided into four sectors in each of which the tip of the cross iron can be housed according to the arbitrary introduction that was decided upon loading the bag.

Ainsi, on assure que lors de la vie du sac, ce n'est pas toujours le point central du fond de sac qui reçoit la charge des fers crossés, mais n'importe lequel des quatre secteurs qui partagent le fond de sac.Thus, it is ensured that during the life of the bag, it is not always the central point of the bag bottom that receives the load of the cross-shaped irons, but any of the four sectors that share the bottom of the bag.

Au sein de la figure 3, on a représenté une première vue d'un sac dans un autre mode de réalisation dans lequel les anses du sac sont composées par des boucles, comme les boucles (30) et (31), qui dépassent au-delà et au-dessus de l'ouverture (37) du sac qui présente des parois latérales et un fond comme décrit précédemment.Within the figure 3 there is shown a first view of a bag in another embodiment in which the handles of the bag are composed by loops, such as loops (30) and (31), which protrude beyond and above the opening (37) of the bag having sidewalls and a bottom as previously described.

Chaque bretelle ou anse comporte une partie (34) qui est attachée, soudée, ou cousue sur les parois du sac et qui passe ensuite en dessous du fond du sac de façon à se croiser sur un point de croisement central (36) avec une autre anse, comme l'anse (30) de la figure 3.Each strap or handle has a portion (34) which is attached, welded, or stitched to the walls of the bag and which then passes below the bottom of the bag so as to intersect at a central point of intersection (36) with another handle, like the handle (30) of the figure 3 .

On remarque qu'un espace (35) libre peut être aménagé entre le fond du sac et la boucle de retour sous le sac.Note that a free space (35) can be arranged between the bottom of the bag and the return loop under the bag.

La situation est mieux comprise à l'aide de la figure 4 dans laquelle deux sangles ou anses (40) et (41) sont visibles, tandis que le fond de sac (38) est nettement décollé de la partie retour (36) de la boucle (40, 41).The situation is better understood with the help of figure 4 wherein two straps or handles (40) and (41) are visible, while the bag bottom (38) is clearly detached from the return portion (36) of the loop (40, 41).

On a représenté en relation avec la figure 5 une vue en perspective du sac conforme à une autre forme de réalisation de l'invention en position érigée, c'est-à-dire déployée et donc propre à recevoir les éléments discrets à manutentionner, type armatures métalliques de renfort du béton, fers ou fers crossés, etc..We have shown in relation to the figure 5 a perspective view of the bag according to another embodiment of the invention in erected position, that is to say deployed and therefore adapted to receive the discrete elements to be handled, such as reinforcing metal reinforcement of concrete, irons or crooked irons, etc.

Ce sac est fondamentalement constitué d'une enveloppe (51), réalisée en matière synthétique tissée, telle que par exemple en polypropylène. Cette enveloppe est constituée d'un fond (52) et de parois latérales (53, 54, 55, 56), définissant globalement un parallélépipède, notamment un cube. Les parois latérales sont solidarisées au fond d'une part, et entre elles d'autre part, par le biais de coutures typiquement réalisées en polyamide (Nylon®).This bag is basically made of an envelope (51), made of woven synthetic material, such as for example polypropylene. This envelope consists of a bottom (52) and side walls (53, 54, 55, 56), defining generally a parallelepiped, including a cube. The side walls are secured to the bottom on the one hand, and between them on the other hand, through seams typically made of polyamide (Nylon ® ).

Comme dans les versions précédentes, ce sac est muni de moyens d'accrochage à un engin de levage, et de manière générale à un engin de manutention, telle qu'une fourche d'un chariot élévateur ou d'une grue ou tout système équivalent.As in previous versions, this bag is provided with means of attachment to a hoist, and generally to a handling machine, such as a fork of a forklift or a crane or any equivalent system .

Ces moyens d'accrochages sont constitués de sangles (57), solidarisées limitativement au niveau desdites parois latérales (53 à 56). Lesdites sangles définissent des anses de préhension (58) destinées à permettre leur prise en charge par la fourche dudit engin de levage.These hooking means consist of straps (57), integrally bounded at said side walls (53 to 56). Said straps define gripping loops (58) intended to allow their support by the fork of said lifting gear.

Comme pour les versions précédentes, au niveau du fond (52), lesdites sangles ne sont pas solidarisées à celui-ci voire même définissent une boucle lâche, pour ainsi complètement désolidariser le fond desdites sangles, et permettre une déformation du fond sous l'effet des produits que le sac est destiné à manutentionner.As for the previous versions, at the bottom (52), said straps are not secured to it or even define a loose loop, to completely separate the bottom of said straps, and allow deformation of the bottom under the effect products that the bag is intended to handle.

Ces sangles sont fixées à la surface extérieure desdites parois latérales (52 à 56) également par couture. Elles sont également réalisées en matériau synthétique, et présentent les caractéristiques de résistance mécanique suffisante en relation avec le poids que le sac est destiné à supporter.These straps are attached to the outer surface of said sidewalls (52-56) also by stitching. They are also made of synthetic material, and have the characteristics of sufficient mechanical strength in relation to the weight that the bag is intended to support.

Selon cette forme particulière de réalisation de l'invention, chacune des parois latérales (53 à 56) est en fait constituée d'une double peau, respectivement une peau intérieure (59) et une peau extérieure (60), définissant entre elles un volume (61), destiné à recevoir une plaque rigide (62). Cette plaque rigide s'étend avantageusement sur toute ou sensiblement toute la largueur de la paroi considérée et sensiblement sur toute sa hauteur.According to this particular embodiment of the invention, each of the side walls (53 to 56) is in fact made of a double skin, respectively an inner skin (59) and an outer skin (60), defining between them a volume (61) for receiving a rigid plate (62). This rigid plate advantageously extends over all or substantially all the width of the wall considered and substantially over its entire height.

Ces plaques rigides (62) sont relativement minces afin de ne pas obérer le poids général du sac. Elles peuvent être réalisées en acier, en matériau plastique rigide éventuellement renforcé, et par exemple en polypropylène alvéolé. Elles peuvent encore être réalisées en bois, voire en carton.These rigid plates (62) are relatively thin so as not to overweight the overall weight of the bag. They may be made of steel, rigid plastic material optionally reinforced, and for example polypropylene honeycomb. They can still be made of wood or even cardboard.

Selon une première variante de cette forme de réalisation de l'invention, ces plaques rigides sont fixées à demeure au sein de chacune des parois latérales (53 - 56) du sac. Dans cette configuration, les bords supérieurs de chacune des deux peaux (59 et 60) de chacune des parois latérales sont solidarisés l'un à l'autre, par exemple par couture, après bien évidemment insertion des plaques rigides dans le volume (61) défini par les deux peaux.According to a first variant of this embodiment of the invention, these rigid plates are fixed permanently within each of the side walls (53-56) of the bag. In this configuration, the upper edges of each of the two skins (59 and 60) of each of the side walls are secured to one another, for example by sewing, after obviously inserting the rigid plates in the volume (61). defined by the two skins.

Selon une autre variante avantageuse de l'invention, les plaques rigides (62) sont amovibles, et donc escamotable hors des parois latérales, et ce, dans un souci de permettre le stockage des sacs hors manutention, donc après pliàge, selon un encombrement réduit. Dans cette configuration, les bords supérieurs libres de chacune des deux peaux (59, 60) sont solidarisables réversiblement l'un à l'autre, par exemple au moyen d'un système Velcro® (non représenté), ou de tout autre système équivalent dès lors que la réversibilité de la solidarisation est obtenue.According to another advantageous variant of the invention, the rigid plates (62) are removable, and therefore retractable out of the side walls, and this, for the sake of allowing the storage of bags out of handling, so after folding, in a reduced space . In this configuration, the free upper edges of each of the two skins (59, 60) are reversibly securable to one another, for example by means of a Velcro ® system (not shown), or any other equivalent system. since the reversibility of the joining is obtained.

Ce faisant, lors de l'utilisation du sac, il suffit de désolidariser les deux extrémités supérieures des deux peaux, d'insérer les plaques rigides dans chacune des parois latérales et de refermer réversiblement lesdites extrémités supérieures pour disposer d'un sac prêt à l'emploi.In doing so, when using the bag, it is sufficient to separate the two upper ends of the two skins, to insert the rigid plates in each of the side walls and to reversibly close said upper ends to have a bag ready for use. 'employment.

Selon une autre variante de cette forme de réalisation de l'invention, le fond (52) du sac reçoit en son sein une plaque rigide (63), par exemple de même nature que celle insérée dans les parois latérales, toujours dans l'objectif d'optimiser la résistance au frottement, la pérennité et la réalisation des sacs. En raison de son positionnement, cette plaque (63) est simplement déposée sur le fond de l'enveloppe (51), ses dimensions étant choisies pour être callée naturellement et de par son propre poids au fond de ladite enveloppe. Cette plaque (63) est de fait amovible, et peut également être retirée de l'enveloppe pour les besoins de stockage des sacs.According to another variant of this embodiment of the invention, the bottom (52) of the bag receives within it a rigid plate (63), for example of the same nature as that inserted in the side walls, still in the lens to optimize the resistance to friction, the durability and the realization of the bags. Due to its positioning, this plate (63) is simply deposited on the bottom of the casing (51), its dimensions being chosen to be naturally pressed and by its own weight at the bottom of said casing. This plate (63) is de facto removable, and can also be removed from the envelope for the storage needs of the bags.

En outre, et selon encore une autre variante, le fond (52) de l'enveloppe peut également être constitué d'une double peau. Dans cette configuration, les deux peaux sont solidarisées entre elles sur toute leur périphérie, n'ayant pas vocation à recevoir entre elles ladite plaque de fond selon la forme de réalisation précédente, mais simplement à optimiser la résistance à l'usure dudit fond.In addition, and according to yet another variant, the bottom (52) of the envelope may also consist of a double skin. In this configuration, the two skins are joined together over their entire periphery, not intended to receive between them said bottom plate according to the previous embodiment, but simply to optimize the wear resistance of said bottom.

On s'est aperçu que sur chantiers, les sacs de manutention pouvaient servir à des fonctions différentes, par exemple parce qu'ils doivent être utilisés dans des parties de chantier différentes ou avec des produits à lever différents ou qu'ils doivent être manipulés par des équipes de manutention différentes.It was found that on building sites, the bags could be used for different functions, for example because they must be used in different parts of the site or with different products to lift or they must be handled by different handling teams.

Dans ce but, il est prévu que les sangles ou bretelles des sacs portent des éléments de reconnaissance visuelle qui permettent notamment au grutier qui manoeuvre l'outil de préhension (10) des bretelles ou anses des sacs de manutention de reconnaître à distance la destination du sac.For this purpose, it is expected that the straps or shoulder straps of the bags carry visual recognition elements that allow the crane operator who manipulates the gripping tool (10) straps or handles of the bags to recognize remotely the destination of the bag.

Dans un mode particulier de réalisation, on utilise une couleur déterminée ou une teinte pour au moins l'une des sangles ou bretelles du sac. Il peut aussi s'agir d'un motif coloré comme dans le cas d'une sangle bicolore dont la couleur de fond forme un contraste avec au moins une autre couleur répartie selon un dessin déterminé et reconnaissable à distance.In a particular embodiment, a specific color or shade is used for at least one of the straps or shoulder straps of the bag. It can also be a colored pattern as in the case of a two-color strap whose background color forms a contrast with at least one other color distributed in a specific pattern and recognizable remotely.

Dans un autre mode particulier de réalisation, la couleur déterminée est une couleur verte. On notera que cette disposition peut être aussi réalisée à l'aide d'un moyen de codage sans contact comme une étiquette électronique de genre RFID, solidarisée à une sangle du moyen d'accrochage et qui est alors lisible à distance avec un lecteur d'étiquettes RFID. Bien entendu, le nombre de bretelles, ainsi que leur disposition autour du sac n'est pas limité. Il suffit que les bretelles se croisent sous le fond du sac, qu'elles soient libres du fond du sac et qu'elles soient attachées sur les parois latérales du sac sur une distance suffisante pour renforcer le sac de manutention.In another particular embodiment, the determined color is a green color. Note that this arrangement can also be achieved using a contactless coding means such as an RFID-type electronic tag, secured to a strap of the attachment means and which is then remotely readable with a reader. RFID tags. Of course, the number of straps and their arrangement around the bag is not limited. It is sufficient that the straps cross under the bottom of the bag, they are free from the bottom of the bag and they are attached to the side walls of the bag a distance sufficient to strengthen the bag.

De même, il est possible de ménager un accrochage sur le crochet de la grue sous forme d'une anse, d'une boucle ou d'une boucle repliée.Similarly, it is possible to arrange a hooking on the hook of the crane in the form of a loop, a loop or a folded loop.

En particulier dans le cas d'une boucle repliée telle qu'elle a été représentée à la figure 3, la partie libre de la sangle servant à former l'anse est repliée en haut du sac et cousue par une couture (32) de façon à former une boucle (31). Cette disposition est visible sur les boucles (40 et 41) de la figure 4.Especially in the case of a folded loop as shown in FIG. figure 3 , the free portion of the strap forming the handle is folded at the top of the bag and sewn by a seam (32) so as to form a loop (31). This arrangement is visible on the loops (40 and 41) of the figure 4 .

On conçoit tout l'intérêt du sac de manutention conforme à l'invention de par l'optimisation de sa résistance à l'usure née des frottements des matériaux susceptibles d'être manutentionnés par de tels sacs, notamment des éléments discrets.All the advantages of the handling bag according to the invention are conceived by the optimization of its resistance to wear caused by the friction of the materials that can be handled by such bags, in particular discrete elements.
