Abstract
Description
La présente invention se rapporte à un dispositif de manutentionThe present invention relates to a handling device
auto serrant sous l'action gravitaire d'un bloc à déplacer. self-tightening under the gravitational action of a block to be moved.
Pour le transport de blocs constructifs tels que des briques ou des moellons par exemple, il est déjà connu du document DE 28 1 5 766 5 de réaliser un dispositif de manutention auto serrant comprenant deux bras en partie parallèles articulés l'un par rapport l'autre autour d'un axe de rotation. Une poignée est également fixée autour de ce dernier, et il en découle que lorsque ce dispositif est positionné autour d'un bloc et qu'un manutentionnaire tire sur la poignée afin de le soulever, les deux bras 10 viennent prendre appui contre deux faces verticales opposées du bloc et exercent des contraintes suffisantes sur ces dernières pour autoriser le transport du bloc. For the transport of building blocks such as bricks or rubble stones for example, it is already known from document DE 28 1 5 766 5 to produce a self-tightening handling device comprising two partly parallel arms articulated one relative to the other around an axis of rotation. A handle is also fixed around the latter, and it follows that when this device is positioned around a block and a handler pulls on the handle in order to lift it, the two arms 10 come to bear against two vertical faces opposite of the block and exert sufficient constraints on them to authorize the transport of the block.
Un tel dispositif présente néanmoins un inconvénient important lorsque l'on souhaite positionner ledit dispositif sur le bloc ou ôter ledit 15 dispositif du bloc. En effet, pour effectuer une telle opération, le dispositif étant auto serrant dès l'instant o l'on agit directement sur la poignée, le manutentionnaire doit donc saisir les deux bras du dispositif, les maintenir écarter, et enfin exercer une traction vers le bas ou vers le haut selon qu'il cherche à positionner le dispositif autour du bloc ou à ôter le dispositif 20 dudit bloc. Or, ceci peut être délicat à exécuter lorsque le bloc est positionné entre deux autres blocs latéraux et que les espaces latéraux ménagés entre les différents blocs sont réduits. Such a device nevertheless has a significant drawback when it is desired to position said device on the block or to remove said device from the block. Indeed, to carry out such an operation, the device being self-tightening from the moment when one acts directly on the handle, the handler must therefore grasp the two arms of the device, keep them apart, and finally exert traction towards the down or up depending on whether it seeks to position the device around the block or to remove the device 20 from said block. However, this can be difficult to execute when the block is positioned between two other side blocks and the side spaces provided between the different blocks are reduced.
La présente invention a pour but de remédier à l'inconvénient cité précédemment, et consiste pour cela en un dispositif de manutention 25 auto serrant sous l'action gravitaire d'un bloc à déplacer, ce dispositif comprenant deux bras parallèles destinés à prendre appui contre deux faces verticales opposées du bloc, lesdits bras étant reliés l'un à l'autre par une articulation, caractérisé en ce que les deux bras présentent respectivement, à leur extrémité supérieure, pour l'un, un retour de plus 30 grande longueur formant poignée de portage, et pour l'autre, un retour de déverrouillage de plus petite longueur s'étendant sous la poignée de portage. The object of the present invention is to remedy the drawback mentioned above, and for this consists of a self-tightening handling device 25 under the gravitational action of a block to be moved, this device comprising two parallel arms intended to bear against two opposite vertical faces of the block, said arms being connected to each other by a hinge, characterized in that the two arms respectively have, at their upper end, for one, a return of greater length forming carrying handle, and for the other, a shorter unlocking return extending under the carrying handle.
Ainsi, lorsque le manutentionnaire se saisit à la fois du retour de verrouillage et du retour formant poignée de portage, cette dernière est 35 plaquée contre le retour de verrouillage et il en résulte que les deux bras sont automatiquement écartés l'un de l'autre dans la zone de contact prévue avec le bloc. Ce dispositif de manutention peut donc être positionné ou ôté sans que l'écartement des deux bras découle d'une intervention manuelle directe sur ces derniers. Thus, when the handler takes hold of both the locking return and the return forming the carrying handle, the latter is pressed against the locking return and the result is that the two arms are automatically separated from one another. in the contact area provided with the block. This handling device can therefore be positioned or removed without the spacing of the two arms resulting from direct manual intervention on the latter.
Avantageusement, l'articulation reliant les deux bras est plus 5 proche du bras prolongé par le retour formant poignée de portage que du bras prolongé par le retour de déverrouillage. Advantageously, the articulation connecting the two arms is closer to the arm extended by the return forming a carrying handle than to the arm extended by the unlocking return.
Selon une première variante de réalisation préférée de l'invention, les deux bras sont reliés l'un à l'autre par l'intermédiaire d'une chape sur laquelle est articulée une traverse. According to a first preferred embodiment of the invention, the two arms are connected to each other by means of a yoke on which a cross member is articulated.
Selon une seconde variante de réalisation préférée de l'invention, les deux bras sont reliés l'un à l'autre par l'intermédiaire de deux traverses articulées l'une sur l'autre. According to a second preferred variant embodiment of the invention, the two arms are connected to one another by means of two crosspieces articulated one on the other.
Préférentiellement, le retour formant poignée de portage possède une longueur sensiblement égale à la plus petite distance séparant 15 les deux bras. Preferably, the return forming a carrying handle has a length substantially equal to the smallest distance separating the two arms.
Avantageusement, ce dispositif comporte des moyens de réglage de l'écartement entre les deux bras. Cela permet son adaptation à la manutention de différents types de blocs. Advantageously, this device comprises means for adjusting the spacing between the two arms. This allows it to be adapted to the handling of different types of blocks.
Suivant une possibilité, la traverse comporte plusieurs trous 20 destinés au passage de l'axe d'articulation sur la pièce, traverse ou chape, solidaire de l'autre bras. According to one possibility, the cross member has several holes 20 intended for the passage of the hinge pin on the part, cross member or yoke, integral with the other arm.
L'invention sera mieux comprise à l'aide de la description détaillée qui est exposée ci-dessous en regard du dessin annexé dans lequel: La figure 1 est une vue en perspective d'un dispositif de manutention selon l'invention. The invention will be better understood using the detailed description which is set out below with reference to the appended drawing in which: FIG. 1 is a perspective view of a handling device according to the invention.
La figure 2 est une vue de face du dispositif de manutention représenté à la figure 1 au cours de son positionnement autour d'un bloc ou de son enlèvement d'un bloc. Figure 2 is a front view of the handling device shown in Figure 1 during its positioning around a block or its removal from a block.
La figure 3 est une vue de face du dispositif de manutention représenté à la figure 2 au cours du transport du bloc. Figure 3 is a front view of the handling device shown in Figure 2 during transport of the block.
A la figure 1 est représenté un dispositif de manutention 1 auto serrant sous l'action de gravitaire d'un bloc à déplacer. In Figure 1 is shown a handling device 1 self tightening under the action of gravity of a block to move.
Plus précisément, ce dispositif de manutention 1 comprend 35 deux bras 2, 3 parallèles reliés l'un à l'autre par l'intermédiaire d'une traverse 4 qui est rattachée au bras 3 et qui est mobile en rotation autour d'un axe de rotation A solidaire d'une chape 5 rattachée au bras 2. La traverse 4 et la chape 5 sont conçues de façon à ce que l'axe de rotation A soit situé beaucoup plus près du bras 2 que du bras 3. More specifically, this handling device 1 comprises two parallel arms 2, 3 connected to one another by means of a cross-member 4 which is attached to the arm 3 and which is movable in rotation about an axis of rotation A secured to a yoke 5 attached to the arm 2. The cross member 4 and the yoke 5 are designed so that the axis of rotation A is located much closer to the arm 2 than to the arm 3.
La traverse 4 comporte plusieurs trous 1 2, ici au nombre de 5 deux, pour l'engagement de l'axe de rotation A, l'utilisation d'un trou ou de l'autre permettent de modifier l'écartement entre les bras 2 et 3. The cross member 4 has several holes 1 2, here 5 in number two, for the engagement of the axis of rotation A, the use of one hole or the other makes it possible to modify the spacing between the arms 2 and 3.
Les deux bras 2, 3 présentent respectivement, à leur extrémité supérieure, un retour de plus grande longueur formant poignée de portage 6, et un retour de déverrouillage 7 de plus petite longueur 10 s'étendant sous la poignée de portage 6. La longueur de la poignée de portage 6 est sensiblement égale à la plus petite distance séparant les deux bras 2, 3. The two arms 2, 3 respectively have, at their upper end, a return of greater length forming a carrying handle 6, and an unlocking return 7 of shorter length 10 extending under the carrying handle 6. The length of the carrying handle 6 is substantially equal to the smallest distance separating the two arms 2, 3.
En se référant à la figure 2, on observe que le positionnement du dispositif de manutention 1 autour d'un bloc 8 adéquat s'effectue de la 15 facon suivante. Le manutentionnaire se saisit à la fois de la poignée de portage 6 et du retour de déverrouillage 7 à l'aide d'une seule main (non représentée). Ce faisant, la poignée de portage 6 se retrouve plaquée contre le retour de déverrouillage 7, et la traverse 4 pivote autour de l'axe de rotation A dans le sens trigonométrique. Par conséquent, comme 20 représenté à la figure 2, les deux bras 2, 3 sont amenés à s'écarter l'un de l'autre au niveau de leur extrémité inférieure 9. La distance séparant les deux bras 2, 3 en partie basse étant alors supérieure à la longueur du bloc 8, le dispositif de manutention 1 peut être finalement abaissé et positionné autour de deux faces 10 verticales opposées dudit bloc 8. Referring to FIG. 2, it can be seen that the positioning of the handling device 1 around an adequate block 8 is carried out in the following manner. The handler takes hold of both the carrying handle 6 and the unlocking return 7 with one hand (not shown). In doing so, the carrying handle 6 is found pressed against the unlocking return 7, and the cross member 4 pivots around the axis of rotation A in the trigonometric direction. Consequently, as shown in FIG. 2, the two arms 2, 3 are made to move apart from each other at their lower end 9. The distance separating the two arms 2, 3 at the bottom then being greater than the length of the block 8, the handling device 1 can finally be lowered and positioned around two opposite vertical faces 10 of said block 8.
Comme représenté à la figure 3, dès l'instant o le manutentionnaire libère le retour de déverrouillage 7, la traverse 4 pivote autour de l'axe de rotation A dans le sens des aiguilles d'une montre et la distance séparant les extrémités inférieures 9 des deux bras 2, 3 se trouve par conséquent réduite. Lorsque le manutentionnaire se saisit de la poignée 30 de portage 6 uniquement et exerce une traction suffisante vers le haut pour soulever le bloc 8, les extrémités inférieures 9 des bras 2, 3 tendent à se rapprocher et permettent de maintenir le bloc 8 en suspension. As shown in Figure 3, from the moment the handler releases the unlocking return 7, the crosspiece 4 pivots around the axis of rotation A in a clockwise direction and the distance between the lower ends 9 of the two arms 2, 3 is therefore reduced. When the handler takes hold of the carrying handle 6 only and exerts sufficient upward traction to lift the block 8, the lower ends 9 of the arms 2, 3 tend to approach and allow the block 8 to be suspended.
Une fois le transport effectué, pour libérer le dispositif de manutention 1 du bloc 8, il suffit au manutentionnaire de se saisir de la 35 poignée de portage 6 et du retour de déverrouillage 7, puis de tirer le dispositif de manutention 1 vers le haut. Once the transport has been carried out, in order to release the handling device 1 from the block 8, the handler just has to grasp the carrying handle 6 and the unlocking return 7, then pull the handling device 1 upwards.
Bien que non représenté sur les figures 1 à 3, il doit être bien compris que les faces internes des deux bras 2, 3 peuvent être chacune équipées d'au moins un patin afin d'améliorer le contact entre lesdits bras 2, 3 et les faces 10 verticales opposées du bloc 8. Although not shown in FIGS. 1 to 3, it should be understood that the internal faces of the two arms 2, 3 can each be equipped with at least one shoe in order to improve the contact between said arms 2, 3 and the opposite vertical faces 10 of block 8.
Bien que l'invention ait été décrite en liaison avec des exemples particuliers de réalisation, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention. Although the invention has been described in connection with particular examples of embodiment, it is obvious that it is in no way limited thereto and that it includes all the technical equivalents of the means described as well as their combinations if these fall within the scope of the invention.
