Abstract

The stone grips consist of a hook plate (23) with a slot (24) for a crane hook or lifting bar. The sides of the plate have elongated holes (45,46) for two cranked levers (9,10). The levers are fitted at the ends with friction pads (33,34) bolted to the pads. A central beam (38) is also attached to the back of the pads and to the corner bolts (11,12). The beam is fitted with a perpendicular holding bar (4) fitted with end handles (7,8).

Description

L'invention a trait à un dispositif de manutention, en particulier à une pince pour le déplacement de fardeaux de forme parallélépipédique et notamment pour le déplacement des bordures de trottoirs. The invention relates to a handling device, in particular a gripper for moving bundles of parallelepiped shape and in particular for moving curbs.

Les bordures de trottoirs, réalisées dans la plupart des cas en granit, présentent une forme parallélépipédique et ont un poids relativement élevé. De ce fait, leur manutention est assez difficile et notamment sur les chantiers puisqu'en général, cette manutention se fait manuellement. Cet inconvénient est aggravé du fait que ces bordures ne présentent aucun moyen de préhension. Ainsi, on est amené à utiliser-des moyens empiriques. Il arrive que ces bordures glissent des mains des ouvriers procédant, soit au chargement et/ou au déchar- gement, soit à la pose sur le chantier de ces éléments lourds, ce qui peut, non seulement, provoquer des accidents plus ou moins graves, mais également la casse de la bordure. The curbs, made in most cases of granite, have a parallelepiped shape and have a relatively high weight. Therefore, their handling is quite difficult and especially on construction sites since in general, this handling is done manually. This drawback is aggravated by the fact that these edges have no gripping means. Thus, we are led to use empirical means. Sometimes these edges slip from the hands of workers carrying out either the loading and / or unloading, or the laying on the site of these heavy elements, which can not only cause more or less serious accidents, but also the breakage of the border.

La présente invention a pour but de fournir, à titre de produit industriel nouveau, un moyen permettant.la manutention aisée et facile de ces bordures ét, en général, de tout fardeau ayant une forme parallélépipédique. The object of the present invention is to provide, as a new industrial product, a means allowing the easy and easy handling of these edges and, in general, of any burden having a parallelepiped shape.

A cet effet, l'invention concerne un dispositif de manutention, en particulier une pince, pour le dépiacement de fardeaux de forme parallélépipédique et, notamment pour le déplacement des bordures de trottoirs, caractérisé en ce qu'il comporte au moins deux poussoirs amovibles se faisant face l'un à l'autre et coopérant avec un train de leviers interpose entre les poussoirs et des moyens de levage, la force de préhension de. ces poussoirs, exercée sur les deux faces parallèles du fardeau, étant fonction du poids de la charge. To this end, the invention relates to a handling device, in particular a gripper, for the removal of bundles of parallelepiped shape and, in particular for the movement of curbs, characterized in that it comprises at least two removable pushers facing each other and cooperating with a train of levers interposes between the pushers and lifting means, the gripping force of. these pushers, exerted on the two parallel faces of the load, being a function of the weight of the load.

L'invention sera bien comprise en se référant à la description suivante faite à titre d'exemple non limitatif et au dessin ci-annexé dans lequel~:~ - la figure 1 est une vue en perspective du dispositif de manutention conforme à l'invention, - la figure 2 estune vue.ident,ique a-e1le.-de la figure--1j sèul-le moyen de levage étant modifié. mdifi6.  The invention will be better understood by referring to the following description given by way of nonlimiting example and to the attached drawing in which ~: ~ - Figure 1 is a perspective view of the handling device according to the invention , - Figure 2 is a vue.ident, ique a-e1le.-of the figure - 1j sèul-the lifting means being modified. mdifi6.

Le dispositif de manutention-l comporte un support horizontal 2 disposé perpendiculairement au fardeau 3. Ce support 2 est traversé en son centre par une tringle de guidage, 4 présentant à chaque extrémité 5, 6 une poignée 7, 8.  The handling device-1 comprises a horizontal support 2 disposed perpendicularly to the burden 3. This support 2 is crossed in its center by a guide rod, 4 having at each end 5, 6 a handle 7, 8.

Ainsi, il est possible de diriger manuellement cetdispositif-de-manutention 1 lors de son utilisation.Thus, it is possible to manually direct this handling-device 1 during its use.

Chaque extremité 9, 10 du support 2 est traversée par un axe d'articulation 11, 12 servant d'éléments de liaison entre le support 2 et deux paires de leviers 13,14 et 15,16. Les leviers 13,14 et 15,16 de chaque paire sont disposés de part et d'autre du support 2 et forment ainsi une chape pour ledit support 2. Ces leviers 13 à 16 ont la forme d'un Z. Une des ailes paralleles 17,18 et 19,20 est reliée par un axe d'articulation 21, 22 à une plaque de levage 23 présentant une lumière verticale 24 à travers laquelle on engage le crochet 25, soit d'un dispositif de levage 26, soit d'une barre de levage 27 pour un déplacement manuel du fardeau (voir figure 2). Each end 9, 10 of the support 2 is crossed by a hinge pin 11, 12 serving as connecting elements between the support 2 and two pairs of levers 13, 14 and 15, 16. The levers 13, 14 and 15, 16 of each pair are arranged on either side of the support 2 and thus form a yoke for said support 2. These levers 13 to 16 have the shape of a Z. One of the parallel wings 17, 18 and 19, 20 is connected by a hinge pin 21, 22 to a lifting plate 23 having a vertical lumen 24 through which the hook 25 is engaged, either of a lifting device 26, or of a lifting bar 27 for manual movement of the load (see FIG. 2).

On dispose, entre les deux ailes paralleles 28, 29 et 30, 31 des leviers 13 à 16, ltextrémité 32 d'un poussoir amovible 33 et 34, cette extrémité 32 entant reliée aux ailes 28 à 31 par un axe d'articulation 35. Les poussoirs 33, 34 se faisant face et dont seul le poussoir 33 est visible sur les dessins, traversent une joue verticale 36, 37 solidaire du chant inférieur 38 du support 2. La longueur des poussoirs amovibles 33, 34 peut être variable en fonction des différentes fourchettes d'épaisseurs des fardeaux. There are, between the two parallel wings 28, 29 and 30, 31 of the levers 13 to 16, the end 32 of a removable plunger 33 and 34, this end 32 being connected to the wings 28 to 31 by a hinge pin 35. The pushers 33, 34 facing each other and of which only the pushbutton 33 is visible in the drawings, pass through a vertical cheek 36, 37 secured to the lower edge 38 of the support 2. The length of the removable pushers 33, 34 can be variable depending on the different ranges of load thicknesses.

Les axes d'articulation 11, 12 sont placés sur la bissectrice 39, 40 de l'angle 41, 42 reliant le bras principal 43,. 44 aux ailes paralleles 28 à 31. The articulation axes 11, 12 are placed on the bisector 39, 40 of the angle 41, 42 connecting the main arm 43,. 44 with parallel wings 28 to 31.

En exerçant une traction verticale dirigée vers le haut sur la plaque de levage 23, les axes d'articulation 21, 22, coulissant dans les lumieres 44, 45 approximativement horizontales, exercent à leur tour une traction sur les ailes 17 à 20 des leviers 13 à 16 provoquant la rotation desdits leviers 13 a 16 autour des axes d'articulation 11, 12. De ce fait, les poussoirs 33, 34, sous l'action des ailes 28 à 31, sont appliqués contre les faces paralleles 47, 48 du fardeau 3. Plus le fardeau 3 est lourd plus il sera nécessaire d'exercer une force de levage et, de ce fait, plus la force de préhension des poussoirs 33, 34 est grande. By exerting a vertical traction directed upwards on the lifting plate 23, the articulation axes 21, 22, sliding in the lights 44, 45 approximately horizontal, exert in their turn a traction on the wings 17 to 20 of the levers 13 to 16 causing the rotation of said levers 13 to 16 about the axes of articulation 11, 12. As a result, the pushers 33, 34, under the action of the wings 28 to 31, are applied against the parallel faces 47, 48 of the burden 3. The heavier the burden 3 the more it will be necessary to exert a lifting force and, therefore, the greater the gripping force of the pushers 33, 34.

Pour éviter un glissement du fardeau 3, on peut pourvoir la face de contact 49 des poussoirs 33, 34 d'aspérités pouvant s'incruster dans le fardeau 3 ou de matériaux rugueux annihilant tout glissement. To avoid a sliding of the burden 3, one can provide the contact face 49 of the pushers 33, 34 with roughness which can become embedded in the burden 3 or with rough materials annihilating any sliding.

Bien que l'invention ait été décrite à propos d'une forme de réalisation particulière, il est bien entendu qu'elle n'y est nullement limitée et qu'on peut y apporter diverses modifications de formes, de-matériaux et de combinaisons de ces divers éléments, sans pour cela s'éloigner du cadre et de ltesprit de l'invention.  Although the invention has been described in connection with a particular embodiment, it is understood that it is in no way limited thereto and that it is possible to make various modifications to it in terms of shapes, materials and combinations of these various elements, without departing from the scope and the spirit of the invention.
