Abstract

The manual lifting tool for blocks used in building comprises an X-shaped frame (1) held together by a central bolt (6). Hook-shaped jaws (2) at the lower end of the frame hold the block. A chain (3) links the top ends of the frame and passes through a section of pipe (4) which acts as a handle.

Description

-1 La présente invention concerne un dispositif pour la préhension de toutThe present invention relates to a device for grasping everything

bloc de construction. Traditionnellement, les blocs de construction sont manipulés avec les mains de l'ouvrier et obligeant souvent celui-là à se baisser.  building block. Traditionally, building blocks are handled with the hands of the worker and often force the worker to bend down.

Les maux induits par cette manipulation peuvent être des traumatismes de la main, du dos et des articulations (coude, genou). Le dispositif selon l'invention permet de soulager les efforts de préhension et par la même les maux induits.  The evils induced by this manipulation can be traumatic of the hand, the back and the joints (elbow, knee). The device according to the invention makes it possible to relieve the gripping efforts and consequently the evils induced.

En effet, le croisillon a pour rôle de reporter les efforts verticaux du poids de l'objet à soulever sur les faces latérales et horizontales permettant un pincement. L'effort de levage est facilité. La tenue de l'objet est également améliorée, l'ensemble favorisant ainsi les conditions de travail de l'ouvrier d'un point de vue sécurité santé d'une part et qualité d'autre part. Les dessins annexés illustrent l'invention : La figure (1) représente en coupe le dispositif de l'invention. La figure (2) représente en plan le dispositif de l'invention.  Indeed, the role of the brace is to postpone the vertical forces of the weight of the object to be lifted on the lateral and horizontal faces allowing a pinch. The lifting force is facilitated. The holding of the object is also improved, the whole thus promoting the working conditions of the worker from a point of view of health safety on the one hand and quality on the other hand. The accompanying drawings illustrate the invention: Figure (1) shows in section the device of the invention. Figure (2) shows in plan the device of the invention.

La figure (3) représente en perspectives le dispositif de l'invention. Les pièces des l'outil seront repérées en figure (3). En référence à ces dessins, le dispositif comporte un croisillon (1), des crochets (2), un lien souple au moins sur une portion de sa longueur (3), une poignée (4), des articulations extérieures (5), une articulation axiale (6). A titre d'exemple d'utilisation, l'opérateur de blocs peut exécuter des actions de préhension et de manipulation en 4 temps. Le premier est la prise en main du dispositif, le deuxième est la mise en prise de l'outil sur le bloc, le troisième est l'action de soulever et de manipuler le bloc, le quatrième est la dépose du bloc induisant une détente de la pince, laquelle peut aussitôt resservir à réitérer l'opération. -2 Les dimensions et les matériaux de fabrication sont variables, leur choix sera fait en fonction des dimensions, du poids, et de l'état de surface de l'objet à soulever. La rugosité des crochets (2) peut à titre d'exemple être 5 améliorée (pointes, rainures).  Figure (3) shows in perspective the device of the invention. The parts of the tool will be identified in figure (3). With reference to these drawings, the device comprises a spider (1), hooks (2), a flexible link at least over a portion of its length (3), a handle (4), external joints (5), a axial joint (6). As an example of use, the block operator can perform actions of gripping and manipulation in 4 times. The first is the grip of the device, the second is the engagement of the tool on the block, the third is the action of lifting and manipulating the block, the fourth is the removal of the block inducing a relaxation of the forceps, which can immediately be used again to repeat the operation. -2 The dimensions and the materials of manufacture are variable, their choice will be made according to the dimensions, the weight, and the state of surface of the object to be lifted. The roughness of the hooks (2) may for example be improved (tips, grooves).
