Abstract

The portable jack-actuated shears are used on accident damaged vehicle bodies, using the thrust of a jack to drive inter-articulating blades through pin-jointed struts and a piston yoke. The jack may be connected to a pump by a flexible pipe, attached the the body of the shears by a screw thread on its head. 'U' section pieces may house onto the heels of the blades, drilled to locate the pins securing the output ends of the struts. The blades may be drilled to receive the fulcrum axle mounted on the body, together with the yoke axle.

Description

L'objet de l'invention concerne un dispositif de cisaille portative pour sectionner les carrosseries de véhicules accidentés. The object of the invention relates to a portable shear device for cutting the bodies of damaged vehicles.

Il consiste en des perfectionnements apportés pour augmenter la puissance de coupe et la rapidité d'intervention. It consists of improvements made to increase the cutting power and the speed of intervention.

Dans les dispositifs connus les transmissions absorbaient partie de la puissance alors que le poids des appareillage diminuait la maniabilité de la cisaille. In the known devices, the transmissions absorbed part of the power while the weight of the devices reduced the maneuverability of the shears.

Le dispositif suivant l'invention supprime ces inconvénients et assure une plus grande rapidité de sectionnement avec un allègement améliorant l'efficacité des interventions pour les services de secours. The device according to the invention eliminates these drawbacks and ensures greater speed of sectioning with lightening improving the effectiveness of the interventions for the emergency services.

Il est constitué par un vérin hydraulique effectuant une poussée par deux biellettes qui directement reliées aux lames leurs transmettent une force égale et se ferment en meme temps sur les parties des carrosseries à sectionner. It is constituted by a hydraulic cylinder carrying out a thrust by two rods which directly connected to the blades transmit an equal force to them and close at the same time on the parts of the bodies to be cut.

Sur les dessins annexés donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention
La figure 1 représente vu en élévation les éléments formant la cisaille.In the accompanying drawings given by way of nonlimiting example of one of the embodiments of the subject of the invention
Figure 1 shows in elevation the elements forming the shears.

La figure 2 montre vue en perspective la pompe actionnant le vérin. Figure 2 shows a perspective view of the pump actuating the cylinder.

La cisaille est constituée (Fig 1) par un vérin hydraulique 1 relié à la pompe à main transportable 2 (Fig 2). Cette pompe peut etre hydro-air ou même un moteur thermique. The shears are constituted (Fig 1) by a hydraulic cylinder 1 connected to the transportable hand pump 2 (Fig 2). This pump can be hydro-air or even a heat engine.

La liaison de la pompe au vérin est obtenue par un flexible 3 qui a une longueur suffisante pour atteindre toutes les parties d'un véhicule. The connection of the pump to the jack is obtained by a hose 3 which has a sufficient length to reach all parts of a vehicle.

Sur ce vérin est fixé le corps de cisaille 4 par son vissage sur le pas 16 se trouvant à la partie supérieure du vérin. On this cylinder is fixed the shear body 4 by its screwing on the pitch 16 located at the upper part of the cylinder.

Sur le corps 4 se fixe le levier de maintien 4'. On the body 4 is fixed the holding lever 4 '.

La chape de piston 5 reçoit les biellettes 6, 7, qui tourillonnent autour de l'axe 8.  The piston yoke 5 receives the rods 6, 7, which rotate around the axis 8.

Chaque lame 9, 10 est montée sur la partie haute 11, 12, des biellettes 6, 7, s'articulent sur les axes 13, 14 et orifices 19, 20, 21, 22. Each blade 9, 10 is mounted on the upper part 11, 12, connecting rods 6, 7, are articulated on the axes 13, 14 and orifices 19, 20, 21, 22.

L'arbre d'articulation 15 se fixe sur la partie haute du vérin et l'arbre 8 sur la chape 5. The articulation shaft 15 is fixed on the upper part of the jack and the shaft 8 on the yoke 5.

Les lames 9, 10, comportent à leur partie inférieure des profils d'entrainement 17, 18 avec orifices de tourillonnement 19, 21, recevant la poussée des biellettes, alors que les orifices 20, 22, reçoivent l'axe d'articulation et de support. The blades 9, 10 have, at their lower part, drive profiles 17, 18 with journaling orifices 19, 21, receiving the thrust of the rods, while the orifices 20, 22, receive the axis of articulation and support.

Le piston 5 par son déplacement transmet intégralement sans déperdition de puissance la forcedu vérin 1 aux lames 9, 10. The piston 5 by its displacement transmits integrally without loss of power the force of the jack 1 to the blades 9, 10.

Une multiplication de puissance est obtenue par les bras de levier formés par les biellettes. A multiplication of power is obtained by the lever arms formed by the rods.

La course est réduite mais 1 'ampleur du mouvement parfaitement synchronisée avec une instantanéité et une puissance accrues. The stroke is reduced but the range of motion perfectly synchronized with instantaneousness and increased power.

La maniabilité de la cisaille par le manche 4 et la prise formée par le corps 3 et même le vérin 1 sont facilitées. On peut atteindre avec une grande précision la partie à découper. The maneuverability of the shears by the handle 4 and the grip formed by the body 3 and even the jack 1 are facilitated. The part to be cut can be reached with great precision.

Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour cela la conception générale de 1' invention qui vient d'être décrite.  However, the shapes, dimensions and arrangements of the various elements may vary within the limit of equivalents, as indeed the materials used for their manufacture, without thereby changing the general design of the invention which has just been described.
