Abstract

The device has elementary modules (1) with male and female parts (2, 3) that permit locking between the modules. Each module has linear teeth (5) on both sides, where teeth overlap with either gears (6) or worm that permit erection or retraction of a rod which is formed by the locked modules. A container (7) contains non locked modules (1) that are stored on a plane perpendicular to an axis of the rod.

Description

La présente invention concerne un dispositif mécanique de vérin modulaireThe present invention relates to a mechanical device of modular jack

à longueur résiduelle restreinte.with restricted residual length.

Le dispositif suivant l'invention permet d'ériger ou de rétracter une tige rigide de section constante, formée de 05 modules élémentaires verrouillables entre eux.  The device according to the invention allows to erect or retract a rigid rod of constant section, formed of 05 elementary modules lockable together.

Le stockage des éléments non verrouillés peut se faire sur un plan perpendiculaire à l'axe de la tige, ce qui permet de n'occuper à la base de la tige et dans l'axe, qu'une longueur résiduelle restreinte.  The storage of the unlocked elements can be done on a plane perpendicular to the axis of the rod, which allows to occupy at the base of the rod and in the axis, a restricted residual length.

Les vérins utilisés jusqu'ici ont une longueur résiduelle lorsque la tige est rentrée, supérieur à la moitié de la longueur, lorsque la tige est sortie, sauf dans le cas des vérins télescopiques qui a une longueur résiduelle supérieure à la longueur maximale de la tige divisé par le nombre d'éléments, ce dernier étant limité par la réduction de section entre chaque élément.  The jacks used so far have a residual length when the rod is retracted, greater than half the length, when the rod is out, except in the case of telescopic jacks which has a residual length greater than the maximum length of the rod divided by the number of elements, the latter being limited by the reduction of section between each element.

Le dispositif suivant l'invention est constituée: De modules élémentaires (1) de section: soit octogonale, soit rectangulaire, soit de forme cylindrique avec une fente(16) de guidage, soit de forme cylindrique et filetée, soit de section composite ou quelconque; chaque élément a une partie mâle (2) et femelle (3) permettant le verrouillage entre eux, ces dernières sont dotées: soit d'un filetage, soit d'un système de crochetage, soit d'un système verrouillage à billes. Un mécanisme adapté au type de verrouillage est placé à la base de la tige. Il s'agira dans le cas du filetage: d'un engrenage (4) percé en son centre d'un trou de section correspondante à celle des éléments.  The device according to the invention consists of: Elementary modules (1) of section: either octagonal, rectangular or cylindrical in shape with a slot (16) for guiding, or of cylindrical and threaded shape, or of composite section or any ; each element has a male part (2) and female (3) for locking between them, the latter are provided with either a thread or a hooking system, or a ball lock system. A mechanism adapted to the type of lock is placed at the base of the rod. It will be in the case of threading: a gear (4) drilled in the center of a corresponding section hole to that of the elements.

Chaque élément est muni de denture linéaire (5) sur une ou plusieurs faces, dans cette denture vient s'imbriquer soit un ou des engrenages (6), soit une ou des vis sans fin, qui permettent érection ou la rétraction de la tige.  Each element is provided with linear teeth (5) on one or more faces, in this toothing is interlocked either one or gears (6) or one or worm, which allow erection or retraction of the rod.

Le dispositif suivant l'invention est constituée aussi: De bagues de guidage (9) ; d'un réservoir (7) servant de magasin 2868061 2 contenant les éléments non verrouillés, sa forme est tubulaire, il peut être linéaire ou enroulé, sa section est adaptée à celle des éléments, et aux courbures; il est constitué aussi de pièces de maintien et de pièces transmissions des mouvements.  The device according to the invention also consists of: guide rings (9); a reservoir (7) serving as a magazine 2868061 2 containing the unlocked elements, its shape is tubular, it can be linear or wound, its section is adapted to that of the elements, and the curvatures; it also consists of holding parts and parts transmissions movements.

Un lien élastique (10) de type ressors de traction peut relier les éléments modulaires voisins, entre eux, l'accrochage de ce lien sera libre de toute rotation.  An elastic link (10) of the type of pull springs can connect the neighboring modular elements, between them, the attachment of this link will be free of any rotation.

Les éléments modulaires peuvent être munis d'alésages (11)de manière que la tige puis faire fonction de tuyaux pour le passage de gaz, de liquides, de lumière ou ondes électromagnétiques, des joints (12) assurent l'étanchéité, Les éléments modulaires peuvent être munis de conducteurs (13 et de contacts (14) électriques, chaque élément verrouillé assurant la continuité avec ces voisins, de manière à pouvoir conduire des courants ou des signaux électriques, pour cela le corps de chaque élément modulaire sera en tout ou partie en matériaux isolant.  The modular elements may be provided with bores (11) so that the rod then act as pipes for the passage of gases, liquids, light or electromagnetic waves, seals (12) provide sealing, modular elements can be provided with electrical conductors (13 and contacts (14), each locked element ensuring continuity with these neighbors, so as to be able to conduct currents or electrical signals, for this the body of each modular element will be wholly or partially made of insulating materials.
