  • the free end of the inner tube portion is adapted to cooperate with a support plate adapted to be able to support against said object.
  • the lever arrangement is to consist of a retainer unit, secured to the upper end portion of the outer tube portion, where said retainer unit supports a locking mechanism, active against the inner tube portion and a separate felling lever.
  • the locking cooperation of the retainer unit utilises a gear rack coordinated with and associated to the inner tube section.
  • a "U"-shaped stirrup cooperates with the retainer unit over which a separate felling lever, such as lever, can rest as a pivotal point for a two-armed lever system, where the one end of the lever facing towards said inner tube portion is adapted to cooperate with a cog in a gear rack, while the other end of the lever is caused to be displaced downwards by a manual force, the inner tube portion being raised and in such a raised position permitting the locking mechanism to assume a locking position for the inner tube portion.
  • a separate felling lever such as lever
  • Said resilient means is adapted to automatically be able to displace the inner tube portion upwards through the outer tube portion and against an urging abutment of the uppermost end portion of the inner tube portion against the object and that the tube portion can be locked in this position, whereafter the lever arrangement can be activated in order successively to displace the inner tube portion out of the outer tube portion.
  • a resilient means in the form of a gas spring is on the one hand to be secured to the one tube portion and on the other hand to be secured to the other tube portion, that said tube portions are fixedly locked relative to one another in a fully retracted position with the aid of a means locking a relative movement in the form of a pin, to be able to absorb a compressive force generated by the resilient means, in order on a release of said locking means to permit the inner tube portion to a displacement movement relative to the outer tube portion up towards the object.
  • FIG. 1 illustrates in three sequences how a prior art arrangement can lift an object in the form of a private car

Abstract

La présente invention concerne un dispositif (1) servant entre autre de support ou d'étai, dans l'utilisation, en tout cas, de deux portions de tube (2, 3) télescopiquement coordonnées et orientées de manière concentrique, sachant que ces portions peuvent être verrouillées en place l'une par rapport à l'autre par une tige (9) afin que ledit support ou étai puisse supporter un objet (4) ; elles peuvent aussi être reliées l'une à l'autre de manière mobile afin qu'une fonction de levage puisse supporter et élever un objet par levier (7) présenté ci-après. Un moyen élastique (6) est fixé d'un côté (6a) à l'une des portions de tube (2) et fixé à l'autre portion (3) de l'autre côté (6b). Lesdites portions de tube (2, 3) sont également fixées l'une à l'autre à l'aide d'un moyen (5) verrouillant un mouvement relatif. Lors du relâchement dudit verrouillage (9), la section intérieure de tube (3) est amenée en déplacement relativement à la section de tube externe (2).
