Abstract

The invention relates to a device making it possible to correct, without the risk of injury, a difference in altitude between two points in order to allow loads to be raised over a small distance. It is made up of a knob (1) exhibiting orifices (7) in which the end of any object (8) is inserted. A bearing base (2) is connected to the knob (1) and provided with a fixed spindle (4). When the user exerts, on the knob (1), a force antagonistic to that of any object (7), he or she moves the knob (1) on the fixed spindle (4) and the bearing base (2) exerts a pressure on the support surface (11) without rubbing. The device according to the invention is particularly intended for any apparatus having a difference in vertical elevation between two points.

Description

DESCRIPTION
DISPOSITIF POUR CORRIGER UNE DIFFERENCE D'ELEVATION
VERTICALE ENTRE DEUX POINTS : VERIN DE REGLAGE
La présente invention concerne un dispositif pour un appareil, qui placé sous des charges, permet de les soulever sur une faible course.DESCRIPTION
DEVICE FOR CORRECTING A DIFFERENCE IN ELEVATION
VERTICAL BETWEEN TWO POINTS: ADJUSTMENT JACK
The present invention relates to a device for an apparatus which, placed under loads, makes it possible to lift them over a short stroke.

L'utilisation de ces vérins de réglage est traditionnellement effectuée à l'aide de la main, ce qui risque de blesser celle-ci. The use of these adjustment cylinders is traditionally carried out using the hand, which risks injuring the latter.

Certains de ces vérins de réglage comportent une zone en creux ou en relief pour recevoir un outil sans avoir recours à l'aide de la main, mais en n'éliminant pas les risques de blessures et l'utilisation d'un outil spécifique. Some of these adjustment cylinders have a recessed or raised area for receiving a tool without having to use the hand, but without eliminating the risk of injury and the use of a specific tool.

Le dispositif selon l'invention permet de remédier à ces inconvénients. The device according to the invention overcomes these drawbacks.

Il comporte en effet une molette présentant des orifices par lesquels est introduit l'extrémité de n'importe quel objet pour le réglage du vérin et une embase d'appui sur la molette.It in fact comprises a thumb wheel having holes through which the end of any object is introduced for adjusting the jack and a support base on the thumb wheel.

Cette molette qui permet de démultiplier l'effort exercé par l'utilisateur est pourvue d'un évidement circulaire qu'un anneau élastique solidarise à l'embase d'appui, quand l'utilisateur réalise un mouvement sur la molette autour de l'axe fixe, l'embase d'appui exerce une pression sur la surface sans frotter. This wheel which allows the effort exerted by the user to be multiplied is provided with a circular recess which an elastic ring fixes to the support base, when the user makes a movement on the wheel around the axis fixed, the support base exerts pressure on the surface without rubbing.

Selon une forme de réalisation préférentielle, la molette constitue une partie du vérin de réglage, une zone de moindre épaisseur formant 1 'embase d'appui. L'axe est solidaire de la molette et de son support. Le dispositif peut-être réalisé en métal et/ou en matière plastique, en une seule opération de moulage par injection. According to a preferred embodiment, the thumbwheel constitutes a part of the adjustment jack, a zone of reduced thickness forming one support base. The axis is integral with the wheel and its support. The device can be made of metal and / or plastic, in a single injection molding operation.

Selon une variante, la molette peut-être pourvue d'une partie clipsable, dispositifs à pattes utilisant la fléxibilité de la matière permettant d'assembler l'embase d'appui, sans apport de segment. According to a variant, the thumbwheel may be provided with a clip-on part, tab devices using the flexibility of the material making it possible to assemble the support base, without adding a segment.

Les dessins annexés illustrent l'invention
La figure 1 représente, en coupe, le dispositif selon l'invention.The accompanying drawings illustrate the invention
Figure 1 shows, in section, the device according to the invention.

La figure 2 représente, en coupe, une variante de ce dispositif. Figure 2 shows, in section, a variant of this device.

Le dispositif représenté sur la figure 1 comporte une molette (1) et une embase d'appui (2) ayant des dimensions de l'ordre de 6 centimètres pour le diamètre, et de 3 centimètres pour la hauteur. Dans le centre de la molette, un orifice a une forme correspondante à celle d'un trou cylindrique, dont la surface interne est creusée d'un sillon en hélice pour le logement d'un filet d'axe (3). The device shown in Figure 1 comprises a wheel (1) and a support base (2) having dimensions of the order of 6 centimeters for the diameter, and 3 centimeters for the height. In the center of the wheel, an orifice has a shape corresponding to that of a cylindrical hole, the internal surface of which is hollowed out with a helical groove for housing a pin thread (3).

L'axe (4) est fixe dans son support (5).  The axis (4) is fixed in its support (5).

La surface de l'axe porte une saillie hélicoïdale destinée à s'enfoncer en tournant, assurant le déplacement de la molette (1) sur l'axe fixe (4). The surface of the axis carries a helical projection intended to sink while turning, ensuring the displacement of the wheel (1) on the fixed axis (4).

La molette (1) est pourvue d'un évidement circulaire qu'un anneau élastique (6) solidarise à l'embase d'appui (2). Dans la face de la surface cylindrique de la molette (1), des orifices (7) ont une forme correspondante à celle de l'extrémité d'un objet quelconque (8). The thumbwheel (1) is provided with a circular recess which an elastic ring (6) attaches to the support base (2). In the face of the cylindrical surface of the wheel (1), orifices (7) have a shape corresponding to that of the end of any object (8).

La longueur d'un objet quelconque (8) et la position des orifices (7) par rapport au lien non rigide sont telles qu'une faible pression exercée par l'utilisateur sur l'objet quelconque (8) est démultipliée, et permet une rotation de la molette autour de l'axe fixe (4), permettant ainsi de rattraper la différence d'altitude entre deux points. The length of any object (8) and the position of the orifices (7) relative to the non-rigid link are such that a low pressure exerted by the user on any object (8) is multiplied, and allows a rotation of the wheel around the fixed axis (4), thus making it possible to make up for the difference in altitude between two points.

Dans la forme de réalisation selon la figure 2, la molette (1) comporte un rebord clipsable (9), contre lequel l'orifice (10) de l'embase d'appui (2) vient s'emboiter par déformation élastique. In the embodiment according to FIG. 2, the thumbwheel (1) has a clip-on flange (9), against which the orifice (10) of the support base (2) fits together by elastic deformation.

Le dispositif selon l'invention est particulièrement destiné à tout appareil ayant une différence d'élévation verticale entre deux points.  The device according to the invention is particularly intended for any device having a difference in vertical elevation between two points.
