Abstract

Two different and alternative support stands for laboratory test tubes. In each case the test tube is gripped in a circumferential clip with non-slip lining. The clip is integrally backed with a circular permanent magnet with a coaxial, cylindrical spigot. The first stand has a horizontal base with vertical steel plate which has horizontal channels into which the spigot fits. The second stand has a rising steel arm with several spaced holes each sized to accept the spigot. Each stand can hold a tube at various heights and at selected angles.

Description

DESCRIPTION
La présente invention concerne un dispositif pour porter les tubes à essai de Laboratoire.DESCRIPTION
The present invention relates to a device for carrying laboratory test tubes.

Le porte tubes à essai est traditionnellement conçu à l'aide de deux planchettes superposées, sur lesquelles sont aménagés sur deux rangées ou plus des trous d'un même diamètre, afin dy introduire les tubes, les disposant verticalement. The test tube holder is traditionally designed using two superimposed boards, on which are arranged in two or more rows of holes of the same diameter, in order to introduce the tubes, arranging them vertically.

I1 en existe aussi en métal de même configuration, où les tubes étant simplement placés à l'intérieur des trous les maintiens verticalement, sans pouvoir les disposer d'aucune autre manier.  I1 also exists in metal of the same configuration, where the tubes being simply placed inside the holes hold them vertically, without being able to dispose of them in any other way.

Le dispositif selon l'invention permet de remedier à cet inconv vénient. n comporte en effet deux formes différentes, dont un socle sur lequel est adapté une plaque avec plusieurs échancrures horizontales, et une plaque courbée, perpendiculaire en an.ut, avec plusieurs échancrures rondes en fonction de la n auteur utilisabl- permettant deux types différents d'utiliser les tubes; ou vient se loger une saillie, évitant tout glissement de l'ensemble adap- tée sur l'aimant, muni d'une pince rétractable, qui permet la fixation et la stabilité du tube. The device according to the invention makes it possible to remedy this inconvenience. n indeed has two different shapes, including a base on which is fitted a plate with several horizontal notches, and a curved plate, perpendicular in an.ut, with several round notches according to the author n usable - allowing two different types of 'use the tubes; or a projection is accommodated, preventing any sliding of the assembly adapted to the magnet, provided with a retractable clamp, which allows the fixing and the stability of the tube.

Selon une forme de réalisation préfdrentielle,la plaque réalisée en fer comporte plusieurs échancrures. L'assemblage de la pince rétractable en acier trempé, et de l'aimant permanent, permet la formation de la saillie par rivetage en laiton. Les parois intérieures de la pince rétractable sont recouvertes d'une matière antidérapante empêchant tout glissement du tube. According to a preferred embodiment, the plate made of iron has several notches. The assembly of the retractable clamp in hardened steel, and the permanent magnet, allows the formation of the projection by brass riveting. The interior walls of the retractable clamp are covered with a non-slip material preventing any slipping of the tube.

Le figure I représente, en coupe, un dispositif selon l'in- vention. FIG. I represents, in section, a device according to the invention.

La figure 2 représente, en coupe, la pose de tubes des deux côtés de la plaque.  Figure 2 shows, in section, the laying of tubes on both sides of the plate.

La figure 3 représente, de face, le dispositif selon l'invention. Figure 3 shows, from the front, the device according to the invention.

La figure 4 représente, de face, une variante de ce dispositif. Figure 4 shows, from the front, a variant of this device.

La figure 5 représente, en coupe, le dispositif selon la va riante. FIG. 5 represents, in section, the device according to the variant.

Le dispositif représenté sur la figure I comporte un socle (I) sur lequel est adapté une plaque (2) de 5mm d'épaisseur, où se trouve une échancrure horizontale (7) de Tmm de profondeur, où vient se loger une saillis (8) qui est fixée sur une des faces de l'aimant permanent (3) pour permettre la pose facile et l'u tilisation pratique du tube (6).Sur l'aimant (3) est accolé une pince rétractable (4) qui permet de maintenir et de retirer le tube (6) dont l'intérieur est pourvu d'une matière antidéra pante (5) dans laquelle est introduit le tube (6)
Le dispositif représenté sur la figure 2 comporte un socle (I) sur lequel est adapté une plaque (2) pourvue de plusieurs échancrures horizontales (7j disposées sur chaque face, afin de mul tiplier la pose des tubes (6)
le dispositif représenté sur la figure 3 comporte une pince rétractable (4) dont l'écartement permet la visualisation du liquide contenu dans le tube (6)
Dans la forme de réalisation selon la figure 4 le socle (I) légèrement en retrait par rapport à la plaque (IO) courbée à sa base et perpendiculaire à l'autre extrémité, permet et facilite l'iRclinaison et le prélèvement dans le tube (6) en libérant ainsi une main de l'utilisateur. Les échancrures rondes (9)rap- prochées les unes des autres permettent l'ajustement fonctionnel du tube (6)
La figure 5 représente, en coupe, le dispositif selon la figure 4
Le dispositif selon l'invention est particulièrement destiné porter les tubes à essai de Laboratoire. The device shown in Figure I comprises a base (I) on which is adapted a plate (2) of 5mm thick, where there is a horizontal notch (7) Tmm deep, where a projection is housed (8 ) which is fixed on one side of the permanent magnet (3) to allow easy installation and practical use of the tube (6). On the magnet (3) is attached a retractable clamp (4) which allows hold and remove the tube (6), the interior of which is provided with an anti-slip material (5) into which the tube (6) is inserted
The device represented in FIG. 2 comprises a base (I) on which is fitted a plate (2) provided with several horizontal notches (7j arranged on each face, in order to multiply the laying of the tubes (6)
the device shown in Figure 3 includes a retractable clamp (4) whose spacing allows the visualization of the liquid contained in the tube (6)
In the embodiment according to FIG. 4, the base (I) slightly recessed with respect to the plate (IO) curved at its base and perpendicular to the other end, allows and facilitates the inclination and the removal from the tube ( 6) thereby freeing a hand from the user. The recessed notches (9) brought close to each other allow the functional adjustment of the tube (6)
Figure 5 shows, in section, the device according to Figure 4
The device according to the invention is particularly intended for carrying the laboratory test tubes.
