Description
Tournevis L'objet de la présente invention est un tournevis, caractérisé par une tête destinée à s'appliquer sur la tête de la vis, par une lame de tournevis disposée axialement dans cette tête,
par un espace fermé situé au-dessus de celle-ci et par un piston actionnable de l'extérieur et déplaçable dans l'espace susmention né formant cylindre, de façon que, le piston étant enfoncé dans son cylindre, on puisse placer la tête sur la vis puis, en retirant le piston, créer,
dans le cylindre, un vide permettant à la pression atmosphé rique extérieure de maintenir la vis contre la. tête.
Le dessin: ci-annexé représente, à titre d'exemple, une, forme d'exécution de l'objet de la préstnte in- vention.
La fig. 1 en est une vue en plan et 1a fig. 2, une coupe verticale axiale.
L'outil représenté comprend un carter 1, de for me cylindrique, divisé intérieurement en trois cham bres superposées la, lb et 1c. Dans la chambre médiane lb est montée librement une douille 2 pré- sentant une rainure intérieure hélicoïdale 3.
A l'extré mité inférieure die cette douille est emmanché de façon, interchangeable, un tournevis 4.
5 est un poussoir qui est déplaçable axialement à l'encontre d'un ressort 6 logé dans la chambre la et qui est relié à la douille 2 par le moyen, d'une bille 7, chassée dans le poussoir et pénétrant dans la rainure hélicoïdale 3.
A la partie inférieure du carter 1 est montée de façon amovible, une tête 8 légèrement élastique, en nylon par exem ple, dans l'axe de laquelle pénètre la lame 9 du tour nevis 4.
La chambre 1c du carter 1 est aménagée en un cylindre dans lequel peut se déplacer le piston 10 ; celui-ci est muni d'une garniture en caoutchouc 11 et un ressort de rappel 12 tend constamment à le pous ser vers -le haut.
Ce piston se commande au moyen d'une bague horizontale 13 reliée au piston par deux tiges verticales 14 diamétralement opposées et qui peuvent coulisser dans des rainures longitudinales 15 du carter.
Lorsque l'on veut transporter une vis à sa place de travail et l'y visser, on déplace vers le bas la bague 13 jusqu'à ce que le piston 10-11 occupe la partie inférieure de la chambre 1c, puis on coiffe la vis avec la tête 8 comme montré en fig. 2 et on abandonne la bague 13 ;
le piston 1011 remonte créant un vidé. dans la partie inférieure de la chambre 1c ; dès lors, la pression atmosphérique extérieure appliquera contre la tête 8, la, vie que l'on pourra ainsi trans porter à l'endroit voulu. Ceci fait, on déplace vers le bas le poussoir 5, qui,
à son tour, fait descendre la douille 2 jusqu'à ce que la lame 9 du tournevis ait pénétré d'ans la fente de la vis. A partir de ce moment 14 douille 2 ne pouvant plus descendre, si l'on con- tinue à agir sur le poussoir 5, celui-ci fera tourner autour de son axe la douille 2 et la lame 4.
Screwdriver The object of the present invention is a screwdriver, characterized by a head intended to be applied on the head of the screw, by a screwdriver blade disposed axially in this head,
by a closed space located above the latter and by a piston actuable from the outside and movable in the aforementioned space forming a cylinder, so that, the piston being pressed into its cylinder, the head can be placed on the screw then, by removing the piston, create,
in the cylinder, a vacuum allowing the external atmospheric pressure to maintain the screw against the. head.
The accompanying drawing represents, by way of example, one embodiment of the object of the present invention.
Fig. 1 is a plan view thereof and FIG. 2, an axial vertical section.
The tool shown comprises a casing 1, of cylindrical form, divided internally into three superimposed chambers 1a, 1b and 1c. In the middle chamber lb is freely mounted a bush 2 having a helical inner groove 3.
At the lower end of the die, this socket is interchangeably fitted with a screwdriver 4.
5 is a pusher which can be moved axially against a spring 6 housed in the chamber 1a and which is connected to the bush 2 by means of a ball 7, driven into the pusher and entering the helical groove 3.
A slightly elastic head 8, made of nylon for example, in the axis of which penetrates the blade 9 of the screwdriver 4 is mounted in the lower part of the housing 1 in a removable manner.
The chamber 1c of the casing 1 is arranged in a cylinder in which the piston 10 can move; this is provided with a rubber gasket 11 and a return spring 12 constantly tends to push it upwards.
This piston is controlled by means of a horizontal ring 13 connected to the piston by two vertical rods 14 diametrically opposed and which can slide in longitudinal grooves 15 of the housing.
When you want to transport a screw to its working place and screw it there, the ring 13 is moved downwards until the piston 10-11 occupies the lower part of the chamber 1c, then the cap is capped. screw with head 8 as shown in fig. 2 and we abandon ring 13;
the piston 1011 rises creating a vacuum. in the lower part of the chamber 1c; therefore, the external atmospheric pressure will apply against the head 8, the life which can thus be transported to the desired location. This done, push-button 5 is moved downwards, which,
in turn, lower the socket 2 until the blade 9 of the screwdriver has entered the slot in the screw. From this moment 14 bush 2 can no longer descend, if one continues to act on the pusher 5, the latter will turn the bush 2 and the blade 4 around its axis.
