Abstract

The heated gun softens sticks of thermoplastic paste. The gun has a handle (1) with a hole (2) at the back to insert a thermoplastic paste stick (3). A trigger (5) advances the stick so that it enters a cylinder heated by an electric heating coil (11). The temperature is set using a sliding potentiometer (12) on the side of the gun.

Description

d'une partie fixe dudit outil.of a fixed part of said tool.

La présente invention concerne un dispositif chauffant par une résistance électrique pour permettre le ramollissement de bâtons de pâtes thermoplastiques avec réglage de la température en fonction du type de pâte utilisée. Le ramollissement de ces bâtons de pâte à usage de l'art Dentaire se pratique traditionnellement par chanffage direct à la flamme d'un réchaud type à gaz ou à alcool ou par immersion dans de l'eau chaude, d'o tâtonnement et difficulté d'obtenir le ramollissement à la  The present invention relates to a device heating by an electrical resistance to allow the softening of sticks of thermoplastic doughs with adjustment of the temperature according to the type of dough used. The softening of these dough sticks for dental use is traditionally practiced by direct flame chanffing of a standard gas or alcohol stove or by immersion in hot water, where groping and difficulty d '' get softening at the

température exacte désirce.exact temperature desired.

Le dispositif selon l' invention permet de remédier à cette difficulté d'amener et maintenir les  The device according to the invention overcomes this difficulty of bringing and maintaining the

A chaque couleur correspond une température d'utilisation déterminée par le fabricant: - vert: température d'utilisation: 50 - 51 C - gris: température d'utilisation: 53 - 54 C - rouge: température d'utilisation: 55 - 56 C Le dispositif comporte en effet, selon une première caractéristique, une pièce à main constituée d'un boîtier présentant un orifice par lequel sera introduit le bâton de pâte, une poignce comportant une gâchette permettant de le faire avancer par simple pression du doigt jusqu'à la buse de sortie, un bouton de réglage de température agissant sur une résistance qui chauffe le  Each color has an operating temperature determined by the manufacturer: - green: operating temperature: 50 - 51 C - gray: operating temperature: 53 - 54 C - red: operating temperature: 55 - 56 C The device indeed comprises, according to a first characteristic, a handpiece consisting of a housing having an orifice through which the stick of dough will be introduced, a handle comprising a trigger making it possible to advance it by simple pressure of the finger until the outlet nozzle, a temperature adjustment button acting on a resistor which heats the

bâton à la température préalablement définie.  stick at the previously defined temperature.

Les dessins annexés illustrent l' invention: - la figure 1 représente, en coupe, le dispositif de l' invention au premier stade de la manipulation lors de  The accompanying drawings illustrate the invention: - Figure 1 shows, in section, the device of the invention at the first stage of handling during

l' introduction du bâton de pâte.the introduction of the dough stick.

- la figure 2 représente, en coupe, le dispositif de l' invention au stade d'avancement du bâton lors de la pression sur la gâchette En référence à ces dessins le dispositif se compose d'une pièce à main ( 1) avec orifice d' introduction ( 2) ayant un diamètre correspondant au diamètre du bâton de pâte ( 3) - environ 8 mm -, 2 - une buse de sortie ( 4), une gâchette ( 5) permettant par action du doigt de l'utilisateur d'actionner le système d' articulation ( 6) afin de faire soulever la pièce étau (7) de blocage du bâton ( 3) et de faire coulisser la pièce de guidage ( 8)sur glissière dans  - Figure 2 shows, in section, the device of the invention at the stage of advancement of the stick when the trigger is pressed With reference to these drawings the device consists of a handpiece (1) with orifice d 'introduction (2) having a diameter corresponding to the diameter of the dough stick (3) - about 8 mm -, 2 - an outlet nozzle (4), a trigger (5) allowing by action of the user's finger to activate the articulation system (6) in order to raise the vice piece (7) blocking the stick (3) and to slide the guide piece (8) on slide in

l'axe du cylindre ( 9).the axis of the cylinder (9).

Un ressort ( 10) est prévu pour permettre à la gachette de revenir à sa position initiale lors du relachement. Une résistance électrique ( 11) permet de chauffer le cylindre ( 9) et ramollir le bâton ( 3)  A spring (10) is provided to allow the trigger to return to its initial position during release. An electrical resistance (11) makes it possible to heat the cylinder (9) and soften the stick (3)
