Description

Deut artif'%ielle ä pivot. Artificial stem with pivot.

Lobjet de 1'invention est une dent arti ficielle ä pivot. Le pivot de cette dent est constitue par une feudle m6tallique Ws mince dopt wie Partie presente des moyens de retenue, 1'au tre Partie ayant son extremite taillee en Pointe et presentarrt au meins une ferste lorr gitudinale qui permet, apres avoir introduit cette Partie ä, travers une ouverture corres pondante dune Plaque arriere metallique, de recourber lateralement sur celle-ei les Parties formees par la ou les fentes dans des sens opposes pour fixer sur cette Plaque la dent artificielle portant 1e pivot, qui est fix6 dans cette derniere dass 1e sens de sa longueur avec sa Partie presentant des moyens de retenue. Le dessin annex6 represerite, ä titre d'exemple, une forme d'ex6cution de 1'objet de 1'invention. La fig. 1 est une eldvation de cöte mon trant une forme d'execution de la dent arti ficielle ä pivot et la Position de ce dernier dann la dent; The object of the invention is an artificial pivot tooth. The pivot of this tooth is made up of a thin metal leaf with a thin part having retaining means, the other part having its end cut into a point and presenting at least a firm lorr gitudinale which allows, after having introduced this part to , through a corresponding opening of a metal rear plate, to bend laterally thereon the parts formed by the slot(s) in opposite directions in order to fix on this plate the artificial tooth bearing the first pivot, which is fixed in the latter in the first direction of its length with its Part having retaining means. The appended drawing shows, by way of example, one form of execution of the object of the invention. fig. 1 is a side elevation showing one form of execution of the artificial tooth with pivot and the position of the latter in the tooth;

La fig. 2 est une vue en perspective du pivot de la meme forme d'execution; La fig. 3 montre la Position du pivot Jans la dent en section transversale; La fig. 4 en est une vue semblable, les Parties saillantes du pivot 6tant r-ecourb6es; La fig. 5 est un plan de la fig. 3 ; La fig. 6 est un plan de la fig. 4. En r6ference au dessin, 1e pivot est cons titue par une feuille tres mince et presentant une Partie de base 1 fixde dans la dent 2 et qui est de forme trapezoidale afin d'etre re tenue solidement dans 1e corps de celle-ei. Dans cette forme d'execution les cöt6s incli nes 4 de la Partie 1 du pivot constituent des moyens de retenue pour celui-ei. La Partie du pivot faisant saillie de la dent 2 est di visee en deux Parties 5 et 6 par une ferste longitudinale 7, et les extremitds sup6rieures de chacune de ces Parties pr6serrtent une Partie inclinee 8 et 9 formant ainsi pour chacune d'elles ä. proximit6 de la ferste 7 respective ment les pointes 10 et 11 qui sorrt adjacentes de maniere que lorsqu'on introduit 1e pivot dann une ouverture correspondante dune Plaque arriere 12, olles agissent effectivement comme une simple Pointe. fig. 2 is a perspective view of the pivot of the same embodiment; fig. 3 shows the position of the pivot Jans tooth in cross section; fig. 4 is a similar view, the projecting parts of the pivot being re-curved; fig. 5 is a plan of FIG. 3; fig. 6 is a plan of FIG. 4. With reference to the drawing, the pivot is made up of a very thin sheet and having a base part 1 fixed in tooth 2 and which is trapezoidal in shape in order to be firmly held in the body of the latter. In this embodiment, the inclined sides 4 of Part 1 of the pivot constitute retaining means for the latter. The part of the pivot protruding from the tooth 2 is divided into two parts 5 and 6 by a longitudinal ferste 7, and the upper ends of each of these parts pr6serrtent an inclined part 8 and 9 thus forming for each of them ä. proximity to the ferste 7 respectively ment the spikes 10 and 11 which sorrt adjacent so that when the first pivot is introduced into a corresponding opening in a rear plate 12, they effectively act as a simple spike.

Une dent artificielle pourvue d'un pivot selon 1'invention se fixe comme suit: Le pivot dass sa Position tolle quelle est representee par los fig. 1, 3 et 5 du dessin est introduit Jans une ouverture correspon- dante dune Plaque arriere 12, de maniere quo cette derniere s'applique contre la Partie posterieure de la dent artificielle et quo los deux Parties 5 et 6 du pivot fassent saillie de 1'autre cöte de la Plaque. An artificial tooth provided with a pivot according to the invention is fixed as follows: The pivot in its tolle position which is represented by los fig. 1, 3 and 5 of the drawing is introduced in a corresponding opening of a rear plate 12, so that the latter is applied against the posterior part of the artificial tooth and that the two parts 5 and 6 of the pivot protrude by 1 other side of the Plate.

0n recourbe alors chacune de ces Parties sur un cöte lateral opposd de 1'ouverture de la Plaque 12 ainsi quo cela est represente aux fig. 4 et 6 du dessin. 0n then bends each of these Parts on a lateral side opposite the opening of the Plate 12 as shown in FIGS. 4 and 6 of the drawing.

La Partie 1 du pivot peut par exemple etre cuite Jans 1e corps de la dent 2. Part 1 of the pivot can for example be baked on the body of tooth 2.

La presente invention pertnet de fabriquer des pivots dune Brande solidite, dune ma- nipulation facile et permet wie forte econo- mie de metal. . The present invention makes it possible to manufacture pivots of brande solidity, of easy handling and allows great economy of metal. .

Claims

CLAIM Artificial tooth ä, pivot, characterized in that its pivot consists of a very thin metal sheet, one part of which has retaining means, the other part having its end cut into a point and having at least one slot which allows, after having introduced this Part through a corresponding opening of a metal Back Plate, to bend laterally thereon the Parts formed by the slot(s) in opposite directions in order to fix the artificial tooth on this Plate. as the first pivot, which is fixed in the latter in the first direction of its length with its Part having retaining means. SUB-CLAIMS 1 Tooth according to claim, characterized in that the part of its pivot protruding from the tooth has a slot arranged vertically with respect to the rear face of the tooth.

2 Tooth according to claim, characterized in that the part of its pivot which is fixed in the tooth is of trapezoidal shape, its widest part being at its end.

3 Tooth according to claim, characterized in that its pivot is baked with its part having retaining means, in the first body of the tooth.
