Definitions
- the present invention relates to a rotary computer with three scales and it relates more particularly to the structure of such a computer.
- the improvements which are the subject of the present invention aim to allow the production of a knitting calculator which responds better than hitherto to the various wishes of the practice.
- the computer under consideration is established by means of three elements molded from a hard plastic material so that they have a non-negligible thickness which makes them rigid and possibly allows scales to be etched on their upper face.
- the inner edge of the crown and the outer edge facing the central disc are shouldered to receive the ring which is provided with a lower rib engaging with play between the crown and the disc. so as to be assembled with a ring bearing under these elements in order to retain the ring with respect to these.
- the computer according to the invention shown in fig. l f which is assigned the general reference 1, is established by means of three elements, that is to say an outer crown 2, a cursor 3 in the form of a ring, and a central disc 4.
- the cursor 3 is slidably mounted relative to the other two elements so that in fact the three parts of the computer can move angularly with respect to each other after assembly.
- the inner edge of the crown 2 has an upwardly facing shoulder 2a, while similarly the outer edge of the central disc 4 is arranged to include a shoulder 4a symmetrically with respect to that 2a when the upper faces 2b, 4b of the crown and of the disc lie in the same plane.
- the cursor 3 which affects the shape of a ring has in cross section the shape of a T whose transverse branch 3a is provided with a thickness such that its two ends are placed with functional clearance against the shoulders 2a, 4a of the outer ring 2 and the central disc 4, its upper face then being in the same plane as those of the other two elements.
- the leg 3b of the slider 3 is then located between the inner and outer peripheries respectively of the outer ring 2 and the central disc 4.
- the height of this leg is equal to the thickness of the residual part of the inner and outer edges of the crown and the disc; that is to say that of the parts of the two elements located below the two shoulders 2a, 4a. In this way, the ring-shaped cursor 3 is flush with the upper and lower faces of the outer ring 2 and of the central disc 4.
- the assembly of the three parts in question takes place at by means of a flat ring 5 which is associated with the end face of the leg 3b for example by means of studs 3c secured to the cursor 3 and which forcefully engage in perforations 5a of the ring in order to maintain the crown 2 and disk 4 with respect to said cursor.
- the ends of the studs 3c could if desired be riveted relative to the ring 5.
- the central disc 4 In order to lighten the central disc 4, its center is provided with a recess 4c made on its inner face. Similarly, the outer ring 2 has an annular depression 2c.
- a heel 2d oriented downwards and whose height is such that its base is located at least in the plane containing the projection la lower of the other elements.
- the graduations 2e, 3d, 4d carried respectively by the crown, the ring and the central disc can be engraved in the upper face of these three elements so that they cannot be erased by the friction of the fingers of the user. .
- the central disk 4 is also provided with a 4th opening provided square.
- This opening or window is used in a known manner to count the number of stitches and rows obtained on a knitting sample, the basic dimensions of which must be modified as a function of the size of the wool as is well known in conventional calculators.
- An additional advantage of the computer established in accordance with the invention therefore consists in considerably reducing the size compared to conventional computers whose opening or window is offset outside the crown.

Abstract
Description
La présente invention est relative à un calculateur rotatif à trois échelles et elle vise plus particulièrement la structure d'un tel calculateur.The present invention relates to a rotary computer with three scales and it relates more particularly to the structure of such a computer.
Il existe dans le commerce des dispositifs du genre en question réalisés au moyen de trois disques découpés dans une feuille de matière plastique ou analogue et assemblés de manière pivotante par l'intermédiaire d'un rivet central. On comprend aisément que les disques ainsi réalisés sont dépourvus de rigidité et qu'en conséquence ils sont relativement fragiles.There are commercially available devices of the kind in question produced by means of three discs cut from a sheet of plastic material or the like and assembled pivotally by means of a central rivet. It is easy to understand that the discs thus produced are devoid of rigidity and that consequently they are relatively fragile.
Les perfectionnements qui font l'objet de présente invention visent à permettre la réalisation d'un calculateur pour tricotage qui réponde mieux que jusqu'à présent aux divers desiderata de la pratique.The improvements which are the subject of the present invention aim to allow the production of a knitting calculator which responds better than hitherto to the various wishes of the practice.
Suivant l'invention le calculateur considéré est établi au moyen de trois éléments moulés en une matière plastique dure de telle sorte qu'ils présentent une épaisseur non négligeable qui les rend rigides et permet éventuellement que des échelles soient gravées en creux sur leur face supérieure.According to the invention, the computer under consideration is established by means of three elements molded from a hard plastic material so that they have a non-negligible thickness which makes them rigid and possibly allows scales to be etched on their upper face.
A cet effet l'arête intérieure de la couronne et l'arête extérieure en vis-à-vis du disque central sont épaulées pour recevoir l'anneau qui est pourvu d'une nervure inférieure s'engageant avec jeu entre la couronne et le disque de manière à être assemblée à une bague portant sous ces éléments afin de retenir l'anneau par rapport à ceux-ci.To this end, the inner edge of the crown and the outer edge facing the central disc are shouldered to receive the ring which is provided with a lower rib engaging with play between the crown and the disc. so as to be assembled with a ring bearing under these elements in order to retain the ring with respect to these.
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :
- Fig. 1 est une vue en perspective d'un calculateur rotatif pour tricotage établi conformément à l'invention.
- Fig. 2 en est une coupe suivant II-II fig. 1.
- Fig. 3 est une vue semblable à celle de fig. 2 mais représentée avec les différents éléments séparés les uns des autres.
- Fig. 1 is a perspective view of a rotary computer for knitting established in accordance with the invention.
- Fig. 2 is a section along II-II fig. 1.
- Fig. 3 is a view similar to that of FIG. 2 but shown with the different elements separated from each other.
Le calculateur suivant l'invention représenté en fig. lf qui est affecté de la référence générale 1, est établi au moyen de trois éléments, d'est-à-dire une couronne extérieure 2, un curseur 3 en forme d'anneau, et un disque central 4. Le curseur 3 est monté coulissant par rapport auxdeux autres éléments de telle sorte qu'en fait les trois parties du calculateur peuvent se déplacer angulairement les unes par rapport aux autres après assemblage.The computer according to the invention shown in fig. l f which is assigned the
Comme illustré en fig. 2 et 3, l'arête intérieure de la couronne 2 comporte un épaulement 2a orienté vers le haut, tandis que de manière semblable l'arête extérieure du disque central 4 est agencée afin de comprendre un épaulement 4a symétriquement par rapport à celui 2a lorsque les faces supérieures 2b, 4b de la couronne et du disque se trouvent dans un même plan.As illustrated in fig. 2 and 3, the inner edge of the
Le curseur 3 qui affecte la forme d'un anneau présente en section transversale la forme d'un T dont la branche transversale 3a est prévue d'une épaisseur telle que ses deux extrémités viennent se placer avec jeu fonctionnel contre les épaulements 2a, 4a de la couronne extérieure 2 et du disque central 4, sa face supérieure se trouvant alors dans le même plan que celles des deux autres éléments. La jambe 3b du curseur 3 est alors située entre les périphéries intérieure et extérieure respectivement de la couronne extérieure 2 et du disque central 4. Bien entendu la hauteur de cette jambe est égale à l'épaisseur de la partie résiduelle des bords intérieur et extérieur de la couronne et du disque;c'est-à-dire celle des parties des deux éléments situés en dessous des deux épaulements 2a, 4a. De cette manière le curseur 3 en forme d'anneau affleure les faces supérieure et inférieure de la couronne, extérieure 2 et du disque central 4.The
L'assemblage des trois pièces en question s'effectue au moyen d'une bague plate 5 qu'on associe à la face extrême de la jambe 3b par exemple au moyen de goujons 3c solidaires du curseur 3 et qui s'engagent à force dans des perforations 5a de la bague en vue de maintenir la couronne 2 et le disque 4 par rapport audit curseur. Les extrémités des goujons 3c pourraient si désiré être rivées par rapport à la bague 5.The assembly of the three parts in question takes place at by means of a
En vue d'alléger le disque central 4, son centre est muni d'un chambrage 4c pratiqué sur sa face intérieure. De même la couronne extérieure 2 comporte une dépression annulaire 2c. De manière que le calculateur rotatif 1 soit stable sur un plan horizontal on ménage sur le pourtour de sa couronne extérieure 2 un talon 2d orienté vers le bas et dont la hauteur est telle que sa base est située au moins dans le plan contenant la saillie la plus basse des autres éléments.In order to lighten the
Les graduations 2e, 3d, 4d portées respectivement par la couronne, l'anneau et le disque central peuvent être gravées dans la face supérieure de ces trois éléments de manière qu'elles ne puissent pas être effacées par le frottement des doigts de l'utilisateur.The
Le disque central 4 est encore pourvu d'une ouverture 4e prévue carrée. Cette ouverture ou fenêtre est utilisée de manière connue pour compter le nombre de mailles et de rangs obtenus sur un échantillon de tricot dont les dimensions de base doivent être modifiées en fonction de la grosseur de la laine comme cela est bien connu dans les calculateurs usuels.The
Un avantage supplémentaire du calculateur établi conformément à l'invention consiste donc à réduire considérablement l'encombrement par rapport aux calculateurs usuels dont l'ouverture ou fenêtre est décalée à l'extérieur de la couronne.An additional advantage of the computer established in accordance with the invention therefore consists in considerably reducing the size compared to conventional computers whose opening or window is offset outside the crown.
On a ainsi réalisé un calculateur pour.tricotage qui est robuste et dont la manipulation est aisée du fait que l'on peut choisir facilement le serrage du curseur par rapport à la couronne extérieure et au disque central.We thus realized a calculator for knitting which is robust and whose handling is easy because we can easily choose the tightening of the cursor relative to the outer crown and to the central disc.
Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant lès détails d'exécution décrits par tous autres équivalents.It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the details of execution described by all other equivalents.
