Definitions

  • the present invention relates to a rotary computer with three scales and it relates more particularly to the structure of such a computer.
  • a rotary computer with three scales and it relates more particularly to the structure of such a computer.
  • 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 easily understood that the discs thus produced are devoid of rigidity and that consequently they are relatively fragile.
  • Document FR-A-2192339 also discloses a rotary computer comprising a crown, a ring-shaped cursor and a central disc, these three elements being provided with graduations suitable for carrying out calculations.
  • 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 rib engaging with clearance between the crown and the disc.
  • this calculator does not allow calculations concerning the number of stitches and the number of rows of a knitted fabric.
  • the structure of the ring according to the invention is different.
  • the improvements which are the subject of the present invention aim to allow the production of a knitting calculator which responds better than so far 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 each provided with a shoulder turned upward to receive the ring which, in cross section, has the shape of a T, the leg of which constitutes a lower rib engaging with clearance 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. 1, 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 relative to one another 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 cursor 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 is carried out 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 integral with the slider 3 and which forcefully engage in perforations 5a of the ring in order to maintain the crown 2 and the disc 4 relative 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 according to 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.
  • a knitting calculator has thus been produced which is robust and easy to handle because it is easy to choose the tightening of the slider relative to the outer crown and to the central disc.
