Definitions

  • the present invention relates to a spectacle frame holder for a reproducing machine, known as a copier, capable of trimming a template or an ophthalmic lens under the control of a device comprising a feeler which recognizes the inner contour of the circles of a eyeglass frame.
  • the frame In such a device, the frame must be exactly immobilized between the strips, without play, but without deformation, and the systems known hitherto are not satisfactory in this regard.
  • the strips are biased towards each other by elastic means, that is to say a spring, the degree of tension of which depends on the size of the frame: if the force of the spring can provide an almost satisfactory tightening with midsize frames, this tightening can be insufficient with a small frame - thus leaving a play _ or may be too strong with a large frame _ risking deforming it.
  • elastic means that is to say a spring, the degree of tension of which depends on the size of the frame: if the force of the spring can provide an almost satisfactory tightening with midsize frames, this tightening can be insufficient with a small frame - thus leaving a play _ or may be too strong with a large frame _ risking deforming it.
  • the object of the invention is to remedy these drawbacks by providing a spectacle frame holder for a copying machine comprising an improved immobilization system for crimps.
  • a spectacle frame holder for a reproducing machine of the type comprising a base plate, two parallel strips slidably mounted on said plate so as to approach or move away from each other , and means for centering the frame between said strips, characterized in that the strips are fixed respectively on the opposite parallel strands of a cable forming a loop around two spaced pulleys, one of said pulleys constituting a member of cable drive and comprising braking means.
  • said braking means are adjustable and preferably comprises an elastic member urging said pulley axially in contact with a friction member.
  • the frame holder comprises, as known per se, a base plate 1 having four vertical supports 2, 3, 4, 5 arranged at the corners of a rectangle .
  • Two parallel bars 6, 7 connect the supports 2, 4 and the supports 3, 5 respectively, over the widths of the rectangle, the bars 6 and 7 being fixed on their respective supports at different heights in a vertical plane perpendicular to the plate 1, as shown in Figure 2.
  • a first strip 8 is slidably mounted on the bars 7 between the supports 2, 3 and 4, 5, and a second strip 9 is slidably mounted on the bars 6.
  • each strip may include a tubular boss 10, 11 respectively, surrounding one of the bars 6, 7, and forming a stop for the opposite strip.
  • a first pulley 12 is freely rotatably mounted on the support 2 by means of an axis 13
  • a second pulley 14 is rotatably mounted on the support 4 opposite the support 2, by means of an axis 15, and a cable 16 connects the pulleys 12, 14 and the strips 8, 9, as follows: a first end of the cable 16 is fixed to a finger 17 secured to the strip 9, the cable 16 then passing around the pulley 14 on which it is fixed by a screw 18, then extends to the strip 8 on which it is fixed by a screw 19, then passes around the pulley 12 to return to the finger 17 to which its other end is connected by the intermediate of a spring 20 whose sole function is to ensure a constant tension of the cable.
  • the axis 15 of the pulley 14 is fixedly mounted in the support 4 and the pulley 14 is constituted by a rotary cylinder around said axis and forming a control button ( Figure 3).
  • a nylon washer 21 is disposed between the support 4 and the adjacent end of the cylinder 14.
  • the latter has at its opposite end a counterbore 22 in which extends the end of the fixed axis 15, which is threaded .
  • a Belleville-type spring 23 is placed in the counterbore 22 around the axis 15 and is kept under compression by a nut 24.
  • This braking action is adjusted by means of the nut 24 so as to allow an easy manual drive but nevertheless offering sufficient resistance to maintain without play a mount M between the strips 8, 9.
  • the pulley 14 is driven by a geared motor device 25 of known type comprising a forward-reverse reverse-stop switch 26.
  • the frame holder according to the invention may include an oscillating support 27 articulated on the strip 8 (or 9), and a centering foot 28 fixed on the strip 9 (or 8).
