  • the difference between 29.83 seconds and 30 seconds is about 0.5% which could cause the poorly manufactured chronograph to make a rough approximation and strike three tens of seconds while the difference between 9 , 83 seconds and 10 seconds is about 2%, so a sufficient margin of error to ring "right" 9 seconds.
  • said safety device 100 of the applicant is a safety device without surprise 100 making it possible to strike the whole part of a number indicated by an indicator on a dial thanks to at least a first mobile 110, to at least a second mobile 120 and at least one actuating element 130, as can be seen on the figure 1 .
  • the figures 2A and 2B show, for their part, said at least one first mobile 110 mounted mobile on an axis 101, preferably mounted mobile in rotation about said axis 101, which allows said safety device 100 and at the same time said striking mechanism 200 d '' be more compact and better suited for repetitive movements such as chronographs for example.

  • said at least one first position 126 said at least one second mobile 120 is in contact with said at least one stop member 115, since as described above, said at least one stop member 115 drives said at least a second mobile 120, and when said at least one actuating element 130 acts on said at least one intermediate portion 123, said at least one second mobile 120 is moved towards said at least one second position 127, that is to say said at least one second mobile 120 is no longer in contact with said at least one stop member 115: in other words, said at least one actuating element 130 releases said at least one second mobile 120 from said at least one member stopper 115.
  • the kinematics which the figures 2A-2B and 3A-3B, shows how said at least one tooth 111, which has at least one surface and / or at least one dimension, is configured to move said at least one actuator 130 from said at least one first portion 121 towards said at least one intermediate portion 123, more particularly, how said at least one actuating element 130 is moved in contact with said at least one intermediate portion 123 so that it, i.e. said at least one actuating element 130, acts on said at least one intermediate portion 123 and releases said at least one second mobile 120 from said at least one stop member 115.
  • said at least one actuating element 130 slides and / or rubs, depending on the materials used, on said at least one first portion 121 which forces said at least one second mobile 120 to be in contact with said at least one stopper 115, and consequently, if said striking mechanism 200 is engaged, said at least one probe 230 will be in contact with said at least one distal portion 211.
  • said at least one actuating element 130 is configured to exert a force on said at least one second mobile 120 and preferably on said at least one first portion 121, on said at least one intermediate portion 123 and on said at least a second portion 122 and this said force is generated by the force of gravity and / or by a support force exerted by a return member and / or a drive member on said at least one actuating element 130, this which keeps said at least one actuating element 130 in contact with said at least one second mobile 120.
  • said at least one actuating element 130 When said at least one actuating element 130 is in contact with said at least one intermediate portion 123, the latter, that is to say said at least one intermediate portion 123 decomposes said force into a component radial to said axis 101 and a component perpendicular to the radial component so as to move said at least one intermediate portion 123 more rapidly than said at least one first meshed mobile 110 and thus allow said at least one second mobile 120 to disengage from said at least one stop member 115, and therefore, if said striking mechanism 200 is engaged, said at least one probe 230 will be in contact with said at least one proximal portion 212.
  • said at least one safety device 100 is associated with said at least one striking cam 210, when the user initiates said striking mechanism 200 of the chronograph at 29.83 seconds of the example described above, said at least one actuating element 130 will exert a force on said at least one first portion 121 and said at least one probe 230 will come into contact with said at least one distal portion 211 and more exactly at the end of said at least one distal portion 211 and will sound two tens of seconds or 9 seconds, depending on whether This is a feeler for the whole part of tens of seconds or the whole part of seconds and not 30 seconds.
  • said at least one actuating element 130 When the chronograph indicates 30 seconds, said at least one actuating element 130 will act on said at least one intermediate portion 123 and therefore said at least one second mobile 120 will be moved faster than said at least one first mobile 110 and consequently said at least one second mobile 120 will be released from said at least one stop member 115 which will make it possible to present said at least one proximal portion 212 of said at least one striking cam 210 of said striking mechanism 200 opposite said at least one probe 230 .
  • the whole part of said first number that is to say the minutes in this example, will be 1 and the part integer of said second number, again minutes, will be 2.
  • equations E03 and E02 the fractional part will be determined by equation E01. For example, if the chronograph indicates 29 minutes and 59 seconds, the equation E03 will give 1 quarter of an hour and the fractional part will be determined by the equations E01 which will give 14 minutes. The same goes for the seconds since E02 will give 5 tens of seconds and E01 will give 9 seconds. It follows therefore, that the integer part of the aforementioned first number is 1, 14, 5 and 9 according to the cam, and the integer part of the aforementioned second number is 2, 0, 0 and 0, again according to the cam.
