Definitions

  • the invention relates to a chronograph with a clockwork of the one second chronograph hand and in a number in particular of thirty steps per turn a minute chronograph hand are rotatably driven, with a control device for stopping the second chronograph hand and the minute chronograph hand as well for starting a slave pointer mechanism of a second towing pointer and a minute towing hand, which is a triggering element to start and stop the second-hand pointer and of a minute towing.
  • the object of the invention is therefore a chronograph of the aforementioned To create kind, which has few simple components, a small one Required space and has a high reliability.
  • the drag indicator mechanism a common trigger element for the second-hand pointer and the minute toe pointer, from which a catch in a recess on the circumference of a minute towing pointer wheel evenly distributed locking recesses latched and ausrastbar is controllable, with the minute towing pointer wheel connected to a minute-hand pointer tube of a minute-hand pointer is and the number of recesses the number of steps of the minute chronograph hand per revolution.
  • the common trigger element for the second toes and The minute-hand pointer ensures that starting and stopping of Second hand and minute hand simultaneously.
  • the minute-hand pointer For easy synchronization of the minute-hand pointer with the minute chronograph hand can the minute-hand pointer over a Minute toe heart lever with a minute toe pointer heart be coupled, the rotation with a pointer axis of the minute chronograph hand connected is.
  • the minute toe pointer heart lever can with one end to the minute-hand pointer wheel pivotally mounted about an axis parallel to the axis of rotation and with its other end by a spring force in contact with the minute toes pointer heart be charged.
  • the minute toe hand lever is from one on the minute hand pointer wheel fastened spring element against the minute toe pointer heart acted upon, so this spring element is always in his Correct position to the minute towing hand lever carried.
  • the minute-hand pointer lever can be used by an actuatable by the triggering element Entkupplungs adopted disengaged from the minute toe pointer heart be.
  • the isolator wheel can drive safely through the isolator lever with a radially encircling toothing, in particular a saw tooth and the isolator lever with a corresponding Be provided counter teeth, which in the Einkuppel ein in the toothing of the isolator wheel engages.
  • the uncoupling device is preferably one Control lever operable by the triggering element from a Einkuppel ein in a Entkuppelgna against a spring force to one Control lever axis is pivotally driven, wherein the isolator lever of the control lever against the spring force is pivotally acted upon.
  • control lever In multiple function and thus parts and space saving the control lever have a stop by which the catch in the Einkuppel ein the control lever from the latching recess acted unlatched is.
  • control lever In its uncoupling position the control lever in its Einkuppelgna on a stop, in particular a stop eccentric in plant.
  • control lever of the columns from its Einkuppel ein be pivotally drivable in its Entkuppel too.
  • the column wheel is preferably radially distributed with evenly distributed arranged switching teeth of double number than the number of Ko-Ionnen formed, via which the column wheel is rotatably driven, wherein to secure the positions of the column wheel a detent spring in the Tooth gaps between the shift teeth can be resiliently latched.
  • the illustrated part of the slave pointer mechanism shows by a not shown pusher rotatably actuated Column 1 with eight axially projecting, evenly distributed distributed Columns 2 and sixteen evenly distributed around the circumference arranged Switching teeth 3.
  • a detent 5 of a detent spring 6 is resiliently engaged.
  • a finger 7 of a pivotable about a control lever axis 8 Control lever 9 engages in the gaps 10 between the columns 2 and is ramped by turning the column wheel 1 in a clockwise direction lifted out of a gap 10 and slides on the outer periphery the column 2 until it falls into the following gap 10 again.
  • control lever 9 For positioning the Entkuppel too the control lever 9 is located with a Stop arm 11 to a stopper eccentric 12 and is by a arranged in one piece on the control lever 9, supported on a pin 13 Spring arm 14 spring-loaded against the stop eccentric 12.
  • the control lever 9 further comprises an actuating arm 15, on whose free end region is a stop 16, through which a with an end fixedly arranged spring arm 17 deflectable acted upon is that carries a catch 18 at its free end.
  • the control lever 9 further has on its actuating arm 15 a Extension 19, by the pivoting of the control lever 9 from his Entkuppel ein in its Einkuppel ein one to one to the control lever axis 8 parallel insulator axis 20 pivotable isolator lever 21 opposite the force of a spring 22 from its Einkuppel ein (Figure 1) in its Auskuppel ein ( Figure 2) is pivotally acted upon.
  • the isolator lever 21 has a radially spaced from the insulator axis 20 Area three teeth of a counter-toothing 23, the pivoting the isolator lever 21 from the uncoupling in the Einkuppel ein in a radially encircling saw toothing 24 of an isolator wheel 25 intervene and this by a certain angle of rotation turn clockwise.
  • the isolator 25 is about a parallel to the control lever axis 8 axis of rotation 26 rotatably mounted and carries a stop 27 through which a minute towing heart lever 28 upon rotation of the isolator wheel 25 by one to the axis of rotation 26 parallel axis 29 is pivotally acted upon.
  • the minute toe lever 28 is at one end to the Axis 29 pivotally mounted on a minute-hand pointer wheel 30, which is also rotatably mounted about the rotation axis 26, and acted upon with its other end the radially encircling heart cam 31 of a Minute toes pointer heart 32.
  • This minute towing pointer heart is 32 likewise rotatable about the axis of rotation 26 and with a not shown, the hand axis of a minute chronograph hand bearing minute counter wheel a chronograph firmly connected.
  • the minute-hand pointer wheel 30 has on its radially circumferential circumference evenly distributed thirty recesses 34, which correspond in shape to the shape of the catch 18 and in which the catch 18 can be latched.
  • the chronograph has a second chronograph hand, not shown and a minute chronograph hand, wherein the minute chronograph hand rotatable in thirty steps per revolution is.
  • the second chronograph hand is a seconds drag pointer and the minute chronograph hand is also in assigned to thirty steps per revolution of indexable minute-hand pointers.
  • the slave pointer mechanism of both slave hands has the column wheel 1 as a common trigger element.
  • the column wheel 1 is a Tooth pitch of the switching teeth 3 further rotated. This results in a ramp-like Disengaging the finger 7 from the gap between two columns 2 and resting on the peripheral outer surface of a column. 2
  • the control lever 9 is pivoted clockwise, which pivots about the stop 16 of the spring arm 17 and its catch 18 is lifted out of the recess 34.
  • the isolator 25 with only the specific swing angle move its abutment 27 away from the minute-hand pointer heart lever 28 can, this movement is by a stop 36 of the minute towing pointer wheel 30 bordered.
