Embodiment Construction

[0059] figure 1Shown is the structure of the movement train of a chronograph 33 according to the invention, in particular a wristwatch, with two rattrapante hands 23 , 25 arranged independently of each other. The chronograph hand support 3 supports the chronograph center hand 24 on the dial side. The chronograph center wheel 1 and the heart-shaped zero return controller 2 are fastened on the chronograph needle support 3 . The blocking cam 12 overlapping with the chronograph center wheel 1 and the zero return hammer rod 13 communicating with the heart-shaped zero return controller 2 are used to reset the chronograph center needle 24 . The chronograph hand support 3 is completely through and accommodates a first split-hand support 4 with a rattrapante wheel 8 which is in frictional connection with a first rattrapante hand 25 on the dial side. Pillar 3 supports rattrapante heart cam 5 below chronograph center wheel 1 in locked rotation.

Abstract

The chronograph (33) has a rotatably driven chronograph indicator shaft that is connected with a chronograph indicator (24). A rattrapante indicator shaft is arranged coaxial to the chronograph indicator shaft. The rattrapante indicator shaft is connected with a rattrapante indicator (23). The chronograph indicator and the rattrapante indicator are synchronously driven in an overlapping position. The rattrapante indicator shaft is rotatably locked independent of another rattrapante indicator shaft to display an intermediate period using the rattrapante indicator.

Description

technical field [0001] The present invention relates to timers. Background technique [0002] The relevant prior art includes, inter alia, chronographs with a rattrapante function. In this case, a rattrapante mechanism is often used to intermittently stop the chronograph hand during time measurement while the measurement process is still in progress, and then cause it to jump forward to the total measured time. For example to allow easy reading of the time elapsed at that moment (split time), while still continuing to record the total elapsed time. [0003] A chronograph with only one rattrapante hand is known from DE4209580A1. In this known chronograph, after starting, the chronograph hand and the rattrapante hand together can be stopped again by activating the first actuator. It is also possible to stop only the rattrapante hand by means of the second actuator, while the chronograph hand continues to run. This allows segmented time measurements within one minute. When...
