<p>The gear train(10,12,14,18) transmits a rotating movement from the shaft of a first wheel(10) to the shaft of a second wheel(18) attached to which is a piece(30) which turns against the effect of a spring(32). The piece(30) is designed to be latched in a first `armed' position by a retaining means. At least three successive toothed gears(12,14,18), whose teeth interlink, have their axes parallel and at least two axes are set at an angle( alpha ) between 10 and 180 degrees. The rotational axis(15) of the median gear(14) is slotted along the angles bisector . The play between the teeth and the axis of rotation slot(15) of the gear(14) is between 1.4 and 2/3 the height of the teeth.</p> |
