    • Pyrotechnic signaling means (10) are ignited manually by pulling on a pulling member (24). In known pyrotechnic signaling means (10), the pulling member (24) has a short cable which is knotted to an operating means (26). A knot such as this can be produced only manually, thus making the production of pyrotechnic signaling means (10) quite complex. In addition, an ignition device (14) for known pyrotechnic signaling means (10) has a hole through it for a firing bolt (36) which is connected to the pulling member (24). This allows moisture to enter the pyrotechnic signaling means (10) through the ignition device (14). The pyrotechnic signaling means (10) according to the invention provides for the pulling member (24) to be formed from flexible strip-like sections (48, 50), which are connected by film hinges (54) and can be collapsed, saving space, when not in use. The sections (48, 50) can be integrally connected to an operating means (46), such that the entire pulling member (24) can be formed integrally from plastic and manual fitting of the individual components of the pulling member (24) is superfluous. The invention also provides for the ignition device (14) to be sealed by a coupling device (42) of the pulling member (24) until the pyrotechnic signaling means (10) are activated. This means that no moisture can pass through the ignition device (14) before the pyrotechnic signaling means (10) are activated.
    • 通过拉动拉动构件(24)来手动点火烟火信号装置(10)。 在已知的烟火信号装置(10)中,牵引构件(24)具有打结到操作装置(26)的短电缆。 这样的结可以仅仅手工制造,从而使烟火信号装置(10)的生产相当复杂。 此外,用于已知烟火信号装置(10)的点火装置(14)具有穿过其的孔,用于连接到拉动构件(24)的击发螺栓(36)。 这允许湿气通过点火装置(14)进入烟火信号装置(10)。 根据本发明的烟火信号装置(10)提供了由柔性条状部分(48,50)形成的拉动构件(24),该部分通过膜铰链(54)连接并且可以折叠,从而节省了空间 ,不用时。 这些部分(48,50)可以一体地连接到操作装置(46),使得整个牵引构件(24)可以由塑料一体地形成,并且拉动构件(24)的各个部件的手动装配是多余的 。 本发明还提供点火装置(14)由拉动构件(24)的联接装置(42)密封,直到烟火信号装置(10)被启动为止。 这意味着在烟火信号装置(10)被激活之前,没有水分可以通过点火装置(14)。
