Description
(54) ЗАЩИТНАЯ КАСКА Изобретение относитс к средствам индивидуальной защиты от Механического воз; действи и может быть использовано в горнорудной промышленности. Известна защитна каска, содержаща корпус и внутреннюю предохранительную осиастку 1. Однако известна каска может предохранить голову от травм, вызванных попаданием только небольшой величины и т жести отколов, что говорит о низкой эффективности защиты с помощью известной |саски .; Цель изобретени - повышение эффективности защиты. Указанна цель достигаетс тем, что защитна каска, содержаща корпус и внутреннюю предохранительную оснастку, имеет закрепленный над ее корпусом подпружиненный щиток в виде полусферы с подвижными электродамн и прокладкой, а корпус каски имеет гнезда с неподвижными кон-тактнымн элементами, расположенными напротив электродов щитка, реле, источник питани и сигнальное устройство, причем выводы электродов щитка и контактных элементов корпуса св заны посредством реле и источника питанн с сигнальным устройством . На фиг. i изображена защитна каска, общий вид; иа фнг. 2 - блок-схема сигнального устройства. Защитна каска (фиг. I) содержит корпус 1, внутреннюю оснастку 2, над корпусом установлен подпружинеииый щиток 3 с упругой прокладкой 4 и подвижными элект родамн 5, упорно-возвратные пружины 6 дл удерживани щитка в исходном положении . Корпус каски имеет гнезда 7 с неподвижными контактными элементами 8. Подвижные контакты 5 имеют возможность двигатьс в гнездах 7, в которых нзолнроваио от корпуса каски встроены непбдвижные контактные элементы, и соединены последовательно посредством контактов 8 и нсточннком 10 питани сигнальным устройством П. Работа устройства осуществл етс следующим образом. При падении на каску т желого откола, например в щахте, в результате чего р очки может потер ть сознание, щиток д пускаетс , настолько, что подвижные ко (54) SECURITY DRAWINGS The invention relates to personal protective equipment against mechanical cargo; action and can be used in the mining industry. The protective helmet is known, which includes the body and the inner safety axle axle 1. However, the known helmet can protect the head from injury caused by hitting only a small amount and the weight of the spalling, which indicates a low effectiveness of protection with the well-known saska; The purpose of the invention is to increase the effectiveness of protection. This goal is achieved by the fact that the protective helmet containing the body and the internal safety equipment has a spring-loaded hemisphere-shaped shield mounted on its body in the form of a hemisphere with moving electrodes and a gasket, and the helmet body has slots with fixed contact elements located opposite the shield electrodes, a relay , a power source and a signaling device, and the terminals of the plate electrodes and contact elements of the housing are connected by means of a relay and a power source to the signaling device. FIG. i shows a protective helmet, general view; Ia fng. 2 is a block diagram of a signaling device. The protective helmet (Fig. I) contains a body 1, an internal snap 2, a spring-loaded shield 3 with an elastic gasket 4 and movable electrodes 5, and return-stop springs 6 for holding the shield in the initial position are installed above the case. The helmet body has slots 7 with fixed contact elements 8. Movable contacts 5 have the ability to move in slots 7 in which non-movable contact elements are embedded from the helmet body, and are connected in series by means of contacts 8 and supply signal 10 of the device. in the following way. When a heavy splitting off on a helmet, for example, in a shift, as a result of which the p glasses may faint, the flap d is allowed so that
