Изобретение относитс к медицинской технике , а именно к средствам индивидуальной защиты от шума.The invention relates to medical technology, in particular to means of individual protection against noise.
Известно устройство дл креплени противошумных наушников к защитной каске, содержащее наушники, установленные на держател х , перемещаемые на зажимах по высоте «и вращаемые на фиксируемых блоках, а также регулирующие элементы прижима наушников к ушам, определ ющие силу прижати .A device for attaching antinoise headphones to a protective helmet is known, comprising headphones mounted on holders that are moved on clamps in height and rotated on fixed blocks, as well as regulating elements of pressing the headphones to the ears, which determine the pressing force.
С целью обеспечени регулировани прижати наушников с фиксацией в каждом положении предложено держатели выполнить в виде Г-образных кронштейнов с вмонтированными в них шпилька ми н Т-образным хвостовиком , а пружины - с продольным пазом .In order to ensure that the headphones are adjusted with fixation in each position, holders are proposed to be designed in the form of L-shaped brackets with studs mounted in them with a T-shaped shank, and springs with a longitudinal groove.
На фиг. 1 изображено описываемое устройство , продольный разрез; на фиг. 2 - вид по стрелке А на фиг. 1.FIG. 1 shows the described device, a longitudinal section; in fig. 2 is a view along arrow A in FIG. one.
Устройство содержит держатели, выполненные в виде Г-образных кронштейнов 1 с вмонтированными в них шпильками 2 и Т-образным хвостовиком 3 и пружины 4, выполненные с продольным пазом.The device comprises holders made in the form of L-shaped brackets 1 with studs 2 mounted in them and a T-shaped shaft 3 and springs 4, made with a longitudinal groove.
Устройство используетс следующим образом . Пружину 4 через продольный паз надевают на Т-образный хвостовик 3 держател и шейку фигурной гайки 5. Они удерживают пружину и одновременно вл ютс направл ющими при ее продольном перемещении. При отвинчивании фигурной гайки 5 отжимаетс верхн часть пружины 4 от каски 6, пружина поворачиваетс в пазе держател и ее нижн часть поджимает наушник 7 к голове. Сила прижати зависит от положени фигурной гайки. При обратном движении гайки пружина освобождаетс , и наушник отходит от головы. Регулировка наушника по высоте осуществл етс путем перемещени пружины вверх пли вниз на величину паза в пружине.The device is used as follows. The spring 4 is put on the T-shaped shank 3 of the holder and the neck of the figure nut 5 through the longitudinal groove. They hold the spring and at the same time act as guides during its longitudinal movement. When unscrewing the figure nut 5, the upper part of the spring 4 is pressed from the helmet 6, the spring rotates in the holder groove and its lower part presses the earphone 7 to the head. The clamping force depends on the position of the cam nut. When the nut moves backward, the spring is released, and the earphone moves away from the head. The height adjustment of the earpiece is made by moving the spring up or down by the amount of the slot in the spring.
Предмет изобретени Subject invention
Устройство дл креплени противошумных наушников к защитной каске, содержащее два наушника, укрепленных на ирул-синах, и два держател с обеих сторон каски, отличаюшеес тем, что, с целью обеспечени регулировани прижати наушников с фиксацией в каждом положении, держатели выполнены в виде Г-образных кронштейнов с вмонтированными в них шпильками и Т-образным хвостовиком, а пружины - с продольным пазом.A device for attaching anti-noise headphones to a protective helmet containing two headphones fixed on the wheel and two holders on both sides of the helmet, characterized in that, in order to ensure that the headphones are adjusted with fixation in each position, the holders are in the form of shaped brackets with studs mounted in them and a T-shaped shank, and springs with a longitudinal groove.
