Предлагаема  откидна  задвижка представл ет бесшумный затвор, не требующий дл  запирани  двери применени  сильного удара.The proposed flap is a silent shutter that does not require a bang to lock the door.

На чертеже изображен вид задвижки спереди.The drawing shows a front view of the valve.

Предлагаема  откидна  задвижка А удерживаетс  в запертом положении пружин щим стержнем Г, подвижно прикрепленным к створке двери. В тот момент, когда дверь плотно закрываетс , конец стержн  Г упираетс  в крюк , отчего, при дальнейшем движении дверной створки, задвижка А соскакивает со штыр  В прикрепленного к стержню Г и падает в крюк Б. Удержание задвижки Л в открытом положении производитс  тем же приспособлением между упором Е и штырем В.The proposed flap A is held in the locked position by a spring rod G movably attached to the door leaf. At that moment, when the door is tightly closed, the end of the rod G rests on the hook, which causes the valve A to slide off the pin B attached to the rod D when the door leaf moves further and falls into hook B. Holding the valve L in the open position is made by the same device between stop E and pin B.

При открывании двери, когда задвижка А бывает подн та, пружина Л возвращает стержень Р в то положение, при котором штырь В подпирает задвижку А.When the door is opened, when the valve A is raised, the spring L returns the rod P to the position at which pin B supports the valve A.
