Description

С другой стороны крышка 1 посредством рычагов 3, 4 шарнирно св зана с экраном 12, установленным в нроеме а люка. В нишах 13 экрана смонтированы на ос х 14 подпружиненные пружинами 15 ручки 11.On the other hand, the lid 1 by means of the levers 3, 4 is hingedly connected with the screen 12 mounted in the hatch. In the niches 13 of the screen are mounted on the axis x 14 spring-loaded springs 15 knobs 11.

Дл уплотнени крышки 1 и экрана 12 относительно окантовки 2 проема она снабжена уплотн ющими профил ми 16 и 17.To seal the cover 1 and the screen 12 relative to the border 2 of the opening, it is provided with sealing profiles 16 and 17.

Дл открыти вентил ционного люка необходимо , преодолева усилие пружин 15, переместить в осевом направлении соответствующую пару ручек 11 до выхода штырей 8 из гнезд 7 пластин 6, после чего перевести ручки 11 вниз, которые, воздейству на шарнирно св занные между собой и подпружиненные рычаги 3, 4, обеспечивают открывание смежной с ними стороны крышки люка. Одновременно с открытием крышки люка под воздействием рычагов 3 и 4 происходит синхронное опускание смежной с ними стоооны экрана.To open the vent, it is necessary, overcoming the force of the springs 15, to move in the axial direction the corresponding pair of knobs 11 until the pins 8 come out of the slots 7 of the plates 6, and then move the knobs 11 down, which will affect the hinged and spring-loaded levers 3 , 4, provide opening of the adjacent side of the hatch cover. Simultaneously with the opening of the hatch cover under the influence of the levers 3 and 4, the adjacent screen is synchronously lowered.

Фиксаци крышки люка и экрана 12 в любом из возможны.к открытых и закрытом положени х осуществл етс за счет входа штырей 8 в гнезда 7 под действием усили сжати пружин 15.The hatch cover and screen 12 are fixed in any of the possible ways. By the open and closed positions, the pins 8 are inserted into the slots 7 by the force of compression of the springs 15.

При открытом люке стру воздуха, попада под крышку, отражаетс от нее, направл етс на экран 12 и, отража сь от последнего , измен ет свое направление и рассеиваетс .When the hatch is open, the stream of air, falling under the lid, is reflected from it, directed to the screen 12 and, reflecting from the latter, changes its direction and dissipates.

Claims

1. A vehicle's ventilation hatch containing a lid installed in its opening associated with spring-loaded levers connected to the fringing of the opening and controlled by handles, characterized in that in order to provide the possibility of stepwise adjustment

the inflow of air into the vehicle's interior, it is equipped with shitters, hingedly connected to each other and with the lid and controlled independently of one another, and rigidly fixed along the edge of the hatch opening

plates made with vertically spaced nests to interact with the pins.

2. A ventilation hatch according to claim 1, characterized in that, in order to dissipate the jet of air entering the passenger compartment, a screen is installed in the opening of the hatch, pivotally connected by means of levers to the cover.

3. Ventilation hatch on the PP. 1 and 2, characterized in that, in order to provide

the possibility of tilting the hatch against the transverse axis of the vehicle when opening the hatch, the free ends of the pins are tapered, and the slots for the pins have the surface of the bodies of rotation with

the inclination of the generatrix, the inverse of the taper of the pin.
