Abstract
A ventilating device for personnel-carrying motor vehicles, more particularly combat vehicles, ambulances, command vehicles, has a dust filter (2), a fine-mesh filter (3), upstream of an air distributor (4), a shutter (7), operable from the crew area for preventing air entering the distributor (4), and at least one connector (8), equipped with a valve (12), for the connection of a protective breathing mask, the valve (12) opening when the wearer of the mask inhales. <IMAGE>
Description
SPECIFICATION
Ventilating device for personnel-carrying motor vehicles
This invention relates to a ventilating device for personnel-carrying motor vehicles, such as combat vehicles, ambulances and command vehicles.
The crews of such vehicles must be provided with respiratory air purified of contaminants even when the airtightness of the vehicle is no longer sufficient to maintain the positive pressure necessary to prevent contaminated air from entering through non-airtight regions, or when the air supplying arrangement is no longer supplied with sufficient power or is damaged.
A known ventilating device for personnel-carrying motor vehicles, more particularly cambat vehicles, ambulances, command vehicles or the like, is described in German Auslegeschrift No. 1,165,434. This device has an air supplying arrangement and an air purifying arrangement consisting of a dust filter and a fine-mesh filter. The device draws in surrounding air and blows it into the interior of the vehicle. This is effected eitherthrough a compression pipe joint of an air distibutor or through an outlet from the fine-mesh filter. Means for the direct connection of protective breathing masks or other mouth pieces for the personnel are not provided.
According to the present invention, there is provided a ventilating device for supplying air from the exterior of a personnel-carrying motor vehicle to the interior of the vehicle, the ventilating device comprising a dust filter and a fine-mesh filter for filtering incoming air and distribution device for distributing the filtered incoming air into the interior of the vehicle, the ventilating device being provided with a closure means, operable from within the interior of the vehicle, for preventing filtered air from entering the distribution device and with at least one connector, downstream of the filters, for the supply of the filtered incoming air to a protective breathing mask, the connector being provided with a valve which opens when the wearer of the mask inhales.
Preferably, an adaptor is fitted to the distribution device, the adaptor being provided with at least one connector for the supply of the filtered incoming air to a protective breathing mask when the closure means is open, the connector being provided with a valve which opens when the wearer of the mask inhales.
Thus, the present invention provides the possibility of connecting protective breathing masks, by means of which the personnel can supply themselves with air both in the case of the air distributor failing and also in the case of the personnel area becoming non-airtight (and therefore of the positive pressure falling).
It is possible for the crew to supply themselves with uncontaminated respiratory air in a simple and safe way if the ventilating device fails or if it fails to be effective in the personnel area due to lack of airtightness. The connectors on the fine filter housing enable the connection hoses of protective breathing masks to be connected to the ventilating device. The shutter and the inhalation valves in the connectors regulate the supply of respiratory air, which is easily inhaled by the users.
The adapter is easy to fit onto a compression pipe joint of the air distributor. Pure respiratory air is supplied to the user.
For a better understanding of the invention, reference will now be made, by way of example, to the accompanying drawings in which;
Figure lisa sectional view of a ventilating device of the invention;
Figure 2 is an end view of the device of Figure 1; and
Figure 3 shows the ventilating device of Figure 1, fitted with an adaptor.
The ventilating device 1 shown in the Figures is housed in the crew area of a vehicle. The device contains a dust filter 2 as a preliminary filter and a fine-mesh filter 3 in fluid communication with the dust filter 2. An air distributor 4 is connected downstream of the fine-mesh filter 3. The air to be purified enters from outside through a connector 5 and, after being filtered by the filters 2 and 3, leaves the ventilating device 1 through a compression pipe joint 6 on the air distributor 4.
The fine-mesh filter 3 has a closure shutter 7 which can be operated from within the crew area by means of an operating lever 13 movable from the position shown in solid lines in Figure 2 (shutter 7 closed) to the position shown in dotted lines in Figure 2 (shutter 7 open). The shutter 7 is located upstream of an opening leading to the air distributor 4. Connectors 8, which are provided with self-closing inhalation valves 12 which open during inhalation, connect protective breathing masks 9 to the device so that purified air can be supplied to the masks 9. If the air distributor 4 fails, and if the protective breathing masks 9 are connected to the connectors 8 and the opening to the air distributor 4 is closed by means of the shutter 7, it is possible for the crew to supply themselves with purified respiratory air.
Figure 3 shows the ventilating device wherein the shutter 7 is open (and consequently not shown in the
Figure) and wherein the compression pipe joint 6 of the air distributor 4 is provided with an adapter 11 for the connection of protective breathing masks 9.
The adapter 11 has connectors 14 for this purpose, these connectors being provided with valves 12 as described above. The adaptor 11 is used when the positive pressure in the crew area has fallen as a result of a loss of airtightness.
1. A ventilating device for supplying air from the exterior of a personnel-carrying motor vehicle to the interior of the vehicle, the ventilating device comprising a dust filter and a fine-mesh filter for filtering incoming air and a distribution device for distributing the filtered incoming air into the interior of the vehicle, the ventilating device being provided with a closure means, operable from within the interior of the vehicle, for preventing filtered air from entering the distribution device and with at least one connector, downstream of the filters, for the supply of the
