摘要:
An air shield is provided over a portal access opening between a vehicle access member and a stationary vehicle trim member. The vehicle access member provides access to a compartment of an interior of the vehicle. An air supply device is disposed within the vehicle. The air supply device is capable of producing a burst of air that discharges upon opening of the vehicle access member. An air concentrator device is in fluid communication with the air supply device. The air concentrator device outputs the burst of air that forms the air shield in a direction substantially transverse to the portal opening. The air shield is formed across at least a portion of a perimeter of the portal access opening between the vehicle access member and the stationary vehicle trim member. The air shield inhibits precipitation from entering the compartment of the vehicle during a pressure equalization phase that occurs in response to the opening of the vehicle access member.

A vent assembly is disposed within an interior space of a vehicle for opening and closing fluid communication between the interior space and an exterior of the vehicle. The vent assembly includes a housing defining a plurality of openings and a plurality of vanes disposed in the openings. An actuator mechanism moves the vanes between an open position and a closed position, and includes a shaped memory alloy (SMA) member for actuating the vanes between the open and closed positions. The SMA member is activated when a hatch of the vehicle is open to move the vanes into the open position and thereby open fluid communication between the interior space and the exterior to alleviate excessive air pressure buildup during closure of the hatch.

A device (10) is used to maintain climate conditions within an interior space (12) of a vehicle such as an ambulance (14). The device (10) includes a blower (18) to generate an air flow and a mounting plate (20) cooperating with a cover (29) to direct the air flow across an opening (16) into the interior space to form a wall of air to prevent loss of the climate conditioned air within the interior space. The vehicle could also be a food service truck, a people transport bus and a boat.

The rain and snow protection device is constructed so that rain cannot adhere to the window glass in the range of the field of vision; thereby a satisfactory field of vision is continuously visible without the use of wipers, through the window glass from the driver's seat in the motor vehicle, for example. The window glass can be protected so that rain cannot adhere to it, by providing on the outside of the vehicle, on the window frame 2 of the vehicle in which the lighting material 1 is inserted, one transparent rain protection plate 11 or a plurality of transparent rain protection plates 11, 12, 13 that face the lighting material 1 and are provided with the respective spaces 17, 17 to form thereby the rain protection slits 18, 18 at the leading edges 15, 15 of the rain protection plates 11, 12, 13; either of the side edges 14, 14 of these rain protection plates 11, 12, 13 is joined to either of the side sections 5, 5 of the window frame 2, or is attached so that moving tilting motion is possible; furthermore, the air 47, 47, blown out from the air jet nozzles 8, 8 provided at one location or a plurality of locations inside the vehicle, passes through the respective spaces 17, 17 and is blown out from the rain protection slits 18, 18.
摘要:
The invention relates to a vehicle for transporting products, comprising: a truck; a cargo space arranged on the truck for receiving the products during transport, with at least one access door; and an air curtain device close to the access door which, at least in the opened situation of the access door, generates an air curtain along a door opening of the access door, wherein the air curtain device comprises at least one fan, with an air feed duct which connects the fan to the exterior of the cargo space to supply outside air for the air curtain.
