Abstract
An apparatus for ventilating high speed elevator cars during the travel with closed doors includes upper and lower ventilation systems having primary air openings formed in troughs located in the upper and lower portions of the car body. The pressure of the incoming air is relieved and the air is smoothed in steps in air chambers and air channels such that the air flows free of drafts and noiselessly into the interior of the car. The ventilation of the elevator car takes place through the ventilation apparatus in the direction of travel of the car, since both the ventilation systems provide flow through in both directions of travel of the car.
Claims17
An apparatus for the ventilation of high speed elevator cars in which ventilation of the car interior during the travel with closed doors takes place through a plurality of openings of total predetermined cross-sectional area formed in the upper and lower portions of the car body and wherein a vertical air current flows in the car and is produced by slip stream and pressure build-up at the air-displacing car, comprising:
- an upper ventilation system located in an upper portion of an elevator car and a lower ventilation system located in a lower portion of the car, each said ventilation system permitting air to enter the car and for decelerating and pressure relieving an entering air current during the travel of the car in an associated direction and including a plurality of primary air openings formed in at least one side of the car, means forming an air chamber connected to said primary air openings, means forming secondary air openings connected to said air chamber, a wind guide plate positioned between said air chamber and said secondary air openings and an air inlet opening formed in an interior of the car and connected between said secondary air openings and the interior of the car and wherein said primary air openings are formed in vertically extending surfaces of angle brackets attached to the elevator car.
An apparatus for the ventilation of high speed elevator cars in which ventilation of the car interior during the travel with closed doors takes place through openings of predetermined cross-sectional area formed in the upper and lower portions of the car body and wherein a vertical air current flows in the car due to a slip stream and pressure build-up at the air-displacing car, comprising:
- an upper ventilation system located in an upper portion of an elevator car;
- and
- a lower ventilation system located in a lower portion of the elevator car, each said ventilation system permitting air to enter the car and for decelerating and relieving an entering air current when the car is travelling in an associated direction and including a trough having side walls formed in an associated end of the elevator car and a plurality of primary air openings formed in at least one of said side walls of said trough, means forming an air chamber connected to said primary air openings, means forming secondary air openings connected to said air chamber, a wind guide plate positioned between said air chamber and said secondary air openings and an air inlet opening connected between said secondary air openings and an interior of the car.
An apparatus for the ventilation of high speed elevator cars in which ventilation of the car interior during the travel with closed doors takes place through a plurality of openings of predetermined total cross-sectional area present in the upper and lower portions of the car body and wherein a vertical air current flows in the car and is produced by slip stream and pressure build-up at the air-displacing car, comprising:
- an upper ventilation system located in an upper portion of an elevator car and including an upper trough formed by a horizontally extending ceiling board attached to an upper angle bracket having a plurality of upper primary air openings formed therein, an upper outside panel and an upper support attached to said upper angle bracket and said ceiling board respectively and defining an upper air chamber connected to said upper primary air openings, an upper guide plate attached to said upper support and defining an upper U-shaped air channel connected to said upper air chamber, a plurality of upper secondary air openings formed in said upper support and connected to said upper U-shaped air channel, an outside wall of the elevator car attached to said upper support and defining an upper vertical air channel connected to said upper secondary air openings and having an upper air inlet opening connecting said upper vertical air channel with an interior of the car;
- and
- a lower ventilation system located in a lower portion of an elevator car and including a lower trough formed by a lower angle bracket having a plurality of lower primary air openings formed therein, a lower outside panel and a lower support attached to said lower angle bracket and defining a lower air chamber connected to said lower primary air openings, a lower guide plate attached to said lower support and defining a lower U-shaped air channel connected to said lower air chamber, a plurality of lower secondary air openings formed in said lower support and connected to said lower U-shaped air channel, an outside wall of the elevator car and a pedestal attached to said upper support and defining a lower vertical air channel connected to said lower secondary air openings and having a lower air inlet opening connecting said lower vertical air channel with an interior of the car.
