Abstract: Hall call apparatus for a low-cost, low rise simplex elevator, all disposed on the hoistway doors, include a slider 25 which is released by depression of a hall call button 21 so that it is pulled upwardly by a spring 49 until it engages a stop 50. A clapper 33 overtravels when the slider stops and contacts a bell 34 to provide an audible indication that a call is registered. Holes 23, 24 in the hoistway doors form a chevron-like pattern through which colored chevron-like stripes 28 on the slider will show, to provide a visual, directional indication of the registration of the call. A passive transmitter disposed on the slider passes through flux of a permanent magnet 30 to cause a unique RF signal transmission from an antenna 31 that is picked up by an antenna 71 on the elevator car to indicate the floor and direction of the requested hall call, which may simply be applied to the car operating panel to force a car call in order to answer the request for service at a given floor.

Abstract: A direction indicating device (4) for elevators is built into the door frame (3) near a floor door (1). The device (4) consists essentially of a retaining element (9), an up-direction arrow (10) and a down-direction arrow (11). In order to make the indicating device direction arrows (10, 11) visible from possibly all positions or viewing angles of the passengers on the floor, the device (4) is arranged on the door frame (3) three dimensionally with the direction arrows (10, 11) mounted on the front wall (14) as well as on the side wall (15) of the door frame (3). For further improvement of the visibility, another indicating device (4) can be arranged in a similar manner on the other side of the door frame (3). With the arrangement of this indicating device (4) on both sides of the floor door (1), a practically total visibility of the direction arrows (10, 11), through almost 180 degrees in the hallway, is assured.

Abstract: In a display (202) comprised in an elevator system, more than one floor symbol (205) but less than all the floor symbols corresponding to different floors in the elevator system are highlighted at a time. At least the floor symbol corresponding to the current position and that corresponding to the next floor in the travelling direction is highlighted. The display is preferably so controlled that it scrolls the floor symbols (205) with respect to the car symbol (203). When the elevator car is at a given floor, the floor symbol corresponding to such floor coincides with the car symbol, and when the elevator car moves away from the floor, the floor symbol ceases to coincide with that car symbol, and as the car comes to the next floor, the corresponding floor symbol coincides with that car symbol.

Abstract: A display apparatus within elevator cabs or elevator waiting areas that facilitates the simultaneous display of advertising and general news information is described.
