Abstract
An elevator having a power feeding apparatus effective for reducing the installation space for the elevator is disclosed. The dimension of the power transmission part disposed at the hoist way and the dimension of the power receiving part mounted on the counter weight, each measured in the direction along which the counter weight moves are made different from each other.
Claims15
An elevator having a car and a counter weight, each suspended by a rope, comprising
- a power transmission part located in a hoist way in which said car and said counter weight moves;
- and
- a power receiving part installed in said counter weight and receiving an electric power from said power transmission part, wherein
- a dimension of said power transmission part and a dimension of said power receiving part, each measured in a direction along which said counter weight moves, are different from each other and wherein
- said dimension of said power receiving part is larger than said dimension of said power transmission part.
An elevator having a car and a counter weight, comprising
- a first power generation apparatus and a second power generation apparatus located in a hoist way in which said car and said counter weight moves and for generating an electric power to said car or said counter weight, wherein
- a projection of said first power generation apparatus and a projection of said second power generation apparatus, each projected in the direction along which said car or said counter weight moves, have an overlapped area.
An elevator having a car and a counter weight, comprising
- a first power transmission part and a second power transmission part located in a hoist way in which said car and said counter weight moves and for generating an electric power to said car or said counter weight, wherein
- a projection of said first power transmission part and a projection of said second power transmission part, each projected in the direction along which said car or said counter weight moves, have an overlapped area.
An elevator having
- a first car and a first counter weight, each moving in a first hoist way, and a second car and a second counter weight, each moving in a second hoist way;
- comprising
- a first power transmission part for transmitting an electric power to said first car or said first counter weight;
- a second power transmission part for transmitting an electric power to said second car or said second counter weight;
- and
- a power generation apparatus connected commonly to said first and second power transmission parts and for generating an electric power to be transmitted from said first and second transmission parts.
