BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an elevator system for multi-

The present invention relates to an elevator apparatus for vertically and horizontally conveying a multi-section of an upper composite type.

In general, an elevator is a device for transporting people or objects up and down at different heights, mainly installed in a building and used for vertical transport of people or cargo between floors and floors.

Meanwhile, an elevating system capable of horizontal transfer instead of vertical transfer has been proposed. For example, Japanese Unexamined Patent Application Publication No. 1998-042456 (published on Aug. 17, 1998), Registered Patent Publication No. 10-1010362 (Japanese Patent Application Laid-Open No. 10-1200988 (Published on November 16, 2012) and Published Japanese Patent Application No. 10-2014-0021674 (Publication Date: 2014.02.20) disclose that vertical and horizontal transport of passengers or cargo It shows possible transportation system.

These vertical and horizontal transport systems can be installed and operated in a building as well as in various forms.

In general, an elevator system that vertically ascends and descends as a transit structure for ordinary passengers, the disabled and the elderly in a section where passengers transit to other transportation means such as overpasses installed on the road, transit passages for subways or trains, I have installed.

The elevator system is capable of vertical transfer only and horizontal transfer is not possible so that the handicapped person or the elderly person must ride on the elevator and then move back to the next place by walking.

The conventional vertical elevating type elevator, inclined type elevating type elevator, or horizontal moving type elevator can help a person with a disability and a elderly person to move to a certain distance. However, in order to use a plurality of elevators or horizontal moving devices installed in a subway or a transit section of a train It is congested with the movement line of the general public, and it does not really help the handicapped or the elderly.

Especially, a disabled person who is inevitably moved by a wheelchair is moved together with a general passenger, resulting in a lot of inconvenience to both the passengers and the disabled, and the congestion is further increased.

Therefore, there is a desperate need for a vertically and horizontally conveying type elevating device which allows a general user, a handicapped person and an elderly person to move at a time in a plurality of sections including a horizontal section and a vertical section.
