Description

Corner elevator and car thereof

Technical Field

The utility model belongs to the field of hoisting equipment, and particularly relates to a small household elevator car and a corner elevator using the same.

Background

At present, along with the popularization of home elevators, more and more rural houses can select the home elevators which are arranged indoors and are lifted in two to five layers of spaces. The current mainstream home elevator is represented by the prevailing brand, and the elevator model is found in the prevailing prior patent CN 107265252A-an elevator system. Such elevators nevertheless achieve concealment of the hoisting system. However, the elevator runs on a flat wall, and more households tend to place the elevator at the position of an indoor corner for the purpose of saving space, so that the conventional household elevator has the problem of insufficient space utilization.

Another prior patent US8141686B 2-corner lift device (corner lift device) discloses a corner lift adapted to an indoor corner, which effectively utilizes the space of the indoor corner, but the lift car of the corner lift is in a regular triangle shape, and we think that the structure of the lift car has a problem of insufficient space utilization. The main reason is that sufficient space is generally reserved at the position of a car door, so that people can get on and off the elevator conveniently, and the reserved space is limited by the corner position and generally tends to be square, so that the plane door of the triangular car has the problem of space waste.
