Abstract

PURPOSE:To provide an elevator which is suitable for a building having floor wherein three sides or more of the periphery of an elevation passage can be utilized as an elevator hall. CONSTITUTION:An elevation passage 1 is divided into two sections by means of a line for intercoupling corner parts positioned facing each other and cars 2a and 2b are formed in a shape in plane which is formed in a shape corresponding to the shape in cross section of each of two division elevation passages. In entrance doors 4a1, 4a2, 4b1, and 4b2 of the cars 2a and 2b, respectively, at least two sets of the entrance doors are formed with respective corners therebetween.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator suitable for a building in which at least one of the halls on all floors can use three or more surfaces around the hoistway as a hall.

[0002]

2. Description of the Related Art As a conventional elevator, it is general that the hoistway has a rectangular plan shape and an entrance door is arranged in front of the hall.

In addition, in elevators for automobiles, there are also known elevators having entrance and exit doors on the front and the back.

[0004]

However, the conventional elevators can use three or more surfaces around the hoistway, or can change the direction of the landing for each floor or every several floors, or floors. The building was not designed to deal with a building in which the orientation of the landing was consciously changed by the floor.

An object of the present invention is to provide an elevator suitable for a building having a floor where three or more surfaces around the hoistway can be used as a platform.

[0006]

The above object is to provide a hoistway having a rectangular planar shape formed over a plurality of floors, a guide rail erected in the hoistway, and a guide rail guided by the guide rail. In an elevator equipped with an elevator car and an entrance door for entering and leaving the car,
The hoistway is divided into two along a line connecting opposite corners, and the plane shape of the car corresponds to each of the divided hoistway cross sections, and at least one of the car This is achieved by having two pairs of doors with corners in between.

[0007]

With the above configuration, when the landing direction is different for each floor, the door to be opened may be selected for each floor.
In addition, when there are three or more sides around the hoistway as a landing, you can open both doors and use one for the exit and the other for the entrance. It is possible to provide an elevator suitable for a building in which each floor is different, or a landing can be secured on three or more sides around the hoistway.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 is a plan view of a floor with a hoistway, in which a rectangular hoistway 1 (including a square) is divided into two along a straight line (diagonal line) connecting two opposite corners. And a cage of approximately triangular shape within the divided area 2
a and 2b are arranged.

At the two opposite corners in the hoistway 1, there are two
The counterweights 3a and 3b are arranged. Car basket 2
a and 2b each have two sets of doors 4a₁Four
a₂4b ₁4b₂Is provided. Incidentally, the basket 2
Guide the up and down of a, 2b and counterweights 3a, 3b
The guide rails and hoisting machines are omitted.

With the above structure, when the direction and area of the landing with respect to the hoistway are different for each floor, either _{one of} the doorways 4a ₁ and 4a ₂ facing the landing of the stopped floor, or , One of the entrance doors 4a ₁ and 4a ₂ is opened, and when the landing on that floor is facing two adjacent surfaces of the hoistway 1, both entrance doors 4a ₁ and 4a ₂ are limited to this floor. Alternatively, it is possible to open 4b ₁ and 4b ₂ and use one of the entrance / exit doors 4a ₁ and 4b ₁ exclusively for the exit, and the other entrance / exit doors 4a ₂ and 4b ₂ only for the entrance.

Further, even if the floor has a hall facing both the entrance doors 4a ₁ , 4a ₂ or 4b ₁ , 4b ₂ , it is dedicated to the exit when there are no passengers (no hall call). If only the doors 4a ₁ and 4b ₁ are opened, the floor concerned is not registered as a destination floor (no car call), and the floor is reached only by a landing call, the entrance door 4a dedicated to the entrance _2, 4b ₂ can only be controlled to open, it is suitable for buildings with a landing different orientations for each floor.

[0013]

As described above, according to the present invention, when the landing direction is different for each floor, the door to be opened may be selected for each floor, and three or more surfaces around the hoistway may be selected. In the case of a landing, you can open both doors and use one for the exit only and the other for the entrance. It is possible to provide an elevator suitable for a building that can be secured on three or more sides around the hoistway.

Claims (1)

[Claims] 1. A hoistway having a rectangular planar shape formed over a plurality of floors, a guide rail standing upright in the hoistway, and a car and a car which is guided up and down by the guide rail. In an elevator equipped with an entrance door for entering and exiting a car, the hoistway corresponds to each hoistway cross section divided into two along a line connecting opposite corners and the plane shape of the car is halved. The elevator is characterized in that it is formed into two shapes, and that at least one of the entrance doors of the car is equipped with two pairs of corners.
