χ 116377 LIFT SYSTEM

The invention relates to an elevator system according to the preamble of claim 1.

Generally speaking, solutions to increase the transport capacity of elevators in tall buildings and to reduce waiting times have long been developed. According to the conventional method, the elevator system has as many as 10 shaft lifts. By carrying out the movement of elevator cars without elevator ropes, it is possible to transport many trucks simultaneously in the same shaft, thereby increasing the transport capacity. The cost of constructing and maintaining elevator shafts is high and it is necessary to develop solutions to reduce them without limiting transport capacity.

Several gap structures have been developed for the above problems. For example, US 5501295 discloses that several elevator baskets can travel to the same shaft simultaneously without 20 elevator ropes, and in addition, the baskets can travel from one shaft to another. According to the publication, the baskets are moved by rollers both vertically and horizontally along the lanes reserved for them, utilizing a particular type of motor technology. DE

The object of the invention is to provide a novel economic elevator system capable of increasing transport capacity.

With regard to the aspects of the invention, reference is made to the characterizing part of claim 1. For other preferred embodiments of the invention, reference is made to the dependent claims.

According to a preferred embodiment of the invention, the traffic in the building is enhanced by reducing the number of shafts relative to the number of elevator cars and by placing the required number of horizontally projecting spaces on the required floors, such as both the ground floor and busy floors. In the elevator system of the invention, there is at least one protruding space. In the system, the number of elevator baskets is at least one more than the number of elevator shafts. Advantageously, the protruding spaces may be for one or more elevator cars, whereby they may serve as a stopping place, whereby the car which has been stopped there can be bypassed by the cars passing in the shaft. The baskets can thus exit the passage of the baskets passing them in the shaft. If many baskets are stopped in the protruding space t, it is possible for the car which has first moved into the protruding space j * to move further into the protruding space in order to avoid other collisions entering it simultaneously. According to the invention, it is possible to move multiple cabs ···, simultaneously in one shaft without congestion of traffic.

* · T · !! Baskets move independently between shafts without being blocked by each other. On the basis of the estimated traffic volumes of the buildings, the required number of vertically extending spaces is placed in vertical shafts.

According to a preferred embodiment of the invention, the shafts target. In addition to the exterior doors, level doors can be placed in the protruding compartments, so that there is a possibility of • passenger transport between the baskets and floors in the exterior compartment. According to the invention, more level doors than shafts can be provided on at least one floor, thus preferably 116377 avoiding congestion on floors with a large number of passengers. This can be, for example, the restaurant floor or the ground floor from which passengers enter the building.

The elevators of the system according to the invention can be arranged in different elevator groups which can be controlled using the computer-controlled group control only in the floor zones intended for them. According to the invention, the movement of the bodies both horizontally and vertically can be accomplished using the linear motor technique, wherein the stator of the motor is arranged on the shaft wall and the movable part of the motor is connected to the body. Advantageously, by utilizing the engine technology in question, it is possible to both move and support the elevator car using the same equipment, and no ropes are needed to lift the cars. The baskets pass through the gaps both up and down the floors without being blocked by each other. According to one embodiment of the invention, maintenance of the elevator can be arranged in the projecting space.

The novel elevator system according to the invention brings several advantages to the elevator arrangement technology in the building. By reducing the number of vertical shafts, they save on construction and maintenance costs and leave some of the shafts more space for other uses in the building.

: 25 By positioning the protrusions that extend horizontally into the shafts as a stopping place for the space and the baskets, the moving baskets are bypassed, ···. Baskets move in shafts both horizontally and vertically !! direction by linear motor technology without the ropes themselves seemingly without being an obstacle to each other. The baskets are also movable between vertical shafts. Preferably
