DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a method and system for storing and retrieving loads, for example parking motor vehicles, i.e. cars, vans. Lorries, etc, in a car park, or storing goods or other types of loads in a warehouse.
BACKGROUND OF THE INVENTION
In large cities, thousands of cars, trucks, vans and buses run on the roads beside modern and sophisticated underground mass transit systems. For the majority of drivers of motor vehicles in such large and inevitably crowded cities, car-parking has always been a problem because of the scarcity of parking space available on the one hand, and the considerable amount of expenses involved on the other. To meet ever increasing demands of motor drivers for parking space, more and more multi-storey car parks are built. Such multi-storey car parks are often erected in busy commercial areas with exorbitant land value, and their costs, in terms of construction as well as land value, are extremely high.
However, due to the fact that present multi-storey car park designs require driveways for in-coming and out-going vehicles on every level between the parking spaces, as well as spiral driveways to reach each level, much of the available floor area cannot actually be used for the very purpose for which the car park was built.
Similar problems can also occurs in large warehouses in which goods or other loads to be stored have to be transported to and from different areas within the warehouse, and traffic congestion tends to build up around the warehouse terminals.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a method of and system for storing and retrieving loads which enables optimum use to be made of the available storage space and is also capable of reducing costs of construction, maintenance and operation of the storage buildings, such as car parks or warehouses.
Accordingly, one aspect of the present invention consists in a method of storing a load in a multi-storey building and retrieving the load therefrom, the building having a plurality of storeys, situated above, on and/or the method comprising the steps of:
containerizing the load in a container adapted for storing the load,
conveying the containerized load to a vacant one of said storage spaces on one of said storeys by conveying belt and pulley means, and
subsequently conveying the containerized load by said conveying belt and pulley means from said storage space to a load collecting location for retrieval of the load from the container, and being characterized by the steps of:
lifting or lowering said containerized load, where necessary, to and from said storey having said vacant storage space by means of a lift arrangement, and once on said storey containing said vacant storage space, conveying said containerized load between said lift arrangement and said vacant storage spade by means of said conveying belt and pulley means including a conveyor located on said storey at floor level adjacent or between said storage spaces, and a pulley mechanism installed on said storey above said conveyor for transferring said containerized load between said conveyor and said storage space.
Another aspect of the present invention consists in a system for storing a load in a multi-storey building and retrieving the load therefrom, the building having a plurality of storeys, situated above, on and/or below ground level, with a plurality of storage spaces located thereon, the system comprising a plurality of containers each adapted for storing a load, and conveying belt and pulley means for conveying the containerized load to a vacant one of said storage spaces and subsequently conveying the containerized load from said storage space to a load collecting location for retrieval of the load from the container, characterized in that the system also includes a lift arrangement for lifting or lowering the containerized load, where necessary, to and from the storey having said vacant storage space, and said conveying belt and pulley means comprise, on each of
