[0001] This patent application for an industrial invention concerns an automatic system
for the orderly parking of motor vehicles.
[0002] The invention was designed with the intention of providing a considerable contribution
towards solving the problem of creating car-parks in town centres, where, given the
ever increasing number of motor vehicles in circulation, it is becoming more and more
difficult, if not actually impossible, to find an available space to temporarily park
a vehicle.
[0003] In fact, it can be observed that the structures currently in existence are not at
all satisfactory; parking spaces at street level prove to be absolutely inadequate,
while underground or multi-storey car parks, when they actually exist, oblige the
driver of the vehicle to perform rather lengthy operations in order to park his vehicle,
which involve taking the necessary ticket, and then returning subsequently in order
to pay for parking and actually collecting his vehicle.
[0004] Moreover, these car parks in most cases, are rather chaotically organised, in that
while on one hand, it is necessary to employ a considerable number of garage attendants,
who are able to park the cars and if necessary move them to make room for others or
to enable other cars to be collected; on the other hand, the safety of the parked
vehicles is at risk, in that quite often, in the course of the many parking manoeuvers,
the bodywork is damaged when the vehicles accidentally come into contact with each
other.
[0005] The basic idea of the system according to the invention is to offer the possibility
of parking a large number of vehicles, even in areas where there is the greatest demand,
by using a particularly rapid parking technique which requires no manual intervention
and entails no risk to the safety of the motor vehicles.
[0006] This system comprises a circular structure on several levels, each of these levels
having an annular track on which concentric rings are mounted, which are able to rotate
in an autonomous manner, by means of a suitable drive mechanism.
[0007] On each of these rotating rings, there are spaces above each of which it is possible
to park a vehicle, in such a way that when the system is full of cars, on each of
its levels there are as many concentric rows of parked cars as there are rotating
rings.
[0008] To lift or lower each individual vehicle from the various levels, there are one or
more lift trucks, able to ascend or descend along vertical pillars.
[0009] It is clear that by combining the vertical action of these lift trucks and the rotating
action of the concentric rings on the various levels, it is possible to position each
individual vehicle fully automatically and in a particularly precise manner.
[0010] It should also be noted that the concentric rings can be different widths, so as
to make the best possible use of the space available or so as to be able to adapt
the spaces to suit the various types of vehicle according to their dimensions.
[0011] Moreover, it should be emphasised that in order to provide the vehicles with easy
access to all the various concentric rings on each floor, the rings nearest to the
lift truck pillar, have a track not to be used for parking, along which the vehicle
can travel in order to reach the selected parking space.
[0012] At this point, in order to describe in practice, the automatic parking operation
by means of the system at reference, it can be said that the driver merely has to
position his vehicle in the vicinity of the lift truck, after which the electronic
brain of the system, having singled out a suitable parking space for the vehicle,
then sets the lift truck in motion, on which in the meantime, the vehicle has been
positioned, and simultaneously sets the concentric rings in rotation on the level
on which the car will actually be parked, in such a way that when the lift truck reaches
the established level, the car will be lifted from it and guided in a single rectilinear
movement, drawn by an automatic mechanism, to the empty space which has been selected
for it and which in the meantime, has already been prepared exactly in front of the
lift truck itself.
[0013] This parking system is extremely practical in that when the lift truck ascends vertically,
the concentric rings rotate simultaneously, so that the vehicle can be immediately
positioned in the space assigned to it, as soon as it reaches the level selected,
without the waste of time encountered for example, in automatic storage systems, in
which the articles to be arranged, must first of all be lifted vertically and are
then moved horizontally until they reach their assigned space, after these two different
actions have been effected one after the other.
[0014] In fact, it can also be said that in traditional storage systems, the article to
be arranged finds its own space under suitable guidance, while on the other hand,
in the system at reference, once the vehicle reaches the level selected, the space
assigned to it on each separate occasion, actually appears directly in front of the
vehicle.
[0015] In other words, the system at reference makes the orderly parking of motor vehicles
extremely simple but above all, greatly reduces the time necessary for this operation.
Consequently, due to the structural layout of the system, it is possible to park a
considerably larger number of vehicles than in other modern more or less automated
car parks in the same space of time
[0016] It is clear that the collection of the vehicle by the owner is also carried out in
the same short space of time and with the same security by exactly reversing the procedure
just described.
[0017] When compared to current car parks, the system according to the invention is also
preferable because of the particular shape of its construction; in fact, its circular
structure on the one hand, guarantees optimum use of the spaces available and on
the other, lends itself most efficiently to controlling earth thrust in underground
construction, in consideration of the fact that it is of no conseqence if the system
at reference is actually adopted on steel or reinforced concrete structures, in totally
underground, multi-storey or mixed constructions.
[0018] In a preferred embodiment, the task of lifting the cars has been assigned to two
lift-trucks, which autonomously slide vertically on opposite sides along a pillar,
positioned precisely in the centre of the structure, namely the space circumscribed
by the various rings one above the other; it should be noted however, that within
the scope of the same inventive idea, there is nothing to prevent said pillar on its
own or with other similar pillars, from being positioned in the area surrounding
the outermost ring on each level; in this case, the car loading operation on the various
levels would not take place from the outside towards the inside, but vice-versa.
[0019] Moreover, it is possible for the central pillar to support four different lift trucks,
which slide vertically along four sets of rails applied to the pillar itself at regular
90° intervals of space; in this case, the pillar itself could be provided with the
possibility of rotating around its longitudinal vertical axis, thus being able to
maintain the same position for the entry and exit of the vehicles. In the same way,
this possibility of rotating could also be applied on the pillar which supports only
two lift trucks; if this were the case, this solution would allow the direction in
which the cars enter and exit to be orientated in the best possible manner.
[0020] The constructive solution of the system with several lift trucks on the same pillar
or several pillars on its structure, would be particularly efficient at peak times,
when it would be necessary to satisfy in the shortest possible time, the requirements
of a large number of consumers at the same time, whether they be looking for a parking
space or wishing to collect their vehicles from a parking space. In conclusion, it
should be said that although the system is always automatically controlled by an
electronic processing centre which attends to all the necessary operations and therefore
makes it unnecessary to employ labour, apart from when simple periodical checks and
normal maintenance must be effected, it is also possible, if required , for the system
to be operated manually.
[0021] For further clarity of explanation, the description of the invention continues with
reference to the attached drawing, reproduced for illustrative and not limitative
purposes, in which :
- Fig.1 is the plan view of the system at reference in the version with central pillar
for lift trucks;
- Fig.2 is the section with the II-II plane from Fig.1;
[0022] With reference to these attached drawings, the system is composed of a series of
annular tracks one above the other (1), above which, several flat concentric rings
(2) can rotate and on which the vehicles are actually parked.
[0023] In the space at the centre of this structure, there is a vertical pillar (3), along
which lift trucks (4), provided to lift the cars to be parked to the various levels
of the system, can slide from the bottom towards the top and vice-versa.
[0024] With reference to Fig.1, the number (5) indicates the spaces which the innermost
concentric rings on each floor must keep free, to allow the vehicles drawn by the
lift truck to reach their destination on the outermost rings.
[0025] It is clear that if the vehicle has to reach the outermost ring, the sections through
which it must pass on all the other innermore rings must be aligned (illustrated in
Fig.1) to form a single passageway which leads directly to the space to be occupied
by the parked vehicle.
[0026] The electrical, electronic and mechanical devices connected with the structure according
to the invention have been expressly omitted from this description, in that they should
be considered of normal design and therfore well within the capacity of any experienced
engineer.
