ABSTRACT OF TH~ INVBNTION
This invention refers to a multiple parking system of a radial and mechanized type, which is highly efficient since it requires very little space for circulation, as ~ ;
compared with the area used specifically to park the cars. ~ ;-This allows for a better use of urban space, efficient operation and a reduced investment cost. --~AC~GRO~ND OP TEE INVENTION
Field of the Invention This invention refers to a mechanized, radial type parking system, allowing twelve vehicles to be parked per floor without the need of areas for maneouvring or circulation, and which applies to any urban area, especially where the land is scarce and expensive. The result is a high level of efficiency and density for vehicle parking as compared with the overall land and building area. A parking lot of this type is described in the applications for Mexican patents Nos. 927515 and 936173, belonging to the same titleholder of the present -;
patent application. ~
Prior Art Previously-existing parking ~y~tems are very varied, and can be classified in non-mechanized and mechanized categories. The first provide ease of circulation to allow vehicles to move from the entrance to the parking space, whether located on a single ground-level floor, or on a higher floor where access is by means of a sloping ramp, or where the parking spaces form part of such ramp. These parking lots are characterized by low efficiency, high investment costs, the need for a large land and construction area, and low operating and maintenance costs. The ~econd type of parking lots (mechanized) are characterized by a higher level of efficiency, ranging from those with a low level of sophistication which combine an elevator mechanism with circulation lanes, to fully mechanized systems where the vehicles are suspended in the lifting equipment itself or in vertically-placed ~ -niches. Use of the latter has been extremely restricted and for very specific applications, due to their high investment cost. -~
The foregoing demonstrates the need for designing and building parking systems which combine the following factors of primary importance~
a) An efficient use of urban land 3 21~2~3 :~ ~
b) Vertical construction, to allow greater parking capacity c) The requirement for land or reduced dimensions d) A low investment cost e) A low operting cost f) High efficiency in connection with the area needed for parking a car vs. the overall construction area g) Reliability h) Low maintenance i) Low live weight v9. dead weight ratio of the ~ ~
parking sys~em ~ 9 j) Easy operation k) Modular construction 1) A capacity which can be expanded m) Recovery of investment plu9 operating costs A radial mechanized parking system takes the foregoing design factors into consideration, providing potential ~;
benefit~ in technical and economic aspects.
~ ~ .
OBJECTS OP T~E INVeNTION
The object of the present invention is, therefore, to provide parking for cars in a mechanized, radial-type system which is efficient, novel, functional and extremely economical for installation in urban areas.
4 2l~2~l~3 ~:
The other object of the present invention is to optimize the use of urban land areas by parking vehicles on two or more floors.
Another object of the present invention is to eliminate car circulation, ascent and descent ramps and lanes, in order to better utilize the available construction area of the parking system.
An additional object of the present invention is to have a car-lifting system which, once vehicles are lifted from one level to another, revolves on its own access to allow them to be placed at a suitable angle for ascent and descent.
Another object of this invention is to provide parking where the dead weight of the building is relatively low when compared with the live weight of the cars ad their occupants, in order to reduce the investment cost~.
Yet another object of this invention is to provide a mechanized and semi-mechanized system to work faster in placing the cars, and which operates with a high degree of security for the occupants, the operating personnel, the vehlcles and the parking system itself. ;~-Finally, a object of the present invention i9 to provide a modular parking system the capacity of which can be increased in accordance with the needs of each specific case, and which is easily made, put together and operated.
-~
2112'~ 3 ', The foregoing objects become reality with a new parking system of the radial, mechanized type, consisting basically of a foundation slab of reinforced concrete which will serve as a supporting platform for the structure of the building, as well as, serving as the lower floor of the parking system; a metallic or concrete structure with radial girders sustained by suitably~
distributed columns for supporting both the dead weight of the building and the live weight of the cars and their occupants; a revolving elevator of a hydraulic or hydraulic with cables type in the center of each tower which, in addition to hoisting the vehicles, revolves around a central axis to acquire any of twelve preselected positions within 360, a signalling and control system which allows the operator to identify unoccupied spaces and make the elevator cabin stop vertically on the desired floor and horizontally in the required position, while at the same time allowing safe operation of the elevator in order to prevent any movement or rotation while a vehicle i8 being lifted or lowered to the elevator cabin.
More specifically, the parking system of the present invention consist of a cylindrically-shaped building of two or more floors in the form of a circular crown, placed one obove the other in perfect alignment, in such a way that its structural elements coincide when seen from above. The floors are supported by columns in such a way 21~ 2163 that each floor has the capacity to hou~e twelve radially-placed cars.
A car elevator is placed in the center of the circular crown of each floor, which will raise or lower these to each floor or from each floor to ground level, and will position them by revolving on its central axi~ in the ascent or descent angle of the elevator required, according to the relative position of the parking space or point of exit. A feature of this elevator is that, in addition to its transfer movement, it also rotates the structural guide tower, the carlift and hydraulic lifting system. The elevator consists of a vertical revolving structure which turns- on its vertical longitudinal axis and which, in its lower part, serves as a support for the hydraulic lifting equipment and as a guide for the lifting cabin which runs vertically within the guide bars of structure itself. The metallic structure consists basically of a revolving table in the form of an inverted pyramid which supports two structural legs throughout the vertical length of the entire elevator and the hydraulic equipment, and whose upper extremity is another pyramid.
Two central axis (an upper and a lower placed on the vertexes of the pyramids) formed by ball bearings, make up the revolving axis of the structure, the cabin and the hydraulic equipment by the action of an operator on the lower part of the table who, through a crown gear, a 2 ~ ~ 2 ~
pinion and an electrical gearmotors, starts the rotatory movement which will permit the radial positioning of the elevator cabin in each of the twelve parking places corresponding to each of the floors.
: -:
The elevator will be actived by an oleohydraulic system ~ ~-.
equipped with hydraulic pistons and pumps RO that, when the pistons move outside the cylinders, the elevator cabin is raised, and vice versa. The elevator is also equipped with electrical and electronic controls to allow its ascent and descent operation, turn clockwise and counterclockwise, and controls to prevent its transfer and rotating movements if the vehices obstruct the light ray of the photocell installed at the entrance to the rotating platform of the elevator itself.
The parking system will be equipped with a complete indication and control system, by means of which the equipment moves semiautomatically to allow the admission of cars, indication of vacant spaces, access, raising and rotation of the elevator, and the elevator call. The . .. ...... ...
indication and control system consists basically of a logical control programmer, a control panel which governs the elevator, call buttons, obstruction sensors, ;~
positioning sensors and proximity sensors. The system as a whole will have a specially-designed operating language and logical programs for exercising the desired actions in -~. ~. . ; .
2~2~
accordance with the specific configuration of the equipment.
Finally, the parking lot will be equipped with stairs and an elevator for transporting clients in order for users to be transported to or from each floor of the building.
The characteristic aspects of the present invention will become clearer and easier to understand as the features of the new parking system are de~cribed, making use of the attached drawings for this object.

In order to explain better and clearly the new parking system, the following description has been divided into chapters, each of which referred to a fundamental part of the parking system.
PAR~ING ~UI~DING
The parking building consist~ of a vertical structure, of either reinforced concrete or, preferably metallic, which is usually cylindrical in form with several floors, which can be from two to an indefinite number, in accordance with the special conditions of each case.
The building structure can be supported by foundations, depending on the specific conditions of the project, the height of the building, the overall weight, the 90il conditions, etc. These foundations can take the form of an extended slab of reinforced concrete (1), isolated shoes or continuous foundations in the form of concentric circular rings.
Columns ~2) are placed on the foundation slab to support ! ` I the first floor and the primary girder3 (3~, which are placed in radial form, the interior end of each radial girder (3) in cantilever, since there is no center column as this would hinder the transit of the cars. All the radial girders on each floor(3) shown in figure 3, finish and are joined in a circular ring or a structural dodecagon (4), which limits the central space where the ~' ' 14 2 ~
car elevator (10) circulates. Secondary and terciary girders (5,6) are connected to the primary girders in transversal form in order to provide sufficient rigidity and support for the floor (7) of each parking level.
The floor on each level can be made of reinforced concrete slabs or, preferably, steel sheeting (7) of a caliber suitable for the live weight it must support, being in the form of a natural U and an inverted U fo form a continuous accordeon, thus achieving a substantial reduction in the weight of each level, with a reduced dead weight and a lower investment cost.
The building will have stairs (~) and an elevator (9) for parking users, to be placed as shown in figures 1, 2, 3 and 4.
~Q~IPM D T
The equipment will consist basically of two items, each covering various components of the system. The first item is the car elevator (10), in its various embodiments, and the signalling and control system (figure 11).
MFC~ANICAL ~Q~IP~WT FOR LIFTING AND POSITIONING CARS
The car elevator (10), as its name indicates, i9 intended to lift or lower vehicles to each of the operating levels and place them in an exact entry or exit position, complementing the effects of the transfer and rotation required for car placement, and reducing manouevres to a minimum. The car elevator consists of a supporting, ' ~ ~'"' 2~1`2 L~
rotating and guiding structure (11), as shown in figures 5, 13, 15, 17, 20, 23, 25, 29, 32 and 36 related to each ~
embodiment of the elevator, which is formed by two ::
structured metallic columns (11) joined only at top and ~ .
bottom which are vertically parallel and serve as a guide for the elevator cabin (25). The lower part of the :--~
structure (11) ends in a kind of inverted pyramid (12) (partially shown), where the lower corner acts as a .. . .
rotating support for the entire tower, including the elevator cabin and hydraulic equipment, utilizing an axial type bearing (15) which i9 firmly attached to the foundations on one side, and to the lower inverted pyramid of the structure also -ends in a kind of structural pyramid with a transversal element which joins the two legs of the structure (11) guiding the elevator, the pyramid having another bearing, in this case for axial type loads, in the center o vertex (21), the lower part of which is joined to the elevator tower (11), while its upper part is connected to four horizontal girders (22) forming a cross- shaped ! member.i Girders (22) are, in turn, attached to four internal columns (2) of the parking building (figure 4), ~in order to keep the vertical rotating shaft of the elevator itself centered and properly aligned. The two structural metallic columns are composed of primary elements (11), which form a vertebral column in conjunction with secondary elements (13), which will ~' ', ' '' 16 21~ 2~3 increase their rigidity by providing better proportions, above all in parking system where it is necessary to install a greater number of floors. The primary vertically- placed structural elements (11), serve as support for installing the vertical parallel rails (17), which will guide the ascent or descent of the elevator cabin (25). The secondary elements (13), aside from providing additional rigidity to the primary elements, allow the secondary guiding rails (14) to be stiffened for the upper pulleys (20) of the pistons (36) of the elevator's hydraulic system, avoiding in this way any possible misalignment in the vertical piston stroke on leaving or entering the cylinders (35).
The lower part of the elevator structure is also intended to house the elevator hydraulic system (19), consisting of the oleohydraulic tank, the hydraulic pressure pumps, the control valves and the cylinders (35), together with their hydraulic pistons t36) and, on the other hand, houses two electrical gearmotors (24), which are vertically placed and which at their ends, protruding from the rotor shaft, are connected by two pinion-type gears which turn around a circular crown (23) of straight gears which are firmly attached to the concrete foundation (1) of the elevator itself. The drive of the two geramotors will result in the entire elevator (10) as a whole (metallic structure, cabin, hydraulic system, etc.) turning around the vertical shaft driven by the movement of the electric gearmotors (24) around the crown of gears (23). The motive elements consist of electric motors which receive a precise signals from the control system in order to adopt a position preselected by the master control of the logical control programmer, clockwise or counterclockwise, permitting a turn in the shortest direction between the original cabin po~ition and final destination position.
The oleohydraulic equipment of the elevator consists basically of the following essential elements: One or two metallic tanks (19) for storing and returning the system~s hydraulic oil; one or two hydraulic pumps activated Dy electric motors (not shown in the drawings), which are placed inside the oleohydraulic tanks with a submerged type installation, and are moved by one or two electric motors (not shown) which, on functioning, inject the hydraulic oil through the control valves (not shown) towards the lower part of the hydraulic cylinder (35) placed on each side of the cabin ~25), and running parallel to the metallic structure (ll) and the guide rail (17). Two pulleys (20) are placed on the upper ends of the cylinder pistons (36), said pulleys supporting the elevator cables (34), and being fastened at one end to the structural base of the revolving tower (12) and, at the other end, are connected to the elevator cabin (25). The electric actuation of the hydraulic pump motors results in ~ 18 2~2~3 the oil from the storage tanks being injected at high pressure at the base of the hydraulic cylinders (35), which results in the pi~tons (~6) being vertically displaced upwards and outwards, 90 that the metallic cables (34) fastened to the elevator cabin are displaced in one direction to that the cabin itself rises with a run equal to twice the stroke of the hydraulic pistons. When the electric motors of the pumps turn anticlockwise, they will ab~orb oil from the hydraulic cylinders and transfer this to the storage tanks, retracting the pistons and displacing the metallic cables anticlockwise, 90 that the elevator cabin descends.
The elevator cabin (-25) consists of a box of metallic sheeting in parallelepiped form, suitably reinforced by structural elements (26) to allow it to be hoisted from the transversal ends, preventing their permanent deformation. Some guides (27) are placed on the upper and lower edges of the cabin, which can be the sliding shoe or revolving bearing type which engage the guide rails (17) on three sides, allowing the cabin to move vertically, perfectly guided, thus achieving the de~ired alignment of the cabin (25) throughout its vertical journey. Two metallic guides (28) are placed inside the cabin for car tires, 80 that these enter or leave the elevator in the direction and with the alignment required for their suitable functioning. At one end of the elevator guides .~ .
~F~ ~
2~2~3 ; ~ ::19 . ' .
(28), automatic traps (29) are placed for the front wheels of the vehicles, in such a way that when they are actived the movement of the wheels i9 hampered either accidentally or on purpose. The traps (29) consist, for example, of four structural steel plates or angles placed in reverse, which slide or turn by means of a gear and lever mechanism, which is moved by a mechanical actuator (30), with an electrical or reversible hydraulic motor, 90 that the angle wedges or plates in front of and behind the `~
front wheel~ of cars to prevent their moving when the traps are applied, or are withdrawn by either sliding or turning a center at one end to withdrawn from the path of the vehicles and free the tires, allowing them to move over the guides (28) of the elevator cabin. Bipartite metallic doors (31) will be placed at both ends of the elevator cabin, which slide towards each side of the -~
cabin. The doors are electrically operated by a mechanism which is actived once the elevator cabin has been vertically and angularly placed in front of each of ;~
parking spaces. `
Protective barriers (32) are placed on each floor of the parking building, around the car elevator shaft, for the purpose of preventing any person or car from coming too ~ -close to the open elevator shaft. These barriers are folding and are raised upwards by pushing a stem (33), which is moved automatically by an extension mechanism of '.`: ~.,', ' -; '' :' 21~2~
the elevator itself, connected to the actuator (30) of the elevator traps.
Two spring shock absorbers (18) are placed on the upper part of the turntable (12), the purpose of which is to progressively reduce the impact of a sudden descent of the elevator cabin. ~
INSTR~MENTATION AND CONTROL EQ~IPMENT --The signalling and control system of the parking system forms a basic part of same, since this permits the semiautomatic and safe operation of the entire system. A
more advanced version of the same is the fully automatic control system, which is described as embodiment hereafter.
The gèneral configuration of the semiautomatic control system for the parking system takes various forms into consideration, based on the basic equipment, the sophistication of which can increase to the point where a fully automatic system is obtained.
The basic equipment consists of the elements shown in figure 11. The instrumentation and control system consists basically of three interconnected subsystems to provide the necessary operating and safety conditions, which are:
a) Subsystems for entering, paying and leaving the parking building. -b) Subsystem for occupying and calling the elevator.
-.;--,....
2 ~
c) Subsystem for controlling and raising the elevator cabin, together with the latter's security system.
S~9SYSTEM FOR BNTE~NG, PAYING AND ~EAVI~G TEE PARRING.
This system consists of one, two or three folding access barriers (37) and conventional ticket machines (38), which will have car presence detectors which permit these to enter when there are space3 available, or refuse entry when the signal of the Logical Control Programmer shows that there are no places available. On another aspect, this system includes the conventional collection system (39), which consists of a parking time reader which issues the cost when the time recorded is multiplied by the unit cost of the time unit. Both items of egiuipment, that for issuing tickets and that for reading and invoicing, can be replaced by acces3 and exit equipment which utilized plastic cards with magnetic ;~
tapes, achieving the same efect.
The system described here is connected to a logical control programmer and a conventional personal-type computer (40) which, in turn, forms part of the elevator operation and call sybsystem.
If the ticket issuer i9 of the bar code type, showing date, hour and minute, a car reader will be installed which will calculate the length of stay and the invo~icing.
2~ ~2~
EL~VATOR O~BRATION AND CALL SUBSYSTEM This system consists basically of a Logical Control Programmer (41) with suitable entry and exit signals, for receiving occupation ;~
signals from each parking space, the permanent location of the elevator cabin, and to give the command signal to the elevator to attend a request. The Logical Control Programmer will have doors to connect the personal computer, which will have doors occupancy conditions and the calls pending answer on the monitor screen, together with the possibility of calculating invoicing and showing the operation acrual. It will also show autodiagnoses of the status of different system elements.
The Logical Control Programmer has additionala -~-communication ports for connecting a portable programming computer, the card reader, a VHF frequency radio modem (42), the ticket issuer and the data channel or "bus"
(43), obtained from the cable concentrators (44) on each floor of the parking building.
There are two primary elements in each parking space which will transmit signals to the logical control programmer. The first are photoelectric cells (45), which will detect the presence or absence of a car in each space, showing their availability for occupancy, which will be located by means of the logical control programmer to a specific space as a possible destination of the elevator to unload cars. The second will be the call 2 1 1 2 1 ~
.,:, 23 ~ :
buttons (46) located in each parking space which, on being pu~hed, will request the presence of the elevator at the correct floor and in the correct radial position, to permit the exit of a specific car from the parking building. Both the photoelectric cells and the call -buttons will be connected to the logical control programmer by means of cable concentrators (44), which will clas3ify the signals to identify their origin and send them through a data bus to a signal converter (47) which will, in turn, be connected to the logical control programmer.
EL~VAT~R CABIN ROTATION AND RAISING CONTROL SU~SYS N AND
SAFBTY SYSTE~ T~FRBFOR .
The purpose of this invention is to command the actions of the elevator. Some of these ar~ of the conventional type, such as the opening and closing of doors, the detection of door obstructions, the raising and descent of the elevator :-cabin, the closing of the hydraulic valves, the sequential registration of calls requesting the elevator and the floor destination to which the elevator should be sent.
Others are completely innovative, such as th transmission ~: .
by VHF bandradio (42) of requests from the different users located in parking space, the rotation of the elevator around its vertical shaft to place itself in a required radial position, application of the counterturn brake to avoid horizontal rotation,the permanent location of the 2~2~63 cabin tran~mitted to the logical control programmer and application of the elevator cabin tire traps, among others.
The control equipment consists of the conventional equipment used for elevators, which is not described since it is in common use, to which controls similar to that of : :
vertical elevation will be added to achieve the startup, ;--acceleration, deacceleration, stoppage and braking of the angular rotation motors of the elevator cabin by means of the speed reducers (24), which act on the gear crown (23).
In order to transmit the orders coming from the parking system, photoelectric cells (45) and call buttons (46), a cordless data transmission will be utilized, using a pair of "duplex" type transmitters/receivers on the VHF (Very ~- .
High Prequency) waveband (42), connected to signal modulators for converting digital signals into radio ::; ;
signals and vice versa. One radio terminal is mounted in the fixed part of the parking building and the other in the revolving structure (11) of the car elevator. The elevator cabin has a command panel with buttons (49) for indicating the desired destination to the control panel, : . .::
with regard to the floor and the anular location of the specific space. There are also emergency stoppage but~
tons, a manual and automatic operator selector and.~
indicating lights. ;-~''''`,,' ~":' 2s 2 ~ ~ 2 ~
The safety control equipment is to be found within this subsystem, consisting of photoelectric cells on each of the elevator doors which avoids their closing if any obstruction exists, in which case they do not give the affirmative signal to the control panel for beginning the lifting and rotation movements; and, on the other hand, ;~
the starting controls of the tire trap actuators which, on being appplied, should similarly give permission to commence the lifting and rotation movements of the elevator cabin. ~;
DESCRIPTION OP r ; OPERATION OP T~ PRINCIPAL EKBODIN~NT
The operation described is following the sequence of entering the car park,--parking the car and, subsequently, leaving the parking building.
A11 cars will arrive at the ground floor entrance, -~
which can be one of the parking spaces (two or three), the sole purpose of which is to permit entrance. On stopping in front of the access barrier (37), the optical or loading sensors of same, they will detect their presence, and the automatic ticket issuer (33) will print the date and time ~-~
and, if desirable, the exact location of a vacant space to which the parking of the vehicle has been allocated, and will send an automatic signal to the logical control programmer (41) notifying the presence of a car which wishes to enter, which will look for a vacant space as 2t 12~
near as possible to the ground floor, in accordance with the period of time the vehicle i9 scheduled to be parked, which will be defined by the entrance space utilized. When the driver takes the ticket, the entrance bar o barrier t37) will be lifted to allow the car to enter the ground floor parking space acting as a passage, to then enter the elevator cabin. If the cabin is not placed in front of thi~ space, the ground floor protection barrier (32) will be in place, preventing the car from going farther. Once the elevator cabin (25) has been placed facing the access ~ -space, the barrier (32) will be vertically lifted, the -~
doors (31) of the elevator cabin will be opened, the tire traps (29) will be released, and a green light will go on ~`
the advi3e the driver that the car should enter the elevator cabin.
When the vehicle is temporarily parked in the cabin and there is no obstruction in the photoelectric cell of the door, the elevator operator can see from the command panel which of the pilotlights is lighted, indicating a vacant space on a specific level. On pressing the button which assigns the destination to which the vehicle should be taken, the operator gives an order to the logical control programmer (41) to commence the operation of the hydraulic pumps (19) of the car elevator (10), and the rotation movement of the platform will begin simultaneously, in~;
order to place the elevator in the required direction.
~ ~2:l~3 ~: ~
27 . -~efore beginning either movement and after having selected the car's destination, three simultaneous actions will take place: the first will be to draw back the piston of the safety barrier (32) on the ground floor, allowing it to fall, corresponding to the space where the car is located, and the safety device will be activated to :
prevent this rising solely by pushing same; the ~econd, that the traps (29) be applied to the front wheels of the :~.
car, and the third is that of shutting the sliding doors (31) of the elevator cabin. The confirmation of these three actions by the logical control programmer t41) will ~ ~;
give the command to begin opening the hydraulic valves connecting the hydraulic cylinders, and release of the ~ :
counterturn brake of the horizontal rotation gearmotors (12), commencing the vertical transfer and rotation of the elevator cabin through the control panel and the :
respective motors (19 and 24).
When the car elevator reaches its destination, the hydraulic valves of the oleohydraulic plant and the counterturn brake of the rotation motors (24) will be automatically applied and the tire traps (29) will be deactived one by one, the elevator doors will be opened (31) and the protective barrier (32) corresponding to the parking space of destination will be lifted, allowing the driver of the vehicle to park this in reverse in the assigned space with the assistance and help of the 2112 ~ 6~ 3 elevator operator. The vehicle should be driven to some stops placed on the floor to limit the perimetral transit passage of pedestrians in the area, whether or not they are coming for their vehicles.
Once the elevator cabin has been vacated, the elevator can be requested by the driver of another vehicle on the same, or another, floor, or by the driver of any vehicle which --is entering the parking building. The selection of priorities can be automatically programmed, or the elevator operator can decide manually, depending on the proximity of the space of the vehicle wishing to leave, or -~
the demand for the entry or exit of vehicles at a certain ~ -time of day.
In order for a vehicle to be able to leave the parking building, drivers should reach same by using the passenger ~ , ;
elevator (9) or the stairs (a), or the perimetral passages. Once within his vehicle, the driver should press the call button (46) for the elevator, located on the inside columns of the building at the height of the ! I driver's window. At the same time, the driver should star hi~ car and await the elevator. When the elevator call button is pushed, the signal is transferred through the -cable concentrators (44) and the data bus (43) to the logical control programmer (41), which will proce~s the ~-call and send a codified signal to the VHP radio equipment ~-~
which wlll, in wireless form, transmit this signal to the :~:. ~ ' ' '' : `
2 ~ ~ 2 :~ ~ 3 radio receiving equipment located close to the hydraulic system of the elevator. Signals are modulated and demodulated in order to be digitally fed to the car elevator control panel, in response to the request for positioning the elevator cabin (25), exactly opposite the parking space from which the call came. When the latter detects the call, the signal can be stored in the waiting line control or automatically or manually executed directly by the operator, 90 that the elevator ~ -descends vertically with a circular movement in th desired direction.
If the elevator reaches the desired level and place, the counterturn brakes will again be applied and the hydraulic valves closed, the protective barrier will be lifted and the green light of the elevator parking lights will be put on the indicate that the vehicle can drive into the elevator cabin. No elevator operation can be carried out while the car is blocking the light ray from the photoelectric cells, signifying that the doors cannot be closed. Once the vehicle is inside the elevator cabin, the motor should be kept runnning, but with the brake on the avert any movement, in addition to the restraining action of the tire trap described above.
The elevator, on descending to the ground floor, should revolve as necessary in order for the platform to remain in such a way that the front of the vehicle is painting 2~ ~ 21~3 ~:
towards the exit lane. Once the elevator has come to a ~ -standstill, the driver will be allowed to approach the payment booth, where he will deliver his ticket eo that the amount owing can be calculated.
The platform can revolve up to 360, however, control will be programmed 80 that the maximum turn in any direction either clockwise or counterclockwise, i9 Up to 180, in order to minimize the time and length of ;
the rotating movement.
As a part of the safety equipment operations is a startup by electrogenic alternate current generating equipment due to lack of power when a breakdown occurs in -the normal power supply, thus permitting the electrical and electronic equipment to continue in ;~
normal operation under normal operating conditions are -~
resumed.
Operation of the passenger elevator is normal and usual and it i9 not therefore described in this document.
ALT5~NATIVB ~KBODr~ENTS OF T8e INV~NTION
Flgures 12 and 13 represent an alternative embodiment of the radial parking system, in which the parking is similar to that previously described but with the difference that the 2~2:L~3 31 ~ ~;
elevator(10), instead of using cylinders with a single piston, use hydraulic cylinders (55) of the telescopic -~
piston type, thus reducing the length of piston (56) to half if there are two telescopic piston sections, or to one-third in the case of four telescopic piston~. These telescopic cylinders are in common use, for which reason no further details are given here. The rest of the components, both for the building, the elevator, the controls, etc., remain as in the previous description.
Figures 14 and 15 represent another embodiment of the radial parking system in which the latter is similar to those previously described, but with the variation that there is one hydraulic cylinder t57) instead of two, which is placed in the center of the elevator exactly below the platform, and is the same type as the telescopic cylinder with 2, 3 o 4 telescopic pistons. In this case, the piston would have a larger diameter, with a resulting larger pushing area if the same hydraulic pres~ure of the pump is maintained, and the length of the run will be equal to the length of the total height of the floors to which service is to be provided. The action of this piston is directed over the elevator cabin, and the ratio of run is, therefore, 1:1. For the present embodiment, pulleys (20), described in the previous versions, and the cables (34) which were connected to the structural girder (26) underneath the elevator cabin, are eliminated. The stroke 2l~2~3 :~
speed of the piston is, in this case, equal to the speed of movement of the cabin. The use of ~, ';,, ~ 3~

21L2:L~3 cylinders with telescopic pistons (58) in 3 or 4 sections i9 preferred, in order to shorten the lenght of the cylinder which should be partially embedded in a central hole within the rotatory foundation of the elevator, within which the cylinder will be housed and will rotate inside at the time the elevator, including tower and cabin, rotates in order to acquire the necessary loading o unloading position. The remainder of all compcnents, both of the building, the elevator, the instruments, etc., will remain unchanged in relation to the main embodiment of this invention.
The embodiment proposed in Figures 16, 17 and 18 i9 characterized by a parking elevator (10) being moved by four cylinders (60) with a single piece tubular piston (not shown), or by telescopic pistons (61, 62), as in the case shown, which can be two, three or four-stage. This alternative embodiment can be used to advantage in installations where the number of floors to be served by the elevator are numerous, and ~he lenght of the cylinder and the pistons must be limited. At the same time, this embodiment reduces the diameter required for each piston by duplicating the number if pistons for the same given weight and the same hydraulic fluid pressure. The elevator system consists of a system similar to that described in the preferred embodiment, where a rotatory tower (11), is - - .:
moved around a vertical center by two electric gearmotors ,.
2 ~ 3 (24), and which has a cabin (25) to lift the car3 through a hydraulic syctem (19) consisting of an oil tank, hydraulic pumps, valves and four cylinders with hydraulic pistons, normal or telescopic type, which are placed vertically at the sides of the cabin, two in vertical ascending form and two in vertical descending form. Each of the pistons has a metallic pulley (63) at the protruding end, where the cables of flexible ~teel in the form of a leaning S are housed, and which at one end are fixed to the base plate (64) of the inverted pistons (62) and, at the other, to the elevator cabin (25), 90 that the movement transmission ratio is 4:1; that is, for each unit of distance travelled by the pistons (61, 62), the cabin tra~els four units of distance. In other words, the distance travelled by the cabin and the speed of ascent and descent is four times greater than that of the pistons.
Another embodiment is shown in Figure~ 19, 20 and 21 in which the parking system is similar to those previously shown but with the elevator featuring two sets of mechanisms consisting of pulleys, cables, counterweights and hydraulic pistons, to obtain vertical movement transmission ratios of 6:1. The system consists of two sets of five grooved pulleys placed on the upper part of rhe elevator tower, at each side of the cabin; three ...-: : - .:
pulleys (66) are fixed at each side and the remaining two ~ ~
' ~
~ ~' 3~ 2~ 12~3 (67) are movable, and move vertically up or down; each of the pulleys having free rotatory movement. The movable pulleys ~67) are linked by a metallic structure or member (68), which keeps them separated and includes at its ends two sliding guides for pulley rails (69), which will keep the movement straight throughout the journey of ascent or descent, which will only be one-sixth of the vertical journey of the elevator cabin (25). The rails are suitably supported and spaced from the secondary structure (11) of the elevator. Two counterweights (70) are hung from the center of the metallic structures (68) of the pulleys, the purpose of which is to reduce the power necessary for raising the elevator cabin plus the weight of the cars and their occupants. The total weight of the two counterweights will in fact be approximately equal to between 120% and 140% of the dead weight of the cabin, plus the elevator load. m e mobile pulleys and the fixed pulleys are connected as shown in figure 19, by means of continuous flexible metal cables (71) in the form of a vertical zigzag with 6 steps, one end of the cables being fixed to the structure of the elevator tower (11) and the other to the elevator cabin. ~3elow the counterweights are two cylinders with oleohydraulic pistons (72), which are supported by the elevator structure (11), and their pistons (73) wor~ vertically underneath the counterweights. mi9 results in the following advantages~
~ .
.~
21 ~2 1~ .~
first, a ratio of cabin travel as compared with the hydraulic piston travel i9 obtained of six to one;
secondly, the counterweights are used to raise the elevator cabin and load, and the hydraulic pistons are only used to lift the counterweights and thus lower the elevator cabin. In fact, the form of operation consists of whether or not the cabin is loaded, oil i9 drained from the hydraulic cylinders, allowing the pistons to retract and lower the counterweights, 90 that the steel cables move one way only and the elevator cabin rises.
When it is wished to lower the cabin, then the hydraulic pump or pumps of the station (19) will inject oil to the cylinders, resulting in the pistons extending beyond the cylinders and pushing the counterweights upwards, thus raising the mobile pulleys, and the cables will move in the opposite direction 90 that the elevator cabin descends.
This embodiment can result in substancial saving in the cost of the elevator mechanisms, since the needs of the oleohydraulic mechanisms is considerably reduced, and also gives us relatively large elevation distances with relatively small pistons.
The embodiment proposed in figures 22, 23 and 24 corre~
sponds to a parking system similar to those previously described but with the difference, as in the previous case, that the car eleva~or has a cable system (71), fixed 21321~3 pulleys (66) and hydraulic cylinders (72), with a transmission ratio of 6:1. In contrast to the previous embodiment, in this case there are no counterweights to raise the elevator cabin (25), and the pi~tons act in the opposite direction, pushing the mobile pulleys downwards to increase the distance separating them from the fixed pulleys. In this case the manner of operation is different from that described in the previous embodiment since, in order to raise the elevator cabin plus the load, hydraulic oil would have to be pumped to the cylinders (72), leading the pistons (73) to project outwards and the mobile pulleys (67) on each side of the elevator to descend, in-creasing the distance between the mobile and fixed pulleys 90 that the cables (71) move to one side, and the elevator cabin (25) rises. On supressing the hydraulic pressure inside the cylinders (72), the pistons contract and the mobile pulleys go up, pulled by the cables, due to the weight of the cabin and load transported. The advantage of this system is a reduction in the overall weight of the e evator, maintaining relatively-small cylinders with very short runs due to the 6:1 ratio.
In either of the foregoing embodiments, the present invention can consists of two or more adjacent parking towers, utilizing the same passenger elevator services and stairs, with the possibility of transferring vehicles from '''"'~''' '' ' .,, -'-39 ~ 2 1 ~ 3 ; ,::
one building to another should any operational problem arise in one of the car elevators.
According to the parking system embodiment represented in figures 25, 26 and 27, the car elevator (110) consists of a supporting structure (111), in the form of a hollow paralelepiped, with a 3tructural square containing diagonals and a center plate (112) on the upper face, hanging from the steel cables (113) which hoist the elevator cabin. Four structural legs (114) extend from the vertexes of the square which, in turn, support the lower face of the structure, which i9 similar to the upper face described above, but with the addition of a structural square (115), which sexves to support the rollers (116) the purpose of which i~ described below. An axial load bearing hangs from the central part of the lower face, serving as a pivot for the circular movement of the elevator platform (118).
The metallic sheeting platform (118) is circular and has an axis in the form of a solid shaft in it~ center and .,, :. .
lower parts, and is placed on the lower face of the elevator structure and withi~ the vertical legs forming the edges of the elevator structure. The platform (118) is reinforced in its lower part by two concentric circular channela (119, 119'), one channel (119) being placed within the periphere of the platform and the other channel (119') appproximately in the middle of the platform ~ "'.';
2~12~6'~
radius, the purpose of these channels being to stiffen the platform and to serve, at the same time, as a taxiway for the turning rollers (116).
The turning rollers (116) will be placed in a minimum of twelve, and consist of rubber coated steel rolllers which contain a solid metallic shaft supported by two side bearings. Each roller group is suitably placed on the lower structure of the elevator (figure 27), and fixed by means os screws and nuts in a suitably angle position.
By the help of the central axial bearing (117) and the loading rollers ~116), the elevator platform can turn 360 by the action of two motors (120), which are vertically placed on the lower part of the platform, suitably fixed to the lower structure of the elevator (110). The two motors have pinion-type gears attached which, on turning, displace a sprocket (121) which is placed on the outside part of the internal reinforcement ring of the platform (118)l anda therefore turn the platform. The motors (120) consist of an electric motor which receives specific signals from the control system in order to adopt a position previously selected by the master control of the logical control programmer. Having two motors, the turning system becomes redundant, thus increasing its reliability to 200%, and allowing a motor to turn the platform in one direction and the other in the other direction, one motor being idle while the other is working.

The hoi~ting motor of the car elevator (122) i placed on the upper part of the parking center, and consists of the conven~ional parts of any passenger elevator, but with a larger capacity. The hoisting mechanism of the elevator consists of a gearmotor, with reversible action, traction pulleys for the cables, counterweights and electrical call, destination, emergency stops, alarm, etc., controls.
In contrast to other conventional elevators, this possesses additional turning controls as described in the preceding paragraph.
As in the foregoing embodiments, the signalling and control system of the parking 3ystem forms a substantive part of same, since it is this which allows semiautomatic and safe operation throughout the system.
Another embodiment of the present invention is shown in figures 28 and 29, consisting of two adjacent towers (A, B) for radial parking, the height and distance between elevators of which is suitably modulated in such a way that the horizontal distance between the elevator centers i8 an lexact multiple of the vertical distance between every two floors, and which has the speciality that the elevator has continuous action in a single direction, having a fixed number of platforms (137), as shown in figure 29. For an arrangement of two towers with 3even levels, there are eight platforms (137) joined by metal chains (138), placed at the ends of a diametral cord. Each ",,",.
21~ 3 of the platforms has its own rotating movement to place the platform at the de~ired angle with respect to the parking spaces for the cars. The plataforms joined by the traction chains (138) ascend by an elevator shaft and subsequently, when they reach the top floor of the parking building, move horizontally over a roller table (139), and then de~cend vertically within the elevator shaft of the ~ ~t adjoining tower, finally moving horizontally in the opposite direction over a second roller table (140) to close the cycle of movement. The chains are moved by racks (141) located in the four vertexes of the elevator's motive system, three of the racks being motorized, with the exception of the lower pulley located where the platforms descend. These racks (141) are impelled by electrical gearmotors of the capacity necessary to carry out the work of lifting the platforms or the movements over the upper and lower roller tables. The work of each motor i9 synchronized with the other two. Conveyance of the electromotive power necessary for the turning motors of the platforms, is carried out by trolleys located on the lateral guides of the elevators and at one end of the roller tables. The control signals to establish the ~ ~
startup, positioning and stoppage of the platform rotative ~ -movement motors is of the shortwave radio type, or an optic sensor with the breadth and lenght of a regulated -wave. The purpose of operating in this embodiment is to .: . .' 43 211~i~i3 :~
have a greater capacity for the entry and exit of cars from the parking system.
The automatization degree is complete, each platform stopping automatically on each floor for a preestablished period of time, allowing drivers to place their cars in the center of elevator platforms through luminous traffic signal~ and audible instructions, following which the platforms descend vertically and turn with a rotatory movement until they find the preselected position and level, to descend radially to the desired parking space.
The exit operation of the cars will be inverse to that of their entry, but with the same control and protection philosophy.
Regarding the embodiment of figures 30 to 34, the car elevator consists of a supporting, rotating and guiding structure formed by a lower metallic table (212), supported by six metallic rollers (213), which turn over a static circular rail (214) anchored to the parking building foundations (201). At its central part, the table (212) has a turning shaft (215), permitting an angular displacement of up to 360, consisting of a shaft which turns within one or several bearings which are rigidly supported in turn by a concrete jackbits which form part of the foundation. Four vertical metallic columns (211) are placed on the swivel table suitably stiffened with secondary structural elements (216) to reduce their .;.

slenderness ratio in the case of relatively high elevators. The four columns (211) serve also as support for fixing the guide rails (217) of the elevator, and the guide rails of the counterweight (235). An engine room is located in the upper part of the four columns (218), containing a traction engine (219) for elevator, together with the pulleys (229) necessary for same. An upper center of turning (221) is installed at the central part of the engine room, which also has a shaft and one or more bearings, fixed to structural girders (222) forming a cross-shaped structure which i9 linked with the internal columns (202) of the building, providing the uppermost center of turning of the elevator.
At the lower part of the turntable (212), two electrical gearmotors (224) are provided, suitably attached to the structure, with connected pinion-type gears (260) which are, in turn, duly geared in a circular ring (223), which is rigidly supported over the reinforced concrete foundations (201) of the parking building. These gearmotors on being placed in operation, will result in the rotation of the elevator (210) as a whole with the Yupporting structure (211), (212), (216), (21~), (219) and (225). The use of two gearmotors has been chosen for the purpose of having a balanced turn at the opposite ends of the ring. The motive elements consist of an electric motor which receives precise signals from the control system, to 2 1 1 2 ~
adopt a position which has been preselected by the master control of the logical control programmer, clockwise or counterclockwise, allowing the turn to take place in the shortest direction between the original cabin position ~ ~ ~
(225) and the final destination position. ;~-The equipment for hoisting the cabin vertically is of traditional elevator type, consisting of a gearmotor (219) ~ `
with a reversible traction pulley, diverting pulleys (220), traction cables (234), cable pulleys (if the traction ratio is 2:1), a counterweight (235) and the necessary fittings to fasten same. ;
Shock absorbers (236) are placed on the upper part of turntable (212), these being spring and oil absorbers, for -the cabin (225) and counterweight (235), for the purpose of progre~sively reducing the impact of a sudden descent ;~
of the elevator cabin.
The counterweight will move vertically up or down in accordance with the relative cabin position, for the purpose of reducing consumption of the power required to lift the cabin and the corresponding load of the car plus it~ occupant~.
With regard to figure~ 35, 36 and 37, these represent a new alternative embodiment of radial car parking, wherein the rotatory elevator is operated by a single hydraulic piston type (251) which will be placed in the lower part of the cabin. This type of elevator is now in common use, .~.
21~2~L63 and their working is not therefore described in detail, mentioning the main parts and the modifications necessary for them to be utilized for this specific purpose.
The revolving structure of the elevator ~211), in addition to the turntable (212), the rollers (213), the circular rail (214), the lower turn shaft (215), the guiding rails (217) and the upper center of turning (221) will remain unchanged. In addition, for this embodiment of the engine room (118), the traction machine (119) and the pulleys (120) are not needed. Instead of the traction equipment, a hydraulic piston (251) fixed to the lower part of the parking lot is included, for which purpose it has a tubular cylindrical casing (250) which will be embedded in the ground and will have the same length as the hydraulic elevator piston (251). The casing (250) will contain the earth and water of the phreatic levels and act as a receptacle for the hydraulic piston (251). The piston is assembled on the turntable (212) and housed within the casing (250), without having contact with the casing because the piston will have a rotatory movement. An important part of the hydraulic piston is its stem, which move~ up to down supporting the weight of the cabin and the weight of the car on applying the hydraulic pressure obtained from the hydraulic pumps (253) which, together with the hydraulic fluid tank (254), are also mounted on the elevator turntable (212).

The control panel will also be similar, but instead of commanding the electrical hoisting motor, will now start the hydraulic pumps in order to increase the pressure or the volume of the hydraulic fluid in the piston, and make the elevator ascend, or reduced these and send the hydraulic fluid coming from the piston to the storage tank, thus forcing the elevator cabin to descend.
Even though the invention has been described in its preferred embodiments, it should be emphasized that other variations can result from the foregoing concepts which wlll be obvious in the light of the foregoing description, which should be taken as an example, with no limitation

ABSTRACT OF TH~ INVBNTION
This invention refers to a multiple parking system of a radial and mechanized type, which is highly efficient since it requires very little space for circulation, as ~ ;
compared with the area used specifically to park the cars. ~ ;-This allows for a better use of urban space, efficient operation and a reduced investment cost. --~AC~GRO~ND OP TEE INVENTION
Field of the Invention This invention refers to a mechanized, radial type parking system, allowing twelve vehicles to be parked per floor without the need of areas for maneouvring or circulation, and which applies to any urban area, especially where the land is scarce and expensive. The result is a high level of efficiency and density for vehicle parking as compared with the overall land and building area. A parking lot of this type is described in the applications for Mexican patents Nos. 927515 and 936173, belonging to the same titleholder of the present -;
patent application. ~
Prior Art Previously-existing parking ~y~tems are very varied, and can be classified in non-mechanized and mechanized categories. The first provide ease of circulation to allow vehicles to move from the entrance to the parking space, whether located on a single ground-level floor, or on a higher floor where access is by means of a sloping ramp, or where the parking spaces form part of such ramp. These parking lots are characterized by low efficiency, high investment costs, the need for a large land and construction area, and low operating and maintenance costs. The ~econd type of parking lots (mechanized) are characterized by a higher level of efficiency, ranging from those with a low level of sophistication which combine an elevator mechanism with circulation lanes, to fully mechanized systems where the vehicles are suspended in the lifting equipment itself or in vertically-placed ~ -niches. Use of the latter has been extremely restricted and for very specific applications, due to their high investment cost. -~
The foregoing demonstrates the need for designing and building parking systems which combine the following factors of primary importance~
a) An efficient use of urban land 3 21~2~3 :~ ~
b) Vertical construction, to allow greater parking capacity c) The requirement for land or reduced dimensions d) A low investment cost e) A low operting cost f) High efficiency in connection with the area needed for parking a car vs. the overall construction area g) Reliability h) Low maintenance i) Low live weight v9. dead weight ratio of the ~ ~
parking sys~em ~ 9 j) Easy operation k) Modular construction 1) A capacity which can be expanded m) Recovery of investment plu9 operating costs A radial mechanized parking system takes the foregoing design factors into consideration, providing potential ~;

OBJECTS OP T~E INVeNTION
The object of the present invention is, therefore, to provide parking for cars in a mechanized, radial-type system which is efficient, novel, functional and extremely economical for installation in urban areas.
4 2l~2~l~3 ~:
The other object of the present invention is to optimize the use of urban land areas by parking vehicles on two or more floors.
Another object of the present invention is to eliminate car circulation, ascent and descent ramps and lanes, in order to better utilize the available construction area of the parking system.
An additional object of the present invention is to have a car-lifting system which, once vehicles are lifted from one level to another, revolves on its own access to allow them to be placed at a suitable angle for ascent and descent.
Another object of this invention is to provide parking where the dead weight of the building is relatively low when compared with the live weight of the cars ad their occupants, in order to reduce the investment cost~.
Yet another object of this invention is to provide a mechanized and semi-mechanized system to work faster in placing the cars, and which operates with a high degree of security for the occupants, the operating personnel, the vehlcles and the parking system itself. ;~-Finally, a object of the present invention i9 to provide a modular parking system the capacity of which can be increased in accordance with the needs of each specific case, and which is easily made, put together and operated.
-~
2112'~ 3 ', The foregoing objects become reality with a new parking system of the radial, mechanized type, consisting basically of a foundation slab of reinforced concrete which will serve as a supporting platform for the structure of the building, as well as, serving as the lower floor of the parking system; a metallic or concrete structure with radial girders sustained by suitably~
distributed columns for supporting both the dead weight of the building and the live weight of the cars and their occupants; a revolving elevator of a hydraulic or hydraulic with cables type in the center of each tower which, in addition to hoisting the vehicles, revolves around a central axis to acquire any of twelve preselected positions within 360, a signalling and control system which allows the operator to identify unoccupied spaces and make the elevator cabin stop vertically on the desired floor and horizontally in the required position, while at the same time allowing safe operation of the elevator in order to prevent any movement or rotation while a vehicle i8 being lifted or lowered to the elevator cabin.
More specifically, the parking system of the present invention consist of a cylindrically-shaped building of two or more floors in the form of a circular crown, placed one obove the other in perfect alignment, in such a way that its structural elements coincide when seen from above. The floors are supported by columns in such a way 21~ 2163 that each floor has the capacity to hou~e twelve radially-placed cars.
A car elevator is placed in the center of the circular crown of each floor, which will raise or lower these to each floor or from each floor to ground level, and will position them by revolving on its central axi~ in the ascent or descent angle of the elevator required, according to the relative position of the parking space or point of exit. A feature of this elevator is that, in addition to its transfer movement, it also rotates the structural guide tower, the carlift and hydraulic lifting system. The elevator consists of a vertical revolving structure which turns- on its vertical longitudinal axis and which, in its lower part, serves as a support for the hydraulic lifting equipment and as a guide for the lifting cabin which runs vertically within the guide bars of structure itself. The metallic structure consists basically of a revolving table in the form of an inverted pyramid which supports two structural legs throughout the vertical length of the entire elevator and the hydraulic equipment, and whose upper extremity is another pyramid.
Two central axis (an upper and a lower placed on the vertexes of the pyramids) formed by ball bearings, make up the revolving axis of the structure, the cabin and the hydraulic equipment by the action of an operator on the lower part of the table who, through a crown gear, a 2 ~ ~ 2 ~
pinion and an electrical gearmotors, starts the rotatory movement which will permit the radial positioning of the elevator cabin in each of the twelve parking places corresponding to each of the floors.

In order to explain better and clearly the new parking system, the following description has been divided into chapters, each of which referred to a fundamental part of the parking system.
PAR~ING ~UI~DING
The parking building consist~ of a vertical structure, of either reinforced concrete or, preferably metallic, which is usually cylindrical in form with several floors, which can be from two to an indefinite number, in accordance with the special conditions of each case.
The building structure can be supported by foundations, depending on the specific conditions of the project, the height of the building, the overall weight, the 90il conditions, etc. These foundations can take the form of an extended slab of reinforced concrete (1), isolated shoes or continuous foundations in the form of concentric circular rings.
Columns ~2) are placed on the foundation slab to support ! ` I the first floor and the primary girder3 (3~, which are placed in radial form, the interior end of each radial girder (3) in cantilever, since there is no center column as this would hinder the transit of the cars. All the radial girders on each floor(3) shown in figure 3, finish and are joined in a circular ring or a structural dodecagon (4), which limits the central space where the ~' ' 14 2 ~
car elevator (10) circulates. Secondary and terciary girders (5,6) are connected to the primary girders in transversal form in order to provide sufficient rigidity and support for the floor (7) of each parking level.
The floor on each level can be made of reinforced concrete slabs or, preferably, steel sheeting (7) of a caliber suitable for the live weight it must support, being in the form of a natural U and an inverted U fo form a continuous accordeon, thus achieving a substantial reduction in the weight of each level, with a reduced dead weight and a lower investment cost.
The building will have stairs (~) and an elevator (9) for parking users, to be placed as shown in figures 1, 2, 3 and 4.
~Q~IPM D T
The equipment will consist basically of two items, each covering various components of the system. The first item is the car elevator (10), in its various embodiments, and the signalling and control system (figure 11).
MFC~ANICAL ~Q~IP~WT FOR LIFTING AND POSITIONING CARS
The car elevator (10), as its name indicates, i9 intended to lift or lower vehicles to each of the operating levels and place them in an exact entry or exit position, complementing the effects of the transfer and rotation required for car placement, and reducing manouevres to a minimum. The car elevator consists of a supporting, ' ~ ~'"' 2~1`2 L~
rotating and guiding structure (11), as shown in figures 5, 13, 15, 17, 20, 23, 25, 29, 32 and 36 related to each ~
embodiment of the elevator, which is formed by two ::
structured metallic columns (11) joined only at top and ~ .
bottom which are vertically parallel and serve as a guide for the elevator cabin (25). The lower part of the :--~
structure (11) ends in a kind of inverted pyramid (12) (partially shown), where the lower corner acts as a .. . .
rotating support for the entire tower, including the elevator cabin and hydraulic equipment, utilizing an axial type bearing (15) which i9 firmly attached to the foundations on one side, and to the lower inverted pyramid of the structure also -ends in a kind of structural pyramid with a transversal element which joins the two legs of the structure (11) guiding the elevator, the pyramid having another bearing, in this case for axial type loads, in the center o vertex (21), the lower part of which is joined to the elevator tower (11), while its upper part is connected to four horizontal girders (22) forming a cross- shaped ! member.i Girders (22) are, in turn, attached to four internal columns (2) of the parking building (figure 4), ~in order to keep the vertical rotating shaft of the elevator itself centered and properly aligned. The two structural metallic columns are composed of primary elements (11), which form a vertebral column in conjunction with secondary elements (13), which will ~' ', ' '' 16 21~ 2~3 increase their rigidity by providing better proportions, above all in parking system where it is necessary to install a greater number of floors. The primary vertically- placed structural elements (11), serve as support for installing the vertical parallel rails (17), which will guide the ascent or descent of the elevator cabin (25). The secondary elements (13), aside from providing additional rigidity to the primary elements, allow the secondary guiding rails (14) to be stiffened for the upper pulleys (20) of the pistons (36) of the elevator's hydraulic system, avoiding in this way any possible misalignment in the vertical piston stroke on leaving or entering the cylinders (35).
The lower part of the elevator structure is also intended to house the elevator hydraulic system (19), consisting of the oleohydraulic tank, the hydraulic pressure pumps, the control valves and the cylinders (35), together with their hydraulic pistons t36) and, on the other hand, houses two electrical gearmotors (24), which are vertically placed and which at their ends, protruding from the rotor shaft, are connected by two pinion-type gears which turn around a circular crown (23) of straight gears which are firmly attached to the concrete foundation (1) of the elevator itself. The drive of the two geramotors will result in the entire elevator (10) as a whole (metallic structure, cabin, hydraulic system, etc.) turning around the vertical shaft driven by the movement of the electric gearmotors (24) around the crown of gears (23). The motive elements consist of electric motors which receive a precise signals from the control system in order to adopt a position preselected by the master control of the logical control programmer, clockwise or counterclockwise, permitting a turn in the shortest direction between the original cabin po~ition and final destination position.
The oleohydraulic equipment of the elevator consists basically of the following essential elements: One or two metallic tanks (19) for storing and returning the system~s hydraulic oil; one or two hydraulic pumps activated Dy electric motors (not shown in the drawings), which are placed inside the oleohydraulic tanks with a submerged type installation, and are moved by one or two electric motors (not shown) which, on functioning, inject the hydraulic oil through the control valves (not shown) towards the lower part of the hydraulic cylinder (35) placed on each side of the cabin ~25), and running parallel to the metallic structure (ll) and the guide rail (17). Two pulleys (20) are placed on the upper ends of the cylinder pistons (36), said pulleys supporting the elevator cables (34), and being fastened at one end to the structural base of the revolving tower (12) and, at the other end, are connected to the elevator cabin (25). The electric actuation of the hydraulic pump motors results in ~ 18 2~2~3 the oil from the storage tanks being injected at high pressure at the base of the hydraulic cylinders (35), which results in the pi~tons (~6) being vertically displaced upwards and outwards, 90 that the metallic cables (34) fastened to the elevator cabin are displaced in one direction to that the cabin itself rises with a run equal to twice the stroke of the hydraulic pistons. When the electric motors of the pumps turn anticlockwise, they will ab~orb oil from the hydraulic cylinders and transfer this to the storage tanks, retracting the pistons and displacing the metallic cables anticlockwise, 90 that the elevator cabin descends.
The elevator cabin (-25) consists of a box of metallic sheeting in parallelepiped form, suitably reinforced by structural elements (26) to allow it to be hoisted from the transversal ends, preventing their permanent deformation. Some guides (27) are placed on the upper and lower edges of the cabin, which can be the sliding shoe or revolving bearing type which engage the guide rails (17) on three sides, allowing the cabin to move vertically, perfectly guided, thus achieving the de~ired alignment of the cabin (25) throughout its vertical journey. Two metallic guides (28) are placed inside the cabin for car tires, 80 that these enter or leave the elevator in the direction and with the alignment required for their suitable functioning. At one end of the elevator guides .~ .
~F~ ~
2~2~3 ; ~ ::19 . ' .
(28), automatic traps (29) are placed for the front wheels of the vehicles, in such a way that when they are actived the movement of the wheels i9 hampered either accidentally or on purpose. The traps (29) consist, for example, of four structural steel plates or angles placed in reverse, which slide or turn by means of a gear and lever mechanism, which is moved by a mechanical actuator (30), with an electrical or reversible hydraulic motor, 90 that the angle wedges or plates in front of and behind the `~
front wheel~ of cars to prevent their moving when the traps are applied, or are withdrawn by either sliding or turning a center at one end to withdrawn from the path of the vehicles and free the tires, allowing them to move over the guides (28) of the elevator cabin. Bipartite metallic doors (31) will be placed at both ends of the elevator cabin, which slide towards each side of the -~
cabin. The doors are electrically operated by a mechanism which is actived once the elevator cabin has been vertically and angularly placed in front of each of ;~
parking spaces. `
Protective barriers (32) are placed on each floor of the parking building, around the car elevator shaft, for the purpose of preventing any person or car from coming too ~ -close to the open elevator shaft. These barriers are folding and are raised upwards by pushing a stem (33), which is moved automatically by an extension mechanism of '.`: ~.,', ' -; '' :' 21~2~
the elevator itself, connected to the actuator (30) of the elevator traps.
Two spring shock absorbers (18) are placed on the upper part of the turntable (12), the purpose of which is to progressively reduce the impact of a sudden descent of the elevator cabin. ~
INSTR~MENTATION AND CONTROL EQ~IPMENT --The signalling and control system of the parking system forms a basic part of same, since this permits the semiautomatic and safe operation of the entire system. A
more advanced version of the same is the fully automatic control system, which is described as embodiment hereafter.
The gèneral configuration of the semiautomatic control system for the parking system takes various forms into consideration, based on the basic equipment, the sophistication of which can increase to the point where a fully automatic system is obtained.
The basic equipment consists of the elements shown in figure 11. The instrumentation and control system consists basically of three interconnected subsystems to provide the necessary operating and safety conditions, which are:
a) Subsystems for entering, paying and leaving the parking building. -b) Subsystem for occupying and calling the elevator.
-.;--,....
2 ~
c) Subsystem for controlling and raising the elevator cabin, together with the latter's security system.
S~9SYSTEM FOR BNTE~NG, PAYING AND ~EAVI~G TEE PARRING.
This system consists of one, two or three folding access barriers (37) and conventional ticket machines (38), which will have car presence detectors which permit these to enter when there are space3 available, or refuse entry when the signal of the Logical Control Programmer shows that there are no places available. On another aspect, this system includes the conventional collection system (39), which consists of a parking time reader which issues the cost when the time recorded is multiplied by the unit cost of the time unit. Both items of egiuipment, that for issuing tickets and that for reading and invoicing, can be replaced by acces3 and exit equipment which utilized plastic cards with magnetic ;~
tapes, achieving the same efect.
The system described here is connected to a logical control programmer and a conventional personal-type computer (40) which, in turn, forms part of the elevator operation and call sybsystem.
If the ticket issuer i9 of the bar code type, showing date, hour and minute, a car reader will be installed which will calculate the length of stay and the invo~icing.
2~ ~2~
EL~VATOR O~BRATION AND CALL SUBSYSTEM This system consists basically of a Logical Control Programmer (41) with suitable entry and exit signals, for receiving occupation ;~
signals from each parking space, the permanent location of the elevator cabin, and to give the command signal to the elevator to attend a request. The Logical Control Programmer will have doors to connect the personal computer, which will have doors occupancy conditions and the calls pending answer on the monitor screen, together with the possibility of calculating invoicing and showing the operation acrual. It will also show autodiagnoses of the status of different system elements.
The Logical Control Programmer has additionala -~-communication ports for connecting a portable programming computer, the card reader, a VHF frequency radio modem (42), the ticket issuer and the data channel or "bus"
(43), obtained from the cable concentrators (44) on each floor of the parking building.
There are two primary elements in each parking space which will transmit signals to the logical control programmer. The first are photoelectric cells (45), which will detect the presence or absence of a car in each space, showing their availability for occupancy, which will be located by means of the logical control programmer to a specific space as a possible destination of the elevator to unload cars. The second will be the call 2 1 1 2 1 ~
.,:, 23 ~ :
buttons (46) located in each parking space which, on being pu~hed, will request the presence of the elevator at the correct floor and in the correct radial position, to permit the exit of a specific car from the parking building. Both the photoelectric cells and the call -buttons will be connected to the logical control programmer by means of cable concentrators (44), which will clas3ify the signals to identify their origin and send them through a data bus to a signal converter (47) which will, in turn, be connected to the logical control programmer.
EL~VAT~R CABIN ROTATION AND RAISING CONTROL SU~SYS N AND
SAFBTY SYSTE~ T~FRBFOR .
The purpose of this invention is to command the actions of the elevator. Some of these ar~ of the conventional type, such as the opening and closing of doors, the detection of door obstructions, the raising and descent of the elevator :-cabin, the closing of the hydraulic valves, the sequential registration of calls requesting the elevator and the floor destination to which the elevator should be sent.
Others are completely innovative, such as th transmission ~: .
by VHF bandradio (42) of requests from the different users located in parking space, the rotation of the elevator around its vertical shaft to place itself in a required radial position, application of the counterturn brake to avoid horizontal rotation,the permanent location of the 2~2~63 cabin tran~mitted to the logical control programmer and application of the elevator cabin tire traps, among others.
The control equipment consists of the conventional equipment used for elevators, which is not described since it is in common use, to which controls similar to that of : :
vertical elevation will be added to achieve the startup, ;--acceleration, deacceleration, stoppage and braking of the angular rotation motors of the elevator cabin by means of the speed reducers (24), which act on the gear crown (23).
In order to transmit the orders coming from the parking system, photoelectric cells (45) and call buttons (46), a cordless data transmission will be utilized, using a pair of "duplex" type transmitters/receivers on the VHF (Very ~- .
High Prequency) waveband (42), connected to signal modulators for converting digital signals into radio ::; ;
signals and vice versa. One radio terminal is mounted in the fixed part of the parking building and the other in the revolving structure (11) of the car elevator. The elevator cabin has a command panel with buttons (49) for indicating the desired destination to the control panel, : . .::
with regard to the floor and the anular location of the specific space. There are also emergency stoppage but~
tons, a manual and automatic operator selector and.~
indicating lights. ;-~''''`,,' ~":' 2s 2 ~ ~ 2 ~
The safety control equipment is to be found within this subsystem, consisting of photoelectric cells on each of the elevator doors which avoids their closing if any obstruction exists, in which case they do not give the affirmative signal to the control panel for beginning the lifting and rotation movements; and, on the other hand, ;~
the starting controls of the tire trap actuators which, on being appplied, should similarly give permission to commence the lifting and rotation movements of the elevator cabin. ~;
DESCRIPTION OP r ; OPERATION OP T~ PRINCIPAL EKBODIN~NT
The operation described is following the sequence of entering the car park,--parking the car and, subsequently, leaving the parking building.
A11 cars will arrive at the ground floor entrance, -~
which can be one of the parking spaces (two or three), the sole purpose of which is to permit entrance. On stopping in front of the access barrier (37), the optical or loading sensors of same, they will detect their presence, and the automatic ticket issuer (33) will print the date and time ~-~
and, if desirable, the exact location of a vacant space to which the parking of the vehicle has been allocated, and will send an automatic signal to the logical control programmer (41) notifying the presence of a car which wishes to enter, which will look for a vacant space as 2t 12~
near as possible to the ground floor, in accordance with the period of time the vehicle i9 scheduled to be parked, which will be defined by the entrance space utilized. When the driver takes the ticket, the entrance bar o barrier t37) will be lifted to allow the car to enter the ground floor parking space acting as a passage, to then enter the elevator cabin. If the cabin is not placed in front of thi~ space, the ground floor protection barrier (32) will be in place, preventing the car from going farther. Once the elevator cabin (25) has been placed facing the access ~ -space, the barrier (32) will be vertically lifted, the -~
doors (31) of the elevator cabin will be opened, the tire traps (29) will be released, and a green light will go on ~`
the advi3e the driver that the car should enter the elevator cabin.
When the vehicle is temporarily parked in the cabin and there is no obstruction in the photoelectric cell of the door, the elevator operator can see from the command panel which of the pilotlights is lighted, indicating a vacant space on a specific level. On pressing the button which assigns the destination to which the vehicle should be taken, the operator gives an order to the logical control programmer (41) to commence the operation of the hydraulic pumps (19) of the car elevator (10), and the rotation movement of the platform will begin simultaneously, in~;
order to place the elevator in the required direction.
~ ~2:l~3 ~: ~
27 . -~efore beginning either movement and after having selected the car's destination, three simultaneous actions will take place: the first will be to draw back the piston of the safety barrier (32) on the ground floor, allowing it to fall, corresponding to the space where the car is located, and the safety device will be activated to :
prevent this rising solely by pushing same; the ~econd, that the traps (29) be applied to the front wheels of the :~.
car, and the third is that of shutting the sliding doors (31) of the elevator cabin. The confirmation of these three actions by the logical control programmer t41) will ~ ~;
give the command to begin opening the hydraulic valves connecting the hydraulic cylinders, and release of the ~ :
counterturn brake of the horizontal rotation gearmotors (12), commencing the vertical transfer and rotation of the elevator cabin through the control panel and the :
respective motors (19 and 24).
When the car elevator reaches its destination, the hydraulic valves of the oleohydraulic plant and the counterturn brake of the rotation motors (24) will be automatically applied and the tire traps (29) will be deactived one by one, the elevator doors will be opened (31) and the protective barrier (32) corresponding to the parking space of destination will be lifted, allowing the driver of the vehicle to park this in reverse in the assigned space with the assistance and help of the 2112 ~ 6~ 3 elevator operator. The vehicle should be driven to some stops placed on the floor to limit the perimetral transit passage of pedestrians in the area, whether or not they are coming for their vehicles.
Once the elevator cabin has been vacated, the elevator can be requested by the driver of another vehicle on the same, or another, floor, or by the driver of any vehicle which --is entering the parking building. The selection of priorities can be automatically programmed, or the elevator operator can decide manually, depending on the proximity of the space of the vehicle wishing to leave, or -~
the demand for the entry or exit of vehicles at a certain ~ -time of day.
In order for a vehicle to be able to leave the parking building, drivers should reach same by using the passenger ~ , ;
elevator (9) or the stairs (a), or the perimetral passages. Once within his vehicle, the driver should press the call button (46) for the elevator, located on the inside columns of the building at the height of the ! I driver's window. At the same time, the driver should star hi~ car and await the elevator. When the elevator call button is pushed, the signal is transferred through the -cable concentrators (44) and the data bus (43) to the logical control programmer (41), which will proce~s the ~-call and send a codified signal to the VHP radio equipment ~-~
which wlll, in wireless form, transmit this signal to the :~:. ~ ' ' '' : `
2 ~ ~ 2 :~ ~ 3 radio receiving equipment located close to the hydraulic system of the elevator. Signals are modulated and demodulated in order to be digitally fed to the car elevator control panel, in response to the request for positioning the elevator cabin (25), exactly opposite the parking space from which the call came. When the latter detects the call, the signal can be stored in the waiting line control or automatically or manually executed directly by the operator, 90 that the elevator ~ -descends vertically with a circular movement in th desired direction.
If the elevator reaches the desired level and place, the counterturn brakes will again be applied and the hydraulic valves closed, the protective barrier will be lifted and the green light of the elevator parking lights will be put on the indicate that the vehicle can drive into the elevator cabin. No elevator operation can be carried out while the car is blocking the light ray from the photoelectric cells, signifying that the doors cannot be closed. Once the vehicle is inside the elevator cabin, the motor should be kept runnning, but with the brake on the avert any movement, in addition to the restraining action of the tire trap described above.
The elevator, on descending to the ground floor, should revolve as necessary in order for the platform to remain in such a way that the front of the vehicle is painting 2~ ~ 21~3 ~:
towards the exit lane. Once the elevator has come to a ~ -standstill, the driver will be allowed to approach the payment booth, where he will deliver his ticket eo that the amount owing can be calculated.
The platform can revolve up to 360, however, control will be programmed 80 that the maximum turn in any direction either clockwise or counterclockwise, i9 Up to 180, in order to minimize the time and length of ;
the rotating movement.
As a part of the safety equipment operations is a startup by electrogenic alternate current generating equipment due to lack of power when a breakdown occurs in -the normal power supply, thus permitting the electrical and electronic equipment to continue in ;~
normal operation under normal operating conditions are -~
resumed.
Operation of the passenger elevator is normal and usual and it i9 not therefore described in this document.
ALT5~NATIVB ~KBODr~ENTS OF T8e INV~NTION
Flgures 12 and 13 represent an alternative embodiment of the radial parking system, in which the parking is similar to that previously described but with the difference that the 2~2:L~3 31 ~ ~;
elevator(10), instead of using cylinders with a single piston, use hydraulic cylinders (55) of the telescopic -~
piston type, thus reducing the length of piston (56) to half if there are two telescopic piston sections, or to one-third in the case of four telescopic piston~. These telescopic cylinders are in common use, for which reason no further details are given here. The rest of the components, both for the building, the elevator, the controls, etc., remain as in the previous description.
Figures 14 and 15 represent another embodiment of the radial parking system in which the latter is similar to those previously described, but with the variation that there is one hydraulic cylinder t57) instead of two, which is placed in the center of the elevator exactly below the platform, and is the same type as the telescopic cylinder with 2, 3 o 4 telescopic pistons. In this case, the piston would have a larger diameter, with a resulting larger pushing area if the same hydraulic pres~ure of the pump is maintained, and the length of the run will be equal to the length of the total height of the floors to which service is to be provided. The action of this piston is directed over the elevator cabin, and the ratio of run is, therefore, 1:1. For the present embodiment, pulleys (20), described in the previous versions, and the cables (34) which were connected to the structural girder (26) underneath the elevator cabin, are eliminated. The stroke 2l~2~3 :~
speed of the piston is, in this case, equal to the speed of movement of the cabin. The use of ~, ';,, ~ 3~

The remainder of all compcnents, both of the building, the elevator, the instruments, etc., will remain unchanged in relation to the main embodiment of this invention.
The embodiment proposed in Figures 16, 17 and 18 i9 characterized by a parking elevator (10) being moved by four cylinders (60) with a single piece tubular piston (not shown), or by telescopic pistons (61, 62), as in the case shown, which can be two, three or four-stage. This alternative embodiment can be used to advantage in installations where the number of floors to be served by the elevator are numerous, and ~he lenght of the cylinder and the pistons must be limited. At the same time, this embodiment reduces the diameter required for each piston by duplicating the number if pistons for the same given weight and the same hydraulic fluid pressure. The elevator system consists of a system similar to that described in the preferred embodiment, where a rotatory tower (11), is - - .:

2 ~ 3 (24), and which has a cabin (25) to lift the car3 through a hydraulic syctem (19) consisting of an oil tank, hydraulic pumps, valves and four cylinders with hydraulic pistons, normal or telescopic type, which are placed vertically at the sides of the cabin, two in vertical ascending form and two in vertical descending form. Each of the pistons has a metallic pulley (63) at the protruding end, where the cables of flexible ~teel in the form of a leaning S are housed, and which at one end are fixed to the base plate (64) of the inverted pistons (62) and, at the other, to the elevator cabin (25), 90 that the movement transmission ratio is 4:1; that is, for each unit of distance travelled by the pistons (61, 62), the cabin tra~els four units of distance. In other words, the distance travelled by the cabin and the speed of ascent and descent is four times greater than that of the pistons.
Another embodiment is shown in Figure~ 19, 20 and 21 in which the parking system is similar to those previously shown but with the elevator featuring two sets of mechanisms consisting of pulleys, cables, counterweights and hydraulic pistons, to obtain vertical movement transmission ratios of 6:1. The system consists of two sets of five grooved pulleys placed on the upper part of rhe elevator tower, at each side of the cabin; three ...-: : - .:
pulleys (66) are fixed at each side and the remaining two ~ ~
' ~
~ ~' 3~ 2~ 12~3 (67) are movable, and move vertically up or down; each of the pulleys having free rotatory movement. The movable pulleys ~67) are linked by a metallic structure or member (68), which keeps them separated and includes at its ends two sliding guides for pulley rails (69), which will keep the movement straight throughout the journey of ascent or descent, which will only be one-sixth of the vertical journey of the elevator cabin (25). The rails are suitably supported and spaced from the secondary structure (11) of the elevator. Two counterweights (70) are hung from the center of the metallic structures (68) of the pulleys, the purpose of which is to reduce the power necessary for raising the elevator cabin plus the weight of the cars and their occupants. The total weight of the two counterweights will in fact be approximately equal to between 120% and 140% of the dead weight of the cabin, plus the elevator load. m e mobile pulleys and the fixed pulleys are connected as shown in figure 19, by means of continuous flexible metal cables (71) in the form of a vertical zigzag with 6 steps, one end of the cables being fixed to the structure of the elevator tower (11) and the other to the elevator cabin. ~3elow the counterweights are two cylinders with oleohydraulic pistons (72), which are supported by the elevator structure (11), and their pistons (73) wor~ vertically underneath the counterweights. mi9 results in the following advantages~
~ .
.~
21 ~2 1~ .~
first, a ratio of cabin travel as compared with the hydraulic piston travel i9 obtained of six to one;
secondly, the counterweights are used to raise the elevator cabin and load, and the hydraulic pistons are only used to lift the counterweights and thus lower the elevator cabin. In fact, the form of operation consists of whether or not the cabin is loaded, oil i9 drained from the hydraulic cylinders, allowing the pistons to retract and lower the counterweights, 90 that the steel cables move one way only and the elevator cabin rises.
When it is wished to lower the cabin, then the hydraulic pump or pumps of the station (19) will inject oil to the cylinders, resulting in the pistons extending beyond the cylinders and pushing the counterweights upwards, thus raising the mobile pulleys, and the cables will move in the opposite direction 90 that the elevator cabin descends.
This embodiment can result in substancial saving in the cost of the elevator mechanisms, since the needs of the oleohydraulic mechanisms is considerably reduced, and also gives us relatively large elevation distances with relatively small pistons.
The embodiment proposed in figures 22, 23 and 24 corre~
sponds to a parking system similar to those previously described but with the difference, as in the previous case, that the car eleva~or has a cable system (71), fixed 21321~3 pulleys (66) and hydraulic cylinders (72), with a transmission ratio of 6:1. In contrast to the previous embodiment, in this case there are no counterweights to raise the elevator cabin (25), and the pi~tons act in the opposite direction, pushing the mobile pulleys downwards to increase the distance separating them from the fixed pulleys. In this case the manner of operation is different from that described in the previous embodiment since, in order to raise the elevator cabin plus the load, hydraulic oil would have to be pumped to the cylinders (72), leading the pistons (73) to project outwards and the mobile pulleys (67) on each side of the elevator to descend, in-creasing the distance between the mobile and fixed pulleys 90 that the cables (71) move to one side, and the elevator cabin (25) rises. On supressing the hydraulic pressure inside the cylinders (72), the pistons contract and the mobile pulleys go up, pulled by the cables, due to the weight of the cabin and load transported. The advantage of this system is a reduction in the overall weight of the e evator, maintaining relatively-small cylinders with very short runs due to the 6:1 ratio.
In either of the foregoing embodiments, the present invention can consists of two or more adjacent parking towers, utilizing the same passenger elevator services and stairs, with the possibility of transferring vehicles from '''"'~''' '' ' .,, -'-39 ~ 2 1 ~ 3 ; ,::

According to the parking system embodiment represented in figures 25, 26 and 27, the car elevator (110) consists of a supporting structure (111), in the form of a hollow paralelepiped, with a 3tructural square containing diagonals and a center plate (112) on the upper face, hanging from the steel cables (113) which hoist the elevator cabin. Four structural legs (114) extend from the vertexes of the square which, in turn, support the lower face of the structure, which i9 similar to the upper face described above, but with the addition of a structural square (115), which sexves to support the rollers (116) the purpose of which i~ described below. An axial load bearing hangs from the central part of the lower face, serving as a pivot for the circular movement of the elevator platform (118).
The metallic sheeting platform (118) is circular and has an axis in the form of a solid shaft in it~ center and .,, :. .
lower parts, and is placed on the lower face of the elevator structure and withi~ the vertical legs forming the edges of the elevator structure. The platform (118) is reinforced in its lower part by two concentric circular channela (119, 119'), one channel (119) being placed within the periphere of the platform and the other channel (119') appproximately in the middle of the platform ~ "'.';

radius, the purpose of these channels being to stiffen the platform and to serve, at the same time, as a taxiway for the turning rollers (116).
The turning rollers (116) will be placed in a minimum of twelve, and consist of rubber coated steel rolllers which contain a solid metallic shaft supported by two side bearings. Each roller group is suitably placed on the lower structure of the elevator (figure 27), and fixed by means os screws and nuts in a suitably angle position.
By the help of the central axial bearing (117) and the loading rollers ~116), the elevator platform can turn 360 by the action of two motors (120), which are vertically placed on the lower part of the platform, suitably fixed to the lower structure of the elevator (110). The two motors have pinion-type gears attached which, on turning, displace a sprocket (121) which is placed on the outside part of the internal reinforcement ring of the platform (118)l anda therefore turn the platform. The motors (120) consist of an electric motor which receives specific signals from the control system in order to adopt a position previously selected by the master control of the logical control programmer. Having two motors, the turning system becomes redundant, thus increasing its reliability to 200%, and allowing a motor to turn the platform in one direction and the other in the other direction, one motor being idle while the other is working.

The hoi~ting motor of the car elevator (122) i placed on the upper part of the parking center, and consists of the conven~ional parts of any passenger elevator, but with a larger capacity. The hoisting mechanism of the elevator consists of a gearmotor, with reversible action, traction pulleys for the cables, counterweights and electrical call, destination, emergency stops, alarm, etc., controls.
In contrast to other conventional elevators, this possesses additional turning controls as described in the preceding paragraph.
As in the foregoing embodiments, the signalling and control system of the parking 3ystem forms a substantive part of same, since it is this which allows semiautomatic and safe operation throughout the system.
Another embodiment of the present invention is shown in figures 28 and 29, consisting of two adjacent towers (A, B) for radial parking, the height and distance between elevators of which is suitably modulated in such a way that the horizontal distance between the elevator centers i8 an lexact multiple of the vertical distance between every two floors, and which has the speciality that the elevator has continuous action in a single direction, having a fixed number of platforms (137), as shown in figure 29. For an arrangement of two towers with 3even levels, there are eight platforms (137) joined by metal chains (138), placed at the ends of a diametral cord. Each ",,",.
21~ 3 of the platforms has its own rotating movement to place the platform at the de~ired angle with respect to the parking spaces for the cars. The plataforms joined by the traction chains (138) ascend by an elevator shaft and subsequently, when they reach the top floor of the parking building, move horizontally over a roller table (139), and then de~cend vertically within the elevator shaft of the ~ ~t adjoining tower, finally moving horizontally in the opposite direction over a second roller table (140) to close the cycle of movement. The chains are moved by racks (141) located in the four vertexes of the elevator's motive system, three of the racks being motorized, with the exception of the lower pulley located where the platforms descend. These racks (141) are impelled by electrical gearmotors of the capacity necessary to carry out the work of lifting the platforms or the movements over the upper and lower roller tables. The work of each motor i9 synchronized with the other two. Conveyance of the electromotive power necessary for the turning motors of the platforms, is carried out by trolleys located on the lateral guides of the elevators and at one end of the roller tables. The control signals to establish the ~ ~
startup, positioning and stoppage of the platform rotative ~ -movement motors is of the shortwave radio type, or an optic sensor with the breadth and lenght of a regulated -wave. The purpose of operating in this embodiment is to .: . .' 43 211~i~i3 :~
have a greater capacity for the entry and exit of cars from the parking system.
The automatization degree is complete, each platform stopping automatically on each floor for a preestablished period of time, allowing drivers to place their cars in the center of elevator platforms through luminous traffic signal~ and audible instructions, following which the platforms descend vertically and turn with a rotatory movement until they find the preselected position and level, to descend radially to the desired parking space.
The exit operation of the cars will be inverse to that of their entry, but with the same control and protection philosophy.
Regarding the embodiment of figures 30 to 34, the car elevator consists of a supporting, rotating and guiding structure formed by a lower metallic table (212), supported by six metallic rollers (213), which turn over a static circular rail (214) anchored to the parking building foundations (201). At its central part, the table (212) has a turning shaft (215), permitting an angular displacement of up to 360, consisting of a shaft which turns within one or several bearings which are rigidly supported in turn by a concrete jackbits which form part of the foundation. Four vertical metallic columns (211) are placed on the swivel table suitably stiffened with secondary structural elements (216) to reduce their .;.

slenderness ratio in the case of relatively high elevators. The four columns (211) serve also as support for fixing the guide rails (217) of the elevator, and the guide rails of the counterweight (235). An engine room is located in the upper part of the four columns (218), containing a traction engine (219) for elevator, together with the pulleys (229) necessary for same. An upper center of turning (221) is installed at the central part of the engine room, which also has a shaft and one or more bearings, fixed to structural girders (222) forming a cross-shaped structure which i9 linked with the internal columns (202) of the building, providing the uppermost center of turning of the elevator.
At the lower part of the turntable (212), two electrical gearmotors (224) are provided, suitably attached to the structure, with connected pinion-type gears (260) which are, in turn, duly geared in a circular ring (223), which is rigidly supported over the reinforced concrete foundations (201) of the parking building. These gearmotors on being placed in operation, will result in the rotation of the elevator (210) as a whole with the Yupporting structure (211), (212), (216), (21~), (219) and (225). The use of two gearmotors has been chosen for the purpose of having a balanced turn at the opposite ends of the ring. The motive elements consist of an electric motor which receives precise signals from the control system, to 2 1 1 2 ~
adopt a position which has been preselected by the master control of the logical control programmer, clockwise or counterclockwise, allowing the turn to take place in the shortest direction between the original cabin position ~ ~ ~
(225) and the final destination position. ;~-The equipment for hoisting the cabin vertically is of traditional elevator type, consisting of a gearmotor (219) ~ `
with a reversible traction pulley, diverting pulleys (220), traction cables (234), cable pulleys (if the traction ratio is 2:1), a counterweight (235) and the necessary fittings to fasten same. ;
Shock absorbers (236) are placed on the upper part of turntable (212), these being spring and oil absorbers, for -the cabin (225) and counterweight (235), for the purpose of progre~sively reducing the impact of a sudden descent ;~
of the elevator cabin.
The counterweight will move vertically up or down in accordance with the relative cabin position, for the purpose of reducing consumption of the power required to lift the cabin and the corresponding load of the car plus it~ occupant~.
With regard to figure~ 35, 36 and 37, these represent a new alternative embodiment of radial car parking, wherein the rotatory elevator is operated by a single hydraulic piston type (251) which will be placed in the lower part of the cabin. This type of elevator is now in common use, .~.
21~2~L63 and their working is not therefore described in detail, mentioning the main parts and the modifications necessary for them to be utilized for this specific purpose.
The revolving structure of the elevator ~211), in addition to the turntable (212), the rollers (213), the circular rail (214), the lower turn shaft (215), the guiding rails (217) and the upper center of turning (221) will remain unchanged. In addition, for this embodiment of the engine room (118), the traction machine (119) and the pulleys (120) are not needed. Instead of the traction equipment, a hydraulic piston (251) fixed to the lower part of the parking lot is included, for which purpose it has a tubular cylindrical casing (250) which will be embedded in the ground and will have the same length as the hydraulic elevator piston (251). The casing (250) will contain the earth and water of the phreatic levels and act as a receptacle for the hydraulic piston (251). The piston is assembled on the turntable (212) and housed within the casing (250), without having contact with the casing because the piston will have a rotatory movement. An important part of the hydraulic piston is its stem, which move~ up to down supporting the weight of the cabin and the weight of the car on applying the hydraulic pressure obtained from the hydraulic pumps (253) which, together with the hydraulic fluid tank (254), are also mounted on the elevator turntable (212).
''-:''''' : ` :
2~ l2163 The gearmotors (224) and circular ring (223) continue to act in a way similar to that described in the cable traction elevator. The control panel will also be similar, but instead of commanding the electrical hoisting motor, will now start the hydraulic pumps in order to increase the pressure or the volume of the hydraulic fluid in the piston, and make the elevator ascend, or reduced these and send the hydraulic fluid coming from the piston to the storage tank, thus forcing the elevator cabin to descend.
Even though the invention has been described in its preferred embodiments, it should be emphasized that other variations can result from the foregoing concepts which wlll be obvious in the light of the foregoing description, which should be taken as an example, with no limitation
