PRACTICAL IMPLEMENTATION OF THE INVENTION

(24) FIGS. 1, 2, 3 and 4 represent some variants of the urban elevator shifter system with portal structure (10) for the crossing of obstacles, which integrates the movement systems of the present invention, which is essentially composed of a portal structure (10) which, in its simplest form, is typically in the shape of U turned upside down and is disposed so as to bypass one or more obstacles, with one or more cabins of transport (20) that move, for the via of the handling systems described hereinafter, in and from along the said portal structure (10), from a station (30) of departure to a station (30) of arrival and vice versa, where said stations (30) departure and arrival are formed at the ends of horizontal runways (11) or vertical runways (12) of the portal structures (10) or in intermediate positions of the vertical runways (12), constituting the intermediate stations (13), of said portal structures (10). Single cabin or more cabins of transport (20) are therefore movable, from a station (30) of departure to a station (30) of arrival and vice versa by means of said movement systems, both in vertical and horizontal.

(25) An elevator shifter system with portal structure (10), of which an example is shown in FIG. 2, with the rack (100, 101) or fixed chain, where the motor is rigidly coupled to the cabin of transport (20) and acts through a pinion gear (500) on the rack (100, 101) or on the fixed chain. In the case of rack (100, 101), to increase the fluidity of the movement with less vibrations and reduce the noise level of the system thus increasing the comfort of the passengers in the cabin of transport (20), is used an angled toothing.

(26) In the case of an elevator shifter system with portal structure (10) with a single cabin of transport (20), to have a single system for moving the cabin that realizes both the vertical and horizontal movement, in order to realize a trajectory curve in corresponding to the passage from a vertical runway (12) to a vertical runway (11) and vice versa, which coupling between sections of vertical rack (101) and horizontal rack (100), is used and curved rack segment (102) in the shape of a circular sector of the pinion. The pinion gear (500) is driven by an electric motor (501) housed in a special compartment of the cabin of transport (20), or placed directly on the sledge (50) which is integral with the cabin of transport (20).

(27) A single motor (501) can be replaced by a pair of motors (501) on the sides of the cabin or on the sledges (50) supporting it, which act separately with an electronic synchronism via encoder and closed loop control and/or as a couple through a shaft of synchronism (502). Such shaft of synchronism (502) can be conveniently placed through the floor (202) of the cabin of transport (20) below the same so as not to constitute alley and obstruction. The use of two electric motors (501) separated can realize a security system in the case where the movement of the cabin of transport (20) can also occur if one of the two motors or its control system is faulty.

(28) The motor (501) or the motors (501) will be equipped with brake Shunt or analogous to that used in the electric winches for elevators, so as to ensure the maintenance in position of the cabin even in case of power failure due to breakdown or for the simple stationary purposes.

(29) To counteract the forces that characterize the mating pinion (400)/rack (101) or the pinion (400)/chain (404), which would tend to turn away between them the two elements, can be prepared a special thrust bearing guide pin (403 and 503) concentric with the axis of the toothed pinion (400 and 500), which acts on a special guide surface thrust bearing (106) suitably shaped to follow and impose the movement of the thrust bearing guide pin (403 and 503) the same.

(30) In the vertical sections, the same rack (101) can be used to ensure the parallel movement of the carriages (40) that move vertically the sledges (50) to which is integral the cabin (20). To achieve this there is provided a synchronous shaft (402) which at each end provides a toothed pinion (400) which engages on the rack (101) in its vertical section. On the same shaft (402) may be provided some brakes which allow to realize a braking system for the only vertical movement of the cabin (20). These brakes can be of electromagnetic type similar to those expected in the motors of winches for elevators.

(31) To increase the transport capacity of an elevator shifter system with portal structure (10) as described in the preceding paragraphs, it is proposed a system of which an example is shown in FIG. 2, with two or more cabins (20) with two-way vertical runway (12) on opposite sides and with two or more horizontal runways (11). This system requires that two or more cabins (20) move on the two vertical sections (12) at the ends of the horizontal sections (11) and on two or more horizontal sections (11) in an autonomous but coordinated way, obtaining for example that, while in a cabin (20) at the end of a vertical runway (12) takes the loading or unloading, another cabin (20) can be in loading or unloading on the opposite side, or it can be in transit, even together with other cabins (20), if the total of the cabins (20) is three or more, along a part of the path constituted by the vertical runway (12) and horizontal runway (11) not engaged.

(32) To obtain the movement of the cabins (20) in the solution in the preceding paragraphs, it is envisaged that the said cabins (20) are equipped with their own motor (501) or of a pair of motors (501) and two sledges (50) with motor (501) as in the previous paragraph. The vertical movement at the two ends of the invention, along its vertical runways (12), is obtained by means of a pair of carriages (40) that realize the continuation of the horizontal runways to the cabin (20) or the sledges (50) that support it. On these carriages (40) and integral to them is fixed an horizontal rack (104), which is a continuation of the rack arranged on the respective horizontal sections of the portal (10) and which allows the system with toothed pinions (500) of the cabin or the related sledges (50) to move horizontally along said carriages (40). Once the pair of carriages (40) is kept aligned with the relative horizontal runway (11), the cabin (20) or the sledges (50) on which it rests there may rise above always through the movement made by the motor (501) or by the motors (501) on the cabin (20) or on its sledges (50).

(33) The vertical movement of the carriages (40) is obtained through a motor (401) or two motors (401) connected between them by a special synchronism shaft (402) or electronically controlled in a synchronous manner, such as for example in the position control in closed loop with encoder. In the case of single motor (401), it will carry out the movement of both carriages through the same shaft of synchronism (402). The pinions (400) at the ends of the shaft of synchronism (402) or motor (401) separately mesh on to suitable racks (105) arranged vertically on the vertical runways (12) also ensures the parallel movement of the carriages themselves.

(34) On each of the two vertical sections (12), as represented by way of example in FIG. 13, may be provided for a pair of carriages (40) only, or two pairs of carriages (41), which move independently of each other. In the case of only one pair of carriages (40), a single cabin (20) at a time can be moved on the same path of the vertical runway (12). The pair of carriages (40), when it has not above a cabin, if not already previously positioned, present themselves in correspondence of the horizontal runway (11) from which comes the cabin (20) to move vertically. Once received the cabin (20) to move, the pair of carriages (40) carries it to the first station (30) in correspondence of the destination or to another of the horizontal runways (12) depending on the case. The cabins (20) can be so moved in a way independent but coordinated between them, exploiting the horizontal runways (11), such alternative paths or parking waiting.

(35) To further increase the transport capacity of the elevator shifter system with portal structure (10) of which an example is shown in FIGS. 1, 3 and 13, may be provided on each of the vertical runways (11) a second pair of carriages (41) with capacity of autonomous movement, which can be parked if necessary in a raised position above the horizontal runway (11) higher. In this way, considering a specific vertical runway, while a pair of carriages (40) is engaged for example in the loading or unloading of a cabin (20), the other pair of carriages (41) can provide to transfer from an horizontal runway (11) to another, another cabin (20).

(36) The cabins (20) can be so moved in a way independent but coordinated between them, exploiting the horizontal runways (11) and part of the way of the vertical runway (12) such alternative runways, as well as the horizontal runways (11) such as cabin parks waiting. With this, it is possible to address particular unbalanced loads of flow of people and things in the two opposite directions, having for example, the possibility of moving of the cabins (20) between an horizontal portion and the other even while other cabins (20) are simultaneously engaged in the loading and unloading stations (30).

(37) To realize a gradual change of direction of the cabin (20) in correspondence of the passage from one way of the horizontal runway (11) to a way of vertical runway (12) and vice versa, the horizontal movement of the cabin (20) or the sledges (50) which is integral with the same, as well as the vertical movement of the carriages (40, 41) on which the cabin (20) or its sledges (50) rise, are adjusted by interpolation so as to make follow a curved and gentle path to the cabin (20), which has the same purpose delegated to the curved rack segment (102) of the preceding paragraphs.

(38) The combination of the movement of the carriages (40, 41) with the movement of the sledges (50), obtained through the position control of the motors (401, 501) by the controller of the system, similarly to what happens in the interpolation of the axes of a machine tool numerical control, allow to realize a trajectory arc in correspondence of the passage between vertical and horizontal, and vice versa of the cabin (20).

(39) In order to overcome a series of obstacles such as for example the tracks in a train station, it is proposed a solution of an elevator shifter system with portal structure (10), an example of which is shown in FIGS. 1 and 3, which provides three or more vertical runways (12) similar to those described in the preceding paragraphs solution and one or more horizontal runways (11), with one or more cabins (20) that move in such a way autonomous but coordinated between all stations (30) placed in the appendices of the portal structure (10) or at intermediate levels (13) along the vertical runways (12). This system includes one or more cabins (20) equipped with its own system of horizontal movement acting on suitable racks (103, 104) arranged horizontally on the horizontal runways (11) and on the carriages (40, 41) that realize the vertical movement of the same cabins (20). Such system provides as in the case of the system to the previous point of the pairs of carriages (40, 41) equipped with an own movement system, with one or more motors (401) which allows the displacement along the vertical runways (12) thus realizing the motion of the cabins (20) that are positioned above.

(40) This system differs from that described in the preceding paragraphs for the fact of providing one or more vertical runways (12) intermediate to the extreme vertical runways. In addition, as shown in FIG. 1, it differs from the system of the preceding paragraphs, including the possibility that there may be all or only a portion of the horizontal runways (11) between the different vertical runways (12), more than one horizontal runways (11). The latter possibility allows to differentiate the movement capacity of the system, with respect to the different stations (30) placed at the ends of the portal structure (10) or on the intermediate floors (13) of the vertical runways (12).

(41) In the case of a system with more than one cabin (20), in order to ensure a greater movement capacity of the system, each of the intermediate vertical sections that intersects one or more horizontal runways (11), needs two pairs of carriages (40 and 41) as described in the preceding paragraphs in such a way that, while a cabin (20) is located for example, in a station (30) for the operations of loading and unloading, engaging a pair of carriages (40), another pair of carriages (41) shall implement the continuity of the way of the horizontal runway (11) so that another cabin (20) transits there above.

(42) Prerequisite for achieving such an elevator shifter system with portal structure (10) with more of a cabin (20) is the ability to move independently between them the cabins (20) optimizing the use of horizontal runways (11) and vertical runways (12). A control system of the electronic type with microprocessor easily realizes the control of the whole system by coordinating and controlling the movement of the cabins (20).

(43) The superposition of two horizontal runways (11) allows to realize an arch able to overcome greater distances through simply going to unite the elements, in the manner of trellis for example, the beams that form the respective horizontal runways (11).

(44) The vertical runways (12) are equipped with at least a pair of said carriages (40 and 41) that realize the continuation of the horizontal runways (11) in correspondence of the relevant vertical runways (12) so that the cabins (20) can come over to be able to realize the vertical movement. Both in ascent and descent of that, such a pair of carriages (40 and 41) will dispose themselves in correspondence of the way of the horizontal runway (11) towards which is bound the cabin (20) or from which comes the cabin (20). When the cabin (20) is on said carriages (40 and 41), through their vertical movement uphill or downhill is also achieved the ascent and descent of the cabin (20). The independent movement of said carriages (40 and 41) is obtained by a special motor (401) or pair of motors (401) integral to the same acting through toothed pinions (400) on special racks (105) arranged vertically along the columns that form the vertical sections (12) of the arch with a portal structure (10). In alternative to the system with the rack, the carriages (40 and 41) can be moved by special chains (404), moved in turn by one or more stationary motors (405), integral to the structure, which act via pinions (406) of said chains (404). In the case of a single motor (405) that realizes the movement of said chains (404), the same are synchronized with each other through a special shaft of synchronism (407) placed for example in the lower part of the vertical runway (12), and in so as not to obstruct the movement of the cabins (20).

(45) In the elevator shifter system with portal structure (10), with more of a cabin (20) described above in its various configurations, for the movement of the cabins (20) along the horizontal sections, as an alternative to the rack (103 and 104) is possible to use wheels coated in non-slip material, which are kept in adherence on the guide rails and which are moved by electric motors (501) similarly to what happens to the pinions (500) which meshes on to the racks.

(46) The said movement system comprises the device of hydraulic balancing of the weight of the cabin (20) in the case of vertical path of adaptive type. In essence, to achieve the purpose described here, is used a device that provides a system of hydraulic spring (601) of variable capacity for each of the carriages (40 and 41) that realize the movement of the cabins (20) along the vertical runways (12). Said device includes a single hydraulic energy storage system (600) (hydropneumatic accumulators) for all systems of hydraulic spring (601), or a number of hydraulic energy storage systems (600) for each of the systems of hydraulic spring (601) (multiple accumulations) preferentially located in proximity of the systems of hydraulic spring (600) themselves. In addition, this device includes a connecting pipe (602) that connects the only hydraulic energy storage system (600) with the different systems of hydraulic spring (601) or different accumulations of hydraulic energy (600) of each of the individual systems of hydraulic spring (601) between them. On this way, the hydraulic fluid (603) consumed or produced by a system of hydraulic spring (601) operated through a system of chain transmission (604) from the relevant carriages (40 and 41) of a vertical portion (12) during its vertical movement and the consequent energy (pressure variation) that it produces or consumes, can be recovered and consumed, respectively, from the same or a different system of hydraulic spring (601) driven by the relative carriage (40) which moves in the opposite direction with the same load. Even in the case of several cabins (20), if all move to and from the same level, apart from the losses due to leakage and the inevitable losses of the hydraulic systems, after that all the loads have been reported on the same floor by which had been taken, it will be obtained that the energy or hydraulic pressure of the hydraulic energy storage system of single (601) or hydraulic energy storage systems of the individual systems of hydraulic spring (600) is restored to the initial value thereby accomplishing energy recovery. Hydraulic springs (601) are of variable capacity, governed by an electronic system that, based on the weight of the load which insists on the cabin (20), detected through special load cells, determine the power of the hydraulic springs (601) themselves.

(47) The same function of hydraulic spring (601) variable capacity obtained through a set of hydraulic cylinders (605) with different surfaces of thrust or power, suitably chosen to achieve a scale of powers that act in such a way as to balance the system in an appropriate weight of the cabin (20) in a system of vertical and horizontal movement, can be obtained from a set of pumps/hydraulic motors (606) with different displacements acting on a toothed pinion (400) meshing with a rack (105) or to a fixed chain. This set of pump/motor hydraulic will transform, similar to the hydraulic cylinders (605), the energy possessed by the hydraulic fluid (603) or pressure, in moving mechanical linear system through said pinion (400)/rack (101) or the one sprocket/fixed chain. The set of pumps/hydraulic motors described here can advantageously act on the same shaft of synchronism (402) that connects a pair of carriages (40 and 41), both in the case that they are provided with their own electric motor (401) that in one in which they are lacking of. The set of pumps/hydraulic motors described here can advantageously be replaced by a pump/motor of variable hydraulic displacement which allows to modify the power according to the load of the cabin (20).

(48) The balancing adaptive system referred already described in D4 and the one here provided in the preceding paragraphs that is the evolution of the same, can be used even in these systems even in the case of transfer of loads to be transported from the cabins (20) from and to different floors between them, provided that in such systems be provided the maintaining of the pressure in the hydraulic energy storage system (600) (hydropneumatic accumulators) within defined values using an hydraulic pump (607) moved from its motor (608) and a control valve pressure (609). Through these elements, a prevailing pressure loss (consumption of hydraulic energy), for example caused by the displacement of the prevailing loads from the lower floors to the upper floors, or by the acquisition of energy (pressure increase), caused for example by the shift of the prevailing loads from upper floors to lower floors, respectively, will be compensated by the energy supplied by the hydraulic pump (607) and that consumed by the pressure regulating valve (608), respectively. The hydraulic pump (607) withdraws in fact the hydraulic fluid (603) from the reservoir (610) and compresses the interior of the accumulator (600), while the valve adjustment pressure, transfers the hydraulic fluid (603) in excess in the accumulators (600), in the tank (610). The hydraulic system of balancing will act ultimately in the same way as an elevator system with hydraulic control contributing to the lifting of loads that must be moved from a lower plane to a higher plane. The energy required for lifting a load which is subsequently recovered from dropping the same load, will be supplied by the motor (608) that drives the pump (607).

(49) An advantage in terms of energy can result in the proposed solution, by preparing accumulations (600) (hydropneumatic accumulators) more capacious and/or an hydraulic motor (611) powered by the fluid in output from the pressure regulating valve (609) here provided, which in turn moves an electric current generator (612). The electricity produced by the generator (612) can be fed back into the mains of withdrawing or consumed by other parts of the system or its accessories.

(50) An effective system of protection of the organs that perform the horizontal movement of the cabin (20) is given by a cover (107) that completely covers from the side such organs along the horizontal runways (11). Below this cover (107), may be protected all the mechanical and electrical connection of all systems. In this way, the cabin (20) can be supported and connected to the sledges (50) or to the part of the same cabin (20) which acts as a sledge, through the shelves (503) which keep it raised from under the floor. The opening of shelves passage (108) through which pass these shelves (503) will be as small as possible and may in turn be protected by brushes or flexible membranes. The position of this opening of shelves passage (108) and its size are such as to prevent external elements such as water, snow, dust, etc. from entering the premises in which they find space the movement devices.

(51) Exploiting the particular suspension system of the cabin (20) from below the bottom or floor (202), realized by means of the shelves (503) described previously, it is possible to obtain on the side walls of the cabin (20) some openings (200), which will normally be closed by a door (201), through which it can be accessed directly from the cabin (20) to the covers (107), and once removed the latter, to the sledges (50) and possibly also to the carriages (40 and 41). Through the openings (200) of the cabin (20), will therefore be possible to perform control operations and maintenance on the organs of horizontal movement of the cabin (20).

(52) An effective system for optimizing the movement and coordination of the elevation and shifting of the cabins (20) in an elevator shifter system with portal structure (10) with more than one cabin (20), is achieved by applying an artificial vision system in the vicinity of stations (30) or access to the areas through which users converge toward the stations (30). Through the interpretation of the data collected from such a vision system, the artificial intelligence system can: Calculate the number of users who are getting ready to climb Calculate the time of entry into the cabin (20) Develop help message or warning that influence the behavior of users. Recognize the type of users, based on the speed of movement, to the stature, to the objects transported, means of aid used, apparent age, to a particular state (pregnancy, pathology, etc.), etc.
Based on all this, the artificial intelligence system can: Ensure the handling of the cabins (20) in order to bring them closer to the stations (30) where there is greater need. Provide a pre-calculation of the route and the speed of movement of the cabins (20) without waiting for the command of the user. Optimize the paths of the cabins (20). Support, through visual signals and/or noise, the users, with a particular focus, for example, on those with mobility difficulties, etc. Through a system of acquisition of sounds, the artificial intelligence system can further characterize the users, for example, recognizing the language and adapt accordingly its visual and audio signals. The artificial intelligence system may be prepared for self-learning in order to further optimize the efficiency of the plant. The process of self-learning can be made so: Development of sound and image data continue relating to a specific station (30) said in progress, with update of an array of data called needs to be processed, until the occurrence of a key event which, for example, the manual start call of the cabin (20) from the station in process. Freezing and storage of the data matrix of needs to be processed in a special database called experience. Development of needs to be processed according to the logic wired of the system with the production of a work order processed, with calculation of a predicted reports of predicted work. Recovery from the database experience of a small number of needs already processed previously called nearby needs among the closest (relative closeness of the values of the matrix) to the needs to be processed. Contemporary retrieval from the database experience of work orders applied to nearby needs. Contemporary retrieval from the database experience of reports of work related to work orders applied to nearby needs. Execution of the work order chosen as the best among work order calculated and close work orders based on the relative data of the report of predicted work and work reports of nearby work orders. Memorizing work order chosen in the previous step as a work order in processing At the completion of the last phase of the work work order in processing, storing the same as order of historical work and storing the related report of work. Cyclical repetition of all the steps described above for each of the stations (30) of the system. Through the extension of the data processed by the system of artificial intelligence and an appropriate weighting of the parameters that influence the choices of self-learning system described above, the elevator shifter movement system will implement more efficient work cycles.
