Definitions
- the present invention refers to a mobile plant comprising a unit movable between predefined stoppage positions, in particular a vertically or horizontally moveable unit.

- a typical example of such transportation devices are underground railways, underground or long-distance trains and so on.
- the stops of the devices take place at a landing platform, in one case consisting of the stopping floor of the lift and in the other case consisting of the unloading platform of the station.
- Solutions of this kind make it possible to visually highlight the sill itself and in particular the presence of the difference in level, in such a way trying to draw the user's attention to the presence of the gap between the cabin door sill and the floor sill in order to prevent objects from falling into the lift shaft or possible accidents due to the possible step that is formed.
- the purpose of the present invention is to avoid the aforementioned drawbacks.
- a further purpose of the present invention is to make a mobile plant using a sill signalling unit of a unit moveable between predefined stoppage positions that is simple, cost-effective and particularly functional.
- a mobile plant using a sill signalling unit 10 of a unit 20,20' moveable between predefined stoppage positions is shown, wholly indicated with 100.
- a unit that is moveable vertically 20 or horizontally 20' between predefined stoppage positions comprises at least one transport cabin 21 equipped with at least one opening 25 selectively closable through a respective cabin door 22, each provided with at least one wing 22a,22b moveable between an open position and a closed position.
- the at least one opening 25 of the transport cabin 21 lowerly defines, at the floor of the cabin 21, a cabin door sill 23.
- Such mobile units 20,20' also comprise a sill bulkhead 24, i.e. a skirt surface that, from a cabin door sill 23 of the mobile unit 20,20', projects at the bottom to close the slit that, in the case of vertical misalignment between the cabin door sill 23 and a corresponding landing platform 30, would be created between the mobile unit 20,20' and such a platform 30, possibly also shielding the components of the mobile unit 20,20' beneath the cabin 21.
- a sill bulkhead 24 i.e. a skirt surface that, from a cabin door sill 23 of the mobile unit 20,20', projects at the bottom to close the slit that, in the case of vertical misalignment between the cabin door sill 23 and a corresponding landing platform 30, would be created between the mobile unit 20,20' and such a platform 30, possibly also shielding the components of the mobile unit 20,20' beneath the cabin 21.
- the unit 20,20' is moveable inside a sliding compartment 31 that, in the case of vertically moveable units 20 consists of a closed shaft extending vertically provided, at each floor, with a shaft opening, generally closable through a respective shaft door 32.
- each floor constitutes a landing platform 30.
- sliding compartment 31 identifies the space defined on one side by an unloading platform 30, extending parallel and in general at a lower level with respect to it 30, on the bottom of which, in the case of rail transportation devices, the sliding tracks of the mobile unit 20' are housed.
- the sill signalling unit 10 comprises at least one sill marker 11 having characteristics such as to be able to be applied onto the sill bulkhead 24 of a mobile unit 20,20' without hindering its movement.
- the at least one sill marker 11 comprises at least one light source 11.
- a light source 11 that is particularly suitable for the purpose consists of a strip LED, i.e. circuits made in a strip, comprising at least one LED and integrating the connections to it, where the at least one LED faces a first side of the strip and on the opposite side a layer of adhesive material is provided for the application of the strip circuit onto a surface.
- Such a type of light source 11 is able to provide sufficient lighting power to ensure good visual indication whilst occupying particularly small bulks that simplify its positioning even in restricted environments.
- the at least one sill marker 11 is connected to electronic processing means 14 suitable for driving the switching on and off of the at least one sill marker 11 in relation to an activation signal 13 corresponding to the stopping of the mobile unit 20,20' at a landing platform 30 that determines an opening signal of the at least one cabin door 22 and/or of the corresponding shaft door 32.
- the electronic processing means 14 are preferably connected to a cabin door 22 opening sensor 16, for example of the magnetic type, where the opening signal of the cabin door 22 generated by the opening sensor 16 is used as activation signal 13 received as input to the electronic processing means 14.
- the electronic processing means 14 are connected to the electronic piloting means (not illustrated) of the transport cabin 21 in order to take the opening signal of the at least one cabin door 22 generally generated when the cabin 21 is present at a landing platform 30.
- the electronic processing means 14 are connected to an electromechanical device (not illustrated) to command the opening of the shaft door 32, like for example an electric shoe, which provides a power off signal to indicate that the mobile cabin 21 is at the floor.
- the sill signalling unit 10 also preferably comprises at least one level difference sensor 12 for determining a vertical misalignment between the cabin door sill 23 and the landing platform 30.
- Such a level difference sensor 12 is preferably of the magnetic type, being made up of a first magnetic element 12a able to be constrained to the mobile unit 20,20', for example in association with each cabin door sill 23, and at least one second magnetic element 12b able to be associated with the at least one landing platform 30.
- the second magnetic element 12b is made in the form of a continuous magnetic strip or a plurality of magnetic strips applied at the vertical wall with which the unloading platform 30 defines the sliding compartment 31 of the mobile unit 20', to substantially cover the entire development of such a platform 30 parallel to the direction of movement of the unit 20'.
- the first magnetic element 12a is installed on the transport cabin 21, above the cabin door 22.
- the second magnetic elements 12b are constrained one for the shaft opening, above it, as well as facing inside the sliding compartment 31 of the vertically mobile unit 20.
- first and the second magnetic element 12a,12b are installed, respectively, below the cabin door 22 and below the compartment openings.
- the installation of the second magnetic element 12b takes place at the position in which ideally, in order to have perfect vertical alignment, the first magnetic element 12a constrained to the transport cabin 21 would be positioned.
- a substantial alignment of the two magnetic elements 12a,12b of the magnetic sensor 12 therefore determines that the mobile unit 20,20' has stopped in the absence of vertical misalignment between the cabin door sill 23 and the landing platform 30.
- a vertical misalignment of the two magnetic elements 12a,12b of the magnetic sensor 12 determines a difference in level between the cabin door sill 23 and the landing platform 30, thus generating a corresponding signal.
- the level difference sensor 12 is of the photo-cell type.
- the sill signalling unit 10 also comprises at least one level difference marker 11,15, preferably coinciding with the sill marker 11.
- the at least one level difference marker 11,15 comprises an acoustic signalling means 15.
- the level difference sensor 12 and the at least one level difference marker 11,15 are connected to the electronic processing means 14 suitable for driving the switching on and off of the at least one level difference marker 11,15 as a function of the activation signal generated by the level difference sensor 12 in the case in which a vertical misalignment between the cabin door sill 23 and the landing platform 30 is actually detected.
- Both the light source 11, and the at least one acoustic signalling means 15 can be activated continuously or intermittently.
- the light source 11 is optionally of the type that can be activated in many distinct colours, in order to distinguish the sill marker from the level difference marker.
- the operation of the sill signalling unit 10 of a mobile unit between predefined stoppage positions is as follows.
- the cabin door 22 opening sensor 16 the electronic piloting means of the transport cabin 21 or the electromechanical device for commanding the opening of the shaft door 32 generate an opening signal of the at least one cabin door 22 or a release signal of the relative shaft door 32.
- Such an opening or release signal acts as an activation signal 13 received as input to the electronic processing means 14, which therefore proceed to activate the sill marker 11.
- the sill signalling unit 10 is therefore able to highlight the position of the cabin door sill 23 of the mobile unit 20,20' drawing the attention of passengers in relation to the potentially hazardous position taken up by it 23 through a light signal.
- the activation signal 13 received by the electronic processing means 14 also acts as activation of the level difference sensor 12.
- the first magnetic element 12a constrained to the mobile unit 20,20' detects the presence of the second magnetic element 12b associated with the landing platform 30.
- an activation signal of the at least one sill marker 11,15 is generated, where, preferably, in relation to the at least one light source 11 the activation signal after it has been determined that there is a level difference is distinguishable from the activation signal due to the presence of the mobile unit 20,20' at the landing platform 30, for example in terms of continuous or intermittent activation or in terms of colour.
- the level difference marker 11,15 advantageously positioned on the sill bulkhead 24, is easily applicable even to pre-existing transportation cabins 21 still providing a valid light and/or acoustic signal of the potential danger consisting of a vertical misalignment between the cabin door sill 23 and the landing platform 30.
- the level difference sensor 12 generates an activation signal of the light source 11 and/or of the acoustic signalling means 15 also in the case in which there is a gap between the landing platform 30 and the cabin door sill 23 of a size such as not to allow the first magnetic element 12a to detect the presence of the second magnetic element 12b, even in the presence of vertical alignment between them 23,30.
- the sill signalling unit 10 is therefore also able to signal the presence of such a gap, warning passengers of the relative situation of potential danger through a light and/or acoustic signal.
- the sill signalling unit can also be easily installed on pre-existing mobile plants thanks to the particular architecture adopted, whilst still offering high reliability of signalling of a potential hazard at the sill, for example deriving from a vertical misalignment of the door sill of the cabin and of the landing platform or from an excessive gap between them.

Description
- The present invention refers to a mobile plant comprising a unit movable between predefined stoppage positions, in particular a vertically or horizontally moveable unit.
- By unit that is vertically moveable between predefined stoppage positions we mean any kind of lifting device such as a lift for transporting people or things vertically or a freight elevator for transporting materials vertically, both configured to make stops at predetermined heights, in general at a specific floor.
- By mobile unit that is horizontally moveable between predefined stoppage positions we mean all transportation devices by rail or guideways that foresee stops within well-defined spaces, like at an unloading platform in a stopping station. A typical example of such transportation devices are underground railways, underground or long-distance trains and so on.
- Both in lifting devices and in rail or guideway transportation devices the stops of the devices take place at a landing platform, in one case consisting of the stopping floor of the lift and in the other case consisting of the unloading platform of the station.
- The stopping of such mobile units does not always take place in perfect vertical alignment with the corresponding landing platform, sometimes creating a difference in level such as to be able to cause accidents in the passing of people and goods, as well as having objects fall in the gap that is formed between the mobile unit and the platform.
- In the field of lifts it is known to insert a light signal into the sill profile of the floor door and/or into the sill profile of the cabin door, which is activated whenever there is a displacement between the stopping height of the cabin and the floor. Examples of such a solution are described in documents
WO 2006/045211 ,DE 10 2007 049548JPH07228459 - Solutions of this kind make it possible to visually highlight the sill itself and in particular the presence of the difference in level, in such a way trying to draw the user's attention to the presence of the gap between the cabin door sill and the floor sill in order to prevent objects from falling into the lift shaft or possible accidents due to the possible step that is formed.
- The insertion of lights signals in the sill profiles of the cabin and/or floor doors requires major interventions on the plant, such as, in some cases, the replacement of parts of the mobile unit, actually making it not very convenient to install the light signal on pre-existing plants.
- The purpose of the present invention is to avoid the aforementioned drawbacks.
- A further purpose of the present invention is to make a mobile plant using a sill signalling unit of a unit moveable between predefined stoppage positions that is simple, cost-effective and particularly functional.
- These and other purposes according to the present invention are accomplished by making a mobile plant as outlined in claim 1.
- Further characteristics of the mobile plant comprising a unit moveable between predefined stoppage positions are the object of the dependent claims.

sill signalling unit 10 of aunit 20,20' moveable between predefined stoppage positions is shown, wholly indicated with 100. - In general, a unit that is moveable vertically 20 or horizontally 20' between predefined stoppage positions comprises at least one
transport cabin 21 equipped with at least one opening 25 selectively closable through arespective cabin door 22, each provided with at least onewing - The at least one opening 25 of the
transport cabin 21 lowerly defines, at the floor of thecabin 21, acabin door sill 23. - Such
mobile units 20,20' also comprise asill bulkhead 24, i.e. a skirt surface that, from acabin door sill 23 of themobile unit 20,20', projects at the bottom to close the slit that, in the case of vertical misalignment between thecabin door sill 23 and acorresponding landing platform 30, would be created between themobile unit 20,20' and such aplatform 30, possibly also shielding the components of themobile unit 20,20' beneath thecabin 21. - In general, the
unit 20,20' is moveable inside asliding compartment 31 that, in the case of verticallymoveable units 20 consists of a closed shaft extending vertically provided, at each floor, with a shaft opening, generally closable through arespective shaft door 32. In this case, each floor constitutes alanding platform 30. - In the case of horizontally moveable units 20', the term
sliding compartment 31 identifies the space defined on one side by anunloading platform 30, extending parallel and in general at a lower level with respect to it 30, on the bottom of which, in the case of rail transportation devices, the sliding tracks of the mobile unit 20' are housed. - The
sill signalling unit 10 comprises at least onesill marker 11 having characteristics such as to be able to be applied onto thesill bulkhead 24 of amobile unit 20,20' without hindering its movement. - Preferably, the at least one
sill marker 11 comprises at least onelight source 11. - A
light source 11 that is particularly suitable for the purpose consists of a strip LED, i.e. circuits made in a strip, comprising at least one LED and integrating the connections to it, where the at least one LED faces a first side of the strip and on the opposite side a layer of adhesive material is provided for the application of the strip circuit onto a surface. - Such a type of
light source 11 is able to provide sufficient lighting power to ensure good visual indication whilst occupying particularly small bulks that simplify its positioning even in restricted environments. - The at least one
sill marker 11 is connected to electronic processing means 14 suitable for driving the switching on and off of the at least onesill marker 11 in relation to anactivation signal 13 corresponding to the stopping of themobile unit 20,20' at alanding platform 30 that determines an opening signal of the at least onecabin door 22 and/or of thecorresponding shaft door 32. - For this purpose, the electronic processing means 14 are preferably connected to a
cabin door 22opening sensor 16, for example of the magnetic type, where the opening signal of thecabin door 22 generated by theopening sensor 16 is used asactivation signal 13 received as input to the electronic processing means 14. - Alternatively, the electronic processing means 14 are connected to the electronic piloting means (not illustrated) of the
transport cabin 21 in order to take the opening signal of the at least onecabin door 22 generally generated when thecabin 21 is present at alanding platform 30. - In the case of a vertically
mobile unit 20 with manually-openedcabin doors 22, the electronic processing means 14 are connected to an electromechanical device (not illustrated) to command the opening of theshaft door 32, like for example an electric shoe, which provides a power off signal to indicate that themobile cabin 21 is at the floor. - The
sill signalling unit 10 also preferably comprises at least onelevel difference sensor 12 for determining a vertical misalignment between thecabin door sill 23 and thelanding platform 30. - Such a
level difference sensor 12 is preferably of the magnetic type, being made up of a firstmagnetic element 12a able to be constrained to themobile unit 20,20', for example in association with eachcabin door sill 23, and at least one secondmagnetic element 12b able to be associated with the at least onelanding platform 30. - According to an embodiment specifically suitable for horizontally moveable units 20', the second
magnetic element 12b is made in the form of a continuous magnetic strip or a plurality of magnetic strips applied at the vertical wall with which theunloading platform 30 defines thesliding compartment 31 of the mobile unit 20', to substantially cover the entire development of such aplatform 30 parallel to the direction of movement of the unit 20'. - According to an alternative embodiment, specifically suitable for vertically
moveable units 20, the firstmagnetic element 12a is installed on thetransport cabin 21, above thecabin door 22. The secondmagnetic elements 12b, on the other hand, are constrained one for the shaft opening, above it, as well as facing inside thesliding compartment 31 of the verticallymobile unit 20. - In a totally equivalent manner, the first and the second
magnetic element cabin door 22 and below the compartment openings. - In particular, the installation of the second
magnetic element 12b takes place at the position in which ideally, in order to have perfect vertical alignment, the firstmagnetic element 12a constrained to thetransport cabin 21 would be positioned. - A substantial alignment of the two
magnetic elements magnetic sensor 12 therefore determines that themobile unit 20,20' has stopped in the absence of vertical misalignment between thecabin door sill 23 and thelanding platform 30. - On the other hand, a vertical misalignment of the two
magnetic elements magnetic sensor 12 determines a difference in level between thecabin door sill 23 and thelanding platform 30, thus generating a corresponding signal. - In alternative embodiments, the
level difference sensor 12 is of the photo-cell type. - The
sill signalling unit 10 also comprises at least onelevel difference marker sill marker 11. - According to a preferred embodiment, in addition or as an alternative to the
sill marker 11, the at least onelevel difference marker - The
level difference sensor 12 and the at least onelevel difference marker level difference marker level difference sensor 12 in the case in which a vertical misalignment between thecabin door sill 23 and thelanding platform 30 is actually detected. - Both the
light source 11, and the at least one acoustic signalling means 15 can be activated continuously or intermittently. Moreover, thelight source 11 is optionally of the type that can be activated in many distinct colours, in order to distinguish the sill marker from the level difference marker. - The operation of the
sill signalling unit 10 of a mobile unit between predefined stoppage positions is as follows. - Once the
mobile unit 20,20' reaches alanding platform 30, thecabin door 22opening sensor 16, the electronic piloting means of thetransport cabin 21 or the electromechanical device for commanding the opening of theshaft door 32 generate an opening signal of the at least onecabin door 22 or a release signal of therelative shaft door 32. - Such an opening or release signal acts as an
activation signal 13 received as input to the electronic processing means 14, which therefore proceed to activate thesill marker 11. - The
sill signalling unit 10 is therefore able to highlight the position of thecabin door sill 23 of themobile unit 20,20' drawing the attention of passengers in relation to the potentially hazardous position taken up by it 23 through a light signal. - In embodiments also comprising the
level difference sensor 12, theactivation signal 13 received by the electronic processing means 14 also acts as activation of thelevel difference sensor 12. - In the case of a
level difference sensor 12 of the magnetic type, the firstmagnetic element 12a constrained to themobile unit 20,20' detects the presence of the secondmagnetic element 12b associated with thelanding platform 30. - In the case in which the two
magnetic elements sill marker - Differently, in the case of vertical misalignment between the two
magnetic elements sill marker light source 11 the activation signal after it has been determined that there is a level difference is distinguishable from the activation signal due to the presence of themobile unit 20,20' at thelanding platform 30, for example in terms of continuous or intermittent activation or in terms of colour. - The
level difference marker sill bulkhead 24, is easily applicable even to pre-existingtransportation cabins 21 still providing a valid light and/or acoustic signal of the potential danger consisting of a vertical misalignment between thecabin door sill 23 and thelanding platform 30. - Advantageously, in the case of horizontally mobile units 20', the
level difference sensor 12 generates an activation signal of thelight source 11 and/or of the acoustic signalling means 15 also in the case in which there is a gap between thelanding platform 30 and thecabin door sill 23 of a size such as not to allow the firstmagnetic element 12a to detect the presence of the secondmagnetic element 12b, even in the presence of vertical alignment between them 23,30. - The
sill signalling unit 10 is therefore also able to signal the presence of such a gap, warning passengers of the relative situation of potential danger through a light and/or acoustic signal. - From the description that has been made, the characteristics of the mobile plant and of the sill signalling unit of a unit moveable between predefined stoppage positions are clear, just as the relative advantages are also clear.
- The sill signalling unit can also be easily installed on pre-existing mobile plants thanks to the particular architecture adopted, whilst still offering high reliability of signalling of a potential hazard at the sill, for example deriving from a vertical misalignment of the door sill of the cabin and of the landing platform or from an excessive gap between them.
- Finally, it is clear that the mobile plant and the sill signalling unit of a unit moveable between predefined stoppage positions thus conceived can undergo numerous modifications and variants, all of which are covered by the invention; moreover, all of the details can be replaced by technically equivalent elements. In practice, the materials used, as well as the sizes, can be whatever according to the technical requirements.
