Definitions

  • the invention relates to a method of controlling operation of a lift system comprising a stair lift or a platform lift, as well as a corresponding lift system with a stair lift or a platform lift.
  • a stair lift can be used to transport a handicapped person between a first elevation and a second elevation, e.g. up and down a staircase by means of transport device such as a chair.
  • stair lifts comprise a guide rail extending along a stair case periphery and a motorised carriage with a chair, arranged to drive the carriage and chair along the rail.
  • Platform lifts can be used to raise a handicapped person, e.g. in a wheelchair, to a higher elevation, or to transport a handicapped person between floors in a building. Such platform lifts can also be used to transport loads.
  • Such lift systems comprising stair lifts or platform lifts can be installed in buildings in order to provide access to the building for handicapped persons.
  • stair lifts and platform lifts can for example be leased or rented from a manufacturer. It is of utmost importance that such lift systems are regularly serviced in order to ensure safe and reliable operation at all times.
  • many institutions using such lift systems do not pay sufficient attention to regular servicing, thereby taking risks regarding comfort and safety of for example handicapped users.
  • Such usage of a lift system after the lapse of a servicing interval without adequate servicing can be considered hazardous or unauthorised operation of a lift system.
  • the invention comprises a locking device for preventing unauthorised operation of the lift system. If a predetermined condition is not met within a predetermined operating interval of the lift system, the locking device is adapted to prevent further operation of the lift system, i. e. to deactivate the lift system, after a predetermined operating interval or another predetermined interval. Examples of such predetermined conditions to be met comprise for example the observation of service intervals, i.e. effecting a servicing of the lift system within a specified service interval, usage of the lift system by authorised users only, and payment of lease fees within predetermined time intervals.
  • the terms "operating interval” and "interval” as used in the present context can either refer to a time interval, or a measure of usage, for example a specified number of movements of the lift system between a first elevation and a second elevation.
  • the locking device expediently comprises a controller such as a CPU or a computer, which can be controlled by input of command signals, and which is adapted to generate signals to enable deactivation and/or activation of the lift system. For example, when a predetermined condition has been met, a password or code can be automatically transmitted to a controller of the locking device via an internet or another remote connection. Also it is possible to provide a user of the actual lift with a password or code, which can then be entered manually.
  • the lift system according to the invention is especially adapted to enable handicapped persons of limited mobility, especially persons confined to wheelchairs, to be able to move between different elevations.
  • the platform lift can be provided in a vertically moving or a transversely moving manner.
  • the lift according to the invention can also be provided as a chair lift or an escalator.
  • the predetermined condition is a servicing of the lift system within a predetermined operating interval. Only if it is confirmed that a servicing of the lift system has been performed within such an interval, will operation of the elevator system be maintained. If this predetermined condition is not met within such an interval, the lift is deactivated.
  • a further example of such a condition to be met is fulfilment of a financial obligation, such as a rent or lease payment, within a predetermined time interval.
  • the locking device of the elevator system comprises a receiver adapted to receive signals from a remotely provided transmitter, confirming that the predetermined condition has been met.
  • a receiver adapted to receive signals from a remotely provided transmitter, confirming that the predetermined condition has been met.
  • a corresponding signal which can be a code or a password
  • the term "remote” in this connection can mean a few metres or any number of kilometres away from the lift system.
  • the predetermined signal is transmitted to the receiver by a remotely provided transmitting device. It is, however, also possible to directly enter such a signal, for example a code or a password, manually into the locking device.
  • Remote transmission can include short distance wireless transmission, such as Bluetooth or long distance wireless transmission or internet transmission.
  • operation of the lift system is prevented by deactivating the lift system when the transport device, for example the platform of a platform lift or the chair of a stair lift, is in the first elevation or the second elevation.
  • the transport device for example the platform of a platform lift or the chair of a stair lift
  • the lift system is not deactivated whilst the transport device is in an intermediate position between the first elevation and the second elevation. This measure ensures that for example a handicapped person will not be trapped between elevations.
  • a warning signal is generated when or shortly before the predetermined operating time has lapsed without the predetermined condition having been met.
  • a grace interval can be chosen to be, for example, 1 hour or 1 day.
  • a grace interval is an example of "another predetermined interval" as mentioned in claim 1.
  • the locking device is especially adapted to directly influence mechanical and/or electrical components of the lift system.
  • the locking device can disable certain mechanical and/or electrical components of the lift system.
  • the locking device can especially disable all of the mechanical and/or electrical components of the lift system.
  • the locking device can determine whether the predetermined condition is met for another operating interval. Thus, it can regularly be checked whether the predetermined condition is met and whether the lift system is operated with correct authorisation. For example, if a servicing is performed too late or a lease fee is paid after lapse of an agreed interval, the lift system can easily be taken back into operation.
  • the predetermined operating time of the lift system can be chosen in order to give the user a reasonable amount of time to meet the predetermined condition, e.g. to effect servicing.
  • the predetermined operating time can also be a demo time, during which the lift system can be tested by a user. After corresponding activation within the demo time, the lift system can further be operated throughout a predetermined interval.
  • the predetermined operating interval can especially be chosen between 30 days and 180 days.
  • the locking device comprises a receiver.
  • the predetermined condition can also be defined as reception of a predetermined unlocking signal by said receiver. Receiving said signal indicates that the certain condition is met.
  • the receiver can for example be a radio receiver.
  • An unlock signal transmitting device can be provided to transmit the unlock signal.
  • a transmitting device can, for example, be a radio transmitter. It can also be adapted to send a signal via the internet. Also, it is possible to provide the transmitting device with a comparatively short range of transmission, for example 2 to 3 meters. In this latter case, the transmitting device can be used in the direct vicinity of an elevator system.
  • the locking device is adapted to prevent further operation of the lift system, when the stair lift or the platform lift is in a lower elevation, e.g. a ground level, if the predetermined operating time is elapsed and the predetermined condition is not met.
  • a lower elevation e.g. a ground level
  • users of the lift system are trapped when the predetermined operating interval expires while a transport process between two elevations is in progress.
  • the stair lift or the platform lift thus must return to the ground level, before further operation of the lift system is prevented.
  • all users can safely dismount the lift system in the ground level.
  • FIG. 1 schematically shows a lift system 100.
  • the lift system shown depicts an "inclined” platform lift, i.e. which moves along an inclined trajectory such as a flight of stairs or a staircase.
  • the invention is equally applicable e.g. to "vertical" platform lifts (i.e. performing a vertical movement) or corresponding inclined or vertical chair lifts.
  • the lift system 100 comprises a platform lift 110 with a transport means 111 in the embodiment shown a platform 111.
  • the platform lift 110 is installed on a staircase 120.
  • a person e.g. confined to a wheelchair (not shown in figure 1 ) can be enabled to move between a ground floor (first elevation) and a first floor (second elevation).
  • the platform 111 of platform lift 110 is powered by an electric drive 113, so that it can be moved between the ground floor 121 and the first floor 122.
  • a person confined to a wheelchair can access platform 111 of the platform lift 110 via a ramp 112. After the person has accessed platform 111, the ramp can be moved into a secure position 112a, for example to prevent the wheelchair rolling off.
  • a locking device 130 which, upon activation can prevent operation of the lift system. Preferred embodiments of such an activation (and corresponding de-activation of the lift system) will now be described with reference to the method according to the invention.
  • FIG. 2 A preferred embodiment of a method according to the invention is schematically shown in figure 2 in form of a block diagram and will be explained referring to figure 1 and figure 2 .
  • a manufacturer installs platform lift 110 on staircase 120 and ensures normal operation.
  • a predetermined operating interval of lift system 100 for example 180 days or 1 year is set.
  • the operating interval can be set according to specific conditions, for example expected amount of usage and thus resulting wear over a specified time interval or taking into account a time period for which a user has paid a rental fee (step 202).
  • step 203 which can either be performed regularly or when the operating interval has lapsed, locking device 130 ascertains whether the predetermined condition has been met within the predetermined operating interval.
  • step 202 the method reverts to step 202 and sets a new operating interval.
  • This setting of a new operating interval can be achieved remotely, by communication of the locking device 130 with a remotely provided transmitter.
  • This transmitter is adapted to send a corresponding signal (unlock signal) to receiver 131.
  • the resetting of the interval time can be performed automatically.
  • a corresponding signal is generated by locking device 130 and transmitted to a remote control device.
  • This control device can generate a corresponding message, for example for a servicing company or a manufacturer, to send the user a (physical) unlock transmitting device 140.
  • the user can, for example, push a button 141 of this unlock transmitting device, so that the unlock transmitting device sends an unlock signal to locking device 130.
  • the transmission range of transmitting device 140 will typically be 1 to 2 meters.
  • step 203 If receiver 131 has not received the unlock signal within the predetermined operating time, it is ascertained in step 203 that the predetermined condition has not been met. If this is ascertained in step 203, it is checked in step 204 whether the transport device, i.e. platform 111 is currently being moved between ground floor 121 and first floor 122. If this is not the case, locking device 130 can be adapted to immediately prevent further operation of platform lift 110 (step 206).
  • step 204 if it is ascertained in step 204 that platform lift 110 is currently moving between the ground floor 121 and the first floor 122, locking device 130 is adapted to allow termination of this current transport movement (step 205).
  • this transport is terminated, i.e. platform 111 has arrived in the ground floor 121 or the first floor 122, locking device 130 is adapted to prevent further operation of platform lift 110 (step 206).
  • locking device 130 even after de-activation of the platform lift 110 as described above, will continue to allow operation of ramp 112. Thus, a user on platform lift 110 can still safely leave the platform 111.
  • locking device 130 continues checking whether the predetermined condition has been met (step 203) even after lapse of the operating interval without the operating condition having been met. Thus, if a predetermined operating condition is met at a later time, i.e. after lapse of the original operating, it can be ensured that platform lift 110 is re-activated.
