Abstract
Description
- The present invention relates to a stair lift, in particular chair stair lift.
- These devices are known in the art, and serve to provide transportation of a person with impaired stairclimbing mobility up and down the stairs. Such stair lifts are for instance known from the international patent applications
WO2014/098573 ,WO2014/098574 andWO2014/098575 in the name of the same applicant, but other, less refined equivalents exist too. - These particular stair lifts in general comprise a rail, which forms the track along a stair, which rail may in numerous situations be curved. The seat of the stair lift follows the curved rail, which may lead to some rocking or inclement of the seat during movement. The seat may therewith incline too, which causes the risk of a person sliding off the seat. In order to prevent such unwanted occasion, a provision may be present for balancing the seat. Such provision may be an automated balancing system, with electr(on)ic actuators. These systems are known in the art as well, and the European Patent
EP 1037846 in the name of the present applicant, which is herewith incorporated by reference, gives a good overview of the state of the art. - However, these actuators may unexpectedly refuse or fail, which leads to dangerous situations. In particular the risk of failing is quite high in systems comprising a worm drive for leveling the seat. After years of operation the worm drive may be worn out, so that the worm may suddenly disengage the gear of the worm drive.
- It is therefore an object of the present invention to provide a solution for the above mentioned disadvantages, or at least to provide a useful alternative to the known prior art.
- The invention thereto proposes a stair lift, comprising at least one rail extending along a track, a frame, suspended on the at least one rail, and comprising a drive, for moving the frame along the rail, a support for a seat, movable, in particular pivotable with respect to the support, a balancing system, for keeping the seat in a predetermined orientation with respect to a fixed world and a lock for locking the movement of the seat with respect to the support.
- The locking system prevents the seat to get in undesired angles with respect to the frame, and thus indirectly with respect to the fixed world. It is to be understood that the lock may be a separate part of the stair lift, and not - for instance - just a software routine in the balancing system. In particular, the lock may be a mechanical lock, which, at least in order to activate, does not comprise electronic actuators. In particular the brake is spring biased.
- In an embodiment, the lock is configured to lock the movement of the seat with respect to the frame when the seat is moved more than a predetermined angle. The lock may comprise detection means for detecting that the predetermined angle was reached. In particular these may be mechanical detection means, such as a hole or protrusion.
- The predetermined angle may be defined with respect to the frame, or with respect to the fixed world, and may for instance be 5 or in particular 10 degrees.
- In an embodiment, the lock comprises a latch. Such latch may be spring-biased, and may comprise an actuator for unlocking the actuator. The spring based latch may engage with a hole, positioned such that the latch locks thanks to the spring when the predetermined angle is reached.
- In a preferred embodiment, the lock comprises a brake, which may in particular be a drum brake or a disk brake.
- The lock may further be configured for disabling the balancing system when it is locked, or initiate an immediate correction of the balancing system when the predetermined angle was reached, in order to prevent a person positioned in the locked angle for a long time.
- Preferably, in a locked state the latch is torque proof connected with a counterpart, in particular a gear. The latch may be connected to the frame, and the counterpart may be connected to the seat, or vice versa. Thus in the locked state the frame and the seat are torque proof connected with each other.
- The lock may further be configured for disabling a drive, for moving the frame part along the rail when it is locked, so that no person is moved with the lift while sitting under an angle.
- In a particular embodiment the balancing system comprises a worm drive, having a worm spidle and a worm gear engaging each other. The worm spindle is mounted at the support and driven by a motor. The worm gear is mounted to the seat. The lock comprises an anchor, which can be brought into torque proof engagement with the worm gear, in particular with the worm teeth of the worm gear. The anchor may be attached to the frame.
- In a preferred embodiment the, the worm drive further comprising a worm spindle engaging the worm gear, the worm gear has a at least one first area for exclusively engaging with the worm spindle, the worm gear has at least one second area for exclusively engaging with the latch. This embodiment enables that the same ring gear is used for being engaged by the latch and being engaged by the spindle. Thus merely one standard gear can be used as the worm gear. Nevertheless the teeth of the gear, which are to be engaged by the latch, can not be worn-out by the permanent interaction between the spindle and the gear. Thus in case of emergency the latch interacts with fresh teeth of the gear, enabling a secure safety interaction between the gear and the latch even if the worm gear is worn-out. The first area may be mutually spaced in circumferential direction from the second area, and/or the first area may be mutually spaced in axial direction from the second area.
- Preferably the latch mechanism may be configured as a self-energizing mechanism. That means that in case of engagement of the latch, the force which keeps the latch in its locked state will increase if the seat tends to further deflect from the horizontal orientation (inclination increases).
- In a preferred embodiment, in a locked state the latch is adapted to follow the movement of the counterpart and being biased by the counterpart against a biasing element, in particular a biasing face, the biasing face is adapted to additionally bias the latch into its locked position, in particular in a radial direction to the center of the gear. So the further the seat is deflected from its horizontal position, the further the latch is biased against the biasing face, the further the biasing face biases the latch in direction of the center of the gear and thus into the locked state.
- The invention will now be elucidated into more detail with reference to the following figures, herein:
-

The stair lift comprises arail 1 extending along a track, aframe 2, suspended on therail 1, and a drive (not visible), for moving theframe 2 along the rail; a support 7 for aseat 3, which is movable, in particular pivotable with respect to theframe 2. Thestair lift 1 comprises abalancing system 4, for keeping the seat in a predetermined uninclined orientation with respect to a fixed world, provided with a lock for locking the movement of the seat with respect to theframe 2. Embodiments of the lock are depicted infigures 3 to 7 . -
Figure 2 shows a the stair lift fromfigure 1 in an undesired inclined position; -
Figure 3 shows a first embodiment of a brake for the stair lift fromfigures 1 and 2 , wherein the brake comprises adrum brake 5. -
Figure 4 shows a second embodiment of a brake for the stair lift fromfigure 1 and 2 , wherein the brake comprises a disk brake 6. -
Figure 5 shows a third embodiment of a brake for the stair lift formfigure 1 and 2 . The brake comprises alatch 14 in the form of ananchor 14. - In this embodiment the
balancing system 4 comprises aworm drive 10 having aworm spindle 11 and aworm gear 12. Theworm spindle 11 is driven by a balancing motor M and is mounted at theframe 2. Thespindle 11 is in engagement with the worm gear, which is connected to theseat 3. The further thegear 12 is rotated against thespindle 11 the further theseat 3 is angled against theframe 2. - The
latch 14 is mounted on theframe 2. When thelatch 14 engages thegear 12, theseat 3 is rotationally fixed to theframe 2, only a limited turn of approx. 2° may be possible, caused by an optional linear guiding 19, which is pivotably flexible in small amount, as described later with reference tofigure 7 . - The
latch 14 is biased by aloading spring 16 into a locked position.Figure 5 shows thelatch 14 in its unlocked position. For holding thelatch 14 in its unlocked position anactuator 17, in particular a solenoid actuator, is provided. In case of emergency theactuator 17 is deactivated, so that theloading spring 16 can urge thelatch 14 into its locked position, as illustrated infigure 6 . The deactivation can be initiated with the help of an orientation sensor system, e.g. as explained in the European patent application16154071.1 - The
latch 14 is supported in thehousing 18 of theframe 2 by means of a linear guiding 19. The guiding 19 is supported flexibly in thehousing 18 by means of centeringmeans 21. The centering means 21 can be realized by springs or by any elastic material, which may produce an elastic counteracting force compression. Infigure 7 it is shown that the linear guiding 17 can be deflected in a small amount perpendicular to the main direction (double arrow P,fig. 6 ) of the linear guiding 19. - During the locked state the
latch 14 can follow the rotational movement of the gear 12 (seefigure 7 ). To stop this movement after certain degrees of movement a biasingface 20 is provided, against which thelatch 14 is biased during following. The biasingface 20 is inclined radially towards the center of thegear 12, so that upon contact between thelatch 14 and the biasingface 20 thelatch 14 is biased against thegear 12, additionally to the loading force of theloading spring 16. So the brake is in this embodiment designed self-energizing using of the weight of the seat including any load sitting on the seat. -
