Technical Field

The invention relates to a seat elevator.

background

WO 2013/129923 a1 discloses a stairlift. The stairlift comprises a seat mounted on a load carrier. The carrier travels along at least one guide rail. A leveling mechanism is provided to always maintain the seat in a horizontal orientation even when the inclination of the guide rails changes.

Conventional stairlifts are equipped with an emergency lowering device. If a fault occurs while the carrier is traveling, the stairlift can be manually lowered down. Thus, the rod is mounted within an "easy reach distance"; when activated, the elevator will slowly descend. The user does not have to go up and down the elevator midway the stairs but can wait for a safe stopping point.

The lever has a higher priority than the emergency stop button. Thus, if the emergency stop button is pressed, the user is still able to activate the downward movement of the carrier by means of the activation lever. For safety reasons, in particular to prevent misuse of the descent function, the lever is only positioned within an "easy-to-reach distance", for example as a bowden cable positioned at the carrier, but not very ergonomic. For some disabled people, the pole is practically not at all reachable.

Disclosure of Invention

the aim of the invention is to improve the ergonomics of the stairlift with regard to the emergency lowering function, but a high safety standard should be maintained. The object of the invention is solved by a stairlift according to claim 1; preferred embodiments are subject of the dependent claims and the description.

the seat elevator of the present invention includes:

the track is provided with a track which is provided with a plurality of tracks,

A seat having at least one armrest,

a carrier having a drive motor, the carrier adapted to be driven along the track,

A first input device positioned at one of the handrails, the first input device being adapted to provide a signal to the control unit that the user wants to travel in a first driving direction, in particular upwards or downwards,

A control unit adapted to start or stop movement of the carrier in the first direction based at least on a signal of the first input device.

According to the invention, a second input device separate from the first input device is positioned at one of the handrails, the second input device is also adapted to provide a signal to the control unit that the user wants to travel in the first driving direction, and the control unit is adapted to start or stop movement of the carrier in the first direction based on the signal of the second input device.

the invention proposes to arrange a user input device at the armrest for activating the emergency lowering device. Here, the button can be reached by almost everyone without departing from the position.

in an embodiment, a safety sensor, in particular a crash sensor, is mounted at the seat elevator, which is adapted to provide a safety sensor signal; the control unit is adapted to stop the movement of the carrier, in particular in the first driving direction, as a response to the safety sensor signal. The safety sensor may be any sensor or electronic device capable of detecting conditions in the area of the stairlift. Radar monitoring instruments comprising sophisticated analysis software may also be considered as safety sensors.

in a preferred embodiment, the control unit is adapted to overrule the signal of the (over) safety sensor by a signal of the second input device. Thus, in the event that the carrier becomes jammed due to the crash sensor signal, the user has the ability to force the carrier to continue moving.

In an embodiment and in order to improve safety, the control unit is adapted to start the operation of the stairlift in response to the signal of the second input device only if an operation is not possible in response to a movement of the carrier in the first direction as a response to the signal of the first input device. Thus, the user can force the carrier to move by means of the second input means only in case the first input means is "inactive".

in an embodiment the stairlift comprises an emergency stop input device, wherein the control unit is adapted to overrule the signal of the second input device by the signal of the emergency stop input device. In contrast to the prior art, the emergency stop input device has the highest priority and can override in particular all other input devices and sensors.

The signal may be an analog signal or a digital signal; it is also contemplated to use as a signal a "power off" signal, which is typically used in conjunction with an emergency stop switch.

The input device is intended to receive user commands. The security sensor is not considered an input device.

Detailed Description

Fig. 1 and 2 show a stairlift 1 of the invention. The stairlift 1 comprises a rail 2 and a load carrier 3, which load carrier 3 travels along the rail 2 in an upward direction V2 or a downward direction V1. A chair 4 having a seat, backrest, footrest and armrests 11 is mounted on a levelling platform 5. A levelling platform 5 is mounted on the carrier 3. In order to always keep the levelling platform 5 in a constant orientation, a levelling mechanism (not shown) is provided between the carrier and the levelling platform 5, which levelling mechanism supports the levelling platform 5 in such a way that it can rotate along the horizontal axis H relative to the carrier 3. Thus, the levelling means is adapted to always keep the levelling platform 5 in a constant orientation when the orientation of the carrier 3 changes during driving along the track 2.

The function of the stairlift 1 is controlled by a control unit 6. Fig. 3 shows an armrest 11 with a first input device 7, here a two-way joystick 7. By moving the joystick 7, the user can trigger a signal to the control unit 6 that the user wants to travel e.g. downwards (first driving direction). The crash sensor 10 is arranged, for example, at a foot pedal (other positions are also possible). When the collision sensor 10 detects a collision with an obstacle during the downward movement, the control unit 6 stops the movement of the carrier 3. For disabled persons this can be a very unpleasant situation. In this case, the control unit prevents further operation of the load carrier, in particular downward movement, for safety reasons. In the worst case, the load carrier may get stuck in the middle of the stairway, especially if additional obstacles are present on the seat lift, thus also preventing upward movement (e.g. bags or clothing falling off the seat on the stairs). A disabled person cannot leave the seat without a significant risk of injury. Alternatively, the carrier may get stuck in the middle of the stairway due to sensor failure.

Independently of the exact reason and according to the invention, the user has the opportunity to give the control unit 6 an additional command that the user wants to travel down to a position where the user can safely leave the seat. Thus, the user may activate the second input means 8 (here a push button), the second input means 8 outputting a further signal to the control unit 6 that the user wants to travel downwards. Even if the collision sensor outputs a stop signal to the control unit, the control unit 6 activates the drive motor 12 to perform the downward movement. Here, the user can decide that the carrier should continue to move contrary to the crash sensor signal. The obstacle can then be removed by the stairlift.

In this case, the collision sensor malfunctions. When the collision sensor detects an obstacle, the drive motor 12 will continue to drive the carrier. An available possibility to stop the drive motor 12 is to press the emergency stop button 9, where the emergency stop button 9 is also attached to the armrest 11.

the second input device 8 thus provides the possibility of activating the drive motor 12 even in the event that the crash sensor 10 "wants" to prevent the carrier 3 from moving further, in particular in the safety mode. In the safe mode, the speed of the carrier may be reduced to reduce the risk of injury. However, safety is reduced during such operation as the crash sensor is rejected by the second input device. The prioritization of the input and sensing devices 7-10 is shown in the block diagram of fig. 4.

in order to prevent misuse of the second input device 8, the control unit 6 may be adapted to activate operation of the carrier 3 only in response to a signal from the second input device 8 if the drive motor 12 cannot be activated by the first input device 7, in particular if the safety sensor 10 prevents further movement. Thus, if the user initially wants to start moving by activating the second input means 8, the drive motor 12 will not start running. The user is thus forced to use the normal operating mode first by using the first input device 7, otherwise the stairlift will not be operated. Activation of the drive motor 12 by means of the second input device 8 is only permitted if normal operation is prevented, in particular due to a sensor failure.
