Stairlift
A stairlift may include a rail, a chair with an armrest, a carrier that has a drive motor and is drivable along the rail, a control unit, and a first input device located at the at least one armrest and configured to provide a signal to the control unit to transport a user in a first driving direction. The control unit may start or stop a movement of the carrier in the first direction based at least on the signal of the first input device. The stairlift may also include a second input device that is separate from the first input device, and configured to provide a signal to the control unit to transport the user in the first driving direction. Further, the control unit may be adapted to start or stop the movement of the carrier based on the signal of the second input device.
1. A stairlift comprising:
a rail;
a chair having at least one armrest;
a carrier having a drive motor, wherein the carrier is drivable along the rail;
a control unit;
a first input device disposed at the at least one armrest, the first input device being configured to provide a signal to the control unit to transport a user in a first driving direction, wherein the control unit is configured to start or stop a movement of the carrier in the first driving direction based at least on the signal of the first input device; and
a second input device separate from the first input device and disposed at the at least one armrest, wherein the second input device is configured to provide a signal to the control unit to transport the user in the first driving direction, wherein the control unit is configured to start or stop the movement of the carrier in the first driving direction based on the signal of the second input device.
2. The stairlift of claim 1 comprising a safety sensor configured to provide a safety sensor signal, wherein the control unit is configured to stop the movement of the carrier in the first driving direction in response to the safety sensor signal.
3. The stairlift of claim 2 wherein the control unit is configured to overrule the safety sensor signal by the signal of the second input device.
4. The stairlift of claim 1 wherein the control unit is configured to start operation of the stairlift in response to the signal of the second input device only if a movement operation of the carrier in the first driving direction is not possible as a response to the signal of the first input device.
5. The stairlift of claim 1 comprising an emergency stop input device, wherein the control unit is configured to overrule the signal of the second input device by a signal of the emergency stop input device.
6. The stairlift of claim 1 comprising a collision sensor configured to provide a safety signal, wherein the control unit is configured to stop the movement of the carrier in the first driving direction in response to the safety signal.
7. A stairlift comprising:
a rail;
a chair;
a carrier having a drive motor, wherein the carrier is drivable along the rail;
a control unit;
a first input device disposed at the chair, the first input device being configured to provide a signal to the control unit to transport a user, wherein the control unit is configured to start or stop a movement of the carrier based at least on the signal of the first input device; and
a second input device separate from the first input device and disposed at the chair, wherein the second input device is configured to provide a signal to the control unit to transport the user, wherein the control unit is configured to start or stop the movement of the carrier based on the signal of the second input device.
8. The stairlift of claim 7 comprising a safety sensor configured to provide a safety sensor signal, wherein the control unit is configured to prevent or stop the movement of the carrier in response to the safety sensor signal.
9. The stairlift of claim 8 wherein the control unit is configured to overrule the safety sensor signal by the signal of the second input device.
10. The stairlift of claim 7 wherein the control unit is configured to start operation of the stairlift in response to the signal of the second input device only if movement of the carrier is not possible as a response to the signal of the first input device.
11. The stairlift of claim 7 comprising an emergency stop input device, wherein the control unit is configured to overrule the signal of the second input device by a signal of the emergency stop input device.
12. The stairlift of claim 7 comprising a collision sensor configured to provide a safety signal, wherein the control unit is configured to stop the movement of the carrier in response to the safety signal.
