Abstract

A device, in particular a stair lift, for conveying a person from a first level to a second level, comprising a rail (2) which extends between the first and the second level, a frame (3) which is provided with engaging means designed to engage the rail (2) in such a manner that the frame (3) can be moved along the rail (2), driving means designed to cause the frame (3) to move along the rail (2), and a support (5), in particular a chair, on which the person can be seated, which stair lift is furthermore provided with control means designed to activate the driving means, wherein the control means comprise at least a touch-sensitive surface (9), which surface extends or may extend in such a manner that a person can rest his or her hand, or a part thereof, on the surface so as to activate the driving means.

Claims

1. A device, for conveying a person from a first level to a second level, comprising:

a rail which extends between the first and the second level;

a frame which is provided with engaging means designed to engage the rail in such a manner that the frame can be moved along the rail;

driving means designed to cause the frame to move along the rail;

a support, on which the person can be seated;

control means designed to activate the driving means,

wherein the control means comprise at least one touch-sensitive surface sensitive to a contact point made by the person upon touching the touch-sensitive surface, said control means being able to determine a location of the contact point on said touch sensitive surface, which surface extends or can be arranged to extend such that a person can rest his or her hand, or a part thereof, on the surface,

wherein a portion of the said touch-sensitive surface is designated as a predetermined part of the surface,

wherein the control means are configured to activate the driving means and cause the frame to move along the rail when the control means determine when the hand of the person, or a part thereof, makes a specified movement on the touch-sensitive surface, wherein the specified movement is a movement made by the hand of the person, or a part thereof, to move an image displayed on the touch-sensitive surface, and

wherein the control means are configured to activate the driving means and cause the frame to move along the rail as long as the hand, or a part thereof, maintains contact on the predetermined part of the surface and to deactivate the driving means when the control means determine that the hand, or a part thereof, is no longer in contact with the predetermined part of the surface.

2. A device according to claim 1, wherein the touch-sensitive surface is a touch-sensitive screen, wherein the control means are furthermore designed to display at least an instruction, an image of a control button and/or a message on the screen.

3. A device according to claim 2, wherein the control means are designed to display an image of a control button on the screen, which image can be moved across the screen according to the specified movement made by the person on the touch-sensitive surface.

4. A device according to claim 2, wherein the control means are furthermore designed to receive a code by means of buttons being displayed on the touch-sensitive screen, and to compare said code with a code stored in the control means, such that the driving means can only be activated to cause the frame to move along the rail after it has been determined that the received code corresponds to the stored code.

5. A device according to claim 1, wherein the support is a chair provided with at least one armrest, and wherein the touch-sensitive surface extends on said at least one armrest.

6. A device according to claim 1, wherein the touch-sensitive surface extends on a unit, which can be detached from the frame, wherein said unit and the frame comprise wired or wireless communication means for activating the driving means.

7. A device according to claim 1, wherein the device is a stair lift.

8. A device according to claim 1, wherein the support is a chair.
