A device for reversibly connecting a rehabilitation mechanism to a bed, in particular to a hospital bed that can be brought to a vertical position, the device at least comprising: - at least one connection element arranged on the rehabilitation mechanism; - at least one receiving unit, which can be arranged at the side of and/or at the foot end of the bed; - wherein the receiving unit corresponds in design to the connection element; and - a transport means for transporting the rehabilitation mechanism toward the bed and away from the bed; - wherein the transport means and/or the bed are/is height-adjustable; characterized in that - in use at a transverse side of the bed, a connection frame is arranged extending at least along a portion of the transverse side, which connection frame is mounted pivotably about a pivot axis with respect to the one or more receiving units; - the at least one receiving unit or, in the case of several receiving units, at least one receiving unit comprises a locking device which is configured to come into operative connection with the connection frame; - a trigger means is arranged on the transport means, for directly or indirectly interacting with the at least one receiving unit or, in the case of several receiving untits, with at least one receiving unit; - and wherein the transport means is configured in such a way that, for releasing and for fixing the rehabilitation mechanism, it interacts with the at least one receiving unit or, in the case of several receiving units, with at least one receiving unit; by virtue of the fact that, when the trigger means arranged on the transport means approaches the bed, it presses against a connection frame and, for fixing the rehabilitation mechanism in the receiving unit or units, while the transport means moves away from the bed, the pressure exerted by the trigger means on the locking device decreases. - at least one connection element arranged on the rehabilitation mechanism; - at least one receiving unit, which can be arranged at the side of and/or at the foot end of the bed; - wherein the receiving unit corresponds in design to the connection element; and - wherein the receiving unit corresponds in design to the connection element; and - a transport means for transporting the rehabilitation mechanism toward the bed and away from the bed; - wherein the transport means and/or the bed are/is height-adjustable; - wherein the transport means and/or the bed are/is height-adjustable; - in use at a transverse side of the bed, a connection frame is arranged extending at least along a portion of the transverse side, which connection frame is mounted pivotably about a pivot axis with respect to the one or more receiving units; - the at least one receiving unit or, in the case of several receiving units, at least one receiving unit comprises a locking device which is configured to come into operative connection with the connection frame; - a trigger means is arranged on the transport means, for directly or indirectly interacting with the at least one receiving unit or, in the case of several receiving untits, with at least one receiving unit; - and wherein the transport means is configured in such a way that, for releasing and for fixing the rehabilitation mechanism, it interacts with the at least one receiving unit or, in the case of several receiving units, with at least one receiving unit; by virtue of the fact that, when the trigger means arranged on the transport means approaches the bed, it presses against a connection frame and, for fixing the rehabilitation mechanism in the receiving unit or units, while the transport means moves away from the bed, the pressure exerted by the trigger means on the locking device decreases.
