The movable wall element further comprises at least one upper roller device comprising a wheel element which is capable of engaging the ceiling of the building when the wall element is to be moved across the floor. ## Claims ### Claim at position 1 1-19. (canceled) ### Claim 20 A movable wall element for a building with a floor and a ceiling, the movable wall element comprising at least one lower roller device comprising a wheel element which is capable of engaging the floor of the building when the wall element is to be moved across the floor, wherein the movable wall element further comprises at least one upper roller device comprising a wheel element which is capable of engaging the ceiling of the building when the wall element is to be moved across the floor, wherein the wheel elements of the upper roller device and the lower roller device are movably arranged in the upper roller device and the lower roller device respectively between a first position where the wheel elements are engaging respectively the ceiling and the floor and a second retracted position where the wheel elements are not engaging the ceiling or the floor respectively. ### Claim 21 (depends on 20) The movable wall element according to claim 20, characterized in that the upper roller device and the lower roller device each comprises at least one motor, preferably an electric or electromagnetic motor, which is adapted for moving respective wheel elements between their first and second positions. ### Claim 22 (depends on 20) The movable wall element according to claim 20, wherein the upper roller device and the lower roller device each further comprises an upper locking member and a lower locking member respectively, which are movably arranged in the upper roller device and the lower roller device between a first position where the locking members are engaging respectively the ceiling and the floor and a second retracted position where the locking members are not engaging the ceiling or the floor respectively. ### Claim 23 (depends on 20) The movable wall element according to claim 20, wherein the upper roller device and the lower roller device each comprises at least one motor, preferably an electric or electromagnetic motor, which is adapted for moving the upper locking member and the lower locking member between their first and second positions. ### Claim 24 (depends on 21) The movable wall element according to claim 21, wherein the upper roller device and the lower roller device each comprises a single motor, which is adapted for moving both the upper and lower wheel elements and the upper and lower locking members between their respective first and second positions. ### Claim 25 (depends on 21) The movable wall element according to claim 21, wherein the upper roller device and the lower roller device each comprises at least two motors, preferably two electric or electromagnetic motors, a motor that is adapted for moving the upper and lower wheel elements between their first and second positions and a motor that is adapted for moving the locking members between their first and second positions. ### Claim 26 (depends on 20) The movable wall element according to claim 20, wherein the upper roller device and the lower roller device each comprises at least one motor, preferably an electric or electromagnetic motor, which is adapted for driving the wheel elements of the upper roller device and lower roller device respectively. ### Claim 27 (depends on 20) The movable wall element according to claim 20, wherein the wheel element of the lower roller device is arranged in a fixed position where the wheel element is engaging the floor such that the wall element is capable of rolling on the floor. ### Claim 28 (depends on 20) The movable wall element according to claim 20, wherein the wheel elements of the upper roller device and/or the lower roller device are lockable in the first position of the wheel elements where the wheel elements are in engagement with the ceiling and/or the floor respectively. ### Claim 29 (depends on 20) The movable wall element according to claim 20, wherein wall element further comprises at least one locking device, the locking device comprising a locking member for engagement with the ceiling and/or the floor, the locking member being movably arranged in the locking device between a first position where the locking member is engaging the ceiling or the floor and a second retracted position where the locking member is not engaging the ceiling or the floor respectively. ### Claim 30 (depends on 20) The movable wall element according to claim 20, wherein the at least one locking device comprises a motor, preferably an electric or electromagnetic motor, for movement of the locking member between the first and second positions. ### Claim 31 (depends on 20) The movable wall element according to claim 20, wherein the upper roller device and the lower roller device each comprise a motor, preferably an electric or electromagnetic motor, which are adapted to drive the wheel elements of the upper roller element and the lower roller element respectively. ### Claim 32 (depends on 20) The movable wall element according to claim 20, wherein the movable wall element comprises a connecting element for connection to a second movable wall element. ### Claim 33 (depends on 32) The movable wall element according to claim 32, wherein connecting element is adapted for a rotational movement between the two movable wall elements. ### Claim 34 (depends on 20) The movable wall element according to claim 20, wherein the upper roller
