• This invention concerns a method for the displacement of a vertically displaceable motor- driven door leaf 1 in an opening 2 in a building 3. See Figures 1 and 2.
• a first line drum 4 comprising a first axis of rotation 5 is caused to interact with a first line 6 that is attached to the line drum 4 and the door leaf 1.
• a second line drum 7 comprising a second axis of rotation 8 is caused to interact with a second line 9 that is attached to the line drum 7 and the door leaf 1.
• the two lines 6 and 9 are attached one on each side of the door leaf 1 , on the principally vertically directed sides 1a and 1b of the door leaf 1 that are directed towards the principally vertically directed side sections 2a and 2b of the opening that limit the opening in the sideways direction. See Figures 3-1 1.
• a force of rotation is transferred from a motor unit 10 to the relevant axis of rotation 5 and 8 of the line drums through a power-transfer unit 11 , whereby the line drums 4 and 7 rotate.
• the first line 6 is rolled onto or rolled off from the first line drum 4 and the second line 9 is rolled onto or rolled off from the second line drum 7, whereby the door leaf 1 is displaced upwards or downwards.
• the power- transfer unit 1 1 is caused to act on at least one axis of rotation 5 or 8 since two cogs are always in interaction with each other in a gear system 12 comprised within the power-transfer unit 11 , and it acts on at least one axis of rotation 5 or 8 whereby at least this one axis of rotation 5 or 8 rotates.
• the force of rotation output from the motor unit, the rate of revolution is geared to become a suitable force, rate of revolution, for the displacement of the line and for the rotation of the line drum through the use of the gear system 12.
• a transmission unit 13 is caused to interact with the first axis of rotation 5 and the second axis of rotation 8, and this transmission unit ensures that the rotation of the axis of rotation that is caused to rotate with the aid of the power-transfer unit 1 1 is transferred to the second axis of rotation.
• the transmission unit 13 ensures that the two axes of rotation 5 and 8 are rotated at the same speed, which causes the door leaf 1 to be displaced upwards or downwards evenly and equally at its two sides.
• This method with the aid of the power-transfer unit 11 and the transmission unit 13 ensures transfer of the power of the motor unit to the line drums 4 and 7, which can continue to rotate, albeit at a lower speed, even if certain parts of the power-transfer unit 11 should suddenly cease to function for any reason.
• the motor unit 10 can in this case, during disturbances in function of the power-transfer unit 11 , be used to brake the displacement of the door leaf both upwards and downwards by braking the rotation of the axes of rotation, the rotation of the line drums, and in this way prevent the displacement of the lines and the door leaf since it will always be possible to cause the motor unit 10 to influence one of the axes of rotation 5 or 8 and to influence the braking function on one of the axes of rotation 5 or 8, which will be transferred to the second axis of rotation 5 or 8.
• Two cogs that are always in interaction mean that the motor unit 10 can always apply a force to at least one of the axes of rotation 5 or 8, and the transmission unit 13 makes it possible to transfer rotational force or braking force from the axis of rotation 5 or 8 that has a force applied to it to the axis of rotation 5 or 8 that for some reason does not have a force applied to it directly by the motor unit 10.
• a first gear 14 and a second gear 15 that are comprised within the gear system 12 are connected to the motor unit 10 and each one of them to one of the axes of rotation 5 or 8 of the line drums.
• Each gear 14 and 15 is caused to change the gearing of the rotation that is output from the motor unit and makes possible the setting and the adjustment of a suitable force, rate of revolution, for the displacement of the relevant line and the rotation of the relevant line drum. Even if one of the gears 14 or 15 is not working in the proper manner, the rotation from the one axis of rotation 5 or 8 at which the gear is working can be transferred to the other axis of rotation 5 or 8.
• the method can be carried out using a motor 16 such that the force of rotation from this motor 16, which is comprised within the motor unit 10, is transferred to the first axis of rotation 5, the line drum 4, and to the second axis of rotation 8, the line drum 7.
• a motor 16 it will not be possible to transfer a force of rotation to either axis of rotation if the motor is in some way faulty, but it will, however, be possible to use the braking ability of the motor such that the door leaf 1 is braked and stopped and is not erroneously displaced if a problem arises with the motor unit 10 itself or with the motor 16. See Figures 5 and 6.
• the gear system 12 comprises thus the first gear 14 and the second gear 15 that are coupled to the motor 16 of the motor unit, to at least one rotating output axis 17 from the motor unit, and each is coupled to the axis of rotation 5 or 8 of the relevant line drum.
• two motors 18 and 19 are used, comprised in the motor unit 10, such that the force of rotation from a first motor 18 comprised within the motor unit 10 is transferred to the first axis of rotation 5, the line drum 4, and where the force of rotation from a second motor 19 comprised within the motor unit 10 is transferred to the second axis of rotation 8, the line drum 7. See Figures 7-9.
• the gear system 12 thus comprises the first gear 14 that is located between the first motor 18 of the motor unit and the axis of rotation 5 of the first line drum, and the second gear 15 that is located between the second motor 19 of the motor unit and the axis of rotation 8 of the second line drum.
• the power-transfer unit 11 ensures that two cogs are always in interaction such that the force of rotation of at least one motor can be transferred to one axis of rotation 5 or 8, such that it can be caused to rotate, and that the rotation of this axis 5 or 8 can be transferred to the second axis of rotation 5 or 8 through the transmission unit 13.
• a detection arrangement 20 is caused to continuously detect the instantaneous power consumption of the motor unit 10 during rotation of the line drums 4 and 7.
• a comparator 21 is caused to compare the instantaneous power consumption with a specified permitted power consumption within an interval.
• a power consumption that lies outside of the specified interval suggests that the load on the drive unit has increased or decreased, which in both cases suggests that there is a fault or problem with the motor unit, the power-transfer unit 11 , the gear system 12, the line drums 4 and 7, the lines 6 and 9, the door leaf 1 or something else that influences the displacement of the door leaf.
• a level of power consumption outside of the specified interval indicates that continued operation of the door leaf 1 may constitute a danger.
• At least one of a brake 22 and a shut-down unit 23 is brought into its working condition if the instantaneous power consumption lies outside of the specified interval, and acts on the motor unit 10 such that the motor unit 10 is braked or shut down if the instantaneous power consumption lies outside of the specified interval.
