Definitions

  • the disclosure relates to an electric drive system for moving a window-related element such as e.g. a roof window sash, an awning, a blind, or a shutter between open and closed positions.
  • a window-related element such as e.g. a roof window sash, an awning, a blind, or a shutter between open and closed positions.
  • the window-related elements are affected by, e.g., gravity and the unwound hanging load.
  • means need to be provided to ensure that the window-related element remains in position also when the electric drive motor is deenergized. Friction in the mechanism that connects the electric motor to the window-related element can in some circumstances provide sufficient protection against inadvertent movement of the window-related element.
  • the load that acts on the window element is often unpredictable due to wind, snow load, and e.g. the (at the time of production of the window unknown) installation angle of the roof window.
  • a locking system for preventing an output shaft of a main electric motor from rotating, the locking system comprising a mechanical locking arrangement and an auxiliary electric motor, the mechanical locking arrangement being resiliently biased in a first direction to prevent rotation of the output shaft, the auxiliary electric motor being configured to displace the resiliently biased mechanical locking arrangement against the bias, in a second opposite direction, to allow rotation of the output shaft.
  • a locking system which prevents rotation of a motor output shaft by being resiliently biased, but which can be released by means of an auxiliary electric motor, provides a reliable mechanical lock which only requires electrical energy when the main electric motor is in an operating state and the output shaft rotates, while securing the output shaft to prevent it from rotating, when the electric motor is a non-operating state.
  • the system is inherently safe since it will mechanically lock when the electric power is removed.
  • the locking system is configured to allow the output shaft to rotate when the main electric motor is energized, and to prevent the output shaft from rotating when the main electric motor is not energized.
  • the auxiliary motor is energized prior to, or simultaneously as, the main electric motor is deenergized, such that the locking mechanism is released at the latest simultaneously with the start of output shaft rotation.
  • the bias is sufficient to move the mechanical locking arrangement to a locked position when the auxiliary electric motor is not energized, allowing the locking system to be self-locking.
  • the mechanical locking arrangement provides a mechanical interlock preventing rotation of the output shaft.
  • the mechanical locking arrangement comprises a displaceable member such as e.g. a hinged lever.
  • a free end of the displaceable member preferably being resiliently biased towards a towards the output shaft.
  • the mechanical locking arrangement comprises at least one recess such as an axial groove in the output shaft or in a locking rotor mounted on the output shaft, and the displaceable member comprises a tooth shaped protrusion that is sized to fit into the at least one recess.
  • the mechanical locking arrangement comprises a tooth shaped protrusion on the output shaft, or on a locking rotor mounted on the output shaft, and which is sized to fit into the at least one recess, such as e.g. an axial groove, arranged in the displaceable member.
  • the tooth shaped protrusion engages the recess in order to interlock mechanically.
  • the free end of the displaceable member is resiliently biased towards the output shaft by a resilient element such as a spring, and wherein the free end of the displaceable member is moved away from the output shaft against the bias of the spring by, preferably by a rotatable cam or eccentric shaft operably coupled to an auxiliary electric motor.
  • a resilient element such as a spring
  • an electric drive system for driving a window-related element such as e.g. a sash, blind, shutter or awning
  • the electric drive system comprising a main electric motor having an output shaft, the output shaft being configured to rotate about a rotation axis of the output shaft, an actuator configured to apply an external load onto the output shaft, the external load being mainly caused by the weight of the window related element, and the locking system according to the above, the mechanical locking arrangement of the locking system being configured to prevent the output shaft from rotating by engaging the output shaft, the auxiliary electric motor of the locking system being configured to release the mechanical locking arrangement from the engagement with the output shaft, allowing the output shaft to rotate.
  • Such an electric drive system provides a mechanical lock which only requires electrical energy when the main electric motor is in an operating state, i.e. when the window-related element is moving between positions, while preventing the output shaft of the main electric motor from rotating when in a non-operating state, i.e. when the window-related element is stationary, e.g. in an open position.
  • the main electric motor is operably coupled to the window-related element by a drive mechanism, the drive mechanism preferably including a reduction gear.
  • the resilient element is compressed as the cam rotates from the first rotary position to the second rotary position, and is decompressed as the cam rotates from the second rotary position to the first rotary position.
  • the protrusion and the peripheral recess(es) have a longitudinal extension extending parallel to, and in a plane including, the rotation axis.
  • the actuator is a linear actuator, preferably a chain actuator.
  • the mechanical locking arrangement further comprises a support frame, the lever being at least partially enclosed by the support frame, the locking rotor, and the cam.
  • the resilient element extends between the second lever end and the support frame.
  • the resilient element is a spring.
  • a roof window comprising a sash and a frame adapted for receiving the sash, the sash being configured to pivot around a pivot axis so as to open the sash towards an outer side of the window, the roof window further comprising an electric drive system according to the above, the actuator of the electric drive system being adapted for pivoting the sash in relation to the frame against a load of the sash, the sash being maintained in an open position by means of the electric drive system.
  • the sash is maintained in the open position by means of the electric drive system when the electric drive system is not energized, preferably by the electric drive system itself only.
  • Fig. 1 is a diagrammatic illustration of an electric drive system 1 for moving an element 2 related to a window between open and closed positions.
  • the window is a roof window 17 that is installed at an inclination corresponding to the inclination of the roof and the window-related element 2 is a top hung sash.
  • the roof window 17 comprises a sash 2 and a frame 3 adapted for receiving the sash 2, and the sash 2 is configured to pivot around a pivot axis so as to open the sash 2 towards an outer side of the window.
  • sash 2 is shown in an open position by unbroken lines and in a closed position by broken lines.
  • the curved double arrow line illustrates movement of the sash 2. It is understood that the element 2 that relates to a window does not need to be a sash, but could instead be e.g. a blind, shutter, or an awning.
  • the roof window 17 further comprises an electric drive system 1.
  • the electric drive system 1 comprises a main electric motor 4 that is operably coupled to the window-related element 2 by a drive mechanism 6.
  • the main electric motor 4 can e.g. be any suitable AC or DC drive motor with an output shaft 5, such as a tubular linear motor, and is preferably a main electric motor that itself provides some level of braking when it is not energized.
  • the output shaft 5 is coupled to the drive mechanism 6.
  • the drive mechanism 6 comprises, in one embodiment, a reduction gear.
  • the electric drive motor 4 comprises a housing from which the drive output shaft 5 protrudes.
  • the output shaft 5 rotates when the main electric motor 4 is energized and the direction of rotation can be chosen by an operator.
  • the electric drive motor 4 is provided with electrical contacts for connection to electric power.
  • the electric drive system 1 pivots the window-related element/sash 2 in relation to the frame 3 and against a load of the sash 2, the load being mainly caused by the weight of the window-related element but also possibly cause by additional forces due to e.g. wind or build-up of snow.
  • the window-related element/sash 2 is also maintained in an open position by means of the electric drive system 1.
  • the main electric motor 4 of the electric drive system 1 is not energized and the sash 2 is maintained in the open position by means of the electric drive system 1 only.
  • the roof window 17 does not comprise any further support elements, such as gas springs, for maintaining the open sash 2 in position relative the frame 3 against the load of the sash 2.
  • Figs. 2 to 5 show the electric drive system 1 in greater detail.
  • the electric drive system 1 further comprises an actuator 7 configured to apply an external load onto the output shaft 5, the external load being mainly caused by the weight of the window-related element 2, and a locking system 8.
  • the locking system 8 provides a mechanical interlock preventing the output shaft 5 of the main electric motor 4 from rotating, at least temporarily, and comprises mechanical locking arrangement 9 and an auxiliary electric motor 10.
  • the mechanical locking arrangement 9 is resiliently biased in a first direction to prevent rotation of the output shaft 5, preferably in a direction towards the output shaft 5 as shown in Figs. 5 and 6 . Preferably, rotation is prevented by the mechanical locking arrangement 9 engaging the output shaft 5 directly.
  • the auxiliary electric motor 10 is configured to displace the resiliently biased mechanical locking arrangement 9 against the bias, in a second opposite direction, preferably in a direction away from the output shaft 5, to allow rotation of the output shaft 5. The rotation is allowed as the auxiliary electric motor 10 acts to release the mechanical locking arrangement 9 from the engagement with the output shaft 5.
  • the locking system 8 allows the output shaft 5 to rotate when the main electric motor 4 is energized, and prevents the output shaft 5 from rotating when the main electric motor 4 is not energized.
  • the main electric motor 4 is preferably energized when moving the window-related element/sash 2 between positions, and deenergized when the window-related element/sash 2 is stationary in an open position.
  • the auxiliary motor 10 may be energized prior to, or simultaneously as, the main electric motor 4 is deenergized.
  • the bias of the mechanical locking arrangement 9 may be sufficient to move the mechanical locking arrangement 9 to a locked position when the auxiliary electric motor 10 is not energized.
  • the mechanical locking arrangement 9 comprises a cam 11 configured to rotate about a first axis B parallel with the rotation axis A, which cam 11 is operably coupled to and rotated by the auxiliary electric motor 10.
  • the rotational movement of the cam 11 is illustrated by the curved line with double sided arrows in Fig. 6 .

  • the locking rotor 14 is directly coupled to the output shaft 5 to rotate in unison therewith.
  • the output shaft 5 may, e.g., be provided with an integral key and the locking rotor 14 provided with a central bore with a keyway opening to the central bore.
  • the output shaft 5 is (fittingly) inserted into the central bore with the integral key received in the keyway.
  • the output shaft 5 and locking rotor 14 are allowed to rotate until the lever protrusion 12c aligns with the next coming peripheral recess 15.
  • the bias provided by the resilient element 13 is sufficient to allow the lever protrusion 12c to engage a peripheral recess 15 when the auxiliary electric motor 10 is not energized.
