  • the locking part displacer 20 may be connected to one of the parts 72, 72, and the housing may be fixed to the other part 71, 72 of the building aperture cover 70.
  • the housing 7 may be attached to a fixed frame of the building aperture cover 70, and the actuator system may be attached, such as by means of the locking part displacer 20, to the part to be opened, such as a window sash or door, or vice versa.
  • Fig. 9 illustrates schematically an embodiment of the present disclosure, wherein an unlocking position displacement system 80 is configured to automatically arrange the locking part 10 in the unlocked position POS2.
  • the unlocking position displacement system 80 may in one or more embodiments of the present disclosure be a spring system 80 configured to automatically arrange the locking part displacer 20 in the position providing that the locking part 10 is moved to the unlocked position POS2.
  • This spring system 80 may e.g. be arranged between the chain linking part 30 and the locking part displacer 20 and/or between the locking part displacer 20 and the locking part 10.
  • the spring system 80 may e.g. be arranged between the chain linking part 30 and the locking part displacer 20, so that the locking part displacer 20 is forced to be displaced to move the locking part 10 to the unlocking position POS2 by a pushing force F2 provided by the spring system 80.
  • the spring system 80 may in one or more embodiments of the present disclosure comprise a tension spring, a compression spring, a coil spring, a compression spring, a flat/plate spring and/or the like.
  • Fig 10 shows an upper graph indicating pulling force F1 over time and the force threshold FTH provided by the spring system 80, and the lower graph illustrates the locking part position in accordance with the upper graph. As illustrated, as long as the pulling force F1 is below the force threshold FTH in the time span tO-tl (see upper graph of fig. 10 ), the locking part 10 is kept in the unlocking position POS2, (see lower graph of fig. 10 ).
  • the locking part 10 When the pulling force F1 exceeds the force threshold FTH in the time span t1-t2, the locking part 10 is moved to the locking position POS1. When the pulling force F1 gets below the threshold FTH again at t2, the locking part 10 is moved back to the unlocking position POS2 by the unlocking position displacement system 80.
  • a force sensor such as a stain gauge system or the like (not illustrated) may detect the pulling force F1 provided in the chain.
  • an electronically actuated unlocking position displacement system (not illustrated) may be configured to displace the locking part 10 between the locking position POS1 and unlocking position POS2 dependent on the registered force value or a derivative parameter thereof, e.g. as illustrated in fig. 10 .
  • Figs. 11a-11c illustrates schematically further, various embodiments of the present disclosure, relating to the interaction between the locking part 10, locking part displacer 20 and the chain linking member 30.
  • the displaceable connection(s) allowing a relative displacement between the one or more chain linking member(s) 30 and said one or more locking part displacers 20 may be provided by a displaceable rail connection.
  • the chain linking member 30 may comprise rail members 92 at least partly enclosing end or side edges 93 of the locking part displacer in order to guide the displacement between these when a pushing or pulling force is provided, e.g. to assure a substantially linear or alternatively controlled, curved movement between the chain linking member(s) 30 and the locking part displacer 20.
  • the pin 21 extends in fig. 1 1a through the opening 26 in the locking part displacer and is guided in the guiding track 22. See e.g. also e.g. figs. 1a-2c .
  • Fig. 11b illustrates an embodiment of the present disclosure, where the locking part displacer 20 comprises a recessed trail/slit 96 into which connection rails or protrusions 95 extend.
  • This connection allows a relative, e.g. linear or guided, curved movement between the chain linking member(s) 30 and the locking part displacer 20 when a pushing or pulling force is provided.
  • Fig. 11c illustrates an embodiment of the present disclosure, where two locking parts and two chain linking members are provided, see e.g. also figs. 2a-2c .
  • the locking part displacer 20 is arranged between the chain linking members 30, and the chain linking members 30 are arranged between the locking part displacer 20 and individual locking parts 10.
  • the locking part displacer 20 and chain linking members 30 are displaceable connected by a rail arrangement to provide the guided movement/displacement between the locking part displacer 20 and the chain linking members when the pushing or pulling force is provided.
  • Figs. 12-13 illustrated embodiments of the present disclosure, where the displacement system 1 is mounted to open and close a top-hinged building aperture cover in the form of a roof window 70 installed in a roof 75.
  • Fig. 12 illustrates an embodiment of the present disclosure, where the displacement system 1 is mounted to open and close a top-hinged building aperture cover in the form of a top-hinged roof window 70.
  • the system 1 comprises the locking system comprising the locking part displacer 20 and locking part 10 as e.g. previously described (not illustrated in fig. 12 ) according to various embodiments of the present disclosure.
  • the top hinged window provides a pushing force F2 due to gravity so as to move the locking part to the unlocking position POS2, se previous figures.
  • the roof window is a centre-pivot roof window 70 controlled by the displacement system 1.
  • the window may, due to that it is a centre-pivot window, not provide enough force itself to assure that the locking part 10 is arranged in the unlocking position during closing of the window, and thus, e.g. a unlocking position displacement system 80 as previously explained may be relevant to install.
  • the window 70 controlled by the displacement system 1 may be a vertically mounted window or door placed in an outer, vertical wall of a building, and where the widow's 70 pane will be arranged substantially vertical when closed.
  • the drive system 1 may be paced in a housing 7 that is to be mounted on a building aperture cover frame part 71, 72, or the housing 7 may be an integrated part of a frame arrangement of the building aperture cover 70.
  • One or more hinge connections 77 provides that the building aperture cover frame parts 71, 72 can move relative to each other, while the hinge connections carry at least a part of the frame and glass pane(s) of the building aperture cover 70.
