Definitions

  • the disclosure relates to a roof window comprising a sash and a frame adapted for receiving the sash.
  • the sash is optionally suspended from the frame by means of suspension arms, and the sash is configured to pivot around a pivot axis by means of an actuator so as to open the sash towards an outer side of the window.
  • the push-pull chain of an electrically operated actuator can be collapsed and wound together when subjected to force extending in a first direction perpendicular to the longitudinal extension of the push-pull chain, while reaching and maintaining a straight configuration, or a slightly arched configuration, when being subjected to force extending in an opposite second direction.
  • the push-pull chain is stable enough to carry the weight of the sash and subsequently be used to push the sash open or hold it in an open position.
  • DE 10 2016 203452 shows such an actuator comprising a push-pull chain wherein the main part of the actuator is connected to the window frame, and the push-pull chain is visibly connected, to an inner or side surface of the sash, by means of a pivotable bracket and pin combination.
  • DE 102 06 274 , EP 1 422 374 , DE 202 04 224 , and US 2 755 122 show other actuator solutions comprising push-pull chains.
  • Such a push-pull chain actuator has to be individually adapted to fit the specific dimensions of the roof window, since the radius of the push-pull chain determines the size of the window sash.
  • 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 sash optionally being suspended from the frame by means of suspension arms, each optional suspension arm extending at least partially between the sash and the frame, the roof window further comprising at least one actuator adapted for pivoting the sash in relation to the frame against a load of the sash, the load mainly being caused by the weight of the sash, the actuator comprising a push-pull chain and a bracket, the bracket being rigidly connected to a first end of the push-pull chain, a second end of the push-pull chain being received in an actuator housing connected to the frame, the push-pull chain being adapted for bending freely in a first direction, past a configuration in which the push-pull chain forms a straight line, and only to a limited extent past the straight line configuration
  • This solution provides a roof window having an actuator which is stabilized by a stabilizing force, generated by the load of the sash, and which assists in preventing accidental collapse of the push-pull chain of the actuator. Furthermore, an end of the actuator is easily connected to the sash of the roof window after the frame and subsequently the sash have been installed in the roof.
  • the support point is laterally offset from the longitudinal extent of the push-pull chain in the first direction, allowing the push-pull chain to be stabilized when in an end position arched past its straight line configuration in the second opposite direction, which facilitates an actuator which can be used with sashes having different dimensions.
  • the push-pull chain comprises a plurality of coupled links, wherein a last link at the first end of the push-pull chain forms the bracket, allowing the main part of the actuator, including a part of the bracket, to be at least partially collapsed or wound together within the housing.
  • the bracket comprises a second opening adapted for receiving a pre-loading pin, the pre-loading pin extending through the second opening and connecting the bracket to one of the sash and the suspension arm, the load of the sash urging the push-pull chain to bend in the second opposite direction by the pre-loading pin applying the load of the sash onto the bracket.
  • a center axis of the connection pin and a center axis of the pre-loading pin extend parallel with each other and substantially parallel with the pivot axis, allowing the bracket to be pivoted without inducing collapse of the push-pull chain.
  • an open end of the second opening allows the pre-loading pin to at least partially exit the second opening, in a direction parallel with the longitudinal extent of the oblong first opening, if the load applied by the sash is reduced or reversed, preventing collapse of the push-pull chain should the sash be lifted upwards by e.g. wind.
  • the roof window comprises a connecting plate, connected to at least one of the sash and the suspension arm, the connecting plate comprising connection openings aligned with the oblong first opening and the second opening, the connection pin and the pre-loading pin extending through the connection openings of the connecting plate, allowing a simple yet stable connection between actuator and sash.
  • the bracket comprises first and second parallel bracket plates, an oblong first opening in the first bracket plate being aligned with an oblong first opening in the second bracket plate, and a second opening in the first bracket plate being aligned with a second opening in the second bracket plate, the bracket at least partially enclosing the connecting plate such that the first and second bracket plates extend on opposite sides of the connecting plate, facilitating an actuator which distributes force evenly upon the connection pin, the pre-loading pin and, hence, the sash.
  • the actuator comprises locking means engaging the connection pin, the locking means being configured for preventing the connection pin from being removed from the oblong first opening.
  • connection pin comprises a first pin end and a second pin end, the second pin end comprising an enlarged portion too large to pass through the oblong first opening, the first pin end engaging the locking means, the locking means and the first pin end being arranged in a recess within the sash side member or between the suspension arm and the sash, the second pin end being arranged between the frame and the sash or between the frame and the suspension arm.
  • This solution facilitates use of the actuator in a window where the sash is suspended directly from the frame without the use of suspension arms and provides the locking means at a location which is unreachable from the exterior of the building when the sash is closed, as well as a simple and reliable way of interlocking components without, e.g., having to rely on moving parts.
  • the locking means is releasable and comprises at least one of a threaded nut, a spring, a clip, a slider, and a pin, all being reliable and easy-to-operate mechanical solutions for interlocking components.
  • the actuator further comprises a protective casing adapted for enclosing the locking means and the first pin end, further obstructing access to the locking means from the exterior as well as providing protection against external influence such as ingress of dirt, weather conditions, or unintentional mechanical forces such as bending forces.
  • the casing comprises two casing halves, one casing half comprising an access opening allowing access to the locking means such that the locking means can be released from the connection pin, allowing the actuator to be released from the sash, facilitating a secure solution which still allows for simple connection of the actuator to the sash.
  • the actuator further comprises chain support means, connected to at least one of the sash and the frame, adapted for providing a stabilizing force onto the push-pull chain perpendicularly to the longitudinal extension of the push-pull chain, the stabilizing force urging the push-pull chain to bend in the second opposite direction.
  • the roof window is a top-hung roof window comprising one actuator, the actuator being arranged adjacent a frame bottom member.
  • the roof window is a center-pivoted roof window or a top-hung roof window comprising two actuators, each actuator being arranged adjacent one frame side member.
  • Figs. 1a and 1b show a roof window comprising a sash 1 and a frame 2 adapted for receiving the sash 1, the sash 1 being configured to pivot around a pivot axis A so as to open the sash towards an outer side of the window, i.e. towards the exterior of a building.
  • the sash 1 comprises two sash side members 1a, 1b connected to a top sash member 1c and a bottom sash member 1d.
  • the sash 1 may be suspended directly from the frame 2 or, optionally, suspended from the frame 2 by means of suspension arms 3.
  • Each optional suspension arm 3 extends at least partially between a sash side member 1a, 1b and an adjacent frame side member 2a, 2b.
  • At least one actuator 4 is provided to pivot the sash 1 between a closed position and several open positions in relation to the frame 2, open positions being shown in Figs. 1a and 1b .
  • the actuator 4 may furthermore be adapted for securing the sash 1 in the closed position.
  • the actuator 4 is adapted for pivoting the sash 1 in relation to the frame 2 against a load L of the sash 1, the load L mainly being caused by the weight of the sash 1.
  • the load L may also be attributed to external conditions such as e.g. snow resting on the sash or wind.
  • the actuator 4 comprises a push-pull chain 5 and a bracket 6, the bracket 6 being rigidly connected to a first end 5a of the push-pull chain.
  • a second end 5b of the push-pull chain is received in an actuator housing 7 connected to the frame 2, as shown schematically in Fig. 1a .
  • the push-pull chain 5 is withdrawn, completely or almost completely, into the actuator housing 7 by an electrical motor (not shown).
  • the push-pull chain 5 is maintained in the withdrawn position by means of the motor or any other suitable locking means, such that the sash 1 is maintained in the closed position until the actuator 4 is activated in order move the sash 1 to an open position.
  • the push-pull chain 5 comprises a plurality of coupled links 13, as shown in Fig. 2 .
  • the last link 13a at the first end 5a of the push-pull chain forms the bracket 6.
  • the bracket 6 is a separate component connected to the last link 13a of the push-pull chain 5.
  • the push-pull chain 5 bends freely in a first direction D1, at least partially towards the pivot axis A, past a configuration in which the push-pull chain forms a straight line 5c, shown in Fig. 2 , such that at least the main part of the push-pull chain 6 can be collapsed and wound together.
  • the push-pull chain 5 can bend only to a limited extent past the straight line 5c configuration in a second opposite direction D2, allowing the push-pull chain 5 to form an arc.
  • the bracket 6 provides at least one support point S for supporting the load L of the sash 1, as shown in Figs. 4a to 4c .
  • the support point S is laterally offset from the longitudinal extent of the push-pull chain 5 so that the load L of the sash 1 urges the push-pull chain 5 to bend in the second opposite direction D2.
  • connection pin 8 in one embodiment being releasable, connects the bracket 6 to at least one of the sash 1 and the suspension arm 3, preferably one of the side sash members 1a, 1b and/or the suspension arms 3, as shown in Figs. 5a and 5b as well as 6a and 6b.
  • the connection pin 8 has a first pin end 8a and a second pin end 8b as shown in Figs. 3a to 3c .
  • connection pin 8 extends though an oblong first opening 9 in the bracket 6 for securing the push-pull chain 5 to one of the sash 1 and the suspension arm 3.
  • the connection pin 8 is allowed to move in the oblong first opening 9 in the direction of the longitudinal extent of the oblong first opening 9, the longitudinal extent of the oblong first opening 9 being aligned with the longitudinal extent of the push-pull chain 5.
  • the bracket 6 comprises a second opening 17 adapted for receiving a pre-loading pin 18, the pre-loading pin 18 extending through the second opening 17 and connecting the bracket 6 to one of the sash 1 and the suspension arm 3.
  • the second opening 17 is essentially a U-shaped recess having an open end 17a, facing away from the push-pull chain 5, allowing the pre-loading pin 18 to exit the second opening 17 in one direction.
  • the pre-loading pin 18 extends through the second opening 17 and connects the bracket 6 to the sash 1 rigidly.
  • the load L of the sash 1 urges the push-pull chain 5 to bend in the second opposite direction D2 by the pre-loading pin 18 applying the load L of the sash 1 onto the bracket 6.
  • the center axis CA of the connection pin 8 and the center axis CA2 of the pre-loading pin 18 extend parallel with each other and substantially parallel with the pivot axis A.
  • the open end 17a of the second opening 17 allows the pre-loading pin 18 to at least partially exit the second opening 17, in a direction parallel with the longitudinal extent of the oblong first opening 9, if the load L applied by the sash 1 is reduced or reversed.
  • the releasable connection pin 8 extends in a direction substantially parallel with the pivot axis A, through the first opening 9 and through at least one of a fourth opening 10 in the sash side member 1a, 1b and a third opening 11 in the suspension arm 3. As the releasable connection pin 8 connects the bracket 6 to the side sash member 1a, 1b and/or the suspension arm 3, the first pin end 8a is arranged closer to the center C of the sash than the second pin end 8b.
  • the actuator further comprises locking means 12 engaging the connection pin 8, the locking means 12 being configured for preventing the connection pin 8 from being removed from the oblong first opening 9.
  • the locking means 12, shown in Figs. 4b and 4c engage the first pin end 8a such that the releasable connection pin 8 is prevented from being removed from the fourth opening 10 and/or the third opening 11.
  • the locking means 12 comprises at least one of a threaded nut, a spring, a clip, a slider, and a pin.
  • the first pin end 8a is configured for engaging the locking means 12 by means of a section having a reduced diameter arranged at the first pin end 8a, as shown in Fig. 3c , or, as in a further embodiment, by means of a throughgoing channel 14 which extends perpendicular to the center axis CA of the releasable connection pin 8, and which receives a part of the locking means 12 such as, e.g., one leg of a spring as shown in Fig. 4b .
  • the releasable connection pin 8 extends through the fourth opening 10 of the sash side member 1a, 1b, and the first pin end 8a and the locking means 12 are arranged in a recess within the sash side member 1a, 1b.

  • the roof window is a center-pivoted roof window or a top-hung roof window comprising two actuators 4, each actuator 4 being arranged adjacent one frame side member 2a, 2b.
  • the present roof window has several benefits. For example, it enables large opening angles. Another benefit is having a large load capacity which remains stable with changing roof angles and during high load conditions (any push-pull situations which occur). A further benefit is that the push-pull chains can be placed substantially out of sight at the sides of the window, allowing the window to have a slenderer appearance and providing a better view. Additionally, the need for window load balancing by springs is reduced, such that the springs do not need adjustment or may be entirely omitted. Another benefit is that the push-pull chain actuator may keep the window closed without additional need for a window lock. Furthermore, the window installation process and the process of connecting the push-pull chain(s) is enhanced. Finally, the push-pull chain is burglar protected while still enabling service of the window.
