Definitions

  • the present invention relates to an actuator for moving an object from one position to a second position and vice versa and if desired any position therebetween.
  • actuators are used to control the position of a window sash such as in bottom-hung, tophung or side-hung windows, sky lights and of doors such as ventilation doors.
  • Conventional actuators of this type as known from e.g. AU B1-51 808/79 use a chain, i.e. a chain storable within a housing and with the chain being extended from and retracted into the housing by means of a rotatable drive sprocket having a toothed relation with the chain.
  • a chain i.e. a chain storable within a housing and with the chain being extended from and retracted into the housing by means of a rotatable drive sprocket having a toothed relation with the chain.
  • EP-B-0 708 218 discloses a chain actuator with a spindle drive.
  • the housing of the actuator is provided with separate guide channels for the nut of the spindle and for the chain.
  • the two channels are separated by a wall provided with a longitudinal slit through which a foot of the nut protrudes to engage the inner end of the chain.
  • the cross-sectional area of the housing is about ten times the cross-sectional area of chain.
  • these actuators are either mounted on top of the master window frame or window sash, or alternatively, they are build in the master window frame or window sash after a space has been machined in either of these window parts. By machining such a space, the stiffness/stability of the profile in question, and consequently, the stability of the window frame as such is sometimes significantly reduced.
  • a window sash or a window frame usually consists of an inner frame build up of extruded profiles and an outer frame build up of extruded profiles.
  • the inner frame and the outer frame are separated by an insulation frame. Machining a space for the prior art actuators usually results in removing locally the insulation frame, thus creating a thermal break between the inner and outer frames reducing the insulation capacity of the overall window significantly.

  • the cross-section of the frame 30 is substantially equal to the inside of the housing 20, so that the frame 30 is retained in the housing 20 in a stable manner.
  • the frame 30 is a machined part, preferably made of aluminum, and defines an outer curved guide 34 with a guide surface in the form of an arc that extends over an angle of 90° for guiding the chain 12 towards the chain exit aperture 21.
  • the frame 30 is further provided with a transversely extending guide channel 36 for an exit guide 70.
  • the frame 30 further comprises a bridge 37 spanning between the first extremity 33 and a second extremity 38 of the frame 30. Between the opposite ends of the bridge 37, two parallel slits 43,44 facing one another are provided for receiving a print board 50 with the electric control of the actuator 1.
  • the second extremity 38 is provided with a cylindrical aperture 39 for receiving an output shaft 61 of a planetary reduction gear 60.
  • the reduction gear 60 is driven by a DC motor 62.
  • the DC motor 62 and its output shaft (not shown) are concentrically located inside the housing 20.
  • the planetary reduction gear 60, and its output 61 shaft are also concentrically located within the housing 20.
  • the spindle 27 is however not located concentrically in the housing 20.
  • the output 61 shaft is therefore connected to the spindle 27 by a double universal joint 66 extending between the opposite extremities 33,38 of the frame 30.
  • a movable exit guide 70 is provided in the transversely extending guide channel 36 adjacent the chain exit aperture 21.
  • the exit guide 70 is provided with a chain guide surface 71 extending substantially perpendicular to the longitudinal axis of the housing 20 for ensuring that the chain 12 leaves the housing 20 as a substantially straight and rigid member.

This additional transverse guidance is advantageous because the extend of the transversely extending guide channel 36 at the side facing the outer curved guide 34 is relatively short.
  • a box shaped nut 80 is in treaded engagement with the thread of the spindle 27.
  • the nut 80 has a rectangular cross-section (in a plane perpendicular to the spindle 27 axis), with a lesser extension and a larger extension. The larger extension is somewhat smaller that the corresponding inside width of the housing 20.

  • the strips 92,93 rest with their rear surfaces on the inner surface of the housing 20.
  • the thickness of the strips 92,93 is such that the distance between the first- and second guide surfaces 90,91 is substantially equal to the chain width, which is in turn substantially equal to the lesser extension of the nut 80.

  • the linear drive means may be formed by a hydraulic or pneumatic cylinder (not shown). It is also possible to use a tooth belt (not shown) provided with teeth on both sides of the belt. The belt extends along a part of the length of the chain, whereby the teeth on the outer side of the belt are in engagement with the chain.
  • the invention as described here allows the construction of an actuator with a ratio between cross-sectional surface of the chain and the cross-sectional surface of the housing which is improved by about a factor two.
  • the actuator according to the invention is therefore substantially more compact than any of the prior art actuators, and can consequently, be mounted inside window profiles without machined additional space into such a window profile.
