Definitions

  • the present invention relates to an electrical window opener for opening and closing a window that is hinged to a window frame. More particularly the invention relates to an electrical window opener having a chain actuator.
  • Electrical window openers are used for various solutions including domestic applications, in which windows that are hinged to a window frame are required to be automatically opened and closed.
  • the typical electrical window opener for opening and closing windows that are hinged to a window frame comprises a large housing configured to be rotatably attached to a window frame by means of two frame brackets attached in each end of the housing. The pivot axis of each frame bracket normally extends parallel to the longitudinal axis of the housing.
  • These prior art window openers typically comprise a moveably arranged chain extending between an attachment point inside the housing and a window bracket attached to the window.
  • An electric motor mounted inside the housing is configured to open and close the window by rolling or pushing in and out the chain whereby the distance between the cabinet/housing of the window opener and the window bracket is changed.
  • the cabinet/housing of a prior art window opener is, however, often very large. Therefore, the housing is typically too large or difficult to build into a window frame. Since the distance between the attachment point of the chain inside the housing and the attachment point of the frame brackets is rather large, the force arm and thus the bending moment (the internal reaction of the housing to the bending load caused by the chain force) is large. Therefore, the prior art housings are required to be strong and stiff.
  • the opening device for opening and closing a window sash relative to a fixed frame.
  • the opening device comprises an electrically operable drive unit that is integrated in the frame and - one on a profile of the window sash arranged bearing block.
  • the drive unit being connected to the bearing block via a coupling member movable by the drive unit.
  • the bearing block is connected to at least one locking means is locked on the window sash.
  • the locking means is accessible in a closed position of the window sash through an unlocking opening provided in the profile of the window sash.
  • the opening device includes a bracket mounted inside the motor. This bracket is for fixed mounting. Accordingly, it would be desirable to have an opening device allowing the motor to be rotated relative to the frame.
  • DE102016000568 A1 discloses a window opener, which comprises a housing that can rotate. However, due to its construction it is not possible to attach the opener to smaller windows.

  • the bending moment (the internal reaction of the housing to the bending load caused by the chain force) is much smaller.
  • the strength and stiffness of the housing can be reduced due to the smaller bending moment.
  • the housing may be produced in a less stiff material such as plastic.
  • the housing comprises an upper portion and a lower portion attached thereto.
  • the upper portion is detachably attached to the lower portion e.g. by means of any suitable mechanical attachment means such as corresponding male and female connection elements (including screws).

  • the electrical motor is a direct current (DC) motor.
  • the motor comprises or is connected to a shaft being at least partly made in a flexible material such as rubber or plastic.

  • each mounting structure comprises a plate-shaped portion configured to be attached to a corresponding protruding member of the frame bracket.
  • the attachment of the plate-shaped portion to the corresponding protruding member of the frame bracket can be accomplished by means of a screw inserted into a hole provided in the plate-shaped portion of the mounting structure and screwing the screw into a corresponding structure (e.g. threaded structure) in the protruding member.
  • the housing comprises a gear assembly comprising a series of engaging gear structures, wherein the first mounting structures is provided between the attachment of the chain and the gear assembly.

  • the additional module is a battery module.
  • a battery module makes it possible to reduce the capacity and size of the power supply compared with the ones found in the prior art. Since the batteries are charged when the motor is not active, the battery module constitutes a power source that can be used to add power to the power provided by the power supply when the motor is active and thus power consuming. Since the power supply is required to deliver a smaller power, it is possible to user electrical cables that are thinner than in the prior art window openers.

  • the window opener may comprise several motor modules in case a large force is needed to open and lock the window. Due to the small size of the housing of the window opener, the invention enables an easier integration of the window opener into a window frame. It may be an advantage to have another structure (e.g. a window sash) comprising a built-in electrical window opener according to the invention.

  • the housing 104 of the prior art window opener 102 is very large and this not fit for being build into a window frame. Moreover, due to the long force arm (the distance between the attachment point of the chain 8 inside the housing 104 and the attachment point of the frame brackets 106) the bending moment (the internal reaction of the housing 104 to the bending load caused by the chain force) is rather large.
