Definitions

  • the present invention relates to a screening arrangement for a window, preferably a roof window, said window comprising a frame with a top member, a bottom member and two mutually parallel side members, said screening arrangement comprising a screening body having two side edges and a top and bottom portion, two side rails, each extending in a longitudinal direction, a width direction and a depth direction, each side rail being configured to be connected to a respective side member of the frame in a mounted condition of the screening arrangement, a top casing accommodating at least the top portion of the screening body and configured to be connected to the top member of the frame and to an upper end of the respective side rail in the mounted condition of the screening arrangement, the top casing being composed by at least one longitudinal profile extending in a direction parallel to the width direction in the mounted condition, and two end pieces connected to respective longitudinal ends of the top casing, a bottom element connected to the bottom portion of the screening body and being configured to be longitudinally positionable in said longitudinal direction between a non-screening position of the screening body and a screening position by means of
  • each end piece of the top casing is provided with a rack segment configured to be adjoined with the rack of the respective side rail in the mounted condition of the screening arrangement so as to form a continuous rack path for the cogwheel of the first transmission means.
  • the suspension elements present in the prior art arrangements may be dispensed with. This provides for a facilitated assembly operation already at the factory side, since the step of setting the suspension elements in the correct position is rendered superfluous.
  • the user simply mounts the top casing including end pieces and respective rack segments in a first step, while the continuous rack path necessary to allow coherent engagement of the first and second transmission means is obtained in the subsequent mounting of the side rails including their respective rack.
  • the cogwheels of the first transmission means are thus prepared for engagement with the rack segments and the racks of the second transmission means such that screening arrangement is ready for use.
  • the rack segment of each end piece has a top end and a bottom end, the distance between the top and bottom ends defining a length of the rack segment in the longitudinal direction, the length being such that the cogwheel of the first transmission means is in engagement with the rack segment in a supply condition of the screening arrangement.
  • the rack segment has at least such a length that it extends at least to the lowermost point of the cogwheel, as seen in the depth direction.
  • the length of the rack segment of each end piece substantially corresponds to a height of the bottom element as seen in the longitudinal direction.
  • this configuration contributes to the compact appearance of the screening arrangement in the supply condition and also to some extent provides protection of the rack segment.
  • the top end of the rack segment of each end piece is positioned at a transition portion formed at a lower edge of the end piece.
  • each end piece comprises a body portion which is substantially plane and parallel to a plane spanned by the length direction and the depth direction, and wherein a top resilient arm and a bottom flange form engagement means configured to interact with a mounting bracket connected with the associated side member of the frame of the roof window in the mounted condition of the screening arrangement.
  • the rack segment is formed integrally with the respective end piece. This may be carried out by moulding the end piece in one piece with the rack segment. The end pieces with integrated rack segments may then be connected to the remaining components of the top casing, thus ensuring a supply condition which is particularly easily obtained when assembling the screening arrangement.
  • each end piece may comprise a first connection portion extending from the body portion, optionally also a second and a third connection portion.
  • the connection portions may extend substantially perpendicularly to the body portion.
  • suitable engagement means may be provided to receive the connection portion(s).
  • an abutment portion is formed protruding from the body portion, and wherein the transition portion, if present, is formed in conjunction with said abutment portion. This configuration contributes to the structural integrity of the end piece.
  • the top casing comprises a front rail, a top cover portion, and a back cover portion. In this way, a reliable connection of the end piece to the top casing is ensured.
  • the top casing may be composed by a set of profiles defining a cross-sectional shape of the top casing, which ensures flexible design and manufacture of the screening arrangement.
  • a first profile comprises the front rail, the cover top portion and the cover back portion
  • a second profile comprises an additional back element adjoining the cover back portion.
  • the bottom element comprises a main portion composed by a set of profiles defining a cross-sectional shape of the bottom element, and two end portions surrounding respective longitudinal ends of the main portion of the bottom element.
  • flexibility and modularity are improved by the provision of a rack in each side rail which is composed by a plurality of rack segments adjoined with each other in the mounted condition of the screening arrangement so as to form a continuous rack path for the cogwheel of the first transmission means together with the rack segment of the associated end piece.
  • each side rail comprises a first flange forming a front of the side rail, and a leg extending at substantially right angles to the first flange and by which the side rail is configured to be connected to the respective side member of the frame, wherein a second flange protrudes from the leg at a distance from the first flange as seen in the depth direction, and wherein the rack of the side rail is provided on an underside of the second flange.
  • the first flange is longer than the second flange so as to accommodate the rack segment of the associated end piece in the mounted condition of the screening arrangement. This provides for optimum ease of installation and accommodation of the rack segment of the end piece.
  • the rack of the side rail may extend up to a predefined point on the underside of the second flange of the side rail to accommodate the rack segment on an upper portion of the underside of the second flange.
  • this configuration also provides reliable support of the rack segment in the mounted condition of the screening arrangement.
  • the screening arrangement may be operated either electrically or manually, in which case the transmission means ensure proper guidance of the bottom element in the side rails.
  • the drive means operably connecting the bottom element and the side rails are electric drive means, and the electric drive means comprise an electric motor located in the bottom element or in the top casing, and the operating means of the electric drive means accommodated in the bottom element comprise a rotatable shaft connected with the first transmission means, and wherein the electric drive means is powered by solar panels and/or mains power, preferably supplemented by battery means.
