Definitions

  • the present invention relates to a screening arrangement for a window, preferably a roof window, comprising a frame with a top member, a bottom member and two side members, the screening arrangement comprising: at least one bottom element, and two side rails defining a longitudinal direction, a width direction and a depth direction, the at least one bottom element being movable with respect to the two side rails between a non-screening position and a screening position by means of a drive means comprising a first transmission means comprising a circular gear including at least one pinion arranged in said at least one bottom element, and a second transmission means comprising two racks of teeth arranged in each of the two side rails such as to extend substantially in the longitudinal direction of the side rail, to engage with the at least one pinion of the first transmission means, each side rail comprising a first flange extending substantially in the width direction, a second flange extending substantially in parallel with the first flange, in the width direction, and positioned to cover at least a part of the bottom element, and
  • Screening arrangements including screening devices in the form of blinds are traditionally used for screening an aperture of a building structure, most often the light-admitting aperture of windows, but also of doors and other building openings.
  • the blinds are either installed to extend substantially vertically in a building façade, or in an obliquely positioned roof window installed in an inclined surface, or as a horizontally extending cover for openings in a horizontal surface.
  • the screening body is normally rolled or folded up and gathered at a top element of the screening arrangement.
  • Examples of prior art screening arrangements include Applicant's European patents EP2738342 B1 , EP2738343 B1 and EP2738344 B1 .
  • the operational principles of such screening arrangements are based on well-proven techniques known for instance from GB 668669 , US 8,881,790 B2 and DE 202007018180 U1 .
  • the side rails of such screening arrangements thus function partly as guiding means for guiding the bottom element and side edges of the screening body of the screening arrangement during operation, partly additional darkening in the case of black-out blinds. Furthermore, the side rails function to cover drive means which in some applications include cord systems and pulleys. Eventually, the side rails need to provide an aesthetically pleasing transition between the screening arrangement and the surrounding building structure, typically an inner wall.
  • the side rails are slender and of a thin-walled material. Since a number of functionalities are necessarily included in the side rails, which at the same time must fulfil certain requirements to appearance, the available space is unavoidably limited.
  • a screening arrangement which is characterised in that said second transmission means is formed integrally in at least one of said flanges of said side rail, and said side rail is of an extrudable material, wherein the second transmission means comprising the at least two racks of teeth to engage with the at least one pinion of the first transmission means, and wherein the teeth of said racks have a base portion provided at the at least one flange, a head portion engaging the first transmission means, and a body portion extending between the base portion and the head portion, and wherein said at least two racks are formed integrally in the same flange, and said at least two racks being preferably substantially parallel with each other, and wherein said pinion is provided with such a width that the at least one pinion extends across and is configured to mesh with at least a part of each of the two parallel racks of teeth.
  • the drive means is rendered substantially more compact while at the same time providing the required operational conditions.
  • Forming the second transmission means in one or more of the flanges already present in the side rail an optimum balance is found in that the side rail is easily mounted on the frame of the window, whereas it is at the same time possible to choose the location of the second transmission means in a flexible way.
  • the rack-and-pinion transmission may be formed in an optimum manner by a careful choice of dimensions of the portions of the rack of teeth.
  • extruable material should be interpreted to incorporate any material that is able to be formed by forcing a blank of material through a die of a desired cross-section.
  • Typical extrudable materials include metallic and plastic materials, but also composite, ceramic and fiber materials are conceivable.
  • the term "drive means" should be interpreted in its broadest sense, encompassing all kinds of force and movement transmission between the first transmission means and the second transmission means.
  • the first transmission means transmits a driving force to the second transmission means whereby the bottom element is moved.
  • the driving force is provided by the user pushing or pulling the bottom element whereby the interaction between the first and second transmission means provides guidance and synchronicity such that the ends of the bottom element move at the same pace. In this way, the bottom element is kept parallel to the top and bottom members of the frame at all times, thereby avoiding skew positions that could hamper proper functioning.
  • electrically operated screening arrangement only one end of the bottom element needs to be provided with driven first transmission means whereas the first transmission means at the other end acts as a follower.
  • the shape and relative dimensions of the head portion of the rack of teeth may be chosen to fit the required specifications and in dependence on the choice of material, both of the side rail with the integrated rack of teeth and of the pinion.
  • the formation of the teeth of the rack or racks may in principle be carried out in any suitable manner.
  • the at least one rack of teeth is formed by extrusion and at least one subsequent rack forming operation, where the head portion is preferably provided with a larger extent in the width direction during the subsequent rack forming operation.
  • Fig. 1 shows a prior art screening arrangement 3' installed in a window generally designated 1, here represented by a frame 2 which is an openable sash adapted to be mounted in a stationary frame (not shown), for instance to be installed in an inclined roof surface.
  • a frame 2 which is an openable sash adapted to be mounted in a stationary frame (not shown), for instance to be installed in an inclined roof surface.
  • the terms "sash” or "frame” are to be understood as incorporating any substantially rectangular structure positioned in any opening in a building, whether in a wall or the roof, and surrounding an aperture to be screened.
  • the frame 2 thus has four frame members: a top member, a bottom member and two side members.
  • the frame 2 is thus a glass-carrying sash encasing a pane 5 in the opening formed by the frame members.
  • Such a prior art screening arrangement is shown and described in for instance Applicant's European patent EP2150671 B1 .
  • the prior art screening arrangement 3' defines, in the condition of use in which it is mounted in the frame 2, a screening plane substantially parallel to a plane defined the longitudinal extensions of the top and bottom members of the frame on one hand and the longitudinal direction of the side members on the other.
  • the terms “left-hand” and “right-hand” refer to the orientation shown in for instance Fig. 1 , and are utilized for reasons of convenience only.
  • the terms “front” and “back” are utilized to denote the sides of the screening arrangement 3', “front” being the side intended to face inwards into the interior of a building, and “back” the outwards facing side.
  • the terms “upper” and “lower” refer to the orientation of the screening arrangement installed in a frame, where “upper” refers to the top member of the frame and “lower” refers to the bottom member of the frame.
  • the prior art screening arrangement 3' has a bottom element 4' connected to a screening body (not shown) which extends in the screening plane and covers the opening of the frame in its screening positions, whereas it is placed in its non-screening position at the top member of the frame 2 in Fig. 1 .
  • the side edges of the screening body and the longitudinal ends of the bottom element 4' are guided in side rails 10' connected to the side members of the frame 2.
  • the side rails 10' are mitred at one end and connected to a top rail.
  • the orientation and terms used to describe the screening arrangement in the present context are for convenience and ease of understanding; hence, the bottom element could thus be provided in parallel with "side” members instead, depending on the specific orientation in the mounted condition.
  • the screening arrangement 3 comprises a bottom element 4 (cf. Fig. 4 ) and two side rails 10 of which one is shown. It is to be understood that more than one bottom element 4 may be present in the case of more than one screening device is present, and the term bottom element is also intended to cover any movable profile or bar element fulfilling the function. It is also to be understood that although only one side rail 10 is shown, the other side rail to be positioned at the opposite side member may be formed in the same manner, mirror inverted, or be of a varied design.
  • the side rail 10 is seen from the back side of the screening arrangement and defines a longitudinal direction L, a width direction W and a depth direction D.
  • the bottom element 4 is movable with respect to the two side rails 10 between a non-screening position and a screening position by means of a drive means comprising a first transmission means generally designated 30 arranged in the bottom element 4, and a second transmission means generally designated 20 arranged in each of the two side rails 10 such as to extend substantially in the longitudinal direction L of the side rail 10.
  • the second transmission means 20 is formed integrally in said side rail 10, and the side rail 10 is of a metallic material.
  • the side rail 10 comprises a first flange 11 extending substantially in the width direction W, a second flange 12 extending substantially in the width direction W and positioned to cover at least a part of the bottom element 4, and a third flange 13 connecting the first and second flanges 11, 12 and extending substantially in the depth direction D.
  • the second flange 12 faces the interior of the room and thus forms a front surface of the side rail 10 in the mounted condition of the screening arrangement.
  • the third flange 13 of this embodiment has an extended portion 14 extending from the first flange 11 in the depth direction D away from the second flange 12.
  • Fastening means such as openings for the reception of screws or the like, or snap engagement means are present in the side rail 10 to allow connection to the respective side member of the frame of the window.
  • the fastening means are typically provided in the third flange 13, and/or in the specific embodiment, in the extended portion 14 of the third flange 13.
  • the side rail 10 is provided with further flanges including a fourth flange 15 at the end of the first flange 11 opposite its connection to the third flange 13.
  • the fourth flange 15 has an extended portion 16 forming together with a fifth flange 18 provided on the second flange 12 an opening extending throughout the longitudinal direction L of the side rail 10 to receive a side edge of the screening body.
  • the fifth flange 18 also forms a track together with a sixth flange 19a protruding from the third flange 13. This track serves to receive an angular bracket to form a mitred connection with a top rail as mentioned in the above description of the prior art screening arrangement.
  • the side rail 10 may be provided with a seventh flange 19b located opposite the above-mentioned opening between the extended portion 16 of the fourth flange 15 and the fifth flange 18.
  • the seventh flange 19b functions as an end stop for the side edges of the screening body and guide elements (not shown) at the ends of the bottom element 4. This ensures that the screening body and the bottom element 4 are kept in position, and in turn secures the engagement between the first and second transmission means.
  • Such an end stop, or end guide could alternatively or additionally be provided in any other suitable manner; for instance by meshing gears etc.
  • One example of a guide is for instance given in Applicant's published European patent application EP 2 476 858 A2 .
  • the second transmission means 20 could be formed in any flange of the side rail 10 to obtain maximum flexibility as regards the position.
  • the transmission means may be placed in one of the first, second and third flanges 11, 12, and 13. It is also conceivable to form second transmission means 20 in more than one flange.
  • the second transmission means 20 is formed in one flange only, and in particular as here in the first flange 11.
  • the second transmission means is formed in the second flange 12.
  • a further alternative embodiment showing the position in the third flange 13 is shown in Fig. 12a .
  • the transmission means 20 may alternatively be formed in the fourth flange 15 as shown in Fig. 12c .
  • the second transmission means of the side rail 10 of the screening arrangement 3 comprises at least one rack of teeth 20 to engage with the first transmission means 30 of the bottom element 4.
  • the rack 20 is thus formed integrally in the side rail 10.
  • the rack 20 is formed in the first flange 11 to protrude in the depth direction D, away from the second flange 12.
  • the formation of the rack 20 facing outwards as in Figs 2 to 4 is of particular advantage in roof windows which are traditionally installed in an inclined position. Hence, gravity will ensure a safe engagement between the first transmission means 30 and the second transmission means, here in the form of rack 20.
  • An alternative position, although not preferred, is shown in Fig. 12b .
  • the rack of teeth incorporates forming the rack of teeth as an integral structure protruding from the actual flange of the side rail.
  • the rack of teeth may thus be said to form a rack flange protruding from the side rail flange, and in which the teeth are formed, thus rendering the rack flange including its teeth as a comb-like structure.
  • the profiling of the rack of teeth 20 of the second transmission means is chosen to fit the requirements to the screening arrangement in question.
  • the teeth of the rack 20 have a base portion 23 provided at the first flange 11, a head portion 21 engaging the first transmission means 30, and a body portion 22 extending between the base portion 23 and the head portion 21.
  • the head portion 21 of the rack of teeth 20 is wider, i.e. has a larger extent in the width direction W, than at least the part of the body portion 22 of the rack which is adjacent to the head portion 21.
  • the difference in width between the head portion 21 and the body portion 22 is advantageous in that a more secure engagement between the first transmission means 30 and the second transmission means, here in the form of rack 20, is ensured.
  • Typical values of the ratio between the width of the head portion 21 and the width of the body portion 22 at the part adjacent to the head portion include a range of at least 1.05:1: preferably at least 1.2:1, and more preferably at least 2:1.
  • the shape of the head portion 21 of the rack of teeth 20 may in principle be formed in any suitable manner as long as it may be warranted from a manufacture point of view.
  • the head portion 21 is substantially bud-shaped.
  • Alternative shapes may advantageously be selected from the group comprising: substantially circular, anvil-shaped, and T-shaped. Examples of such alternative shapes are shown in Figs 5f, Fig. 5e and Fig. 5g , respectively.
  • the head portion 21 may be formed wider than the body portion 22 already during the initial forming step, typically during extrusion, or the head portion 21 and the body portion 22 may be formed with similar width and the head portion 21 made wider during a subsequent step.
  • the rack of teeth 20 is formed by extrusion and one or more subsequent rack forming operations.
  • the head portion may be provided with a wider extent. This applies both when the side rail is extruded with a rack flange as a precursor to the rack of teeth in which the head portion already has a larger width than the body portion and/or the base portion, and when the side rail following extrusion is provided with a shape of the rack flange to form the rack of teeth 20, as shown for instance in Figs 5a-5d and 5h .
  • the teeth of the rack 20 including the head portion 21 and entire body portion 22 are also conceivable.
  • the teeth of the rack 20 may be curved (not shown). In such a curved configuration, it is possible to provide the screening arrangement with an outwards directed force acting to keep the first and second transmission means in mutual engagement and at the same time ensure that the screening body is kept tight.
  • a tapered shape in the depth direction D is also conceivable, preferably also including the body portion 22 ( Figs 5c and 5d ).
  • the teeth of the rack 20 may be substantially straight, optionally perpendicular to the sides of the head portion 21 ( Figs 5a, 5b and 5h ).
  • One further aspect to the formation of the side rail 10 with integral second transmission means 20 is the strength and mechanical properties such as bending resistance. This applies to the side rail in general and in the above embodiments to the flange in which the rack of teeth 20 is formed in particular. Hence, a support portion 17 may be present opposite the base portion 23.
  • the ratio between the width, i.e. the dimension in the width direction W, of the head portion and the height, i.e. the dimension in the depth direction D, of the rack, from the base portion to the head portion, is up to 1:3, preferably up to 1:4.
  • two parallel racks 20a, 20b are formed integrally in the same flange 11. Further racks may be provided in the same flange, or a further rack may be provided in another flange than the first.
  • the pinion 31 is provided with such a width that the pinion 3 extends across and is configured to mesh with at least a part of each of the two parallel racks of teeth 20a, 20b. More specific, the pinion 31 shown in Fig. 7 has a width to substantially cover the racks of teeth 20a, 20b.

  • the width of the two pinions may be identical or different from each other.
  • the screening arrangement is provided with two racks of teeth 20a, 20b to engage with at least one pinion 31.

  • the pinion 31 is provided with such a width that it extends across and is configured to mesh with at least a part of each of the two parallel racks of teeth 20a, 20b.
  • the provision of two racks of teeth 20a, 20b entails that a stable engagement between the first and second transmission means is obtained, regardless of the profiling of the racks of teeth.
  • the head portion of the respective rack of teeth may be made wider than at least the portion of the body portion adjacent to the head portion.
  • the first transmission means 30 needs to be configured to allow proper transmission of forces and movements.
