Definitions

  • the present invention relates to a roof window according to the preamble of claim 1.
  • EP1681399A2 discloses a roof window according to the preamble of claim 1.
  • the striking bead coverings are traditionally formed as U-shaped profiles, a first wall of which protrudes into the glass rim profile. Water and other precipitation is led in the glass rim profile and out at the bottom of the window. However, wind may cause water to move inwards into the structure thus causing water penetration.
  • a labyrinth seal thus protects the interior of the window and provides the improved security aimed at.
  • the hinges used are preferably of the type described in the applicant's earlier patent applications WO9928581 and GB1028251 , where a curved member and a tap on one hinge part travels in a curved guide track in the other during opening and closing of the window.
  • the radius of curvature entails that when using such hinges, the hinge axis lies at a small distance above the actual hinge parts and as the sash frame is turned first the curved member and then the tap comes out of the track. In combination this provides a pattern of movement which allows easy operation of a centre-hung window and allows the sash frame to be turned substantially entirely around.
  • a closed position of the window 1 means a position in which the frame plane and the sash plane coincide, that is form an angle of 0 degrees with each other.
  • an open position of the window 1 as used herein generally means a position in which the sash 3 is tilted about the pivot hinge axis 21 such that the frame plane and the sash plane no longer coincide.
  • a longitudinal axis 13 of the window 1 is defined as extending perpendicular to and between the frame top member 5 and the frame bottom member 6
  • a transversal axis 14 of the window is defined as extending perpendicular to and between the respective frame side members 7 and 8 and thereby perpendicular to the longitudinal axis 13
  • a depth axis 15 of the window 1 is defined as extending perpendicular to both the longitudinal axis 13 and the transversal axis 14.
  • the pivot hinge axis 21 and the transversal axis 14 are parallel, and are shown as coinciding in the figures.
  • the window 1 furthermore comprises a lock 17 of a type known per se for locking the frame 2 and sash 3 to each other as well as a generally circumferentially extending sealing 18 provided on the sash 3 for sealing the gap between the sash 3 and the frame 2 in the closed position of the window 1.
  • the sealing 18 comprises at least one, preferably at least two sealing strips.
  • the window according to the invention may in other embodiments be top-hung, with or without an intermediate frame structure, have the hinge axis somewhere between the top and the centre, be side-hung or for that matter even be bottom-hung.
  • the sash 3 and frame 2 of the window according to the invention may for example be made of wooden members or members made of cast or extruded polyurethane (PUR).
  • PUR polyurethane
  • the window 1 comprises, at the bottom sash member 10 of the sash 3, at least one, preferably at least two, pane holding devices 300 for holding the pane 4 such as to keep it from falling out of the sash 3 of the window.
  • the pane holding device 300 is attached to a surface 307 of a bottom sash covering 319, and is shaped in such a way that it has a face 302 adapted for abutment with the pane 4.
  • the pane holding device 300 may for instance be substantially box shaped or substantially wedge-shaped.

  • an insulating element 303 for providing insulation of the transition between the bottom sash member 10 and the bottom sash covering 319.
  • the insulating element 303 comprises at least one, preferably at least two, recesses 304 shaped such as to be adapted to accommodate a pane holding device 300.

  • a locking mechanism 535 is mounted on each side frame member 7 and 8, e.g. by bringing the engagement means 562 and 563 into engagement with corresponding holes in the side frame members 7 and 8. Then the frame striking bead covering 217 is mounted such that the notch 229 is brought into engagement with the incisions 542a and 542b. Next, the top casing is put in place by bringing the respective guiding structures 547 and 548 into abutment. Finally an attachment means 536, such as a screw, is inserted into and through the hole 541 and further into the hole 551 in the structure 548 thereby securing the top casing 500 to the locking mechanism 535 and thereby to the frame 2 of the window 1.

This, in turn, prevents that precipitation is directed to the pane, which may be undesirable for several reasons.
  • the dimension of the mid portion 218 is sufficient to span the distance between the glass rim profile 102 to the gasket 261, but is in general kept as limited as possible. This is partly due to aesthetical but also practical considerations. By forming an extended portion of the covering in the manner described, a satisfactory balance has been found between these considerations, while simultaneously ensuring that precipitation is led to the glass rim profile rather than onto the pane.
  • a top edge 228 is provided with a substantially rectangular notch 229 as is best seen in Fig. 14 .
  • the side edges 230 and 231 of the notch 229 are configured to mate with incisions 542a, 542b provided in side faces of the structure 542 provided on the top casing locking mechanism 535.
  • the bottom edge 232 of the notch 229 is configured to abut an intermediate face 565 of the structure 542.
  • the notch 229 of the frame striking bead covering 217 is configured to slidingly engage the structure 542 and its incision 542a, 542b of the top casing locking mechanism 535 in order to be properly positioned during mounting.
  • the end 269 that is intended to be the lower end in a mounted condition has, as is best seen in Fig. 9 , a slope 280 towards a folded back portion 207 that serves as mounting means in relation to the bottom sash covering above glass 319.
  • the mounting means 207 which are best seen in Fig. 10 , and its cooperation with mating mounting means on the bottom sash covering above glass 319 takes place in a manner known per se and will therefore not be discussed in further detail here.
  • the end 268 that is intended to be the upper end in a mounted condition of the sash striking bead covering 201 is provided with a prolongation 281 of a part of the sash striking bead covering.
  • the prolongation 281 of the sash striking bead covering 201 causes a better draining of precipitation away from the sash structure.
  • the upper end 268, that is the end intended to be the upper end in a mounted condition of the sash striking bead covering 201, is provided with a corrugated section between a chamfer 234 and the upper side of the sash striking bead covering 201. This provides for a section which is able to lift precipitation that may have entered the space below the striking bead coverings up onto the outer surface of the sash striking bead covering 201.
  • the chamfer 234 When seen along a direction perpendicular to the longitudinal extension, the chamfer 234 extends at an angle different from 0° in relation to the remainder of the bottom edge 233, i.e. the bottom edge 233 of the mid portion 218 and the flange portions 219, 222 of the frame striking bead covering 217.
  • the angle 282 of the chamfer 234 in relation to the remainder of the bottom edge 233 is substantially 45°.
  • the chamfer 234 is adapted to avoid that the bottom edge 233 of the frame striking bead covering 217 comes into harmful contact with the upper end 268 of the sash striking bead covering 201 during opening and closing of window 1, so that grating and scratching of both the frame and sash striking bead covering 201, 217 is avoided.
  • the window 1 furthermore comprises a sash striking bead covering 201 as well as a frame striking bead covering 217.
  • the sash striking bead covering 201 as well as the frame striking bead covering 217 is provided with a male part 208 of a snap lock fastening means for fastening the sash or frame striking bead covering 201 or 217 to the sash 3 or the frame 2.
  • the male part 208 of the snap lock fastening means will be described with reference to the frame striking bead covering 217, but it is understood that the male part of the snap lock fastening means on the sash striking bead covering 201 is similar.
  • the male part 208 comprises a first leg 210 and a second leg 211, both of which extend from underneath and substantially perpendicular to the mid portion 218 of the frame striking bead covering 217.
  • the first leg 210 is shorter than the second leg 211 and preferably approximately 1/4-3/4 of the length of the second leg 211.
  • the first leg 210 is of a thickness that allows it to contain fastening means, preferably a pop rivet 212, for fastening the male part 208 to the frame striking bead covering 217.
  • the second leg 211 is flexible along a direction 283 perpendicular to its own longitudinal extension and towards and away from the first leg 210.
  • a protrusion 216 is provided on a face of the second leg 211 that faces away from the first leg 210.
  • the male part 208 is adapted to engage in a snap-locking way with a female part 209 of the snap lock fastening means.
  • a female part 209 is provided on the sash 3 and the frame 2, respectively, for the male part 208 on the sash and frame striking bead coverings, respectively.
  • the female part 209 that is adapted to receive the male part that is provided on the frame striking bead covering 217 is configured to be fastened to the frame part 20 of the pivot hinge.
  • the female part 209' that is adapted to receive the male part that is provided on the sash striking bead covering 201 is configured to be fastened to the sash part (not shown) of the pivot hinge 200. It is understood that the female parts 209 and 209' do not necessarily have to be fastened to the respective parts of the pivot hinge. It is envisaged that the female parts are fastened to the side sash member 11 and side frame member 7, respectively, directly.
  • the female part 209 indicated in Figs 14 and 15 is that adapted to engage with the frame striking bead covering 217 and is fastened on the side frame member 7.
  • the female part 209 of the snap lock fastening means has the general shape of an angle bracket.
  • One leg 213 thereof is adapted for fastening to a hinge part 19, 20 or side member 7, 11.
  • Another leg 214 thereof is provided with an opening 215 (as is seen in Fig. 14 ) configured to receive a male part 208 of the kind described above.
  • the hinge parts of the pivot hinge 200 may have elements that assist in forming the female parts 209 of the snap lock fastening means.
  • the female parts 209 of the snap lock fastening means may be integrally formed in the hinge parts.
  • the shape of the opening 215 is substantially such that the male part 208 is retained in the female part 209 once inserted. To this end, the flexibility and the protrusion 216 of the second leg 211 assist so that a snap locking effect is obtained.
  • the second leg 211 of the male part 208 is pressed towards the first leg 210 of the male part 208 until the protrusion 216 on the second leg 211 can pass through the opening 215 together with the rest of the male part 208. Now, the male part 208 can be retracted from the female part 209.
  • Fastening the striking bead covering with the above described snap-lock fastening means is advantageous over the prior art fastening by the aid of screws, since the fastening means are fastened to the striking bead coverings and does not get lost as easily as screws. Also, there are no through holes in the striking bead coverings for insertion of mounting screws. Hence, the risk of water intrusion into the frame and sash structure is reduced. Also, a nicer and more homogeneous appearance is obtained. Furthermore, this embodiment provides for a safer mounting in relation to break-ins, as there are no screws that are accessible from the outside. Furthermore, the snap lock engagement can only be released from the inside of a building in which the window 1 is mounted, as the protrusion 216 on the second leg 211 of the male part 208 is to be pressed from inside in order to release from engagement.
  • Both the male part 208 and female part 209 of the snap lock fastening means is made of POM.
  • Using a polymer is beneficial, as it has poor heat conductive properties. Hence, the risk of forming a thermal bridge is reduced.
  • POM has sufficiently high tensile strength to provide a secure and robust fastening of the striking bead coverings.
  • the male and female part of the snap lock fastening means can be made of any suitable material with a sufficiently high tensile strength.
  • the male part of the snap lock fastening means may be in the form of a leaf spring made from a suitably flexible and strong metal or alloy or combination thereof.
  • the female part may be made of any material adapted to suitably mate the leaf spring material as regards avoiding formation of a heat bridge and robustness.
  • the female part of the snap lock fastening means is provided on the sash and/or frame striking bead covering, while the male part of the snap lock fastening means is provided on the sash and/or frame.
  • a bottom frame covering 237 is provided. As is best seen in Figs 9 and 27, the bottom frame covering 237 is adapted to extend, in a mounted condition, with its longitudinal extension 249 along the longitudinal extension of the bottom frame member 6. The bottom frame covering 237 is configured to extend essentially along the entire length of the bottom frame member 6 so as to cover it from intrusion of precipitation.
  • the bottom frame covering 237 is essentially symmetrical around a plane perpendicular to its longitudinal extension 249. In the following, focus will be on the end 238 of bottom frame covering 237 that is adapted to cooperate with the one side frame member 7 and the elements cooperating with that end 238. It is understood, however, that the same considerations apply to the opposite end of the bottom frame covering 237 and those elements cooperating therewith.
  • the end region 238 of the bottom frame covering 237 is adapted to serve, via an intermediate member 245 that will be described in further detail below, as mount for an angle bracket 239.
  • the angle bracket 239 forms part of a fitting set adapted to be connected to the frame side member and to the side frame covering.
  • the angle bracket 239 has a longitudinal extension 240 and is adapted to extend, in a mounted condition, with its longitudinal extension 240 along the longitudinal extension of the side frame member 7. To this end, the side frame member 7 is provided with a recess (not shown in detail).
  • the angle bracket 239 comprises a first wall 241 and a second wall 242, the two walls being essentially perpendicular to each other.
  • An inner face of the first wall 241 of the angle bracket 239 is adapted to abut (directly and indirectly, as will be elaborated later) on an outer side face 7a of the side frame member 7. Also, the inner face of the first wall 241 abuts on an end edge 244 of the bottom frame covering 237 as well (not clearly discernible on any of the figures).
  • An inner face of the second wall 242 of the angle bracket 239 is adapted to abut (directly and indirectly) on an upper face 7b of the side frame member 7, possibly in the above-mentioned recess. Also, the inner face of the second wall 242 is adapted to abut (indirectly) an upward-facing face 274 of the bottom frame covering 237.
  • An outer face of the first wall 241 of the angle bracket 239 is adapted to abut an inner face of a first wall 272 of the side frame covering 270.
  • An outer face of the second wall 242 of the angle bracket 239 is adapted to abut an inner face of a second wall 273 of the side frame covering 270.
  • the walls 241, 242 extend into grooves 246 and 247, respectively.
  • the grooves 246, 247 are adapted to fit into mating folded-back portions 276, 277 of the first 272 and second 273 wall, respectively, of the side frame covering 270 (cf. Fig. 19 ).
  • the dimensions of the folded-back portions 276, 277 and the grooves 246, 247 are configured so as to effect a snap-locking engagement of the side frame covering 270 to the angle bracket 239. This eases the mounting process of the side frame covering 270 in that the mounting takes place without further mounting means such as screws.
  • the angle bracket 239 is nevertheless provided with a through hole 278 intended for passage of a screw for any subsequent mounting of optional equipment, such as shutters or other forms of sun screening.
  • the longitudinal extension 240 of the angle bracket 239 ensures a good guidance of the side frame covering 270 a stretch up along the side frame covering 270 in relation to the bottom frame covering 237 and in relation to the side frame member 7. In a mounted condition the result is increased stability and robustness of the corner between the bottom frame covering 237 and the side frame covering 270.
  • An intermediate element 245 (most clearly discernible on fig. 18 ) is provided and is adapted to be positioned at the end region 238 of the bottom frame covering 237. It is intended for being positioned between the angle bracket 239 and the side frame member 7 and the bottom frame covering 237, respectively.
  • a slit 248 is provided in the wall 250 of the intermediate member 245 that is configured to be parallel to the upper face 251 of the bottom frame covering 237 in a mounted condition.
  • the slit 248 is adapted to receive an essentially T-shaped protrusion 252 extending from the second wall 242 of the angle bracket 239 in a direction parallel to the first wall 241 of the angle bracket 239 (see Fig. 19 ).
  • the T-shape of the protrusion 252 is intended to function as a barb and retain the angle bracket 239 in the intermediate member 245 once inserted.
  • An L-shaped flange 253 protrudes from the wall 250 of the intermediate member 245 with its first wall 254 being essentially perpendicular to the wall 250 and its second wall 255 being essentially parallel to the wall 250.
  • the flange is adapted to sealingly abut its counterpart of the sash striking bead covering 201 in a mounted condition of both, when the sash 3 is closed against the frame 2.
  • the primary purpose of the intermediate member is to provide a water tight connection.
  • a guide member 256 is provided.
  • the guide member 256 is essentially hook shaped and is adapted to be fastened to the frame part 20 of the pivot hinge with its base part 257 and to grip around a flange 271 of the side frame covering 270 with its hook part 258. This further assists in providing a screw-less, yet robust, mounting of the side frame covering 270.
  • Figs 20-22 a slightly different embodiment of the window according to the invention is shown.
