[0001] The present invention relates to a roof window comprising a frame with a top member, a bottom member and two side members defining a frame plane, and a sash having a top member, a bottom member and two side members defining a sash plane, the roof window further comprising, in connection with the sash top member, a top sash module, the roof window furthermore comprising at least one barrel bolt adapted for releasably locking the sash to the frame in a position of the roof window in which the sash is rotated to a position outside its normal opening range, preferably close to 180 degrees, about a pivot hinge axis with respect to the frame, the barrel bolt comprising a housing and a bolt arranged in the housing in such a way as to be longitudinally displaceable in relation to the housing, the barrel bolt furthermore comprising an operating means. The present invention furthermore relates to such a barrel bolt. -
[0002] In known roof windows of this kind the operating means has been made as small as possible both for aesthetic reasons and in order to minimize the amount of material used when producing the barrel bolts. -
[0003] In types of windows having elements such as for instance a top sash module provided at the top sash member for ventilation purposes and arranged essentially outside the sash plane of the window, however, the known types of such barrel bolts have turned out to be very difficult to operate, as access to the barrel bolt is impeded. -
[0004] It is therefore an object of the present invention to provide in a first aspect of the invention a roof window, and in a second aspect of the invention a barrel bolt, which is more easily operated in all types of windows. -
[0005] In a first aspect of the invention, this and other objects are achieved with a roof window of the above kind, where the operating means has an angle with respect to the bolt such that it extends substantially in the direction of a depth axis of the window, and a length such that it terminates approximately level with the surface of the top sash module facing away from the housing of the barrel bolt. -
[0006] Thereby a roof window is provided with which the barrel bolt is easy and straightforward to reach and thereby to operate when the user desires to fix the window in a position allowing cleaning of the outside surface of the pane from the inside of a building. -
[0007] In a second aspect of the invention, this and other objects are achieved with a barrel bolt for releasably locking a sash of a roof window to a frame of the roof window in a position of the roof window in which the sash is rotated approximately to 180 degrees around a pivot hinge axis with respect to the frame, the barrel bolt comprising a housing and a bolt arranged in the housing in such a way as to be longitudinally displaceable in a telescopic manner within the housing, and an operating means, wherein the operating means of the barrel bolt extends at an angle, preferably at a right angle, with respect to the longitudinal direction of the bolt, and has a length of between 1 and 3 cm. The chosen angle and range of the length makes it possible to attain the easy operation aimed at while still providing for an aesthetically acceptable appearance. -
[0008] Preferred embodiments and further advantages will be apparent from the following detailed description and the appended dependent claims. -
[0009] The invention will be described in more detail below by means of a non-limiting example of an embodiment and with reference to the schematic drawing, in which -
Fig. 1 shows a perspective view of a window according to the invention in the assembled state seen from below or inside, -
Fig. 2 shows a perspective view of a window according to the invention in the assembled state seen from above or outside, -
Fig. 3 shows an exploded view of the top of a window according to the invention featuring a top sash module according to the invention, -
Fig. 4 shows an exploded view of the barrel bolt according toFig. 3 , -
Fig. 5 shows a close up view of the barrel bolt according toFig. 3 with the top sash module according toFig. 3 in the mounted position; -
Figs 6 and7 show views corresponding toFigs 1 and 2 showing a slightly different embodiment of the window according to the invention; and -
Fig. 8 shows a partial perspective view of the window shown inFigs 6 and7 . -
[0010] Fig. 1 and Fig. 2 show one embodiment of awindow 1 according to the invention comprising apane 4 defining plane 16, aframe 2 having atop member 5, abottom member 6 and twoside members sash 3 having atop member 9, abottom member 10 and twoside members sash 3 is connected to theframe 2 by a pivot hinge (not shown) provided betweenside members frame 2 andsash 3, respectively, to be openable by tilting thesash 3 of thewindow 1 about thepivot hinge axis 21 defined by the pivot hinge. The pivot hinge comprises two parts, namely a sash part and a frame part. -
[0011] The hinges used are preferably of the type described in the applicant's earlier patent applicationsWO9928581 GB1028251 -
[0012] As used in this description, a closed position of thewindow 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. Similarly an open position of thewindow 1 as used herein generally means a position in which thesash 3 is tilted about thepivot hinge axis 21 such that the frame plane and the sash plane no longer coincide. -
[0013] As seen inFig. 1 alongitudinal axis 13 of thewindow 1 is defined as extending perpendicular to and between the frametop member 5 and theframe bottom member 6, atransversal axis 14 of the window is defined as extending perpendicular to and between the respectiveframe side members longitudinal axis 13 and adepth axis 15 of thewindow 1 is defined as extending perpendicular to both thelongitudinal axis 13 and thetransversal axis 14. Thepivot hinge axis 21 and thetransversal axis 14 are parallel, and are shown as coinciding in the figures. -
[0014] Thewindow 1 furthermore comprises alock 17 of a type known per se for locking theframe 2 and sash 3 together as well as a generally circumferentially extending sealing 18 provided on thesash 3 for sealing the gap between thesash 3 and theframe 2 in the closed position of thewindow 1. The sealing 18 comprises at least one, preferably at least two sealing strips. -
[0015] Notwithstanding the centre-hung window 1 shown inFig. 1 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. -
[0016] -
[0017] Referring now toFig. 3 thewindow 1 comprises in connection with thetop member 9 of the sash 3 atop sash module 411 and aventilation flap 400. Thetop sash module 411 has a substantially rectangular cross section with afirst side 412, asecond side 415 opposite to and extending parallel with saidfirst side 411, athird side 413 and afourth side 414 opposite to and extending parallel with saidthird side 413. The third andfourth sides second sides -
[0018] Thefirst side 412 of thetop sash module 411 is adapted to be attached to or abutting a surface of the topsash member 9 opposite thepane 4 of thewindow 1. -
[0019] Theside sash members window 1 each comprise anextension 417, respectively 416, extending in thelongitudinal direction 13 of thewindow 1 beyond the topsash member 9. The third andfourth sides extensions 416, respectively 417, of theside sash members 12, respectively 11. In this way thetop sash module 411 is placed essentially outside the area delimited by thesash structure 3, i.e. essentially outside the sash plane. -
[0020] The connection between thethird side 413 and theextension 416, respectively thefourth side 414 and theextension 417, may be achieved in any suitable way, such as by a friction-locking or snap-locking mechanism or even by means of an adhesive or an attachment means such as a screw or a nail. -
[0021] In a preferred embodiment shown inFig. 3 , the third andfourth side attachment member 435, respectively 438, while theextensions corresponding receiving member 437, respectively 439. In the embodiment shown, theattachment members slot 436, respectively 440, while the receivingmembers extensions slots attachment members attachment members members top sash module 411. -
[0022] Thetop sash module 411 is furthermore provided with one ormore ventilation openings 418. For ventilation purposes air is allowed to pass through theventilation openings 418 when theventilation flap 400 is in its open position, while theventilation openings 418 are closed when theventilation flap 400 is in its closed position abutting thetop sash module 411. The amount of air passing theventilation openings 418 may be regulated by means of the intermediate positions of theventilation flap 400. In the closed position of theventilation flap 400, thesash module 411 forms a sealing stop for theventilation flap 400. -
[0023] Thetop sash module 411 may furthermore be provided with at least one, preferably two,protrusions 434, which are arranged in connection with a ventilation opening 418. The protrusion(s) 434 is intended for acting as a guide means for an element 406' connecting thepivot connection 406 and thelock 17. -
[0024] This arrangement has the advantage compared with the known solutions, that the ventilation arrangement provided by thetop sash module 411 and theventilation flap 400 in combination is positioned essentially outside the plane defined by thesash members top sash module 411 and theventilation flap 400 are positioned in such a way as to enable the area available for thepane 4 to be increased, which in turn allows for more light to be transmitted through the window into a building in which it is installed. Particularly, measurements have shown that this arrangement may increase the pane area by 8 to 9 %, particularly about 8 %. Another advantage provided with this arrangement lies in that thetop casing 500 may be made smaller, which in turn saves material and thus provides for awindow 1 which is cheaper to manufacture. -
[0025] Furthermore, thetop sash module 411 may be adapted to function as a holder for receiving a gasket or sealing strip for sealing the gap between thetop sash module 411 and thetop frame member 5 in the closed position of thewindow 1. To this end thesecond side 415 of the top sash module may be provided with a recess orgroove 419 extending substantially in the total longitudinal extension of thetop sash module 411. -
[0026] Preferably, therecess 419 is arranged such as to be flush with a corresponding recess or groove in the respectiveadjacent extensions side sash members top sash module 411, such as to enable providing thewindow 1 with a preferably circumferentially extending sealing 18 for sealing the gap between thesash 3 and theframe 2 in the closed position of thewindow 1. -
[0027] Referring now toFigs 4 and 5 , the window furthermore comprises at least onebarrel bolt 420 comprising ahousing 421 with a first, preferably open,end 427 and a second, preferably closed,end 428, and abolt 422 arranged in thehousing 421 in such a way as to be longitudinally displaceable in relation to thehousing 421 from a first position in which thebolt 422 is placed completely within the housing 421 (cf.Fig. 5 ) to a second position in which thebolt 422 is placed at least partially outside thehousing 422. Thebarrel bolt 420 is mounted in arecess 426 in the topsash member 9 having substantially the same length as thebarrel bolt 420 in such a way that theopen end 427 of thehousing 421 is arranged flush with a transversal end surface of the topsash member 9, while the closedend 428 of thehousing 421 is placed adjacent to or in contact with an end of therecess 426 opposite the transversal end surface of the topsash member 9. Thebarrel bolt 420 is preferably secured to the topsash member 9 by means of a fastening means such as a screw or the like, which is passed through ahole 425 in thehousing 421 as well as anoblong hole 442 in thebolt 422, theoblong hole 442 ensuring that thebolt 422 may be displaced longitudinally within the housing. -
[0028] -
[0029] Thebarrel bolt 420 comprises an operating means 423, such as a grip, extending through anoblong hole 424 provided in thehousing 421 of thebarrel bolt 420, the extension of the oblong hole 424 (and/or the oblong hole 442) defining the extension of the longitudinal displacement of thebolt 422 in thehousing 421. -
[0030] The operating means 423 extends at an angle, preferably at a right angle, with respect to the longitudinal direction of thebolt 422, and has a length I of preferably between 1 and 3 cm. -
[0031] The operating means 423 extends at an angle, preferably at a substantially right angle, with respect to thebolt 422. Preferably, in the mounted position of thebarrel bolt 420, the operating means 423 has an angle with respect to thewindow 1 such that it extends substantially in the direction of thedepth axis 15 of thewindow 1, and a length such that it terminates approximately level with the surface of thetop sash module 411 facing away from thehousing 421 of thebarrel bolt 420. In other words the length of the operating means 423 is such that it in the mounted position of thebarrel bolt 420 extends in the direction of thedepth axis 15 of thewindow 1 in a distance corresponding to but not exceeding the sum of the distance between thebarrel bolt 420 and thetop sash module 411 and the thickness of thetop sash module 411. -
[0032] This provides for abarrel bolt 420 which is easy to grip and consequently to operate, particularly when applied in combination with the top sash module described above. -
[0033] The operating means 423 is preferably shaped in such a way as to providesurfaces 423', 423" adapted for being securely gripped between two human fingers. -
[0034] Thebarrel bolt 420 is intended for releasably locking thesash 3 to theframe 2 in a position of thewindow 1 in which thesash 3 is rotated past its normal opening range. Such an angle may be close to 180 degrees, but may also be smaller, depending i.a. on the dimensions of the frame and the sash. Thesash 3 is rotated around thepivot hinge axis 21 with respect to theframe 2 and the engagement between parts of the hinge is released in a manner known to the person skilled in the art in such pivot hinges, such as to enable a user to clean the outside surface of thewindow 1, particularly of thepane 4, from within a building in which thewindow 1 is mounted. To this end at least one of theside frame members Figs 1 to 5 ) adapted for receiving thebolt 422 of thebarrel bolt 420 at least partially, which recess may optionally comprise an insert preferably made of plastic. The insert may comprise retaining means such as barbs for retaining it in the recess. Hence, thebarrel bolt 420 is particularly useful for centre hung and semi-centre hung windows, but may nevertheless be used for any type of window. -
[0035] Referring now toFigs 6 to 8 , a slightly different embodiment of the window is shown. -
[0036] Here, anaperture 711 intended for receiving the bolt of thebarrel bolt 420 is shown at the bottom of theframe side member 7. Thisaperture 711 is intended for receiving the barrel bolt in the cleaning position, i.e. when the sash has been turned past its normal opening angle. -
[0037] Anotheraperture 712 is positioned near the top of theframe side member 7. If desirable, thisaperture 712 makes it possible to provide a further ventilating position at a relatively small angle, but still allows for more air entrance than by theventilation flap 400 in itself. -
[0038] It should be noted that the above description of preferred embodiments serves only as an example, and that a person skilled in the art will know that numerous variations are possible without deviating from the scope of the claims.
