Description
Title of Invention
Roof window with improved ventilation.
Technical Field
The present invention relates to a roof window comprising a frame having a plurality of frame members including a top member, two side members and a bottom member, a sash having a plurality of sash members a top member, two side members and a bottom member, of which at least the sash top member includes a separate sash top unit forming part of or constituting the sash top member, and at least one ventilation device including a plurality of ventilation openings to provide ventilation between an exterior side and an interior side of the window.
Background Art
Such windows come in a number of varieties and models. Typically, the windows are generally equipped with operating means as well as ventilation means. Some roof windows are provided with a ventilation flap rotatably connected to the sash, which at the same time fulfils the role of operating means to release and activate a lock cooperating with the frame.
In combination with a top sash unit connected to the outer side of the sash, the solution with a pivotally connected ventilation flap has proven to function particularly well as describe in for instance Applicant’s European patent No. EP 2 751 355 B1.
However, in some roof windows, it is desirable to provide the roof window with a ventilation device of simpler kind, and to separate the operation of the opening of the window from the ventilation device.
Summary of Invention
It is therefore the object of the invention to provide a roof window, in which the ventilation through the sash top member is satisfactory but which at the same time makes it possible to provide a flexible solution.
This is achieved with a roof window of the kind mentioned in the
DK 2018 70326 A1 introduction, which is further characterised in that said ventilation device is accommodated in the sash top unit, and that said at least one ventilation device is releasably connected to the sash top unit by non-positive engagement means.
By forming the ventilation device in the sash top unit and at the same time allowing the ventilation device to be releasably inserted into and removed from the sash top unit, a number of advantages are obtained. Based on the recognition that the need for maintenance or even replacement of components of the ventilation device surpasses the maintenance interval of other parts of the roof window, it is now easy and flexible to simply remove the ventilation device from the top sash unit, and then either re-introduce the same ventilation device, or a new one, when needed. The releasable engagement by nonpositive engagement only, renders the use of structure penetrating fastening means such as screws redundant. This is particularly an advantage in those circumstances that the top sash unit is made of a plastic material.
In a presently preferred embodiment, the ventilation device has a longitudinal configuration extending between a first end and a second end, a length dimension being defined between the first and second ends substantially in parallel with a length direction of the sash top member. This provides for a relatively wide ventilation opening, while at the same time retaining a discreet appearance of the ventilation device.
In a preferred development of this preferred embodiment, the engagement means are positioned at one or both of said first and second end and comprise at least one biasing device connected to the ventilation device and contacting the top sash unit of the sash top member in frictional engagement. This provides for excellent retention of the ventilation device in the top sash unit, while at the same time making retraction of the ventilation device easy and logical.
In a further presently preferred embodiment, the biasing device of the engagement means of the ventilation device comprises a spring lever having at least one engagement portion to contact a corresponding flange portion on the top sash unit in frictional engagement, and at least one fastening portion
DK 2018 70326 A1 for fastening the spring lever to the remaining parts of the ventilation device. A spring lever provides a mechanically simple and reliable contact with the top sash unit, while providing sufficient stability in the position of use.
Other presently preferred embodiments and further advantages will be apparent from the subsequent detailed description and drawings.

Description of Embodiments
Referring initially to Fig. 1, the general configuration of a roof window is shown.
The roof window here comprises a primary frame in the form of a stationary frame 1 configured for installation in an inclined roof surface, here by means of mounting brackets 3 provided at the corners, but other installation principles may be applied as well. The frame 1 comprises a plurality of frame members, here including a frame top member 11, two frame side members 12 and 13, and a frame bottom member 14.
At least one secondary frame is connected to the stationary frame 1, in the embodiment shown a sash 2 carrying a pane 4. The sash 2 is pivotally connected to the stationary frame 2 in order to be able to rotate the sash 2 to an open position. To that end, the sash 2 is provided hinge fitting part (not shown), cooperating with a counterpart hinge fitting part (not shown) provided on the frame 1. The sash 2 comprises, corresponding to the frame 1, a sash top member 21, two sash side members 22 and 23, and a sash bottom member 24. In principle, the hinge axis could be located arbitrarily in the roof window, but is here substantially centre-hinged. The roof window could be top-hinged as well, meaning that the hinge axis is located near the frame top member 11 and the sash top member 21.
From the shown closed position, the user operates the operating device of the window, here in the form of a handle 5 at the bottom member 24 of the sash 2. Further details of the handle 5 are the subject of Applicant’s copending patent application having the same filing date as the present application, and the contents thereof are incorporated herein by reference.
Finally, the roof window is provided with a ventilation device 6 accommodated in a top sash unit 7, acting to allow passage of air also in the closed position of the window.
In the following, embodiments of the roof window will be described with particular focus on the ventilation device and the top sash unit. It is recognised that the top sash unit 7 has a length dimension, a width dimension and a thickness dimension configured to cover a substantial part of the sash top
DK 2018 70326 A1 member 21. As roof windows come in different sizes, it is understood that the person skilled in the art will be able to select such suitable length and width dimensions without undue burden.
Referring initially briefly again to Figs 1 to 3, the roof window is shown to comprise frame 1 with top member, two side members and a bottom member 11, 12, 13, 14, and sash 2 with top member, two side members and a bottom member 21,22, 23, 24.
At least the sash top member 21 includes a separate sash top unit 7 forming part of or constituting the sash top member 21. Other sash members may in principle be provided with separate sash units as well to form part of or constitute the sash member in question. The principles of such a separate unit could in principle be transferred to the frame as well, and also applies to fixed, i.e. not openable windows.
More than one ventilation device 6 may be provided in one sash or frame member. In the following, only one ventilation device 6 accommodated in the top sash unit 7 forming part of the sash top member 21 will be referred to.
Referring now to Figs 4 to 8, the ventilation device 6 includes a plurality of ventilation openings 67 to provide ventilation between an exterior side and an interior side of the window. The ventilation openings 67 are formed between bars 66 spaced apart by a certain distance.
In the embodiment shown, the ventilation device 6 has a longitudinal configuration extending between a first end 6a and a second end 6b, a length dimension being defined between the first and second ends 6a, 6b substantially in parallel with a length direction of the sash top member 21, a height dimension perpendicular to the length dimension substantially in parallel with a width direction of the sash top member, and a thickness dimension perpendicular to the length dimension substantially in parallel with a thickness direction of the sash top member.
In the embodiment shown, the ventilation device 6 functions as a wellknown so-called click valve, in which a cover section 62 surrounded by border section 61 includes two push buttons 63 which may be activated independently
DK 2018 70326 A1 of each other such that if one is activated, the cover section 62 will assume an inclined position and allowing air to flow in and out via a wedge-shaped opening, and if both push buttons 63 are activated, the cover section 62 will assume a position substantially in parallel with the border section 61. The operating principles resemble those of a pen, i.e. reactivation of the lock is achieved by pushing the push buttons 63 back. Such principles are well-known and will not be described in further detail, although snap lock 60 responding to the activating push-buttons 63 is shown in Fig. 9.
Opposite the cover section 62, a back section 64 is provided adjacent but retracted from the border section 61. In the embodiment shown, engagement means generally designated 65 are provided at the back section 64. The engagement means 65 are non-positive, i.e. force dependent only, and do not require removal of an obstacle in order to be released. The engagement means 65 serve to releasably connect the ventilation device 6 to the sash top unit 7.
In the embodiment shown, the engagement means 65 are positioned at both of the first and second end 6a, 6b and comprise at least one biasing device 69 connected to the ventilation device 6 and contacting the top sash unit 7 of the sash top member 21 in frictional engagement, as will be described in further detail below.
In order to accommodate the ventilation device 6, the top sash unit 7 is provided with a track 75. The top sash unit 7 is provided with a plurality of ventilation openings 77 to match the ventilation openings 67 of the ventilation device 6, also separated by bars 76.
Furthermore, top sash unit 7 forms part of the sash top member 21 and has a longitudinal extension defining a length exceeding the length of the ventilation device 6. The top sash unit 7 is connected to the remaining parts of the sash top member 21 at a respective longitudinal end 7a, 7b.
The top sash unit 7 has a front face 71 to which the border section 61 of the ventilation device 6 is substantially flush. A top face 72 adjoins the front face 71. At a distance in the height direction from the top face 72, a ledge 78 is provided. Bars 76 thus extend between the ledge 78 and the underside of the
DK 2018 70326 A1 top face 72.
In the embodiment shown, the top sash unit 7 is accommodated in a recessed portion 211 of the sash top member 21 and is held by its longitudinal ends 7a, 7b to a respective end portion 210 of the sash top member 21, the end portions 210 of the sash top member 21 being here formed by extended portions of the sash side members 22, 23. A flange portion 73 at each end 7a, 7b of the top sash unit 7 contacts an abutment portion 212 associated to a transition portion 213.
Although the contact between the flange portions 73 and the end portions 210 may be sufficient, it is preferred that the top sash unit 7 is fastened to the remaining parts of the sash top member 21 by means of fastening means, such as screws, introduced through a plurality of apertures 74.
The top sash unit 7 may for instance be provided as a moulded element and may be used both with a sash of wood and of a plastic material such as polyurethane (PU). As one example, the top sash unit 7 is a plastic injection moulded element, with a surface adapted to be painted with a lacquer in order to resemble the surface finish of PU
Turning now to Figs 9 to 11 and Figs 12a and 12b, another embodiment will be described with particular focus on the biasing device of the engagement means of the ventilation device 6. There are only slight differences between the above-described embodiment and the other embodiment, and elements having the same or analogous function carry the same reference numerals.
The biasing means comprises a spring lever 69 having at least one engagement portion 691, 692 to contact a corresponding flange portion 791, 792 on the top sash unit 7 in frictional engagement. Furthermore, at least one fastening portion 693, 694 is provided for fastening the spring lever 69 to the remaining parts of the ventilation device 6.
Here, the spring lever 69 is formed as a substantially plate-shaped element comprising a number of bent portions with a length direction substantially parallel with the height dimension of the ventilation device 6, said bent portions including said at least one fastening portion 691,692.
DK 2018 70326 A1
A first and a second engagement portion 691, 692 are provided as each an inclined plate section at opposite ends of a substantially plane bridge portion 690. In this way, the first and second engagement portions 691, 692 are allowed to flex resiliently when contacting the top sash unit 7.
A first and second fastening portions 693, 694 are provided as respective folded sections between a respective engagement portion 691,692 and said bridge portion 690.

Other details include opening 696 in plane section 695 of each fastening portion 693, 694. In addition to being an advantage during manufacture, this also assists in the resilient flexing of the engagement portions 691, 692.
Referring in particular to Fig. 11, the back side of the ventilation device 6 comprises an end block 680 at each longitudinal end 6a, 6b, between which a first and a second ledge 681, 682 extend. It is apparent that the bars 66 separating the ventilation openings 67 extend in the height direction between the first and second ledges 681, 682.
Simple fastening of the spring lever 6 to the remaining parts of the ventilation device 6 is here obtained in that the respective folded sections forming the first and second fastening portions 693, 694 of the ventilation device are clamped on to the respective first and second ledge 681, 682 of the ventilation device 6.
The parts of the ventilation device 6 are typically made of moulded plastic parts. However, the biasing means, here the spring lever 69, may be made of metal, for instance spring steel.
Finally, returning to Fig. 4, it is shown how the sash top member 21 is provided with an additional set of ventilation openings, preferably in the form of a first plurality of vent slits, here in the form of recess vent slits 214, facing the top sash unit 7 and a second plurality of vent slits, here in the form of inner vent slits 215, in connection with the recess vent slits 214 and facing the interior side of the window. The sash 2 is also provided with a lock bolt 216 interacting with
