Description
Title of Invention
Roof window with improved coupling mechanism.
Technical Field
The present invention relates to a roof window, particularly for installation in an inclined roof surface, comprising a primary frame, at least one secondary frame, such as a sash and/or an intermediate frame, and a lifting device including a lifting arm inserted between the primary frame and the at least one secondary frame, the lifting arm having a first end rotatably connected with a sledge system slidably connected with the primary frame in a sledge guidance and a second end rotatably connected with the at least one secondary frame, the lifting device furthermore including a spring assembly configured to be coupled to the sledge system and in turn the first end of the lifting arm by means of a coupling mechanism, such that the spring assembly is able to assume an uncoupled condition and a coupled condition relative to the sledge system. The invention furthermore relates to a method for installing a secondary frame in a roof window.
Background Art
Windows for installation in an inclined roof surface include the pivoting type hinged at or near the centre, the top-hinged type, and finally the roof windows that are top-hinged during normal operation but which pivot for cleaning. Examples of top-hung windows that pivot for cleaning are for instance disclosed in Applicant’s WO-A-89/10460, EP 0 733 146 B1, EP 1 873 323 B1 and EP 2 762 665 A2. To make it possible to pivot the window sash approximately 180° to a convenient cleaning position, the sash structure is connected with an intermediate frame with frame arms, which in the closed position of the window are positioned between the upper parts of the frame and sash side members, and which during normal use of the window as a top-hung window follow the sash side members.
In roof windows in which the operation takes place either entirely or partially about a hinge axis at the top, it is known to balance at least part of the
DK 2017 70889 A1 weight of the movable components by means of a lifting device inserted between a pair of associated side members of the stationary frame and the sash element, respectively, and having one end pivotally connected with one of the side members while its other end is hinged to a sliding shoe displaceable along the other side member, said shoe being urged by a tension spring in a direction so as to exert an outwardly directed pressure through the lever on the sash element. The purpose of this arrangement is to facilitate opening the window, and the dimensions may be chosen so that the spring can retain the top-hinged frame in equilibrium in a desired opening position.
Coupling and uncoupling of the spring assembly of such a window is known from e.g. EP 0 081 333 B1, wherein one end of the sash lifting-lever presents at least two pivot points having different distances from the pivot point at the other end of the lever, and being located to successively becoming operative during the opening of the window and successively increasing the effective length of the lever. Another disclosure is found in WO 89/010460 A1, wherein a slide shoe and a pre-stressed spring provided with coupling means adapted to be brought into engagement with each other during the installation of the window is described. Said coupling means include a tie rod connected on one end to said spring and to a coupling element on its other end. The coupling element engages a receiving recess in the sliding shoe by means of a traverse pin. This window however requires the installer to lift the entire weight of the sash with one hand while the other hand is placed in a potentially dangerous position between sash and frame during installation and dismantlement. In addition, window sashes are progressively gaining in weight as modern sashes include additional elements offering a greater range of functionalities, and better insulation properties require greater amount of materials being included in the construction of frames, panes and sashes.
Considering this, it is presently a challenge to provide a spring assembly and sledge system coupling mechanism that can bear current load requirements while offering an intuitive and easily manageable roof window simplifies installation and dismantlement.
DK 2017 70889 A1
Summary of Invention
It is therefore the object of the invention to provide a roof window, in which the secondary frame is easily installed and dismantled.
This is achieved with a roof window of the kind mentioned in the introduction, which is furthermore characterised in that the coupling mechanism comprises a first coupling member associated with the spring assembly and adapted to cooperate with a second coupling member associated with the sledge system, in that the first coupling member includes a hook element, and the second coupling member includes receiving means formed in the sledge system and configured to cooperate with said hook element in the coupled condition, in that the hook element is configured to assume at least a nonengagement position and an engagement position, and in that the coupling mechanism furthermore comprises a coupling plate arranged to assume at least a first position corresponding to the coupled condition and a second position corresponding to the uncoupled condition, the coupling plate allowing the hook element to assume said non-engagement position.
It is thereby possible to couple and uncouple the spring assembly from the sledge system by manually positioning the coupling plate in the selected position and opening and closing the sash to either release or engage the coupling element. The coupling plate stays in the selected position until it is reactivated, this allowing for the installation or dismantling of the sash and/or intermediate frame in the stationary frame free of coupling of the coupling element with the sledge system and thus without interference of the bias of the spring assembly.
In a second aspect of the invention, a method for installing a secondary frame to a primary frame of a roof window is provided.

Description of Embodiments
Referring initially to Fig. 1, the general configuration of a roof window which is top-hinged during normal operation and which pivots for cleaning is shown. Such a window is shown and described in further detail in Applicant’s above-mentioned European patent No. 0 733 146 B1, the contents of which
DK 2017 70889 A1 are hereby incorporated by reference. In Fig. 1, a lifting device 10 is indicated, which, referring now also to Fig. 2 to 9, forms part of a first embodiment of the roof window according to the present invention.
The roof window comprises a primary frame in the form of a stationary frame 1 configured for installation in an inclined roof surface. At least one secondary frame is connected to the stationary frame 1, in the embodiment shown a first secondary frame in the form of a sash 2 carrying a pane 4, and a second secondary frame in the form of an intermediate frame 3. The intermediate frame 3 is fastened to the stationary frame at a top mounting fitting 5, and the sash 2 is hinged at the top of the roof window, via the intermediate frame 3 to the stationary frame 1, to render the roof window top-hung during normal operation. The sash 2 is also pivotally connected to the intermediate frame 3 in order to be able to rotate the sash 2 to provide access to the outside of the pane 4, for instance for cleaning purposes. To that end, the intermediate frame 3 is provided with a frame hinge part 6 of pivot hinge fitting. Although not shown in detail, it is clear to the skilled person that the sash 2 is provided with the counterpart sash hinge part of the pivot hinge fitting.
A lifting device 10 is composed of a spring arrangement 20 and a sledge system 30 which cooperate to assist in the opening of the window, that is, bringing the secondary frame or frames to an angled position relative to the primary frame. Here, from a closed position, the user operates the operating device of the window in the form of a handle 7 at the bottom member of the sash 2. The bias of the spring arrangement 20 of the lifting device 10 acts on a lifting arm 14 inserted between the stationary frame 1 and the intermediate frame 3. In turn, the lifting arm 14 exerts a moment on the intermediate frame and hence to the sash relative to an axis through a top hinge pin 11. In combination with the force exerted by the user on the handle 7, transferred to a lifting moment, the moment resulting from the weight of the sash 2 with pane is overcome. Closing the window from the open position entails the opposite movements of the sash 2 and relevant parts of the lifting device 10. A similar lifting device may be provided at each side of the roof window. Finally, the roof window is provided with a ventilation device 8 acting to allow passage of air
DK 2017 70889 A1 also in the closed position of the window.
In further detail, the lifting arm 14 having a first end 12 rotatably connected with a sledge system 30 slidably connected with the primary frame 1 in a sledge guidance 16 and a second end 13 rotatably connected with the at least one secondary frame 3, the lifting device 10 furthermore including a spring assembly 20 configured to be coupled to the sledge system 30 and in turn the first end 12 of the lifting arm 14 by means of a coupling mechanism, such that the spring assembly 20 is able to assume an uncoupled condition and a coupled condition relative to the sledge system 30.
Figs 5 and 6 show the general components of the spring assembly 20 of a roof window. Further details and advantages of the particular spring assembly 20 are the subject of Applicant’s co-pending patent application filed on the same day as the present application, and is shown for information purposes only in Figs 21 to 24. The present invention is however applicable to any kind of spring assembly. Thus, the general components of the spring assembly are: a buffer spring system 28 acting as an auxiliary system to a main spring system 29. In order to adapt one and the same spring assembly to varying roof inclinations, an adjustment means is provided in the form of a movable adjustment plate 26 which is placed in one of several recesses 27a in a spring casing 27 accommodating the buffer spring system 28.
According to the present invention, the coupling mechanism comprises a first coupling member 21 associated with the spring assembly 20 and is adapted to cooperate with a second coupling member 31 associated with the sledge system 30, the first coupling member including a hook element 21 and the second coupling member including receiving means 31 formed in the sledge system 30 and configured to cooperate with said hook element 21 in the coupled condition, the hook element 21 being configured to assume at least a non-engagement position and an engagement position, and the coupling mechanism furthermore comprising a coupling plate 25 arranged to assume at least a first position corresponding to the coupled condition and a second position corresponding to the uncoupled condition, the coupling plate 25 allowing the hook element 21 to assume said non-engagement position.
DK 2017 70889 A1
Operation of the presently preferred embodiments will be described in further detail in connection with Figs 12a to 12h.
In the embodiment shown, the hook element 21 of the first coupling member has at least one hook portion 214 facing the sledge system 30. This provides for a particularly easy and safe coupling procedure.
Even though the coupling mechanism could function well with only a single hook and receiving means pair, it is preferred that the hook element 21 as shown has a U-shaped configuration including a base plate portion 212 and two flange portions 213, one hook portion 214 being provided at each of the flange portions 213.
Turning now in particular to the exploded view of Fig. 7 and the detailed individual views of Figs 8a to 8e, the spring assembly 20 comprises a tension rod 22 including a rod portion 221 extending substantially along the length of the spring assembly 20, and a head portion 222 facing the hook element 21, the tension rod 22 being provided with at least one inclined portion 223, 224 at the transition between the head portion 222 and the rod portion 221.
In the present embodiment, the hook element 21 is provided with an aperture 211 in the base plate portion 212 to allow passage of the tension rod 22 such that the head portion 222 of the tension rod 22 is retained within the U-shape at the front side of the base plate portion 212 and the rod portion 221 at the back side.
The coupling plate 25 of the coupling mechanism has a base portion 252 located at the back side of the base plate portion 212 of the hook element 21 and is provided with an oblong aperture 251 to allow passage of the rod portion 221 of the tension rod 22, and wherein the coupling plate 25 is slidable in the plane of the base portion 252 substantially perpendicularly to the rod portion 221 such that when in a bottom position, the hook portion 21 is capable of assuming its engagement position, and in a top position, the hook portion 21 is kept in its non-engagement position.
Furthermore, the coupling plate 25 is here provided with a bottom flange 253 formed on the base portion 252 to abut on the at least one inclined
DK 2017 70889 A1 portion 223 in the non-engagement position via the base plate portion 212. This brings about the actual retention of the hook element 21 in its non-engagement position in the embodiment shown.
The coupling plate 25 is provided with a cut-out 254 at the top of the base portion 252 to form at least one, preferably two, upstanding lugs 255. This eases the application of tools and the re-entry into the coupling position. Furthermore, the cut-out 254 allows for accommodation of reinforcement or stiffening elements for the sash.
In principle the configuration of the spring assembly 20 may be carried out in any suitable manner as long as it fulfils the requirements due to the relatively large forces involved. A robust structure as in the present embodiment includes an angle element 23 provided near the head portion 222 of the tension rod 22, having an aperture 231 to allow passage of the rod portion 221 of the tension rod 22.
Here, an end piece 24 is provided, having an aperture 241 to allow passage of the rod portion 221 of the tension rod 22, the end piece 24 furthermore having an upstanding wall 242, on which a protrusion 243 is formed to surround the aperture 241 of the end piece 24, and wherein two protruding flanges 244 are provided at either side of the upstanding wall 242 to define a track 245.
As shown, the angle element 23 is provided with an upstanding leg 232 and a bottom leg 233, the aperture 231 of the angle element 23 being provided in the upstanding leg 232, and wherein two protruding flanges 234 are provided substantially in parallel to the bottom leg 233 and each defining a gap 235 relative to the upstanding leg 232.
In the assembled state, the end piece 24 is positioned with the back side of its upstanding wall 242 abutting the front side of the upstanding leg 232 of the angle element 23, between the bottom leg 233 and the protruding flanges 234, and wherein the base portion 252 of the coupling plate 25 is received slidably in the track 245 of the end piece and the respective gaps 235 of the angle element 23.
In order to obtain a smooth movement during the coupling procedure,
DK 2017 70889 A1 each flange portion 213 of the U-shaped the hook element 21 here includes an apex 210 at the front end, a rounded transition 215 between the apex 210 and the hook portion 214, a bottom edge portion 218 between the hook portion 214 and the base plate portion 212, an opposite top portion 217, and at least one inclined edge portion 216, 219 between the top portion 217 and the apex 210.
Further details of the sledge system 30 are shown in a second and presently preferred embodiment in Figs 10 to 11 and 13 to 16. Elements having the same or analogous function as in the first embodiment carry the same reference numerals.
In the preferred embodiments shown, a sledge 31 of the sledge system 30 comprises a bottom portion 310, a first wall portion 311 and a second wall portion 312, one receiving recess 314 being preferably provided at each of the transitions between the first wall portion 311 and the bottom portion 310 and between the second wall portion 312 and the bottom wall portion 310, and wherein a hole 315 is provided in the first wall portion 311 and a hole 316 is provided in the second wall portion 312 for receiving an axle 40 connected to the first end 12 of the lifting arm 14.
In the presently preferred embodiments described herein, the receiving means of the second coupling member include at least one receiving recess 314 in the sledge 31 of the sledge system 30. The second coupling member could also take other shapes. One conceivable, alternative solution would be to utilise the axle 40 as receiving means. This alternative solution is shown as the fourth embodiment shown in Fig. 20.
Further details of the axle 40 shown in Figs 1 7 to 1 9 are given for information purposes only and are the subject of Applicant’s co-pending patent application filed on the same day as the present application.
In order to control the frictional forces more precisely at the movement of the sledge system 30 in the sledge guidance 16, the sledge system 30 comprises a runner 32 in the embodiment shown, configured to accommodate the sledge 31 and being provided with at least one recess 324 opposite the respective receiving recess 314 of the sledge 31. Further details of the runner 32 are shown in Figs 15 to 17 for information purposes only; such details are
DK 2017 70889 A1 the subject of Applicant’s co-pending patent application filed on the same day as the present application. It is noted that the present invention is applicable also to sledge systems in which there is no runner, or a runner of a different configuration. In the embodiment shown, the runner 32 is formed of a plastic material such as POM which may also be provided with a coating of for instance Teflon® or other treatment having the function to act as a lubricant to reduce the friction.
The narrowing 313 on the runner 32 is made for reasons of space availability. By forming the runner slenderer in one side, it is possible to make 322a thicker, and tolerances are accommodated in the side where 322 is - in that way the axle 40 is guided such that the end 402 does not protrude to wear on the side of the guidance.
An edge portion 328 is provided as a cut-out in order to allow space for other parts of the assembly. A flange portion 329 scrapes the guidance to the sides of the guidance.
In principle, the coupling mechanism may be designed in any suitable manner and operated accordingly, as long as the fundamentals as outlined initially are fulfilled. As will be understood from the following description of the operational steps performed during coupling and uncoupling of the spring assembly 20 from the sledge system 30 in the embodiments shown and described in the above with reference to the sequence of Figs 12a to 12h, the hook element 21 of the first coupling member is in the presently preferred embodiments arranged to slidably contact the sledge system 30 in one direction and to engage said second coupling member 31 in another direction, namely by being forced in the opposite direction to ensure engagement with the first and second coupling members by the components of the lifting device itself. Not all elements are indicated by reference numerals in Figs 12a to 12h for ease of readability and it is referred to the above description of the remaining Figures for detailed explanations.
Turning first to Fig. 12a, the roof window is shown in its closed condition, that is the secondary frame or frames are lying substantially in parallel with the primary frame. Here, the intermediate frame 3 represents the
DK 2017 70889 A1 secondary frames, and the position of the sledge guidance 16 and the spring assembly 20 indicate the corresponding position of the stationary frame 1 although not shown, i.e. here substantially horizontal for reasons of clarity, even though the stationary frame 1 will most often be installed in an inclined roof surface prior to coupling the spring assembly 20 to the sledge system 30. The coupling mechanism is not yet active, and the sledge system 30 is consequently located at a distance from the spring assembly 20. From the break-out enlarged view of Fig. 12a is apparent the position of the coupling plate 25 in its first position, i.e. bottom position, and corresponds to the engagement position of the hook element 21 in which coupling is possible.
When opening the window by rotating the intermediate frame 3 about the top hinge pin 11, the lifting arm 14 rotates as well, and the sledge system moves in the direction of the spring assembly 20 and its associated first coupling member in the form of hook element 21. When approaching the position shown in Fig. 12b, the hook element 21 slides up on the sledge 31 and is able to rotate slightly on the tension rod 22, as the base plate portion 212 of the hook element 21 is able to move relative to the inclined portion 223 on the back side of the head portion 222. The coupling plate 25 is still in its first, or bottom position. During the continued movement in the opening direction of the intermediate frame 3 and the ensuing translational movement of the sledge system 30, the hook portions 214 of the hook element 21 will reach a position just above the receiving recesses 314. As the spring assembly 20 is biased and exerts a pull in the tension rod 21, to the left in Fig. 12b, the hook element 21 will be subjected to a clockwise moment which in turn forces the hook portions 214 to enter the receiving recesses 314 of the sledge 31.
Once the coupling has taken place, the hook element 21 withdraws further to the left due to the bias of the spring assembly, the hook portions 214 are drawn into stable engagement with the receiving recesses 314 in the sledge as shown in Fig. 12c.
The window is now ready for normal operation, and during the subsequent closing of the intermediate frame 3, the movement of the lifting arm 14 pulls the sledge system 30 towards the top of the window, i.e. to the right as
DK 2017 70889 A1 shown in Fig. 12d. The closing movement takes place during simultaneous further bias of the spring assembly 20 as is known per se.
Should the need for removal of the secondary frame or frames arise, the roof window is prepared for uncoupling by first rotating the intermediate frame 3 to an open position. Then, the coupling plate 25 is brought from its first or bottom position to its second or top position by an upwards movement, indicated by arrow A in Fig. 12f. In the embodiment shown, the window is not entirely open in the position of Fig. 12f, that is, the sledge system 30 is not in its left-most position but distanced from the spring assembly 20 by some millimetres. In practice, the sash is rotated to its fully open position and then moved slightly back in the closing direction such that the coupling plate 25 is free to be moved upwards. In this position the coupling plate is held in its upper most position by means of friction. The hook element 21 is still engaged with the sledge system 30 as the hook portions 214 are gripping the recesses 314 of the sledge 31 until the user grabs the sash and lifts it. During this movement, the hook element 21 is allowed to turn upwards in the counter-clockwise direction. This brings the hook element 21 to its non-engagement position in which coupling is not possible. This action is brought about in that the bottom flange 253 of the coupling plate 25 abuts on the back side of the base plate portion 212 of the hook element 21. The hook element 21 is thus affected by a counter-clockwise moment which keeps it in the non-engagement position. The secondary frame(s) may now be dismantled from the primary frame, here thus the intermediate frame 3 with sash 2 and pane 4 lifted off the connection with the stationary frame 1. The lifting of the coupling plate 25 may in principle take place in any suitable manner. However, in order to ensure that unwarranted release does not take place, use of a suitable tool is preferably prescribed.
Bringing the roof window back to a position prepared for coupling takes place by simply rotating the intermediate frame 3 in the closing direction. Towards the end of the closing movement, the lifting arm 14 pushes the coupling plate 25 downwards, in the direction of arrow B in Fig. 12h. Once the counter-clockwise moment previously acting on the hook element 21 is released, the hook element 21 is able to rotate in the clockwise direction to
DK 2017 70889 A1 assume the position shown in Fig. 12a.
Above the invention has been described with reference to the sash and frame of a roof window, but it will be understood that it also applies to other frame structures, such as for example door frames.
