Description

The subject of the invention comprises a roof window lining assembly connector, a lining assembly unit and a method for assembling lining around a roof window using the assembly unit.
A lining for a window constructed out of a frame which defines the frame plane, wherein the aforementioned lining contains a panel unit and numerous fittings designed to ensure a connection between the window frame and the lining has been disclosed under EP3792438B1 . Each fitting features a frame fitting section and a lining fitting section, so that the frame fitting section is configured to be connected to the window frame. The frame fitting section features a flange for attaching to a window frame, so that it stretches along the first plane parallel to the frame plane and a bottom section which stretches from the flange at an angle to the frame and which features coupling measures oriented towards the lining in its assembled position. The lining fitting section works with the lining and is configured to be connected to an appropriate lining panel. The lining fitting section features an essentially flat base which abuts the lining outer surface and coupling measures which protrude from the base oriented away from the lining panel, wherein the lining fitting section coupling measures are configured for coupling with frame fitting section coupling measures during assembly of the lining around a window. The frame fitting section bottom section features at least two coupling segments and the base features a single coupling segment in order to make it possible to maintain each lining panel using connectors in the first, partially inserted position and in a completely inserted assembly position relative to the window frame.
The disclosed solution entails attaching a lining around a roof window using a two-part fitting. One section is attached in a lining plate and the other in a jamb groove. The other fitting section is attached in a groove using screws. Both these sections establish a catch type connection. The disclosed solution is complicated and difficult to carry out due to limited assembly space. Assembly connector according to claim 1 solves the aforementioned problem through a non-invasive assembly of the lining, which does not require the application of additional assembly measures in the form of screws or similar.
The aim of the invention is a roof window lining assembly connector. The assembly connector is an elastic element, which once seated in a jamb groove exerts constant pressure on its opposite walls. Whereas the roof window jamb is constructed out of four stiles: upper stile, lower stile and two side stiles, connected to each other to form a closed frame. Each stile features a jamb groove for a lining plate, oriented towards a room interior in which the roof window has been installed. The assembly connector is constructed out of a base with at least one ridge and a stop face, which is at an angle relative to the base. The base ridge and the stop face abut opposite lining groove side walls exerting the aforementioned pressure upon them. The stop face features a top edge, with the axis of rotation of the stop face first and second arm passing through it, making it possible to elastically tilt them relative to one another. Wherein the distance between the stop face first and second arm is d₁, and di>0. Once the assembly connector has been seated in the jamb groove, distance di is less than the distance before it was seated in the jamb groove. In order to limit the maximum distance di reduction, there is a spacer plate between the stop face first and second arms, which defines the minimum distance di between the arms in their assembled position in the jamb groove.
Preferably the distance plate is an extension of the assembly connector base. The stop face also features a bottom edge which connects the stop face second arm with its third arm, and in the region of the largest parallel area between the stop face third arm and second arm, the distance between the second arm and the third arm is d₂, and d₂≥0. Similar to distance d₁, distance d₂ decreases or remains the same once the assembly connector has been seated on the jamb groove. In the preferable embodiment, the assembly connector also features a coupling element to initially support the lining plates in the jamb groove. Preferably the coupling element is a lip protruding from the stop face first arm, and its crest is oriented towards the assembly connector base.
The roof window lining assembly unit according to the invention comprises an assembly connector as described above and a lining. Preferably the assembly unit also includes attachment measures, and screws in particular. The assembly unit lining is constructed out of four plates: top plate, bottom plate and two side plates, so that the length of one edge of each plate, referred to as the adjacent edge, is appropriate for the length of a corresponding roof window jamb stile which it is adjacent to in its assembled state. A top strip, bottom strip and two side strips are attached to each corresponding protective frame plate, and each strip features an attachment arm, so that there is a recess between the attachment arm and strip edge, wherein an edge of an appropriate protective frame plate is seated.
Method for assembling the lining around a roof window using the assembly unit described above entail the following:

preparation of an assembly unit
insertion of at least one assembly connector into each jamb groove. Before inserting an assembly connector into a jamb groove, it is in an expanded position, where distance di reaches its maximum value. When inserted into the jamb groove, it is in a tensioned position, where distance di is smaller than distance di in the expanded position of the assembly connector. Once the assembly connector is seated in the jamb groove, it partially expands so that its base ridges and stop face push against the jamb groove opposing inner side walls. In that position, distance d₁ is smaller than distance di in the expanded position of the assembly connector and greater than or equal to distance di in the assembly connector tensioned position. An analogous process of changing the distance occurs for distance d₂ between the stop face second and third arms.
push-in insertion of the top, bottom and two side lining plates into corresponding jamb grooves with an assembly connector so that the edge of each lining plate abuts against the assembly connector base. Preferably during the insertion of lining plates into jamb grooves, they are initially supported by the jamb using a coupling element. The coupling element constitutes the connector lip which establishes a catch type connection with the lining plate, which preferably features a groove which the lip crest is inserted into. Optionally, the next element of the assembly entails attaching each plate to the jamb using attachment measures, such as screws. Then attachment measures are inserted into each lining plate from the lining plate outer wall side, so that the attachment measures pass through the appropriate lining plate, assembly connector stop face at an angle relative to the assembly connector base all the way to the jamb. In another embodiment, the attachment screw passes in an essentially perpendicular direction through the lining plate and connector stop face all the way to the wall of the room by the jamb or the jamb itself.

In a preferable version of the solution, the assembly unit also comprises a vapour-tight membrane, which in its assembled state shields the inside of the room around the window under the lining, and during assembly its edges are inside a jamb groove. Preferably, a sealing and bonding agent is also present in the jamb groove, and in particular butyl, so that it is located between the connector and the lining groove bottom, and in the embodiment with the vapour-tight membrane, the vapour-tight membrane edge is located between the connector and the sealing agent. In another embodiment, the sealing and bonding agent is applied to the lining plate edge being inserted into a jamb groove.
The assembly connector and the lining assembly unit according to the invention, means that the lining assembly method around the roof window jamb is quick and simple, without the need to use additional attachment measures. The connector is held in the jamb groove by the pressure exerted on the groove walls resulting from connector tension. The connector structure also allows for an initial assembly of the lining by supporting its plates next to the jamb in the connector before it is permanently attached around the window. The connector is also a non-invasive measure for attaching the vapour-resistant film to the jamb.
