Description

BACKGROUND OF THE INVENTION

[0001] The invention relates to a panel attachment assembly, in particular for a roof edge.

[0002] In the state of the art different ways and means are known for attaching panels to buildings. In the embodiments the panels are for instance attached to battens, or used as fascia boards. Most known attachment systems are hard to use, especially on locations that are hard to reach such as eaves. The use in the outside air sometimes during cold weather conditions has not proved to be easy.

[0003] GB-2251004 for instance mentions various attachments and known synthetic snap systems for attaching a roof gutter. Such connections may be difficult to use when it is too cold or too hot.

[0004] WO94/19561 describes a panel provided with grooves and a profile provided with grooves, and an attachment member that is adapted for on the one hand extending into the grooves of the panel and on the other hand extending into the grooves of the profile. Detaching the panel after attaching does not seem to be easy.

[0005] FR2814184 shows assemblies of panels provided with undercut grooves, special fastening clips, and beams provided with grooves on the opposite sides and in which the fastening clips are able to clamp into with resilient legs. In addition the resilient legs extend around the beam. Permanent attachment depends on the (permanent) resilience of the resilient legs of the fastening clips.

[0006] JP60148421 U1 describes specific means for the attachment of a corrugated plate.

[0007] DE102004036328 describes an attachment member for cladding elements provided with a T-groove. The attachment members are provided with a head having swivelling arms which by means of resilient clamping can be brought into position in which they clamp in the T-groove. The resilient clamping is provided with a carrying bar which in case of clamping in a hole should drop into the supporting structure. In addition clamping is possible at positions of a hole in the supporting structure.

[0008] In EP2505738, the inventor disclosed a panel attachment assembly comprising a panel which on one side is provided with a panel rail that is continuous in the longitudinal direction, and a suspension assembly comprising a suspension rail and a suspension member, wherein the suspension member comprises a panel attachment end that is adapted for being accommodated in the panel rail, and a hook member adapted for being able to hook into a continuous rail hook on the suspension rail. In one embodiment the panel comprises a groove at an upper edge, which groove is continuous in longitudinal direction, and the assembly further comprise a retaining assembly having an attachment member and an attachment member, wherein the retaining member comprises a hook fitting in the groove.

[0009] There is room for improvement of this attachment of panels that has been known per se for a long time.

SUMMARY OF THE INVENTION

[0010] It is an object of the invention to provide an improved panel attachment assembly, in particular for attachment of panels or boards at roof edges.

[0011] It is a further or additional object of the invention to provide a panel assembly with which a panel can easily be mounted to a building, for instance in less-favourable weather conditions.

DESCRIPTION OF THE EMBODIMENTS

[0039] Figure 1 shows a cross section of an embodiment of a roof(part), in particular a soffit end 5 or oversail part of the roof with a panel assembly 1, such that the panel 11 forms the batten board. The panel assembly can also be attached to the eave of a roof. Thus, the panel 1 forms a fascia board for the roof. This roof section of figure 1 also shows an inner wall 9, an outer wall 6 with a cavity between them. Usually, the cavity is partially filled with an insulation layer, applied against the outside of the inner wall 9.

[0040] The cross section of figure 1 shows the roof tiles 2 in cross section and hooking behind a tile batten 3. Tile batten 3 is here fixed to a roof sheeting 4. The roof construction comprises a roof insulation layer 50. The roof edge soffit 5 (which, as explained, may also be the eave of the roof) has an outer roof truss 14.

[0041] In the panel assembly, panel 11 is snap-fit to suspension rail 15. To that end, in this embodiment panel 11 has an attachment rail 21 and the suspension rail 15 has a panel attachment groove that extends longitudinally along the suspension rail 15. A panel assembly 1 with panel 11 and suspension rail 15 may also be used in different applications.

[0042] In this embodiment, an upper mounting beam 16 and a lower mounting beam 13 are fixed to the outer roof truss 14. Fixed to the lower mounting beam 13 is a suspension profile 15. The panel 11 is snap-fit to the suspension profile 15.

[0043] In this embodiment, a soffit board 10 is attached to the roof soffit, along one longitudinal edge held by suspension profile 15, and along its opposite edge using a snap-fit mounting provision. The snap-fit mounting provision provides a ventilation channel 12' at the wall-directed edge of the soffit board 10.

[0044] The panel assembly 11 is further designed in such a way that in this roof application a ventilation channel 12 is created along the back surface of the panel 11. In figure a perspective view of part of the construction of figure 2 is shown in more detail. In this embodiment, the upper mounting beam 16 and the lower beam 13 comprise respective cut-outs (or grooves) 17, 18. The cut-outs run cross with respect to the longitudinal direction of the upper and lower beams 16, 13. In this way, a set of ventilation channels is provided, cross with respect to the back surface of the panel 15. It should be clear that the shape, depth and direction if the cut-outs may be optimised for easy production, optimal ventilation, and other reasons. Here, the cut-outs 17 of the upper mounting beam 16 are facing the back surface of panel 11, and the cut-outs of the lower mounting beam 13 are facing away from the panel 11. The cut-outs provide substantially vertical ventilation channels.

[0045] In figure 2, the mounting provision on the suspension profile 15 is clear to see. The suspension profile comprises a mounting groove 19 designed and dimensioned receiving an edge of soffit board 10. This soffit board mounting groove 19 opens opposite the panel 11.

[0046] The various details of the suspension profile 15 will be explained here. The suspension profile 15 has a longitudinal construction attachment flange 36, a flange that extends in longitudinal direction along the suspension profile 15. Here, the construction attachment flange 36 in fact is a single strip. The construction attachment flange 36 provides at one side an attachment surface. The suspension profile can be mounted to a building with this attachment surface applied against a construction part of a building. Here, first the lower beam is mounted against the outer roof truss 14. The suspension profile 15 is mounted against the face of the lower mounting beam 13 that faces away from the building. Its attachment surface 26 is in engagement with the lower mounting beam 13.

[0047] At the other side, facing in opposite direction of the attachment surface 26, the suspension profile 15 abuts against the rear surface 25 of the panel 11. In an embodiment, the surface of the construction attachment flange 36 that is opposite of the attachment surface 26 may abut the rear surface 25 of the panel 11. In the embodiments of the suspension profile 15 that are shown in figures 3-5, a panel abutment 27 is provided for instance by means of a ledge extending in longitudinal direction along the suspension profile 15, and extending from the suspension profile 15 in transverse direction towards the rear or back surface of panel 11. In the designs shown in figures 1-5, the panel abutment 27 provides a distance between the construction attachment flange 36 and the rear surface 25 of the panel 11.

[0048] In this embodiment, the suspension profile 15 comprises a groove 20 as part of the snap-fit attachment provision that is provided on the suspension profile 15. This groove 20 furthermore extends in longitudinal direction along suspension profile 15, and is thus referred to as longitudinal panel attachment groove 20.

[0049] In this embodiment, panel 11 comprises an attachment rail 21 that is designed to snap-fit into the longitudinal panel attachment groove 20. The attachment rail of this embodiment may also be described as a flange that extends away, in particular perpendicular away, in transverse direction, from the back surface 25 of panel 11. It furthermore extends in longitudinal direction along the back surface of panel 11.

[0050] In this embodiment, the attachment rail 21 is provided with a snap-fit ledge 29. This snap-fit ledge 29 here extends longitudinally on attachment rail 21. The longitudinal panel attachment groove 20 is furthermore provided internally with a groove snap-fit ledge 30 which is designed to cooperate with the snap-fit ledge 29 on the attachment rail 21 to snap-fit together when attachment rail 21 is pressed into longitudinal panel attachment groove 20. Groove snap-fit ledge 30 in fact reduced the width of the longitudinal panel attachment groove 20 near the groove opening. Furthermore, it is designed and positioned to provide, in cross-section, a barb, preventing removal of the attachment rail 21 in a direction more or less normal to the panel back surface 25. To that end, One or both walls of the longitudinal panel attachment groove 20 may be a little resilient. In this way, snapping the attachment rail 21 into the longitudinal panel attachment groove 20 while allowing the snap-fit ledge 29 to pass the groove snap-fit ledge 30 is possible. Here, the opening width of the longitudinal panel attachment groove 20 is a little less than the thickness of the attachment rail behind the snap-fit ledge.

[0051] Here, the opening of the longitudinal panel attachment groove 20 is flush or behind the panel abutment 27. The dimensions and distances of the snap-fit ledge 29, in particular its abutment surface, and the panel back surface 25 are selected with respect to the distance between the groove snap-fit ledge, in particular its abutment surface, and the panel abutment 27 to allow snap fitting with the panel abutment firmly abutting the panel abutment 27.

[0052] In this embodiment of the attachment rail 21, it is provided with a positioning ledge 28 that can best be seen in the cross sections of figures 3-5. At the location of this positioning ledge 28, the thickness of the attachment rail 21 is less than at the location of the snap-fit ledge 29. This provision allows the attachment rail 21 to be held in longitudinal panel attachment groove 20 temporarily. Thus, positioning ledge 28 snaps behind groove snap-fit ledge 30 first. The thinner part of the attachment rail 21 allows relatively easy removal of the panel 11. When the position can be fixed permanently, the panel 11 is pressed in the direction of the suspension profile 15 more firmly, such that snap-fit ledge 29 snaps behind groove snap-fit ledge 30.

[0053] In figure 3, an abutment ledge 23 is part of the upper surface of the upper wall of longitudinal panel attachment groove 20. It extends, however, not beyond ventilation channel 18 of the lower mounting beam 13 so that it does not interfere with or the block the ventilation channels 12.

[0054] When a soffit board mounting groove 19 is provided like in the embodiments of figures 4 and 5, the upper wall of longitudinal panel attachment groove 20 can interfere with the ventilation passages of lower mounting beam 13. To prevent this, an abutment ledge 23 is provided between the attachment surface 26 of the construction attachment flange 36 and the ventilation passage of lower mounting beam 13. This abutment ledge 23 provides an abutment of the suspension profile 15 in a direction cross to the attachment surface 26, more in particular perpendicular.

[0055] Thus, ventilation channel 18 of lower mounting beam 13 opens behind abutment ledge 23, when viewed . Thus, continuous ventilation channels are provided. These ventilation channels at one end open at the upper edge of the panel 11. The other ends of the ventilation channels open behind the panel 11 and above soffit board 10.

[0056] The figures 3-5 shows different embodiments of the suspension profile that may be used in different building or construction types. In figure 3, the panel assembly is used in a building having no or almost no soffit or oversail. Suspension profile 15 this extends along and near the outer wall 6. In this embodiment, care is taken to provide a small spacing between the suspension profile 15 and outer wall 6 to provide a ventilation slit.

[0057] In figure 4, an example of a panel assembly 1 is shown with can be used for relatively thin soffit boards 10. In figure 5, an embodiment is shown for relatively thick soffit boards 10.

[0058] For easy mounting, the rear surface 25 of panel 11 is provided with a recess 22 for providing space for mounting provisions 35 for the suspension profile 15. Here space is provided for the heads of screws 35.

[0059] As explained, the panel attachment assembly 1 comprises the suspension profile 15, from which the panel 11, in the attached condition, is actually hung. This suspension profile 15 is relatively rigid, providing a defined basis for attaching panel 11. Suspension profile 15 can be from metal of polymer material. In one embodiment the suspension profile 15 is for instance made of metal, for instance aluminium or stainless steel. Alternatively, the suspension profile may comprise polymer material, or fibre-reinforced polymer. In the current embodiment, the suspension profile is polymer extrusion profile. The object of a rigid profile such as suspension profile 15 is for providing a properly level basis to which panel 11 can be attached level.

[0060] The suspension assembly 1 with suspension profile 15 makes it possible to easily hang a panel such that positioning is possible. First, the attachment rail 21 is snapped into the attachment groove 20 slightly, with positioning snap ledge 28 snapping behind the groove snap ledge 30. Panel 11 can still be removed from the suspension profile 15 when desired. When the position is right, the position of panel 11 can be fixated by pushing panel 11 with its attachment rail 21 further into the panel attachment groove 20 such that the attachment rail snaps completely into that groove 20, now with groove snap ledge 30 hooking behind attachment rail snap-fit ledge 29. As the rail at that position is thicker than at the location of the positioning snap ledge 28, removal is no longer possible in the direction cross to the longitudinal direction of the panel 11.

[0061] The upper mounting beam 16 and the lower mounting beam 13 may be simple wooden beams having for instance rectangular, transverse slits. Alternatively, these beams may be from a polymer material. The may comprise a foamed core.

[0062] It will be clear that the above description is included to illustrate the working of preferred embodiments, and not to limit the scope of the invention. Starting from the above explanation many variations that fall within the spirit and scope of the present invention will be evident to an expert.
