female groove 12 is compatible with themale locking profile 1 in such an extent that saidmale locking profile 1 can be secured in saidfemale groove 12 for creating a tongue-and-groove joint 15 that locks twoadjacent roof panels 100 to each other. There is no need for using fasteners, such as screws, or glue etc. in the tongue-and-groove joint 15. - The structure of at least one of the
male locking profile 1 and thefemale locking profile 2 is elastically flexible so that themale extensions 6 can be pressed or forced through theopen bottom 14 of the female locking profile into thefemale groove 12, and then elastic forces press the locking profiles against each other. Said flexibility is preferably based on the properties of the sheet of material. - Following creating the tongue-and-groove joint 15 where two roof panels join to each other, the
fasteners 10 are inside a "tunnel" created by theclosed top 13 of the female locking profile and themale extensions 6 of the male locking profile. Said "tunnel" creates an airway through which air can flow. This flow flushes contacting points of thebottom 8 and thefasteners 10, reduces dampness and thus reduces risk of corrosion between the bottom and the fasteners. - The locking profiles 1, 2 attached to each other may serve as an attachment point to various fasteners, brackets, clamps 22 etc. by means of which roof safety products or other products may be coupled to a roof. The roof safety product may be e.g. a snow guard, roof ladders and bridges. The roof safety products may be installed with a crimped connection, which is allowed by the shape of the locking profile. Crimped connection does not need any holes to be drilled thus avoiding any addition of leakage points to the roof panel. Other products may be e.g. a solar panel.

Figure 3a is a schematic view of a female locking profile, andFigure 3b is a schematic view of a male locking profile. - In one embodiment, the
female locking profile 2 is constructed from straight sections that are bent into a stepwise curvature. In other words, the cross-sectional profile XF of the female locking profile comprises straight sections that creates a stepwise curvature. This stepwise curvature comprises a lockingshape 23 in a form of at least one bend, shown inFigure 3a . The lockingshape 23 provides a laterally projecting part in the cross-sectional profile XF into which themale locking profile 1 can lock with its corresponding lateralmale locking shape 24, shown inFigure 3b . - In one embodiment, the bend is in range of 90°- 130°.
- In one embodiment, one of the
female extensions 11 comprises the lockingshape 23, but another female extension is devoid thereof. In one embodiment, thefemale extensions 11 have symmetrical profiles. In one embodiment, each of the twofemale extensions 11 comprises the locking shape. - In one embodiment, the
male locking profile 1 is constructed from straight sections that are bent into a stepwise curvature, i.e. the cross-sectional profile XM of the male locking profile comprises straight sections that creates a stepwise curvature, such as shown infigure 3b . This stepwise curvature comprises amale locking shape 24 in a form of at least one bend. This shape provides a laterally projecting part in the cross-sectional profile XM that can lock with its corresponding lateralfemale locking shape 23, for instance as shown inFigure 3a . - In one embodiment, the bend is in range of 90°- 130°.
- In one embodiment, one of the
male extensions 6 comprises themale locking shape 24, but another male extension is devoid thereof. In one embodiment, themale extensions 6 have symmetrical profiles. In one embodiment, each of the twomale extensions 6 comprises the male locking shape. The embodiments shown inFigures 3a and 3b have five straight sections in their cross-sectional profiles. However, the number of the straight sections may be less or more than five. - In one embodiment, the
female locking profile 2 additionally comprises at least one outwardly directed guidingsurface 25. The embodiment shown inFigure 3a comprises guidingsurfaces 25 on both sides of the profile. These surfaces help with fitting themale locking profile 1 in thefemale locking profile 2. -
Figure 4 is a schematic view of another female locking profile. In one embodiment, the cross-sectional profile of the locking profile comprises a circular arch. This kind of locking profile may be themale locking profile 1 orfemale locking profile 2, or they both. -
Figure 4 is showing an embodiment of thefemale locking profile 2 where the cross-sectional profile XF is completely constructed from an arch. Said arch has a constant radius, but this is not always necessary. In other words, the arch may also comprise a section having different radius than another section of said arch. - In one embodiment, the cross-sectional profile of the locking profile comprises at least one arched section and at least one straight section. In one embodiment, the cross-sectional profile of the locking profile comprises alternating arched and straight sections.
- In one embodiment, such as shown in
Figures 1 and2 , the cross-sectional profile XF of female locking profile has a same profile as themale locking profile 1. However, this is not necessary. The profiles may differ much, as long as they can engage for creating the tongue-and-groove joint 15. For example, a female locking profile having an arched profile may engage with a male locking profile constructed from straight sections bent into a stepwise curvature. -
Figure 5 is a schematic view of another roof panel. In an embodiment, at least oneend 17 of the panel zone extends past the ends of the locking profiles and creates anextension strip 18. In an embodiment, both ends of the panel zone are provided with theextension strip 18. - This
extension strip 18 can be bend towards the underside UN or the upper side UP of theroof panel 100, and then left in a bend position. Theextension strip 18 may then provide shielding or screening sometimes needed at the end of the roof panel when the roof panel end is installed at the ridge of the roof. Theextension strip 18 allows for ventilation of roof structure underneath theroof panel 100 and blocks e.g. leaves and rain to enter the roof structure from the gap between the roof panel and the ridge of the roof. - In an embodiment, the
extension strip 18 comprises weak point (s) or weak line(s) 19 that help(s) the bending thereof to desired position. In an embodiment, there are multiple lines weakened by the weak point(s) or weak line(s) 19 so that multiple bends can be made easily in the extension strip. Theextension strip 18 may also comprise openings to allow air to reach the roof structure beneath theroof panel 100 for ventilation purposes. - The dimensions of the extension strip depend on e.g. heights of the locking profiles and the width of the panel zone.
- It is to be noted, that the
extension strip 18 does not necessitate presence of themale locking profile 1 and thefemale locking profile 2 described in this description. In other words, theextension strip 18 may be present in roof panels that comprises alternative locking profiles. - In an embodiment, at least one end of the
female locking profile 2 comprises anextension flap 20 that can be bent to close said end of thefemale locking profile 2. Theextension flap 20 is preferably of the same sheet of material as the female locking profile. - In
Figure 5 theextension flap 20 has been bent on the open end of the female locking profile. - The invention is not limited solely to the embodiments described above, but instead many variations are possible within the scope of the inventive concept defined by the claims below. Within the scope of the inventive concept the attributes of different embodiments and applications can be used in conjunction with or replace the attributes of another embodiment or application.
