Fastening device for flat components, especially solar modules, to be arranged on a framework

1. A fastening assembly for arranging frameless flat components on a framework, comprising:

a first profile mounting rail and a second profile mounting rail that are spaced apart from one another and that are to be arranged in a horizontal and parallel orientation on the framework and on each of which a first frameless flat component is affixable at respective areas of mutually opposing edges of the first frameless flat component;

for each one frameless flat component of said arranged frameless flat components, profile elements arranged on a bottom of said one frameless flat component, each one of said profile elements including a retaining rib at a lateral edge; and

a retaining element distinct from the first and second profile mounting rails and that has a first fastening segment for fastening the retaining element to a first fastening area of one of said first and second profile mounting rails, and that has a second fastening segment for fastening adjacent frameless flat components, the second fastening segment having two retaining segments,

wherein said retaining element is generally T-shaped having a longitudinal leg forming the first fastening segment and a transverse leg forming the second fastening segment, said transverse leg extending toward each of the adjacent frameless flat components while the adjacent frameless flat components are installed to overlap the respective retaining rib of each of the adjacent frameless flat components;

wherein said one of said first and second profile mounting rails includes an undercut groove forming a portion of said first fastening area; and

wherein said first fastening segment of said retaining element has a hook segment movable within the undercut groove during installation and by which said retaining element is retained in said undercut groove while in the assembled position.

2. A fastening device assembly according to claim 1 , wherein said profile elements are profile rails or profile connectors that join the profile rails at corners thereof.

3. A fastening device assembly according to claim 1 , wherein:

said groove is embodied as a double undercut T-groove; and

said hook segment is embodied in a corresponding T shape matching a shape of the T-groove.

4. A fastening assembly according to claim 1 , further comprising a stop provided on said retaining element opposing an adjacent one of said profile elements when in the assembled position.

5. A fastening device assembly according to claim 1 , wherein, provided on said first profile mounting rail is a rib-shaped stop for abutting one of said profile elements at a lower edge portion of one of said frameless flat components.

6. A fastening assembly according to claim 1 , wherein one of said first and second profile mounting rails has a second fastening area in a form of a generally C-shaped receiving groove that is open toward an edge of a received frameless flat component and which engages a rib of a profile element arranged on a bottom of said received frameless flat component, wherein said engaged rib is overlapped by a leg of said receiving groove.

7. A fastening assembly according to claim 6 , wherein said first and said second fastening areas are embodied on each of said first and second profile mounting rails.

8. A fastening assembly according to claim 6 , wherein, in the assembled position, said first fastening area is disposed higher than said second fastening area.

9. A fastening assembly according to claim 1 , wherein, for a first frameless flat component of said arranged frameless flat components a sealing element is provided at a first profile element of said profile elements and embodied as a profile rail extending horizontally, said sealing element continuing in said first profile, element, and against which, in the assembled position, an edge of a second frameless flat component of said arranged frameless flat components is arranged therebeneath.

10. A fastening assembly according to claim 1 , further comprising a profile component that extends longitudinally relative to the assembled position and that runs beneath a transition gap between two adjacent frameless flat components being provided between two mutually opposing ones of said profile elements.

11. A fastening assembly according to claim 9 , wherein each one of said profile elements further includes a laterally open receiving or clamping segment for receiving a clamping segment of said sealing element.

12. A fastening assembly according to claim 1 , wherein each one of said profile elements further includes a support surface having a toothed or scored surface structure.

13. A fastening assembly according to claim 1 , wherein at least one of said profile elements includes at least one hollow chamber in which a stiffening element is arranged.

14. A component group that is arranged on a framework and in which a plurality of adjacently arranged components are combined using a fastening assembly according to claim 1 to create a compound unit.

15. A component group according to claim 14 , wherein an anti-theft element is provided merely on said exterior components.

16. A fastening assembly according to claim 1 , wherein the retaining element is monolithically formed.
