ABSTRACT:
The frame is provided with several, at least partially straight sides and outwardly projecting locking elements formed on all sides, which are of such a complementary configuration that each side of a frame can be coupled with one side of another frame through the locking elements and several frames can be united in one plane to form a frame panel. The frame bodies can be injection molded from plastic in one piece with the locking elements. In another frame embodiment, each frame has a base plate and a frame overlay which can be fixed on the latter by fastening means, the outwardly projecting locking elements being formed on the outside margin of the base plate. The locking elements have preferably identical profiles and interspacing on all frames, so that frames of different frame sizes can be combined without problems.
