ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an angle bracket.
BACKGROUND INFORMATION
Many variants of angle brackets are already known, e.g., from the publication “Bosch, Flexible Automation, Basic Mechanical Elements”, volume 1996/97, pages 3-1 through 3-25.
To form partitions or safety walls, which are supposed to protect a hazardous area from unauthorized entry or access, the known angle brackets are mounted on supporting sections to attach framework constructions in the form of safety screens or safety panels, for example, on these supporting sections. In this regard, known angle brackets have the disadvantage of relatively low stability. Notching effects at the transition point of the two legs of an angle bracket allow only relatively lightweight framework constructions to be attached.
SUMMARY OF THE INVENTION
An angle bracket according to the present invention has the advantage of an especially high stability, so that relatively heavy framework constructions can also be secured safely and reliably to supporting sections. The supporting sections can therefore be positioned at greater distances from one another. This saves material costs and assembly costs for the partitions.
The angle bracket according to the present invention allows the framework constructions to be connectable to the supporting sections at variable distances and in almost any angular positions without making the construction and thus the manufacture of the mounting bracket or its assembly more difficult in comparison with known design variants. The angle bracket can also be designed to be compatible with known design variants, thus covering a wide range of applications.
According to the angle bracket of the present invention, centering devices are formed only on the first of the two legs of the angle bracket and engage with play in a longitudinal groove on the supporting sections. These centering devices achieve the result that the angle bracket can be arranged so that the angle bracket is centered and twisting is prevented, allowing displaceability in the direction of the longitudinal groove. In addition, the angle bracket according to the present invention includes section bars that can be arranged on both the inside and outside of the second leg. A further advantage of the angle bracket according to the present invention is that it can be manufactured especially inexpensively by a die-casting method.
