Framework for edge joints, has frame parts formed so that side piece of edge joints are immersed completely into two neighboring frame parts and edge joints are enclosed by frame parts from exterior of framework

摘要

The framework (1) has frame parts (2.2-2.4, 3.1-3.4), which are formed as so that the side piece of edge joints are immersed completely into two neighboring frame parts. The edge joints are enclosed by the frame parts from the exterior of the framework. The section of the frame part is a square section with an open corner and the open corner follows the final section. The final section is appropriated parallel to the open corner of the square profile with the neighboring final section. An independent claim is also included for the edge joints for a framework with a vertical frame part and a horizontal frame part, where the frame parts encompass through the sections.
