Metal joint e.g. for fail safe connection of multiple components in umbrellas, connects to rail components due to its material and its connection arrangement becomes shatterproof with components having diverse materials

摘要

The metal joint screen connects to rail components due to its material and its connection arrangement becomes shatterproof. The rail components have diverse materials allowing rivets or pins to be inserted. The rail is pressed into the metal joint and into place. The flexibility of the rail is limited within a defined range such that together, a stable connection develops. During extreme loading of the rail only some deformations permits, resulting from the natural flexibility of the rail component materials.
