ARM ACTUATOR FOR PIVOTING A BUILDING ELEMENT

An arm actuator (1) comprising a suspension arm (4) configured to move a building element (2) and a push-pull chain (5) configured to be operably connected to said suspension arm (4). The push-pull chain (5) can bend freely in a first direction (D1) when subjected to a first force (F1), and bend onl...

Beschreibung
Zusammenfassung:	An arm actuator (1) comprising a suspension arm (4) configured to move a building element (2) and a push-pull chain (5) configured to be operably connected to said suspension arm (4). The push-pull chain (5) can bend freely in a first direction (D1) when subjected to a first force (F1), and bend only to a limited extent in a second direction (D2) when subjected to a second force (F2), said second direction (D2) being opposite to said first direction (D1). A chain support arm (6) is provided, which pivots at least partially simultaneously with said suspension arm (4). The chain support arm (6) is configured to engage and prevent said push-pull chain (5) from bending, in said second direction (D2), past a first bending radius (Rl).
