Blocks supporting device with rotatable frame

摘要

The support consists of a base with sheet metal brackets (3) for a pivoting frame (4) which has its sides towards the brackets and is equipped with pivot pins (10) and stops (11) to engage with slots (5) in the brackets. Each slot has a first inclined section (5.1) which is wider than the diameter of a pivot pin (10), opens onto the bracket edge and is designed to receive a stop (11). A second section (5.2) of the slot is narrower than the first and extends downwards from its lower end, while a third section (5.3) extends downwards from the second and receives the pivot pin. A separate slot (7) in the bracket receives a locking screw (12).
