Abstract
Device for limiting the opening angle of doors, of the type comprising a chain, attached by an end to a shield that is fixed to the door frame and provided at the opposite end with an anchoring element capable of locking in an elongated slot provided in a body that is fixed to the movable door leaf, essentially characterized in that inside this body is mounted transversely a piece, capable of undergoing certain displacements in this direction and elastically driven to adopt a certain limit position, whose part forms an inclined plane arranged to develop a slip effect in cooperation with the anchor element referred to, allowing the passage thereof towards the end of the slot, and totally preventing the inverse movement, that is, preventing the disassembly, unless that transverse displacement of said piece is caused, acting on its extremity, which protrudes externally, and overcoming the resistance of the expressed coil spring.
