Patent ID: 8745824

Claim:
A hinge device mountable on a first element, such as a door frame, and on a second element, such as a door, to enable pivoting of the two elements relative to each other, the hinge device comprising: a first part, which is attachable to the first element, and a second part, which is attachable to the second element, wherein, the first part and the second part are rigidly connected to each other, the first part includes, a tubular first housing defining a first hinge axis, two balls being located within opposite ends of the first housing, an axially displaceable locking member arranged axially inwardly of each ball, a compression spring arranged between and cooperating with each ball and the associated locking member, and an eccentric located between the two locking members and cooperating therewith, and the second part includes, a tubular second housing defining a second hinge axis parallel to the first hinge axis, two balls being located within opposite ends of the second housing, an axially displaceable locking member arranged axially inwardly of each ball, a compression spring arranged between and cooperating with each ball and the associated locking member, and an eccentric located between the two locking members and cooperating therewith, each eccentric is rotatable about an axis transverse to the first hinge axis and the second hinge axis, each eccentric being rotatable between an initial position and an active position, the initial position being a position in which the two associated locking members are located in an axially inner position so that the springs project at least part of the balls beyond the housing the active position being a position in which the two associated locking members are located in an axially outer position so that the locking members abut against the balls and project at least part of the balls beyond the housing, and when the eccentric is in the initial position, the balls are retractable into the housing, and when the eccentric is in the active position, the balls are not retractable into the housing.
