Abstract:
A spring assembly (50) adapted to a reciprocative door closer device (10) and contingent door (62); said device (10) comprising normal operation to substantially cause said door (62) towards a closed door position (62-A); said device (10) including a piston rod (16) which functions reciprocatively from within a piston body (12) controlling a biasing means (11), that, upon an applying an external outward biasing force (11-A) comprising normally increasing actuation for causing said rod (16) and door (62) towards an opened position (62-B), said biasing means (11) acting to counter and control an inward biasing force (11-B) comprising normally decreasing actuation for again causing said rod (16) and door (62) towards the closed position (62-A) said device (10) further including a checking mechanism (22) for engaging and checking said inward force (11-B) and holding said rod (16) and door (62) towards an opened position (62-B); said assembly (50) comprisinga hinge bracket (50-A) joined to a fixated bracket (50-B) and a spring (54) means capable of a ligamentous movement (55) comprising normal operation as substantially inactive and not affecting said biasing means (11), either for any increasingly outward force (11-A) towards the closed position (62-A), or, for any decreasingly inward force (11-B) towards the opened position (62-B), unless, said assembly (50) detects said inward force (11-B) as exceeding said device (10) including the excessive inward force (11-B) caused when the rod (16) and door (62) are held in any opened position (62-B) with an engaged checking mechanism (22) and urged towards any closed position (62) without first disengaging said mechanism (22); wherein said assembly (50) responsively compensates said excessive inward force (11-B) conversely without cause to said rod (16), by then providing said ligamentous movement (55) to include am increasing actuation for causing said door (62) towards any closed position (62-A), and, a decreasing actuation for causing said door (62) again towards any opened position (62-B) to dampen, protect, and compensate from said excessive inward force (11-B) and return said device (10) and assembly (50) towards their normal operation.
