Claims

- 2. A damper 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) having a biasing means (11), that, upon an applying an 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 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) including a checking mechanism (22) for engaging and checking said inward force (11-B) and holding said rod (16) and door (62) towards any opened position (62-B); said assembly (50) comprisingan extensible bracket (50-A) housing a fixated bracket (50-B) and operator (54) controlling a counter biasing means (55) comprising normal operation as substantially inactive unless, said assembly (50) detects that said inward force (11-B) has exceeded said device (10), including the excessive inward force (11-B) caused when the rod (16) held in an extended position (16-B) with an engaged checking mechanism (22) while the door (62) is forced towards the closed position (62-A) without first disengaging said mechanism (22); wherein said assembly (50) responsively compensates said excessive inward force (11-B) by conversely providing an increasingly actuated biasing means (55-B) for causing said door (62) towards said closed portion (63-A), and, a decreasingly actuated biasing means (55-A) for causing said door (62) again towards said opened position (62-B).
- 3. The damper assembly (50) adapted to a reciprocative device (10) and contingent object (62) of claim 2, whereinsaid operator (54) is selected from the group of a spring operator means (54-A), a fluid operator means (54-B), and a cog operator means (54-C).
- 4. The damper assembly (50) adapted to a reciprocative device (10) and contingent object (62) of claim 2, whereinsaid fixated bracket (50-B) further provide a lock means (58) to cancel said counter biasing means (55) and permitting normal operation for said device (10) as though not equipped with said assembly (50).
- 5. The damper assembly (50) adapted to a reciprocative device (10) and contingent object (62) of claim 2, whereinsaid fixated bracket (54-B) comprising an offsetting fastener means (52) permitting universalness for a singular assembly (50) adaptable to left and right hinging doors (62).
- 6. An improved reciprocative door closer device (10) for controlling a contingent door (62); said device (10) normally operating to substantially cause said door (62) towards a closed door position (62-A) including a piston rod (16) which functions reciprocatively from within a piston body (12) having 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 forces (11-B) and holding said rod (16) and door (62) towards arty opened position (62-B); said device (10) further including a spring assembly (30) comprising a hinge bracket (50-A) joined to a fixated bracket (50-B) and a spring means (54) opting a counter biasing means (55) to dampen, protect, and compensate said device from an excessive inward force (11-B) comprisingsaid counter biasing means (55) providing normal operation to actuate substantial zero force as to not positively contribute affecting said biasing means (11) either for any increasingly outward force (11-A) towards the opened position (62-B), or, for any decreasingly inward force (11-B) towards the closed position (62-B), unless, said assembly (50) detects that said inward force (11-B) has exceeded 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 and (16), by then opting said ligamentous movement (55) to include as 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 return said device (10) and door (62) towards any normal operation.
