Ricardo Alonso, 111 S. Perry St., Denver, CO 80219 USA Pat. Pend. No.: Exp. No. No. EE 2581 68 760 US Filed Date: 09-MAR-04
MAGNETISM TO CONTROL COMPRESSIVE FRICTION CHECKS FOR RODS INCLUDING THOSE OF DOOR CLOSERS 1. A cup (70) for causing a compressive friction check mechanism (22) to engage (22B) and disengage (22A), utilized to hold the linear biasing forces (11A) and (11B) of a reciprocating device (10) and any object (62) attached thereto, exemplified as a door closer (10) comprising at least one rod (16) which linearly reciprocates from within a body (12) housing a biasing means (11); said rod (16) loosely mounted with said check (22) through an aperture (26) housed within a structure (34) comprising opposed friction points (28A) and (28B) to compressively engage the extended rod (16B); said check (22) further providing a trigger (38) to lever said check (22), comprising a magnetic means (72) adapted to said check (22) and said device (10); whereby said magnet (72) optionally positions said check (22) onto said extended rod (16B) to engage (22B) and disengage (22A) compliant to said object (62). 2. A method for causing a compressive friction check mechanism (22) to engage (22B) and disengage (22A), utilized to hold the linear biasing forces (11A) and (11B) of a reciprocating device (10) and any object (62) attached thereto, exemplified as a door closer (10) comprising at least one rod (16) which linearly reciprocates from within a body (12) housing a biasing means (11); said rod (16) loosely mounted with said check (22) through an aperture (26) housed within a structure (34) comprising opposed friction points (28A) and (28B) to compressively engage the extended rod (16B), said check (22) further providing a trigger (38) to lever said check (22), said method adapting a magnetic means (72) to said check (22) and said device (10); whereby said magnet (72) optionally positions said check (22) onto said extended rod (16B) to engage (22B) and disengage (22A) compliant to said object (62). 3. A cup (72) for causing a compressive friction check mechanism (22) to disengage (22A) and engage (22B) the tensile of a rod (16) which maintains certain biasing forces (11A) and (11B) supporting any object (62) attached thereto; said rod (16) loosely mounted with the said check (22) through an aperture (26) housed within a structure (34) comprising opposed friction points (28A) and (28B) adapted to said rod (16); said check (22) further providing a trigger (38) to lever said check (22), comprising a magnetic means (72) adapted to said check (22); whereby said magnet (72) positions said check (22) to compressively engage (22A) and disengage (22B), for withstanding said forces (11A) and (11B) by utilizing the tinsel strength of said rod (16) compliant to said object (62). 4. A method for causing a compressive friction check mechanism (22) to disengage (22A) and engage (22B) the tensile of a rod (16) which maintains certain biasing forces (11A) and (11B) supporting any object (62) attached thereto; said rod (16) loosely mounted with said check (22) through an aperture (26) housed within a structure (34) comprising opposed friction points (28A) and (28B) adapted to said rod (16); said check (22) further providing a trigger (38) to lever said check (22), said method adapting a magnetic means (72) to said check (22); whereby said magnet (72) positions said check (22) to compressively engage (22A) and disengage (22B), for withstanding said forces (11A) and (11B) by utilizing the tinsel strength of said rod (16) compliant to said object (62).
