with locking means E05B63/22}) - Y10T 292/1014: Operating means - E05C: BOLTS OR FASTENING DEVICES FOR WINGS, SPECIALLY FOR DOORS OR WINDOWS (latching means for sideboard or tailgate structures for vehicles B62D, {B62D33/02}; fastening devices for constructional or engineering elements E04, F16B; locks, fastening devices structurally or operatively combined or having significant cooperation with locks E05B; means for operating or controlling wing fasteners in conjunction with mechanisms for moving the wing E05F) - Y10T: TECHNICAL SUBJECTS COVERED BY FORMER US CLASSIFICATION ## Abstract A catch member within one of a movable door or fixed jamb head or frame for the door, cooperates with a probe member within the other one of the movable door or fixed jamb head or frame for the door in closing and opening the door via attracting forces between an embedded rare earth magnet in one with respect to a steel pin in the other in a construction wherein both the magnet and the pin are hidden from view when the door is open or closed—in presenting a more attractive appearance in high-end interior door constructions and high-end fashionable cabinetry installations. ## Claims ### Claim 1 The combination comprising: a movable door; a fixed jamb head or frame for said door; an orientingly facing catch member within one of said door and said fixed jamb head or frame; an oppositely orientingly facing probe member within said other of said door and said fixed jam head or frame; with the catch member having an open first end, a closed second end, and an embedded rare earth magnet affixed inwardly of said closed second end; with the probe member having a steel pin within a nonmagnetic shell having an open first end and a closed second end; and wherein the probe member pin is sized to move freely within the nonmagnetic shell into the catch member under the attracting forces of the embedded rare earth magnet. ### Claim 2 (depends on 1) The combination of claim 1 wherein the movable door constitutes an interior room door, wherein the catch member is embedded within an underside of said jamb head or frame for said door, and wherein the probe member is embedded within a top surface of said door. ### Claim 3 (depends on 1) The combination of claim 1 wherein the movable door constitutes a cabinet door, wherein the catch member is embedded within an underside of said jamb or frame for said door, and wherein the probe member is embedded within a top surface of said door. ### Claim 4 (depends on 1) The combination of claim 1 wherein a top surface of the steel pin is of a downwardly tapering, rounded dome shape. ### Claim 5 (depends on 4) The combination of claim 4 wherein the downward tapering of the rounded dome shape of the steel pin extends on either side of the steel pin. ### Claim 6 (depends on 1) The combination of claim 1, wherein a top surface of the steel pin is of a downwardly tapering, rounded dome shape, wherein the downward tapering of the rounded dome shape of the steel pin extends on either side of the steel pin, and wherein pushing said movable door to align the steel pin with the embedded rare earth magnet of the catch member secures said movable door closed and wherein pulling said movable door to align a tapering portion of the steel pin with the embedded rare earth magnet releases said movable door to open. ### Claim 7 (depends on 6) The combination of claim 6 wherein the catch member is sized to seat within an aperture drilled within an underside of the jamb head or frame for said door and wherein the probe member is sized to seat within an aperture drilled within said top surface of said door. ### Claim 8 (depends on 1) The combination of claim 1 wherein the embedded rare earth magnet is composed of a neodymium alloy. ### Claim 9 (depends on 8) The combination of claim 8 wherein the probe member includes a steel pin of cylindrical configuration of ⅜ inch diameter sized to fit with a clearance of ⅛ inch within said nonmagnetic shell. ### Claim 10 (depends on 9) The combination of claim 9 wherein the width of the embedded rare earth magnet is ⅛ inch greater than the diameter of the steel pin. ### Claim 11 (depends on 1) The combination of claim 1 wherein a top surface of the steel pin is of a downwardly tapering, dome shape with a flat portion tip. ### Claim 12 (depends on 11) The combination of claim 11 wherein the tapering of the dome shape of the steel pin extends on either side of the flat portion of the steel pin. ### Claim 13 (depends on 1) The combination of claim 1, wherein a top surface of the steel pin is of a downwardly tapering dome shape, wherein the tapering of the dome shape of the steel pin extends on either side of a flat portion of the steel pin, and wherein pushing said movable door to align the flat portion of the steel pin with the embedded rare earth magnet of the catch member secures said movable door closed and wherein pulling said movable door to align a tapering portion of the steel pin with the embedded rare earth magnet releases said movable door to open. ### Claim 14 (depends on 13) The combination of claim 13 wherein the catch member is sized to seat within an aperture drilled within an underside of the jamb head or frame for said door and wherein the probe member is sized to seat within an aperture drilled within said top surface of said door. ### Claim 15 (depends on 14) The combination of claim 14 wherein the probe member includes a steel pin of cylindrical configuration of ⅜ inch diameter sized to fit with a clearance of ⅛ inch within said nonmagnetic shell. ### Claim 16 (depends on 15) The combination of claim 15 wherein the width of the embedded rare earth magnet is ⅛ inch greater than the diameter of the steel pin.
