연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A lock system is provided having a lock housing and a lock barrel, a keeper shoulder, at least one full positioner shoulder, and a positioner shoulder having a U-shaped channel. A lock plug having a keyway and tumblers is received in the barrel for rotation between locked and unlocked positions. The tumblers include a key tumbler, a positioner tumbler and a keeper tumbler. The lock plug is rotatable between a first rotary position and a second rotary position. A control key is received into the keyway to retract the lock tumbler and partially retract the keeper tumbler. Removal of the lock plug from the lock barrel requires rotation of the lock plug from the first rotary position to the second rotary position and the presence of the control key within the lock plug when in the second rotary position.

The lock system of claim 1, wherein the tip extends to the outer end of the partial positioner shoulder, and wherein the tip is axially outward of the cutout face of the cutout portion. 3. The lock system of claim 1, wherein the cutout portion is configured to allow the positioner tumbler to rotate within the cutout portion between the tip of the partial positioner shoulder and an adjacent full positioner shoulder. 4. The lock system of claim 1, wherein said lock barrel includes a plurality of tumbler grooves extending axially therealong. 5. The lock system of claim 1, wherein the predetermined angle is 45 degrees. 6. The lock system of claim 1, wherein the keeper tumbler engages the keeper shoulder in the first rotary position and wherein the keeper tumbler is rotationally aligned with the channel in the second rotary position. 7. The lock system of claim 1, wherein the lock plug is configured so that it cannot be removed from the lock housing by the master key. 8. The lock system of claim 1, wherein the lock housing includes a cam which rotates between locked and unlocked positions to selectively retain the entry closure in a locked position. 9. The lock system of claim 1, wherein the tumblers comprise spring biased wafer tumblers, and wherein the lock plug includes a plurality of lock tumblers. 10. A lock system for an entry closure, comprising: a lock housing for mounting adjacent the entry closure and including a cylindrically-shaped lock barrel with at least one tumbler groove extending axially therealong, a keeper shoulder disposed proximate an inner portion of said lock barrel, at least one full positioner shoulder, and a positioner shoulder having a substantially U-shaped channel;a cylindrically-shaped lock plug shaped for close reception in the lock barrel for rotation between locked and unlocked positions, and including an axially extending keyway and a plurality of radially shiftable outwardly biased tumblers comprising at least one key actuated lock tumbler, a positioner tumbler disposed adjacent to an outer portion of the lock plug, and a keeper tumbler disposed adjacent to an inner portion of the lock plug;a control key having a shank portion shaped for close reception in the keyway with a plurality of bits configured to retract the lock tumbler and the keeper tumbler when inserted into the keyway;a master key having a shank portion shaped for close reception in the keyway with a plurality of bits configured to fully retract both the lock tumbler and the positioner tumbler, and not retract the keeper tumbler when inserted into the keyway;a customer key having a shank portion shaped for close reception in said keyway with a plurality of bits configured to fully retract both the positioner tumbler and the lock tumbler, and not retract the keeper tumbler when inserted into the keyway; anda partial positioner shoulder including and extending from an inner end disposed proximate the keeper shoulder to an outer end disposed proximate the outer portion of the lock plug, wherein the outer end includes a cutout portion;whereby removal of the lock plug from the lock barrel requires rotation of the lock plug from the first rotary position to the second rotary position wherein the keeper tumbler is axially aligned with the U-shaped channel and the presence of the control key within the keyway and wherein rotation of the lock plug from the first rotary position to the second rotary position is obtained by insertion of the control key within the keyway and rotation of the lock plug from the first rotary position to the second rotary position, wherein the positioner tumbler is rotated into the cutout portion, thereby permitting axial shifting of the lock plug out of the lock barrel for repair or replacement. 11. The lock system of claim 10, wherein the partial positioner shoulder includes a tip that extends to the outer end of the partial positioner shoulder, wherein the tip is axially outward of a cutout face of the cutout portion. 12. The lock system of claim 10, wherein the cutout portion is configured to allow the positioner tumbler to rotate within the cutout portion between the tip of the partial positioner shoulder and an adjacent full positioner shoulder. 13. The lock system of claim 10, wherein the keeper tumbler is positioned for abutting contact with the keeper shoulder in the first rotary position and wherein the keeper tumbler is rotationally aligned with the U-shaped channel in the second rotary position. 14. A lock system for vehicle entry closures, comprising: a lock housing for mounting adjacent the entry closure and including a cylindrically-shaped lock barrel with a plurality of tumbler grooves extending axially therealong, a keeper shoulder disposed proximate an inner portion of the lock barrel, at least one full positioner shoulder and a positioner shoulder having a substantially U-shaped channel, the tumbler groove being disposed between and separating the full positioner shoulder from the positioner shoulder having the U-shaped channel;a cylindrically-shaped lock plug shaped for close reception in the lock barrel for rotation between locked and unlocked positions, and including an axially extending keyway and a plurality of radially shiftable outwardly biased tumblers comprising at least one key actuated lock tumbler, a positioner tumbler disposed adjacent to an outer portion of said lock plug, and a keeper tumbler disposed adjacent to an inner portion of said lock plug, the lock plug having a first rotary position in the lock barrel wherein the keeper tumbler is positioned for abutting contact with the keeper shoulder and a second rotary position wherein the keeper tumbler is axially aligned with the U-shaped channel; anda control key having a shank portion shaped for close reception in the keyway with a plurality of bits configured to retract the lock tumbler and the keeper tumbler;a master key having a shank portion shaped for close reception in said keyway with a plurality of bits configured to retract only the lock tumbler and the positioner tumbler; anda customer key having a shank portion shaped for close reception in the keyway with a plurality of bits configured to retract only the positioner tumbler and the lock tumbler;the lock barrel further comprising a partial positioner shoulder including and extending from an inner end located proximate the keeper shoulder to an outer end including a cutout portion, the partial positioner shoulder further including a tip that extends to the outer end of the partial positioner shoulder, wherein the tip is axially outward of a cutout face of the cutout portion, and wherein the cutout portion is configured to allow the positioner tumbler to rotate within the cutout portion between the tip of the partial positioner shoulder and an adjacent full positioner shoulder when the control key is inserted within the keyway;whereby removal of the lock plug from the lock barrel requires rotation of the lock plug from the first rotary position to the second rotary position wherein the keeper tumbler is axially aligned with the U-shaped channel and the presence of the control key within the keyway and wherein rotation of the lock plug from the first rotary position to the second rotary position is obtained by insertion of the control key within the keyway and rotation of the lock plug from the first rotary position to the second rotary position, wherein the positioner tumbler is rotated into the cutout portion, thereby permitting axial shifting of the lock plug out of the lock barrel for repair or replacement.
