One end of the lock barrel limiting push rod projects outside the card lock casing in order to selectively lock or release the lock barrel. When a card passes through the card-inserting groove to push the movable pressing unit to release the lock barrel limiting push rod, the lock barrel limited push is moved by the elasticity of the elastic element in order to release the lock barrel. | 07-08-2010 |
20110265531 | THEFT DETERRENT LOCKING SYSTEM - A cylindrical lock assembly has a locking core which separates into two portions when the locking core is struck along or across its axis. A reinforced barrier is positioned near a break zone between two portions of the locking core to promote separation at the break zone. The lock housing contains the locking core for movement between locked and unlocked positions. An optional reinforced tumbler prevents unauthorized removal of the locking core from the lock housing. The housing includes an optional reinforced section to inhibit unauthorized removal of the locking core from the lock housing. The lock assembly may be used in retrofit and new installations | 11-03-2011 |
20120103034 | Lock for locking a movable member to fixed member - A lock for locking a movable member to a fixed member, wherein the movable member has a recess, and wherein the fixed member has a threaded through bore. The lock includes a head, a stem, first locking apparatus, and an optional second locking apparatus. The head is for selective rotational resting in the recess in the movable member. The stem selectively movably depends from the head and is for selectively engaging in the threaded through bore in the fixed member. The first locking apparatus selectively prevents rotation of the head relative to the stem to thereby prevent rotation of the stem and withdrawal thereof from the threaded through bore in the fixed member to thereby selectively prevent removal of the lock from the fixed member. The second locking apparatus depends operatively from the stem, is operatively connected to the first locking apparatus, and is for selectively preventing retraction of the stem from the threaded through bore in the fixed member to thereby further selectively prevent removal of the lock from the fixed member. | 05-03-2012 |

The key has a helical blade capable of being inserted into the helical keyway to access the first pin, so as to switch the tumbler unit to permit the relative rotation between the cylindrical core and the housing. | 11-19-2015 |
20150345177 | ELIMINATING MAXIMUM ADJACENT CUT SPECIFICATION RESTRICTIONS FOR TELESCOPING PINS - A key device ( | 12-03-2015 |
20160032618 | CYLINDER LOCK INCLUDING MULTIPLE COOPERATING SIDEBARS FOR CONTROLLING THE LOCK - A cylinder lock includes a side bar assembly comprising a binding bar and a testing bar and code pins, each comprising a key projection, a code hole, and binding features. Partial rotation of the cylinder causes the binding bar to engage the binding features of the code pins to prevent axial movement of the pins. If the code holes of the code pins are aligned with code points of the testing bar, the testing bar is able to move inwardly with the binding bar and out of the slot so as to permit the cylinder to rotate within the bore. If one or more code holes is not aligned with a code point of the testing bar, the code point will contact the body of the code pin and thereby be prevented from moving radially inwardly out of a locking slot, thus blocking rotation of the cylinder. | 02-04-2016 |
