| 65 | Method for rekeying a rekeyable lock cylinder | US11984881 | 2007-11-23 | US07526935B2 | 2009-05-05 | Lien-Hsi Huang; Ping-Hung Hsieh |
| This invention is to provide a method for rekeying a rekeyable lock cylinder. The first step of entire rekeying process is to insert a first user key into a keyhole of a sliding block of a plug assembly and turn the first user key to rotate the plug assembly, then a thrust is added to the first user key to move the sliding block of the plug assembly, thereby disengaging a plurality of upper locking pieces and a plurality of lower locking pieces within a plurality of lower pin sets. Next, after pulling out the first user key from the keyhole, a second user key is inserted into the keyhole of the sliding block and turned to restore the sliding block as to reengage the upper locking pieces and the lower locking pieces. Finally, the second user key is pulled out to complete the entire rekeying process. Accordingly, the present invention may provide advantages of widely lowering rekeying cost and enhancing convenience in use, because lock replacement may be completed as soon as rekeying another user key only without replacing lock cylinder. | ||||||

| 73 | Locking device with a cylinder lock and a flat key | US91093 | 1998-06-11 | US6041631A | 2000-03-28 | Benno Vonlanthen |
| The cylinder lock comprises blocking tumblers which are guided parallel to the broad sides of the key channel. On the broad sides (13, 14) of the flat key (2) guide grooves (15, 16) are disposed which cooperate with carriers on the blocking tumblers. The grooves (15, 16) on the key (2) comprise several function regions, wherein a subregion (51) of the groove comprises an expanded groove width. The tumblers whose carriers engage these expanded groove regions (51) are equipped with additional positioning elements. This configuration prevents the unauthorized opening of a lock according to the invention with a key (2) with duplicated guide grooves (15, 16). | ||||||
| 74 | Key switch system for a vehicle | US446738 | 1995-12-21 | US5653131A | 1997-08-05 | Kazumi Shibata; Yoshiaki Hirakata |
| In a key switch system for a vehicle, a plurality of tumblers 6 and a pair of cylinder pins engaging tumbler engagement grooves 1.sub.2 in an outer cylinder 1 are radially slidably carried in an inner cylinder 2 which is rotatably carried within the outer cylinder 1. If a key K is correctly and deeply inserted into a key hole 2.sub.1, the tumblers 6 are disengaged from the tumbler engagement grooves 1.sub.2 by a code valley K.sub.1 of the key K, and the pair of cylinder pins 8 are disengaged from the tumbler engagement grooves 1.sub.2 by a tip end K.sub.2 of the key K, thereby permitting the rotation of the inner cylinder 2. If the key K is turned in a state in which it is not correctly and deeply inserted into the key hole 2.sub.1, the rotation is restricted by the engagement of the cylinder pins 8 having a high rigidity into the tumbler engagement grooves 1.sub.2, thereby preventing a damage to the tumblers 6. | ||||||
| 75 | Pivoting tumbler system | US48411 | 1987-05-11 | US4753091A | 1988-06-28 | Timothy Sheets |
| Pivotable tumblers mounted to a cylindrical plug prevent rotation of the plug unless a correct key in a keyway moves the tumblers to an unlocked position. If the tumblers extend too far into the keyway, pawls mounted in the body and acting on steps of the plug prevent rotation of the plug to an unlocked position. If the tumblers do not extend for enough into the keyway, the tumblers jam up against a reentrant shoulder of the body preventing the plug from reaching the unlocked position. A security keyway closure or door cams off a race in the body and closes the keyway with rotation of the plug. A slot in the key passes the door during operation. | ||||||

| A rotary cylinder lock with a lock cylinder rotatable in a casing, preferably a door handle housing of a motor vehicle, with the lock cylinder being pivotable into closed and open positions by at least one key associated therewith and insertable in the lock cylinder. The rotary cylinder lock is constructed such that a second key can be inserted into the lock cylinder with the second key having, at a location other than in cases of the main key, notches or projections or the like controlling additional locking members. The second key actuates, by pivoting, a switching unit which, if necessary, triggers a safety device so as to prevent unauthorized use of the motor vehicle. | ||||||

| 80 | LOCK WITH CYLINDER INCORPORATING LATERALLY BIASED BAR ENGAGING CORRESPONDING KEY | EP02801241.7 | 2002-10-18 | EP1436478A1 | 2004-07-14 | NUGENT, Walter, Joseph |
| A lock and key set in which the lock includes a cylinder rotatable in a barrel which barrel is rotatable to actuate the latch wherein the cylinder incorporates a laterally spring biased bar which includes slots or projections adapted to engage with corresponding slots or projections on the keys so that the bar can be aligned in one of three positions in which its ends are within the diameter of the cylinder or one of each end of the bar projects beyond the cylinder to engage with the barrel. This is applicable to pin tumbler locks and locks of the type in which a latch means is actued by movement of actuating members through associated slots in latch elements there being two sets of latch elements such that when the slots in each set of elements are aligned, the actuating members can pass through. One set of latch elements are positioned by a setting key and the other set are positioned by a corresponding access key. | ||||||
