20080307838 | COMBINED KEY AND COMBINATION RESETTABLE LOCK - A combined key and combination resettable lock is disclosed. The combination lock has a set of shaft and a set of parallel number wheels, and the set of shaft is axially movable and enclosed by the parallel number wheels. The key lock has a lock body and an outer sleeve, and the outer sleeve is selectively rotatable in accordance with the lock body. The outer sleeve further includes a protrusion and comes into contact with one end of the set of shaft. The outer sleeve is rotatable to a reset position, and the protrusion is against and presses the end of the set of shaft when the outer sleeve rotates to the reset position. | 12-18-2008 |
20090107193 | COMPOUND LOCK - A compound lock has a common housing, a latch assembly, a supplementary lock and a combination lock. The latch assembly is rotatably attached to and protrudes from the common housing. The combination lock and supplementary lock are mounted in the common housing and engage the latch assembly, and either may rotate the latch assembly. Thus, in general, people may unlock the compound lock using either the combination lock or the supplementary lock with a key when the combination is forgotten without breaking the compound lock. | 04-30-2009 |
20090301147 | Compound lock - A compound lock comprises: a shell, a combination locking mechanism, and a key locking mechanism. The shell has a panel providing a plurality of blocking walls protruding from the interior surface thereof. The combination locking mechanism is assembled in the shell, and has a plurality of locking disks. The locking disks each rotates on a sleeve and are penetrated by a shaft. The sleeves each is covered by a spring, one end of the sleeve forms a flange. The pushing piece provides a plurality of abutting portions. Both ends of the spring abut on the flange and the abutting portion respectively. Via this arrangement, when the locking disks are not turned to the correct positions, the blocking wall will block the flange of the sleeve. Users need to use the correct combination of numbers to lock the compound lock or change the correct combination of numbers. | 12-10-2009 |
20100257907 | Lock Structure with Auto-Reset Function - A lock structure including an activation device, a combination lock, and a setting device is provided. The combination lock has a plurality of dials, a shaft passing through the dials, and a plurality of first gears disposed on one side of each dial. Each first gear further includes a missing tooth. One end of the shaft is connected to the activation device. The setting device has a plurality of second gears corresponding to the first gears and a setting shaft, wherein one end of the setting shaft passes through the second gears and the other end is connected to the activation device. When the activation device is activated, the second gears are driven to rotate the first gears, so that when each second gear runs free with the missing tooth of each first gear, the dials are in a predetermined position. That is, by means of the activation device and the setting device, the dials of the combination lock can automatically return to the predetermined position after opening or closing the lock. | 10-14-2010 |
20100319419 | MASTER KEYED COMBINATION LOCK - A multiple dial lock includes reset dials rotatable around a lock shaft. Each reset dial must be at a specific angular position for a user to unlock the lock or reset the combination. Each reset dial has a magnet. A master key includes sensors, each in communication with one signal. Each of the signals indicates to a user that a respective magnet is adjacent a respective sensor, thus assisting a user in recovering a lost combination. A rotary lock includes a dial which rotates a drive cam, which in turn rotates several wheels to their unlocking positions. One magnet for each wheel is provided on the drive cam. Each magnet communicates with one sensor provided on a master key, which also includes signals, indicating that a respective magnet is adjacent a respective sensor, thus assisting a user in recovering a lost combination. | 12-23-2010 |
20110083483 | DOUBLE-SYSTEM LOCK APPARATUS - A double system lock apparatus comprises a lock shell, a combination lock, a key lock, and a control piece set. The lock shell has a panel and a main base assembled with each other. The combination lock has a plurality of rotating discs, coupling springs, couplings, and a shaft. The key lock has a lock cylinder and a sleeve set. From back to front, the control piece set has a first control piece, a second control piece, and a third control piece. By means of the control piece set working between the combination lock and the key lock, a double system lock apparatus of simple structure but well function has been formed. | 04-14-2011 |

20110289988 | LOCK HAVING AN INDICATORY LOCK CORE - A lock includes a housing and a key-operated lock core mounted on the housing. The key-operated lock core has a spindle with a keyhole defined therein. The spindle is movable between an original position where the spindle is allowed to be rotated with respect to the housing to put the lock in a locked or unlocked state, and an indicative position where the spindle is also allowed to be rotated to put the lock in the locked or unlocked state. | 12-01-2011 |
20120067091 | ROTATING DISK LOCK MECHANISM - A rotating disk lock mechanism that includes a lock housing containing a plurality of rotatable disks. Each disk having a central aperture and being positioned in a stack such that the central apertures form a keyway. At least one of the disks includes a reduced central aperture with a diameter that is substantially less than a diameter of at least another one of the central apertures. The combination of the lock mechanism is determined in part by the number of disks with reduced central apertures and their placement in the stack. | 03-22-2012 |
20120186313 | DUAL LOCKING DEVICE - A dual locking device includes a first casing and a second casing. A receiving space is defined between the first casing and the second casing. The second casing has a through hole defined therein. An axial shaft passes through the through hole. A latch member is connected with the axial shaft. A locking mechanism and a key operated mechanism are received in the receiving space. The locking mechanism is connected with the axial shaft for driving the axial shaft. The key operated mechanism has a lock core disposed therein and having a key hole defined therein for being inserted and rotated by a key, such that the lock core drives the axial shaft. Accordingly, the locking mechanism and the key operated mechanism are separately operable to move the latch member between a locking position and an unlocking position. | 07-26-2012 |
20120291503 | Door Locking System With An Idle Handle - A door locking system with an idle handle has a door panel having a front face, a rear face, a hinged side, a free side, an upper side, a lower side, and an electronic lock and a mechanical lock installed in the door panel respectively having a keypad and a keyhole on the front face. The system further has a level toggler, at least one bolt, a chamber defined therein, a handle seat, a handle lever, a latch lever, a linking arm, a swivel pillar, a paddle shifter, an upright toggler, and an handle lever resume spring. | 11-22-2012 |
