Rotary Or Swinging Tumblers Patents (Class 70/301)
  • Patent number: 9316025
    Abstract: An actuating motor set includes a mounting base; a motor; a transmission set including a worm gear formed with a tooth, wherein two opposite ends of the worm gear respectively defining are a pushing end and a restoring end; and a spring including an engagement part and an abutment part. The engagement part is engaged with the tooth, and an inner diameter of the abutment part is larger than an outer diameter of the tooth. The spring is pushed spirally by the tooth upon rotation of worm gear, and thus moving back and forth on an axial direction of the worm gear. The spring idles when it is moved to the pushing end due to lack of engagement therewith, and the spring also idles when it is moved the restoring end due to lack of engagement therewith.

  • Patent number: 8555686
    Abstract: A lock includes a housing, a keypad disposed on the housing, and a latch assembled with the housing. The keypad includes a plurality of button assemblies, each including an axially depressible button member including a camming surface, a lock wheel having a plurality of camming teeth, and a latch releasing feature secured to the lock wheel for rotation therewith. Pressing the button member causes the camming surface to engage one of the plurality of calming teeth, thereby incrementally rotating the lock wheel between a plurality of rotational positions. When the button members of a predetermined one or more of the plurality of button assemblies are depressed a predetermined number of times, the latch releasing features of each of the plurality of button assemblies align with a plurality of blocking features of the latch to permit lateral sliding movement of the latch from a locked condition to an unlocked condition.

  • Publication number: 20130247626
    Abstract: A fence control feature described herein may be used with a combination lock. The fence control feature includes a trigger plate having an overcenter arm, a stop arm, and a cam follower arm disposed around a common pivot point. A bracket is preferably vertically elevated above the overcenter arm. An apron is preferably formed on the overcenter arm. The apron may be for preventing a nose of a pivotable fence lever arm from catching on the trigger plate. The apron may be a half-moon-shaped apron.

  • Patent number: 8359890
    Abstract: A light fence represented by aligned apertures in a plurality of wheels permits the passage of a light beam to a sensor to activate an electro-mechanical control for a lock. Such an arrangement avoids the sound-producing mechanical action of the typical tumbler lock and safeguards discovery of the opening combination. Rather than the typical case of a numerical sequencing combination, a novel approach is taken by using visual pattern recognition to align the apertures. The electro-mechanical control of the present invention additionally features optimized energy use, customizable settings, precision positioning, and an expansion of possible combination permutations by including direction of rotation.

  • Patent number: 7383708
    Abstract: A lock cylinder assembly has a base, multiple selecting disks and multiple disk sets. The base has an axis. The selecting disks are rotatably connected to the base along the axis of the base. The disk sets are operationally mounted along the axis of the base and are respectively connected to the selecting disks. Each disk set has multiple disks operationally mounted along the axis of the base. Accordingly, a lock cylinder assembly that can increase the difficulty of unlocking the lock cylinder assembly to improve the safety of using the lock cylinder assembly is provided.

  • Patent number: 6615626
    Abstract: A lock device having a rotatable identification brand includes a lock body defining a receiving space and formed with at least one view window, a rotatable member rotatably mounted in the receiving space of the lock body and provided with identification information that may be seen through the view window of the lock body, and a drive mechanism mounted on the rotatable member for rotating the rotatable member. The rotatable member may be driven and rotated by the drive mechanism, so that the user may watch the information printed on the rotatable member through the view window, thereby facilitating other people identifying the owner of the lock device, and thereby enhancing the aesthetic quality of the lock device.

  • Patent number: 6401505
    Abstract: A combination locker lock is provided having a three digit combination that can be set by a key to one of six different combinations. The locker lock includes a bolt that can retract into the case of the lock, fully extended from the case to function as a dead bolt, and partially extended from the case to function as a spring loaded automatic bolt. A plunger associated with the bolt is used to release the bolt from the partially to the fully extended position, and a single trigger associated with the bolt is used to hold the bolt in the partially extended position and the fully extended position.

  • Patent number: 6131428
    Abstract: A combination of the inventive combination lock can be easily and conveniently changed by the user. A clutch selectively disengages the drive tumbler from the lock spindle. With the drive tumbler disengaged and the tumblers in an aligned position, the user rotates the lock knob by a desired increment, thereby changing all of the numbers by the increment. In one embodiment, the clutch is operated by a cup mounted around the drive cam and engaging the drive tumbler, a spring biasing the drive tumbler against the cup and the drive cam, and the cup carrying a button that, when pressed, moves the drive tumbler out of engagement with the drive cam. In another embodiment, the clutch is operated by a thumb screw projecting through a rear panel of the combination lock that moves an upper part of the drive cam out of engagement with a lower part of the drive cam, allowing relative rotation of the lock dial and the drive tumbler.

  • Patent number: 4756176
    Abstract: A fence lever control device for a combination lock provides a pivoted plate having an arm positioning a spring to normally bias the fence lever of the lock in a position out of engagement with the fence lever operating cam wheel, with an actuator roller mounted to the cam wheel which engages a follower surface on the pivoted plate once on each complete revolution of the cam wheel in a given direction in response to similar rotation of the dial shaft to which the cam wheel is mounted to thereby shift the pivoted plate and its associated spring mounting arm in an over center fashion to place the spring in a position to bias the fence lever toward the cam wheel, movement of the fence lever into engagement with the cam wheel being prevented by engagement between the fence member and the tumbler wheel assemblies when the wheel assemblies are not oriented in a predetermined relationship.
