| 141 | LOCK | US13129080 | 2009-11-12 | US20110226026A1 | 2011-09-22 | Grant Macdonald |
| A lock (10) comprises a housing (11) defining a mounting face (12), a locking mechanism (21) accommodated in the housing (11) and operable to change between a locking state and a release state and a set of operating elements (25) with buttons (26) accessible at the front of the housing and actuable, such as by axial displacement, to operate the locking mechanism (21). The locking mechanism (21) can be changed from the locking state to the release state in response to actuation of, and only of, a selected group of the operating elements (25). These elements can additionally be manipulated, in particular rotated, to select the group. The buttons of the selected group can be identified by respectively associated digits forming a code. The lock further comprises a slidable blocking plate (31) blocking the rotation of the operating elements (25) and cancelling means (36-38) operable to cancel the blocking by the plate (31). The cancelling means includes a key barrel (37) accessible for operation externally of the housing (11) at a place, in particular the front of the housing, separate from the mounting face. Operation of the key barrel (37) thus has the consequence of freeing the buttons (26) for rotation to change the code. | ||||||

| A code lock is revealed. The code lock includes a housing, a return base, a plurality of locking seats, a fixed seat, a moveable seat, a code seat, a plurality of code members and a housing base arranged sequentially from top to bottom. A press button corresponding to each locking seat is disposed on the housing and each locking seat has at least one tooth that locks with a hook of the return base when the press button is pressed to push the locking seat. A stopping block is arranged at the bottom of each locking seat while the code member is set with a code post correspondingly. Moreover, the moveable seat includes a code area and a non-code area for mounting the code member and the code seat has a plurality of C-shaped holes corresponding to the code members. Thereby a simple-structured and easy-operated code lock is formed. | ||||||
| 143 | LOCKABLE ENCLOSURE | US12886855 | 2010-09-21 | US20110067461A1 | 2011-03-24 | Dean D. Hacker |
| A locking arrangement includes a latch assembly, a locking mechanism, and a user operable opening member. The locking mechanism holds the latch assembly in a latching position when the locking mechanism is in a locked condition and allows the latch assembly to move to an unlatching position when the locking mechanism is in an unlocked condition. The opening member is movable from a normal position to an opening position. When the locking mechanism is in the unlocked condition, movement of the opening member to the opening position moves the latch assembly from the latching position to the unlatching position. The opening member is operatively connected to the latch assembly by a compressible member, such that when the locking mechanism is in the locked condition, movement of the opening member to the opening position compresses the compressible member without moving the latch assembly out of the latching position. | ||||||

| 146 | SUITCASE LOCK ASSEMBLY | US11833795 | 2007-08-03 | US20080236211A1 | 2008-10-02 | Min-Tsung Ma |
| A suitcase lock assembly formed of a push-button lock and a pin tumbler lock for working with two locking units and two linking units in a suitcase, in which each push button of the push-button lock has two grooves for receiving a movable member to force a movable plate away from the linking units for allowing the linking units to be driven by the push blocks to open the locking covers, and the pin tumbler lock has an actuation block rotatable with the key to move the movable plate away from the linking units for allowing the linking units to be driven by the push blocks to open the locking covers. Thus, the user can selectively use the push-button lock or the pin tumbler lock, enhancing the security and convenience of use of the suitcase. | ||||||
| 147 | Pushbutton lock | US11603040 | 2006-11-22 | US20080115546A1 | 2008-05-22 | Jeffery Hu |
| A pushbutton lock coupling with a handle lock includes an outer handle assembly, an outer lock case, a first control assembly, a second control assembly, a bolt assembly, a cam assembly, an inner lock case and an inner handle assembly. The first control assembly and the second control assembly form a chain movement through the cam assembly. After unlocking the door can be directly opened through an outer handle. The pushbutton lock further has lock blades with alterable arrangement to reset the number. Moreover, a clear pushbutton is provided to clear and correct mistaken depression of the pushbuttons. Thus use and operation of the pushbutton lock are more convenient. | ||||||
| 148 | Combination lock having a knob rotatably mounted therein to activate/deactivate the locking mechanism of the combination lock | US11388960 | 2005-12-28 | US20070144226A1 | 2007-06-28 | Tony Miao |
| A combination lock has a plurality buttons movably received in the casing and a knob rotatably received in the casing. When specific buttons are pressed downward, rotating the knob from a first position to a second position, the balls in the downward movement buttons are limited in the limiting holes in the buttons by the abutting faces of a frame. Rotating the knob to a third position allows pins of the pressed buttons to be secured and limited in the longitudinal paths. Pressing the returning rod is able to release the arms which are received in the arm stays in the pressed arms. Rotating only the core relative to the combination of the rotator and the body is able to drive the second abutting block to move so as to return all the pins back to their original positions to be ready for next use. | ||||||

| Pushbutton lock where size reduction can be achieved by reducing the external dimension, including a planetary gear mechanism 18 where a drive gear serves as a sun gear 31 that is concentrically arranged within a casing 2 with an outside-house knob (operating member) 5, and a planetary gear 32a is arranged so that the range of revolution thereof with respect to the sun gear 31 overlaps the range of movement of a slider 17. Thereby, the slider 17 is moved in the unlock direction in response to the turning operation of the knob 5. | ||||||
| 150 | Latching devices for gates and doors | US10504006 | 2003-02-07 | US20050199025A1 | 2005-09-15 | James West |
| A latching device (1) particularly for installation such as swimming pool gates may have an automatic magnetic latch with a child resistant device to control access. The child resistant device may include an operating handle (10) at an elevated location to be out of the reach of the child and an alternative operating device (11) is provided at a lower location with child resistance provided typically by a push button arrangement (12) acting through a cam and cam follower to raise a latching arm (3) against the biasing to the latching position. A simple pronged key (16) for a pushing action can be provided, but another aspect consists in a mechanically actuatable key pad (20) which can readily be operated by an adult even in a wheelchair, but which is resistant to child actuation. For example, a selected two of eight buttons may be required to be depressed to permit the key to actuate the push button. | ||||||
| 151 | Tamper resistant combination lock | US34762 | 1998-03-04 | US06119493A | 2000-09-19 | Robert L. Carter; George W. Carter, Jr. |
| An improved tamper resistant combination lock with large planar easy to shift blocking slides with spring fingers that fool the lock picker into believing all three positions of the slides are blocking positions, rather than passing positions. The slides block or pass spaced spheroidal obstructions on a plunger. A small bifurcated clip prevents the complete removal of the plunger when all blocking slides are in the pass position. In one embodiment the lock is a padlock-type with a "U" shaped shackle that lies in a common plane with the slides to reduce lock size. | ||||||
| 152 | Key box device | US844537 | 1997-04-18 | US5768921A | 1998-06-23 | Matthew S. Hill |
| A lid is secured to the base of a key box device that defines an enclosed compartment for securing a spare key. The lid carries push-buttons and a knob for locking the lid to the base. The surface of the lid is generally flush with the plane of the base edges thereby eliminating locations for prying the lid from the base. A flanged portion in the lid and corresponding recessed portion in the base sidewalls provide gripping sidewalls to facilitate handling of the lid. | ||||||
| 153 | Lever-actuated combination locking apparatus | US473536 | 1990-02-01 | US5197313A | 1993-03-30 | Roy L. Chandler; Richard P. McCullough |
| A locking apparatus that includes first and second structural elements that are adapted to be juxtaposed and positioned next to one another in a "locked" mode, and physically separated from one another when "unlocked." When in its locked mode, the locking apparatus is restrained against separation until a manual force is simultaneously applied to appropriate levers, ends of which are accessible on the exterior of the apparatus.A plurality of levers are mounted on the first of the two structural elements for rocking movement about a pivotal axis carried by the first element. Each lever has a first end that protrudes externally of the apparatus, and a second end that is sized and shaped so that it may be engaged with a lip surrounding an associated aperture in the second structural element. A biasing device is provided for continuously biasing each of the levers to a centered rest position, where at least one of the levers will be in an overlapping or interfering position with respect to the adjacent lip of its associated aperture. In a preferred embodiment, there are two configurations for the locking levers; one is normally engaged and the other disengaged when they are in their centered rest positions. Knowing the correct combination to open the locking apparatus involves knowing which levers must be moved and which direction they must be moved. Removing finger pressure from the exposed ends of the levers allows the levers to automatically return to their centered positions. | ||||||
| 154 | Quick opening, child-safe container with digital combination lock | US833004 | 1992-02-10 | US5189894A | 1993-03-02 | William M. Buck |
| A lock box is provided with a locking cover held locked by a locking element. The lock mechanism is operated by the fingers of a hand actuating individual tumblers, one for each finger, simultaneously. The fingers push against the tumblers and the distance they push them is determined by the length of the fingers which are held by interdigital stops. The tumblers are spring biased against the finger motion. Each tumbler is provided with a stop and pass mechanism that is adjustable along the length of the tumbler to correspond to a particular finger length so that the pass elements of each tumbler will all be aligned to permit passage of the locking element when a particular hand actuates the mechanism, whereas hands of other elements will position at least one of the stop elements so that the locking element cannot pass and the container remains closed. | ||||||

| 157 | Push-button padlocks having swivel-only shackles | US382214 | 1989-07-20 | US4952228A | 1990-08-28 | Jewell A. Taylor; Robert J. Bretl |
| A push-button padlock having a swivel-only shackle, the free end of which is receivingly engaged by a sleeve that is reciprocable into the padlock body housing upon actuation of a thumb latch member projecting through the housing, preferably through a hole in the front face. The shackle is an inverted J-shaped shackle with the longer end entrained in the padlock body where it engages a latching mechanism which includes the thumb latch and shackle sleeve members. The thumb latch is preferably of breakaway construction and the sleeve may be rotatable. A locking mechanism of any desired type to selectively lock and unlock the latching mechanism may be employed. One preferred locking mechanism is of push-button type, and another preferred locking mechanism is a key lock mechanism, both of which are operative to selectively lock and unlock the latching mechanism that may be employed. | ||||||

| A clutch system for use in the door locking arrangement has a drive member. A latch acutating member and a permutation lock reset member are disposed on either side of the drive member. The drive member is operatively connected to the actuating means, for example a door knob or a lever handle, so that the drive member drives the latch actuating member, to retract the latch member of the door locking arrangement, when a correct combination has been inserted into the permutation lock of the door locking arrangement. When an incorrect combination has been inserted, the drive member drives the permutation lock reset member to reset the permutation lock. A linkage operatively connects both the latch operating member and the permutation lock reset member to the control shaft of the permutation lock. The linkage serves to operatively connect the control shaft to the actuating means either through the drive member and the latch actuating member when the correct combination has been inserted, or through the drive member and permutation lock resetting member when an incorrect combination has been inserted. The linkage is symmetrically disposed so that only minor modifications are required to adapt the arrangement from an actuating means which rotates in a counter-clockwise direction to an actuating means which rotates in a clockwise direction. | ||||||

| A push-button padlock having a swivel-only shackle, the free end of which is receivingly engaged by a sleeve that is reciprocable into the padlock body housing upon actuation of a thumb latch member projecting through the housing, preferably through a hole in the front face. The shackle is an inverted J-shaped shackle with the longer end entrained in the padlock body where it engages a latching mechanism which includes the thumb latch and shackle sleeve members. The thumb latch is preferably of breakaway construction and the sleeve may be rotatable. A locking mechanism of any desired type to selectively lock and unlock the latching mechanism may be employed. The preferred locking mechanism is of push-button type, comprising a button block member having a plurality of holes in a spaced array for receiving and retaining two types of buttons, one or more Type A Combination Button(s) and the balance being Dead Pin B Buttons. A transverse bore in the button block intersects the push-button holes to receive a resilient member that engages arcuate grooves in the side of the push-buttons in a first up position and a second, depressed position. The buttons are configured adjacent their lower ends to engage slots in the locking plate, which slots are interspersed with enlarged arcuate relieved portions (holes) aligned with holes in the faces of the lock and the button block. The buttons are configured with adjacent blocking and passing diameter portions that either prevent or permit the locking plate to reciprocate when the correct combination buttons are pressed. | ||||||
