  • Patent number: 8991224
    Abstract: A security apparatus for a ratchet type gunlock that has a ratchet for locking the gunlock. The security apparatus prevents the gunlock from being shimmed using shimming techniques well known in the art. A star-shaped cogwheel having asymmetrical teeth prevents the shim from reaching the locked ratchet. The security apparatus also provides an extended ratchet latching assembly that features a pivot and a unique shoe-shaped latch that attaches to a plunger via a ball head such that the connections provided between the three elements of the latching assembly enable the latching assembly to remain locked despite severe impact, wrenching or shaking, yet can be easily opened even once the forces being applied to the gunlock ceases even when the deformation to the gunlock is irreversible.

  • Patent number: 8756960
    Abstract: An improved cable lock device incorporating a lock housing incorporating both a cylindrical combination lock and axial friction fingers and associated with a flexible shackle that stores entirely inside handlebars of vehicles that utilize handlebars. The shackle is secured at one end to the lock housing and the other end to a toothed key to be inserted into the anterior end of the combination lock to form a locked loop for securing the vehicle. In the stored configuration of the device in the handlebar the toothed key is retained at the posterior of the lock housing. At its midpoint the shackle is bent substantially 180 degrees and attached to a small ball that will fit inside the handlebars. Resilient rings of fingers are attached on the axis of the lock housing. Upon lock insertion the resilient fingers deform to interior bore of the handlebar for friction locking.

  • Publication number: 20110048084
    Abstract: A lock and key mechanism reduces exposure to lock picking by including an extension into a key slot to receive and conceal tapered end portions of key pins. The only portions of key pins exposed in a key slot are cylindrical portions that are difficult to move from a resting position. A key includes a beveled leading edge and a spring-loaded pin activation element at the leading edge of the key. As the key is inserted into the key slot, the spring-loaded pin activation element is compressed to permit entry into the key slot. As the pin activation element reaches a pin, an aperture in the extension allows the spring-loaded pin activation element to move toward the key pin and move the key pin from its resting position. In this activated position, the tapered end portion of the key pin is exposed for further activation by the beveled leading edge of the key. The process is repeated until the pin activation element engages and activates each successive key pin and allows full insertion of the key.

  • Patent number: 7412858
    Abstract: There are provided a cam plate (5) that rotates in an unlocking direction and a locking direction, and a locking shaft (8) that moves between a locking position where rotation of a steering shaft is prevented and an unlocking position where the rotation of the steering shaft is permitted by rotation of the cam plate (5). The cam plate (5) is provided with a steering lock preventing unit (20) through a spring (22). The steering lock preventing unit (20) holds the locking shaft (8) in the unlocking position. A ball (23) moves on a moving surface (24) of a motor unit (4) opposed to the cam plate (5) by rotation of the cam plate (5). A projecting wall (25) is provided on the moving surface (24) at a position before the unlocking position in a range where the ball (23) moves from the locking position to the unlocking position.

  • Patent number: 7377137
    Abstract: A barrel lock for locking various utilities devices such as valves, meters, or enclosures associated with the control or distribution of gas, water or electricity includes a shank with a single driven ball that can be forced radially outward from the shank to lock onto a cap-like retainer such that the utilities device is restrained between the retainer and an enlarged head of the shank. Preferably, only a single driven ball is used to concentrate the clamping force at a single point, thereby creating an exceptionally high clamping pressure. For even greater clamping force, an accurately and strategically positioned end stop allows a drive ball to push against the driven ball at an extremely shallow angle of attack while preventing the two balls from accidentally toggling over center and irreversibly locking up. The barrel lock has infinite variable adjustment in an axial direction to fit a wide variety of devices.

  • Patent number: 7275402
    Abstract: A lock, such as a mortise lock, for a door. The lock comprises a locking cylinder that can be inserted into a door leaf and a shaft having two sections, each section of the shaft having a handle at the end, preferably a rotary knob or a standard door handle and being actively interconnected by a coupling after recognition of an authorisation code. The lock can be used for various applications as a result of its construction design, with a standard locking cylinder in various doors and that it allows, a simple, reliable, low-energy actuation of the locking mechanism. To achieve this, the coupling (11) comprises at least two, preferably four or more rolling members (17) that are guided in recesses (18) of a second part (10) of a first section (5) of the shaft (3).

  • Patent number: 7213424
    Abstract: The present disclosure relates to preventing rotation of a barrel lock when opened by a key. At least one example embodiment includes a rotationally actuated barrel lock for securing electric meter boxes and the like, and a spring loaded clip for mounting inside the meter box. Lock actuation is characterized by rotation of a key relative to the lock. The barrel lock includes a head portion, and a smaller diameter shank portion with flatted areas thereon. The clip includes, in at least one example, a lock receiving opening with internal protrusions which engage the flatted areas on the lock shank, thereby preventing rotation of the lock when it is engaged by the key.

  • Patent number: 6782725
    Abstract: A push button lock. The push button lock has a main housing with an aperture formed therethrough, a plunger which is axially moveable in the aperture of the main housing, and a ball retainer positioned in the aperture of the main housing. The ball retainer has a central aperture formed therein through which the plunger extends and a protrusion. Balls are placed on the ball retainer. An actuator is located in the main housing aperture above the ball retainer and is rotatable to an open position, wherein the actuator is in position to be pushed down to prevent the balls from moving away from the plunger shaft and thereby prevent the plunger shaft from moving relative to the ball retainer, and a locked position, wherein the balls are not retained against the plunger shaft and the plunger shaft can move relative to the balls retainer. A lock button having a lock housing and a lock cylinder is provided, with the lock cylinder being adapted to turn the actuator from the opened position to the locked position.

  • Publication number: 20040163430
    Abstract: A bottle security device includes an inner member, an outer member and a cap member that cooperate to lock the bottle security device on the neck of a bottle. The inner member includes a plurality of fingers that are adapted to fit under the bead on a bottle neck. The cap member and the outer member are connected to form an enclosure therebetween which houses a locking mechanism. The outer sleeve member of the device slides over the inner member and forces the fingers against the bottle neck. Pins are connected to the inner member and extend into the locking mechanism to lock the inner and outer members together when the inner member is inserted in the outer member. A magnetic key is used to separate the two pieces and release the security device from the bottle. The key attracts a portion of the locking mechanism to disengage the mechanism from the pin.
