  • Patent number: 10781613
    Abstract: A lock assembly includes a cylinder portion having an open end which receives a key. The assembly further includes a stem portion operatively connected to the cylinder portion and torsion spring operatively attached to the first and second lock portions, wherein the stem portion is capable of biased rotational movement independent of the cylinder portion. The lock assembly also includes at least one locking ball received atop the stem portion, the at least one locking ball being extendable and retractable from at least one slot in a housing of the lock assembly. A compression spring received about the stem portion biases the at least one locking ball towards a distal end of the stem. During installation into a lock receptacle, the locking ball is urged radially against the stem, causing the stem to rotate against the bias of the torsion spring, as well as urged axially rearward within the slot against the bias of the compression spring.

  • Patent number: 7610784
    Abstract: A lock assembly includes a lock body and a keyway covering member. The lock body includes a keyway disposed on an outer surface. The keyway covering member is assembled with the outer surface of the lock body, and is slideable between a covering orientation and an uncovering orientation. When the keyway covering member is in the covering orientation, a covering portion of the keyway covering member aligns with the keyway to cover the keyway. When the keyway covering member is in the uncovering orientation, an opening in the keyway covering member aligns with the keyway to permit insertion of a key in the keyway.

  • Patent number: 7448236
    Abstract: An adjustable coupler lock for locking a trailer hitch such that a trailer cannot be removed from a vehicle. The coupler lock comprises a lock body with a locking mechanism and a locking plate, and also comprises a shaft having a narrow and a flange end, and also having multiple recesses along the length of the shaft for engagement with the locking plate of the lock body. The recesses along the length of the shaft have a vertical edge which engages the locking plate such that the lock body cannot be removed from the shaft without unlocking the locking mechanism. The recesses also have a tapered edge that allows for slidable movement of the lock body along the shaft, without unlocking the locking mechanism, for the purpose of adjusting the lock to the size of the latch.

  • Patent number: 7377134
    Abstract: A locking mechanism for securing the cover of a thin-walled box to the box frame. The locking mechanism includes a clip bracket adapted to engage a wall of the box frame, a lock body adapted to latch to the clip bracket and engage the box cover, a locking member carried by the clip bracket and adapted to clamp the clip bracket to the box wall when the locking member is in a clamping position, and a pivotable actuating lever adapted to actuate the locking member into the clamping position. The locking member and the actuating lever can be implemented as a two-piece system comprising first and second pivoting members. Alternatively, the locking member and the actuating lever can be integrally formed as a one-piece system. The locking mechanism is capable of multiple mounting positions on the box without drilling, and uses a spring-loaded plunger assembly that allows for a quick, keyless, slam installation.

  • 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.
