  • Patent number: 11732435
    Abstract: A latching system associated with a dipper door of a dipper includes a latch bar that engages with a body of the dipper. The latch bar defines a longitudinal axis. The latch bar includes a housing, one or more shims, and a wear member removably coupled to the housing. The wear member defines a wear surface and a wear axis extending parallel to the wear surface. An angle defined between the wear axis and the longitudinal axis is less than 45 degrees. The latching system also includes an arm member pivotally coupled to the dipper door such that the arm member is pivotable along a first pivot plane. The arm member contacts a portion of the latch bar for moving the latch bar along the longitudinal axis. The latching system includes a guide assembly having a guide pulley and an actuation member that causes pivoting of the arm member.

  • Patent number: 8961062
    Abstract: An inertial lockout mechanism is coupled to a latch mechanism, such that, during a collision event, the inertial lockout mechanism will move to an interference position such that the latch mechanism will be retained in a locked position as an inertial force is realized on the latch mechanism. Specifically tailored compression spring configurations ensure that the inertial lockout mechanism will move to the interference position before the latch mechanism can move to the unlocked position.

  • Patent number: 8313126
    Abstract: A trash container locking apparatus includes a housing which is secured to a surface of a trash container. The housing includes a pivot member rotatably mounted in an outer wall of the housing for rotation about a pivot axis and having an inner portion inside the housing and an outer portion outside the housing. A latch member is secured to the pivot member inside the housing. A swing arm secured to the pivot member outside the housing and associated with a locking bar which extends over a lid of the trash container. A latch paddle is pivotally mounted in the housing to hang vertically in a latch engaging position when the housing is mounted on the trash container. The latch member and latch paddle have interengaging formations which engage in a locking position to prevent the latch member and associated swing arm from rotating.

  • Patent number: 7520542
    Abstract: A childproof gate latch for an enclosure such as a fence is provided with a latching member attached to a gate. The latching member is received through a lock opening in a fence support as the gate is closed.

  • Patent number: 7481468
    Abstract: A blocking apparatus is cooperable with the latch lever of a vehicle door latching mechanism to prevent the latch lever from moving during a crash event, which prevents the latching mechanism from allowing the vehicle door to open. The blocking apparatus includes a housing supporting a linearly movable plunger engagable with a cam surface on the latch lever and a blocking member pivotally mounted for movement between a normal position and a blocking position. The blocking member moves into the blocking position due to the imposition of crash forces on the blocking member during a crash event. A centering spring mechanism biases the blocking member into the normal position and can return the blocking member into the normal position to permit movement of the latch lever after the crash event has occurred. The plunger is biased into engagement with the latch lever so as to move with the cam surface.

  • Patent number: 7360330
    Abstract: A multi-purpose, front-loading display frame includes a front frame member having a pair of opposite first and second lateral side sections, a rear frame member having a pair of opposite first and second lateral side sections, at least one hinge for pivotally joining the first lateral side section of the front member to the first side section of the rear frame member to permit pivotal movement between an open position, in which the second side sections of the front and rear frame members may be pivoted apart from one another, and a closed position, in which the second side sections are disposed closely adjacent to one another. A lock is mounted on one of the second side sections of one of the front and rear frame members, and at least one latch plate is engageable with the lock. The latch plate is mounted on the other of the second side sections of the other of the front and rear frame members for cooperative engagement with the lock.

  • Patent number: 6829917
    Abstract: A weapon container and lock assembly for mounting in a vehicle, for example, an aircraft, that may be subject to a positive accelerated gravity environment. The weapon container has a container body defining an interior cavity therein and a top lid that is selectively moved between an open position and a closed position with respect to the container body by a container opening assembly. A lock assembly is provided for movement between a first, locked, position and a second, unlocked, position upon application of an accelerated gravity condition of a predetermined level. In use, the lock assembly prevents movement of the container opening assembly when the lock assembly is in the first position and allows movement of the container opening assembly when the lock assembly is in the second position.

  • Patent number: 5597188
    Abstract: A latching device which detects the initial shocks of major earthquakes and activates safety devices before the onset of destructive ground motions. A unidirectional vertical threshold seismoscope is integrated with mechanical and electromechanical safety devices to latch cabinets closed, secure movable objects, shut off gas, water, and electric utilities, activate alarms, early warning networks, and related automated response systems. The device is fully self contained, requires no external power, and is virtually impervious to nonearthquake noise in that it is designed to respond specifically to the vertical acceleration and displacement characteristic of the initial shock waves of a major earthquake.
