A system and method for a locking mechanism that includes an ability to indicate that a fall event has occurred as well as indicate proper engagement via a signal cable coupled through a harness. The locking mechanism includes a mechanical indicator that is disposed within the locking mechanism (as opposed to far away from the locking mechanism at a remote cable attachment point) that can visually indicate that a fall event has occurred. Further, the locking mechanism includes electronic components including three magnetic actuators and corresponding electronic switches that signal change of state. Locking tabs and a leading edge of the insert respectively include the three magnetic actuators. The electronic switches, which may be magnetically activated reed switches, signal status change to an external controller and, optionally, an external computer.

A buckle assembly includes a first buckle member having an insertion member, a second buckle member having a receiving slot, and a locking arrangement. The locking arrangement includes a locking slot indently formed on the insertion member, a locking member movably mounted in the second buckle member at a position corresponding to the locking slot, and a releasing key detachably attached on the second buckle member to drive the locking member to move between a locked position and a releasing position. In the locked position, the locking member is moved to engage with the locking slot to prevent the insertion member from detaching from the receiving slot. In the releasing position, the locking member is driven by the releasing key to retract from the locking slot so as to allow the insertion member to be pulled out of the receiving slot.

A control docking station system for controlling locking engagement between a first female member and a male member that together form a locking mechanism. The first female member is connected to a safety device. The male member can be locked to and released from the first female member. The system includes a controller configured to sense an unsafe interlock signal. A second female member is operably connected to the controller's housing. Each female member includes a receiver base and a pair of pivoting locking tabs that is engageable with a key-like projection on the male member. The male member may be unlocked from the first female member when the controller senses an interruption to the unsafe interlock signal or if the unsafe interlock signal is overridden. The male member may be docked in the second female member during safe circumstances and/or the safety device is unused.

A safety belt buckle includes a base and a latch. The base includes a chamber with at least one positioning member disposed therein, and an opening communicating with the chamber. The latch includes a tongue with at least one recess with one open side, is adapted to be inserted into the chamber through the opening. The at least one positioning member is introduced into the at least one recess through the open side thereof to be engaged with the at least one recess when the tongue is inserted into the chamber. By the design mentioned above, the latch could be engaged with the positioning member of the base through the recess. Whereby, the latch still could be engaged with the base securely and would not be released easily and accidentally when any one of the latch and the base is laterally pushed or pulled.

A system and method for a locking mechanism that includes an ability to indicate proper engagement via a signal cable coupled through a harness. The locking mechanism may include electronic components including three magnetic actuators and corresponding electronic switches that signal change of state. Locking tabs and a leading edge of the insert respectively include the three magnetic actuators. The electronic switches, which may be magnetically activated reed switches, signal status change to an external controller and, optionally, an external computer. Further, status signals and power signals may be routed through a steel cable or woven nylon harness that coupled the locking mechanism to a local anchor point. Change of status notification may be important on critical safety worksites where lack of mechanical and electronic connection can be life threatening.

A buckle assembly includes a female buckle body that interchangeably mates with either one of a male buckle body or a retainer ring defining a leading bar. The female buckle body has a receptacle to receive an extension portion of the male buckle body slidable therein. A biased lever body is pivotally supported on the female buckle body for cooperating with a catch on the male buckle body between a blocking position retaining the extension portion in the receptacle and a released position allowing removal of the extension portion. The female buckle body also has a slot aligned with the receptacle to receive the leading bar of the retainer ring therein so that the lever body can also selectively retain the retainer ring mated with the female buckle body.

A buckle assembly includes a first buckle component, a second buckle component and an operating component. The first buckle component includes a locked portion. The second buckle component includes a locking portion. The locking portion engages with the locked portion along a lateral direction of the buckle assembly when the second buckle component is mated with the first buckle component along a mating direction. The operating component is partially embedded in and partially exposed out of the second buckle component. The operating component is slidable relative to the second buckle component. The operating component drives the locking portion to move away from the locked portion for disengaging the locking portion from the locked portion during a sliding movement of the operating component relative to the second buckle component. The present invention has advantage of saving labor and easy operation.

A buckle for a child safety seat harness having a base part and a latch part, the latch part having a releasable latching mechanism that includes a plurality of magnetic elements arranged to urge the base and latch parts into engagement during a connection operation and to urge the base and latch parts apart during a disconnection operation that also releases the latch.

A buckle with a first pawl that is biased by a pair of magnets that are oriented in opposition to each other to provide a repelling force, and with a second pawl that is biased by another pair of magnets that are oriented in opposition to each other to provide a repelling force.

A buckle and a pet restraint device, wherein the buckle includes a male buckle portion and a female buckle portion, wherein the male buckle portion has a first through hole and a second through hole through which the webbing passes, the female buckle portion has a third through hole through which the webbing passes, and the inner walls of the first through hole and the second through hole are spaced with a plurality of anti-skid ribs; anti-skid stripes are arranged around the first through hole and the second through hole. The buckle can effectively prevent the webbing on the buckle from lateral deflection or slipping, so that the webbing can always fit on the pet's body, avoiding safety problems caused by the looseness of the webbing or scratching of the pet's skin caused by the overturning of the webbing due to the lateral deflection.
