The subject matter of the solution is an automatic snap buckle intended in particular for joining together sections of safety harness tapes wherein the snap buckle consists of a body and a plug, wherein in the body there is a connection eyelet for sewing of the end of a textile strap of the safety harness, wherein in the plug there is a second connection eyelet for the sewing of the other tape end and wherein the finger of the plug is pushed to a stop, which is a central post located at the end of the slot in the body

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 housing enclosing a locking bar for securing a latch. The latch is inserted into a latch cavity of the buckle assembly, pushing the spring-loaded locking bar into the housing until a convex feature of the latch passes a convex feature of the latch cavity, and slides to the side, whereupon the locking bar is extended by a compression spring, thereby locking the latch from release from the buckle assembly. The latch is released from the latch cavity by pulling a release cord or cable or trigger attached to the locking bar to overcome the spring tension and draw the locking bar up, thus allowing the latch to move away from the convex feature of the latch cavity and release from the buckle assembly.

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.
