  • Patent number: 10232199
    Abstract: A safety harness connector assembly including a D-ring, a device connector system and a shaft. The D-ring is generally a C-shape including a first end portion, a second end portion and mid-portion. The mid-portion extends between the first end portion and the second end portion. The first end portion has a first D-ring aperture and the second end portion having has a second D-ring aperture that is aligned with the first D-ring aperture. The device connector system includes at least one device connection aperture that is configured and arranged to couple a device to the safety harness connector assembly. The device connector system has at least one shaft connection aperture. A shaft is received in the first and second D-ring apertures of the D-ring and in the at least one shaft connection aperture of the device connector system to pivotally couple the device connector system to the D-ring.

  • Patent number: 10086234
    Abstract: A fall prevention assembly to prevent injuries when a user climbing a pole and falls, is provided. The fall prevention assembly includes a pole strap, a first connector, a floating back plate, a second connector and a lanyard. The pole strap has a first end, a second end and a mid portion between the first end and the second end. The first connector has a first end that is slidably coupled proximate the first end of the pole strap. The floating back plate is engaged between a portion of the first connector and the pole strap and is configured and arranged to selectively bind the pole strap to the first connector. The second connector is coupled a select distance from the second end of the pole strap. The lanyard has a first end, a second end and mid portion between the first and second ends. A second end of the first connector is slidably coupled to the lanyard.

  • Patent number: 10016638
    Abstract: An energy absorber assembly for use with a safety harness comprises a connector, a bracket assembly, a fastener, and an energy absorber. The connector is configured and arranged to operatively connect to the safety harness. The fastener operatively connects the bracket assembly and the connector, and the fastener releases the bracket assembly from the connector when subjected to a predetermined load. The energy absorber operatively connects the bracket assembly and the connector, and the energy absorber includes a first portion and a second portion that separate to absorb shock after the bracket assembly is released from the connector.

  • Patent number: 9273717
    Abstract: A connector that includes a carabiner and an insert is provided. The base of the insert has a length that extends between a first end and a second end and a width that extends between a first side edge and a second side edge. A barrel connector of the insert centrally extends from the first side edge of the base. The barrel connector receives a barrel of a gate of the carabiner. A first ear extends from the second side edge of the base proximate the first end of the base. The first ear includes a first carabiner retaining channel that selectively engages a first portion of the carabiner. A second ear extends from the second side edge of the base proximate the second end of the base. The second ear includes a second carabiner retaining channel that selectively engages a second portion of the carabiner.
