Patent number: 10434343Abstract: A quick-release attachment point for fall protection. It includes a body portion, a retaining member, a capturing and releasing mechanism, a remote control module, and an energy source. The body portion, and the retaining member in a normal position thereof, together form a closed aperture for capturing a D-ring attachment point or other article of attachment hardware. The capturing and release mechanism is operated through the remote control module to free the retaining member so that it can move, in response to energy provided by the energy source, in a direction away from the normal operating position and in an amount such that it no longer closes the aperture, so that the article can escape from the apparatus.Type: GrantFiled: March 14, 2011Date of Patent: October 8, 2019Assignee: Climb Tech, LLCInventors: Karl Guthrie, Joseph Schwartz

Patent number: 8646575Abstract: A beam anchor. The beam anchor includes an elongate cross-member, a lanyard attachment structure attached to the cross-member, a pair of first and second spaced apart beam capturing members attached to the cross-member. Either or both capturing members may have a locking mechanism that is cantilevered from the capturing member, and the lanyard attachment structure may have a lanyard attachment ring connector that is capable of rotating about the cross-member but that is constrained to a fixed position along the cross-member by use of a ring or partial ring structure attached to the cross-member that extends through a slot in the lanyard attachment ring connector.Type: GrantFiled: February 15, 2012Date of Patent: February 11, 2014Assignee: Climb Tech, LLCInventors: Karl Guthrie, Ivan A.

Patent number: 8424638Abstract: A swivel anchor point for fall protection. The swivel anchor point includes a ring element and a housing element. The ring element defines a closed attachment aperture. The housing element is adapted to receive and retain the ring element such that the ring element can be freely rotated through a swivel angle of at least 180 degrees about a swivel axis, and freely rotated through a pivot angle of at least 90 degrees about a pivot axis that is perpendicular to the swivel axis and that substantially intersects the swivel axis. The ring element includes two spaced apart leg members, the leg members having foot portions extending inwardly, toward the swivel axis. The foot portions have respective, spaced apart relatively enlarged ends.Type: GrantFiled: April 1, 2010Date of Patent: April 23, 2013Inventors: Karl Guthrie, Joseph Schwartz

Patent number: 8353653Abstract: An anchor bolt providing for fall protection. The anchor bolt has an anchoring device that may be of any standard type, for making use of an aperture either in or through a structure as an anchoring point, an elongate flexible member connected to the anchoring device at one end of the elongate flexible member, and a handle connected to a second end of the flexible member. The handle member is pivotally attached to the second end, for pivoting about the elongate axis of the flexible member as it extends from the second end. Preferably, the anchoring device is a novel, toggling type in which a toggling member is pivotally attached to the flexible member at a ball joint.Type: GrantFiled: October 9, 2009Date of Patent: January 15, 2013Inventors: Karl Guthrie, Joseph Schwartz

Patent number: 8312966Abstract: A beam anchor. The beam anchor is generally used for attaching to a flanged beam that has been made a part of a structure, to provide fall protection for a worker working on the structure. The beam anchor includes a main cross-member with a beam capturing member at each end. One or both of the capturing members have associated therewith respective yaw restoring mechanisms providing a combined restoring torque for urging the cross-member in counteraction to twisting thereof by a yaw angle in a yaw plane that is substantially parallel to the surface portions. Preferably, a lanyard attachment member is slidably disposed on the cross-member and spring-biased into a relatively centered position between the capturing members.Type: GrantFiled: September 23, 2009Date of Patent: November 20, 2012Inventors: Karl Guthrie, Joseph Schwartz
