Clutch having abutment surfaces

A clutch for lifting a concrete component having an edge-lift eye anchor embedded therein, the clutch comprising:

• a toroidal connector that defines:
• an inner circular passage from a front to a rear of the toroidal connector, a lower gap, and an upper opening from a left side to a right side of the toroidal connector;
• a latch that extends through the inner circular passage and is movable relative to the toroidal connector from:
• a disengaged condition in which the latch is retracted into the inner circular passage so that the lower gap is open to receive a head of the edge-lift eye anchor,
• to an engaged condition in which the latch spans the lower gap from the front to the rear of the toroidal connector to pass through an eye of the head and secure the edge-lift eye anchor to the toroidal connector;
• and
• a coupler that includes:
• a lower part that forms a lower loop extending through the upper opening of the toroidal connector, and
• an upper part, pivotal relative to the lower part, that forms an upper loop configured to couple the toroidal connector to a lifting apparatus,
• wherein the toroidal connector includes:
• a left sidewall;
• a right sidewall;
• a left flat bearing surface having a length that spans the lower gap and a width that extends from a left outer edge at the left sidewall to a left inner edge that is below the left outer edge;
• a right flat bearing surface having a length that spans the lower gap and a width that extends from a right outer edge at the right sidewall and a right inner edge that is below the right outer edge;
• a circular seat having a length that spans the lower gap and a width between the left inner edge and the right inner edge;
• a front inner surface;
• and
• a rear inner surface,
• wherein:
• the circular seat is arched over the lower gap from the left inner edge to the right inner edge,
• the left flat bearing surface is angled outwardly in a leftward direction away from a center of the width of the circular seat and is conformed to abut a rightward facing flat surface of a left castellation of the head of the edge-lift eye anchor;
• the right flat bearing surface is angled outwardly in a rightward direction away from the center of the width of the circular seat and is conformed to abut a leftward facing flat surface of a right castellation of the head of the edge-lift eye anchor,
• the circular seat, the left flat bearing surface, the right flat bearing surface, the front inner surface, and the rear inner surface define the lower gap, and
• the left flat bearing surface and the right flat bearing surface are angled outwardly to enable rotation of the toroidal connector about a longitudinal axis of the eye of the head when the edge-lift eye anchor is secured to the toroidal connector.
