Abstract
A safety anchor system provides protection to workers that are working on an elevated platform. The safety harness system preferably includes two anchoring devices that are spaced apart on a concrete slab. An extension member extends between the anchor devices. Each individual has a tether that extends between a safety harness worn by the individual and the extension member. The tether is moveable along the entire length of the extension member, which results in a greatly increased range of available motion to the worker. The anchor devices preferably have latching members with extensions of varying dimensions to accommodate a variety of concrete slab configurations.
Claims17
A safety anchor system for protecting an individual from falling from an elevated platform, comprising:
- a first anchor device having a first member and a second member that is moveable along a longitudinal axis relative to the first member to selectively adjust a width of the first anchor device, the first and second members each having an outward end with a latching member supported on the outward end, the latching member being adapted to latch onto an edge of a concrete panel upon adjustment of the width of the first anchor device, the latching members each including a central portion having a first projection on one side of the axis at a first distance from the axis, and a second projection on an opposite side of the axis at a second distance from the axis extending from the central portion toward a center of the first anchor device, the second distance being greater than the first distance;
- a second anchor device having a first member and a second member that is moveable along a longitudinal axis relative to the first member to selectively adjust a width of the second anchor device, the first and second members each having an outward end with a latching member supported on the outward end, the latching member being adapted to latch onto an edge of a concrete panel upon adjustment of the width of the second anchor device the latching members each including a central portion having a first projection on one side of the axis at a first distance from the axis, and a second projection on an opposite side of the axis at a second distance from the axis extending from the central portion toward a center of the second anchor device, the second distance being a greater than the first distance;
- an extension member having a length extending between the first and second anchor devices, the extension member being secured to each of the anchor devices;
- at least one tether having a first end secured to the extension member that is moveable along the length of the extension member;
- and
- a harness secured to a second end of the tether, the harness being adapted to be worn by an individual.

A safety anchor system for protecting an individual from falling from an elevated platform that includes at least one concrete panel having sides with grooves, comprising:
- a first anchor device having a first tube and a second tube that are selectively moveable relative to each other to selectively adjust a width of said first anchor device, said first and second tubes each having an outside end with a latching member secured to said outside end, each latching member including a plate portion that is positioned nonparallel with a longitudinal axis of a corresponding one of said tubes and a first extension on one side of said longitudinal axis and extending from said plate portion in a direction toward a center of said anchor device and spaced a first distance from said longitudinal axis and a second extension on an opposite side of said longitudinal axis and extending from said plate portion in a direction toward said center of the corresponding anchor device and wherein said second extension is spaced from said longitudinal axis a second distance that is greater than the first distance, said extensions being adapted to be received in the groove on the concrete panel, and a locking portion to selectively lock said first and second tubes relative to each other to maintain a selected width of said anchor device with said extensions engaging the grooves on the concrete panel such that said first anchor device is maintained in a first position on the concrete panel;
- a second anchor device having a first tube and a second tube that are selectively moveable relative to each other to selectively adjust a width of said second anchor device, said first and second tubes each having an outside end with a latching member secured to said outside end, each latching member including a plate portion that is positioned nonparallel with a longitudinal axis of a corresponding one of said tubes and a first extension on one side of said longitudinal axis and extending from said plate portion in a direction toward a center of said second anchor device and spaced a first distance from said longitudinal axis and a second extension on an opposite side of said longitudinal axis and extending from said plate portion in a direction toward said center of the corresponding anchor device and wherein said second extension is spaced from said longitudinal axis a second distance that is greater than the first distance, said extensions being adapted to be received in the groove on the concrete panel, and a locking portion to selectively lock said first and second tubes relative to each other to maintain a selected width of said second anchor device with said extensions engaging the grooves on the concrete panel such that said second anchor device is maintained in a second position that is spaced from the first position;
- and
- an extension member extending between and secured to said first and second anchor devices.

A safety anchor system, comprising:
- a harness to be worn by an individual;
- a tether having a first end secured to the harness;
- and
- an anchor device secured to a second end of the tether, the anchor device including a first tube and a second tube that are selectively moveable along a longitudinal axis relative to each other to adjust a length of the anchor device, the first and second tubes each having a latching member at an outward end for securing the anchor device to a work platform, each latching member including a central plate portion and having a first projection on one side of the axis at a first distance from the axis, and a second projection on an opposite side of the axis at a second distance from the axis extending from the plate portion toward the center of the anchor device, the second distance being greater than the first distance such that the latching members accommodate different sized work platforms.
