Abstract
A secure safety anchor that is easy to utilize is provided for attachment to structural angle irons in marine installations and the like. The anchor includes a vise grips with movable and stationary jaws, and a head welded to the stationary jaw. A flange surface portion of the head extends substantially perpendicular to an imaginary line between the vise grips jaws when in the clamping position, and a number of force concentrating set screws pass through the flange surface at an angle of about 15 degrees with respect to the imaginary line. A through-extending opening in the head provides for attachment of a safety belt clasp.
Claims20
A structure for anchoring onto an angle iron or the like, comprising:
- vise grips, including a stationary jaw, movable jaw, and jaw movement lever means;
- an imaginary straight line extending between said stationary and movable jaws substantially parallel thereto when said jaws are in a clamping position;
- a head fixed to said stationary jaw;
- said head including a flange surface portion thereof extending in a dimension substantially perpendicular to, and intersecting, said imaginary line;
- and said surface portion being spaced from all portions of said stationary jaw a substantial distance along said imaginary line, so that when a first portion of an angle iron is received between said stationary and movable jaws, a second portion of angle iron, generally perpendicular to the first portion, is operatively engaged by said surface portion;
- and
- means defining a through-extending opening in said head, extending in a dimension generally perpendicular to both said flange surface and said imaginary line, and formed in a portion of said head remote from said flange surface and adjacent said vise grip stationary jaw.
A safety anchor comprising:
- vise grips including a stationary jaw and a movable jaw, and an imaginary straight line extending between said jaws substantially parallel thereto when the jaws are in a clamping position;
- a head fixed to said stationary jaw;
- said head including a portion thereof comprising reaction force applying means for applying a force vector in a direction substantially perpendicular to said imaginary line;
- and
- safety belt receiving means associated with said head and vise grips for facilitating attachment of a safety belt thereto.
In combination an anchoring structure and an angle iron;
- said angle iron comprising a first portion and a second portion generally perpendicular to said first portion;
- said anchoring structure comprising:
- vise grips, including a stationary jaw, movable jaw, and jaw movement lever means;
- an imaginary straight line extending between said stationary movable jaws substantially parallel thereto when said jaws are in a clamping position;
- a head fixed to said stationary jaw;
- said head including a flange surface portion thereof extending in a dimension substantially perpendicular to, and intersecting, said imaginary line, and spaced from said stationary jaw along said imaginary line;
- and safety belt receiving means associated with said head and said vise grip for facilitating attachment of a safety belt thereto.
