发明名称 Steel knot for ropes
摘要 The steel knot for ropes is a device to replace the time-honored metal hook and conventional knots used on tow and hoist ropes, and also tethering ropes. The device comprises two appropriately spaced rounded metal rings held together in proper relation to each other by 2 or more metal bars or similar connectors. To use the device, a rope is inserted through the rings and is then wrapped around the intended load. The end of the rope is then tucked between the device and a pushed-out portion of the rope. Next, either an overhand knot is tied in the end of the rope, or the rope end is wrapped around the device once again, and again tucked in between the pushed-out portion and the steel device. Tension on the rope secures the device in place. When pressure is relaxed the rope is easily untied. Should the rope break under stress, it will pull out of the steel piece immediately, thus permitting the steel device to drop free of the rope. Metal will not be thrown in the opposite direction by the elasticity of the rope as would occur if part of the hook remains attached to the rope. When it is desired to use a rope without a steel knot, the steel device is slid off the rope.
