Abstract
Systems and methods are provided for a tensioning device configured for increasing tension in a line. A system may include a rotating member configured to support a line, the rotating member being configured to rotate around a shaft. A locking member is configured to limit movement of the line when the line is supported by the rotating member. A tensioning handle is configured to have a closed position and an open position, where the tensioning handle is disengaged from the shaft when in a closed position, and where the tensioning handle is configured to be engaged with the shaft when the tensioning handle is in an open position.
Claims20
A tensioning device configured for increasing tension in a line, comprising:
- a rotating member configured to support the line, the rotating member being configured to rotate around a shaft;
- a locking member configured to limit movement of the line when the line is supported by the rotating member;
- a tensioning handle configured to have a closed position and an open position, wherein the tensioning handle is disengaged from the shaft when in a closed position, wherein the tensioning handle is configured to be engaged with the shaft when the tensioning handle is in an open position;
- and
- a locking pin that is configured to be extended into a receptacle of the shaft when the tensioning handle is engaged with the shaft.
A tensioning line system, comprising:
- a line configured for connection to a first rigid structure;
- a tensioning device, comprising:
- a rotating member configured to rotate around a shaft;
- a locking member configured to limit movement of the line;
- a tensioning handle configured to have a closed position and an open position, wherein the tensioning handle is disengaged from the shaft when in a closed position, and wherein the tensioning handle is configured to be engaged with the shaft when the tensioning handle is in an open position;
- and
- a locking pin that is configured to be extended into a receptacle of the shaft when the tensioning handle is engaged with the shaft;
- wherein the tensioning device is configured to be directly or indirectly connected to a second rigid structure.
A method of increasing tension in a line, comprising:
- accepting the line at an entry point of a tensioning device such that the line is guided around a rotating member and exits the tensioning device at an exit point, wherein initial tensioning of the line is provided via hand pulling of the line through the exit point;
- engaging a locking member against the line, wherein the locking member is configured to limit movement of the line such that the line can only be rotated around the rotating member in one direction;
- engaging a tensioning handle with a shaft of the rotating member when the tensioning handle is transitioned from a closed position to an open position, wherein the tensioning handle is configured to be retained in the closed position by a magnet or physical stop;
- and
- providing additional tensioning of the line when the handle is rotated via corresponding rotation of the shaft and the rotating member.
