KNOT TYING TOOL

摘要

Tools and methods are disclosed for tying a knot. A knot tying tool can include an elongated housing and an insert member. The housing can have first and second body portions having different outer cross-sections. A first chamber can extend within the housing with a slit that opens into the chamber. The insert member can also have a slit opening into a second chamber. The insert member can have an inner cylinder rotatable and movable within the first chamber. Rotation of the inner cylinder within the first chamber can move the knot tying tool between a locked and an unlocked position, the first and second slits being aligned in the unlocked position to allow a line to pass through the first and second slits into the second chamber.

1. A knot tying tool for forming a knot with a line, the knot tying tool comprising:
an elongated housing with a proximal end and a distal end, the housing comprising:
a first body portion having a first outer cross-section;a second body portion adjacent the first body portion and having a second outer cross-section different from the first outer cross-section thereby forming a shoulder between the first body portion and the second body portion;a first chamber defining and extending along a longitudinal axis, the first chamber being cylindrical and having a proximal opening in the first body portion and a distal opening in the second body portion located distally from the proximal opening along the longitudinal axis;a first slit running longitudinally along the housing from the proximal opening to the distal opening; anda holder extending from the distal opening of the first chamber, the holder having a cut-out at an end of the holder configured for securing a hook or line to the elongated housing; and an insert member comprising:
an inner cylinder rotatable and movable within the first chamber;a stop member at a proximal end of the inner cylinder configured to limit translation of the inner cylinder within the first chamber along the longitudinal axis;a second chamber extending through the insert member and configured to receive a line therein, the second chamber having a proximal chamber opening and a distal chamber opening located distally from the proximal chamber opening along the longitudinal axis;a hole to provide access through the inner cylinder to the second chamber, wherein the hole is positioned distal of the elongated housing's distal opening the when the inner cylinder is positioned within the first chamber of the elongated housing with the stop member engaged with the proximal end of the elongated housing; anda second slit running longitudinally along the insert member from the proximal chamber opening to the distal chamber opening, wherein rotation of the inner cylinder within the first chamber moves the knot tying tool between a locked and an unlocked position, the first and second slits being aligned in the unlocked position to allow a line to pass through the first and second slits into the second chamber.
