Abstract
An apparatus for deploying a line includes a disc having a generally V-shaped circumferential channel for retaining the line prior to deployment. The V-shaped channel guides a first wound turn of the line toward the central plane of the disc, and provides an enlarged space into which the turns of the line are unwound during deployment. The enlarged space prevents tangling of the line when the turns are unwound from the disc during deployment.
Claims19
An apparatus for deploying a line, comprising:
- a disc having a top side, a bottom side, and an edge extending circumferentially around the disc, a generally V-shaped circumferential channel being defined between the top side and the bottom side and being open at the edge of the disc, the circumferential channel having opposing sidewalls that converge continuously one toward the other along a radial inward direction, from the edge of the disc toward the center of the disc, the circumferential channel being substantially symmetric about a central plane that is defined midway between the top side and the bottom side of the disc, and the sidewalls of the circumferential channel intersecting at said plane,
- wherein the circumferential channel accommodates a predetermined length of the line when a plurality of turns of the line is wound onto the disc, and
- wherein the opposing sidewalls of the circumferential channel cooperate to guide a first turn of the line that is wound onto the disc toward the central plane.
An apparatus for deploying a line, comprising:
- a throwable disc having a top side, a bottom side, and an edge extending circumferentially around the disc, a generally V-shaped circumferential channel being defined between the top side and the bottom side of the disc and being open at the edge of the disc, the circumferential channel having opposing sidewalls that converge continuously one toward the other along a radial inward direction, from the edge of the disc toward the center of the disc, the circumferential channel being substantially symmetric about a central plane that is defined midway between the top side and the bottom side of the disc, and the sidewalls of the circumferential channel intersecting at said plane;
- and
- a line having one end attached to the disc and having a free end opposite the attached end, the free end for being grasped by a user throwing the throwable disc, wherein the circumferential channel houses a predetermined length of the line when a plurality of turns of the line is in a wound condition, and
- wherein the opposing sidewalls of the circumferential channel cooperate to guide a first turn of the line that is wound onto the disc toward the central plane.

An apparatus for deploying a line, comprising:
- a throwable disc fabricated from a material that is buoyant in water, the disc having a top side, a bottom side, and an edge extending circumferentially around the disc, a generally V-shaped circumferential channel being defined between the top side and the bottom side of the disc and being open at the edge of the disc, the circumferential channel having opposing sidewalls that converge continuously one toward the other along a radial inward direction, from the edge of the disc toward the center of the disc, the circumferential channel being substantially symmetric about a central plane that is defined midway between the top side and the bottom side of the disc, and the sidewalls of the circumferential channel intersecting at said plane;
- and
- a line that is buoyant in water and having one end attached to the disc and having a free end opposite the attached end, the free end for being grasped by a user throwing the throwable disc,
- wherein the circumferential channel houses a predetermined length of the line when a plurality of turns of the line is in a wound condition, and
- wherein the opposing sidewalls of the circumferential channel cooperate to guide a first turn of the line that is wound onto the disc toward the central plane.
