Quick release line attachment

Abstract

An attachment device attachable to a string, rope, cord or other flexible line that remains in a fixed position on the line without knotting the line or clamping the device to the line. The attachment device is quickly attached and removed without the need for additional tools to attach or release the device from the line. The device includes a secondary attachment to allow a second device to be permanently attached to the attachment device, allowing the second device to be quickly attached and released from a line.

1 . A device attachable to a line, the device comprising:
 a central member;   an aperture extending from a first side of the central member to a second side of the central member;   a slot between the first side and second side of the central member wherein a first portion of the slot extends into the aperture from a first outer surface of the central member and a second portion of the slot extends into the aperture from a second outer surface of the central member;   a first projection extending from a first sidewall of the slot towards a second sidewall of the slot and a second projection extending from the second sidewall of the slot towards the first sidewall of the slot, wherein a first distance from the first projections to an opposing sidewall, near the outer surface of the central member but excluding a tip of the first projection, is greater than a second distance from the first projection to the opposing sidewall near the aperture; and   barbs that at least partially restrict the slot near the first and second sides of the central member.   
   
   
       2 . The device as recited in  claim 1  further including a third portion of the slot that extends into the aperture from the first outer surface, wherein said second portion of the slot is positioned between the first and third portions of the slot. 
   
   
       3 . A device attachable to a line, the device comprising:
 a line receiving member having a central axis and an aperture sized larger than a diameter of said line, the aperture extending through the member along a portion of the central axis, wherein an aperture axis of at least a portion of the aperture is offset from the central axis of the member;   a slot wherein a first portion of the slot extends into the aperture from a first outer surface of the line receiving member and a second portion of the slot extends into the aperture from a second outer surface of the line receiving member; and   barbs near the first and second sides of the member.   
   
   
       4 . The device as recited in  claim 3  further including a third portion of the slot that extends into the aperture from the first outer surface, wherein said second portion of the slot is positioned between the first and third portions of the slot. 
   
   
       5 . A fishing sinker attachable to a fishing line, the sinker comprising:
 a main body including a channel to thread a fishing line there through wherein a first portion of the channel extends into the main body from a first outer surface and a second portion of the channel extends into the main body from a second outer;   a projection extending into at least a portion of the channel, a base of the projection being closer to an opposing sidewall of the channel than an upper portion of the projection, excluding a tip of the projection, wherein the fishing line threads around the projection; and   barbs that at least partially restrict the channel near opposite ends of the main body.   
   
   
       6 . The fishing sinker as recited in  claim 5  further including a third portion of the channel that extends into the main body from the first outer surface, wherein said second portion of the channel is positioned between the first and third portions of the channel.
