Length adjusting devices and method of using the same

A length adjusting device comprising:

• a body having a first side and a second side extending in spaced relation to one another, the first and second sides defining first and second planes, respectively;
• a first cam operably assembled in relation to the body and having a first proximal cam end positioned between the first and second sides;
• a second cam operably assembled in relation to the body and having a second proximal cam end positioned between the first and second sides and adjacent to the first proximal cam end;
• an axle that rotatably attaches the second cam to the body;
• a channel formed by a space between the first proximal cam end and the second proximal cam end;
• wherein the second cam is configured to rotate with respect to the body from a first position to a second position to expand the size of the channel upon the application of a first force exerted on the second cam towards the second position;
• and
• wherein the second cam is rotatable about the axle with respect to the body from a third position to a fourth position to expand the size of the channel upon the application of a second force exerted on the distal end of the second cam towards the fourth position.

A system for using a length adjusting device adapted to be tethered to a user via an external device, and capable of surrounding and selectively moving along a lanyard, the system comprising:

• a length adjusting device comprising:
• a body having a first side and a second side extending in spaced relation to one another, the first and second sides defining first and second planes, respectively;
• a first cam operably assembled in relation to the body and having a first proximal cam end positioned between the first and second sides;
• a second cam operably assembled in relation to the body and having a second proximal cam end positioned between the first and second sides and adjacent to the first proximal cam end, the second cam further comprising a distal end comprising a cam body having opposing surfaces with an opening formed therethrough, wherein an elongated axis extends centrally through the opening in a direction of rotation of the second cam and substantially parallel to the first and second planes, wherein the external device passes through and out of the opening in a direction parallel the elongated axis and parallel to the first and second planes;
• an axle that rotatably attaches the second cam to the body;
• a channel formed by a space between the first proximal cam end and the second proximal cam end;
• a handle attached to the body and rotatable from a first position to a second position about a rotation point upon application of a first force;
• a lanyard, a portion of which is positioned through the channel;
• an external device passed through and out of the opening and comprising connecting hardware;
• wherein the body is configured to rotate with respect to the second cam from a third position to a fourth position to expand the size of the channel to form an expanded condition upon the application of the first force exerted on the handle towards the second position, whereby the lanyard is allowed to move through the channel in the expanded condition.

A method of using a length adjusting device adapted to be tethered to a user via an external device, and capable of surrounding and selectively moving along a lanyard comprising the steps of:

• providing a length adjusting device comprising:
• a body having a first side and a second side extending in spaced relation to one another, the first and second sides defining first and second planes, respectively;
• a first cam operably assembled in relation to the body and having a first proximal cam end positioned between the first and second sides;
• a second cam operably assembled in relation to the body and having a second proximal cam end positioned between the first and second sides and adjacent to the first proximal cam end, the second cam further comprising a distal end comprising a cam body having opposing surfaces with an opening formed therethrough;
• an axle that rotatably attaches the second cam to the body;
• a channel formed by a space between the first proximal cam end and the second proximal cam end;
• a handle attached to the body;
• providing a lanyard, and positioning a portion of the lanyard through the channel;
• providing an external device comprising connecting hardware, and passing the external device through and out of the opening;
• rotating the handle from a first position to a second position upon application of a first force, wherein the rotation of the handle from the first position to the second position rotates the body with respect to the second cam from a third position to a fourth position expanding the size of the channel to form an expanded condition, and allows the lanyard to move through the channel in the expanded condition;
• and
• rotating the second cam about the axle with respect to the body from a fifth position to a sixth position to expand the size of the channel by applying a second force on the distal end of the second cam towards the sixth position by the external device.
