Detangling lead assembly
First Claim
1. A detangling lead assembly comprising:
- a handle subassembly rotatably coupled to a proximal end of a body subassembly;
an elongated flexible lead having a first lead end and a second lead end;
the body subassembly comprising a pulley;
and the lead following a lead path from a distal end of the body subassembly, around the pulley and extending from the distal end of the body subassemblywhereby the first lead end and the second lead end extend generally in a distal direction from the handle subassembly and the lead is generally movable back and forth around the pulley;
and the lead path through the body subassembly causes an overlap of the lead in an overlap location distal to and off of a surface of the pulleywherein the body subassembly further comprising a housing;
wherein the housing has a distal end having a first and a second lead eyelet defining a first and a second exit point respectively for the lead from the housing;
the first and the second lead eyelets are separated by an eyelet offset distance between an inside edge of the first and the second lead eyelets and the eyelet offset distance is greater than an inside groove diameter of the pulley;
and the eyelet offset distance defines an eyelet moment arm greater than a pulley moment arm defined by the inside groove diameter of the pulley whereby an eyelet moment force from the lead on the housing is greater than a pulley moment force on the pulley.

Abstract
A detangling lead assembly comprising an elongated flexible lead having a first lead end and a second lead end, a body subassembly comprising a pulley, the lead retained in a lead path from a distal end of the body assembly, around the pulley and extending from the distal end of the body subassembly whereby the first lead end and the second lead end extend generally in a distal direction from the handle subassembly and the lead is generally movable back and forth around the pulley. In some embodiments, the lead assembly further comprises a handle subassembly rotatably coupled to a proximal end of the body subassembly. In some embodiments, the housing further comprises exit points for the lead ends defining a moment arm for a moment to force the body subassembly to rotate and uncross a crossing of the lead ends.

1. A detangling lead assembly comprising:
-
a handle subassembly rotatably coupled to a proximal end of a body subassembly; an elongated flexible lead having a first lead end and a second lead end; the body subassembly comprising a pulley; and the lead following a lead path from a distal end of the body subassembly, around the pulley and extending from the distal end of the body subassembly whereby the first lead end and the second lead end extend generally in a distal direction from the handle subassembly and the lead is generally movable back and forth around the pulley; and the lead path through the body subassembly causes an overlap of the lead in an overlap location distal to and off of a surface of the pulley wherein the body subassembly further comprising a housing; wherein the housing has a distal end having a first and a second lead eyelet defining a first and a second exit point respectively for the lead from the housing; the first and the second lead eyelets are separated by an eyelet offset distance between an inside edge of the first and the second lead eyelets and the eyelet offset distance is greater than an inside groove diameter of the pulley; and the eyelet offset distance defines an eyelet moment arm greater than a pulley moment arm defined by the inside groove diameter of the pulley whereby an eyelet moment force from the lead on the housing is greater than a pulley moment force on the pulley. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A lead assembly comprising:
- a body subassembly;
a single lead received in the body subassembly; the single lead having a first lead end and a second lead end; the first lead end extending from the body subassembly at a first lead end length and the second lead end extending from the body subassembly at a second lead end length; a means to adjust the first lead end length and the second lead end length; and a means to rotatably anchor the body subassembly whereby the body subassembly rotates in reaction to one or more moments to avoid the first lead end wrapping around the second lead end; the means to adjust the first lead end length and the second lead end length comprises a pulley wheel rotatable coupled to the body subassembly; a lead path extending through the body subassembly and around the pulley wheel whereby the lead path causes an overlap of the lead over itself in an overlap location distal to and off of a surface of the pulley wheel; the overlap of the lead over itself is configured to provide a frictional engagement of an outside surface of the lead against itself creating a resistance force opposite a pulling force on the lead wherein the body subassembly further comprises a first and a second lead eyelet defining a first and a second exit of the lead path from a distal end of the body subassembly; the first and the second lead eyelets are separated by an eyelet offset distance between an inside edge of the first and the second lead eyelets; and the eyelet offset distance is greater than an inside groove diameter of the pulley wheel. - View Dependent Claims (10, 11, 12, 13)

14. A rotatable lead assembly comprising:
-
a handle subassembly rotatably coupled to a proximal end of a body subassembly; an elongated flexible lead having a first lead end and a second lead end; the body subassembly comprising a pulley; the lead following a lead path from a distal end of the body subassembly, around the pulley and extending from the distal end of the body subassembly whereby the first lead end and the second lead end extend generally in a distal direction from the handle subassembly; the body subassembly having a distal end having a first and a second lead eyelet defining a first and a second exit point respectively for the lead from the body subassembly; the first and the second lead eyelets are separated by an eyelet offset distance between an inside edge of the first and the second lead eyelets and the eyelet offset distance is greater than an inside groove diameter of the pulley; the eyelet offset distance defines an eyelet moment arm about a longitudinal axis of the body subassembly; the inside groove diameter of the pulley defines a pulley moment arm about the longitudinal axis of the body subassembly; and the eyelet moment arm is greater than the pulley moment arm whereby an eyelet moment force from the lead on the body subassembly is greater than a pulley moment force on the pulley and the body subassembly is urged to rotate in relation to the handle subassembly wherein the lead path through the body subassembly causes an overlap of the lead in an overlap location distal to and off of a surface of the pulley. - View Dependent Claims (15, 16, 17)
