Door cable tensioning device

A door cable tensioning device for retaining tension on a door cable of a trailer, said device comprising:

• a cargo trailer having a rear end, said rear end being open into an interior of said cargo trailer;
• a door being hingedly coupled to said cargo trailer, said door being positionable between an open position and a closed position, said door having a lower edge and an upper edge and a top surface extending between said lower edge and said upper edge, said cargo trailer having a floor, said lower edge being hingedly coupled to an intersection between said floor and said rear end of said trailer, said top surface being oriented at a downwardly angle with said rear end of said trailer when said door is in said open position wherein said top surface is configured to extend between said rear end and a support surface, said top surface resting against said rear end when said door is in said closed position;
• a pulley being coupled to said cargo trailer, said cargo trailer having a ceiling, said pulley being positioned adjacent to said ceiling, said pulley being biased to rotate in a first direction, said pulley being rotatable in a second direction;
• a cable being coupled between said pulley and said door, said pulley urging said door into said closed position when said pulley is biased to rotate in said first direction, said pulley being biased to rotate in said first direction with a spring force being less than a weight of said door wherein said pulley is configured to assist a user with lifting said door upwardly from the support surface to position said door in said closed position, said pulley rotating in said second direction when said door is urged into said open position;
• a coupler comprising a base portion and a pin portion extending upwardly from said base portion, said base portion having a bottom surface, said bottom surface being coupled to said top surface of said door, said coupler being located closer to said upper edge of said door than said lower edge of said door, said cable having a distal end with respect to said pulley, said distal end being coupled to said pin portion of said coupler;
• a bracket being coupled to said door, said bracket having a first section being oriented at an angle with a second section, said first section having a topmost surface and a bottommost surface and a distal edge with respect to said second section, said second section having a lateral surface, said lateral surface lying on a plane being oriented perpendicular to said topmost surface, said bottommost surface of said first section lying on said top surface of said door, said first section being positioned adjacent to said base portion of said coupler, said bracket being located between said coupler and said lower edge of said door, said first section having a pair of holes each extending through said topmost surface and said bottommost surface, each hole of said pair of holes being positioned closer to said distal edge of said first section than said lateral surface of said second section, said pair of holes being spaced apart from each other and being distributed along said distal edge;
• a pair of fasteners, each fastener of said pair of fasteners extending through a respective hole in said first section of said bracket, each fastener of said pair of fasteners engaging said door for retaining said bracket on said door;
• a bolt being coupled to said bracket, said bolt extending laterally away from said bracket, said bolt being coupled to said second section of said bracket, said bolt being oriented perpendicular to said lateral surface of said second section, said bolt being centrally located on said second section, said bolt having a distal end with respect to said lateral surface of said second section, said bolt having threads extending from said distal end of said bolt toward said lateral surface of said second section, said bolt having a length being greater than a length of said first section of said bracket, said distal end of said bolt being spaced outwardly said distal edge of said first section;
• a tensioning spring being disposed on said bolt, said tensioning spring having a coiled portion and an arm portion, said coiled portion being wrapped around said bolt, said arm portion being oriented perpendicular to said bolt, said arm portion pressing against said cable, said coiled portion biasing said arm portion to urge said cable toward said door to retain tension on said cable, said arm portion inhibiting said cable from unwrapping from said pulley when said door is urged into said closed position wherein said tensioning spring is configured to inhibit the user from having to replace said cable onto said pulley, said arm portion having a distal end of said arm portion with respect to said coiled portion, said arm portion having a first bend being positioned closer to said distal end of said arm portion than said coiled portion, said first bend defining a primary section of said arm portion being perpendicular to a secondary section of said arm portion, said primary section intersecting said coiled portion, said arm portion having a second bend being located between said first bend and said distal end of said arm portion, said second bend defining a tertiary section of said arm portion, said tertiary section being aligned with said secondary section, said tertiary section defining a cable space between said tertiary section and said secondary section, said tertiary section angling toward said secondary section, said distal end of said arm portion being associated with said tertiary section, said cable extending through said cable space, said tertiary section retaining said cable in said cable space, said arm portion being directed toward said rear end of said cargo trailer when said door is in said open position;
• a washer being positioned on said bolt, said washer abutting said coiled portion of said tensioning spring, said washer being spaced from said distal end of said bolt;
• and
• a nut being threaded onto said threads of said bolt, said nut compressing said washer against said coiled portion of said tensioning spring.
