1. Apparatus for handling a flexible elongate member, the apparatus comprising:
- a feeder unit mounted for movement along a predetermined path, andat least one fixed retaining unit mounted adjacent said path, said retaining unit having a loop, defining an opening therein, and a latching means mechanically associated with said loop for closing said opening, said retaining unit having a first condition in which the elongate member may be received into or withdrawn from the retaining unit, and a second condition in which the elongate member is retained in said retaining unit, said second condition of said retaining unit being an equilibrium position of said retaining unitwherein said feeder unit includes means for engaging said retaining unit and altering the condition of said retaining unit from said second condition to said first condition and feeding the elongate member into the retaining unit while said retaining unit is in said first condition andwherein upon said feeder unit being disengaged from said retaining unit said retaining unit shifts from said first condition to said second condition due to the force of gravity;
said feeder unit disengagement resulting whilst said feeder unit moves along said predetermined path in one direction.

Abstract
A system for handling cables and the like comprising a guide track (7) beneath which is fixed a plurality of space-apart retaining units (10). A trolley (8) is slidably mounted on the guide track (7) and accommodates a cable (5) which may be fixed at each retaining unit by pulling the trolley (8) along the track (7). By pulling the trolley in the opposite direction, the cable (5) may be released from each retaining unit.

11. An apparatus for handling a flexible cable, said apparatus comprising:
-
an elongate track; at least one retaining unit associated with said track, each of said retaining units comprising; a loop defining an opening therein, said loop being configured to receive and retain said cable; a first latching member pivotedly mounted on said loop to rotate about a horizontal axis in a generally vertical plane;
said first latching member being positionable in two orientations;
a first orientation wherein said first latching member is removed from said opening whereby said cable is insertable into said loop through said opening and a second orientation wherein said first latching member closes said loop opening;
said second orientation being an equilibrium orientation;
wherein gravity urges said first latching member to return to said second orientation whenever said first latching member is displaced from said second orientation;a second latching member pivotedly mounted on said loop, said second latching member having a channel therein configured to receive a portion of said first latching member and thereby retain said first latching member in said second orientation, a feeder unit adapted to move along said track, said feeder unit comprising; a frame having at least one wheel rotatably mounted thereon for associating with said track permitting said feeder unit to roll along said track; a cable mounting associated with said frame, a proximal end of said mounting adapted to position said cable without said opening;
a distal end of said mounting adapted to position said cable within said opening;an actuator shaft mounted on said frame, having an end adapted to contact initially said second latching member and rotate said second latching member so as to disengage said channel of said second latching member from said first latching member;
said actuator end also being adapted to subsequently engage said first latching member and rotate said first latching member about its axis thereby displacing said first latching member from its second orientation and retaining said first latching member in its first orientation while said cable mounting inserts said cable into said loop;wherein a disengagement of said feeder unit and said retaining unit results in said first latching member returning to its second orientation solely due to the force of gravity acting on said first latching member and said second latching member subsequently returning, solely under the force of gravity, to an orientation wherein said first latching member is received within said channel of said second latching member.
