Quickly tensioned divider line for swimming pools

A swimming pool having the pool surface divided into lanes by a plurality of divider lines, comprising, in combination, a swimming pool having at least two opposite sides between which the divider lines extend;

• a plurality of means along each side for fixedly attaching the divider lines to fixed locations along said sides;
• and a plurality of quickly tensioned divider lines attached to said means along each side;
• the divider lines comprising, in combination, a first divider line section adapted for attachment to a first fixed location in a swimming pool;
• and a tensioning toggle attached to the line section and adapted for attachment to a second fixed location in a swimming pool, the line thereby being located in a divider line position in the pool;
• the toggle having a bifurcated inner first and second bifurcated outer toggle arms, the first toggle arm being pivotably mounted on the second toggle arm, and movable between retracted and extended positions, in the retracted position being axially coextensive over at least a part of its length with respect to the second toggle arm, and in the extended position being axially extended over at least a part of its length with respect to the second toggle arm;
• said first toggle arm having a pivot pin linking two portions of said first bifurcated toggle arm, and having first attaching means linked to the pivot pin for pivoting movement therewith with respect to the first toggle arm and nested between the bifurcated inner first toggle arm in the retracted position thereof;
• and second attaching means on the second toggle arm;
• the first toggle arm in the retracted position putting a divider line attached to one of the attaching means under relative tension, and in the extended position putting a divider line attached to one of the attaching means under relative slack;
• and means movable between positions retaining the first toggle arm in the retracted position and releasing the toggle arm from the retracted position to permit it to enter the extended position.
