The use of a constant-force spring avoids abrupt snap-back of the extended cord when released, as well as the need for excessive pulling force on the cord as it approaches full extension, which tends to cause the stanchion to tip over. Dynamic balance between the contractive force of the stretchable cord and the retractive force of the constant-force spring achieves a taut but not unyielding tension in the interconnecting cords between stanchions. | 09-11-2014 |
