  • Flexible barrier holding and manipulating mechanism
    Patent number: 4553739
    Abstract: A flexible barrier element for a passageway defined by two spaced posts is held in a raised taut position to block the passageway by placement of a hand lever having a lost motion connection with the barrier element in a level position of engagement with a bracket fixed on one post. Swinging of the hand lever to a depressed position relative to the bracket on which it is pivotally mounted slackens the flexible barrier element and lowers it to a ground level position allowing unobstructed passage between the posts defining the passageway. A second bracket on the second post has a flexible barrier element attached to it.
