Abstract
A fencing apparatus for preventing animals from climbing over a fence, which includes a plurality of first and corresponding second elongated members, is provided. Each of the first and second elongated members pivot relative to each other from a first stationary position to a second variable position. A flexible plastic netting is connected to and extends across the plurality of first and second elongated members. When connected to a vertically extending fence, the fencing apparatus extends from the vertically extending fence such that the second elongated member pivots downwardly upon being subject to a load e.g., by the weight of a climbing animal.
Claims17
A fencing apparatus for being secured proximate the top of a fence, the fencing apparatus comprising:
- a plurality of spaced-apart first elongated members that each include a first end having a mounting bracket for being secured to the fence, and a second end opposite the first end, a stop extending outwardly from the second end of each first elongated member;
- a corresponding plurality of second elongated members that each include a primary end and a secondary end opposite the primary end, the secondary end of each second elongated member being pivotably attached to the second end of a corresponding first elongated member by a pivot pin;
- a torsion spring for each corresponding pair of first and second elongated members, each torsion spring including a central coil surrounding the pivot pin, and first and second wire ends extending from the central coil, the first wire end engaging a first hole in the second end of the first elongated member and the second wire end engaging a second hole in the secondary end of the second elongated member of each pair of pivotally attached first and second elongated members to bias the first and the second elongated members to a first stationary position;
- and
- a flexible netting connected to and extending across the plurality of first and second elongated members,
- wherein when in the first stationary position, each torsion spring biases the respective second elongated member to contact at least a portion of the stop of the respective first elongated member such that the first and the second elongated members extend at a first angle between 5 to 175 degrees with respect to each other, and wherein each second elongated member is pivotably movable downwardly from the first stationary position to a second variable position with respect to the corresponding first elongated member.

A fencing system comprising:
- a vertically extending fence for enclosing a perimeter, the vertically extending fence having an upper end;
- and
- a fencing apparatus connected to the vertically extending fence, the fencing apparatus comprising:
- a plurality of spaced-apart first elongated members that each include a first end having a mounting bracket secured to the vertically extending fence proximate the upper end, a second end opposite the first end, and a stop extending outwardly from the second end;
- a corresponding plurality of second elongated members that each include a primary end and a secondary end opposite the primary end, the secondary end of each second elongated member being pivotably attached to the second end of a corresponding first elongated member by a pivot pin;
- a torsion spring for each corresponding pair of first and second elongated members, each torsion spring including a central coil surrounding the pivot pin, and first and second wire ends extending from the central coil, the first wire end engaging a first hole in the second end of the first elongated member and the second wire end engaging a second hole in the secondary end of the second elongated member of each pair of pivotally attached first and second elongated members to bias the first and the second elongated members to a first stationary position;
- and
- a flexible netting connected to and extending across the plurality of first elongated members, second elongated members, and a portion of the vertically extending fence,
- wherein when in the first stationary position, each torsion spring biases the respective second elongated member to contact at least a portion of the stop of the respective first elongated member such that the first and the second elongated members extend at a first angle between 5 to 175 degrees with respect to each other, and wherein each second elongated member is pivotably movable downwardly from the first stationary position to a second variable position with respect to the corresponding first elongated member.
