Abstract
An attachment to a fence, such as a chain link fence, used to confine a dog, prevents the dog from climbing the fence or using the top of the fence to assist himself in escaping over the fence. The attachment creates a region of instability, superjacent the top of the fence, which will not support the dog's weight and thus does not allow the dog to cling to or push off of the top rail of the fence. The region of instability is created by a freely rotatable roller attachment or a flexible panel attachment, both of which yield under the weight of the canine.
Claims6
Apparatus for preventing an animal from transversing a fence at the top thereof comprising:
- (a) means for providing a region of instability proximal said top of said fence comprising a plurality of flexible members extending upwardly and outwardly from said fence with each one of said plurality of flexible members in lateral abutting relationship with at least one adjacent flexible member to form a substantially continuous row of said flexible members along the top of said fence;
- and
- (b) means for rigidly affixing said plurality of flexible members to said fence such that each of said plurality of flexible members is prevented from rotation about a horizontal axis.
