Patent attributes
An improved pet barrier has first and second spaced-apart vertical poles and one or more horizontally oriented fences that are affixed to the poles. At least the top ends of the poles terminate in resilient, convexly curved feet. The feet have contact surfaces that are approximately hemitoroidal in shape. Each pole may have a tube and an elongate upright extending out of the tube and may have a coarse adjustment mechanism that permits the vertical insert to extend out of the top end of the tube by one of several preselected heights. Each pole may have a fine adjustment mechanism including a lead screw and a nut that rotates on a groove formed near the end of the pole tube. A fence clamp clamps upper and lower cross bars of the fence to the clamp using a single threaded fastener, the clamping action also affixing the fence to the pole.
