  • Patent number: 11725453
    Abstract: A barricade used to obstruct the gap between a garage door, weather stripping, a threshold surface and a door frame. The barricade successfully prevents pests from breaching the barricade. The barricade uses a spring assist with low displacement force in order to conform to the changing downward or upward angle when a garage door is being operated. It also includes smooth ceramic or rubber that is magnetized to prevent chaffing to the garage door surface. This barrier stays in-place or rotates relative to the garage door face when encountering foreign objects in the path of the moving garage door. Alternatively, the barriers may be constructed of overlapping and/or abutting material configured to obstruct gaps at door frames and/or at threshold surfaces where a weather stripping and/or weather-stripping bulb provide inadequate obstruction.

  • Publication number: 20190261620
    Abstract: A novel barricade used to seal the gap between a door, weather stripping and a door frame. The barricade successfully prevents pests or rodents from breaching the barricade and entering into the garage or other area. The barricade uses a spring assist with low displacement force in order to conform to the changing downward or upward angle when a garage door is being operated. It also includes magnetized rubber seals to prevent chaffing to the garage door surface. This barrier stays in-place and is unable to be pulled off of the garage door face by pests or rodents and remains effective for long durations.
