  • Publication number: 20030029126
    Abstract: A spring clip member for a storage building is provided. The spring clip member is adapted to be snap-fit to an elongate structural member of the storage building. The spring clip member includes a first portion shaped to follow a first contour of the elongate structural member, a second portion extending from said first portion and shaped to follow a second contour of the elongate structural member, a third portion extending from said second portion and shaped to follow a third contour of the elongate structural member, and a deflectable portion extending from said third portion and adapted to elastically deflect and to securely engage the elongate structural member. The spring clip member may be, for example, part of a gable member adapted to be snap-fit to an upper panel channel of a storage building, or, alternatively, part of a debris deflector adapted to be snap-fit to a lower panel channel of a storage building.

  • Patent number: 5503408
    Abstract: A seal assembly is mounted on a shaft in sealing relationship to provide a sealed chamber in a housing from which the shaft extends. The seal assembly includes a unitary annular seal body attached to an annular retainer. The seal body includes three radial sealing lips in engagement with the shaft. A primary lip is adjacent the sealed chamber and provides the primary fluid seal. A secondary lip is rearward of the primary lip and keeps the primary lip aligned with the shaft. A rearward lip excludes environmental contaminants from entering the sealed chamber.
