  • Publication number: 20100025156
    Abstract: An emergency evacuation system includes one or more walkways that extend from a first multi-story building, at designated floor levels above the ground floor, to an adjacent multi-story building. The emergency walkway has a series of interconnecting, telescopically extendable sections that are normally stowed in a retracted arrangement within the first building. When the emergency walkway is deployed, safety walls raise and lock into an operable, vertical position along the entire length of the walkway, from the first building to the adjacent building. The system may include a rotatable base at the first building to allow adjusted angular positioning of the extended walkway so that the opposite end of the emerging walkway docks at the desired location on the side of the adjacent building. Emergency access to both the first building and the adjacent building, at opposite ends of the walkway, is normally closed and only opens when the emergency evacuation system is deployed.

  • Publication number: 20100012430
    Abstract: The claimed work platform system, alternatively dubbed by the inventor as “Miniscaffold”, provides a compact, versatile, and portable method of supporting workers engaged in various elevated construction or maintenance activities. The claimed work platform rides upon a number of locking floor casters. Each floor caster is mounted to a removable, telescoping support which may be readily relocated inward to accommodate access through narrow aisles or outward to enhance the platform's stability. Each telescoping support is also fitted with an individual jack mechanism to compensate for the inevitable variations in ground or floor elevation typical at construction or work sites. The “Miniscaffold” is also constructed from interlocking square tube members which enhance the work platform's stability and thus eliminate the obtrusive and cumbersome diagonal supports found on most scaffolding.
