Description

    RELATED APPLICATIONS
  • [0001]
    The present application is a continuation of U.S. patent application Ser. No. 10/310,358, filed Dec. 5, 2002, now U.S. Pat. No. ______.
  • FIELD OF THE INVENTION
  • [0002]
    The present invention relates generally to conditioning enclosures and more specifically to a universal access port for conditioning enclosures, structured to receive numerous insertable devices.
  • BACKGROUND OF THE INVENTION
  • [0003]
    There are several conditioning enclosures on the market, which disclose an opening created in a side thereof. A conditioning enclosure is defined as an oven, freezer, incubator, burn-in chamber, environmental test chamber, shaker, or any other device that stresses, modifies, or conditions an item inserted therein. Pat. No. 4,854,726 to Lesley et al. discloses a thermal stress screening system. An exposure chamber is connected to a cabinet with a pair of insulated delivery hoses. Pat. No. 4,949,031 to Szasz et al. discloses an environmental stress screening apparatus for electronic products. A product carrier pallet is inserted into an opening formed in an environmental test chamber. Pat. No. 5,147,136 to Hartley et al. discloses temperature cycling test chambers. A portion of the wall is rotable between two different test chambers.
  • [0004]
    Accordingly, there is a clearly felt need in the art for a universal access port formed in a side of a conditioning enclosure, which has a specific size and shape to receive windows, wire access devices, bulkhead connectors, manual manipulation devices, doors, junction boxes, shelves, racks, drawers, blowers, slave test chamber, and other insertable devices.
  • SUMMARY OF THE INVENTION
  • [0005]
    The present invention provides a universal access port for conditioning enclosures, which receives standard sized insertable devices, thus increasing the versatility of one or more conditioning enclosures. At least one universal access port allows a first conditioning enclosure to have expanded capacity by connecting additional conditioning enclosures to the first conditioning enclosure to retain the additional parts for testing. The additional conditioning enclosure would be connected with a junction device inserted into the universal access ports of each conditioning enclosure.
  • [0006]
    The additional conditioning enclosures are used as auxiliary units and their functionality need not be the same as the first conditioning enclosure. For example, the capacity for performing some types of temperature testing is increased without the cost of additional conditioning enclosures having the same function as the first conditioning enclosure. The universal access port also provides modular assembly of a group of conditioning units each having different functions. The function of each different conditioning unit may be activated when appropriate.
  • [0007]
    Each universal access port includes a specific size opening that is formed through a wall of a conditioning enclosure and located at a specific distance from a floor or mounting surface of the conditioning enclosure. The opening preferably has a rectangular shape, but other shapes may also be used. When not in use, the universal access port is covered with a sealing panel. Insertable devices may be efficiently inserted and removed from the universal access port, including the sealing panel. A perimeter of an insertable device is sized to be sealably inserted into the universal access port. Each insertable device preferably seals with an exterior and an interior wall of the conditioning enclosure. Some insertable devices include fixture devices, windows, manual manipulation devices, junction devices, hinged access doors, wire access devices, hydraulic connection devices, temperature modifying devices, air circulation devices, gas insertion devices, blower devices, or any other appropriate insertable device.
  • [0008]
    Accordingly, it is an object of the present invention to provide at least one universal access port in a conditioning enclosure, each universal access port having a specific opening size located a specified distance from a floor or mounting surface of the conditioning enclosure.
  • [0009]
    Finally, it is another object of the present invention to provide a plurality of insertable devices that are sized to be inserted into a universal access port formed in a conditioning enclosure.
  • [0010]
    These and additional objects, advantages, features and benefits of the present invention will become apparent from the following specification.
