  • Patent number: 5971408
    Abstract: A vertically adjustable wheel assembly for movably supporting an appliance cabinet or the like upon a supporting surface includes a housing, a supporting bracket, a wheel unit, an adjusting rod, an adjusting screw and various elongated mounting members. The wheel unit is defined by a pair of spaced rollers that are interconnected by a reduced diametric portion. The wheel unit is rotatably attached to the support bracket by an axle member, while the adjusting rod is also mounted for rotary movement by the support bracket. The support bracket is pivotally mounted to the housing, with both the wheel unit and the adjusting rod being permitted to rotate relative thereto. The adjusting screw extends through a frontal portion of the housing and it is threadably connected to the adjusting rod such that rotation of the screw causes pivoting of the support bracket relative to the housing and movement of the wheel assembly between fully extended and fully retracted positions.

  • Patent number: 5765379
    Abstract: It is already known that heat insulating elements, e.g. in refrigerators, may be more efficient if they are sealingly encapsulated and subjected to a high vacuum. Based on theoretical considerations in connection with foam having small cells it has been relevant to use a vacuum of the magnitude of 0.001 mbar and hermetical sealing of the elements. According to the invention it has been found that practically well usable results are achievable at much higher pressures, viz. in a range about 1 mbar, which is much easier to produce. Consequently, a further simplification can be obtained by renouncing the hermetical sealing and relying on an only "almost tight" sealing, combined with the use of an operationally active vacuum pump provided in each apparatus unit.

The refrigeration system maintains the chamber at a substantially constant, ultra low temperature, such as within the range of about -50.degree. C. to -90.degree. C. Short term items may be stored in and accessed from an upper portion of the chamber by the upper door without causing the very cold air in the freezer chamber from spilling out the lower portion of the chamber. Long term items may be stored in the lower portion of the chamber and accessed by the lower door. A horizontal mullion is mounted to the freezer side walls and extends between the two doors to provide a seal for respective lower and upper edges of the two doors. A self-regulating heater strip is disposed within the mullion between upper and lower resilient sealing bulbs extending horizontally to prevent condensation build up in the mullion area.

  • Patent number: 5725294
    Abstract: A refrigerator includes a front face surrounding the front openings of the storage compartments. Operation of the refrigerator tends to cause some portions of the face to be colder than the dew point temperature of the surrounding air. Moisture in the surrounding air tends to condense on such colder than dew point portions. Sheets of aluminum foil are in intimate contact with the inside of the case, extend along those portions of the face subject to condensation and project onto adjacent areas of the case which are warmer than the dew point temperature. This keeps the temperature of those portions subject to condensation above the dew point temperature. Portions of the doors, such as the adjacent peripheral walls of doors on multi-compartment units, also may tend to be below the dew point temperature. Sheets of aluminum foil are positioned in intimate contact with the inside of those portions of the doors and project onto adjacent areas of the doors which are warmer than the dew point temperature.

The strip front wall extends inward from the case flange to a point inward of the liner wall and a side wall extends rearward to overlap the liner wall. A bifurcated edge of the strip receives the case flange. The strip side wall is return bent to form an inner wall engaging the inner surface and a resilient finger engaging the outer surface of the liner wall. A resilient mullion, connecting the adjacent inner lateral walls of the liners, has a front wall extending across the space between the liners and a side wall projecting rearward from each edge of the front wall to overlap the liner lateral wall.

  • Patent number: 5702168
    Abstract: A damping apparatus for a refrigerator has a first space formed in the interior of a cabinet of the refrigerator, a second space which is separated from the first space by a stopping protrusion and is in communication relation with the first space, a first damping member expandably mounted in the second space, and a protrusion formed on one side of a door for closing the first damping member. When the door is pivoted to be closed, the protrusion closes the first damping member so that the air in the interior of the first damping member is exhausted outside, dampening the reactive force generated in a compartment. On the other hand, when the door is pivoted to be opened, the second damping member is pressed so that the force by the negative pressure in the interior of the compartment is dampened. The damping apparatus for a refrigerator can dampen the force needed when the door is opened or closed.

  • Patent number: 5618089
    Abstract: A device for the swiveling movement of a sheet is described. A stationary bearing part supports an articulated part in a swivelable manner. The articulated part supports the sheet and is movable about a substantially horizontal swivel axis. The sheet is accordingly movable between a lowered position and a raised position, the direction of this movement being determined by a vertical swiveling plane. Energy accumulators, e.g., pneumatic springs, serve as auxiliary lifting means for raising the sheet. These energy accumulators have two connection ends which are loaded in opposite directions and determine the effective direction of force of the energy accumulator. For the purpose of an advantageous arrangement of the device which economizes on space, it is proposed that the energy accumulator be arranged with its effective direction of force substantially transverse to the swiveling plane of the sheet. The two connection ends of the energy accumulator are constructed as three-dimensionally acting rolling joints.
