DETAILED DESCRIPTION OF THE EMBODIMENTS

(10) The present invention provides a chafing dish and frame assembly 10, as shown in FIGS. 1 and 2, comprising a lower frame section 20 for supporting a disposable food tray 30 for holding food, and an upper frame section 40 pivotally attached to the lower frame section 20. A disposable food cover 50 is also provided which is supported by the upper frame section 40. A pivot hinge assembly 60 is also provided to pivotally connect the upper frame section 40 to the lower frame section 20. The pivot hinge 60 allows the disposable food cover 50 to be pivoted ninety degrees relative to the disposable food tray 30 from a closed position, wherein the disposable food cover 50 rests on top of the disposable food tray 30, to an open position wherein the disposable food cover 50 is pivoted upwardly to an open position so that the food in the disposable food tray 30 may be accessed.

(11) The upper frame section 40 may further provide a structural support and gripping means, which may include one or more handles 70 for pivoting the disposable food cover 50 to an open or closed position.

(12) The lower frame section 20 includes multiple support legs 22 and 24, and an upper rim 26 that extends around the four sides of the lower frame section 20, so that the rim 26 supports the food tray 30 on all four sides.

(13) The upper frame section 40 also includes an upper rim member 46 that extends around the four sides of the upper frame section 40, so that the rim 46 supports the food cover 50 on all four sides.

(14) As shown in FIG. 3, the pivot hinge 60 includes two or more pivoting hinge members 62 and 64 which are fixedly connected to the rear leg 46a of upper rim member 46. A hinge support rod 66 is connected to the rear side 26a of the upper rim member 26 of the lower frame section 20. Also, circular hinge members 62a and 64a are pivotally connected to hinge support rod 66. Hinge support rod 66 can also include a stop member 68 to support upper frame section 40 in an open position that is perpendicular to the upper rim member 46 of the upper frame section 40.

(15) The lower frame section 20 may further provide a structural support 80 for holding heat sources 90 for heating or warming the food contents in the disposable food tray 30. The heat sources 90 typically include petroleum-based gel within a can which produce a flame and are commonly referred to as sterno; however, other analogous burners may be used.

(16) In addition, the upper and lower frame sections 20 and 40 are formed of rigid aluminum, steel, iron, aluminum alloy, steel alloy, or iron alloy. The disposable food tray 30 and the disposable food cover 50 are formed of lightweight and disposable aluminum material which are inexpensive. Such aluminum food trays and aluminum food covers are readily available in the marketplace, and are commonly used for cooking food in ovens, on a stove, or over various heat sources. Other metal food trays or covers may be used such as light weight and thin aluminum, steel, iron, copper, aluminum alloy, steel alloy, iron alloy, or copper alloy.

(17) In a second embodiment, as shown in FIGS. 4, 5, and 6, a chafing dish and frame assembly 10 comprises a lower frame section 20 for supporting a disposable food tray 30 for holding food, and a detachable and nestable upper frame section 40 for supporting a disposable food cover 50.

(18) The lower frame section 20 includes multiple support legs 22 and 24, and an upper rim 26 that extends around the four sides of the lower frame section 20, so that the rim 26 supports the food tray 30 on all four sides.

(19) The upper frame section 40 includes an upper rim member 46 that extends around the four sides of the upper frame section 40, so that the rim 46 supports the food cover 50 on all four sides. A pivot hinge assembly 60 pivotally connects the upper rim member 46 to a middle attachment frame 42.

(20) Similar to as shown in FIG. 3, the pivot hinge 60 includes two or more pivoting hinge members 62 and 64 which are fixedly connected to the rear leg 46a of upper rim member 46.' A hinge support rod 66 is connected to the rear side 42a of the middle attachment frame 42, and circular hinge members 62a and 64a are pivotally connected to hinge support rod 66. Hinge support rod 66 can also include a stop member 68 to support upper frame section 40 in an open position, which is perpendicular to the upper rim member 46 of the upper frame section 40.

(21) The middle attachment frame 42 detachably connects the upper frame section 40 to the lower frame section 20 so that the upper frame section 40 is nestable within the lower frame section 20. In addition the middle attachment frame 42 is nestably secured to the lower frame section 20 preferably by clip plates 48.

(22) Also, the upper frame section 40 may further provide a structural support and gripping means, which may include handles 70 for lifting and carrying the disposable food cover 50.

(23) Furthermore, the lower frame section 20 may further provide a structural support 80 for holding heat sources 90 for heating or warming the food contents in the disposable food tray 30. The heat sources 90 typically include petroleum-based gel within a can which produce a flame and are commonly referred to as sterno; however, other analogous burners may be used.

(24) In addition, the upper, middle and lower frame sections 20, 40, 42 are formed of rigid aluminum, steel, iron, aluminum alloy, steel alloy, or iron alloy. The disposable food tray 30 and the disposable food cover 50 are formed of lightweight and disposable aluminum material which are inexpensive. Such aluminum food trays and aluminum food covers are readily available in the marketplace, and are commonly used for cooking food in ovens, on a stove, or over various heat sources. Other metal food trays or covers may be used such as light weight and thin steel, iron, copper, aluminum alloy, steel alloy, iron alloy, or copper alloy.

(25) In a third embodiment, as shown in FIGS. 7, 8, and 9, a chafing dish and frame assembly 100, comprises a lower frame section 200 for supporting a disposable food tray 300 for holding food. In addition, an upper pivot bar frame assembly 400 is provided for pivotally and hingedly attaching a disposable food tray cover 500 to the disposable food tray 300.

(26) The upper pivot bar frame assembly 400 includes a hinge support rod 420 and spring loaded clips 440. The spring loaded clips 440 pivot about the support rod 420 and clip onto and attach to the disposable food tray 300 and the disposable food tray cover 500. In this way, and as further shown in FIG. 4, the pivot bar frame assembly 400 permits the disposable food tray cover 500 to be pivoted up to ninety degrees relative to the disposable food tray 300 from a closed position, wherein said disposable food cover rests on top of said lower tray section, to an open position, wherein said disposable food cover is pivoted upwardly so that the food in said disposable food tray may be accessed.

(27) In addition, as shown in FIG. 8, the disposable food cover 500 may further include one or more attachable handles 600 for raising and lowering the disposable food tray cover 500. In further alternate embodiments, the handles 600 can include one or more spring loaded clips.

(28) In the specification the terms comprise, comprises, comprised and comprising or any variation thereof and the terms include, includes, included and including or any variation thereof are considered to be totally interchangeable and they should all be afforded the widest possible interpretation.
