Abstract

A chafing dish includes a pan, a cover hingedly connected to the pan through a hinge shaft, a plurality of cover arms, each cover arm having one end secured to the hinge shaft and other end to the cover, and a counter balance member which encircles a part of the hinge shaft and is secured in position at both ends in a hinge assembly, thereby enabling the counter balancing of the cover at any angle from the closed state of the cover.

Claims (63)

1. A chafing dish, comprising:

a pan;

a cover;

a hinge shaft coupled to the pan and the cover;

a first cover arm coupled to a first end of the hinge shaft and to the cover;

a second cover arm coupled to a second end of the hinge shaft and to the cover;

a counter balance member encircling a part of the hinge shaft;

a hinge assembly coupled to a first end and a second end of the counter balance member, the counter balance member having a torsion enabling a counter balancing of the cover at any angle from a closed state to an unstressed state; and

an externally adjustable balance adjustment mechanism coupled proximately to the first end of the hinge shaft, comprising a bearing support for the hinge shaft, the bearing support comprising a balance adjuster and a stop adjuster protruding through end caps of the hinge assembly, whereby allowing adjustment of the chafing dish without disassembly.

2. The chafing dish of claim 1 , wherein the counter balance member comprises a torsion spring encircling the part of the hinge shaft.

3. The chafing dish of claim 1 , wherein the pan comprises a water pan.

4. The chafing dish of claim 3 , further comprising a food pan nested inside the water pan.

5. The chafing dish of claim 1 , further comprising a cover handle for raising and lowering the cover.

6. The chafing dish of claim 1 , further comprising a hinge support frame coupled to the hinge assembly and the pan.

7. A chafing dish, comprising:

a pan;

a cover;

a hinge shaft coupled to the pan and the cover;

a first cover arm coupled to a first end of the hinge shaft and to the cover;

a second cover arm coupled to a second end of the hinge shaft and to the cover;

a counter balance member encircling a part of the hinge shaft; and

a hinge assembly coupled to a first end and a second end of the counter balance member, the counter balance member having a torsion enabling a counter balancing of the cover at any angle from a closed state to an unstressed state,

wherein a first end of the first cover arm is coupled to the hinge shaft through fasteners, wherein a second end of the first cover arm is welded to the cover.

8. The chafing dish of claim 7 , wherein the fasteners comprise thumb screws.

9. A chafing dish, comprising:

a pan;

a cover;

a hinge shaft coupled to the pan and the cover;

a first cover arm coupled to a first end of the hinge shaft and to the cover;

a second cover arm coupled to a second end of the hinge shaft and to the cover;

a counter balance member encircling a part of the hinge shaft; and

a hinge assembly coupled to a first end and a second end of the counter balance member, the counter balance member having a torsion enabling a counter balancing of the cover at any angle from a closed state to an unstressed state,

wherein the first end of the counter balance member is coupled to a balance adjuster and the second end of the counter balance member is coupled to a shaft anchor.

10. A chafing dish, comprising:

a pan;

a cover;

a hinge shaft coupled to the pan and the cover;

a first cover arm coupled to a first end of the hinge shaft and to the cover;

a second cover arm coupled to a second end of the hinge shaft and to the cover;

a counter balance member encircling a part of the hinge shaft;

a hinge assembly coupled to a first end and a second end of the counter balance member, the counter balance member having a torsion enabling a counter balancing of the cover at any angle from a closed state to an unstressed state; and

a condensate drain tube coupled to the cover and a condensate catch trough coupled to the pan, wherein condensate from the cover is able to drain from the condensate drain tube to the pan through the condensate catch trough.

11. A chafing dish, comprising:

a pan;

a cover;

a hinge shaft coupled to the pan and the cover;

a first cover arm coupled to a first end of the hinge shaft and to the cover;

a second cover arm coupled to a second end of the hinge shaft and to the cover;

a counter balance member encircling a part of the hinge shaft;

a hinge assembly coupled to a first end and a second end of the counter balance member, the counter balance member having a torsion enabling a counter balancing of the cover at any angle from a closed state to an unstressed state; and

a balance adjuster and a stop adjuster for supporting the hinge shaft.

12. The chafing dish of claim 11 , further comprising:

a balance set screw for holding a position of the stop adjuster; and

a stop set screw for holding a position of the balance adjuster.

13. A chafing dish, comprising:

a pan;

a cover;

a hinge shaft coupled to the pan and the cover;

a first cover arm coupled to a first end of the hinge shaft and to the cover;

a second cover arm coupled to a second end of the hinge shaft and to the cover;

a counter balance member encircling a part of the hinge shaft;

a hinge assembly coupled to a first end and a second end of the counter balance member, the counter balance member having a torsion enabling a counter balancing of the cover at any angle from a closed state to an unstressed state; and

a shaft stop and a stop adjuster pin for limiting an opening of the cover to the unstressed state of the counter balance member.
