Spring balanced chafing dish
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.

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.
