Abstract: A food warmer has a cover hinged on a flame by a pair of side hinges for rotation around an axis between a closed position and a fully open position, with there being present between the cover and the frame at least one spring for opposing the rotation moment generated by the weight of the cover. Each hinge includes a pivot element on the frame and a fork, shaped bracket on the cover releasably engagable with and rotatable on the associated pivot. A spring contained in at least one of said pivots reacts on the fork engaged therewith to oppose the rotation movement generated by the weight of the cover.

Abstract: A food warmer (10) has a cover (14) hinged on a frame (11) by means of opposing side hinges (16,17,18,19,22,23) for rotating it around an axis of rotation between a closed position and a fully open position. At least one of the S hinges comprises coupling means (16,18) between the cover and the frame which rotate integrally with the cover against the action of reaction means (20) mounted on the frame. In this manner the action of the reaction means supplies virtual balancing of the moment produced by the weight of the cover.
