Abstract
A hot food stand utilizes heat lamps to keep food warm. The lamps are automatically activated when food is placed on a pressure sensitive support positioned beneath the lamps. A modified embodiment of the invention senses the quantity and positioning of food on the support and activates additional heat lamps if needed.
Claims2
A hot food stand, comprising:
- a. housing means;
- b. support plate means mounted on a floor portion of said housing means and being operable to support a quantity of food positioned thereon;
- c. a plurality of heating lamps mounted in a topmost portion of said housing means, said heating lamps serving to radiate heat downwardly on said food, thereby to effect a warming thereof;
- d. a plurality of pressure sensitive switches, said switches being normally retained in an open condition by spring biasing means, said spring biasing means including individual springs for each of said plurality of pressure sensitive switches, each of said springs having different spring constants to thus vary a pressure required to close each of said switches, a first of said switches when closed activating a first of said plurality of heating lamps as a result of food being placed at a first end of said support plate means, a second of said switches when closed activating a second of said plurality of heating lamps as a result of food being placed at a second end of said support plate means.

- e. spring means for mounting said support plate means thereon, said spring means including a plurality of individual springs with each of said springs having different spring constants, whereby a first end of said support plate means will move downwardly at a different rate than a second end of second support means, thus to close individual ones of said plurality of pressure sensitive switches at different times and depending upon a sensed pressure upon said plate means.
