  • Patent number: 5025715
    Abstract: A tripod stand structured for supporting food holding equipment over a fire pan containing a fire, or an open campfire. The tripod has three support legs, each formed of a plurality of separable sections which snap together. The upper portion of each leg is hingedly affixed to a central collar. The central collar further defines a central bore structured for retaining a vertically oriented center rigid shaft. The lower end of the center rigid shaft is structured for releasably supporting one of several food holding accessories such as a grill, a battery powered rotisserie or a shish kebob apparatus over the fire. The central collar allows the center rigid shaft to be removed or variably adjusted in height over a wide range. Temporary stationary affixment of the center rigid shaft within the central collar is made with the use of a threadably engaged L-shaped handle, one end of which extends through a threaded bore in the sidewall of the central collar.
