Abstract

A multi-piece cooktop compatible with various firepits for creating a firepit assembly.

Description

FIELD OF THE INVENTION

The present invention relates to outdoor cooking and outdoor fire pits. More particularly, the invention relates to a multi-piece cooktop that is configured for use with fire pits and accessories of various configurations.

BACKGROUND OF THE INVENTION

Outdoor fire pits have, in the past, been permanent fixtures built from rock, concrete, metals, or other resilient and heavy materials. Often a fire pit is built directly on the ground and is not readily portable. Recently, fire pits have been developed that may be somewhat portable and may be used to provide warmth for users surrounding the fire pit. It is desirable to increase the functionality of a fire pit as well as keep production costs low.

SUMMARY OF THE INVENTION

The fire pit assembly of the invention allows for a user to utilize a fire pit for cooking by utilizing a two piece cook top adapted to be received on the fire pit. In one embodiment, the two piece cook top is configured so that it may be provided for at least two differently sized fire pit products.

In greater detail, an outer donut style cook top is designed to fit onto a fire pit or onto a screen accessory of a fire pit. The cook top includes a cook to top ring and a center piece. The center piece, or donut hole, of the cook top is designed to fit in the hole of the cook top ring. The two piece design offers many benefits, including easy access to tend the fire of the fire pit, easy access to the fire pit to add wood, an ability to easily change cooking surfaces, e.g., griddle, grate, pan, sear plate, dutch oven, etc. The outer donut not only provides additional cooking area, it also helps contain grease, provides a cooler area for food resting, and, with the supplied trivet provides a large serving area. The cook top is designed to fit various components including a relatively smaller fire pit, a relatively smaller fire pit screen, a relatively larger fire pit, and a relatively larger fire pit screen.

In greater detail, a fire pit and multi-piece cooktop assembly includes a fire pit having a fire pit body defining a chamber that is partially defined by an inner chamber wall having an upper end and defining a plurality of apertures, and partially defined by a fuel grate defining a plurality of apertures. The fire pit has an outer wall having an upper end that surrounds the inner chamber wall. The fire pit has a top panel between the upper end of the inner chamber wall and the upper end of the outer wall. The fire pit body is supported by a stand having a support ring supported by a plurality of legs.

A ring is located above the inner chamber wall and above the top panel. The ring has an inner vertical ring portion and an outer horizontal ring portion.

An accessory may be provided. The accessory has an accessory body. The accessory body has an upper surface, a lower surface and a width. In one embodiment, the accessory is a screen member. The lower surface may be received within the upper end of the inner chamber wall of the chamber.

A multi-piece cooktop is provided having an inner cooking member received within a ringed cooking member. The inner cooking member defines a cooking surface having a width, and a bottom surface having a width. The width of the cooking surface may be a diameter. The inner cooking member has an outer edge between the cooking surface and the bottom surface. In one embodiment the cooking surface is circular. The cooking surface preferably defines a plurality of alternating raised members and channels. The width of the bottom surface is smaller than the width of the cooking surface such that the outer edge has an outward slant. The outward slant of the outer edge may be approximately 15-60 degrees from vertical. In some embodiments the outward slant is about 30 degrees from vertical. A handle extends upwardly and outwardly from the outer edge of the inner cooking member.

The ringed cooking member has a base defining a surrounding cooking surface and a surrounding bottom surface. The surrounding cooking surface defines an inner cooking surface edge defining a cooking surface orifice. The ringed cooking member has a circular perimeter. The surrounding cooking surface defines an outer cooking surface edge. The surrounding cooking surface is surround by upwardly extending sides defining a rim. A first handle and a second handle extend above the rim. A surrounding channel is between the outer cooking surface edge and the upwardly extending sides. The surrounding channel defines an inwardly sloping inner surface. In one embodiment, the cooking surface orifice is circular. In one embodiment, cooking surface orifice is centered within the surrounding cooking surface. The surrounding bottom surface defines a bottom surface inner edge that surrounds a bottom surface orifice. An orifice perimeter extends from the inner cooking surface edge of the cooking surface orifice to the bottom surface inner edge of the bottom surface orifice. The cooking surface orifice is larger than the bottom surface orifice such that the orifice perimeter has an outward slant. The outward slant of the orifice perimeter may be approximately 15-60 degrees from vertical. In some embodiments, it is about 30 degrees from vertical.

The outer edge of the inner cooking member is sized to be matingly received within the orifice perimeter of the ringed cooking member. When the outer edge of the inner cooking member is matingly received within the orifice perimeter of the ringed cooking member, the surrounding cooking surface of the inner cooking member and the cooking surface of the ringed cooking member are substantially co-planar. “Substantially co-planar” is defined as having a deviation of less than ⅛″ inch;

The multi-piece cooktop is sized to be received on the upper surface of the accessory body. The bottom surface inner edge of the bottom surface orifice of the ringed cooking member is sized to be received on the ring of the firepit and the inwardly sloped inner surface of the surrounding channel is sized to be received on the ring of the firepit.

Therefore, it can be seen that the multi-piece cooktop of the invention is adapted for use on fire pits of various configurations, both with and without an accessory such as a screen member.
