Embodiments disclosed herein generally relate to grates used on a gas-heated cooking range, as well as a multi-grate system for a range or other cooktop.
Gas cooking ranges are well known for home and commercial kitchens. Many different configurations are known in the art, but a couple of major designs predominate. The first is shown in
In contrast, configurations like that shown in
Accordingly, it is desirable to provide a grate that, on its own and assembled with other grates on a range, provides both the heating advantages of the traditional configuration shown in
In one aspect, embodiments disclosed herein may include a first grate for a cooking range, said grate including a bowl with a rectilinearly-bounded border region which border is at least ten inches long or wide; a set of eight tangs protruding upward from and extending distally from the border region generally toward a central region above the bowl; and a set of at least six nubs protruding upward from the border region and disposed alternatingly between at least six of the eight tangs; where an uppermost surface of each of the tangs and an uppermost surface of each of the nubs together forms a non-contiguous surface along a common plane that is disposed above the bowl including the border region of the bowl; wherein the uppermost surfaces of the tangs and the nubs are configured and disposed in proximity to each other such that a five-inch diameter planar circle is positionable anywhere upon said uppermost surfaces in a manner preventing tipping by maintaining at least three points of contact, at least two lines of contact, at least one point and at least line of contact, or any other combination of points and/or lines of contact, so that the five-inch diameter planar circle remains at least substantially coplanar with the common plane; wherein the entire uppermost surface of at least one of the tangs or at least one of the nibs is narrower than its lowermost surface, thereby providing a tapered transverse sectional profile for said at least one of the tangs or at least one of the nubs; and wherein the distal end of at least one of the tangs is narrower than the proximal end of the tang.
In one aspect, embodiments disclosed herein may include a first grate for a cooking range, said grate including a bowl with a rectilinearly-bounded border region which border is at least ten inches long or wide; a set of eight tangs protruding upward from and extending distally from the border region generally toward a central region above the bowl; and a set of at least six nubs protruding upward from the border region and disposed alternatingly between at least six of the eight tangs; where an uppermost surface of each of the tangs and an uppermost surface of each of the nubs together forms a non-contiguous surface along a common plane that is disposed above the bowl including the border region of the bowl; and wherein the uppermost surfaces of the tangs and the nubs are configured and disposed in proximity to each other such that a five-inch diameter planar circle is positionable anywhere upon said uppermost surfaces in a manner preventing tipping by maintaining at least three points of contact, at least two lines of contact, at least one point and at least line of contact, or any other combination of points and/or lines of contact, so that the five-inch diameter planar circle remains at least substantially coplanar with the common plane.
In another aspect, embodiments disclosed herein may include a multi-grate range, such as—for example—a gas cooking range including burners, with a plurality of grates as described and/or illustrated herein.
In certain embodiments, the uppermost surface of at least one tang or at least one nub is narrower than its lowermost surface, thereby providing a tapered transverse sectional profile for said at least one tang or at least one nub.
In further embodiments, a multi-grate system for a gas cooking range includes a plurality of grates with each grate having at least one edge abutting at least one edge of another grate; wherein at least a first grate and a second grate of the plurality of grates each includes: a bowl including a rectilinearly-bounded border region outwardly defining the edges of each grate; a set of eight tangs protruding upward from and extending distally from the border region generally toward a central region above the bowl; and a set of at least six nubs protruding upward from the border region and disposed alternatingly between at least six of the eight tangs; where an uppermost surface of each of the tangs and an uppermost surface of each of the nubs are aligned so as to form a non-contiguous surface along a common plane that is disposed above the bowl; and wherein the uppermost surfaces of the tangs and the uppermost surfaces of the nubs are configured and disposed in proximity to each other such that a five-inch diameter planar circle is positionable anywhere upon said uppermost surfaces in a manner preventing tipping by maintaining at least three points of contact, two lines of contact, a point and a line of contact, or any combination thereof, so that the five-inch diameter planar circle remains at least substantially coplanar with the common plane in any position atop the uppermost surfaces of the plurality of grates.
Various embodiments are described below with reference to the drawings in which like elements generally are referred to by like numerals. The relationship and functioning of the various elements of the embodiments may better be understood by reference to the following detailed description. However, embodiments are not limited to those illustrated in the drawings. It should be understood that the drawings are not necessarily to scale, and in certain instances details may have been omitted that are not necessary for an understanding of embodiments disclosed herein, such as—for example—conventional fabrication and assembly. However, in the present application, at least
The present disclosure sets forth individual grates and a multi-grate system for a cooking range, wherein construction of the tangs and nubs of each grate are aligned with each other in a manner providing a non-contiguous surface along a common plane. The common plane is provided by the uppermost surfaces of the tangs and nubs upon which the bottom of a cooking vessel (e.g., stock pot, skillet, saucepan, griddle, etc.) rests. Existing grates typically require precise placement of a cooking vessel to keep it balanced and level on the grate surface, which is formed by the tangs or fingers that define the grate. Prior grates with radially disposed tangs (e.g., as in
The invention is defined by the claims, may be embodied in many different forms, and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey enabling disclosure to those skilled in the art. As used in this specification and the claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.
The terms “proximal” and “distal” are used herein with reference to the border region of a single grate that defines its outer boundary, where the proximal end of a tang is mounted onto the border. The tang extends above the border and distally toward the center of the grate. The terms “about,” “substantially,” “generally,” and other terms of degree, when used with reference to any volume, dimension, proportion, or other quantitative or qualitative value, are intended to communicate a definite and identifiable value within the standard parameters that would be understood by one of skill in the art, and should be interpreted to include at least any legal equivalents, minor but functionally-insignificant variants, standard manufacturing tolerances, and including at least mathematically significant figures (although not required to be as broad as the largest range thereof). The phrase “substantially co-planar” is used to mean that the item addressed (e.g., a planar disc of a given diameter-such as a bottom surface of a cooking vessel) will tip by no more than a 10 degree angle, and preferably by no more than a 5 degree angle relative to the plane of reference. Co-linear means disposed along a common straight line, such as co-linear tangs and co-linear nubs that are disposed along a common imaginary axis/line that goes through/across a center-point of a grate.
One embodiment of a multi-grate range 400 is described with reference to
Notably, the uppermost surfaces of the tangs 404 and the nubs 410 are configured and disposed in proximity to each other such that a planar circle is positionable anywhere upon said uppermost surfaces in a manner preventing tipping of that planar circle (e.g., the bottom contact surface of a cooking vessel) by maintaining at least: three points of contact, two lines of contact, a point and a line of contact, or any combination thereof. As a result, and as illustrated in
Stated differently, in every contact position over a single grate and over a multi-grate array of a cooking range, a planar circle (e.g., the bottom surface of a cooking vessel) will always contact and rest upon some combination of linear and/or point surfaces of tangs and/or nubs sufficient to substantially prevent it from tipping because an uppermost surface of each nub and/or tang is within five inches of a nearest uppermost surface of another nub and/or tang (where substantially preventing tipping refers to less than ten degrees, preferably less than five degrees, and more preferably between level and two degrees). For the embodiments shown, this is applicable to a square or a non-square rectangular configuration of a rectilinear grate with dimensions of up to 18 inches by 18 inches, with a grate size preferably of at least 10 inches by 10 inches. This is further illustrated in
In order to provide desirable efficiency of heating effectiveness by convection from an underlying burner and open space between the burner and an underside of a cooking vessel, a distal end portion of each tang is connected to no more than one distal portion of one other tang. This is shown in each of the three different embodiments of tang and nub configurations illustrated in
A connected-tang grate embodiment 802 is shown in
Likewise, in the grate embodiment 902 of
Another means of increasing the open area between a burner and the underside of a cooking vessel resting on the common plane is to decrease the surface area of the uppermost surfaces of the tangs. This is done in the illustrated embodiments by providing a tapered surface as illustrated, which includes a robust construction for durability with reference to a broader base and mounting to the lower/concave surfaces of the bowl. The tapering can achieve the same or similar functional advantages while being configured differently than the “house-shaped” taper illustrated (e.g., hemispherically rounded, ogive, including more or fewer chamfered or otherwise angled surfaces, parabolic etc.).
As shown in
In the illustrated embodiments of
Those of skill in the art will appreciate that embodiments not expressly illustrated herein may be practiced within the scope of the claims, including that features described herein for different embodiments may be combined with each other and/or with currently-known or future-developed technologies while remaining within the scope of the claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation unless specifically defined by context, usage, or other explicit designation. It is therefore intended that the foregoing detailed description be regarded as illustrative rather than limiting. And, it should be understood that the following claims, including all equivalents, are intended to define the spirit and scope of this invention. Furthermore, the advantages described above are not necessarily the only advantages of the invention, and it is not necessarily expected that all of the described advantages will be achieved with every embodiment. In the event of any inconsistent disclosure or definition from the present application conflicting with any document incorporated by reference, the disclosure or definition herein shall be deemed to prevail.
This application is a continuation application which claims priority under 35 USC § 120 to U.S. application Ser. No. 16/431,465, filed Jun. 4, 2019, which is incorporated by reference herein in its entirety.
