Patent Abstract:
The present invention relates to a lid support and positioner that is quite versatile in how it can cooperate with the handle of cooking vessels to overly the handle, and to underly, engage and provide support for a cover or lid of the cooking vessel that is positioned off center relative to an upward opening cooking chamber of the vessel to permit the cooking chamber to breathe so as to minimize or prevent bubble-over or boil-over of cooking fluids. When used with cooking vessels that have elongate handles, the lid support and positioner may be adjustable positioned on the length of the handle to underly, engage and support a peripheral portion of an off-center cover or lid at a range of locations where the lid selectively covers/uncovers different proportions of the cooking chamber to thereby regulate and control the cooking temperature within the cooking chamber.

Full Description:
BACKGROUND 
       [0001]    Cooking vessels such as pots and pans that have upstanding side walls surrounding upwardly opening cooking chambers in which foods are heated and cooked typically contain cooking fluids that can bubble over or boil over, especially when the cooking chambers are fully covered, which can cause cooking temperatures within the cooking chambers rising to inappropriate magnitudes. Leaving the upwardly opening cooking chambers completely uncovered can also permit cooking fluids to splatter about. Accordingly, in many situations, neither fully covered nor fully uncovered cooking chambers provide desirable results. 
         [0002]    A technique commonly used by cooks to eliminate bubble-over, and to regulate or control temperature within the cooking chamber of a cooking vessel being heated is to adjustably position the cover or lid of the cooking vessel off-center, so that, during heating or cooking, only a selected portion of the upwardly opening cooking chamber of the vessel is covered, and a remaining portion of the cooking chamber is deliberately left uncovered. This technique, when used during cooking, provides a simple and straightforward technique for regulating and controlling the temperature within the cooking chamber, and permits bubble-over or boil-over to be minimized. 
         [0003]    A problem with positioning a cover or a lid off-center (which term is used herein to mean “extending substantially horizontally atop only a portion of the rim or top edge of a vessel&#39;s cooking chamber”) is that the portion of the cover or lid that extends outside and beyond the periphery of the vessel&#39;s cooking chamber is entirely unsupported—meaning that it extends in a cantilevered fashion—whereby the cantilevered and off-center cover or lid may fall off, or can easily be accidentally knocked or brushed completely off of the associated cooking vessel, which may cause hot cooking fluid such as hot cooking grease and the like to be splattered or spilled onto a floor and/or near to a stove or cooktop that is being used to heat the cooking vessel. 
         [0004]    U.S. Pat. No. 2,879,915 which issued Mar. 31, 1959 to Joseph R. Medor (the disclosure of which us uncorporated herein by reference) recognizes the need for providing underlying support for an off-center lid situated atop a cooking vessel. However, the Medor patent addresses this need by proposing a metal clip that is designed to extend into, and to overlie an interior portion of the cooking chamber of a cooking vessel. The proposed clip of Medor underlies and is designed to offer added support for only the part of and off-center cover or lid that overlies the vessel&#39;s cooking chamber, and does nothing to underlie and support the part of an off-center cover or lid that extends in a cantilevered fashion beyond the perimeter of the vessel&#39;s cooking chamber. 
         [0005]    A significant drawback of the Medor clip is that it overlies only an inside portion of a cooking chamber of the cooking vessel on which it is installed. The clip is not intended to underlie and support any part of a off-center cover or lid that extends outside of and beyond the perimeter of the cooking chamber of a cooking vessel—which is the part of a off-center cover of lid that is most likely to be accidentally struck and unintentionally brushed off the associated cooking vessel. 
         [0006]    A further drawback of the Medor clip is that it is not intended to aid in adjustably positioning an off-center lid through a wide range of movement so that a significant portion of the area of a cover or lid can extend outside the perimeter of the cooking chamber of a cooking vessel while the cover or lid is still being supported by the relatively short Medor clip. 
         [0007]    Inasmuch as the Medor clip is intended to be used to overlie a cooking chamber where hot grease and cooking fluids are likely to be bubbling and splattering about, clearly the clip is intended to be grasped, repositioned and adjusted only when the associated cooking vessel is out of service, not while cooking fluids are being heated and are bubbling about—i.e., not while cooking is underway. 
         [0008]    Another drawback of the Medor clip is its likelihood of becoming covered with grease and other splatter, necessitating that the clip frequently be removed to be cleaned. 
         [0009]    Still another drawback of the Medor clip is that it in no way makes use of the handle of the cooking vessel on which the clip is installed to underlie and to provide support for an off-center cover or lid. Further, the clip proposed by Medor is designed to take a rigid form that offers no resilience and no capability to adjustably grip cooking vessel portions of differing size, and having no memory for returning to an initial shape after being deformed temporarily to grip a cooking vessel handle or the like. 
         [0010]    Neither recognized in nor appreciated by the Medor patent is the fact that the significant degree of temperature control can advantageously be obtained by modifying and adjusting the covered and uncovered areas of the cooking chamber of a cooking vessel. The patent neither recognizes nor suggest taking advantage of the fact that, by increasing the size of an uncovered area of a cooking chamber, cooking temperature can easily be decreased because more heat is permitted to escape; or that, by decreasing the size of the uncovered area of a cooking chamber, an increase in cooking temperature can easily be obtained.

     DESCRIPTION 
       [0039]    Referring to  FIGS. 1-2, 4 and 6-8 , a one piece lid support and positioner  100  is shown that depicts one possible and preferred embodiment of the invention. As will be readily apparent to and understood by those who are skilled in the art, a lid support and positioner that embodies features of the present invention may take any of a wide variety of forms and configurations that offer such features and versatility as is described herein. The depicted lid support and positioner embodiment  100  is primarily formed by continuos, endless ring or annular loop of material indicated generally by the  150  which extends about in circles a central opening  175  which is best shown in  FIGS. 4 and 6 . 
         [0040]    In preferred practice, the material forming the whole of the one piece lid support and positioner  100  is selected to be a relatively resilient material having a memory that tends to return the endless ring or annular loop  150  to the configuration shown in  FIGS. 1-2, 4 and 6-8  if forced is released that has been applied to the lid support and positioner  100  to cause the continuous, endless ring annular loop of material  150  to take slightly a different form, configuration or shape such as may occur if the lid support and positioner  100  is slightly stretched to receive, or to grip opposed surfaces of a handle of a cooking vessel, as may take place when the lid support and positioner is installed on a handle of a cooking vessel as depicted in  FIGS. 9-11  hereof. 
         [0041]    The endless ring or annular loop  150  that forms a majority of the lid support and positioner  100  is defined by contiguously extending set or sequence of four nonplanar, generally c-shape portions  110 , 120 ,  130 ,  140  that (referring only to  FIG. 1 ) can perhaps be said to be separated from one another by four imaginary lines that are labeled by the letters A,B, C and D. 
         [0042]    If the imaginary lines A, B, C, and D can be thought of as designating imaginary “ends” of the C-shaped portions  110 , 120 ,  130 ,  140 , then the C-shaped top portion  110  can perhaps be said to have a first “end”  111  that joins along the imaginary line A with the first “end”  121  of the C-shaped left side portion  120 ; the C-shaped left side portion can perhaps be said to have a second “end”  122  that joins smoothly along the imaginary line B with a first “end”  131  of the C-shaped bottom portion  130 ; the C-shaped bottom portion  130  can perhaps be said to have a second “end”  132  that joins smoothly along the imaginary line D with a first end  141  of the C-shaped right side portion  140 ; and the C-shaped right side right side portion  140  can perhaps be said to have a second end region  142  that joins smoothly with a second end region  112  of the C-shaped top portion  110 . As such, the four C-shaped portions  110 ,  120 ,  130 ,  140  complete the contiguous endless ring or annular loop  150  that forms the majority of the lid support and positioner  100 . Moreover, the contiguously extending C-shape top, left side, bottom and right side portions  110 ,  120 ,  130 ,  140 , respectively, that form the endless ring or annular loop  150  cooperate to encircle the open central area or opening  175  best shown in  FIGS. 4 and 6 . 
         [0043]    As can best been seen in a side view provided by  FIG. 2  and the rear view provided by  FIG. 6 , the top and bottom C-shaped portions  110 , 130  overlie each other and extend in substantially parallel, substantially horizontally extending planes  109 , 139 . As can be seen in the front and rear views provided by  FIGS. 4 and 6 , respectively, the left and right side C-shaped portions  120 ,  140 , respectively, extend in spaced, substantially vertically extending, non-parallel planes  129 ,  149 ,—which is to say that the C-shaped side portions  120 ,  140  are more widely spaced near the front of the lid support and positioner  100  than near the rear of the lid support and positioner  100 . 
         [0044]    The top, left side, bottom, and right side C-shaped portions  110 ,  120 ,  130 ,  140 , respectively, of the endless loop or annular ring of the lid support or positioner  100  all have cross-sectional areas that are substantially equal, but the shape or configuration of the various cross-sections of the resilient material that forms the C-shaped portions  110 ,  120 ,  130 ,  140  differ somewhat along the length of the endless loop or annular ring  150 . For example, as viewed in  FIG. 3 , the C-shaped left and right side portions  120 , 140  have substantially identically sized cross-sectional areas  125 , 145 , respectively, that are of different substantially trapezoidal shape. And, as viewed in  FIG. 5 , the C-shaped bottom portion  130  has a cross-section that is substantially rectangular in shape (with slightly rounded corners), but has an area  135  that is substantially the same as that of the trapezoidal cross-sectional areas  125 ,  145  shown in  FIG. 3 . 
         [0045]    As can easily be seen in  FIGS. 1, 2, 4 and 5 , the lid support and positioner embodiment  100  has a elongate projection  160  that extends upwardly but at a forwardly inclined angle from a centrally located part  118  of the C-shaped top portion  110 . The projection  160  is of substantially uniform, generally cylindrical cross-section, and has a rounded upper end region  170 . Other possible embodiments of the present invention may have more projections, or none at all, as maybe appropriate for use with particular cooking vessels. 
         [0046]    The resilient character of the material from which the lid positioner  100  is fabricated permits various opposed parts and portions of the positioner  100  to move toward and away from each other. For example, the opposed C-shaped top and bottom portions  110 ,  120 , respectively, and the opposed left and right portions  130 ,  140 , respectively, can move short distances toward and away from each other to permit and object such as a handle of a particular cooking pan to be inserted therebetween even if the size of the handle is slightly larger than the spacings between the top and bottom portions  110 ,  130 , respectively, or between the left and right side portions  120 ,  140 , respectively. Stated in another way, the configuration of the resilient lid support and positioner  100  can be modified to enlarge or adjust the shape and size of the central opening  175 . 
         [0047]    Referring to  FIGS. 9-12 , cooking vessels  200  of identical form are shown. In  FIGS. 13-14 , differently configured but identical coking vessels  300  are shown. As will become apparent of the following discussion of what is depicted in  FIGS. 10-14 , the lid support and positioner  100  may be installed in a wide variety of ways on the handles of cooking vessels of a wide variety of types to provide support for, and to assist in the off-center positioning lids or covers of a wide variety of configurations. 
         [0048]    Each of the identical cooking vessels  200  depicted in  FIGS. 9-12  has an upstanding sidewall  210  that surrounds an upwardly opening cooking chamber  220 . The sidewalls  210  each have top surfaces or rims  230  that encircle an associated cooking chambers  220 . Elongate handles  240  connect at one end with an exterior surface of each of upstanding sidewalls  210  of the cooking vessels  200  shown in  FIGS. 9-12 . 
         [0049]    Shown in each of  FIGS. 10-12  is the lid support and positioners  100  which installed on or draped over an associated one the elongate handles  240 . In  FIGS. 10 and 11 , the depicted handle  240  extends through the center opening  160  of the depicted lid support and positioner  100 . In  FIG. 12  the lid support and positioner is draped over the associated handle  240 . In each of  FIGS. 10, 11 and 12  the lid support and positioner  100  serves to underlie, engage, support and position a portion of a off-center lid  250  that extends outside the perimeter of the associated upwardly opening cooking chamber  220 . 
         [0050]    In  FIG. 10 , the depicted upstanding projection  160  of the depicted lid support and positioner  100  can be seen to extend upwardly inside a peripheral region  270  of the associated lid or cover  250 . In  FIG. 11 , the depicted upstanding projection  160  depends downwardly in an out-of-the-way position. In  FIG. 12 , the upstanding projection  160  can be seen to extend leftwardly relative to the handle  240 , in an out-of-the-way position. 
         [0051]    Each of the identical cooking vessels  300  depicted in  FIGS. 13-14  has an upstanding sidewall  310  that surrounds an upwardly opening cooking chamber  320 . The sidewalls  310  each have tops surfaces or rims  330  that encircle an associated cooking chambers  320 . Variously configured handles  340  connect with an exterior surface of each of the upstanding sidewalls  310  of the cooking vessels  300  shown in  FIGS. 13-14 . 
         [0052]    In  FIGS. 13 and 14 , the lid support and positioner  100  is shown installed at different locations on one of the handles  340 . In FIG.  13 , the upstanding projection  160  of the lid support and positioner  100  extends upwardly inside a peripheral region of the associated lid or cover  350 . In  FIG. 14 , the projection  160  is shown extending downwardly in an out-of-the-way position. 
         [0053]    As those skilled in the art will readily understand and appreciate, a significant feature of the present invention resides in providing a simple, easy to use form of lid support and positioner that can be used with cooking vessel handles of many configurations to underlie and provide support, and possibly also to aid in positioning a an off-center lid or cover of the vessel so that the lid or cover will be better supported than if an off-center lid were attempted to be held in balance without form of over-the-handle support for portions of lids or covers that extend beyond the perimeter of the cooking chambers of cooking vessel. 
         [0054]    Although the invention has been described in a preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example, and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed. It is intended to protect whatever features of patentable novelty exist in the invention disclosed.
