Thus, for example, any aspect may be combined with an aforementioned feature in accordance with the present invention without requiring any other aspect or feature.
One or more preferred embodiments of the present invention now will be described in detail with reference to the accompanying drawings, wherein the same elements are referred to with the same reference numerals.
As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.
Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purpose of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.
Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein.

With respect to the United States, and regarding applicability of 35 U.S.C. §112(f), no claim element is intended to be read in accordance with this statutory provision unless the explicit phrase “means for” or “step for” is actually used in such claim element, whereupon this statutory provision is intended to apply in the interpretation of such claim element.
Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”
When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without cheese”, and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”
Referring now to the drawings, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its implementations, or uses.
An embodiment 100 of a pancake maker apparatus in accordance with one or more aspects and features of the present invention is schematically illustrated in perspective view in
The mix hopper 104 is maintained in the elevated position by vertical wall supports 127 that extend upwardly from a base plate 118. A horizontal frame member 128 spans the vertical walls 127. A top shelf 129 also spans the vertical walls 127. A gearbox and motor assembly 102 supported by the top shelf 129 drives a cam that engages a rod inside the mix hopper 104. Moreover, while shown in the drawings as being located adjacent a side of the griddle 125, the gearbox and motor assembly 102 may be located under the griddle 125 to provide a more compact arrangement. The gearbox and motor assembly 102 is actuated by a controller 103 that is configured to cause a predetermined amount of pancake batter to be dispensed at a predetermined time or predetermined time interval downwardly in the direction of arrow A onto a griddle 125.
The griddle 125 also is secured to and is supported on the base plate 118 by L-shaped brackets. The griddle 125 is configured to pivot about axis P1 of hinge pins 212 (shown in
The embodiment 100 further includes a second griddle 123 similar in size and shape to the first griddle 125 that also is secured to and is supported on the base plate 118 by L-shaped brackets. The second griddle 123 is configured to pivot about axis P2 of hinge pins from an originally horizontal orientation to an obtuse angle. Rotation of griddle 123 is driven by gearbox and motor assembly 113 similar to that of gearbox and motor assembly 107 and linkage arm assembly 112, and an intermediate position of the griddle 123 during rotation is represented by griddle 123 shown in dashed lines in
In some contemplated embodiments, the griddle 123 is rotated to an inverted position (rotated greater than 90 degrees) such that the griddle 123 at least partially extends beyond an edge of the base plate 118 vertically over a serving plate that may be positioned to receive a cooked pancake. Indeed, the griddle 123 may be rotated beyond 90 degrees to nearly 180 degrees, causing the second griddle to project substantially from the remainder of the cooking apparatus. Preferably, however, the griddle 123 rotates to no more than around 90 degrees and remains within a body of the cooking apparatus for a more compact arrangement.
As shown, a first axis P1 extends in a direction that is generally orthogonal to the direction in which a second axis P2 extends, although in contemplated alternatives, the griddles are arranged in-line with the first and second axes extending in parallel. Furthermore, as shown, griddle 125 is supported above the base plate 118 at a greater distance, i.e., higher elevation, than that of griddle 123. Griddle 125 also is oriented such that, when rotated into a fully extended position, griddle 125 extends over griddle 123.
A heating plate is provided under each griddle for heating the cooking surface of the griddle. Preferably, each heating plate is not secured to its respective griddle and does not rotate with the griddle. Heating plate 122 is positioned under griddle 123, and heating plate 124 is positioned under griddle 125. In alternative embodiments, the heating element is secured to the griddle and rotates with the griddle.
Preferably, a wiper is provided with each griddle. In this respect, wiper 105 is provided with griddle 125 and wiper 111 is provided with griddle 123. Each wiper is configured to sweep the surface of its respective griddle. As shown, in the embodiment 100, each wiper is attached to its respective griddle at one of the four corners of each griddle and further is configured to rotate thereabout when sweeping the griddle surface. Sweeping movement of each wiper is driven by engagement of an arm of the wiper that engages a rail during rotational movement of its respective griddle. Wiper 105 rotates about axis P3 of a hinge pin (illustrated in
During its rotational movement, arm 114 of wiper 105 engages rail 133—and specifically at a point during a downward arc of its rotational movement, causing arm 114 to rotate about an axis and wiper 105 to sweep the cooking surface of the griddle 125 while the griddle 125 continues to rotate thereafter. The point of engagement of the arm 114 with the rail 133 is preferably at an angle of about 100 degrees of the cooking surface of the griddle 125 relative to the cooking surface of the griddle 125 when starting at the horizontal position.
In similar manner, arm 115 of wiper 111 engages rail 135 during its rotational movement—and specifically at a point during an upward arc of its rotational movement, causing arm 115 to rotate about an axis and wiper 111 to sweep the cooking surface of the griddle 123 while the griddle 123 continues to rotate thereafter.
As further disclosed below, each wiper is spring-biased to a standby position at which a length thereof extends adjacent to a side of the griddle, and only undergoes rotational, sweeping movement when its arm engages a side rail during rotational movement of the griddle to which it is attached.
Accordingly, it will be appreciated that the wiper 105 is shown in an intermediate position during its rotational movement across the griddle cooking surface for illustration purposes only, and that at the particular position of the griddle 125 shown in
The griddles 123,125 and wipers 105,111 illustrated in

With reference to
Preferably, the embodiment 100 also includes a control system with controls for the different aspects of the apparatus required for cooking. The controls preferably are located on an exterior of the apparatus for access and operation by the user. The control system may be automated on single-use settings, and may allow a user to adjust pancake size, the number of pancakes cooked, and a time at which to begin cooking, similar to automated coffee makers. Furthermore, in contemplated embodiments, automated mixing of pancake batter in the hopper assembly is provided. As currently contemplated, the controls preferably will be used to set temperature (heat of the griddles), size of the pancake, and the number of pancakes to be made. In addition, it is contemplated that a warming light may be used to indicate when the griddles are hot and another light to indicate when the hopper requires refilling.
Alternative means for dispensing batter other than a hopper also are contemplated and include use of a peristaltic pump; use of a screw pump (Archimedes screw); use of a compressed bag and roller system; and use of disposable capsules or cups, each containing a predetermined volume of pancake mix.

Additional embodiments similar to that of FIGS. 12-17 are disclosed respectively in FIGS. 29-34 of the Application Publication, in FIGS. 35-38 of the Application Publication, and in FIGS. 39-43 of the Application Publication.
In particular, FIG. 29 of the Application Publication is a schematic perspective view of another embodiment of a pancake maker apparatus 2900 in accordance with one or more aspects and features of the present invention. FIG. 30 of the Application Publication is a schematic plan view of controls for the embodiment of FIG. 29 of the Application Publication, and FIGS. 31-34 of the Application Publication are additional schematic perspective views thereof.
FIG. 35 of the Application Publication is a perspective view of the front of a rendering of a commercial pancake maker 3500 similar to the embodiment of FIG. 29 of the Application Publication; FIGS. 36-37 of the Application Publication are perspective views of the front of the pancake maker 3500; and FIG. 38 of the Application Publication is a perspective view of the back of the pancake maker 2900.
As shown in these drawings, each of the apparatus 2900,3500 is not automated and includes manual operation of one or more lifting mechanisms and, preferably, operation of a lifting mechanism and associated wiper by manually operating a corresponding lever. Additionally, each further comprises a manual control knob that is rotatable for actuating the dispensing of food onto the cooking surface.
Each apparatus further includes a hopper and a housing cover comprising a support within which the hopper is received and supported in disposition over the cooking surface of the first griddle. The hopper is removably received within and rests upon the support. The housing cover is hingedly attached to a housing of the apparatus for pivotal movement between a closed position, in which the housing cover generally encloses the cooking surfaces, and an open position, in which the cooking surfaces are generally accessible for manual cleaning. Alternatively, the housing cover may be removably attached to the housing for accomplishing the same purpose. In both scenarios, the housing cover preferably is transparent for viewing of items being cooked on the cooking surfaces.
FIG. 39 of the Application Publication is a schematic perspective view of another embodiment of a pancake maker apparatus 3900 in accordance with one or more aspects and features of the present invention. Furthermore, each of FIGS. 40-43 of the Application Publication is a schematic perspective view of components of the pancake maker apparatus 3900. As shown therein, the pancake maker apparatus 3900 includes channels 3996,3998 formed in respective walls of housing 3986 which channels engage ends of the wipers during lifting of the griddles. It will further be appreciated that for illustration purposes two different positions of a wiper of each griddle are shown in FIGS. 40-42 of the Application Publication. Furthermore, FIGS. 41-43 of the Application Publication illustrate the lifting mechanisms, each comprising a respective gearbox and linkage assembly 3936,3938 actuated by a lever. Representative gears 3942,3940 themselves are illustrated in FIG. 42 of the Application Publication. FIGS. 42-43 of the Application Publication further serve to illustrate and represent embodiments in which a heating element 3933 and thermostat 3935 of a griddle 3932 are connected to and move with the griddle during lifting.
