DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
Referring now to the drawings of the application, an educational dinnerware device 10, 10′, 10′′′is shown. The educational dinnerware device 10 has a rim 12 that is connected to both an interior surface 14 and exterior surface 16 of the educational dinnerware device 10. The educational dinnerware device 10 is shown as a bowl; however, it is within the scope of this invention for the educational dinnerware device 10 to be a cup, plate or any other suitable device for holding and consuming food. The interior surface 14 has an interior side wall 17 connected to the rim 12 and a bottom surface 18. The interior side wall 17 and bottom surface 18 are connected and integral with each other and define a food area 20 for receiving and holding food. The bottom surface 18 has an interior viewing surface 21 that is a transparent window for viewing through the interior surface 14. The interior viewing surface 21 can be a portion of the bottom surface 18 or it can be the entire bottom surface 18. Additionally, the interior viewing surface 21 can encompass both the bottom surface 18 and a portion of the interior side wall 16 depending upon the particular application.
The exterior surface 16 of the educational dinnerware device 10 has at least one exterior side wall 22 connected to the rim 12 and an exterior bottom surface 24 connected to the at least one exterior side wall 22. As shown in the drawings, the interior surface 14 and exterior surface 16 are in the shape of a circular bowl; however, it is within the scope of this invention for the interior surface 14 and exterior surface 16 to take other shapes such as squares, rectangles, triangles or any other desired shape for the educational dinnerware device 10.
The exterior bottom surface 24 has a protruding ring 26 that is used to define a card loading cavity 28 formed into the exterior bottom surface 24 of the exterior surface 16. The protruding ring 26 is used to stabilize the educational dinnerware device 10 when placed on a surface and the use of the protruding ring 26 is an optional feature of the invention. In the present embodiment of the invention, the protruding ring 26 defines the card loading cavity 28. The card loading cavity 28 has an exterior viewing surface 30 that aligns with the interior viewing surface 21 so that an object, or in the present case, a viewing card 32 placed within the card loading cavity 28 can be viewed when looking through the interior viewing surface 21.
The card loading cavity 28 has at least two wedges 34 formed within the card loading cavity 28 and extending from the exterior viewing surface 30. The viewing card 32 has two opposite viewing surfaces 36 and an edge 37 that has at least two notches 39 that are configured to press-fit onto one of the at least two wedges 34. The wedges 34 and the press-fit help to align the viewing 32 with the exterior viewing surface 30 and prevent the viewing card 32 from moving within the card loading cavity 28. At least two wedges 34 are shown; however, it is within the scope of this invention for more wedges to be used. For example, one embodiment of the invention shown in FIGS. 9 and 10 a first wedge 38, a second wedge 40 is shown. FIG. 11 shows a third wedge 42 and FIG. 12 shows an embodiment with a fourth wedge 44.
A resilient locking bar 46 shown in FIGS. 2, 4 and 6-10 extends across the card loading cavity 28 and has a first end 48 and second end 50 that are configured to press-fit into the first wedge 38 and second wedge 40 respectively. In the embodiment of the invention shown in FIG. 11 the educational dinnerware device 10′′ has a resilient locking bar 46′ with a “Y” shape and has a third end 52 that press-fits into the third wedge 42. In the embodiment shown in FIG. 12 the educational dinnerware device 10′′′ has a resilient locking bar 46′′ with an “X” shape and has a fourth end 54 that press-fits onto a fourth wedge 44. The resilient locking bars 46, 46′, 46′′ serve the purpose of holding the viewing card 32 in place within the card loading cavity 28. The resilient locking bar 46, 46′, 46′′ has two or more protrusions 56 (shown in FIG. 8) that are used to press into the surface of the viewing card 32 and hold the viewing card 32 in place.
The card loading cavity 28 has a depth “d” defined by the protruding ring 26 that allows for additional viewing cards 33 to be placed adjacent (or underneath as shown in FIGS. 5-7) the viewing card 32 and stored within the card loading cavity 28. The locking bar 46, 46′, 46′′ has a press-fit that is adjustable to accommodate and hold the additional viewing cards 33.
The locking bar 46, 46′, 46′′ further includes a handle 58 that is used to pull the locking bar 46, 46′, 46′′ from its press-fit with the respective first wedge 38, second wedge 40, third wedge 42 or fourth wedge 44. The first end 48, second end 50, third end 52 and fourth end 54 of the locking bar 46, 46′, 46′′ are bendable and resilient because the locking bar 46, 46′, 46′′ is made out of resilient plastic material. The resiliency of the locking bar 46, 46′, 46′′ allows the locking bar 46, 46′, 46′′ to move between three locking positions 60, 60′, 60′′ on each one of the first wedge 38, second wedge 40, third wedge 42 or fourth wedge 44. This is shown in FIG. 4 using the locking bar 46; however, all of the locking bars 46, 46′, 46′′ can be moved between the three locking positions 60, 60′, 60′′. Each of the wedges 38, 40, 42, 44 have two parallel nubs 62 that are trapezoidal in shape. A long side 64 of the trapezoid is formed on the exterior viewing surface 30. The two parallel nubs 62 are spaced apart from each other and inside angled side 66 that angle away from each other to create a wedge shape there between the two parallel nubs 62. The two parallel nubs 62 also have outside angled sides 68 that angle toward their respective inside angled sides 66 of each individual nub of the two parallel nubs 62. The inside angled sides 66 and outside angled side 68 provide an angled surface for the ends 48, 50, 52, 54 of the resilient locking bar 46, 46′, 46′′ to press-fit onto and define the three locking positions 60, 60′, 60′′.
In the embodiment shown in FIG. 4 the resilient locking bar 46 has only the first end 48 and the second end 50. In this embodiment, the first end 48 can hold the resilient locking bar 46 at one of the three locking positions 60, 60′, 60′′ provided that the second end 50 of the resilient locking bar 46 is placed between the two parallel nubs 62 of the second wedge 40.
The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
