## Background
FIELD OF THE INVENTION
The present invention relates generally to panels on top of which items can be placed, and more particularly, to panels for stabilizing bottles, cans or the like.
BACKGROUND OF THE INVENTION
The arrangement of shelves inside a cabinet structure such as a refrigerator is such that certain shelves accommodate taller item or items that must be kept upright while other shelves provide space for shorter items or items that can be laid down. Beverages such as bottles and cans can be stored inside a refrigerator by placing them on shelves provided in the compartment or shelves provided on the inside of the door. However, when these spaces are not available, the shelves may not be sufficient to accommodate these items in upright positions and simply laying down the beverage items may not be an alternative because such items are often have round surfaces and may become unstable and roll on the storage surface. Thus, there is a need to enable the usage of the height-restricted spaces at a storage area while stabilizing bottles, cans or other round items when they are laid down.

DESCRIPTION OF EXAMPLE EMBODIMENTS
Example embodiments that incorporate one or more aspects of the present invention are described and illustrated in the drawings. These illustrated examples are not intended to be a limitation on the present invention. For example, one or more aspects of the present invention can be utilized in other embodiments and even other types of devices.
FIG. 1 shows one embodiment of a stabilizing panel 10 in accordance with the present invention. The stabilizing panel 10 may be a structure that provides a substantially planar surface that can stabilize items placed thereon. The stabilizing panel 10 may be embodied as a flexible or pliable object such as a mat 10a (FIG. 1) which can be laid down on a surface but needs an underlying foundation to form the substantially planar surface and support items placed thereon. The stabilizing panel 10 may also be embodied as a firm or rigid object such as a shelf 10b (FIG. 7) that can provide a foundation and a planar surface on which to support the items. Thus, the expression ‘stabilizing panel’ should be construed broadly to encompass a mat and a shelf, but should not exclude other objects which are described as a pad, a cushion, a layer, a bed, a stratum, a tray, a receptacle, a board, a dish, a support or the like.
One example of the stabilizing panel is shown in FIG. 1 embodied as what may also be described as a mat 10a. The stabilizing panel 10 may be laid on any flat surface which may be inside an interior of an enclosed compartment that is also a temperature-controlled environment such as a refrigerator 100, a wine cellar, a freezer, or the like or in other storage areas. In this embodiment, the stabilizing panel 10 is substantially a rectangle in its entirety although other polygonal shapes are also contemplated. For example, the stabilizing panel 10 may have a parallelogram shape such as a square or be cross-shaped, L-shaped, frame-like, or otherwise. As shown in FIG. 1, the stabilizing panel 10 is configured with features that, as will be described below, enable the stabilizing panel 10 to stabilize, immobilize, firmly hold or otherwise support items with round surfaces, such as bottles or cans, so that the items do not roll or move in an undesired manner when laid down.
As shown in FIGS. 2A-2C, a first surface 12 of the stabilizing panel 10 includes a plurality of depressions 14 in which the aforementioned items can be placed and be substantially immobilized. The depressions 14 can be contrasted with a plurality of protruding peaks 16 which may be aligned longitudinally and transversely on the first surface 12 so that an orthogonal grid pattern would be formed if the peaks 16 were connected. However, other alternative arrangements of the peaks 16 are not excluded from contemplation. For example, the arrangement of the peaks 16 may form a grid in which the peaks 16 are aligned along or to be parallel with two orientations that are not perpendicular to one another. A single depression 14 may occupy a parallelogram area 18 on the first surface 12 such that the first surface 12 may be divisible into a plurality of equally sized, parallelogram areas 18 so that each parallelogram area 18 defines a single depression 14 as in FIG. 2A. Each parallelogram area 18 has four corners 20 and four edges 22, and each peak 16 is located at a corner 20 of a parallelogram area 18. It is not necessary for the entire first surface 12 to be divisible into a number of complete parallelogram areas 18. For example, the first surface 12 may be made up of complete and incomplete parallelogram areas 18.
It must be noted that, while the embodiment shown in FIG. 1 shows a square-shaped parallelogram area 18, the parallelogram area 18 may shaped as a parallelogram, a rhombus, a rectangle or the like in alternative embodiments of the stabilizing panel 10. In these embodiments with alternatively shaped parallelogram areas 18, the sides of the parallelogram areas 18, in which the opposing sides are parallel to one another, may define two orientations which the peaks 16 may be aligned to be parallel with. In other words, the arrangement of identically shaped, adjacent parallelogram areas 18 may be such that the sides become aligned.
As shown in FIG. 2B, the stabilizing panel 10 that is embodied as a mat 10a may also include a second surface 13 that is substantially flat without any protrusions. The corners 20 and the edges 22 of the first surface 12, regardless of the shape of the stabilizing panel 10, may each have a peak 16 so that, in case the stabilizing panel 10 is flipped upside down, the peaks 16 on the first surface 12 act as supporting structures so that the second surface 13 is kept flat and does not bend downward at the edges 22.
As shown in FIGS. 2B and 6, the first surface 12 may range from a first elevation 24, where the first surface 12 may be at its lowest, to a second elevation 26 that is higher than the first elevation 24 and to which the peaks 16 may rise. It is also contemplated that the first surface 12 may include one or more additional elevations that are different from the first elevation 24 and the second elevation 26 and the range of elevation may differ in one part of the first surface 12 compared to another part of the first surface 12.
In this embodiment, the midpoint of two longitudinally or transversely closest peaks 16 is at the first elevation 24, and the midpoint 17 of two closest peaks 16 is also at the first elevation 24 while the peaks 16 are at the second elevation 26 as shown in FIG. 4A. In other words, points A, B, C, D (midpoints) and E (center of depression) are at the first elevation 24 while points F, G, H, and I (peaks) are at the second elevation 26.
The geometry of the depression 14 can be explained as follows and shown in FIGS. 2B and 3. In each parallelogram area 18, one depression 14 has a constant radius of curvature R of about 1.3 inches with respect to a first axis X that is located above the first surface 12. At the same time, one depression 14 also has a constant radius of curvature R of about 1.3 inches about a second axis Y that is also located above the first surface but is perpendicular to the first axis X. This is illustrated in FIG. 3 which shows two cylinders 28, 30 whose radii have the same value R and whose axes X, Y intersect perpendicularly. As shown in FIG. 3, the first axis X may be parallel to the longitudinal edges 22a of the stabilizing panel 10 while the second axis Y may be parallel to the transverse edges 22b of the stabilizing panel 10. The resulting parallelogram area 18a near the intersection of the two cylinders 28, 30 will have a depression 14 with the same radius of curvature R about axis X and about axis Y. The depression 14 includes ridges 34 that are diagonally oriented and are formed as the peaks 16 at the second elevation 26 gradually transitions to the center 36 of the depression 14 that is at the first elevation 24. Each parallelogram area 18 of the first surface 12 may have a depression 14 with identical geometry. The same radii of curvature enable an item to be stabilized in the same manner whether the item is placed along two different orientations, which may be longitudinal and transversal for example, on the stabilizing panel 10.
However, in alternative embodiments of the stabilizing panel 10, the geometry of the first surface 12 may vary and have different or no curvatures, different elevations, or the like.
The same geometry of the first surface 12 can also be described by dividing the first surface 12 into alternatively selected parallelogram areas 19 shown in FIG. 2A. FIGS. 4B and 4C show the alternatively selected parallelogram area 19 detached from the stabilizing panel 10 and including only a single peak 16. The alternative parallelogram area 19 may include a substantially pyramidal or diamond configuration formed by four substantially triangular surfaces 21. The four triangular surfaces 21 may be concave as shown in FIG. 4B and each have a radius of curvature of R as discussed above. Thus, the peak 16 is defined by a tip of a substantially pyramid or diamond protrusion 42. The four triangular surfaces 21 meet to form the peak 16. The center 36 of depression 14 and the midpoint 17 of two closest peaks 16 are also indicated in FIG. 4C. Under the above dimensions, the distance between two closest peaks 16 are 1.38 inches.
The radius of curvature R of the depression 14 and the distance between peaks 16 are likely to be affected by the types of items 38 that are placed on the stabilizing panel 10. For example, if the contour of the item 38 is closely matched by the geometry of the depression 14, the degree of stability is likely to be higher. Moreover, as shown in FIG. 5, the dimensions of the depression 14 may also be adjusted so that two items 38, which are placed on the first surface 12 adjacent one another but separated by a depression 14, are kept apart but are sufficiently close so that an additional item 38 may be stacked above an in between the two items 38. If the round surface of the item 38 has a different radius of curvature, adjusting the radius of curvature of the depression to match this curvature may result in a more accommodating or versatile stabilizing panel 10. As mentioned above, it may be possible to have a stabilizing panel 10 in which different parts of the first surface 12 have different radii of curvature.
The resulting stability may also be affected by the material of which the stabilizing panel 10 is made. For example, the stabilizing panel 10 may be made of elastomers such as rubber that are likely to create a high coefficient of friction and improve stability for items placed on the stabilizing panel 10. However, the stabilizing panel 10 may also be made of material such as polymers which may simply offer the benefits arising from geometry but not the frictional benefits.
Although in the shown embodiment the first surface 12 transitions from the minimum elevation 24 to the maximum elevation 26 through concave surfaces, the depressions 14 in the parallelogram areas 18 may also be formed from other types of surfaces that are flat, angled, convex, stepped or otherwise. For example, the depressions 14 may be formed such that the depressions 14 have cross-sectional views shown in FIG. 6. The maximum elevation 26 need not be a point but may also be a line or a plane.
It is possible to form a stabilizing panel 10 in other types of embodiments such as a shelf 10b that is part of a cabinet structure such as a refrigerator 100. FIG. 7 shows a second embodiment in which a top surface of the shelf is configured with peaks 16 and depressions 14. The peaks 16 and depressions 14 may be molded integrally to the shelf 10b or can be formed by a separate piece that is glued to the shelf 10b. The shelf 10b may be attachable and detachable from the cabinet structure through pins 40 that are received by receptacles inside the cabinet structure. This embodiment may be mounted upside down so as to provide a second surface as well.
Referring to FIGS. 8A-8B, a third embodiment of the stabilizing panel 10c is shown. In this embodiment, the first surface 112 can be divided into a plurality of parallelogram areas 118, where a peak 116 is located at each corner 120 of the parallelogram area 118 and in which a depression 114 is formed, similarly to the first embodiment. In contrast with the first embodiment, the first surface 112 of the third embodiment includes substantially cone-shaped protrusions 142. The protrusions 142 are shaped such that an outer surface joining the tip or peak 116 and the base are concave.
Referring to FIG. 9A, a fourth embodiment of stabilizing panel 10d configured with features for securing together two or more stabilizing panels 10d (FIG. 9B) is shown. FIG. 9C shows the bottom of the stabilizing panel 10d on which male connecting sections 150 and female connecting sections 154 are formed with discontinuous sections 158. The stabilizing panel 10d may be described as having a two-layer periphery wherein a bottom layer 168 is offset about a top layer 170 in a diagonal or angled direction such that the edges of the bottom layer 168 become offset from the neighboring edges of the top layer 170.
The two-layer structure forms, on the stabilizing panel 10d, a male connecting section 150 extending substantially along each of a pair of adjacent first edges 152 and with a female connecting section 154 extending substantially along each of a pair of adjacent second edges 156. In this embodiment, the male connecting section 150 projects outwardly from each first edge 152 so as to form an L-shape while the female connecting section 154 is formed on the second surface 13 in an L-shape configuration. The second surface 13 may be flat or engraved as shown in FIG. 9C.
As shown in FIG. 9D, the boundary of two neighboring stabilizing panels 10d is shown. A male connecting element 160 is formed on the male connecting section 150 while a female connecting element 162 is formed on the female connecting section 154. The male connecting element 160 and the female connecting element 162 may each include a tongue portion 164 that is vertically oriented and a groove portion 166 in which the tongue portion 164 of the other connecting element can be accommodated. The male connecting element 160 and the female connecting element 162 are shaped such that neighboring stabilizing panels 10d can interlock along the edges as shown in FIG. 9D.
The male connecting section 150 may be identical in length to the corresponding first edge 152 except that the male connecting section 150 is offset. As a result, the male connecting section 150 does not extend fully along the first edge 152 and the first edge 152 may include a discontinuous section 158. As shown in FIG. 9B, the discontinuous section 158 allows the stabilizing panels 10d to be placed next to one another without the male connecting section 150 of one stabilizing panel 10d overlying the male connecting section 150 of another stabilizing panel.
The invention has been described with reference to the example embodiments described above. Modifications and alterations will occur to others upon a reading and understanding of this specification. Example embodiments incorporating one or more aspects of the invention are intended to include all such modifications and alterations insofar as they come within the scope of the appended claims.
