DETAILED DESCRIPTION OF THE INVENTION

(12) A leveler for stabilizing furniture and other items is herein described and designed to be stacked one upon another in a stackable fashion. One or more stackable levelers may be used for many indoor, garage, patio, pool, and outdoor applications. In addition to stabilizing furniture, including tables, chairs, shelving, desks, beds, sofas, and anything with feet and/or legs, the levelers may be used in various camping and outdoor applications, including for stabilizing ladders, outdoor furniture, and kickstands. Water heaters and other appliances may also be stabilized with the levelers described herein.

(13) The levelers or stabilizing devices may be constructed of any suitable material. The leveler may be formed by injection molding with a high-friction material, which is operative to prevent slippage once it is inserted between the lower support structure of the article of furniture and the support surface. Additionally, the leveler may be 3D printed using known materials, such as with a suitable epoxy resin or a plastic resin that is similar to Acrylonitrile Butadiene Styrene (ABS) plastic. The leveler may be constructed of a relatively stiff yet flexible material and may be a plastic material selected from a group consisting of polypropylene, polyethylene, polystyrene, polycarbonate, polylactic acid (PLA), acetal, and the like. Alternatively, the leveler may be constructed of a soft gripping material such as polyethylene, polyvinylchloride (PVC), rubber, or the like. Additionally, other materials may be used to construct the levelers, including wood and metal (specifically aluminum and steel). Other materials known in the art, plastic or otherwise, are also contemplated by this invention.

(14) The leveler may be made of different materials to suit different applications and different weights. In a preferred embodiment, the levelers will be able to stabilize an object with a weight of up to 500 pounds and in a more preferred embodiment, a weight of up to 1000 pounds.

(15) For example, if indoor use is contemplated, the levelers may also include a felt layer on the 4-5 feet, similar to an adhesive felt furniture pad. The felt layer may provide a layer of protection to prevent scratching of the flooring. Further, the bottom leveler may have a felt layer, but other additionally levelers stacked thereon may not necessarily need the felt layer. Variety packs may be sold containing different shaped and sized levelers with different features.

(16) With reference to the figures, each leveler 1 comprises a horizontally disposed top surface 2 that is either square or substantially circular or any other simple stackable shape (such as, rectangular, hexagonal, and octagonal) that measures about 1.5 to about 4 inches in horizontal width or diameter.

(17) The levelers 1 have a wall 6 extending upwardly from the top surface 2 around an outer edge of the top surface 2. As depicted, the wall 6 has four notches 4 that are positioned around the top surface, preferably, at four equidistant positions around the perimeter of the top surface. Alternatively, the notches 4 may be spaced at different non-equidistant positions around the top surface. The four notches 4 are empty spaces. These may be all of the same size, or, as depicted, there may be two notches that are larger than the other two notches. The notches serve two purposes. In outdoor use, they may act to drain out water or rain. Additionally, feet of furniture may extend through the notches.

(18) The notches 4 may be positioned at the four corners of the leveler, or, as depicted, in the middle of the four sides of the wall 6 about the perimeter of the top surface 2. These may be all of the same size, various sizes, or, as depicted, there may be two notches that are larger than the other two notches.

(19) The wall 6 has a height of about 0.05 inches to about 0.75 inches measuring upwardly from the top surface 2. The leveler 1 further includes a horizontally disposed bottom surface 3, wherein the bottom surface 3 substantially corresponds to the shape and measurements of the top surface 2, meaning that if the top surface 2 is substantially circular, so is the bottom surface 3. The top 2 and bottom 3 surfaces may be other shapes, including oval, square (depicted), rectangular, hexagonal, and octagonal.

(20) The notches 4 may be placed equidistantly around any shaped leveler 1. In the case of a substantially circular leveler 1, the notches 4 may be placed at positions corresponding to 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock.

(21) There is a middle thickness between the top surface 2 and bottom surface 3. That thickness may be about 0.05 to about 1.00 inches. The stackable levelers may be of the same or of different middle thicknesses and still be stackable.

(22) The bottom surface 3 comprises four or five feet 5, wherein the four or five feet 5 have a height of about 0.05 inches to about 0.75 inches, wherein the first four feet 5 are positioned in between the four notches 4 of the top surface 2 and are offset from an outer most perimeter of the bottom surface 3 such that the feet 5 are capable of fitting within a wall 6 of a second leveler of similar height. The optional fifth foot 5 is positioned in the middle of the bottom surface 3. The feet 5 may be circular in shape (as depicted) or may be other shapes, including oval, square, rectangular, hexagonal, and octagonal. The feet 5 may be of varying sizes on the same leveler. The feet 5 may have a diameter of about 0.25 to about 1.00 inch. The optional fifth middle foot may be larger in diameter than the other four feet 5.

(23) The top surface 2 and bottom surface 3 complement each other so that a plurality of levelers may be stacked, one on top of the other, thus providing a stabilization system, as seen in FIGS. 4-11. In FIG. 4, two levelers are stacked together and shown from a side view. In FIG. 4, the top leveler's feet 5 are 0.125 inches in height, while the bottom leveler's feet are 0.062 inches in height. The height of the wall 6 of the bottom leveler and the height of the feet 5 of the top leveler are substantially the same to allow for stacking. FIG. 4 shows how two levelers of different middle thicknesses may be stacked together. The middle thickness of the top leveler is 0.125 inches and the middle thickness of the bottom leveler is 0.062 inches as shown in FIG. 4. All other dimensions of the two levelers in FIG. 4 are the same to allow for stacking and easy use.

(24) FIG. 5 shows the same two levelers of FIG. 4 in a perspective view. In FIG. 5, the levelers are stacked one on top of the other so that the similarly-sized notches 4 are aligned on top of each other.

(25) In FIG. 6, two levelers are stacked on top of each other. As also seen in FIGS. 4 and 5, in FIG. 6, the top leveler has a larger middle thickness as the bottom leveler. In FIG. 6, the smaller notches 4 of the top leveler are aligned above the smaller notches 4 of the bottom leveler. In FIG. 6, the cross sectional view is not through the center, but is offset through the walls so as to better illustrate the engagement of the top leveler on the bottom leveler.

(26) FIG. 7 is a cross sectional side view through the center of two stacked levelers with their similarly-sized notches aligned.

(27) Either position of the similarly-sized notches (aligned as in FIGS. 4-7 or opposite as in FIGS. 8-11) is contemplated by the present system of stackable levelers. FIGS. 8-11 illustrate two stacked levelers with their smaller and longer notches opposite. FIG. 8 is a side view of two stacked levelers with their similarly-sized notches opposite. FIG. 9 is a perspective view of two stacked levelers with their similarly-sized notches opposite. FIG. 10 is a cross sectional side view through the walls, offset from center, of two stacked levelers with their similarly-sized notches opposite. FIG. 11 is a cross sectional side view through the center of stacked levelers with their similarly-sized notches opposite.

(28) The stacked levelers of FIGS. 4-11 each have five feet 5. In one embodiment, a leveler may have feet the height of 0.062 inches. This leveler should be placed on the bottom of a stack. The wall height on this leveler will be the same as all other levelers. Any bottom leveler may also have felt on the bottom of its feet so as to prevent floor scratching.

(29) The figures have been drawn to scale such that the relative dimensions may be determined for the embodiment wherein the notches 4 are equidistantly spaced around the perimeter of the top surface of the leveler and for the embodiment of a leveler with five feet 5. Other embodiments and variations are possible.

(30) The foregoing description of preferred embodiments for this invention has been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings. The embodiments are chosen and described in an effort to provide the best illustrations of the principles of the invention and its practical application, and to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated.
