DETAILED DESCRIPTION OF THE DISCLOSURE
The construction kit 1 includes a plurality of construction rods 2. The construction rods are elongated rounded sticks, having disks 5 positioned along the length of the construction piece. Each disk 5 is comprised of two identically shaped conically shaped half disks 6,7, each half disk sharing a common rim 8. Each half disk 6,7, has a base 16, with the base 16 being smaller than the rim 8. Depending on one's perspective, the base either tapers upwards towards the rim 8, or tapers away from the rim 8. There is also a side 17 surrounding and between the circumference 18 of the rim and a circumference 19 of the base. Between the disks are curvatures 25. The construction rods are comprised of either plastic or rubber. The disks 5 are part of an integrally molded with the rod 2.
All of the disks 5 on a single construction rod 2 are of the same diameter and size, with the disks to the rod ratio ranging from about: 3.5:1 to about 4.5:1. In another embodiment, the ratio is 4:1. The distance between the disks ranges from 10-14 mm.
Each end of the rods 2 terminates in a half disk 6,7, with the rim 8 of each of the half ridge 6,7 facing outward. In one embodiment, the outside ends 20, 21 of each of the half ridges 2 are rounded or slightly curved. The rods 2 are made by means of an extrusion molding process known in the industry. In one embodiment of the disclosure, there are molding holes 15 periodically in the rounded stick 9.
In one embodiment, the kit comprises construction pieces of different lengths based on the number of disks 5 present. The smallest construction piece 12 has merely two half disks 6,7 the bases 8 of which face inward. Between every two disks or half disks is a groove 25. The length of the smallest piece can range from about 14.-14.4 mm. In one embodiment, the length is 14.28 mm. The larger of the construction piece 13 can have 10-15 or more disks 5.
More specifically, the number of and different lengths of the rods in the kit varies. For example, in one kit, there can be:

    
    
        0>30 one groove rods
        0>30 two groove roads
        0>30 three groove rods
        0>30 four groove rods
        0>30 five groove rods
        0>30 six groove rods
        0>30 seven groove rods
        0>30 eight groove rods
        0>30 nine groove rods
        0→30 ten groove rods
        0>30 eleven groove rods
        Etc.
    
    


In another embodiment, the different length construction rods 2 are of different colors. Colors that are used include but are not limited to yellow, orange purple, blue, red, and green. Alternatively, the rods can be translucent with color, or they can be completely transparent with a tint of color, or no color.
In one embodiment, the construction rods interlock. This is accomplished by the proper sizing and positioning of the various parts of the construction rod. In one embodiment, the angle of the curvature 200 of the groove between disks is 107 degrees. The radius of the curvature 201 is 4.00 mm. The curvature of the peak 202 of the disk is 0.30 mm, and the curvature of the end section 203 of the construction rod has a radius of 15.6 mm. Measuring along the Y axis, the width of the construction rod from the top of one rim 204 on a disk 206 to the opposite peak 205 on an opposite disk 207 is 12.2 mm. Measuring along the Y axis, the width from the bottom of one curvature 208 to the bottom of another curvature 209 is 6.10 mm. Of course, the construction kit can have pieces that are larger or smaller than that which is indicated in the figures, supra. Even if the pieces are several times larger than the figures given above, the ratio(s) of the various measurements remain(s) the same.
As shown in FIG. 10, the best method of “connecting” or “locking” the construction rods together is to have the pieces connected along the x, y, and z axis. As shown in the figure, a construction rod 400 in the z position is bound by two construction rods 401, 402 in the x position, and construction rods 400, 401, and 402 are bound by construction rods 403, 404, 405, 406 in the y position. An exploded view of this assembly is shown in FIG. 11. The interconnection of the various parts puts pressure on each of the parts, and in particular on the disks, which in turn secures the various construction pieces in place.
In another one version or example of the construction kit, the construction rod 1 is flexible. When the rod is flexible, the construction rod 1 is made of a flexible wire 3 encased in plastic 4. More specifically, the center of the length of the construction rod 2 is a flexible wire 3. In one embodiment, the wire 3 is made out of stainless steel. In another embodiment, the wire 3 is made out of copper. In other embodiments the wire is made out of chrome, steel, aluminum, alloys, or other metal wires. In one embodiment, the metal wire resists oxidation. The wire 3 is from about 1.0 mm to about 2.5 mm thick. In another embodiment, the wire is from about 1.0 to 2.0 mm thick, and in another embodiment, the wire is 1.5 mm thick The wire 3 runs from about half to the full length of the rod 2. In relation to the widget of the wire, the rod is from about 20 to 30 mm thick. In another embodiment, the rod is from about 25 to 30 mm thick, and in another embodiment, the rod is 28 mm thick. Fundamentally, the rod width to wire thickness is about 18:1 to 20:1. Note that the width and length of the rod can vary, and as such, the dimensions of the wire will vary in the ratios given. In an alternative embodiment, a “large” version of this toy construction kit has the same ratios, only with much larger dimensions.
The plastic 4 itself is a durable plastic that accepts any plastic extrusion colorant prior to the extrusion process. In one embodiment, the plastic 4 is ethylene-vinyl acetate. In another embodiment, the plastic 4 is high impact polystyrene, and in yet another embodiment the plastic is acrylonitrile butadiene styrene. The plastic 4 is any durable plastic that can be bent without tearing or breaking. The wire 3 encased in the plastic allows the plastic to be bent without memory issues. In another embodiment of the disclosure, the construction rods are also magnetic. In the non-bendable rods, a magnetic rod is molded within the plastic rod, being molded by means of an extrusion process. The magnet can be made out of any of the magnetic elements, alloys, and minerals, including ferromagnetic materials such as iron, nickel, cobal talloys of rare earth metals, and some naturally occurring minerals such as lodestone. Other materials that can be used include: Alni, Alcomax, Hycomax, Columax, and Ticonal, as well as samarium-cobalt and neodymium-iron-boron (NIB) magnets.
In another embodiment, the bendable construction rods also contain a magnetic wire or force encased within the plastic. In one embodiment, the magnetic wire is thicker than a non-magnetic version of the construction rod, while still being bendable. In another embodiment, small magnetic elements are embedded within the plastic during the extrusion process. In yet another embodiment, the wire running through the plastic is made of a very powerful magnetic material.
In another embodiment, the construction rods 2 are not bendable. In one embodiment, these construction rods still have the property to be “interlockable” with other construction rods. In another embodiment, these construction rods are magnetic. In another embodiment, the non-bendable construction rods 2 have all of the features of the bendable rods, except that they are not bendable.
In an alternative embodiment, the rods can be held together a series of small pegs 500 and holes 501 that are used to secure each of the construction rods together. Both the pegs 500 and the holes 501 are positioned in the curvatures between the disks. One side of the rods contain the pegs 500 while the holes 501 are positioned either 90 degrees and/or 180 degrees rotation on the rod. In one embodiment, there are one row of holes 501 on one side of the construction rods 2 and 180 degrees on the other side are the pegs 500. Alternatively, there can be alternating rows of pegs 500 and holes 501. The pegs 500 are integral with the plastic or rubber of the construction rod. In one embodiment, the holes 501 and pegs 500 are used instead of magnets or other forms of attachments.
In yet another embodiment, the holes and pegs are used with other embodiments.
In one embodiment, the kit also includes tires 30. The tires can be of any size. In one embodiment, there are a set of these tires 30 can range in size from 1′′ in diameter to 4′′ or more in diameter. In another embodiment, the tires are from about 3⁄4′′ to 3′′ or more. In yet another embodiment, the tires are from about 1′′ to about 2′′ in diameter. The tires 30 are made out of a material that is selected from the group consisting of rubber, foamed rubber, and flexible plastics. In one embodiment, the tires are made out of ethylene vinyl acetate. In another embodiment, the tires are made of cardboard. The tires have a small hole 33 in the middle of the flat surface of the tire 30, from about 1⁄4′′ to about 3⁄8′′ in diameter. This hole 33 stretches to fit over the first disk (or half disk) at each end of the rod 2.
In yet another embodiment, the construction kit includes hooves 100, 101 and heads 102, 103 of animals. These parts allow children to make animals or dinosaur type structures with the construction kit.
The kit also comes with a mat 40. In one embodiment, the plastic is comprised of a rigid plastic, semi-rigid plastic, rubber, metal, or wood. In another embodiment, the plastic is ABS plastic. The mat can be a variety of shapes. In one embodiment, the mat 40 is rectangularly shaped. In another embodiment, the mat is square, rounded, oval, a hexagon, a pentagon, a septagon, an octagon, or any other geometric shape. In another embodiment, the mat is amorphous shaped. The surface 41 of the mat 40 is waffled. More particularly, the surface 41 comprises a plurality of rectangular wells 42 formed by a plurality of intersecting walls 42,43. The wells 42 are large enough and spaced such that the disks 5 of the rods 2 mate with a row 44 of wells 42.
In one embodiment, the surface 41 of the mat 40 has four sides 45, 46, 47, and 48. On the underside of each corner of the surface 41 are legs 49, 50, 51, and 52, which in one embodiment have rubber tips 53, 54, 55, and 56.
Referring to FIGS. 6a-6d, it is easy to intermix the different sized rods or construction pieces together. FIGS. 7a-7e show the construction of a “log cabin,” using the intersection of different sized rods.
In another embodiment, the tire is fitted over and into a groove (FIG. 8).
In another embodiment of the disclosure the design of the disclosure, the kit has a snap and lock feature which locks and holds the pieces in a fixed position allowing a user to lift and play with the item that was constructed. The FIGS. 9a-9f show the steps of the construction for a race car using the snap and lock feature.
Specifically, the first step is to position two eleven groove rods 60, 61 parallel to each other. At each end 62, 63 a three groove rod 64, 65 is laid cross sectionally on top of and across the two eleven groove roads. At each end another three groove rod 66, 67 is positioned perpendicularly on the inside of the rods 64, 65. At each end, seven piece groove piece 68, 69 is positioned equilaterally in front of the perpendicular three groove rod 66, 67. At one end 62, another three groove rod 71 is positioned perpendicularly to said groove rod 69 and parallel to said three groove rod. That in turn is secured in place by a three grooved part 72 in front of and parallel and in contact with seven piece groove piece 69. Next, parallel eleven groove rods 72, 73 are placed on top of an in parallel with rods 60, 61.
The rest of the drawings show the progression of how the pieces are secured together.
