  • Patent number: 11565447
    Abstract: Apparatuses, methods, and systems are disclosed for a spacer for a manufactured structure. A spacer includes a plurality of legs where each leg includes an elongate member that extends from a proximal end to a distal end. The proximal end of each leg is connected to one another at a central point such that the legs are spaced radially about the central point and substantially equidistant from one another. The distal ends of the legs include a material that has a predefined melting point such that the distal ends attach to a surface in contact with the distal ends responsive to the predefined melting point being reached during a molding process.

  • Publication number: 20220185104
    Abstract: An over the wheel well tank for storing liquid in a bed of a truck includes a tank body having a main tank portion shaped to fit in an area adjacent a wheel well in the bed of a truck and an over a wheel well tank portion shaped to fit in an area above a wheel well in the bed of a truck. The main tank portion is shaped to fit in an area adjacent a proximal side of the wheel well or in an area adjacent a distal side of the wheel well. The storage tank may further include a pumping system to pump liquid from within the storage tank to a location external to the storage tank.

  • Patent number: 7635114
    Abstract: A decorative post includes an elongated outer polymer shell having at least one longitudinal groove extending a majority of a length of the elongated shell sized and shaped to hold a decorative fence panel. The decorative fence post also includes an elongated reinforcing member disposed in the outer polymer shell, and substantially extending a length of the fence post. A foam filler is disposed inside the outer polymer shell between the shell and the reinforcement member. An aperture is disposed in the outer polymer shell near an end of the reinforcing member, and a void extends from the aperture into the foam filler adjacent to and exposing an end of the reinforcing member. The void defines a slip zone at the end of the reinforcing member into which the reinforcing member extends as the outer shell shrinks longitudinally during post mold cooling.

  • Patent number: 7478797
    Abstract: The opposite plastic walls 20a and 20b can be made from a polymeric resin material such as thermoplastic or thermoset resin, and/or can be made from olefins, styrenes, nylons, or mixtures of these polymeric families. In one aspect, the opposite plastic walls can be formed from an olefin, such as polyethylene or polypropylene, or the like. In another aspect, the opposite plastic walls can be formed from a styrene, such as acrylonitrile or butadiene styrene, or the like. In still another aspect, the opposite plastic walls can be formed from a mixture of olefins and styrenes. The polymeric resin material can also be made from recycled olefin, styrene, or nylon products. It will also be appreciated that the material of the walls can include additives, such as glass, fiber, talc, UV resistive or protective materials, etc. In one aspect, plastic granules of different colors can be combined to obtain a wall color that is a composite color to more readily simulate another material.

  • Patent number: 7273571
    Abstract: A plastic table structure includes a tabletop comprising a thin polymer shell layer surrounding an expanded foam core. The multiple layers of the finished tabletop are molded concurrently in a one-pass biaxial or centrifugal rotational molding process, and cured in an oven. The method includes the steps of introducing polymeric material into a mold, and rotating the mold while heating it to a first temperature so as to form a molten shell of a portion of the polymeric material on the inside of the mold. A foaming agent is introduced within the mold and mixes with a second unmelted portion of the polymeric material and distributes throughout the mold. When the mold reaches a second higher decomposition temperature, the foaming agent causes expansion of the second portion of the polymeric material, forming an expanded foam core inside the shell.
