Abstract: A connector for pivotably connecting two structural members together includes a generally planar member having a plurality of semi-circular tabs extending from the planar member. The tabs are semi-circular to pivotably receive a vertically extending rod member of one of the structural elements. The connector may include a semi-cylindrical wall portion that is adapted to receive and capture a horizontally extending rod member of one of the structural members.

Abstract: A handheld article carrier is designed to accommodate dumbbells and other personal items such as water bottles, cellphone, keys etc. The carrier may be formed from a single piece of sheet metal material and is generally U-shaped. The carrier includes sidewalls each having a slot for supporting the shaft portion of one or more dumbbells. The carrier includes a handle that may be integrally formed in a central portion of the frame of the carrier, or attached as a separate piece. The article carrier can be made from a single sheet of metal, multiple sheets of metal, a combination of metal and natural materials, all natural materials, a combination of metal and synthetic materials, or all synthetic materials.

Abstract: A method for using a filtration system is provided. The filtration system can include a container, an inner cup, and a filter pad. The filtration system can be configured to remove undesirable impurities from liquid. For example, the filtration system can be configured to remove total polar molecules and lovibond color red from used cooking oil.
