发明名称 Shopping cart safety brake system
摘要 A shopping cart safety brake system for preventing a shopping cart from rolling away from a user. The shopping cart safety brake system includes a shopping cart and a generally rectangular inverted U-shaped connector member having a spaced apart pair of elongate side rods and an upper rod connecting the side rods together. The upper rod is positioned adjacent a handle bar of the shopping cart so that the side rods downwardly depend from the upper rod. Each of the lower ends of the side rods has a pivot arm pivotally coupled to the shopping cart at a pivot point. Each of the pivot arms has a brake pad which abuts an associated adjacent rear wheel of the shopping cart when the brake pads are pivoted towards an engaged position such that each brake pad holds the associated rear wheel against rotation.
