  • Patent number: 6722672
    Abstract: Disclosed is a wheeled handcart having a removable debris bin, a partition, a ramp for sweeping, raking or otherwise sliding debris into the cart or its bin, and pivotable handles, wherein the cart may be utilized with or without the debris bin, and wherein the cart may be utilized in a vertical or horizontal position. To assist in preventing the debris or other content of the cart from spilling out, a partition is provided that slidably engages within tracks formed on the interior of the cart. When the debris bin is not installed, the partition serves to keep debris and other contents within the cart. Handles are pivotably connected to the cart to allow not only a multitude of advantaged lifting angles, but also the lifting of the handles such that the handles will not interfere with the loading or unloading of the cart. Alternative embodiments provide an opening in the partition for providing access to the debris bin, and an opening, rearward of the cart, useful for the spreading of granular materials.

  • Patent number: 6390495
    Abstract: A wheeled handcart having a removable debris bin and pivotable handles, wherein the cart may be utilized with or without the debris bin, and wherein the cart may be utilized in a vertical or horizontal position. More specifically, the present invention comprises a cart, a debris bin, a partition, and a ramp for sweeping, raking or otherwise sliding debris or other objects into the cart or its bin. To provide a means for removably securing the debris bin within the cart, recessed areas are formed on the exterior side walls of the debris bin which engage with protrusions formed on the interior of the cart. To assist in preventing the debris or other content of the cart from spilling out, a partition is provided that slidably engages within tracks formed on the interior of the cart. When the debris bin is not installed, the partition serves to keep debris and other contents within the cart.
