  • Patent number: 8544407
    Abstract: An attachment module for a safety cone permitting a variety of safety enhancing devices to be easily attached to the cone. The attachment module comprising a top ring and a bottom ring joined together to form an assembly. The top ring and bottom ring sized to conform to a predefined safety cone angle or range of angles, the assembly having an attachment arm for attaching a safety-enhancing device. Examples of safety enhancing devices include, but are not limited to a flag, a sign, a safety tape holder, a light, or other safety-enhancing device. The assembly may be placed over a safety cone and is held secure by gravity and the wedge of the cone angle. Safety enhancing devices may then be attached to the module and thus to the cone to improve the effectiveness of the cone.

  • Patent number: 7730666
    Abstract: A double walled plant container wherein the two walls or shells form a space for holding water. The outer wall may include a window for viewing water level. The container includes a combination watering funnel and handle arrangement at the top of the container. The watering funnel protrudes or extends from the outer perimeter of the characteristic shape of the container to allow grip of the container for carrying. Preferably two watering funnel and handle structures are included, one each on opposite sides of the container. The rim arrangement allows for convenient carrying without separating the container components. The bottom of the inner shell includes holes for conducting water from the water reservoir into the soil and may include a fiber wick and soil stop barrier to prevent entry of soil into the space between the two walls and to allow water to conduct by capillary action or otherwise into the soil.
