  • Patent number: 10889946
    Abstract: A system and method for removing rolls of synthetic turf by connecting a strip of synthetic turf to one or more winches powered by batteries or solar cells, the synthetic turf connected to the winches by a series of winch cables and a pull bar having one or more synthetic turf clamps, whereby once connected, the winches retract the winch cables thereby inverting the synthetic turf and moving the pull bar and synthetic turf across a connected comb. The comb has wheels, a frame, and agitating members such that when the synthetic turf is pulled over the comb, the comb causes vibrations in the synthetic turf so that the infill is displaced from the synthetic turf where the infill may then be collected in a receptacle below for transportation and recycling.

  • Publication number: 20200087035
    Abstract: A chair bag includes a tapered portion that extends along a substantial side portion of the bag from its lower portion to its upper portion. The tapered portion increases in diameter from its lower portion to its upper portion, until reaching a joint located near the upper portion of the bag. At the joint, the diameter or circumference of the bag is preferably substantially the same as the diameter or circumference at a mouth portion of the bag. Snap fasteners are preferably provided from the joint to the top portion of the bag where the mouth portion is located. When the snap fasteners are disengaged from one another, the mouth portion has a diameter or circumference greater than when the snap fasteners are engaged with one another. This structure may improve the difficulty involved with the process of placing a chair into or removing a chair from the bag.
