发明名称 Debris collection systems, devices and methods for attachment to chairs
摘要 A debris collection system includes a collection device configured to be coupled to legs of a chair. The collection device has an open top end and a bottom end and a plurality segments coupled to one another. Each segment includes a fastening mechanism, wherein the fastening mechanisms of adjacent segments are coupled to one another such that one of the legs of the chair extends between the fastening mechanisms of the adjacent segments. Optionally, the collection device may have a frusto-conical shape. The bottom end may be open and debris collected by the collection device may be channeled by the collection device through the open bottom end. Optionally, a container may be positioned below the open bottom end to collect debris directed through the open bottom end. The collection device may have a funnel shape with walls that taper inward from the top end to the bottom end. Each of the segments may be substantially identically formed to define the collection device.
