Abstract:
1. Cart to facilitate collection, storage and distribution of folding warning lines, with the folding warning lines including rigid members and a flaccid member, with the cart comprising, in combination: a framework having a first side and a second side, with each of the first side and the second side terminating in a top, a bottom, a front, and a back, with a storage area for the folding warning lines located between the first side and the second side, with the storage area being accessible between the fronts of the first side and the second side, with the framework having a top member extending laterally between the tops of the first side and the second side, with the framework having a bottom member extending laterally between the bottoms of the first and second sides, with the bottom member defining a plurality of slots, with the top member defining a plurality of notches, with the plurality of slots and the plurality of notches adapted and cooperating to receive and retain the rigid members of the folding warning lines to facilitate orderly storage of the rigid members of the folding warning line; a holder on the framework, with the holder being adapted to receive, store and release the flaccid member of the folding warning lines without tangling; an engagement device on the framework to accommodate engagement by a crane to transport the framework and the folding warning lines stored thereon to a work surface; a rolling support rotatably mounted to the framework, with the rolling support providing mobility on the work surface; a handlebar on the framework, with the handlebar enabling the framework to be tilted rotationally about the rolling support and pushed in a movement direction, with the fronts of the first side and the second side located ahead of the backs of the first side and the second side in the movement direction; a stabilizer, with the stabilizer engaging the work surface when the framework is in an immobile position, with the stabilizer cooperating with the rolling support to support the framework in the immobile position, wherein when the framework is in the immobile position the first side and the second side of the framework are inclined toward the backs at a retention angle, wherein when the first and second sides are at the retention angle, the rigid members of the folding warning lines are gravitationally retained in the storage area, with the plurality of slots adapted to constrain lower ends of the rigid members in frontward, backward, sideward and downward directions, with the frontward direction being towards the fronts from the backs of the first and second sides, with the backward direction being toward the backs from the fronts of the first and second sides, with the sideward direction being toward the first side from the second side or toward the second side from the first side, with the downward direction being toward the bottom member from the top member of the framework, with the phirality of notches adapted to constrain upper ends of the rigid members in the backward and sideward directions, with the retention angle gravitationally constraining the upper ends of the rigid members from movement in the frontward direction when the framework is in the immobile position; and a retainer adjustable between a retaining position and an open position, with the retainer constraining the rigid members of the folding warning lines from movement in the frontward direction when the retainer is in the retaining position, with the retainer in the open position leaving the upper ends of the rigid members unrestrained in the frontward direction to facilitate loading and unloading of the folding warning lines.
