Abstract:
A unitary stackable vertical panel channelizing device having a body, a lower portion and an upper portion, the body comprising: first and second generally rectangular flat panels, each flat panel having two opposing elongated edges of a first predetermined length and upper and lower edges of a second predetermined length that is shorter than the first length, each flat panel having an outwardly facing rectangular recessed area formed therein for receiving retroreflective sheeting thereon;first and second end panels, each end panel having a lower edge of a third predetermined length and two side edges of a fourth predetermined length, which side edges extend generally vertically up toward the upper portion of the channelizing device; andfour curved corners, each curved corner connecting a side edge of one end panel to a side edge of one of the flat panels, each curved corner having a predetermined radius proximate the upper portion of the channelizing device that gradually tapers into a second, larger predetermined radius proximate the lower portion of the channelizing device, the curved corners thereby mounting the flat panels in back-to-back relation to each other and separating the flat panels from each other by a predetermined angle;the lower portion comprising: a generally rectangular bottom section having first and second elongated sides and first and second shorter sides, the bottom section including a road surface engaging portion with rounded outer corners and a flat bottom surface adapted to rest on a road surface; a transition section formed around the circumference of the road surface engaging portion and extending upwardly in a curved wall around the circumference of the bottom section to connect with the body, the lower shorter edge of the first flat panel being connected to a part of the transition section formed on the first elongated side of the bottom section and the lower shorter edge of the second flat panel being connected to a part of the transition section formed on the second elongated side of the bottom section; and the upper portion comprising: a handle; a curved top; and a wall for sealing the top of the channelizing device;the handle being of a predetermined length and the predetermined angle being such that, when stacked, the channelizing devices do not jam together but are easily unstacked.
