Traffic flow barrier with corresponding production mold and hand cart
A barrier system is used to direct and block a travel path of pedestrians and vehicles. The barriers may be shaped substantially as a truncated pyramid with a base surface and planar sides extending from the edges of the base surface to a top portion, where the cross-sectional area of the base surface is larger than the cross-sectional area of the top portion. The angles of inclination between the planar sides and the interior of the base surface are acute angles. The bollard can be cast from heavy dense materials. The bollard includes at least two overhanging lips on the planar sides of the barrier between the base surface and the top portion. The configurations of the bollards provide improved placement, such as with cranes, hand carts, and other devices. Molds to cast the barriers and hand carts to move the barriers are also disclosed.
1. A barrier to vehicular passage comprising:
a rectangular base formed as a bottom support surface of the barrier, the rectangular base including a length, a thickness, and a width;
a rectangular curb formed above the base and in cooperation with the rectangular base, the rectangular curb including a length, a thickness, and a width, wherein the length and width of the rectangular curb extends beyond the length and width of the rectangular base to form one or more overhanging lips to provide lifting points to move the barrier;
four planar sides each in cooperation with the rectangular curb and extending vertically from the rectangular curb to a top portion at substantially the same angle of inclination, wherein the combination of the rectangular curb, the four planar sides, and the top portion form a truncated pyramid above the rectangular base and in cooperation with the rectangular base.
2. The barrier to vehicular passage of claim 1 , wherein the rectangular base, the rectangular curb, and the top portion are substantially parallel.
3. The barrier to vehicular passage of claim 1 , wherein the top portion includes a length, and the length of the rectangular curb is greater than the length of the top portion.
4. The barrier to vehicular passage of claim 1 , wherein each of the four planar sides has a length and a width, and wherein the four planar sides are two pairs of opposing planar sides, and wherein each of the opposing planar sides has substantially the same respective length and the same respective width.
5. The barrier to vehicular passage of claim 1 , wherein each of the four planar sides has a length and a width, and wherein the four planar sides are two pairs of opposing planar sides, and wherein each of the opposing planar sides of the pair of planar sides has substantially the same respective length and the same respective width.
6. The barrier to vehicular passage of claim 1 further comprising:
an attachment point embedded in the top portion of the barrier, wherein the attachment point is at least one of a hook and loop.
7. The barrier to vehicular passage of claim 1 , wherein the barrier is made of a pre-cast material, and wherein the precast material is at least one of cement and concrete.
8. The barrier to vehicle passage of claim 1 , wherein the width of the rectangular curb extends beyond the width of the rectangular base in both lateral directions to form the one or more overhanging lips.
9. The barrier to vehicular passage of claim 1 , wherein the length and the width of the rectangular base are substantially the same and the length and width of the rectangular curb are substantially the same.
10. The barrier to vehicular passage of claim 9 , wherein the top portion includes a length and a width, and the length and the width of the top portion are substantially the same.
