Definitions

  • the present invention relates generally to speed bumps and more particularly to one-way speed bumps which control both the speed and direction of vehicular traffic.
  • Speed bumps are typically dimensioned so that a vehicle may pass over at a relatively slow speed without jarring the driver or causing damage to the vehicle.
  • the present invention provides a one-way speed bump for controlling both direction and speed of traffic.
  • the speed bump has a shallow front face and a steep rear face. Vehicles approaching the front face of the speed bump are allowed to pass over the speed bump at a controlled rate of speed. Vehicles attempting to pass from the wrong direction will engage the steep rear face of the speed bump. This will cause the vehicle to be jarred more so than if the vehicle traveled the correct direction. Indicia may be provided on the steep rear face to warn drivers that are considering traveling in the wrong direction to not go the wrong way.
  • a speed bump comprising a bottom surface, a front face comprising a relatively shallow angle measured from the bottom surface structured and arranged to allow vehicular traffic approaching the front face to pass over the speed bump and a rear face comprising a relatively steep angle measured from the bottom surface structured and arranged to deter vehicular traffic approaching the rear face from passing over the speed bump.
  • FIG. 1 illustrates a perspective view of a one-way speed bump according to one embodiment of the present invention showing the front face, top portion and anchor holes.
  • Fig. 2 illustrates a top view of the speed bump of Fig. 1.
  • Fig. 3 illustrates a rear view of the speed bump of Fig. 1 showing the rear face of the speed bump.
  • Fig. 4 illustrates a side view of a one-way speed bump showing the recess, dimensions, Hi, H 2 , H 3 , Wi, W 2 , and angles ⁇ and ⁇ according to one embodiment of the present invention.

  • Fig. 7 is a perspective view of a one-way speed bump showing the rear face, recess and indicia according to one embodiment of the present invention.
  • Fig. 8 is cross-sectional perspective view of the speed bump along one of the anchor holes showing a means for mounting the speed bump to the pavement including an anchor and bolt according to one embodiment of the present invention.
  • a one-way speed bump 1 according to one embodiment of the present invention shown in Figs. 1-3.
  • the speed bump 1 has a generally flat bottom surface 2, which faces the ground.
  • the ground may comprise pavement.
  • the term "pavement” as used herein is not meant to be one of limitation and can be, for example, a roadway, highway, aisle way, row or parking lot.
  • the speed bump 1 may be positioned to traverse all or a portion of a road.
  • road may be used interchangeably with aisle or any other surface upon which vehicles travel.
  • the length of the speed bump, shown as L in Fig. 1, varies depending on the on the width of the road and may be of whatever length is necessary to control traffic.
  • the speed bump may have anchor hole 12 with countersunk portions 14. Bolts (not shown in Figs. 1-3) may pass through the anchor holes 12 to affix the speed bump 1 to the pavement.
  • the speed bump 1 has a front face 4 having a relatively shallow front angle.
  • the speed bump 1 may have sides 3 at each end.
  • the shallow front face 4 is the face of the speed bump 1 that a driver sees if approaching from the correct direction.
  • the shallow front face 4 is designed to allow a vehicle traveling at a safe speed and in the correct direction to pass over the speed bump with little effect on the vehicle or driver.
  • the shallow front face 4 may be set at an acute angle, shown as ⁇ in Fig. 4, relative to the bottom, for example, an angle of about 10° to about 35°, typically about 15°.
  • the speed bump 1 also has a rear face 6 having a relatively steep angle which impedes traffic going in the wrong direction. Even at a slow speed, the steep rear face 6 of the speed bump acts as a significant obstacle and deterrent for vehicles traveling in the wrong direction.
  • the steep rear face 6 is positioned at an angle, shown as ⁇ , relative to the bottom, for example, about 35° to about 100°, typically about 60°.
  • a top portion 8 may be located between the rear face 6 and front face 4.
  • the top portion 8 is a substantially flat surface generally parallel to the ground or pavement.
  • the top portion 8 may have a dimension, shown as W 2 , of for example 0 inch to 6 inches, for example 2.1 inches.
  • the top portion 8 may have a radiused width or radially transition from the front face 4 to the rear face 6.
  • the substantially flat front face 4 and rear face 6 may be replaced with curved/or faceted surfaces so as long as the overall angle of each surface is more shallow on the front face 4 than the rear face 6.
  • the overall angle refers to an angle relative to the bottom and a best-fit plane passing through the face.
  • the dashed lines in Fig. 5 illustrate examples of best-fit planes for the front face 4 and the rear face 6.
  • the speed bump 1 has an overall height, shown as Hj, sufficient to provide an impediment to vehicles traveling in the wrong direction or at a high speed in either direction.
  • Hi can be, for example, between 1 1 A and 6 inches, for example about 2.5 inches.
  • the shallow front face 4 and the bottom 2 of the speed bump 1 may be connected by a transition region, such as a short vertical edge 10 as shown in Fig. 4.
  • the vertical edge 10 may have a height, shown as H 2 , of for example 0 inch to 1 1 A inches, for example about 0.5 inch.
  • H 2 the height, shown as H 2 , of for example 0 inch to 1 1 A inches, for example about 0.5 inch.
  • the rear face 6 and the bottom 2 of the speed bump 1 may be connected by a transition region, such as a short vertical edge 10 as shown in Fig. 4.

  • the anchor holes 12 are spaced along the length of the speed bump 1 to adequately secure the speed bump 1 to the pavement. In one embodiment, the anchor holes are spaced 30 inches apart.
  • Countersunk portions 14 are provided to transition from the sloped surface of the front face 4 to the anchor holes 12.
  • the countersunk portions 14 have a bottom that is substantially parallel to the pavement so that the head of an anchor bolt may rest flushly thereon.
  • warning indicia 20 can be seen in recess 16.
  • the warning indicia 20 may be painted on the recess 16 or may consist of a label, stencil or any other means of marking the surface so that a driver approaching from the rear face 6 is able to see the indicia.
  • the warning indicia 20 are raised or recessed letters molded as part of the speed bump 1.
  • the warning indicia may recite for example "WRONG WAY" or "DO NOT ENTER". It is also contemplated that other signage could be on the pavement or other surface in front of the steep rear face 6.
  • Speed bump 1 may be attached to the pavement using spikes, lag bolts or other hardware.
  • pre-drilled holes 26 are aligned with the anchor holes 12.
  • the anchor 24 may be an expansion type anchor secured in the pre-drilled holes.
  • the anchor 24 has female threads for receiving a bolt 22.
  • the bolt 22 passes through a washer 23, through the anchor hole 12 and into the anchor 24 to hold the speed bump 1 in place.
  • the speed bump 1 is removable when the bolts 22 are removed.
  • Threaded plugs (not shown) may be provided with the anchors 24. The threaded plugs may be installed in the anchors 24 when the speed bump 1 and bolts 22 are removed.
  • the anchors 24 do not become packed with dirt and debris while the speed bump 1 is removed. This provides for easy installation of the bolts 22 when the speed bump 1 is replaced. The ability to remove and reinstall the speed bump 1 is helpful in climates where snowfall is likely and plowing of snow is needed.
  • the speed bump 1 may be made of plastic to allow the weight to be kept low while still maintaining durability. However, other materials, such as, steel, aluminum, concrete and asphalt may be used in fabrication of the speed bump 1 so long as the structure remains substantially non-collapsible, i.e. the speed bump 1 should be able to withstand vehicular traffic without collapsing or substantial deformation. It has been contemplated that the speed bump 1 may be of modular or one-piece construction.
