Claims
- 1. A vehicle warning system comprising,
- a base structure adapted to be mounted on a vehicle traffic lane of a highway surface,
- a plurality of raised bump portions to said base structure transversely of the direction of travel of the vehicle to produce a warning bump when impacted by the tires of a vehicle,
- wherein the base structure includes a rigid mounting frame having a plurality of spaced apart substantially parallel longitudinal frame members, having a plurality of rigid cross members fixed to the longitudinal frame members and extending therebetween the ridges being mounted on selected cross frame members and extending upwardly a substantial distance above the pavement surface when the mounting frame is laid thereon,
- and wherein the frame members are constructed of generally flat continuous material and the cross frame members are spaced a sufficient distance apart to permit the tires of a vehicle to contact the pavement in the space provided between the cross frame members and the raised bump portions are securely fixed to selected cross frame members.
- 2. The structure set forth in claim 1 wherein the flat frame members and the bump portions are formed from steel material wherein the bump portions are welded to the cross frame members.
- 3. The structure set forth in claim 1 wherein the raised bump portions are formed from a plurality of segments arranged in slightly spaced apart end-to-end relationship to facilitate flexing of the cross frame members.
- 4. The structure set forth in claim 1 wherein the raised bump portions are in the shape of an inverted "V".
- 5. The structure set forth in claim 1 wherein the raised bump portions are in the shape of upwardly curved arcuate segments.
- 6. The structure set forth in claim 1 wherein the mounting frame is hingedly connected to a similar frame to permit compact storage when not in use.
- 7. The structure set forth in claim 1 wherein the rigid cross frame members are positioned in a plurality of groups, the frame members in each group being more closely spaced than the space between adjacent groups and wherein,
- the raised portions constitute rib elements fixed to the respective cross members and being less than 5/8" in height.
- 8. The structure set forth in claim 7 wherein the rib elements are in the form of half-round segments with the flat side securely respectively fixed to the top surface of the cross frame members.
- 9. The structure set forth in claim 7 wherein the rib elements are in the form of short spaced apart segments to permit flexing of the cross frame members.
- 10. The structure set forth in claim 1 wherein a pair of mounting frames are provided in side-by-side relationship to extend across substantially the full width of a single portion of highway, with means for removably connecting adjacent frame members.
- 11. The structure set forth in claim 10 wherein the ridges are in the form of hollow members having a connecting open-ended cross web fixed across the open-inner end thereof adjacent to the frame to be joined, and
- a connecting unit fixed to the section adjacent to the open-ended cross web and having connecting means for positively interconnecting the cross web of one section with the adjacent portion of the longitudinal frame member of the adjacent frame section.
- 12. The structure set forth in claim 11 wherein the connecting unit is in the form of a hook member positioned behind the cross web secured to one section and securely attached to a portion of the side-by-side frame section.
- 13. The structure set forth in claim 10 wherein raised bump portions of the two sections are staggered to produce alternate impact with the tires on opposite sides of the vehicle.
