Abstract

A mobile barrier is shown having first and second platforms, at least one of the first and second platforms engaged with an axle and a set of wheels; a safety wall assembly, having a mechanism for translation of the safety wall from one side of the platforms to another, the safety wall further having telescoping first and second portions allowing the safety wall assembly to expand and retract in length along the longitudinal axis of the mobile barrier; a plurality of variable length braces connected to the platforms and the safety wall, which expand and retract as the safety wall moves from one side of the platforms to the other.

First claim

1 . A mobile barrier comprising:
first and second platforms, each of said first and second platforms having a right edge and a left edge, at least one of the first and second platforms engaged with an axle and a set of wheels; a safety wall assembly, said safety wall assembly having a mechanism for translation of the safety wall assembly; wherein said safety wall assembly is comprised of: first and second wall sections, each of said first and second wall sections having a platform facing end and an opposing engagement end, wherein the second wall section and the first wall section are telescopically engaged with each other at their respective engagement ends; a first, second, third and fourth variable length braces, each of said first, second, third and fourth variable length braces connected between one of said platforms and one of said wall sections; wherein each of the first, second, third and fourth variable length braces expand and retract as the safety wall assembly moves from the position aligned with the right edge of the first and second platforms to the position aligned with the left edge of the first and second platforms.

2 . The mobile barrier of claim 1 , wherein the mechanism for translation of the safety wall assembly is two motor-driven rack and pinion assemblies located at each end of the safety wall assembly.

3 . The mobile barrier of claim 1 , wherein the mechanism for translation of the safety wall assembly is two motor-driven rollers riding in channels located at each end of the safety wall assembly.

4 . The mobile barrier of claim 1 , wherein the first, second, third and fourth variable length braces have a detent mechanism that actuates at a fully retracted position, a half-way extended position and a fully extended position, and wherein the actuation of the detent mechanism prevents the respective variable length braces from further extending or retracting.

5 . The mobile barrier of claim 4 , wherein the first, second, third and fourth variable length braces are further secured into each of the fully retracted position, the half-way extended position and the fully extended position by a pin that passes through holes in the respective variable length braces, said pin preventing further extension or retraction.

6 . The mobile barrier of claim 1 , wherein the mechanism for translation of the safety wall assembly is hydraulic cylinders disposed in each of the first, second, third and fourth variable length braces.

7 . The mobile barrier of claim 6 , wherein the safety wall assembly has rollers disposed at both ends thereof, and said rollers ride in channels located on the interior surfaces of the first and second platforms respectively.

8 . The mobile barrier of claim 7 , wherein a plurality of releasable stops retain the safety wall assembly in a first position aligned with the right edge of the first and second platforms, a second position disposed equidistant between the right and left edges of the first and second platforms, and a third position aligned with the left edge of the first and second platforms.

9 . The mobile barrier of claim 8 , wherein the safety wall assembly is further secured in the first, second or third positions by pins that pass through holes in the safety wall assembly and into a corresponding holes in the first and second platforms.

10 . A mobile barrier comprising:
first and second platforms, each of said first and second platforms having a right edge and a left edge, at least one of the first and second platforms engaged with an axle and a set of wheels; top and bottom safety wall assemblies, each of said top and bottom safety wall assemblies having a mechanism for translation of the respective safety wall assembly; wherein the top safety wall assembly is comprised of: a first top wall section, having a platform facing end and an opposing engagement end, and a second top wall section having a platform facing end and an opposing engagement end, wherein the first and second top wall sections are telescopically engaged with each other at their respective engagement ends; wherein the bottom wall assembly is comprised of: a first bottom wall section, having a platform facing end and an opposing engagement end, and a second bottom wall section having a platform facing end and an opposing engagement end, wherein the first and second bottom wall sections are telescopically engaged with each other at their respective engagement ends; first, second, third, fourth, fifth, sixth, seventh and eighth variable length braces, each of said variable length braces connected between one of the platforms and one of the wall sections; wherein each of the first, second, third, fourth, fifth, sixth, seventh and eighth variable length braces expand and retract as the respective top and bottom safety wall assemblies move from the position aligned with the right edge of the first and second platforms to the position aligned with the left edge of the first and second platforms.

11 . The mobile barrier of claim 10 , wherein the mechanism for translation of the top and bottom safety wall assemblies is two motor-driven rack and pinion assemblies located at each end of the respective safety wall assemblies.

12 . The mobile barrier of claim 10 , wherein the mechanism for translation of the top and bottom safety wall assemblies is motor-driven rollers riding in channels located at each end of the safety wall assembly.

13 . The mobile barrier of claim 10 , wherein the first, second, third, fourth, fifth, sixth, seventh and eighth variable length braces have a detent mechanism that actuates at a fully retracted position, a half-way extended position and a fully extended position, and wherein the actuation of the detent mechanism prevents the respective variable length braces from further extending or retracting.

14 . The mobile barrier of claim 13 , wherein the first, second, third, fourth, fifth, sixth, seventh and eighth variable length braces are further secured into each of the fully retracted position, the half-way extended position and the fully extended position by a pin that passes through holes in the respective variable length braces, said pin preventing further extension or retraction.

15 . The mobile barrier of claim 10 , wherein the top and bottom safety wall assemblies each use mechanically different mechanisms for translation.

16 . The mobile barrier of claim 10 , wherein the first, second, third, fourth, fifth, sixth, seventh and eighth variable length braces are received in pockets on an exterior surface of the top and bottom safety wall assemblies.

17 . The mobile barrier of claim 10 , wherein the mechanism for translation of the top and bottom safety wall assemblies is hydraulic cylinders disposed in each of the first, second, third, fourth, fifth, sixth, seventh and eighth variable length braces.

18 . The mobile barrier of claim 17 , wherein the top and bottom safety wall assemblies have rollers disposed at both ends thereof, and said rollers ride in channels located on the interior surfaces of the first and second platforms respectively.

19 . The mobile barrier of claim 17 , wherein a plurality of releasable stops retain the top and bottom safety wall assemblies in a first position aligned with the right edge of the first and second platforms, a second position disposed equidistant between the right and left edges of the first and second platforms, and a third position aligned with the left edge of the first and second platforms.
