Abstract:
1. A pool cleaner for cleaning a pool comprising: a housing for the pool cleaner including an upper surface and downwardly projecting sidewalls extending downwardly from the upper surface for defining a front end, a rear end, a first side and a second side of said housing; a first mounting mechanism including a first arm and a second arm mounted on the first side relative to the front end of said housing for the pool cleaner; a first wheel being mounted on said second arm of said first mounting mechanism for independent pivotal movement relative to the first side of the housing; a second mounting mechanism including a first arm and a second arm mounted on the second side relative to the front end of said housing for the pool cleaner; a second wheel being mounted on said second arm of said second mounting mechanism for independent pivotal movement relative to the second side of said housing; a tie rod operatively mounted relative to the second arm of the first mounting mechanism and the second arm of the second mounting mechanism for ensuring substantially the same angular relationship of the first wheel and the second wheel relative to said housing; and a second pair of wheels mounted relative to the rear end of said housing; wherein when the pool cleaner traverses a pool surface and either the first wheel or the second wheel is moved to be at a lateral angular relationship relative to the housing, the tie rod imparts movement to the second wheel for ensuring that the first and second wheels are at substantially the same angular relationship relative to said housing; wherein the first and second wheels project outwardly relative to the front end of said housing for enabling either the first or second wheels to engage a wall surface of a pool for imparting a turning motion to the first wheel or the second wheel for changing an angular relationship of the wheels relative to said housing.
