Wheel arrangement for swimming pool cleaner
First Claim
1. A pool cleaner for cleaning a pool comprising:
- a housing 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 pair of wheels mounted relative to the front end of said housing, the first pair of wheels including a first wheel being pivotally mounted relative to the first side of the housing and a second wheel being pivotally mounted relative to the second side of said housing;
a tie rod operatively mounted relative to the first wheel and the second wheel 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 the first 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.

Abstract
A pool cleaner for cleaning a pool includes a housing with an upper surface and downwardly projecting sidewalls extending from the upper surface for defining a front, a rear, a first and a second side of the housing. A first pair of wheels includes a first wheel being pivotally mounted relative to the first side of the housing and a second wheel being pivotally mounted relative to the second side of the housing. A tie rod is operatively mounted relative to the first wheel and the second wheel. A second pair of wheels is mounted on the rear end of the housing. As the pool cleaner traverses a pool surface and the first or second wheel is moved to be at a predetermined angular relationship relative to the housing, the tie rod ensures that the first and second wheels are at substantially the same angular relationship relative to the housing.

-
a housing including an upper surface and sidewalls extending from the upper surface for defining a front end, a rear end, a first side and a second side of said housing;
a first wheel mounted relative to the front end of said housing and being pivotally mounted relative to the first side of the housing;
a second wheel mounted relative to the front end of said housing and being pivotally mounted relative to the second side of said housing;
a tie rod operatively positioned relative to the first wheel and the second wheel 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 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 or the first wheel for ensuring that the first and second wheels are at substantially the same angular relationship relative to said housing. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
