Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
177 words
A device for collecting leakage from a dishwashing machine including a single structure, said structure comprising: sidewalls cooperating with front and rear walls and a bottom surface to form a collection basin with a hollow interior and an open top, said front wall being fixed and extending a distance intermediate the height of said sidewalls forming a cutout portion necessary to provide a clearance to accommodate passage of the diswashing machine pump means or other components which typically extend beneath the dishwashing machine, said bottom surface being inclined downwardly toward said rear wall; means associated with said inclined bottom surface for effectively removing the leakage collecting in said basin; and said sidewalls having outer flange surfaces extending therefrom for providing a guide surface for guiding support legs of the dishwashing machine, said support legs movable along said flange surfaces and guided by the sidewall outer wall surfaces to maintain the dishwashing machine in proper alignment while making installation and removal exceedingly easy when there is only a slight gap between the dishwashing machine and wall structure means.
Claim 2
