Abstract
Abstract A drain pan for radiators and cooling systems includes a base panel which is molded or otherwise formed into a coffer shape defined by upstanding side walls extendings continuously about the perimeter of the base panel. The side walls include an inwardly extending shoulder spaced slightly above the base panel to support a grid formed of a plurality of upwardly extending panels. The upstanding panels are equally spaced and oriented parallel to perpendicular axes to form a rectilinear matrix. The base panel includes concave recesses at the corners of the coffer to accommodate wheels or rollers affixed thereto.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
A drain receptacle for receiving effluent from a vehicle, comprising a pan having a base panel, a plurality of side walls extending upwardly from the perimeter of said base panel and formed integrally therewith, said side walls extending continuously about said base panel and defining therewith an upwardly opening coffer, at least one of said side walls including a shoulder extending into said coffer and disposed in longitudinal fashion along said side wall, lattice means disposed in said coffer for attenuating and arresting wave motion in and spattering from liquid contained in said coffer, said lattice means including at least one edge impinging on and supported by said shoulder, said base panel including a plurality of corners and a plurality of upwardly extending concave wall members, each disposed at one of said corners and extending between the sidewalls converging thereat.
Claim 2
Dependent Claim
140 words
A drain receptacle for receiving effluent from a vehicle, comprising a pan having a base panel, a plurality of side walls extending upwardly from the perimeter of said base panel and formed integrally therewith, said side walls extending continuously about said base panel and defining therewith an upwardly opening coffer, at least one of said side walls including a shoulder extending into said coffer and disposed in longitudinal fashion along said side wall, lattice means disposed in said coffer for attenuating and arresting wave motion in and spattering from liquid contained in said coffer, said lattice means including at least one edge impinging on and supported by said shoulder, said base panel including a plurality of corners and a plurality of upwardly extending concave wall members, each disposed at one of said corners and extending between the sidewalls converging thereat.
Claim 3
Dependent Claim
35 words
The drain receptacle of claim 1, wherein said lattice means includes a plurality of upwardly extending panels disposed in spaced apart, intersecting fashion, said upwardly extending panels being substantially equal in height to said sidewalls.
Claim 4
Dependent Claim
37 words
The drain receptacle of claim 1, wherein each of said concave wall members defines a corner recess, and further including a plurality of wheel assemblies, each secured in subjacently depending fashion in one of said corner recesses.
Claim 5
Dependent Claim
17 words
The drain receptacle of claim 1, wherein said base panel includes a resealable drain port extending therethrough.
Claim 6
Dependent Claim
27 words
The drain receptacle of claim 1, wherein said shoulder extends continuously about all of said side walls and supports a plurality of edges of said lattice means.
Claim 7
Dependent Claim
41 words
The drain receptacle of claim 5, wherein said shoulder is spaced closely and superjacently with respect to said base panel to define a narrow, laterally extending open flow space between said base panel and the lower edge of said lattice means.
Claim 8
Dependent Claim
30 words
The drain receptacle of claim 1, wherein each of said sidewalls includes a lip at the upper distal portion thereof, said lip extending obliquely upwardly and outwardly from said sidewall.
Claim 9
Dependent Claim
22 words
The drain receptacle of claim 2, wherein said lip also includes a subjacently depending portion extending substantially parallel to said side wall.
