Abstract

A drain support pan assembly has a drain body support pan which has a rectangular-shaped body connected to a rectangular-shaped drain receptacle body for use in floor drains. The distance between the support pan and receptacle body can be adjusted according to the depth of the floor space by selecting a predetermined length for the fasteners. The support pan has a center passageway for receiving a drain pipe and several slots that align with threaded passageways in the receptacle body for receiving the fasteners. The support pan contains concentric knock-out sections which can be removed for enlarging the diameter of the center passageway to accommodate varying diameter drain pipes or pipe connections for particular use in a deep floor space, and also has a rectangular knock-out section which can be removed for receiving the rectangular-shaped drain receptacle for use in a narrow floor space.

Claims (33)

1. A drain body support pan adapted to be connected to a receptacle body of a drain, the drain body support pan comprising:

a body having an inner surface and an outer surface and defining a first portion and a second portion, said first portion of said body defining a peripheral edge, said second portion of said body attached to the peripheral edge of said first portion and axially extending from said peripheral edge of said first portion,

wherein said inner surface of said first portion and said second portion of said body define an interior cavity,

wherein said first portion of said body of said drain body support pan defines a center passageway spaced inwardly of said peripheral edge of said first portion of said drain body support pan and adapted to receive a pipe or pipe connection,

wherein at least one first geometric shaped knock-out section is defined on said first portion adjacent said center passageway of said body of said drain body support pan and is adapted to be removed from said drain body support pan,

wherein at least one second geometric shaped knock-out section is defined on said first portion outwardly of said at least one first geometric shaped knock-out section and inwardly of said peripheral edge of said first portion of said body of said drain body support pan and is adapted to be removed from said support pan, said first geometric shaped knock-out section having a different geometric shape than the second geometric shaped knock-out section,

wherein said second geometric shaped knock-out section is configured to receive at least a portion of the drain receptacle body of the drain; and

wherein said drain body support pan is configured for use for installing a drain support assembly in both a narrow floor structure and/or a deep floor space.

2. The drain support plate as claimed in claim 1 , wherein said first portion of said body of said drain body support pan contains at least one slot adapted to be aligned with said receptacle body for receiving a fastener for attaching said receptacle body to said body of said drain body support pan.

3. The drain support plate as claimed in claim 1 , wherein at least two first geometric shaped concentric knock-out sections are defined on said first portion adjacent said center passageway of said body of said support pan.

4. The drain body support pan as claimed in claim 3 , wherein said at least two first geometric shaped knock-out sections are defined by a plurality of perforations extending from said outer surface to said inner surface of said first portion and adapted for removal of one or more first geometric shaped knock-out sections for enlarging the diameter of said center passageway of said body of said support pan.

5. The drain body support pan as claimed in claim 4 , wherein said center passageway is circular.

6. The drain body support pan as claimed in claim 5 , wherein said at least one second geometric shaped knock-out section is defined by a plurality of perforations extending from said outer surface to said inner surface of said first portion adapted for removal of said second geometric shaped knock-out section which involves removal of said one or more first geometric shaped knock-out sections and said center passageway of said body of said support pan.

7. The drain body support pan as claimed in claim 1 , wherein said body is rectangular.

8. The drain body support pan as claimed in claim 7 , wherein said first geometric shaped knock-out section is circular.

9. The drain body support pan as claimed in claim 7 , wherein said second geometric shaped knock-out section is rectangular.

10. The drain body support pan as claimed in claim 9 , wherein said second geometric shaped knock-out section is square.

11. The drain body support pan as claimed in claim 9 , wherein said first geometric shaped knock-out section is circular.

12. The drain body support pan as claimed in claim 1 , wherein said first geometric shaped knock-out section has a first area and said second geometric shaped knock-out section has a second area, the first area being less than the second area.

13. The drain body support pan as claimed in claim 3 , wherein said at least two first geometric shaped concentric knock-out sections are geometrically similar.

14. A drain body support pan assembly comprising:

a receptacle body having a drain pipe and/or a pipe connection, and

a drain support pan connected to the receptacle body, said drain support pan comprising:

a body having an inner surface and an outer surface and defining a first portion and a second portion, said first portion of said body defining a peripheral edge, said second portion of said body attached to the peripheral edge of said first portion and axially extending from said peripheral edge of said first portion,

wherein said inner surface of said first portion and said second portion of said body define an interior cavity,

wherein said first portion of said body of said drain body support pan defines a center passageway spaced inwardly of said peripheral edge of said first portion of said drain body support pan and adapted to receive the pipe or pipe connection,

wherein at least one first geometric shaped concentric knock-out section is defined on said first portion adjacent said center passageway of said body of said drain body support pan and is adapted to be removed from said drain body support pan,

wherein at least one second geometric shaped knock-out section is defined on said first portion outwardly of said at least one first geometric shaped knock-out section and inwardly of said peripheral edge of said first portion of said body of said drain body support pan and is adapted to be removed from said support pan, said first geometric shaped knock-out section having a different geometric shape than the second geometric shaped knock-out section, and

wherein said drain body support pan is configured for use for installing a drain support assembly in both a narrow floor structure and/or a deep floor space; and

wherein said second geometric shaped knock-out section is configured for receiving at least a portion of said receptacle body.

15. The drain support pan assembly as claimed in claim 14 , further comprising at least one fastener connecting said receptacle body to said drain support pan.

16. The drain support plate assembly as claimed in claim 15 , wherein said first portion of said body of said drain body support pan contains at least one slot adapted to be aligned with said receptacle body for receiving said at least one fastener for connecting said receptacle body to said drain body support pan, and

wherein said fastener has a length that is varied depending on the depth of the floor space in which said drain support plate assembly is installed.
