Claims20
A structure positioned adjacent to a floor surface for connecting to a drain pipe, the structure comprising:
- a head having an opening leading to an inside surface defining a passageway, the inside surface having a tab extending therefrom, the tab disposed below and in spaced apart relation to the opening;
- a leveling member having a head with a with slots defined therein for turning the leveling member, the leveling member supported by the tab and configured and arranged to be displaceable in a first direction relative to the tab;
- a frame having an upper surface and a lower surface, the frame having a bracket extending downward and inward from the lower surface, the bracket having a distal portion configured and arranged to attach the frame to the leveling member at a position below the head of the leveling member.
A drain assembly, comprising:
- a head having a threaded shank and having an upstream opening leading to an inside surface defining a passageway, the inside surface having a tab extending therefrom, the tab disposed below and in spaced apart relation to the upstream opening;
- a leveling member having a head with a with slots defined therein for turning the leveling member, the leveling member supported by the tab and configured and arranged to be displaceable in a first direction relative to the tab;
- a frame having an upper surface and a lower surface, the frame having a bracket angled downward and inward from the lower surface, the bracket having a distal portion configured and arranged to attach the frame to the leveling member at a position below the head of the leveling member;
- a collar having an internal surface having internal threads configured and arranged to engage with the threaded shank on the head such that the head threadingly engages with the collar and is capable of displacement relative to the collar;
- a lower body configured and arranged to receive the collar, the lower body defining a passageway therethrough;
- and,
- a drain pipe secured to the lower body.
