1. Field of the Invention
The present invention relates to a drain assembly, more particularly, to a drain assembly with an adjustable collar.
2. Description of Related Art
Floor drain assemblies are widely installed in the floors of structures where there will be or is the potential for water to be present. Floor drain assemblies connect the floor to a waste removal system such as a storm or sanitary sewer. A variety of floor drain assemblies also include a collar that is adapted to secure linoleum or other waterproofing material between the collar and the body of the drain assembly.
For instance, U.S. Pat. No. 3,246,582 to Wade et al discloses an adjustable square drain wherein the height of the drain may be adjusted by an adjustable square collar. The square collar is telescopically adjustable. This telescopic adjustment is provided by four set adjustment heights for collar via the use of four different-sized inserted pads.
Also, U.S. Pat. No. 5,408,706 to Barnes discloses a fitting assembly for a vinyl-lined pool. A vinyl liner is sandwiched between a clamping ring and a fitting that is placed in a concrete wall of the pool. A fastener is used to secure the sandwiched connection between the vinyl liner and the ring and fitting.
However, such prior art drains do not include collars that may be adjusted vertically to accommodate for uneven flooring, and to ensure that the top edges of the drain and grate do not protrude from the floor or are sunken into the floor.
Accordingly, a need exists for a drain assembly with an adjustable collar that can be adjusted vertically to accommodate for uneven flooring. A further need exists for a drain assembly that can be installed quickly, easily and efficiently.
The present invention is directed to a drain assembly comprising a receptacle body with a first end and a second end defining a cavity therebetween and an adjustable collar. The first end of the receptacle body forms an opening into the cavity and includes a peripheral step with a connection flange extending substantially perpendicularly therefrom, and a peripheral flange with a substantially horizontal support portion extending away from the connection flange. The connection flange includes a series of passageways for accommodating fastening members oriented in a first direction, and the connection flange and the peripheral flange define a channel therebetween. The adjustable collar includes a first flange positioned adjacent to the connection flange of the peripheral step, and a second flange extending substantially perpendicular from the first flange. The first flange includes a series of holes which align with the series of passageways in the connection flange. A grate supported by the peripheral step of the first end of the receptacle body may be positioned over the opening of the receptacle body.
The passageways may be elongated in a second direction. The first direction may be opposite of the second direction. For instance, the first direction may be horizontal and the second direction may be vertical.
Flooring, waterproofing material, linoleum or any combination thereof may be fitted in the channel between the connection and the peripheral flange and secured between the second flange of the adjustable collar and the peripheral flange by tightening the fastening members positioned in the passageways of the connection flange and the series of holes in the first flange. The passageways in the connection flange allow the height of the adjustable collar to be adjusted to accommodate for uneven flooring.
The peripheral flange may be connected to the first end of the receptacle body. Further, the second end of the receptacle body may be configured to receive a pipe. The grate, adjustable collar and receptacle body may be constructed from stainless steel, and the receptacle body may have a generally rectangular shape.
The present invention is also a method for attaching flooring to a drain assembly. The method includes the steps of providing a drain assembly. The drain assembly includes a receptacle body with a first end and a second end defining a cavity therebetween. The first end forms an opening into the cavity. The receptacle body includes a peripheral step with a connection flange extending substantially perpendicularly therefrom. The connection flange includes a series of passageways for accommodating fastening members oriented in a first direction. The receptacle body also includes a peripheral flange with a substantially horizontal support portion extending away from the connection flange. The connection flange and the peripheral flange define a channel therebetween. The drain assembly also includes an adjustable collar comprising a first flange positioned adjacent to the connection flange of the peripheral step and a second flange extending substantially perpendicular from the first flange. The first flange includes a series of holes which align with the series of passageways in the connection flange. Once the drain assembly has been provided, the method continues by fitting flooring material in the channel between the connection flange and the peripheral flange. Next, the fastening members positioned in the passageways of the connection flange and the series of holes in the first flange of the adjustable collar are tightened thereby securing the flooring between the second flange of the adjustable collar and the peripheral flange.
The passageways may be elongated in a second direction. The first direction may be opposite of the second direction. For instance, the first direction may be horizontal and the second direction may be vertical.
The second end of the receptacle body may be coupled to a pipe. The passageways in the connection flange may be configured to allow the height of the adjustable collar to be adjusted to accommodate for uneven flooring. A grate may be positioned over the opening of the receptacle body. The grate may be supported by the peripheral step.

Drain assembly 1 of the present invention is installed via the following steps. First, drain assembly 1 is positioned in an appropriate sized opening in a floor. Next, flooring material 37 is fitted in channel 29 between connection flange 19 and peripheral flange 21. Flooring material 37 may be any appropriate flooring material such as, but not limited to, linoleum and waterproofing material. Flooring material 37 is then secured between second flange 33 of adjustable collar 11 and peripheral flange 21 by passing fastening members 27 through slots 25 of connection flange 19 and the series of holes 35 in first flange 31 of adjustable collar 11 and then tightening fastening members 27. Vertical slots 25 in connection flange 19 allow the height of adjustable collar 11 to be adjusted to accommodate for uneven flooring. Finally, an appropriate sized pipe 39 is securely fastened via welding or any other appropriate method to opening 36 in second end 7 of receptacle body 3.
Drain assembly 1 is positioned in a floor of a structure where there will be or is the potential for water to be present. Pipe 39 allows drain assembly 1 to connect the floor to a waste removal system such as a storm or sanitary sewer.
Drain assembly 1 preferably provides a fluid tight seal between itself and flooring material 37. Further, slots 25 of connection flange 21 allow for vertical adjustments of adjustable collar 11 to compensate for uneven flooring. This allows for drain assembly 1 to be positioned on a floor without protruding from the floor or creating a recess in the floor and creating a pleasant flat appearance between the interface of flooring material 37 and grate 13 even if flooring material 37 is uneven or sloped adjacent to grate 13.
While the embodiments were described hereinabove in relation to a floor drain assembly, this is not to be construed as limiting as other uses for drain assembly 1 of the present invention have been envisioned, such as for use as a roof drain assembly. Further, while drain assembly 1 has been described as having a generally rectangular shape, this is also not to be construed as limiting as a variety of other configurations of drain assembly 1 have been envisioned, such as circular, triangular and the like.
