Composite water closet flanges and methods for forming the same

A composite water closet flange comprising:

• a) a hub member having a hub member axis and including a connecting portion and a through-passage extending through the connecting portion, the connecting portion including:
• 1) a radially extending shoulder;
• and
• 2) a plurality of radially extending locking tabs axially spaced apart from the shoulder;
• and
• b) a ring member mounted on the hub member and including:
• 1) a plurality of engagement portions interposed between the shoulder and respective ones of the locking tabs;
• and
• 2) a key slot defined in the ring member, wherein the key slot is sized and configured to receive at least one of the plurality of locking tabs therethrough.

A hub member for use with a ring member having a key slot to form a composite water closet flange, the hub member having a hub member axis and comprising a connecting portion and a through-passage extending through the connecting portion, the connecting portion including:

• a) a shoulder extending radially outwardly;
• b) a primary locking tab extending radially outwardly and axially spaced apart from the shoulder, the primary locking tab being sized and configured to allow the primary locking tab to pass through the key slot;
• and
• c) a secondary locking tab extending radially outwardly and axially spaced apart from the shoulder, the secondary locking tab being sized and configured to prevent the secondary locking tab from passing through the key slot.

A method of assembling a water closet flange, the method comprising:

• a) providing a hub member having a hub member axis and including a connecting portion and a through-passage extending through the connecting portion, the connecting portion including:
• 1) a shoulder extending radially outwardly;
• and
• 2) first and second locking tabs extending radially outwardly and axially spaced apart from the shoulder;
• b) providing a ring member including an inner peripheral portion defining an opening and a key slot defined in the inner peripheral portion and communicating with the opening, wherein the key slot is sized and configured to receive at least one of the first and second locking tabs therethrough;
• c) positioning the connecting portion of the hub member in the opening of the ring member such that the inner peripheral portion is interposed between the second locking tab and the shoulder;
• d) positioning the connecting portion of the hub member in the opening of the ring member such that the first locking tab is axially aligned with the key slot;
• and
• e) axially displacing the first locking tab through the key slot.
