Push through retainer connection with integrated hinging seal

A connection assembly adapted to join a surface element to an underlying support structure while maintaining a substantially zero gap abutting relation between the surface element and the support structure during use, the connection assembly comprising:

• a press-in retainer adapted for insertion into an acceptance opening in the support structure to establish operative connecting engagement between the surface element and the support structure, the retainer including a retainer head and a clip portion of arrowhead configuration projecting outwardly away from the retainer head, wherein the retainer head includes an upper platform, an annular platform defining a lower collar having a perimeter edge positioned in spaced relation below the upper platform, and a connective neck structure extending between the upper platform and the lower collar, wherein the clip portion comprises a central stem extending downwardly away from the lower collar such that the lower collar is oriented substantially perpendicular to an axis defined by the stem, a pair of flexible wings extending in upward angled relation away from the central stem, the flexible wings terminating at wing tips disposed in spaced relation below the lower collar, wherein the flexible wings each have a dog-leg configuration including a radially inwardly angled segment defining an angled biasing surface disposed between a radially outwardly angled segment and a free end, the angled biasing surface being adapted to press against an interior surface of the acceptance opening to urge the retainer downwardly into the acceptance opening, the retainer further including a monolithic seal disposed about the perimeter edge of the lower collar, the seal having a durometer lower than the lower collar, the seal including a body portion at least partially surrounding the perimeter edge and the seal further including an integral hinging sealing foot projecting downwardly and radially outwardly away from the body portion to a free edge such that the sealing foot is disposed entirely outboard from the underside of the lower collar and forms an obtuse angle relative to the underside of the lower collar, and wherein the sealing foot flexes about a living hinge while remaining outboard from the lower collar and maintaining sliding contact with the support panel in response to applied pressure between the seal and the support panel during use;
• a preformed surface element having a contact surface configured to abut the support structure in a substantially gapless relation during use;
• and
• an intermediate connector operatively connected to the surface element and adapted to receive and retain the retainer head such that upon insertion of the retainer into an acceptance opening in the support panel, an operative connection is established between the surface element and the support structure, wherein the surface element is configured such that when the retainer is held between the intermediate connector and the support structure, the contact surface of the surface element is at an elevation such that it abuts the support structure while the sealing foot is in contacting relation with the support structure and the lower collar remains spaced in elevated relation away from the support structure.

A method of connecting a surface element to an underlying support structure while maintaining a substantially zero gap abutting relation between the surface element and the support structure during use, the method comprising:

• providing a press-in retainer adapted for insertion into an acceptance opening in the support structure to establish operative connecting engagement between the surface element and the support structure, the retainer including a retainer head and a clip portion of arrowhead configuration projecting outwardly away from the retainer head, wherein the retainer head includes an upper platform, an annular platform defining a lower collar having a perimeter edge positioned in spaced relation below the upper platform, and a connective neck structure extending between the upper platform and the lower collar, wherein the clip portion comprises a central stem extending downwardly away from the lower collar and a pair of flexible wings extending in upward angled relation away from the central stem, the flexible wings terminating at wing tips disposed in spaced relation below the lower collar, wherein the flexible wings each have a dog-leg configuration including a radially inwardly angled segment defining an angled biasing surface disposed between a radially outwardly angled segment and a free end, the angled biasing surface being adapted to press against an interior surface of the acceptance opening to urge the retainer downwardly into the acceptance opening, the retainer further including a monolithic seal disposed about the perimeter edge of the lower collar, the seal having a durometer lower than the lower collar, the seal including a body portion at least partially surrounding the perimeter edge and the seal further including an integral hinging sealing foot projecting downwardly and radially outwardly away from the body portion to a free edge such that the sealing foot is disposed entirely outboard from the underside of the lower collar and forms an obtuse angle relative to the underside of the lower collar, and wherein the sealing foot flexes about a living hinge while remaining outboard from the lower collar and maintaining sliding contact with the support panel in response to applied pressure between the seal and the support panel during use;
• providing a preformed surface element having a contact surface configured to abut the support structure in a substantially gapless relation during use;
• securing the retainer head within an intermediate connector operatively connected to the surface element;
• and
• inserting the retainer into an acceptance opening in the support panel, to establish an operative connection between the surface element and the support structure, wherein the surface element is configured such that when the retainer is held between the intermediate connector and the support structure, the contact surface of the surface element is at an elevation such that it abuts the support structure while the sealing foot is in flexed contacting relation with the support structure and the lower collar remains spaced in elevated relation away from the support structure.
