6 Claims.

This invention relates to improvements in sink mountings for installing a standard flat flange type sink in an opening in a drainboard, cabinet top or similar supporting structure.

It is a general object of the invention to provide an improved mounting means adapted for rigidly securing a flat ilange type sink in an opening in a drainboard or cabinet top which mounting means comprises a sealing ring or molding strip of generally T-shaped cross section which is adapted to be positioned between the edge of the sink ange and the edge of the drainboard in overlapped relation with respect to the sink flange and the top of the drainboard and a plurality of adjustable clamping members which are adapted to be positioned beneath the sink and the drainboard to rigidly secure the sealing ring in such relation and to provide a watertight seal between the sink and the drainboard.

It is a more specific object of the invention to provide a sink mounting means of the type described wherein a plurality of clamping members are provided for initially clamping the T- shaped sealing member in overlapped relation with respect to the sink frame, prior to installation of the same as a unit in the aperture in the drainboard.

It is a still more specific object of the invention to provide a sink mounting means for combination with a flat rim type sink which comprises a molding frame of generally T-shaped cross section having a top portion adapted to overlie the sink rim and the edge of the apertured drainboard or cabinet top structure in which the sink is positioned and a plurality of clamping elements for initially securing the molding frame to the sink rim whereby the sink and the molding frame may be installed as a unit in the drainboard or top, the clamping elements each comprising an elongate plate-like portion having an adjusting screw in threaded engagement in an aperture adjacent one end thereof and having a groove extending along the other end thereof which is adapted to receive in interlocking relation a shoulder formation along the lower edge of the molding frame.

These and other objects of the invention will be apparent from a consideration of the preferred form thereof which is shown by way of illustration, in the accompanying drawings, wherein:

Fig. l is a top plan of a sink installed in a drainboard with a mounting means which embodies the principles of the invention; v

of the sink installation Fig. 3 is a section on the line 3 3 of Fig. 1, to an enlarged scale;

Fig. 4 is a perspective View showing, in inverted position, a portion of a molding frame and one of the clamping elements initially securing the same to the rim of the sink;

Fig. 5 is a section on the line 5-5 of Fig. 1, to an enlarged scale; and

Fig. 6 is a perspective view showing a portion of the molding frame secured to the sink rim and the drainboard by one of the clamping elements.

Referring to the drawings there is illustrated a sink Ii! having a flange portion II which is positioned in an aperture I2 provided in a drainboard structure I 3 and which is secured therein by a sealing ring or molding I4 and a plurality of clamping elements I5. The sink I0 is the standard type having an outwardly directed top rim or flange structure II which is rounded at the corners of the sink. The drainboard I3 is a conventional linoleum covered plywood structure which may be a cabinet top or other supporting surface. e

The sealing ring or molding I4 is a one-piece member, preferably of extruded metal, which is adapted'to be positioned around the periphery of the sink flange I I with one side or top portion I6 extending in overlying relation to the top surface of the sink flange I I and with the other side or top portion Il extending in overlying relation to the adjoining top surface of the drainboard I3. The sealing ring I4 includes a depending web or stem portion I8 which is adapted to be positioned in the space between the outer edge of the sink flange I I and the edge of the drainboard I3 which surrounds the aperture l2. The sealing ring web or flange I8 is provided along its lower inner edge with a thickened portion or shoulder formation I 9 extending inwardly thereof and providing bottom 2li and an inwardly facing side edge 2 i. The top edge 22 on the shoulder formation I9 extends'at a slight downward angle towards the main portion of the web i8 so that there is provided a hook-like formation along the bottom edge of the same. The depth of the web I8 is sufficient to bring the bottom edge 2!) approximately'on the level with the bottom edge of the drainboard I 3 in which the sink is mounted and below the bottom surface of the rim II of the sink I0.

In installingfal sink of this character in a drainboard it is convenient, particularly in the case of cabinet tops, to first attach the molding or sealing strip I 4 tothe flange II of the sink I0 and then insertor position the sink and molding as aunit inthe aperture I2.
