FIG. 1 is a front perspective view of a sink showing my new design;
FIG. 2 is a front view thereof;
FIG. 3 is a rear view thereof;
FIG. 4 is a side view thereof;
FIG. 5 is a side view of the opposite side of FIG. 4;
FIG. 6 is a top view thereof; and,
FIG. 7 is a bottom view thereof.
The broken lines using uniform dashes shown in the drawings illustrate portions of a sink that form no part of the claimed design.
The broken lines using uneven dashes (i.e., the dot-dashed lines) in FIG. 1 indicate bounds of the claimed design and form no part thereof. Thus, the area inside the dot-dashed rectangle does not indicate a wall or surface that is part of the claimed design.
