I claim the ornamental design for a handle for a scrub brush, as shown and described.
FIG. 1 is a side view of a handle for scrub brush wherein the handle has been broken away beneath a knob to indicate indeterminate length showing my new design;
FIG. 2 is top down view thereof;
FIG. 3 is a side view thereof with the handle rotated on its axis 90 degrees clockwise from the position shown in (FIG. 1), and wherein the handle has been broken away beneath a knob to indicate indeterminate length;
FIG. 4 is a sectional view thereof, taken along lines 4-4 in FIG. 1;
FIG. 5 is another sectional view thereof, taken along lines 5-5 in FIG. 3;
FIG. 6 is a cross-sectional view thereof taken along lines 6-6 of (FIG. 1); and,
FIG. 7 shows the claimed design in an enviromental setting.
The broken lines in the drawings illustrate environmental subject matter only and form no part of the claimed design. The contour lines including the horizontal and concentric lines on the spherical end portion and the vertical lines on the handle portion indicate reflectivity and surface shading, respectively, and form no part of the claimed design. The handle for a scrub brush is shown with a symbolic break in its length. The appearance of any portion of the handle for a scrub brush between the break lines forms no part of the claimed design.
