FIG. 4 is a left-side view thereof;
FIG. 5 is a right-side view thereof;

The broken line circle at the bottom that is immediately adjacent to the shaded areas and defines an unshaded region represents the bounds of the claim. All other broken lines, which occur outside the boundaries of the claim, are directed to environment. The broken lines form no part of the claimed design. The dot-dash broken lines in the figures represent an unclaimed boundary line and form no part of the claimed design.
