Description

FIG. 1 is a rear perspective view of a chainring showing our new design, with a crank arm and chain shown as environment;
FIG. 2 is a rear perspective view of a portion of the chainring in FIG. 1, wherein a chain is shown as environment;
FIG. 3 is front perspective view of a portion of the chainring in FIG. 1, wherein a chain is shown as environment;
FIG. 4 is a close up view of the right side of the chainring portion encompassed by the broken line circle in FIGS. 1, 2 and 3;
FIG. 5 is a close up view of the left side of the chainring portion encompassed by the broken line circle in FIGS. 1, 2 and 3;
FIG. 6 is a close up front view of one of the teeth of the chainring;
FIG. 7 is a close up rear view of the tooth of FIG. 6;
FIG. 8 is a top plan view of a portion of the chainring, wherein the bottom plan view is a mirror image thereof;
FIG. 9 is a rear view of a portion of the chainring;
FIG. 10 is a right side view of a portion of the chainring; and,
FIG. 11 is a perspective view of a portion of the chainring.
Our design is a chainring characterized by a plurality of teeth formed about the periphery thereof. Shading and/or dashed lines are not features or part of the design, but are used to illustrate surface contours or environment in the drawings. The broken lines shown in the drawings illustrate environmental structure and portions of the chainring that forms no part of the claimed design.
