Abstract
A chainguard is disclosed for fully enclosing a bicycle chain on a bicycle having a front sprocket and a rear sprocket. The chainguard includes inside and outside covers extending from the front sprocket to the rear sprocket. The inside cover is formed as a hinged structure having top and bottom halves which may be pivoted together once the inside cover is in position extending around the bicycle crank and the rear axle. After the inside cover is in position, the outside cover may be moved into engagement with the inside cover whereby the top and bottom halves of the inside cover are secured together and the bicycle chain is fully enclosed.

A chainguard for fully enclosing a bicycle chain on a bicycle having a front sprocket and a rear sprocket, said chainguard comprising:
- an inside cover having a top half and a bottom half for positioning adjacent to the front sprocket, said top half and bottom half extending from the front sprocket to a location adjacent to a back face of the rear sprocket and being movable toward each other to surround a crank housing adjacent to the front sprocket;
- and
- an outside cover for positioning adjacent to the front sprocket and extending to a location adjacent to a front face of the rear sprocket, said outside cover being movable into engagement with said top and bottom halves of said inside cover such that the bicycle chain is fully enclosed from the front sprocket to the rear sprocket.
A chainguard for fully enclosing a bicycle chain, said chainguard comprising:
- a top cover half;
- a bottom cover half;
- and
- an outside cover wherein said top and bottom cover halves are movable toward each other to form an inside cover surrounding a crank housing supporting a crank for actuating the bicycle chain, and said outside cover is movable relative to said inside cover into engagement with said inside cover to secure said top cover half and said bottom cover half in position relative to each other.
A chainguard for fully enclosing a bicycle chain on a bicycle having a front sprocket and a rear sprocket, said chainguard comprising:
- a front wall for extending in front of and adjacent to the front and rear sprockets, said front wall including means defining front and rear apertures for extending around a crank and a rear hub, respectively, of the bicycle;
- a back wall for extending behind and adjacent to the front and rear sprockets, said back wall including means defining front and rear apertures for extending around said crank and said rear hub, respectively, of the bicycle;
- edges extending around the periphery of said front and back walls to connect said front and back walls together and to fully enclose the bicycle chain and the front and rear sprockets;
- said back wall comprising a top half and a bottom half connected for pivotal movement relative to each other at a hinge located adjacent to a front edge of said back wall, said top and bottom halves defining upper and lower portions, respectively, of said front and rear apertures for said back wall;
- and
- wherein said edges include inner edges formed integrally with said back wall and outer edges formed integrally with said front wall for engaging said inner edges in interlocking engagement whereby said top and bottom halves of said back wall are secured in position relative to each other.
