Abstract: A bicycle frame is disclosed wherein the down tube component comprises at least one aperture therein adapted for reception of an operating cable of the bicycle therein. The down tube is connected to the head tube and the bottom bracket of the frame, An open end portion of the down tube extends below the bracket so that cable threaded through the aperture may exit thereat below the bracket. A ferrule surrounds the aperture and helps to seal same from water which may otherwise penetrate into the tube.

Abstract: A one-piece extension arm for connecting a basketball backboard to a support pole including a central web portion, a pair of spaced legs, a pair of forward projections and a pair of rearward projections such that the extension arm is symmetrical about a plane that bisects and is perpendicular to the central web portion and a one-piece planar blank from which the extension arm is formed.

Abstract: A self-adjusting actuation mechanism is disclosed for use in a cable actuated system, such as a bicycle caliper brake system. The actuation mechanism includes a housing and a lever pivotally attached to the housing. A cable assembly is provided for operating an actuated mechanism and the cable assembly includes a sheath and a cable slidably positioned within the sheath and attached to the lever wherein actuation of the lever causes the cable to move in a first direction. An abutment member is supported within the housing in engagement with an end of the sheath and the abutment member is mounted for movement relative to the housing in a second direction opposite to the first direction in response to actuation of the lever whereby the effective length of the sheath is increased.

Abstract: A support assembly for supporting and orienting an elongated pole to extend at an angle to the vertical, wherein the support assembly includes a pole having spaced apart upper and lower ends, an intermediate point and a lower portion between the intermediate point and lower end. The support assembly also includes a base having a pivot axis, a point of pole engagement and an extension generally in the same direction as the angular extension of the pole when assembled on the base such that the pole and the base extension generally form two legs of an angle. The support assembly includes a support arm having spaced apart ends, wherein one of the ends engages the base in spaced relationship from the point of pole engagement on the base, and wherein an extension presents the other of the ends at the intermediate point on the pole when assembled so that the base extension, the support arm extension and the lower portion of the pole form a triangle.

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.
