Bicycle trailer hitch

Abstract

A bicycle trailer hitch which attaches to the bicycle between the chain stay and the seat stay at the crotch formed at the convergence of the two stays, the method of attachment being by three attaching members affixed to and extending inward from a main hitch member to which the bicycle trailer is connected. The three attaching members include a cone-plate member, wherein the intersection of a cone and a plate form a notch which engages the crotch between the two stays; a fixed finger located beneath the chain stay, and a movable finger located above the seat stay. Movement of the movable finger towards the seat stay is accomplished a pivoting member and a threaded tightening member, each attached pivotally at one end to the main hitch member, wherein the non-attached, threaded end of the tightening member passes through an aperture in the pivoting member so that rotation of a threaded knob engaged to the tightening member past the pivoting member will cause the knob to press against the pivoting member. This pressure rotates the pivoting member, pressing the movable finger against the seat stay. Continued tightening of the knob also will cause pressure by the fixed finger against the chain stay and movement of the cone-plate member into notch abutment against the crotch, this combination of pressures by the three attaching members against the bicycle frame locking the bicycle trailer hitch securely to the bicycle.
