초록 ▼

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.

A bicycle trailer hitch for connecting a bicycle trailer to a bicycle, wherein the bicycle trailer has a trailer tongue, and the bicycle has on each side, for support of a rear axle and wheel, a first frame member and a second frame member which converge at an angle adjacently ahead of the rear axle, the convergence forming a crotch between said two frame members; the bicycle trailer hitch comprising: a. a main hitch member, having a front, a rear, an outer side positioned away from the bicycle, and an inner side positioned toward the bicycle; b. a crotch engaging member, attached to the rear inner side of the main hitch member and extending inwards towards the bicycle so as to be positioned within the crotch between the first frame member and the second frame members, whereat it engages said crotch; c. a fixed positioning member located on the inner side of the main hitch member forward of the crotch engaging member, and extending inwards towards the bicycle so as to be located adjacent to the first frame member outside of the angle formed by the first and second frame members; d. a movable positioning member, attached to the main hitch member and extending inwards toward the bicycle so as also to be located adjacent to the second frame member outside of the angle formed by the first and second frame members; e. means for causing movement of said movable positioning member toward the inside of the angle formed by the first and second frame members; f. wherein said movement of the movable positioning member, the movable positioning member being located outside of the second frame member, will cause the movable positioning member to press against the outside of the second frame member, will cause the fixed positioning member to press against the outside of the first frame member and in addition will cause the crotch engaging member to press against the crotch between the two frame members, which combination of pressures serve to securely lock the main hitch member against the crotch between the two frame members, and thereby attach the bicycle trailer hitch to the bicycle; and g. means for connecting the trailer tongue to the main hitch member.
