A collapsible bicycle trailer includes a rigid chassis frame, hinged side rails, a side rail locking bar, a hinged tongue, and quick release wheels. The chassis frame has a generally rectangular-shaped outer frame member, and inner frame members spaced inwardly from and parallel to, the sides of the outer frame member, with wheels rotating between the outer and inner frame members. On each side of the chassis frame are positioned a pair of side rail hinge members to which are attached the lower ends of the side rails which rotate between an extended, vertical position and a folded horizontal position. The side rail hinge members also are designed to provide the connecting means between the outer and inner frame members. A side rail locking bar is pivotally attached to the top of one side rail and unfolds to securely connect to the top of the other side rail, forming a roll bar assembly. Extending forward from a front corner of the chassis frame is a tongue, having at its outer end a hitch for attaching the trailer to a bicycle. A pivot shaft is mounted between a side of the outer frame member and an inner frame member to pivotally support the inner end of the tongue, allowing the tongue to be folded 180-degrees to a position beneath and adjacent to the chassis frame. A U-shaped tongue clip, with securing pin penetrating its downwardly extending legs, is installed on the outer frame member to grasp and secure the trailer tongue in an open, extended position.

A collapsible bicycle trailer, comprising: a. a chassis frame, having a front, a rear and two sides, including: (1) a generally rectangular-shaped outer frame member; (2) two inner frame members, attached to the outer frame member, being inwardly located within the plane of the chassis frame and parallel to the two sides thereof; b. wheel axle mounts attached to the sides of the chassis frame so as to provide a location for the attachment of two wheels having a plane of rotation between the outer frame member and the inner frame members; c. two side rails, a first side rail and a second side rail, generally U-shaped; d. means for pivotally attaching the side rails to the chassis frame, to permit rotation of each side rail between a folded position substantially parallel to the chassis frame and an extended position substantially perpendicular to the chassis frame, which include a side rail hinge member having: (1) a base formed to attach to the chassis frame between the outer frame member and an end of an inner frame member, said base including: (a) a cylindrical extension sized to fit longitudinally within the end of said inner frame member; (b) an aperture, extending through said base of the side rail hinge member, said aperture being aligned with a corresponding aperture formed in said outer frame member; (c) so that a threaded fastening member, passing through said outer frame member aperture and said base aperture into a connector affixed within the inner frame member, secures said base of the side rail hinge member tightly against said outer frame member, thereby fixing the position of said base relative to the outer frame member and providing, by the cylindrical extension, a rigid protrusion upon which the inner frame member may be mounted; (2) a pivot member about which an end of a side rail is attached and rotates; and (3) a vertical stop which limits the upward extending rotation to a vertical position; e. means for retaining the side rails in the extended position; f. a tongue; and g. means for pivotally attaching the tongue to the chassis frame, to permit rotation of the tongue between a folded position, substantially parallel and adjacent to the chassis frame and an extended position to the front of the chassis frame.
