A collapsible towing hitch includes a base member which is pivotally mounted to the front bumper or frame or a vehicle so as to rotate from an operable position to a storage position. A pair of spring-loaded latch pins are mounted on the base member and correspond with apertures in a pair of yoke brackets and in a pair of base member mounting brackets so as to selectively lock the base member in the storage position. A pivotal arm is mounted at each end of the base member to pivot in a generally horizontal plane when the base member is in the operating position. An elongated bar is pivotally connected to the free end of each pivotal arm, and each bar is mounted at its free end to a ball hitch housing. The pivotal connection between the elongated bars and the pivotal arms may be selectively locked in an aligned condition utilizing a pin mounted through a pair of apertures in the pivotal arms and elongated bars. In this fashion, the pins may be removed so as to pivot the pivotal arms with respect to the elongated bars and collapse the ball hitch housing into close contact with the base member. Once the ball hitch housing is collapsed against the base member, the base member is rotated and locked in an upright position for storage, such that the vehicle may be utilized in a conventional manner.

A collapsible towing hitch, comprising: mounting means attachable to a vehicle to be towed; a base member pivotally mounted on said mounting means, for movement about a generally horizontal axis transverse to the direction of towing, said base member being pivotable between a storage position and a towing position, and said base member having first and second ends; means on said base member for selectively locking said base member in the storage position; a first arm member pivotally connected at a first end to said first end of said base member; a second arm member pivotally connected at a first end to said second end of said base member; said first and second arm members being pivotal within the same plane; a first elongated bar member pivotally connected at a first end to the second end of said first arm member; first hinge means pivotally connecting said first elongated bar member to said first arm member; said first hinge means comprising: a pair of parallel and spaced apart hinge plates affixed to and extending from the first end of said first bar member, each of said hinge plates having a first aperture formed therein; a hinge collar mounted on the second end of said first arm member; and a hinge pin journalled through said first apertures and said hinge collar to pivotably connect said first arm member to said first bar member; means connected to said first arm member for selectively locking said first arm member and first bar member in axial alignment, comprising: said first arm member having a hole therethrough adjacent to said second end; each of said hinge plates of said first hinge means having a second aperture formed therein, said second apertures being coaxially aligned and adapted to register with said hole when said first bar member is axially aligned with said first arm member; and a locking pin selectively journalled through said second apertures and said hole when said first bar member is axially aligned with said first arm member to thereby selectively lock said first arm member and said first bar member in axial alignment; a second elongated bar member pivotally connected at a first end to the second end of said second arm member for pivotal movement in the same plane as said second arm member; second hinge means pivotally connecting said second elongated bar member to said second arm member; said second hinge means comprising: a pair of parallel and spaced apart hinge plates affixed to and extending from the first end of second bar member, each of said hinge plates having a first aperture formed therein; a hinge collar mounted to the second end of said second arm member; and a hinge pin journalled through said first apertures and said hinge collar to pivotably connect said second arm member to said second bar member; means connected to said second arm member for selectively locking said second arm member and second bar member in axial alignment, comprising: said second arm member having a hole therethrough adjacent to said second end; each of said hinge plates of said second hinge means having a second aperture formed therein, said second apertures being coaxially aligned and adapted to register with said hole when said second bar member is axially aligned with said second arm member; and a locking pin selectively journalled through said second aperture and said hole when said second bar member is axially aligned with said second arm member to thereby selectively lock said second arm member and said second bar member in axial alignment; hitch mounting means pivotally connected between the second ends of said bar members, for operably mounting said collapsible towing hitch to a towing vehicle; and said hitch mounting means being selectively movable between an extended towing position, wherein said first arm and first bar and said second arm and second bar are locked in aligned orientation with said hitch mounting means spaced away from said base member, and a collapsed storage position, wherein said first arm and first bar and said second arm and second bar are pivoted with respect to each other so as to be generally parallel and with said hitch mounting means in close proximity to said base member.
