Patent ID: 8596664

Claim:
An anti-rattle hitch configured to be received by a hitch receiver, the hitch comprising: a ball mount having an aperture; a tubular insert attached to the ball mount, the tubular insert having a longitudinal axis and sized to be slidably received by the hitch receiver, the tubular insert having a generally square shape comprising a first wall, a second wall, a third wall, and a fourth wall, wherein the first wall has a first piston aperture therethrough, and the second and fourth walls each include a locking pin aperture, wherein the locking pin apertures are configured to receive a locking pin; a first wedge member disposed inside the tubular insert and having a first surface slidably disposed adjacent the tubular insert third wall, and a first angled face opposite the first surface; a second wedge member having a first angled face that slidably engages the first wedge member first angled face; a first piston attached to the second wedge member and extending through the first piston aperture such that the longitudinal position of the second wedge member within the tubular insert is fixed; an adjustment member comprising a bolt having a threaded portion that threadably engages the first wedge member and a head that extends out of the tubular insert and that extends through the aperture in the ball mount and threadably engages the first wedge member, wherein the adjustment member is operable to slidably adjust the longitudinal position of the first wedge member; and a biasing member that biases the first wedge member away from the head of the adjustment member; wherein slidably adjusting the first wedge member in one direction will urge the second wedge member outwardly such that the first piston moves outwardly away from the first wall, such that the first piston presses against the hitch receiver to thereby reduce or eliminate play between the hitch and the hitch receiver.
