Abstract
Abstract A quick release trailer and hitch apparatus has a container mounted on a pair of wheels with a pair of pull bars attached for being adjacent to the outer front corner regions of the container. The pull bars being gradually and continuously together with their remote ends attached to a connecting member. The connecting member has a center gripping portion and a rigid attachment portion with an orifice therethrough. A swivel member, permanently coupled on a ball member and freely rotatable thereabout, has a hitch portion with a first passageway for receiving the rigid attachment portion and a second passageway intersecting the first passageway. A spring loaded pin is provided to extend through the second passageway and the orifice in the rigid attachment portion to hold the swivel member and the connecting member immovable relative to each other. The ball member is attached to the bicycle in any appropriate way, such as with a bracket.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
331 words
A quick release hitch assembly for releasably coupling a trailer to a vehicle comprising: a coupling member having an upstanding post and a spherical ball portion attached to the top of the upstanding post, the coupling member being attached to the vehicle; a swivel member having a socket portion for permanently mounting the swivel member essentially on the ball portion, the swivel member having a ball receiving socket therein, slightly less than half of the sphere of the ball portion being positioned in the ball receiving socket, the swivel member further having a retention disc with a central orifice having an interior chamfered edge, the central orifice of the retention disc having a diameter less than the diameter of the ball member, the ball member being loosely retained in the ball receiving socket by the retention disc when the retention disc is attached to the swivel member about the peripheral edge of the ball receiving socket whereby the swivel member is freely movable about the ball portion, the swivel member further having a hitch portion having a swivel member end surface, a first closed-ended, substantially straight, passageway extending from the swivel member end surface into the hitch portion, and a second open-ended passageway therethrough intersecting the first passageway; a connecting member permanently attached to the trailer and having a connecting member shoulder and an attachment portion extending from the connecting member shoulder for being releasably inserted into the first passageway, the attachment portion having an attachment orifice therethrough, the attachment orifice being positioned so that it will be aligned with the second passageway when the attachment portion is inserted in the first passageway and the swivel member end surface abuts against the connecting member shoulder; and a pin for being removably inserted through the second passageway and the attachment orifice for essentially coupling the connecting member to the swivel member, the connecting member being released from the swivel member by removing the pin from the second passageway and the attachment orifice.

Claim 3
Dependent Claim
104 words
The hitch assembly of claim 1 wherein the connecting member further comprises a trailer deflection means interconnected to the trailer wherein the deflection means comprises: A pair of pull bars interconnected between the attachment portion and the trailer on opposite sides thereof, the spacing of the pull bars at a front location of the trailer nearest the attachment portion being about the same as the width of the trailer at the front location, the spacing between the pull bars continuously and gradually decreasing in the direction of the attachment portion whereby the trailer is deflected away from a stationary object by the pull bars.
Claim 4
Dependent Claim
97 words
The hitch assembly of claim 2 wherein the connecting member further comprises gripping means between the attachment portion and the pair of pull bars for hand-pulling the trailer assembly when the trailer is disconnected from the hitch portion of the swivel member and the cross-section of the first passageway and the cross-section of the connecting member attachment portion are oval wherein the shape of the cross-section of the attachment portion is substantially the same as the shape of the cross-section of the first passageway for allowing the attachment portion to be releasably inserted in the first passageway.
