Abstract: A gooseneck hitch assembly is provided for attaching to a towing vehicle. The hitch assembly generally includes a hitch ball head assembly and retaining assembly for receiving and securing the hitch ball head assembly. The retaining assembly includes a channel coupled to a locking collar. Once the hitch ball head assembly is inserted into the channel, the collar is released and resilient members guide the collar to its offset resting position to lock the hitch ball head assembly in place. Alternatively, the collar is released and resilient members guide a lever into a circumscribed groove of the hitch ball head assembly, thereby locking the hitch ball head assembly in place. The hitch ball head is removable and may be selectively received by the retaining assembly in both towing and inverted positions. Optionally, the hitch assembly may be protected or covered by a housing.

Abstract: A fifth-wheel hitch assembly is provided that converts a gooseneck hitch installed on a vehicle into a fifth-wheel hitch for receiving a kingpin. The hitch assembly generally includes a base assembly, a T-arm assembly for securing the gooseneck ball or gooseneck post of the installed gooseneck hitch, and a hitch head. The T-arm assembly includes a mechanism for pulling up on the gooseneck hitch, thus securing the base assembly against the vehicle bed.
