Abstract
A parking stand for supporting the tongue of a parked trailer. The parking stand has a coupling ball at its upper end for engagement in the socket of a coupling part on the front end of the trailer tongue and a castor wheel or fixed base at its lower end for supporting the stand on the ground. A clamp on the upper end of the stand acts against the trailer coupling part to secure the stand against swivel movement relative to the trailer tongue.
