A wheel lock and stand assembly for a trailer in which a swivel wheel lock locks the wheel against swiveling when the stand supports the trailer and unlocks the wheel when the stand is raised. A locking arm which is engageable with the swivel mechanism is mounted on a rotatable shaft, and a crank arm on the shaft is connected to the stand by a link. As the stand is lowered and raised, the link and the crank rotate the shaft to bring the locking arm into and out of engagement with the swivel mechanism. |
