Abstract
A fastener assembly is disclosed for connecting an attachment to a frame. The fastener assembly is mounted to a frame portion of, for example, a garden-type tractor. The fastener includes a pin holder, latch pin, and torsion spring. The torsion spring includes two leg portions and a coil portion which is between and integral with the leg portions. The torsional spring secures the latch pin to the pin holder, and it is in constant tension when the latch pin is engaged and disengaged. The attachment is connected to the frame by aligning an opening in the attachment with the latch pin and pushing the latch pin to engage or pulling the latch pin to disengage. When the latch pin is disengaged, the spring coil is compressed and applies an outward force to keep the pin disengaged, and when the latch pin is pushed towards its engaged position, the spring coil resists until it snaps over-center and then it urges the latch pin into locking engagement.
