Abstract: A latch assembly includes a buckle and a tongue for releasably engaging the buckle. The tongue has a cut-out. The buckle includes a base having a slot for receiving the tongue. The buckle also includes a locking pawl pivotally attached to the base and engageable by the tongue, to pivot the locking pawl so that the locking pawl engages in the cutout of the tongue when the tongue is inserted in the slot of the base. The buckle also includes a release lever pivotally attached to the base, the release lever having a cut-out receiving the locking pawl to engage the release lever when the tongue is inserted in the slot of the base, thereby to block removal of the tongue from the buckle.

Abstract: A hub and wheel assembly for light load vehicle including baby carriages, infant strollers, wheelchairs and the like, the assembly having tandem wheels and a shock absorbing member in a trailing link suspension configuration. The assembly includes a wheel locking mechanism to lock one or both wheels into a secured position preventing the wheels from rolling about the axle. The wheel assembly incorporating a thrust bearing system to provide smooth and controlled swiveling relative to the vehicle body or frame and eliminates creeping and wobble. A swivel lock mechanism is also provided to allow the user to lock the tandem wheel assembly in a angular position relative to the vehicle body thereby preventing swiveling about the longitudinal axis of the swivel base housing. Each wheel is mounted to the axle in tandem using two low friction bearings and having a low-profile tire mounted to a rim with a reflective area for increasing safety in low elimination environments.
