<p>The present invention is directed to a tip-resisting caster which is adapted to provide tip resistance for a barbecue grill when tip tested for compliance with Canadian Standards Agency standard no. 1.6, Section 2.18.4 The preferred caster of the present invention comprises a chassis, a connector such as a flange or a post, at least one wheel, and a kickstand or the like. The connector depends upwardly from the chassis, thereby defining a longitudinal axis for the caster, and is operable for attachment to an object desired to be rolled. There are preferably two wheels which are connected to the chassis about a rotational axis, whereby the rotational axis is generally transverse to the longitudinal axis and is offset from the longitudinal axis towards a rear side of the caster. Due to the offset between the rotational axis and the longitudinal axis, the wheels are biased towards a rear side of the caster. The kickstand is rigidly attached to the caster and projects from the caster towards a front side of the caster, whereby a line drawn tangent with both the wheel and the kickstand is offset from the longitudinal axis by at least 75°. In this manner, the kickstand is adapted to contact a horizontal surface when the barbecue grill is inclined to 15°.</p> |
