Patent ID: 8857827

Claim:
A manually propelled cart device, comprising: a platform frame; first and second non-direction biased caster wheels coupled to the platform frame towards a front thereof; third and fourth direction biased caster wheels coupled to the platform frame towards a rear thereof; a non-steering wheel coupled control frame extending upwardly from the platform frame and configured to be contacted by the hand of a user during use to steer and propel the cart; and wherein the control frame is coupled toward the rear of the platform frame proximate the direction biased wheels and ascends there above so that a user has ready leverage over the direction biased wheels to maneuver those wheels, and thereby the cart device, sideway; wherein the direction biased caster wheels have a sufficient turning range while under the bias that the cart device can roll primarily sideways relative to a straight forward line of travel, when moved in that direction via the control frame; and wherein at least one of the third and fourth direction biased caster wheels is direction biased due to a forward tilting of the caster wheel, and the forward tilting of the caster arrangement is at an angle in the range of 3 to 40 degrees.
