Abstract: An articulated roller assembly for a bent bar comprising an articulated roller configured to spin relative to the bent bar. The bent bar generally comprises at least one bent portion and at least one straight portion. The articulated roller is designed to be fitted over the bent portion of the bar to be positioned on the at least one straight portion of the bar where it spins freely. The articulated rollers comprise a series of cylindrical rigid bushings surrounded by a flexible, deformable sleeve. The bushings have an inner diameter and length such that the articulated roller can be fitted over the bent portion of the bar. In some examples, the inner diameter and length of the bushings are a function of the outer diameter of the bent bar and the radius of the bend in the bent portion of the bar.

Abstract: A storage rack is formed by a plurality of stacked modules where each module includes a vertical support column and a support arm that extends outwardly and downwardly from the vertical support column at an angle of about thirty degrees. A barrier arm is pivotally mounted to a distal free end of the support arm. A strap extends from a first, inner end of the support arm to the barrier arm. Elongate objects placed atop the strap cause the barrier arm to pivot into a vertical position to create a barrier that prevents objects from rolling or sliding in a direction away from the vertical support column. When the elongate object is lifted from the support arm, the tension in the strap is released and the barrier arm pivots into a horizontal position of repose to facilitate removal of the object from the support arms.
