Abstract
An integral hose anti-collapse rib comprises a unitary body having a first cantilevered portion curved in a first direction. This first cantilevered portion defines a first end. A second cantilevered portion is curved in a direction opposite the direction of the first cantilevered portion, in a direction facing the first cantilevered portion. The second cantilevered portion also defines a second end disposed at an opposite extent of the rib from the first end. The hose anti-collapse rib also comprises a locking mechanism that locks the first end of the rib to the second end of the rib, such that the first and second cantilevered portions together form a generally circular shape. Embodiments of locking mechanisms may include a button and orifice locking mechanism and/or a tab and channel locking mechanism. In a relaxed state in which the locking mechanism is not engaged, the rib preferably defines a non-circular, generally spiral shape.
