<p>The opening (233) between two adjustable arms (204-205) can be varied to accommodate a wide variety of beverage container sizes. A swivel bar (203) is pivotally attached to a supporting structure (202) by inserting hinge pins (210) into hinge pin holes (212). A pair of arms, each of which includes a retaining pin (214), are pivotally attached to the swivel bar by inserting the retaining pins into holes (218) at opposite ends of the swivel bar. The retaining pins have a narrow stem (214a) and a wider head (214b), the head being wider than the holes. During assembly, the head compresses as it is being inserted into the hole, and expands after it has been forced through the hole, thereby permanently attaching the arm. A detent wheel (213), cantilever spring (215) and pawl (216) hold the arms in one of three predetermined angular positions. Each arm, detent wheel and retaining pin are integrally formed as a unitary structure from a single plastic injection mold. Similarly, the swivel bar, spring and pawl are integrally formed from one mold. Alternately, the arm may include an insert (603) that can be positioned in one of three insert holes (504a-504c) in the swivel bar. To adjust an arm, the swivel bar/arm assembly must be tilted to a 45° 'adjustment' position, and then the arm is lifted so that the insert can be repositioned in a different hole.</p> |
