DETAILED DESCRIPTION

(10) Reference is now made to FIGS. 1-3 illustrating a first embodiment of the cup holder retainer 10. The cup holder retainer 10 includes a support frame 12 and a preloaded retainer clip 14 which form a unitary body.

(11) As illustrated, the preloaded retainer clip 14 includes a first end 16 and a second end 18 defining a longitudinal axis. The preloaded retainer clip 14 is connected to the support frame by a living hinge 20 at the first end 16 and an integral biasing element 22 at the second end 18. As will become apparent in the following description, the living hinge 20 functions as a rotation axis for the preloaded retainer clip 14 with respect to the support frame 12 while the integral biasing element 22 functions to bias the preloaded retainer clip into a home or cup-engaging position.

(12) In one possible embodiment, the cup holder retainer 10 is molded from acetal homopolymer as a single piece or unitary body. This material provides the desired combination of creep resistance, flexural fatigue and impact strength to form the living hinge 20 and provide the desired resilience for the integral biasing element 22.

(13) As illustrated in FIGS. 1 and 2, the integral biasing element 22 may be formed or molded with an L-shape. As shown, the L-shaped integral biasing element 22 includes a first leg 24 and a second leg 26 wherein the first leg 24 is longer than the second leg 26. As illustrated, the distal end of the first leg 24 is connected to the support frame 12 while the distal end of the second leg 26 is connected to the preloaded retainer clip 14.

(14) Reference is now made to FIG. 3 illustrating the operation of the preloaded retainer clip 14. Under normal or static conditions, the integral biasing element 22 functions to bias the preloaded retainer clip 14 into the preloaded or home position illustrated in phantom line. However, when a cup is pushed downwardly in the direction of action arrow B across the beveled face 28 of the preloaded retainer clip 14, the retainer clip pivots or rotates about the living hinge 20 and is deflected outwardly in the direction of action arrow C through the cooperating aperture 30 formed in the support frame 12 toward the fully deflected or cup-receiving position illustrated in full line. As this occurs, the integral biasing element 22 is deformed from its normal L-shape. However, as the integral biasing element 22 remains connected between the first end 16 of the retainer clip 14 and the support frame 12 at the top of the aperture 30, the integral biasing element 22 functions to limit the pivot angle deflection of the retainer clip. The resilient memory of the material from which the cup holder retainer 10 is formed also results in the integral biasing element 22 seeking to return to its original L-shape, thereby biasing the preloaded retainer clip 14 to return in the direction of action arrow D back toward the home or phantom line position. Thus, the face 32 of the retainer clip is always biased inwardly into a cup-engaging position.

(15) Reference is now made to FIG. 4 illustrating an alternative embodiment of the cup holder retainer 10. The alternative embodiment of the cup holder retainer 10 illustrated in FIG. 4 essentially corresponds structurally to the embodiment illustrated in FIGS. 1-3 and, accordingly, like reference numbers are utilized to identify like components. The embodiment of the cup holder retainer 10 illustrated in FIG. 4 differs from that illustrated from the embodiment of FIGS. 1-3 by including additional integral biasing elements 40 that extend from a median edge 42 at each side of the preloaded retainer clip 14 to the support frame 12 at the side margins of the opening 30. Thus, as should be appreciated, this embodiment includes the integral biasing elements 22 and 40 at the first end 16 and median edges 42 of the cup holder retainer 14. Here it should be noted that the cup holder retainer 10 may assume the form of yet another embodiment having only integral biasing elements 40 on the median edges 42 of the retainer clip: that is, the integral biasing element 22 at the first end 16 is absent.

(16) Reference is now made to FIGS. 5 and 7 illustrating a cup holder assembly 50 having a cup holder body including two cup wells 52, 54. As illustrated, the cup wells 52, 54 are positioned downwardly and received within the support frame 60 of yet another embodiment of the cup holder retainer 10. In the illustrated embodiment, the cup holder retainer 10 includes a first preloaded retainer clip 62 connected to the support frame 60 by a first living hinge 64 and a first integral biasing element 66. The cup holder retainer 10 also includes a second preloaded retainer clip 68 spaced about 120 from the first clip 62 and connected by a second living hinge (hidden from view) and second integral biasing element 72 to the support frame 60. Together, the first and second retainer clips 62 and 68 extend through cooperating slots 58 in the sidewall 56 of the first cup well 52 and function together to positively hold any cup received in that cup well in the manner previously described.

(17) As further illustrated in FIGS. 5 and 7, the cup holder retainer 10 includes third and fourth preloaded retainer clips 74, 76 connected to the support frame by respective third and fourth living hinges (hidden from view) and third and fourth integral biasing elements 82, 84. The third and fourth retainer clips 74, 76 extend into the slots 58 in the sidewalls 56 of the second cup well 54 and function together to retain a cup in that cup well. FIG. 7 illustrates the cup holder assembly 50 in the center console 112 of a motor vehicle.

(18) Reference is now made to FIG. 6 illustrating yet another embodiment of the cup holder retainer 10. This embodiment of the cup holder retainer 10 includes a support frame 86 including a bottom wall 88 and three upstanding posts 90 oriented about 120 apart.

(19) The cup holder retainer 10 also includes first, second and third retaining clips 92 with one retaining clip received on each post 90. Each retaining clip 92 is connected to its associated post at the bottom end by a living hinge 94 (only two visible in the figure) and at the top by an integral biasing element 96.

(20) When a cup is pushed down into the cup holder retainer 10 illustrated in FIG. 6, the lower edge of the cup engages the beveled face 100 of the clips 92 and the clips are deflected outwardly against the biasing force of the integral biasing elements 96 into the apertures 98 of the posts 90. At all times, the integral biasing elements 96 function to bias the retaining clips 92 inwardly so that the gripping faces 102 of the clips 92 are preloaded toward a cup-engaging position thereby securely holding the cup in position.

(21) A method of producing a cup holder retainer 10 with an integral preload for gripping a cup is also described herein. That method includes the step of molding the cup holder retainer 10 with a unitary support frame 12 and retainer clip 14 wherein the retainer clip is connected to the support frame by a living hinge 20, forming a rotation axis for the retainer clip, and an integral biasing element 22 providing the preload. That molding may be completed using acetal homopolymer. Further, the method may include providing the living hinge 20 at a first end 16 of the retainer clip 14 and providing the integral biasing element 22 at the second, opposite end 18.

(22) In summary, the cup holder retainer 10 described herein is characterized by a number of distinct benefits and advantages. Any embodiment of the cup holder retainer 10 described herein may be simply and economically produced by molding from a single material such as acetal homopolymer. The resulting unitary body incorporates an integral biasing element 22, thereby eliminating the need for separate springs or elastic biasing elements commonly associated with cup holders of prior art design. This reduction in parts further reduces complexity and manufacturing costs while enhancing reliable operating performance over a long service life. Thus, the cup holder retainer 10 represents a significant advance in the art.
