DETAILED DESCRIPTION

(13) Reference is now made to FIGS. 1, 1a, 2a and 2b, illustrating a first embodiment of retention device or retractable charge cord retainer 10 useful in a charge cord management arrangement 12 illustrated in FIG. 3.

(14) As best illustrated in FIG. 1, the retractable charge cord retainer 10 includes a base 14 and a plunger 16 displaceable with respect to the base between a home position (illustrated in FIG. 2a) and a deployed position (illustrated in FIG. 2b). The plunger 16 includes a head 46.

(15) A biasing element 18 is received and held in the base 14 and adapted to bias the plunger 16 toward the deployed position. More specifically, in the illustrated embodiment, the biasing element 18 comprises a compression spring received concentrically around the inset end 19 of the plunger 16. One end of the biasing element 18 presses against the closed end 32 of the base 14, the other end presses against the shoulder 21 of the plunger 16.

(16) As further illustrated in FIGS. 1, 1a, 2a and 2b, the retractable charge cord retainer 10 includes a guide feature, generally designated by reference numeral 20. The guide feature 20 includes a guide track 22 and a guide follower 24. More specifically, the guide track 22 is carried on the inner wall 26 of the base 14. The guide feature 20 also includes a channel 28 in the plunger 16. In the illustrated embodiment, the guide follower 24 is a ball that is received in both the guide track 22 and the channel 28.

(17) In the illustrated embodiment, the channel 28 is continuous, extending circumferentially around the plunger 16. Further, the guide track 22 is a zigzag groove extending continuously around the inner wall 26 of the base 14. The zigzag grooved guide track 22 includes a first vertex 30 oriented toward a closed end 32 of the base 14 and a second vertex 34 oriented toward an open end 36 of the base 14.

(18) When the plunger 16 is in the home position (illustrated in FIG. 2a), retracted into the base 14, the guide follower 24 is positioned in the first vertex 30 of the guide track 22 oriented toward the closed end 32 of the base. In contrast, when the plunger 16 is in the deployed position (illustrated in FIG. 2b), extending from the base 14, the guide follower 24 is received in the second vertex 34 of the guide track 22 oriented toward the opened end 36 of the base 14.

(19) When the plunger 16 is in the first position illustrated in FIG. 2a, one depresses the head 46 of the plunger 16 in the direction of action arrow A against the force of the biasing element 18. Upon releasing the plunger 16, the biasing element biases the plunger 16 to the deployed position illustrated in FIG. 2b. As this is done the guide follower 24 travels along the portion 38 of the guide track 22 extending between the first vertex 30 and the second vertex 34. When one wishes to return the plunger 16 to the home position, one again depresses the head 46 of the plunger in the direction of action arrow B against the force of the biasing element 18. This causes the plunger 16 to retract into the base 14 with the guide follower 24 travelling along the portion 40 of the guide track from the second vertex 34 to the first vertex 30. Upon release, the engagement of the guide follower 24 in the first vertex 30 functions to maintain the plunger 16 in the home position.

(20) Reference is now made to FIG. 3 illustrating the charge cord management arrangement 12. That charge cord management arrangement 12 comprises a retractable charge cord retainer 10, of the type illustrated in FIGS. 1, 2a and 2b, mounted to the side 42 of the center console 44. When the retractable charge cord retainer 10 is adjusted by the operator to be in the deployed position illustrated in FIG. 3, the head 46 of the plunger 16 projects from the side 42 of the center console 44. This allows one to wrap a charge cord 50, for powering the smart phone 52, partially around the plunger 16 behind the head 46 where that charge cord is maintained out of the way of the gear shift 54 and the radio controls 56 so as not to be an annoyance or distraction to the motor vehicle operator. When not in use, the plunger 16 may be returned to the home position where the head 46 of the plunger may seat substantially flush with the side 42 of the center console 44.

(21) The retention device or retractable charge cord retainer 10 illustrated in FIGS. 1, 2a, 2b and 3 is useful in a method of managing a charge cord. That method includes the steps of deploying the retractable charge cord retainer 10 and wrapping the charge cord 50 at least partially around the plunger 16 of the retractable charge cord retainer following deployment.

(22) The deploying of the retractable charge cord retainer 10 includes steps of depressing a head 46 of the plunger 16, releasing the head and waiting for the stem 47 of the plunger behind the head to project from the base 14 of the retractable charge cord retainer. In addition the method may further include the step of at least partially wrapping the charge cord 50 on the plunger 16 around the stem 47 behind the head 46. (See FIG. 3.)

(23) Reference is now made to FIGS. 4, 5a, 5b, 6, 7a and 7b illustrating a second embodiment of retention device 100 which includes a housing 102, a retainer 104 and an actuator 106. The retainer 104 includes a pivot, in the form of a pivot pin 108, that pivotally connects the retainer to the housing 102 allowing the retainer to be displaceable between a stowed position illustrated in FIGS. 4, 5a and 5b, and a use position illustrated in FIG. 6.

(24) In the illustrated embodiment, the actuator 106 comprises a push button that is displaced from a first position illustrated in FIGS. 4, 5a, 5b and 7b to a second position illustrated in FIGS. 6 and 7a in order to displace the retainer 104 to the use position.

(25) More specifically, the housing 102 includes a first opening 110, and a second opening 112 separated by a partition 114. The retainer 104 is received in the first opening 110 while the actuator 106 is received in the second opening 112. In the illustrated embodiment, the first opening 110, the second opening 112 and the partition 114 are all provided on a front side 116 of the housing 102.

(26) A first biasing element 118 biases the retainer 104 toward the stowed position. A second biasing element 120 biases the actuator 106 toward the first position. In the illustrated embodiment, the first biasing element 118 comprises a coil spring having a first end 122 connected to the retainer 104 at the receiver 124 and a second end 126 connected to the partition 114 of the housing 102 at the receiver 128. In the illustrated embodiment, the second biasing element 120 is a compression spring having a third end 130 connected to the actuator 106 at the receiving well 132 and a fourth end 134 connected to the rear wall 136 of the housing 102 by a concentric pin or receiver well (hidden from view).

(27) As should be appreciated from viewing FIGS. 5a and 6, the housing 102 also includes a guideway, generally designated by reference numeral 138. The guideway 138 is defined between the partition 114, the two sidewalls 140, 142 of the housing and the bottom wall 144 of the housing. The actuator 106 is displaced and translated along the guideway 138 between the first position and the second position.

(28) As best illustrated in FIGS. 5a and 5b, the actuator 106 includes a cam surface 146 and the retainer 104 includes at least one cam follower 148. More specifically, in the illustrated embodiment, the cam surface 146 includes an arcuate section 150 and a step 152 at one end thereof. The cam follower 148 comprises two curved projecting tabs 154 with rounded ends 156 that engage and slide along the cam surface 146. As should be appreciated from viewing FIGS. 5a and 6, the cam follower 148 engages and follows the cam surface 146 as the actuator 106 is displaced between the first and second positions as illustrated in those figures.

(29) In the illustrated embodiment, a stop 158 is carried on the actuator 106. That stop 158 functions to retain the actuator 106 in the housing 102 by engaging the front side 116 of the housing when the actuator is pressed forward by the second biasing element 120.

(30) In the illustrated embodiment, the retainer 104 includes a retention tab 160 that functions to retain a charge cable C in the deployed retainer 104 in a manner that will be described in greater detail below. The retention tab 160 and the tabs 154 of the cam follower 148 project from the inner face 162 of the retainer 104.

(31) The retention device 100 is useful in a method of retaining a charge cord C. That method comprises depressing the actuator 106 in the direction of action arrow D against the force of the first biasing element 118. When the actuator 106 is depressed, the cam follower 148 of the retainer 104 slides along the arcuate section 150 to the step 152 of the cam surface 146 of the actuator 106 (compare FIGS. 5a and 6). This causes the retainer 104 to pivot about the pivot pin 108 from the stowed position illustrated in FIG. 4 to the use position illustrated in FIG. 6.

(32) This is then followed by the step of inserting the charge cord C into the retainer 104. Upon releasing the actuator 106, the second biasing element 120 biases the actuator 106 toward the home or first position illustrated in FIG. 4. This frees the first biasing element 118 to bias the retainer 104 about the pivot pin 108 back toward the stowed position. As a result, the charge cord C is retained in the retainer 104 by the positive force provided by the first biasing element that squeezes the charge cord between the retainer and the housing 102. The retention tab 160 slightly laps the top of the charge cord to ensure proper retention.

(33) When one desires, one may release the charge cord C from the retainer 104 by pulling the charge cord against the biasing force of the first biasing element 118 so as to open the retainer 104 slightly and thereby allow removal of the charge cord. Once removed, the first biasing element biases the retainer 104 back to the stowed position illustrated in FIG. 4.

(34) FIG. 7a illustrates a center console 164 incorporating two retention devices 100 with the retainers 104 deployed in the use position and holding a charge cord C away from the gear shift 166. In this position, the charge cord C will not interfere with operator control of the various motor vehicle systems thereby virtually eliminating the potential distraction and annoyance of the charge cord. FIG. 7b illustrates the same two retention devices 100 in the center console 164 when they are not in use for holding a charge cord. As should be appreciated, the front face of the retainer 104 and the front face of the actuator 106 fit substantially flush with the front face or side 116 of the housing 102 which fits substantially flush with the sidewall of the center console 164. Thus a flush clean appearance is maintained.

(35) The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
