the present invention generally relates , but is not limited , to a nail polish display system configured to rotate or otherwise agitate bottles of nail polish to maintain the polish in a sufficiently mixed state . in at least one embodiment , the nail polish display system includes a display case with agitators that hold one or more bottles of nail polish . the agitators and bottles may be arranged in a variety of configurations . a programmable motor may be used to drive the agitators , which may take the form of rotating members driven at a desired angular velocity . coupling assemblies attached to the agitators may either support or clasp to the bottles . in one embodiment , the display case includes a touch or proximity sensor that signals the motor to stop when someone opens a door of the case , reaches inside the case , or makes some other detectable action to indicate that they want to handle one of the bottles of finger nail polish . upon receiving such a signal either from the sensor or by way of a remote control , the motor may be commanded to move the agitators and thus position the bottles in a desired orientation , for example position the bottles oriented cap side up . fig1 shows a nail polish display system 100 for a plurality of bottles 102 , each preferably containing a different color of nail polish ( not shown ). each bottle 102 includes a polish - holding portion 104 and a cap portion 106 , the latter typically being threaded onto the polish - holding portion 104 . the bottle 102 may also include a neck portion 108 . the bottles 102 are located generally within a case 110 , which may have a transparent door 112 hingedly 114 attached to the case 110 according to one embodiment . a handle 116 may be coupled to the door 112 or the door may be spring and / or magnetically actuated to open and shut by pressing on the door 102 . a sensor 117 may be located on a front of the case 110 . the sensor 117 may take the form of a touch sensor , a proximity sensor or some other device capable of detecting the presence of a person in front of the case 110 . an agitator 118 coupled the case 110 may take the form of a rotatable rod attached to bottle - coupling assemblies 120 . in the illustrated embodiment , the agitators 118 include a drive arm 122 , an offset arm 124 and a bottle - support portion 126 . fig2 shows a top , plan view of the bottles 102 arranged in a lower row 128 of the case 110 of fig1 , but with the case structure removed for purposes of clarity . fig3 and 4 show the bottle - coupling assembly 120 according to an embodiment of the present invention . the assembly 120 includes a base member 130 connectable to a sleeve member 132 . the base member 130 is fixed to the agitator 118 . in the illustrated embodiment , the sleeve member 132 is configured to closely receive the bottle 102 . the sleeve member 132 may include an elastomeric , foam or synthetic liner , insert or seal 133 that suctions to the bottle 102 . in addition , the sleeve member 132 may include a magnetic plug 134 preferably embedded into the sleeve member 132 . alternatively , the sleeve member 132 itself may be made from an iron - based substance and thus be magnetizable . similarly , the base member 130 may also be made from a magnetizable material or include a magnetizable plug ( not shown ). in use , an interested person would select and remove a bottle 102 from the case 110 and the sleeve member 132 would stay attached to the bottle 102 . the person could examine the bottle 102 ; sample its contents , etc . upon placing the bottle 102 back in the case 110 , the magnetic attraction between the base member 130 and sleeve member 132 would urge the bottle 102 back into place on the agitator 118 . fig5 shows another display system 200 having bottles 202 arranged in a case 204 . the display system 200 may include many of the same aspects of the display system 100 as described above , but these same or similar components are not described in detail herein for purposes of brevity and may not be illustrated for purposes of clarity . in the illustrated embodiment , the system 200 includes agitators 206 and bottle - coupling assemblies 208 . as best shown in fig6 , each bottle - coupling assembly 208 includes a spine member 210 coupled to bottle support members 212 and a leverage member 214 , which in turn may be coupled to a base member 216 . the bottle support members 212 are configured to closely receive the polish - holding and cap portions , respectively . moreover , at least one of the bottle support members 212 may provide a clamping action on the bottle 202 . the leverage member 214 may be welded , bonded or otherwise attached to the base member 216 . fig7 and 8 show yet another display system 300 having bottles 302 arranged in a case 304 . the display system 300 may include many of the same aspects of the display system 100 as described above , but these same or similar components are not described in detail herein for purposes of brevity and may not be illustrated for purposes of clarity . in the illustrated embodiment , the system 300 includes agitators 306 and bottle - coupling assemblies 308 . as best shown in fig8 , each bottle - coupling assembly 308 includes a spine member 310 coupled to a bottle support member 312 and to end - cap members 314 , 316 ( top and bottom , respectively ). the bottle support member 312 is configured to closely receive the polish - holding , neck or cap portion of the bottle 302 . the spine member 310 , bottle support member 312 , and end - cap members 314 , 316 may take the form of a one - piece component or may be attached together by welding , bonding or some other mechanical process . fig9 shows yet another display system 400 . in the illustrated embodiment , bottles 402 are arranged on a plurality of tiered surfaces 404 . the bottles 402 are held by coupling members 406 , which in turn are actuated by agitators ( not shown ). to mix the polish in the bottles 402 , the surfaces 404 may be telescoped such that they may be lowered and then the bottles rotated in either a clockwise or counterclockwise direction . a motor ( not shown ) for moving the agitators may also be coupled to a gearbox that moves the surfaces 404 . the cases described above may take a variety of forms and shapes , they may be wall mounted or placed on a surface , such as a countertop , desk or floor . the cases may be made out of virtually any material , for example , wood , plastic , metal , etc . in one embodiment , a backing for the case may be a mirrored surface for aesthetic reasons . while the cases may have doors , such doors may take a variety of forms such as hinged doors , sliding doors , etc . a light source such as a light bulb or light emitting diode may be located within the case to provide a desired amount of lighting . fig1 shows yet another display system 500 in which bottles 502 are coupled to individual cases 504 . in turn , the cases 504 may be rotated with the bottles 502 fixed thereto or the bottles 502 may be rotated within each static case 504 . the bottles 502 are coupled to the cases 504 using attachment rods 506 in cooperation with coupling devices 508 . the shapes and arrangement of the cases 504 may take many forms . further , the rods 506 may be removable and replaceable and / or interchangeable with different styles , shapes , contours , etc . fig1 shows a block diagram 600 of a display system 602 . as described above , the display system 602 includes some form of a case with bottles of finger nail polish . by way of example , each bottle is coupled to a rotating member 604 , which is moved through operation of a motor 606 . optionally , a gearbox 608 or equivalent mechanism may be employed to reduce , increase or otherwise modify the speed of the rotating member 604 . an optical sensor 610 may be positioned to detect a rotational position of the rotating member 604 and this positional information communicated to a controller or microprocessor 612 . by knowing the rotational position of the rotating member 604 , the motor may be controlled to move the bottles into a desired position and / or orientation when a touch sensor 614 is triggered by a patron or employee . for example and briefly referring to fig1 and 11 , a patron may trigger the touch sensor 117 / 614 , which in turns provides a signal to the controller / processor 612 . the optical sensor 610 correspondingly provides the rotational position of the rotating members 604 to the controller 612 , which in turn commands the motor 606 to move the bottles into an upright position for removal by the patron . alternatively , the case may be maintained in a locked configuration inaccessible by a patron until an employee commands the case to open using a remote control device 616 . so if a patron wants to sample a bottle of nail polish , the employee sends a signal using the remote 616 , which opens the case , provides a signal to the controller 612 , and consequently operates the motor 606 to move the rotating members 604 into the desired position and / or orientation . in one embodiment , the rotating members 604 may be configured to make the bottles continue to rock slowly rather than come to a complete stop after the touch sensor 614 is triggered . fig1 shows a block diagram 700 of a display system 702 . like components already described , specifically the rotating member 704 , the optional gearbox 708 , and the remote control device 716 , are not be re - described herein . the system 702 includes a proximity sensor 714 to detect a presence of a person near the system 702 , for example the presence of a patron ready to open a door on the display case . the proximity sensor 714 may take a variety of forms and may be located in a variety of places on the case . the rotational speed and position of the rotating member 704 is controlled by a motor 706 having motor control logic 712 in cooperation with a position sensor 713 . the position sensor 713 determines a rotational position of a motor shaft or some other motor component and then provides this rotational position information to the control logic 712 . in one embodiment , the motor 706 takes the form of a stepper motor and operates to quickly rotate the rotating member 704 either clockwise or counterclockwise to position the bottles in the desired position and / or orientation relative to the case . the inclusion of the motor and controller or control logic permits the bottles to be positioned and oriented in a manner that makes them aesthetically pleasing and readily accessible . the motor may be programmable to modify the agitation speed of the bottles , the rotational direction , etc . the remote can be used to stop the rotation of the bottles from a distance . alternatively , a sensor may be positioned on the case to detect movement by an interested patron . upon sensing such movement , the sensor communicates with the controller or control logic , which in turn instructs the motor to stop rotating the bottles so the patron may view and possibly remove the nail polish bottles when they are in an upright position . to prevent the patron from waiting too long , the motor may be commanded to accelerate in the same or reverse direction to orient the bottles within milliseconds of the movement detected by the sensor . in another embodiment , the controller or control logic may include a timing module that instructs the motor to restart after a set period of time . the set period of time may be a certain time after the door to the case has been closed , in which such closure may be detected by a contact sensor , or a certain time after no more movement is detected by the proximity sensor on the case . while the illustrated embodiments show cases with multiple bottles and rotating members , it is appreciated that the invention may be a case configured to hold and agitate a single bottle . such a case may be advantageous at a technician &# 39 ; s work station or by individuals in their home . while the technician or individual is preparing nails for painting , they can place the nail polish bottle into the case and then allow the bottle to be agitated for an adequate amount of time to sufficiently mix up the polish . once the polish is mixed , the bottle will stop agitating and the technician / individual will know the polish is now ready for use . while the preferred embodiments of the invention have been illustrated and described , as noted above , many changes can be made without departing from the spirit and scope of the invention . accordingly , the scope of the invention is not limited by the disclosure of the preferred embodiments . instead , the invention should be determined entirely by reference to the claims that follow .
