     BACKGROUND OF THE INVENTION 
       [0002]    Field of the Invention 
         [0003]    The embodiments of the invention relate docking stations for electronic devices, and more particularly, to a horizontal docking station for a laptop computer. Although embodiments of the invention are suitable for a wide scope of applications, it is particularly suitable for a drivetrain for a motorized horizontal docking station. 
         [0004]    Discussion of the Related Art 
         [0005]    The related art docking stations include docking stations for laptop computers. Docking stations of the related art are generally of the form disclosed in U.S. Pat. No. 6,309,230 to Helot, particularly  FIG. 1  and  FIG. 2 . The related art docking stations generally interface with an electronic device such as a laptop computer. The electrical connection between electronic device and docking station is generally achieved through a single, multi-pin docking port. The related art docking station generally provides a multitude of additional interface ports connected to the docking port. 
         [0006]    Docking stations of the related art also include multi-plug to multi-port docking stations such as disclosed in U.S. Pat. Pub. 2013/0148289 of Kitae Kwon (“Kwon”), particularly in FIG. 2 (multi-plug), and FIG. 6 (multi-port). See also U.S. Pat. Pub. 2012/0127651 of Kitae Kwon, et. al. Kwon discloses, generally, a plurality of plugs on a sliding arm that can be activated by a lever. When the lever is activated, the arms squeeze together and engage the plurality of plugs with the corresponding ports of an electronic device. Kwon also discloses using a Kensington-style lock to bind the sliding arm to the chassis and prevent movement sliding arm. 
         [0007]    Docking stations of the related art also include motorized docking stations such as disclosed in U.S. patent application Ser. No. 14/306,198 of Vroom. Vroom discloses, generally, a docking station actuated by a motor connected to rack-and-pinion arms (See Vroom, FIG. 16). The arms are connected to sliders on underside of the tray (See Vroom, FIG. 19). A motor turns the pinion gear which moves a rack-gear portion of the arms to actuate connector blocks. 
         [0008]    The related art docking stations also include opposing connector blocks. To connect a computer to the related art docking stations, a user positions the electronic device within the docking station, and activates a lever to cause the opposing connector blocks to press into the electronic device thereby making an electrical connection between the docking station and the electronic device. In the related art, the opposing connector blocks can be connected to the lever through a hinge or a cam. Both the hinge and cam are described in U.S. Pat. Pub. 2013/0148289 of Kitae Kwon, particularly in FIG. 1A, FIG. 1B (cam), and FIG. 4 (hinge). See also U.S. Pat. Pub. 2012/0127651 of Kitae Kwon, et. al. 
         [0009]    There are some disadvantages of the related art systems. For example, the related art docking stations rely on a lever to so that a user can manually actuate the connector blocks. The lever is generally offset from the axis of the connector blocks the lever can be accessible by a user. An offset lever creates a non-linear force on the connector block and can cause misalignment of the connector block and prevent the connector block from interfacing with the docked device as designed. The lever also has the disadvantage that it must be moved to effectuate docking and undocking. The lever can be challenging to manipulate on a crowded desk or by a person having limited dexterity. 
         [0010]    The related art docking stations that using on a motor rely on sliding arms that are connected to an underside of the tray such as in Vroom. The sliding arms and sliding connection points of Vroom are a point of precision from which all other movement is indexed. For example, the arms of Vroom are slidably connected to the underside of the tray, the arms are connected to port blocks, the port blocks have connectors, and the connectors are positioned to interface with ports of a corresponding electronic device. However, the indexing point in Vroom (the underside of the tray) is distant from the position that precision is required (i.e. the point where the connectors are inserted into the electronic device.) Vroom therefore discloses undesirable tolerance stacking as between the indexing point and the point where precision is required. This requires adherence to very strict tolerances and increases manufacturing costs. 
         [0011]    The rack-and-pinion arms of Vroom are precision-manufacture components that must be particularly sized, scaled, and designed for use in a particular model docking station. The rack-and-pinion arms of Vroom are not interchangeable with other docking stations and cannot easily be substituted into other models of docking stations due to differing dimensions. 
         [0012]    The related art docking stations are also generally passive—the dock does not have awareness of whether an electronic device is present or if the connectors of the connector blocks are inserted into the docked device. A passive docking station cannot, for example, detect whether the electronic device is properly positioned within the dock. 
         [0013]    The related art docking stations also have a predetermined range of motion for the connector blocks. This range of motion is determined by the length of the lever arms and hinges or the size of the cam. Mechanical devices, however, tend to wear with extended use. As the related art begins to wear, the range of motion for the connector blocks can become sloppy or loose. Because docking requires high tolerances, a loose connector block could cause misalignment or incomplete insertion. 
         [0014]    The related art of Helot, requires that the electronic device includes a docking connector. Thus the docking station of Helot cannot be used with electronic devices that do not include a docking connector. Helot is also limited in that Helot does not provide a mechanism to secure either the electronic device or the docking station. While Kwon teaches using multiple plugs instead of a docking connector and using a Kensington-style lock to secure the electronic device and docking station, Kwon does not allow removal of the electronic device without also manually removing the Kensington-style lock.

As shown in  FIG. 5E , a plurality of fingers  115   a - 115   c  can pass through the holes or cutouts (not labeled) in the sidewall  135   a  of the tray (not labeled) and protrude from an interior surface  145   a  of the left side wall  135   a  to contact a top surface of an electronic device  165  thereby retaining the electronic device in the docking station. Similarly, a connector  120  can pass through one of the holes or cutouts (not labeled) in the sidewall  135   a  of the tray (not labeled) and protrude from an interior surface  145   a  of the left side wall  135   a  to interface with a corresponding port (not shown) of the electronic device  165  thereby retaining the electronic device in the docking station. 
         [0074]    Although the invention has been shown and described in conjunction with a left side wall having three fingers and one connector, other embodiments are contemplated within the scope of this invention including variations of the foregoing. These variations include, for example, one, two, three or more fingers on one side; one, two, three or more connectors on one side; different combinations of connectors and fingers on two or more sides; at least one finger and one connector on one side and at least one finger and one connector on an opposite side; a second side horizontally opposed to a first side; at least one connector and one finger on one side and at least one finger on a second side; at least one connector and one finger on one side and a dummy connector on a second side; and one or more fingers on a first side and one or more connectors on a second side and horizontally opposed to the first side. 
         [0075]      FIG. 6  is an isometric view of a drivetrain according to an exemplary embodiment of the invention. As shown in  FIG. 6 , a drivetrain  200  for a docking station can include a driveshaft  210 , threaded portions  215   a  and  215   b , an electric motor  230 , and gears  220 . The electric motor  230  can be connected to the gears  220 . One of the gears  220  can be a linking gear  240  that connects the gears  220  to the driveshaft  210 . The driveshaft  210  can have two ends  211  and  212 . The ends  211  and  212  of the drive shaft  210  can be hexagonal, keyed, or have other similar features for receiving threaded portions  215   a  and  215   b  and prevent the threaded portions  215   a  and  215   b  from rotating about the ends  211  and  212 . The threaded portions  215   a  and  215   b  can be capped with limiting washers  216   a  and  216   b . The threaded portions  215   a  and  215   b  and the respective limiting washers  216   a  and  216   b  can be retained on the ends  211  and  212  with retaining member such as retaining clip  217 . 
         [0076]    The gears  220  can be reducing gears that function to decrease the rotational speed and increase the power of the motor  230 . Small electric motors typically operate at high speeds, such as 1,200 rpm, 1,800 rpm, or greater. Gears  220  can effectively reduce the rotational speed of the motor  230  at the driveshaft  210  and increase the power. The gears  220  can be coupled to the driveshaft  210  via a linking gear  240 . The linking gear  240  can be fixed to the driveshaft  210  such that rotating the linking gear  240  causes the driveshaft  210  to rotate as well. When electrical power is applied to the motor, the motor can spin at high speed, the speed can be reduced and the power increased by way of the gears  220 . The rotational energy can be transmitted to the driveshaft  210  by the linking gear  240 . Rotation of the driveshaft  210  can, in turn, cause rotation of the threaded portions  215   a  and  215   b  that are fixed to the ends  211  and  212  of the driveshaft  210 . The threaded portions  215   a  and  215   b  can be connected to corresponding threaded receiving portions of port blocks (not shown) of a docking station causing the port blocks to translate over the threaded portions and move from an open position to a closed position, or vice versa. 
         [0077]    The drivetrain  200  can further include and emergency override gear  250  having a tool-receiving portion  255 . The emergency override gear  250  can be coupled to the driveshaft via linking gear  260 . In the alternative, the emergency override gear  250  can be coupled to the driveshaft via linking gear  240 . The tool-receiving portion  255  can be, for example, a hexagonal socket for receiving an Allen wrench. In another example, the tool-receiving portion  255  can be shaped to receive a different tool, such as a Torx wrench, flathead screw driver, phillips screw driver, or other tool for imparting rotational force. In the event of a power failure or other mechanical failure, a user can turn the emergency override gear  250  by rotating the tool-receiving portion  255  with an appropriate tool. Rotating the emergency override gear  250  can cause the driveshaft  210  and its threaded portions  215   a  and  215   b  to rotate thereby translating the port blocks (not shown) from a closed position to an open position. 
         [0078]      FIG. 7  is an isometric view of threaded ends of a driveshaft according to exemplary embodiments of the invention. As shown in  FIG. 7 , the driveshaft  210  includes threaded portions  215   a  and  215   b , limiting washers  216   a  and  216   b , and retaining clip  217 . The threaded portion  215   a  and limiting washer  216   a  can be disposed at one end  211  of the driveshaft  210 . The threaded portion  215   b  and limiting washer  216   b  can be disposed at an opposite end  212  of the driveshaft  210 . The ends  211  and  212  of the drive shaft  210  can be hexagonal or keyed such that the threaded portions  215   a  and  215   b  are constrained to rotate together with the driveshaft  210 . The retention clip  217  can hold the threaded portion  215   b  and limiting washer  216   b  on the end  212  of the driveshaft  210 . Although not shown, the other end  211  can similarly include a retention clip to hold the threaded portion  215   a  and limiting washer  216   a  on the end  211  of the driveshaft  210 . 
         [0079]    The threaded portions  215   a  and  215   b  can be inserted into interface portions of port blocks (not shown) that have matching female threads. When the driveshaft and threaded portions  215   a  and  215   b  are rotated, the port blocks can move up and down the threaded portions  215   a  and  215   b . The limiting washers  216   a  and  216   b  can prevent the threaded portions  215   a  and  215   b  from over rotating and unscrewing from the port blocks (not shown). 
         [0080]    The threaded portion  215   a  can have an opposite-handed thread than that of the threaded portion  215   b . The threaded portion  215   a  can have a left-hand thread and the threaded portion  215   b  can have a right-hand thread. Having an opposite thread on the threaded portions  215   a  and  215   b  can cause the port blocks to move in opposite directions. For example, rotating the driveshaft  210  and the threaded portions  215   a  and  215   b  in one direction can cause the port blocks (not shown) to move apart to an open position. Conversely, rotating the driveshaft  210  and the threaded portions  215   a  and  215   b  in the opposite direction can cause the port blocks (not shown) to move together to a closed position. It is undesirable for the threaded portions  215   a  and  215   b  to have the same handedness thread because rotation of the driveshaft  210  would cause the port blocks to move in the same direction and maintain an equal spacing between them preventing the port blocks from reaching a fully open or closed position. 
         [0081]      FIG. 8  is an isometric view of a gear system according to an exemplary embodiment of the invention. As shown in  FIG. 8 , the gear system includes a motor  230 , reducing gears  220  having linking gear  240 , a driveshaft  210 , emergency override gear  250 , tool-receiving portion  255 , and second linking gear  260 . 
         [0082]    The motor  230  can be connected to the gears  220  such that turning on the motor  230  will cause the gears  220  to rotate. The gears  220  can be configured in a reducing fashion such that rotational speed of the motor  230  is reduced through the gears  220  and the rotational speed at the linking gear  240  is much less. Similarly, by reducing the rotational speed, the gears can provide additional power to rotate the driveshaft  210  and can overcome the insertion force required to insert ports of a port blocks (not shown) into the corresponding ports of an electronic device. The linking gear  240  can be fixed to the driveshaft  210  so that rotating the linking gear  240  causes the driveshaft  210  to rotate. 
         [0083]    Embodiments of the invention further include an emergency override gear  250  having a tool-receiving portion  255 . In the event of electrical or mechanical malfunction, a user can manually rotate the emergency override gear  250  by turning the tool-receiving portion  255 . The Emergency override gear  250  can be connected to the driveshaft  210  by linking gear  260  or, in the alternative, linking gear  240 . 
         [0084]      FIG. 9  is an isometric view of a port block connected to a driveshaft according to an exemplary embodiment of the invention. As shown in  FIG. 9 , a drivetrain for a docking station can include a driveshaft  210 , a threaded portion  215   a  disposed on an end  211  of the driveshaft, a port block  110 , a drivetrain interface  125 , and a receiving portion  126  of the drive train interface. The receiving portion  126  of the drive train interface can be threaded to match and receive the threaded portion  215   a  of the driveshaft  210 . In operation, a motor and gears can rotate the drive shaft and threaded portion  215   a  causing the port block  110  to move or slide up and down the driveshaft  210 . Limit washer  216   a  can be provided at an end of the driveshaft  210  to prevent over-rotation of the driveshaft  210  and prevent the threaded portion  215   a  from becoming disconnected from the receiving portion  126  of the drive train interface  125  of the port block  110 . 
         [0085]      FIG. 10  is an isometric view of a port block connected to a driveshaft in a chassis according to an exemplary embodiment of the invention. As shown in  FIG. 10 , a drivetrain for a docking station can include a chassis  155 , a port block  110 , a drive shaft  210 , and a pillow block  310 . The driveshaft  210  can be connected to the port block  110  such that rotating the driveshaft  210  causes the port block to translate from an open to a closed position. The port block  155  and driveshaft  210  can be disposed in a chassis  155 . The chassis  155  can further include a pillow block  310  for supporting and stabilizing the driveshaft  210 . A mating cap (not shown) for the pillow block  310  can be provided on the underside of the tray (generally,  FIG. 2 ) to secure the driveshaft  210  in the pillow block  310 . 
         [0086]      FIG. 11A  is a rear view of a docking station according to an exemplary embodiment of the invention and  FIG. 11B  is a detailed view of a rear portion of a docking station with a chassis portion removed show internal details according to an exemplary embodiment of the invention. As shown in  FIG. 11A  and  FIG. 11B , a docking station can include a chassis  155 , plurality of ports  320 , a Kensington-style security hole  330 , an emergency override gear  250 , a tool-receiving portion  255 , a linking gear  260 , a linking gear  240 , and a drive shaft  210 . 
         [0087]    The Kensington-style security hole  330  can be rectangular shaped extending approximately 7.5 millimeters in width and 3.65 millimeters in height. The security hole  330  can be disposed on a rear portion of the chassis  155 . The chassis and/or the security hole  330  can be formed from metal for added security. The security hole  330  can be disposed such that it covers a tool-receiving portion  255  of the emergency override gear  250 . When a locking device is inserted and locked in the security hole  330 , access to the tool-receiving portion  255  of the emergency override gear  250  is blocked thereby securing the docking station and any docked computer from theft. Blocking access to the tool-receiving portion  255  of the emergency override gear  250  also prevents nefarious parties from manually actuating the port blocks from a closed position to an open position and removing a docked electronic device. When the security hole  330  does not have a lock in it, the tool-receiving portion  255  of the emergency override gear  250  can be easily accessed with an appropriate tool such as an Allen wrench. 
         [0088]    Turning the tool-receiving portion  255  of the emergency override gear  250  causes the linking gear  260  to rotate the driveshaft  210  thereby causing the port blocks (not shown) to translate from a closed to an open position. In an alternative embodiment, the emergency override gear  250  is connected to the linking gear  240  in which case the linking gear  260  can be omitted. 
         [0089]      FIG. 12A  is an assembly view of a port block according to an exemplary embodiment of the invention and  FIG. 12B  is an isometric view of a port block according to an exemplary embodiment of the invention. As shown in  FIG. 12A  and  FIG. 12B , a port block  410  can include a plurality of fingers  415   a ,  415   b ,  415   c , a connector  420 , alignment members  425   a ,  425   b ,  425   c , stand-offs  430   a ,  430   b , and a coupling nut  440 . The stand-off  430   a  can include a hole (not shown) for receiving a screw  445   a . The stand-off  430   b  can include a hole  450   b  for receiving a screw  445   b.    
         [0090]    The coupling nut  440  can slide into the stand-offs  430   a ,  430   b . The coupling nut  440  can receive a threaded portion of the drive train (e.g.  FIG. 7, 215   a ). The coupling nut  440  can be attached to the stand-off  430   a  via screw  445   a . The coupling nut  440  can be further attached to the stand-off  430   b  via screw  445   b  inserted through hole  450   b . In assembling a docking station, a step can be to connect the port block nut  440  to the stand-offs  430   a ,  430   b  with screws  450   a ,  450   b . In this way, the port block  410  cannot be separated from the drive train (not shown) without removing the screws  450   a ,  450   b.    
         [0091]    Alignment members  425   a ,  425   b ,  425   c  can slide within corresponding cavities or channels in the tray (not shown) of the docking station. Thus, when the port block  410  is connected to the drive train (not shown) via coupling nut  440  and screws  450   a ,  450   b , the tray (not shown) cannot be removed because the tray (not shown) is connected to the port block  440  via alignment members  425   a ,  425   b ,  425   c . Alignment members  425   a ,  425   b ,  425   c  can further provide for alignment of the port block  440  with respect to the tray (not shown) and the corresponding ports of an electronic device disposed in the tray. 
         [0092]      FIG. 13  is an isometric view of a tray according to an exemplary embodiment of the invention. As shown in  FIG. 13 , a tray  510  can include a plurality of sockets  525   a ,  525   b ,  525   c . The sockets  525   a ,  525   b ,  525   c  can receiving the alignment members  425   a ,  425   b ,  425   c  shown in  FIG. 12 . In embodiments of the invention, the sockets  525   a ,  525   b ,  525   c  can be deep and the corresponding alignment members  425   a ,  425   b ,  425   c  of a matching length such that the tray  510  can only be removed from the docking station when the port block is removed from the drive train via removal of screws  445   a ,  445   b  shown in  FIG. 12 . 
         [0093]      FIG. 14A  and  FIG. 14B  are assembly views of a port block, tray and drivetrain according to an exemplary embodiment of the invention. As shown in  FIG. 14A  and  FIG. 14B , a docking station includes a port block  410 , a tray  510 , and a drive train (not labeled). The port block  410  can include alignment members  425   a ,  425   b ,  425   c  and stand-offs  430   a ,  430   b . The stand-offs  430   a ,  430   b  can include holes  450   a ,  450   b  for receiving screws  445   a ,  445   b . The tray  510  can include a plurality of sockets  525   a ,  525   b ,  525   c.    
         [0094]    When assembled as shown in  FIG. 14B , the screws  445   a ,  445   b  can pass through the holes  450   a ,  450   b  in the stand-offs  430   a ,  430   b  thereby connecting the port block  410  to the coupling nut  440  of the drive train (not labeled). Similarly, the alignment members  425   a ,  425   b ,  425   c  can slidably connect to corresponding sockets  525   a ,  525   b ,  525   c . In this way, the port block  410  functions as a linking member connecting the drive train and the tray  510 . 
         [0095]      FIG. 15A  is an isometric view of a left side of a chassis according to an exemplary embodiment of the invention and  FIG. 15B  is an isometric view of a right side of a chassis according to an exemplary embodiment of the invention. As shown in  FIG. 15A  and  FIG. 15B , a chassis  655  can have holes  650   a ,  650   b ,  650   c ,  650   d . The holes  650   a ,  650   b  can be positioned within the chassis  655  to correspond to the position of corresponding holes  450   a ,  450   b  of the stand-offs  430   a ,  430   b  shown in  FIG. 14A  and  FIG. 14B  when the port block  410  is in an open position. The holes  650   c ,  650   d  can be positioned within the chassis  655  to correspond to the position of corresponding holes of the stand-offs of a second port block (not shown) when the second port block is in an open position. The chassis holes  650   a ,  650   b ,  650   c ,  650   d  can be sized to allow a screw, such as screw  445   a  or  445   b  of  FIG. 14B  to completely pass through the hole  650   a ,  650   b ,  650   c ,  650   d . In this way, the hole  650   a ,  650   b ,  650   c ,  650   d  functions as an access hole or pass-through hole for a screw. The screw can connect the port block to the drive train as shown in  FIG. 14B . The holes  650   a ,  650   b ,  650   c ,  650   d  can be positioned within the chassis such that a screw (such as screw  445   a  or  445   b  of  FIG. 14B ) can only be accessed through the hole with the docking station or the port block is in an open position. Conversely, when the docking station is in a closed position, the coupling nut that receives a screw slides inwards and cannot be accessed through the holes  650   a ,  650   b ,  650   c ,  650   d . In this way, an electronic device that is docked within the docking station cannot be removed from the docking station by disassembling the docking station because screws that hold the docking station together are not accessible through the holes  650   a ,  650   b ,  650   c ,  650   d  when the docking station is in a closed or docked state. In embodiments of the invention, the chassis is made from a metal adding further protection against theft of a docked electronic device. 
         [0096]      FIG. 16A  is an isometric view of a chassis and tray according to an exemplary embodiment of the invention and  FIG. 16B  is an isometric view of a chassis, tray, and perimeter foot according to an exemplary embodiment of the invention. As shown in  FIG. 16A  and  FIG. 16B , a docking station can have a chassis  655 , a tray  510 , and a perimeter foot  665 . The chassis  655  can have holes ( 650   a ,  650   b ,  650   c ,  650   d  of  FIG. 15A  and  FIG. 15B ) for receiving screws  445   a ,  445   b ,  445   c ,  445   d . The holes ( 650   a ,  650   b ,  650   c ,  650   d  of  FIG. 15A  and  FIG. 15B ) can be large than the screws  445   a ,  445   b ,  445   c ,  445   d  such that the screw and the head of the screw can pass completely through its corresponding hole. The screw can connect a portion of the port block to a portion of the drive train. In preferred embodiments of the invention, the screws  445   a ,  445   b ,  445   c ,  445   d  connect a stand-off of the port block to a coupling nut of the drive train. The port blocks can slide between an open position and a closed position. When the port block is in an open position, the screws  445   a ,  445   b ,  445   c ,  445   d  can be passed through the corresponding holes to connect the port block to the drive train. When the port block is in a closed position, the coupling nut slides inwards along the threaded portion of the drive train (see e.g.  FIG. 7 ) moving the head of the screw such that it cannot be accessed through the holes ( 650   a ,  650   b ,  650   c ,  650   d  of  FIG. 15A  and  FIG. 15B ). Because the screws  445   a ,  445   b ,  445   c ,  445   d  cannot be accessed when the port block is in the closed position, the docking station cannot be disassembled thereby preventing theft of an electronic in the docking station. 
         [0097]    The perimeter foot  665  can be inserted into a corresponding recess  660  on the bottom of the chassis  655 . The perimeter foot  665  can cover or hide the access holes ( 650   a ,  650   b ,  650   c ,  650   d  of  FIG. 15A  and  FIG. 15B ). The perimeter foot  665  can be formed from rubber or silicon or other durable material to provide a resilient and anti-slip base for the docking station. 
         [0098]      FIG. 17  is an isometric view of a chassis and drive train according to an exemplary embodiment of the invention. As shown in  FIG. 17  a docking station can include a chassis  655  and a drive train (shown in broken line). The embodiment in  FIG. 17  shows a docking station in a closed state. A port block has been omitted for clarity although generally, a port block can be connected to the coupling nut  440  via stand-offs as shown in  FIG. 14B .  FIG. 17  illustrates how the screws  445   a ,  445   b  that can connect the port block (not shown) to the coupling nut  440  slide right or inwards when the docking station and port block is in a closed state. As shown in FIG.  17 , the screws  445   a ,  445   b  cannot be accessed through holes  650   a ,  650   b . Access to the screws  445   a ,  445   b  is obscured by the chassis  655 . 
         [0099]    When assembling a docking station, the port block can be the last major component added to the assembly. The port block can effectively couple the tray to the drive train and thereby the chassis. The alignment members of the port block can couple the port block to the tray. The stand-offs can couple the port block to the coupling nut  440  of the drive train. The drive train can be coupled to the chassis with screws (not shown). The port block can be slidably introduced into the docking station via a side of the chassis. In the example of  FIG. 17 , a port block can slide into the chassis from the left hand side. Once inserted, the alignment members of the port block can enter into corresponding sockets of the tray. Stand-offs of the port block can connect to a coupling nut of the drive train. Screws can be used to connect the coupling nut of the drive train to the stand-offs of the port block. Holes can be provided in the chassis such that the screws can be inserted when the docking station is in an open or undocked state. The position of the holes in the chassis can correspond to the position of holes in the coupling nut when the dock is in an open or undocked state. When the dock is transitioned to a docked or locked state, the coupling nut can slide along the threaded portion of a drive train. The screws that connect the coupling nut to the port block can move with the coupling nut such that the screws are not accessible via the access holes when the docking station is in a closed or locked state (as shown in  FIG. 17 ). 
         [0100]    It will be apparent to those skilled in the art that various modifications and variations can be made in the secure assembly for a motorized docking station without departing from the spirit or scope of the invention. Thus, it is intended that embodiments of the invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
