Consequently, the specific structural and functional details disclosed herein are merely representative, yet in that regard, they are deemed to afford the best embodiment for purposes of disclosure and to provide a basis for the claims herein which define the scope of the present docking station. The following presents a detailed description of an illustrative embodiment (as well as some alternative embodiments) of the present docking station.
In the Figures, like numerals indicate like elements.
With reference to the Figures, the present invention is a docking station 10 having docking tray 12 formed of a receiver portion 14 for receiving an electronic device 16, such as a portable laptop computer, or other portable electronic device intended to be operated with a docking station, and a clamping portion 18 for securing portable device 16 in mechanical and electrical contact with an extension connector 20 (FIG. 3) positioned in a base portion 22 of receiver portion 14 substantially opposite of clamping portion 18. The extension connector 20 is coupled to an extension module 24 positioned adjacent to base portion 22 of receiver portion 14. Receiver portion 14 also includes a latch mechanism 26, such as but not limited to a lockable latch. Latch mechanism 26 is optionally positioned adjacent to base portion 22 of receiver portion 14 adjacent to one side thereof.
Docking station 10 is operable between an open state (FIG. 1) having clamping portion 18 arranged in an expanded position spaced away from receiver portion 14 for receiving electronic device 16 into base portion 22 of receiver portion 14, and a closed state (FIG. 2) having clamping portion 18 arranged in a retracted position adjacent to receiver portion 14 for retaining electronic device 16 in docking tray 12.
FIG. 4 illustrates docking station 10 in the open state shown in FIG. 1 having clamping portion 18 arranged in the expanded position spaced away from receiver portion 14 for receiving electronic device 16 into base portion 22 with electronic device 16 engaged with extension connector 20. Here, clamping portion 18 is movably coupled to receiver portion 14, for example, in sliding connection therewith, for moving relative to receiver portion 14 between the open state and the closed state. Clamping portion 18 is movable by operation of a preload lever 28 coupled between receiver portion 14 and clamping portion 18 for driving alternately clamping portion 18 into the expanded position spaced away from receiver portion 14, and the retracted position adjacent to receiver portion 14.
For example but without limitation, preload lever 28 has a fulcrum portion 30 that is rotatably coupled to receiver portion 14 in a pivoting relationship therewith, and a load portion 32 that is coupled to clamping portion 18 in a driving relationship therewith, with a resistance arm 34 interconnecting load portion 32 and fulcrum portion 30. For example, a rotatable coupling 36 is formed of a pin 38 fixed in receiver portion 14 of docking tray 12 rotatably engaged with a mating aperture 40 formed in fulcrum portion 30 of lever 28. A sliding connection 42 is, by example and without limitation, formed as a pin 44 fixed in clamping portion 18 of docking tray 12 and slidingly engaged with a mating slot 46 formed in load portion 32 of lever 28. Load portion 32 structured between preload lever 28 and clamping portion 18 in a position between resistance arm 34 and an effort arm 48 of lever 28, wherein effort arm 48 is coupled for driving load portion 32 relative to fulcrum portion 30.
A latching portion 50 of lever 28 is releasably coupled with receiver portion 14 for retaining clamping portion 18 of docking tray 12 in the retracted position, and simultaneously preloading load portion 32 of lever 28 for compressing clamping portion 18 of docking tray 12 against receiver portion 14. For example, latching portion 50 of lever 28 is an aperture that engages latch mechanism 26 of receiver portion 14 for retaining clamping portion 18 of docking tray 12 against receiver portion 14 when lever 28 is operated (arrow 52) for driving clamping portion 18 along a travel axis (arrow 54) oriented substantially perpendicularly between clamping portion 18 and receiver portion 14.
FIG. 5 illustrates docking station 10 in the closed state of FIG. 2 having clamping portion 18 arranged in the retracted position adjacent to receiver portion 14 for retaining electronic device 16 in docking tray 12, wherein electronic device 16 is removed for clarity.
Optionally, one or more guides 56 are structured between clamping portion 18 of docking tray 12 and receiver portion 14 for guiding clamping portion 18 along travel axis (arrow 54) relative to receiver portion 14. For example, one or more extensions 58 of clamping portion 18 slide in one or more cavities 60 formed in receiver portion 14.
Optionally, clamping portion 18 of docking tray 12 is spring activated relative to receiver portion 14 for substantially automatically expanding docking tray 12 from closed state (FIG. 2) to open state (FIG. 1). For example, a compression spring or other resilient biasing mechanism 62 is positioned between extensions 58 of clamping portion 18 and cavities 60 in receiver portion 14 for urging clamping portion 18 away from receiver portion 14 along travel axis 54.
FIG. 6 illustrates receiver portion 14 of docking tray 12 having a mounting structure 64 for mounting docking station 10 in an automobile or other vehicle.
FIG. 7 illustrates lever 28 having a preload portion 66 that is structured for preloading load portion 32 of lever 28 when docking tray 12 is in the closed state (FIG. 2) at least with electronic device 16 installed therein. For example, either one or both of resistance arm 34 and effort arm 48 of lever 28 includes preload portion 66 embodied as a resiliently bendable member for applying a desired preload between clamping portion 18 and receiver portion 14 of docking tray 12 when docking tray 12 is in the closed state with electronic device 16 installed therein, whereby clamping portion 18 is preloaded in the retracted position with electronic device 16 clamped between base portion 22 of receiver portion 14 and clamping portion 18. For example, resiliently bendable member is a plate spring of a desired spring stiffness which is suited to the purpose of maintaining constant electrical contact between portable device 16 and extension connector 20 in base portion 22 of receiver portion 14.
Preferably, resiliently bendable lengthwise portion 66 of lever 28 is included as a portion of effort arm 48 positioned between load portion 32 and latching portion 50 of lever 28. Plate spring lengthwise portion 66 of effort arm 48 is sufficiently stiff to effectively retract clamping portion 18 relative to receiver portion 14 when operated by user, yet is sufficiently flexible for compressing clamping portion 18 of docking tray 12 against receiver portion 14 when docking tray 12 is in the closed state (shown) with electronic device 16 installed therein (FIG. 2).
Preload lever 28 is optionally a second class lever as illustrated having fulcrum portion 30 and latching portion 50 positioned adjacent to opposite ends thereof, with load portion 32 therebetween, similar to a wheelbarrow. Resistance arm 34 is positioned between fulcrum portion 30 and load portion 32, and effort arm 48 is positioned between load portion 32 and latching portion 50. Drive force 68 is applied to a handle 70 of lever 28 positioned adjacent to latching portion 50 at end of effort arm 48 opposite from fulcrum portion 30 and load portion 32.
Optionally, preload lever 28 is a first class lever similar to a see-saw with fulcrum portion 30 positioned between load portion 32 and effort arm 48, with resistance arm 34 positioned between fulcrum portion 30 and load portion 32. Although first class preload lever 28 is configured differently than shown for second class preload lever 28. In still another embodiment, preload lever 28 is a third class lever with fulcrum portion 30 positioned adjacent to a first end and load portion 32 positioned adjacent to the opposite end, with effort arm 48 positioned between fulcrum portion 30 and load portion 32, similar to a baseball bat.
In operation, as docking station 10 is alternately cycled between the open state (FIG. 1) and the closed state (FIG. 2), the fulcrum portion 30 of preload lever 28 is pivotable relative to receiver portion 14 by applying drive force 68 to handle 70 of lever 28. Simultaneously with pivoting of fulcrum portion 30 of preload lever 28, opposing latching portion 50 of preload lever 28 is rotatable (arrow 52) between an unlatched position that is disengaged and spaced away from latch mechanism 26 of receiver portion 14 and corresponds to the open state of docking station 10 having clamping portion 18 arranged in the expanded position thereof, and a latched position that is engaged with latch mechanism 26 and corresponds to the closed state of docking station 10 having clamping portion 18 arranged in the refracted position thereof. During operation (arrow 52) at least preload portion 66 of lever 28 is resiliently bent toward base portion 22 of receiver portion 14 and latch mechanism 26, whereby lever 28 is preloaded in the closed state of docking station 10. Accordingly, substantially constant electrical contact is maintained between portable device 16 and extension connector 20 in base portion 22 of receiver portion 14.
For removal of portable device 16, latching portion 50 of lever 28 is released from latch mechanism 26, whereby resilient preload portion 66 of lever 28 operates for springing latching portion 50 away from latch mechanism 26. When present, resilient biasing mechanism 62 urges clamping portion 18 away from receiver portion 14 along travel axis 54. Else, operator retracts clamping portion 18 away from receiver portion 14 along travel axis 54. Thereafter, portable device 16 is removable from receiver portion 14 of docking tray 12.
While the preferred and additional alternative embodiments of the invention have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention. Therefore, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention. Accordingly, the inventor makes the following claims.
