## Background
The present invention relates to a mounting for retaining a computer within a vehicle, and for providing support functions to the computer, commonly referred to as a computer dock. In particular, the present invention relates to a mounting or computer dock which, when not in use, stores the computer in the armrest of a vehicle.

Technological advances in the semiconductor industry have resulted in very powerful computers being available in small sizes. The notebook computer can contain the computing capabilities of a larger PC, but the small size of such devices has limitations. One obvious limitation is battery power. A battery operated computer is useable for only a short time without recharging or replacing batteries. Small computers also require support facilities if they are to read CD ROMs, receive e-mail or interact with global positioning systems with the capabilities of a typical desk mounted computer.

My prior patent application Ser. No. 09/425,924 filed Oct. 25, 1999, disclosed an automobile mounted computer dock for providing support to a notebook computer. With the aid of the dock of my prior application, a notebook computer can perform all the functions which can be performed by on a home mounted PC's. The devise, as disclosed, however, was intended for use in the dashboard of a vehicle. The mounting of a computer to the dashboard, however, renders it unusable to passengers in the rear seat. Since a driver must direct his full attention to operating a moving vehicle, it would be desirable to have a dock which would render the computer usable by the passengers in the vehicle, including those in the rear seat.

Briefly, the present invention is embodied in a mounting for retaining a computer for use in the armrest of an automobile. The mounting, or dock, of the present invention has an enclosure defined by the outer surface of the armrest, the enclosure having a forward opening and a rearward opening and a passage extending through the enclosure connecting the two openings. A tray is mounted on a slide assembly for movement between three positions. In the first position the tray is forward of the forward opening, in the second position the tray is rearward of the rearward opening, and the third position the tray is within the enclosure. The tray has mounting devices, such as holes or clamps for retaining the notebook computer. Within the tray are electronic support functions for use with the computer and cables are provided to attach the functions available in the tray, or dock, to the computer.

Referring to FIG. 1, the interior of an automobile 10 includes a dashboard 12 having a steering wheel 13 behind which is the driver's seat 14. Opposite the driver's seat 14 is a front passenger seat 16, and behind the two front seats 14, 16 is a rear seat 18. Between the front seats 14,16, and visible to passengers in the rear seat 18, is a console or armrest 20.

Referring to FIGS. 2-4, the armrest 20 has opposing parallel sides 22, 23 and an upper surface 24 having sufficient rigidity to withstand impacts from passengers of the vehicle, and having an exterior which presents an esthetically attractive appearance. Within the enclosure defined by the sides 22, 23 and the upper surface 24 is a passage accessible from either a forward opening 26 or a rearward opening 27 and moveable therethrough is a tray 28 to which a computer 29 is attached as is further described below. The tray 28 includes connectors for connecting the computer 29 to circuits, as is also described below, which supplement the computer 29. The tray 28, therefor, is a computer dock, and is hereafter interchangeably referred to as either a "tray" or a "computer dock".

Referring to FIGS. 3 and 4, the forward opening 26 of the enclosure is closed by a door 30 made of a plurality of hinged panels so as to be moveable along a curved track 31 having an elongate end 32 into which the door is slideable when the door 30 is opened. Similarly, the rearward opening 27 of the enclosure is closed by a door 33 made of a plurality of hinged panels so as to be moveable along a second curved track 34 having an elongated end 35 into which the door 33 is slideable when the door 33 is opened. As can be seen, the tracks for the forward and rearward door 30, 33 cross each other at an intersection 36, such that when one door 30, 33 is opened (door 33 is depicted as being opened in FIG. 3), the opened door 33 will extend through the intersection 36 and prevent the other door 30 from being opened.

Referring to FIGS. 2, 5-8, positioned longitudinally along the bottom surface 38 of the armrest 20 is a pair of parallel guides 40, 42 each of which has horizontally extending flanges 40A, 40B and 42A, 42B the longitudinal edges of which are all parallel. Fitted around each of the guides 40, 42 is a pair of slides 44, 46 having a generally rectangular cross section.

As best shown in FIG. 5, each slide 44, 46 of which number 46 is representative or both, has a planar upper surface 48, parallel opposing sides 49, 50 and extending towards each other from the lower edges of each of the sides 49, 50 are inwardly extending flanges 51, 52 respectively. As best shown in FIGS. 2 and 8, the inwardly extending flanges 51, 52 of each of the slides 44, 46 extend around the flanges 40A, 40B and 42A, 42B respectively such that the slides 44, 46 are longitudinally moveable along their associated guide 40, 42.

Referring to FIGS. 2 and 8, one side 50 of each of the slides 44, 46 has an elongate slot 54, and the slots 54 are oriented adjacent to each other and spaced apart a distance to allow a center slide member 56 to move between them. The center slide member 56 has a pin 58 extending transversely through an end piece 57 thereof and the opposing ends of the pin 58 extend into the slots 54 of the slides 44, 46.

Referring to FIGS. 6, 7, and 8, the end piece 57 of the center slide member 56 has parallel sides 59, 60 which fit snuggly between the parallel sides 50 of the slides 44, 46 so as to be longitudinally slideable with respect to the slides 44, 46 while being retained between the slides 44, 46 by the pin 58.

Pivotally attached to the end piece 57 by a second horizontal pin 62 is a vertically moveable pivot member 64, and axially rotatable about a longitudinal pin 66 extending into the pivot member 64 is a mounting arm 68. The mounting arm 68 is preferably made of sheet metal shaped into a rectangular cross section with a planar top 70 parallel sides 72, 74 and a bottom 76. Extending longitudinally through the planar top 70 is an elongate slot 78. Referring to FIGS. 4 and 7, mounted on a fourth pin 80 which extends through the slot 78 is a turntable 82, and mounted to the turntable 82 is the computer dock 28.

As can be seen, the slides 44, 46 are longitudinally moveable with respect to the guides 40, 42 and can be extended outward through either the forward opening 26 or the rearward opening 27 of the armrest 20. The computer dock 28 is mounted on the center slide member 56, and the center slide member 56 is longitudinally moveable with respect to the slides 44, 46. The longitudinal movement of the center slide member 56 is limited by the pin 58 contacting the ends of the slots 54 in the slides 44, 45. The computer dock 28 is also longitudinally moveable with respect to the center slide member 56 by movement of the pin 80 within the slot 78 in the mounting arm 68. These three portions, the slides 44,46, the center slide member 56, and the pin 80 allow extended linear movement of the dock 28, as is further described below.

The dock 28 may also be tilted by rotation of the pivot member 64 about the pin 62. As can be seen, the axis of the pin 62 is perpendicular to the direction of the linear movement of the dock described above. The dock 28 is also rotatable about the longitudinal pin 66, which is perpendicular to the pivot pin 62 and lies with a plane containing the line of movement of the longitudinally moveable parts. Finally, the dock 28 is also rotatable on the turntable 82 and the pin 80 with respect to the mounting arm 68.

Referring to FIGS. 9, 10, and 11, the dock 28 includes computer supports functions, specifically a CD ROM 83, a cell phone 84, a modem 85, and a global positioning system 86. Connector cables 88, 89, 90 extend from the CD ROM 83, the modem 85 and the global positioning system 86, respectively, for attachment to jacks on the notebook computer 29. The computer 29 is removeably retained to the dock 28 by any suitable means, such as screws, not shown, extending through mounting holes 91, 92. The dock 28 also has a cable 93 for providing power from the battery and power system of the vehicle, not shown, to the notebook computer 28 and cables 94, 95 for attaching the cell phone 84 and the global positioning system 86, respectively, to a suitable antenna. With the support functions provided by the computer docks a notebook computer 29 attached thereto has all the capabilities of a conventional PC.

Referring to FIGS. 12-17, when the computer 29 is attached to the dock 28, the computer is moveable longitudinally as the slides 44, 46 move with respect to the guides 40, 42 and the center slide member 56 moves with respect to the slides 44, 46. The computer 29 and dock 28 are moved forward through the forward opening 26 as shown in FIGS. 12 and 13 where it is visible to the passengers in the front seats of the vehicle 10. It may also be moved through the rear open 27 to the position shown in FIGS. 15 and 16 where it is visible by passengers in the rear seat 18. When not in use, the computer 28 and dock 29 can be stored within the armrest 20 with the doors 30, 33 closed.

In the embodiment depicted in FIGS. 12-17, the notebook computer 29 is provided with a double hinge assembly of the type disclosed in my previously filed patent application Ser.
