DETAILED DESCRIPTION

One embodiment of a stowable table unit system 10 is shown in FIGS. 1-8. As shown in FIG. 1, the stowable table unit system 10 is in a stowed position in a ceiling 12 of a vehicle 14. The vehicle 14 has front seats 16 and rear seats 18. The front seats 16 are adapted to be rotated about one hundred eighty degrees (180°) to face the rear seats 18. FIG. 2 shows the stowable table unit system 10 in a deployed position within the vehicle 14. As shown in FIG. 2 the stowable table unit system 10 deploys to a position between the front seats 16 and the rear seats 18. The stowable table unit system 10 generally includes a table portion 20 and a support leg portion 22.

As shown in FIG. 3, the support leg portion 22 is adapted to store within a bottom surface 24 of the table portion 20 when the stowable table unit system is in a stowed position. The table portion 20 mounts to a B-pillar 26 of the vehicle 14 via a mounting bracket 28 of the table portion 20. A plurality of electrical outlets 30 are located proximate the mounting bracket 28 on the stowable table unit system 10, while an additional plurality of electrical outlets 30 are located on the table portion 20 at an end of the table portion 20 opposite the mounting bracket 28. The electrical outlets 30 may be connected to an electrical system of the vehicle 14 to provide electrical power for accessories such as computers, battery chargers, lights, or other accessories. When the support leg portion 22 of the stowable table unit system 10 is stowed within the table portion 20, a generally flush surface is formed by the leg portion 22 and the bottom surface 24 of the table portion 20.

Turning now to FIG. 4, a frame of the stowable table unit system 10 is shown. The table portion 20 has a first support member 32 located at a first side of the table portion 20 and second and third support members 34a, 34b located at a second side of the table portion 20. The first, second and third support members 32, 34a, 34b extend along a first direction of the table portion 20. A first cross member 36a and a second cross member 36b extend between the first support member 32 and the second and third support members 34a, 34b at a first edge of the table portion. A third cross member 38a and a fourth cross member 38b extend between the first support member 32 and the second and third support members 34a, 34b at a second edge of the table portion. The first and second cross members 36a, 36b and the third and fourth cross members 38a, 38b are generally perpendicular to the first, second, and third support members 32, 34a, 34b.

The mounting bracket portion 28 of the stowable table unit system 10 comprises a first bracket 44 and a second bracket 46. The first bracket 44 connects to the first and second cross members 36a, 36b. The second bracket 46 may run the length of the table portion 20, thus connecting to not only the first and second cross members 36a, 36b, but also to the third and fourth cross members 38a, 38b. It is contemplated that the second bracket 46 may form the first support member 32.

The first and second brackets 44, 46 are generally rectangular steel tubes of standard dimensions, such as two inch by one and one-half inch (2″×1.5″) tubing. The second and third support members 34a, 34b, and the cross members 36a, 36b, 38a, 38b are generally rectangular steel plate of standard dimensions, such as one and one-half inch by half inch (1.5″×0.5″) plate. Although steel, such as 1035 steel, may be used to form the brackets 44, 46 and support and cross members 34a, 34b, 36a, 36b, 38a, 38b, it is contemplated that other materials, such as aluminum, titanium, alloys of steel, other metals, or polymeric materials may be used.

Also shown in FIG. 4 is an actuator 40 for operating a linkage 42 that deploys the support leg portion 22 of the stowable table unit system 10. According to one embodiment, the actuator 40 is a linear actuator that connects to the linkage 42 in manner such that, as the actuator extends, the leg portion rotates from a stored position within the bottom surface 24 of the table portion to an extended position, such as shown in FIG. 2. The support leg portion 22 pivots about a rod 48 that connects to the first support member 32 and the second support member 34a. Similarly, retracting the actuator 40 attached to the linkage 42 causes the leg portion 22 to pivot about the rod 48 towards the stored position form the extended position.

Turning now to FIGS. 5-8, the stowable table unit system 10 is shown being moved from the stowed position to the deployed position. As shown in FIG. 5, the stowable table unit system 10 is in a first partially deployed position. The table portion 20 has been lowered from the vehicle ceiling (not shown), but the support leg portion 22 has not yet begun to deploy. A top surface 50 of the table portion 20 may be seen clearly in FIG. 5. The top surface 50 of the table portion has a plurality of cup holders 52 formed therein. The cup holders 52 are sized to receive a beverage container, such as a drink cup or soda can, such that the beverage container is less likely to be spilled onto the top surface 50 of the table portion 20.

A B-pillar 26 lifting mechanism 54 is also partially shown in FIG. 5. The lifting mechanism 54 includes a motor powered threaded rod 56 and a B-pillar bracket 58 (FIG. 10). As shown in FIG. 10, the B-pillar bracket 58 threadably mounts to the motor powered threaded rod 56 to move up and down the B-pillar 26 of the vehicle depending on the direction of rotation of the motor powered threaded rod 56. Rotation of the motor powered threaded rod 56 in a first direction causes the B-pillar bracket 58 to move downward, towards a deployed position, while rotation of the motor powered threaded rod 56 in a second direction, generally opposite the first direction, causes the B-pillar bracket 58 to move upwards, towards a stowed position. The mounting bracket 28 of the table portion 20 is adapted to mount to the B-pillar bracket 58. Thus, the movement of the B-pillar bracket 58 along the powered threaded rod 56 moves the table portion 20 between the stowed position to the deployed position.

As shown in FIGS. 5-8 the lifting mechanism 54 has a top ledge 59 and a bottom ledge 60 that limit the movement of the table portion 20 of the stowable table unit system 10. The top ledge 59 is located proximate a top of the B-pillar 26 and is positioned such that the top surface 50 of the table portion 20 contacts the lop ledge 59 when the table portion 20 is in the stowed position. Similarly, the bottom ledge 60 is disposed proximate a bottom of the B-pillar 26 and is positioned such that a lower surface of the mounting bracket 28 of the table portion 20 contacts the bottom ledge when the table portion 20 is in the deployed position.

FIG. 6 depicts the support leg portion 22 beginning to deploy from the table portion 20. The table portion 20 has been lowered along the B-pillar 26 by the lifting mechanism 54 relative to the position of the table portion 20 depicted in FIG. 5. As previously discussed in connection with FIG. 4, the actuator 42 extends such that the linkage 42 is manipulated to cause the leg portion 22 to pivot about rod 48 and extend from the table portion 20.

Similarly, FIG. 7 shows the support leg portion 22 extending still further from the table portion 20. The table portion 20 has been lowered along the B-pillar 26 by the lifting mechanism 54 relative to the position of the table portion 20 depicted in FIG. 6.

Turning now to FIG. 8, the stowable table unit system 10 is shown in a completely deployed position. The mounting bracket 28 of the table portion 20 contacts the bottom ledge 60 of the B-pillar 26. Additionally, the leg portion 22 is fully extended and contacts a floor 62 of the vehicle. The leg portion 22 provides additional support while the table portion 20 of the stowable table unit system 10 is in a deployed position, allowing the table portion 20 to support loads likely to be seen in operational use, up to about several hundred pounds.

A variety of materials may be used to cover the frame of the table portion 20 of the stowable table unit system 10. It is contemplated that a thermoplastic be used to form the top surface 50 and bottom surface 24 of the table portion. An example of a thermoplastic may be a polycarbonate and acrylonitrile butadiene styrene blend (PC/ABS blend). Such a blend has thermal and mechanical properties of polycarbonate, and the production benefits of ABS. an example of PC/ABS blend that may be utilized is Bayer Corporation's Bayblend® KU 1-1446 product.

Turning now to FIG. 9, another embodiment of a stowable table unit system 100 is depicted. The stowable table unit system 100 is similar to the stowable table unit system 10 described above, and identical components share the same reference numbers as described above. The stowable table unit system 100 has a table portion 64. The table portion 64 mounts to a B-pillar 26 of the vehicle 14 via the mounting bracket 28. The table portion 64 is moveable from a stowed position to a deployed position via the lifting mechanism 54.

A plurality of electrical outlets 30 are located proximate the mounting bracket 28 on the stowable table unit system 100, while an additional plurality of electrical outlets 30 are located on the table portion 64 at an end of the table portion 64 opposite the mounting bracket 28. The electrical outlets 30 may be connected to an electrical system of the vehicle to provide electrical power for accessories such as computers, battery chargers, lights, or other accessories.

When the support leg portion 22 of the stowable table unit system 100 is stowed within the table portion 64, a generally flush surface is formed by the leg portion 22 and a bottom surface of the table portion 64.

The table portion 64 has a top surface 66. The top surface 66 has a plurality of cup holders 52 located at each corner of the top surface 66 of the table portion 64. The top surface 66 of the table portion 64 additionally has a first storage unit 68 and a second storage unit 70. The first and second storage units 68, 70 are adapted to store small items such as pens, pencils, markers, computer accessories, power cords, battery chargers, or other small items.
