Adjustable shelf system

1. An adjustable shelf system, comprising:

a first pair of track members;

a second pair of track members;

a shelf having a forward end, a rearward end, and a first side and a second side between the forward and rearward ends; and

a pair of leveraging members extending from said first and second sides and located between said forward and rearward ends, wherein the shelf is operatively connected to said first and second pair of track members, wherein the pair of leveraging members provide selective movement of the shelf between said first and second pair of track members, and further wherein the pair of leveraging members are movable within and selectively contact said first and second pair of track members for moving the shelf about the first and second pair of track members,

wherein the pair of leveraging members include

a pair of roller elements to permit said shelf to be

movably disposed within said one of the first and second pair of track members when said shelf is operatively connected to said one of the first pair of track members, and

leveragably disposed and movably disposed within the other of said first and second pair of track members, wherein the shelf includes at least one lever operatively connected to said the pair of roller elements by way of a coupling device for retracting the pair of roller elements that extend from said shelf.

2. The adjustable shelf system according to claim 1 , wherein the first and second pair of track members are C-shaped in cross-section.

3. The adjustable shelf system according to claim 1 further comprising

a third pair of track members that communicatively join said first and second pair of track members; and

a second pair of roller elements extending from said shelf that are movably-disposable within said first, second, and third pair of track members, wherein, as said first pair roller elements leverage said shelf about the other of said first and second pair of track members, said second pair of roller elements are moved from within said one of said first and second pair of track members to the other of said first and second pair of track members by way of movably-disposing said second pair of roller elements within the third pair of track members.

4. The adjustable shelf system according to claim 1 , wherein each of the first and second pair of track members are disposed in recesses formed in opposing substantially parallel surfaces.

5. The adjustable shelf system according to claim 4 , wherein the opposing substantially parallel surfaces are quarter panels in a passenger compartment of a vehicle.

6. The adjustable shelf system according to claim 5 , wherein the shelf includes at least one pair of retractable locking pins operatively connected to said lever by way of said coupling device, wherein, said retractable locking pins are located about opposing side-walls of the shelf.

7. The adjustable shelf system according to claim 6 , wherein the retractable locking pins are adapted to be received by bores formed in the and track members and quarter panels.

8. A method for selectively positioning a shelf in an adjustable shelf system comprising the steps of:

slidably moving a shelf from a first stowed position within a first pair of track members such that a first pair of roller elements is moved outwardly from and ceases contact with the first pair of track members;

pivoting the shelf about a first fixed axis passing through a second pair of roller elements located in the first pair of track members;

positioning the first pair of roller elements in a second pair of track members;

pivoting the shelf about a second fixed axis passing through the first pair of roller elements positioned in the second pair of track members; and

slidably moving the shelf to a second stowed position within the second pair of track members, wherein, prior to pivoting the shelf about the second axis step, further comprising the steps of actuating a lever operatively coupled to said second pair of roller elements by way of a coupling device and retracting the second pair of roller elements from the first pair of track members.

9. The method according to claim 8 , wherein the pivoting the shelf about a first fixed axis step further comprises bearing the weight of the shelf about the second pair of roller elements.

10. The method according to claim 8 , wherein the pivoting the shelf about the second fixed axis step further comprises bearing the weight of the shelf about The first pair of roller elements.

11. The method according to claim 8 , wherein the pivoting the shelf about the second axis step further comprises guiding the second pair of roller members through a third pair of track members that communicatively join the first and second pair of track members.

12. The method according to claim 8 further comprising the steps of de-actuating said lever and extending the second pair of roller elements from said retracted position into engagement within the second pair of track members.

13. The method according to claim 8 , wherein prior to the first slidably moving step, further comprising the steps of actuating a lever operatively coupled to at least one pair of locking pins by way of a coupling device extending from said shelf and retracting said at least one pair locking pins.

14. A method for selectively positioning a shelf in an adjustable shelf system comprising the steps of:

slidably moving a shelf from a first stowed position within a first pair of track members such that a first pair of pair elements is moved outwardly from and ceases contact with the first pair of track members;

pivoting the shelf about a first fixed axis passing through a second pair of roller elements located in the first pair of track members;

positioning the first pair of roller elements in a second pair of track members;

pivoting the shelf about a second fixed axis passing through the first pair of roller elements positioned in the second pair of track members; and

slidably moving the shelf to a second stowed position within the second pair of track members, wherein prior to the first slidably moving step, further comprising the steps of actuating a lever operatively coupled to at least one pair of locking pins by way of a coupling device extending from said shelf and retracting said at least one pair locking pins.
