Vehicle shelf system and method of use

1. A shelf system, comprising:

at least one upright member;

a biasing member having a first end and a second end, said first end directly attached to said upright member via a ball stud;

a shelf member supported by an under-shelf bracket and adapted for pivotal motion with respect to said at least one upright member; and

a spanner bracket having a first end portion connected said at least one upright member and a second end portion forming a pivot axis for said shelf member,

wherein said second end of said biasing member is connected to a rear portion of the shelf member.

2. The shelf system of claim 1 , further comprising a first and a second upright member, wherein each upright member is comprised of a central body flange bounded by two side flanges, wherein said side flanges are parallel one another but they are not coplanar with said central body flange, wherein said first and second upright members are spaced apart from one another.

3. The shelf system of claim 1 , wherein said biasing member comprises

a piston.

4. The shelf system of claim 1 , wherein said second end of said biasing member has a flat with an aperture, said flat is received within two mounting ears, said ears each having apertures aligned with said aperture in said flat, wherein an ear fastener extends through the all of said apertures.

5. The shelf system of claim 4 , wherein said mounting ears are formed on an end portion of a mounting plate, said mounting plate is connected to said under-shelf bracket.

6. The shelf system of claim 5 , wherein said under-shelf bracket comprises two parallel ribs connected by a central flange, wherein said mounting plate is connected under said ribs and parallel said central flange.

7. The shelf system of claim 6 , wherein aligned apertures are located through said ribs, a bushing is located in said rib apertures and a spanner bracket fastener is located in said bushing, wherein said bushing, said rib apertures and said spanner bracket fastener form part of, and are aligned with, said pivot axis.

8. The shelf system of claim 7 , wherein said spanner bracket is L-shaped, and said second end portion has an aperture for receiving said spanner bracket fastener therethrough, wherein said spanner bracket cantilevers said shelf member from said upright member.

9. The shelf system of claim 8 , wherein said aperture in said second end portion of said spanner bracket forms part of, and is aligned with, said pivot axis.

10. A shelf system, comprising:

a first upright member and a second upright member, said upright members forming an upright member plane,

at least one floor rail with a U-shaped cross section comprised of an inner lip and an outer lip separated by an offset, wherein the outer lip is located in the upright member plane,

at least one mid-rail with a Z-shaped cross section comprised of a upstanding flange, a mid-span flange and a downstanding flange, wherein the downstanding flange is coplanar with the outer lip and the upright member plane;

at least one upper rail of substantially constant thickness, wherein said rail has a longitudinal portion and at least one transverse portion extending from the longitudinal portion, wherein said upper rail resides in said upright member plane.

11. The shelf system of claim 10 , wherein said upright members comprise a central flange bounded by two side flanges, wherein said side flanges reside in said upright member plane.

12. The shelf system of claim 10 , wherein at least one cross piece spans between and connects said upright members together.

13. The shelf system of claim 10 , wherein a planar panel is located between said upright members and attached to said side flanges so that said planar panel is located in said upright member plane.

14. The shelf system of claim 10 , further comprising a shelf member adapted for pivotal attachment to said upright members via a biasing member connected to one of said upright members and said shelf member.

15. The shelf system of claim 14 , further comprising a pivot axis for said shelf member with respect to a spanner bracket connected to an upright member, wherein said pivot axis is located above a connection between a biasing member and the shelf member, wherein said pivot axis is comprised of aligned apertures in ribs of an under-shelf bracket, a bushing in said apertures, and a fastener in said bushing.

16. A method of pivoting a shelf in a shelf system,

comprising:

providing a shelf member adapted to be moved between a raised position and a lowered position, wherein an under-shelf bracket supports the shelf member;

pivoting said shelf member about a pivot axis formed through portion of a spanner bracket connecting said shelf member to a stationary upright member, said pivot axis located above of an under-shelf bracket and a biasing member intersection;

changing the length of a biasing member while simultaneously changing the angle of the biasing member with respect to the stationary upright member when pivoting the shelf member between the raised position and the lowered position;

cantilevering said shelf member from said at least one upright member with said spanner bracket,

wherein a second end of said biasing member is connected to a rear portion of the shelf member.

17. The method of claim 16 , further comprising accommodating a central flange of said upright member within an upright member recess in a back edge portion of said shelf member when said shelf member is in the lowered position.

18. The method of claim 17 , further comprising accommodating a spanner bracket within a spanner bracket recess in said back edge portion of said shelf member when said shelf member is in the lowered position, wherein said spanner bracket recess is connected to said upright member recess.

19. The method of claim 16 , wherein in said lowered position, said shelf member does not extend into an upright member plane formed by said upright member, a portion of a floor rail, a portion of at least one mid-rail and a portion of at least one upper rail.
