Abstract

A shelf assembly includes a rotating hinge body rotatably coupled to a stationary hinge body, and a shelf fixed to the rotating hinge body that is rotatable with the rotating hinge body relative to the stationary hinge body about a rotational axis. The shelf is rotatable between first and second positions. Moreover, the shelf assembly includes a cam assembly configured to inhibit rotation of the shelf between its first and second positions. The cam assembly includes a cam fixed to one of the stationary hinge body and rotating hinge body, a cam follower movably attached to the other of the stationary hinge body and rotating hinge body, and a biasing member that biases the cam follower into engagement with the cam. The rotatable shelf includes a glass panel having an upper surface with a plurality of edge portions. At least one of the edge portions is exposed.

First claim

What is claimed is:

1. A shelf assembly comprising:
a first support unit;
a stationary hinge body fixed to the first support unit;
a rotating hinge body rotatably coupled to the stationary hinge body;
a first shelf fixed to the rotating hinge body that is rotatable with the rotating hinge body relative to the stationary hinge body about a rotational axis, the first shelf being rotatable between a first position and a second position;
a cam assembly configured to inhibit rotation of the first shelf between its first position and second position, the cam assembly including:
a cam that is fixed to one of the stationary hinge body and rotating hinge body;
a cam follower slidingly coupled to the other of the stationary hinge body and rotating hinge body such that the cam follower is slidable along the rotational axis; and
a biasing member that biases the cam follower into engagement with the cam;

a second support unit that is separate from the first support unit;
a second shelf coupled to the second support unit; and
a coupling mechanism that couples the first support unit and second support unit to each other to inhibit relative movement between the first support unit and second support unit.

2. The shelf assembly according to claim 1 , wherein the coupling mechanism includes:
a first coupling member having a first main body and a first latching portion that extends from the main body and through an aperture in a support arm of the first support unit; and
a second coupling member having a second main body and a second latching portion that is latched to the first latching member,
wherein the first main body of the first coupling member and the second coupling member are disposed on opposite sides of the support arm.

3. The shelf assembly according to claim 2 , wherein the second coupling member includes a projection that projects from the second main body into a receiving portion defined by the second support unit.

4. The shelf assembly according to claim 1 , wherein:
the first shelf comprises a glass panel having an upper surface and a lower surface, the upper surface comprising a plurality of edge portions, and
at least one of the plurality of edge portions of the upper surface is exposed.

5. The shelf assembly according to claim 4 , wherein:
the plurality of edge portions of the upper surface includes a front edge portion, a rear edge portion, a left edge portion, and a right edge portion; and
the left edge portion and the right edge portion are exposed.

6. The shelf assembly according to claim 5 , wherein:
the first shelf comprises a front trim member and a rear trim member attached to the glass panel,
the front trim member extends longitudinally along and a front side surface of the glass panel, and
the rear trim member extends longitudinally along a rear side surface of the glass panel.

7. The shelf assembly according to claim 6 , wherein the front trim member extends longitudinally along the entire front side surface of the glass panel and the rear trim member extends longitudinally along the entire rear side surface of the glass panel.

8. The shelf assembly according to claim 7 , wherein the front trim member covers the front edge portion of the glass panel and the rear trim member covers the rear edge portion of the glass panel.

9. The shelf assembly according to claim 8 , wherein:
the left edge portion of the glass panel extends continuously along a major length of an associated left edge of the glass panel; and
the right edge portion of the glass panel extends continuously along a major length of an associated right edge of the glass panel.

10. The shelf assembly according to claim 9 , wherein the right edge portion of the glass panel extends continuously along the associated right edge of the glass panel from the front edge portion to the rear edge portion.

11. The shelf assembly according to claim 6 , wherein the rotating hinge body is fixed at one end to the front trim member and at another end to the rear trim member.

12. The shelf assembly according to claim 4 , wherein:
the upper surface of the glass panel defines an upper side of the glass panel and the lower surface of the glass panel defines a lower side of the glass panel; and
the rotating hinge body is disposed on the lower side of the glass panel.

13. The shelf assembly according to claim 1 , wherein the biasing member biases the cam follower along the rotational axis into engagement with the cam.

14. The shelf assembly according to claim 1 , wherein the cam is fixed to the stationary hinge body and cam follower is slidingly coupled to the rotating hinge body such that the cam follower is slidable relative to the rotating hinge body along the rotational axis.

15. The shelf assembly according to claim 14 , wherein the cam follower is configured to prohibit rotation of the cam follower relative to the rotating hinge body about the rotational axis.

16. The shelf assembly according to claim 1 , wherein the cam and cam follower each include:
a plurality of lobes that are symmetrically spaced about the rotational axis and project axially from a base body; and
a plurality of recesses defined between the plurality of lobes that are symmetrically spaced about the rotational axis.

17. The shelf assembly according to claim 16 , wherein the cam assembly is configured such that when the first shelf is in the first position, the plurality of lobes of the cam follower will circumferentially align with the plurality of recesses of the cam about the rotational axis.

18. The shelf assembly according to claim 17 , wherein the cam assembly is configured such that when the first shelf is in the second position, the plurality of lobes of the cam follower will circumferentially align with the plurality of recesses of the cam about the rotational axis.

19. The shelf assembly according to claim 1 , wherein:
the cam follower comprises a shaft that is coaxial with the rotational axis, and
the biasing member comprises a coil spring that is provided around the shaft of the cam follower.

20. The shelf assembly according to claim 19 , wherein the coil spring is compressed by a head of the cam follower and a wall member of the rotating hinge body such that the coil spring biases the cam follower along the rotational axis into engagement with the cam.
