Floating time bar

1. A drawer assembly for an enclosure including a first interior surface and a second interior surface, the interior surfaces being opposite one another, the drawer assembly including:

a first rack and a second rack mounted near the first interior surface and the second interior surface respectively, each of the racks including a first set of teeth provided longitudinally therealong;

a drawer configured to be movable in and out of the enclosure and including a first face disposed near the first interior surface and a second face disposed near the second interior surface, the drawer including a first pinion and a second pinion rotatably coupled near the first face and the second face respectively, each of the pinions including a second set of teeth provided circumferentially, the first pinion and the second pinion configured to rotate along the first rack and the second rack respectively through engagement of the second set of teeth with the first set of teeth; and

a timing bar including a first end and a second end, the first end and the second end coupled to the first pinion and the second pinion respectively so that the first and second pinions rotate as one, the first end of the timing bar including a sidewall and a slit extending from the first end and through the sidewall and along a longitudinal axis of the timing bar, and

the first pinion including a neck portion and an elongate protrusion formed at a surface of the first pinion, the neck portion is configured to be inserted into the timing bar and the protrusion is configured to be inserted into the slit to extend through the sidewall of the timing bar and be movable about the slit so that the first pinion is movable with respect to the timing bar along the longitudinal axis of the timing bar, and the second pinion is fixedly mounted to the timing bar.

2. The drawer assembly of claim 1 , each of the pinions including a neck portion, the timing bar configured to engage the neck portions.

3. The drawer assembly of claim 1 , the protrusion having a T-shaped cross-section.

4. The drawer assembly of claim 2 , the second end of the timing bar including a first screw hole, the second pinion including a second screw hole extending through the neck portion, the first screw hole and the second screw hole configured to accommodate a screw to fixedly mount the second pinion to the timing bar.

5. The drawer assembly of claim 2 , the timing bar having a U-shaped cross-section configured to at least partially surround the neck portion.

6. The drawer assembly of claim 1 , wherein the enclosure is a refrigerated space.

7. A rack-and-pinion mechanism, including:

a first rack and a second rack, each of the racks including a first set of teeth provided longitudinally therealong;

a first pinion and a second pinion, each of the pinions including a second set of teeth provided circumferentially therearound, the first pinion and the second pinion configured to rotate along the first rack and the second rack respectively through engagement of the second set of teeth with the first set of teeth; and

a timing bar including a first end movably mounted to the first pinion and a second end fixedly mounted to the second pinion, the first end and the second end coupled to the first pinion and the second pinion respectively so that the first and second pinions rotate as one, the first end of the timing bar including a sidewall and a slit extending from the first end and through the sidewall and along a longitudinal axis of the timing bar, the first pinion including a neck portion and an elongate protrusion formed at a surface of the first pinion, the neck portion is configured to be inserted into the timing bar and the protrusion is configured to be inserted into the slit to extend through the sidewall of the timing bar and be movable about the slit, wherein the timing bar includes the slit for receiving the protrusion only on the first end of the timing bar, the first pinion configured to be movable with respect to the timing bar along the longitudinal axis of the timing bar and the second pinion configured to be fixed with respect to the timing bar along the longitudinal axis of the timing bar.

8. The mechanism of claim 7 , each of the pinions including a neck portion, the timing bar configured to engage the neck portions.

9. The mechanism of claim 7 , the protrusion having a T-shaped cross-section.

10. The mechanism of claim 8 , the second end of the timing bar including a first screw hole, the second pinion including a second screw hole extending through the neck portion, the first screw hole and the second screw hole configured to accommodate a screw to fixedly mount the second pinion to the timing bar.

11. The mechanism of claim 8 , the timing bar having a U-shaped cross-section configured to at least partially surround the neck portion.

12. The mechanism of claim 7 , wherein the protrusion is formed as a separate piece of the neck portion.
