Abstract

An integrated anti-tip mechanism is provided for aiding prevention of an electronics rack from tipping. The anti-tip mechanism comprises a long portion with a first end and a second end, the first end coupled to a base of the electronics rack and the second end coupled to a first end of a short portion. The first end of the short portion is coupled to the second end of the long portion and a second end of the short portion further coupled to a caster. When deployed, the caster rolls in a same direction as a set of casters beneath the electronics rack. The caster is a predetermined distance off the floor such that the weight of the electronics rack is carried by the set of casters beneath the electronics rack but contact the floor if the electronics rack tips thereby preventing the electronics rack from tipping past a predetermined angle.

First claim

What is claimed is:

1. An integrated anti-tip mechanism for aiding prevention of an electronics rack from tipping, the anti-tip mechanism comprising:
a long portion with a first end and a second end, the first end coupled to a base of the electronics rack and the second end coupled to a first end of a short portion;
the first end of the short portion coupled to the second end of the long portion and a second end of the short portion further coupled to a caster;
the caster, when the anti-tip mechanism is deployed, rolling in a same direction as a set of casters beneath the electronics rack; and
the caster, when the anti-tip mechanism is deployed, being a predetermined distance off the floor such that the weight of the electronics rack is carried by the set of casters beneath the electronics rack but contact the floor if the electronics rack tips thereby preventing the electronics rack from tipping past a predetermined angle.

2. The integrated anti-tip mechanism of claim 1 , wherein the anti-tip mechanism integrated into the base of the electronics rack through an anti-tip mechanism holding channel in which the long portion slides into the channel.

3. The integrated anti-tip mechanism of claim 2 , wherein the anti-tip mechanism is held into a fully retracted position in the anti-tip mechanism holding channel by a latching mechanism.

4. The integrated anti-tip mechanism of claim 2 , wherein the anti-tip mechanism is held into a fully deployed position in the anti-tip mechanism holding channel by a latching mechanism.

5. The integrated anti-tip mechanism of claim 2 , wherein the anti-tip mechanism is held into a fully deployed position in the anti-tip mechanism holding channel by a bracing mechanism that braces the anti-tip mechanism to a side of the electronics rack.

6. The integrated anti-tip mechanism of claim 1 , wherein the anti-tip mechanism is integrated into the base of the electronics rack via a pivot mechanism.

7. The integrated anti-tip mechanism of claim 6 , wherein the anti-tip mechanism is held into a fully retracted position parallel to a side of the base of the electronics rack by a latching mechanism.

8. The integrated anti-tip mechanism of claim 6 , wherein the anti-tip mechanism is held into a fully deployed position perpendicular to a side of the base of the electronics rack by a bracing mechanism that braces the anti-tip mechanism to a side of the electronics rack.

9. The integrated anti-tip mechanism of claim 1 , wherein the anti-tip mechanism is integrated into a base of the electronics rack at a position in close proximity to the set of casters beneath the electronics rack so as to not impede movement of the electronics rack.

10. An electronics rack comprising an anti-tip mechanism for aiding prevention of the electronics rack from tipping, the electronics rack comprising:
a base with one or more integrated anti-tip mechanisms, each integrated anti-tip mechanism in the one or more integrated anti-tip mechanisms comprising:
a long portion with a first end and a second end, the first end coupled to a base of the electronics rack and the second end coupled to a first end of a short portion:
the first end of the short portion coupled to the second end of the long portion and a second end of the short portion further coupled to a caster;
the caster, when the integrated anti-tip mechanism is deployed, rolling in a same direction as a set of casters beneath the electronics rack; and
the caster, when the integrated anti-tip mechanism is deployed, being a predetermined distance off the floor such that the weight of the electronics rack is carried by the set of casters beneath the electronics rack but contact the floor if the electronics rack tips thereby preventing the electronics rack from tipping past a predetermined angle.

11. The electronics rack of claim 10 , wherein the integrated anti-tip mechanism integrated into the base of the electronics rack through an integrated anti-tip mechanism holding channel in which the long portion slides into the channel.

12. The electronics rack of claim 11 , wherein the integrated anti-tip mechanism is held into a fully retracted position in the integrated anti-tip mechanism holding channel by a latching mechanism.

13. The electronics rack of claim 11 , wherein the integrated anti-tip mechanism is held into a fully deployed position in the integrated anti-tip mechanism holding channel by a latching mechanism.

14. The electronics rack of claim 11 , wherein the integrated anti-tip mechanism is held into a fully deployed position in the integrated anti-tip mechanism holding channel by a bracing mechanism that braces the integrated anti-tip mechanism to a side of the electronics rack.

15. The electronics rack of claim 10 , wherein the integrated anti-tip mechanism integrates into the base of the electronics rack via a pivot mechanism.

16. The electronics rack of claim 15 , wherein the integrated anti-tip mechanism is held into a fully retracted position parallel to a side of the base of the electronics rack by a latching mechanism.

17. The electronics rack of claim 15 , wherein the integrated anti-tip mechanism is held into a fully deployed position perpendicular to a side of the base of the electronics rack by a bracing mechanism that braces the integrated anti-tip mechanism to a side of the electronics rack.

18. The electronics rack of claim 10 , wherein the integrated anti-tip mechanism is integrated into the base of the electronics rack at a position in close proximity to the set of casters beneath the electronics rack so as to not impede movement of the electronics rack.

19. The electronics rack of claim 10 , wherein the one or more integrated anti-tip mechanisms is two sets of integrated anti-tip mechanisms, wherein a first set of the two sets of integrated anti-tip mechanisms is located at the front of the electronics rack and deploys to the sides of the electronics rack and a second set of the two sets of integrated anti-tip mechanisms is located at the back of the electronics rack and deploys to the sides of the electronics rack.

20. The electronics rack of claim 10 , wherein the one or more integrated anti-tip mechanisms is four sets of integrated anti-tip mechanisms, wherein a first set of the four sets of integrated anti-tip mechanisms is located at the front of the electronics rack and deploys to the sides of the electronics rack, a second set of the four sets of integrated anti-tip mechanisms is located at the back of the electronics rack and deploys to the sides of the electronics rack, a third set of the four sets of integrated anti-tip mechanisms is located to the left of the electronics rack and deploys to a front and a back of the electronics rack, and a fourth set of the four sets of integrated anti-tip mechanisms is located to the right of the electronics rack and deploys to the front and the back of the electronics rack.
