Claim:
For a component rack having opposing first and second vertical members, a system comprising: a panel sized to extend between the vertical members; a first hinge having a stationary member, a mobile member, a lever member, a first attachment member, and a second attachment member, the stationary member configured to be coupled to the first vertical member, the mobile member configured to be coupled to the panel, the stationary member having a first opening shaped to form a first track including a first position, a second position, and a third position, the stationary member having a second opening to form a second track including a first position, a second position, and a third position, the lever member being coupled to the mobile member through the first attachment member being attached to the lever member and the mobile member and through the second attachment member being attached to the lever member and the mobile member, the first attachment member passing through the first opening, the second attachment member passing through the second opening, the first track and the second track shaped so that when the first attachment member is at the first position of the first track, the second attachment member can go from the first position to the second position of the second track thereby traveling substantially in an arc about the first attachment member while the first attachment member is held in the first position of the first track by the first track and the lever member, the first track and the second track shaped so that when the second attachment member is at the third position of the second track, the first attachment member can go from the second position to the third position of the first track thereby traveling substantially in an arc about the second attachment member while the second attachment member is held in the third position of the second track by the second track and the lever member, and a second hinge having a stationary member, a mobile member, a lever member, a first attachment member, and a second attachment member, the stationary member configured to be coupled to the second vertical member.
