Safety apparatus for electrical equipment rack
First Claim
1. A safety apparatus for an electrical equipment rack, the rack comprising a frame comprising mounting arrangements for extendable rails for mounting electrical equipment units, the extendable rails allowing the electrical equipment units to be extended on the extendable rails from a position internal to the rack to a position external to the rack, and the rack further comprising casters for supporting a base of the rack during movement of the rack over a surface, and retractable rack supports which when extended from raised inoperative positions to lowered operative positions support the rack on the surface, the safety apparatus comprising:
- a retractable safety device for preventing, when in an operational position, the extending of one of said extendable rails and one of said electrical equipment units mounted on the extendable rail from a position internal to the rack to a position external to the rack, and for allowing the extending of the extendable rail and the electrical equipment unit mounted on the extendable rail when in a non-operational position, the position of the retractable safety device being linked to the position of one of said retractable rack supports such that;
when the retractable rack support is lowered in the lowered operative position to support the rack, the retractable safety device is in the non-operational position; and
when the retractable rack support is raised in the raised inoperative position the retractable safety device is in the operational position preventing the extending of the extendable rail and the electrical equipment unit mounted on the extendable rail to a position external to the rack.

Abstract
A safety apparatus for an electrical equipment rack includes a retractable safety device for preventing, when in an operational position, the extending of an extendable rail and an electrical equipment unit mounted thereon from a position internal to the rack to a position external to the rack, and for allowing the same when in a non-operational position. The position of the retractable safety device is linked to the position of a retractable rack support such that when the retractable rack support is lowered in its operative position the retractable safety device is in a non-operational position, and when it is raised in a raised inoperative position the retractable safety device is in an operational position preventing the extending of the extendable rail and an electrical equipment unit mounted thereon to a position external to the rack.
