US Patent 8985345 Rack for electronic apparatus

A rack includes a rack body, at least one latch member secured to the rack body, and a supporting assembly. The supporting assembly includes at least one sliding lever and a supporting member secured to the at least one sliding lever. The at least one sliding lever is slidably engaged in the at least one latch member and the supporting assembly is extendable and retractable relative to the rack body, to provide a wider base for the rack when required where it rests on the floor, increasing stability and decreasing the likelihood that the rack might topple.
