Computer enclosure with height-adjusting feet

Abstract

A computer enclosure includes an enclosure base, an enclosure cover, two pivoting rods or axles, two height-adjusting feet, pushing members, and two connecting poles. The enclosure cover pivots on the enclosure base and the pivoting axles are connected to the enclosure base and pivot with the enclosure cover. The pivoting axles are not circular but present lobes or cams at a certain angle. The connecting poles are connected to the pivoting axles and the pushing members, the pushing members are fixed on the enclosure base and connected to the height-adjusting feet. Rotating the cover up and away from the enclosure base causes the lobes of the pivoting axles to lift and thus bear down on the height-adjusting feet, extending them through the enclosure base to take the weight of the computer and provide a larger space for the movement of cooling air underneath the computer.

         5 . The computer enclosure of  claim 3 , further comprising a protrusion block protrudes from the second pivoting portion; when the enclosure cover is rotated away from the enclosure base, the pivoting axis rotates together with the enclosure cover, and the pivoting axis lifts up the first terminal of the connecting pole by the protrusion block. 
     
     
         6 . The computer enclosure of  claim 1 , wherein the connecting pole comprises a first connecting portion and a second connecting portion extending from the first connecting portion; two third pivoting portions protruding from the first connecting portion; two second supporting portions extending from the enclosure base; a pivoting hole being defined in each of the two second supporting portions; each of the two third pivoting portions being configured to be passed through the pivoting hole; a first terminal of the first connecting portion resisting against the second pivoting portion; a first mounting portion extending from the second connecting portion; a first mounting hole being defined in a first terminal of the pushing member; and the first mounting portion being configured to be passed through the first mounting hole. 
     
     
         7 . The computer enclosure of  claim 6 , wherein the pushing member further comprises a second mounting hole defined in a second terminal of the pushing member; a first supporting portion extending from the adjusting feet; a second mounting portion extending from the first supporting portion; and the second mounting portion being configured to be passed through the second mounting hole. 
     
     
         8 . The computer enclosure of  claim 7 , wherein a aperture of the first mounting hole is equal to a diameter of the first mounting portion; a aperture of the second mounting hole is equal to a diameter of the second mounting portion; and a diameter of the third pivoting portion is equal to a aperture of the pivoting hole. 
     
     
         9 . The computer enclosure of  claim 1 , wherein the enclosure base further comprises an accommodating hole to receive the adjusting feet; and the adjusting feet extending out of the enclosure base from the accommodating hole. 
     
     
         10 . The computer enclosure of  claim 9 , wherein a diameter of the adjusting feet is equal to a aperture of the accommodating hole. 
     
     
         11 . A computer enclosure, comprising:
