Abstract: The present invention relates to a support base for cabinets designed to house electrical and/or electronic apparatuses, and a cabinet equipped with such a support base. The support base comprises four corner blocks and four panels joining the corner blocks, the corner blocks each comprising an upper assembly plate and a lower assembly plate assembled to one another by vertical partitions, the upper plate comprising means for fixing the block to the frame of the cabinet, whereas the lower plate comprises means for fixing the block to the ground. These fixing means comprise two fixing orifices accessible respectively via the two external side faces of the block, each orifce having a fixing axis which is inclined by an angle of about 20.degree. with respect to the plane of the corresponding external face of the block. Each block comprises a vertical internal partition forming an angle of 45.degree. with the external faces of the block and comprising an opening for the passage of handling bars.

Abstract: A corner junction for a cabinet, including a gusset plate having two profile sections secured thereto and including two adjacent joining surfaces which extend perpendicularly to a plane of the profile sections. A foot having complementary joining surfaces is secured to the gusset plate, such that the complementary joining surfaces are received by and abut against the joining surfaces of the gusset plate. At least one protruding portion extends from the foot and at least one complementary notch is formed in the gusset plate or the profile sections, the complementary notch receiving the protruding portion to lock the foot from translating in a direction parallel to the longitudinal axis of the foot. Additionally, a securing device is provided to secure the foot to the gusset plate, by clamping the foot between the joining surfaces. The foot is adapted to engage the gusset plate by translation along a direction parallel to the plane of the profile sections.
