Abstract

A rack for mounting communication apparatuses or similar electronic apparatuses. The rack has a pair of posts symmetrical to each other in the right-and-left direction and each having a section in the form of a letter C. The posts are positioned such that the open side of "C" faces outward. A shelf included in an electronic apparatus is mounted to the posts. The posts are tied to each other by a top frame at upper ends and affixed to a base at lower ends. A generally L-shaped reinforcing member is connected to the lower portion of each post such that the longer side of "L" is parallel to the closed side of "C" representing the post, thereby providing the lower portion of the post with a hollow rectangular section. The reinforcing member is not connected to the base.

Claims

1. An independent rack for mounting electronic apparatuses, comprising:

a pair of cable duct posts with a mirror image symmetry in a right-and-left direction when said rack is seen from the front, and each of said posts having a cross-section substantially in a form of a letter "C" and being arranged such that an open side of said "C" faces outwardly to receive cables;

a top frame tying upper ends of said pair of posts;

a base to which lower ends of said pair of posts are affixed; and

means at a lower portion of each of said pair of posts adjoining said base for closing said open side of said "C" in order to form a hollow rectangular section,

wherein said means comprises a pair of reinforcing members having a section in a form of a letter "L" and respectively affixed to said lower portions of said pair of posts such that a longer arm of said "L" is parallel to and closes the open side of said "C", for completing the hollow rectangular section of the post, said pair of reinforcing members being not connected to said base.

2. An independent rack for mounting electronic apparatuses, comprising:

a pair of cable duct posts with a mirror image symmetry in a right-and-left direction when said rack is seen from the front, and each of said posts having a cross-section substantially in a form of a letter "C" and being arranged such that an open side of said "C" faces outwardly to receive cables;

a top frame tying upper ends of said pair of posts;

a base to which lower ends of said pair of posts are affixed; and

means at a lower portion of each of said pair of posts adjoining said base for closing said open side of said "C" in order to form a hollow rectangular section,

wherein said means comprises a pair of reinforcing members having a generally "T"-shape as seen from the front and each being positioned such that a leg of said "T" is parallel to a direction of a height of the post, opposite arms of said "T" being connected to opposite open ends of said "C", representing said post, said leg being affixed to said base at a bottom thereof and spaced apart from said base at lower opposite sides thereof.
