Mounting device for mounting a small electronic device in a space for a larger electronic device

Claim 1

A mounting device for mounting a first electronic device having a first box shape in a space for a second electronic device having a second box shape which is larger than said first box shape, comprising: a space portion defined as the sum of the distances between outer sides of said first box shape and sides of said second box shape when said first electronic device is mounted in said space; first and second chassis members each having a width equal to half of said space portion; and wherein said first electronic device is mounted to said first and said second chassis members by a plurality of fastening members extending through mounting holes in said first and second chassis members into opposite sides of said first electronic device, and said first and second chassis members having means for mounting said members within said space for said second electronic device; said first and second chassis members each being formed by a respective angle member having a U-shaped cross-section with a pair of vertical wall portions and a horizontal portion connecting said vertical wall portions, an inner one of said vertical wall portions of each chassis member being mounted on a respective side wall of said first electronic device and an outer one of said vertical wall portions of each chassis member being mounted in said space instead of said second electronic device; wherein groove holes are formed at rear portions of the inner vertical wall portions of said first and second chassis members, and a relay substrate is mounted on said first and second chassis members by inserting engaging protrusions formed on both sides of said relay substrate into the groove holes, said relay substrate having a first connector engaged with a connector disposed on a rear plane of said first electronic device and a second connector which is formed in a rear end portion of said relay substrate and is connected with the first connector.
