Patent ID: 7524154

Claim:
An eccentric fastening device comprising: a first threaded fastener; a base, said base having a top, a bottom, a stem and a hole, said stem axially extending from said bottom and having a first center, and said hole axially extending from said top through said stem and having a second center; and a rotary lug releasably retained in said hole of said base by said first threaded fastener having a non-fastened pre-assembled position, said rotary lug having a cylindrical portion having a thread and a third center, and a head having a forth center, wherein said third center is offset from said forth center, wherein said third center is substantially axially concentric with said second center, and said forth center may be eccentrically rotated about said third center, whereby a selective structure may be variably clamped and releasably retained between said head and said base; wherein said stem of said base has a stem seat for receiving a lug seat on said head in a non-fastened pre-assembled position, a first guide surface and a second guide surface for guiding said head during releasable variable fastening of a selected structure; wherein said head has a first stop surface and a second stop surface respectively engaging said first guide surface and said second guide surface for guiding said head during releasable variable fastening of a selected structure; and wherein said head has a tab extending from said lug seat approximate to said second stop surface, wherein said tab allows for partial eccentric rotation of the lug seat of the rotary lug by engaging the first guide surface of the stem of the base when the lug seat has cleared the stem seat during eccentric rotation of the rotary lug, and said tab in the opposite rotary direction stops the partial eccentric rotation of the lug seat of the rotary lug by engaging the second guide surface of the stem of the base when the lug seat is eccentrically rotated onto the stem seat.
