Patent ID: 7179010

Claim:
An adjustable clamp assembly for securing cylindrical members having variously sized outer diameters and an axial length to an elongate U-shaped support channel, the clamp assembly comprising: a unitary first clamp half formed from plastic having a first end slidably engageable to the support channel, a second end spaced apart from the channel, and an adaptable inner surface for mating engagement with cylindrical members having variously sized outer diameters, the first end including a shoulder region and a narrowed neck region disposed between the adaptable inner surface and the shoulder region; a unitary second clamp half formed from plastic having a corresponding first end slidably engaged to the support channel, a corresponding second end, and an adaptable inner surface for mating engagement with cylindrical members having variously sized outer diameters opposing the first clamp half inner surface, the corresponding first end including a corresponding shoulder region and a corresponding narrowed neck region disposed between the adaptable inner surface and the corresponding shoulder region; an attachment region formed at the second end of each of the first and second clamp halves for coupling the first and second clamp halves together; and a fastener cooperating with the first and second clamp half attachment regions to effectuate fastening engagement between the first and second clamp halves; wherein the adaptable inner surface of each clamp half includes a plurality of grip bumps extending axially along the adaptable inner surface parallel to the axial length of the cylindrical members and projecting radially inward to provide size adjustment capability for cylindrical members having variously sized outer diameters, each set of corresponding grip bumps or combination of grip bumps of the first and second clamp halves defining contact points corresponding to and engageable with a different sized outer diameter of said cylindrical members diameters.
