Adjustable pipe clamp assembly
View Patent ↗An adjustable clamp assembly capable of securing various sized cylindrical members is generally formed from a high strength plastic material dispensing the need for a cushion insert for the cylindrical member disposed therebetween. The clamp assembly contains a pair of unitary clamp halves having an inner surface contoured to adequately contact the surface of various sized cylindrical members to provide support when clamping forces are applied. The clamp halves can be interlockingly engageable with one another to enhance the cylindrical member size adjustment capability.
1. 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.
2. The adjustable clamp assembly of claim 1 , wherein the first clamp half and the second clamp half are adapted to cooperate with the support channel for securing cylindrical members having variously sized outer diameters thereto such that at least one of the plurality of grip bumps of the first clamp half and at least one of the plurality of grip bumps of the second clamp half makes direct contact with the cylindrical members having variously sized outer diameters.
3. 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 first clamp half having a first end slidably engageable with the support channel along a channel axis, a second end spaced apart from the channel, and an adaptable inner surface having a plurality of transverse, axially extending grip bumps extending parallel to the axial length of the cylindrical members and projecting radially inward for mating engagement with cylindrical members having variously sized outer diameters; and
a second clamp half having a corresponding first end slidably engageable with the support channel along the channel axis, a corresponding second end, and an adaptable inner surface opposing the first clamp half inner surface having a plurality of transverse, axially extending grip bumps extending parallel to the axial length of the cylindrical members and projecting radially inward for mating engagement with 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 each clamp half having an attachment region formed at the second end for coupling the first and second clamp halves together.
4. The adjustable clamp assembly of claim 3 , having at least two contact points for securing cylindrical members having variously sized standard outer diameters to the support channel, the at least two contact points including the at least one of the plurality of grip bumps of the first clamp half and the at least one of the plurality of grip bumps of the second clamp half.
5. The adjustable clamp assembly of claim 3 , wherein the first end of each clamp half includes a narrowed neck region and a shoulder region for cooperating with the support channel to effectuate sliding engagement.
6. The adjustable clamp assembly of claim 3 , wherein the attachment region of each clamp half comprises an aperture for at least partially inserting a fastener therethrough to couple the first clamp half to the second clamp half.
7. The adjustable clamp assembly of claim 6 , wherein the fastener comprises a nut and bolt assembly.
8. The adjustable clamp assembly of claim 6 , wherein the first clamp half aperture includes a boss for housing a nut, the boss having a detent formed therein for snap fit retention of the nut, the second clamp half aperture having a finger for retaining a bolt.
