Abstract

Abstract A tube clamp assembly (10) for clamping and supporting a rigid coupling (30) or a flexible elastomeric grommet (32). The tube clamp (10) includes a pair of oppositely facing clamping members (12u, 12l) each having a generally U-shaped cross section with at least one clamping seat (26) and an associated clamping hole (28) for mounting one of the coupling (30) and the grommet (32) between the clamping members (12u, 12l). The tube clamp (10) further includes a set of four arcuate flanges (52f, 52b; 54f, 54b) extending into the clamping hole (28) from the clamping seat (26). The flanges (52f, 52b; 54f, 54b) grip an elastomeric grommet (32) upon application of a predetermined clamping force to prevent removal of the grommet (32) from the tube clamp (10) and yield away from a rigid coupling (30) upon application of the predetermined clamping force to allow the rigid coupling (30) to be fully seated against the clamping seat (26).

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 227 words
A tube clamp assembly (10) of the type for clamping and supporting rigid couplings (30) for fluid lines and flexible elastomeric grommets (32) disposed about a fluid line for reducing shock and vibration, said tube clamp (10) comprising: a pair of oppositely facing clamping members (12u, 12l) each having generally U-shaped cross section defined by a pair of spaced apart side walls (14f, 14b; 16f, 16b) and a connecting wall (18u, 18l) extending therebetween, said side walls (14f, 14b; 16f, 16b) defining at least one clamping seat (26) at distal free ends (22f, 22b; 24f, 24b) of said side walls and a clamping hole (28) for mounting one of the couplings (34) and the grommets (32) between said clamping members (12u, 12l); characterized by including gripping means (50) extending into said clamping hole (28) from only a portion of said clamping seat (26) and leaving a major portion of said clamping seat free of said gripping means for biting into and gripping an elastomeric grommet (32) upon application of a predetermined clamping force to said clamping members (12u, 12l) to prevent sliding movement of the grommet (32) relative to said clamping members (12u, 12l) and for yielding and permanently deforming away from a rigid coupling (30) upon application of the predetermined clamping force to allow the rigid coupling (30) to be seated against said clamping seat (26).
Claim 2
Dependent Claim 227 words
A tube clamp assembly (10) of the type for clamping and supporting rigid couplings (30) for fluid lines and flexible elastomeric grommets (32) disposed about a fluid line for reducing shock and vibration, said tube clamp (10) comprising: a pair of oppositely facing clamping members (12u, 12l) each having generally U-shaped cross section defined by a pair of spaced apart side walls (14f, 14b; 16f, 16b) and a connecting wall (18u, 18l) extending therebetween, said side walls (14f, 14b; 16f, 16b) defining at least one clamping seat (26) at distal free ends (22f, 22b; 24f, 24b) of said side walls and a clamping hole (28) for mounting one of the couplings (34) and the grommets (32) between said clamping members (12u, 12l); characterized by including gripping means (50) extending into said clamping hole (28) from only a portion of said clamping seat (26) and leaving a major portion of said clamping seat free of said gripping means for biting into and gripping an elastomeric grommet (32) upon application of a predetermined clamping force to said clamping members (12u, 12l) to prevent sliding movement of the grommet (32) relative to said clamping members (12u, 12l) and for yielding and permanently deforming away from a rigid coupling (30) upon application of the predetermined clamping force to allow the rigid coupling (30) to be seated against said clamping seat (26).
Claim 3
Dependent Claim 22 words
An assembly as set forth in claim 1 further characterized by said clamping members (12u, 12l) fabricated from an organic polymeric material.
