Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
161 words
A tube protecting device comprising: a clamp support having a first end portion and a second opposite end portion with at least one clamp element attached therebetween for supporting an undersurface of at least one tube, said first end portion being bent to project away from the clamp support; tube protecting means removably attached to said clamp support and having a protection surface for covering at least an undersurface of said at least one tube, said protection surface having a recess portion and an opposite engageable end portion, a spring portion being located adjacent said recess portion for biasing said first end portion of said clamp support into engagement with said recess, and said second end portion of said clamp support into engagement with said engageable end portion of said tube protecting means, said spring portion being integrally formed on said tube protecting means and defined by a tab cut from said protection surface and projecting therefrom toward said clamp support.
Claim 2
Dependent Claim
161 words
A tube protecting device comprising: a clamp support having a first end portion and a second opposite end portion with at least one clamp element attached therebetween for supporting an undersurface of at least one tube, said first end portion being bent to project away from the clamp support; tube protecting means removably attached to said clamp support and having a protection surface for covering at least an undersurface of said at least one tube, said protection surface having a recess portion and an opposite engageable end portion, a spring portion being located adjacent said recess portion for biasing said first end portion of said clamp support into engagement with said recess, and said second end portion of said clamp support into engagement with said engageable end portion of said tube protecting means, said spring portion being integrally formed on said tube protecting means and defined by a tab cut from said protection surface and projecting therefrom toward said clamp support.
Claim 3
Dependent Claim
