Hose clamp and spring liner
View Patent ↗An improved hose clamp having an annular band with an inner face, tensioning means, and an annular spring liner. The spring liner includes an outwardly-projecting circumferential ridge; an inwardly-projecting circumferential ridge on each side of the outwardly-projecting ridge; and a circumferential shoulder near one or both circumferential edge of the spring liner; and at least one shoulder is adapted to abut the inner face.
1. An annular spring liner, for a hose clamp having an inner face, comprising:
an outwardly-projecting circumferential ridge;
an inwardly-projecting circumferential ridge on each side of said outwardly-projecting ridge; and
a circumferential shoulder near an edge of said liner;
wherein said shoulder is adapted to abut said inner face; and wherein said outwardly-projecting ridge does not abut said inner face in the presence of clamp tensioning forces.
2. The spring liner of claim 1 further comprising a circumferential shoulder near each edge of said liner, wherein said shoulders abut said inner face.
3. The spring liner of claim 2 , further comprising on at least one edge a radially outwardly flared flange.
4. The spring liner of claim 2 , further comprising on each circumferential edge a radially outwardly flared flange.
5. An annular circumferentially corrugated spring liner, for a hose clamp having an inner face, comprising:
a central outwardly convex circumferential ridge;
an inwardly convex circumferential ridge on each side of said central ridge; and
a circumferential shoulder near each edge of said liner;
wherein said liner has generally circular shape with overlapping ends;
wherein said shoulders are adapted to abut said inner face; and
wherein said central ridge does not abut said inner face in the presence of clamp tensioning forces.
6. The spring liner of claim 5 , further comprising on at least one edge a radially outwardly flared flange.
7. The spring liner of claim 5 , further comprising on each circumferential edge a radially outwardly flared flange.
8. A hose clamp comprising: an annular band having an inner face, tensioning means, and an annular spring liner, said spring liner comprising:
an outwardly-projecting circumferential ridge;
an inwardly-projecting circumferential ridge on each side of said outwardly-projecting ridge; and
a circumferential shoulder near an edge of said spring liner;
wherein said shoulder is adapted to abut said inner face; and wherein said outwardly-projecting ridge does not abut said inner face in the presence of clamp tensioning forces.
9. The hose clamp of claim 8 further comprising a circumferential shoulder near each edge of said spring liner, wherein said shoulders abut said inner face.
10. The hose clamp of claim 9 , further comprising on at least one edge a radially outwardly flared flange.
11. The hose clamp of claim 9 , further comprising on each circumferential edge a radially outwardly flared flange.
