Abstract
An improved hose clamp having an annular band having an inner face, tensioning means, and an annular spring liner; the spring liner having a circumferential shoulder near an edge of the liner; and a central, cylindrical, flat, contact portion of smaller circumference than the shoulder, and of smaller width than the inner face of the band. The shoulder is adapted to abut the inner face and the contact portion is adapted to contact a hose or other article to be clamped.
Claims19
An annular spring liner, for a hose clamp having an inner face, comprising:
- a first circumferential shoulder near a first edge of said liner;
- a second circumferential shoulder near a second edge of said liner;
- a first leg extending inwardly in a first direction from a first end attached to said first circumferential shoulder to a second end;
- a second leg extending inwardly in a first direction from a first end attached to said second circumferential shoulder to a second end;
- and
- a central, cylindrical, flat contact portion extending from said second end of said first leg to said second end of said second leg, the contact portion being of smaller circumference than said shoulders,
- wherein (i) said shoulder is adapted to abut said inner face of the hose clamp, and (ii) said first leg and said second leg are moveable elastically between a first position in which said contact portion is spaced apart from said inner face of the hose clamp, a second position in which said contact portion abuts said inner face, and a third position in which said contact portion is spaced apart from said inner face of the hose clamp, said first leg and said second leg being moveable from the second position to the third position.
A hose clamp having an inner face and an annular spring liner, said liner comprising:
- a first circumferential shoulder near a first edge of said liner;
- a second circumferential shoulder near a second edge of said liner;
- a first leg extending inwardly in a first direction from a first end attached to said first circumferential shoulder to a second end;
- a second leg extending inwardly in a first direction from a first end attached to said second circumferential shoulder to a second end;
- and
- a central, cylindrical, flat contact portion extending from said second end of said first leg to said second end of said second leg, the contact portion being of smaller circumference than said shoulders,
- wherein (i) said shoulder abuts said inner face of the hose clamp, (ii) a gap is defined between said contact portion and said inner face of the hose clamp, and (iii) said first leg and said second leg are moveable elastically between a first position in which the gap has a first length, a second position in which the gap has a second length less than the first length, and a third position in which the gap has a third length greater than the second length, said contact portion being moveable from the second position to the third position.
