Abstract
A clamping apparatus for a hose or another suitable tubular member. A coiled band forms an opening within which the hose or other tubular member is positioned. The coiled band forms an inner band, a middle band and a outer band. The middle band is sandwiched between the inner band and the outer band. A retainer is positioned about the inner band and the outer band, to retain the inner band, the middle and the outer band in a sandwiched position with respect to each other. Two or more projections extend radially inward, toward the opening formed by the coiled band, from the inner band. The projections interfere with the retainer to limit movement of the retainer in two directions, opposite to each other, along a longitudinal axis of the band.
Claims19
A clamping apparatus comprising:
- a coiled band forming an inner band, a middle band and an outer band;
- a retainer positioned adjacent said inner band and positioned adjacent said outer band;
- and
- an inner surface of said inner band having a plurality of projections each directed radially inward, each of said projections projecting far enough away from said inner surface to form a bearing surface that can abut said retainer, a first projection of said projections positioned on a first side of said retainer and a second projection of said projections positioned on a second side of said retainer.
A clamping apparatus comprising:
- a coiled band forming an inner band, a middle band and an outer band;
- a retainer positioned adjacent said inner band and positioned adjacent said outer band;
- an inner surface of said inner band having a plurality of projections each directed radially inward, a first projection of said projections positioned on a first side of said retainer and a second projection of said projections positioned on a second side of said retainer;
- and
- at least two of said projections each comprising a dimple in said inner band, said dimple indented from a first surface of said inner band, said first surface facing radially outward, and said projection projecting radially inward beyond a second surface of said inner band, and said second surface being opposite said first surface.
A clamping apparatus comprising:
- a coiled band forming an inner band, a middle band and an outer band;
- a retainer positioned adjacent said inner band and positioned adjacent said outer band;
- an inner surface of said inner band having a plurality of projections each directed radially inward, a first projection of said projections positioned on a first side of said retainer and a second projection of said projections positioned on a second side of said retainer;
- and
- each of said projections having a bearing surface and extending radially inward far enough for said bearing surface to bear against said retainer when said retainer is moved toward said projection and for said bearing surface to prevent said retainer from moving beyond said projection.
A clamping apparatus comprising:
- a coiled band forming an inner band, a middle band and an outer band;
- a retainer retaining said middle band in a sandwiched position between said inner band and said outer band;
- and
- an inner surface of said inner band having a plurality of projections each directed radially inward, each of said projections projecting far enough away from said inner surface to form a bearing surface that can abut said retainer, and said projections limiting movement of said retainer along a longitudinal axis of said band.
A clamping apparatus comprising:
- a coiled band forming an inner band, a middle band and an outer band;
- a retainer positioned about said inner band and said outer band and retaining said inner band, said middle band and said outer band in a sandwiched position with respect to each other;
- and
- a plurality of projections directed radially inward from said inner band, each of said projections projecting far enough away from said inner surface to form a bearing surface that can abut said retainer, and said projections interfering with said retainer to limit movement of said retainer in two directions opposite each other and along a longitudinal axis of said band.
