| Title of Invention | "SELF- ADJUSTING AT - LEAST- TWICE- ORIENTED POLYMER HOSE AND TUBING CLAMP" |
|---|---|
| Abstract | An oriented polymer type hose clamp which is characterised by said hose clamp having a shrinkage response to each of at least two diameter reducing release temperatures. |
| Full Text | WE CLAIM: 1. A hose clamp comprising hose clamp for providing a clamping force about connection ends of elastomeric hose and stems associated with automotive coolant systems; said hose being formed of an at-least-twice- oriented polymer in the form of a band, each of said at least two diameter reducing release temperatures being within the range of from about - 40°C to about 175°C, said band being sized and formed to be radially disposed about said connection end of said hose to urge said hose toward tight and sealing engagement with said stem and to resist axial movement of said hose relative to said stem. 2. An oriented polymer type hose clamp as claimed in claim 1, wherein said hose clamp having a shrinkage response to each of at least two diameter reducing release temperatures. 3. A hose clamp as claimed in claim 2, wherein said at least two diameter reducing release temperatures are within the range of from about -40°C to about 175°C. 4. A hose clamp as claimed in claim 3, wherein said at least two diameter reducing release temperatures are variably preselected. 5. A hose clamp as claimed in claim 4, wherein said release temperature preselection is effected by selecting polymer orientation temperatures. 6. A hose clamp as claimed in claim 4, wherein each of said diameter reducing release temperatures is variably preselected to be at least about 5°C different from any other diameter reducing temperature. 7. A hose clamp as claimed in claim 1, wherein said band has a first diameter reducing release temperature within the range of from about 0°C to about 40°C, and a second diameter reducing release temperature within the range of from about 0°C to about 150°C. 8. A hose clamp as claimed in claim 1, wherein said band has a first diameter reducing release temperature within the range of from about 10°C to about 30°C, and a second diameter reducing release temperature within the range 0 f from about 15°C to about 100°C. 9. An oriented polymer type hose clamp substantially as hereinbefore described with reference to the accompanying drawings. |
