View Patent ↗The method of drum structure formation that includes forming a strip of metal having an elongated edge into a counter hoop to be supported by a drum shell proximate the drum head, the forming including forming a reduced thickness strip bend proximate the hoop edge area.
1. A method for forming a drum hoop, said method comprising:
forming a strip of metal comprising an elongated edge into a hoop;
forming a portion of said strip of metal into a thinned portion; and
forming said elongated edge into a rolled bend.
2. The method of claim 1 , wherein said forming of said thinned portion comprises milling said elongated edge to form said thinned portion.
3. The method of claim 1 , wherein said rolled bend extends downwardly.
4. The method of claim 1 , wherein said rolled bend is arcuate.
5. The method of claim 1 , wherein said elongated edge comprises said thinned portion.
6. The method of claim 1 , wherein forming said rolled bend comprises forming at least a portion of said thinned portion into at least a portion of said rolled bend.
7. The method of claim 1 , wherein said rolled bend is rolled toward the outer side of the hoop.
8. The method of claim 6 , wherein said thinned portion is milled.
9. The method of claim 1 , wherein said forming of said thinned portion comprises milling.
10. A drum hoop comprising a wall shaped to define a hoop, wherein said wall is shaped to define a rolled edge portion; and
wherein said rolled edge portion comprises a first portion thinner than the rest of said wall.
11. The drum hoop of claim 10 , wherein said rolled edge portion is rolled toward the outside of said hoop.
12. The drum hoop of claim 10 , wherein said rolled edge portion extends downwardly.
13. The drum hoop of claim 10 , wherein said rolled edge portion extends vertically downward or past vertically downward.
14. The drum hoop of claim 10 , wherein said rolled edge portion comprises an upper arcuate surface.
15. The drum hoop of claim 10 , wherein said drum hoop is shaped to fit on a drum head.
16. The drum hoop of claim 15 , wherein said drum hoop is configured to engage said drum head.
17. The drum hoop of claim 10 , further comprising one or more sideward projections spaced from said rolled edge portion and shaped to define an opening for a drum tensioning rod.
18. The drum hoop of claim 10 , wherein said drum hoop is shaped to define a seating edge for engagement with a drum head or drum shell.
19. A method for forming a drum hoop, said method comprising:
milling an elongated edge of a strip of metal;
forming said strip of metal into a hoop; and
forming said elongated edge into a rolled bend.
20. The method of claim 19 , wherein said rolled bend is rolled toward the outer side of said hoop.
21. The method of claim 19 , wherein said rolled bend extends downwardly.
22. The method of claim 19 , wherein said rolled bend extends vertically downward or past vertically downward.
23. The method of claim 19 , wherein said milled elongated edge is thinner than the rest of said strip of metal.
24. The method of claim 19 , wherein said rolled bend is arcuate.
25. The method of claim 1 , further comprising forming one or more sideward projections spaced from said rolled edge portion and shaped to define an opening for a drum tensioning rod.
