View Patent ↗A drum including a cylindrical shell having an upper edge defining an open top end, and a lower edge defining an open bottom end; a drum skin disposed over the top end; a plurality of lugs mounted on an outer surface of the shell in positions annularly spaced adjacent to the bottom end; and a cover movable between a closed position closing the bottom end and an open position providing access into the shell through the bottom end. Also included is a latch mechanism retained by one or more of the lugs and operable to either retain the cover in the closed position or allow movement of the cover into the open position.
1. A drum comprising:
a cylindrical shell having an upper edge defining an open top end, and a lower edge defining an open bottom end;
a drum skin disposed over said top end;
retainer assembly retaining said drum skin over said top end;
a plurality of lugs mounted on an outer surface of said shell in positions annularly spaced adjacent to said bottom end;
a cover movable between a closed position closing said bottom end and an open position providing access into said shell through said bottom end; and
a latch mechanism retained by one or more of said lugs and operable to either retain said cover in said closed position or allow movement of said cover into said open position.
2. A drum according to claim 1 wherein said cover includes a rim portion extending over said lower edge, and said latch mechanism includes a latch element movable into a latched position engaging said rim to prevent movement of said cover into said open position and movable into a release position allowing movement of said cover into said open position.
3. A drum according to claim 2 wherein said latch element comprises a leg portion extending substantially parallel to said shell, and a head portion joined to a bottom end of said leg portion and projecting therefrom toward said shell.
4. A drum according to claim 3 wherein said latch element is biased in said latched position and forceable into said release position.
5. A drum according to claim 4 wherein said head portion defines an upper ramp surface tapered downwardly and inwardly from said leg portion, and said upper surface is disposed in said latched position to engage said rim portion.
6. A drum according to claim 5 wherein said head portion further defines a lower ramp surface tapered upwardly and inwardly from said leg portion, and said lower surface is disposed to be engaged by said rim during movement of said cover into said closed position.
7. A drum according to claim 4 wherein said leg portion of said latch element is formed of a resilient material biasing said latch element in said latched position and allowing flexible movement into said release position.
8. A drum according to claim 7 wherein said head portion defines an upper ramp surface tapered downwardly and inwardly from said leg portion, and said upper surface is disposed in said latch position to engage said rim portion.
9. A drum according to claim 8 wherein said head portion further defines a lower ramp surface tapered upwardly and inwardly from said leg portion, and said lower surface is disposed to be engaged by said rim during movement of said cover into said closed position.
10. A drum according to claim 7 wherein said drum comprises two or more of said lugs which each include a mounting post secured to said shell, and said leg portion defines an aperture receiving said post.
11. A drum according to claim 1 wherein said drum further comprises a tension assembly for maintaining tension on said drum skin, said tension assembly including a tensioning ring and a tensioning rod extending between each of said lugs and said tensioning ring.
12. A drum according to claim 11 wherein said cover includes a rim portion extending over said lower edge, and said latch mechanism includes a latch element movable into a latched position engaging said rim to prevent movement of said cover into said open position and movable into a release position allowing movement of said cover into said open position.
13. A drum according to claim 12 wherein said latch element comprises a leg portion extending substantially parallel to said shell, and a head portion joined to a bottom end of said leg portion and projecting therefrom toward said shell.
14. A drum according to claim 13 wherein said latch element is biased in said latched position and forceable into said release positions.
15. A drum according to claim 14 wherein said head portion defines an upper ramp surface tapered downwardly and inwardly from said leg portion, and said upper surface is disposed in said latched position to engage said rim portion.
16. A drum according to claim 15 wherein said head portion further defines a lower ramp surface tapered upwardly and inwardly from said leg portion, and said lower surface is disposed to be engaged by said rim during movement of said cover into said closed position.
17. A drum according to claim 14 wherein said leg portion of said latch element is formed of a resilient material allowing flexible movement from said biased latched position to said release position.
18. A drum according to claim 17 wherein said latch element is biased in said latched position and forceable into said release position.
19. A drum according to claim 18 wherein said head portion defines an upper ramp surface tapered downwardly and inwardly from said leg portion, and said upper surface is disposed in said latched position to engage said rim portion.
20. A drum according to claim 17 wherein said head portion further defines a lower ramp surface tapered upwardly and inwardly from said leg portion, and said lower surface is disposed to be engaged by said rim during movement of said cover into said closed position.
