DETAILED DESCRIPTION OF THE INVENTION

(16) With reference now to the drawings, and in particular to FIGS. 1-7 thereof, the preferred embodiment of the new and improved snare drum throw off system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

(17) The present invention, the snare drum throw off system is comprised of a plurality of components. Such components are individually configured and correlated with respect to each other to attain the desired objective. In their broadest context, such invention is a system for use with a snare drum having a throw off component with a fixed end and a repositionable end.

(18) An activating/inactivating assembly is coupled adjacent to a side wall of the drum adjacent to the repositionable end of the throw off component. The activating/inactivating includes a handle operatively coupled to the throw off component. Rotating the handle in a first direction will tighten the throw off component to an operative orientation. Rotating the handle in a second direction will loosen the throw off component to an inoperative orientation.

(19) An adjustable tensioning assembly includes a tensioning bolt having a head and a threaded end coupled with respect to the throw off component. Rotating the knurled head in a first direction will adjustably tighten the throw off component. Rotating the knurled head in a second direction will adjustably loosen the throw off component.

(20) The preferred embodiment of the present invention is illustrated in FIGS. 1-7. From a specific point of viewpoint, the present invention is a snare drum throw off system 10 for supporting and engaging and disengaging a snare 12 of a drum 14, for activating/inactivating the throw off component tensioning the throw off component and its tone.

(21) The supporting and the activating/inactivating and the adjustably tensioning being done in a safe, convenient, and economical manner. The system includes the drum 14 having a top and a bottom with a cylindrical side wall 18 there between and a chamber there within.

(22) Next provided is the snare 12. Such component has a fixed end positioned within the chamber with a strap 22 extending to exterior of the chamber and a central extent diametrically positioned within the chamber. The activation/inactivating assembly 28 is coupled to the side wall of the drum adjacent to the repositionable end of the throw off component. The activation/inactivating assembly includes a mounting bracket 30 having opposed facing walls 32 with a fixed guidepost 34 between the facing walls. Attachment members 36 couple the mounting bracket to the drum. Two pivot posts 38 are parallel with but spaced above the guidepost.

(23) The activating/inactivating assembly includes a handle 40 formed with a central section 42 in an inverted U-shaped configuration and with two parallel linear sections 44 terminating in free ends. The free ends attached to the pivot posts by bolts. A strip clamp 48 and an adjustment pull 50 are secured to the linear section. A coil spring 52 urges separation between the strap and the adjustment. The strap is wrapped around the guidepost and attached to the strap clamp. Rotating the handle in a first direction will tighten the throw off component to an operative orientation. Rotating the handle in a second direction will loosen the throw off component to an inoperative orientation.

(24) Lastly provided tensioning assembly 56 which includes a tensioning bolt 58 having a knurled head 60 and a threaded end 62. The tensioning bolt extends through the adjustment guide and is threadedly coupled to the pull strap. Rotating the knurled head in a first direction will adjustably tighten the throw off component and its tone. Rotating the knurled head in a second direction will adjustably loosen the throw off component and its tone.

(25) An alternate embodiment of the present invention is illustrated in FIGS. 8-13. From a specific point of viewpoint, the invention is a snare drum throw off system 100 for engaging and disengaging a snare 112 of drum 114, for activating/inactivating a drum snare, and for adjustable tensioning the snare and the related tone of the drum. The supporting and the activating/inactivating and the adjustably tensioning are done in a safe, convenient, and economical manner, the system includes the drum 114 having a top and a bottom with a cylindrical side wall 118 there between and a chamber therewithin.

(26) Provided next is snare 112 having a fixed end positioned within the chamber and a repositionable end with 122 positioned within the chamber. Next, an activating/inactivating 128 assembly is coupled to the side wall of the drum adjacent to the repositionable end of the snare. The activating/inactivating assembly 128 includes a pivot block 130. The pivot block has an upper extent 132 attached to the end support and a lower extent 134 with an axis of rotation and a central extent 136. Fixed blades 138 are with the chamber attached to the side wall and pivotably supporting the lower end of the pivot block.

(27) The activating/inactivating assembly 128 includes a minor cylinder 140 with a threaded interior end 142 within the chamber and a cam surface 144 with a recess 146 exterior of the chamber. A nut 148 is on the threaded interior end attaching the minor cylinder to the side wall. A coil spring 150 urges the pivot block away from the nut.

(28) The activating/inactivating assembly 128 includes a major cylinder 154 with an extended interior section terminating adjacent to the pivot block. The major cylinder has a free section 156. The major cylinder has an intermediate section with a cam surface 158 with a projection 160 exterior of the chamber. The major cylinder includes a handle 164 for rotating the major cylinder in a first direction with the projection outside of the recess and the throw off component moving to an inoperative orientation. The handle is also for rotating the major cylinder in a second direction with the projection within the recess and the throw off component moving to an operative orientation.

(29) Lastly provided, an adjustable tensioning assembly 168 includes a shaft 170 with a threaded end 172 and a knurled head 174. The shaft extends through the major cylinder and the minor cylinder and the coil spring and is threadedly coupled to the central section of the pivot block. Rotating the knurled head in a first direction will adjustably loosen the throw off component and vary the tone. Rotating the knurled head in a second direction will adjustably loosen the throw off component and vary the tone.

(30) While the invention herein disclosed has been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the following claims.
