Abstract:
A drum adjustment apparatus (60) is disclosed which retains a drum key (50) on the clothes of a user for ready access in adjusting the tension of drum heads. An envelope (64) mounts the drum key to a rotatable yoke (72) of a spring loaded snap (80) which may be attached to a belt loop of the user and left there while making fine drum head tuning adjustments.

Description:
FIELD OF THE INVENTION 
     The present invention relates generally to drums and more particularly to apparatus for the adjustment thereof. 
     BACKGROUND OF THE INVENTION 
     Modern drums typically have a drumhead attached to an annular collar which may be moved relative the drum shell to adjust the tension of the drumhead. Musicians adjust this tension with a drum key to obtain the sound they desire. Drum keys are small and easily misplaced. Because the drum adjustments are made frequently, significant time could be saved if the drum key were made readily available to the musician while at work. 
     SUMMARY OF THE INVENTION 
     The present invention is directed to apparatus for retaining a drum adjustment key on a user thereof for ready access thereto. 
     Apparatus in accordance with the invention are characterized by structure for rotatably attaching the drum key to the clothes of the user while exposing the drum key end for engagement with the tension rods of a drum. 
     In a preferred embodiment an envelope encloses the drum key and is retained on a rotatable yoke of a spring loaded snap which may attach to a belt loop of the user. Thus the drum key is retained for ready access and may be employed in adjusting tension rods without removal from the user&#39;s clothes. 
     The novel features of the invention are set forth with particularity in the appended claims. The invention will be best understood from the following description when read in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION 
     FIG. 1 is a perspective view of a typical modern drum 20 having a pair of drumheads 22 (only one drumhead is visible). FIG. 2 is an enlarged view of the area within the line 2 of FIG. 1 illustrating typical drum apparatus for adjusting the drumhead tension while FIG. 3 is a sectional view along the plane 3--3 of FIG. 2. 
     FIGS. 2 and 3 show that the drumhead 22 is attached (e.g. by epoxy) to an annular collar 24 that fits about the drum shell 26. A rim 28 is configured to abut the collar 24 while also being spaced from the edge of the shell 26. The rim 28 is bent locally to form a lip 30 to receive a tension rod 32 which terminates in a square shaft 33. The tension rod 32 defines an annular skirt 34 that abuts the lip 30. The tension rod 32 is threadably received in a boss 36 mounted to the shell 26. Thus turning the tension rod 32 moves the rim 28 and collar 24 relative to the shell 26 to adjust the tension of the drumhead 22. 
     Musicians frequently adjust, in sequence, the tension rods 32 surrounding the drum shell 26 to obtain a desired tone. This adjustment is typically effected by using a drum key 40 as illustrated in the front elevation view of FIG. 4. The drum key 40 is also shown in the side elevation view of FIG. 5 and the bottom plan view of FIG. 6. 
     The drum key 40 has a flat handle 42 and an end 44 defining a substantially square recess 46 which can be placed over the square shaft 33 of the tension rod 32 (as shown in FIGS. 2, 3). Some drums have tension rods that terminate in a slotted head. FIGS. 7 and 8 are, respectively, front elevation and side elevation views of another drum key end 44&#39; configured as a flat blade 48 to mate with such tension rods. 
     As stated above, the tone of a drum is frequently adjusted and, often, a musician plays a drum set which involves a multiplicity of such adjustments. The drum key is thus an important tool to which the musician requires ready access. Unfortunately, the drum key is also a small tool that is easily misplaced. 
     Therefore, to provide a musician ready access to a drum key, a preferred drum adjustment apparatus 60, in accordance with the present invention, is provided as shown in FIGS. 9-12. The apparatus 60 includes means to rotatably and removably attach the drum key to the user&#39;s clothing. A user of the apparatus can quickly remove the drum key for use and then replace it on his clothing. Alternatively, a user of the apparatus 60 may place himself adjacent a drum and, leaving the apparatus 60 attached to his clothing (e.g. a belt loop), make free drum head tuning adjustments. 
     In particular, FIGS. 9, 10, 11 and 12 are, respectively, front elevation, side elevation, bottom plan and rear elevation views of the apparatus 60. FIG. 9 illustrates the apparatus 60 attached to a user&#39;s belt loop 62. A resilient leather envelope 64 encloses the drum key 40. The envelope 64 defines a hole 66 which receives the drum key end 44 in a manner that exposes the end 44 for use. The envelope 64 also defines a body 68 terminating in a tongue 70 which can be inserted in the yoke 72 of a spring loaded snap 80. The tongue 70 is removably fastened to the body 68 with a conventional snap stud and socket 82. 
     The spring loaded snap 80 defines a loop 84 and a tab 86 is rotatably mounted therein which defines a loop portion 88. When the tab 86 is depressed as shown in FIG. 12 the portion 88 is moved to a position which allows the loop 84 to be attached to the belt loop 62 as shown in FIG. 9. The yoke 72 is rotatably mounted on a stud 90 of the snap 80 thus allowing the envelope 64 and enclosed drum key 40 to rotate while the apparatus remains attached to the belt loop 62. The spring loaded snap 80 is of a type well known in the art. 
     From the foregoing it should now be recognized that a drum adjustment apparatus embodiment has been disclosed herein configured for attachment to a user&#39;s clothes and especially suited for retaining a drum key for ready use in adjusting the tone of a drum head. An apparatus in accordance with the present invention enables a user thereof to reduce time needed to make drum adjustments because the drum key is always readily available for use. 
     The preferred embodiment of the invention described herein is exemplary and numerous modifications, dimensional variations and rearrangements can be readily envisioned to achieve an equivalent result, all of which are intended to be embrace within the scope of the appended claims.
