DETAILED DESCRIPTION
[0044] The detailed description set forth below in connection with the appended drawings is intended as a description of certain embodiments of a dampening device for a snare drum and is not intended to represent the only forms that may be developed or utilized. The description sets forth the various structure and/or functions in connection with the illustrated embodiments, but it is to be understood, however, that the same or equivalent structure and/or functions may be accomplished by different embodiments that are also intended to be encompassed within the scope of the present disclosure. It is further understood that the use of relational terms such as first and second, and the like are used solely to distinguish one entity from another without necessarily requiring or implying any actual such relationship or order between such entities.
[0045] Various aspects of the present disclosure are directed toward an accessory for use with a snare drum to markedly reduce or eliminate unwanted vibrations of drum wires. Such unwanted vibrations are scientifically referred to as “sympathetic vibrations,” but are commonly referred to in the music community as “snare buzz,” and thus, the accessory is adapted to dampen snare buzz.
[0046] Referring now to the drawings,
[0047] According to one embodiment, and referring now to
[0048]
[0049] The upper edge 42 of the base 28 defines a ramp portion 46 extending partially around the circumference of the base 28. The ramp portion 46 includes a lower end located below an upper segment of the upper edge to define a shoulder 48 therebetween. The ramp portion 46 slopes upwardly from the lower end, away from the lower edge 40 to provide a smooth camming surface, the purpose of which will be described in more detail below.
[0050] The base 28 additionally includes a plurality of tracking grooves 50 formed along the inner surface 30 thereof, with each tracking groove 50 having a circumferential component (i.e., extends in a circumferential direction), as well as an axial component (i.e., extends in an axial direction). According to one embodiment, the tracking grooves 50 include a first sloped segment 52, a second sloped segment 54, and a third sloped segment 56, as well as a first rest segment 58, a second rest segment 60, a third rest segment 62, and a fourth rest segment 64. The first rest segment 58 is positioned at an end of the tracking groove 50 adjacent the lower edge 40 of the base 28. The first sloped segment 52 extends upwardly from the first rest segment 58 toward the second rest segment 56. The second sloped segment 54 extends upwardly from the second rest segment 56 toward the third rest segment 62. The third sloped segment 56 extends upwardly from the third rest segment 62 toward the fourth rest segment 64.
[0051] Each tracking groove 50 may be associated with a guide surface and may be sized and structured to receive a respective tracking pin 66, which is connected to a rotating plate 68. The interaction between the tracking grooves 50 and the tracking pins 66 coordinates movement of the rotating plate 68 relative to the base 28, as will be described in more detail below.
[0052] The rotating plate 68 includes a central portion 70 and a raised peripheral portion 72 circumnavigating the central portion 70. The central portion 70 may include a pair of openings 74 to accommodate a pair of magnets 76, as will be described in more detail below. The rotating plate 68 further includes a plurality of lower members 78 extending downwardly from the central portion 70 and/or the raised peripheral portion 72. Each lower member 78 is connected to a respective one of the tracking pins 66. The rotating plate 68 further includes an arm 80 extending radially outward relative to the raised peripheral portion 72.
[0053] A handle 82 may be connected to the arm 80 to facilitate user control over rotation of the rotating plate 68 relative to the base 28. The handle 82 may function as an extension of the arm 80, and may be sized and structured to allow a user to easily manipulate the arm 80 via gripping of the handle 82. The handle 82 may include a pair of openings which may be aligned with a corresponding pair of openings formed on the arm 80 to accommodate a pair of mechanical fasteners, such as a nut and bolt, wherein the mechanical fasteners are advanced through the aligned pairs of openings. The handle 80 may include a logo, or other indicia displayed thereon, with such logo or indicia being laser engraved, stamped, printed or otherwise applied to the handle. A pair of finger grips 84 may be coupled to opposed sides of the handle 80 adjacent a distal end thereof. The finger grips 84 may be formed from silicone, rubber, or other materials known in the art.
[0054] The rotating plate 68 is operatively coupled to an upper assembly 86, which generally includes a mounting plate 88, an adhesive 90, and the dampening pad 24. The mounting plate 88 includes a central portion 92 and a raised peripheral portion 94. The dampening pad 24 may have an outer circumference that is substantially identical to the outer circumference of the raised peripheral portion 94 to create a substantially flush appearance. The dampening pad 24 may also include a pair of opposed faces 96, 98 to define a dampening pad thickness therebetween. Exemplary thicknesses include 4mm and 8 mm, although other thicknesses may be defined by the dampening pad 24 without departing from the spirit and scope of the present disclosure. The dampening pad 24 may be secured to the mounting plate 88 via the adhesive 90, which may include tape or other adhesives known in the art.
[0055] The central portion 92 of the mounting plate 88 includes a pair of openings 100 sized to receive a pair of magnets 102, wherein the magnets 102 received in the mounting plate 88 are magnetically attracted to the magnets 76 received in the rotating plate 68 to effectuate magnetic coupling therebetween. Such magnetic coupling also allows for selectively swapping of one upper assembly 86 with another upper assembly 86 to achieve a desired damping effect through variance of the dampening pad thickness. Along these lines, by swapping upper assemblies 86, a user may easily modify the dampening pad thickness to the desired thickness.
[0056] With the basic structure of the dampening device 22 being described above, the following is a description of an exemplary use of the dampening device 22. The dampening device 22 is attached to a drum stand 12 by placing the base 28 over the support arms 38 of the drum stand 12, with the support arms 38 being received in respective ones of the recesses 34 formed in the base 28. The rubber liner 44 may frictionally engage with the support arms 38 of the drum stand 12 to stabilize the base 28 relative to the drum stand 12.
[0057] The dampening device 22 may be configured for use with a particular drum 10 by adjusting the size of the dampening pad 24. Along these lines, dampening pad thickness may be varied to accommodate a particular type of drum 10, size of drum 10, or desired dampening effect. For instance, for drums 10 that are configured to rest further away from the dampening device 22, a thicker dampening pad 24 may be required, and vice versa. Furthermore, a thicker dampening pad 24 may be used to create a greater dampening force on the drum 10, while a thinner dampening pad 24 may be used to create a lesser dampening force on the drum 10. As such, modification of the dampening pad thickness may be achieved by removing one upper assembly 86 from the rotating plate 68 and placing a desired upper assembly 86 on the rotating plate 68. To remove an upper assembly 86 from the rotating plate 68, a user simply pulls the upper assembly 86 away from the rotating plate 68 with sufficient force to overcome the magnetic attraction between the magnets 102 in the upper assembly 86 and the magnets 76 in the rotating plate 68. The user then places the desired upper assembly 86 on the rotating plate 68, with the magnets 102 in the upper assembly 86 being aligned with the magnets 76 in the rotating plate 68 so as to allow for magnetic attraction therebetween to hold the upper assembly 86 in place relative to the rotating plate 68 during use of the dampening device 22.
[0058] With the drum 10 residing on the drum stand 12 above the dampening device 22, and when the user desires to impart a dampening force on the drum 100, the handle 82 is gripped by the user and is moved so as to rotate the handle 82 about the central axis 26, which causes the rotation plate 68 to rotate relative to the base and transition from a lowered position toward a raised position relative to the base 28.
[0059] More specifically, as the rotation plate 68 rotates relative to the base 28, the tracking pins 66 travel within their respective tracking grooves 50 from the lower end of the respective tracking groove 50 toward the upper end of the respective tracking groove 50, and the arm 80 rides along the ramp portion 46 of the upper edge 42. Each tracking pin 66 starts at the first rest segment 58, and then sequentially travels along the first sloped segment 52 to the second rest segment 56, then along the second sloped segment 54 to the third rest segment 62, and then along the third sloped segment 56 to the fourth rest segment 64. As the tracking pins 66 move along their tracking grooves 50 from the first rest segment 58 toward the fourth rest segment 64, the rotation plate 68 not only rotates about the central axis 26, the rotation plate 68 also moves axially along the central axis 26 to move away from the base 28 (e.g., lifting of the central portion 70 of the rotation plate 68 above the base 28). In this regard, the interaction between the tracking pins 66 and the corresponding tracking grooves 68 transfers such rotational movement of the rotation plate 68 relative to the base 28 into axial movement of the rotation plate 68 relative to the base 28. Rotation of the rotation plate 68 in a first rotational direction results in movement of the rotation plate 68 away from the base 28, as described above, while rotation of the rotation plate 68 in an opposing second rotational direction results in movement of the rotation plate 68 toward the base 28 (e.g., lowering of the central portion 70 of the rotation plate 68 toward the base 28). In this respect, the rotation plate 68 is rotatable relative to the base 28 between a first rotational position and a second rotational position, wherein the first rotational position is associated with a lowered axial position, and the second rotational position is associated with a raised axial position. According to one embodiment, the rotation plate may rotate 120 degrees or less to complete transition between the lowered axial position and the raised axial position. The second and third rest segments 56, 62 may provide intermediate stopping points for the tracking pins 66 to allow the rotation plate 68 to remain at an axial position between a lowered axial position and a raised axial position.
[0060] As the rotation plate 68 is lifted from the base 28, the dampening pad 24 may engage the drum wires 14 on the drum 10 to mitigate any unwanted vibrations thereof. To release the dampening pad 24 from the drum wires 14, the handle 82 is rotated in the opposite direction, which results in opposite relative rotational movement of the rotation plate 68 relative to the base 28. As such, assuming the tracking pins 66 are in the fourth rest segment 64, the tracking pins 66 sequentially travel from the fourth rest segment 64 along the third sloped segment 56 to the third rest segment 62, then along the second sloped segment 54 to the second rest segment 56, and then along the first sloped segment 52 to the first rest segment 58 to assume the lowered axial position.
[0061] According to one embodiment, the dampening pad 24 may be formed from ¼″ thick ultra-soft, open cell, super absorbent polyurethane foam, which has the ability to reduce snare buzz when pressed against the wires 14 while applying very little pressure to the wires 14. Along these lines, it is desirable to stop the snare wires 14 from vibrating in response to ambient sounds while applying a minimal amount of pressure to the wires 14. As more pressure is applied to the wires 14, the configuration of the wires 14 may be altered which may reduce the ability of the wires 14 to vibrate, and thus, alter the natural sound of the drum 10. Therefore, by applying minimal pressure to the wire 14, the snare buzz can be mitigated, while also preserving the integrity of the wires 14. Although polyurethane foam is the preferred material, it is also contemplated that wood, fabric, rubber, other foams, felt, metal and plastic may be used to fabricate the dampening pad 24 without departing from the spirit and scope of the present disclosure.
[0062] Referring now to
[0063] The base 112 is disposed about central axis 115 and defines a generally circular, ring-like configuration. The base 112 includes a plurality of tracking grooves 118 that extend completely between an inner surface 120 and an outer surface 122 of the base 112. The shape of the tracking grooves 118 may be similar to those described above, and include a plurality of sloped segments and a plurality of rest segments. The base 112 includes an upper edge 124 and a lower edge 126, wherein the distance between the upper and lower edges 124, 126 is substantially uniform around the circumference of the base 112. In other words, the base 112 may be formed without an inclined ramp section on the upper edge 124.
[0064] An intermediate plate 128 may be positioned between the rotating plate 114 and the base 112, and may provide an underlying surface which may assist in capturing magnets 130 in openings 132 formed in rotating plate 114. The intermediate plate 128 may be connected to rotating plate 114 via screws 134 or other fasteners.
[0065] The rotating plate 114 may also be connected to tabs 136, which extend in an axial direction from the rotating plate 114, and are connected to pins 138, which extend in the tracking grooves 118. Thus, as the pins 138 travel through their respective tracking grooves 118 as a result of rotating of the rotating plate 114 relative to the base 112, the axial position of the rotating plate 114 relative to base 112 may vary.
[0066] The rotating plate 114 may be integrally connected with a handle 140, which may extend radially outward therefrom. The handle 140 may be connected with a finger tab 142 having opposed finger grips 144 to aid in gripping the handle 140.
[0067] The dampening pad 116 may be coupled to the rotating plate 114, at least in part, through the use of an adhesive layer 146 positioned between the dampening pad 116 and the rotating plate 146. Magnets may also be used to couple the dampening pad 116 to the rotating plate 114, particularly to facilitate swapping of one dampening pad 116 for another having a different thickness.
[0068] Although the dampening devices 22, 110 discussed above are suitable for mitigating unwanted vibrations of the snare drum wires 14, their contact with the wires 14 may make it difficult to play the snare drum 10 and achieve a desired sound when the dampening pads 24, 116 are engaged with the drum wires 14. Accordingly,
[0069] According to one embodiment, the engagement disc assembly 300 includes a lower plate 304 having an upper surface 306 and an opposing lower surface 308. The lower plate 304 may be circular and adapted to be selectively engageable with the rotating plate 68, 114 of the dampening device 22, 110. Thus, the outer diameter of the lower plate 304 may be similar to that of the rotating plate 68, 114. The lower plate 304 may be fabricated from plastic, rubber, wood, metal, or other materials known in the art.
[0070] The lower plate 304 may be engaged with a foam layer 310, which may be sized to extend over the upper surface 306 of the lower plate 304. The foam layer 310 may include a quadrangular opening 312 formed therein and sized to receive the elongate, rigid bar 302.
[0071] The elongate, rigid bar 302 may include an engagement wall 314 and an attachment flange 316, with the engagement wall 314 extending from the attachment flange 316 and terminating at a distal edge 318. The distal edge 318 may extend along a longitudinal axis 320, that may be generally parallel to a diameter of the lower plate 304 and the foam layer 310. The attachment flange 316 may extend from opposite sides of the engagement wall 314 and substantially along the entire length of the engagement wall 314. The outer periphery of the attachment flange 316 may be complementary in shape to the periphery of the opening 312 formed in the foam layer 310, which may allow the attachment flange 316 to be secured directly to the lower plate 304, with the foam layer 310 extending outwardly from the attachment flange 316. The attachment flange 316 may include a plurality of openings formed therein to facilitate securing of the attachment flange 316 to the lower plate 304. In the exemplary embodiment, the attachment flange 316 includes an opening adjacent each corner thereof which is sized to receive a shaft of a screw 322, which mates with an internally threaded opening formed in the lower plate 304. It is also contemplated that rivets, nails, adhesives or other mechanical fasteners may be used without departing from the spirit and scope of the present disclosure. The elongate, rigid bar 302 may be formed from stainless steel or other materials known in the art.
[0072] The distal edge 318 may be spaced from an upper surface of the attachment flange 316 to define a distal edge height. Different elongate, rigid bars 302 may be associated with different distal edge heights. Drums may come in different sizes, and thus, the size of the distal edge height may be selected based on the size of the drum with which the engagement disc assembly 300 will be used. For instance, an elongate, rigid bar 302 having a larger distal edge height may be preferred for a larger drum, while an elongate, rigid bar 302 having a smaller distal edge height may be preferred for a smaller drum.
[0073] The engagement disc assembly 300 may be selectively swapped or switched out with the upper assembly 86 or dampening pad 116 of the dampening devices 22, 110 described above. In this regard, the engagement disc assembly 300 may include magnets similar to the magnets associated with the upper assembly 86 or dampening pad 116 to facilitate incorporation of the engagement disc assembly 300 into the dampening device 22, 110. However, the scope of the present disclosure is not limited thereto, and thus, other detachable engagement means may also be used, such as snap fit engagement, detents, etc., to allow for detachable engagement between the engagement disc assembly 300 and the corresponding components of the dampening device 22, 110.
[0074] In use, the engagement disc assembly 300 may be attached to the rotating plate 68 of the dampening device 22 or the rotating plate 114 of the dampening device 110. When attached, the engagement disc assembly 300 may move in concert with the rotating plate 68, 114 between the first rotational position and the second rotational position to adjust the position of the distal edge 318 of the engagement wall 314 relative to the drum wires 14. When the rotating plate 68, 114 is in the first rotational position, the distal edge 318 is positioned away from the drum wires 14 to allow for unrestricted vibration of the drum wires 14. However, by transitioning the rotating plate 68, 114 from the first rotational position to the second rotational position, the distal edge 318 is moved into contact with the drum wires 14 to restrict some vibration of the drum wires 14, while also allowing for some vibration of the drum wires 14.
[0075] The configuration of the engagement wall 314, and in particular, the limited surface area of the distal edge 318, may significantly reduce the contact area of the dampening device 22, 110, when compared to the dampening pads 24, 116. The reduced contact area may reduce the choking or dampening effect of damping device 22, 110 has on the snare drum sound when playing the snare drum 10 while the distal edge 318 is engaged with the drum wires 14.
[0076] The particulars shown herein are by way of example only for purposes of illustrative discussion, and are not presented in the cause of providing what is believed to be most useful and readily understood description of the principles and conceptual aspects of the various embodiments of the present disclosure. In this regard, no attempt is made to show any more detail than is necessary for a fundamental understanding of the different features of the various embodiments, the description taken with the drawings making apparent to those skilled in the art how these may be implemented in practice.
