  The present invention relates to the structure and design of musical instruments, and more specifically to the drum structure and design.

  The artistic expression can be conveyed in any one of several media including music. Musical instruments provide tools that are used to express musicality. A drum or percussion instrument is generally one such tool.

  The drum structure and design remains unchanged for several generations. This unchanged structure and design has maintained the sound quality that was produced by the early implementation of the instrument. Although currently standard and common, the sound produced by a drum constructed according to conventional structure and design is attenuated and muted. This is because of the structural features built into the shell that interfere with the drum shell's ability to resonate and produce a complete and rich sound.

  FIG. 1 shows a drum structure and design that is common in the prior art. The drum is comprised of a pair of drum hoops or rims, a shell, a set of lugs, and a corresponding set of lug holders mounted across the sides of the drum shell.

  Each hoop houses a drum head. The drum head is a contact surface that vibrates when struck during performance. For a typical drum, the drum head on the top side of the drum, sometimes referred to as a grasshopper head, is the portion of the drum that the drummer strikes when playing the instrument. The drum head on the bottom side of the drum provides resonance and is usually thinner than the drum head on the top side.

  Multiple tuning assemblies on the drum hoop can be used to adjust the tension on the drum head, thereby tuning the sound of the drum head and allowing different drum heads to be coupled to the shell mount . The drum hoop also includes various holes. A set of lugs can pass through the holes and connect to a corresponding set of lug holders mounted across the sides of the drum shell.

  The shell is the drum body. It is based in part on the resonance of the materials that make up the drum shell and produces most of the acoustic properties of the drum. When an impact is applied to the drum head, the drum head vibrates. When a drum hoop is tightly connected to a drum shell using a lug tightening system, vibration is transmitted from the drum head to the hoop containing the drum head and distributed across the shell. These vibrations then resonate the drum shell, which in turn creates some of the acoustic properties of the drum. Often drum shells contain small holes called vent holes. The vent hole releases air when the drum is struck, which in turn improves the drum resonance.

  However, the conventional drum structure and design shown by FIG. 1 prevents this resonance. This is due to the attachment of multiple lug holders 110 across the drum shell. Specifically, when a plurality of lugs are placed and tightened in a plurality of lug holders to connect the drum hoop to the shell, a force is applied to the plurality of lug holders based on how tight the lugs are tightened. The force is then transferred to the drum shell along a plurality of points where the lug holders are connected to the shell. This force pulls the drum shell in at least one direction and prevents the drum shell from fully resonating in the opposite direction (s). This weakens and mutes the overall sound generated by the drum.

  Traditional drum structures and designs further illustrate the manufacture and production of current drum shells, with some examples being metal (eg steel or brass), wood (eg birch, maple, oak, etc.) and acrylic Limiting the sound that can be generated by the drum by limiting to high density materials such as, thicker structures, or some combination of both. The drum shell is distorted or broken when absorbing or countering multiple forces applied by multiple lug tensions from the drum hoop to multiple lug holders mounted along the side of the drum shell. In order to prevent, the density of the material of the drum shell and the thickness of the drum shell are required. As a result, a large force is generated on the drum shell. This is why some shells are manufactured up to 20 millimeters thick. In these examples, more energy is required to cause resonance from such multiple shells. Also, due to the density and thickness, the drum shell will vibrate at a higher natural frequency. Thus, the sound profile produced by the drum is defined by and limited to the multiple resonance characteristics provided by these denser or thicker materials. Unless a drum shell with a reduced thickness is used in a drum shell configuration, or a material with a lower density is used and the drum shell is not allowed to resonate freely, the potential range of drum shell sound is reduced. It cannot be realized completely. Both of these attributes will result in less acoustic energy from the struck drum head required to create resonance from the drum shell. This will therefore give the drum a more efficient resonant sound profile.

  In an attempt to remedy some of these disadvantages, alternative drum designs have been proposed. One such alternative design is provided in US Pat. No. 5,410,938. The provided design is based on the use of multiple tension rods extending from the top drum hoop (ie, batter side) to the bottom drum hoop, and multiple rod holders instead of drum shells. By connecting to the drum shell, the drum shell resonance is released. This design improves the potential resonance characteristics of the drum shell, but at the expense of achieving other sacrifices in drum sound quality. Specifically, this design produces a distorted, impure sound, as vibrations from the drum head are distributed not only across the drum shell but also to each of the tension rods. As a result, multiple tension rods absorb vibration each time the drum head is struck, causing the tension rods to generate additional undesirable sound (ie, rattling) along with the expected drum sound. These undesirable sounds are the result of a failure to isolate the mount or tuning mechanism (ie, tension rod and rod holder) from the drum's multiple sound producing elements (ie, drum head and shell). is there.

  Therefore, a new that provides a pure and unimpeded sound by allowing the drum shell to resonate freely without distortion or attenuation due to a mount or tuning mechanism mounted across the side of the drum shell There is a need for drum construction and design. In other words, there is a need for a new drum structure and design in which the support frame connects the sound generation elements of the drum together in a manner that protects the acoustic energy emanating from the sound generation elements from the support frame. By addressing these needs, you can create a drum with unparalleled sound. The drum design may further improve the sound profile of the drum by addressing the need to reduce multiple forces applied to the drum shell. In doing so, such a design allows a plurality of shells composed of thinner materials to be incorporated into the drum structure, which is similar to a thicker or higher density similar shell. It will provide resonances that are larger than those, and different acoustic properties.

  Provides a drum structural frame that distributes the same energy to the freely resonating drum shell while reducing or preventing the energy from the drum head from spreading across the entire structural frame It is one purpose. Accordingly, it is an object to provide a drum structure frame that achieves a pure drum sound profile in which drum shell resonance is not disturbed and distortion and other undesirable sounds are eliminated by the structure frame. .

  These and other objects are achieved by the Altimount structural frame of some embodiments. The Ultimount structural frame includes a top shell mount, a bottom shell mount, a plurality of rod holders, and a plurality of tension rods. Inherent in multiple Ultimount rod holders is its built-in damping solution. The attenuation solution reduces the spread of energy applied to multiple sound generating elements during performance to multiple non-sound generating elements of the structural frame, or completely isolates them from spreading. Contain that same energy.

  The top shell mount includes a die cast hoop, a bearing edge ring, and a tension ring. The top shell mount fixes and tunes the first drum head of the drum to the drum shell without blocking the drum shell resonance. The bottom shell mount includes a complementary die cast hoop, a bearing edge ring, and a tension ring that secures and tunes the second drum head without interrupting the resonance of the shell. Specifically, the first set of rod holders is coupled to the top shell mount, and the combined second set of rod holders is coupled to the bottom shell mount. The plurality of tension rods connect the first set of rod holders to the corresponding second set of rod holders. Multiple tuning assemblies on multiple rod holders can be used to adjust the distance separating the top shell mount from the bottom shell mount, thereby controlling the compression force applied to the drum shell. Because the drum shell itself is only contacted by the lower surface of the top shell mount and bottom shell mount along its top and bottom distal edges, the compression force does not obstruct the drum shell resonance, so that the drum shell is in place. Hold on. Compared to other designs where multiple external forces applied to the drum shell attenuate the sound by blocking the drum shell resonance, the drum shell free resonance produces a richer and more complete sound profile To do. These external forces typically become apparent when multiple lug holders or other multiple forces are placed or applied along the sides of the drum shell. The added undesirable side effect of these external forces is the need for thicker drum shells. The greater the thickness of the drum shell, the greater the amount of energy required to produce resonance and produce sound. However, the design claimed herein removes such external forces from the drum shell, so thinner drum shells that were previously inappropriate, or less dense plastic, Multiple drum shells using materials such as clay and glass can now be used. As a result, the door to a new evolution of drum sounds is opened.

  Further, each rod holder is connected to either the top shell mount or the bottom shell mount by one or more isolation rings that serve as a plurality of vibration damping members. Multiple damping members isolate the energy passing from the drum head to the drum shell so that it does not spread across the entire structure of the tension rod and rod holder that holds the drum head and drum shell together To do. This prevents multiple tension rods and other structural frame elements from vibrating or generating other undesirable sounds, or otherwise reverberation that would ruin the drum's sound profile. Can be removed.

  In order that the nature of the present invention may be better understood, a preferred embodiment of an artimount structural frame will be described by way of example only with reference to the accompanying drawings.

  FIG. 2 illustrates the Ultimount drum design and structure of some embodiments. Unlike prior art multiple drum designs and structures, the AltiMount is in a way that does not block drum shell resonance and in a way that isolates the sound generating drum head and the non-sounding support frame from the shell. Connect the drum head to the drum shell. In doing so, Ultimount offers several advantages over prior art multiple drum designs and structures. First, because Altimount does not block drum shell resonances during performance, Altimount provides a richer and more fully audible drum. Second, due to the isolation of the structural frame from the drum's multiple sound generating elements, Altimount removes unwanted and distorted sounds from the drum's overall sound profile. Third, since Altimount removes multiple external forces applied to the drum shell by other frames, Altimount allows for the overall production of new drum shells, The drum shell can be made of a thinner structure and / or less dense material, thus providing better resonance.

  As shown in FIG. 2, the Ultimount structural frame includes a top shell mount 210, a plurality of rod holders 220, a plurality of tension rods 230, and a bottom shell mount 240. This structural frame connects the drum head to the shell. More importantly, this structural frame causes the acoustic energy applied to the drum head during performance to not spread over the entire structural frame and to cause distorted or undesirable sound. It is to ensure that it is distributed to drum shells that are not obstructed and resonate freely.

  The top shell mount 210 and the bottom shell mount 240 are made of a rigid material such as metal (for example, brass, steel, etc.) or carbon fiber. Each shell mount 210 and 240 includes a die cast hoop, a bearing edge ring, and a tension ring. FIG. 3 provides a partially exploded view of the Altimount structural frame showing the die cast hoop 310, the bearing edge ring 320, and the tension ring 330 of the top shell mount 210. FIG. 4 provides an alternative exploded view showing the die cast hoop 310, the bearing edge ring 320, and the tension ring 330 of the top shell mount 210. For simplicity, the die cast hoop is interchangeably referred to as the upper ring, and the tension ring is interchangeably referred to as the lower ring.

  A lower ring or tension ring 330 is attached to the top of the outer edge of the drum shell. The tension ring 330 has a hollow internal cavity with a recessed groove 340 extending centrally along the circumference of the ring.

  The bearing edge ring 320 has a downwardly protruding edge that allows the bearing edge ring 320 to fit within the recessed groove of the tension ring 330 and assist in precise tuning of the drum. Thereby, the bearing edge ring 320 can be easily replaced, so that the Ultimount frame can accommodate a plurality of bearing edges cut at various angles. Each angle changes the tonality of the drum, and more generally changes the sound profile. Some embodiments provide a bearing edge cut at 30 degrees, and other embodiments provide a bearing edge cut at 45 degrees. When the drum head is placed on the top of the 30 degree bearing edge, tuned and played, the resulting sound has a mellow attack and short sustain, while the drum head is on the top of the 45 degree bearing edge. When placed, tuned and played, the resulting sound has a large attack and a long sustain. These angles are provided for illustrative purposes. Thus, the ring 320 is not limited to these angles and can be cut at any other angle. FIG. 5 provides a cross-sectional view of a plurality of different bearing edge rings 510, 520, 530, and 540, each cut at a different angle, that can be inserted into a tension ring, according to some embodiments.

  The interchangeability of the bearing edge ring 320 within the tension ring 330 provides the user with a quick, simple and cost-effective means for changing the drum sound profile. The interchangeability also allows the first bearing edge ring cut at the first angle to be inserted into the tension ring of the top shell mount, and the second bearing edge cut at the second different angle. Allows the ring to be inserted into the tension ring of the bottom shell mount. The bearing edge ring 320 may be made from steel, brass, wood, or carbon fiber as some examples.

  As mentioned above, the drum head is located on top of the bearing edge ring 320 and the upper ring or die cast hoop 310 is located on the drum head and secured to the tension ring 330. Typically, the die cast hoop 310 is made relatively large with respect to the tension ring 330 so as to fit around the outer periphery of the tension ring 330. Drum head tension is achieved by tightening or loosening a set of screws or lugs that pass through a plurality of holes along the die cast hoop 310 and are screwed into a corresponding set of screw holes along the outer edge of the tension ring 330. Adjusted. Examples of these screw holes are shown in FIG. By fixing the tighter die cast hoop 310 to the tension ring 330, the force applied to the drum head becomes larger. By adjusting this force, the tightness of the drum head is controlled, and the drum head sound is tuned accordingly. In some embodiments, a torque wrench may be used to tighten multiple screws or lugs, thereby achieving the desired level of tension in the drum head. A plurality of different drum heads can be inserted between the top shell mount 210 and the bottom shell mount 240. Thereby, the drum can be played, for example, as a “tom” at one end or drumhead on the top or batter side of the drum and as a “snare” at the other end.

  In some embodiments, the tension ring 330 includes one or more guides that assist in coupling the shell mount to the drum shell. FIG. 6 shows a tension ring having at least one guide 610. The guide 610 is a protrusion extending from the lower surface inside the tension ring. A plurality of guides are used to fit the tension ring directly above the drum shell by positioning it along the periphery of the drum shell.

  The tension ring 330 or lower ring of each shell mount 210 and 240 serves two purposes. As mentioned above, the first objective relates to holding the drum head and performing tuning in connection with the die cast hoop 310. A second object relates to coupling the drum head to the drum shell to disperse the same energy from the drum head to the drum shell while preventing acoustic energy from spreading across the entire structural frame. The isolation of acoustic energy is realized based on the design and structure in which vibration is isolated from the rod holder 220 and the plurality of tension rods 230 connected to the tension ring 330 of each shell mount 210 and 240.

  In some embodiments, when the tension ring 330 is positioned over the end edge of the drum shell, the tension ring 330 extends several millimeters away from its center beyond the face of the end edge of the shell. As such, the tension ring 330 has a width and height of 5-30 millimeters. In some other embodiments, the tension ring 330 is based on a cover that protrudes from the tension ring 330 with a radius that is greater than the radius of the drum shell edge, and vertically below the end edge face of the shell. Extends toward the center. In any configuration, a plurality of openings are opened across the circumferential surface of the tension ring.

  Referring again to FIG. 2, the first set of rod holders 220 are coupled to the tension ring of the top shell mount 210 at the provided openings. Similarly, the second set of rod holders 220 are connected to the tension ring of the bottom shell mount 240 at a plurality of provided openings. The multiple rod holders 220 are unique compared to those of the prior art due to their vibration isolation design and structure. The plurality of holders 220 reduces the energy applied to the drum head during performance, or is more completely isolated from the structural frame that holds the drum together, more specifically from the tension rod 230. This prevents the tension rod 230 from causing rattling during the performance or generating other undesirable sounds.

  In the embodiment shown in FIG. 2, the plurality of rod holders 220 face outward so that the plurality of tension rods 230 extend longitudinally along the exterior of the drum shell. However, other embodiments, such as those depicted in FIG. 7, have a structural frame in which a plurality of rod holders 220 are facing inward such that a plurality of tension rods 230 extend longitudinally within the drum shell. Prepare the body.

  An exploded view of the rod holder 220 according to some embodiments is provided in FIG. The figure shows a plurality of structural elements that isolate acoustic energy from spreading through the Altimount structural frame. As shown, the rod holder 220 is composed of a binding anchor 810 formed with three faces, a vibration damping assembly 815, and a tension assembly 820.

  A three-faced binding anchor 810 is used in conjunction with the vibration damping assembly 815 to secure the rod holder 220 to one of the plurality of shell mounts and to isolate the structural frame from the drum head and drum shell. Including horizontal threaded openings. The binding anchor 810 formed with three surfaces also includes vertical openings on both sides. One end of the vertical opening on both sides receives the tension rod 230. The tension rod 230 passes to the other end where it is secured using the threaded nut 870 of the tension assembly 820.

  The vibration damping assembly 815 includes a bolt 830, a plurality of spacers 840, a plurality of damping members 850, and a plurality of gripped end caps 855. In some embodiments, the plurality of end caps 855 and the plurality of spacers 840 are made from metal for structural integrity or from carbon fiber for high tensile strength. The plurality of damping members 850 are made from a plurality of absorbent and attenuating materials. In some embodiments, the plurality of damping members 850 are a plurality of isolation rings made from rubber, although other materials such as carbon fibers can also be used. Also, in some other embodiments, the plurality of end caps 855 and the plurality of spacers 840 are made from a plurality of absorbent and attenuating materials to compensate for the attenuation provided by the plurality of isolation ring damping members 850. It is done.

  The vibration damping assembly 815 secures the rod holder 220 to one of the shell mounts 210 and 240, and more importantly, the shock mount energy applied to the drum head brings the drum together. Prevents you from passing through. In doing so, the gripped end cap 855 is positioned on both sides of the opening along one circumferential surface of the plurality of tension rings. Each gripped end cap 855 includes a set of conical protrusions that minimize surface contact with the circumferential surface of the tension ring. By minimizing the contact surface between the plurality of gripped end caps 855 and the peripheral surface, the amount of energy transferred to the structural frame must be minimized and thereby attenuated within the structural frame. The amount of energy is minimized. Also, by minimizing the amount of energy transmitted to the structural frame, more of the energy is stored and transmitted to the drum shell, resulting in a more complete and less muted sound. In some embodiments, the circumferential surface of the tension ring includes a set of recessed guides for the set of conical protrusions of the plurality of end caps 855. A damping member 850 in the form of an isolation ring or bush is positioned along the opposite side of any gripped end cap 855. Finally, spacers 840 are positioned on both sides of the plurality of damping members 850. In some embodiments, each of the plurality of end caps 855, the plurality of damping members 850, and the plurality of spacers 840 are positioned along the interior of the tension ring or along the exterior. The shape can be convex or concave.

  Each of the plurality of end caps 855, the plurality of damping members 850, and the plurality of spacers 840 has a circular hole sized to receive a bolt 830 at the center thereof. Once the elements are positioned, bolts 830 are passed through each of the elements, with the tension ring opening in the center of the arrangement. The bolt 830 is screwed into the horizontal threaded opening of the binding anchor 810 formed with three faces. As a result, the rod holder 220 is fixed to the tension ring of either the top shell mount 210 or the bottom shell mount 240. In addition, it establishes the necessary contact that allows the damping member 850 to absorb energy and prevent it from being transferred to the structural frame.

  Also, the plurality of end caps 855, the plurality of damping members 850, and the plurality of spacers 840 are sized according to the radial height of the tension ring to which they are attached. In some embodiments, the radial height varies based on the size (or diameter) of the drum shell and the corresponding size of the shell mount that fits into the drum shell. The differently sized end caps 855, the plurality of damping members 850, and the plurality of spacers 840 provide a plurality of components by providing sufficient contact between the tension ring and the vibration damping assembly 815. Avoid being too large to extend beyond the radial height of the tension ring, or too small to allow them to pass through rather than engaging openings along the circumference of the tension ring While ensuring proper attenuation. This also ensures that the plurality of conical projections of the plurality of end caps 855 fit into the plurality of recessed guides along the circumferential surface of the tension ring when a plurality of guides are present. To do.

  FIG. 9 provides another exploded view of the bolt 830, the plurality of spacers 840, the plurality of damping members 850, and the plurality of gripped end caps 855 that comprise the vibration damping assembly 815 of the plurality of rod holders 220. FIG. 10 shows the completed vibration damping assembly secured to one of the shell mounts 210 or 240. FIG. 11 provides an alternative representation for a completed vibration damping assembly secured to one of the shell mounts 210 or 240, according to some embodiments.

  In some embodiments, the tension ring opening is slightly larger than the bolt 830. By providing additional spacing at the tension ring opening, air is released when the drum is struck, thereby providing ventilation and improved resonance. In some embodiments, the peripheral surface of FIG. 12 provides two views showing an enlarged tension ring opening, according to some embodiments.

  Referring back to FIG. 8, the tension assembly 820 is comprised of a top bolt 860, a washer 865, and a threaded nut 870. FIG. 13 illustrates an exploded view of a tension assembly 820 of some embodiments. FIG. 14 provides an alternative exploded view, shown offset from one another, for some embodiments of the tension assembly 820. The tension assembly 820 operates in conjunction with the three-faced binding anchor 810 and the tension rod 230 to secure the drum shell between the top shell mount 210 and the bottom shell mount 240 of the Alti mount.

  In some embodiments, each tension rod 230 is a hollow shaft that includes an outer thread and an inner thread at each end of the rod. In some embodiments, the plurality of tension rods 230 are made from metal, carbon fiber, or other rigid materials. Reference marker 1410 in FIG. 14 indicates the outer thread, and reference marker 1420 points to the position of the inner thread. This configuration results in a two-stage male-female coupling mechanism in which the tension rod 230 is attached and secured to the anchor 810.

  To complete the first stage of the male-female coupling mechanism, the outer threaded end of the tension rod 230 is threaded through the first threaded nut 880, through the vertical opening of the anchor 810, Then, the other end of the anchor 810 is fixed to the second threaded nut 870. Completing the first stage provides a loose connection of the tension rod 230 to the anchor 810, thereby securing the tension rod 230 to a shell mount to which a rod holder for the anchor is connected. The other outer threaded end of the tension rod 230 is similarly secured to a rod holder connected to the opposing shell mount using a complementary second threaded nut 870. When multiple nuts 870 are tightened, the distance separating the shell mounts 210 and 240 is shortened, which compresses the drum shell even placed between the mounts 210 and 240. In some embodiments, the end of the tension rod 230 is at least 4 cm away from the top of the anchor so that the distance between the two connected shell mounts 210 and 240 can differ by a total of 8 cm. The tension rod 230 can be screwed through a nut 870. The distance separating shell mounts 210 and 240, and the desired compressive force applied to the drum shell disposed therebetween, can be specifically dialed using a torque wrench tightening nut 870. This customizability optimizes the Altimount frame for multiple drum shells of different multiple materials. For example, an Ultimount frame can be used with a plurality of more brittle drum shells, such as those made from glass, by reducing the compressive force on the shell, but the Ultimount frame is made of wood With a more rigid drum shell, etc., it can be used by increasing the compressive force for that type of shell material.

  Once the desired distance between the mounts 210 and 240 is achieved and the desired compression force is applied to the drum shell using the second threaded nut 870 and tension rod 230, the top of the tension assembly 820 Bolts 860 are used to lock the position of the second threaded nut 870 relative to the tension rod 230. The outer thread of the top bolt 860 is screwed to the inner thread of the tension rod 230, thereby completing the second stage of the male-female coupling mechanism. Specifically, the top bolt 860 passes through the washer 865 and is screwed to the tension rod 230 until the end cap of the top bolt 860 presses the lower surface of the washer 865 against the top of the second threaded nut 870. . In doing so, the top bolt 860 prevents vibrations from changing the position of the second threaded nut 870 on the tension rod 230, thereby separating the shell mounts 210 and 240, and the result. As described above, the compression force applied to the drum shell is maintained by the connection of the plurality of shell mounts using the tension rod 230 and the tension assembly 820. Washer 865 can be varied in thickness to allow top bolt 860 to be tightened when there is a spatial separation between second threaded nut 870 and top bolt 865.

  In some embodiments, the Altimount structure and design is adapted to incorporate a plurality of different elements in addition to or in place of those described above. For example, in some embodiments, the plurality of tension rods may comprise a plurality of shafts that include only a plurality of outer threads, thereby eliminating the need for a top bolt 860.

  As is clear from the drawings, according to the Alti mount design, the drum shell is only subjected to compressive force based on contact between the drum shell and the top shell mount 210 and bottom shell mount 240. . In other words, the drum shell receives a force in the y-axis direction. However, no force in the x-axis direction is applied to the drum shell. Any such x-axis force is applied to the top shell mount 210 and the bottom shell mount 240 based on the coupling of the rod holder 230 to a plurality of shell mounts. By removing the x-axis force applied to the shell, the Altimount structural frame can be attached to multiple shells made of a material that is thinner than the thickness typically required for conventional drum mounts. Specifically, the Ultimount structural frame also accommodates multiple drum shells made primarily from plastic, clay, or glass. These materials have resonance characteristics that are different from conventional wood, steel, or brass shells. As a result, Altimount opens the door to a new evolution in drum sound.

  Some embodiments provide an improved rod holder assembly that further isolates the transfer of energy from the drum head to the structural frame. On the one hand, the assembly of FIG. 8 provides energy absorption and vibration damping along the horizontal plane where the assembly connects to the drum shell mount, while the improved rod holder assembly secures the tension rod to the assembly anchor. It also incorporates energy absorption and vibration damping elements along the vertical plane used for This further ensures that the energy transferred from the drum head to the Altimount structural frame does not transfer to the tension rod and cause any rattling or other distortion to the drum sound.

  FIG. 15 illustrates an exploded view of the components of the improved rod holder assembly 1500, according to some embodiments. FIG. 16 illustrates assembly of an improved rod holder assembly 1500, according to some embodiments. The improved rod holder assembly 1500 depicted in FIGS. 15 and 16 includes an anchor 1510, a pair of end caps 1520, a pair of vibration absorbing bushings 1530, a first pair of washers 1540, a tension bolt 1550, and a first outer nut. 1560, a second pair of washers 1570, a lockdown bolt 1580, a second outer nut 1585, and a tension rod 1590. These parts are displayed according to the order in which they are assembled. The part displayed closest to the anchor 1510 is positioned and fixed first, and the part farthest from the anchor 1510 is positioned and fixed last.

  The anchor 1510 remains almost unchanged from the binding anchor 810 formed with the three faces of FIG. Anchor 1510 includes a horizontal threaded opening that is secured to one of a plurality of drum shell mounts using the same or similar vibration damping assembly 815 as in FIG. Anchor 1510 also includes vertical openings on either side that are used to connect the tension rod to assembly 1500 and apply torque. In some embodiments, the anchor 1510 is modified to include several indentations along both sides in the vertical direction. These recesses are aligned with a plurality of protrusions protruding from the end cap 1520. When the end cap 1520 is disposed on both sides of the anchor 1510 in the vertical direction, the contact of the surface area between the end cap 1520 and the anchor 1510 is caused by the plurality of protrusions of the end cap 1520 and the plurality of depressions of the anchor 1510 in the vertical direction. Minimized to multiple contact points between. By reducing the multiple contact points between the anchor 1510 and the end cap 1520, this design leads from the anchor 1510 to multiple vertical assembly components and ultimately to the tension rod 1590 that connects to the assembly 1500. Reduce the amount of energy that can be transmitted. To further reduce energy transfer, some embodiments incorporate multiple plugs within multiple recesses. The plurality of plugs are made from energy or vibration absorbing material. In some such embodiments, the plurality of protrusions of the end cap 1520 are pressed against the plurality of plugs, and the plugs are formed by the plurality of protrusions of the end cap 1520 and the vertical recesses of the anchor 1510. Buffer contact between. In this configuration, contact between the end cap 1520 and the anchor 1510 is again minimized to a plurality of contact points between the plurality of protrusions of the end cap 1520 and the plurality of vertical recesses of the anchor 1510. An additional advantage is that there are a plurality of energy absorbing plugs between the contact points. FIG. 17 illustrates a plug 1710 in the vertical recess of the anchor, according to some embodiments.

  A first pair of vibration absorbing bushings 1530 disposed adjacent to the end cap 1520 reduces transmission of additional energy, particularly any energy transmitted from the anchor 1510 to the end cap 1520. These bushings 1530 are made from rubber, plastic, or other energy absorbing material. Thus, any energy transferred from the anchor to the end cap is attenuated or completely absorbed by the bushing 1530.

  The first pair of washers 1540 are disposed on the bushing 1530. Washer 1540 serves to distribute the load applied to bushing 1530 by a plurality of vertical clamping elements of assembly 1500.

  The plurality of vertical clamping elements begins with a tension bolt 1550 and a first outer nut 1560. A cross section of tension bolt 1550 is provided in FIG. As seen in FIG. 18, the tension bolt 1550 has a large top 1810, a lower half extension with an outer thread 1820, and a vertical cavity or hollow shaft with an inner thread 1830. The vertical cavity extends the entire length of the bolt 1550. An opening located in the middle of the large top 1810 provides an entrance from the top of the bolt 1550 to the vertical cavity, and a complementary opening at the opposite end of the bolt 1550 from the bottom of the bolt 1550 to the vertical cavity. Providing an entrance. As described below, the cavity and thread 1830 is a means of connecting the tension rod 1590 to the entire assembly 1500.

  Bolt 1550 is inserted into the vertical opening at the top of anchor 1510 such that a portion of the lower half extension of tension bolt 1550 passes through the vertical opening below anchor 1510. The first outer nut 1560 is used to fix the bolt 1550 to the anchor 1510. Once installed, the bolt 1550 serves as a receiver for the connection of the tension rod 1590, and in combination with the anchor 1510, the bolt 1550 further serves as a torsion block, whereas the tension rod 1590 provides torque. It is done.

  In some embodiments, the extension or body of the lower half of the tension bolt 1550 has a perimeter that does not contact the interior of the anchor 1510 when the tension bolt 1550 is inserted into the anchor 1510. This is another design aspect that further reduces the transfer of energy from the anchor 1500 to the tension bolt 1550 and ultimately to the tension rod 1590 that connects to the tension bolt 1550. In other words, the bolt 1550 never makes direct contact with the anchor 1550. Therefore, the energy absorbed by the anchor 1510 from the drum head is transmitted only to the end cap 1520 and the bush 1530. Each of the end cap 1520 and bushing 1530 provides energy attenuation or absorption before any potential for indirect transmission into the bolt 1550 and then into the tension rod 1590 occurs.

  The tension rod 1590 is a long tubular extension with a specialized connection head at each end of the rod 1590. FIG. 19 shows a tension rod 1590 of some embodiments and further provides a partial cross-sectional view that better shows the coupling heads at both ends of the tension rod 1590. The connecting head at the upper end of the tension rod 1590 includes a hollow shaft having a hex nut 1910, an outer thread 1920, and an inner thread 1930. The lower connection head includes an outer thread 1940 that is opposite or opposite to the upper outer thread 1920. The lower connection head also includes a hollow shaft having an inner thread 1950 opposite or opposite to the upper inner thread 1930.

  Opposite outer threads 1920 and 1940 provide a vise-like function in connection with tension bolt inner thread 1830. Specifically, when the tension rod 1590 is rotated in the first direction, the outer thread 1920 at the upper end is the inner thread 1830 of the first tension bolt fixed to the first anchor connected to the top shell mount. On the other hand, the outer thread 1940 at the lower end is simultaneously screwed to the inner thread 1830 of the second tension bolt fixed to the second anchor connected to the bottom shell mount. This pulls the first anchor closer to the second anchor, which in turn increases the pressure applied to the drum shell disposed between the top shell mount and the bottom shell mount. By rotating the tension rod 1590 in the opposite second direction, the outer threads 1920 and 1940 of the tension rod 1590 are unscrewed from the inner threads 1830 of the tension bolt 1550, thereby allowing the top and bottom shell mounts to The distance increases and the pressure on the drum shell decreases.

  The connection of one end of the tension rod 1590 to the tension bolt 1550 is best illustrated by the partially cutaway view of FIG. As shown in FIG. 20, tension bolt 1550 passes through anchor 1510 and a first outer nut 1560 is attached to the outer thread of the lower half extension of bolt 1550. A second pair of washers 1570 is then placed on the top of the tension bolt 1550 and the lower surface of the first outer nut 1560. A second outer nut 1585 secures one of the second pair of washers 1570 to the first outer nut 1560. The tension rod 1590 is then tensioned bolt 1550 until the outer threaded end 1920 of the tension rod 1590 contacts the inner thread 1830 within the vertical cavity (not shown in FIG. 20) of the tension bolt 1550. Is inserted upward through the lower vertical opening. At this point, the hex nut 1910 or body of the tension rod 1590 can be used to screw the tension rod 1590 to the inner thread of the tension bolt 1550, thereby connecting the two structures together. As explained above, tension rods 1590 are connected to different tension bolts 1550 at both ends, which tension bolts 1550 are themselves connected to different anchors 1510, which in turn are top shell mounts and Connected to bottom shell mount. Each time the tension rod 1590 is rotated, the tension rod 1590 is further pushed into the tension bolt 1550 connected to both ends of the tension rod 1590, thereby shortening the distance separating the anchor 1510 connected to the tension bolt 1550. Accordingly, the distance separating the top shell mount and the bottom shell mount to which the anchors 1510 are connected is shortened. Hex nut 1910 is provided to assist tension rod 1590 in applying torque to tension bolt 1550. This allows the user to dial the pressure on the drum shell by finely adjusting the distance between the top shell mount and the bottom shell mount of the drum shell.

  The position of the tension rod 1590 within the tension bolt 1550 can be fixed using a lockdown bolt 1580. Lockdown bolt 1580 passes through a vertical opening along the top surface of tension bolt 1550. Lockdown bolt 1580 has a large top and a vertical extension with an outer thread that is screwed to inner thread 1930 of tension rod 1590. To fix the position of the tension rod 1590, the lockdown bolt 1580 is screwed to the inner thread 1930 of the tension rod 1590 until the large top of the lockdown bolt 1580 contacts the large top of the tension bolt 1550. In this position, lockdown bolt 1580 prevents further adjustment to tension rod 1590. In other words, the position of the tension rod 1590 within the corresponding tension bolt 1550 is fixed, thereby fixing the distance between two anchors 1510 that are aligned horizontally but separated vertically. The pressure applied to the drum shell attached by the top shell mount and the bottom shell mount connected to the anchor 1510 separated in the vertical direction is fixed.

  FIG. 21 shows the completed assembly with tension rod 1590 at both ends connected to different modified rod holders. This figure shows how rotating the tension rod 1590 in the first direction 2110 reduces the distance separating the rod holder, and rotating the tension rod 1590 in the opposite second direction 2120 separates the rod holder. It further shows how to increase the distance.

  Some embodiments also provide an improved drum lug holder assembly for further isolating and attenuating energy transferred from the drum head to the mount frame in a manner that does not interfere with drum shell resonance. Traditionally, lug holders have been designed to tension the drum head by securing a drum hoop (which houses the drum head) to the drum shell. In these conventional designs, one end of the lug holder assembly is directly connected to the drum shell and the other end is connected to a drum hoop that holds the drum head (ie, part of the shell mount). However, by connecting the conventional lug holder directly to the drum shell, the resonance of the drum shell is hindered and the potential of the resulting sound cannot be fully demonstrated. Further, by connecting the conventional lug holder directly to the drum shell, the horizontal force applied to the drum shell is increased. Specifically, once tension is applied to the drum head by the tension bolt (s) once in the vertical direction, the anchor mount bolt of the lug holder applies tension to the drum shell on the conventional lug holder. Apply a horizontal force like a vise to the drum shell. These horizontal forces necessitate increasing the rigidity of the drum shell material so that the drum shell is not deformed or cracked by the force applied by the lug holder. Therefore, conventional drum shells intended to accept direct coupling with the shell of the lug holder cannot be made of a less rigid material such as plastic, clay, or glass, up to its full potential You are not given the freedom to resonate.

  A redesigned improved lug holder assembly is provided herein to eliminate these obstacles with respect to the drum shell while retaining the purpose and function of the lug holder. The improved lug holder assembly of some embodiments is designed to not connect directly to the drum shell. Instead, the improved lug holder assembly couples the drum hoop holding the drum head to a modified tension ring located on one end of the drum shell. The Altimount structural frame or other structural frame includes a top drum shell mount (including a first drum hoop coupled to a first tension ring by one or more of the improved lug holder assemblies), and an improved lug holder. It can be used to connect to a corresponding bottom shell mount (including a second drum hoop connected to a second tension ring by one or more of the assemblies). In this manner, the drum head is coupled to the drum shell with only the top shell mount and the bottom shell mount in contact with the drum shell. Some embodiments provide an energy attenuation that further minimizes the possibility of transfer of energy from the drum head to the structural frame, whatever the structural frame is used to attach the drum head to the drum shell. Properties are brought to the improved lug holder assembly.

  FIG. 22 illustrates an improved lug holder assembly of some embodiments. The improved lug holder assembly includes an anchor 2210, anchor mounting hardware 2215, a vertical tension bolt 2220, a swivel nut 2230, and a lockdown bolt 2240. FIG. 23 provides a top view of the components of the improved lug holder assembly.

  Anchor mount hardware 2215 couples anchor 2210 to the modified tension ring. FIG. 24 shows a modified tension ring 2410 to which the anchor 2210 is coupled. As shown, the modified tension ring 2410 includes one or more vertical brackets 2420 that extend downwardly from the outer surface of the tension ring. Each vertical bracket 2420 has one or more openings 2425. Anchor 2210 is coupled to each such vertical bracket 2420 using anchor horizontal mounting hardware 2215. With the anchor 2210 secured to the modified tension ring 2410 in the horizontal direction, one or more vertical tension bolts 2220 are used to anchor the anchor 2210 to the drum hoop that houses the drum head (see reference marker 2510 in FIG. 25). ). It will be apparent that the coupling order can be reversed so that the anchor 2210 is first secured vertically to the drum hoop 2510 and horizontally to the modified tension ring 2410. In any case, the improved lug holder assembly connects the drum hoop 2510 to the tension ring 2410 to form one of the drum shell mounts. FIG. 25 shows the completed improved lug holder assembly connecting the drum hoop to the modified tension ring of FIG.

  Referring again to FIG. 22, the anchor 2210 is formed by two spheres connected to a cylinder. This configuration is illustrative of one embodiment of anchor 2210. Specifically, this configuration is for coupling anchor 2210 to a tension ring having a vertical mounting bracket that includes two openings that are aligned with the sphere of anchor 2210. If the orientation of the tension ring mounting bracket is different, the anchor 2210 may be reshaped to match the orientation of the tension ring mounting bracket. Thus, other alternative configurations are possible without affecting the function and usefulness of the improved lug holder assembly.

  Anchor 2210 includes a vertical cavity that extends the length of anchor 2210. The swivel nut 2230 is inserted and attached into the vertical cavity. In some embodiments, the swivel nut 2230 has an elongated bottom that holds the swivel nut 2230 within the lower sphere of the anchor 2210. The swivel nut 2230 further includes an inner thread to which the outer thread of the vertical tension bolt 2220 is screwed as shown by FIG. A vertical tension bolt 2220 is screwed to the swivel nut 2230 to secure the drum hoop 2510 to the modified tension ring 2410. Specifically, the vertical tension bolt 2220 first passes through an extruded hole extending along the vertical surface outside the drum hoop 2510 as shown in FIG. The outer thread of the vertical tension bolt 2220 is screwed to the inner thread of the swivel nut 2230. The lockdown bolt 2240 fixes the position of the vertical tension bolt 2220 in the anchor 2210. More specifically, the outer threaded lockdown bolt 2240 is screwed into the inner threaded opening (see reference marker 2225 in FIG. 23) at the rear of the sphere above the anchor 2210. As shown in FIGS. 22 and 23, the swivel nut 2230 has an outer thread on the lockdown bolt 2240 such that the tip of the lockdown bolt 2240 can contact the outer thread on the vertical tension bolt 2220. It includes a threadless opening 2235 that allows it to pass through. To facilitate this, the unthreaded opening of the swivel nut 2235 is mated with the inner threaded opening 2225 located at the rear of the sphere above the anchor 2210. As shown by FIG. 27, the outer thread of the lockdown bolt 2240 is screwed clockwise into the inner thread opening 2225 at the rear of the anchor 2210, thereby further rotating the vertical tension bolt 2220. A horizontal force is applied to the outer thread of the tension bolt 2220 in the vertical direction to prevent movement. Lockdown bolt 2240 may include Teflon at the tip or other material to contact and prevent damage to the outer threads of vertical tension bolt 2220. In some embodiments, the drum hoop 2510 includes a threaded opening in the protrusion through which the vertical tension bolt 2220 passes. A lockdown bolt may be used in addition to or instead of the lockdown bolt 2240 of the anchor 2210 to fix the vertical position of the vertical tension bolt 2220.

  The front surface of each sphere of anchor 2210 includes a horizontal cavity with an inner thread. As noted above with reference to FIG. 24, these horizontal cavities are aligned with openings 2425 along the vertical bracket 2420 extending from the modified drum tension ring 2410. Anchor mount hardware 2215 is used to secure anchor 2210 to vertical bracket 2420.

  FIG. 28A shows the completed configuration of the mounting hardware 2215 for the anchor 2210. The mounting hardware 2215 includes a horizontal tension bolt 2250, a spacer 2260, a damping member 2270, a gripped end cap 2280, and a connecting spacer 2290. The spacer 2260, the damping member 2270, the gripped end cap 2280, and the connecting spacer 2290 are positioned on both sides of the bracket in the vertical direction of the tension ring. Specifically, the connection spacer 2290 is disposed on both sides of the opening of the bracket in the vertical direction. The extruded portion on one side of the connecting spacer 2290 faces the vertical bracket. A small circular recess opposite the connecting spacer 2290 provides a guide for the protrusion on the gripped end cap 2280 that contacts the connecting spacer 2290. The protrusions on the gripped end cap 2280 reduce the possibility of energy transfer from the drum head to the tension ring and ultimately to the structural frame that compresses the drum shell. The damping member 2270 contacts the gripped end cap 2280 along the side surface having no protrusion. The damping member 2270 further assists in reducing the energy transmitted to the structural frame. As shown in FIG. 22, the spacers 2260 are positioned on both sides of the damping member 2270. In order to connect the anchor 2210 to the vertical bracket 2420 of the tension ring, as shown in FIG. Through the opening 2425, the horizontal tension bolt 2250 is screwed into one of the horizontal inner threaded horizontal cavities in front of each sphere of the anchor 2210.

  It should be noted that in some embodiments, the mounting hardware 2215 is contoured to be flush with the radius of the vertical bracket 2420 of the modified tension ring. The shape of parts 2260, 2270, 2280 and 2290 can be seen by the top view provided by FIG. 28B. In FIG. 28B, the spacer 2810, the damping member 2820, the gripped end cap 2830, and the connecting spacer 2840 positioned with respect to the inner radius of the vertical bracket 2420 of the modified tension ring have a convex shape. In contrast, the connecting spacer 2850, gripped end cap 2860, damping member 2870, and mount coupler plate 2880 positioned relative to the outer radius of the vertical bracket 2420 of the modified tension ring have a concave shape. Due to these specific contours for each set of vibration damping components in some embodiments, neither set of components is interchangeable with respect to their assembly into the vertical bracket 2420.

  FIG. 29 shows a side view of an improved lug holder assembly connected to a vertical bracket of a modified tension ring. As can be seen, the vertical brackets provide sufficient separation to allow the drum shell to resonate freely. In other words, there is nothing in contact with the drum shell other than the top shell mount and the bottom shell mount. The improved lug holder assembly connects the drum head to the modified tension ring to form a shell mount, and the structural frame (such as the Alti mount frame described above) is at a pressure specified by the user against the drum shell. Used to hold the drum shell between the top shell mount and the bottom shell mount.

  Thus far, an improved lug holder assembly has been described that functions in conjunction with an Ultimount structural frame or other structural frame. Here, the structural frame controls the amount of compression applied to the drum shell by the top and bottom shell mounts. In some embodiments, the improved lug holder assembly is adapted to function without such a separate structural frame. In particular, some embodiments provide an adaptive lug holder assembly that can function in a manner similar to a drum hoop or existing prior art lug holder that directly connects a shell mount containing the drum hoop to the drum shell. provide. In some such embodiments, the adaptive lug holder assembly is directly coupled to the drum shell at one end and directly to the drum hoop or shell mount that houses the drum hoop at the opposite end. Connected to In doing so, the adaptive lug holder assembly can itself be used to regulate compression into the drum shell, thereby allowing the vertical bracket described above with reference to FIGS. The need for an improved tension ring having and the need for a separate structural frame to compress the drum shell by controlling the force applied to the drum shell by the top and bottom shell mounts is eliminated. The adaptive lug holder assembly of some embodiments has a structural element that minimizes undesired energy transfer from the drum head to the lug holder assembly that provides energy isolation and damping. More improved than the holder assembly. The energy can distort the drum sound by causing rattling of the lag holder while the drum is playing, or otherwise creating an external sound.

  FIG. 30 provides a perspective view of an adaptive lug holder assembly of some embodiments that couples directly to the drum shell. FIG. 31 provides an alternative side view for an adaptive lug holder assembly.

  As can be seen in both figures, the adaptive lug holder assembly passes through the vertical tension bolt 3020 through a circular extruded portion 3055 along the outer vertical surface of the drum hoop or shell mount. And by connecting the outer thread of the vertical tension bolt 3020 directly to the inner thread of the swivel nut 3030 inserted into the assembly anchor 3010, directly connected to the drum hoop or shell mount. To do. In some embodiments, the circular extruded portion includes a threaded opening. The lockdown bolt can be screwed into the threaded opening so that the tip of the lockdown bolt can contact the outer thread of the vertical tension bolt 3020, thereby further rotating the vertical tension bolt 3020. prevent.

  The adaptive lug holder assembly also passes through a secondary bolt (not shown) from the inside of the drum shell through an opening along the surface of the drum shell, and the secondary bolt in the horizontal direction of the assembly anchor 3010. The drum shell is connected horizontally by screwing into a horizontal threaded cavity around the surface of the drum shell. Various energy absorption and sound isolation elements are positioned on both sides of the drum shell to reduce undesirable rattling and other sound distortions from the adaptive lug holder. The vertical tension bolt 3020 is used to adjust the amount of y-axis compression that the drum hoop (which houses the drum head) applies to the drum shell.

  As shown in FIG. 32, the structural elements for the adaptive lug holder assembly that connect directly to the drum shell include the improved lug holder of FIGS. 22-29 that connects to the vertical bracket of the modified tension ring. Very similar to the structural elements associated with an assembly. As previously shown, the elements include horizontal anchor bolts 3210, washers / spacers 3220, damping members 3230, gripped end caps 3240, connecting spacers 3250, anchors 3260, and lockdown bolts. 3270 and a vertical tension bolt (not shown). Anchor 3260 includes an inserted swivel nut having an inner thread for receiving an outer thread of a vertical tension bolt (not shown). In some embodiments, the elements 3220, 3230, 3240 and 3250 can be shaped to be coplanar with respect to the inside and outside radii of the surface of the drum shell, with the elements positioned inside the drum shell having a convex shape. And the element positioned outside the drum shell has a concave shape.

  In contrast to the structural similarities of the elements described above, the adaptive lug holder anchor 3260 and the horizontal anchor bolt 3210 are modified to fully connect the adaptive lug holder assembly directly to the drum shell. Has been. In some embodiments, the inner threaded mount coupler plate (reference marker 2880 in FIG. 28B) attached to each sphere of the compatible lug holder anchor 3260 is a front surface of each sphere of the compatible lug holder anchor 3260. Extends horizontally. Also, the horizontal anchor bolts 3210 extend outwardly from the interior of the drum shell to the inner threaded mount coupler plate extending horizontally from the front of each sphere of the adaptive lug holder anchor 3260. It is long enough to be present. FIG. 31 also shows a horizontal extender 3110 as seen on the modified tension ring 2410 and occupying the same space as the vertical bracket 2420 used with the improved lug holder anchor 2210 of FIGS. These horizontal extenders 3110 are elongated so that they extend the spheres of the adaptive lug holder outwardly away from the radial outer surface of the drum shell. This allows the outer thread of the vertical tension bolt 3020 to be screwed to the swivel nut 3030 so that the drum hoop (which houses the drum head) can be secured to the drum shell. Aligned with the inner thread of swivel nut 3030 inserted into the anchor.

  Referring again to FIG. 32, coupling the adaptive lug holder assembly directly to the drum shell positions the extruded portion of the coupling spacer 3250 so that it faces both sides of the hole along the surface of the drum shell. Accompany. Here, the holes in the drum shell are aligned with the horizontal cavities of the anchor 3260. A small circular recess opposite the connecting spacer 3250 provides a guide for the protrusion on the gripped end cap 3240 that contacts the connecting spacer 3250. The protrusion on the gripped end cap 3240 reduces the likelihood of energy transfer from the adaptive lug holder anchor 3260 to the horizontal mounting hardware that contacts the gripped end cap 3240 and compresses the drum shell on the x-axis. . Attenuation member 3230 is positioned to contact gripped end cap 3240 along a side having no protrusion, and washer / spacer 3220 is positioned to contact attenuation member 3230. The shaft of the horizontal anchor bolt 3210 is passed from the inside of the drum shell through the positioned mounting hardware, and the outer threads of the horizontal anchor bolt 3210 are aligned horizontally on the front of each sphere of anchor 3260. Screwed into the inner threaded cavity. As a result, the anchor 3260 is fixed to the outer surface of the drum shell. This process of securing the adaptive lug holder across the side of the drum shell is repeated for the number of improved lug holder assemblies required to connect the drum hoop or shell mount to the drum shell. Tension bolts (ie, 3020) are used to secure each anchor 3260 to a drum hoop that houses the drum head. Here again, the tension bolt 3020 passes through the opening along the peripheral surface of the drum hoop 3055. The outer thread of the vertical tension bolt 3020 is screwed to the inner thread of the swivel nut 3030 inserted into the vertical cavity of the anchor 3260. The y-axis compression force on the drum shell can be controlled by tightening or loosening the vertical tension bolt 3020. As previously indicated, swivel nut 3030 includes a threadless opening along one side of its shaft. This opening allows the outer thread of the lockdown bolt 3270 to pass so that the tip of the lockdown bolt 3270 can contact the outer thread of the tension bolt 3020 in the vertical direction. To facilitate this, the unthreaded opening of the swivel nut 3030 is aligned with the inner threaded opening located at the rear of the sphere above the anchor 3260. As shown by FIG. 32, the outer thread of the lockdown bolt 3270 is threaded clockwise into the rear inner thread opening of the sphere above the anchor 3260, thereby causing the vertical tension bolt 3020 to A horizontal force that prevents further rotating movement is applied to the outer threads of the tension bolt 3020 in the vertical direction.

Horizontal mounting hardware 3510 further includes an anchor plate 3570, an anchor gripped end cap 3580, and an anchor dampening member 3590 positioned on the same opening and outside the drum shell. Here again, these components 3570, 3580, 3590, together with the anchor 3310, can be shaped according to the shape of the drum shell, thereby having a concave shape in some embodiments. Horizontal mounting hardware provides energy isolation or attenuation that minimizes or eliminates energy transfer from the adaptive lug holder assembly to the drum shell. The main difference between the inner and outer components is the size of the structural element. Outer components 3570, 3580, and 3590 are larger, each having the same general shape as anchor 3310. In some embodiments, the shaft of each mounting bolt 3520 includes an element 3530 disposed inside the drum shell before each bolt shaft is screwed into the horizontal threaded cavity of the anchor 3310. , 3540, 3550 and 3560, an opening around the drum shell, and lengthened to provide sufficient length to pass through elements 3570, 3580 and 3590 located outside the drum shell. Similar to the horizontal extender 3110 shown in FIGS. 30-32, the adaptive anchor 3310 shown in FIGS. 33, 34, 35 and 36 is elongated along the front of the anchor. This raised portion of the anchor is found in the modified tension ring 2410 and occupies the same space as the vertical bracket 2420 used with the anchor 2210 of the improved lug holder of FIGS. In addition, the anchor dampening member 3590, anchor gripped end cap 3580, and anchor plate 3570 shown in FIG. 35 extend the adaptive anchor 3310 outwardly away from the radial outer surface of the drum shell. . These combined elements allow the upper and lower vertical tension bolts 3610 to be screwed to the swivel nut 3620 to secure the top and bottom drum hoops (accommodating the drum head respectively) to the drum shell. Align the outer threads of the upper and lower vertical tension bolts 3610 with the inner threads of the swivel nut 3620 pointing up and down inserted into the unthreaded vertical opening 3640 of the adaptive anchor 3310. .

With positioning. Here, the hole in the drum shell is aligned with the horizontal cavity of the anchor 3310. The small circular recess opposite the pair of isolation washers / spacers 3560 provides a guide for the protrusions on the pair of mount gripped end caps 3550 that abut the isolation washers / spacers 3560. The mount dampening member 3540 is positioned to contact the mount gripped end cap 3550 along the side having no protrusion, and the mount washer / spacer 3530 is positioned to contact the mount dampening member 3540. Further, coupling the adaptive lug holder assembly of FIG. 35 directly to the drum shell also involves positioning the extruded portion on one side of the anchor plate 3570 in a hole along the outer side of the drum shell. Here, the hole in the drum shell is aligned with the horizontal cavity of the anchor 3310. The protrusion of the anchor gripped end cap 3580 contacts a recessed guide on the opposite side of the extruded portion on the anchor plate 3570. The anchor dampening member 3590 is positioned to contact the anchor gripped end cap 3580 along the side having no protrusion, and the anchor 3310 is positioned to contact the anchor dampening member 3590. Horizontal anchor bolt 3520 is passed from the inside of the drum shell through the positioned mounting hardware and the outer thread of bolt 3520 is screwed into the horizontal inner threaded cavity of anchor 3310. The protrusions found on the mounted gripped end cap 3550 and the anchor gripped end cap 3580 shown in FIG. 35 cause the drum shell on the x-axis to contact the protruding end caps 3550 and 3580 from the adapted lug holder anchor 3310. It should be noted that energy is less likely to be transferred to the horizontal mounting hardware for compression.

  FIG. 36 illustrates vertical mounting hardware for coupling a modified anchor 3310 to a top and bottom drum hoop or shell mount, respectively, according to some embodiments. The modified anchor 3310 includes an upper vertical unthreaded opening 3640 for receiving a first set of vertical mounting hardware used to connect the top drum hoop or top shell mount to the anchor 3310.

Each vertical tension bolt 3610 passes through an extruded hole (see reference marker 3350 in FIG. 33) that extends along a vertical surface outside the drum hoop. The outer thread of the vertical tension bolt 3610 is screwed to the inner thread of either the upper or lower swivel nut 3620 inserted into the anchor 3310. The lockdown bolt 3630 fixes the position of either the upper or lower vertical tension bolt 3610 screwed into either the upper or lower swivel nut 3620 inserted into the anchor 3610. More specifically, the outer thread of any lockdown bolt 3630 is screwed into one of a pair of inner threaded openings 3650 on the outer surface of anchor 3310. As shown in FIG. 36, the upper and lower swivel nuts 3620 each include an unthreaded opening along one side of their shaft. The unthreaded openings may be provided for each of these lockdown bolts 3630 so that the tips of the upper and lower lockdown bolts 3630 can contact the outer threads of the upper and lower vertical tension bolts 3610. Allows the outer thread to pass. To facilitate this, the unthreaded openings in the upper and lower swivel nuts 3620 are mated with the upper and lower inner threaded openings 3650 located on the outer surface of the anchor 3310. Further, as illustrated by FIG. 36, the outer threads of a pair of upper and lower lockdown bolts 3630 are threaded into upper and lower inner thread openings 3650 in the outer surface of anchor 3310; This applies a horizontal force that prevents any further rotational movement of either the upper or lower vertical tension bolt 3610 to the outer threads of the pair of vertical tension bolts 3610. Lockdown bolt 3630 can include Teflon at the tip or other material to prevent damage to the outer threads of vertical tension bolt 3610 in contact.

  Accordingly, the adaptable lug holder assembly depicted in FIGS. 30-36 (with or without a modified anchor) allows the drum head to be in a drum shell without a separate structural frame, such as an Ultimount structural frame. Can be used to link. The adaptive lug holder assembly continues to provide energy attenuation advantages over prior art lug holders. In particular, the adaptive lug holder assembly of some embodiments minimizes the amount of energy transferred from the drum head and drum shell to the lug holder by means of damping members positioned on opposite sides of the drum shell. This increases the resonance potential of the drum shell, while reducing or eliminating unwanted sound distortion that would otherwise result from the lag holder causing rattling during drum performance. Note that the shape of the adaptive lug holder anchor shown in FIGS. 30-36 can be manufactured to mimic many of the shapes of the casing from which many of the existing prior art lug holder anchors / casings are manufactured. Should. The mounting footprint for the adaptive lug holder anchor is shown as the vertical distance between the two horizontal mount anchor bolts 3210 (FIG. 32) and 3520 (FIG. 35). In addition, the arrangement in which the adaptive lug holder is attached to the drum shell is shown as the distance from either the upper or lower edge of the drum shell where the horizontal mount anchor bolt is located. The adaptive lug holder anchor shown in FIGS. 30-36 is widely compatible with existing lug holder anchors of the prior art for attachment and placement to the drum shell. This does not create any need to modify the adaptive lug holder anchor, adaptive lug holder mounting hardware, or drum shell, and the adaptive lug holder anchors and adaptive lugs listed herein. It allows the holder mounting hardware to serve as a fully compatible product of various prior art existing lug holder anchors. It would not be intended that every drum manufacturer would display falseness in the aesthetics of the shape of any proprietary (branded) existing lug holder casing known in the art.
