Definitions
- the disclosure relates to improvements in hardware for mounting percussion instruments, namely, acoustic and/or electronic drum suspension hardware.
- Electronic percussion instruments are known as alternatives to acoustic drums or other percussion instruments.
- An electronic percussion instrument typically includes a trigger pad equipped with various sensors designed to sense the features (e.g., location, intensity, etc.) of the playing impact on the trigger pad. These sensors send a corresponding electronic signal via a wire to a sound module that produces synthesized or sampled percussion sounds based on the electronic signal, which sounds are played through speakers connected to the sound module.
- Such electronic percussion instruments are known to be mechanically mounted on support structures, e.g., stands or kit frames, so that they may be played similarly to their corresponding acoustic instruments.
- problems arise due to this traditional mounting structure.
- First is in that residual vibration from the playing/performing energy may be transferred to the support structure through the traditional ridged mounting hardware. This residual vibration causes interference with the propagating electronic signal, causing the signal to inaccurately reflect the features of the playing impact. The sound produced by the synthesizer is accordingly impacted.
- Second, the feel and stick response from the electronic trigger pad with ridged mounting structure is significantly foreign to that of an acoustic drum mounted on a suspension system.
- Drumhead manufactures have made advancements to better emulate that of an acoustic drum feel and stick response, namely mesh head material. While this material improves the aforementioned feel characteristics, it still falls short of an acoustic drum and also introduced an undesirable trampoline stick response.

- Figures 1-10 illustrate exemplary percussion instrument mounts in accordance with aspects of the disclosed invention.
- a percussion instrument mount 10 comprises: a base 100 coupled to a swing arm 200 via a joint 300, the swing arm 200 configured to rotate about the joint 300 in response to a playing impact on a percussion instrument 20 coupled to the swing arm 200 via an instrument attachment mechanism 400; and a playing impact energy absorber 500 configured to absorb the rotation of the swing arm 200.
- the base 100 is also preferably coupled to a support structure 600, such as an instrument stand or kit frame, configured to support the percussion instrument 20 via the percussion instrument mount 10 on a playing surface, e.g., the ground or a stage.
- the impact energy absorber 500 preferably absorbs the playing impact by progressively dampening the swing via magnetic field resistance.
- the respective strengths and locations of one or more magnets located in the percussion instrument mount 10 produce a magnetic field that defines an equilibrium position for the swing arm 200. Movement of the swing arm 200 away from the equilibrium position (e.g., due to playing impact) is resisted by the magnetic field, which provides a restoring force tending the swing arm 200 back towards the equilibrium position.
- Mechanical resistance or frictional resistance may also be provided, for example at various points of rotation, so as to dissipate the playing impact energy. Accordingly, playing impact energy transferred from the drum to the base 100 is significantly reduced, if not eliminated altogether.
- the base 100 may comprise a first base portion 120 and a second base portion 140 having fixed relative positions with respect to each other.
- the first and second base portions may each comprise one or more grip elements 162 configured to secure the first and second base portions respectively to the support structure and/or an intermediate support 620.
- the support structure and/or intermediate support preferably comprises at least one rod 640 having at least one longitudinal groove 642 formed therein and configured to accept a corresponding grip element 162 so as to form a sliding joint 160 via which the first and second bases are configured to slide longitudinally along the rod so as to adjust their relative positions with respect to the rod and each other.
- the first and second bases are able to be removably joined with the rod via the sliding joint 160. That is to say that first and second bases may be slid off of and on to the rod via engaging respective grip elements and grooves.
- each groove and corresponding grip element together form a quasi-dovetail sliding joint, however, other sliding joints may be utilized without departing from the scope of the invention.
- Each of the first and second base portions also preferably includes one or more fasteners configured to secure the first and second base portions to the support structure and/or intermediate support in respective fixed positions relative thereto.
- the fasteners may, for example, comprise threaded fasteners whose contact can be tightened and loosened via screwing and unscrewing the fastener so as to forcibly contact a wall of the support structure and/or intermediate support and thereby provide and remove a frictional staying force.
- the base 100 comprises a unitary base (not shown), including at least one corresponding grip element similarly configured to secure the base 100 to the support structure and/or the intermediate support.
- the swing arm 200 may be a substantially rigid integral structure comprising: a first arm portion 220, a second arm portion 240, and a third arm portion 260 integrally connecting the first and second arm portions.
- the first arm portion 220 is coupled to the first base portion 120 via the joint 300 - and is thereby configured to swing or otherwise rotate about the joint 300 in response to the playing impact on the percussion instrument 20 coupled thereto.
- the joint 300 is preferably a hinge joint comprising a hinge bolt 320 that couples the first arm portion 220 to the first base portion 120 via respective through-holes 340.
- the hinge joint may provide mechanical resistance so as to dissipate playing impact energy.
- the hinge bolt 320 may further be provided with a deformable sheath
- the deformable sheath 360 positioned between the outer surface of the hinge bolt 320 and the inner surface of the through-hole 340 of the first arm portion 220.
- the deformable sheath 360 may engage appropriate pivot point structures of the joint 300.
- a pressure exerting element 380 may extend through the first arm portion 220 substantially perpendicular to the through-hole 340 so as to engage with the sheath 360 and exert pressure thereon. This deforms the sheath 360 so as to adjust the frictional resistance to rotation of the hinge bolt 320.
- the pressure exerting element is preferably a threaded element (e.g., an Allen fastener, etc.) so as to enable control of the amount of pressure - and therefore frictional resistance - applied.
- the third arm portion includes the instrument attachment mechanism 400, which is configured to attach the percussion instrument 20 to the swing arm 200.
- the instrument attachment mechanism 400 may comprise a slot 420 formed in the third arm portion, through which a fastener 440 secures mounting hardware 460 configured to accept the supported percussion instrument 20.
- the fastener may be loosened and tightened so as to permit the mounting hardware to slide within the slot, thereby repositioning the mounting hardware with respect to the swing arm 200 and thereby adjusting the angle properties of the mounted instrument.
- the second arm portion 240 extends distal to the first arm portion 220, and at least partially forms the playing impact energy absorber 500.
- the playing impact energy absorber 500 comprises at least one magnet pair 520, each magnet pair comprising a swing arm 200 magnet 522 and a base magnet 524.
- the at least one magnet pair is configured to impart the aforementioned magnetic restoring force, tending the swing arm 200 back towards the equilibrium position when the swing arm 200 is moved from the equilibrium position.
- the at least one magnet pair includes two magnet pairs.
- the magnetic restoring force may be repulsive and/or attractive. Arrangement of the respective magnets of the magnet pairs such that their like polarities face each other provides a repulsive magnetic restoring force.
- the weight of the instrument causes the swing arm 200 to move the swing arm 200 magnet and base arm magnet closer together than when in the equilibrium position.
- the repulsive magnetic force then reestablishes the swing arm 200 in the equilibrium position.
- Arrangement of the respective magnets of the magnet pairs such that their unlike polarities face each other provides an attractive magnetic restoring force.
- the weight of the instrument causes the swing arm 200 to move the swing arm 200 magnet and base arm magnet further apart than when in the equilibrium position.
- the attractive magnetic force then reestablishes the swing arm 200 in the equilibrium position. Accordingly, movement of the swing arm 200 away from the equilibrium position (e.g., due to playing impact) is resisted by the magnetic field caused by the at least one magnet pair, which provides the restoring force tending the swing arm 200 back towards the equilibrium position.
- the relative distance between the respective magnets of the magnet pair in equilibrium is adjustable so as to vary the repul si ve/attractive forces and/or the equilibrium position.
- the base magnet may include an outer thread that couples with an inner thread of a magnet aperture of the base 100, and a turnkey portion that facilitates a screwing motion for extending or retracting the base magnet from the magnet aperture thus altering the magnetic field (e.g., work force values).
- the support structure comprises at least one rod having at least one longitudinal surface groove 642 formed therein.
- a further grip element 162 couples the base 100 (or the intermediate support) to the support structure in the manner of the grip elements described herein.

- the at least one rod preferably forms a frame on which the percussion instrument mount 10 (and consequently, the percussion instrument 20) is mounted. Accordingly, a plurality of rods may be coupled together at various joints, which joints may be configured to permit the rods to rotate about their longitudinal axis relative to each other. The joints may further be configured to fix the rotational position of each rod. In some embodiments, frictional elements (e.g., screws) are utilized at the joint to fix the rotational position of each rod. In this manner, the playing position of the mounted percussion instrument 20 may be further adjusted.
- the base 100 is configured to couple to the support structure.

- the base 100 is further coupled to the swing arm 200 via the joint 300, which preferably comprises one or more hinge joints configured to permit the swing arm 200 to swing or otherwise rotate about the joint 300 in response to the playing impact on the percussion instrument 20 coupled thereto.
- the hinge joints may further provide mechanical resistance so as to dissipate playing impact energy.
- the swing arm 200 further includes the instrument attachment mechanism 400, which is configured to attach the percussion instrument 20 to the swing arm 200.
- the instrument attachment mechanism 400 may be configured to securely accept mounting hardware via which the instrument is supportable on the mount 10.
- the instrument attachment mechanism 400 may be slideably coupled to the swing arm 200, either directly or via an intermediate piece, such that its longitudinal position relative to the swing arm 200 (i.e., along the z-axis) may be adjusted. Accordingly, corresponding grip elements may be utilized in the manner similarly discussed herein so as to achieve this functionality.
- the instrument attachment mechanism 400 may also permit rotational adjustment about the x-axis and/or the y-axis so as to adjust the playing angle and/or additionally rotate/invert the drum 180 degrees for tuning the opposing drum head of the instrument without disengaging the instrument from the attachment mechanism 400. Such adjustment may be mechanically enabled either via the direct coupling or the indirect coupling.
- an intermediate piece is configured to couple the instrument attachment mechanism 400 to the swing arm 200, as well as to enable such adjustment.
- the playing impact energy absorber 500 may comprise: a dampening arm 560 configured to rotate about an intermediate hinge point 562; a swing arm coupler 570 configured to couple the dampening arm 560 to the swing arm 200 at respective terminal hinge points 564 and 566; a magnet block 580 configured to provide the magnetic restoring force.
- the swing arm coupler 570 preferably includes a first hinge structure 572 defining the terminal hinge point of the dampening arm 560.

- the swing arm sleeve preferably defines a hollow that is configured to accept the swing arm 200 therein such that the sleeve may be repositioned along at least a portion of the length of the swing arm 200. Accordingly, in at least some embodiments, the swing arm 200 and swing arm sleeve employ a sliding joint configuration. It is further preferable that the position of the swing arm sleeve on the swing arm 200 is fixable via a fastener, e.g., a screw. In this manner, the bias of the dampening arm 560 may be adjusted so as to improve sound quality of the mounted instrument.
- a fastener e.g., a screw
- the dampening arm 560 further includes an elongated aperture 564 that receives a third hinge structure 568 defining the intermediate hinge point.
- the third hinge structure is preferably repositionable within the elongated aperture so as to adjust the intermediate hinge point, thereby compensating for different shell construction/weight sonic properties of various percussion instrument 20s.
- the third hinge structure preferably couples the dampening arm 560 to the support structure and/or intermediate support via a dampening arm sleeve 570.
- the dampening arm sleeve is structurally similar to the swing arm sleeve - except that it couples the third hinge structure to the support structure and/or intermediate support.
- the variable third hinge structure regulates leverage (force) transferred to the magnet field, also effecting the equilibrium stabilization position.
- the dampening arm 560 is further coupled to the magnet block 580 at the opposite end from the swing arm coupler 570.
- the magnet block 580 preferably houses at least one magnet block magnet 582 that forms part of at least one magnet pair.
- the base 100 houses at least one corresponding base magnet opposite the magnet block magnet, the base magnet forming the other part of the at least one magnet pair.
- the magnetic forces of the at least one magnet pair defines the equilibrium position for the magnet block 580 (and consequently the swing arm 200).
- the at least one magnet pair is accordingly configured to impart the aforementioned magnetic restoring force, tending the dampening arm 560 / swing arm 200 back towards the equilibrium position when the swing arm 200 is moved from the equilibrium position.
- the at least one magnet pair includes two magnet pairs. As with the previously described magnet pairs, the equilibrium distances between the individual magnets may be adjustable.
- the playing impact cases the swing arm 200 to rotate about the joint 300.
- the rotation of the swing arm 200 is then translated to the dampening arm 560 via the swing arm coupler 570, which dampening arm 560 is thereby caused to rotate about the intermediate hinge point defined by the third hinge structure.
- the rotation of the dampening arm 560 then forces the magnet block 580 out of the equilibrium position, which results in the magnet pair providing the restoring force to the magnet block 580.
- the restoring force is then translated through the corresponding counter-rotation of the dampening arm 560 and the swing arm 200.
- the joint 300, and optionally, one or more of the hinge structures provide mechanical and/or frictional resistance so as to further dissipate the playing energy.
- the playing impact absorber may comprise a system in which opposing dampening arms are arranged on either side of the swing arm 200.
- the opposing dampening arms may each individually couple to the magnet block 580, the intermediate hinge, and the swing arm 200 in the manners described herein.

- the mounting hardware may comprise an instrument support element 462 configured to accept the instrument for support thereon.
- the instrument support element may, for example, comprise top and inner surfaces shaped to form a substantially flush fit with a drum exterior, as well as mounting apertures extending through the top surface and positioned so as to accept hardware components of the drum and thereby secure the drum to the instrument support element.
- the instrument support element may further be fixed to a rotational element 464 configured to couple the instrument support element to the swing arm 200 so as to rotate perpendicular to the plane of the rotation of the swing arm 200.
- FIGS 11 thru 13 illustrate exemplary embodiments in which non-magnetic restoring forces are utilized in accordance with the principles described herein.

- the playing impact energy absorber 500 may include restoring elements (e.g., magnets, bladders, foam, springs, elastic bands, etc.) positioned to one or both of a load side and a stabilizing side of the swing arm 200.
- restoring elements e.g., magnets, bladders, foam, springs, elastic bands, etc.
- the load side is the side to which the swing arm 200 initially moves in response to playing impact on the drum, and takes the initial load of the impact
- the stabilizing side is opposite the load side, and provides an additional restoring force.
- the elastic band type restoring element 598 may comprise a load-side elastic band restoring element 598a and/or a stabilizing-side elastic band restoring element 598b.
- Tension in the load-side elastic band 598a restoring element may be adjustably provided as follows: one end of the load-side elastic band 598a may be fixed to the swing arm 200; the intermediate portion of the load-side elastic band 598a may pulley -like engage a post 599 at the base 100; and the other end of the load-side elastic band 598a may be fixed to an end tensioner 599a in the support structure 600 (or alternatively, in the base 100).
- the position of the end tensioner 599a may be adjusted so as to increase and/or decrease tension in the load-side elastic band 598a. Such adjustability may be via fixedly repositioning the end tensioner 599a within a slide slot, or may be via fixedly rotating the tensioner to progressively wrap the load-side elastic band thereabout.
- the post 599 may alternatively or additionally comprise an intermediate tensioner 599b.
- Tension in the stabilizing-side elastic band 598b may be adjustably provided in similar fashion via one or more end tensioners 598a and/or intermediate tensioners 599b.

- load and stabilizing sides may include the same type of restoring element, or may include different types of restoring elements. This is illustrated, for example, in Figure 11, which shows the load side having the inflatable bladder 592 and the stabilizing side having the foam cushion 594 types of restoring elements. Although not expressly shown, any other combination of restoring elements (magnetic and/or non magnetic) may be utilized without departing from the scope of the invention.
- mount 10 is described herein as mounting drums 20, the principles of the invention may also be applied to cymbals and other percussion instruments (not shown).
- Figure 14 illustrates an exemplary embodiment in which the principles of the invention are applied to a cymbal mount 10a.
- a base 100a may be coupled to a swing arm 200a via a joint 300a.
- the swing arm 200a may be configured to rotate about the joint 300a in response to a playing impact on the cymbal coupled to the swing arm 200a via a cymbal attachment mechanism 400a.
- a playing impact energy absorber 500a may be configured to absorb the rotation of the swing arm 200a.
- the base 100a is also preferably coupled to a support structure 600a, such as an instrument stand or kit frame, configured to support the cymbal via the percussion instrument mount 10a on a playing surface, e.g., the ground, stage or kit.
- the impact energy absorber 500a preferably absorbs the playing impact by progressively dampening the swing via magnetic field resistance.
- the respective strengths and locations of one or more magnets 522a, 524a located in the cymbal mount 10a produce a magnetic field that defines an equilibrium position for the swing arm 200a. Movement of the swing arm 200a away from the equilibrium position (e.g., due to playing impact) is resisted by the magnetic field, which provides a restoring force tending the swing arm 200a back towards the equilibrium position.
- Mechanical resistance or frictional resistance may also be provided, for example at various points of rotation, so as to dissipate the playing impact energy. Accordingly, playing impact energy transferred from the cymbal to the base 100a is significantly reduced, if not eliminated altogether.
- non magnetic restoring forces e.g., spring forces, elastomer forces or combinations of dislike mechanical forces
- the non-magnetic restoring force may be repulsive and/or attractive, and may be provided by one or more restoring elements, as discussed herein.
- the cymbal mount 10a is configured such that the cymbal is moveable along the swing arm 200a, towards/away from the hinge 300a, so as to alter the leverage with respect to the impact energy absorber 500a.
- the cymbal attachment mechanism 400a may couple the cymbal to the swing arm 200a via an actuator 480.
- the actuator 480 may be positioned internal to the swing arm 200a.
- the actuator 480 may include a longitudinal screw portion 482 configured to freely rotate therein, as well as a threaded nut portion 484 accepting the screw portion 482 therein such that rotation of the screw portion 482, via an exposed end thereof, causes the nut portion 484 to longitudinally traverse the screw portion 482.
- the nut portion 484 may be coupled (integrally or non- integrally) to a central shaft 486 of the cymbal attachment mechanism 400a. Rotation of the screw portion 482 may therefore move the cymbal towards/away from the hinge 300a, altering the sonic properties of the cymbal.
- the swing arm 200c and base 100c of the mount may comprise a clam shell arrangement, in which, opposite the hinge 300c, each engages the floor leg 490c in a respective through aperture.
- the base 100c may fixedly engage the floor leg 490c, while the swing arm 200c freely engages the floor leg 490c, such that a lug (or other structural portion) of the drum rests on top of the swing arm, forcing it towards the base.
- the leg mount 10c may support the drum leg 490c on the floor, the swing arm 200c fixedly coupling to the drum leg 490c while the base 100c rests on the floor or other support.
- the restoring force may be provided by any the energy absorber utilizing one or more of the restoring elements discussed herein, or principles thereof, including magnetic and non-magnetic restoring elements, and is opposite the force exerted by the drum resting on top of the swing arm. Accordingly, the leg mount 10c ultimately supports the drum and absorbs the playing impact via the energy absorber.
