BACKGROUND
Field of Inventions

The field of this application and any resulting patent is drum coupling assemblies.

Description of Related Art

Many percussionists, such as drummers, put various materials and objects against a drumhead for the purpose of adding to, changing and/or controlling the sound of a drum. Common objects placed against a drumhead to achieve certain sounds, tones and/or effects are: tape, gel, foam, wallets, cell-phones, tambourines, shakers, rattles, cymbals, etc.

An object may produce a desired tone when initially placed at a certain location with a certain orientation and/or pressure against a drumhead. However, the object will often not stay where it was initially placed while the drum is being played due to the angle of the drumhead surface, vibrations of the drum, and/or the object being struck by the percussionist who is playing the drum. An object moved into an undesired position and/or orientation on a drumhead can produce undesired tones, disrupt the playing of the drum, and/or fall off the drum completely.

Adhesives are often used to dampen a drum's tone and/or fasten one or more objects to a drumhead of the drum. However, when adhesives are used, repositioning those objects can be difficult, the drumhead may get damaged, the full vibration and resonance of the drum would be impeded, and adhesives eventually lose their functionality as they collect dust and other particulates. For percussionists these issues present some serious problems because percussionists may desire to change and/or modify the sounds, tones, and effects coming from their drums quickly and easily depending on the piece of music they are playing and/or the venue where they are playing it because qualities and dimensions of the venue may affect perception of sound produced from the drum. Qualities of a venue may include building materials and ambient surroundings. Dimensions of a venue may include size and shape.

Some specific accessories are designed to produce certain percussive effects and stay in place with the use of brackets or mounts, which attach to a drum rim or hoop. However, these accessories have shortcomings, e.g., limitation to one type of effect/use and/or limited positioning.

Various drum coupling assemblies and methods for coupling percussive effect objects to drumheads have been proposed and utilized, including some of the methods and structures disclosed in some of the references appearing on the face of this application. However, those methods and structures lack the combination of steps and/or features of the methods and/or structures covered herein. Furthermore, it is contemplated that certain of the methods and/or structures disclosed herein solve many of the problems that prior art methods and structures have failed to solve. Also, the methods and/or structures disclosed herein have benefits that would be surprising and unexpected to a hypothetical person of ordinary skill with knowledge of the prior art existing as of the filing date of this application.

Various terms as used herein are defined below, and the definitions should be adopted when construing the claims that include those terms, except to the extent a different meaning is given within the specification or in express representations to the Patent and Trademark Office (PTO). To the extent a term used in a claim is not defined below or in representations to the PTO, it should be given the broadest definition persons having skill in the art have given that term as reflected in at least one printed publication, dictionary, or issued patent.

2. Selected Definitions

Certain claims include one or more of the following terms which, as used herein, are expressly defined below.

The term “abutted against” as used herein is defined as being positioned adjacent to and either physically touching or pressing against, directly or indirectly. For example, a first object may be abutted against a second object such that the second object is limited from moving in a direction of the first object. Thus, a clamp may have a terminal abutted against a drum hoop. Also, a thumb screw may have a portion abutted against a drum hoop.

The term “aligning” as used herein is a verb that means manufacturing, forming, adjusting, or arranging one or more physical objects into a particular position. After any aligning takes place, the objects may be fully or partially “aligned.” Aligning preferably involves arranging a structure or surface of a structure in linear relation to another structure or surface; for example, such that their borders or perimeters may share a set of parallel tangential lines. In certain instances, the aligned borders or perimeters may share a similar profile. Additionally, apertures may be aligned, such that a structure or portion of a structure may be extended into and/or through the apertures.

The term “aperture” as used herein is defined as any opening in a solid object or structure, e.g., drum, drum hoop, clamp, clamp terminal, clamp body, cord lock, or tubular. For example, an aperture may be an opening that begins on one side of a solid object, e.g., drum hoop, clamp, clamp terminal, clamp body, cord lock, or tubular, and ends on the other side of the object. An aperture may alternatively be an opening that does not pass entirely through an object, but only partially passes through, e.g., a groove. An aperture can be an opening in an object, e.g., drum, drum hoop, clamp, clamp terminal, clamp body, cord lock, or tubular, that is completely circumscribed, defined, or delimited by the object itself. Alternatively, an aperture can be an opening formed when one object, e.g., drum, drum hoop, clamp, clamp terminal, clamp body, cord lock, or tubular, is combined with one or more other objects or structures. An aperture may receive an object, e.g., cord or pin of a cord lock. For example, a cord may be received in an aperture of a terminal or a body of a clamp or pin and/or body of a cord lock. Additionally, a restraining portion of a cord may be received within an opening of a drum hoop.

The term “assembly” as used herein is defined as any set of components that have been fully or partially assembled together. A group of assemblies may be coupled to form a solid body having an inner surface and an outer surface.

The term “clamp” as used herein is defined as an assembly capable of being removably coupled to another object using pressure. Parts of a clamp may be pressed against a drum and/or a drum hoop. A clamp is capable of being removably coupled to a drum and/or a drum hoop. A clamp may have a body, a first terminal, and a second terminal. A clamp may have a body, a first terminal, and a second terminal that are a unitary single molded rigid piece. A clamp may be molded, 3D-printed, or carved from a single piece of material, e.g., plastic, carbon fiber, metal, or wood. Further, a clamp may include a thumb screw. A clamp may have a body capable of being abutted against an edge, e.g., lip or rim, of a drum hoop of a drum. A clamp may have a body capable of being abutted against an upper edge of a drum hoop. A clamp may have a body capable of being abutted against a lower edge of a drum hoop. A clamp may have a first terminal extending from a first end of a body of the clamp. A clamp may have a second terminal extending from a second end of a body of the clamp. A clamp may have the shape of a block-letter “C” or “G.” A clamp may have a terminal threadably coupled to a thumb screw. A clamp may include one or more apertures disposed laterally therethrough. A body of a clamp may include one or more apertures disposed laterally therethrough. A terminal of a clamp may include one or more apertures disposed laterally therethrough. A clamp may have a screw pressed against an outer surface of a drum hoop and a terminal pressed against an inner surface of the drum hoop. A clamp may be a G-clamp, a C-clamp, a clip, a latch, a hook, fasteners, or a lock.

The term “cord” as used herein used is defined as an elongated and flexible structure. Examples of a cord may be a bungee, a rubber band, a strap, a rope, a string, a cable, a wire, and/or a ribbon. A cord may be cylindrical. A cord may be constructed from resilient and/or elastic material, e.g., plastic, latex, rubber, nitrile rubber, butyl rubber, silicone, and/or neoprene. A cord may be resiliently deformed, e.g., bent or stretched by being pulled and/or pushed. Thus, a cord deformed from an original state may return to the original state. Pulling and/or pushing a cord may increase tension, e.g., force, on the cord. A cord may be capable of ingress and/or egress through an aperture of an object, e.g., clamp, clamp terminal, clamp body, or cord lock. A cord may have various structures, e.g., clip, pin, tape, sleeve, latch, hook, fastener, or lock, coupled to an end of the cord that, in some cases, may inhibit the end from egress through a portion of a clamp. A cord may have various materials or chemicals, e.g., adhesive, glue, or epoxy, disposed on an end of the cord and a portion of a clamp that, in some cases, may inhibit the end from egress through the portion. A cord may be slidably coupled to a clamp. A cord may have an outer diameter greater than a diameter of a surface defining an aperture disposed through a clamp. A cord may have an outer surface that is in physical contact with a surface defining an aperture through a clamp. Physical contact between an outer surface of a cord and a surface defining an aperture through a clamp may inhibit the cord from being slid through the aperture. When pulled, a cord would have a diameter smaller than a diameter of a surface defining an aperture disposed through a clamp. A cord may be extended, e.g., laced, through an aperture disposed in a clamp. A cord may have an end capable of being tied into a knot (see, e.g., 310, FIGS. 1-4 and 15-19). A cord may have a knot capable of being abutted against a clamp. A cord may have a knot capable of inhibiting the cord from being slid out of a clamp. A cord may be slidably coupled to a cord lock. One or more portions of a cord may be disposed between two portions of an inner surface of a drum hoop. One or more portions of a cord may be disposed within an aperture of a drum hoop. A cord may have a restraining portion between a first clamp and a second clamp. A cord may have a restraining portion disposed within an aperture of a drum hoop. A cord may have a restraining portion removably coupled to a percussive effects object. A cord may have a restraining portion disposed substantially parallel to a drumhead. A cord may be in physical contact with and/or abutted against a drumhead. Preferably, a cord is not in physical contact with a drumhead. A cord may be disposed as close as 1.0, 2.0, 3.0, 4.0 or 5.0 millimeters or as far as 1.0, 2.0, 3.0, or 4.0 centimeters or farther from a drumhead. A portion of a cord may be said to be disposed between an edge of a drum hoop and a drumhead if the portion is disposed between the drumhead and a plane that is tangent to the edge and parallel to the drumhead. Additionally, a portion of a cord may be said to be disposed between an edge of a drum hoop and a drumhead if the portion is disposed at a first distance from the drumhead less than a second distance from the edge to the drumhead.

The term “cord lock” as used herein used is defined as a device configured for coupling to a cord. A cord lock may be coupled to a cord and may be abutted against a clamp. A cord lock may include a tubular body, a pin disposed concentrically within the tubular body, and a spring disposed between the pin and the tubular body. A cord lock may have a pin slidably coupled to a tubular body. A cord lock may have a spring abutted against a tubular body and a pin such that the spring may cause the tubular body and the pin to be biased away from each other. A cord lock may have apertures disposed through a tubular body and a pin in which the apertures are capable of being aligned. A cord lock may have apertures through which a cord may be capable of slidable ingress or egress, or both. When a pin and a tubular body of a cord lock are biased away from each other, the pin and the tubular body would be pressed against a cord. Accordingly, the cord would be inhibited from ingress or egress through the apertures of the pin and the tubular body.

The term “coupled” as used herein is defined as directly or indirectly connected, attached, or part of. A first object may be coupled to a second object such that the first object is positioned at a specific location and orientation with respect to the second object. For example, a cord may be coupled to a clamp. A first object may be either permanently, removably, slidably, and/or threadably coupled to a second object. Two objects may be removably coupled to each other via knots, threads, tape, latches, hooks, fasteners, locks, male and female connectors, clips, clamps, and/or surface-to-surface contact. For instance, a percussive effects object would be removably coupled to a drumhead of a drum and a cord of a drum coupling assembly if the percussive effects object is positioned adjacent to or abutted against the drumhead and the cord. In another example, a clamp and a drum hoop may be removably coupled to each other such that the clamp may then be uncoupled and removed from the drum hoop. In addition, a cord may be coupled to a clamp such that the cord and the clamp may then be uncoupled. Two objects may be slidably coupled together, e.g., where an inner aperture of one object is capable of receiving a second object. For example, a cord extending through an aperture of a clamp may be slidably coupled to the clamp. An outer surface of the cord may be abutted against an inner surface that defines the aperture of the clamp. The cord may be pulled or slid through the aperture of the clamp. As the cord is pulled, the outer surface of the cord may have a diameter that is smaller than a diameter of the inner surface that defines the aperture of the clamp. In another example, a body and/or terminal of a clamp and a body and pin of a cord lock having apertures through which a cord may be slid. Additionally, two objects may be capable of being threadably coupled, e.g., where a threaded outer surface of one object is capable of engaging with a threaded inner surface of another object. Threadably coupled objects may be removably coupled. Accordingly, a thumb screw may be threadably coupled to a terminal of a clamp where a threaded inner surface, e.g., box threads or female threads, of the terminal may be engaged with a threaded outer surface, e.g., pin threads or male threads, of the thumb screw.

The term “cylindrical” as used herein is defined as shaped like a cylinder, e.g., having straight parallel sides and a circular or oval or elliptical cross-section. A cylindrical body or structure, e.g., drum, drum hoop, thumb screw, or cord lock, may be completely or partially shaped like a cylinder. A cylindrical body, e.g., drum, drum hoop, thumb screw, or cord lock, that has an inner or outer diameter that changes abruptly may have a “flange” e.g., radial face, rim, or lip, extending toward or away from the center axis (see, e.g., 312, FIG. 9). Additionally, a cylindrical body, e.g., drum, drum hoop, rim, thumb screw, or cord lock, may have a flange that is tapered or radiused. A cylindrical body may have an aperture extending through the entire length of the body to form a hollow cylinder that is capable of permitting another body, e.g., clamp, cord, and/or percussion effects object, to be extended or passed through.

The term “drum” as used herein is defined as an instrument capable of being struck, e.g., by objects, sticks, and/or hands, to produce sound. A drum may include a drum shell, a drum hoop, and a drumhead.

The term “drumhead” as used herein is defined as a membrane covering an opening of a drum shell. A drumhead may be planar. A drumhead may have a plane parallel to a restraining portion of a cord.

A drum hoop may have an inner surface that defines a perimeter. A drum hoop may have an inner surface that defines an opening therethrough. A drum hoop may have an upper edge. In some cases, a drum hoop may be facing the ground; therefore, the drum hoop may have a lower edge. A drum hoop may have an edge capable of being abutted against a body of a clamp. A drum hoop may have an inner surface capable of being abutted against a terminal of a clamp. A drum hoop may have an outer surface capable of being abutted against a screw of a clamp.

The term “edge” as used herein is defined as any line or border at which any surface terminates, or any line at which two surfaces of a solid object meet. For example, a drum hoop may have an inner surface and an outer surface forming an edge where they meet.

The terms “first” and “second” as used herein merely differentiate two or more things or actions, and do not signify anything else, including order of importance, sequence, etc.

The term “holding” as used herein is a verb that means as keeping, e.g., sustaining, retaining, confining, bearing, and/or supporting, an object in one position. For example, a clamp having a terminal coupled to an inner surface of a drum hoop of a drum may hold a portion of a cord (coupled to the terminal) within a perimeter defined by the inner surface of a drum hoop. In other words, the terminal may be holding the portion of the cord in an opening of the drum hoop.

The term “orthogonal” as used herein is defined as at an angle ranging from 85° or 88 to 92° or 95°. Two structures that are orthogonal to each other may be perpendicular and/or tangential to each other.

The term “parallel” as used herein is defined as having sides that, in some cases, do not intersect or intersect to form an angle ranging from 1°, 2°, or 3° to 4° or 5°.

The term “providing” as used herein is defined as making available, furnishing, supplying, equipping, or causing to be placed in position.

The term “percussive effects object” as used herein is defined as a structure capable of being removably coupled to a cord and/or a drumhead of a drum. A percussive effects object may include one from a group of tambourines, shakers, rattles, cymbals, chains, toys, or pieces of metal, foam, fabric, or strings, etc.

The term “surface” as used herein is defined as any face of a structure. A surface may also refer to that flat or substantially flat area extending radially around a cylinder which may, for example, be part of a drum or drum hoop. A surface may also refer to that flat or substantially flat area that extend radially around a cylinder which may, for example, be part of a drum, a drum hoop, a drumhead, a terminal of a clamp, or a body of a clamp. A surface may have irregular contours. A surface may be formed from components, e.g. a drum hoop, a drumhead, a terminal of a clamp, or a body of a clamp, coupled together. Coupled components may form irregular surfaces.

The term “terminal” as used herein is defined as a structure of a clamp capable of being abutted against a surface of a drum hoop. A terminal may extend from a body of a clamp. A terminal and a body of a clamp may be unitary. A terminal of a clamp may be disposed parallel to a surface of a drum hoop. A terminal may include one or more apertures disposed laterally therethrough. A terminal may be threadably coupled to a thumb screw. A terminal may be configured to be disposed within a perimeter defined by an inner surface drum hoop. A terminal may be configured to be disposed in an aperture defined by an inner surface drum hoop.

The term “threaded” as used herein is defined as having threads. Threads may include one or more helical protrusions or grooves on a surface of a cylindrical object. Each full rotation of a protrusion or groove around a threaded surface of the object is referred to herein as a single “thread.” Threads formed on an inner surface of an object, e.g., terminal of a clamp, may be referred to as box threads or female threads. Threads formed on an outer surface of an object, e.g., thumb screw, may be referred to as pin threads or male threads. A threaded assembly may include a “threaded portion” wherein a section of the threaded assembly includes threads, e.g., pin threads or box threads. In certain cases, a threaded portion of a structure may be removably coupled to a threaded assembly.

The term “screw” as used herein is defined any structure that includes threads used for coupling two objects together. A screw may be capable of threadable ingress or egress through a terminal of a clamp. A thumb screw may be turned clockwise. A thumb screw may be turned counter-clockwise. A thumb screw may threadably extend through a terminal of a clamp. A thumb screw may be abutted against an outer surface of a drum hoop. A thumb screw may be threadably retracted through a terminal of a clamp.

The term “tubular” as used herein is defined any structure having an inner surface and an outer surface. A tubular may have an aperture disposed therethrough. Preferably, a tubular is cylindrical. However, any or all tubulars of an assembly, e.g., drum, drum hoop, or cord lock, may have polygonal cross-sections, e.g., triangular, rectangular, pentagonal, hexagonal, or octagonal.

The term “unitary” as used herein defined as having the nature, properties, or characteristics of a single unit. For example, a body and a terminal that are individual parts of a clamp may be unitary in the sense they are not separate but rather are formed, e.g., molded, 3D-printed, or carved, from a single piece of material, e.g., plastic, carbon fiber, metal, or wood.

The terms “upper,” “lower,” “top,” “bottom” as used herein are relative terms describing the position of one object, thing, or point positioned in its intended useful position, relative to some other object, thing, or point also positioned in its intended useful position, when the objects, things, or points are compared to distance from the center of the earth. The term “upper” identifies any object or part of a particular object that is farther away from the center of the earth than some other object or part of that particular object, when the objects are positioned in their intended useful positions. The term “lower” identifies any object or part of a particular object that is closer to the center of the earth than some other object or part of that particular object, when the objects are positioned in their intended useful positions. For example, a drum may have an upper end and a lower end. Additionally, a cylindrical object, e.g., drum, drum hoop, thumb screw, or cord lock, may have an upper portion and a lower portion. The term “top” as used herein means in the highest position, e.g., farthest from the ground. The term “bottom” as used herein means in the lowest position, e.g., closest the ground. For example, a cylindrical object, e.g., drum, drum hoop, thumb screw, or cord lock, may have a top portion and a bottom portion.

FIGS. 3, 4, 17, and 18 illustrate perspective and side views of exemplary drum coupling assemblies 100. Like elements may be indicated by like reference numerals.

Referring to FIGS. 3, 4, 17, and 18, a drum coupling assembly 100 may include a first clamp 102a, a second clamp 102b, and a cord 104. The first clamp 102a may have a body 302a, a first terminal 304a, a second terminal 304b, and a thumb screw 306a. The first terminal 304a and the second terminal 304b may each extend from the body 302a. The thumb screw 306a may threadably extend through the second terminal 304b.

Furthermore, the cord 104 may have a first end portion slidably coupled to the clamp 102a. The first end portion of the cord 104 may extend through apertures 308a-c disposed in the first clamp 102a. Also, the cord 104 may have a second end portion slidably coupled to the clamp 102b. The second end portion of the cord 104 may extend through apertures 308d-f disposed in the second clamp 102b. A restraining portion 106 of the cord 104 may be defined between the clamps 102a, 102b.

Referring to FIG. 3 and FIG. 4, first apertures 308a, 308d may be disposed laterally through the first terminals 304a, 304c of the clamps 102a, 102b, respectively. Preferably, the first apertures 308a, 308d are disposed at a lower end of the respective first terminals 304a, 304c.

The apertures 308a-f may each receive a portion of the cord 104. Through the first clamp 102a, the cord 104 may extend through the first aperture 308a and third aperture 308c in a first direction and may extend through the second aperture 308b in a second, e.g., opposite, direction. Through the second clamp 102b, the cord 104 may extend through the first aperture 308d and third aperture 308f in a first direction and may extend through the second aperture 308e in a second, e.g., opposite, direction.

Referring to FIG. 17 and FIG. 18, apertures 308a-h may be disposed laterally through the first terminals 304a, 304c of the clamps 102a, 102b, respectively. Preferably, the first apertures 308a, 308e are disposed at a lower end of the respective first terminals 304a, 304c.

The apertures 308a-h may each receive a portion of the cord 104. Through the first clamp 102a, the cord 104 may extend through the aperture 308a in a first direction and may extend through the second aperture 308b in a second, e.g., opposite, direction. Through the second clamp 102b, the cord 104 may extend through the aperture 308e in a first direction and may extend through the second aperture 308f in a second, e.g., opposite, direction.

Referring to FIGS. 1-4, 6, 9, 11, 14-18, 20, 25, and 28, clamps 102a, 102b may remain coupled to a cord 104 because the outer surface of the cord 104 may be abutted against inner surfaces of the clamps 102a, 102b. Moreover, the outer surface of the cord 104 may be in physical contact with the inner surfaces of the clamps 102a, 102b. The inner surfaces may define apertures 308 in the clamps 102a, 102b. Accordingly, friction between the cord 104 and the inner surfaces of the clamps 102a, 102b would inhibit each clamp 102 from sliding relative to the cord 104.

However, a percussionist may pull on the cord 104 to slide one or more portions of the cord 104 across the inner surfaces of a clamp 102. Pulling on the cord 104 may cause one or more portions of the cord 104 adjacent the inner surfaces of the clamp 102 to be stretched, e.g., elongated. When stretched, the one or more portions of the cord 104 would deform to have a smaller diameter. Friction would be reduced between the stretched one or more portions of the cord 104 and the adjacent inner surfaces. Thus, the one or more portions of the cord 104 may be slid through the clamp 102.

Referring to FIGS. 1-28, a percussionist may couple clamps 102a, 102b and a cord 104 to a drum hoop 202 of a drum 200 as follows. First, the percussionist may couple a first clamp 102a to a first portion of the drum hoop 202. The percussionist may turn a thumb screw 306a clockwise to cause the thumb screw 306a to be extending through a second terminal 304b of the first clamp 102a. The thumb screw 306a may be turned clockwise until it is abutted against an outer surface of the drum hoop 202 and a terminal 304a of the clamp 102a is abutted against an inner surface of the first portion of the drum hoop 202.

Next, the percussionist may pull a second clamp 102b towards a second portion of the drum hoop 202. The percussionist may couple the second clamp 102b to the second portion of the drum hoop 202. The percussionist may turn a thumb screw 306b clockwise to cause the thumb screw 306b to be extending through a second terminal 304d of the second clamp 102b. The thumb screw 306b may be turned clockwise until it is abutted against an outer surface of the drum hoop 202 and a terminal 304c of the clamp 102b is abutted against an inner surface of the second portion of the drum hoop 202.

A restraining portion 106 of a cord 104 may be extending from the first portion of the drum hoop 202 to a second portion of the drum hoop 202. Accordingly, the restraining portion 106 may be stretched between the first portion and a second portion of the drum hoop 202. The restraining portion 106 may also be stretched across a drumhead 204 of the drum 200. Additionally, the restraining portion 106 may be parallel to the drumhead 204.

Afterwards, the percussionist may couple a percussive effects object (not shown) to the restraining portion 106 of the cord 104 and the drumhead 204 in various configurations. In a first configuration, the percussionist may hang, e.g., with a hook or a clip, a percussive effects object onto the restraining portion 106. A portion of the percussive effects object may be in physical contact with, e.g., abutted against, the drumhead 204.

In a second configuration, the percussionist may prefer to rest the percussive effects object against the drumhead 204 and the restraining portion 106 of a cord 104. Essentially, the restraining portion 106 may provide a barrier that inhibits the percussive effects object from being moved past the cord 104. Accordingly, in some cases, if the drumhead 204 were positioned parallel to the ground and vibration were imparted to the drumhead 204, the vibration would cause the percussive effects object to move relative to the drumhead 204. However, the cord 104 would inhibit movement of the percussive effects object in the direction of the cord 104. In other cases, if the drumhead 204 were positioned at a tilt, e.g., angle, relative to the ground, the cord 104 would inhibit the percussive effects object from being slid past the cord 104, down the drumhead 204.

In a third configuration, the percussionist may position the percussive effects object between the drumhead 204 and the restraining portion 106. First, the percussionist may pull the restraining portion 106 away from the drumhead 204. Moreover, the restraining portion 106 may be pulled orthogonally to the drumhead 204. Pulling on the restraining portion 106 may stretch, e.g., elongate, and/or increase tension on the restraining portion 106. Next, the percussionist may set the percussive effects object between the drumhead 204 and the restraining portion 106. Then, the percussionist may release the restraining portion 106. An upper surface of the percussive effects object may now be abutted against the restraining portion 106. Also, a lower surface of the percussive effects object may be abutted against the drumhead 204. Accordingly, friction between the drumhead 204, the percussive effects object, and the restraining portion 106 may inhibit movement of the percussive effects object relative to the drumhead 204 and/or the restraining portion 106.

In some cases, an unstretched restraining portion 106 of a cord 104 may be longer than the shortest distance, e.g., line or geometric chord, from a first portion of the drum hoop 202 to a second portion of the drum hoop 202. Two clamps 102a, 102b may be respectively coupled to the first portion and the second portion of the drum hoop 202. In such cases, a percussive effects object may not be retained on and/or between the restraining portion 106 and a drumhead 204. The percussionist may want to shorten the unstretched restraining portion 106. First, the percussionist may pull a first end of the cord 104 through one or more apertures 308 (FIGS. 1-4 and 15-19) disposed through the clamp 102a. Then, the percussionist may slide a first clamp 102a towards the midpoint of the cord 104. The length of the unstretched restraining portion 106 may now be shorter. The now shorter restraining portion 106 may be stretched such that tension exists on the restraining portion 106.

In other cases, a stretched restraining portion 106 of a cord 104 may be shorter than the shortest distance from a first portion of the drum hoop 202 to a second portion of the drum hoop 202. In such cases, to couple the cord 104 to the first portion and the second portion of the drum hoop 202, the percussionist may increase the length and/or tension of the restraining portion 106. First, the percussionist may pull on the restraining portion 106 to cause an end portion of the cord 104 to be slid through apertures 308 (FIGS. 1-4 and 15-19) disposed in a first clamp 102a. At the same time, the first clamp 102a may be slid away from the midpoint of the cord 104. Thus, the length of the unstretched restraining portion 106 may now be longer.

The percussionist may then release the restraining portion of the cord 104. Accordingly, the outer surface of the cord 104 would be abutted against one or more inner surfaces of the first clamp 102a. Thus, the first clamp 102a would remain coupled to the cord 104.

The percussionist may further increase the length and/or tension of the restraining portion 106 by performing the same steps above in relation to a second clamp 102b, and one or more apertures 308 disposed in the second clamp 102b.

Next, the percussionist may couple the two clamps 102a, 102b to the first portion and the second portion of the drum hoop 202.

In alternate cases, to prevent the cord from being accidently pulled out of a clamp 102, the percussionist may optionally tie a knot 310 on one or both ends of the cord 104. In other cases, the percussionist may optionally couple a cord lock (not shown) on one or both ends of the cord 104. When the cord 104 is pulled, the knot 310 or the cord lock would be abutted against a clamp 102. Thus, the knot 310 or the cord lock would inhibit ingress or egress of the cord 104 through the clamp 102.

Other alternative versions of drum coupling assemblies may be described in reference to FIGS. 15-28. There are two drawing pages for each of two other designs represented in the drawings attached for the Strap/Cord Attachment and Spanning Devices (four drawing pages total). A strap/cord attachment and spanning devices may also be referred to as “a drum coupling assembly.” Each of the two designs function the same way but have different dimensions to accommodate use on either a drum rim, or drum hoop. FIGS. 15, 16, 19, 20, 21, 22 and 23 correspond to the Strap/Cord Attachment and Spanning Devices for a standard size drum rim. FIGS. 17, 18, 24, 25, 26, 27, and 28, correspond to the Strap/Cord Attachment and Spanning Devices for a standard size drum hoop. Because the two designs function the same way, many of the figures demonstrate the same principals and details and can be interchangeable. The figure sets that demonstrate the same principals and details are: FIGS. 15 & 17, FIGS. 16 & 18, FIGS. 19 & 24, FIGS. 20 & 25, FIGS. 21 & 26, FIGS. 22 & 27, FIGS. 23 & 28.

FIGS. 15, 16, 17 and 18 shows angled views of the complete Strap/Cord Attachment and Spanning System assembly, which includes: 2× Strap/Cord Attachment and Spanning Devices, and 1× cord/strap. They also show that one Strap/Cord Attachment and Spanning Devices consists of, 1× Mount Body, and 1× Thumb Screw.

FIG. 19 and FIG. 24 show isometric views of the Strap/Cord Attachment and Spanning System installed on a drum.

FIG. 20 and FIG. 25 show detail views from FIG. 19 and FIG. 24 respectively. The views are close-ups of the Strap/Cord Attachment and Spanning Device installed on a drum rim and hoop.

FIG. 21 and FIG. 26 show section views of FIG. 22 and FIG. 27, for the purpose of providing a clear side view of the Strap/Cord Attachment and Spanning Devices on a drum rim and hoop.

FIG. 22 and FIG. 27 show plan views of the Strap/Cord Attachment and Spanning System installed on a drum.

FIG. 23 and FIG. 28 show detail views from FIG. 21 and FIG. 26 respectively. The views are close-ups of the sides of the Strap/Cord Attachment and Spanning Devices installed on a drum rim and hoop.

Other versions of drum coupling assemblies may be described in reference to FIG. 23 and FIG. 28, which show the general U-shape of the Mount Body on the Strap/Cord Attachment and Spanning Device. The dimensions for the Strap/Cord Attachment and Spanning Device shown in FIG. 23, are the appropriate sizes for a standard drum rim to fit inside the U-shape, and the dimensions for the Strap/Cord Attachment and Spanning Device shown in FIG. 28, are the appropriate sizes for a standard drum hoop to fit inside the U-shape. This geometry allows the Strap/Cord Attachment and Spanning Device to be attached to a drum rim or hoop by means of clamping the Mount Body against the drum rim or hoop using a thumb screw threaded into the back portion of the Mount Body with the tightening head of the thumb screws on the outside of the drum rim or hoop away from the drumhead. This clamping process can be easily loosened and tightened for simple and quick location and height adjustments of the Strap/Cord Attachment and Spanning Devices on the drum rim or hoop. This clamping mechanism does not need to be the mechanism for attaching the Strap/Cord Attachment and Spanning Device to a drum rim or hoop. A spring clamp, flexible clamp or other attachment system could also be used.

FIGS. 19, 22, 24 and 27, show how 2x Strap/Cord Attachment and Spanning Devices clamp onto two separate locations of a drum rim or hoop, and how each of the two ends of a strap/cord, with some elasticity, are attached to one of the two Strap/Cord Attachment and Spanning Devices by lacing them through the holes on the Mount Body, allowing the strap/cord to span between them and across the surface of a drumhead. Changing the span of the strap/cord between the two Strap/Cord Attachment and Spanning Devices allows for different sized objects to be held or corralled in different locations on the drumhead surface by the strap/cord.

Additionally, FIGS. 19, 20, 22, 24, 25 and 27, show how the strap/cord ends loop around the outside of the Strap/Cord Attachment and Spanning Devices and lace through holes on the Mount Bodies allowing tension adjustment by feeding slack on the strap/cord in and out of the holes on the Mount Bodies. Lacing the strap/cord to the Strap/Cord Attachment and Spanning Device does not need to be the mechanism for attaching and adjusting the strap/cord to the Strap/Cord Attachment and Spanning Device. Other methods of attachment and adjustment can be used.

FIGS. 19, 20, 22, 24, 25 and 27 illustrate use in the Strap/Cord Attachment and Spanning System with their respective details and notes, demonstrate how the elasticity in the strap/cord allow it to be held tight against and between the Strap/Cord Attachment and Spanning Device's Mount Bodies when no slack is present.

As shown in FIGS. 19, 22, 24 and 27, a combination of the strap/cord wrapping around the outside of the Mount Bodies in tension, and the friction caused by this, the hole sizes and hole locations on the Mount Bodies, prevent the strap/cord from loosening during drum vibrations and playing operations, and allow for the strap/cord to be tensioned as desired.

The construction details of the various disclosed drum coupling assemblies are that the separate components be made of plastic, metal or any other material that is sufficiently rigid and strong enough to withstand all the required clamping pressures, drum vibrations and impacts from other objects. Furthermore, it should be made from a material that will not damage a drum rim or hoop.

The advantages of the disclosed drum coupling assemblies include a simple device which allows for simple placement, security and control of various objects placed against a drumhead surface at any angle, there is a wide range of objects and materials that can be used, changes of the location and pressure of the objects placed on a drumhead is quick and simple allowing for experimentation and customization, it is small and can be transported very easily and is minimally invasive when attached to a drum rim or hoop, the drum coupling assemblies do not damage drumheads as adhesives would, and the drum coupling assemblies can suspend the strap/cord above the drumhead so the strap/cord does not disrupt the natural vibrations and resonance of the drum when it is not holding an object in place.

The disclosed drum coupling assemblies allow a strap/cord to be attached to a drum rim or hoop and be spanned across the surface of the drumhead.

The disclosed drum coupling assemblies prevent objects from falling off a drumhead due to contact with the object during playing and/or drum vibrations.

The disclosed drum coupling assemblies prevent undesired movement of an object placed against a drumhead.

The disclosed drum coupling assemblies allow for control of an object's location on a drumhead through the placement and position of the Strap/Cord Attachment and Spanning Devices.

The disclosed drum coupling assemblies allow for pressure control of an object against a drumhead through the tightening or loosening of the strap/cord from the Strap/Cord Attachment and Spanning Devices.

While the foregoing written description of the disclosed drum coupling assemblies enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations and equivalents of the specified embodiment, method and examples herein. The inventions should therefore not be limited by the above described embodiment, method and examples, but by all embodiments and methods within the scope and spirit of the inventions as claimed.
