The present invention relates to percussion instruments, and particularly to a system for inserting and retracting percussion instruments.
Percussion sets have been developed that produce a large variety of different sounds. Percussion sets may include, for example, drums, cymbals, bells, cowbells, hi-hats, tambourines, wood blocks, etc. Even among drums a large variety of different drums exists such as, for example, kettle drums, steel drums, bongo drums, tom-toms, bass drums, tenor drums, snare drums, etc. To add to the abundance of sounds produced by these different percussion instruments, different techniques (e.g., rim shots, etc.) for striking or beating these percussion instruments have been developed to obtain different sounds from any one instrument.
Conventionally, however, percussion instruments were located relative to the player (i.e., the percussionist) at fixed positions. Since the instruments take space, there was a limit in the number of instruments that may form part of any one percussion set. Moreover, the fixed locations of each of the instruments limited the number of sounds that the percussion set could produce.
The invention disclosed herein provides a system for inserting and retracting percussion instruments from a percussion set. Using the systems disclosed herein players are able to produce broader ranges of sounds and rhythms because different arrangements of percussion instruments may be available to the percussionist as the percussionist is playing that otherwise would not be available.
Moreover, an arrangement may be set where, for example, drum beats occur from striking a first drum downwardly and a second drum, that has been inserted above the first drum by use of the systems disclosed herein, upwardly. This way, the percussionist may double the amount of resulting drum beats; i.e., the conventional beats from the downward strikes plus the beats that result from the upward strikes.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate various example systems, methods, and so on, that illustrate various example embodiments of aspects of the invention. It will be appreciated that the illustrated element boundaries (e.g., boxes, groups of boxes, or other shapes) in the figures represent one example of the boundaries. One of ordinary skill in the art will appreciate that one element may be designed as multiple elements or that multiple elements may be designed as one element. An element shown as an internal component of another element may be implemented as an external component and vice versa. Furthermore, elements may not be drawn to scale.
The insertable percussion system 1 also includes an inserting/retracting mechanism 7 connected to the percussion instrument 3 and the stand 5. The system 1 also includes a pedal 9 disposed on the floor F at or near the base 5a of the stand 5. The stand 5 vertically separates the percussion instrument 3 and the inserting/retracting mechanism 7 from the pedal 9. The insertable percussion system 1 also includes a cable 11 that connects the pedal 9 to the inserting/retracting mechanism 7. Operation (i.e., pressing and releasing) of the pedal 9 up or down causes the pedal 9 to pull and release on the cable 11 which, in turn, causes the inserting/retracting mechanism 7 to move the percussion instrument 3 substantially horizontally.
Pressing down on the pedal 9 causes the pedal 9 to pull on the cable 11 which, in turn, causes the inserting/retracting mechanism 7 to move the percussion instrument 3 substantially horizontally from a retracted position as shown in
In one embodiment, the insertable percussion system 1 as shown in
In one embodiment, the insertable percussion system 1 as shown in
In another embodiment, the roles are reversed; i.e., the percussion instrument 3 may be intended to be played by being hit with a downstroke or downward motion of the beater or the drum stick and the percussion instrument 3 is inserted under or below an upstroke percussion instrument.
The percussionist may strike the downstroke percussion instrument 103 in the downstroke motion and the upstroke percussion instrument in the proceeding (i.e., immediately after) upstroke motion. This way, the percussionist may double the amount of resulting drum beats; i.e., the conventional beats from the downward strikes plus the beats that result from the upward strikes of the percussion instrument 3. Whenever the percussionist is ready to conclude playing in this upstroke/downstroke mode, the percussionist may remove or retract the percussion instrument 3 by operation of the pedal 9.
In the upstroke/downstroke embodiment above, the inserted position of the insertable percussion system 1 may correspond to a position where a majority of a playing surface of the upstroke drum (e.g., the skin of the percussion instrument 3) faces or vertically overlaps a majority of a playing surface of the downstroke drum 103. The retracted position of the insertable percussion system 1, on the other hand, may correspond to a position where the majority of the playing surface of the upstroke drum (e.g., the skin of the percussion instrument 3) does not face or does not vertically overlap the majority of the playing surface of the downstroke drum 103. In the illustrated embodiment, the inserting/retracting mechanism 7 includes a first arm 13 and a second arm 15.
Pulling of the cable 11 by operation of the pedal 9 causes the second arm 15 to rotate about the stand end 15a and the joint end 15b, and the first arm 13 to rotate about the joint end 13b and the percussion instrument end 13a to effectively stretch the inserting/retracting mechanism 7 causing the percussion instrument 3 to move horizontally away from the stand 5 to the inserted position.
Releasing of the cable 11 by operation of the pedal 9 causes the second arm 15 to, in opposite direction as in the inserting, rotate about the stand end 15a and the joint end 15b, and the first arm 13 to rotate about the joint end 13b and the percussion instrument end 13a to effectively contract the inserting/retracting mechanism 7 causing the percussion instrument 3 to move horizontally towards the stand 5 to the retracted position.
In the illustrated embodiment of
In one embodiment (not shown), the inserting/retracting mechanism 7 includes a spring configured in the inserting/retracting mechanism 7 to bias the inserting/retracting mechanism 7 towards retraction (i.e., in the retracted position). In this embodiment, pulling of the cable 11 by operation of the pedal 9 defeats tension force in the spring extending the spring and causing the second arm 15 to rotate about the stand end 15a and the joint end 15b, and the first arm 13 to rotate about the joint end 13b and the percussion instrument end 13a to effectively stretch the inserting/retracting mechanism 7 causing the percussion instrument 3 to move horizontally away from the stand 5 to the inserted position. Releasing of the cable 11 by operation of the pedal 9 allows tension force in the extended spring to retract the inserting/retracting mechanism 7 into the retracted position such that the percussion instrument 3 is moved horizontally towards the stand 5.
Pressing of the foot or shoe of the person playing the insertable percussion system 1 causes the foot platform 17 to rotate about the rotating location 19a. This rotation pulls on the cable 29 which causes the rod 23 and the cable wheel 25 to also rotate effectively pulling on the cable 11 and stretching the inserting/retracting mechanism 7 into the inserted position.
Releasing of the foot or shoe of the person playing the insertable percussion system 1 causes the foot platform 17 to rotate, in the opposite direction as insertion, about the rotating location 19a. This opposite rotation releases the cable 29 which causes the rod 23 and the cable wheel 25 to also rotate effectively releasing on the cable 11 and retracting the inserting/retracting mechanism 7 into the retracted position.
When the player or percussionist desires to retract the percussion instrument 3 to the retracted position, the player or percussionist may move the foot platform 17 laterally or sideways in the opposite direction as engagement to disengage the latching tab 31 from the latching bracket 33. The player or percussionist may then release his foot or shoe from the foot platform 17 to retract the inserting/retracting mechanism 7 into the retracted position.
The first arm 13 includes a percussion instrument end 13a that operably and rotably connects to the percussion instrument 3. In the illustrated embodiment, the exemplary insertable percussion system 1 includes a slide bracket 35 that operably and rotably connects the percussion instrument end 13a to the percussion instrument 3. The first arm 13 also includes a joint end 13b that is distal the percussion instrument 3. The joint end 13b operably and rotably connects to the second arm 15.
The second arm 15 includes a stand end 15a that operably and rotably connects to the stand 5. In the illustrated embodiment, the exemplary insertable percussion system 1 includes a slide bracket 37 that operably and rotably connects the stand end 15a to the stand 5. The stand end 15a of the second arm 15 may be connected to the cable 11. The second arm 15 also includes a joint end 15b that is distal to the stand 5 and that operably and rotably connects to the joint end 13b of the first arm 13.
In the illustrated embodiment of
Pulling of the cable 11 by operation of the pedal 9 causes the second arm 15 to rotate about the stand end 15a, the joint end 15b, and the joint position 15c. This causes the first arm 13 to rotate about the joint end 13b, about the percussion instrument end 13a, and about the joint position 13c to effectively stretch the inserting/retracting mechanism 7 causing the percussion instrument 3 to move horizontally away from the stand 5 to the inserted position.
Releasing of the cable 11 by operation of the pedal 9 causes the second arm 15 to, in opposite direction as in the inserting, rotate about the stand end 15a, the joint end 15b, and the joint position 15c. This causes the first arm 13 to rotate about the joint end 13b, the percussion instrument end 13a, and the joint position 13c to effectively contract the inserting/retracting mechanism 7 causing the percussion instrument 3 to move horizontally towards the stand 5 to the retracted position.
In one embodiment (not shown), the inserting/retracting mechanism 7 includes a spring configured in the inserting/retracting mechanism 7 to bias the inserting/retracting mechanism 7 towards retraction (i.e., in the retracted position). In this embodiment, pulling of the cable 11 by operation of the pedal 9 defeats tension force in the spring extending the spring and causing the second arm 15 to rotate about the stand end 15a, the joint end 15b, and the joint position 15c. This causes the first arm 13 to rotate about the joint end 13b, the percussion instrument end 13a, and the joint position 13c to effectively stretch the inserting/retracting mechanism 7 causing the percussion instrument 3 to move horizontally away from the stand 5 to the inserted position. Releasing of the cable 11 by operation of the pedal 9 allows tension force in the extended spring to retract the inserting/retracting mechanism 7 into the retracted position such that the percussion instrument 3 is moved horizontally towards the stand 5.
The inserting/retracting mechanism 105 may include a base 110, a first arm 121 and a second arm 123. The base 110 operably couples the first arm 121 and the second arm 123 to the stand 113. The first and second arms 121 and 123 have percussion instrument ends 121a and 123a, proximate the percussion instrument 3 and free end 121b and 123b distal the percussion instrument 3. The percussion instrument ends 121a and 123a may be coupled to a holding element 115, e.g., a U-shaped metal or plastic rod, which attaches to the side surface of the percussion instrument 3. The holding element 115 couples the percussion instrument 3 to the inserting/retracting mechanism 105. The first and second arms 121 and 123 may slide through the bushing elements 117a-d of the base 110 in the directions shown by the arrow A.
The inserting/retracting mechanism 105 may include an input device 125, a motor 127, a gear mechanism 131, and a feedback mechanism 133.
The input device 125 may include one or more switching elements (e.g., touch pads) 125a and 125b, for receiving an operation instruction and generating an operation signal to activate the inserting/retracting mechanism 105. For example, a hit (using a beater or drum stick) on switching element 125a may correspond to an instruction to insert the percussion instrument 3 while a hit (using a beater or drum stick) on switching element 125b may correspond to an instruction to retract the percussion instrument 3. In another example, a first hit (using a beater or drum stick) on switching element 125a may correspond to an instruction to insert the percussion instrument 3 while a second hit (using a beater or drum stick) on switching element 125a may correspond to an instruction to retract the percussion instrument 3. In yet another example, the input device may be disposed near the floor F such that it may receive an operation instruction in the form of a user/player pressing the one or more switching elements with her foot.
The inserting/retracting mechanism 105 may also include a controller 137. The controller 137 may receive the operation signal from the input device 125 and determine the current position of the percussion instrument 3 by use of the feedback mechanism 133.
The feedback mechanism 133 may include Hall-effect sensors 133a and 133b disposed on the base 110 and a permanent magnet 133c disposed on the first arm 121. The feedback mechanism 133 determines the position of the first arm 121 along its travel relative to the base 110 and, thus, the position of the percussion instrument 3. For example, when the permanent magnet 133c is aligned with the Hall sensor 133b, the percussion instrument 3 may be at or in proximity, e.g., 5-10 cm, to the retracted position. See
The controller 137 may be a microcontroller PIC 12F683 manufactured by Microchip Technology Inc. of Independence, Ohio. However, the controller 137 may include any type of controller sufficient for receiving and generating the above-described signals. The Hall-effect sensors 133a and 133b may be micro-power ultra-sensitive Hall-effect switches manufactured by Allegro MicroSystems, LLC of Worcester, Mass. However, the Hall-effect sensors 133a and 133b may be any other type of Hall-effective sensors sufficient for detecting the permanent magnet 131c and generating the above-described signals. Indeed, the feedback mechanism 133 may include any other type of sensors suitable for detecting relevant position information.
The stand 113 supports and sustains the percussion instrument 3 and the inserting/retracting mechanism 105 vertically off the floor F. The stand 113 may include a fixing element 113a that couples to the inserting/retracting mechanism 105. The stand 113 may also include a joint 113b, a base 113c, and a latch 113d. The joint 113b may allow for the inserting/retracting mechanism 105 and the percussion instrument 3 to be adjusted and set at an angle different from horizontal and for collapsing the system 100 for storage. See
The gear mechanism 131 may include a rack 131a and a pinion 131b. A shaft (not shown) of the motor 127 may be operably coupled to the pinion 131b of the gear mechanism 131 so as to actuate the pinion 131b to turn in a direction to cause a linear actuation of the rack 131a in the directions shown by the arrow A. The motor 127 receives the command signal and actuates the gear mechanism 131. The rack 131a is fixedly coupled to the first arm 121 (or the second arm 123) of the inserting/retracting mechanism 105 so that the first arm 121 may slide through the bushings 117b and 117c as the rack 131a pushes or pulls the percussion instrument 3. The second arm 123 moves in unison with the first arm 121.
The insertable percussion systems disclosed above accomplish the goals of increasing the availability and variety of percussion sounds that may be played. However, their horizontal insertion design may be inherently unstable because of the significant change in weight distribution between the retracted position and the inserted position, and the momentum generated by the transition. Moreover, when used to insert or retract a heavy percussion instrument, a significant amount of force may be necessary to accomplish the transition between inserted and retracted. The inventor, thus, set out to design an embodiment of the invention that is immune to these issues.
The percussion instrument 3 may be mounted to a holding element 215 which is operably coupled to a counter-weight cradle 226. The percussion instrument 3, the holding element 215, and the counter-weight cradle 226 form a pendulum assembly pivotably coupled to a fulcrum assembly 204. The fulcrum assembly 204 may be coupled to the stand 13 to be supported off the floor F. The percussion instrument 3, the holding element 215, and the counter-weight cradle 226 may form the pendulum assembly and pivot smoothly relative to the fulcrum assembly 204. This way, the percussion instrument may be moved or inserted vertically and horizontally along the arch β from the retracted/vertical position of
The counter-weight cradle 226 may accommodate many different counter-weights of different weights.
The mechanism 205 may include a pivot rod 210 (visible in
In one embodiment, the mechanism 205 may include a motor 214 operably coupled to the pivot rod 210 so that the motor 214 may pivot the pendulum assembly (i.e., the percussion instrument 3, the holding element 215, and the counter-weight cradle 226) about the fulcrum axis α relative to the fulcrum element 204. For example, a shaft of the motor 214 may be coupled to the pivot rod 210 to pivot the pendulum assembly along the arch β from the retracted/vertical position of
The mechanism 205 may further include input devices configured to receive operation instructions corresponding to moving the percussion instrument 3 from the retracted position to the inserted position or from the inserted position to the retracted position, and to generate an operation signal based on the operation instructions. The mechanism 205 may also include a controller operably coupled to the motor 214 and the input device to actuate the motor 214 based on the operation signal.
In one embodiment, the input device includes a touch pad 216 configured to receive operation instructions in the form of hits from a drum stick. A first hit of the drum stick may correspond to a first operation instruction to move the percussion instrument 3 from the retracted position to the inserted position. A subsequent hit of the drum stick may correspond to a second operation instruction to move the percussion instrument 3 from the inserted position to the retracted position.
In the illustrated embodiment, the input device includes first and second touch pads 216, 218 configured to receive operation instructions in the form of hits from a drum stick. A hit of the first touch pad 216 may correspond to a first operation instruction to move the percussion instrument 3 from the retracted position to the inserted position. A hit of the second touch pad 218 may correspond to a second operation instruction to move the percussion instrument 3 from the inserted position to the retracted position.
In another embodiment, the input device includes a foot pedal (not shown) configured to receive the operation instructions in the form of pressings from a foot of a user or player. A first pressing may correspond to a first operation instruction to move the percussion instrument 3 from the retracted position to the inserted position. A subsequent pressing may correspond to a second operation instruction to move the percussion instrument 3 from the inserted position to the retracted position.
The mechanism 205 may further include a setting control or setting knob 220 operably coupled to the motor 214 or the pivot rod 210, and configured to set a pivot angle of the pendulum assembly about the fulcrum axis α relative to the fulcrum element 204. By operating the setting control 20 a user may control the travel distance (angle) of the percussion instrument 3 to the desired angle setting.
The mechanism 205 may further include a removable battery pack 222 that powers the motor 214 and electronic circuit without the need for plugging into a wall socket for power.
The holding element 215 may be operably coupled to the counter-weight cradle 226 by, for example, a pivot rod 224. The pivot rod 224 may allow the percussion instrument 3 to swivel relative to the holding element 215.
In the percussion set, the percussion instrument 3 may be inserted by operation of the motor 214 as described above to make the percussion instrument 3 temporarily available to the percussionist to play. The percussion instrument 3, for example, may be inserted above a second percussion instrument in the percussion set to make the percussion instrument 3 available to the percussionist in addition to the second percussion instrument. The inserted position corresponds to a position where a majority of a playing surface of the first percussion instrument 3 faces or vertically overlaps a majority of a playing surface of the second percussion instrument. Such a percussion set reduces the playing space, increases variety in sounds played, and thus, increases the enjoyment of play and or listening to performance of the percussion set. As another example, the second percussion instrument may be replaced with another type of instrument. Whenever the percussionist selects to play the other instrument alone, the percussionist may remove or retract the percussion instrument 3 by operation of the motor 224 to make the other instrument available for the percussionist to play.
The term “percussion instrument” as used herein refers to musical instruments in which sound is generally obtained by striking the instrument with hands, beaters, sticks, etc. and their electronic equivalents. Examples of percussion instruments include drums, cymbals, bells, cowbells, hi-hats, tambourines, wood blocks, kettle drums, steel drums, bongo drums, tom-toms, bass drums, tenor drums, snare drums, etc. The term “drum” as used herein corresponds to any type of percussion musical instrument having at least one stretched membrane to generate sound by acoustic vibration when the stretched membrane is struck or their electronic equivalent (e.g., electronic drum pad.)
While example systems, methods, and so on, have been illustrated by describing examples, and while the examples have been described in considerable detail, it is not the intention to restrict or in any way limit the scope of the appended claims to such detail. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the systems, methods, and so on, described herein. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the invention is not limited to the specific details, and illustrative examples shown or described. Thus, this application is intended to embrace alterations, modifications, and variations that fall within the scope of the appended claims. Furthermore, the preceding description is not meant to limit the scope of the invention. Rather, the scope of the invention is to be determined by the appended claims and their equivalents.
To the extent that the terms “in” or “into” are used in the specification or the claims, it is intended to additionally mean “on” or “onto.” Furthermore, to the extent the term “connect” is used in the specification or claims, it is intended to mean not only “directly connected to,” but also “indirectly connected to” such as connected through another component or components. An “operable connection,” or a connection by which entities are “operably connected,” is one by which the operably connected entities or the operable connection perform its intended purpose. For example, two entities may be operably connected to each other directly or through one or more intermediate entities.
To the extent that the term “includes” or “including” is employed in the detailed description or the claims, it is intended to be inclusive in a manner similar to the term “comprising” as that term is interpreted when employed as a transitional word in a claim. Furthermore, to the extent that the term “or” is employed in the detailed description or claims (e.g., A or B) it is intended to mean “A or B or both”. When the applicants intend to indicate “only A or B but not both” then the term “only A or B but not both” will be employed. Thus, use of the term “or” herein is the inclusive, and not the exclusive use. See, Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (3D. Ed. 1995).
