The present invention relates to a curved pedal and to a device employing a curved pedal; in particular, the present invention relates to a curved pedal for a drum or other foot-operated device where dexterity, responsiveness, and/or comfort when operating for an extended period of time are desired.
Many devices employ pedals for foot-actuated operation. Among the many devices capable of foot-actuated operation by way of pedal(s) are automobiles, helicopters, airplanes, backhoes and other such vehicles and heavy equipment, looms, sewing machines, treadles, knitting machines, mills, lathes, pumps, and other such industrial apparatuses, to name just a few examples.
Another category of device which may employ pedal(s) for foot-actuated operation is musical instruments such as organs, pianos, and other keyboard instruments, as well as drums, cymbals, and other such percussion instruments.
Drum pedals have been used for playing drums for more than a century. Many improvements on the drum pedal have been made, allowing better operability and facilitating various performance styles.
One factor still in need of improvement with pedals currently on the market is comfort. Repeated multiple beats, e.g., doublets, triplets, etc., provide an attractive performance but can be difficult and tiring for many players. Many players find that their foot becomes fatigued after performing for an extended period of time, especially when generating repeated multiple beats in rapid succession.
Another factor still in need of improvement with pedals currently on the market is ability to accommodate various techniques.
To generate a doublet, i.e., two repeated beats, a player might simply repeat the same foot movement twice in rapid succession, or for improved comfort and greater degrees of freedom during playing a player might, for example, employ a sliding technique or a heel-toe technique.
In a sliding technique for producing a doublet, a player might first depress one location of the drum pedal with his or her toe to generate a first stroke, slide the foot along the pedal toward the toe or the heel end of the pedal, and then depress a second location of the pedal to generate a second stroke. However, with a conventional flat pedal, many players find foot positioning difficult and find the sliding motion difficult to control or uncomfortable.
In a heel-toe technique for producing a doublet, a player might first depress the pedal with his or her heel to generate a first stroke, and then tilt the toe down to depress the pedal with his or her toe to generate a second stroke. This technique can cause fatigue of the ankle when playing for an extended period.
Similar techniques may also be employed for producing a triplet, i.e., three repeated beats, which is generally even more difficult than a doublet.
Conventional pedals are typically flat, or where such conventional deviate from planar, they may have spiky protrusions, and may employ joggled or stepped surfaces.
With a flat drum pedal, techniques such as the sliding technique and the heel-toe technique are tiring and are difficult to master. A flat pedal is generally devoid of features that might assist the player in locating the foot during playing. Unless a player can quickly and reliably locate his or her foot by the “feel” of the pedal, it will be difficult to develop the dexterity required for advanced sliding and heel-toe techniques.
Furthermore, a flat pedal is a poor match for the shape of the foot, and a flat pedal requires considerably more movement of the foot and/or ankle than would be necessary if the pedal were a better match for the shape of the foot.
Moreover, when using the heel-toe technique with a flat pedal, the heel and/or toe tend to strike the pedal surface at a glancing angle. A pedal shape that would permit the foot—and in particular the heel of the foot and/or the ball of the foot (note that the term “toe” as used herein may include the ball of the foot)—to strike the pedal at an angle more nearly perpendicular to the pedal surface would improve the leverage or efficiency with which force is transferred from the player's foot to the drum pedal, permitting stronger and/or less tiring performance.
Furthermore, a pedal surface that is interrupted by spiky protrusions or sharply stepped surfaces is not conducive to techniques that utilize sliding motion of the foot across the pedal surface. Moreover, a pedal having a smoothly varying contour would be especially desirable for a player who employs bare feet or who wears socks but no shoes or who wears thin shoes or other such foot coverings for improved comfort and sensitivity in locating the foot on a pedal.
In addition, whereas conventional pedals tend to be only slightly longer than the foot of the player, a pedal that is substantially longer than the foot of the player would not only increase leverage about the fulcrum of the heel hinge, permitting more powerful and/or less tiring playing, but would also facilitate more sustained sliding along the length direction of the pedal. A pedal substantially longer than the foot of the player may also accommodate multiple striking locations beyond the basic heel-toe striking positions employed conventionally.
There is therefore a need for an improved pedal that addresses at least one of the foregoing issues.
One aspect of the present invention is a curved pedal. Another aspect of the present invention is a pedal assembly or other device employing such a curved pedal. One embodiment of the present invention is a curved pedal for a drum or other foot-operated device where dexterity, responsiveness, and/or comfort when operating for an extended period of time are desired.

Where at least one first convexity, at least one first concavity, and at least one second convexity are present, the at least one first concavity may be disposed centrally in the length direction between the at least one first convexity and the at least one second convexity.
The at least one first convexity and/or the at least one second convexity might be substantially a half-lobe that extends or extend not more than 25% peripherally past an extremum or extrema thereof.

Having identified one end of curved pedal 130 as the heel end thereof, and having identified the other end of curved pedal 130 as the toe end thereof, these directions, i.e., the heel end or side which is toward the left as seen in
Pivoting linkage arms 122 are oriented more or less vertically, the bottom ends of pivoting linkage arms 122 being connected to either side of the toe end of curved pedal 130, toe end of curved pedal 130 having hole(s) and/or other features permitting connection to the bottom ends of pivoting linkage arms 122, and the top ends of pivoting linkage arms 122 being connected to either side of the toe end of a rocker 120 on which beater stem 118 terminating in beater 115 is mounted. As the toe end of curved pedal 130 swings through its arc about the pivot of heel hinge 114, transfer of this rotary motion to rocker 120 via pivoting linkage arms 122 causes rocker 120 to pivot about rocker axle 116 which is supported by bearings held by support posts 124 secured to baseboard 112.

As shown in
In one embodiment, curved pedal 130 may have an actuatable region 135 at a top surface 136 of curved pedal 130. Where this is the case, bottom surface 137 may be disposed opposite top surface 136. Thickness of curved pedal 130, i.e., the dimension shown in
Although aluminum has been mentioned by way of example, curved pedal 130 may be made of any suitable material, including steel or other suitable metal, thermoplastic and/or thermosetting resin, wood, glass, ceramic, and/or the like, and may comprise any suitable laminated and/or composite material(s). Curved pedal 130 may be cast, machined, molded, formed in a vice or other such device, or manufactured and/or shaped by any other suitable technique.
Length of actuatable region 135 in length direction 132 is preferably at least long enough to permit comfortable actuation by the foot of a typical player, or by the feet of various players who may range in age from child to adult. For example, in one embodiment, length of actuatable region 135 in length direction 132 might be 5 inches to 20 inches. When length of actuatable region 135 is 5 inches to 20 inches, this may provide good but not excessive leverage for comfortable and responsive actuation of curved pedal 130. In a preferred embodiment, length of actuatable region 135 in length direction 132 is substantially longer than the foot of a typical player so as to permit increased leverage and facilitate various sliding actuation techniques. For example, in one embodiment, length of actuatable region 135 in length direction 132 is preferably not less than 12″, more preferably not less than 14″, and still more preferably not less than 16″. Actuatable region 135 is described further below with reference to
There is no particular limitation with respect to width of curved pedal 130 in width direction 133, it being sufficient that width of curved pedal 130 in width direction 133 be such as to permit comfortable actuation by the foot of a typical player, or by the feet of various players who may range in age from child to adult. Note that there is no objection to employment of a curved pedal 130 of nonuniform width; for example, there is no objection to employment of a curved pedal 130 in which width varies with position in length direction 132. For example, width of curved pedal 130 in width direction 133 may vary to accommodate the varying width of a typical foot. Furthermore, width of curved pedal 130 may narrow near the heel end and/or toe end of curved pedal 130 for convenience of mounting in pedal assembly 110 and to provide clearance with respect to support posts 124 and/or other parts.

In some embodiments, the profile of curved pedal 130 may be or approximate a sinusoidal curve in length direction 132 over at least a portion of actuatable region 135.
Where curved pedal 130 has such a sinusoidal profile, wavelength in length direction 132 is preferably on the order of or longer than the length of the foot of a typical player.

Whereas curved pedal 130 shown in
That is, in embodiments in which there is a central concavity 150 and/or a concavity 150 disposed between two convexities 140, 160, it may primarily be the central concavity 150 that serves to locate or orient the foot, while the convexities 140, 160 to either side thereof might typically primarily serve to receive striking force from the heel and/or toe. This being the case, in such an embodiment, it may be that it is primarily only the central or interior first convexity half-lobe 144d which is disposed between extremum 141d and inflection point 145d of first convexity 140d that is required for actuation, and it may be that it is primarily only the central or interior second convexity half-lobe 164d which is disposed between extremum 161d and inflection point 165d of second convexity 160d that is required for actuation.
For this reason, actuatable region 135d of curved pedal 130d is shown in
That is, actuatable region 135d of curved pedal 130d in the embodiment shown in
In one embodiment, actuatable region 135d preferably extends peripherally not more than 25%, more preferably not more than 15%, and most preferably not more than 10%, past first convexity extremum 141d. In one embodiment, actuatable region 135d preferably extends peripherally not more than 25%, more preferably not more than 15%, and most preferably not more than 10%, past second convexity extremum 161d.
And in an embodiment in which it is desirable that that convex portion(s) 140, 160 be at least minimally well-defined, actuatable region 135d in such an embodiment preferably extends peripherally not less than 15%, more preferably not less than 10%, and most preferably not less than 5%, past first convexity extremum 141, and/or actuatable region 135d in such an embodiment preferably extends peripherally not less than 15%, more preferably not less than 10%, and most preferably not less than 5%, past second convexity extremum 161d.

Furthermore, as described with reference to
Moreover, curvature profile need not be uniform throughout actuatable region 135 along length direction 132 of curved pedal 130 it being possible, for example, to employ respectively different curvature profiles at curved portions 140, 150, 160. Furthermore, curvature profile need not be uniform within each of respective curved portions 140, 150, 160, it being possible, for example, to employ different curvature profiles at respective half-lobe(s) 144, 154, 164 therewithin.
Note that the present invention is not limited to the working examples described with reference to
Note further that although working examples shown in
As described above, curved pedal 130 of various embodiments of the present invention may be mounted in pedal assembly 110 for use in drum set 100, for example.
Curved pedal 130 mounted in pedal assembly 110 for use in drum set 100 in accordance with embodiments of the present invention may facilitate pedal-actuated drumming and/or may make pedal-actuated drumming less tiring or more comfortable, especially when employing techniques such as the sliding technique and/or the heel-toe technique.
Furthermore, the curved shape of curved pedal 130 in accordance with some embodiments may allow a player to quickly and reliably locate his or her foot by the “feel” of curved pedal 130.
Moreover, because curved pedal 130 in accordance with some embodiments may be a good match for the shape of the foot, employment of curved pedal 130 may make it possible to achieve more rapid and powerful striking of the drum with less movement of the foot and/or ankle than is the case conventionally.
In addition, the curved shape of curved pedal 130 in accordance with some embodiments may allow the foot—and in particular the heel of the foot and/or the ball of the foot—to strike curved pedal 130 at an angle more nearly perpendicular to top surface 136 thereof, making it possible to improve the leverage or efficiency with which force is transferred from the player's foot to curved pedal 130, and/or permitting stronger and/or less tiring performance.
Furthermore, the smoothly varying contour of curved pedal 130 in some embodiments may be advantageous for players who employ bare feet or who wears socks but no shoes or who wears thin shoes or other such foot coverings for improved comfort and sensitivity in locating the foot on curved pedal 130.
Moreover, because actuatable region 135 of curved pedal 130 in some embodiments is substantially longer than the foot of the player, this may not only permit increase in leverage about the fulcrum of heel hinge 114, permitting more powerful and/or less tiring playing, but may also facilitate more sustained sliding along length direction 132 of curved pedal 130. In addition, a pedal substantially longer than the foot of the player may also accommodate multiple striking locations beyond the basic heel-toe striking positions employed conventionally.
Referring now to
At drum set 100, pedal assembly 110 may be used to play a drum 103 or high-hat cymbals 104, for example, in any suitable manner. For example, where pedal assembly 110 is used to operate bass drum 103, pedal assembly 110 may be assembled in such fashion as to permit pedal assembly 110 to cause beater 115 to strike vertically standing drum 103 or a horizontally standing drum when curved pedal 130 is depressed.
In some embodiments, a player may use pedal assembly 110 to generate a single drum beat. At such time, when the player uses his or her foot to operate pedal assembly 110, the foot may in general be positioned at any arbitrary location along top surface 136 of curved pedal 130 at the time that curved pedal 130 is depressed. For example, the foot may be positioned as shown in
In some embodiments, a player may use pedal assembly 110 to generate a doublet, or two consecutive drum beats. A doublet may be generated in various ways. For example, a player may simply repeat one of the foot movements mentioned above to generate a single drum beat twice in rapid succession. One advantage of some embodiments of the present invention is that it facilitates production of two consecutive drum beats in one foot motion cycle. When two consecutive beats are produced by one foot motion cycle, rapid consecutive beats may be easily achieved.
For example, in accordance with one or more embodiments of the present invention, a player may use any of various sliding techniques. In accordance with one such sliding technique, a player might first depress curved pedal 130 using his or her toe to generate a first stroke, slide his or her foot along length direction 132 of curved pedal 130, and then depress curved pedal 130 again using his or her toe to generate a second stroke. For example, a foot may be positioned for a first toe stroke as shown in
One advantage of at least some embodiments of the present invention is that the curved top surface 136 of curved pedal 130 may be better suited for foot sliding motion and therefore permit easier and less tiring generation of doublets, for example, as compared with a conventional flat pedal.
For example, when toe positions for two consecutive toe strokes are in a curved region of curved pedal 130, e.g., within first concavity 150, the curved shape of top surface 136 of curved pedal 130 may allow a player to more easily slide his or her toe forward or backward along length direction 132 as the toe depresses curved pedal 130.
Furthermore, employment of a curved pedal 130 having smoothly varying slope within at least a portion of actuatable region 135 and/or within the entire actuatable region 135 may make it possible for a player to be able to feel on his or her foot a gradual local angle shift, i.e., slope change, of curved pedal 130 during foot sliding motion, and a player may use this shift as an indicator to understand where his or her toe is positioned during a foot motion cycle. The shift that may be felt on a player's foot may make reproducing a foot motion cycle easier for the player. In particular, where curved pedal 130 has second convexity 160, the curvature of second convexity 160 may provide further toe positioning guidance. Thus, the smoothly varying slope of curved pedal 130 may allow a player to better rely on the feel of the foot and to eliminate or reduce the need to focus on how far the foot should slide, which may make generating a doublet, for example, more reproducible, less tiring, and more enjoyable.
Thus, one advantage of at least some embodiments of the present invention is that curved pedal 130 may make foot tilting motion and hence doublet generation easy and less tiring as compared with a conventional flat pedal. For example, when curved pedal 130 has at least one convexity 140, 160, this may permit a player to be better able to feel on his or her toe a gradual local angle shift, slope change, within first convexity 140, so as to allow easy positioning of a heel for a heel stroke, for example.
As another example of a technique that may be employed, a player may use a heel-toe technique and/or toe-heel technique.
In one such heel-toe technique, a player may first depress curved pedal 130 with his or her heel to generate a first stroke, tilt his or her toe down, and then depress curved pedal 130 with his or her toe to generate a second stroke. For example, a heel may be positioned for a first stroke as shown in
In one such toe-heel technique, a toe stroke may be a first stroke and a heel stroke may be a second stroke. For example, the toe may be positioned for a first stroke as shown in
In some embodiments, a player may use pedal assembly 110 to generate triplets, or three consecutive drum beats. Triplets may be generated in any of various ways. For example, a player may simply repeat the foot movement mentioned above for generating a single drum beat three times. One advantage of some embodiments of the present invention is that it facilitates production of three consecutive drum beats in one foot motion cycle. When three consecutive beats are produced by one foot motion cycle, very rapid consecutive beats may be easily achieved. Furthermore, such a foot motion cycle may be repeated as many times as desired to generate more than three consecutive beats.
It was unexpectedly found by the present inventor that pedal assembly 110 comprising curved pedal 130 makes it possible to easily combine heel-toe techniques (or toe-heel techniques) with sliding techniques for easy generation of triplets, for example.
In accordance with such a combined technique, a player may first depress curved pedal 130 with his or her toe to generate a first stroke, tilt his or her toe down, depress curved pedal 130 with his or her toe to generate a second stroke, slide his or her foot in length direction 132, and then depress curved pedal 130 again with his or her toe to generate a third stroke. For example, a foot may be positioned for a first stroke as shown in
One advantage of at least some embodiments of the present invention is that curved pedal 130 may make generating triplets easier and less tiring as compared with a conventional flat pedal.
Presence of first convexity 140, first concavity 150, and/or second convexity 160 at curved pedal 130 may facilitate utilization of various sliding and/or heel-toe techniques.
Furthermore, actuatable region 135 of curved pedal 130 may be longer than the corresponding length in a conventional flat pedal. Where this is the case, the greater length of curved pedal 130 may provide space sufficient to allow a player's foot to perform ankle tilting and/or foot sliding motions in sequence, allowing greater degrees of freedom in combining toe-heel techniques and sliding techniques, and making it possible to more easily generate triplets, for example.
Although various foot positions have been shown in
Where pedal assembly 110 is used to play high-hat cymbals 104, there is no particular limitation on the manner in which this may be carried out; for example, use of pedal assembly 110 to play high-hat cymbals 104 may be generally similar to use of pedal assembly 110 to play a drum 103 as described above.
Because bass drum 103 in accordance with embodiments of the present invention may permit faster playing than would be possible with a conventional flat pedal, this may allow more versatility in playing than was conventionally possible.
For example, whereas with a conventional flat pedal a player might have been forced to employ two pedals on one drum to achieve a certain degree of frequency of repetitions in striking the drumhead, curved pedal 130 in accordance with embodiments of the present invention may allow such a player to achieve comparable frequency of repetitions with a single curved pedal 130, thus freeing up the other foot to play another drum 103 and/or high-hat cymbals 104. An arrangement suitable for such manner of playing is shown in
Note that a singled curved pedal 130 in accordance with embodiments of the present invention may be used to play multiple instruments through use of a pedal assembly 110 in combination with various linkages may permit tandem and/or parallel playing. Similarly, multiple curved pedals 130 in accordance with embodiments of the present invention may be used in pedal assemblies 110 in combination with various linkages to strike the same and/or different instruments. One such arrangement is shown in
Note that curved pedal 130 and pedal assembly 110 are not limited to employment in bass drums 103, percussion instruments 102, drum sets 100, or musical instruments, but may be applied for use in any of a wide variety of applications where dexterity, responsiveness, and comfort are desired, especially when a pedal is to be operated for an extended period of time. Curved pedals 130 and pedal assemblies 110 in accordance with various embodiments of the present invention are particularly useful for generating rapid and/or repeated mechanical motions.
In some embodiments, such mechanical motion may be employed for playing a percussion instrument or non-percussion musical instrument. In one embodiment, such mechanical motions may be transmitted to an instrument directly when part of a pedal assembly physically comes in contact with an instrument. In another embodiment, such mechanical motions may be transformed into another form of signal, for example an electrical signal, and transmitted to an instrument indirectly.
In some embodiments, such mechanical motion may be employed to operate any of various devices and/or machines. Devices and/or machines in which curved pedals 130 and pedal assemblies 110 in accordance with various embodiments of the present invention may be employed include, without limitation, musical instruments, games, video games, toys, playground equipment, automobiles, helicopters, airplanes, backhoes and other such vehicles, construction equipment, and/or heavy equipment, looms, sewing machines, treadles, knitting machines, saws and/or mills, lathes, pumps, and/or other such manufacturing equipment and industrial apparatuses, as well as any of various devices employed in agriculture, forestry, robotics, and/or aerospace, for example. Regardless of field in which the present invention is applied, mechanical motion of foot-actuated curved pedal 130 may be transmitted by way of an assembly similar to pedal assembly 110 to a target device or machine directly or indirectly. Indirect transmission may include, without limitation, electrical transmission. Although the various embodiments of the present invention have been described in terms of an example in which the operator of curved pedal 130 is human, there is no particular limitation to use of curved pedal 130 or to pedal assembly 110 by a non-human, such as a pet or other animal, or by a non-animal such as a robot, for example.
While embodiments of the present invention have been described above, modes of carrying out the present invention are not limited to the foregoing embodiments, a great many further variations being possible without departing from the gist of the present invention.
