Abstract:
A foot operable percussion instrument producing jingling sounds similar to a tambourine is useable by a solo performer and possesses a wedge-shaped body with an inclined striking surface for the striking by a foot or a portion thereof. The wedge-shaped body is connected to a base plate member by a pair of rigid connectors that together define a fulcrum so that the front portion of the wedge-shaped block pivots downwardly when struck by a foot on the inclined striking surface and rights itself when the foot is lifted. The jingling sound produced is of short duration.

       FIELD OF THE INVENTION 
       [0005]    The present invention relates generally to percussion type musical instruments, and more particularly to foot operable percussion instruments. 
       BACKGROUND OF THE INVENTION 
       [0006]    The tambourine is an ancient instrument that possesses a bent frame with multiple openings that contain small pieces of metal called jingles that clash together and sound when the frame is struck or shaken. The frame can include a stretched drumhead that combines the low sound of a drum with the high sound of the jingles. Commonly, each jingle is disc shaped, has a central aperture and is stacked atop a second jingle, forming a jingle pair. Each jingle pair is retained in the frame by a pin secured at each end to the frame and running co-axially through the jingle apertures. The apertures are sized so that the jingle pairs can freely spin, ride up and down and move slightly angularly relative to the pin. Tambourines are used frequently as a sound enriching accompaniment to other instrumentation that can include among others, fiddles, guitars and drums. Tambourines are especially useful in enriching the sound of minimally instrumented performances. 
         [0007]    Various foot operated percussion instruments possessing tambourine-like elements have been described in the past for purposes of allowing soloists to enrich their sound, including a stand-alone tambourine which is connectable by its frame to a hinged element that when struck by a foot, shakes the tambourine. Other known instruments possess jingles which are mounted within structures affixible to a body part such as a knee, or a foot. While the forgoing types of instruments work well for their intended use, (1) many are relatively large complicated mechanisms that are difficult to pack for performances, (2) others, being attached to a body part, are difficult to control and are too easily sounded by inadvertent body movement, and (3) still others produce a vibratory sustain that is undesirable and not easily attenuated. 
         [0008]    Accordingly, it would be desirable for a foot operable percussion instrument producing a jingling sound to be among other things, (1) compact enough to fit inside an instrument case, (2) of simple and durable construction, (3) unattached to any body part, (4) sensitive enough to sound at the slightest tap of a foot, and (5) capable of producing a sound of short duration for each tap of the foot. 
       SUMMARY OF THE INVENTION 
       [0009]    The present invention is a small foot operable percussion instrument with jingles that can be packed in a guitar case, is very sensitive to tapping movement, and produces an easily controlled sound of short duration when tapped by the foot. Owing to the sensitivity of the jingles, the instrument can be played continually with minimal foot movement and without fatiguing the musician. 
         [0010]    In one aspect, the present invention includes a solid wedge-shaped block having at least one recess on at least one side of the block that houses at least one jingle pair. The wedge-shaped block has top side with an inclined surface defining a striking zone that is downwardly impacted by the foot. A base plate for placement on the floor is beneath the block, and at least one rigid connector defining a fulcrum joins the base plate to the wedge-shaped block. While the distance separating the base plate from the wedge-shaped block is preferably between ¼ inch and 1 inch, most preferably, the distance is ⅜ inch. 
         [0011]    When the inclined surface of the block is struck by the foot, the retaining pin for the jingles is shifted slightly out of its normal perpendicular position relative to the floor, and the jingles are sufficiently disturbed in order to create a sound. Because the pins retaining the jingle pairs only tilt slightly during the impact, the jingles vibrate together, or separate and collapse without noticeable friction. Because the connecting elements between the block and base plate are rigid, no substantial vibration of the block is induced when impacted, and the jingling sounds persist for no more than one second. Although the jingles will sound at every impact of the block, there exists a greater damping effect if the foot or a portion thereof remains in contact with the block immediately following the impact. 
         [0012]    The jingles will sound even when tapped lightly with a finger. However, if the inclined surface is struck powerfully, one end of the wedge-shaped block will strike the base plate producing an audible “click” similar to the sound of a rim shot to a snare drum, in addition to jingling. 
         [0013]    Although the preferred embodiment possesses a solid wedge-shaped block made of pine or a material of similar density, conceivably, the wedge-shaped block can be hollow, and formed from any suitable material having desirable resonant properties; whether wood, plastic, metal or a composite of the forgoing materials. 
         [0014]    Although the preferred embodiment possesses common disc-shaped jingles, other jingling means will no doubt suggest themselves to those skilled in art and having benefit of this disclosure. Accordingly, it is intended that the invention encompass alternate jingling means which are long known in the art. 
         [0015]    Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings wherein by way of illustration and example, a preferred embodiment of the present invention is disclosed.

         [0039]    Referring generally to  FIGS. 1-10 ; a novel foot operable percussion instrument  10 ′ is shown having a generally wedge-shaped block  16  with an underside  14 , and a top surface  20  having an inclined striking zone  18  with an angle preferably between 5° and 25° relative to a floor surface, but most preferably between 10° and 15° relative to the floor surface. The block includes at least one recess  24  at a back side with a pair of jingles  26  residing therein, with a portion of the jingle pair extending beyond an end of the block. A retaining pin  28  is secured at two ends to the block, and passes through the apertures of each jingle pair to secure the pair in place within the recess which is formed by any means such as molding or machining Preferably, the embodiments described herein include jingles which feature irregularities such as small convexities (not shown) that are present on the facing surfaces of the jingles so that a portions of the facing surfaces are separated slightly when the jingles are at rest. When the jingle pair is tossed, formerly non-contacting regions of the jingles clash. This is one reason for the typical “sizzle” sound of jingles. Additionally, the instrument includes a base plate  12  of generally the same width as the block, yet extending out from under the block so that a performer can rest his heel thereon. The base plate has a bottom side with non-skid material such as a rubberized pad, attached thereto (not shown), and a top side which is separated from the underside of the block by at least one rigid connector  22  defining a fulcrum. Preferably, the rigid connectors are two circular spacers of ⅜ inch thickness and no more than ½ inch diameter, with each spacer having a centered aperture, and a fastener  32  passing therethrough to join the base plate to the underside of the block into which fastener  32  penetrates. The fasteners are preferably metal, and can be wood screws, bolts, pins or any suitable replacement. The spacers bridge the gap between the base plate and block. The nexus of the top of the spacer and the contacting underside surface of the block defines the pivot point  30  between the base plate and block. The distance between the top surface of the base plate and the nexus is preferably between ¼ inch and ½ inch. The rigid connectors are connected to the underside of the block at a position substantially corresponding to the balance point of the wedge-shaped block after the installation of the jingle pairs and retaining pins. The rigid connectors permit resilient pivoting movement between the block and the base plate, yet substantially restrict the pivoting to one plane in which the block is tilted rearwardly upon impact with the foot; only to right itself when the foot is lifted. Because the spacers of the connectors  22  are rigid and relatively short in length, there is no sustained vibration of the block which provides a natural damping for the jingles, and produces a shorter duration jingling than occurs even when a tambourine is slapped against a thigh and held tightly thereto in order to damp it. 
         [0040]    When engaging the instrument&#39;s primary sound on alternating beats, it is sometimes natural for the performer to utilize a heel tap on the other alternating beats. A sympathetic jingle sound occurs during the off-beats that is not as prominent as the primary beat sound, but provides an additional level of accompaniment. 
         [0041]    A microphone, transducer, or piezoelectric pickup (not shown) can be temporarily placed or permanently installed at either end of the instrument to amplify the sound produced by the jingles or the click produced when the block strikes the base plate. 
         [0042]    Those skilled in the relevant art will appreciate that the instrument can incorporate more than two sets of jingles  26  shown in the drawing figures, by making the wedge  16  wider and adding a more recesses  24 . 
         [0043]    Those skilled in the relevant art will appreciate that the base plate  12  can be made longer or shorter in length to accommodate the needs of the performer. 
         [0044]    As shown in  FIG. 10 , although not necessary in normal use, a spring  34  can be placed beneath the base plate and the forward end of the wedge-shaped block  16  to counter any possible lag of the wedge-shaped block to right itself after being struck with the foot. In this case, one end of the spring would be inset into a recess (not shown) formed into the bottom surface  14  of the wedge-shaped block; the recess having a greater diameter than the spring, while the other end of the spring is affixed to the top of the base plate. This would allow the forward portion of the wedge-shaped block to still contact the base plate  12  when struck with sufficient force, because the spring would compress into the recess, permitting adjacent areas of the recess on the bottom of the block to contact the base plate. While the spring shown is a coil-type, any sufficiently resilient element such as a leaf-type spring, a rubber bumper, or the like, can be used as long as it permits the wedge-shaped block to strike the base plate. 
         [0000]    Use of the Invention Below are set forth non-limiting examples of use for the present invention and assume that the instrument is placed on the floor. 
       Example 1 
       [0045]    Sound is produced by placing the heel of a foot on the base plate  12  with the toe of the foot poised above the inclined striking zone  18 . The musician then proceeds to tap the toe of the foot against the striking zone while keeping the heel rested on the base plate  12 . 
       Example 2 
       [0046]    Sound is produced by placing the heel of a foot on the base plate  12  with the toe of the foot poised above the inclined striking zone  18 . The musician then proceeds to rock his heel back and forth while maintaining contact with the base plate  12 . This lifts the entire instrument off of the floor and makes a sound when the instrument strikes the ground. 
       Example 3 
       [0047]    Sound is produced by poising the heel of a foot above base plate  12  with the toe of the foot poised above the inclined striking zone  18 . The musician then proceeds to tap the heel and the toe simultaneously downwardly onto the base plate  12  and striking zone, respectively. 
       Example 4 
       [0048]    Sound is produced by placing the heel of a foot on the base plate  12  with the toe of the foot poised above the inclined striking zone  18 . The musician then proceeds to powerfully tap the toe of the foot against the striking zone while maintaining the heel on the base plate  12 . This causes a portion of the wedge-shaped block  16  to strike the base plate producing an audible “click” which accompanies the jingle. 
         [0049]    While the invention has been described by the embodiments given, it is not intended to limit the scope of the invention to the particular forms set forth. For example, although the inclined striking zone is shown as smooth, it is conceivable that ridges, nubs or other non-skid surface treatment be applied thereto. The jingles can vary in diameter and cross-sectional profile to produce different sounds. More than one jingle pair can be installed within each recess while separating the pairs by stops placed on the retaining pins. Accordingly, the description herein is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
