Portable accessory pedal and support for a musical instrument

Abstract

A foot pedal actuator is secured to legs of a portable musical instrument using a first elongate member having an aperture for a leg to pass through on one end, and an aperture for securing to a foot pedal actuator fastener aperture on the opposite end. A second elongate member has an aperture which is secured to the foot pedal actuator aperture on one end, and a rotatable attachment to the first elongate member along the span of the first elongate member. A third member similar to the first member and fourth member similar to the second member secure the four corners of the foot pedal actuator to two feet of the portable musical instrument, which pass through the leg apertures of the elongate members.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows a perspective view of a musical instrument and a pedal support.

(2) FIG. 2 shows a bottom view of FIG. 1 with a foot pedal actuator mechanically engaged with a left and right pedal support.

(3) FIGS. 3A, 3B, and 3C show side views of the elongate supports and/or support leg or foot pedal actuator apertures of FIG. 1 and FIG. 2.

DETAILED DESCRIPTION OF THE INVENTION

(4) FIG. 1 shows a portable musical instrument 102 such as a piano having support legs 120 and a sustain foot pedal actuator 104 having an a sustain actuator rod 114 for communicating foot pedal commands to the piano 102. Alternatively, the foot pedal 104 may be an electrical switch with an electrical cable or coupling 114 to the console 102. The foot pedal actuator 104 has corner mounting engagements such as threaded holes which receive fasteners such as screws which are threaded through apertures at the foot pedal actuator ends of respective left elongate support member 106A, left mid-span support member 108A, right elongate support member 106B, and right mid-span support member 108B.

(5) FIG. 2 shows a bottom view of the support (viewed from the floor upwards), and provides additional details for the support. The elongate members 106A and 106B have apertures 202A, 202B for encircling support legs 120, with the aperture 202A and 202B diameter being larger than the largest diameter of the leg 120 which passes through the aperture. Apertures 202A and 202B may be less than 3 inches in diameter, or preferably less than 2 inches in diameter to encircle support legs 120. In one example of the invention, the apertures 202A and 202B are approximately 1.125 inches in diameter. The mid-span supports 108A and 108B are fastened along the span of the right elongate member 106A and left elongate member 106B, respectively, where a rotatable attachment fastener 206A, and 206B, respectively provides a hinge point for the mid-span supports 108A and 108B, the rotatable attachment provided to accommodate different foot pedal actuator long axis length. The arrangement of the support system of FIGS. 1 and 2 provides a very sturdy mounting for the foot pedal actuator, which is constrained in position with respect to support leg position, and can no longer be displaced or knocked over during a performance.

(6) In one example of the invention, elongate supports 106A, 106B are equal in length to each other and elongate supports 108A and 108B are of different but equal length to each other, thereby positioning the foot pedal actuator 104 below the midpoint of the centerline of the long axis of the console 102.

(7) In another example of the invention, elongate supports 106A and 106B are different lengths to offset the foot pedal actuator 104 to one side or the other of the midpoint of the centerline of the long axis of the console 102, to comfortably position the foot pedal actuator for left or right foot operation.

(8) Although the lengths of the elongate members need only be sufficient to satisfy the functional stability requirement for the foot pedal actuator, in another example of the invention, the range of lengths of the elongate members, measured from aperture center to aperture center are: 106A: 25-33 inches or substantially 27.5 inches 106B: 22-30 inches or substantially 24.5 inches with 108A and 108B having a length sufficient to maintain the long axis of foot pedal actuator 104 substantially perpendicular to the long axis of console 102. In examples of the invention, 108A and 108B are approximately 10.75 inches and 9.5, respectively, or either one may be in the range of 6 inches to 13 inches from aperture center to aperture center. Alternatively, 106A may be in the range 22-30 inches and 106B may be in the range 25-33 inches, or as required to position a foot pedal actuator in a desired location under a console 102 with respect to the position of the support legs which are encircled by elongate members 106A and 106B.

(9) The elongate members 106A/106B may be attached to mid-span members 108A/108B using a screw and aircraft (locking) nut, or pressed-in fastener or stud, to provide rotatable attachment 206A/206B. Foot pedal actuator 104 may be attached to the elongate members at respective elongate member engagement apertures 204A, 204B, 208A, and 208B using a screw, or captured button fastener 304 with engagement barbs or engagement surfaces for insertion into the foot pedal 104 as shown in FIG. 3C so that foot pedal actuator 104 may be quickly attached and removed, elongate members 106A/108A and 106B/108B folded into a linear arrangement, and conveniently stored into a space saving cardboard tube. Alternatively, to provide an adjustable support assembly for use with a variety of different pianos with different support leg separation distances, the elongate members 106A/106B may have a central slot or a plurality of fastener apertures which are oriented along the long axis of the elongate members 106A/106B such that rotatable attachment 206A/206B may be moved along the central slot or to one of the plurality of apertures to lengthen or shorten the aperture separation distance from 202A to 202B, thereby accommodating a wide variety of support leg separation distances for various pianos. In another alternative embodiment, the support assembly of FIG. 1 is rotated approximately 180 degrees, with the support leg attachments using the front legs 120 of the piano 102 and the foot pedal actuator rotated approximately 180 degrees in attachment so that it is oriented as shown in FIG. 1. In another alternative embodiment, the support assembly of FIG. 1 is engaged to the two left side support legs of piano 102, or to the two right side support legs of piano 102, with the elongate members 106B and 108B attached to the front two fasteners of foot pedal actuator 104, and the elongate members 106A and 108A attached to the rear two fasteners of foot pedal actuator 104. The terms approximately, when applied to angular or linear dimensions, are understood to mean 30% greater or 30% smaller than the stated dimension.

(10) The elongate member 106A and 106B may require additional fastening security with respect to the legs 120 of the musical instrument 102. FIG. 3A shows the side view of the elongate beam 106B with relation to support leg 120, showing a first example of member 106B which is straight. FIG. 3B shows the side view of elongate beam 106B with relation to support leg 120 in a second example where an offset bend 302 is present to offset the support aperture 202A/B from the support surface (such as a floor) on which leg 120 rests. The offset bend 302 may be located 1 to 12 inches from an end of the elongate member, preferably 1-3 inches from the edge of the leg aperture, with the offset 303 preferably at least 0.25 inches, measured with respect to a surface of the elongate member.
