5 Claims.- 1 This invention relates to a pedalextension device for pianos.

The principal object of the invention is to provide an extension device for piano pedals which:

may be used by children and other people of short stature who are unable to reach piano pedals from anormal sitting position.

Afurther object is to provide such a device which may be readily secured to a piano in operative relationship to the piano pedals.

A further object is to provide such a device which has a foot rest of sunicient area to accommodate the feet, and the pedal members of which may be adjusted to various heights above the foot rest.

A further object is to provide such a device which may be used with pianos having Varying spacings between the pedals.

A further object is to provide such a device which assures that a child learning to play the piano will place his feet in substantially the same position that they will assume when he hasv attained his growth.

A further object is to provide such a device which is composed of simple parts, which is easy to adjust and which presents a neat appearance.

The invention is illustrated in a preferredrform in the accompanying drawings, in which:

Fig. 1 is a plan view of the device in position above the pedals of a piano; Fig. 2 is a rear elevation thereof, partially in section; and Fig. 3 is an end elevation, viewing Fig. 2 fromthe left, partially in section.

Referring to the drawings in greater detail, the

device consists of a foot rest 4 which is generally horizontally disposed, and which has a plane surface of sufficient area to accommodate the feet. Supporting means for the foot rest are provided by. a plurality of legs 5, the length of which may be adjusted by means of screws 6, having their heads furnished with pads 1.

A child learning to play the piano very seldom has occasion to use the center pedal thereof. Accordingly, my device is provided with a fastening member, indicated generally at 8, by which it, may be secured to the center pedal 9 of a piano. This fastening member consists of a vertically adjustable element ll], preferably a long bolt extending through an aperture in the foot rest 4, and vertically adjustable with respect thereto by means of a wing nut II. A pedal engaging portion I2 is provided at the lower end of the bolt Ill, this portion preferably being in the form of a flattened stirrup which may be drawn into frictional engagement with the un- "apiano pedal 24.

bers I6 are pivotally secured adjacent the upper ends of the pedal supports M by means of hinges" I7 and extending forwardly therefrom, each of. the pedal members IE preferably being of the same shape as the corresponding outer pedalof.

a conventional piano.

The foot rest 4 accommodates a pair of push; rods l8, each of which is mounted in a laterally; elongated aperture [8a beneath one of the pedal members l6. Each push rod consists of a bushing, l9'which is locked ,in its aperture |8a by means, of a lock nut l9a, an interiorly threaded. tube 20 slidably mounted in the bushing IS, a top pad 2| secured to the upper end of the tube; 20 and adapted to contact the underside of the. pedal member 16, and an extension member 22:.

secured in the. lower end of the threaded tube. 20, the extension member 22 preferably being provided with a rubber foot 23 which rests upon. The extension member I8 is furnished with a wing nut 25 by which it may be locked in position in the tubular member 20...

A coil spring 26 is mounted on the tube 20 be v tween the bushing I9 and the pad 2!, so as to; relieve the return springs (not shown) of the.

piano pedals 24 of the weight of the pedal mem:- bers l6 and push rods 18.

The use of my device is obvious from the foregoing description. The device is placed in po sition in front of the piano, and the height of:- the foot rest is arranged to suit the leg length of the pianist by adjustment of the screws 6. The. pedal engaging member I2 is then hooked beneaththemiddle pedal 9 of the piano and drawn tightly The: push rods I8 are adjusted to register with the.

against it by screwing up the wing nut II.

tain the desired horizontal and vertical adjustment of the pedal members. Lastly, the push rods H! are adjusted to rest lightly upon the piano pedals 24 by setting the adjustment members 22 in suitable positions. Ordinarily the device will always be used with the same piano, so that adjustment of the pedal members and push rods will be infrequent.

While I have shown and described a specific embodiment of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims,

I claim:

1. A piano pedal extension device, comprising; a foot rest having a substantially horizontal plane surface of sufiicient area to accommodate the feet; means for supporting said foot rest; a fastening member by which the device may be secured to a piano; a pedal support secured to the rear edge portion of the foot rest, said support extending above said foot rest and being Vertically adjustable with respect thereto; a pedal member pivotally secured adjacent to the upper end of said pedal support and extending forwardly therefrom; and means for transmitting motion from said pedal member to the pedal of the piano.

2. A piano pedal extension device, comprising: a foot rest having a substantially horizontal plane surface of sufficient area to accommodate the feet; means for supporting said foot rest; a fastening member by which the device may be secured to a piano; a pedal support secured to the rear edge portion of the foot rest, said support extending above said foot rest and being vertically adjustable with respect thereto; a pedal member pivotally secured adjacent the upper end of said pedal support and extending forwardly therefrom; and a push rod slidably mounted in an aperture in the foot rest beneath said pedal member, said push rod furnishing at least part of the support for the pedal member; and a compression spring interposed between the pedal member and the foot rest.

8. A piano pedal extension device, comprising: a foot rest having a substantially horizontal plane surface of sufiicient area to accommodate the feet; means for supporting said foot rest; a fastening member by which the device may be secured to a piano; a pedal support secured to the rear edge portion of the foot rest, said support extending above said foot rest and being vertically adjustable with respect thereto; a pedal member pivotally secured adjacent the upper end of said pedal support and extending forwardly therefrom; a bushing mounted in an aperture in the foot rest beneath said pedal member; a threaded member slidably mounted in the bushing; a pad secured to the top of said threaded member, said pad being adapted to serve as a support for the pedal member; and an adjustment member screwed to the lower end of the threaded member.

i. A piano pedal extension device, comprising:
