DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Referring now to FIG. 1, there is shown a piano pedal depressing device configured for connection to a piano P, generally referred to as 100. The piano pedal depressing device 100 permits a user to depress a piano pedal D (such as a damper pedal) located at the base of the piano P, using his or her upper leg portion. The piano pedal depressing device 100 includes an adjustable support housing 102, a swivel arm 136, and an actuator assembly 120, which are operatively connected to each other, in order to facilitate depressing the pedal D.

[0012] The piano pedal depressing device 100 has a generally elongate body, adapted for being removably positioned between an undersurface U of the piano keyboard portion and a floor, or horizontal support surface. As illustrated in FIGS. 1 and 2, the support housing 102 includes a plurality of sidewall members 103a, 103b, 103c and 103d forming the body of the support housing 102, a base member 118, and a compressible member 116.

[0013] As illustrated, the compressible member 116 is provided generally at a first or proximal end 132 of the support housing 102, and is configured to engage the underside portion U of the piano's keyboard. The base 118 is provided generally at an opposing distal end 122 of the support housing 102, and configured to engage the floor or surface upon which the piano P is positioned. The compressible member 116 may include a resilient pad and/or a biasing member, such as a spring loaded pressure system, which can be compressed to accommodate a wide variety of conventional pianos having various distances between the piano underside U and the floor.

[0014] The base 118 may include a shock absorbent member, such as a rubber pad, to absorb pressure created when using the device 100, and to stabilize the piano pedal depressing device 100 on the floor. As illustrated, the base 118 may have an arcuate shaped portion 114 with a gap or opening configured to receive the pedal D therein.

[0015] The actuator assembly 120 includes a dowel rod or shaft 104, that extends substantially along the length of the housing 102. In an embodiment, the actuator assembly 120 further includes a biasing spring 128 and a pivot arm 130 that are connected to the shaft 104. The shaft 104 is configured to provide reciprocating upward and downward movement within the support housing 102. The pivot arm 130, connected to wall 103d, is configured to selectively pivot up and down to facilitate the downward and upward vertical movement of the shaft 104. A lower end of the shaft 104 includes an adjustable member 112 that can be vertically adjusted to lengthen or shorten the shaft 104. It is to be understood that the adjustable member 112 can be padded (e.g., rubber padded) to prevent, such as substantially prevent, the adjustable member 112 from either sliding off of the pedal D or from making a clicking sound once the adjustable member 112 is lowered against the pedal D.

[0016] In an embodiment, the swivel arm 136 can be connected to a rack and pinion assembly 140 of the actuator assembly 120. The rack and pinion assembly 140 can include a gear member 144 supported by a shaft 148 and a spring member 146. A rack 142 is fixedly connected to the shaft 104. The rack 142 has a plurality of gear teeth 152 configured to engage the gear member 144. A spring 146 is connected to the gear member 144. A second shaft member 150 can be provided to support a portion of the swivel arm 136 within the assembly 140.

[0017] The swivel arm 136 can have a first lateral portion 124, a second lateral portion 108, and a generally angled portion 106 that extends between the first lateral portion 124 and the second lateral portion 108. The second lateral portion 108 can be configured to have an adjustable length to accommodate a variety of individuals. The second lateral portion 108 can be formed from telescoping members, for example. The first lateral portion 124 extends within the housing 102. A connecting member 126 is positioned between the gear member 144 and the first lateral portion 124 of the swivel arm 136. The second lateral portion 108 and the generally angled portion 106 extend outside of the housing 102. A pad or cushion member 110 can be formed generally at the end of the second lateral portion 108.

[0018] The swivel arm 136 is adapted to move in a generally radial direction relative to the shaft 104, when pressed by the user's upper leg. The pad member 110 provides a soft surface against which the user may press his or her upper leg to move the swivel arm 136. For example, movement of the swivel arm 136 can be configured to adjust the position of the gear member 144 in the rack 142 described above. The spring 146 can bias the gear member 144 in an opposing direction than that of actuation. Upon movement of the swivel arm 136 by the user, the shaft 104 is moved to an engaged position. When the swivel arm 136 is released by the user, the pedal member D provides a biasing force to move the shaft 104 up, back to an unengaged or start position. The rack and pinion assembly 140 converts rotational movement of the swivel arm 136 into vertical movement of the shaft 104, as illustrated in FIG. 3. Thus, the swivel arm 136 can be rotated to move the shaft 104 downward inside the support housing 102 and engage the pedal D. It should be understood that while a rack and pinion assembly has been described, the actuator assembly may include any suitable structure to convert rotational movement of the swivel arm into vertical movement of the shaft.

[0019] In operation, the user attaches the piano pedal depressing device 100 to the piano P by aligning the base of the piano pedal depressing device over the pedal D and positioning the compressible member 116 against the underside of the piano P. The piano pedal depressing device 100 is positioned such that the shaft 104 is aligned vertically with the pedal D. A user can press against the pad 110 of the swivel arm with his or her leg, e.g., inner leg, to cause rotation of the swivel arm 136 and, thereby, rotation of the gear member 144. Movement of the gear member 144 allows the shaft 104 to move in a downward direction. The shaft 104 moves downward, engaging the pedal D. Release of the swivel arm 136 permits the biasing force of the pedal D to force the shaft 104, and swivel arm 136 back to an unengaged starting position.

[0020] It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims
