摘要： An electronic keyboard key apparatus includes a longitudinally extending key pivotally mounted on a supporting base and a simulated hammer assembly including a simulated hammer mounted on a hammer shank that is independently pivotally mounted with respect to the key on the base. A jack means is mounted on the key for striking and pivoting the hammer assembly when the key is struck and a preferably flexible bridle for controlling the hammer assembly connects the hammer assembly to the key. A spring is connected between a back end of the key and the base for quickly returning the key to its at rest position. The bridle may be a flexible strap. The simulated hammer may be a metallic cylinder disposed about a first distal end of the hammer shank. A butt is attached to a second distal end of the shank and the butt has a butt end that is bifurcated to form two hinge lugs that are hinged to a single hinge lug of a lug mount fixedly connected to the base. The shank and the butt may be constructed as a single integral member and made of wood as can be the lug mount. The simulated hammer assembly may be mounted above the key and the lug mount is mounted above the key on a first rail. A hammer cushioning means for cushioning and resting the simulated hammer is mounted to the base beneath the simulated hammer and a hammer stop is disposed above the hammer cushioning means such that the simulated hammer engages the stop when the key is struck causing the hammer shank to pivot upwards. The hammer stop may be a U-shaped stop cushion with a circularly bent end, legs extending away from the bent end, and the stop cushion mounted to a stop bar by a clamp channel that clamp the legs between the channel and the stop bar.

摘要： A parallel motion linkage is taught for the sliding keyboard cover of a piano to assure that the sliding keyboard cover, when shifted between its open (key exposing) position and its closed (key covering) position will remain perpendicular to the direction of its motion and will not skew or jam between the sides of the piano case. The structure comprises a pair of bell cranks rotatively mounted to the underside of the sliding keyboard cover near the ends thereof. The bell cranks each have a first short arm, which arms are joined together by a tie rod pivotally connected thereto. The bell cranks each have a long arm to which one end of a connecting rod is pivotally mounted. The free end of each connecting rod is detachably and adjustably affixed to a bracket mounted on its respective side of the piano case.

摘要： An improved combination acoustic-mode and electronic-mode piano is provided which includes a hammer shank stop rail that intercepts the hammer shank, when in the electronic mode, so that the hammer cannot complete its normal travel and cannot strike its corresponding string(s) when its piano key is actuated. The hammer shank stop rail is actuated by an intermediate crank that, in turn, is actuated by a pedal dowel attached to one of the pedals of the piano. When operated in the acoustic mode, the stop rail occupies a position that will not interfere with the hammer shank's movements, and when in the electronic mode, the stop rail intercepts the hammer shank so that its associated hammer will not be able to travel all the way into contact with their associated string. A second embodiment operates the stop rail by use of a cable and cam mechanism. A third embodiment uses a hand-actuator to operate the stop rail via a dowel and intermediate crank. In a fourth embodiment, a fluid-actuated hammer shank stop rail is located in a position similar to the mechanical hammer shank stop rail described hereinabove. The fluid-actuated hammer shank stop rail includes a rigid portion that provides support across the width of the piano and an expandable portion that is resilient and can be enlarged by the use of an internal fluid pressure, which intercepts the hammer shank before the associated hammer can strike their associated string. A fifth embodiment of a combination dual-mode piano is provided that utilizes a spring-loaded wippen-disabler to prevent the wippen from being actuated by the key tail when the associated key is struck. When placed into the electronic mode, the wippen-disabler is rotated into a position in which one of its extended members is forced against the bottom portion of the wippen and raises the wippen high enough into a position so that the capstan screw of the key tail cannot come into contact with the bottom surface of the wippen. In addition, a different portion of the wippen-disabler is rotated so that its associated spring comes into contact with the top of the key tail, thereby providing the person playing the piano with some mechanical feedback that will approximate the feel of a standard key action.

摘要： Means for improving the repetition characteristics of an upright piano action of the type having a hammer for each key, the butt of the hammer being pivotally mounted on a main action rail so that the hammer can be projected from an at-rest position toward a string striking position, a wippen pivotally attached to the main action rail and operatively connected to the key, a jack pivotally connected to the wippen for transmitting the action of the key and wippen to the hammer via the hammer butt to cause the hammer to strike the string when the key is forcibly depressed and a back check serving as an oscillation damper for the hammer. The means for improving the repetition characteristics comprises an adjustable spring and linkage assembly attached at its ends to positions of substantially equal operating displacement on the wippen and the hammer butt. The spring and linkage assembly is adjusted such that, when the hammer is at its at-rest position and during movement of the hammer, wippen and jack to the point of escapement of the jack from beneath the hammer butt, the spring and linkage assembly is substantially unloaded. After escapement of the jack from beneath the hammer butt, relative movement of the wippen and hammer butt loads the spring and linkage assembly to render it capable of supporting the weight of the hammer, so that if the key is partially released and the hammer comes out of check the spring and linkage assembly will support the hammer in an intermediate position permitting the jack to return to its operating position beneath the hammer butt without full release of the key.

摘要： A combination acoustic mode and electronic mode grand piano is provided including a hammer shank stop rail that intercepts the hammer shank when operating in its electronic mode, so that the hammer cannot complete its normal travel to strike its corresponding string(s) when its key is actuated. The positioning of the hammer shank stop rail is actuated by a user-operated control that, when placed into the "acoustic" mode, raises the hammer shank stop rail to a non-engaged position that does not interfere with the normal movements of the hammer shank. When in the "electronic" mode, the control lowers the hammer shank stop rail into an engaged position where it intercepts the hammer shanks of the piano, thereby preventing each hammer head from striking its respective string(s). When in the engaged position, the wire cam also causes an "early escapement rail" to be moved into a location such that flexible "early escapement tabs" are moved into positions just beneath the letoff button of each of the key actions, thereby preventing a harsh "feel" or "touch" as perceived by the human player of the piano. In a second embodiment of a combination dual-mode piano, a hammer head stop rail is provided for an upright piano which intercepts the hammer head when in the electronic mode. When placed into the acoustic mode, the hammer head stop rail is rotated to a non-engaged position that is not within the normal path of the hammer travel. When operated in the electronic mode, the actuating arm is rotated such that the hammer head stop rail becomes positioned directly in the path of travel of the hammer heads of the upright piano where they will impact directly against the stop rail. In the illustrated embodiment, the stop rail comprises a deflectable member that is coated with a sound and vibration absorbing material, such that when the hammer head impacts the stop rail, the deflectable member somewhat displaces, as the hammer head impacts against this member. The hammer head stop rail also includes a sound and vibration absorbing pad that is brought into position against the strings of the piano, thereby tending to dampen any acoustic vibration that may otherwise become induced in the strings.
