Abstract

Coupling of buttons and resistance elements (magnetic, spring-like, weights or other type) by a mounted under the button rocker, characterized in that the resistance elements can be attached directly to the rocker by miniaturization.

Description

Anyone who wants to prepare for the game of pipe organs, this makes it increasingly on an exercise instrument at home.

In addition to a good sound, it is above all a realistic sense of touch that enables a good transfer of the experienced to the pipe organ of choice. Especially in the case of the widespread pipe organs with mechanical action, the power of the keys is complex. There is a pressure point when opening the valves, which may vary due to the number and type of registers pulled. There is the valve spring, whose force must be overcome, usually a lead weight at the rear key pad end, for returning the depressed key and mechanical coupling. These drastically increase the pressure point as well as holding forces of the selected manuals. Often there is a backlash on the keys before the key end exerts force on the valve. On some organs you also experience a rising key resistance from the high to the low tones. In addition, usually also the pedal has a pressure point.

It is desirable to be able to experience all of these components, some of which change in the current game operation, s.der Übeinstrument.

The only approach that could realize this to date on a non-mechanical organ uses electromagnets (see patents WO 01/39169 A1 and WO 01/39170 A1 from UHT). Disadvantage of this device is the very complex and expensive construction. Each device requires an electromagnet, an electronic key position sensor and an electronic controller. It also creates a significant power consumption by the electromagnet.

Simpler approaches with one-arm keyboards use permanent magnets and are essentially focused on simulating the pressure point. Their key resistors are factory-set and can not be changed during ongoing game operation (see patent EP 0 567 024 A2 from UHT or the company Fatar using Gummihütchen).

An approach that makes at least one spring force component changeable in the current game operation can be found in the patents US 2004/0025673 A1 and DE 37 28 841 A1 , Apparatuses are shown which cause variable spring resistances on the keys by means of a rotatable bar. However, a pressure point can not be simulated in this way.

The basis of our further ideas is the patent of Mr. Olaf Schmidt, 10 2015 000 133. Due to his idea (electrically) to move (twist) barer magnetic rails, an adjustment of the pressure point and holding forces can be made in the current game operation.

Subject of the present invention is a stepless pressure point and holding force adjustment for one-armed keyboards, as well as a pressure point simulation for the pedal. The phenomenon of decreasing forces from the low to high keys of a manual can also be simulated. In addition, a key of the keys can be selected, which, however, can not be changed in the current game mode. The overall structure is comparatively simple, can be realized cost-effectively and consumes little power.

The device described here uses single-arm keyboard manuals as built by Fatar, UHT and other manufacturers (drawing 1a). A spring holds the key in its rest position (not in the drawing). The power transmission between the button ( 1 ) and an underlying rocker ( 2 ) is done via a stamp (screw) ( 3 ), whose rest distance from the front rocker end determines the key blanking path. If a cutting bearing is used for the rocker, the front rocker end can be made concave (drawing 1b) in order to improve the lateral guidance. Via a hole in the front rocker end ( 4 ) can be changed from below with a screwdriver, the key blank. A variable pressure and holding force simulation is now produced using the patent of Mr. Olaf Schmidt, 10 2015 000 133. For this purpose, a rotatable or displaceable rail with attached magnets ( 5 ) under the support of the rear rocker end ( 6 ). A matching, attractive magnet is located above, attached to the rear rocker end ( 7 ). Alternatively, here also a magnetizable material can be attached. This leads to a more pronounced pressure point and less holding power while the button is pressed. By choosing a suitable strength of the rail, a certain torsion can be allowed for the rotatable arrangement, which allows with an adjusting element at each end of the rail from increasing the high to the low tones force. By padding on the bottom of the button ( 8th ), the rocker is caught during the keystroke.

The sound is triggered by another magnet ( 9 ), which is attached to the front rocker end and its way to a Hall sensor unit ( 10 ) passes. So the sound trigger point is linked to the pressure point and not to the absolute key position.

For one-armed keys without spring, a device using the patent application 10 2015 015 385.4 with a microtracture is possible (drawing 1c). In contrast to the previous description, the stamp ( 1 ) now in the rest position of the button already on the rocker ( 2 ). The key blank path is determined by the distance of the head of the microtracture ( 3 ) determined by the rear rocker end. During the free travel, only the force of the weight attached to the rear rocker end ( 4 ).

Another object of the invention is a simple and inexpensive to implement pressure point simulation for Orgelpedaltasten, based on the concept of microtracture (Patent Application 10 2015 015 385.4, drawing 2) and attractive magnetic force. For this purpose, at the rear upper end of a pedal ( 1 ) a magnet ( 2 ) or a magnetizable material. A guide for the microtracture ( 3 ) with magnet ( 4 ) is placed on the frame of the pedal ( 5 ) attached. Over the length of the microtracture and the position of the attachment, the backlash is set.
