Preferably, neonychium is provided with at described contact plate lower surface.
Preferably, be provided with the framework positive stop lug boss of at least one at framework rear, the foot-operated box side of mellotron can be withstood.
Advantageous Effects of the present utility model is: foot keyboard height-increasing device can meet the needs that height deficiency plays colony, using foot keyboard height-increasing device can reach the function consistent with using foot keyboard and comfort level, playing freely.
[accompanying drawing explanation]
Foot keyboard height-increasing device using state figure in Fig. 1 embodiment one;
Foot keyboard height-increasing device A place structure enlarged diagram in Fig. 2 embodiment one;
Foot keyboard height-increasing device diagrammatic cross-section in Fig. 3 embodiment one;
The relative position schematic diagram of the foot keyboard height-increasing device in Fig. 4 embodiment one and a mellotron angle.
[embodiment]
In order to make the technical solution of the utility model and technique effect clearly, be described in detail below in conjunction with the embodiment of drawings and Examples to this patent.
Embodiment one:
As shown in Figure 1 to Figure 4, the foot keyboard height-increasing device 100 in the present embodiment, is located at directly over foot keyboard 200, comprises framework 1, height-increasing device keyboard 2, long strength of one's legs arm 3, short strength of one's legs arm 4, framework leg 5, framework positive stop lug boss 6, neonychium 7.
The profile of framework 1 and foot keyboard 200 is suitable, and size of adopting international standards keyboard is advisable, and framework 1 makes player when trampling height-increasing device keyboard, avoids foot keyboard height-increasing device and foot keyboard 200 produces relative displacement.
Height-increasing device keyboard 2 length key is identical with the long-short foot key arrangement regulation of foot keyboard.Long strength of one's legs arm 3 and short strength of one's legs arm 4 comprise bar portion 31 extending longitudinally and are connected to the contact site 32 of bar portion lower end.Long strength of one's legs arm 3 is located at immediately below the long key of height-increasing device keyboard 2, and upper end, long strength of one's legs armed lever portion is fixedly connected with the long key of height-increasing device keyboard 2, and short strength of one's legs arm 4 is located at immediately below the short key of height-increasing device keyboard, and upper end, short strength of one's legs armed lever portion is fixedly connected with the short key of height-increasing device.Contact site 32 is made up of three blocks of plates, one block of flat contact plate, 321, two pieces of clamping plate 322 tilted; Contact plate about 321 two ends are respectively equipped with the clamping plate 322 of an inclination, and the angle between clamping plate 322 is gradually little setting from top to bottom, and the width between two two, clamping plate 322 lower end inwalls is not less than the long key of foot keyboard or the width of short key.Contact plate 321 forms one with clamping plate 322 and contacts screens, and when height-increasing device keyboard is operated, contact site 32 can block the pin key of below foot keyboard, realizes the transmission of pressure.Framework leg 5 is located at immediately below framework 1 edge, is threaded with framework 1, unscrews or tightens framework leg, the height of adjustable framework 1 and bottom surface, until long strength of one's legs arm 3 and the naturally docile length key touching foot keyboard of short strength of one's legs arm 4 are advisable.
In order to avoid scratch or touch the length key surface of colored foot keyboard during the length key contacts of long strength of one's legs arm 3 and short strength of one's legs arm 4 contact site inside surface and foot keyboard, be provided with neonychium 7 at contact site inside surface.Neonychium 7 material that matter is soft is made, area is approximately (35*15*3) mm.
Framework positive stop lug boss 6 is located at framework rear, is no less than one, and can withstand foot-operated box 300 side 301 of mellotron, boss height is 10mm, with the gap adjusted between foot keyboard height-increasing device and foot-operated box 200, prevents from interfering each other.
The foregoing is only the preferred embodiment of this patent, be not limited to this patent, for a person skilled in the art, this patent can have various modifications and variations.Within all spirit at this patent and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in this patent.
