Musical instrument drive mechanism that uses steel cables to transmit power

Abstract

A musical instrument drive device that uses a steel cable to transmit power has a drive mechanism and a transmission mechanism. The drive mechanism and the transmission mechanism are connected by a steel cable, so that the transmission mechanism can drive the drive mechanism to move relative to each other via the steel cable. The steel cable is inserted into a sleeve. One end of the sleeve is set on a first fixed seat of the drive mechanism, and the other end of the steel cable is set on a second fixed seat of the transmission mechanism. The two ends of the sleeve have a first end edge and a second end edge, and an elastic extension section covering the steel cable is formed between the first end edge and the first fixed seat or between the second end edge and the second fixed seat.

Claims

1. A musical instrument driving device that uses a steel cable to transmit power, comprising: a driving mechanism having a first base plate, a first upright and a first fixed seat on the first base plate, a first rotating shaft passing through the first upright, and a driving member and a first steel cable rotating member disposed on the first rotating shaft; and a transmission mechanism having a second base plate, a second upright and a second fixed seat on the second base plate, a second rotating shaft passing through the second upright, and a transmission member pivotally mounted at both ends on the second base plate and the second rotating shaft, and a second steel cable rotating member disposed at one end of the second rotating shaft; A steel cable is threaded through a sleeve. One end of the sleeve is mounted on a first fixed base, and the other end of the sleeve is mounted on a second fixed base. The extended ends of the two ends of the sleeve respectively define a first end edge and a second end edge. An elastic extension section covering the steel cable is formed between the first end edge and the first fixed base or between the second end edge and the second fixed base. The steel cable has a first end extending out of the first end edge and a second end extending out of the second end edge. The first end of the steel cable is connected to a first steel cable rotating member, and the second end is connected to a second steel cable rotating member, so that the transmission mechanism can drive the drive mechanism to operate via the steel cable.

2. The musical instrument drive device using a steel cable to transmit power as described in claim 1, wherein, The first steel cable rotating component is connected to a first support arm via a first shaft. The first support arm can be adjusted relative to the first steel cable rotating component at the connection angle, and then positioned via the first shaft.

3. The musical instrument drive device using a steel cable to transmit power as described in claim 2, wherein, The first arm has a first connecting part consisting of a screw hole, and the first end of the steel cable is clamped to the first connecting part by a first fixing member consisting of a screw.

4. The musical instrument drive device using a steel cable to transmit power as described in claim 1, wherein, The second steel cable rotating component is connected to a second support arm via a second shaft. The second support arm can be adjusted relative to the connection angle between itself and the second steel cable rotating component, and then positioned via the second shaft.

5. The musical instrument drive device using a steel cable to transmit power as described in claim 4, wherein, The second arm has a second connecting portion consisting of a screw hole, and the second end of the steel cable is clamped to the second connecting portion by a second fixing member consisting of a screw.

6. The musical instrument drive device using a steel cable to transmit power as described in claim 1, wherein, The first fixing seat and the second fixing seat each have a cover and a base arranged vertically opposite each other. The two ends of the sleeve are respectively inserted between the cover and the base of the first fixing seat and between the cover and the base of the second fixing seat, and are respectively locked to the corresponding cover and base through a locking fastener, so that the two ends of the sleeve are respectively clamped and fixed in the first fixing seat and the second fixing seat.

7. The musical instrument drive device using a steel cable to transmit power as described in claim 1, wherein, The elastic extension extends outward to a length between 1 cm and 10 cm.

8. The musical instrument drive device using a steel cable to transmit power as described in claim 1, wherein, The sleeve has outwardly protruding elastic extensions formed between the first end edge and the first fixing seat, and between the second end edge and the second fixing seat.

9. The musical instrument drive device using a steel cable to transmit power as described in claim 1, wherein, A set of rings is clamped and fixed to the outer periphery of the first end edge and the second end edge respectively.

10. The musical instrument drive device using a steel cable to transmit power as described in claim 1, wherein, The drive component consists of a hammer, while the transmission component consists of a pedal.
