| 摘要 | A rhythm device comprising two resiliently interconnected shafts capable of relative movement between two positions. Noise-making means such as cymbals are mounted on each shaft such that sound is produced at one of the two aforesaid positions. | ||||||
| 权利要求 | 1. A musical instrument comprising a first shaft having at one end an interconnecteD second shaft longitudinally slidably engaged therewith for relative movement between a first and second position, at least one longitudinally extending slot provided in said first shaft, a first arm fixed to said first shaft, first noisemaking means fixed to said first arm, a second arm extending through said slot and fixed to said second shaft, second noisemaking means fixed to said second arm and said first and second noisemaking means oriented for mutual contact at said first position. 2. The musical instrument of claim 1, wherein said noisemaking means are cymbals. 3. The musical instrument of claim 1, including resilient means for biasing said shafts to a normal rest position. 4. The musical instrument of claim 3, wherein the normal rest position constitutes mutual contact of the two noisemaking means. 5. The musical instrument of claim 4 wherein said noisemaking means are cymbals. 6. The musical instrument of claim 3, wherein the biasing means is a spring. 7. The musical instrument of claim 6, wherein said noisemaking means are cymbals. 8. The musical instrument of claim 1, including an object engaging foot mounted on the free end of said second shaft for actuation of said shafts for relative movement between said first and second positions. 9. The musical instrument of claim 8 including resilient spring means for biasing said shafts to a normal rest position which is one of said two positions. 10. A musical instrument comprising a first shaft having at one end an interconnected second shaft longitudinally slidably engaged therein for relative movement between a first and second position, at least one longitudinally extended slot provided in said first shaft, a first arm fixed to said first shaft, a first cymbal fixed to the free end of said first arm, a second arm extending through said slot and fixed to said second shaft, a second cymbal fixed to the free end of said second arm, said second shaft having an object engaging foot mounted on the free end thereof for actuation of said shafts for relative movement between said two positions, a spring mounted between the inner end of said second shaft and a position in said first shaft removed from the inner end of said second shaft for biasing said shafts to a normal rest position, and said first and second cymbals oriented for mutual contact at said first position. |
