ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates generally to musical instruments, more particularly, it relates to an adjustable cymbal stand thereby gap between two cymbals can be regulated rapidly to create various sound effects and a user may have options in use of a whole set or part of this invention.
A generic pedal cymbal stand shown in
FIG. 1
contains an upper and a lower cymbal, which are controlled to tap each other to generate sound. If the gap between the cymbals is adjusted to become wider or narrower, the resonance frequency can be changed. A bearer unit is usually provided to the lower cymbal for bearing an upper cymbal, and similarly, another bearer unit is locked to a positioning rod for the upper cymbal to bear the lower cymbal. This architecture only allows a user to adjust the position of the upper cymbal, excluding the lower cymbal, by unlocking a wing bolt, moving the upper cymbal, and locking the wing bolt again. As the lower cymbal cannot be adjusted rapidly on the spot in a concert meanwhile, to obtain desired percussion timbre is rather difficult, and this is the point that this invention is trying to improve.
SUMMARY OF THE INVENTION
The primary object of this invention is to provide an adjustable cymbal stand, wherein gap of an upper and a lower cymbal can be regulated by adjusting the upper or the lower cymbal or both, and a positioning rod can be sleeve-jointed on top end of a generic cymbal stand as another option.
In order to realize abovesaid objects, the adjustable cymbal stand of this invention comprises: a supporting frame clamped at a generic cymbal stand being provided with an upwardly extended positioning rod; a thread portion formed at a position near the bottom end of the positioning rod; a bearer unit for bearing an upper cymbal being screw-jointed with the positioning rod; the bearer unit having a supporting rod with a winged bolt locked onto the positioning rod of the supporting frame; a bearer unit for bearing a lower cymbal being located under the bearer unit for bearing the upper cymbal, and composed of a regulating seat, wherein a turn knob is protruded laterally on both sides of the regulating seat, a tapped hole is formed in center of the regulating seat for screw-jointing with the thread portion of the positioning rod, and a spiral spring is disposed under the regulating seat for propping against the latter. Abovesaid construction enables a user to adjust the gap between the cymbals easily and rapidly for adjustment of sound timbre. Moreover, the positioning rod is detachable from the supporting frame, wherein a sleeve with a tapped hole and a set bolt can be sleeve-jointed with top end of a generic cymbal stand as another option.
For more detailed information regarding this invention together with further advantages or features thereof, at least an example of preferred embodiment will be elucidated below with reference to the annexed drawings.
