ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a hi-hat cymbal and particularly a hi-hat cymbal that has a dual-foot or tripod cymbal stand, which may be flexibly positioned on various performing, sites for use.
FIG. 1
shows a conventional hi-hat cymbal, which has a tripod stand supporting two cymbals at the top end and a foot, pedal at the bottom. By stepping the foot pedal, the two cymbals may be actuated to hit against each other for producing sound desired. The tripod stand has three feet, which may be extended around a circular perimeter to securely hold the cymbals on the floor.
The hi-hat cymbal usually has to couple with drum set at the performance sites, and they take relatively large floor space. When performance sites are outdoors on grass field or with no even ground surface, the three feet of the tripod stand cannot stand steadily.
How to resolve the problem set forth above for the hi-hat cymbal to be firmly supported on any performance sites without taking too much floor space is one of the issues musical instrument manufacturers are now pursing.
SUMMARY OF THE INVENTION
It is an object of this invention to provide an adjustable foot structure for hi-hat cymbal that has a base and a movable foot which may be folded for storing and extended for use, and may be adjusted to form different configurations to suit different performance sites to support the hi-hat cymbal steadily.
It is another object of this invention to provide an adjustable foot structure for hi-hat cymbal that has a base and a movable foot which may be folded for storing and extended for use, and may be coupled with a drum set to facilitate playing.
In order to achieve aforesaid objects, the adjustable foot structure according to this invention includes a base, a cymbal stand and a movable foot pivotally engaged with the base and cymbal stand. The base has a stub at one end and a frame at another end. The movable foot includes a rod which has a screw section at one end and a transverse hole at another end, an adjustable knob and an adjusting ring engaged respectively with the screw section, a linkage means having a linkage beam which has two ends respectively and pivotally engaged with a first anchor member and a second anchor member for engaging with the stub and rod, and a sleeve located above an opening of the frame for pivotally holding the tube. The sleeve has two fingers for pivotally engaging with the transverse hole of the rod.
By means of the structure set forth above, the adjust knob may rest on the ground and the rod may be swiveled about the tube through the sleeve, and the movable foot and the stub form an adjustable angular connection through the linkage means such that the movable foot may be folded for storing or extended for use.
