Description:
FIELD OF THE INVENTION 
     This invention relates to a hi-hat cymbal stand and particularly a hi-hat cymbal stand allowable to shrink to a small size rapidly to facilitate carrying. 
     BACKGROUND OF THE INVENTION 
     Percussion instruments are essential musical instruments used in concerts. There are many different types of percussion instruments available for generating different audio effect desired. Around the stands for holding the percussion instruments, there are usually also microphone stands or other drum stands. Drummers usually have to play many different types of percussion instruments, and have to step with one foot or two feet the foot pedals located at the bottom of the drum stands or hi-hat cymbal stands to generate required sound while use a spare foot to step the floor to count the beat of the music. In addition, the drummers also have to occasionally strike the cymbals with drumsticks. All this requires the drummer moving their hands and feet swiftly and busily. Hence it is essential to provide the drummers with maximum help and with least possible interference and distractions. However the stands around the drummers for holding percussion instruments and microphones often become sources of interference and impedance. Moreover, the concert tours always have to move to different sites and have to set up rapidly a lot of musical instruments and audio equipment in a limited time period. To make the instruments easy and fast to assemble and disassemble, and smaller sizes to facilitate carrying and transportation become very important. 
     SUMMARY OF THE INVENTION 
     It is therefore a primary object of this invention to provide a hi-hat cymbal stand that has a foot pedal with a detachable bottom plate and a bottom pedal which is turnable to lean on a rod. The bottom plate is engageable with a depressing plate through a fastening element and has two hooks to engage with or disengage from a pivotal axis of a post plate. The stand further has a tripod which may be moved closely to the rod and shrunk to a smaller size by moving an anchor ring up or down on the rod. All this allows the stand to shrink to a smaller size to facilitate carrying and transportation. 
     It is another object of the invention to provide a detachable leg in the tripod around the rod, the sliding plate may replace the detachable leg to couple with two other legs of the tripod to allow the stand standing on the floor steadily and firmly. 
     The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to FIGS. 1 and 2, the hi-hat cymbal stand of the invention mainly includes a rod  10 , a tripod  20  movably coupled with a middle section of the rod  10  and a foot pedal  30  engaging with the bottom end of the rod  10 . 
     The rod  10  has a top end mounting a lower cymbal  11 A. 
     The tripod  20  has two legs  21 ,  22  which have respectively a top end pivotally engaged through fastening elements such as rivets  221 ,  222  with a lug  121  extending from the periphery of an anchor ring  12 , and another leg  23  which has a top coupling head  232  with an aperture  233  formed thereon. The coupling head  232  is pivotally engaged with another lug  121  on the anchor ring  12  through a screw bolt  231  running through the aperture  233  and another aperture  122  formed on the lug  121 . The screw bolt  231  is fastened by a screw nut  234  (referring to FIG.  4 ). The anchor ring  12  has a center opening  123  to couple with the middle section of the rod  10  and has a screw bore  124  to engage with a set screw bolt  125  for fastening the tripod  20  to the rod  10 . The legs  21 ,  22 ,  23  have respectively a middle section pivotally engaged with a rocker arm  24 ,  25 ,  26 . The rocker arms  24 ,  25  have respectively a bottom end pivotally engaged through fastening elements such as rivets with a pair of chucking lugs  131  located on a periphery of a tube sleeve  13  which is coupled with a lower section of the rod  10 . The rocker arm  26  of another leg  23  has a chucking head  261  at the front end to couple with another chucking lug  131  of the tube sleeve  13  from outside, and is fastened by a screw bolt  262  through an aperture formed on the chucking head  261  and an aperture  132  formed on another chucking lug  131  on the tube sleeve  13 . The screw bolt  262  is fastened by a screw nut  263  (referring to FIG.  5 ). 
     The foot pedal  30  includes an upright post  31  and a tilted pedal plate  32 . The post  31  has a top section coupled with a bottom end of a tube  311 . The tube  311  has a hollow interior to house a linking bar  33  which has an axle  331  running through the hollow interior of the rod  10  and a top end  332  exposed outside the top end of the rod  10 . 
     The linking bar  33  is connected to a chain  321  located at a rear side of the pedal plate  32  so that the tilted pedal plate  32  may be depressed to move the axle  331  downwards to drive an upper cymbal  11 B hitting the lower cymbal  11 A to generate sound desired. The pedal plate  32  has another end pivotally engaged with a bottom plate  34 . The bottom plate  34  has a front end which has two sides forming respectively a hook  341 . The bottom plate  34  further has two apertures  342  formed thereon and two upward wing plates  343  located at two sides thereof. On the bottom plate  34 , there is a depressing plate  35  located between the two wing plates  343 . The depressing plate  35  has a front flange  351  pressing a horizontal post plate  312  of the post  31 . The depressing plate  35  further has a jutting ledge  352  extending upwards from a middle section thereof to allow users to move the depressing plate  35  forwards or rearwards with hands. The depressing plate  35  also has two adjusting slots  353  located on the left and right side thereof. A fastening element such as a screw  354  may be deployed to run through the aperture  342  of the bottom plate  34 , an elastic element  355  and a washer, then run through the adjusting slot  353  of the depressing plate  35  and a washer to engage with a wing nut  356  for fastening (referring to FIG.  3 ). By means of aforesaid construction, the front flange  351  of the depressing plate  35  may depress the horizontal post plate  312  of the post  31 . The depressing plate  35  has another end extending downwards to form a foot flange  357  to rest on the top surface of the bottom plate  34 . The post  31  further has a fastening aperture  313  located respectively on the left side and right side thereof to engage with a screw bolt  314 . The screw bolt  314  may engage with the hook  341  for fastening the bottom plate  34  to the fastening aperture  313 , thereby to connect the post  31  with the bottom plate  34 . The post plate  312  further has two apertures  315  located on two sides thereof to match screw bores  344  located on two sides of the bottom plate  34  for engaging with a screw bolt  316  to fasten the two. The screw bolt  316  has the bottom end contact the floor to reinforce anchoring effect of the bottom plate  34 . 
     When drummers are on concert tours at different locations, the carrying musical instruments and supporting stands and brackets should be folded rapidly and packed in small sizes whenever possible. Through the foot pedal  30  structure of the invention set forth above, when there is a need for folding (referring to FIGS.  3 A through  3 D), the wing nuts  356  may be unfastened first, then move the depressing plate  35  rearwards by means of the ledge  352  with the adjusting slots  353  moving rearwards about the screws  354 . The post plate  312  of the post  31  may be separated from the depressing plate  35 , and the hook  341  of the bottom plate  34  may be moved to disengage from the screw bolt  314 , the bottom plate  34  thus may be moved and lean towards the periphery of the post  31  (as shown in FIG.  6 ). Moreover, the set screw bolt  125  may be unfastened to allow the anchor ring  12  moving upwards so that the rocker arms  24 ,  25 ,  26  may be moved closely towards the rod  10 . Then the set screw bolt  125  may be fastened again to anchor the tripod  20  around the rod  10  in a small size to facilitate carrying and transportation. 
     It is to be noted, the screw bolt  231  of the leg  23  is movably fastened to the anchor ring  12  and may be detached easily. When there is a need to set up another drum stand or other instrument stand beside the hi-hat stand, or drummers want to move the foot across the pedal plate  32  frequently, the three legs of the tripod  20  that space  120  degrees may become an impedance to operations, then the leg  23  may be detached and removed. And the bottom plate  34  of the foot pedal  30  may couple with two other legs  21 ,  22  to form a steady support for the rod  10  on the floor. And more space may be spared around the rod  10  to accommodate more instrument stands required. The anchor ring  12  and tube sleeve  13  also may be turned simultaneously around the rod  10  to adjust the angles of the legs  21 ,  22  connected to the anchor ring  12  and tube sleeve  13  relative to the foot pedal  30  until meeting drummers&#39; requirements for smooth operations and firm support.
