However, in the above-mentioned instrument support assembly, to adjust the angle of the rotating elbow 80 relative to the elbow base 801, one has to engage the teeth of the rotating block 802 and the elbow base 801 in order to fix it. The engaging positions of the teeth have a fixed span. Therefore, one cannot arbitrarily change the angle and fix it. This is a restriction. Besides, the elbow base 801 is fixed on the rod 82 of the support frame. Thus, to adjust the cymbal 81 horizontally, one has to release the rod 82 on the support frame and rotate the rod 82 for the cymbal 81 to rotate to the left or right. Therefore, rotating the cymbal 81 with respect to a vertical axis and a horizontal axis have to be done separately. This usually involves several adjustments back and forth in order to find a best orientation. It is very time-consuming.
Consequently, both of the above-mentioned two conventional instrument support assemblies have the problem of inconvenient in adjustments. It is thus an objective of the invention to solve this problem.
In view of the foregoing, the invention provides a joint instrument support assembly to make the orientation adjustment of an instrument on the support frame more quickly.
The disclosed joint instrument support assembly includes: a rotating elbow, a cylindrical rotating block, a sliding block, a pad, and a fastening element.
Both sides of the rotating elbow have an ear part, respectively. A groove is formed between the two ear parts. One ear part has a circular hole to communicate with the groove. Both ear parts are formed respectively with a circular wall toward the groove. The circular walls are symmetric and have an outer diameter larger than the circular hole.
The cylindrical rotating block goes from the circular hole of the ear part through the groove and urges against the other ear part. It is restricted to rotate within the two circular walls. The rotating block goes through an accommodating room along the radial direction. The rotating block is formed with an axle hole through a sidewall of the accommodating room. The other sidewall has a recess. The rotating block is formed at the bottom of the recess with a connecting hole. A rod on the instrument support frame goes via the axle hole into the rotating block. It goes through the accommodating room and into the recess. The rod urges against the bottom of the recess by its end surface. The end surface of the rod has a screw hole. A limiting element with an outer thread goes through the connecting hole and fastens in the screw hole. This positions the rod and allows it to pivotally rotate within the rotating block.
The sliding block is disposed in the accommodating room to shift forward and backward. The sliding block has a through hole corresponding to the axle hole and for the rod to go through. It further has an outer thread part protruding toward the rotating block.
The pad is disposed on the outer thread part, with its two ends striding on the edges of the two circular walls. It is allowed to slide along the arcs of the two circular walls.
The fastening element is locked on the outer thread part outside the pad. It guides the sliding block to move within the accommodating room and urge the rod against the rotating block.
The invention will become more fully understood from the detailed description given herein below illustration only, and thus is not limitative of the present invention, and wherein:
The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

This embodiment provides a joint instrument support assembly for a vertical support frame 1 to fix and adjust a cymbal 2. It includes: a rotating elbow 3, a cylindrical rotating block 4, a sliding block 5, a pad 6, and a fastening element 7.
Both sides of the rotating elbow 3 have an ear part 31, 32, respectively. A groove 33 is formed between the two ear parts 31, 32. The ear part 31 has a circular hole 34 to communicate with the groove 33. Both ear parts 31, 32 are formed respectively with a circular wall 35 toward the groove 33. The outer edges 351 of the circular walls 35 are symmetric and have an outer diameter larger than the circular hole 34.
The cylindrical rotating block 4 goes from the circular hole 34 of the ear part 31 through the groove 33 and urges against the other ear part 32. It is restricted to rotate within the two circular walls 35. The rotating block 4 goes through an accommodating room 4 and an axle hole 42 along the radial direction. The accommodating room 41 and the axle hole 42 are roughly perpendicular to each other. One rod 11 connected with the instrument or support frame goes through the axle hole 42 into the rotating block 4. The rod 11 goes through the accommodating room 41 and connects to the rotating block 4. The rod 11 can rotate with respect to the rotating block 4.
On the rotating block 4, the axle hole 42 goes out of a sidewall of the accommodating room 41. The other sidewall has a recess 43. A connecting hole 44 goes through the bottom of the recess 43. A rod is mounted on the support frame 1 of the cymbal 2. The rod 11 goes via the axle hole 42 into the rotating block 4. It goes through the accommodating room 41 and into the recess 43. The rod 11 urges against the bottom of the recess 43 by its end surface. The end surface of the rod 11 has a screw hole 111. A limiting element 12 with an outer thread part 121 goes through the connecting hole 44 and fastens in the screw hole 111. This positions the rod 11 and allows it to pivotally rotate within the rotating block 4.
The sliding block 5 is disposed in the accommodating room 41 to shift forward and backward. The sliding block 5 has a through hole 51 corresponding to the axle hole 42 and for the rod 11 to go through. It further has an outer thread part 52 protruding toward the rotating block 4.
The pad 6 is disposed on the outer thread part 52, with its two ends striding on the edges 351 of the two circular walls 35. It is allowed to slide along the arcs of the two circular walls 35.
The fastening element 7 is locked on the outer thread part 52 outside the pad 6. It guides the sliding block 5 to move within the accommodating room 41 and urge the rod 11 against the rotating block 4.

In comparison with the conventional instrument support assembly, the disclosed rotating elbow 3 does not involve any tooth structure. Thus, the rotating elbow 3 does not have limitation in angle, rendering a better freedom. Moreover, the disclosed rotating elbow 3 allows the simultaneous adjustment of the cymbal 2 in the horizontal and vertical directions relative to the rod 11. Therefore, one does not need to adjust several times as in the prior art. This largely shortens the adjusting time, making the adjustment easy and fast.
Of course, the invention has many other embodiments that differ only in details. Please refer to

The small-diameter section 112 of the rod 11 in this embodiment is slightly longer than the axle hole 42 of the rotating block 4. The limiting element 12 uses its outer thread part 121 to go through a pad 122 and locks onto the screw hole 111 of the rod 11. The annular diameter of the pad 122 is greater than the axle hole 42.

From the above description of various embodiment, the disclosed joint instrument support assembly is seen to have very wide applications. In addition to the embodiments disclosed herein, other supports whose vertical and horizontal positions need to be adjusted can be achieved quickly and conveniently using the disclosed rotating elbow.
