Description

Wooden drum stand

The present invention relates to a wooden drum box fixing frame, and in particular to a fixing frame that can adjust the structure to fit wooden drum boxes of various sizes.

When an orchestra plays music, they often use instruments of different timbres to combine with each other to present a diverse and pleasant performance. Among them, the wooden box drum (commonly known as: Cajon or Kah) is a percussion instrument that has become popular in recent years. Because of its high degree of freedom and ease of use, it is relatively suitable for beginners to learn. In addition, when it is struck, it can produce a timbre and rhythm similar to that of a jazz drum. At the same time, because of its small size, it is easy to carry, making the wooden box drum very popular and often appearing in the performances of major orchestras. The wooden box drum is as its name suggests. It looks like a wooden box with a striking surface, and there is a circular resonance hole on the other side of the striking surface, so that the sound can be expanded and transmitted through the resonance hole.

When a performer plays a cajon, he usually steps on a pedal to drive a hammer connected to the pedal to hit the cajon. As shown in FIG. 8, the cajon striking device 9 disclosed in the patent case No. M570516 of Taiwan discloses a technical means of using a pedal mechanism 91 to drive a hammer mechanism 92 to hit a cajon 93. Since the action of hitting the cajon 41 is relatively simple, the performer chooses to assign the task of playing the cajon 93 to the foot, rather than directly hitting the striking surface of the cajon 93 with the palm of the hand. In this way, the hand can be assigned to play a more complex instrument. Through the pedal mechanism 91 separated from the hammer mechanism 92, the performer can determine the position of the pedal 911 according to the individual's body shape or leg length without changing the position of the hammer 921.

Since the point where the hammer 921 hits the cajon 93 during the performance significantly affects the sound quality, the relative position of the cajon 93 and the corresponding hammer 921 is extremely important to avoid the performance quality being not as good as expected. As shown in Figure 8, the performer connects the cajon 93 and the hammer 921 with a cajon stand 94, which is provided with a screw hole and a corresponding adjustment pin 95. After the performer has installed the cajon 93, he screws the adjustment pin 95 into the screw hole, and pushes one end of the adjustment pin 95 against the outer circumference of the cajon 93 to fix the position of the cajon 93. The cajon 93 and the hammer 921 are connected and fixed by the cajon stand 94, so that the performer can stabilize the relative position of the two and stabilize the performance quality of the cajon 93.

However, performers often need to travel between different exhibition venues to assemble the cajon drum stand before the performance and dismantle it after the performance. Since the components of the traditional cajon drum stand are relatively bulky, the repeated assembly and transportation process is troublesome and laborious. Secondly, cajons have many different sizes, and the width difference between cajons of different sizes can even reach more than 10 cm. When adjusting the drum stand to switch between cajons of different sizes, the process of rotating the adjustment pin is extremely lengthy and inefficient.

On the other hand, as mentioned above, the cajon is equipped with a circular resonance hole, through which the sound can be expanded and transmitted. In a spacious performance venue (such as a concert hall or opera house), performers often need to use a microphone to amplify the sound of the cajon to a sufficient decibel. Therefore, performers usually clamp the microphone to the inner edge of the resonance hole with a stand so that the microphone can collect the sound directly facing the resonance hole. However, clamping the microphone on the inner edge of the resonance hole of the cajon through a support stand will affect the performance quality of the cajon. The microphone support stand will block the resonance structure of the drum sound, which will lead to a difference in the timbre. Considering that the assembly process of the conventional cajon stand is time-consuming and labor-intensive, and the negative impact of the microphone support stand on the timbre, there is still room for improvement.

In view of this, how to improve the above problems is the primary issue that this invention aims to solve.

One of the purposes of the present invention is to provide a wooden box drum stand with a simple structure and easy assembly, which is suitable for repeated assembly by performers. It is especially suitable for professional performers who often perform in different occasions. In addition, when the performer installs wooden box drums of different sizes, the process of rotating the bolts to make the bolts hit the wooden box drums can be completed more quickly, which has the effect of enlarging the screw setting distance, allowing the performer to fix the wooden box drum more quickly.

The second purpose of the present invention is to provide a cajon drum stand with a connecting portion for connecting to a microphone support stand, so that the microphone support stand is connected to the cajon drum stand instead of being clamped on the inner edge of the resonance hole, thereby avoiding the negative impact of the microphone on the performance level of the cajon drum, allowing the cajon drum to play with complete timbre quality.

To achieve the above-mentioned purpose, the present invention provides a wooden drum frame, comprising: a bottom plate, which is in the shape of a strip and has a front end and a rear end formed at both ends of the bottom plate; a front blocker, which is arranged at the front end, and a front blocker is formed on one side of the front blocker facing the rear end; a rear blocker, which is arranged at the rear end, and the rear blocker is provided with a vertical portion, and the vertical portion is provided with an adjustment screw hole passing through; a clamping plate, which comprises an upper edge and a lower edge, the upper edge is pivoted to the vertical portion so that the lower edge can be pivoted relative to the vertical portion, and a rear blocker is formed on one side of the clamping plate facing the front end; and an adjustment bolt, which is screwed in the adjustment screw hole, and one end of the adjustment bolt is abutted against the other side of the clamping plate opposite to the rear blocker, so that the clamping plate can be pushed by the adjustment bolt to pivot.

Preferably, the rear block is provided with a sleeve hole for the rear end to be sleeved, so that the rear block can be slidably sleeved on the rear end, and the rear block is also provided with a fixing screw hole connected to the sleeve hole, and a bolt is screwed in the fixing screw hole, and one end of the bolt is pressed against the outer peripheral surface of the rear end to position the rear block.

Preferably, the front block is connected to the front end by screwing, and the front end has at least two positioning screw holes, and the at least two positioning screw holes are arranged in a straight line along the extension direction of the bottom plate, so that the front block can adjust the distance between the front block surface and the rear block surface by selecting its screwing position.

Preferably, the lower edge of the rear baffle is formed with a smooth arc-shaped abutment portion.

Preferably, a connection portion is formed at the rear end for connecting to a microphone support stand.

Specifically, the connecting portion is a notch, and a connecting end is formed at one end of the support frame. The connecting end is provided with a threaded section and a clamping member is screwed thereon. The threaded section is embedded in the notch, so that the threaded section and the clamping member clamp the rear end from both sides, thereby connecting the connecting end of the support frame and the notch at the rear end. Specifically, the support frame includes a first bracket in the shape of a long rod, a second bracket and a third bracket. The second bracket is pivoted to the first bracket and the third bracket at both ends, and the connecting end is located at the other end of the first bracket that is not pivoted to the second bracket. The other end of the third bracket that is not pivoted to the second bracket is used to connect the microphone holder. The second bracket is composed of two cantilevers arranged in parallel, and a receiving space is formed between the two cantilevers. The first bracket and the third bracket can be pivoted relative to the second bracket and accommodated in the receiving space.

Please refer to Figures 1 to 4, which show the wooden box drum stand 1 provided by the present invention, which is used to connect the wooden box drum 7 and the microphone stand 8. The wooden box drum stand 1 includes a bottom plate 10, a front stopper 20, a rear stopper 30, a clamping plate 40, an adjustment bolt 50 and a support frame 60, wherein:

The bottom plate 10 is in the shape of a strip and has a front end 11 and a rear end 12 at both ends. The front end 11 is provided with three positioning screw holes 111, which are arranged in a straight line along the extension direction of the bottom plate 10, and the rear end 12 is formed with a connecting portion 121, which is a notch 122 in this embodiment, for connecting the support frame 60.

The front blocker 20 is provided at the front end 11, and a front blocker surface 21 is formed on one side of the front blocker 20 facing the rear end 12. In this embodiment, the front blocker 20 is connected to the front end 11 by screwing, and the positioning screw hole 111 to be screwed is determined according to the size of the wooden box drum 7, so that the front blocker 20 is screwed and fixed at different places of the front end 11. In addition, the front blocker 20 also extends forward to form a hammer connection part 22 for connecting the hammer mechanism. Since the hammer mechanism is familiar to those with ordinary knowledge in this field, it is not necessary to elaborate on it here.

The rear block 30 is provided with a sleeve hole 31 for the rear end 12 to be sleeved, so that the rear block 30 can be slidably sleeved on the rear end 12. The rear block 30 is provided with a fixing screw hole 32 connected to the sleeve hole 31. After the rear block 30 is moved along the rear end 12, a bolt is screwed into the fixing screw hole 32 and one end of the bolt is pressed against the peripheral surface of the rear end 12, thereby fixing the rear block 30 at a relative position of the rear end 12. In addition, the rear block 30 is also provided with a vertical portion 33, and the vertical portion 33 is provided with an adjustment screw hole 331 penetrating therethrough.

The abutment plate 40 includes an upper edge 41 and a lower edge 42. The upper edge 41 of the abutment plate 40 extends to form a pivoting portion 411. The pivoting portion 411 of the upper edge 41 of the abutment plate 40 is pivoted on the upright portion 33 so that the lower edge 42 can be pivoted relative to the upright portion 33. A rear baffle 43 is formed on the side of the abutment plate 40 facing the front end 11. The cajon 7 is disposed between the front baffle 21 of the front baffle 20 and the rear baffle 43 of the abutment plate 40. It is worth mentioning that, considering that the material of the wooden box drum is usually not as hard and solid as solid wood in order to emphasize the performance of the timbre and the feel when hitting, in this embodiment, a smooth arc-shaped abutment portion 431 is formed at the lower edge of the rear baffle 43. When the rear baffle 43 abuts against the outer peripheral surface of the wooden box drum 7 with the abutment portion 431 at the lower edge, the arc-shaped abutment portion 431 has a sharper angle and is less likely to leave a pressure mark on the outer peripheral surface of the wooden box drum 7.

The adjustment bolt 50 is screwed into the adjustment screw hole 331 of the upright portion 33. After the performer has installed the cajon 7, he starts to lock the adjustment bolt 50 into the adjustment screw hole 331. Since one end of the adjustment bolt 50 abuts against the other side of the abutting plate 40 opposite to the rear baffle 43, the abutting plate 40 is pushed by the adjustment bolt 50 and swings, and then the rear baffle 43 on the abutting plate 40 abuts against the outer peripheral surface of the cajon 7.

The above is a partial structural description of the wooden drum stand 1 of the present invention. The following will describe the actual assembly process:

First, the positioning screw hole 111 to which the front block 20 is screwed is determined according to the size of the cajon 7. The larger the size of the cajon 7, the farther the positioning screw hole 111 from the rear end 12 needs to be selected. Then, after the front block 20 is screwed to the bottom plate 10, the cajon 7 to be installed is placed between the front block 20 and the rear block 30, and the cajon is pushed against the front block surface 21 of the front block 20. Then, the rear block 30 is pushed to move along the rear end 12 in a straight line. When the rear block 30 hits the cajon 7, a bolt is screwed into the fixing screw hole 32, and one end of the bolt is pressed against the outer peripheral surface of the rear end 12 so that the rear block 30 is fixed. The position relative to the rear end 12 is fixed, and then, the adjustment bolt 50 screwed in the adjustment screw hole 331 is tightened until one end of the adjustment bolt 50 abuts against the other side of the abutting plate 40 relative to the rear baffle 43, so that the abutting plate 40 is pushed by the adjustment bolt 50 and swings. Finally, the adjustment bolt 50 is continuously tightened until the abutting portion 431 abuts against the outer peripheral surface of the wooden box drum 7. In this way, the wooden box drum 7 is fixed between the front baffle 20 and the rear baffle 30. By the way, since the abutting portion 431 is in a smooth arc shape, even if the abutting portion 431 is pressed against the outer peripheral surface of the wooden box drum 7, it is not easy to cause pressure marks.

For more details, please refer to FIG. 4. When the performer locks the adjustment pin 50, one end of the adjustment pin 50 pushes against the abutment plate 40, so that the abutment plate 40 begins to swing relative to the upright portion 33. The key point is that the cajon stand 1 uses the abutment portion 431 of the abutment plate 40 to abut the cajon 7, rather than the adjustment pin 50 of the conventional technique. Initially, the abutment portion 431 abuts against the upright portion 33, and then, as the adjustment pin 50 is spirally advanced, it begins to swing relative to the upright portion 33, wherein the adjustment pin 50 advances a first distance D1 from the upright portion 33 toward the cajon 7, and The pivoting of the pressing plate 40 allows the pressing portion 431 to move a second distance D2. As shown in FIG. 4, the second distance D2 can be enlarged by pivoting the pressing plate 40 relative to the upright portion 33, and the degree of enlargement is positively correlated with the length of the pressing plate 40. In this way, during assembly, the adjustment bolt 50 is locked and advanced by the first distance D1, and the pressing portion 431 actually advances the longer second distance D2, so that the pressing portion 431 can press against the cajon 7 faster, thereby making the process of fixing the cajon 7 faster and improving the shortcomings of the previous lengthy and laborious process of fixing the cajon 7.

Please refer to Figures 3, 5, and 6 again. The above description only details how the wooden box drum stand 1 of the present invention fixes the wooden box drum 7. The present invention also has the function of connecting the microphone holder 8. The detailed description is as follows:

As shown in FIG. 4 , the support frame 60 includes a first support frame 61, a second support frame 62 and a third support frame 63 in the shape of a long rod. The second support frame 62 is pivotally connected to the first support frame 61 and the third support frame 63 at two ends, and the other end of the first support frame 61 that is not pivotally connected to the second support frame 62 is formed with a connecting end 611. In this embodiment, in order to match the notch 122 of the rear end 12, one end of the support frame 60 is formed with a connecting end 611, and the connecting end 611 is provided with a threaded section 612 and a tightening member 612 is screwed thereon. 13. The threaded section 612 is embedded in the notch 122, so that the threaded section 612 and the clamping member 613 clamp the rear end 12 from both sides, thereby connecting the connecting end 611 of the support frame 60 and the notch 122 of the rear end 12. The other end of the third bracket 63 that is not pivoted with the second bracket 62 is used to connect the microphone seat 8. In this way, the rear end 12 of the bottom plate 10 and the microphone seat 8 are connected by the support frame 60, so that the microphone seat 8 does not need to be assembled on the inner edge of the resonance hole, thereby avoiding interference with the resonance structure in the wooden box drum 7.

Furthermore, the second support 62 is composed of two suspension arms 621 arranged in parallel, and a storage space 622 is formed between the two suspension arms 621. When the performer moves the wooden box drum stand 1, the first support 61 and the third support 63 can be pivoted relative to the second support 62, so that the first support 61 and the third support 63 are accommodated in the storage space 622, so that the support frame 60 of the present invention also has the effect of small storage volume.

Through the cajon stand 1 of the present invention, the performer has two adjustment methods when installing cajon drums 7 of different sizes. First, the present invention sets a plurality of positioning screw holes 111, allowing the performer to determine the screw-connected positioning screw holes 111 according to the size of the cajon drum 7, thereby first making a relatively large adjustment to the distance between the front stopper 20 and the rear stopper 30. Then, since the rear stopper 30 is slidably arranged at the rear end 12, the rear stopper 30 is pushed toward the cajon drum 7 along the rear end 12 until the abutting portion 431 of the rear stopper surface 43 abuts against the cajon drum 7, so that the performer can adjust the size error of the cajon drum 7. After making small adjustments, the adjusting bolt 50 is pressed against the clamping plate 40 to press the clamping portion 431 against the outer circumference of the cajon 7, thereby fixing the cajon 7. The present invention can correspond to cajons 7 of different sizes. When the adjusting bolt 50 is pushed forward by the first distance D1 during assembly, the clamping portion 431 actually moves forward by the longer second distance D2, so that the clamping portion 431 can clamp against the cajon 7 faster. This makes the process of fixing the cajon 7 faster, improves the shortcomings of the previous long and laborious process of fixing the cajon 7, and shortens the locking time.

In addition, when transporting the wooden box drum stand 1 of the present invention, the front blocker 20 and the rear blocker 30 can be removed first, and then assembled by bolts after arriving at the performance site. When the support frame 60 is stored, the first bracket 61 and the third bracket 63 can be pivoted and placed in the accommodating space 622, so that the present invention also has the effect of convenient storage and transportation.

Please refer to Figure 7 again, which is the second embodiment of the wooden box drum stand 1 of the present invention. For the convenience of explanation, the components with similar structures are numbered with reference to the first embodiment of the present invention. The structure of the second embodiment of the present invention is roughly the same as that of the first embodiment, and the difference is only that:

The front block 20 is formed integrally by extending from the front end 11 of the bottom plate 10. The front block 20 is provided with a front block surface 21 and a hammer connection portion 22. The front block 20 abuts the wooden box drum 7 from one side with the front block surface 21. At the same time, the hammer connection portion 22 is connected to the hammer structure so that the relative position of the wooden box drum 7 and the hammer structure can be kept fixed. The remaining components such as the rear block 30, the abutment plate 40 and the adjustment bolt 50 are the same as the structure of the first embodiment. Similarly, the rear end 12 can also be equipped with a support frame 60 for the microphone 8.

In the second embodiment of the wooden box drum stand 1 of the present invention, the rear baffle 30, the abutment plate 40 and the adjustment pin 50 interact with each other, allowing the performer to adjust the width of the wooden box drum 7 with the sliding setting of the rear baffle 30, and when the adjustment pin 50 is pushed forward by the first distance D1 during assembly, the abutment portion 431 actually moves forward by the longer second distance D2, so that the abutment portion 431 can abut the wooden box drum 7 more quickly, thereby making the process of fixing the wooden box drum 7 faster, improving the shortcomings of the previous long and laborious process of fixing the wooden box drum 7, so that the second embodiment of the wooden box drum stand 1 of the present invention also has the effect of shortening the locking time.

However, the disclosure of the above embodiments is only used to illustrate the present invention, not to limit the present invention. Any replacement of equivalent components should still fall within the scope of the present invention.

In summary, those familiar with the technology in this field can understand that the present invention can achieve the aforementioned purpose and is in compliance with the provisions of the Patent Law, and therefore the application is filed in accordance with the law.
