Description

Technical Field

[0001] This invention relates to a snare drum snare adjustment device, and more particularly to a snare adjustment device that allows the snare mechanism to be installed on the adjustment device without any hand tools, so that the user can quickly remove the snare mechanism from the adjustment device by hand. Prior Technology

[0002] The snare drum is one of the most common percussion instruments in musical performances. As shown in Figures 1A to 1C, the conventional snare drum 50 is mainly composed of a drum body 51, a sounding mechanism 52, a connecting mechanism (not shown), and an adjusting mechanism 53. The drum body 51 has a hollow drum shell 511 and two drumheads (not shown) connected to the upper and lower ends of the drum shell 511 respectively. The sounding mechanism 52 is located below the drum shell 511 and has two sounding connecting plates 521 arranged at intervals. The two sounding connecting plates 521 connect a plurality of sounding wires 522, so that the plurality of sounding wires 522 are located between the two sounding connecting plates 521. Each sounding connecting plate 521 is connected to a sling 523. The connecting mechanism 53 is set in the drum shell 511 to clamp one of the slings 523.

[0003] As shown in Figures 1B and 1C, the adjustment mechanism 53 comprises four parts: a supporting body 531, a movable body 532, an opening / closing body 533, and a sling connecting body 534. The supporting body 531 is connected to the drum shell 511 of the drum body 51, while the movable body 532 is movably assembled to the supporting body 531 along the Z-axis, allowing the movable body 532 to move linearly relative to the supporting body 531 along the Z-axis. The opening / closing body 533 is connected to both the supporting body 531 and the movable body 532, and can drive the movable body 532 to move along the Z-axis. In addition, the sling connecting body 534 is connected to the movable body 532, so that the sling connecting body 534 can move synchronously with the movable body 532. Furthermore, the sling connecting body 534 is mainly composed of a sling connecting seat 534a, a sling pressure plate 534b, and two pressure plate screws 534c. The pressure plate screws 534c pass through the sling pressure plate 534b to lock it to the sling connecting seat 534a, so that the sling connecting seat 534a and the sling pressure plate 534b can be clamped to the other sling 523 of the sling mechanism 52. Then, the two sides of the sling mechanism 52 are respectively connected to the connecting mechanism 53 and the adjusting mechanism 53.

[0004] However, in order for the sling connector 534a and the sling pressure plate 534b of the adjustment mechanism 53 to be clamped to the sling 523 of the coiling mechanism 52, the user needs to use a hand tool to connect the pressure plate screw 534c to both the sling connector 534a and the sling pressure plate 534b simultaneously. Similarly, to separate the coiling mechanism 52 from the adjustment mechanism 53, the user also needs to use a hand tool to first loosen the pressure plate screw 534c, so that the sling pressure plate 534b is separated from the sling connector 534a, and then the sling 523 can be detached from the sling connector 534a and the sling pressure plate 534b. Therefore, both the installation process of the coiling mechanism 52 on the adjustment mechanism 53 and the disassembly process of the coiling mechanism 52 off the adjustment mechanism 53 require the use of hand tools, which undoubtedly increases the number of steps in the installation and disassembly processes, and also increases the complexity and time consumption of the installation and disassembly processes, which will cause a certain degree of inconvenience to the user.

[0005] Furthermore, each time the snare mechanism 52 is installed on the adjustment mechanism 53, the positions where the strap connecting seat 534a and the strap pressure plate 534b of the adjustment mechanism 53 clamp the strap 523 are different each time. This results in the multiple snares 522 of the snare mechanism 52 being in different tension states, which in turn affects the sound quality produced when the conventional snare drum 50 is struck. Specifically, when the position where the strap connecting seat 534a and the strap pressure plate 534b clamp the strap 523 is closer to the snare connecting plate 521 of the snare mechanism 52, the tension of the multiple snares 522 will be too tight, resulting in the sound quality produced when the conventional snare drum 50 is struck. If the sound is too high-pitched, or conversely, if the position of the strap 523 clamped by the strap connector 534a and the strap pressure plate 534b is too far away from the resonant wire connector 521 of the resonant wire mechanism 52, the tension of the multiple resonant wires 522 will be too loose, resulting in a sound that is too low and unclear when the conventional snare drum 50 is struck. Therefore, if the position of the strap connector 534a and the strap pressure plate 534b clamping the strap 523 is incorrect, the snare drum 40 will not produce the desired sound. The user needs to repeatedly reinstall the resonant wire mechanism 52 onto the adjustment mechanism 53. However, repeated installation and adjustment not only increase the complexity of operation, but also significantly increase the time cost. Summary of the Invention

[0006] The main objective of this invention is to improve the structural design of the sling connection body, enabling the retractor mechanism to be connected and disassembled without any hand tools. This simplifies the assembly and disassembly process, allowing users to quickly detach the retractor mechanism from the improved sling connection body by hand. Furthermore, each time the retractor mechanism is installed on the improved sling connection body, the tension of the retractor wire is maintained within an appropriate range, ensuring that the snare drum produces an ideal sound when struck. This effectively prevents the snare drum's tone from being deviated due to excessive tension or looseness of the retractor wire.

[0007] The secondary objective of this invention is to improve the structural form of the opening and closing body, so that the improved opening and closing body can drive the movable body to move in multiple stages, allowing the degree of attachment of the multiple sound wires of the sound wire mechanism to the drumhead of the snare drum to vary in a variety of ways. This not only effectively expands the range of snare drum timbre variations, but also improves the diversity of performance.

[0008] Another objective of this invention is to improve the structural form of the adjustment mechanism to reduce the friction between the opening / closing body and the movable body, so that the opening / closing body can smoothly drive the movable body to move, thereby reducing the risk of malfunction between the opening / closing body and the movable body.

[0009] Another objective of this invention is to improve the structural form of the sling connection body. The improved sling connection body can be used for both rope-like slings and sheet-like slings, allowing the sling connection body to be flexibly matched with different types of slings. Thus, both the looping mechanism with rope-like slings and the looping mechanism with sheet-like slings can be connected to the improved sling connection body.

[0010] Another objective of this invention is to improve the coordination between the opening / closing body and the movable body to ensure that the opening / closing body can drive the movable body every time. This ensures that during the process of the opening / closing body moving the movable body to adjust the adhesion between the multiple strings of the string mechanism and the drumhead of the snare drum, the opening / closing body can always maintain effective contact with the movable body, effectively avoiding jamming between the opening / closing body and the movable body, which would prevent the opening / closing body from moving the movable body.

[0011] To achieve the aforementioned objective, the present invention provides a lead wire adjustment device, which includes a lead wire mechanism and an adjustment mechanism.

[0012] The aforementioned rattle mechanism has a rattle assembly and two straps connected to the rattle assembly. The aforementioned adjustment mechanism includes: a support body, a movable body, a strap connecting body, and an opening / closing body. The support body is connected to a drum shell. The movable body is movably connected to the support body, allowing the movable body to move relative to the support body. The strap connecting body moves synchronously with the movable body and is provided with a hook portion and a contact portion. The hook portion forms a hooking space, allowing the opening / closing body to drive the movable body to move.

[0013] The sling can extend across the contact portion from the cord assembly and hook onto the hook portion, so that the hooking space can accommodate a portion of the sling, and the other portion of the sling can simultaneously contact the contact portion.

[0014] In this embodiment, the sling connecting body has a sling connecting seat and a sling connecting wheel. The sling connecting seat is recessed to form two connecting grooves, and the connecting grooves are used to accommodate a portion of the sling, so that a portion of the sling can contact the wall of the connecting groove to form the contact portion. The sling connecting wheel has a connecting wheel shaft portion close to the sling connecting seat and a connecting wheel wheel portion away from the sling connecting seat, and the hooking space is formed between the connecting wheel shaft portion and the connecting wheel wheel portion, so that the sling connecting wheel forms the hook portion.

[0015] The aforementioned sling connecting wheel is located between two connecting grooves, and the height of the sling connecting wheel at its highest point is lower than the height of the connecting grooves. The sling connecting body further includes a sling pressure plate, a pressure plate screw, and a connecting wheel connector. A screw rod of the pressure plate screw passes through the sling pressure plate to connect to the sling connecting seat, such that the screw head of the pressure plate screw and the sling connecting seat are clamped together in the sling pressure plate. The sling pressure plate has a recessed pressure plate space on the side facing the sling connecting seat. The connecting wheel connector has a connecting head located inside the pressure plate space and a connecting rod formed at one end of the connecting head. The connecting rod is located outside the pressure plate space and connects to the connecting wheel shaft.

[0016] Furthermore, the aforementioned sling connector is provided with a first fixed seat surface that contacts the aforementioned sling pressure plate and a second fixed seat surface that forms the aforementioned connecting groove. The aforementioned connecting groove has a first turning surface adjacent to the aforementioned first fixed seat surface and a groove bottom surface spaced below the aforementioned second fixed seat surface. When the aforementioned sling is simultaneously placed inside the aforementioned hook space and inside the aforementioned connecting groove, the aforementioned sling contacts the aforementioned first turning surface to form a first bend. The aforementioned connecting groove has a second turning surface on the side of the aforementioned connecting groove away from the aforementioned first turning surface, and the aforementioned sling contacts the aforementioned second turning surface to form a second bend spaced apart from the aforementioned first bend.

[0017] Furthermore, the movable body has a movable rod passing through the bearing body and a connecting rod intersecting the movable rod. The opening and closing body is recessed to form an opening and closing track into which the connecting rod can pass, and is pivotally connected to the bearing body, so that the opening and closing body can rotate relative to the bearing body about a rotation axis. The opposite sides of the opening and closing track are respectively provided as a track proximal end close to the rotation axis and a track distal end away from the rotation axis. A track wall surface that can contact the connecting rod is formed from the track proximal end toward the track distal end. When the opening and closing body rotates relative to the bearing body, the connecting rod can selectively move along the track wall to the track proximal end or track distal end, thereby the connecting rod can move closer to or further away from the rotation axis, allowing the movable rod to move relative to the bearing body.

[0018] The aforementioned opening and closing body has an opening and closing pivot hole communicating with the aforementioned opening and closing track. The opening and closing pivot hole is adjacent to the near end of the aforementioned track. The aforementioned supporting body has a pivot rod that can pass through the opening and closing pivot hole and a pivot rod groove formed from the recess of the aforementioned pivot rod. When the aforementioned connecting rod moves toward the near end of the aforementioned track through the rotating opening and closing body, the aforementioned connecting rod will enter the interior of the aforementioned pivot rod groove. When the aforementioned connecting rod moves toward the far end of the aforementioned track through the rotating opening and closing body, the aforementioned connecting rod will leave the interior of the aforementioned pivot rod groove. The aforementioned opening and closing track is further provided with a track recess between the near end and the far end of the aforementioned track. The track recess is used to accommodate a portion of the aforementioned connecting rod, so that the aforementioned connecting rod can temporarily stop moving inside the aforementioned opening and closing track.

[0019] However, the aforementioned adjustment mechanism further includes a return spring, which is disposed between the bearing body and the movable body and can deform, so that the return spring can generate a return force acting on the movable body, so that the linkage rod can continuously contact the track wall through the return force.

[0020] The adjustment mechanism further includes an adjustment body that can pass through the linkage rod and be helically engaged with the sling connection body, so that when the adjustment body rotates relative to the movable body, the sling connection body can selectively move closer to or further away from the movable body.

[0021] Finally, the linkage has a linkage member connected to the movable rod 321 and a wheel made of non-metallic material. The wheel is installed at the end of the linkage member and can contact the track wall to reduce the friction between the linkage and the opening / closing track.

[0022] The invention is characterized by the fact that the sling connection body of the adjusting mechanism is provided with a hook part and a contact part, and the sling of the resonant mechanism can be hooked onto the hook part by crossing the contact part from the resonant assembly of the resonant mechanism, so that the hooking space can accommodate part of the sling, while the other part of the sling can contact the contact part. In this way, the resonant mechanism and the sling connection body can be disassembled and assembled without any hand tools, which effectively simplifies the disassembly and assembly process between the resonant mechanism and the sling connection body. In addition, the user can quickly disassemble and detach the resonant mechanism from the sling connection body by hand. Furthermore, when the sling of the resonant mechanism is hooked onto the hook part each time, the tension of the resonant can be maintained within an appropriate range so that the snare drum can produce an ideal sound when it is struck, thereby effectively avoiding damage to the sound quality of the snare drum caused by excessive tension or looseness of the resonant.

[0023] Furthermore, the opening and closing body is pivotally connected to the supporting body, and the opening and closing body forms an opening and closing track through which the linkage rod of the movable body passes. This allows the opening and closing body to rotate relative to the supporting body, thereby driving the movable body to move along the track wall of the opening and closing track. In addition, the opening and closing track has a track recess between the near end and the far end of the track. When the linkage rod is located in the track recess, the track recess can accommodate a part of the linkage rod, allowing the linkage rod to temporarily stop moving inside the opening and closing track. This mechanism allows the opening and closing body to drive the movable body to move in multiple stages, allowing for various changes in the adhesion between the multiple snare wires of the snare wire mechanism and the lower drumhead of the snare drum. This not only effectively expands the range of snare drum timbre variations but also enhances the diversity of performance.

[0024] In addition, the linkage wheel is made of non-metallic material, which significantly reduces the friction between the linkage and the opening and closing track when the wheel contacts the track wall. This allows the opening and closing body to smoothly drive the movable body to move, thereby reducing the risk of malfunction between the opening and closing body and the movable body.

[0025] However, the sling connection body mainly consists of a sling connection seat, a sling connection wheel, a sling pressure plate, pressure plate screws, and a connection wheel connector. The pressure plate screws pass through the sling pressure plate to connect to the sling connection seat, so that the sling pressure plate and the sling connection seat can be clamped to the sheet sling. The sling connection wheel is connected to the connection wheel connector that is clamped by the sling pressure plate and the sling connection seat. Thus, the sling connection wheel can form a hook part 331 to be hooked by the rope sling. In this way, the sling connection body can be used for both rope slings and sheet slings, allowing the sling connection body to be flexibly matched with different types of slings.

[0026] Furthermore, the adjustment mechanism is equipped with a return spring between the supporting body and the movable body. The return spring can push the movable body so that the linkage rod of the movable body can continuously contact the track wall of the opening and closing track. This ensures that during the process of the opening and closing body driving the movable body to move and adjust the adhesion between the multiple strings of the string mechanism and the drumhead of the small drum, the opening and closing body can always maintain effective contact with the movable body. This effectively avoids jamming between the opening and closing body and the movable body, which would prevent the opening and closing body from driving the movable body to move.

The connecting rod 337b extends from one end of the connecting head 337a to the outside of the pressure plate space 335a, such that a portion of the connecting rod 337b is located outside the pressure plate space 335a. A portion of the sling connecting wheel 338 is located near the sling connecting seat 333 and is configured as a connecting wheel axle 338a, while the remaining portion of the sling connecting wheel 338 is located away from the sling connecting seat 333 and is configured as a connecting wheel wheel portion 338b with a larger profile than the connecting wheel axle 338a. The connecting wheel axle 338a is connected to the connecting wheel... The connecting rod portion 337b allows the sling connecting wheel 338 to be located between the two connecting grooves 333c of the sling connecting seat 333, thereby making the highest point of the sling connecting wheel 338 lower than the height of the connecting grooves 333c. In this embodiment, the two connecting grooves 333c form the contact portion 332 of the sling connecting body 33, and a hooking space 331a for the hook portion 331 is formed between the connecting wheel axle portion 338a and the connecting wheel portion 338b, so that the sling connecting wheel 338 forms the hook portion 331 of the sling connecting body 33. As shown in FIG10, when the right sling 122 of the sling mechanism 10 can cross the contact portion 332 from the sling assembly 11 of the sling mechanism 10 and hook onto the hook portion 331, the right sling 122... A portion of the sling 122 is located between the connecting wheel axle portion 338a and the connecting wheel portion 338b, while another portion of the right sling 122 is located inside the connecting groove 333c to contact the wall surface of the connecting groove 333c. At the same time, different positions of the right sling 122 will contact the first and second turning surfaces 333e and 333f of the sling connecting seat 333 respectively, so that the right sling 122 forms a first bend 122a and a second bend 122b spaced apart from each other. As shown in the figure, the first bend 122a contacts the first turning surface 333e and is adjacent to one side of the connecting groove 333c, while the second bend 122b contacts the second turning surface 333f and is adjacent to the other side of the connecting groove 333c.

[0037] Please refer to Figures 6, 7, 8, and 11. The opening / closing body 34 of the adjusting mechanism 30 is pivotally connected to the supporting body 31 of the adjusting mechanism 30, allowing the opening / closing body 34 to rotate relative to the supporting body 31 about a rotation axis L parallel to the X-axis. The rotating opening / closing body 34 drives the movable body 32 to move. As shown in the figures, the opening / closing body 34 has two parts: an opening / closing turntable 341 and an opening / closing cover 342. One side of the opening / closing turntable 341 is recessed to form an opening / closing track 341a. The opening / closing turntable 341 extends from the opening / closing track 341a along the rotation axis L to form an opening / closing pivot hole 341b communicating with the opening / closing track 341a. The opposite sides of the opening / closing track 341a are respectively provided as a track proximal end 341c and a track distal end 341d. The opening / closing track 341a extends from the track proximal end 341c towards the track. The distal end 341d forms a curved track wall 341e, while the opening and closing track 341a is recessed at the position of the track wall 341e to form a track notch 341f between the proximal end 341c and the distal end 341d. In this embodiment, the opening and closing turntable 341 is sleeved on the pivot rod 313b of the supporting body 31, so that the pivot rod 313b passes through the opening and closing pivot hole 341b from the opening and closing track 341a, allowing the opening and closing turntable 341 to be pivotally connected to the pivot rod 313b. At the same time, the wheel 322b of the connecting rod 322 penetrates into the interior of the opening and closing track 341a to contact the track wall 341e of the opening and closing track 341a, so that the friction between the connecting rod 322 and the opening and closing track 341a can be effectively reduced. The opening and closing cover 342 is locked to the pivot rod 313b to prevent the opening and closing turntable 341 from disengaging from the pivot rod 313b.

[0038] Please refer to Figures 6, 7, and 8. The adjusting body 35 of the adjusting mechanism 30 passes through the upper fixed opening 311a of the supporting body 31 and into the movable rod 321 of the movable body 32, allowing the adjusting body 35 to rotate relative to the supporting body 31. The adjusting body 35, located inside the movable rod 321, is helically engaged with the connecting guide post 334 of the connecting body. Therefore, when the adjusting body 35 rotates relative to the movable body 32, the sling connecting body 33 can selectively move closer to or further away from the movable body 32. Furthermore, the return spring 36 of the adjusting mechanism 30 is located inside the bearing sleeve 312 of the supporting body. Furthermore, one end of the return spring 36 contacts the inner wall of the bearing fixed seat 311, while the other end of the return spring 36 contacts the connecting member 322a of the connecting rod 322, so that the return spring 36 is disposed between the bearing body 31 and the movable body 32. When the return spring 36 is located between the bearing body 31 and the movable body 32, the return spring 36 can deform, and the deformed return spring 36 can generate a return force F acting on the movable body 32, so that the wheel 322b of the connecting rod 322 can continuously contact the track wall 341e of the opening and closing track 341a through the return force F.

[0039] Please refer to Figures 12A, 12B, 12C, 12D, 12E, and 12F for a specific application of adjusting the adhesion between the lower drumhead 45 of the snare drum 40 and the plurality of resonant wires 113 of the resonant wire mechanism 10. First, as shown in Figures 12A and 12B, the wheel 322b of the linkage 322 contacts the far end 341d of the track of the opening and closing track 341a through the reset force F of the return spring 36. This causes the linkage 322 to move away from the opening and closing pivot hole 341b of the opening and closing turntable 341. Consequently, the linkage 322 will be located at the lower end of the right fixed slot 311b of the bearing fixing seat 311, so that the adhesion of the plurality of resonant wires 113 to the lower drumhead 45 can be minimized. As a result, when the upper drumhead 43 of the snare drum 40 is struck, the vibration of the plurality of resonant wires 113 can be weakened, which can relatively increase the sustain time of the resonant wires 113.

[0040] As shown in Figures 12C and 12D, the opening / closing turntable 341 of the opening / closing body 34 rotates counterclockwise, causing the rotating wheel 322b of the connecting rod 322 to move along the track wall 341e of the opening / closing track 341a inside the track 341a. As the rotating wheel 322b moves, it gradually approaches the opening / closing pivot hole 341b of the opening / closing turntable 341. During the movement of the rotating wheel 322b along the track wall 341e, the movable body 32 of the adjusting mechanism 30 and the sling connecting body 3 of the adjusting mechanism 30... 3. The mechanism moves upward synchronously to tighten the plurality of resonant wires 113 of the resonant wire mechanism 10, thereby improving the adhesion between the lower drum skin 45 of the adjusting small drum 40 and the plurality of resonant wires 113 of the resonant wire mechanism 10, further enhancing the resonance effect of the resonant wires 113. When the rotating wheel 322b is aligned with the track recess 341f located in the opening and closing track 341a, a portion of the rotating wheel 322b will enter the interior of the track recess 341f, allowing the track recess 341f to accommodate a portion of the connecting rod 322 so that the connecting rod 322 can temporarily stop moving inside the opening and closing track 341a.

[0041] As shown in Figures 12E and 12F, the opening and closing turntable 341 of the opening and closing body 34 continues to rotate counterclockwise, causing the wheel 322b of the linkage 322 to move along the track wall 341e of the opening and closing track 341a from the track recess 341f toward the far end 341d of the opening and closing track 341a. Consequently, the linkage 322 gradually approaches the uppermost end of the right fixed slot 311b of the bearing fixing seat 311, thus linking... The rod 322 will enter the pivot groove 313c of the pivot rod 313b. When the wheel 322b is located at the far end 341d of the track, the movable body 32 will stop moving relative to the supporting body 31, thereby maximizing the tightness of the plurality of sound wires 113. The adhesion between the plurality of sound wires 113 and the lower drumhead 45 can be maximized, so that when the upper drumhead 43 of the snare drum 40 is struck, the vibration of the plurality of sound wires 113 can be enhanced.

[0042] As shown in Figures 12G and 12H, the opening and closing turntable 341 of the opening and closing body 34 rotates clockwise, causing the wheel 322b of the connecting rod 322 to move along the track wall 341e of the opening and closing track 341a from the near end 341c of the track towards the far end of the track. As a result, the connecting rod 322 gradually approaches the lower end of the right fixed slot 311b of the bearing fixed seat 311, and thus the connecting rod 322 moves away from the pivot groove 313c of the pivot rod 313b. When the wheel 322b is located at the near end 341c of the track, the movable body 32 stops moving relative to the bearing body 31, thereby reducing the adhesion between the lower drum skin 45 and the plurality of sounding wires 113.
